EXECUTIVE SUMMARY
The Orange County Sanitation District is required to comply with the State Water Resources Control
Board Order No. 2006-0003-DWQ adopted May 2, 2006,entitled Statewide General Waste Discharge
Requirements for Sanitary Sewer Systems." Information on the State's SSO Reduction Program can
be found at: htm://www.waterboards.ca.gov/water issues/programs/sso/index.shtml.
The purpose of the Order is to prevent Sanitary Sewer Overflows (SSO) or sewer spills by
establishing a statewide Monitoring and Reporting Program (MRP) and requiring each local or
regional sewer agency to create and implement their own Sewer System Management Plan (SSMP)
based on the mandatory requirements of the Order.
The MRP requires each local or regional sewer agency to appoint a legally responsible official and
establish a monitoring and reporting organization to monitor and report all SSOs in accordance with
the requirements of the Order and to have the LRO certify the SSO report using the California
Integrated Water Quality System (CIWQS) website in the timeframe required by the Order. If no
SSOs occur during the course of any given month,the LRO is required to fill out, certify and send
via the CIWQS website a"No Spill Certification" documenting that there were no SSOs for the
month reported.
To comply with the essence of this Order:
■ OCSD has enrolled and applied for coverage and agrees to comply with all conditions
and provisions of this Order.
• OCSD shall take all feasible steps to eliminate SSOs. In the event that an SSO does
occur,OCSD shall take all feasible steps to contain and mitigate the impacts of an
SSO.
• In the event of an SSO,OCSD shall take all feasible steps to prevent untreated or
partially treated wastewater from discharging from storm drains into flood control
channels or waters of the United States by blocking the storm drainage system and by
removing the wastewater from the storm drains.
• OCSD shall report all SSOs in accordance with Section G of the WDR.
• OCSD shall properly,manage, operate, and maintain all pans of its sanitary sewer
system, and shall ensure that the system operators (including employees, contractors,
or other agents) are adequately trained and possess adequate knowledge, skills,and
abilities.
• OCSD shall allocate adequate resources for the operation,maintenance,and repair of
its sanitary sewer system,and a proper rate structure,accounting mechanisms,and
auditing procedures to ensure an adequate measure of revenues and expenditures.
These procedures are in compliance with applicable laws and regulations and comply
with generally acceptable accounting practices.
• OCSD shall provide adequate capacity to convey base flows and peak flows,including
flows related to wet weather events.

CHAPTER 4—LEGAL AUTHORITY
This chapter describes the legal authority to implement the SSMP.
OCSD must demonstrate,through sanitary sewer system use ordinances,service agreements, or other
legally binding procedures, that it possesses the necessary legal authority to:
(a) Prevent illicit discharges into its sanitary sewer system (examples may include
infiltration and inflow), stormwater,chemical dumping,unauthorized debris and cut
roots,etc.).
The inflow sources may include items such as sump pumps,roof leaders,yard and
stairwell drains,satellite systems,or any other materials that adversely affect the
performance of the collection system and/or the Waste Water Treatment Plant.
(b) Require that sewers and connections be properly designed and constructed. OCSD's
Engineering Department develops and maintains construction standards for OCSD
pumping stations and collection system. These legally binding documents will also
ensure that testing is conducted and baseline condition assessment completed for
sewer system construction projects (air test,CCTV,pump station performance,etc.),
and that procedures are in place to transfer the resulting test data to the end user.
These should also require development and implementation of technical requirements
and training standards for construction inspectors.
(c) Ensure access for maintenance,inspection,or repairs for portions of the lateral
owned or maintained by the Public Agency.
(d) Limit the discharge of FOG and other debris that may cause blockages.
The FOG control program will be for commercial,industrial,and institutional users
and will combine source and field control to reduce SSOs caused by the discharge of
FOG to the collection system.
(e) Enforce its sewer ordinances.
4.1 Compliance Surnimary
This SSMP complies with the Order requirements for legal authority under the following enacted
ordinances/resolutions or agency policies.
(a) Ordinance No. OCSD-48 "Wastewater Discharge Regulations"effective July 1,
2016,replacing"Waste Discharge Regulations"effective September 23,2009. Article
2 of Ordinance No. OCSD-48 has general prohibitions,limits and requirements for
discharge which apply to all users of the OCSD sewer collection facilities. This
Ordinance complies with and meets the minimum legal authority for OCSD required
by the General WDR
(b) The WDR requires that OCSD sewers and connections be properly designed and
constructed. The design and construction requirements for OCSD sewers are kept
and managed by the OCSD Engineering Department. These include the Engineering
H:\depu\es\610\...\SSMP Volume 1_2016 Update Final January 2019
4-2 Legal Authority
Design Guidelines, the CAD manual, the Master Specifications,Process Control
Software Standards, Standard Drawings, and Instrumentation&Equipment Tagging
Information. The construction,inspection and testing of new lateral connections and
bypass piping facilities is governed by the permit and related construction standards,
and legally enforced through OCSD's connection permit program through the
Engineering Department,as authorized by OCSD's Charter. Documentation for
these requirements is located at the permit counter in the Engineering Department at
OCSD Reclamation Plant No. 1.
(c) To ensure access for maintenance,inspection,or repairs for portions of the lateral
owned or maintained by the Public Agency OCSD adopted Resolution No. OCSD
07-14: "Adopting a Policy Regarding Maintenance of Unobstructed Access to District
Easements" on June 27,2007. While OCSD does not permit direct lateral connection
to its regional sewers,it has been OCSD practice to accept responsibility for
maintaining the first four feet of local satellite agency pipelines connecting to OCSD
sewers. OCSD issues permits to property owners and contract for work according to
OCSD standards. Approved design and construction standards are situated in
electronic files,and are also available on compact disc. A special standard derived
from the master specifications is issued for property owner contractors and is
available at the permit counter in the Engineering Department at OCSD Reclamation
Plant No. 1.
(d) To limit the discharge of FOG and other debris that may cause blockages;OCSD
established two comprehensive policies regarding limitation of the discharge of FOG
into the OCSD sewer collection facilities. These are: (1) Ordinance No. OCSD-25
"Fats, Oils, and Grease (FOG) Ordinance For Food Service Establishments",
effective January 1,2005; and (2) Resolution No. OCSD 05-04"Establishing Fats,
Oils,and Grease Control Program Fees Applicable To Food Service Establishments",
effective May 1,2005. Together these ordinances provide OCSD with the legal
authorities necessary to limit FOG and debris entering into the OCSD sewer
collection system.
(e) In accordance with the enforcement provisions of its discharge ordinances,
including OCSD-25 and OCSD48, OCSD established and actively manages the
source control function within the Resource Protection Division. This division of the
OCSD Environmental Services Department also enforces applicable sections of the
State of California and United States of America state and federal laws relating to
source control and violation of its sewer ordinances and resolutions.
4.2 Compliance Documents
The legal authority for enacting the SSMP programs and policies are included in the following
documents:
• FOG Ordinance No. OCSD-25 (Appendix El)
■ Wastewater Discharge Regulations Ordinance No. OCSD-48 (Appendix E2)

■ FOG Fee Resolution No. OCSD 05-04 (Appendix E3)
• Legal authority,as outlined in OCSD's Charter,is on file in the OCSD Clerk of the
Board's office
• Construction contracts, standard testing and inspection requirements,Master
Specifications section 02627 Manhole and Precast Vault Construction,other sections
4.3 Roles and Responsibilities
The roles and responsibilities for enforcement of the legal authority to enact the SSMP programs and
policies is derived from acts of OCSD's governing Board. Legal interpretation of the enabling state
legislation giving authority to OCSD is provided by OCSD General Counsel.
During the course of implementing the FOG Source Control Program,programmatic changes are
anticipated which may necessitate revision of FOG Ordinance No. OCSD-25 and FOG Fee
Resolution No. OCSD 05-04. The OCSD Resource Protection Division is responsible for
periodically reviewing and updating these documents, as the need arises, to ensure that the legal
authority is comprehensive and covers all aspects of the FOG Source Control Program.
Wastewater Discharge Regulations Ordinance No. OCSD-48 is OCSD's main ordinance for
regulating sewer use and wastewater discharges in the satellite cities and sewering agencies that drain
to OCSD's system. These include agreements with SAWPA and LA County Sanitation Districts,and
controlling inflow and infiltration and illegal connections to the system. The OCSD Resource
Protection Division is responsible for maintaining and updating, or amending this ordinance.

CHAPTER 5—OPERATION AND MAINTENANCE PROGRAM
This chapter describes the OCSD activities regarding management of engineering data,maps of the
sanitary sewer system,operations and preventive maintenance,rehabilitation and replacement
program, training programs,and equipment and replacement part inventories.
5.1 Mapping
OCSD maintains electronic models of facilities and assets. The concept with roles and
responsibilities is described in Facility Model Maintenance Management Plan (Appendix KI).
■ OCSD Sewer Atlas—This is an electronic facility model that includes all of the sewer
lines,manholes,diversion structures, force mains, siphons, force main valves, and
pump stations of the OCSD collection system. The Sewer Atlas can be viewed
through a variety of methods. The sewers and manholes can be viewed with either a
plain background or a photographic background with the streets and sewer lines
superimposed over the background. Maintenance procedures for the Sewer Atlas are
described in Appendix K2.
• Map Books and Electronic Map Book—Map Books are composed of a set of printed
maps from the Sewer Atlas. The EMB is an on-line form of the Map Books and
allows the user to link to adjacent maps and drawings.
• Electronic Document Management System—allows access to scanned image file of
drawings generated from capital projects from the collection system.
■ Enterprise-wide Geographical Information System—an on-going program linking
various heretofore independent database functions and related information
graphically,to more easily find and correlate such things as easement documents with
the electronic mapping information and cataloging of useful and connected
information.
When discrepancies are identified between the field conditions and electronic records, staff completes
the Field Discrepancy Form (Appendix K3),and updates are made by the responsible party.
5.1.1 Compliance Scunmary. The asset inventory of all collection system assets is contained in
OCSD's GIS,which is maintained as a part of OCSD's Enterprise Information Management
program. A subset of the asset register is contained in the Computerized Maintenance Management
System. The CMMS-resident assets are those assets that have or may have scheduled maintenance
activities associated with them to ensure their performance level is maintained,and that they reach
their expected useful lives. The assets contained in the GIS,CMMS,and other asset-based data
repositories (such as the Supervisory Control and Data Acquisition) are all connected by the use of
unique identifiers known as structure ID's,which are associated with fixed process locations and
equipment numbers. The collection system assets contained in the CMMS have various types of
scheduled maintenance activities assigned to them; these activities may include any combination of
investigation of problem, condition assessment,and preventive maintenance activities necessary to
properly maintain the assets.
H:\depu\es\...\SSMP Vol—1_M16 Update Final Jm g2017
5-2 Operation and Maintenance Program
Every two years OCSD issues an updated new Asset Management Plan that details asset management
activities,and identifies asset management improvement strategies and projects being considered by
OCSD. The current Asset Management Plan is contained in Appendix H.
Treatment Plant-related Operation and Maintenance manuals and Equipment Service Manuals have
been put into an electronic format. Standard Operating Procedures currently are being developed.
These renewed resources are being made available to all OCSD employees online through SharePoint
and the OMaP system,which is accessed from the OCSD home page. Under the O&M Director's
responsibility, OMaP is updated and expanded to match any changes made to plant processes and
equipment. Upgrades for the equivalent Collection Facility service documents are underway.
5.1.2 Compliance Documents. The documents supporting compliance with the requirements for
mapping are as follows:
• Integrated Emergency Response Plan (copies located in the OCSD Safety Office,
the Control Centers and Emergency Operations Centers at Reclamation Plant No. 1
and Treatment Plant No. 2);
• Electronic Map Book and OCSD Sewer Atlas;
• Flow monitoring reports and records.
Pump station and ancillary equipment drawings are on file in the Engineering Department. Copies of
drawings are available for staff use in the EDMS,and on physical stick files located in the
Engineering Department. The Information Technology Department is responsible for maintaining
the electronic version of all record drawings,EMB, and the Sewer Atlas.
5.1.3 Roles and Responsibilities. The annual budget document contains the chart that identifies
the positions in general, and also those positions specifically responsible for OCSD's collection
system assets. The Enterprise GIS Business Unit is responsible for maintaining the OCSD mapping
systems. The Engineering Department is responsible for acquiring drawings during capital projects.
The Instrumentation and Electrical Division identify the management, supervision,and field
positions that are responsible for identifying the various tasks required to support the proactive
maintenance program for OCSD assets. This information is posted on the OCSD website and can
be accessed at htW://www.ocsd.com. Program responsibilities are also presented in Appendix C.
5.2 Preventive Maintenance Program
OCSD has an on-going preventive and corrective maintenance program,and is in the process of
developing a comprehensive life-cycle asset management program. OCSD has an IERP that includes
procurement procedures and inventories for critical equipment under various scenarios. OCSD's
current reliability shows that the availability and stock levels of spare parts has been sufficient,and no
changes are recommended at this time.
OCSD has prepared the PMP document,which covers the assets managed in the sanitary sewer
system, and is based on an approach that combines predictive,preventive,and corrective
maintenance strategies and established BMPs. Copies of the PMP and Collection Facilities O&M
Vehicle Inventory are included in Volume II Appendices I1 and I2,respectively.
J—,M17 H:\d,t\u\610\...\SSb V.I—.1_2016U da,e Final
Operation and Maintenance Program 5-3
One component of the PMP development process is the resource gap analysis. OCSD continually
reviews resource needs through the annual budget process,the asset management program,
rehabilitation and replacement program,and capacity evaluations. The PMP also contains a review of
existing business and work practices; this review is on-going. The work is focused on validating
existing or making improvements to the current data management,data analysis, and supporting
decision-making processes. This will ensure that the maintenance divisions provide consistent,
effective,and efficient maintenance support for OCSD assets. In light of the expanded maintenance
program requirements,the current performance management processes will be reviewed to determine
continued alignment;maintenance reports will be modified as needed.
The criticality assessment of collection system assets is included in the PMP Project Plan. This
assessment is in progress and has been integrated into the plan in a three-phase approach. The initial
phase was conducted on pump station assets and force mains as part of the pump station
maintenance task analysis,with the results being entered into the CMMS. The second phase is
currently underway and will rate the criticality/condition of the collection system gravity pipes,and
the final phase will be the rating of the criticality/condition of the gravity system manholes and other
structures. The data from the second and third phases will be stored in the Business Risk Exposure
Analysis models for gravity pipes and manholes. The information on pump station asset
condition/criticality will be updated on demand,while the BREA models will be updated annually as
additional condition data becomes available.
5.2.1 Compliance Summary.The Collection Facilities O&M Division conducts various
maintenance activities to maintain collection system assets. As part of the work order closeout
process,all operational and structural condition information is recorded. This work history
documentation is analyzed to identify potential operational failures which could result in spills.
Maintenance tasks might be added,deleted,or altered based on the analysis findings. Tasks might be
altered by modifying the task work content,adjusting task intervals and/or adjusting task times to
compensate for the adverse conditions found. Work order closeout procedures are in place to ensure
that all work history is memorialized. As part of the preventive maintenance program analysis
process,observations related to grease build-up within the sewer collection facilities pipelines are
reported to the Environmental Compliance Division. The Environmental Compliance Division is
then responsible for further investigations to determine the cause of the identified grease build-ups,
as further addressed in Chapter 8 (Fats,Oils,and Grease Control Program).

CHAPTER 7—OVERFLOW EMERGENCY RESPONSE PLAN
OCSD has developed an overflow Emergency Response Plan that identifies measures to protect
public health and the environment. In addition, OCSD is part of the Countywide Area Spill Control
(CASC) Program for additional support on containment and cleanup in the flood control channels.
7.1 Compliance Summary
OCSD also maintains an SSO ERP which is updated as needed by the Collection Facilities O&M
Supervisor and reviewed and approved by the division Manager. SOPS are also updated by the
Collection Facilities O&M Supervisor for Emergency Response for SSOs and Spill Containment.
SOPS for notification are updated as needed by the Environmental Compliance staff and approved
by their division Manager. The SSO ERP includes,but is not limited to the following items:
(a) Proper notification procedures so that the primary responders and regulatory agencies
are informed of all SSOs in a timely manner;
(b) A program to ensure appropriate response to all overflows;
(c) Procedures to ensure prompt notification to appropriate regulatory agencies and
other potentially affected entities (e.g.,health agencies, regional water boards,water
suppliers,etc.) of all SSOs that potentially affect public health or reach the waters of
the State. All SSOs are reported in accordance with the MRP, the California Water
Code,other State Law, and other applicable Regional Water Board WDR or NPDES
permit requirements;
(d) Procedures to ensure that appropriate staff and contractor personnel are aware of and
follow the ERP and are appropriately trained;
(e) Procedures to address emergency operations, such as traffic and crowd control and
other necessary response activities; and
(f) A program to ensure that all reasonable steps are taken to contain and prevent the
discharge of untreated and partially treated wastewater to waters of the United States
and to minimize or correct any adverse impact on the environment resulting from the
SSOs,including such accelerated or additional monitoring as may be necessary to
determine the nature and impact of the discharge.
(g) A requirement for contractors to develop a Spill Prevention, Control,and
Countermeasure Plan,which includes spill notification and response protocols as
required by OCSD or guidance provided by OCSD to contractors in the event an
SSO occurs is noted in the OCSD Master Spec 02999 Temporary Handling of
Sewage.
Note: SSO sampling,if conducted,is performed by the OCHCA. In some instances,OCHCA may
request that OCSD conduct sampling. The first responders from the Laboratory,Monitoring&
Compliance Division carry equipment to collect samples if necessary.

CHAPTER 8—FATS,OILS,AND GREASE (FOG) CONTROL PROGRAM
Prior to implementation of the FOG Control Program,OCSD contracted the services of a
consultant to conduct a study to establish the building blocks for an effective FOG source control
program. The study,known as the Phase I Report(available from OCSD's Resource Protection
Division) was completed in July 2003 per the Regional Board 8 WDR Order. The report presented
twelve potential building blocks along with a draft ordinance which eventually served as the blueprint
for OCSD's FOG Control Program as well as the countywide FOG control effort executed through
OCSD's satellite cities and sewer agencies.
In order to limit the discharge of FOG and other debris that may cause sewer collection system
blockages or SSOs,and in compliance with the SWRCB Order No. 2006-0003-DWQ Order,adopted
May 2,2006,OCSD has prepared and implemented the following elements into their FOG Control
Program effort:
(a) An implementation plan and schedule for a public education outreach program that
promotes proper disposal of FOG;
(b) A plan and schedule for the disposal of FOG generated within the sanitary sewer
system service area. This may include a list of acceptable disposal facilities and/or
additional facilities needed to adequately dispose of FOG generated within a sanitary
sewer system service area;
(c) The legal authority to prohibit discharges to the system and identify measures to
prevent SSOs and blockages caused by FOG;
(d) Requirements to install GRD (such as traps or interceptors) design standards for the
GRDs,maintenance requirements,BMP requirements, record keeping and reporting
requirements;
(e) Authority to inspect grease producing facilities,enforcement authorities, and whether
OCSD has sufficient staff to inspect and enforce the FOG ordinance;
(1) An identification of sanitary sewer system sections subject to FOG blockages and
establish a cleaning maintenance schedule for each section (OCSD's Collection
Facilities O&M Division of the Facilities Support Services Department is responsible
for maintenance scheduling);and
(g) Development and implementation of source control measures, for all sources of
FOG discharged to the sanitary sewer system, for each section identified in (f) above.
8.1 Compliance Surnrnary
To address the WDR Order, OCSD passed a FOG Ordinance (Appendix El) to establish the legal
authority to prohibit Food Service Establishments from discharging FOG to the sewer system. The
Ordinance for Wastewater Discharge Regulations (Appendix E2) provides the uniform requirements
for users of OCSD's facilities. The resolution to establish fees for the FOG Program is included in
Appendix E3. In addition, OCSD assembled a model FOG source control program using the
H:\depu\es\610\...\SSMP V.1-1_2016 llpdeee Field J—,2019
8-2 Fats,Oils,and Grease (FOG) Control Program
building block components identified in the Phase I Report, and developed an enforcement
management system to resolve noncompliance issues in a fair and consistent manner. For a detailed
discussion of the program and its development see"Fats, Oils, and Grease Source Control Program
and Enforcement Management System,"Appendix F and"Basis for Program Development,
Program Components,and Policies,"Appendix GI in SSMP Volume II.
Based on recommendations from the Phase I report, OCSD retained a contractor to conduct an
additional study to field test three newer FOG control technologies (additives,nonconventional
grease traps,and interceptor monitoring devices) to determine whether these technologies are
effective and should be used in FOG control programs. The Phase II Report,published in March
2006, concluded that these technologies might be useful in instances where a below ground
interceptor was not practical. However,all of the studied control technologies had their limitations
and would require extensive maintenance and/or follow-up to remain effective over the long haul.
To date,none have been incorporated into OCSD's FOG control strategy.
As a regional agency with trunklines throughout Orange County, OCSD shares overlapping
operational jurisdiction throughout the cities and sewer agency districts within the county. In general,
OCSD owns and maintains the larger trunklines while the cities and agencies that form OCSD,own
and maintain the smaller laterals. OCSD relies on the cooperation and resources of the 27 satellite
cities and agencies to maintain the smaller laterals and to implement FOG control programs for the
FSEs that discharge directly to the local collection systems. Beginning May 2006,each city or sewer
agency was required to comply with the statewide WDR Order, and as a consequence, each agency
needed to develop and implement a FOG control program which suited its individual conditions and
needs. Though the specifics vary, the programs generally follow the basic approach of prohibiting
FOG discharges and mandating the use of kitchen Best Management Practices (BMPs) at the FSEs in
their jurisdictions.Appendix G3 summarizes the program elements implemented by the various
satellite cities and sewer agencies and provides a contact list for each agency and city.
Being the primary owner of both regional and local sewer lines in the northwest Tustin area, OCSD
assumed responsibility for initiating the FOG control commercial program and residential outreach.
In January of 2006, 13 satellite cities and agencies,along with OCSD, entered into an agreement with
OCHCA (see SSMP Volume II,Appendix G2 for a copy of the agreement) to expand the normal
ESE health inspection protocols to include FOG control elements. These inspections consist of
providing FOG control literature to the FSEs as well as generating a list of noncompliance
observations on a number of program elements including the presence of a garbage disposal,missing
drain screens,grease disposal records,missing signage,improper FOG disposal,missing grease
recycling container,and lack of BMP training records. OCHCA efforts on behalf of the participants
do not include enforcement or follow-up for noncompliance, or grease trap monitoring. The
following table details the 12 cities and agencies that continue to participate in the OCHCA FSE
inspection program as part of their FOG control strategy.

Satellite cities and agencies not shown on this list manage their own FOG programs and are also
subject to OCSD's Legal Authority provisions.
In July of 2011, all sewer assets in the City of Yorba Linda were transferred to the Yorba Linda Water
District,which assumed the FOG control responsibilities for that city. In July 2013, the Yorba Linda
Water District ended their involvement in the OCHCA FSE program, leaving OCSD and 11 other
cities and agencies still taking part. On April 13,2016, the Orange County Local Agency Formation
Commission approved East Orange County Water District's (EOCWD) application to accept the
transfer of the sewers within OCSD's Service Area 7,which included the Tustin area and several
adjacent unincorporated areas of Orange County. The transfer of all assets was completed in August
2016. This change in ownership also affected the responsibility for implementing the FOG control
program in the newly created service area. As of the transfer, OCSD is no longer the administering
authority for the program in the transfer area. OCSD continues to manage a limited FOG control
program for approximately 40 food service establishments that discharge directly of OCSD owned
trunklines in the City of Orange. EOCWD is continuing to participate in the OCHCA ESE program
as it transitions into the administering authority role.

OCSD's Collection Facilities O&M Division of the Operations &Maintenance Department has a
program to identify sections of the collection system subject to blockages,and a schedule for trouble-
spot cleaning as part of the preventive maintenance program. The review of existing FOG trouble-
spot conditions is a continuous process conducted as put of the cleaning program. Trouble-spots
that can be attributed to FOG are reported to the Resource Protection Division for investigation and
mitigation. Procedures were collaboratively developed by the Collection Facilities and Resource
Protection staff to ensure the timely reporting of trouble-spot modifications such as the discovery of
a new FOG trouble-spot or a change in the maintenance frequency of an existing site. In turn,the
Resource Protection Division forwards information related to the investigation and mitigation of
FOG-related trouble-spots back to the Collections Facilities O&M Division so the appropriate
adjustments can be made to the cleaning activities at that location.

CHAPTER 9—SYSTEM EVALUATION AND CAPACITY ASSURANCE PLAN
OCSD has prepared and implemented a CIP that provides hydraulic capacity of key sewer system
elements under peak flow conditions, as well as the appropriate design for storm or wet weather
events. At a minimum, the plan includes the following:
(a) Evaluation: The portions of the collection system that could experience or
contribute to an SSO discharge caused by hydraulic deficiency have been identified by
the Engineering Department's 2009 Facilities Master Plan,which was produced and
adopted in December 2009 using the OCSD "Hydraulic Model"program. Included in
the evaluation are estimates of peak flows (including from SSOs that escape from the
system) associated with conditions similar to those causing overflow events,estimates
of the capacity of key system components,hydraulic deficiencies (including
components of the system with limiting capacity),and the major sources that
contribute to the peak flows associated with overflow events.;
(b) Design Criteria: Where design criteria do not exist or are deficient,undertake the
evaluation identified in "a"above to establish appropriate design criteria;
(c) Capacity Enhancement Measures: The steps needed to establish a short- and
long-term CIP to address identified hydraulic deficiencies including prioritization,
alternatives analysis,and schedules;
(d) Schedule: OCSD shall develop a schedule of completion dates for all portions of the
CIP developed in (a-c) above. This schedule shall be reviewed and updated consistent
with the SSMP review and update requirements as described in Section D.14.
9.1 Compliance Summary
OCSD has an established CIP that includes the following
• Evaluation:The portions of the collection system that could experience or
contribute to an SSO discharge caused by hydraulic deficiency have been
identified by the Engineering Department's 2009 Facilities Master Plan,which
was produced and adopted in December 2009 using the OCSD "Hydraulic
Model' program. Included in the evaluation are estimates of peak flows
(including from SSOs that escape from the system) associated with conditions
similar to those causing overflow events,estimates of the capacity of key
system components,hydraulic deficiencies (including components of the
system with limiting capacity), and the major sources that contribute to the
peak flows associated with overflow events.
■ Capacity Enhancement Measures: OCSD has established a short- and long-term
CIP to address identified hydraulic deficiencies. The CIP includes project cost
estimates, project prioritization,alternatives analysis, and construction schedules.

9-2 System Evaluation and Capacity Assurance Plan
implementation schedules,and will include information on the performance of
measures that have been implemented.
OCSD has design standards and guidelines to ensure adequate capacity. OCSD's CIP assures that
older facilities are upgraded as needed to ensure adequate capacity through the system. These
programs are formally addressed and described more extensively in the Capacity Evaluation Plan,
which was submitted on April 24, 2009,and is included as Appendix M.
OCSD works under annual and long-range plans that have proven effective, and OCSD is not
currently experiencing capacity-related problems. Indications of possible capacity problems seen by
the Collections Facilities O&M Division are brought to the attention of the Engineering Department
for further evaluation.
9.2 Compliance Documents
The documents used for system evaluation and capacity assurance are as follows:
• Monthly SSO Reports
■ Source Control Annual Report

CHAPTER 10—MONITORING, MEASUREMENT,AND PROGRAM
MODIFICATIONS
This chapter describes OCSD measures and activities.
(a) Maintain relevant information that can be used to establish and prioritize appropriate
SSMP activities;
(b) Monitor the implementation and,where appropriate,measure the effectiveness of
each element of the SSMP;
(c) Assess the success of the preventive maintenance program;
(d) Update program elements, as appropriate,based on monitoring or performance
evaluations;and
(e) Identify and illustrate SSO trends,including: frequency,location,and volume.
10.1 Compliance Smmnary
OCSD has been reporting and keeping statistics on a0 SSOs for over a decade,and has been
monitoring some nationwide statistics. Although some elements of the measurement portion of the
program have not yet been developed,they will likely include an SSO-trending metric in the future.
OCSD utilizes the State of California's CIWQS database and mapping to track and illustrate trends of
SSOs. OCSD identifies the root cause of an SSO, such as structural problems,capacity,type of
debris,pumping facility component failure as these and other indicators are of value in monitoring
the effectiveness of the program and making improvements. If necessary,projects will be developed
to rehabilitate or replace system components based on sound asset management decisions.
OCSD has identified desired levels of service in our Board-adopted Strategic Plan related to sewer
spills,when they do occur:
■ a 2.1 Sanitary sewer spills per 100 miles;
• Contain sanitary sewer spills within 5 hours;
• Respond to collection system spills within 1 hour.
In addition,Safety goals are established for each division through the use of a Safety Scorecard. The
score is determined through staff completion of required training,documentation of safety incidences
in a timely manner,inspections of work areas on a quarterly basis, and regular reporting of near-miss
incidents. All OCSD staff are part of this program,including the Collection Facilities O&M
Division. In the event the safety metrics or OCSD levels of service are altered,the Collection
Facilities O&M Division will utilize the most current goals.
H:\depu\es\610\...\SSMP Vol-me 1_2016 Update Field January 2019
10-2 Monitoring,Measurement,and Program Modifications
OCSD monitors the implementation effectiveness of the SSMP elements through review at OCSD
stakeholder meetings. OCSD will also work to ensure that OCSD remains in compliance with the
WDR and make changes and updates to its SSMP,as necessary,based on audit evaluations.
10.2 Compliance Documents
The documents used for monitoring,measurement, and program modification requirements are as
follows:
• Sewer System Management Plan;
■ Flow Data;

CHAPTER 11—PROGRAM AUDITS
As part of the SSMP, the OCSD shall conduct periodic internal audits, appropriate to the size of the
system and the number of SSOs. At a minimum,these audits must occur every two years and a
report must be prepared and kept on file. This audit shall focus on evaluating the effectiveness of the
SSMP and the OCSD's compliance with the SSMP requirements identified in this subsection (D.13),
including identification of any deficiencies in the SSMP and steps to correct them.
Further clarification by the Stare Water Board about audit frequency includes:
The SSMP requires that each enrollee conduct an internal audit of their SSMP every twoyearr due by the
anniverrary date that the enrolleeigoverning body approved the SSMP. It it permissible jar an enrollee to
conduct their internal audit earlier than their anniverrary date. If an audit is conducted early the date that the
audit is due is still bared upon the anniversary date and not the date the last audit was completed Although
the internal audit does not have to be submitted to the state it is recommended that it be placed in the enrollee's
SSMP and may be requested by the SWRCB or the Regional Board at any time. In fact, the SWRCB is
routinely requesting a copy of the internal audit to arrest them in selechagpossible enrollees for inspection and
audit.
11.1 Compliance Summary
OCSD has an internal audit program that covers the WDR and its elements. OCSD's Environmental
Auditing Program Manager hires a third parry auditor to conduct repeating agency-wide audits.
Strategies to correct deficiencies,if identified,will be developed by the responsible OCSD division
with assistance from OCSD's WDR stakeholders.
OCSD meets with their satellite cities and agencies and discusses collaborative auditing approaches,
training,and lessons-leamed,pending the availability of resources.
11.2 Compliance Documents
The documents used for audit evaluations include the following
• OCSD Environmental Auditing Program Procedures Manual (Appendix Xl)

STATE WATER RESOURCES CONTROL BOARD
ORDER NO. 2006-0003-DWQ
STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS
FOR
SANITARY SEWER SYSTEMS
The State Water Resources Control Board, hereinafter referred to as "State
Water Board", finds that:
1. All federal and state agencies, municipalities, counties, districts, and other public
entities that own or operate sanitary sewer systems greater than one mile in
length that collect and/or convey untreated or partially treated wastewater to a
publicly owned treatment facility in the State of California are required to comply
with the terms of this Order. Such entities are hereinafter referred to as
"Enrollees".
2. Sanitary sewer overflows (SSOs) are overflows from sanitary sewer systems of
domestic wastewater, as well as industrial and commercial wastewater,
depending on the pattern of land uses in the area served by the sanitary sewer
system. SSOs often contain high levels of suspended solids, pathogenic
organisms, toxic pollutants, nutrients, oxygen-demanding organic compounds, oil
and grease and other pollutants. SSOs may cause a public nuisance,
particularly when raw untreated wastewater is discharged to areas with high
public exposure, such as streets or surface waters used for drinking, fishing, or
body contact recreation. SSOs may pollute surface or ground waters, threaten
public health, adversely affect aquatic life, and impair the recreational use and
aesthetic enjoyment of surface waters.
3. Sanitary sewer systems experience periodic failures resulting in discharges that
may affect waters of the state. There are many factors (including factors related
to geology, design, construction methods and materials, age of the system,
population growth, and system operation and maintenance), which affect the
likelihood of an SSO. A proactive approach that requires Enrollees to ensure a
system-wide operation, maintenance, and management plan is in place will
reduce the number and frequency of SSOs within the state. This approach will in
turn decrease the risk to human health and the environment caused by SSOs.
4. Major causes of SSOs include: grease blockages, root blockages, sewer line
flood damage, manhole structure failures, vandalism, pump station mechanical
failures, power outages, excessive storm or ground water inflow/infiltration,
debris blockages, sanitary sewer system age and construction material failures,
lack of proper operation and maintenance, insufficient capacity and contractor-
caused damages. Many SSOs are preventable with adequate and appropriate
facilities, source control measures and operation and maintenance of the sanitary
sewer system.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 2 of 20
Statewide General WDR For Wastewater Collection Agencies 512106
SEWER SYSTEM MANAGEMENT PLANS
5. To facilitate proper funding and management of sanitary sewer systems, each
Enrollee must develop and implement a system-specific Sewer System
Management Plan (SSMP). To be effective, SSMPs must include provisions to
provide proper and efficient management, operation, and maintenance of
sanitary sewer systems, while taking into consideration risk management and
cost benefit analysis. Additionally, an SSMP must contain a spill response plan
that establishes standard procedures for immediate response to an SSO in a
manner designed to minimize water quality impacts and potential nuisance
conditions.
6. Many local public agencies in California have already developed SSMPs and
implemented measures to reduce SSOs. These entities can build upon their
existing efforts to establish a comprehensive SSMP consistent with this Order.
Others, however, still require technical assistance and, in some cases, funding to
improve sanitary sewer system operation and maintenance in order to reduce
SSOs.
7. SSMP certification by technically qualified and experienced persons can provide
a useful and cost-effective means for ensuring that SSMPs are developed and
implemented appropriately.
8. It is the State Water Board's intent to gather additional information on the causes
and sources of SSOs to augment existing information and to determine the full
extent of SSOs and consequent public health and/or environmental impacts
occurring in the State.
9. Both uniform SSO reporting and a centralized statewide electronic database are
needed to collect information to allow the State Water Board and Regional Water
Quality Control Boards (Regional Water Boards)to effectively analyze the extent
of SSOs statewide and their potential impacts on beneficial uses and public
health. The monitoring and reporting program required by this Order and the
attached Monitoring and Reporting Program No. 2006-0003-DWQ, are necessary
to assure compliance with these waste discharge requirements (WDRs).
10.Information regarding SSOs must be provided to Regional Water Boards and
other regulatory agencies in a timely manner and be made available to the public
in a complete, concise, and timely fashion.
11.Some Regional Water Boards have issued WDRs or WDRs that serve as
National Pollution Discharge Elimination System (NPDES) permits to sanitary
sewer system owners/operators within their jurisdictions. This Order establishes
minimum requirements to prevent SSOs. Although it is the State Water Board's
intent that this Order be the primary regulatory mechanism for sanitary sewer
systems statewide, Regional Water Boards may issue more stringent or more
State Water Resources Control Board Order No. 2006-0003-DWQ Page 3 of 20
Statewide General WDR For Wastewater Collection Agencies 512106
prescriptive WDRs for sanitary sewer systems. Upon issuance or reissuance of
a Regional Water Board's WDRs for a system subject to this Order, the Regional
Water Board shall coordinate its requirements with stated requirements within
this Order, to identify requirements that are more stringent, to remove
requirements that are less stringent than this Order, and to provide consistency
in reporting.
REGULATORY CONSIDERATIONS
12. California Water Code section 13263 provides that the State Water Board may
prescribe general WDRs for a category of discharges if the State Water Board
finds or determines that:
• The discharges are produced by the same or similar operations;
• The discharges involve the same or similar types of waste;
• The discharges require the same or similar treatment standards; and
• The discharges are more appropriately regulated under general discharge
requirements than individual discharge requirements.
This Order establishes requirements for a class of operations, facilities, and
discharges that are similar throughout the state.
13.The issuance of general WDRs to the Enrollees will:
a) Reduce the administrative burden of issuing individual WDRs to each
Enrollee;
b) Provide for a unified statewide approach for the reporting and database
tracking of SSOs;
c) Establish consistent and uniform requirements for SSMP development
and implementation;
d) Provide statewide consistency in reporting; and
e) Facilitate consistent enforcement for violations.
14.The beneficial uses of surface waters that can be impaired by SSOs include, but
are not limited to, aquatic life, drinking water supply, body contact and non-
contact recreation, and aesthetics. The beneficial uses of ground water that can
be impaired include, but are not limited to, drinking water and agricultural supply.
Surface and ground waters throughout the state support these uses to varying
degrees.
15.The implementation of requirements set forth in this Order will ensure the
reasonable protection of past, present, and probable future beneficial uses of
water and the prevention of nuisance. The requirements implement the water
quality control plans (Basin Plans)for each region and take into account the
environmental characteristics of hydrographic units within the state. Additionally,
the State Water Board has considered water quality conditions that could
reasonably be achieved through the coordinated control of all factors that affect
State Water Resources Control Board Order No. 2006-0003-DWQ Page 4 of 20
Statewide General WDR For Wastewater Collection Agencies 512106
water quality in the area, costs associated with compliance with these
requirements, the need for developing housing within California, and the need to
develop and use recycled water.
16.The Federal Clean Water Act largely prohibits any discharge of pollutants from a
point source to waters of the United States except as authorized under an
NPDES permit. In general, any point source discharge of sewage effluent to
waters of the United States must comply with technology-based, secondary
treatment standards, at a minimum, and any more stringent requirements
necessary to meet applicable water quality standards and other requirements.
Hence, the unpermitted discharge of wastewater from a sanitary sewer system to
waters of the United States is illegal under the Clean Water Act. In addition,
many Basin Plans adopted by the Regional Water Boards contain discharge
prohibitions that apply to the discharge of untreated or partially treated
wastewater. Finally, the California Water Code generally prohibits the discharge
of waste to land prior to the filing of any required report of waste discharge and
the subsequent issuance of either WDRs or a waiver of WDRs.
17.California Water Code section 13263 requires a water board to, after any
necessary hearing, prescribe requirements as to the nature of any proposed
discharge, existing discharge, or material change in an existing discharge. The
requirements shall, among other things, take into consideration the need to
prevent nuisance.
18.California Water Code section 13050, subdivision (m), defines nuisance as
anything which meets all of the following requirements:
a. Is injurious to health, or is indecent or offensive to the senses, or an
obstruction to the free use of property, so as to interfere with the
comfortable enjoyment of life or property.
b. Affects at the same time an entire community or neighborhood, or any
considerable number of persons, although the extent of the annoyance or
damage inflicted upon individuals may be unequal.
c. Occurs during, or as a result of, the treatment or disposal of wastes.
19.This Order is consistent with State Water Board Resolution No. 68-16 (Statement
of Policy with Respect to Maintaining High Quality of Waters in California) in that
the Order imposes conditions to prevent impacts to water quality, does not allow
the degradation of water quality, will not unreasonably affect beneficial uses of
water, and will not result in water quality less than prescribed in State Water
Board or Regional Water Board plans and policies.
20.The action to adopt this General Order is exempt from the California
Environmental Quality Act (Public Resources Code §21000 at seq.) because it is
an action taken by a regulatory agency to assure the protection of the
environment and the regulatory process involves procedures for protection of the
environment. (Cal. Code Regs., tit. 14, §15308). In addition, the action to adopt
State Water Resources Control Board Order No. 2006-0003-DWQ Page 5 of 20
Statewide General WDR For Wastewater Collection Agencies 512106
this Order is exempt from CEQA pursuant to Cal.Code Regs., title 14, §15301 to
the extent that it applies to existing sanitary sewer collection systems that
constitute "existing facilities" as that term is used in Section 15301, and §15302,
to the extent that it results in the repair or replacement of existing systems
involving negligible or no expansion of capacity.
21.The Fact Sheet, which is incorporated by reference in the Order, contains
supplemental information that was also considered in establishing these
requirements.
22.The State Water Board has notified all affected public agencies and all known
interested persons of the intent to prescribe general WDRs that require Enrollees
to develop SSMPs and to report all SSOs.
23.The State Water Board conducted a public hearing on February 8, 2006, to
receive oral and written comments on the draft order. The State Water Board
received and considered, at its May 2, 2006, meeting, additional public
comments on substantial changes made to the proposed general WDRs
following the February 8, 2006, public hearing. The State Water Board has
considered all comments pertaining to the proposed general WDRs.
IT IS HEREBY ORDERED, that pursuant to California Water Code section 13263, the
Enrollees, their agents, successors, and assigns, in order to meet the provisions
contained in Division 7 of the California Water Code and regulations adopted
hereunder, shall comply with the following:
A. DEFINITIONS
1. Sanitary sewer overflow (SSO) - Any overflow, spill, release, discharge or
diversion of untreated or partially treated wastewater from a sanitary sewer
system. SSOs include:
(i) Overflows or releases of untreated or partially treated wastewater that
reach waters of the United States;
(ii) Overflows or releases of untreated or partially treated wastewater that do
not reach waters of the United States; and
(iii)Wastewater backups into buildings and on private property that are
caused by blockages or flow conditions within the publicly owned portion
of a sanitary sewer system.
2. Sanitary sewer system —Any system of pipes, pump stations, sewer lines, or
other conveyances, upstream of a wastewater treatment plant headworks used
to collect and convey wastewater to the publicly owned treatment facility.
Temporary storage and conveyance facilities (such as vaults, temporary piping,
construction trenches, wet wells, impoundments, tanks, etc.) are considered to
be part of the sanitary sewer system, and discharges into these temporary
storage facilities are not considered to be SSOs.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 6 of 20

from the sanitary sewer system upstream of a wastewater treatment plant
headworks.
6. Satellite collection system —The portion, if any, of a sanitary sewer system
owned or operated by a different public agency than the agency that owns and
operates the wastewater treatment facility to which the sanitary sewer system is
tributary.
7. Nuisance - California Water Code section 13050, subdivision (m), defines
nuisance as anything which meets all of the following requirements:
a. Is injurious to health, or is indecent or offensive to the senses, or an
obstruction to the free use of property, so as to interfere with the
comfortable enjoyment of life or property.
b. Affects at the same time an entire community or neighborhood, or any
considerable number of persons, although the extent of the annoyance or
damage inflicted upon individuals may be unequal.
c. Occurs during, or as a result of, the treatment or disposal of wastes.
B. APPLICATION REQUIREMENTS
1. Deadlines for Application —All public agencies that currently own or operate
sanitary sewer systems within the State of California must apply for coverage
under the general WDRs within six (6) months of the date of adoption of the
general WDRs. Additionally, public agencies that acquire or assume
responsibility for operating sanitary sewer systems after the date of adoption of
this Order must apply for coverage under the general WDRs at least three (3)
months prior to operation of those facilities.
2. Applications under the general WDRs— In order to apply for coverage pursuant
to the general WDRs, a legally authorized representative for each agency must
submit a complete application package. Within sixty (60) days of adoption of the
general WDRs, State Water Board staff will send specific instructions on how to
State Water Resources Control Board Order No. 2006-0003-DWQ Page 7 of 20
Statewide General WDR For Wastewater Collection Agencies 512106
apply for coverage under the general WDRs to all known public agencies that
own sanitary sewer systems. Agencies that do not receive notice may obtain
applications and instructions online on the Water Board's website.
3. Coverage under the general WDRs — Permit coverage will be in effect once a
complete application package has been submitted and approved by the State
Water Board's Division of Water Quality.
C. PROHIBITIONS
1. Any SSO that results in a discharge of untreated or partially treated wastewater
to waters of the United States is prohibited.
2. Any SSO that results in a discharge of untreated or partially treated wastewater
that creates a nuisance as defined in California Water Code Section 13050(m) is
prohibited.
D. PROVISIONS
1. The Enrollee must comply with all conditions of this Order. Any noncompliance
with this Order constitutes a violation of the California Water Code and is
grounds for enforcement action.
2. It is the intent of the State Water Board that sanitary sewer systems be regulated
in a manner consistent with the general WDRs. Nothing in the general WDRs
shall be:
(i) Interpreted or applied in a manner inconsistent with the Federal Clean
Water Act, or supersede a more specific or more stringent state or
federal requirement in an existing permit, regulation, or
administrative/judicial order or Consent Decree;
(ii) Interpreted or applied to authorize an SSO that is illegal under either the
Clean Water Act, an applicable Basin Plan prohibition or water quality
standard, or the California Water Code;
(iii) Interpreted or applied to prohibit a Regional Water Board from issuing an
individual NPDES permit or WDR, superseding this general WDR, for a
sanitary sewer system, authorized under the Clean Water Act or
California Water Code; or
(iv) Interpreted or applied to supersede any more specific or more stringent
WDRs or enforcement order issued by a Regional Water Board.
3. The Enrollee shall take all feasible steps to eliminate SSOs. In the event that an
SSO does occur, the Enrollee shall take all feasible steps to contain and mitigate
the impacts of an SSO.
4. In the event of an SSO, the Enrollee shall take all feasible steps to prevent
untreated or partially treated wastewater from discharging from storm drains into
State Water Resources Control Board Order No. 2006-0003-DWQ Page 8 of 20
Statewide General WDR For Wastewater Collection Agencies 512106
flood control channels or waters of the United States by blocking the storm
drainage system and by removing the wastewater from the storm drains.
5. All SSOs must be reported in accordance with Section G of the general WDRs.
6. In any enforcement action, the State and/or Regional Water Boards will consider
the appropriate factors under the duly adopted State Water Board Enforcement
Policy. And, consistent with the Enforcement Policy, the State and/or Regional
Water Boards must consider the Enrollee's efforts to contain, control, and
mitigate SSOs when considering the California Water Code Section 13327
factors. In assessing these factors, the State and/or Regional Water Boards will
also consider whether:
(I) The Enrollee has complied with the requirements of this Order, including
requirements for reporting and developing and implementing a SSMP;
(ii) The Enrollee can identify the cause or likely cause of the discharge event;
(!!!)There were no feasible alternatives to the discharge, such as temporary
storage or retention of untreated wastewater, reduction of inflow and
infiltration, use of adequate backup equipment, collecting and hauling of
untreated wastewater to a treatment facility, or an increase in the
capacity of the system as necessary to contain the design storm event
identified in the SSMP. It is inappropriate to consider the lack of feasible
alternatives, if the Enrollee does not implement a periodic or continuing
process to identify and correct problems.
(iv)The discharge was exceptional, unintentional, temporary, and caused by
factors beyond the reasonable control of the Enrollee;
(v) The discharge could have been prevented by the exercise of reasonable
control described in a certified SSMP for:
• Proper management, operation and maintenance;
• Adequate treatment facilities, sanitary sewer system facilities,
and/or components with an appropriate design capacity, to
reasonably prevent SSOs (e.g., adequately enlarging treatment or
collection facilities to accommodate growth, infiltration and inflow
(1/1), etc.);
• Preventive maintenance (including cleaning and fats, oils, and
grease (FOG) control);
• Installation of adequate backup equipment; and
• Inflow and infiltration prevention and control to the extent
practicable.
(vi)The sanitary sewer system design capacity is appropriate to reasonably
prevent SSOs.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 9 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
(vii)The Enrollee took all reasonable steps to stop and mitigate the impact of
the discharge as soon as possible.
7. When a sanitary sewer overflow occurs, the Enrollee shall take all feasible steps
and necessary remedial actions to 1) control or limit the volume of untreated or
partially treated wastewater discharged, 2)terminate the discharge, and 3)
recover as much of the wastewater discharged as possible for proper disposal,
including any wash down water.
The Enrollee shall implement all remedial actions to the extent they may be
applicable to the discharge and not inconsistent with an emergency response
plan, including the following:
(1) Interception and rerouting of untreated or partially treated wastewater
flows around the wastewater line failure;
(ii) Vacuum truck recovery of sanitary sewer overflows and wash down
water;
(ill) Cleanup of debris at the overflow site;
(iv) System modifications to prevent another SSO at the same location;
(v) Adequate sampling to determine the nature and impact of the release;
and
(vi) Adequate public notification to protect the public from exposure to the
SSO.
8. The Enrollee shall properly, manage, operate, and maintain all parts of the
sanitary sewer system owned or operated by the Enrollee, and shall ensure that
the system operators (including employees, contractors, or other agents) are
adequately trained and possess adequate knowledge, skills, and abilities.
9. The Enrollee shall allocate adequate resources for the operation, maintenance,
and repair of its sanitary sewer system, by establishing a proper rate structure,
accounting mechanisms, and auditing procedures to ensure an adequate
measure of revenues and expenditures. These procedures must be in
compliance with applicable laws and regulations and comply with generally
acceptable accounting practices.
10.The Enrollee shall provide adequate capacity to convey base flows and peak
flows, including flows related to wet weather events. Capacity shall meet or
exceed the design criteria as defined in the Enrollee's System Evaluation and
Capacity Assurance Plan for all parts of the sanitary sewer system owned or
operated by the Enrollee.
11.The Enrollee shall develop and implement a written Sewer System Management
Plan (SSMP) and make it available to the State and/or Regional Water Board
upon request. A copy of this document must be publicly available at the
Enrollee's office and/or available on the Internet. This SSMP must be approved
by the Enrollee's governing board at a public meeting.
State Water Resources Control Board Order No. 2006-0003-DWQ Page 10 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
12.In accordance with the California Business and Professions Code sections 6735,
7835, and 7835.1, all engineering and geologic evaluations and judgments shall
be performed by or under the direction of registered professionals competent and
proficient in the fields pertinent to the required activities. Specific elements of the
SSMP that require professional evaluation and judgments shall be prepared by
or under the direction of appropriately qualified professionals, and shall bear the
professional(s)' signature and stamp.
13.The mandatory elements of the SSMP are specified below. However, if the
Enrollee believes that any element of this section is not appropriate or applicable
to the Enrollee's sanitary sewer system, the SSMP program does not need to
address that element. The Enrollee must justify why that element is not
applicable. The SSMP must be approved by the deadlines listed in the SSMP
Time Schedule below.
Sewer System Management Plan (SSMP)
(1) Goal: The goal of the SSMP is to provide a plan and schedule to properly
manage, operate, and maintain all parts of the sanitary sewer system.
This will help reduce and prevent SSOs, as well as mitigate any SSOs
that do occur.
(11) Organization: The SSMP must identify:
(a) The name of the responsible or authorized representative as
described in Section J of this Order.
(b) The names and telephone numbers for management,
administrative, and maintenance positions responsible for
implementing specific measures in the SSMP program. The
SSMP must identify lines of authority through an organization chart
or similar document with a narrative explanation; and
(c) The chain of communication for reporting SSOs, from receipt of a
complaint or other information, including the person responsible for
reporting SSOs to the State and Regional Water Board and other
agencies if applicable (such as County Health Officer, County
Environmental Health Agency, Regional Water Board, and/or State
Office of Emergency Services (OES)).
(iii) Legal Authority: Each Enrollee must demonstrate, through sanitary
sewer system use ordinances, service agreements, or other legally
binding procedures, that it possesses the necessary legal authority to:
(a) Prevent illicit discharges into its sanitary sewer system
(examples may include 1/1, stormwater, chemical dumping,
unauthorized debris and cut roots, etc.);
State Water Resources Control Board Order No. 2006-0003-DWQ Page 11 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
(b) Require that sewers and connections be properly designed
and constructed;
(c) Ensure access for maintenance, inspection, or repairs for
portions of the lateral owned or maintained by the Public
Agency;
(d) Limit the discharge of fats, oils, and grease and other debris
that may cause blockages, and
(a) Enforce any violation of its sewer ordinances.
(iv) Operation and Maintenance Program. The SSMP must include those
elements listed below that are appropriate and applicable to the
Enrollee's system:
(a) Maintain an up-to-date map of the sanitary sewer system,
showing all gravity line segments and manholes, pumping
facilities, pressure pipes and valves, and applicable stormwater
conveyance facilities;
(b) Describe routine preventive operation and maintenance activities
by staff and contractors, including a system for scheduling regular
maintenance and cleaning of the sanitary sewer system with more
frequent cleaning and maintenance targeted at known problem
areas. The Preventative Maintenance (PM) program should have
a system to document scheduled and conducted activities, such
as work orders;
(c) Develop a rehabilitation and replacement plan to identify and
prioritize system deficiencies and implement short-term and long-
term rehabilitation actions to address each deficiency. The
program should include regular visual and TV inspections of
manholes and sewer pipes, and a system for ranking the
condition of sewer pipes and scheduling rehabilitation.
Rehabilitation and replacement should focus on sewer pipes that
are at risk of collapse or prone to more frequent blockages due to
pipe defects. Finally, the rehabilitation and replacement plan
should include a capital improvement plan that addresses proper
management and protection of the infrastructure assets. The plan
shall include a time schedule for implementing the short- and
long-term plans plus a schedule for developing the funds needed
for the capital improvement plan;
(d) Provide training on a regular basis for staff in sanitary sewer
system operations and maintenance, and require contractors to
be appropriately trained; and

installation of new sanitary sewer systems, pump stations and other
appurtenances; and for the rehabilitation and repair of existing
sanitary sewer systems; and
(b) Procedures and standards for inspecting and testing the installation
of new sewers, pumps, and other appurtenances and for
rehabilitation and repair projects.
(vi) Overflow Emergency Response Plan - Each Enrollee shall develop and
implement an overflow emergency response plan that identifies
measures to protect public health and the environment. At a minimum,
this plan must include the following:
(a) Proper notification procedures so that the primary responders and
regulatory agencies are informed of all SSOs in a timely manner;
(b) A program to ensure an appropriate response to all overflows;
(c) Procedures to ensure prompt notification to appropriate regulatory
agencies and other potentially affected entities (e.g. health
agencies, Regional Water Boards, water suppliers, etc.) of all SSOs
that potentially affect public health or reach the waters of the State
in accordance with the MRP. All SSOs shall be reported in
accordance with this MRP, the California Water Code, other State
Law, and other applicable Regional Water Board WDRs or NPDES
permit requirements. The SSMP should identify the officials who
will receive immediate notification;
(d) Procedures to ensure that appropriate staff and contractor
personnel are aware of and follow the Emergency Response Plan
and are appropriately trained;
(a) Procedures to address emergency operations, such as traffic and
crowd control and other necessary response activities; and
(f) A program to ensure that all reasonable steps are taken to contain
and prevent the discharge of untreated and partially treated
wastewater to waters of the United States and to minimize or
correct any adverse impact on the environment resulting from the
SSOs, including such accelerated or additional monitoring as may
be necessary to determine the nature and impact of the discharge.

Statewide General WDR For Wastewater Collection Agencies 512106
(vii) FOG Control Program: Each Enrollee shall evaluate its service area to
determine whether a FOG control program is needed. If an Enrollee
determines that a FOG program is not needed, the Enrollee must provide
justification for why it is not needed. If FOG is found to be a problem, the
Enrollee must prepare and implement a FOG source control program to
reduce the amount of these substances discharged to the sanitary sewer
system. This plan shall include the following as appropriate:
(a)An implementation plan and schedule for a public education
outreach program that promotes proper disposal of FOG;
(b)A plan and schedule for the disposal of FOG generated within the
sanitary sewer system service area. This may include a list of
acceptable disposal facilities and/or additional facilities needed to
adequately dispose of FOG generated within a sanitary sewer
system service area;
(c) The legal authority to prohibit discharges to the system and
identify measures to prevent SSOs and blockages caused by
FOG;
(d) Requirements to install grease removal devices (such as traps or
interceptors), design standards for the removal devices,
maintenance requirements, BMP requirements, record keeping
and reporting requirements;
(a)Authority to inspect grease producing facilities, enforcement
authorities, and whether the Enrollee has sufficient staff to inspect
and enforce the FOG ordinance;
(f) An identification of sanitary sewer system sections subject to
FOG blockages and establishment of a cleaning maintenance
schedule for each section; and
(g) Development and implementation of source control measures for
all sources of FOG discharged to the sanitary sewer system for
each section identified in (f) above.
(viii) System Evaluation and Capacity Assurance Plan: The Enrollee shall
prepare and implement a capital improvement plan (CIP) that will
provide hydraulic capacity of key sanitary sewer system elements for
dry weather peak flow conditions, as well as the appropriate design
storm or wet weather event. At a minimum, the plan must include:
(a) Evaluation: Actions needed to evaluate those portions of the
sanitary sewer system that are experiencing or contributing to an
SSO discharge caused by hydraulic deficiency. The evaluation
must provide estimates of peak flows (including flows from SSOs
State Water Resources Control Board Order No. 2006-0003-DWQ Page 14 of 20
Statewide General WDR For Wastewater Collection Agencies 5/2/06
that escape from the system) associated with conditions similar to
those causing overflow events, estimates of the capacity of key
system components, hydraulic deficiencies (including components
of the system with limiting capacity) and the major sources that
contribute to the peak flows associated with overflow events;
(b) Design Criteria: Where design criteria do not exist or are
deficient, undertake the evaluation identified in (a) above to
establish appropriate design criteria; and
(c) Capacity Enhancement Measures: The steps needed to
establish a short- and long-term CIP to address identified
hydraulic deficiencies, including prioritization, alternatives
analysis, and schedules. The CIP may include increases in pipe
size, 1/1 reduction programs, increases and redundancy in
pumping capacity, and storage facilities. The CIP shall include an
implementation schedule and shall identify sources of funding.
(d) Schedule: The Enrollee shall develop a schedule of completion
dates for all portions of the capital improvement program
developed in (a)-(c) above. This schedule shall be reviewed and
updated consistent with the SSMP review and update
requirements as described in Section D. 14.
(ix) Monitoring, Measurement, and Program Modifications: The Enrollee
shall:
(a) Maintain relevant information that can be used to
establish and prioritize appropriate SSMP activities;
(b) Monitor the implementation and, where appropriate,
measure the effectiveness of each element of the
SSMP;
(c) Assess the success of the preventative maintenance
program;
(d) Update program elements, as appropriate, based on
monitoring or performance evaluations; and
(a) Identify and illustrate SSO trends, including:
frequency, location, and volume.
(x) SSMP Program Audits -As part of the SSMP, the Enrollee shall
conduct periodic internal audits, appropriate to the size of the system
and the number of SSOs. At a minimum, these audits must occur every
two years and a report must be prepared and kept on file. This audit
shall focus on evaluating the effectiveness of the SSMP and the

AMENDING MONITORING AND REPORTING PROGRAM
FOR
STATEWIDE GENERAL WASTE DISCHARGE REQUIREMENTS FOR
SANITARY SEWER SYSTEMS
The State of California, Water Resources Control Board (hereafter State Water Board)finds:
1. The State Water Board is authorized to prescribe statewide general Waste Discharge
Requirements (WDRs)for categories of discharges that involve the same or similar operations
and the same or similar types of waste pursuant to Water Code section 13263(i).
2. Water Code section 13193 at seq. requires the Regional Water Quality Control Boards (Regional
Water Boards) and the State Water Board (collectively, the Water Boards)to gather Sanitary
Sewer Overflow (SSO) information and make this information available to the public, including but
not limited to, SSO cause, estimated volume, location, date,time, duration, whether or not the
SSO reached or may have reached waters of the state, response and corrective action taken, and
an enrollee's contact information for each SSO event. An enrollee is defined as the public entity
having legal authority over the operation and maintenance of, or capital improvements to, a
sanitary sewer system greater than one mile in length.
3. Water Code section 13271, at seq. requires notification to the California Office of Emergency
Services (Cal OES), formerly the California Emergency Management Agency, for certain
unauthorized discharges, including SSOs.
4. On May 2, 2006, the State Water Board adopted Order 2006-0003-DWQ, "Statewide Waste
Discharge Requirements for Sanitary Sewer Systems" (hereafter SSS WDRs) to comply with
Water Code section 13193 and to establish the framework for the statewide SSO Reduction
Program.
5. Subsection G.2 of the SSS WDRs and the Monitoring and Reporting Program (MRP) provide that
the Executive Director may modify the terms of the MRP at any time.
6. On February 20, 2008, the State Water Board Executive Director adopted a revised MRP for the
SSS WDRs to rectify early notification deficiencies and ensure that first responders are noted in
a timely manner of SSOs discharged into waters of the state.
7. When notified of an SSO that reaches a drainage channel or surface water of the state, Cal OES,
pursuant to Water Code section 13271(a)(3), forwards the SSO notification information to local
government agencies and first responders including local public health officials and the applicable
Regional Water Board. Receipt of notifications for a single SSO event from both the SSO reporter

and Cal DES is duplicative. To address this, the SSO notification requirements added by the
February 20, 2008 MRP revision are being removed in this MRP revision.
8. In the February 28, 2008 Memorandum of Agreement between the State Water Board and the
California Water and Environment Association (CWE4), the State Water Board committed to re-
designing the CIWQS'Online SSO Database to allow"event" based SSO reporting versus the
original "location" based reporting. Revisions to this MRP and accompanying changes to the
CIWQS Online SSO Database will implement this change by allowing for multiple SSO
appearance points to be associated with each SSO event caused by a single asset failure.
9. Based on stakeholder input and Water Board staff experience implementing the SSO Reduction
Program, SSO categories have been revised in this MRP. In the prior version of the MRP, SSOs
have been categorized as Category 1 or Category 2. This MRP implements changes to $SO
categories by adding a Category 3 SSO type. This change will improve data management to
further assist Water Board staff with evaluation of high threat and low threat SSOs by placing
them in unique categories (i.e., Category 1 and Category 3, respectively). This change will also
assist enrollees in identifying SSOs that require Cal OES notification.
10. Based on over six years of implementation of the SSS WDRs, the State Water Board concludes
that the February 20, 2008 MRP must be updated to better advance the SSO Reduction Program°
objectives, assess compliance, and enforce the requirements of the SSS WDRs.
IT IS HEREBY ORDERED THAT:
Pursuant to the authority delegated by Water Code section 13267(f), Resolution 2002-0104, and
Order 2006-0003-DWQ, the MRP for the SSS WDRs (Order 2006-0003-DWQ) is hereby amended

possible, but not later than two (2) hours after(A)the enrollee has knowledge of the
discharge, (B) notification is possible, and (C) notification can be provided without
substantially impeding cleanup or other emergency measures, notify the Cal DES and obtain
a notification control number.
2. To satisfy notification requirements for each applicable SSO, the enrollee shall provide the
information requested by Cal DES before receiving a control number. Spill information
requested by Cal DES may include:

SSO report in the CIWQS Online SSO Database, the enrollee shall provide updates to Cal
DES regarding substantial changes to the estimated volume of untreated or partially treated
sewage discharged and any substantial change(s)to known impact(s).
4. PLSDs: The enrollee is strongly encouraged to notify Cal DES of discharges greater than or
equal to 1,000 gallons of untreated or partially treated wastewater that result or may result in
a discharge to surface water resulting from failures or flow conditions within a privately owned
sewer lateral or from other private sewer asset(s) if the enrollee becomes aware of the PLSD.

resulting from an enrollee's sanitary sewer system failure or flow condition that:
a. Reach surface water and/or reach a drainage channel tributary to a surface water; or
b. Reach a MS4 and are not fully captured and returned to the sanitary sewer system or
not otherwise captured and disposed of properly. Any volume of wastewater not
recovered from the MS4 is considered to have reached surface water unless the
storm drain system discharges to a dedicated storm water or groundwater infiltration
basin (e.g., infiltration pit, percolation pond).
ii. Category 2— Discharges of untreated or partially treated wastewater greater than or
equal to 1,000 gallons resulting from an enrollee's sanitary sewer system failure or flow
condition that does not reach a surface water, a drainage channel, or the MS4 unless the
entire SSO volume discharged to the storm drain system is fully recovered and disposed
of properly.
iii. Category 3—All other discharges of untreated or partially treated wastewater resulting
from an enrollee's sanitary sewer system failure or flow condition.
4. Sanitary Sewer Overflow Reporting to CIWQS -Timeframes

ADOPTING FATS, OILS AND GREASE CONTROL REGULATIONS
APPLICABLE TO FOOD SERVICE ESTABLISHMENTS
AN ORDINANCE OF THE BOARD OF DIRECTORS OF ORANGE
COUNTY SANITATION DISTRICT ADOPTING FATS, OILS AND
GREASE CONTROL REGULATIONS APPLICABLE TO FOOD SERVICE
ESTABLISHMENTS
WHEREAS, pursuant to the County Sanitation District Act, Health & Safety Code
§§4700 at seq., the Orange County Sanitation District ("District") has the authority to
adopt ordinances relating to the provision of sewer services and facilities, and
regulations of those services and facilities; and
WHEREAS, the Regional Water Quality Control Board ('RWQCB") for the Santa
Ana Region adopted Order R8-2002-0014, which prescribes general waste discharge
requirements prohibiting sanitary sewer overflows ("SSOs") by sewer collection
agencies; and
WHEREAS, in Order R8-2002-0014, the RWQCB found that one of the leading
causes of SSOs within the Santa Ana Region, which encompasses the District's service
area is"grease blockages;"and
WHEREAS, SSOs often caused by discharge of wastewater containing high
levels of fat, oils and grease ('FOG"), suspended solids, pathogenic organisms, and
other pollutants, may cause temporary exceedances of applicable water quality
objectives, pose a threat to the public health, adversely affect aquatic life, and impair the
public recreational use and aesthetic enjoyment of surface waters within the District's
service area; and
WHEREAS, the 2000-2001 Orange County Grand Jury ("Grand Jury") conducted
a survey among 35 wastewater collection and treatment agencies in Orange County and
concluded that one of the leading causes of SSOs and sewage spills is sewer lines
clogged from the accumulation of FOG discharged from Food Service Establishments;
and
WHEREAS, the Grand Jury further concluded that more effective methods of
minimizing grease discharges into the sewer system must be developed and
implemented to reduce the discharge of FOG to the sewer system in order to prevent
sewer blockages and SSOs; and
WHEREAS, Order No. R8-2002-0014 requires the District to monitor and control
SSOs and to develop a FOG Control Program by December 30. 2004; and
w -oxspi:NMs :ro/n/a 2
WHEREAS, in light of the overwhelming evidence that FOG is a primary cause of
SSOs, the District desires to implement a FOG Control Program to prevent SSOs; and
WHEREAS, Section 1014 of the 2001 California Plumbing Code, applicable to all
occupancies in the State pursuant to the California Building Standards Law, requires the
installation of grease traps or interceptors when in the opinion of the Building Official
waste pretreatment is required; and
WHEREAS, the foregoing findings indicate that a FOG Control Program is
required for Food Service Establishments within the District's jurisdiction to comply with
waste discharge regulations and prevent the harmful effects of SSOs; and
WHEREAS, the regulations adopted herein will require existing Food Service
Establishments to install grease control devices or interceptors no later than three years
from the effective date of this Ordinance, and the Board finds that three years is a
reasonable amortization period for existing Food Service Establishments that are
operating without a grease control device or grease interceptor, and
WHEREAS, the Board of Directors finds that specific enforcement provisions
must be adopted to govern discharges of wastewater to the District's system by Food
Service Establishments.
NOW, THEREFORE, the Board of Directors does hereby ordain as follows:

service, or vice versa, is prohibited-
G. Discharge of any waste including FOG and solid materials removed from
the grease control device to the sewer system is prohibited. Grease
removed from grease interceptors shall be wastehauled periodically as
part of the operation and maintenance requirements for grease
interceptors.
cases-oxsA:xisnu:to/Z2/a+ 12
H. Operation of grease interceptors with FOG and solids accumulation
exceeding 25% of the design hydraulic depth of the grease interceptor
(25% Rule)
2.3 FOG WASTEWATER DISCHARGE PERMIT REQUIRED
No person shall discharge, or cause to be discharged any wastewater from Food
Service Establishments directly or indirectly into the sewer system without first
obtaining a FOG Wastewater Discharge Permit pursuant to this Ordinance.
2.4 BEST MANAGEMENT PRACTICES REQUIRED
All Food Services Establishments shall implement Best Management Practices in
its operation to minimize the discharge of FOG to the sewer system. Detailed
requirements for Best Management Practices shall be specified in the permit.
This may include kitchen practices and employee training that are essential in
minimizing FOG discharge.
2.5 FOG PRETREATMENT REQUIRED
Food Service Establishments are required to install, operate and maintain an
approved type and adequately sized grease interceptor necessary to maintain
compliance with the objectives of this Ordinance, subject to the variance and
waiver provisions of Section 2.6. The grease interceptor shall be adequate to
separate and remove FOG contained in wastewater discharges from Food
Service Establishments prior to discharge to the sewer system. Fixtures,
equipment, and drain lines located in the food preparation and clean up areas of
Food Service Establishments that are sources of FOG discharges shall be
connected to the grease interceptor. Compliance shall be established as follows:
A. New Construction of Food Service Establishments
New construction of Food Service Establishments shall include and install
grease interceptors prior to commencing discharges of wastewater to the
sewer system.
B. Existing Food Service Establishments
i. For existing Food Service Establishments, the requirement to
install and to properly operate and maintain a grease interceptor
may be conditionally stayed, that is, delayed in its implementation
by the FOG Control Program Manager for a maximum period of
three years from the effective date of this Ordinance (3-year
Amortization Period). Terms and conditions for application of a
stay to a Food Service Establishment shall be set forth in the
permit. The Board finds that three years is a reasonable
amortization period for existing Food Service Establishments that
are operating without a grease interceptor.
wsmS-OxspjCM45ilU/22/ur 13
2. Existing Food Service Establishments, which have caused or
contributed to grease-related blockage in the sewer system, or
which have sewer laterals connected to hot spots, or which have
been determined to contribute significant FOG to the sewer
system by the FOG Control Program Manager based on
inspection or sampling, shall be deemed to have reasonable
potential to adversely impact the sewer system, and shall install
grease interceptors within 180 days upon notification by the
District.
3. Existing Food Service Establishments or Food Service
Establishments that change ownership, that undergo remodeling
or a change in operations as defined in Section 1.2 of this
Ordinance, shall be required to install a grease interceptor.
2.6 VARIANCE AND WAIVER OF GREASE INTERCEPTOR REQUIREMENT
A. Variance from Grease Interceptor Requirements
An existing Food Service Establishment may obtain a variance from the
grease interceptor requirement to allow alternative pretreatment
technology that is, at least, equally effective in controlling the FOG
discharge in lieu of a grease interceptor, if the Food Service
Establishment demonstrates that it is impossible or impracticable to
install, operate or maintain a grease interceptor. The FOG Control
Program Manager's determination to grant a variance will be based upon,
but not limited to, evaluation of the following conditions:
1. There is no adequate space for installation and/or maintenance of
a grease interceptor.
2. There is no adequate slope for gravity flow between kitchen
plumbing fixtures and the grease interceptor and/or between the
grease interceptor and the private collection lines or the public
sewer.
3. The Food Service Establishment can justify that the alternative
pretreatment technology is equivalent or better than a grease
interceptor in controlling its FOG discharge. In addition, the Food
Service Establishment must be able to demonstrate, after
installation of the proposed alternative pretreatment, its
effectiveness to control FOG discharge through downstream
visual monitoring of the sewer system,for at least three months, at
its own expense. A Variance may be granted if the results show
no visible accumulation of FOG in its lateral and/or tributary
downstream sewer lines.
B. Conditional Waiver from Installation of Grease Interceptor
An existing Food Service Establishment may obtain a conditional waiver
from installation of a grease interceptor, if the Food Service
cases-0xs:pj:n19n4510/22/w 14
Establishment demonstrates that it has negligible FOG discharge and
insignificant impact to the sewer system. Although a waiver from
installation of grease interceptor may be granted, the Food Service
Establishment may be required to provide space and plumbing
segregation for future installation of grease interceptor. The FOG Control
Program Managers determination to grant or revoke a conditional waiver
shall be based upon, but not limited to, evaluation of the following
conditions:
1. Quantity of FOG discharge as measured or as indicated by the
size of Food Service Establishment based on seating capacity,
number of meals served, menu, water usage, amount of on-site
consumption of prepared food and other conditions that may
reasonably be shown to contribute to FOG discharges.
2. Adequacy of implementation of Best Management Practices and
compliance history.
3. Sewer size, grade, condition based on visual information, FOG
deposition in the sewer by the Food Service Establishment, and
history of maintenance and sewage spills in the receiving sewer
system.
4. Changes in operations that significantly affect FOG discharge.
5. Any other condition deemed reasonably related to the generation
of FOG discharges by the FOG Control Program Manager.
C. Waiver from Grease Interceptor Installation with a Grease Disposal
Mitigation Fee
For Food Service Establishments where the installation of grease
interceptor is not feasible and no equivalent alternative pretreatment can
be installed, a waiver from the grease interceptor requirement may be
granted with the imposition of a Grease Disposal Mitigation Fee as
described in Section 2.8. Additional requirements may be imposed to
mitigate the discharge of FOG into the sewer system. The FOG Control
Program Manager's determination to grant the waiver with a Grease
Disposal Mitigation Fee will be based upon, but not limited to, evaluation
of the following conditions:
1. There is no adequate space for installation and/or maintenance of
a grease interceptor.
2. There is no adequate slope for gravity flow between kitchen
plumbing fixtures and the grease interceptor and/or between the
grease interceptor and the private collection lines or the public
sewer.
3. A variance from grease interceptor installation to allow altemative
pretreatment technology cannot be granted.
cases-oxsrj:#1 M45:10/U/04 15
D. Application for Waiver or Variance of Requirement for Grease Interceptor
A Food Service Establishment may submit an application for waiver or
variance from the grease interceptor requirement to the FOG Control
Program Manager. The Food Service Establishment bears the burden of
demonstrating, to the FOG Control Program Manager's reasonable
satisfaction, that the installation of a grease interceptor is not feasible or
applicable. Upon determination by the FOG Control Program Manager
that reasons are sufficient to justify a variance or waiver, the permit will be
issued or revised to include the variance or waiver and relieve the Food
Service Establishment from the requirement.
E. Terms and conditions
A variance or waiver shall contain terms and conditions that serve as
basis for its issuance. A waiver or variance may be revoked at any time
when any of the terms and conditions for its issuance is not satisfied or if
the conditions upon which the waiver was based change so that the
justification for the waiver no longer exists. The waiver or variance shall
be valid so long as the Food Service Establishment remains in
compliance with their terms and conditions until the expiration date
specified in the variance or waiver.
2.7 COMMERCIAL PROPERTIES
Property owners of commercial properties or their official designee(s) shall be
responsible for the installation and maintenance of the grease interceptor serving
multiple Food Service Establishments that are located on a single parcel.
2.8 GREASE DISPOSAL MITIGATION FEE
Food Service Establishments that operate without a grease control interceptor
may be required to pay an annual Grease Disposal Mitigation Fee to equitably
cover the costs of increased maintenance of the sewer system as a result of the
Food Service Establishments' inability to adequately remove FOG from its
wastewater discharge. This Section shall not be interpreted to allow the new
construction of, or existing Food Service Establishments undergoing remodeling
or change in operations to operate without an approved grease interceptor
unless the District has determined that it is impossible or impracticable to install
or operate a grease control interceptor for the subject facility under the provisions
of Section 2.6 of this Ordinance.
A. The Grease Disposal Mitigation Fee shall be established by ordinance or
resolution of the Board of Directors, and shall be based on the estimated
annual increased cost of maintaining the sewer system for inspection and
removal of FOG and other viscous or solidifying agents attributable to the
Food Service Establishment resulting from the lack of a grease
interceptor or grease control device.
vests-oxs:P:rrsWa :10/=/oa 16
B. The Grease Disposal Mitigation Fee may be waived or reduced on a no
less than an annual basis when the discharger demonstrates to the
reasonable satisfaction of the FOG Control Program Manager that they
had used best management and waste minimization practices on a
regular basis that has significantly reduced the introduction of FOG into
the sewer system.
C. The Grease Disposal Mitigation Fee may not be waived or reduced when
the Food Service Establishment does not comply with the minimum
requirements of this Ordinance and/or its discharge into the sewer system
in the preceding 12 months has caused or potentially caused or
contributed alone or collectively, in sewer blockage or SSO in the sewer
downstream, or surrounding the Food Service Establishment prior to the
waiver request.
2.9 SEWER SYSTEM OVERFLOWS, PUBLIC NUISANCE,ABATEMENT ORDERS
AND CLEANUP COSTS
Notwithstanding the three-year amortization period established in Section 2.5,
Food Service Establishments found to have contributed to a sewer blockage,
SSOs or any sewer system interferences resulting from the discharge of
wastewater or waste containing FOG, shall be ordered to install and maintain a
grease interceptor, and may be subject to a plan to abate the nuisance and
prevent any future health hazards created by sewer line failures and blockages,
SSOs or any other sewer system interferences. SSOs may cause threat and
injury to public health, safety, and welfare of life and property and are hereby
declared public nuisances. Furthermore, sewer lateral failures and SSOs caused
by Food Service Establishments alone or collectively, are the responsibility of the
private property owner or Food Service Establishment, and individual(s) as a
responsible officer or owner of the Food Service Establishment. If the District
must act immediately to contain and clean up an SSO caused by blockage of a
private or public sewer lateral or system serving a Food Service Establishment ,
or at the request of the property owner or operator of the Food Service
Establishment, or because of the failure of the property owner or Food Service
Establishment to abate the condition causing immediate threat of injury to the
health, safety, welfare, or property of the public, the District's costs for such
abatement may be entirely borne by the property owner or operator of the Food
Service Establishment, and individual(s) as a responsible officer or owner of the
Food Service Establishment(s) and may constitute a debt to the District and
become due and payable upon the District's request for reimbursement of such
costs.

Act (33 U.S.C. 1251, et sec.), the General Pretreatment Regulations (40
CFR 403), and the Porter-Cologne Water Quality Control Act (Water Code
Sections 13000, at seq.), to implement and enforce a program for the
regulation of Wastewater discharges to OCSD's sewers; and
B. That OCSD is required by federal, state, and local law to meet applicable
standards of treatment plant effluent quality; and
C. Thatthe adoption of this Ordinance is statutorily exempt under the California
Environmental Quality Act pursuant to the provisions of Public Resources
Code Section 21080(b)(8) and California Code of Regulations Section
15273(a) and categorically exempt pursuant to California Code of
Regulations Sections 15307 and 15308.
NOW,THEREFORE, the Board of Directors of the Orange County Sanitation District does
ORDAIN:
Section I: Wastewater Discharge Regulations governing the use of OCSD's Sewerage
Facilities are hereby restated and amended to provide as follows:
ARTICLE 1. GENERAL PROVISIONS
101. PURPOSE AND POLICY
This ordinance sets uniform requirements for Users of OCSD's Sewerage Facilities and
enables OCSD to comply with all applicable state and federal laws, including the Clean
Water Act (33 United States Code [U.S.C.] section 1251, et seq.) and the General
Pretreatment Regulations (Title 40 of the Code of Federal Regulations [CFR] Part 403).
This Ordinance shall be interpreted in accordance with the definitions set forth in Section
102. The provisions of the Ordinance shall apply to the direct or indirect discharge of all
liquid wastes carried to facilities of OCSD.
A. The purpose of this Ordinance is to provide for the maximum public benefit
from the use of OCSD's Sewerage Facilities. This shall be accomplished
by regulating sewer use and Wastewater discharges; by providing equitable
distribution of costs, in compliance with applicable federal, state, and local
regulations; and by supporting the proper disposal of Prescription Drugs as
noted in the guidelines published by the Office of National Drug Control
Policy. The revenues to be derived from the application of this Ordinance
shall be used to defray all costs of providing sewerage service by OCSD,
including, but not limited to, administration, operation, monitoring,
OCSD-48-5
maintenance, financing, capital construction, replacement and recovery,
and provisions for necessary reserves;
B. This ordinance is meant to protect both OCSD personnel who may be
affected by Wastewater, sludge, and biosolids in the course of their
employment and the general public.
C. To comply with federal, state, and local policies and to allow OCSD to meet
applicable standards of treatment plant effluent quality, biosolids quality,
and air quality, provisions are made in this Ordinance for the regulation of
Wastewater discharges to the public sewer. This Ordinance establishes
quantity and quality limits on all Wastewater discharges which may
adversely affect OCSD's Sewerage System, processes, effluent quality,
biosolids quality, air emission characteristics, or inhibit OCSD's ability to
beneficially reuse or dispose of its treated Wastewater, biosolids or meet
biosolids discharge criteria.
D. It is the intent of these limits to improve the quality of Wastewater being
received for treatment and to encourage water conservation and
Wastewater minimization by all Users connected to a public sewer. This
Ordinance also provides for regulation of the degree of Wastewater
Pretreatment required, the issuance of permits for Wastewater discharge
and connections and other miscellaneous permits, and establishes
penalties for violation of the Ordinance.
E. OCSD is committed to: 1) a policy of Wastewater reclamation and reuse to
provide alternate sources of water supply for OCSD and agencies with
which OCSD has agreements for Wastewater reclamation; and 2) a policy
for the protection of groundwater. OCSD is also committed to help protect
groundwater goals as established by various water quality and water
purveyor agencies. To fulfill these commitments, OCSD may implement
more stringent quality requirements on Wastewater discharges through
regulation, including revisions to this Ordinance.
F. OCSD is committed to a policy for the beneficial use of biosolids, the
implementation of programs to land-apply or provide for the marketing and
distribution of biosolids, which may necessitate more stringent quality
requirements on Wastewater discharges.
G. OCSD is also committed to meet applicable air quality goals established by
the South Coast Air Quality Management District, which may further
necessitate more stringent quality requirements on Wastewater discharges.

service from OCSD pays its reasonably proportionate share of all the costs
of providing that sewerage service. Charges for use to recover the cost of
conveying, treating, and disposing of Sewage in OCSD's Sewerage
Facilities are exclusive of any fees levied by local sewering agencies. The
charge for use shall be based on the total maintenance, operation, capital
expenditures, and reserve requirements for providing Wastewater
collection, treatment, and disposal.
B. A Discharger who is issued a Class I Wastewater Discharge Permit under
the provisions of this Ordinance shall pay a charge for use in accordance
with the formula contained herein and the unit charge rates adopted by
Ordinance of the Board of Directors. These fees shall be invoiced on a
quarterly basis. The quarterly invoice shall be based upon an estimate of
the annual use as determined by OCSD. OCSD shall compute the charge
for use based upon actual use for the preceding fiscal year on an annual
reconciliation statement.
C. The charge for use is payable within forty-five (45) days of invoicing by
OCSD. A special assessment credit will be allowed for any regional sanitary
sewer service charge adopted by the Board of Directors by separate

D. In order for OCSD to determine actual annual water use, the User shall
provide to OCSD copies of its water bills. If these water bill copies are not
OCSD-48-38
received by August 15th of each year for the 12 month period ended closest
to June 30, OCSD will endeavor to obtain the water use data. Data obtained
by OCSD will be considered correct and will not be adjusted before the next
annual reconciliation statement. There shall be a fee levied for OCSD
administrative costs when OCSD obtains water use data. OCSD's Board
of Directors shall adopt the amount of the fee.
E. The charge for use shall be computed by the following formula:
Charge for Use = VoV + BoB + SoS —Special Assessment Credit
Where V = total annual volume of flow, in millions of gallons
B = total annual discharge of biochemical oxygen demand, in thousands of
pounds
S = total annual discharge of suspended solids, in thousands of pounds
Vo, Bo, So = Unit Charge rates established and adopted by Ordinance of
OCSD's Board of Directors, based upon the funding requirements of
providing sewerage service, in dollars per unit as described in Paragraph F
below:
F. The Unit Charge rates in the charge-for-use formula shall be determined by
the following method:
1. An Operations and Maintenance component of the Unit Charge for
the total annual operation and maintenance funding requirements of
the Sewerage System shall be levied at a rate to be determined from
time to time by the Board of Directors. This Charge shall be allocated
among the three Wastewater charge parameters of flow, biochemical
oxygen demand and suspended solids in accordance with the
General Manager's determination as to the costs associated with
each parameter and pursuant to applicable requirements of state
and federal Regulatory Agencies.
The operation and maintenance costs as distributed to flow,
biochemical oxygen demand and suspended solids shall be divided
by the projected annual total flow volume and weights of biochemical
oxygen demand and suspended solids to be treated by the
Sewerage System in the budgeted year.
2. A Capital Facilities Replacement Service component of the Unit
Charge for capital replacement and capital improvement shall be
levied at a rate to be determined from time to time by the Board of
Directors. This charge shall be allocated among Wastewater charge
OCSD-48-39
parameters of flow, biochemical oxygen demand, and suspended
solids in accordance with the General Manager's determination of
which portion of the charge predominantly relates to each parameter.
The capital facilities charge distributed to biochemical oxygen
demand, and suspended solids shall be divided by the projected
annual weights of biochemical oxygen demand and suspended
solids to be treated by the Sewerage System in the budgeted year.
3. The Unit Charge rates for each respective Wastewater component
in (1) and (2) above shall be summed. The Unit Charge rates so
determined will be expressed in dollars per million gallons for Vo, and
in dollars per thousand pounds for Bo and So.
G. Other measurements of the organic content of the Wastewater of a
Discharger, such as COD or TOC, may be used instead of BOD. However,
the Discharger must establish to the General Manager's satisfaction a
relationship between the BOD of the Wastewater and the parameter of
measure. This relationship shall be used by OCSD in determining the
charge for use.
When Wastewater from sanitary facilities is discharged separately from the
other Wastewater of a Discharger, the charge for use for discharging the
Wastewater may be determined by using the following:
1. 25 gallons per employee per eight-hour working day.
2. BOD and suspended solids to be calculated at domestic Wastewater
strength per employee per year.
The number of employees will be considered as the average number of
people employed full time on a daily basis. This may be determined by
averaging the number of people employed at the beginning and end of each
quarter, or other period that reflects normal employment fluctuations.

regulated process if no Pretreatment exists. If
other Wastewaters are mixed with the regulated
Wastewater prior to Pretreatment the User
should measure the flows and concentrations
necessary to allow use of the Combined
Wastestream Formula in 40 CFR 403.6(e) to
evaluate compliance with the Pretreatment
Standards. Where an alternate concentration or
mass limit has been calculated in accordance
with 40 CFR 403.6(e) this adjusted limit along
with supporting data shall be submitted to
OCSD;
d) Sampling and analysis shall be performed in
accordance with this Ordinance;
e) The General Manager may allow the
submission of a baseline report which utilizes
only historical data so long as the data provides

steps being taken by the User to return to the established
schedule; and
d) In no event shall more than nine (9) months elapse between
such progress reports to the General Manager.
3. 90-Day Compliance Reports.
Within ninety (90) days following the date for final compliance with
applicable categorical Pretreatment Standards, or in the case of a
OCSD-48-63
New Source following commencement of the introduction of
Wastewater into OCSD, any User subject to such Pretreatment
Standards and Pretreatment Requirements shall submit to the
General Manager a report containing the information described in
this Ordinance. For Users subject to equivalent mass or
concentration limits, this report shall contain a reasonable measure
of the User's long-term production rate. For all other Users subject
to categorical Pretreatment Standards expressed in terms of
allowable Pollutant discharge per unit of production (or other
measure of operation), this report shall include the User's actual
production during the appropriate sampling period. All compliance
reports must be signed and certified in accordance with this
Ordinance. All sampling will be done in conformance with Section
602.
4. Periodic Compliance Reports.
a) Except as otherwise specified in this Ordinance, all Significant
Industrial Users must, at a frequency determined by the
General Manager, submit no less than twice per year on dates
specified by OCSD reports indicating the nature,
concentration of Pollutants in the discharge which are limited
by Pretreatment Standards and the measured or estimated
average and maximum daily flows for the reporting period. In
cases where the Pretreatment Standard requires compliance
with a Best Management Practice (BMP) or pollution
prevention alternative, the User must submit documentation
required by the General Manager or the Pretreatment
Standard necessary to determine the compliance status of the
User including documentation associated with Best
Management Practices.
b) OCSD will meet reporting requirements as specified by 40
CFR Part 3 (Cross-Media Electronic Reporting). Therefore,
Users that send electronic (digital) documents to OCSD to
satisfy the requirements of this Section must register for the
system online and submit a signed Subscriber Agreement to
OCSD for review and approval.
5. Notification of the Discharge of Hazardous Waste.
a) Any User who commences the discharge of hazardous waste
shall notify OCSD, the EPA Regional Waste Management
Division Director, and state hazardous waste authorities, in
writing, of any discharge into OCSD of a substance which, if
otherwise disposed of, would be a hazardous waste under 40
OCSD-48-64
CFR Part 261. The User shall receive written approval from
the OCSD to discharge hazardous waste. Such notification
must include the name of the hazardous waste as set forth in
40 CFR Part 261, the EPA hazardous waste number, and the
type of discharge (continuous, batch, or other). If the User
discharges more than one hundred (100) kilograms of such
waste per calendar month to OCSD, the notification also shall
contain the following information to the extent such
information is known and readily available to the User: an
identification of the hazardous constituents contained in the
wastes, an estimation of the mass and concentration of such
constituents in the wastestream discharged during that
calendar month, and an estimation of the mass of constituents
in the wastestream expected to be discharged during the
following twelve (12) months. All notifications must take place
no later than one hundred and eighty (180) days after the
discharge commences. Any notification under this paragraph
need be submitted only once for each hazardous waste
discharged. However, notifications of changed conditions
must be submitted under subdivision 6 below. The notification
requirement in this Section does not apply to Pollutants
already reported by Users subject to categorical Pretreatment
Standards under the self-monitoring requirements of this
Ordinance.
b) Dischargers are exempt from the requirements of paragraph
(a), above, during a calendar month in which they discharge
no more than fifteen (15) kilograms of hazardous wastes,
unless the wastes are acute hazardous wastes as specified in
40 CFR 261.30(d) and 261.33(e). Discharge of more than
fifteen (15) kilograms of non-acute hazardous wastes in a
calendar month, or of any quantity of acute hazardous wastes
as specified in 40 CFR 261.30(d) and 261.33(e), requires a
one-time notification. Subsequent months during which the
User discharges more than such quantities of any hazardous
waste do not require additional notification.
c) In the case of any new regulations under section 3001 of
RCRA identifying additional characteristics of hazardous
waste or listing any additional substance as a hazardous
waste, the User must notify the General Manager, the EPA
Regional Waste Management Waste Division Director, and
state hazardous waste authorities of the discharge of such
substance within ninety (90)days of the effective date of such
regulations.
OCSD-48-65
d) In the case of any notification made under this Section, the
User shall certify that it has a program in place to reduce the
volume and toxicity of hazardous wastes generated to the
degree it has determined to be economically practical.
e) This provision does not create a right to discharge any
substance not otherwise permitted to be discharged by this
Ordinance, a permit issued thereunder, or any applicable
federal or state law.
6. Reports of Changed Conditions
Each User must notify the General Manager of any significant
changes to the User's operations or system which might alter the
nature, quality, or volume of its Wastewater in advance of the
change. The notification must be made promptly, but normally within
30 days. In certain cases, this period may be longer.
a) The General Manager may require the User to submit such
information as may be deemed necessary to evaluate the
changed condition, including the submission of a Wastewater
discharge permit application under this Ordinance.
b) The General Manager may issue a Wastewater discharge
permit under this Ordinance or modify an existing Wastewater
discharge permit under this ordinance in response to changed
conditions or anticipated changed conditions.
7. Reports of Potential Problems
a) In the case of any discharge, including, but not limited to,
accidental discharges, discharges of a non-routine, episodic
nature, a non-customary batch discharge, a Slug Discharge
or Slug Load, that might cause potential problems for OCSD,
the User shall follow the notification procedures under
Notification of Spill or Slug Loading in Article 5. This
notification shall also include the location of the discharge,
type of Wastewater, concentration and volume, if known, and
corrective actions taken by the User.
b) Within five (5) days following such discharge, the User shall,
unless waived by the General Manager, submit a detailed
written report. This written notification shall include, but not be
limited to, the date of the incident, the reasons for the
discharge or spill, what steps were taken to immediately
OCSD-48-66
correct the problem, and what steps are being taken to
prevent the problem from recurring.
c) Such notification shall not relieve the User of any expense,
loss, damage, or other liability which might be incurred as a
result of damage or loss to OCSD, natural resources, or any
other damage to person or property; nor shall such notification
relieve the User of any fees, fines, penalties, or other liability
which may be imposed pursuant to this Ordinance or other
applicable law.
d) A notice shall be permanently posted on the User's bulletin
board or other prominent place advising employees who to
call in the event of a discharge described in paragraph a,
above. Employers shall ensure that all employees, who could
cause such a discharge to occur, are advised of the
emergency notification procedure.
e) Significant Industrial Users are required to notify the General
Manager immediately of any changes at its facility affecting
the potential for a Slug Discharge.
8. Reports from Unpermitted Users
All Users not required to obtain a Wastewater discharge permit shall
provide appropriate reports to the General Manager as the General
Manager may require.
9. Notice of Violation/Repeat Sampling and Reporting
If sampling performed by a User indicates a violation, the User must
notify the General Manager within twenty-four (24) hours of
becoming aware of the violation. The User shall also repeat the
sampling and analysis and submit the results of the repeat analysis
to the General Manager within thirty (30)days after becoming aware
of the violation. Resampling by the User is not required if OCSD
performs sampling at the User's facility at least once a month, or if
OCSD performs sampling at the User's facility between the time
when the initial sampling was conducted and the time when the User
or OCSD receives the results of this sampling, or if OCSD has
performed the sampling and analysis in lieu of the User.
10. Other reports as required by OCSD.
a) Monitoring reports of the analyses of Wastewater constituents
and characteristics shall be in a manner and form approved
OCSD-48-67
by OCSD and shall be submitted upon request of OCSD.
When applicable, the self-monitoring requirement and
frequency of reporting may be set forth in the User's permit as
directed by OCSD. The analyses of Wastewater constituents
and characteristics and the preparation of the monitoring
report shall be done at the sole expense of the User.
b) Failure by the User to perform any required monitoring, or to
submit monitoring reports required by OCSD constitutes a
violation of this Ordinance, may result in determining whether
the Permittee is in significant non-compliance, and be cause
for OCSD to initiate all necessary tasks and analyses to
determine the Wastewater constituents and characteristics for
compliance with any limits and requirements specified in the
User's permit or in this Ordinance. The User shall be
responsible for any and all expenses of OCSD in undertaking
such monitoring analyses and preparation of reports.
501.1 Inspection and Samoling Conditions
A. OCSD may inspect and sample the Wastewater generating and disposal
facilities of any User to ascertain whether the intent of this Ordinance is
being met and the User is complying with all requirements.
B. OCSD shall have the right to place on the User's property or other locations
as determined by OCSD, such devices as are necessary to conduct
sampling or metering operations. Other sampling locations may include
downstream manholes, usually in the Sewerage System,for the purpose of
determining the compliance status of an industrial or commercial
Discharger.
C. OCSD may require the User to install and maintain sample points in areas
acceptable to OCSD outside the User's facility, within the reasonable
control of the User or OCSD. OCSD may also require lockable sample
boxes fully containing the sample points. The User shall grant OCSD
access to the sample points and sample boxes in accordance with this
Ordinance.
D. In order for OCSD to determine the Wastewater characteristics of the
Discharger for purposes of determining the annual use charge and for
compliance with permit requirements, the User shall make available for
inspection and copying by OCSD all notices, self-monitoring reports,
Waste-Tracking Forms, and records including, but not limited to, those
related to production, Wastewater generation, Wastewater disposal, and
those required in the Pretreatment Requirements without restriction but
OCSD-48-68
subject to the confidentiality provision set forth in Section 103 herein. All
such records shall be kept by the User a minimum of three (3) years.
E. If a Discharger falsifies, tampers with, or knowingly renders inaccurate any
monitoring device or sample collection method, the Discharger may be
subject to imposition of penalties, permit suspension or permit revocation.
501.2 Analytical Reguirements
All Pollutant analyses, including sampling techniques, to be submitted as part of a
Wastewater discharge permit application or report shall be performed in accordance with
the techniques prescribed in 40 CFR Part 136 and amendments thereto, unless otherwise
specified in an applicable categorical Pretreatment Standard. If 40 CFR Part 136 does
not contain sampling or analytical techniques for the Pollutant in question, or where the
EPA determines that the Part 136 sampling and analytical techniques are inappropriate
for the Pollutant in question, sampling and analyses shall be performed by using validated
analytical methods or any other applicable sampling and analytical procedures, including
EPA-approved procedures or procedures approved by the General Manager.
501.3 Right of Entry
A. Persons or occupants of premises where Wastewater is created or
discharged shall allow OCSD, or its representatives, reasonable access to
all parts of the Wastewater generating and disposal facilities for the
purposes of inspection and sampling during all times the Discharger's
facility is open, operating, or any other reasonable time. No Person shall
interfere with, delay, resist or refuse entrance to authorized OCSD
personnel attempting to inspect any facility involved directly or indirectly with
a discharge of Wastewater to OCSD's Sewerage System.
B. Where a User has security measures in place, the User shall make
necessary arrangements so that personnel from OCSD shall be permitted
to enter without delay for the purpose of performing their specific
responsibilities.
501.4 Notification of Spill or Slug Loading
A. In the event the Discharger is unable to comply with any permit condition
due to a breakdown of equipment, accidents, or human error, or the
Discharger has reasonable opportunity to know that a discharge will exceed
the discharge provisions of the User's permit, Sections 201(A) & (B) or
Table 1, Local Discharge Limits, the Discharger shall immediately notify
OCSD by telephone. If the Wastewater or material discharged to the sewer
has the potential to cause or result in a fire or explosion hazard, the
Discharger shall immediately notify the local fire department and OCSD.
Also see Reports of Potential Problems in this Article.
OCSD-48-69
501.5 Bypass Prohibition: Notification of Bypass
A. Bypass of Industrial Wastewater to the Sewerage System is prohibited.
OCSD may take enforcement action against the User, unless:
1. Bypass was unavoidable because it was done to prevent loss of life,
personal injury, or severe property damage;
2. There were no feasible alternatives to the Bypass, such as the use
of auxiliary treatment facilities, retention of untreated Wastes,
elective slow-down or shut-down of production units or maintenance
during periods of production downtime. This condition is not satisfied
if adequate backup equipment could have been feasibly installed in
the exercise of reasonable engineering judgment to prevent a
Bypass which occurred during normal periods of equipment
downtime or preventative maintenance; and
3. The Permittee submitted notices as required under Section 501.4(A).
B. If a Permittee knows in advance of the need for a Bypass, it shall submit a
written request to allow the Bypass to OCSD, if possible, at least ten (10)
days before the date of the Bypass.
C. OCSD may approve an anticipated Bypass at its sole discretion after
considering its adverse effects, and OCSD determines that the conditions
listed in Section 501.5(A)(1-3) are met.
D. A Permittee shall provide telephone notification to OCSD of an
unanticipated Bypass that exceeds its permitted discharge limits within four
hours from the time the Permittee becomes aware of the Bypass. A written
report shall also be provided within five (5) days of the time the Permittee
becomes aware or could reasonably have been aware of the Bypass. The
report shall contain a description of the Bypass and its cause; the duration
of the Bypass, including exact dates and times, and, if the Bypass has not
been corrected, the anticipated time it is expected to continue; and steps
taken or planned to reduce, eliminate, and prevent recurrence of the
Bypass. Failure to comply with the oral notice or written report may be
grounds for permit revocation.

and rules imposed upon it by Regulatory Agencies and to ensure that
OCSD's Sewerage Facilities and treatment processes are protected and
are able to operate with the highest degree of efficiency, and to protect the
public health and environment, specific enforcement provisions must be
adopted to govern the discharges to OCSD's Sewerage System by
Permittees or by facilities required to obtain Zero Discharge Certifications.
Certain violations may result in civil or criminal penalties for violation of
Pretreatment Standards and requirements, and any applicable compliance
schedule. Such schedules may not extend the compliance date beyond
applicable federal deadlines.
B. To ensure that all interested parties are afforded due process of law and
that non-compliance and violations are resolved as soon as possible, the
general policy of OCSD is that:
1. Any determination relating to a Zero Discharge Certification,
Probation Order, Enforcement Compliance Schedule Agreement
(ECSA), or Regulatory Compliance Schedule Agreement (RCSA)
will be made by the Division Head of the OCSD Pretreatment
Program, with a right of appeal by the Permittee to the General
Manager pursuant to the procedures set forth in Section 618.
2. Any permit suspension or revocation recommended by the Division
Head responsible for the OCSD Pretreatment Program will be heard
and a recommendation made to the General Manager by an OCSD
Department Head or other person designated by the General
Manager.
3. Actions and decisions by the Division Head or Department Head are
made pursuant to a delegation of authority by the General Manager
as authorized by Section 107 of this Ordinance.
4. The Board of Directors may adopt rules of procedure to establish the
conduct of certain administrative proceedings.
C. OCSD, at its discretion, may utilize any one, combination, or all enforcement
remedies provided in this Article 6 in response to any permit or Ordinance
violation.

602. DETERMINATION OF NONCOMPLIANCE WITH DISCHARGE LIMITS
A. Sampling Procedures
1. Sampling of all Permittees' facilities, Wastewater and discharges
shall be conducted in the time, place, manner, and frequency
determined at the sole discretion of OCSD.
2. Non-compliance with Mass Emission Rate limits, concentration
limits, permit discharge conditions, or any discharge provision of this
Ordinance may be determined by an analysis of a grab or composite
sample of the effluent of a User. Non-compliance with Mass
Emission Rate limits shall be determined by an analysis of a
composite sample of the User's effluent, except that a grab sample
may be used to determine compliance with Mass Emission Rate
limits when the discharge is from a closed (batch) treatment system
in which there is no Wastewater flow into the system when the
discharge is occurring, the volume of Wastewater contained in the
batch system is known, the time interval of discharge is known, and
the grab sample is homogeneous and representative of the
discharge.
3. All Wastewater samples must be representative of the User's
discharge. Any sample taken from a sample point is considered to
be representative of the discharge to the public sewer.
4. Wastewater monitoring and flow measurement facilities shall be
properly operated, kept clean, and maintained in good working order
at all times. The failure of a User to keep its monitoring facility in good
working order shall not be grounds for the User to claim that sample
results are unrepresentative of its discharge.
5. If a User subject to the reporting requirement in this section monitors
any regulated Pollutant at the appropriate sampling location more
frequently than required by the General Manager, using the
procedures prescribed in this Ordinance, the results of this
monitoring shall be included in the report.
603. ENFORCEMENT PROCEDURES AND APPLICABLE FEES
A. Self-Monitoring Requirements as a Result of Non-Compliance
1. If analysis of any sample obtained by OCSD or by a Permittee shows
non-compliance with the applicable Wastewater discharge limits set
forth in this Ordinance or in the Permittee's discharge permit, OCSD
may impose self-monitoring requirements on the Permittee.
OCSD-48-72
2. A Permittee shall perform required self-monitoring of constituents in
a frequency, at the specific location, and in a manner directed by
OCSD.
3. All analyses of self-monitoring samples shall be performed by an
independent laboratory acceptable to OCSD and submitted to OCSD
in the form and frequency determined by OCSD.
4. All self-monitoring costs shall be bome by the Permittee.
5. Nothing in this section shall be deemed to limit the authority of OCSD
to impose self-monitoring as a permit condition.
B. Purpose of Non-Compliance Resampling Fees
The purpose of the non-compliance resampling fee is to compensate OCSD
for costs of additional sampling, monitoring, laboratory analysis, treatment,
disposal, and administrative processing incurred as a result of the non-
compliance, and shall be in addition to and not in lieu of any penalties as
may be assessed pursuant to Sections 616 and 617.
C. Non Compliance Resampling Fees for Composite Samples
1. Each violation of a Permittee's permit limit or condition is a violation
of this Ordinance.
a) If analysis of any composite sample of a Permittee's discharge
obtained by OCSD shows a major violation by the Permittee
of the Mass Emission Rates or concentration limits specified
in the Permittee's discharge permit or in this Ordinance, then
the Permittee shall pay non-compliance resampling fees to
OCSD pursuant to fee schedules adopted by OCSD's Board
of Directors.
b) If analysis of any composite sample of a Permittee's discharge
obtained by OCSD shows a minor violation by the Permittee
of the Mass Emission Rates or concentration limits specified
in the Permittee's discharge permit or in this Ordinance, then
OCSD shall impose non-compliance resampling fees
pursuant to fee schedules adopted by OCSD's Board of
Directors.
2. The fees specified in subsection 603.C.1.a), C.1.b) and D herein
shall be imposed for each date on which OCSD conducts sampling
as a result of a violation by a Permittee.
OCSD-48-73
D. Non-Compliance Resampling Fees for Grab Samples and Self-Monitoring
Results
1. If analysis of any grab sample of a Permittee's discharge shows non-
compliance with any concentration limits as set forth in the User's
permit or in this Ordinance, OCSD may impose non-compliance
resampling fees, pursuant to fee schedules adopted by the OCSD
Board of Directors, for resampling conducted by OCSD as a result of
a violation by the Permittee.
2. If any self-monitoring analysis of a Permittee's discharge shows non-
compliance with any concentration limits or Mass Emission Rates as
set forth in the User's permit or in this Ordinance, OCSD may impose
non-compliance resampling fees, pursuant to fee schedules adopted
by the OCSD Board of Directors, for sampling conducted by OCSD
as a result of a violation by the Permittee.
603.1 Probation Order

WHEREAS, the State of California Regional Water Quality Control Board
("RWQCB") for the Santa Ana Region adopted Order R8-2002-0014, which prescribes
general waste discharge requirements prohibiting sanitary sewer overflows ("SSOs") by
sewer collection agencies; and
WHEREAS, in Order R8-2002-0014, the RWQCB found that one of the leading
causes of SSOs within the Santa Ana Region, which encompasses the District's service
area is "grease blockages;" and
WHEREAS, SSOs often caused by discharge of wastewater containing high
levels of fat, oils and grease ('FOG"), suspended solids, pathogenic organisms, and
other pollutants, may cause temporary exceedances of applicable water quality
objectives, pose a threat to the public health, adversely affect aquatic life, and impair
the public recreational use and aesthetic enjoyment of surface waters within the
District's service area; and
WHEREAS, the 2000-2001 Orange County Grand Jury ("Grand Jury") conducted
a survey among 35 wastewater collection and treatment agencies in Orange County
and concluded that one of the leading causes of SSOs and sewage spills is sewer lines
clogged from the accumulation of FOG discharged from Food Service Establishments;
and
WHEREAS, the Grand Jury further concluded that more effective methods of
minimizing grease discharges into the sewer system must be developed and
implemented to reduce the discharge of FOG to the sewer system in order to prevent
sewer blockages and SSOs; and
WHEREAS, Orange County Sanitation District ("Districr), together with 32 other
agencies, are collectively named as"Dischargers" in Order No. R8-2002-0014; and
WHEREAS, Order No. R8-2002-0014 requires the District to monitor and control
SSOs and to develop a FOG Control Program by December 30, 2004; and
Ms -oxs:g:WnB:OMM5 t
WHEREAS, in light of the overwhelming evidence that FOG is a primary cause of
SSOs, the District desires to implement a FOG Control Program to prevent SSOs; and
WHEREAS, the foregoing findings indicate that a FOG Control Program is
required for Food Service Establishments within the District's jurisdiction to comply with
waste discharge regulations and prevent the harmful effects of SSOs; and
WHEREAS, on November 17, 2004, the Board of Directors adopted Ordinance
No. OCSD-25 adopting FOG control regulations applicable to Food Service
Establishments; and
WHEREAS, Ordinance No. OGSD-25 requires Food Service Establishments

FOG Source Control Program and Enforcement Management System
1 INTRODUCTION
The Orange County Sanitation District(OCSD) is committed to complying
with the mandates set forth under the General Waste Discharge
Requirements for Sewage Collection Agencies in Orange County,
Order No. R8-2002-0014.As part of this mandate,OCSD is implementing
a Fats, Oils, and Grease (FOG) Source Control Program to Emit the
discharge of FOG and other debris that may cause sewerage collection
system blockages or Sanitary Sewer Overflows (SSOs). This is
accomplished through implementation and effective enforcement of
OCSD's FOG Ordinance OCSD-25(Appendix DI)by:
• Administering an extensive permuting program to control and regulate
FOG discharges from Food Service Establishments(FSEs);
• Requiring FSEs to implement Best Management Practices (BMPs) and
install grease interceptors,when applicable, to reduce FOG from their
wastewater prior to discharge to OCSD's sewerage system;
• Tracking compliance through inspection of FSEs, aggressive CCTV
monitoring of the sewer system to identify potential sources of sewer
blockages, and monitoring compliance with BMP requirements and
maintenance requirements for grease interceptors;
• Evaluating and screening the results of inspection and monitoring to
identify violations;and
• Consistently responding to all types of violations to ensure long-term
compliance.
OCSD's existing Wastewater Discharge Regulations OCSD-01 (Appendix
132) implements the general and specific prohibitions of the National
Pretreatment Program (40CFR403.5).
To achieve an effective and aggressive enforcement program, OCSD
established a FOG Enforcement Management System,which encompasses
the basic components required to cover all FOG control activities. In
developing the system, OCSD addressed the fundamental requirements
necessary to regulate FSEs,such as obtaining and evaluating information on
compliance of FSEs; identifying violations; and selecting appropriate
enfomement actions to resolve noncompliance in a timely, fair, and
consistent manner.

eas." pweAm,
During the development of OCSD's FOG Source Control Program,OCSD
and other WDR Co-Penn ittees needed to know the basic components of
such a program. Therefore, OCSD, on behalf of the WDR Co-Permittees
and in its role as regional facilitator, contracted the services of
Environmental Engineering&Contracting, Inc. (EEC),to conduct a FOG
Control Study. The final Phase I report was received in July 2003,and the
report fisted 12 potential `building blocks" for an effective FOG Source
Control Program, from which WDR Co-Pemvttees could develop
programs tailored in their site-specific conditions. A full copy of this study
is available from OCSD's Source Control Division.
OCSD also contracted EEC to conduct a Characterization Study of the hot
spots and FSEs in its area of jurisdiction to gather more specific
information for developing its FOG Source Control Program. The overall
aim was to determine the true came(s) of the hot spots. The study
encompassed visual observations of sewer lines using Closed Circuit
Television (CCTV) in the vicinity of the hot spots and inspecting and
cataloging each tributary FSE, including plotting the information in
Geographical Information System (GIS). The majority of the hot spots
were caused or exacerbated by structural issues and FOG discharges from
FSEs. Sometimes a repair effectively eliminated a hot spot caused by
structural issues, but in other cases, mitigation is not feasible and other
techniques must be employed to mitigate the hot spot With the data
gathered,OCSD is able to identify FSEs discharging FOG and is currently
prioritizing on those facilities discharging to hot spots. A copy of this study
is available from OCSD's Source Control Division.
As a result of these studies, OCSD has the data necessary for developing
the basis for its FOG Source Control Program.

PROGRAM
EW44+ d 404,%U 4 OLI. MV441'
OCSD established the following essential elements to implement an
effective FOG Source Control program for FSEs in die city of Tustin and
unincorporated areas within OCSD's jurisdiction:
3.1 Legal Authority
OCSD established a FOG Ordinance (OCSD-25) that provides the
legal authority necessary for implementing the FOG Source Control
Program. To prevent SSOs caused by FOG blockages of sewers,
OCSD's scope of authority includes:
• Authority to regulate all FSEs contributing FOG to the sewer
system
• Authority to require and issue Wastewater Discharge permits,
including:
• Authority to require FSEs to obtain permit
• Authority to require FSEs to submit pemdt applications
containing all data which OCSD deems relevant to permit
decisions and provisions for public access to data
• Authority to enter,Inspect,and sample to verify information
supplied by FSEs as well as to assess the FSEs'comphance
status
• Authority to incorporate local limits
• Authority to incorporate federal and state pretreatment
standards and requirements
• Authority to require self-monitoring record keeping,and
reporting by FSEs
• Authority to develop other appropriate permit conditions
• Authority to enforce permit violations.
OCSD's Board of Directors adopted the FOG Ordinance OCSD-25
on December 17, 2004, which was effective on ,January 1, 2005.
Subsequently, FOG Fee Resolution OCSD 05-04 (Appendix D3)
establishing FOG fees applicable to FSEs was passed and adopted
on March 23,2005,and was effective on May 1,2005.
P.f 3
FOG Source Control Program and Enforcement Management System
The following is a summary of the core requirements of the FOG
Ordinance:
Permit Requirement
• FSEs are required to obtain a FOG Wastewater Discharge
Permit to discharge wastewater into the sewer system.
Permit Exemptions
• A limited food preparation establishment is not considered an
FSE and is exempt from obtaining a FOG Discharge Permit.
Exempted establishments shall be engaged only in reheating,
hot holding,or assembly of ready-to-eat food products and,as a
result, there is no wastewater discharge containing a significant
amount of FOG. A limited food preparation establishment
does not include any operation that changes the form,flavor,or
consistency of food.
Permit Fee
• The Permit Fee is $100/year to cover permit issuance and
maintenance.There is no change in existing user fees specific to
FSEs.
Prohibitions
• Use of food grinders. Installation of food grinders in the
plumbing system of new constructions of FSEs is prohibited.
Furthermore, all food grinders shall be removed from all
existing FSEs within 180 days after notification, except when
expressly allowed by the FOG Source Control Program
Manager.
• Introduction of any additives into a FSE's wastewater system
for the purpose of emulsifying or biologically/chemically,
creating FOG for grease mmediation or as a supplement to
interceptor maintenance, unless a specific written authorization
from the FOG Source Control Program Manager is obtained.
• Disposal of waste cooking oil into drainage pipes. All waste
cooking oils shall be collected and stored properly in receptacles,
such as barrels or dorms, for recycling or other acceptable
methods of disposal.
• Discharge of wastewater from dishwashers to any grease crap or
grease interceptor.
• Discharge of wastewater with temperatures in excess of 140T
to any grease control device, including grease traps and grease
interceptors.
P.f4
FOG Source Control Program and Enforcement Management System
• Discharge of wastes from toilets,urinals,wash basins,and other
fixtures containing fecal materials to sewer lines intended for
grease interceptor service,or vice versa.
• Discharge of any waste including FOG and solid materials
removed from the grease control device to the sewer system.
Grease removed from grease interceptors shall be wastchauled
periodically as part of the operation and maintenance
requirements for grease interceptors.
• Operation of grease interceptors with FOG and solids
accumulation exceeding 25%of the total design hydraulic depth
of the grease interceptor(25%Rule).
Requirement to Implement Best Management Practices(BMPs)
• FSEs me required to implement BMPs in their operation to
rrtittimize the discharge of FOG to the sewer system.
General Requirement for FOG Pretreatment
• Service Establishments are required to preheat their wastewater
using grease interceptors to remove FOG prior to discharge to
the sewer system. Waivers or Variances are allowed when
applicable,but space and plumbing segregation are required for
future interceptor installation.
Implementation of FOG Pretreatment Requirement for New
Construction of FSE.
• New construction of FSEs is required to install grease
interceptors prior to commencing discharge of wastewater to
the sewer system.
Implementation of FOG Pretreatment Requirement for Existing
FSEs
• For existing FSEs in general, the requirement to install and to
properly operate and maintain a grease interceptor may be
conditionally delayed in its implementation (through a
conditional waiver) by the FOG Control Manager for a
maximum period of three years from the effective date of the
Ordinance.
• Installation of grease interceptors are required within 180 days
after notification for existing FSEs that have caused or
contributed to grease related blockage in the sewer system, or
which have sewer laterals connected to hotspots,or which have
been determined to have major impact to the sewer system by
the FOG Source Control Program Manager based on
inspection or sampling.
P.#s
FOG Source Control Program and Enforcement Management System
• Installation of grease interceptors is required for Existing FSEs
undergoing remodeling or a change in operations as defined in
the Ordinance,or for Existing FSEs that change ownership and
undergo remodeling or a change in operations as defined in the
Ordinance.
Variance from Grease Interceptor Requirement
• A variance may be issued to allow alternative pretreatment
technology that is, at least, equally effective in controlling the
FOG discharge in lieu of a grease interceptor, to FSEs
demonstrating that it is impossible or impracticable to install,
operate, or maintain a grease interceptor. The FOG Source
Control program Manager's determination to grant a variance
will be based upon, but not limited to, evaluation of the
following conditions:
1. There is no adequate space for installation and/or maintenance ofa
grease interceptor.
2. There is no adequate slope for gravity flow between kitchen
plumbing fixtures and the grease interceptor and/or between the
grease interceptor and the private collection lines or the public
sewer.
3. The FSE may justify that the alternative pretreatment technology
is equivalent or better than a grease interceptor in controlling its
FOG discharge.In addition,the FSE must be able to demonstrate,
after installation of the proposed alternative pretreatment, its
effectiveness to control FOG discharge through downstream
visual monitoring (Closed Circuit Television or CCTV) of the
sewer system, for at least duce months, at its own expense. A
Variance may be granted if the results show no visible
accumulation of FOG in its lateral and/or tributary downstream
sewer lines.
Conditional Wallace from Installation of Grease Interceptor
• Conditional Waivers from installation of grease interceptors
may be issued to FSEs that have been determined to have
negligible FOG discharge and insigridicant impact to the sewer
system.This waiver may also be issued to existing FSEs to delay
implementation of the requirement up to a maximum of three
years from the effective date of the Ordinance. The FOG
Source Control Progearn Manager's determination to grunt or
revoke a conditional waiver shall be based upon,but not limited
to,evaluation of the following conditions:
1. Quantity of FOG discharge as measured or as indicated by the sim
of FSE based m seating capacity,number of meals served menu,

guidelines adopted pursuant to the FOG Source Control Program.
OCSD may change the maintenance frequency at any time to
reflect changes in actual operating conditions in accordance with
the FOG Source Control Program.Based on the actual generation
of FOG from the FSE,the maintenance frequency may increase or
decrease.
4. The onmes/operator of a FSE may submit a request to the FOG
Source Control Program Manager requesting a change in (be
rammtenance frequency at my time. The FSE has the burden of
responsibility to demonstrate that the requested change in
frequency reflects actual operating conditions based on the
average FOG accumulation over time and meets the requirements

3.2 Systematic Identification and Inventory of FOG
Sources
3.2.1 Initial Inventory of FSEs
OCSD initially identified FSEs within its jurisdiction by inspecting
and characterizing each FSE and subsequently determined individual
Pay 1r
FOG Source Control Program and Enforcement Management System
potential to generate and discharge FOG to the sewer system. This
was done as part of the FOG Characterization Study conducted by
Environtnenral Engineering and Contracting, Inc. (EEC) on behalf
of OCSD.The purpose of the study was to provide key information
and program recommendations for the development of OCSD's
FOG Source Control Program to prevent FOG-related SSOs.
A total of 145 FSEs were initially identified to be significant FOG
dischargers and were issued penrtits on January 1, 2005, based on
inspection and evaluation of each FSE and the following
assessments:
• Problem areas in the sewer system(hot spots),as manifested by
more frequent deaning and maintenance, were identified and
inspected using Closed Circuit Television(CCTV).This enabled
OCSD to detemilne FSEs contributing to the existence of hot
spots and identify other potential sources of FOG.
• OCSD's service area was mapped out utilizing Geographic
Information System (GIS) software to georeference critical
information such as streets, sewer lines and flow, directions,
location of FSEs and hot spots,location of historical SSOs,etc.
This map enabled OCSD to better understand occurrence of
SSOs and evaluate potential impact of each ESE based on its
proxintity and relative location to hot spots.
Utilizing the results from the GIS findings,OCSD ranked FSEs that
have the probability of causing sewer blockages and impact to
downstream hotspots. This served as the basis to prioritize major
pemtit requirements, such as installation,operation and maintenance
of a grease interceptor.
3.2.2 Program Provisions to Update Inventory of FSEs
To ensure that all significant FOG dischargers are permitted and
regulated, OCSD established mechanisms to update its inventory of
FSEs on a routine basis. The following are implemented to identify
new or potential FSEs that are not currently on penrtit
• OCSD pattnered with the City of Tustin's Community
Development Departu ent- Building Division, to identify new
construction or major renovation of FSEs exceeding $50,000.
When a building permit is issued by the Building Division, the
prospective FSE is also given a FOG Wastewater Discharge
Permit Application.Upon notification by the Building Division,
OCSD staff conducts an inspection to collect the necessary
information needed to issue a new FOG Wastewater Discharge
Permit An Inspection Card, issued by the City of Tustin for
each building pemuq contains a sign off provision for OCSD to
provide the opportunity to inform the city's Building Division
that the ESE has met OCSD's requirements,including issuance
PV 11
FOG Source Control Program and Enforcement Management System
of a valid FOG Wastewater Discharge Permit This allows the
city to complete the business license procedure and issue the
certificate of occupancy to die FSE. This procedure ensures
that OCSD's FOG discharge requirements are satisfied prior to
discharge.
• OCSD obtains and reviews, on a periodic basis, a fist of FSEs
from the City of Tusdn's Business License Division to identify
new FSEs. This enables OCSD to identify new FSEs based on
change of ownership that did not go through the building
permit process.
• On an annual basis, OCSD reviews a comprehensive fist of
FSEs inspected by the Orange County Health Care Agency
(OCHCA) to identify FSEs that are not currently permitted by
OCSD.
• As a condition of the FOG prrnut, current FSEs are required
to notify OCSD of any changes to their company information,
such as changes in ownership. A Facility Information Update
Form,available in the FOG permit package,is provided for this
purpose. The update form will initiate the appropriate follow-
up response such as an inspection or the mailing of a permit
application(for new owners).
3.3 Permitting Program
In addition to the FOG Ordinance,OCSD utilizes FOG Wastewater
Discharge Permits as a control mechanism to effectively implement
FOG control requirements to FSEs. Competently staffed with
personnel well trained in the pretreatment program, OCSD
processes permits efficiently using established procedures and time
frames together with automation. This ensures timely issuance and
application of appropriate permit conditions.
3.3.1 Comprehensive Permit
A permit is effective only when it is comprehensive enough to
describe all requirements and control parameters required of a
permitter. To ensure that each FSE understands its unique
obligations, OCSD issues a permit that comprehensively defines the
FSEs'responsibilities;the regulations to which FSEs need to adhere;
and specific requirements in terms of self-monitoring frequency,
reporting requirements,etc.
The permit issued to an FSE authorizes the discharge of wastewater
to OCSD's sewerage system,and describes,in a single document,all
the duties and obligations of the FSE, including applicable FOG
pretreatment requirements. Permits allow for the systematic
Prat 12
FOG Source Control Program and Enforcement Management System
integration of all applicable requirements and greatly facilitate
enforcement of any noncompliance. An example of the FOG
Wastewater Discharge Perdt is shown in Appendix El.
3.3.2 Major Permit Requirements
Some of the major requirements of the permit that help ensure an
effective FOG control program include, but are not limited to, the
following:
• Mandatory implementation of Mtcbm BMPs for all FSEs.
• Installation, operation, and maintenance of grease interceptors,
when applicable.
Although all permits include die requirement for installation,
operation, and maintenance of grease interceptors, waivers are
initially issued to FSEs believed to have minor impact based on
current information. An ongoing identification and verification of
major FOG sources through FSE inspections and CCTV are integral
components of OCSD's FOG Source Control Program. This
enables OCSD to revoke waivers and pursue installation of grease
interceptor for FSEs that are known to have major impact. Of the
145 permits initially issued by OCSD on January 1,2005,about 20%
were required to install,operate and maintain a grease interceptor.
3.3.3 Permit Duration
FOG Wastewater Discharge Permits issued by OCSD are typically
for two years from the date of issuance and are updated, reviewed
and renewed bi-annually. Prior to expiration of the permit, die FSE
is required to complete and submit a permit renewal application to
allow for re-evaluation of its existing permit.
3.3.4 Permit Informational Materials
OCSD has taken extra efforts to provide each permittee with a
comprehensive permit binder that contains all die informational
materials necessary to understand and comply with OCSD's FOG
Source Control Program and the FOG discharge requirements.The
binder includes the following:
• FOG Wastewater Discharge Permit(Appendix El)
• Kitchen BMPs mining materials (Appendix E2) in the form of
a DVD video and reading material.A poster that is required to
be displayed in the kitchen area is also provided separately.
• Informational Fact Sheets (Appendix E3) on the following

3.4 Enforcement Program
3.4.1 Monitoring Program
The monitoring program is an integral part of OCSD's enforcement
program. OCSD performs routine and non-routine monitoring of
FSEs to enforce the provisions of the FOG Ordinance and their
FOG Wastewater Discharge Permits,and to identify noncompliance.
In general,the monitoring program encompasses:
• FSE Self Monitoring which provides feedback to OCSD on the
seams of die required BMP implementation and grease
interceptor maintenance;
• Routine Onsite Facility Inspections conducted by OCSD
staff/representative to monitor overall status of compliance;
• Follow-up Inspections and Verification to determine if FSE has
implemented required corrective actions;
• Compliance Audit to evaluate repeated violations;
• Inspections for Bi-Annual Permit Renewal to gather
information needed for establishing permit conditions during
permit renewal;and
• Downstream Sewer Dine Inspections using CCTV to provide
visual observation of FSE laterals and detect major FOG
contributors that are not apparent during routine inspections.
Details of the monitoring program are discussed in Section 6.
3.4.2 Enforcement Management System
PV 14
FOG Source Control Program and Enforcement Management System
OCSD believes that the success of its FOG Source Control Program
is highly dependent not only on its ability to administer extensive
permitting and to monitor FSEs through inspection,but also on die
implementation of an effective and aggressive enforcement program
that is capable of detecting violations and consistently responding to
all types of noncompliance. OCSD provides a comprehensive range
of enforcement options that are used to respond to violations within
the legal authority granted by OCSD's FOG Ordinance. The
following is a fist of available enforcement actions that have been
found to be effective in achieving and maintaining long-term
compliance:
Cmm.tiVe Action Notices Revocation of Waiver from Grease
Notices of Violation Inta.'aar Installation
Noncompliance Fees Revocation of Variance from Grease
• Compliance Follow-Up Inspection Interceptor Requhements

• Increased Greces Intercept., • Emergency Suspension Order
Pumping/Maintenance Civil Action b Recover Civil
• Order to Cease Noncompliant Penalties
Gatherge Injunction
• Compliance Schedule Agreemm, • Physical Terminsdon of Service
• Administrative ComplaincFane Criminal Penalties
To achieve timely and effective implementation of the FOG Source
Control Program, OCSD established an Enforcement Management
System, which provides systematic procedures to identify
noncompliant FSEs and determine appropriate enforcement actions
that must be implemented within established time frames. OCSD's
Enforcement Management System includes procedures that are
applied to enforce the FOG control program requirements and to
track compliance. Through the Enforcement Management System,
OCSD is able to:
• Identify and investigate instances of noncompliance;
• Establish enforcement responses that are appropriate in relation
to the nature and severity of the violation and the overall degree
of noncompliance;and
• Provide uniform application of enforcement responses for
comparable levels and types of violations, and ensure adequate,
consistent,and timely enforcement actions.
OCSD's Enforcement Management System encompasses all die
facets of FOG source control activities from permitting to
enforcement. This enforcement management system is necessary to
effectively administer all the requirements of the FOG Source
Control Program. It provides a systematic way of determining
whether FSEs are complying with the FOG Ordinance through the
requirements specified in the control mechanisms and legal
authorities, and in determining how and when to respond to
noncompliance. A comprehensive discussion of OCSD's
Pate lS
FOG Source Control Program and Enforcement Management System
Enforcement Management System can be found in the following
sections.
3.5 Staffing Resources and Training
3.5.1 Staffing Resources
The effectiveness of the control mechanisms (permit and ordinance)
established for implementing the FOG Source Control Program is
enhanced by a well-qualified and competent staff. OCSD's Source
Control Division administers the FOG Source Control Program.
This program is staffed by five highly qualified Environmental
Specialists/Engineers with bachelor's/master's degrees in either
science or engineering and with years of experience in implementing
the National Pretreatment Program. In addition, OCSD utilizes the
services of Environmental Compliance Inspection Service (ECIS) to
conduct routine inspections for BMP and grease interceptors. The
continued success of OCSD's pretreatment program is enhanced by
the expertise, experience, and skills of the staff developing and
implementing the program. These resources are utilized both to
attain the goals of the FOG Source Control Program and to work in
cooperation with FSEs and the public to protect the environment.
3.5.2 Training
Training is an integral pare of OCSD's staff development program.
The need for a well-trained staff that is thoroughly familiar with the
pretreatment regulations, FOG Source Control Program, policies
and procedures, and computer applications cannot be over-
emphasized. Therefore, OCSD's Source Control Division has
established formal training programs for both new and existing staff
utilizing both internal and external resources.
3.5.2.1 Nev Stag'
The training of new staff is an intensive process lasting six months to
one year, starting with a formal introduction to the program under
the guidance of senior staff. A training schedule is developed,
tailored to the position and needs of the new staff,which involves
familiarization with materials on pretreatment regulations, FOG
Ordinance and policies and procedures, kitchen BMPs, and FOG
pretreatment equipment and waste management practices. After
completing the formal training program, the knowledge obtained is
further reinforced through on-the-job training.
P.g 16
FOG Source Control Program and Enforcement Management System
3.5.2.2 Existing Staff
The training of existing staff is on-going, and it involves both
technical and general training to maintain and augment skills and
knowledge needed to perform the job.
• On a continuous basis, staff receives training on both
commercial computer software and OCSD's programs created
in-house to enable the staff to effectively and efficiently
conduct their duties. Examples of these programs include
Excel,Word,Access, and OCSD's FOG software. Other types
of training include time management, project management,
budget development, performance assessment, confined space
entry, first aid, First Responder training, LEL detection,
defensive driving,and developing management and supervisory
skills. Continuous on-the-job training through regular staff
meetings is conducted to update staff on new regulations,
pollution prevention, pretreatment system, policies and
procedures,etc. OCSD also provides opportunities,in the form
of tuition reimbursement and flexible schedules, for staff to
increase their knowledge by taking courses at colleges and
universities that relate to the duties performed by staff.
• Staff also participates in conferences and training seminars
throughout the country to be kept knowledgeable on the latest
technologies and regulations. For example, staff regularly
attend the Cal FOG Work Group, California Water
Environment Association (CWFA), National Association of
Clean Water Agencies (NACWA, formerly AMSA), and Water
Environment Federation (WEF) conferences and training
seminars, and field staff have participated in conferences and
training seminars throughout the country to be up-to-date on
the latest technologies available in sampling and monitoring
equipment.
• When new programs are implemented,staff receives specialized
mining to execute and conduct the tasks required by the
program. For example, at the implementation phase of the
FOG Source Control program, OCSD's staff attended an
Advanced Training Course on the Control of Fats, Oils, and
Grease sponsored by EPA, WEF and CWEA. Such training
program instructs staff and familiarizes them with the issues,
technical aspects,and policies and procedures of the program.
3.6 FSE Outreach
OCSD recognizes that its ability to be proactive and effective is also
dependent upon public outreach and education. OCSD's basic
principle is working with FSEs to protect the environment and
public health. OCSD strives not only to keep the public involved,
Pay 17
FOG Source Control Program and Enforcement Management System
but also to become partners with FSEs in developing and
maintaining its environmental protection programs. It has been
OCSD's experience that the FOG Source Control Program is more
effective and successful if FSEs understand the purposes and goals
of the program, and if FSEs are active participants in developing a
practical and equitable program.
Interaction with FSEs occurs on a day-to-day basis, as part of the
daily operation of the FOG Source Control Program and through a
variety of formes and venues which bring together FSEs on the local
level. As part of OCSD's philosophy of service to the community
and of developing equitable, practical programs, its outreach
activities include working with other local agencies to bring about
regulations that"make sense"to FSEs,OCSD,and the community.
The following an, examples of the more important and unique
outreach activities and programs OCSD has undertaken:
3.6.1 FOG Ordinance Advocacy
Dating the initial development of the FOG Ordinance, OCSD
served as the lead agency in creating a model ordinance for Orange
County. OCSD worked with other co-pemdttees in Orange County
to solicit inputs in order to ensure that the regulations established are
comprehensive and can be practically implemented to achieve the
desired environmental results.The model ordinance served as a good
starting point for co-permitmes to develop and adopt a FOG
Ordinance that suits their local need. It was adopted by OCSD and
some of the co-pemuttees.
3.6.2 Stakeholder Involvement and Education
OCSD conducted outreach for FSEs within its jurisdiction through
workshops, printed materials mailed to FSEs, and the internet to
solicit active participation and feedback on the development of the
FOG Ordinance. Beginning August through December 2004, prior
to implementation of the FOG Source Control Program in]anuary 1,
2005, OCSD mailed informational materials to FSEs in the form of
Fact Sheets (Appendix E3), to promote awareness about the
problem associated with FOG,to educate them on what they can do
to help minimize the discharge of FOG,and to create a mindset that
the FOG discharge regulations is upcoming and will be implemented
through permits and enforcement.

3.7 Collaboration with Sewer Maintenance,
Engineering Design, Source Control, and
Communication Groups
The FOG Source Control Program alone is insufficient to ensure
that FOG related SSOs will be eliminated. In order to be effective,it
is also necessary to work with the following.
• Engineering Department to prioritize and correct structural
defects
• Maintenance Department to eliminate mot infestation in the
sewer, track the emergence of trouble spots (hotspots) in the
collection system and take the necessary steps to establish
appropriate maintenance frequencies
1k Communications Department to provide public outreach to
minintize residential FOG discharge.
A collaborative effort is established between the Maintenance
Department, Engineering Department, Communications
Department, and the Source Control Division to develop a unifying
strategy in eliminating SSOs. It is important for the Source Control
Division to maiucain communication and logistical connectivity to
the work practices of the other workgmups. Information obtained
from the FOG Source Control Program during the course of its
implementation will be fed to the other groups to develop strategies
to optimize cleaning of sewer lines and eliminate roots, to identify
and fix sewer fine structural problems, and to further educate the
public.
OCSD is committed in implementing an effective and practical FOG
Source Control Program that considers the economic impact in
implementing requirements to FSEs as well as the benefits derived
towards achieving the desired environmental results. Although an
initial program has been established, ongoing efforts to further
improve the implementation of the FOG Source Control Program
will be pursued.

4 OVERVIEW OF OCSD'S FOG
ENFORCEMENT MANAGEMENT
SYSTEM
Now 4 ,vim
OCSD's FOG Source Control Program is administered through the FOG
Enforcement Management System. The system is a network of four
interdependent components:
1. Control Mechanisms (FOG Ordinance and Permits) to establish authority for
regulating FSEs;
2. Monitoring Program to investigate instances of noncompliance;
3. Compliance Screening to identify violations;and
4. Implementation of Enforrement Actions.
Linked together, these components serve as the framework in effectively
enforcing OCSD's FOG Source Control Program. Each component is
comprised of procedures on how and when to conduct each activity,and is
established to define personnel responsibilities in administering the
program.

FOG Source Control Program and Enforcement Management System
Control mechanisms aze the foundation of the FOG Enforcement
Management System. OCSD regulates FSEs through the FOG Discharge
Permit (pemiit) and the FOG Ordinance. The permit and die FOG
Ordinance define the FSEs'responsibilities;the regulations to which FSEs
need to adhere;and specific discharge requirements.The existence of these
control mechanisms,however,is not enough to ensure compliance by FSEs
with die regulations. OCSD recognizes that it must be able to act upon and
effectively enforce the terms of these control mechanisms.
To determine and investigate instances of noncompliance, OCSD
administers a monitoring program by inspecting FSEs, tracking
implementation of BMPs, monitoring maintenance of grease interceptors,
and by tracking all other requirements imposed. Inspections include
evaluations and assessments of the FSEs' operations and grease
interceptors,and are documented by inspection reports.
Because of the large volume of information handled in maintaining and
evaluating pemiit and enforcement activities, database management
becomes an integral part of the FOG Enforcement Management System.
OCSD has a sophisticated computer network for this purpose, which
utilizes advanced database management softwares such as Oracle, to
enhance information storage, retrieval, processing, and evaluation. A
custom software specifically designed to administer the FOG Source
Control Program is in place, to ensure consistency and efficiency of
implementation. The software organizes and enhances monitoring and
tracking activities as well as implementation of enforcement actions.
Pertinent current information on FSEs is stored in the computer database;
similarly, hard copies of documents are stored in files. The FOG software
and database system are capable of storing inspection reports, BMP
reporting requirements,and grease interceptor maintenance reports among
others obtained by OCSD. In addition, the computer tracks due dates for
report submittals and requirements imposed on FSEs, and also generates
reminders to FSEs prior to the due dates.
With the FSEs' requirements and prohibitions established trough the
control mechanisms, and the data gathered from the monitoring and
tracking activities, violations are identified through systematic compliance
sueenvig. The compliance screening process involves review of available
information to sort out noncompliant dischargers for appropriate
enforcement response. This process automatically generates Notices of
Violation that are sent to FSEs. All other violations not amenable to
computer tracking are being determined manually, in a systematic manner,
in accordance with established policies and procedures.
The violations and discrepancies that are identified during the compliance
screening process are reviewed by the appropriate personnel to evaluate the
type of enforcement response needed. OCSD staff identifies types of
responses that are appropriate based on the nature of the violation, the
frequency of the violation, the magnitude of the violation, the duration of
the violation, the potential impact of the violation, and the good-faith
efforts of the violator to eliminate noncompliance. After selection of the
PV 21
FOG Source Control Program and Enforcement Management System
appropriate response, the enforcement action is implemented by specific
Personnel within a reasonable time frame.
The culmination of all of the above activities enables OCSD to maintain
internal coordination and management of the FOG Source Control
Program in a systematic and consistent manner. Through the FOG
Enforcement Management System, OCSD intends to implement
monitoring and enforcement responsibilities in a consistent, fah and timely
manner.

5 CONTROL MECHANISMS
UP1G" 'e
The FOG Ordinance and the FOG Wastewater Discharge Permit are
control mechanisms that allow OCSD to implement the FOG Source
Control Program. These control mechanisms serve as the regulatory
foundation for providing OCSD with the legal authority to implement the
program.
5.1 FOG Ordinance
The FOG Ordinance adopted by OCSD sets forth uniform
requirements for all FSEs in OCSD's service area of responsibility,
to comply with the General Waste Discharge Requirements Order.
The Ordinance authorizes the issuance of FOG Discharge Permits
to limit FOG discharges to the sewer system; authorizes
inspection/monitoring and enforcement activities; establishes
adtrdnistrarive procedures; and provides for the setting of fees for
the equitable distribution of costs resulting from the implementation
of the FOG Source Control Program.
5.2 FOG Wastewater Discharge Permit
OCSD's FOG Ordinance prohibits the discharge of FOG from
FSEs without valid FOG Discharge Permits. Therefore, OCSD is
administering a permit program for FSEs utilizing procedures that
allow for the:
• Identification of new FSEs and characterization of their FOG
discharges,
• Identification of significant process and/or discharge changes at
existing FSEs,and
• Issuance of petmits to regulate FSEs'FOG discharges
FOG Wastewater Discharge Permits issued to FSEs contain:
S Discharge prohibitions and discharge limitations;
S Schedules for self-monitoring and reporting;
PV 23

• Statements of duration and non-transferability;
• Legal authority of OCSD to revoke the sewer discharge
privileges and to modify the pemut;
• Penalties;
• Record keepingand notification requirements;
• Severability;and
• Permit conditions,as necessary.
5.2.1 Permit Processing and Issuance
OCSD implements an efficient permitting program through timely
processing and issuance of permits,comprehensive permit evaluation
to ensure application of correct permit conditions, and automated
permit generation. The following describe these aspects in detail:
5.2.1.1 Timeliness of Permit Processing and Issuance
Permit issuance is frequently delayed when the applicant does not
provide complete information and other requirements in the
application,or when there are no established internal procedures and
time table for processing and issuing a permit To resolve this
problem, OCSD established the following tools to ensure timely
issuance of a permit:
• A pemut application package (Appendix E7, which contains
comprehensive information on how to obtain a FOG
Wastewater Discharge permit and easy-to-follow guidelines on
how to fill-out an application form, is made available to all
permit applicants. The brochure describes OCSD's FOG
wastewater discharge penult program, permit requirements,
how to apply and obtain a permit, permit conditions, facilities
requirements,permit application review and evaluation process,
specific instructions on how to fill out an application, and
guidelines on drawings and information submittal requirements.
This information provides applicants with sufficient knowledge
necessary to be able to respond effectively in complying with all
the permit application requirements. A pemut application
package checklist is also provided to, ensure completeness of
submittal requirements.
• When a pemut application is received, OCSD follows
established permitting procedures to ensure issuance of an
accurate permit. Based on this, it is expected that new peones
will be issued within four weeks,and all existing pemdts will be
renewed prior to or by the expiration date.

5.2.1.2 Comprehensive Permit Evaluation to Ensure Application of
Correct Permit Conditions
OCSD conducts a thorough review of the permit application and a
comprehensive evaluation of FOG sources through an inspection of
the facility,to determine applicable permit conditions. The adequacy
of the pretreatment system and BMPs in place are also evaluated to
ensure compliance. After final evaluation, the information is
summarized and processed quickly using a computer permit
generator program. Prior to issuance, QA/QC procedures are
followed to ensure accuracy of the permit.
5.2.13 Automated Permit Generation
To enhance management of permit information for each FSE,
OCSD maintains a relational database system that allows efficient
data storage and retrieval for a variety of applications. This has led
to the development of a computerized permit generator developed
in-house, which allows a permit document to be generated in
appeozlmately less than ten minutes.
After detailed evaluation of the pertinent information and the
applicable permit conditions as previously described, the final
information is summarized and entered in the pemut generator
program. The permit document,containing all pertinent information,
is quickly generated and is ready for issuance in a matter of minutes.

6 MONITORING FSEs
How 44us-e" a(, �awari hl;awt wu
4W"
6.1 Methods of Investigating Instances of
Noncompliance
OCSD's monitoring program is used to evaluate the compliance
scams of FSEs in relation to applicable permit and ordinance
requirements. The monitoring progrun consists of:
• Tracking compliance with permit and ordinance requirements
through facility inspections;
• Tracking status of implementation of BMPs and Grease
Control Device Operations and Maintenance through self-
monitoring program;
• Receiving and evaluating reports as specified in the FSEs'
permits or as required by any enforcement actions;
• Investigating instances of noncompliance,producing admissible
evidence through visual observation of sewer laterals and sewer
lines downstream using closed-circuit television (CCTV), as
necessary;and
6 Maintaining a computerized compilation of pertinent data
regarding all FSEs that is complete and accurate, in order to
facilitate the compliance screening process.
The following describes in derail the monitoring and tracking activities
performed by OCSD:
6.2 FSE Self-Monitoring
6.2.1 Self-Monitoring to Track Implementation of Required
Best Management Practices
OCSD requires all FSEs to implement BMPs and to report the status
of implementation every six months. Minimum requirements for
implementation of BMPs are specified in the FSE's pemut All self-
monitoring is required to be conducted in accordance with OCSD's
PVfs
FOG Source Control Program and Enforcement Management System
guidelines as specified in the FSEa' perilt, The self-monitoring
results sobrrutted w OCSD are evaluated and used as a means to
detemrine compliance. If the results show noncompliance, the FSE
is inspected to confirm the noncompliance and a Corrective Action
Notice is issued accordingly,to require immediate implementation of
corrective measures. A Notice of Violation with a Noncompliance
Fee is issued when die FSE fails to implement the required
correction during a follow-up verification inspection.
OCSD utilizes a computer system to administer the self-monitoring
program from the initial notification to final submittal of reports or
implementing required enforcement responses. FSEs are initially
notified at the beginning of the six-month reporting period to
implement BMPs and are also sent a reminder notice together with
the official Best Management Practices Monitoring Report Forms.
Submittals are tracked and late notices are sent when reports are not
submitted on time.The reports generated by this automated process
are manually verified and checked by responsible personnel prior to
final release. After final verification, the results become part of the
FSE's pemnanent file and compliance record in the computer
database.
6.2.2 Self-Monitoring to Track Implementation of Maintenance
Requirements for Grease Interceptors
OCSD also requires FSEs with grease interceptors to maintain their
grease interceptors at a specified frequency and to report these
activities every six months. The permit specifies the minimum
requirements for grease interceptor maintenance.Similar to the BMP
self-monitoring, FSEs are also required to submit self monitoring
reports to OCSD. Reports submitted to OCSD are evaluated and
used as a means to determine compliance. If the results show
noncompliance, the FSE is inspected to confirm the noncompliance
and a Corrective Action Notice is issued accordingly, to require
immediate implementation of corrective measures. A Notice of
Violation with a Noncompliance Fee is issued when the FSE fails to
implement the requited correction during a follow-up verification
inspection. Implementation procedures for the Grease Interceptor
self-monitoring requirement are similar to the BMP self-monitoring
requirement.
6.3 Inspections
OCSD conducts routine and non-routine inspections as a means of
verifying an FSE's compliance with its discharge permit and OCSD's
Ordinance. The following types of inspections are commonly done:
Pair 27
FOG Source Control Program and Enforcement Management System
6.3.1 Routine Onsite Facility Inspections
On a routine basis, FSEs with grease interceptor requirements are
inspected periodically to verify proper maintenance and operation of
grease interceptors and compliance with the 25% rule. OCSD also
conducts inspections of FSEs to detemdne instances of
noncompliance with BMP requirements and other permit
requirements. The inspections may include interview with FSE
representative, inspection of grease removal devices, and visual
observation of kitchen practices as it relates to FOG generation.
6.3.2 Follow-up Inspection and Verification
When a Corrective Action Notice is issued, a follow-up inspection
and verification is conducted to determine if the FSE has complied
with die required corrective actions to resolve the noncompliance
problem. When an FSE fails to correct the problem based on the
findings of this inspection,a Notice of Violation is issued along with
the corresponding Noncompliance Fee.
6.3.3 Compliance Audit
This is a special inspection for FSEs with repeated violations to
identify and assess the cause of the recurring noncompliance
problems and to establish the required corrective actions. OCSD's
staff conducts a compliance audit of the facility, including a
thorough review of due kitchen practices, waste/wastewater-
generating sources, waste management practices, and adequary of
the pretreatment system.
6.3.4 Inspection for Bi-Annual Permit Renewal
This is a comprehensive inspection conducted every two years. It
provides a derailed compliance check as well as information needed
to re-evaluate the permit during permit renewal. These inspections
include evaluation of the kitchen pounces and grease interceptor,
review of waste manifests and other disposal documents,compliance
evaluation, and a review of applicable regulations, policies and
procedures for the implementation of the FOG program.
6.3.5 Downstream Sewer Line Inspections
To further confirm compliance with the requirements of the FOG
Source Control Program, OCSD conducts routine inspections of
downstream sewer lines and laterals from FSEs using Closed Circuit
Television (CCTV). This provides opportunity to pinpoint sources
of illegal FOG discharges not detected during onsite inspections.
PVfa
FOG Source Control Program and Enforcement Management System
With the visual observations obtained using CCTV,OCSD is able to
identify FSEs that have major impacts and, subsequently, require
them to install adequately sized grease interceptors to resolve the
problem. OCSD regularly conducts downstream monitoring and
uses it as an effective means to identify major FOG contributors and
further identify groups of dischargers that either collectively or
cumulatively impact the sewer. CCTV inspection has been
demonstrated to be a very useful tool in monitoring trouble spots to
prevent SSOs and eventually eliminating trouble spots.
6.4 Data Management
OCSD maintains a computer data management system for storage,
retrieval,and processing of information pertaining to all permit- and
enforcement-related activities. The data management system is
capable of handling and processing the following pemilt- and
enforcement related activities:
• Maintaining current FSE information, such as mailing and
service address, names of chief operating officer and contact,
telephone and facsimile numbers, number of employees,
operating hours,etc.
• Maintaining a database for permit-related information such as
GIS information, grease interceptor location, original date of
permit issuance,per nit expiration date,etc.
• Maintaining a database for storing inspection findings and
cracking Corrective Action Notices.
• Generating Notices of Violation,when applicable.
• Tracking self-monitoring requirements, generating reminder
letters to conduct self-monitoring, generating reminder letters
to submit self-monitoring reports, and generating self-
monitoring Corrective Action Notices.
Tracking all permit renewal applications and generation of new
and renewed pe rnits.
0 Tracking all submittal requirements such as progress reports,
Compliance Schedule Agreement submittals, permit condition
requirements,and any pertinent requirements.
• Generating reports such as compliance histories.

7 COMPLIANCE SCREENING
Now vzdAvom ti Z atpa4:u4
OCSD's compliance screening procedures involve the review of all available
information generated by monitoring activities in comparison with the
FSE's permit requirements,to soft out noncompliant dischargers.This step
is designed primarily to identify apparent violations and subsequently
determine the appropriate response in the next steps.
OCSD established standard compliance screening procedures for violations
pertaining to perm ing, grease interceptor maintenance requirements,
BMP implementation and reporting requirements,administrative mandates,
ordinance, and special permit conditions. With the aid of OCSD's data
management system, standand procedures are followed in systematically
identifying all violations and subsequently notifying FSHs of the violations.
The bulk of the compliance screening process deals with the identification
of grease interceptor maintenance requirement violations (25%rule),failure
to implement mandatory BMPs, reporting violations, and compliance
schedule violations. In an effort to conduct the compliance screening
process efficiently, OCSD developed computer programs for automatic
identification of these violations. Not only will the automated process
assist in developing a consistent response,it will also reduce the manpower
required to conduct the compliance screening process. The preliminary
review and evaluation are handled by the administrative support utilizing
the computerized data management system. Computerized compliance
screening applications include;
• Screening violations for failure to comply with the grease interceptor
maintenance requirements (25%Wile)and failure to implement required
BMPs;
• Screening for reporting violations based on computerized tracking for
all report subrnittal requirements;and
• Screening for violation of administrative mandates based on
computerized tracking of all administrative mandate requirements.
Because timing is an important element that needs to be considered when
conducting compliance screening, OCSD established procedures to review
the information on a "rolling" (as received) basis. The data are screened as
soon as they are received, which triggers generation of a Notice of
Violation when applicable,as an initial enforcement action.
OCSD has developed procedures for careful examination of monitoring
data to accurately determine the compliance status of each FSH. The
PV ao
FOG Source control Program and Enforcement Management System
following describes specifically what OCSD does to screen different types
of violations:
7.1 Screening for Violations Pertaining to Unauthorized
Discharges
7.1.1 Discharging Without a Pemtit
During the course of routine inspections of perrrtitted FSEs,
OCSD's inspectors conduct searches for FSEs discharging to the
sewer without a permit. OCSD identifies non-permitted FSES by:
• Working with the City of Tustin's Community Development
Department-Building Division,to identify new construction or
major renovation of FSEs exceeding$50,000.
• Obtaining and reviewing, on a periodic basis, a fist of FSEs
from the City of Tustin's Business License Division to identify
new FSEs.
Reviewing the list of FSEs inspected by the Orange County
Health Care Agency(OCHCA) on an annual basis.
Upon identification of an unpemtitted FSE, OCSD issues a Notice
to Apply for Permit; provides a Permit Application; and specifies
the deadline when to submit the application.
7.1.2 Failure to Inform Change of Ownership
This violation is usually detected by the inspectors in the course of
their routine inspection as they gather information from the contact.
Upon identification of the violation,the inspector issues a Notice to
Apply and provides a pemvt application. The inspector specifies the
deadline to submit the application and is responsible for the follow-
up.
7.1.3 Discharging with an Expired Permit
This violation is usually determined through the permit renewal
process with the aid of a computer. On a monthly basis, a list of
FSEs whose permits are about to expire is generated by the
computer. A designated person is responsible for following up the
fiction renewal process and identifying noncompliant FSEs. Proper
notification and sufficient time is provided to the FSE to ensure that
the permit is renewed prior to expiration.
P.y 31
FOG Source Control Program and Enforcement Management System
7.1.4 Discharging with Suspended Permit or Discharging with
Revoked Permit
Since these violations do not happen frequently, FSEs with
Suspended Permits or Revoked Permits are closely monitored and
tracked down by inspectors through actual inspection of the FSE's
facility.
7.2 Screening for Noncompliance with the BMP
Implementation Requirements
7.2.1 Failure to Implement Required BMPs
This noncompliance is detected during submission of BMP Self-
Monitoring Reports and during routine onsite inspections. The Self
MonitoringReports indicate BMPs which are not implemented.
Information provided by FSE is entered in the computer which
automatically detects noncompliance and generates the Corrective
Action Notice. Further tmcking of the Corrective Action Notice
issued is integrated in the computer program which requires
subsequent input to indicate whether the FSE has met compliance or
a Notice of Violation needs to be issued.This noncompliance is also
detected during onsite inspection for which a Corrective Action
Notice is issued. Further tracking of the Corrective Action Notice is
also done by the computer which requires subsequent inpuS to
indicate whether the FSE has met compliance or a Notice of
Violation needs to he issued, after conducting a Follow-up
Inspection and Compliance Verification.
7.2.2 Failure to Keep Required Records for Implementing
BMPs
Record keeping, such as training logs, yellow grease disposal logs,
etc., is part of die BMP implementation requirement.
Noncompliance with this requirement is detected during onsite
inspection for which a Corrective Action Notice is issued. Further
tracking of the Corrective Action Notice is done by the computer
which requires subsequent input, to indicate whether the FSE has
met compliance or a Notice of Violation needs to be issued, after
conducting a Follow-up Inspection and Compliance Verification.
PV 32
FOG Source control Program and Enforcement Management System
7.3 Screening for Violations of Grease Interceptor
Maintenance Requirements
7.3.1 Violation of the 25%Rule
During inspection of grease interceptors, the depths of the
accumulated solids and FOG are measured to determine compliance
with the 25%rule.If noncompliance is detected,a Corrective Action
Notice is immediately issued requiring the FSE to immediately,pump
the full contents of the interceptor within a specked number of days.
A Follow-up Inspection and Compliance Verification is conducted
to determine if FSE has met compliance. Computer trucking for
these events will determine if a Notice of Violation needs to be
issued.
7.3.2 Failure to Maintain Pans of the Grease Interceptor in
Proper Operating Condition
As part of the grease interceptor inspection, the internal putts are
inspected to ensure that they are properly maintained and in good
operating condition. When a problem is detected, a Corrective
Action Notice is immediately issued requiring the FSE to
immediately fix the problem within a specified number of days.
Further tracking of the Corrective Action Notice is done by the
computer, which requires subsequent input, to indicate whether the
FSE has met compliance or a Notice of Violation needs to be issued,
after conducting a Follow-up Inspection and Compliance
Verification.
7.3.3 Failure to Keep Required Records for Grease Interceptor
Maintenance
Record-keeping, such as maintenance records and wastehauling
records, is put of the grease interceptor maintenance requirement.
Noncompliance with this requirement is detected during onsite
inspection for which a Corrective Action Notice is issued. Further
tracking of the Corrective Action Notice is done by the computer
which requires subsequent input, to indicate whether the FSE has
met compliance or a Notice of Violation needs to be issued, after
conducting a Follow-up Inspection and Compliance Verification.
PV 33
FOG Source Control Program and Enforcement Management System
7.4 Screening for Violations of Reporting
Requirements
7.4.1 Delinquent Reports
Most reporting violations are caused by delinquent reporting. For
purposes of compliance screening, OCSD has established a
computerized tracking system for all reporting requirements. When
requirements for a specific FSE are established, the information is
entered into the computer with a brief description of the
requirement and when the requirement is due. Upon submission,
the computer database is also updated to indicate that the report has
been received. On a weekly,basis, the computer generates a report
which summarizes all upcoming reports due and overdue reports.
Not only does this facilitate tracking and follow-up, but it also
provides compliance screening for FSEs who fail to satisfy the
repotting requitement Upcoming requirements which are soon due
are flagged by the computer; subsequently, OCSD sends reminders
to FSEs to inform them of the upcoming due date as a preventive
measure for reporting violation occurrences. Such reminders have
proven to be beneficial in preventing this type of violation.
7.4.2 Inaccurate Reports
Upon submission of required reports, the information is initially
screened by clerical staff for completeness and then reviewed by
technical staff for technical content. Compliance screening for
inaccurate reports is determined during this process.
7.5 Screening for Violations of Administrative
Mandates
All requirements of administrative mandates such as Compliance
Schedule Agreements are monitored tbmugh the computer for
compliance. When requirements are established, the information is
entered into the computer with the corresponding due date for
tracking purposes. Similarly, dte computer is updated when the
requirements are satisfied. Compliance screening is accomplished
through reports generated by the computer which summarize
overdue requirements. As a preventive measure, OCSD sends
reminders to FSE. to into. them of the requirements with
upcoming due dates.

FOG Source Control Program and Enforcement Management System
7.6 Violations of Ordinance and Special Permit
Conditions Detected During Inspections
Compliance screening for violations occurring at the FSH's facility is
determined by inspectors during the course of routine on nonmoutine
inspections. When noncompliance is detected, a Corrective Action
Notice is immediately issued requiring the FSE to immediately
correct the problem within a specified number of days. Further
tracking of the Corrective Action Notice is done by the computer
which requites subsequent input, to indicate whether the FSE has
met compliance or a Notice of Violation needs to be issued, after
conducting a Follow-up Inspection and Compliance Verification.

8 IMPLEMENTING ENFORCEMENT
ACTIONS
Eqow'"'" ot*0040 "AjAuc
OCSD's first consideration in developing enforcement responses was to
anticipate as many types and patterns of violations as possible that are likely
to be encountered, as discussed in Section 7. This way, specific
enforcement responses may be formulated. The violations and
discrepancies that are identified during the compliance screening process
are reviewed to evaluate the type of enforcement response needed.
Guidelines are established to:
• Provide guidance in determining procedures to be followed to identify,
document and respond to the violations;
• Provide guidance in selecting initial and follow-up enforcement actions;
• Establish staff responsibilities for implementing enforcement actions;
and
• Designate suggested time frames for implementing enforcement
actions.
OCSD's second consideration was to provide a range of enforcement
options that can be used to respond to violations. OCSD uses a
comprehensive range of enforcement mechanisms within the legal
authorization granted by the Clean Water Act, the state legislature, and
OCSD's FOG Ordinance.

Pyp 36
FOG Source Control Program and Enforcement Management System
8.1 Enforcement Responses
The following describes the range of enforcement options used by
OCSD in responding to different types of violations:
8.1.1 Connective Action Notice (CAN)
Corrective Action Notices are informal notices used to initially
address and correct noncompliance to provide the FSE with an
opportunity to correct the problem before issuance of a formal
Notice of Violation with the associated Noncompliance Fees. The
Corrective Action Notice specifies the problem that need to be
corrected and a due date for completion. After the required
completion date, OCSD conducts a Compliance Follow-up
Inspection and Verification to determine if FSE is in full compliance.
Corrective Action Notices are tracked to ensure that appropriate
follow-up is consistently conducted.
8.1.2 Notices of Violation (NOV)
When a Corrective Action Notice for noncompliance with permit
conditions or Ordinance provisions is issued,a Follow-up Inspection
and Compliance Verification follows to Bete nine if FSE has met
compliance. When the FSE is found to have failed to correct the
problem, A Notice of Violation is issued together with a
Noncompliance Fee.The NOV describes the type of violation, and
specifies that corrective actions must be taken to preclude escalated
enforcement actions.
8.1.3 Noncompliance Fees
When a Notice of Violation is issued, a Noncompliance Fee is
typically imposed on the FSE. The fee recovers OCSD's
administrative and field costs in dealing with the noncompliance.
8.1.4 Compliance Follow-Up Inspection and Verification
Following issuance of a Corrective Action Notice as a result of
noncompliance, OCSD conducts a compliance follow-up inspection
to determine whether the FSE has implemented corrective measures
and has resolved problems. Based on this inspection, a Notice of
Violation is issued if the FSE is found to have failed to correct the
problem or the enforcement action is terminated if the
noncompliance problem has been resolved.
PV 37
FOG Source Control Program and Enforcement Management System
8.1.5 Compliance Audit
Compliance Audits are conducted by OCSD staff for FSEs who
have demonstrated continued or repeated violations. Compliance
Audits are performed in order to investigate the cause of the
recurring violations, and to assess the level of corrective measures
and enforcement actions needed to fully resolve the noncompliance
problem. A Compliance Audit is usually followed by a Compliance
Meeting.
8.1.6 Compliance Meetings
Compliance Meetings are held when an FSE has demonstrated
continued or repeated violations. A Compliance Meeting is usually
held after a Compliance Audit has been conducted. The meeting is
held at OCSD's administration office, and attendance by the
representatives of the FSE is mandatory. During the meeting, the
results of the Compliance Audit are discussed, and a plan is
developed to establish the corrective actions to be taken by the FSE
to achieve long-term compliance.
8.1.7 Increased Grease Interceptor Pumping/Maintenance
OCSD may impose more frequent grease interceptor
pumping/maintenance requirements if an FSE has demonstrated
continued or repeated violations of the 25%Rule.
8.1.8 Order to Cease Noncompliant Discharge
When OCSD finds that the FSE has continued to discharge
wastewater in violation of OCSD's Ordinance or the provisions of
its wastewater discharge permit, an Order to Cease Noncompliant
Discharge may be issued to stop noncompliant discharge.The Order
also notifies the FSE of subsequent enforcement actions that could
be taken should violations continue.
8.1.9 Compliance Schedule Agreement
Upon a determination that an FSE is in noncompliance with the
terms, conditions or limitations specified in its permit or any
provision of OCSD's Ordinance, and that it needs to construct
and/or acquire and install pretreatment equipment, OCSD may
require the FSE to enter into a Compliance Schedule Agreement.
The Compliance Schedule Agreement contains requirements and
conditions by which an FSE must operate during its term and
provides specific dates for construction and/or acquisition and
Prat 38
FOG Source Control Program and Enforcement Management System
installation of requited equipment or implementation of corrective
actions.
8.I.10Administrative Complaint/Administrative Fines
Pursuant to the authority of California Government Code Sections
54740.5 and 54740.6,OCSD may issue an Administrative Complaint
to any FSE that violates any provision of OCSD's Ordinance; any
pernit condition, prohibition, or effluent limit; or any suspension,
revocation or other order. The Administrative Complaint describes
the violation, the provision of the law authorizing civil liability to be
imposed,and the proposed administrative fine.
The Adrnhtistmtive Complaint also provides notification of the date
and location of an administrative hearing regarding the complaint.
The hearing is held within 60 days after the complaint is transmitted.
The hearing is conducted by a staff member designated by OCSD's
General Manager. The FSE may waive its right to a hearing, in
which case the hearing is not conducted. At the heating,the FSE is
given an opportunity to respond to the allegations set forth in the
Administrative Complaint by presenting written or oral evidence.
After the conclusion of the heating, the heating officer submits a
written report to the General Manager setting forth a statement of
facts found to be true, a detemdnation of the issues presented,
conclusions and a recommendation. Should the General Manager
find that grounds exist for assessment of an administrative fine, his
decision and order are issued in writing within 30 days after the
conclusion of the hearing. The written decision is then constituted
to the FSE.
Administrative fines may be assessed as follows:
• In an amount not to exceed two thousand ($2,000.00) for each
day for failing or refusing to finish technical or monitoring
reports;
• In an amount not to exceed three thousand dollars ($3,000.00)
for each day for failing or refusing to timely comply with any
compliance schedules established by OCSD;
• In an amount not to, exceed five thousand dollars ($5,000.00)
per violation for each day of discharge in violation of any waste
discharge limit, permit condition, or requirement issued,
reissued,or adopted by OCSD;
• In any amount not to exceed ten dollars ($10.00) per gallon for
discharges in violation of any suspension,revocation,cease and
desist order or other orders, or prohibition issued, reissued, or
adopted by OCSD.
In determining the proposed administrative penalty, OCSD takes
into consideration such factors as environmental or physical harm to
PV 39
FOG Source Caroni Program and Enforcement Management System
the POTW, the good faith efforts of the FSE once it became aware
of the problem,the magnitude and frequency of violations,the FSE's
history of noncompliance,and economic benefit.
8.1.11 Revocation of Waiver from Grease Interceptor Installation
Upon determination that an FSE is a major FOG contributor, any
existing Waiver from Grease Interceptor Installation may be revoked.
Upon revocation of the waiver, the grease interceptor installation
requirement is included in the permit and immediately implemented.
8.1.12 Revocation of Variance from Grease Interceptor
Requirements
Upon determination by OCSD that the Variance from Grease
Interceptor Requirements is no longer appropriate, OCSD may
revoke the variance and pursue installation of a standard grease
interceptor.
8.1.13 Permit Suspension
A perrnit may be suspended when it is determined that an FSE has:
• Failed to comply with the terms and conditions of a
Compliance Schedule Agreement.
• Knowingly provided a false statement, representation, record,
repog or other document to OCSD.
• Refused to provide records,reports,plans,or other documents
required by OCSD to deterudire permit terms, conditions,

8.1.15 Order to Terminate Discharge
An Order to Terminate Discharge may be used to require an FSE to
physically terminate its sewerage service if the ESE has failed to
comply with an Emergency Suspension Order or Permit Revocation
Order,or if an FSE without a valid permit fails to immediately cease
and desist discharge.
8.1.16 Emergency Suspension Order
OCSD may suspend sewerage service by order of the General
Manager when it is determined that a suspension is necessary in
order to stop an actual or impending discharge which presents or
may present an imminent or substantial endangerment to the health
and welfare of persons, or to the environment, or may cause
interference with OCSD's sewerage facilities or operations, or may
cause OCSD to violate any Local, State or Federal Law Regulation.
Any discharger notified of and subject to an Emergency Suspension
Order is required to immediately cease and desist the discharge of all
wastewater to the sewerage system. Within five days of the issuance
of an Emergency Suspension Order, the General Manager holds a
hearing to provide the FSE with an opportunity to provide
information in opposition to the order. The General Manager then
issues a written decision within two business days following the
hearing,and the decision is transmitted to the FSE.
8.1.17 Civil Penalties (judicial)
pursuant to the authority of California Government Code Sections
54739 - 54740 and the Clean Water Act, 33 U.S.C. Section 1251 et
seq., any person who violates any provision of OCSD's Ordinance,
or any permit condition, prohibition or effluent limit is potentially
Gable civilly up to $25,000.00 per violation for each day in which
such violation occurs. This action is initiated by OCSD's General
Counsel, upon order of the General Manager, by petoonhrg the
Superior Court to impose,assess and recover such penalties,or such
PV 42
FOG Source Control Program and Enforcement Management System
other penalties as OCSD may impose, assess, and recover pursuant
to Federal and/or State legislative authorization.
8.1.18 Injunction
OCSD may petition the Superior Court for the issuance of a
preliminary of pertnanent injunction, or both, to restrain or prevent
continued or threatened violations of the Ordinance, an FSE's
permit,or any Federal Pretreatment Standard or requirement.
8.1.19 Physical Termination of Service
OCSD may physically terminate sewerage service to any property
pursuant to the terms of any order of emergency suspension or
revocation of a permit or upon the failure of a person not holding a
valid dischuge permit to immediately cease discharge,whether direct
or indirect,to OCSD's sewerage facilities.
8.1.20Criminal Penalties
Any person who violates OCSD's Ordinance is guilty of committing
a misdemeanor, and if convicted, is punishable by a fine up to
11,000.00, or imprisonment up to 30 days, or both. Each violation
and each day of violation may constitute a separate violation of the
Ordinance.
8.1.21 Financial Security
FSEs subject to enforcement or collection proceedings may be
required to provide financial security to guarantee performance or to
pre-pay charges before permission is granted to discharge to the
sewer.
8.2 Criteria for Determining Appropriate Enforcement
Actions
After identifying various types of violations and establishing a range
of available enforcement options, the specific enforcement response
most be selected. To ensure that the enforcement response selected
is appropriate in relation to the seriousness of the violation, the
following criteria are utilized:
• Magnitude of Violation
• Duration and Frequency of Violation
PV 43
FOG Source Control Program and Enforcement Management System
• Effect of Violation on Public Health and the Environment
• Effect of Violation on OCSD's Workers and Sewerage System
• Compliance Hammy y of the FSE
• Good Faith Efforts of the FSE to Eliminate Compliance
8.2.1 Magnitude of Violation
Some violations of an isolated or insignificant nature may be dealt
with by an informal enforcement action such as a reminder letter,
Corrective Action Notice or the issuance of a Notice of Violation.
However,violations of a significant nature,even a single occurrence,
can threaten the public health and the environment, or damage
OCSD's sewerage system. For this reason, the magnitude of
violation is an important factor in determining the appropriate level
of response.
8.2.2 Duration and/or Frequency of Violation
Regardless of the magnitude, the duration and/or frequency of
violation most be considered in determining an enforcement
response. All else being equal, violations which continue over
extended periods of time are subject to mote escalated levels of
response.
8.2.3 Effect of Violation on Public Health and the Environment
The actual or potential effect of a violation on public health and the
environment is a significant factor in determining the level of
response. In situations where there is an imminent threat to public
health and the environment, OCSD may immediately suspend
sewerage service. The level of response is related to the impact of
the violation, and is also devised to recover any costs incurred by
OCSD. For example, if the violation has resulted in SSO to a
penalty imposed on OCSD, the FSE would be responsible for the
penalty amount.
8.2.4 Effect of Violation on OCSD's Workers and Sewerage
System
Some discharge violations may result in adverse effects on OCSD's
workers and/or sewerage system. Adverse effects on the sewerage
system can include harm to equipment, processes, or operations;
contamination of wastewater or biosolids; and damage or
obstruction to the collection system. The level of response is related
to the impact of the violation, and is also devised to recover any
costs incurred by OCSD as a result of the violation.

FOG Source Control Program and Enforcement Management System
8.2.5 Compliance History of the FSE
The compliance history of the FSE must be considered in
determining the appropriate level of response to a violation. In
addition, the various aspects of the compliance history should be
taken into consideration including the states of the FSE's
preureatment equipment, operation and maintenance efforts, waste
cauterization efforts,etc.
8.2.6 Good Faith Efforts of the FSE to Eliminate
Noncompliance
The good faith efforts of an FSE, once it is aware of a violation,
plays a role in determining the appropriate level of response to a
violation. Good faith efforts must be compared against the criteria
provided in the Clean Water Act-.
"The Act requires industry to take extraordinary efforts if the vital
and ambitious goals of the Congress are to be met This means that
business-as-usual is not enough. Prompt, vigorous, and in many
cases, expensive pollution control measures must be initiated and
completed as promptly as possible. In assessing the good faith of a
discharger, the discharger is to be judged against these criteria.
Moreover,it is an established principle,which applies to this act,that
administrative and judicial review are sought on the discharger's own
time."

PURPOSE The purpose of the Fats, Oils, and Grease (FOG) Control Program is to prevent
blockages of the sanitary sewer lines that can cause sanitary sewer overflows
(SSOs) by establishing control mechanisms that will establish regulations and
policies for the disposal of FOG from Food Service Establishments (FSEs). The
control mechanisms will comprise of the FOG Ordinance (Ordinance) and FOG
Wastewater Discharge Permit (permit), which shall define general prohibitions and
restrictions on discharges, facilities requirements, administrative requirements,
procedures for recovering costs associated with FOG discharges and blockages,
and enforcement tools for implementing the program.
In addition to establishing control mechanisms, the FOG Control Program will also
include an enforcement management system to address the fundamental
requirements necessary to regulate FSEs; obtain and evaluate information on FSE
compliance; identify violations;select appropriate enforcement action; establish time
frames for implementation; and resolve noncompliance in a timely, fair and
consistent manner.
The discharge of FOG to the sewer system from FSEs will be effectively controlled
through the FOG Control Program by:
Administering an extensive permitting program to regulate wastewater
discharges from FSEs;
Tracking compliance through inspection of FSEs,reviewing Kitchen Best
Management Practices(BMPs)and Grease Interceptor Maintenance Practices,
and monitoring wastewater discharges;
Evaluating and screening the results of inspection and reports to identify
violations;
Consistently responding to all types of violations to ensure long-term
compliance; and
Requiring FSEs,when applicable,to pretreat wastewater to reduce FOG prior
to discharge to the sewer system.
FOG Control Program 1
BASIS FOR Pursuing an Equitable FOG Control Program
DEVELOPING FOG
CONTROL PROGRAM A good FOG Control Program should consistently succeed in keeping FOG
discharges below acceptable levels to protect wastewater collection systems from
Gagging and causing sanitary system overflows (SSOs). Since the problem is
caused significantly by FSEs discharging FOG, FSEs share a major responsibility
for the consequences of their FOG discharges.
It is OCSD's objective to develop and implement a FOG Control Program that is
equitable by:
Requiring all FSEs to reduce the level of their FOG discharge through
implementation of Best Management Practices (BMPs) and installation of
appropriate/adequate grease interceptor/FOG control device, among other
requirements necessary for an effective FOG control
Establishing specific permit requirements for reducing FOG discharges by
considering the quantity of FOG generated by the FSE and its potential impact
to the collection system; establishing requirements that are effective to achieve
the desired environmental results while considering costs incurred by FSEs,
considering requirements with sound technical basis; establishing practical
requirements tailored individually to each FSE based on established criteria
versus a"one size fits all"set of requirements
Establishing basic user fees and any additional user fees that may be imposed
for discharges above acceptable levels to recover costs of additional
maintenance required beyond normal; imposing mitigation fees for FSEs where
installation of adequate grease interceptor/FOG control device is not feasible
Recovering cost of FOG Control Program, which includes inspections,
sampling, program administration and maintenance,educational outreach,etc.
Implementing a FOG Control Program that addresses all FSEs that are sources
of FOG and is consistent among all FSEs.
Sewer blockages are largely dependent on the quantity of FOG being discharged
from FSEs, but are also dependent on other factors such as the size of the sewer
line, pipe material, number of dischargers to the line, type of dischargers,
topography (slope), age and condition of the sewer lines, etc. Sewer conditions
contributing to blockages can be corrected by the sewer agency; however, any
capital improvement will take a longer time to implement. Although more frequent
sewer cleaning and maintenance is one of the solutions, a balance between the
frequency of cleaning and the public cost involved must also be maintained. In the
interest of protecting public health, the immediate burden is placed on significant
FOG dischargers (FSEs)to control and reduce their FOG discharges in conjunction
with a practical sewer cleaning and maintenance schedule by the sewer agency,
while capital improvements of the collections facilities are undertaken.
FOG Control Program 2
FOG Control Essentials
There are two essential elements for effectively controlling the discharge of
FOG:
Pretreatment through installation, operation, and maintenance of a properly
designed and adequately sized grease interceptor. The use of a property
maintained grease interceptor has been shown to be the most effective
conventional FOG control technology. However, because of space restrictions
and/or cost-prohibitive retrofits for existing FSEs, its implementation becomes a
complicated issue. While other FOG control devices may be used when the
installation of a grease interceptor is not feasible, an evaluation must be
conducted to ensure that its efficacy is, at least, equivalent to that of a
grease interceptor.
Implementation of Best Management Practices (BMPs). BMPs are practical
measures that when implemented will significantly reduce the quantities of
FOG released from FSEs. When practiced consistently, BMPs help reduce
FOG loading on the grease interceptor/FOG control device. As a result, the
performance of the grease interceptor/FOG control device is optimized and
improved, with its maintenance frequency reduced, as well. BMPS include
proper grease disposal and handling and proper kitchen practices for
minimizing the discharge of FOG at the source.
OCSD will implement the above as basic general requirements, among other
requirements that will facilitate enforcement of these essentials. When
appropriate, deviation from the pretreatment requirement will be considered, to
apply practicality while maintaining consistency.
Considerations for Developing OCSD's FOG Control Program
OCSD's long-term FOG Control Program will consist of full implementation of
the essential requirements as discussed above to all new and existing FSEs.
Although it is ideal to require all FSEs to install adequate grease interceptors or
equivalent FOG control devices, considerations should be made for existing
FSEs. Existing FSEs may have not been required to install an approved grease
interceptor when they first began operations, and therefore, it is anticipated that
retrofitting problems will be encountered. Because of this, it is an extremely
difficult and complex issue to initially deal with all dischargers on an equitable
and consistent basis and, at the same time, immediately accomplish the ideal
environmental improvement required. Clearly, there is a need for an interim
program that will evolve and mature towards the ideal goal. Initially, this will
involve a compromise between approaching the desired environmental results
and impending priorities, while being Flexible and practical in implementing the
FOG Control Program 3
immediate requirements for controlling significant FOG discharges.
OCSD will implement an interim FOG Control Program, which will occur during the
first three years of its inception. During this period, existing F$Es that meet
established criteria may be allowed to operate without a grease interceptor or
equivalent FOG control device. This is a delay in implementation (conditional stay)
to allow flexibility for existing FSEs to plan and schedule the required retrofit within a
three-year period. The interim program will focus particularly on the implementation
of requirements that will result in the most significant environmental improvements,
gradually maturing and progressing towards the ideal (long-term) program to
achieve the desired environmental results. Public costs will be incurred for high
frequency cleaning of the local sewers until the FOG control devices are installed by
FSEs.
Practical Considerations for Establishing Requirements for
FOG Control: Balancing Cost and Benefits
The interim FOG Control Program policies to be developed should facilitate the
maximum beneficial public use of the sewer system while at the same time
preventing blockages of the sewer system resulting from discharges of FOG. The
primary and bottom line concern for all FSEs is the cost of installing an effective
FOG control device and the cost associated with its operation and maintenance.
While it is ideal for every FSE to have an adequate grease interceptor or equivalent
FOG control device, it is important to weigh the costs and the benefits. This is
certainly a major consideration specifically for existing FSEs that were not required
to install an approved grease interceptor or FOG control device when they first
began operations, but now may be subjected to cost-prohibitive retrofits.
Current FOG pretreatment technology typically takes the form of grease traps or
grease interceptors. The grease trap is a smaller grease handling device found in
the kitchen area of the FSE, while a grease interceptor is usually a large, in-ground,
usually concrete, tankage found outside the facility. Due to their small size, grease
traps need to be emptied more often than grease interceptors to be effective.
Grease traps have very limited effect and should,therefore, be used to reduce FOG
loading on grease interceptors. A properly designed grease interceptor is a proven
and effective FOG collection device when properly maintained and is considered
the Best Conventional Technology (BCT) for FOG control. For this reason, the
installation of a grease interceptor is an ideal requirement for all FSEs to minimize
FOG discharges to the sewer. The cost to purchase and install a medium-sized
interceptor(1500 gallons)for a new FSE is approximately$8,000;for a retrofit in an
existing FSE,the cost ranges from$10,000 to$15,000.
In maintaining a balance between cost and benefit, the ideal requirement for all
FSEs to have an adequate FOG separation and removal device in the form of a
grease interceptor is a long-term goal, and will occur after the first three years from
FOG Control Progmm 4
the initial implementation of the program. Therefore,the initial thrust of the program
should focus on prioritization and identification of FSEs for which the full
requirements for a grease interceptor will be implemented. Immediate
implementation of a "one size fits all" requirement for installation of grease
interceptors is impractical; therefore, the extent of requirements to be implemented
should vary for each FSE based on a practical approach that considers cost, and
benefit. Immediate implementation of the grease interceptor requirement for existing
FSEs that have significant impacts on sewer blockages may entail a high cost but
the environmental benefits derived are significant. Delaying this requirement for
existing FSEs that have considerably low impact will be a lesser priority and will
allow FSEs to comply within a reasonable amount of time.
In developing the FOG Control Program, the following considerations are taken into
account and serve as the basis for developing policies.
Requirements for Installation of Grease Interceptors
Existing FSEs
For existing FSEs, the initial approach should consist of prioritization to require full
installation of adequate grease interceptors for those facilities that are discharging
to sewer lines known to be the source of SSOs or sewer lines where frequent
cleaning is required.This is a"site specific prioritization"based on specific locations
where the sewer lines have been identified as "hot spots". Because there are
potentials for developing new hot spots, a preventive approach is also necessary.
The approach should not be restricted to site specific prioritization but should also
be extended to prioritization based on the amount or quantity of FOG generation
from any ESE, as indicated by the nature and magnitude of the operation. Based
on this method of prioritization, the cost impact for those FSEs that are affected is
balanced by the apparent immediate benefit of preventing blockages and sewer
spills where it is a real concern.
Conditional waivers to install grease interceptors may be granted to FSEs that are
able to demonstrate that their FOG discharge is insignificant and has no impact to
the sewer system. This conditional waiver may also be granted to existing FSEs
during the three-year period of conditional stay. A conditional variance to allow
alternative pretreatment technology in lieu of a grease interceptor, but equivalent in
performance and effectiveness, may also be granted to FSEs demonstrating that
the installation of a grease interceptor is not feasible. When a conditional variance
cannot be granted, a Waiver with a Grease Disposal Mitigation Fee may be allowed.
The fee will be used to recover the additional cost of maintenance and cleaning
associated with the elevated FOG discharge due to the FSE's inability to install the
required grease interceptor or equivalent FOG control device. The Grease Disposal
Mitigation Fee should be established such that FSEs do not get an economic
advantage for opting to pay the mitigation fee rather than installing the grease
interceptor.Therefore, it should, at a minimum, be equivalent to the cost of installing
FOG Control Program 5
a new grease interceptor and associated costs for cleaning and maintenance.
New FSEs
For new FSEs, it is expected that the full requirement to install a grease interceptor
will be implemented, since there is a full opportunity to plan for the new installation
with the cost component being part of the facility's initial capital investment.
Because FSEs conducting a major remodeling have a similar opportunity, the same
requirement for new FSEs should be implemented. Details of the criteria for defining
remodeling should be addressed by the Ordinance.
Requirements for Implementation of BMPs
In addition to pretreatment, another basic component of the FOG control program is
the application of BMPs to control generation of FOG from the source. At a
minimum, all FSEs should be required to implement enforceable BMPs.Acceptable
BMPs should be defined in the policy.
Regulatory Considerations
Use of Numerical Limits for Controlling FOG Discharge
Numerical effluent limits have been used traditionally as a tool for monitoring
discharges for most of the pollutants. When federal limits have not been defned,
local limits that are technically based are developed. In the case of FOG where no
federal limit has been defined, a local limit is necessary. However, because of
difficulties associated in establishing a technically based limit for FOG at this time,
alternative methods for controlling FOG discharges that are also effective will be
adopted until such time that a technically based FOG limit can be established. As
discussed in the following sections, OCSD will implement alternative methods for
monitoring FOG discharges from FSEs that will primarily focus on establishing
performance standards, action levels as indicated by the depth of solids/FOG build-
up in the existing interceptor, and procedures for visual inspection of FOG build-up
through CCTV.
Use of Performance Standards for Regulating FSEs
1. BMP Performance Standards - The ability of FSEs to consistently implement
BMPs is an important aspect of the FOG control program. The effectiveness of
the efforts of FSEs to reduce their FOG discharges could have been easily
determined if the actual discharge level can be compared to an established
numerical limit (pretreatment standard). In the absence of a FOG numerical
FOG Control Progrem 6
limit, however, establishing performance standards based on consistent
implementation of enforceable BMPs can be utilized. This means that
compliance evaluations will be based on the FSEs' ability to meet established
performance standards for consistently implementing BMPs. As an example,
specific minimum BMPs will be required for each FSE,as specified in its permit,
which will be enforced. OCSD will monitor FSEs' compliance by requiring
periodic submittal of BMP implementation status reports (signed by the
responsible officer under penalty of perjury)and verifying submitted information
through inspections. Depending on available resources, OCSD will have the
flexibility to conduct thorough verification or spot checking of BMPs.Appropriate
enforcement procedures will be implemented when FSEs fail to comply with the
requirement.
2. Maintenance Performance Standards— Like the BMP Performance Standards,
establishing Performance Standards for ensuring proper maintenance of the
grease interceptor/FOG control device is also important. This ensures that
FSEs adhere to the established maintenance schedule. Compliance can be
monitored by implementing a notification requirement whenever maintenance is
performed in accordance with a predetermined schedule (performance
standard). This information may also be verified through wastehaulers. Notice
of Violations may be issued when an FSE fails to comply with the required
maintenance schedule and/or notification requirement.
Use of Grease Interceptor Liquid Depth as an Action Level for
Controlling FOG Pass-through
For FSEs with grease interceptors, an alternative indicator that can be used to
evaluate compliance with the required pretreatment equipment maintenance is by
measuring the level of solids and FOG accumulation in the grease interceptors.
Excessive levels of FOG and solids accumulation in grease interceptors diminishes
removal efficiency, eventually resulting in FOG passing through the equipment and
discharged to the sewer. Therefore, establishing an interceptor liquid depth action
level will provide another method for controlling FOG discharges. Based on a
minimum allowable liquid level established as a performance standard, compliance
monitoring and evaluation may be conducted by measuring the sludge height using
a sludge judge or an electronic height measuring device to obtain the solid-free
liquid level. It is suggested to establish the sludge height performance standard
based on the 25% rule which requires that grease interceptors be pumped-in-full
when the total accumulation of surface FOG (including floating solids) and settled
solids reaches 25%of the grease interceptors overall liquid depth. This provides an
alternative method for controlling the amount of FOG discharge other than actual
measurements of effluent concentration. With the use of an interceptor liquid depth
action level, compliance can be monitored and enforcement actions, which may
include escalation of interceptor maintenance frequency, may be imposed.
FOG Control Program 7
Use of Visual Observations of FSEs'lateral for Requiring Grease
Interceptors
Visual observation of the FSE's lateral is the most accurate indicator of a facility's
impact as a result of discharging FOG at significant levels that cause sewer
blockage. This can also be used to establish action levels that would trigger the
requirement for installation of grease interceptor.While this is accurate, it entails the
use of CCTV at the public's expense to actually get a photograph or video of the
FOG accumulation in the laterals and downstream. Depending on the availability of
resources, this monitoring method can prove to be useful in controlling FOG
discharge. There are occasions, however, when a clean lateral may not necessarily
represent the absence of FOG discharge. The use of additives or discharge of
solvents that emulsify grease can camouflage a significantly high FOG discharge.
Issuance of Waiver for Interceptor Requirement During the Three-year
Conditional Stay for Existing FSEs
As discussed above, the requirement for all FSEs to have a grease interceptor is an
ideal requirement that would most likely result in the maximum removal of grease
prior to discharge to the sewer. However, based on the considerations mentioned
above for existing FSEs and the need to balance cost versus benefit, the interim
FOG control program for requiring grease interceptor will initially focus on FSEs
which have significant impact to the sewer system. This does not mean, however,
that the rest of the FSEs are exempt from the requirement. Since the long-term goal
is to eventually have all FSEs install an adequate grease interceptor, the
requirement should remain but held in abeyance through a waiver.
From the implementation standpoint, it is more effective to impose the requirements
on all pennittees right at the beginning and issue/revoke conditional waivers as
needed than do the opposite. As changes in FSE operations impacting FOG
discharge are encountered such as business expansion, waivers may be revoked.
Revocation of waivers will be driven by changes in the criteria for issuing the
waiver, in response to a more stringent requirement to further control FOG due to
continuing SSOs and imminent threat to public health. The criteria for issuing
waivers will be set under OCSD's policy and waivers issued will be reviewed for re-
issuance based on a specific frequency that will be established in the FOG Control
Policies.The criteria for waiver issuance to existing FSEs may include:
Average daily FOG discharge less than prevailing FOG action level
Location of FSE is not considered a hot spot
Satisfactory compliance with required BMPs
Compliance with all permit requirements and prohibitions
Absence of indicators that the FSE's FOG discharge has significant impact
to the sewer
FOG Control Progrem 8
Technical Considerations
Interceptor Sizing Consideration
Currently, there are different methods available for sizing grease interceptors. The
sizes will vary considerably depending on the method used. It is suggested that until
an acceptable sizing method is adopted, the use of the Uniform Plumbing Code
(UPC)formula should be used. Although this may result in a larger interceptor, it is
conservative and is universally accepted. Deriving a new formula that is technically
justified will require a considerable amount of research and study, which should
include obtaining data for the local condition. A minimum size interceptor should be
established; 750 gallons minimum volume is recommended. Interceptor sizes from
375 to 750 gallons should require the minimum volume of 750 gallons. 375 gallons
is recommended as a de minimis value for requiring interceptors; i.e., installation
requiring less than 375 gal may be exempt. When the UPC sizing calculation
exceeds 1000 gallons, the calculation should be compared with other formulas to
ensure that the interceptor is not oversized. Engineering judgment should be used
when there are large discrepancies by also considering other factors such as menu,
frequency of use of drainage fixture units, etc., to determine the final size of the
interceptor.
Determining Interceptor Cleaning Frequency
The cleaning frequency should depend upon the FSEs' type of operation and is,
therefore, expected to vary. The frequency for cleaning interceptors is affected by a
lot of factors and varies from FSE to FSE. Although frequent grease interceptor
cleaning is desirable, a balance between cost and benefit should be maintained.
Because this is an important issue for FSEs due to the cost involved, as well as for
OCSD as it affects the success of the FOG control program, it is very important to
establish a cleaning frequency requirement that is practical and effective. Therefore,
this issue must be addressed appropriately. The use of a "one size fits all" cleaning
frequency may seem very easy to manage from the regulatory standpoint, but can
be either impractical and/or cost prohibitive for some FSEs or too lax for other
FSEs. Specifying a cleaning frequency for each FSE that reflects a representative
time when cleaning is actually needed is ideal but the determination for establishing
frequency may be more involved. The following procedure will be used for
establishing required cleaning frequency:
1. Grease interceptors should be pumped out (pumped-in-full) and cleaned at a
frequency such that the combined FOG and solids accumulation does not
exceed 25%of the total liquid depth of the grease interceptor. This is to ensure
that the minimum hydraulic retention time and required available volume is
maintained to effectively intercept and retain FOG discharged to the sewer
system.
2. Grease interceptors should be pumped out and cleaned quarterly when the
FOG Control Program 9
frequency described in (1) has not been established. This standard default
cleaning frequency was established based on the most common or typical
frequency found to be effective for most FSEs. This frequency is used only for
the purpose of establishing a default cleaning frequency initially, but will be
changed accordingly to reflect a more representative frequency based on actual
data. The maintenance frequency shall be adjusted when sufficient data have
been obtained to establish an average frequency based on the requirements
described in (1) and guidelines in the FOG Control Policies. OCSD may
change the maintenance frequency at any time to reflect changes in actual
operating conditions in accordance with the FOG Control Policies. Based on the
actual generation of FOG from the FSE, the maintenance frequency may
increase or decrease.
3. FSEs may submit a request to change the maintenance frequency at any time.
The FSE has the burden of responsibility to demonstrate that the requested
change in frequency reflects actual operating conditions based on the average
FOG accumulation over time and meets the requirements described in (1), and
that it is in full compliance with the conditions of its permit and the Ordinance.
Upon determination by the FOG Control Program Manager that requested
revision is justified, the permit will be revised accordingly to reflect the change
in maintenance frequency.
4. All FSEs with a grease interceptor will be required to maintain their grease
interceptor at least every 6 months.
Routine inspection to monitor liquid depth to verify the FSE's ability to maintain
liquid depth above the action level will serve as a check whether cleaning
frequencies previously established are still applicable or need to be re-adjusted.

Existing FSEs that have reasonable potential to adversely impact the
sewer system or have sewer laterals connected to hot spots, as
determined by the FOG Control Program Manager, shall install grease
interceptors.
Existing FSEs undergoing remodeling or a change in operation as
defined in the Ordinance, or FSEs which change ownership, shall be

FOG Control Program 12
Issuance of Variance and Waivers
1. Variance from Grease Interceptor Requirements
A variance to allow alternative pretreatment technology that is, at least,
equally effective in controlling the FOG discharge in lieu of a grease
interceptor may be granted to FSEs demonstrating that it is impossible or
impracticable to install, operate or maintain a grease interceptor. The FOG
Control Program Managers determination to grant a variance will be based
upon, but not limited to, evaluation of the following conditions:
There is no adequate space for installation and/or maintenance of a grease
interceptor.
There is no adequate slope for gravity flow between kitchen plumbing
fixtures and the grease interceptor and/or between the grease interceptor
and the private collection lines or the public sewer.
The FSE can justify that the alternative pretreatment technology is
equivalent or better than a grease interceptor in controlling its FOG
discharge. In addition, the FSE must be able to demonstrate, after
installation of the proposed alternative pretreatment, its effectiveness to
control FOG discharge through downstream visual monitoring (CCTV) of
the sewer system,for at least three months, at its own expense.A Variance
may be granted if the results show no apparent accumulation of FOG in its
lateral and/or tributary downstream sewer lines.
2. Conditional Waiver from Installation of Grease Interceptor
A conditional waiver from installation of a grease interceptor may be granted for
FSEs that have been determined to have negligible FOG discharge and
insignificant impact to the sewer system. The FOG Control Program Manager's
determination to grant or revoke a conditional waiver shall be based upon, but
not limited to, evaluation of the following conditions:
Quantity of FOG discharge as measured or as indicated by the size of
FSE based on seating capacity, number of meals served menu,water
usage,etc.
Adequacy of implementation of BMPs and compliance history
Sewer size,grade, condition based on visual information(CCTV), FOG
deposition in the sewer by the FSE,and history of maintenance and
blockages/sewage spills in the receiving sewer system
FOG Control Program 13
Changes in operation that significantly affects FOG discharge
Any other condition deemed appropriate by the FOG Control Program
Manager
3. Waiver from Grease Interceptor Installation with a Grease Disposal Mitigation
Fee
For FSEs where the installation of grease interceptor is not feasible and no
equivalent alternative pretreatment can be installed, a waiver from the
grease interceptor requirement may be granted with the imposition of a
Grease Disposal Mitigation Fee as described in the Ordinance. The FOG
Control Program Manager's determination to grant the waiver with a Grease
Disposal Mitigation Fee will be based upon, but not limited to, evaluation of
the following conditions:
There is no adequate space for installation and/or maintenance of a grease
interceptor.
There is no adequate slope for gravity flow between kitchen plumbing
fixtures and the grease interceptor and/or between the grease interceptor
and the private collection lines or the public sewer.
A variance from grease interceptor installation to allow alternative
pretreatment technology cannot be granted.
4. Application for Waiver or Variance of Requirement for Grease Interceptor
An FSE may submit an application for waiver or variance from the grease
interceptor requirement to the FOG Control Program Manager. The FSE
bears the burden of demonstrating, to the FOG Control Program Manager's
satisfaction, that the installation of a grease interceptor is not feasible or
applicable. Upon determination by the FOG Control Program Manager that
reasons are sufficient to justify a variance or waiver, the permit will be
issued or revised to include the variance or waiver and relieve the FSE from
the requirement. Terms and conditions for issuance of a variance to an FSE
shall be set forth in the permit. A waiver or variance may be revoked at any
time when any of the terms and conditions for its issuance is no longer
satisfied.

Executive Summary
The Orange County Sanitation District(OCSD) is committed to providing services for its rate
payers to reliably meet our regulatory mandates and levels of service approved by the Board of
Directors. OCSD will provide these services using sustainable engineering principles that result in
the lowest responsible lifecycle cost. OCSD installs, operates, maintains, refurbishes and
disposes of assets with lifecycles measured from years to decades, so an approach which
balances short, medium and long term needs is necessary.
Asset management at OCSD has evolved into a comprehensive decision making framework that
encompasses engineering planning, design and construction of quality facilities, optimized
operation, proper maintenance, and planned refurbishment and disposal that will meet OCSD's
changing needs. For OCSD asset management is more than a project or a program. It is not just
a software tool. It is the improved decision making and action that lead to consistently meeting a
Board of Directors mandated level of service to the rate payers at the lowest Iifecycle cost.
OCSD's Asset Management Plan focuses on the long term modeling of systems to assure the
proper rate structure is in place to support sustainable operations and to prioritize condition
assessment studies based on service life and service conditions. These are important starting
points and have yielded tangible benefits in reduced risk levels and an improved capital planning
approach. The results of the long term modeling are completely dependent on the data quality of
the databases supplying information to the TeamPlan Software. Staff continues to improve the
data quality of the source systems to improve the accuracy of the long term model. The
implementation of the Maximo Computer Maintenance Management Software is an example of an
effort to improve OCSD's Asset Register. CMMS Technicians and the Asset Engineers continue to
work to update the database information including installation date, asset cost, condition and
criticality in the new system.
OCSD has tens of thousands of assets in various stages of their Iifecycles. It was recognized that
improved planning and coordination of overall OCSD activities were possible in the medium (1 -10
years)and short term (0-1 year)time frames. To improve these asset management activities
some organization structure changes were made at OCSD. The Engineering Planning Division
and Asset Management Division were consolidated to Planning activities. This has allowed
continuing and expanding the concept of making staff more accountable for specifically defined
assets and areas, which has formed the basis for the improved medium and short term
management technics.
These deliverables form the basis for the improved medium and short term management technics.
For the medium term, the asset engineers are tasked with assisting the Engineering Planning
Division with creating a fifteen year planning window for facility refurbishment or replacement.
Thus, the Engineering Planning Division is now responsible for scoping the facilities needed to
accommodate a changed level of service project elements, and preliminary scheduling of
necessary refurbishment or replacement project elements.
This medium term management is important for several reasons. By moving away from narrowly
focused projects to solve individual problems, to more comprehensive projects refurbishing entire
processes, OCSD benefits by having less operational disruption and more efficient project delivery,
better cash flow estimation, and better operations and maintenance decision making framework.
This is a huge undertaking based on the number of asset and facilities, but over time the undefined
future rehabilitation capital estimates within the fifteen year window is expected to be drastically
reduced and replaced by more specific estimated capital needs.
Orange County Sanitation District-Asset Management Plan FY 2011-12
Complementing the medium term planning are the short term efforts to coordinate maintenance
actions that can reduce OCSD risks, actively defer the larger refurbishment projects, and reduce
asset consumption rates to minimize the need for replacement of structures and conveyance
systems when projects are executed. The Planning Division asset engineers are constantly
reviewing their area scopes of work, utilizing their criticality and condition information and
engineering judgment, to identify opportunities for operational adjustments or maintenance
activities that cost effectively extend the fife of key assets which may allow for deferral of the larger
overall project. This may be a targeted equipment replacement or pipeline repair that is more
urgent than the need of the overall facility. The engineers may also identify opportunities to reduce
asset consumption through coating systems, atmosphere improvements or small structure repairs
before major damage is done. These actions can drastically reduce the cost of future projects by
preventing the need to demolish and replace entire structures, and because of this OCSD has a
division specifically tasked with providing outsourced services to provide capacity to deliver these
specialize maintenance repair services. The asset engineers provide the basic scope and cost
information to maintenance for approval through the annual budget process which help
maintenance develop comprehensive maintenance planning and supports the medium term project
scheduling. In conclusion, OCSD is building on the effective long term asset management
foundation it has been developing since 2002.
OCSD is committed to the continuous improvement of its asset management process by which it
manages its assets and facilities. This is in an effort to meet its requirement to reliably deliver its
level of service commitments. The additional resources and individual accountability for specific
areas continues to improve our capital planning, project packaging, project execution and delivery,
plant operability, and maintenance planning.
Inventory of Assets
Understanding the characteristics of all of our assets is critical to our future success. Our assets
can generally be split between two main groups: Collection System —the assets responsible for
the collection and transfer of sewage from the cities to the treatment plants, and; Treatment and
Disposal—the assets that treat the sewage and dispose of the treated effluent and by-products.
The support facilities are contained in these groupings.
The following charts present the investment history in both of these systems and the age profile of
these assets.

Orange County Sanitation District-Asset Management Plan FY 2011-12
This average age and value of the assets OCSD own is increasing steadily over time, and the
asset replacement obligation is rising, and as a consequence, OCSD needs to be planning for
decreased capital projects for capacity expansion and increased renewal expenditures in the future
relative to past expenditure levels. More focus will need to be given to ensure that appropriate
operation and maintenance strategies are being applied that consider the different ages of assets
being maintained.
Asset Valuation
The replacement valuation for all of OCSD's assets has been updated. The table below presents
the current replacement and depreciated values of OCSD's assets. The replacement value
represents the cost in December, 2012 dollars to completely rebuild all the assets to a new
condition. The depreciated value is the book value of the assets based on their age, which is a
prediction of their current condition.
The 2012 replacement value is estimated to be$6.20B. In 1998 the prediction was $2.0313, which
was based on original purchase cost. It is projected this will increase by approximately$7.1 B
when all of the existing three billion dollar Capital Improvement Program (CIP) has been captured
in OCSD's data base. The major reasons for this increase are all the new assets added to the
asset register and the increased replacement costs due to now having to performing construction
in a more urbanized Orange County than in the past.

Planned Expenditure
A computer model was utilized to produce the future expenditure projections for the Asset
Management Plan. This model was used to perform a series of calculations on information related
to the current and future OCSD assets. The following chart is the result of the modeling work
undertaken, including current and predicted future CIP projects and operations (including
maintenance), improved understanding of asset condition and asset life. The model formulas were
reviewed and updated by staff to improve the model output of information.
The flat black line in Figure E3 is the average of all the future cash flows, which represents the
average expenditure ($375M current value worth) required by OCSD for each of the next 100
years. The actual annual expenditure will vary depending of the actual work performed. With the
addition of new assets and existing aging assets the O&M costs will continue to rise. And
additional income in the future will also be required to pay back the capital that is currently being
borrowed.

Future Funding Requirements
The overall expenditure in future years will not"drop off' as dramatically as previously predicted in
the past after the current CIP winds down. This means that pressures on rates are likely to
continue more than previously anticipated in the past. Fully funding the O&M replacement and
rehabilitation costs of the assets will mean that the likely scenario for OCSD rates will necessitate
greater-than-inflation rate increases in the future.

The annual influent flow of 211 million gallons per day(mgd) comes primarily from 11 sewer sheds
within the 479-square mile service area. OCSD also receives flow from the Santa Ana Watershed
Project Authority(SAW PA), Irvine Ranch Water District(IRWD), and treats urban runoff from within
the service area.
Treated wastewater is a major reclamation source in Orange County. The Orange County Water
District(OCW D) Groundwater Replenishment System (GWRS)treats OCSD effluent to drinking
water standards for groundwater recharge and irrigation uses.
1.2 Overview of Existing System
The OCSD sewer system collects wastewater through an extensive system of gravity sewers,
pump stations and force mains, with diversions installed between trunk sewer systems.
Wastewater is treated at two treatment facilities, and an outfall system is available for ocean
disposal of treated wastewater. The treatment plants currently operate under a permit from the
Regional Water Quality Control Board, as established in National Pollutant Discharge Elimination
Systems (NPDES) that permits the discharge of treated wastewater through an ocean outfall
system to the Pacific Ocean.
The following sections briefly describe the key systems under OCSD's management.
Section 5 includes the asset system summaries for the Treatment Plants and the Outfall
System.
Trunk Sewer Systems
OCSD's service area consists of eleven trunk sewer systems that are located throughout 479-
square miles of service area. The trunk sewer systems includes 406-mile long regional interceptor
and trunk sewers, 28 miles of force mains, 15 off-site pumping facilities, and the 176-mile long
local sewer system. The trunk sewer system also includes nine interconnections (to convey flow
between main trunks) and 103 manhole diversion structures (to convey flow between sewer pipes
within a trunk system). Operationally, OCSD is maximizing the diversion of wastewater to the
Plant 1 facility in Fountain Valley to make more reclamation water available to OCW D. A portion of
the raw wastewater containing industrial waste and brine tributary to Plant No. 1 is diverted to
Plant No. 2 via a 120-inch interplant pipeline.
Treatment Plant System
OCSD has two wastewater treatment plans. Plant No. 1 is located in the City of Fountain Valley,
approximately four miles inland off the Pacific Ocean and adjacent to the Santa Ana River. Influent
wastewater entering Plant No. 1 passes through the flow metering structure, mechanical bar
screens, grit chambers and the primary clarifiers, before going to one of two air activated sludge
plants or trickling filters. The activated sludge plants consist of aeration basins and secondary
clarifiers. The trickling filters consist of a pair of trickling filters and secondary clarifiers. Up to 135
mgd of secondary effluent can be diverted to the OCWD for tertiary treatment before reuse. The
remainder of the secondary effluent flows through the pipeline to Plant No. 2 and the ocean outfall
for final disposal. Plant No. 2 is located in the City of Huntington Beach, adjacent to the Santa Ana
River and east of the Pacific Coast Highway. Untreated wastewater flow entering Plant No. 2
passes through the flow metering structure, mechanical bar screens and grit removal chambers.
14
Omnge County Sanitation District-Asset Management Plan FY 2011-12
Flow then passes through the primary clarifiers before being split between the oxygen activated
sludge secondary treatment plant or solids contract trickling filters then discharged directly to the
ocean outfall pumping and outfall system. As of December 2012, OCSD only discharges
secondary treated waters to the ocean.
Interconnections exist between Plant Nos. 1 and 2 including communications cables, Plant No. 1
effluent lines to the Ocean Ouffall Booster Station, a digester gas pipeline, and a raw wastewater
interplant pipeline.
Solids treatment at both Plant No. 1 and 2 includes in-basin thickening of primary sludge, dissolved
air floatation thickening of waste activated sludge; anaerobic sludge digestion and belt filter press
dewatering. Both plants also have facilities for odor control, and chemical addition. And the
digester gas that is created is gathered, compressed, cleaned and distributed to the Central Power
Generation System at each plant as a renewable fuel for energy generation. See Chapter 4 Asset
Management System Summaries for flow diagrams and more detailed information.
Outfall System
The ocean ouffall system includes three discharge structures. The primary ocean outfall (Ouffall
No. 2)was put in service in 1971 and is approximately 27,400 feet long including a 6,000-foot
diffuser section. The primary outfall is 120 inches in diameter and discharges treated wastewater
at a depth of approximately 200 feet some four miles offshore. The primary ouffall has a rated
capacity of 480 mgd, but varies based on tide levels. The emergency ouffall (Ouffall No. 1),
originally constructed in 1954 and modified in 1965, is approximately 7,000 feet long, including a
1,000-foot diffuser section. The emergency ouffall is 78 inches in diameter and is located at a
depth of approximately 65 feet, a mile and a half offshore. The emergency outfall has a capacity of
approximately 245 mgd. OCSD's NPDES permit specifies that this outfall can be used for
emergencies only. The current permit submitted to the EPA for approval requests the ability to use
this ouffall for maintenance purposes. The Santa Ana River emergency overflow weirs discharges
directly to the Santa Ana River, and are also limited for emergency use only. For more specific
information see Chapter 4 Asset Management System Summaries, this has flow diagrams and
descriptions of the ouffall system.

2. OCSD Levels of Service
OCSD has created an improved management system called the Strategic Framework. The
Strategic Framework is an annual business process that affirms corporate mission and vision, sets
District—wide prioritization, adjusts strategic goals, provides a disciplined budgeting process, sets
operational goals to the group operating level and holds individual units accountable for
performance. This annual process is key to developing agreed upon Levels of Service that OCSD
is committed to delivering.
The levels of service are affirmed or adjusted annually. A comprehensive Level of Service
discussion is included in the OCSD's Strategic Plan and the Budget documents. A summary of the
current levels of service are as follows:

3. Future Demand/Growth
3.1 Planning Assumptions
Historical influent flows, population projections, and estimated future per capita usage are used to
project the future average daily flow rate. Peak and minimum flow rates, and daily flow rate curves
are estimated from applying peaking factors to the average daily flow. Future solids loadings are
projected from historical solids loadings, population projections, and future treatment changes.
Through interagency agreements, OCSD receives influent from SAWPA, IRWD, and Los Angeles
County. The influent from these agencies can impact both the quantity and quality of future
influent flows. Through agreement with the Orange County Water District (OCWD), OCSD
provides treated wastewater to the GW RS and GAP facilities for reclamation. That agreement
places requirements on the quantity and quality of treated effluent provided to OCWD.
Various regulatory requirements impact CIP planning. The primary requirements involve the
discharge of treated wastewater, the release of air emissions and odors, and biosolids
management. In addition to the regulatory requirements, the OCSD Board of Directors defines
goals and policies that often exceed the regulatory requirements.
Lastly, there are emerging issues and concerns which could impact the planning of future CIP
facilities. The level of information available on these issues is not sufficient to provide clear CIP
recommendations, however, the potential impacts of these issues and concerns must be
considered.
3.2 Wastewater Flow
The flow projections presented in this section are applicable to the treatment plants only. Flow
projections and peaking factors for the collections system facilities are developed with a method
more appropriate for that system.
3.2.1 Service Area Population
Based on Orange County Projections (Center for Demographic Research [CDR], 2004), the 2005
OCSD service area population was approximately 2.5 million. Approximately 2.24 million people
reside in areas directly tributary to OCSD Plant Nos. 1 and 2. The remaining 260,000 people reside
within the area of IRWD tributary to the Michelson Water Reclamation Plant(MWRP). Table 3-1
lists projected populations for the OCSD service area between the years 2000 and 2030.
Projections from the OCSD 1999 Strategic Plan are shown for comparison.

projections were less than 3 percent lower than the Strategic Plan projections(ISPU Vol.1,pp.3-16)(OCSD,2002).
IRW D—Irvine Ranch Water District
Population increased approximately 7 percent in the OCSD service area (including the MWRP
tributary area) between 2000 and 2005. During the 25-year period between 2005 and 2030, the
population within the OCSD service area is projected to increase 13 percent. Population directly
tributary to Plant Nos. 1 and 2 is expected to increase 12 percent over the same period, whereas
population tributary to the MWRP is expected to increase 25 percent. Service area population
projections are shown in Figure 3-1.
3.2.2 Historical Influent Flow
Average daily influent flows to OCSD Plant Nos. 1 and 2 from 1992 to 2008 are shown in Figure 3-
2. Plant influent includes MWRP tributary area and Santa Ana Watershed Protection Authority
(SAWPA) discharges, as well as dry weather urban runoff diversions. From 1992 to 2008, total
influent flow ranged from 227 to 255 million gallons per day (mgd). Rainfall was relatively
abundant during 1993, 1995, 1998, and 2005.
Influent flows received from tributary areas in Los Angeles County are assumed to be offset by
Orange County flows tributary to Los Angeles County.
3.2.3 Projected Flow
3.2.3.1 Unit Flow Coefficients
Wastewater flow projections are based on projected service area population and a unit flow
coefficient expressed in gallons per capita per day(gpcd). The coefficient characterizes an
average per capita usage in the service area. The ISPU completed in 2002 assumed unit flow
coefficients ranging from 104 gpcd in 2001 to 115 gpcd in 2020. However, in November 2004,
OCSD revised its 2020 flow projections for treatment capacity based on actual flows, using a unit
flow coefficient of 104 gpcd. For the purposes of this Master Plan, unit flow coefficients have been
further revised to correspond with observed influent flow trends. They are shown in Table 3-2.
Note that the gpcd for 2006-07 was 91.6, which was an unusually dry year, and the beginning of
an economic recession. The unit flow coefficients are also applicable to the MWRP tributary area
and anticipate a reduced flow, which would result from increased reclamation in the MWRP
tributary area following expansion of the MWRP and completion of the Harvard Avenue Trunk
diversion project.

3.2.3.2 Average Daily Flow Projection
Average daily influent flow projections between 2007 and 2030 are based on projected populations
and other factors, including base groundwater infiltration. Rainfall in previous years has been
below average, and it is expected that the flow from base groundwater infiltration will return to
normal sometime in the future. The unit coefficients are presented in Table 3-2.
For planning purposes, SAWPA flows are assumed to increase from 9.6 mgd in 2005 to 20 mgd in
2030. Flows through the Main Street flume, which include flow from the MWRP, are assumed to
be 11.4 mgd in 2005 with an anticipated reduction to 3.0 mgd by 2015.
Despite population increases, flows to OCSD from the MWRP tributary area are expected to
decrease due to expanded reclamation at MWRP. Over the same time period, urban runoff
diversions are assumed to increase from 1.4 mgd in 2005 to 10.0 mgd in 2030. From 2005 to 2030,
flows tributary to Plant Nos. 1 and 2 are projected to increase as much as 17.66 percent.
Assuming increased flows from OCSD Plant Nos. 1 and 2 tributary areas, urban runoff, and
SAWPA, and reduced flows from the MWRP tributary area, total flows are projected to increase
approximately 20.35 percent(see Table 3-3).

4. Asset Summaries and Total Cost of Ownership
4.1 Introduction
The key objective in developing Asset Management System Summaries is to assemble a
comprehensive list of assets and to enable OCSD to start to filter and focus on those assets that
are most critical.
In the 2006 Asset Management Plan, OCSD commenced the process of including life cycle asset
management sections relating to the key asset types and key system groups. Section 4.2
discusses the development of the Treatment Plant Asset Management Plans. The relation of the
various plans to the Executive Management Team (EMT), managers and staff is shown below in
Figure 4.1.

Asset Facility/Trunk Strategy--Plans
Of the documents noted in Figure 4-1 the Asset Management Plans Executive Summary and the
Asset Management Plan have been developed. An initial summary statement of the Treatment
Plant Asset Management Plans has been prepared and included in the Section 4.2.
Section 4.3 discusses best appropriate practices with regards to the full cost of infrastructure
service delivery. Section 4.3 is a discussion paper with respect to the future Asset Management
Plan (AMP); it is valuable information and should be read as part of this plan.
4.2 Asset Management System Summary Plans
This section of the Asset Management Plan is a second pass at outlining the status of key process
areas in the plants. It provides details of Reclamation Plant No. 1 and Treatment Plant No. 2 at an
area level, summarizing the assets' functions, key design features, capacity factors, current
performance assessment, key issues for further investigation, current program and a financial
summary of the plant area.
25
Orange County Sanitation District-Asset Management Plan FY 2011-12
At the end of each asset system summary is a full schematic showing the overall process flow for
each plant. This is to assist the management and operation of the assets at the agreed levels of
service (defined in this plan) while optimizing lifecycle costs.
4.2.1 Uses of Asset Strategy Plans
The Asset Strategy Plans have been developed as a tool to meet the various needs of
stakeholders. Potential uses for the following system level summaries include:
P Explaining the business process used to develop CIP projects and maintenance strategies;
P Providing context for explaining new CIP projects to the board;
r Educating supplement on how the collection and plants work;
P Reviewing drivers and condition of assets when reviewing CIP project business cases;
r Documenting condition and key issues for further investigation;
P Assisting with setting of division goals on a yearly basis;
o Summarizing operational strategies;
r Providing reference information for the current system and strategies and a structure for
communicating future strategies for assets.
4.2.2 Asset Management System Summaries
The following Asset summaries have been updated from the previous 2008 AMP. These are
based on the updated plant schematics for Plant 1 and 2.
P Preliminary Treatment;
o Primary Treatment;
P Secondary Treatment;
r Solid Handling;
r Utilities;
P Central Power Generation System;
r Ocean Outfall.

4.2.3 Structure of Asset Management System Summaries
Each of the Asset Management System Summaries has been built around a common structure.
This structure provides a framework for the continued use and development of the summaries.
The key elements of the structure for each key process area of the plant are:
r Asset Profile-Description of the assets, its primary functions, and recent relevant history;
r Demand Profile and Performance- Describes the key capacity design values for assets in
terms of minimum, maximum, peak or average flow requirements, and where available, the
current performance
r Failure Mode- Data is provided when it is known. For each of the primary failure modes, a
summary score on a 1 -5 scale is provided, on how the asset is performing. The meaning of
these ratings are defined in Appendices E;
r Key Issues for Further Investigation- Issues are listed based on O&M staff member
comments, and identified issues from the Demand Performance and Failure Mode information;
r Current Program- Describe the current studies, planning, design and construction and
management strategy for that area of the plant;
r Investment Program-Defines funding summaries for the plant over the recent past and
several future periods.
It is expected that the flow of information should be developed so that Key Issues for Further
Investigation is maintained and the Current Program and Investment program reflect the agreed
works. Figure 4-2 shows the general flow of information through the summary. Staff member
input is to be solicited for all the elements.

4.2.5 Future Asset Summary Development
The Asset Management System Summaries will continue to be maintained and developed over the
coming years by the asset management engineers and program manager.
Future development of the completed asset summaries will be achieved through building these
summaries electronically, and linking them to detailed asset management plans for each asset
summary with additional asset data.
4.3 Full Economic Cost of Infrastructure Service Delivery
4.3.1 Introduction
Owners of infrastructure need to understand the"true" economic cost of their infrastructure assets.
Understanding the bottom line or the point at which the assets become non-economic to own and
operate is important. This is one of the identified failure modes for an asset. This section of the
report outlines the latest approaches in this area.
It is intended that OCSD will transition to report cost of service in this manner in the future. It will
not displace the current cash or accounting processes but will provide management with another
source of information useful in optimized decision making.
There are different costs that occur in each phase of an asset's fife. Depending on the level of
service intended, it is possible to provide service at vastly different cost levels.
OCSD will turn its focus from the initial capital costs of creation and acquisition to the overall
Iifecycle cost. For some short-lived or dynamic assets, recurrent expenditures for the operations
and maintenance of assets represent a significant proportion of the total life cycle costs of these
assets.
It is important to be able to attribute the costs to each phase in an asset's life cycle so that the total
life cycle costs (or total cost of ownership) can be established to enable better decision-making by
management.
4.3.2 Cost Elements
The cost of infrastructure asset services is quite complex and it is vital to understand not only the
current costs but also the long-term life cycle costs and the current position of the asset in the
asset life cycle as shown in the following Figure 4-3.

CREATE MAINTAIN REFURBISH
The key elements in asset costing for OCSD may include the following:
Financial costs;
Asset depreciation;
Asset operations including collection systems;
Asset maintenance;
Asset administration; and
Disposal costs.
Capital investments occur at asset creation or acquisition and can continue throughout the life of
the asset in the forms of major repairs, improvements, rehabilitation, renewal, expansion; the blend
of Capital investment, and operations and maintenance activities will impact on the use of the asset
or its depreciation.
4.3.3 Quality of Outcome / Level of Service
The true costs of providing infrastructure services depend on the standard or level of service
required by OCSD and the community. While a high level of service is what every user may
desire, the full cost of providing that level of service must be shown so that a realistic level of
service is set and ties into the expectations of customers or stakeholders and appropriate annual
service fees. OCSD should strive to provide the required level of service at the lowest appropriate
costs.
4.3.4 Community Wealth
The intent of any good accounting standard should be to reflect the real condition of the entity in
terms of cash on hand, asset value or wealth and income, expenditure, and liability factors.
Modem infrastructure accounting standards have tried to develop techniques for measuring and
reporting this better than in the past.
67
Orange County Sanitation District-Asset Management Plan FY 2011-12
The Government Accounting Standard Board's Statement 34 attempted to do this; however,
several shortcomings in terms of historic cost and assets pre-1960 and real time condition have
severely weakened this objective. With long-lived infrastructure the key issue relates to each
asset's replacement cost and to the rate at which it is being consumed or used. By understanding
the true condition and performance of the assets, OCSD can also understand the individual wealth
of that community served by OCSD infrastructure.
This is similar to how most people think as home or car owners (except that they are market driven
values). The current property value is considered to be an "asset'. It appears in their overall
'wealth' assessment and as such they can see how their family business is going from a total
financial position.
It is no different for the custodians of the community's assets. Best appropriate practices show that
the elected members, directors and managers all need to work towards managing this
infrastructure in a "sustainable" manner for present and future generations. Understanding the full
economic cost is a key part of this picture. Respecting the proposition of"community wealth" is
critical to adopting an OCSD site speck"best appropriate practice" in this area.

4.3.5 Conclusions
The true cost of infrastructure services is heavily dependent on both the valuation and
consumption of assets (depreciation) process and true operating and maintenance costs. They
are critically related to the links between asset standards or levels of service and the most
appropriate maintenance, capital investment and operating regimes. OCSD needs to understand
this relationship and its accurate cost of service (full economic). This is an asset cost based model
and the issue of cost versus price/value needs to be considered.
To provide a clear picture of whether the ratepayers of today are meeting their share of the system
costs, it is necessary to look at the annuity of the future capital cash flow based on well-developed
and detailed Asset Management Plans.
This type of an Asset Management Plan has a high confidence level rating (CLR)through
maintenance plans and CIPs that consider the triple bottom line.
The benefits to OCSD of making a transition to a "full economic costs" model is that it will now
have a picture of life cycle cost where the increased costs in one area must be reflected in a
suitable reduction or trade off in another area.
68
Orange County Sanitation District-Asset Management Plan FY 2011-12
Capital investment reduces operating and maintenance costs or business risk exposure or there is
a beneficial improvement in the levels of service offered. This type of model can then be shared
with the OCSD member cities and agencies as an example of best appropriate practices.
5. OCSD Asset Management Model
5.1 Model Background
In 1998, OCSD commissioned a study with R.W. Beck to analyze future asset replacement needs
and to deliver a computer model that could be used to project alternative scenarios for funding
replacements. This study used two parallel efforts; the first was building a system inventory of both
existing and anticipated future assets with a method for estimating replacement costs.
The second effort used those estimated replacement costs to generate a future expenditure plan
and related user fees and rate to fund the expenditure plan. This work represented a significant
step forward for long-term asset expenditure planning for OCSD. The modeling work included
many best practice approaches including:
r An asset register based on financial project records;
r Indexed current replacement costs;
P Future costs escalated by construction cost indices;
P Asset useful lives for different asset types; and
r Estimated expenditures at set points in asset lives based on asset age.
As a financial planning tool this was a great improvement from previous processes. The approach
used to build the information is considered a "top down'view of the assets and necessarily makes
some broad assumptions about asset condition and performance in estimating the expected
expenditures. The model constructed was limited to a 20-year projection of asset expenditure
needs.
OCSD first Asset Management Plan (2005) approached the question of asset replacement needs
from the "bottom up" perspective by:
r Building a detailed asset register based on a complete asset hierarchy(an asset by asset
compilation);
P Populating the information in the model with more detailed data about each asset that was
used to make a more educated estimate of actual asset rehabilitation and replacement funding
needs.
The analysis was run for a 100-year projection, thereby more closely matching the actual needs of
many of OCSD's long-lived assets. The model attempted to improve on the R.W. Beck model by
considering the following issues:
o A comparison between the OCSD Computerized Maintenance Management System database
and the R.W. Beck asset register shows that some assets may not be accounted for(for
example, the outfall, although mentioned in the report, does not appear in the database);
o Better asset data is now available since the R.W. Beck model was developed;
P The asset breakdown in the R.W. Beck model is too high a level to derive more accurate
renewal figures.
69
Orange County Sanitation District-Asset Management Plan FY 2011-12
r This is due to the fact that the OCSD Financial Information System catalogues asset
information by CIP and not to actual assets. The Asset Management Plan constructed an
asset register to a lower hierarchical level for this application to be achieved.
P The replacement valuation has been completed at an asset project level and as such:
The component replacements have not made sufficient allowance for'component renewal factors'
necessary for life extension models; and
The replacement valuations made allowance for the cost indices from the original date of
construction or used current replacement tables, but did not make the necessary adjustments for
the fact that many assets were built in an undeveloped environment and will now have to be
renewed or replaced in a developed environment.
r The average asset lives used in the R.W. Beck model was based solely on asset age. This
does not account for the various factors that will contribute to the typical decay of like assets. It
is vital that the knowledge of key staff is used to supplement this information in terms of known
performance or condition;
P The rehabilitation/renewal assumption are reasonable for mechanical /electrical assets;
however, they need to be adjusted to reflect the basis for civil structures and pipelines;
P To better understand the renewal dates it is vital to understand the criticality of an asset; there
is a need to include Business Risk Exposure allowances into the model;
r The model makes no allowance for maintenance allocations for new assets and assumes that
the assets will actually reach their effective lives;
r Assets whose lives are consumed are renewed or replaced but only for one cycle. To run a full
cost analysis over a 50 year timeframe it is essential that these assets are renewed and
commence again; and
P It is now believed that it is best to express all future cost models in current cost terms and not
to make assumptions for inflation or cost indices. Future customers and ratepayers should be
allowed for but costs should be expressed in 2006 dollars. This is believed to give a better
response from ratepayer surveys as it allows them to assess the impact in terms that they
know, "How do I feel about it in my financial environment today?"
In the development of OCSD first Asset Management Plan in 2005, it was decided after some
review of the existing data and OCSD's internal knowledge of the asset condition that the only
comprehensive data currently available in electronic format was in the Computerized Maintenance
Management System, the Geographic Information System and the Facilities Atlas. Thus, this is
what was used for the model analysis in this report.
5.2 The Asset Management System Summary Plans
To meet the objectives outlined in the previous sections of this Asset Management Plan, a series
of Calculations was performed on the current and future OCSD assets. To facilitate this process, a
Future Expenditure Model was developed, which is designed to:
r Merge together a number of sources of data from across OCSD;
o Create and summarize management strategies for each asset type or individual asset;
o Estimate the treatment and associated costs by year for 100 years,
r Estimate an asset valuation for each asset; and
P Report on future expenditure and value of the asset portfolio.
70
Orange County Sanitation District-Asset Management Plan FY 2011-12
The Future Expenditure Model can be used in several ways to better understand and make
decisions about the assets. Some of the existing uses include:
r Calculate the future expenditure profile of the organization, including capital, operations and
maintenance costs;
r Identify those assets that are approaching the end of life and require further analysis and
possible inclusion in the CIP;
r Prioritize the review of assets based on their risk profiles; and
P Optimize the management strategy for an asset, including the intervention points based on risk,
cost or condition.
This model draws together data from a number of sources across OCSD. Some of data was
extracted from the existing OCSD information systems, while other data was estimated for the
purposes of this Asset Management Plan.
The Future Expenditure Model considers the full life cycle of the assets, starting with construction
through to disposal. The model can be used to model any future time period; however, the
modeling has been projected over the next 100 years so that replacement of the longest effective
lives are incorporated into the planning period.
5.2.1 Asset Management Plan 2005 Development
The major steps undertaken in the Future Expenditure Model development for Asset Management
Plan 2005 were as follows:
o Development of the Asset Management Plan 2005 Future Expenditure Model
Methodology- Developed all the formulas and logic required to perform the necessary
calculations;
P Review of Existing Data Sources-The major data sources from OCSD were reviewed and
data was chosen and used in the Future Expenditure Model;
P Asset Register Population and Validation -A complete asset register was developed for
OCSD and populated with the data discussed above;
r Asset Condition (CIP Projects)- Many of the existing assets are planned to be replaced in
the existing CIP. The replacement data from Engineering was gathered on all of the present
and future CIP projects and used to estimate future replacement dates;
r Asset Lives Estimation -An estimate of asset fife (from new condition)was developed for all
major asset types;
r Asset Valuation Development-An estimate of cost for each major asset type was
developed;
P Failure Mode Prediction - Failure modes based on age, cost effectiveness, and risk were
calculated for each major asset type;
P Residual Economic Asset Lives (Age and Condition)- Based on age and condition, the
remaining economic life by asset type was calculated;
o Asset Criticality—Based on probability and consequence of failure, high-risk assets were
identified;
71
Orange County Sanitation District-Asset Management Plan FY 2011-12
P Asset Strategies-Where possible, management strategies were identified to reduce risk and
premature asset failure;
P Cash Flow Model -Annual replacement costs were estimated from the above information.
5.2.2 Asset Management Plan 2006 Development
The major steps undertaken in its development for Asset Management Plan 2006 were as follows:
r Asset Condition (CIP Projects)—The CIP had changed significantly since 2005 with some
projects being completed and many projects having been revised and reviewed due to financial
constraints. Many of the existing assets are still planned to be replaced in the revised CIP but
the available level of detail and confidence in the data has improved as projects have moved
through design stages. Updated replacement data from Engineering was gathered on all of the
present and future CIP projects and used to estimate future replacement dates;
P Asset Register Population and Validation -A revised hierarchical asset register was
developed for OCSD and populated with the data discussed above;
r Asset Lives Estimation -An estimate of asset fife (from new condition data)was updated for
several major asset types based on Delphi workshops and current performance of assets;
i Residual Economic Asset Lives (Age and Condition)- Based on age and additional
condition data, the remaining economic life by asset type was re-calculated;
P Asset Criticality—Based on probability and consequence of failure, high-risk collection assets
were identified; and
P Asset Valuation Development-An estimate of valuation for the portfolio and each major
asset type was developed; and
r Cash Flow Model -Annual treatment costs at the asset level were estimated from the above
information, and validated against 2006/2007 maintenance programs for major items.
5.2.3 Asset Management Plan 2008 Development
The major steps undertaken in the future Expenditure Model for the Asset Management Plan 2008
were as follows:
r Asset Register Population and Validation -A revised hierarchical asset register was
developed for OCSD and populated with data from GHD's TeamPlan 2006, GIS, Fleet MMS,
and CMMS;
P CIP Projects—Following discussion with Engineering, the adopted approach for CIP projects
is to use the existing CIP data and costs, run the model, review the Team Plan outputs and
cross check the model results against the current CIP programs;

5.2.4 Asset Management Plan 2011 Development
As part of the constant asset management improvement process OCSD periodically updates its
future funding requirements using the TeamPlan software model. This refines and builds upon
previous model runs by incorporating new enhanced asset information. However, for this year it
was determined that the asset register was not up to date in reference to completed capital
improvement projects. In addition the CMMS improvement project was still in progress. When the
new CMMS system is properly implemented it will provide better data for the TeamPlan model win.
For these reasons, to improve the long term model projection the effort changed. It now focused
on eliminating assets from the list of renewals forecasted by the TeamPlan model based on
competed CIP's, and recreating the future investment needs figures to reflect the modified forecast
renewal expenditures. This resulted in 63 CIP projects being reviewed in reference to the
TeamPlan model. Out of this list of CIP's not all contained physical assets, some were completed
and others cancelled. The result of this had a refinement of the TeamPlan output from the
previous model run.
5.2.5 Asset Management Plan 2013 Development
The approach for producing this year's modeling results is extremely similarto the method
documented in 5.2.3. However, during the course of this project, some key events took place.
This year the existing management strategies were updated through a process slightly different.
New, was involving Brown and Caldwell (B&C) technical experts along with OCSD key staff and
GHD to review and update management strategies for OCSD assets. The purpose of this was to
get a third party expert perspective. In addition B&C ran the workshops, and produced a series of
maintenance plans for the assets that was previously undocumented by OCSD staff. New this
year was the inclusion of the OCSD land and pavement being included in the modeling. With the
implementation of MAXIMO the data sources for this model had to be re-established and validated.
The overall outcome of all of the above key events provides a higher confidence in the modeling
output.
5.3 Model Structure
The Future Expenditure Model has been structured around the existing OCSD data hierarchies
currently defined within OCSD's information systems. This has had several advantages, including:
P Reduces the need for large amounts of data manipulation;
P Allows for a critical analysis of the existing data hierarchies;
r Enables reports to be generated that are consistent across the organization; and
P Supports a direct link of the Future Expenditure Model into existing OCSD information systems
for updating of data.
73
Orange County Sanitation District-Asset Management Plan FY 2011-12
Due to the existing structure of the data within the OCSD information systems, four separate
hierarchy structures have been supported within the model. These are listed below:
r Gravity Pipes (System -> Area ->Trunk-> Street->Type ->Asset);
r Force Mains (System->Area -> Force Main -> Street->Type -> Asset);
r Plant Pipes (System ->Area-> Pipe Location -> Structure-> Material Type-> Asset); and
r Plant Assets (System ->Area -> Location -> Master Loop-> Loop-> Loop Tag Number->
Asset Type -> Asset).
Apart from the hierarchical structure of the OCSD assets, the Future Expenditure Model supports
two other levels of data input. The first of these is at the Asset Type level (e.g., gravity pipes,
pumps, gearboxes etc) of which there are currently 142 within the database, while the second of
these is at the asset itself. The types of data that can be entered into the model through these two
levels include:
r Asset Type Level
Asset Type assumptions, e.g. effective lives, unit rates, failure curves (this information cannot be
entered at an asset level); and
Asset Specific Attributes Assumptions, e.g. size, length, location (applied to assets where data is
not available on individual assets).
r Asset Level
Asset specific attributes, for example, size, length, location.
There are a number of reasons why the Future Expenditure Model was structured this way,
including:
r It enables asset management strategies to be changed for a number of assets at a single time;
r It allows assumptions to be applied to assets where data is not currently available; and
r It allows for updates from the existing OCSD information systems to be easily downloaded to
the Future Expenditure Model.
5.4 Data Sources and Collection
There were several sources of data used to populate the Future Expenditure Model; however, the
major ones were the OCSD new MAXIMO information systems, GIS data sets, and B&C experts
and OCSD staff("Delphi Group")workshops. Several workshops were conducted in order to fill
the data gaps with B&C and OCSD staff, chosen for their knowledge of the assets in question,
when asset information was not recorded in an existing OCSD computer system. This best
appropriate practice delivers the best"valued judgment" available to OCSD.
74
Orange County Sanitation District-Asset Management Plan FY 2011-12
5.5 Asset Register (Inventory)
OCSD is working on improving its CMMS and inventory information. This includes upgrading and
implementing MAXIMO CMMS software and improving the data quality and right sizing the
quantity. Once this is completed it is expected that the TeamPlan model output will be improved.
Currently the TeamPlan model contains more than 150,000 individual items collected from the data
sources listed above, which includes the fleet service assets. Not all of these items are considered
assets since they may be components of a larger asset. The relationships between the items are
set within the asset hierarchy. The majority of the items within the Future Expenditure Model are at
a level where maintenance activities are undertaken. Table 5-1 and 5-2 is an estimated
breakdown of the register against the main tiers of the asset register.

Figure 5-2-1 and 5-2-2 provides an overview of OCSD Assets. The distribution of the assets is
shown by its group and category. This provides a glimpse of the sheer number of all these assets
that are tracked in the CMMS and how they compare in overall value.
75
Orange County Sanitation District-Asset Management Plan FY 2011-12
The first pie chart shows the distribution by asset groups, whereas the second pie chart shows the
distribution by the replacement value for these asset groups.
The number of assets is dominated by the mechanical type assets, whereas the replacement value
of the assets is dominated by the civil type assets. The civil assets, including sewers, structures,
and roadways, generally have much longer lives than the Mechanical/Electrical/Instrumentation
assets and, therefore, even though the value of the civil assets is greater, the overall expenditure
on the assets will be more in proportion. Since the civil assets comprise such a large proportion of
the assets, they need to be maintained and monitored closely to prevent premature replacement.
However, civil assets such as force mains and sewers can be more difficult to inspect.

The model contains two "states" of the assets in reference to the replacement and depreciated
value.
The first state is the way the assets currently exist. The second state is the way the asset will exist
in the future after the existing CIP has been completed. This has enabled new assets and asset
renewals, both planned and under construction, to be included, allowing all the assets, both
present and future, to be modeled.
It is noted that several sets of assets have not yet been included in the inventory. These include
Information Technology. These asset sets should be included to improve the organization's
understanding of the asset base, and to ensure that appropriate management practice is being
applied to all assets.
5.6 Asset Condition Determination
The Asset Management staff continues to work on identifying OCSD's critical assets and their
current condition. As this information is generated and incorporated into OCSD's MAXIMO CMMS
it will provide the TeamPlan model improved condition information. This condition data can be
used to determine the remaining life of existing assets. At the present time, approximately only 5%
of assets have condition data generated by the maintenance staff. Thus, the condition of OCSD
assets is based on its individual age, estimated effective life, and estimated decay curve. The
exact installation dates for many of the assets are not known and have been estimated based on
historical information from CIP projects. The collection system has very good information on the
installation dates due to the recent Trunk Sewer Mapping Project which researched record
drawings.
n
Orange County Sanitation District-Asset Management Plan FY 2011-12
Each of the asset types is allocated a decay curve in the model, which determined the rate of
decay of the asset. Some assets were determined to decay at a constant rate throughout their life
such as cars, clarifier sweep arms, and bar screens, while other assets were determined to decay
quicker as they aged such as chemical mixers, fiber optic network and large civil structures.
Asset installation dates have been applied at the asset level, while the asset lives and decay
curves have been applied at the asset type level.
In the past a series of"Delphi group"workshops have been conducted with the collections and
engineering team to validate the asset conditions being predicted by the model. The model has
also been through an initial validation trial for major plant process assets. Such validation provided
a basic confidence that the model is identifying assets that are either due to be decommissioned or
about to have maintenance tasks undertaken on them.
5.7 Effective Lives
Estimated asset lives allows for making an educated guess of the condition of an assets and
consequently the timing of asset renewals. Two lives have been allocated to each asset type, the
maximum potential life of the asset, which is the time from installation to replacement if it is
maintained and rehabilitated and the effective life, which is the interval between rehabilitations.
Effective lives were determined based on the knowledge of the OCSD staff of the assets and
validated through external sources. Several factors were considered when determining the lives of
the assets, including:
r Historic failure history;
r Historic construction practices;
r Planned obsolescence and support phase out by manufacturers;
r Location and operational environmental;
r Level of quality of installed assets; and
r Maintenance Management strategy.
5.8 Asset Valuation
The replacement cost of the assets is used to determine the future expenditure requirements of the
organization. The valuation of the assets includes both construction and estimated OCSD
overhead costs. The valuation of the first Asset Management Plan assets was based on 2005
dollars which escalated by a total of 3%for 2006. From 2006 to 2008 it has escalated
approximately 5% per year. These are not the historical values as listed in the Financial
Information System. This current Asset Management Plan asset's is based on 2012 dollars.
In the past the majority of assets have been valued by assigning unit rates at the asset type level,
while a few individual assets were allocated individual replacement costs, where appropriate. The
asset replacement costs were developed by traditional "quantity surveying techniques" by OCSD
staff(cost estimators) and validated against recent projects. Several relationships have been
developed for many of the asset types, which relate asset size, length or location to the value of
78
Orange County Sanitation District-Asset Management Plan FY 2011-12
the asset. For example, the value of the collection system pipes varied by location within the
system, depth, size and length.
5.9 Operations and Maintenance Costs
In 2005 the Asset Management Plan operations and maintenance costs were estimated by
inflating historical OCSD costs. Since 2006 an improved methodology was used based on actual
budget figures for the initial year. The prediction of operations costs has been calculated as a
percentage of the estimated replacement value of the assets in a given year. The prediction of
maintenance costs has been calculated using an inverse function of the estimated written down
replacement value or depreciated over replacement value in a given year.
In future years this methodology will be modified to better predict these costs and to align with
OCSD budget components. This will result in a better correlation between the model results and
the budget. An example of an opportunity for improvement includes changing the categorization of
major mechanical equipment in the model to include expenditure in the maintenance budget rather
than the CIP budget.
5.10 Predicted Failure Modes
The failure mode of the asset determines the timing of the renewal of the asset and potentially how
the asset may eventually fail. For this Asset Management Plan, the following failure modes have
been considered for each asset.
r Asset Renewal(Replacement and Rehabilitation)—The timing of the replacement or
rehabilitation of the asset is determined by the condition of the asset, which is calculated based
on its age, expected lives and decay curve. The model uses a methodology, which optimizes
the liming of the asset replacement to minimize the life cycle cost;
r Levels of Service— If the service that the asset is providing is no longer adequate, then it is
considered to fail to meet the required level of service.
r Growth/Demand—An asset can fail If the demand for the asset exceeds the existing
capacity.
5.11 Asset Criticality— Business Risk Exposure
The criticality of an asset can be determined by quantifying it with a Business Risk Exposure score.
This can be used to determine the strategy for the management of an asset, since more critical
assets should be managed / maintained to a greater degree than less critical assets. A Business
Risk Exposure score can be quantified by multiplying the probability rating of a failure occurring by
the consequences rating of that failure.
Collection System
A sophisticated Business Risk Exposure model has been developed for the collection system, to
enable the prioritization of asset condition assessments and cleaning.
The outputs of this model will also be used to identify potential future CIP projects and will be used
in conjunction with capacity modeling currently being undertaken.
Two separate Business Risk Exposure models were developed for this Asset Management Plan,
the first for the structural failure sub mode (asset decay or collapse)for Asset Renewal failure and
7s
Orange County Sanitation District-Asset Management Plan FY 2011-12
the second for the operational failure sub mode (partial or complete blockage) of Level of Service
failure.
A number of factors were used to determine these criticalities, including the predicted condition of
the assets, capacity, location, depth, HzS, soil, land use and the pipe diameter and slope.
Plants
Another asset criticality model is being developed for the plant facility and process area assets and
is to be implemented in the future. This considers a limited number of factors in the consequence
and probability equation to enable a quick identification of assets that have a high Business Risk
Exposure, and that require additional condition assessment and management.
6. State of the Assets Summary
6.1 Asset Valuation
The current replacement value has grown to be $6.20B, which compares to the 1998 RW Beck
study prediction of$2.03B and the 2004 GHD estimate of$5.38B. This is estimated to increase to
approximately$7.86B after the completion of the existing CIP in FY 2019-20.

Orange County Sanitation District-Asset Management Plan FY 2011-12
The current valuation has been based on:
r The asset register contains nearly all assets including:
o The entire gravity collection sewer system, split into individual sewer lengths and
manholes; force mains;
o All the collection sewer pump stations and other critical assets including the siphons
and associated assets;
o All structures and pipeline assets in the plants; and many plant infrastructure assets not
included originally.
r The fact that the asset register now has a hierarchical structure, which allows the drilling down
into each facility and asset to a level of component that was not previously available. There
are now over 150,000 line items in the register as compared with 5,000 assets in the original
RW Beck model;
r The asset replacement values are now based on the assets being rehabilitated or replaced in
developed areas rather than undeveloped which the majority were originally constructed. Most
future asset rehabilitation or replacement will be completed in the confines of the existing
plants, working inside office and shop buildings, assets that need to be kept operational, or in
right of ways with high levels of traffic resulting in customer and community inconvenience.
In many cases, the existing asset would require demolition before the asset can be replaced
which might require temporary work to be put in place. All this results in a far higher
replacement cost than a simple escalated initial construction cost projection would indicate;
r A greater level of asset"breakdown" and classification has been achieved, which has
increased the accuracy of the asset valuation; and
r The replacement valuations of these components have been made by OCSD engineering
estimating and costing personnel using a modern equivalent asset approach.
The actual replacement value of the assets is an important tool in understanding sound asset
management; however, it is the money required to be spent on these assets in terms of capital,
operations and maintenance that represents the most critical issue from OCSD's perspective. This
is the prime purpose of this modeling and continues the work done by the Sanitation District in
previous Asset Management Plans.

Figure shows that the bulk of the collection assets are between 21% -70% consumed, which is

last 50 years, and as expected the asset base being in generally good physical condition.

In future Asset Management Plans, these types of chart will be used to demonstrate the changing
state of the assets over time; for example, this profile will be significantly different after the
completion of the current CIP approximately in the year FY 2019-2020. This type of chart will also
be used for scenario modeling to obverse the impact of differing levels of investment in
maintenance compared to CIP.
6.3 Improvement Program
The opportunity for improving asset management decisions rests in the quality and
comprehensiveness of information presented to, and understood by, the decision maker. To go
beyond an asset management model, requires a more labor intense effort, especially as it relates
to a Waste Water Treatment Plant and its large number and various types of assets. To
accomplish this OCSD has tasked highly knowledgeable engineers to be responsible for defined
systems. These asset management systems are identified in Chapter 4.
One of the purposes of this effort is to identify how best to cost effectively sustain the facilities with
the minimum investment of human and financial resources. In general some of the engineering
strategies for focusing on identifying sustainability and cost savings are: assets with the highest
85
Orange County sanitation District-Asset Management Plan FY 2011-12
probability of failure; assets with a high consequence of failure (for example, the costs of the
failure, environmental impacts, and regulatory violation if the event actually occurs); and assets
that are at a stage where rehabilitation in the near future would cost effectively extend their lives.
This approach provides adequate time for properly planning necessary rehabilitation projects.
7. Long, Medium, and Short Term Asset Management
This section of the Asset Management Plan describes the results of the modeling work described
in the previous section.
The results shown here are for a 100-year period. The confidence of the timing predictions in the
first 20 years is relatively high and reduces proportionately after this initial period; however, the
confidence of the actual renewal needs will remain higher. The 100-year forecast encompasses
the longest life of any of the assets, allowing the full life cycle of the assets to be modeled, thus
decreasing the chance of a future event that has not been considered. Mechanical and
instrument/electrical/computer type assets may be replaced many times in a 100-year period. Only
the first 20 years will be used for cash flow or rate modeling.
7.1 Long Term Asset Replacement and Refurbishment Model
7.1.1 Collection System
The collection system comprises slightly more than half the value of the OCSD assets; therefore,
its management has a large impact on the overall life cycle cost of the OCSD assets. The
collection system is not very visible, since the majority of it is buried, resulting in community and
external stakeholders often not understanding its importance or the costs associated with its
construction, operation, and maintenance.
Figure 7-1 provides a snapshot of the collection system by showing the average age of the gravity
pipes. There are two alternative methods of this calculation shown; the first weights the age of the
pipes based on the replacement value while the second method weights the age of the gravity
pipes based on the individual lengths of the pipe segments.
The figure clearly shows that the largest investment in the assets was during the 1960's and
1970's and that the average age of the system is steadily increasing with time. Based on the
predicted maximum potential lives of the assets, the maximum life that gravity pipes such as VCP
are expected to reach is 125 years old.
Therefore, at any point in time in the future, the average age of the collection system will be
between 1 and 125 years, depending on the renewals work that has recently been undertaken. It
is important to note that just because an asset is decaying or getting older, deterioration is not
necessarily the result of poor management or insufficient investment. In reality, all assets decay
and when required they get replaced or rehabilitated after they are no longer delivering the level of
service that is required of them.
As the average age of the collection system increases, then it logically follows that in the near
future there will be considerable investment required to renew this system after the existing pipes
are no longer meeting the required level of service or when the business risk of the pipes failing is
too high to manage efficiently. Figure 7-2 is the future predicted expenditure for the existing
collection system, showing the considerable investment required in the near future.

Orange County Sanitation District-Asset Management Plan FY 2011-12
The initial investment phase is dominated by rehabilitation as the average age of the system is
reaching halfway through the average maximum potential lives; this is followed by a long period of
increasing replacement. On average, OCSD may need to invest potentially$43M (2012 dollars)
every year to sustain the existing collection system, though as can be seen from Figure 6-2 a
higher value may need to be invested in rehabilitation for several years prior to 2025.
7.1.2 Plant Systems
Figure 7-3 provides a snapshot of the plant systems by showing the average age of the assets.
The figure shows a large investment in the assets was during the 1970's and 1980's, and that the
average age of the system is steadily increasing with time. Based on the predicted maximum
potential lives of the assets, the average maximum life of the assets is 77 years. Therefore, at any
point in time in the future, the average age of the treatment and disposal systems will be between
1 and 77 years, depending on the renewals work that has recently been undertaken. This average
life is greatly influenced by the civil structures within the plants as they make up the large
proportion of the replacement value and they have much longer lives than the electrical,
mechanical and instrumentation type assets. It is expected that the weighted average age of the
plant will be reduced as a result of the current CIP.

7.2 Long Term Cash Flow Model
This section details the long-term cash flows required providing sustainable assets to deliver the
required level of service for the customers. This section does not include the cash flows required
to finance this expenditure, such as interest costs, which are included in a later section.
The cash flows included here are for capital, operations and maintenance investments only.
7.2.1 Capital Cash Flows
Figure 7-5 shows the cash flows required to replace and rehabilitate the existing assets, which is
the combination of the charts in the previous sections. This chart also includes the existing OCSD
CIP, which is comprised of both capital to replace and rehabilitate existing assets and capital
money to increase the existing treatment levels of the service.

The major reason for the high expenditures in the early years is the expansion of the existing
treatment from partial to full secondary treatment. The huge cost of the expansion to full
secondary treatment is a one-time event. Such a major change in level of service is unlikely to
occur again based on EPA NPDES requirements. The cost to replace and rehabilitate these new
assets (CIP) later in their lives has been included in the above cash flows.
Figure 7-6 models other possible future increases in level of service. It is predicted that in the next
100 years that there will be another two major changes in level of service (for example, conversion
to tertiary treatment or upgrade of the existing treatment processes). It also includes an allocation
for the replacement and rehabilitation of these future predicted assets.
Growth in the demand for the services provided by OCSD is also likely as the number of people
living within the service area increases. As the existing CIP already allows for future growth for the
next 15 years, no allocation for growth has been made for this period. It is assumed that the
demand for the services will increase for the next 50 years; however, the current growth rates will
not be sustained due to build-out of the drainage basins and decreasing water consumptions per
capita. Such reductions are likely from water use education programs and water saving
appliances. No assumptions were made in the modeling for increased risks due to increased
levels of water conservation and on-site reuse that would present added risks to the
regional sewers and plant process.

7.2.2 Operations and Maintenance Cash Flows
The predicted long-term operations and maintenance cash flows are illustrated in Figure 7-7 this
chart also graphs the predicted total replacement value of the assets and the depreciated (book
value) value of the assets. These operations and maintenance budgets were estimated from the
existing budgets within OCSD; however, they are factored up or down to reflect the future state of
the assets. The operations budget has been linked directly to the replacement value of the assets
and increases as more assets are constructed. The operations budget will need to increase
significantly after the existing CIP is completed and for each future increase in levels of service.
This reflects increased requirements for more chemicals, electricity and operator, and also certain
maintenance labor needs, and specialized service providers.

Unlike previous models where the operating expenses were broken into three categories:
operations, maintenance, and administration, this year the operations budget came directly from
an OCSD budget document. This report broke down the operating expense, revenue, capital
investments, and other budgetary and financial items. The operating expenses were taken from
the report and used to produce the estimated operating expenses for the next 100 years. It's
important to note that the operating expenses include in this model do not include Equity Sales,
Intra-district Transfer, or Debt Services.
7.2.3 Total Cash Flows
Figure 7-8 is the result when the cash flow estimates from the earlier sections are combined.
The flat black line is the average of all the future cash flows, which represents the average
expenditure ($375M) required by OCSD for each of the next 100 years. The exact yearly
expenditure will vary depending on the actual work required. At present, the expenditure is lower
due to the gap between expansion and rehabilitation CIP workload; however, additional income in
the future will also be required to pay back the capital that was borrowed to complete the full
secondary treatment level of service upgrades.

7.3 Long Term Rate Implications
In the Asset Management Plan 2008, to determine the rate levels needed to support the
future expenditures modeled, a summary of all cash flows projected through to 2019-20
(including revenue sources as well as the capital and operations and maintenance
expenditures described above)was prepared in a rates model. This summary showed
that rate increases on the order of 10 percent per year would need to continue through to
2012-13, which is also the last year with new Certificates of Participation (debt) issuance
projected. Annual rate increases will need to continue beyond that point but projected at
a somewhat slower pace. It is expected that increasing levels of regulation including
climate change drivers will impact the current plan. At this time there is inadequate data
for what these changes may be for modeling purposes.
In early 2008, the summary of the rates model was updated in preparation for the FY 08-
09 and 09-10 two-year budget. Today, this rate program indicates that the revised rate
profile needed to be approximate 10% per year through to 2012-13. By 2019-20 annual
single-family residential user fees are projected at a nominal value of$402 per year. It
should be noted that in current dollars this rate is in line with the current state average.
The rate model was completed prior to the update of the Future Expenditure Model. The
next revision of the rate model should consider an updated version of this Future
Expenditure Model.
7.4 Long Term Sustainability
Sustainable Asset Management is critical to the long-term management of this complex
infrastructure.
Long-term sustainability is achieved by meeting the current costs applicable to current
users and predicting their future costs. Current costs include:
• Capital (Interest and redemption);
• Depreciation (the deterioration and consumption of assets);
• Operations;
• Maintenance; and
• Administration.
OCSD is developing the processes to identify these costs more accurately. The actual
rate of deterioration is the greatest unknown. This is not unique to OCSD or other public
utilities managing assets of these types. These future costing issues have also been
discussed in Section 4.3 of this Asset Management Plan. The key area for improvement
will be the accuracy of the future predictions.
94
Orange County sanitation District-Asset Management Plan FY 2011-12
7.5 Medium Term Sustainability— 1 to 15 Year Time Frame
OCSD continues to work towards creating a more definite capital plan. The emphasis
being to develop more detailed and comprehensive scopes of work, that maximize
delivery efficiency, and create a clear decision making framework for Operations and
Maintenance management. Due to the number of OCSD assets and varying ages every
major process train in the treatment plants should have a refurbishment project in
execution or being planned as they tend to have more wear and tear related issues and
more complex control and electrical system requirements. Pump station and collection
system assets generally require less frequent refurbishment cycles. Project scheduling
and prioritization will be based on the condition and criticality of the various assets that
make up the process train.
The long term modeling does a good job of projecting the overall cash flow requirements
in future years. The model creates a Future Renewal on Existing CIP cash flow category
that generally projects future needs. While this is useful and generally accurate, we
continue to strive do a betterjob. Specifically, in the one to fifteen year time frame by
creating much more specific project plans, which should be consistent with the modeling
predictions regarding the overall cash flow requirements.
The asset engineers, working with Engineering Planning, Operations and Maintenance
personnel are creating and constantly updating design level scopes of work for all
treatment plant process trains and collection system assets that are projected to need
refurbishment in the next fifteen to twenty years. These scopes of work are to be
sufficiently detailed to provide the Project Management Office with all of the work
elements necessary to create a construction package to refurbish the process train or
collection system to meet its level of service for fifteen years without another major
project. It is understood that individual assets may fail prematurely and that short term
actions like coatings and repairs will be necessary. These short tens actions will be
discussed later in the document.
The scopes of work created and maintained by the asset engineer will be posted on the
Sanitation District's intranet and will be available to all staff for input. The scopes of work
are a gathering place for all required actions, research opportunities, and process study
ideas. On an annual basis the Sanitation District will send the scopes of work to its
estimators to create a +35%/-10% estimate for inclusion CIP. Projects will be sequenced
based upon the condition and criticality of the assets in the scope, projected capacity
shortfalls, changes to the required level of service, available cash flow, and available
resources to execute projects. Engineering planning maintains the current project
execution schedule looking forward.
The project sequencing is very important for several reasons. As projects are nearing
initiation in the PMO, all research on possible technology improvements must be
completed and must provide a recommendation in the scope of work.
All asset condition studies that are identified should be completed to the greatest extent
possible and the results included in the project scope. All process optimization or process
95
Orange County Sanitation District-Asset Management Plan FY 2011-12
control upgrade studies should be complete with recommendations incorporated in the
scopes of work. The project sequencing of future projects is a bit fluid in the out years
based on new incoming information, but the work to be initiated in the near term should
be more complete and the estimates more accurate. Understanding the future project
sequencing will help to focus the efforts of planning, asset management, and research
engineers, as well as, help to focus input from Operations and Maintenance (O&M) staff
prior to the initiation of project activities. This will led to more accurate cash flow
projection, lower project execution cost, greater project delivery velocity, and reduced
change order percentages.
Operations and Maintenance will also benefit from this improved planning visibility. One
of the principle benefits will be the increased availability of process systems. It is
anticipated that there will be fewer projects requiring coordination and assets will have
longer cycles of availability to operations. Also, ideas and requests for improvements will
not be lost between submission and project start. Ideas are collected in the scope of
work, generally as a study or investigation item and are retained until resolved.
Lastly, having a very good understanding of when the next major refurbishment projects
is scheduled will allow maintenance personnel to make better replace versus refurbish
decisions on individual assets.
7.6 Short Term — One Year Time Frame
The asset engineers are actively working with Operations and Maintenance supervision to
gather and review performance and condition information on the assets they are
accountable for managing. The asset engineers continue to build and revise the scopes
of work that will become capital projects. In the process of reviewing their scopes of work,
asset engineers look for opportunities to manage risk, reduce Iifecycle costs, and
opportunities to defer larger projects when balancing these criteria.
Balancing the probability and consequences of asset failure (Risk management) is a
primary concern for the Sanitation District. Asset engineers are tasked with
understanding the function of all their assigned assets and the process systems they
form, as well as the condition of assets. Qualitatively understanding the consequences of
failure (system understanding) and the likelihood of failure (condition assessment) helps
to compare risks with other assets and make decisions when to rehab assets. Asset
Engineers use engineering judgment to provide Operations and Maintenance with
recommendations to manage risk more effectively. When possible the asset engineer will
identify operational changes to mitigate risk. This may take the form of different operating
set points or strategies that extend life or reduce stress on equipment. If operating
changes aren't adequate, the asset engineer will work with maintenance to adjust
maintenance activities to mitigate a risk. If that is insufficient and the next future
rehabilitation project is too far off, the asset engineer will work with maintenance to
budget the replacement or refurbishment of the asset or assets.
96
Orange County Sanitation District-Asset Management Plan FY 2011-12
When replacement or refurbishment of individual assets or small systems is required,
maintenance will take the lead in getting the work done. If the required work is beyond
the capabilities or capacity of maintenance, maintenance can turn the work over to
Facilities Engineering. They have the ability to specify and procure equipment for
maintenance to install or to outsource the replacement or refurbishment in its entirety.
In the area of lifecycle cost reduction, the asset engineers are tasked with finding ways to
cost effectively minimize the consumption of long term assets. One of the greatest
opportunities is in the area of corrosion control. This is especially true for very long life
civil assets like concrete structures and pipes. These systems have much greater life
spans than the electrical and mechanical systems around them. However, allowing these
long life civil assets to degrade to the point of requiring replacement is generally a very
costly outcome. Maintenance of these systems and structures to repair and protect
concrete and embedded steel can greatly reduce future capital project costs. The asset
engineers will create specific budget items for maintenance to address these repairs.
As a part of the annual capital budgeting process, asset engineers will review the scope
of work for upcoming projects in their area to look for opportunities to defer large capital
projects through alternate operating strategies, different maintenance techniques, or
targeted equipment replacement.
As the risk management activities and lifecycle cost reduction activities described above
are occurring it is possible that the priority of a planned project might be changed. The
annual capital budgeting process should reassess the sequencing of projects annually to
insure that only necessary projects are moving to execution.
8. Conclusions
The information contained within this AMP provides a basic understanding of OCSUS
asset makeup, its current asset replacement value, and its general asset condition. The
TeamPlan software model run was updated in this AMP by including the capital projects
completed to dale. Thus, there was a small change in the annual annuity expenditure. It
actually went down from the 2008 figure of$411 million to $406 million, which was in
2009 dollars. This was expected to be lower, since the completion of capital projects
were not included in the 2008 model run. The OCSD Finance division continues to rely
on this asset management software model results information. They use it for their
expenditure predictions to derive the average likely rate increases that could be required
to meet future expenditure scenarios.
OCSD has demonstrated an increased commitment to asset management by increasing
the number of staff dedicated to applying asset management principles. Because of this
OCSD believes the future asset management opportunities are greater now for the
medium and short term. It is expected with this change that over the years the asset
management effort will become more balanced and comprehensive in regard to a long,
medium, and short term action planning.

Orange County Sanitation District
Preventive Maintenance Program
Background:
This PMP is prepared and implemented as required by the WDR Section 13.iv.(b).
The PMP covers the assets managed in OCSD's sanitary sewer system and is one
component of the overall. The PMP is based on an approach that combines preventive,
predictive and corrective maintenance strategies and established best management
practices.
Overview:
OCSD manages 399 miles of gravity sewers comprising of manhole structures and their
connecting pipeline segments. As of November 2011, OCSD operates and maintains 15
pumping facilities and 32 miles of force mains. The Engineering Department is
continuously updating maps and asset register, and the exact mileage numbers may
change as data is refined.
OCSD does not own or maintain any portion of the sewer laterals that drain each privately
owned parcel or property up to the point of connection to the local sewer; thus, they are not
a part of this plan nor are they catalogued.
OCSD staff and/or contractors are used to perform the planned maintenance tasks at
scheduled frequencies as part of the asset level of care program. Frequencies are
established based on experience and attribute information to minimize risk of blockages or
equipment failures that could possibly lead to a SSO. Data from the work is recorded and
tracked through CMMS.
Hardcopy data files and paper records not recorded in our CMMS are available for review
and audit. SOPS and SMPs ensure consistency. These are available for some
maintenance tasks and are continuing to be developed for others. Mobile assets such as
service trucks, generators, and other equipment are not covered by this PMP but are
covered by plans developed by the Fleet Services unit of our Operations and Maintenance
Division.
Asset Inventory and Attribute Data:
Capital assets, minor components and their parts are catalogued in our paper records or
CMMS. Source or attribute data for each of these items is obtained from record drawings,
sewer maps, plans and specifications and/or supplier data. Levels of care for each item
are described in the tasks and frequencies information as catalogued in the CMMS or in
the interim, on lists or spreadsheets until the full CMMS implementation is completed.
1 of 4
Asset Level of Care Information
Preventive Maintenance Tasks:
OCSD developed and continues improving asset-specific maintenance tasks for the care of
each asset throughout its life cycle. Major PM task groupings are:
• Sewer inspection
• Condition assessment
• Sewer cleaning
• Pump station maintenance
• Chemical dosing for odor and corrosion control and wetwell grease mitigation
PM Frequencies:
As described above, the frequencies for preventive maintenance tasks are assigned to
each asset or groups of assets.
Gravity Sewers Program:
Experience has shown that smaller diameter gravity sewers (from 6-inches to 12-inches)
are more prone to blockages than larger diameter interceptor and trunk sewers. OCSD
established a 12 to 18-month schedule for production cleaning of smaller diameter sewers.
Higher-risk areas are on a 12-month cleaning schedule, while lower risk areas are on an
18-month schedule. Almost all of these small diameter sewers are located in the local
areas we manage: city of Tustin, Unincorporated Areas of Orange County within OCSD
Area 7.
OCSD uses combination cleaning trucks capable of hydraulically washing the pipe wall
followed by vacuum removal of the sewer debris at the next downstream manhole. Higher
frequency PM areas are on the Trouble Spot list. These line segments have a history of
blockages or SSOs mostly due to grease and roots. Trouble Spot areas are cleaned
weekly, monthly, quarterly, or in six or nine month periods as necessary, to prevent
blockages. Inverted siphons of all diameters are typically treated as trouble spots and
receive higher frequency care due to grease build up and/or debris settling.
Our medium and large diameter sewers are less prone to blockages thus receive a lower
level of inspection and cleaning. Our CCTV and manhole inspection programs are on
seven-year and five-year schedules, respectively. Each is also inspected before and after
any repairs done. Our cleaning schedule is as follows: Lines 42-inches diameter or less
are cleaned at least once every five years. Lines larger than 42-inches are cleaned as
required based on inspection or need (e.g. CIP projection, inspection).
Pressure Sewers and Pumping Facilities Program:
Isolation valves in the pressure sewers are exercised every three months to make sure
they are in good working order. Air/vacuum release valves are checked every six months.
The mechanical, electrical, and instrumentation equipment, and structural, landscape and
hardscape systems at the pumping facilities need various levels of care at regularly
scheduled frequencies. These schedules are shown in CMMS. Once work is completed, a
record is input and documented in CMMS.

Predictive Maintenance
Pd Tasks: (a subset of PM) are inspection and condition- assessment type tasks. These
are performed to determine if the planned preventive maintenance task should be done as
scheduled or rescheduled to a forward date if preventive maintenance, rehab or
replacement is not needed. PM tasks are therefore performed based on asset condition
and need rather than a strict time interval when maintenance may not be required. Pd
tasks include but are not limited to the following:
• CCTV video inspection of piping (NASSCO standards)
• Visual inspection of the manhole structures and their flow channels
• Trending of flow monitoring data
• Pump visual and dimensional inspection (impeller gap clearance for wear)
• Exercising of pump station equipment to verify correct function
• Thermal imaging of electrical systems
• Pump station pressure readings
• Vibration measurement of rotating equipment
• Ground surface inspection of rights of way and easements over the gravity sewers.
• Odor and corrosion assessment and monitoring programs.
The Pd program will continue to develop as technology expands.
Corrective Maintenance Tasks:
CM tasks are performed in response to a failure of an asset, component or part, or a
critical utility outage. Low-risk items, such as light bulbs, pressure gauges, sensors and
small non-critical valves are planned for run-to-failure, and as such are not part of the PM
Program. These items are replaced when they fail. When managed assets critical to the
process fail, they are scheduled for CM on an urgent or routine basis on a priority
schedule. Some of these repairs may be capitalized as a follow-up activity depending on
asset cost and life expectancy. These types of CM repairs include but are not limited to:
• Emergency cleaning to eliminate a pipe blockage
• Spot repair or replacement of a failed pipe
• Replacing a rattling or failed manhole cover
• Repairing or replacing a pump that has become clogged or damaged by debris
• Respond to, investigate and mitigate customer complaints and sewer overflows
• Repair of earthquake damage and
• Vandalism
Staff documents CM tasks on paper at the time of the event and then inputs them into our
CMMS database.
CCTV or other failure analysis may also be done by staff as a CM task after a problem
occurs to diagnose the cause of the problem and recommend changes if indicated.
Findings may lead to a spot repair of the pipe, root cutting, root foaming with an herbicide,
re-cleaning for grease or debris removal on a periodic preventive basis, or scheduling a
manhole-to-manhole pipe replacement or rehab in an urgent or lower priority planned
manner. Major replacement or rehab may be capitalized outside of the annual operating
budget.
3 of
Monitoring, Measurement and Program Modifications:
Findings related to scheduled or non-scheduled tasks and work order tracking will be
continually evaluated by staff to improve reliability and system performance. In assessing
the success of the PMP, changes in frequency or task activities, spare parts or
recommended stock levels will be reviewed by the Supervisor. Database changes and/or
new instructions to contractors will follow.
Items recommended for rehab or replacement through our CIP will be sent by the
Supervisor to the Staff Engineer for funding and planning by the Division or forwarded to
our Engineering Department for action in the agency wide CIP.
This program is subject to revision at any time with the goal of doing a better job more
efficiently. The process starts with suggestions from staff on possible ways to improve
tracking and managing of work.

ORANGE COUNTY SANITATION DISTRICT
Technical Memorandum
CJ p
TO: Christina Thomas
DATE: March 26, 2014
SUBJECT: Orange County Sanitation District's Collection System Capital
Improvement Program for Short and Long-Term Renewal and
Replacement Model (Statewide General WDR Section D. Provisions,
13. SSMP, iv. O&M Program, (c) R&R)
Purpose:
• Identify documents surveyed
• Review process used to select Capital Improvement Program (CIP) projects
• Review funding process (Finance Department)
• Review data sources for supporting CIP funding and project selection
Documents Surveyed
1) 2006 Strategic Plan Update
In early 2005, OCSD hired Montgomery Watson Harza (MWH)Americas to develop
a new computerized hydraulic model for the Collection System. The model was
based upon InfoWorks CS computer software by Innovyze. In early 2006, MWH
Americas completed the Collection System Strategic Plan Update which included the
hydraulic model and training for OCSD staff. The model was tied into OCSD's
Geographical Information System (GIS) mapping system for the Collection System.
The model is used to evaluate the current and future average daily flow, and peak
dry and wet weather flow in the Collection System. It fully satisfies all State of
California requirements mentioned in the 2006 Statewide General Waste Discharge
Requirements (WDR)for the Sewer System Management Plan (SSMP).
2) 2009 Facilities Master Plan
In December 2009, OCSD published Volume 3 (Final Report) of the Collection
System portion of the 2009 OCSD Facilities Master Plan. Volume 3 was an update
to the 2006 Collection System Strategic Plan Update developed by MWH. The
update utilized a version of OCSD's computerized hydraulic model which
incorporated revisions to the GIS information. The GIS information is constantly
being updated by OCSD personnel to better reflect current characteristics of the
pipeline network. Out of 20 potential CIP projects identified in the 2006 Strategic
Plan Update, eight of the projects were removed as not being required due to
modeled capacity verification criteria; one project was significantly modified; and one
project was delayed due to a street construction moratorium imposed by an Orange
County city.
3) Asset Management Plan FY 2013-14 and 2014-15
Coinciding with the two-year budget for Fiscal Year 2012-14, OCSD completed an
update for the Asset Management Plan (AMP) using a consultant from Gutterridge,
Haskins, and Daveys, Pry Ltd. (GHD) to run the TeamPlan software model. The
software modeling effort predicts the remaining asset life for the collection system
and plant facilities. The model management strategies were updated for this
software model run. The update of the management strategies included a
comprehensive review of the expected useful life of the collection system and plant
facilities assets. The revised model assumptions are documented in the SP-151
project report. This information was used to update the Asset Management Plan for
Fiscal Year 2013-15.
In addition, the results of the computerized hydraulic model are also used to
determine hydraulic deficiencies in the Collection System and improve the
confidence level rating in justification and validation of necessary CIP projects.
4) OCSD Budget
OCSD's Budget is adopted by the Board of Directors every two years. Prior to the
start of the second year it is updated by the staff. This comprehensive document
includes descriptions of all relevant policies, procedures, and processes. It includes
a financial summary, an operations overview, a description of all operating divisions,
an overview of the OCSD's self-insurance program, CIP details, and a debt service
summary.
5) OCSD Reserves Policy and Rate Setting Policy
The Board of Directors sets fiscal policy for OCSD which includes a policy for
reserves. District Summary (Section 4)of the OCSD Budget lists eight revenue
categories and their anticipated funding level by fiscal year. The amount of reserves
is itemized by revenue category and is projected forward for a duration of ten years.
6) CIP Budget Process and Evaluation Documents
Each year the Engineering Department evaluates and certifies all of the existing CIP
projects and the planned CIP projects for the next 10 year period. The Budget
"Capital Improvements" (Section 8) lists a summary of the Plant Treatment System
as well as the Collection System Improvement Projects. These projects are
validated based upon various criteria of capacity, regulatory, and condition
assessment needs.
2
7) Operations and Maintenance Department (O&M) — Collection Facilities O&M
Short and Long-term Renewal & Replacement Maintenance Project
Program
Every year O&M updates and prepares an operating budget to fund their activities
and expenses during the year. Many of these Repair and Replacement (R&R)
activities are performed under contract by specialty contractors. For example, O&M
has a closed-circuit television (CCTV) pipeline inspection program and a manhole
inspection program. The Engineering Planning division provides support for
condition assessments when required. O&M initiates necessary repairs when there
are structural or other facility deficiencies requiring R&R, that are under$100,000.
When necessary, O&M works with the Engineering Planning division to coordinate
major repairs on an asset in the collection system using CIP funds.
8) Long-term Flow Monitoring Reports and Records
In 2002, OCSD hired the consultant ADS to perform a Long-term Flow Monitoring
Program. This program involved using 150 flow meters strategically placed
throughout the overall Collection System for a period of two years from May 2002 to
May 2004. After which, the program was reduced to 75 flow meters from May 2004
to May 2007. This program was used to calibrate OCSD's computerized hydraulic
model and establish a baseline of flow measurements for each major trunk and flow
basin. Today, the long-term flow meters have been removed, and each major flow
basin or trunk has its flow metered by the permanent flow meters located at the two
treatment plants. Periodically, flow meters are placed for a special project or study
as needs arise, and new CIP projects are developed.
Capital Improvement Program (CIP) Projects Selection Process
1) Every other Fiscal Year, OCSD updates the AMP to better understand its short and
long-term business obligations related to the assets it currently owns and will own as
facilities needs change. The first AMP was developed in 2005 and has gone through
a number of refinements since then. This effort employs international standards for
asset management resulting in an "Overall State of the Assets" document.
2) OCSD has an open "Call for Projects" process which solicits issues and concerns
from the entire agency throughout the year. New project requests are brought to
OCSD's Project Clearinghouse Committee which decides if a new project is needed,
which Department/Division will lead the project, and what type of project it will be
(capital improvement project, maintenance, etc.). The proposed projects go through
an annual CIP Validation process to help prioritize the work and allocate the
necessary resources. These projects are tracked by the Engineering Planning
division until transferred to the Project Management Office for project execution.
3) OCSD reviews new and revises existing CIP projects annually. The effort prioritizes
projects based on need, risk, and overall cash flow of the agency. This effort has
been modified to utilize the principles of international standards of asset
3
management and business risk, which elevates the process to ensure future
repeatability.
4) OCSD has specifically addressed replacement and rehabilitation in its AMP. The
AMP supports the effort of determining the OCSD's cash flow needs.
Funding Process (Finance Department)
1) The funding process for Joint Operations Fund projects is done through a biennial
budget process involving each division reporting their needs to their division
manager who in turn prepares an operating budget submission and negotiates with
the Finance Department. The process is summarized in the "Operations Overview"
(Section 5) of the budget.
2) The funding process for CIP projects is done annually through a CIP Validation
process under the direction of the Director of Engineering. This process involves the
Project Management Division and the Planning Division. The results of the CIP
Validation process will be screened and validated through the Engineering
Department prior to being submitted to the Finance Department. The final listing and
summary of the CIP Budget for Capital Requirements is listed in OCSD's Budget
"Capital Improvements" (Section 8). This section includes a summary as well as a
detailed listing of each Collection System CIP project with projected costs over a ten
year period.
3) Funding in general is part of the budget process which is spelled out in OCSD's
Budget"Policies and Procedures" (Section 3).
Data Sources that Support CIP Funding and Project Selection
1) Collections O&M CCTV data (ongoing program)
2) Collections O&M Manhole Inspection data (ongoing program)
3) GHD Asset Management Model of Collection System
4) Planning Division Condition Assessment data (ongoing program)

VOLUME I December 13, 2016
SECTION 1 EXECUTIVE OVERVIEW
The Vision Statement for the Orange County Sanitation District is to maintain world-class
leadership in wastewater and water resource management. This vision also applies to
the way the Sanitation District manages its assets and facilities-world-class. To this end,
the District and more specifically the Information Technology-Enterprise Information
Management(EIM)group has expended significant resources—time and money—to
create, manage, and share systems, or facility models, that record the as-is state of the
assets and facilities. In order to manage these systems, which are in a constant state
of change, a process has been developed to ensure the data contained in the facility
models reflects the actual conditions in the field. This document describes the
procedures, standards and tools used in the process.
1.0 General Overview
1.0.1 Document Mission
The purpose of the facility model Maintenance Management Plan is to document
the process used to create, manage, and share the data contained within the
facility models. It also provides a high level understanding of the change
management process and provides a detailed understanding of the procedures,
standards and tools used by EIM staff. Not covered in this document are the
processes of adding new elements or features to the existing facility models or
creating new models.
1.0.2 Audience
The audience for this document consists of three distinct groups: regulators,
management, and editors. Regulators will see that there is a clearly documented
process, complete with procedures and standards, which ensure the Sanitation
District will remain in compliance with regulations. Management is assured that a
defined process is in place and is consistently applied. The editors will use the
document to follow the prescribed procedures, using the defined tools and
standards for day to day maintenance of the systems.
1.0.3 Assumptions
The process detailed in this document assumes the field staff personnel are the
ones who directly observe the accuracy and the correlation between the data in
the facility models and the actual observable conditions of OCSD facilities.
When the field staff submits discrepancy reports, the reports are accepted as the
as-is condition of the actual condition of the facility. However, if additional
information is required, the field staff may need to return to the location to collect
the necessary data.
1.1 Document Organization
This is Volume I of a 3 volume set of Information Technology Department,
Enterprise Information Management(EIM group) data maintenance process
documentation. The purpose of the documentation is to clearly detail the
processes used by the EIM group to maintain the facility models. The purpose of
Volume I is to provide a general overview and background on the EIM group and
Page 1-1
VOLUME 1 December 13, 2016
the facility model concept. Volumes II and III address the specific procedures
and standards for the each facility model.
Page 1-2
VOLUME 1 December 13, 2016
SECTION 2 FACILITY MODEL CONCEPT
A facility model is a complete and seamless representation of the current site conditions,
stored in a single location and intended for a particular use. These facility models are
used by OCSD staff, contractors and consultants to support the completion of work
activities, in support of the OCSD mission.
The facility model concept was developed to address the difficulties of managing a
growing volume of facilities information. A facility model provides a unique view of the
facilities for a specific purpose. As an example, the "Facility Atlas" (FA)facility model is
used to represent the physical location of process piping, equipment, and structures for
use in construction design and planning. The purpose of the"Plant Design System"
(PDS)facility model is to present schematic piping and instrumentation information for
use in process control and analysis.
2.0 Descriptions of Facility Models
2.0.1 Sewer Atlas/Electronic Map Book (EMB)
The Sewer Atlas Facility Model (SA)was completed in 2004 through Capital
Improvement Program project number 1-98. The SA is an electronic facility
model that includes all of the sewer lines, manholes, diversion structures, force
mains, siphons, force main valves and pump stations known to comprise the
OCSD sewer collection system. Data from the SA was used to populate the
current OCSD computerized maintenance management system (CMMS). These
systems are expected to remain synchronized.
The SA data can be viewed in a variety of methods. The SA is a GIB based tool
that is accessible through two web based applications, the Enterprise GIS and
the Electronic Map Book (EMB). The Enterprise GIS data used in the SA
provides read-only access to the assets for display and query purposes. The SA
is a seamless dataset; therefore tabular data on all stored assets is available as
needed. In addition, Record Drawings and Diversion Structures details are
linked and viewable directly from the assets.
The Map Books are a four-volume set of printed maps showing information
contained in the SA. These books are distributed to key locations and staff at
both plants and made available to crews working in the collection system.
The EMB is an online version of the printed map book with a means to link
directly to adjacent maps, Record Drawings and diversion structure details. The
EMB is also available in an of line format to be used on laptops not connected to
the District network.
2.0.2 Facility Atlas/Drawing Access System
The Facility Atlas (FA) is a powerful GIS-based tool for accessing "as-is"facility
information for both Plant 1 and Plant 2 through a map-based user interface.
The FA contains planimetric data; aerial photographs; design and construction
areas; and buried, above-ground, and in-tunnel utilities, and equipment.
The Drawing Access System (DAS) provides a means to link a map based
application directly to project information in the Electronic Document
Management System (EDMS). Users are able to select structures in either Plant,
VOLUME 1 December 13, 2016
and then query projects that built or affected that structure. Project details, such
as title and contract amount, and scanned engineering drawings may be viewed.
2.0.3 Electronic Document Management System (EDMS)
The Electronic Document Management System (EDMS) is a central repository
for all project-related documents including Record Drawings.
2.1 Change Management Approach
In general terms, there are two types of events that will trigger the Change Management
process: Capital Improvement Program (CIP) projects, and discrepancies. The following
is a high level description of the processes followed.
2.1.1 ICapital Improvement Program (CIP) ProjectiDR11
OCSD contracts with consultants and construction contractors to design and
build new facilities. These projects produce a set of construction drawings,
referred to as Conformed Drawings. Upon completion of the work described in
the drawings, Record Drawings are produced. The Record Drawings depict any
changes to the drawing set that occurred during construction. Those Record
Drawings are considered to be the final record of the work performed and the
current as-is condition of the facilities.
The Record Drawings have been deemed vital and historic documents and are
therefore maintained for the life of the facilities they constructed or modified. The
EIM group is responsible for their maintenance in both electronic and hardcopy
formats.
Upon completion of a project, Record Drawings are generally produced by the
design consultant. The plans are provided as electronic files in Portable
Document Format(PDF) and forwarded to the Engineering librarian. There they
are indexed and imported into the EDMS.
Copies of the Record Drawings are then distributed to key individuals to
determine if changes or updates are required of the facility models. This starts
the change management process.
For users of the data management applications, it is important to determine if
changes to facility models occur after Record Drawings are produced (occasional
exceptions have been made). This may, at times, result in data appearing to be
missing from the model. Many times this is because the construction work was
completed several months or years before the completions of the contractual
project and the production of the Record Drawings.
2.1.2 Field Discrepancies/Modifications to Existing Systems
The second type of classification of changes is referred to as"discrepancies".
These occur when the Feld condition does not agree with the facility model.
Examples include: manholes not shown on the Sewer Atlas; project data not
shown correctly, etc. These errors or omissions occur for many reasons:
oversights when extracting data for Record Drawings; incomplete or inaccurate
Record Drawings or undocumented field staff modifications.
Regardless of the reason, discrepancies detract from the accuracy of the model
and are therefore given high priority in regards to the change management
Page 2-2
VOLUMEI December 13, 2016
process. In short, the process consists of the OCSD staff filling out and
submitting a field discrepancy form. This form indicates the model in which the
discrepancy exists, and a description of the problem. This completed form, along
with any supporting information, Reoord Drawings, photos or sketches, etc. is
forwarded to the EIM group.
The discrepancy is logged, and evaluated. If the discrepancy meets the
deviation guidelines, it is processed and changes to the model are made. The
final outcome of the change is then forwarded to the requester to ensure we have
captured the discrepancy correctly as was seen in the field.

SECTION 3 STAFF ROLES AND RESPONSIBILITIES
3.0 Overview
The Information Technology's Enterprise Information Management (EIM)group was
established to be a centralized group of personnel who perform various administrative,
technical, design, and program functions in support of the Engineering Department. The
EIM group is responsible for maintaining certain features in the facility models. The
mission statement of this group is recording the"as-is"state of OCSD facilities by
capturing, maintaining, updating and sharing various engineering data sources.
Description of Staff Positions
3.0.1 GIS Administrator
The GIS Administrator will initiate and monitor the status of data versions and
perform quality assurance checks on work being performed by the GIS/CAD
Technicians. This staff member will also be responsible for posting final changes
to the Enterprise GIS, assisting in the resolution of data conflicts and upkeep of
the GIS based applications.
3.0.2 GIS Technician
The main function of the GIS Technician is to prepare data to be incorporated
into a facility models. The GIS Technician will work under the direction of the GIS
Administrator and/or FRG Lead. The tools used by this staff member may include
both CAD and GIS applications.
3.0.3 CAD Technician
The main function of the CAD Technician is to prepare data to be incorporated
into a facility model. The CAD Technician will work under the direction of the GIS
Administrator. The tool used by this staff member will primarily be CAD
applications.
3.0.4 Librarian
The Librarian is the individual responsible for the storage and safety of original
documents. In most cases these documents have been deemed vital and
historical and must be maintained in accordance with the Sanitation District's
records retention policies. The Librarian will be the primary recipient of incoming
Conformed and/or Record Drawings, specifications, reports, and final electronic
files.
3.0.5 Project Manager
The District Project Manager initiates requests for project data to begin a design
project, which also initiates a GIS data editing session. Once a database version
has been created, exported, and turned over to the District Project Manager, the
quality of the data edits are the District Project Manager's responsibility. The
District Project Manager must coordinate with Consultants, District Staff and
Contractors as necessary to ensure that edits returned to EIM at the closing of
the project and edit session, comply with the District CAD Manual.
Page 3-1
VOLUME 1 December 13, 2016
3.0.6 Consultant
Project consultants receive a district baseline model file to begin all CIP projects.
A data request is made through the PM for baseline model files and project
record drawing in the District EDMS. During the design phase of any project,
there are CAD standards reviews that must be completed in order to ensure
correct project data transfer. The consultant is to provide CAD files and hard
copy prints for review. CAD standards are enforced in order to assist in data
transfer and capture. Design data is converted from a CAD format to a GIS
format to be included in the facility models, which are then reused for future
project data requests.

VOLUMEI December 13, 2016
SECTION 4 SOFTWARE CONFIGURATION
A variety of software is used to implement and manage the Sewer Atlas/EMB and the
FA/DAS. The data for these systems is stored in an SQL Server database and a file
based system that can be accessed by a variety of CAD and GIS client software
packages.
4.0 Geographic Information Systems (GIS)
ArcGIS is the primary GIS client software used at the District and is distributed to
desktop viewers and editors. The GIS client application that publishes the FA, SA and
DAS on the District Intranet is called ArcGIS Server. ArcGIS Server sends data request
to the SQL Server database. It is also possible to connect directly to the SQL Server
database using ArcGIS desktop applications (which includes ArcMAP and
ArcCATALOG).
4.1 Computer Aided Drafting (CAD)
Autodesk CAD applications are the standard CAD design software at the District.
AutoCAD Map3D, Raster Design and Design Reviewer are a few of the software's that
are used for capturing and editing engineering data. Feature Data Object(FDO) is a
"middle-ware" that is used to allow CAD users to interface and edit GIS formatted data.
4.2 Engineering Document Management Systems (EDMS)
The Districts EDMS, SharePoint, is a software application that is the central repository
for all engineering project related documents. EDMS is an application that manages and
stores documents that are linked or accessed through either the FA/DAS or SA/EMB.

Volume III Sewer Atlas Maintenance
SECTION 1 PROCEDURES FOR SEWER ATLAS MAINTENANCE
1.0 General Procedures Overview
1.0.1 Document Organization
This is Volume III of a five volume set of Engineering Department, Engineering Data
Management Group(EDM group) data maintenance process documentation
(Document). The purpose of the document is to clearly detail the processes used by the
EDM group to maintain the facility models. The purpose of Volume III is to provide
background and detailed change management procedures for the Sewer Atlas Facility
Model. General discussion and background on the EDM group and the facility model
concept are presented in Volume I.
Volume III is divided into four sections. The first section lists the procedures required to
maintain the Sewer Facility Atlas Model. The second section provides Alternate Data
Collection Procedures if the required data is not available. The third section contains the
standards that are used to accurately perform the procedures. The Appendix in the
fourth section includes reference material such as forms and supporting documentation.
1.0.2 About Sewer Atlas (briefly)
The Sewer Atlas Facility Model (SA)was completed in 2004 through Capital
Improvement Program (CIP) project number 1-98. The SA is an electronic facility model
that includes all of the sewer lines, manholes, diversion structures, gravity pipes,
siphons, force main valves and pump stations known to comprise the OCSD sewer
collection system. For more detailed information on the SA, refer to Volume I, Facility
Model Maintenance Management Plan.
1.0.3 Sewer At/as Data Lifecycle
The sewer collection system is constantly undergoing change. As such,the SA requires
constant changes to accurately reflect the conditions in the field. When a change is
made to the physical collection system, or a discrepancy between the SA and the real
world is observed, a record of the changes or discrepancy is noted. Discrepancy
records are routed through the EDM group and, if necessary, changes are made to the
SA. Once changes are made to the SA, the corrected data must be published in a
variety of formats to provide access for OCSD staff. The details of the types of
discrepancies noted and the framework used to correct and publish updated information
is the focus of the remainder of this document.
1.0.4 Sources of Edits
Edits to the SA come from a variety of sources including CIP projects, discrepancies
noted in the field by collection systems staff and changes made to the system by
operations and maintenance staff. A brief description of these sources is included in this
section,for more detailed information, refer to Volume I, Facility Model Maintenance
Management Plan.
Capital Improvement Program (CIP) Project
A Capital Improvement Program (CIP) Project is a change to the collection system
managed by the Engineering department through the CIP project or Facility Engineering
project. For the purposes of this document, CIP projects and FE projects are referred to
1-1 8/18/2010
Section 1 Procedures for Sewer Atlas Maintenance
as CIP only. When a CIP project is completed, engineering Record Drawings are
produced recording the locations, sizes, and nature of concealed items such as sewer
lines, manholes, and the like. These drawings that detail changes to the collection
system are submitted to the Engineering department and, in tum, to the EDM.
Field Discrepancies
A field discrepancy occurs when OCSD staff using SA data identifies a discrepancy
between the SA data and the actual facilities observed. By identifying and correcting
field discrepancies, the SA data becomes more accurate over time.
Closed Circuit TV(CCTV)
CCTV has been used to identify error in OCSD GIB data
Periodic Updates
Periodic updates occur when the data in which the Sewer Atlas was built, such as
parcels, street centedines, etc. are updated by the originating source.
1.0.5 Altemate Data Collection Procedures
Section 1 details the expected sequence of events to update the Sewer Atlas Facility
Model. Occasionally additional steps must be taken before the process outlined in this
section can occur. If the required data is not on the Record Drawing, then it will be
necessary to perform Permit Research or Field Data Collection. The results of which are
documented on the Record Drawing, using the Record Drawing Process. These
procedures are detailed in Section 2, Alternate Data Collection Procedures for Sewer
Atlas Maintenance.

Section 1 Procedures for Sewer Atlas Maintenance
1.1 Prepare Work Package
When it is determined that the discrepancy or project does impact the Sewer Atlas and that the
required data is on the Record Drawing, then a work package is entered into the GIS Change
Management Tracking Spreadsheet and forwarded to the GIS Technician. The work package
consists of:
The completed discrepancy form or CIP Record Drawings.
A print of the map book page impacted.
A blank Sewer Atlas check list. Refer to Appendix 4.6, Change Management Checklist.
1.2 Locate and Print Record Drawings in EDMS
The first step for the GIS Technician is to locate, review and print the required Record Drawings
that are stored in the Electronic Document Management System (EDMS). Record Drawings will
contain the vast majority of the information required to make a change to the Sewer Atlas. To
extract this information it is necessary to print hardcopies. All Record Drawings are accessible
via the EDMS. If a Record Drawing is missing, it is imperative that the missing drawing be
brought to the attention of the Engineering Librarian. The following search methods are
available from the EDMS application:
1.2.1 Locating EDMS drawings
Some general guidelines for locating the drawings in EDMS are listed below. Refer to
the EDMS Desktop, Quick Reference Guide for details on locating documents in EDMS,
or Volume V, Tools for Facility Model Maintenance.
• Use Simple Search when the criteria required to locate a document are very
specific, such as Item ID.
• Use Advanced Search when multiple criteria are required to locate a document.
• Use Drawing Search when the search criteria are specific to engineering drawings.
1.2.2 Printing Drawings
Printing is allowed directly from the EDMS interface and is useful when printing a small
number of drawings (1 to 4). For larger numbers of drawings, it is recommended that the
AccXES Client Tool be used. Refer to Volume V, Tools for Facility Model Maintenance.
To print a single document:
• Using the search results, double-click the document title and select print.
Alternatively, select the title, right-click and select print.
To print multiple documents:
• Copy all documents from EDMS to a temporary location on the hard drive.
• Use AccXES Client Tool to submit the prints.
• Delete the files from the temporary directory when finished printing.
• Refer to Section 3.4, Printing Standards for Large Format Drawings.

Section 1 Procedures for Sewer Atlas Maintenance
1.3 Data Preparation
Data preparation is the process of reviewing the Record Drawings and project model files to be
used for the creation or modification of an OCSD asset or assets. The preparation of that data
improves the quality and efficiency of the data input process described in Section 1.6,
Create/Edit Features.
1.3.1 Record Drawing Preparation
This process consists of scrubbing or identifying information and data regarding an
OCSD asset or assets found on the Record Drawing. Items such as manhole location,
invert elevation, diameter, etc. are highlighted.
• If the Record Drawings have not been included in the work package or additional
drawings are required, refer to Section 1.2, Locate and Print Record Drawings in
EDMS.
• Review the work package to understand the work to be performed. It may be
necessary to review the CIP Record Drawing and/or the discrepancy form to get a
better understanding of the change(s)to be made.
• Highlight the asset information. Refer to Section 3.5, Data Preparation Standard.
• Some attributes are mandatory and therefore it may be necessary to calculate or
estimate the values.When doing so the attribute value must be written on the
Record Drawing and highlighted.
1.3.2 Project Model Files
If the work package consists of a CIP project, a project model file will be available. The
project model file will be used to locate the physical asset, while the Record Drawing will
be the source of the attribute information.
• Refer to the CAD Manual, Section 3.0 File Organization Techniques and Section 4.0
Directory Organization for a description and proper location of the project model file.
• Launch AutoCAD and open the project model file.
• Isolate the desired CAD features by turning off extraneous layers and/or deleting
unnecessary objects.
• When complete, save CAD the file to the working folder. Refer to Section 3.8.3,
Working Folder Standards and 3.8.4, Working File Standards.

Section 1 Procedures for Sewer Atlas Maintenance
1.4 Establish Asset Numbers
Each asset within the OCSD collection system requires an asset ID. The EDM group is
responsible for creating the assets and subsequently the asset ID. The following are the current
numbering conventions in use.
1.4.1 Manhole Numbering
Each manhole within the OCSD collection system is uniquely identified. The Manhole
Numbering Standard can be referenced in Section 3.7.1, Manhole Number Convention.
The following procedure is intended to prevent the duplication of manhole IDs.
Inserting manhole on trunk
Open the Master MPG Object Data database. Note: In order to keep the
' master MPG Object Data
• Open the Manhole table. database current, the GIS
• To reduce the number of records it may be helpful Administrator will be
to filter the manhole table by trunk abbreviation. required to periodically
• Sort the table by the STRUCT_1 column. export the contents of the
Master File.
• Find the highest trunk sequence number. Do not
rely on the current map book page to determine the highest trunk sequence number.
• Number the manhole by incrementing by 5, unless the new manhole is inserted
between two existing manholes.
Inserting manhole on a lateral
• Follow the steps listed above.
• Find highest lateral sequence for the entire lateral. Do not rely on the current map
book page to determine the highest lateral sequence number.
• Number the manhole by incrementing by 5, unless the new manhole is inserted
between two existing manholes.
Inserting manhole between two existing manholes
• Divide the space by 5.
• Identify the point closest to the new manhole location.

1.4.2 Gravity Sewer Line Numbering
Each sewer line within the OCSD collection system is uniquely identified within CMMS.
A sewer line is made up of a downstream manhole and an upstream manhole joined
together to establish the pipe id. EDM staff are not responsible for concatenating the
downstream and upstream manholes to form the pipe id. However, EDM staff are
responsible for populating the sewer table with the STRUCT_2 and STRUCT_1 values.
The Sewer Line Numbering Standard can be referenced in Section 3.7.2, Gravity Sewer
Line Numbering.
• Create the manholes. Refer to Section 1.6, Create/Edit Features.
• Draw the sewer line using the MPG. Refer to Section 1.6, Create/Edit Features. This
will create the sewer line but it does not establish the asset numbers.
• To populate the sewer table with the appropriate STRUCT_2 and STRUCT_1
values, the object data must be exported to the Object Data Database where a
series of queries are run and then imported back into the working file. It is not
necessary to perform this function right away; it can be done during the 1.10, Data
Exchange.
• Export the manhole table and sewer tables. Refer to Section 1.10.1, Exporting Data.
• Open the Object Data database and run queries qry-1, qry-2 and qry-3. These
queries will move the data from the manhole table to the sewer table to populate
STRUCT_2 and STRUCT_1 properties.
• Import the sewer table back into the working file. Refer to Section 1.10.2, Importing
Data.
• Caution: The definition of a sewer line is; a segment of pipe which has an asset at
each end. In other words the sewer line must have a manhole or pump station at
both ends. The procedure described above will, most likely, introduce bad data into
the working file. It is imperative this does not get introduced into the master file. This
can be avoided by closely following the procedure defined in Section 1.14, Commit
Edits to Master File.
1.4.3 Bypass Line Numbering
Each sewer line within the OCSD collection system is uniquely identified within CMMS.
There are however unique situations where two or more lines connect to the same
downstream and upstream manholes. Siphon and vent lines are examples of these
unique situations. EDM staff are not responsible for the creation of the pipe id for bypass
lines. However, EDM staff are responsible for correctly identifying a sewer line as a
siphon or vent. This information is used by CMMS to create the pipe id.
1.4.4 Force Main Numbering
A Force Main is a sewer pipeline carrying wastewater or treated effluent in which the
flow in the pipeline is dependent on and driven by a pump station. Each Force Main
within the OCSD collection system is uniquely identified within CMMS. The force main ID
changes when it encounters a physical asset such as a manhole or valve. Changes in
direction do not constitute a physical asset and therefore do not affect the force main ID.
The Force Main Numbering Standard can be referenced in Section 3.7.4, Force Main
Numbering.
1-7 8/18/2010
Section 1 Procedures for Sewer Atlas Maintenance
1.4.5 Force Main Valves and Air Valves
Force Main Valves and Air Valves are numbered by CMMS. OCSD standard practice is
to request looptag numbers during the design phase of the project and document them
in the Record Drawings. If this has not been done, contact CMMS and request the
creation of the looptag number.
1.4.6 Pump Station Number
Pump Stations are numbered by CMMS. OCSD standard practice is to request Pump
Station numbers during the design phase of the project and document them in the
Record Drawings. If this has not been done, contact CMMS and request the creation of
the Pump Station number.
1.5 Create Working File/Folder
The working file is created by extracting elements from the Master File to be modified within a
map book page. It is necessary that all elements within the grid or grids to be included in the
working file. This extra information will be used later to update the manhole table and other
associated activities. The working folder contains all the files created during the update
process. Refer to Volume V, Tools for Facility Model Maintenance, for detailed information on
how to use the AutoCAD attach and query commands.
The process is as follows:
Create a new drawing file using the template defined in Section 3.8.1, CAD Template.
If the OCSD-GRID is not attached, attach it as an external reference file.
Attach the Master File using the AutoCAD Map command.
If the work is for a CIP project, attach the prepared project model file. Refer to Section 1.3.2,
Project Model Files.
Identify the map page and define the query parameters.
Save the working file. Refer to Section 3.8.3, Working Folder Standards and Section 3.8.4,
Working File Standards.
1-8 8/18/2010
Section 1 Procedures for Sewer Atlas Maintenance
1.6 Create/Edit Features
This process utilizes a custom data "IUMNIIIIIIII
software raapplication to increase input the speed
and accuracy of the data input
The tools, referred to as the Map Product
Generator or MPG, were developed in
Visual Basic 6.0 and use Active X controls Spatial Update
to load attribute data from a simple user
interface into AutoCAD Map object data Digitizer Form
tables. A data dictionary is used to
populate drop down lists with allowable values and to validate entered data, with the intent to
reduce data input errors and eliminate duplicate data. Refer to Volume V, Tools for Facility
Model Maintenance, for detailed information on how to use the MPG tools.
1.6.1 Digitizer Form
The digitizer form is the primary input tool and will be used extensively. The tool controls
the creation of manholes, sewer lines, force mains and force main valves.
• When creating assets use coordinates, station and offsets, dimensions, etc. to locate
the proposed location of the asset. Use temporary construction elements as
necessary.
• If using a project model file, verify that the model aligns with the correct coordinate
system before creating assets.
• Manholes must be created first. Note: Never delete
assets. Cut and paste
1.6.2 Spatial Update them into the demo file.
The spatial update form is used to update or edit the
location of existing objects as well as object attributes.
1-9 8/18/2010
Section 1 Procedures for Sewer Atlas Maintenance
1.7 Abandoned Features
An abandoned feature is a manhole, sewer line, etc. wherein the physical object remains in the
ground but is no longer in service. The GIS Technician is not responsible for determining
whether a feature can be returned to service or for evaluating the method used to take the
feature out of service. The Record Drawings are taken at face value and abandoned features
are modified as indicated.
The process to abandon a feature crosses several individual procedures. The following is an
overview with references to the individual procedures or standards as necessary.
Move the abandoned manholes and sewer lines to the appropriate abandoned layer. Refer to
Section 3.10.1, Layer Convention.
Modify the manhole and sewer object data table. Refer to Section 3.10.3, Object Data.
Delete the sewer label and flow arrow.
Hatch the abandoned sewer line. Refer to Section 3.10.2, Graphic Elements.
Add annotation "ABANDONED (project A, project B)". Project A is the project that constructed
the sewer line and Project B is the project that abandoned the sewer line.
Export the manhole table and sewer table. Refer to Section 1.10.1, Exporting Data.
Open the Object Data database, open the manhole table, and sort the table by the Status
column. Highlight and delete the manholes with a STATUS value of ABAND, DEMO or
DELETE. This will prevent these manholes from being included in the manhole table.
Commit edits to the master File. Refer to Section 1.14, Commit Edits to Master File.
Export the data for use by the Enterprise GIS and CMMS. Refer to Section 1.15, Data Transfer.

1.8 Demolished Features
A demolished feature is a manhole, sewer line, etc. that has been physically removed and no
longer exists in the ground. The GIS Technician is not responsible for determining whether a
feature can be returned to service or for evaluating the method used to demolish the feature.
The Record Drawings are taken at face value and demolished features are deleted from the
Master File as indicated.
This process is also applied to errors made during the original capture of the collection system.
For example, manholes and sewer lines that were mistakenly added to the Sewer Atlas and
have been verified as not existing in the field.
The process to remove a feature is:
Identify assets to be removed.
Modify the manhole and sewer object data table. Refer to Section 3.10.3, Object Data.
Delete the sewer label and flow arrow.
Export the manhole table and sewer table. Refer to Section 1.10.1, Exporting Data.
Open the Object Data database, open the manhole table, and sort the table by the Status
column. Highlight and delete the manholes with a STATUS value of ABAND, DEMO or
DELETE. This will prevent these manholes from being included in the manhole table.
Commit edits to the master File. Refer to Section 1.14, Commit Edits to Master File.
Export the data for use by the Enterprise GIS and CMMS. Refer to Section 1.15, Data Transfer.
1.9 Diversion and Splitter Structure
Diversion Structures and Splitters are documented in two locations, the map books and a
separate Diversion Structure book. Diversion and Splitter structure edits will typically occur
during CIP projects when new features are being added. A diversion structure is one where
slots or adjustable gates are present and flow can be directed or redirected from one trunk line
to another to control flow or capacity. A Splitter Structure also contains slots or adjustable
gates, but flow remains within the same trunk.
The process is the same for each type of structure:
The GIS Technician draws the detail of the structure. Note: In order to keep
The detail is submitted to the EDM Group Lead to assign an existing i
alias number. functioninng,g, the general
rule is to not rename the
To assign an alias number, locate the highest number and add map book page filename.
1.
The EDM Group Lead convenes a meeting of the Diversion Structure committee and submits
the detail for approval.
Upon approval, the detail is distributed to the owners of the Diversion Structure book by the
EDM Group Lead.
The detail then gets routed back to the GIS Technician to be incorporated into the Map Book.
Insert into open location on existing map book page or create a new map book page as
necessary.
Add a hyperlink from the Diversion Structure to the diversion structure map book page.

1.10 Data Exchange
r 1 r
The Data Exchange command of the MPG
is used to move object data between ag Sy
CAD file and an MS Access database. The hh�� ' `• a C� Y
exporting of data is a prerequisite for
several other activities such as updating of
the manhole table and updating the Data Exchange
hyperlinks on off-page connectors. The
importing of data is used to make global changes to data and to post-process certain attributes.
When exporting data, the contents of an object data table are written to a MS Access database.
The path to this file is preset and can not be changed. The primary key connecting the AutoCAD
objects with the database is the objects handle. AutoCAD controls the creation and modification
of the handles and they are subject to change.When planning to export and import data it is
imperative that special attention be given to the sequence of events. Refer to Volume V, Tools
for Facility Model Maintenance for additional information on exchanging data.
1.10.1 Exporting Data
• Drop all tables before exporting. This will delete any existing records in the table.
• Create the table and adjust the field lengths for manholes according to Appendix 4.0,
Field Lengths. For a manhole data exchange use the file located on the network;
J:\Facility Models\Sewer Atlas\Models\mh_field_sizes.xls
• Choose the data table to be exported and select the feature type.
• Export the data table.
• Repeat the process for additional data tables as necessary.
1.10.2 Importing Data
• If the data is to be modified and imported back into the object data tables, perform
the modifications or post-processing prior to closing the current AutoCAD session.
• Choose the data table to be imported.
• Import the data table.
1.11 Manhole Hyperlinks
The links between manholes and Record
Drawings are established by the very nature , r r
that the manhole is shown on the Record PM
Drawing. To add to the usability of theq ey Sy
electronic map book the manhole object is 4� z R• P
hypedinked to the Record Drawing. This is
done using a default path and the EDMS
Item ID or the scanned image filename (The Hyperlink Manhole
scanned image filename is used for an
offline version of the electronic map book).
The Hyperlink Manhole command of the MPG as well as the object data database is the most
convenient method to create and update the manhole hypedinks. Refer to Volume V, Tools for
Facility Model Maintenance for additional information on manhole hyperlinks.
Open the working file.
1-12 8/18/2010

1.13 Quality Assurance
Quality Assurance (QA) is the process of reviewing the work performed to confirm that it
complies with the procedures and standards that have been established. The QA is conducted
primarily by the GIS Administrator. However, it is important that others involved in the updating
of the Sewer Atlas be aware of the quality expected.
The process to prepare and review a work package for QA is shown in the following diagram.

1.13.1 Completeness Assessment
The completeness assessment is a visual inspection to determine if the original
discrepancy or CIP was addressed. For example, questions such as"Was the entire
project included? Did we capture every manhole? Is there a label for every manhole?'
must be asked. In addition, the QA provides a reality check by asking such questions as
"is the direction of flow accurate? "Is the slope correct?" It may be necessary for the
GIS Administrator to go back to the original discrepancy or project and compare the
updates to the original source.
1-14 8/18/2010
Section 1 Procedures for Sewer Atlas Maintenance
1.13.2 Graphic Standards Review
The Graphic Standards review verifies that the graphics follow general guidelines for
placement such as the location, direction and placement of labels and arrows to ensure
consistency and ease-of-use of the edited maps. Refer to Section 3.12,Annotation
Guideline.
Specific review comments are written directly on the item and global comments are
written on the side of the map. Post-it notes are avoided as are separate comments
sheets.
1.13.3 CAD Review
The CAD elements are verified by using the batch file checker in AutoCAD. The batch
checker will check layer names and fonts. The use of filters can verify whether the
symbols, blocks and layers meet standards. Refer to Section 3.8.2, CAD Standards File.
1.13.4 CSV Data Review(future)
The CSV data review utilizes an automated loading application and an Oracle database
to verify the accuracy of the data being loaded into CMMS. When an OD Database file is
placed in the bulkloader folder, an automated loading routine runs. This routine has been
designed not to load data that contains format errors. If errors are present, the
submission is rejected and returned to the GIS Technician for correction.
• Open the Evaluation Database.
• Check for load errors. Return to GIS Technician if necessary.
• Run the predefined content review reports. Investigate as necessary and return the
work package to GIS Technician if required. Refer to Section 3.14, QA Reports.
1.13.5 DWF Review
Before the final DWF file is copied to the server, the file must be reviewed. The review
verifies the following:
• The file was produced correctly.
• The map book page matches the printed copy.
• The off-page connectors are functioning.
• The manhole hyperlinks are functioning.
• The"last updated" date has been changed.
1-15 8/18/2010
Section 1 Procedures for Sewer Atlas Maintenance
1.14 Commit Edits to Master File
After the discrepancy or CIP has successfully completed the quality assurance procedure, it is
necessary to commit the edits to the Master File. These edits also need to be isolated for
preparation of data transfer tasks. Refer to Section 1.15, Data Transfer.
Open the working file.
Delete all elements that were not impacted by the work package. Save the file to a working edit
file. Refer to Section 3.8.4, Working File Standards.
Create a new working_demo file. Cut and paste all demolished or delete features into this file.
Refer to Section 3.8.4, Working File Standards.
Open the Master File.
Cut and Paste all assets to be replaced into the master demo file. It may be helpful to attach the
working_edit and working_demo file to the Master File to identify the assets to be replaced.
Copy and paste the contents of the working_edit file into the Master File.
Purge the Master File before saving and closing the file.
1.15 Data Transfer
Previously, the new and/or modified assets were isolated into working edit and working demo
files respectively. Refer to Section 1.14, Commit Edits to Master File.
The data contained in the working_edit file is exported to an ESRI shapefile format for use in the
enterprise GIS applications and CMMS. The data contained in the working_demo file is
exported to an MS Access database format for use in the district's CMMS application.
The import of data into the enterprise GIS application is the responsibility of the EDM group and
is included in this procedure. The importing of data into CMMS is the responsibility of the CMMS
group and is not included in this procedure.
1.15.1 Export to GIS
• Open the working edit file.
• Use AutoCAD Map export tool to export the contents to a series of shapefiles. Refer
to Section 3.8.6, Shapefi/e Standard for the appropriate grouping of information.
• Load the appropriate Saved Profile. Refer to Section 3.8.5, Data Transfer Profile and
to Appendix 4.1, CAD Layers to determine which profile file to use.
• Verify all parameters on Selection, Data, and Options tabs (i.e. object data, layers,
feature type, etc.)
• Export the data. Refer to Section 3.8.6, Shapefile Standard.
• These shapefiles can also be used for the Export to CMMS procedures; either as
individual dbf files or by importing into pGDB.

• Refer to the J-101 Procedures Manual.
1.15.5 Import Data into Geometric Network
• Refer to Discrepancy spreadsheet and Sewer Atlas Master Edits database.
1.16 Print Map Book Pages
There are two methods of producing the necessary print files depending on the number of map
book pages to be printed. Printing directly from AutoCAD is available when printing a small
number of files (1 to 3). For larger numbers of files, it is recommended that the AutoCAD
Publish command be used. Refer to Volume V, Tools for Facility Model Maintenance.
To meet the needs of the various users, 3 printer outputs need to be produced; full size (22xl7),
half size (11x17)and AutoCAD DWF. In addition a final hardcopy check print is required. Within
the AutoCAD application several page setups have been created to ensure consistency of the
final output. The page setups are:

SECTION 2 ALTERNATE DATA COLLECTION PROCEDURES FOR
SEWER ATLAS MAINTENANCE
2.0 General Alternate Data Collection Overview
Section 1 details the expected sequence of events to update the Sewer Atlas Facility Model.
Occasionally additional steps must be taken before the process outlined in Section I can occur.
If the required data is not on the Record Drawing, then it will be necessary to perform Permit
Research or Field Data Collection. The results of which are documented on the Record Drawing
using the Record Drawing Process.
2.1 Permit Research Procedure
Underdevelopment
2.2 Field Data Collection Procedure
The following procedures identify the tasks and the party(s) responsible during the change
management process of field discrepancies. This process can be initiated by the Collections
staff itself(start at 2.2.1) or by other OCSD staff and forwarded to Collections staff for data
collection/field investigation (start at 2.2.4). The procedures below describe the overall process.
2.2.1 Create Field Discrepancy Form
• Discrepancy Identified.
• Fill out Field Discrepancy Form.
o Enter General Information; date, name, extension #, map book page(s)/grid,
etc.
o Print Sewer Atlas Map Page from online Electronic Map Book (EMB).
o Locate and print project Record Drawing(s), use Sewer Atlas and/or EMB if
necessary.
o Enter Asset Information; manhole or pipe, manhole ID numbers, and Record
Drawing info.
o Enter Asset Location information; address and/or cross streets, and city.
o Provide brief description of action needed to correct discrepancy.
• Attach Record Drawing(s) and Sewer Atlas Map book page(s)to Field Discrepancy
form.
• Submit all documents for review and processing.
2.2.2 Review Discrepancy Form
• Determine K discrepancy has been previously identified.
• Review Discrepancy form for completeness and associated documentation (Atlas
page and Record Drawings), attach any missing information and provide any other
related info that may be helpful.
• Return to collections staff for missing information or forward to EDM (Engineering
Data Management)Administrator via inter-office mail for submittal.
If discrepancy can be processed without field data collection or GPS data collection then
work continues in Engineering for updates. If follow up survey or GPS data collection is
2-1 8/18/2010
Section 2 Alternate Data Collection Procedures for Sewer Atlas Maintenance
needed then field discrepancy is accepted and logged by EDM Administrator and
returned to Field Crew Supervisor for assignment of field crew personnel. Steps for this
process follow.
2.2.3 Generate CMMS Service Request

2.2.5 Collect Data
• Prior to any field data collection, determine if latest GIS basemap data has been
loaded into Trimble. If not, upload latest GIS base map data and GPS Discrepancy
DB.mdb (Geodatabase)to Trimble unit; follow the attached Data Upload to GPS
procedures.
• Drive to location of discrepancy.
• Set up traffic control as necessary, use appropriate safety procedures to prepare
area for data collection.
• Collect Data. Determine the best method for collecting data, GPS or manual
collection.
Data can be collected both manually and with the handheld GPS unit. If the GPS unit is
not available or not necessary then all data will be entered onto the Field Discrepancy
Data Collection Sheet manually.
Refer to Section 3.6, Field Data Collection Standards for the standards used for both the
manual and GPS approach to collecting data. Both the manual approach and using
GPS require the data to be entered correctly. The manhole and sewer data lists below
define what the acceptable data should be. The GPS procedures follow the attached
Data Collection Process procedures.
• Follow Data Transfer From Trimble to PC procedures that follow to transfer collected
GPS data back to PC for incorporation into edit process.

SECTION 3 STANDARDS FOR SEWER ATLAS MAINTENANCE
3.0 Standards Overview
The Standards listed below are intended as a general rule of thumb. It is not possible to create
standards that will fit every possible scenario. Instead, the intent of the Standards is to provide
rules for most of the tasks and guidelines for the exceptions that will arise.
Each Standard is related to a step in the overall process of maintaining the Sewer Atlas. Refer
to Section 1.0.6, Process Flowchart. In addition, the procedures for each step may reference the
standard as a rule or guideline to be followed during the course of action outlined in the
procedure.
3-1 8/18/2010
Section 3 Standards for Sewer Atlas Maintenance
3.1 Deviation Guideline
The Deviation Guideline is used to determine what constitutes a change to the Sewer Atlas.
3.1.1 Physical Location
Changes to the physical location occur when district staff identify that an object
(manhole)shown in the Sewer Atlas is not in the correct planimetric location.
Changes will occur when one of the following criteria is met:
• A manhole located in field is not shown in the model.
• A manhole is shown in the model but does not exist in the field. The use of a metal
detector or other investigation may be required.
• Sewer line alignment in the field does not match the model and can be determined
with some level of accuracy.
• Pipe length measured by CCTV differs from the map books by more than 12 feet.
3.1.2 Data
Changes to attributes are made when data elements such as pipe diameter are deemed
to be incorrect. These attributes are considered to be absolute and all errors will be
corrected. The following is a list of attributes that are the most likely to be updated. The
remainder consists primarily of system related attributes. Refer to Appendix 4.5, Object
Data Tables.
• Manhole ID
• Station number
• Project number or Contract Number
• Rim Elevation
• Manhole Depth
• Diameter
3.1.3 Omissions
Omissions consist of layers already included in the Sewer Atlas that are missing objects.
Examples include labels for schools, parks, etc. Items that are not already included in
the Sewer Atlas are considered enhancements and will be added on a case by case
basis.
3.1.4 CIP Projects
Changes caused by CIP Projects are derived from Record Drawings. The time delay
between receiving Record Drawings and incorporation into the facility model may be
substantial. The time delay must be taken into consideration when submitting a change
request or discrepancy form.
3.1.5 Miscellaneous
Miscellaneous changes may occur from a variety sources such as: ownership
agreements, easements, boundary modifications and production errors or
improvements. These changes will be evaluated on a case by case basis.

3.3 Minimum Data Required on Record Drawings
The first step is to review the Record Drawing to determine if there is sufficient data to start the
process or if Alternate Data Collection is required. The table in Section 3.5.2, Data Categories
details the mandatory attributes required to process a change to the SA.
3-5 8/18/2010
Section 3 Standards for Sewer Atlas Maintenance
3.4 Printing Standards for Large Format Drawings
When printing large numbers of drawings (5+) it is recommended that AccXES Client Tool be
used along with the following standards. Refer to Volume V, Tools for Facility Model
Maintenance.
Option MW

Transform Scale to Fit
Labels Filename % , Date %d
Print order Reverse
3.5 Data Preparation Standard
Data preparation is the process of reviewing the Record Drawings and project model files to be
used for the creation or modification of an OCSD asset or assets. Even when using a project
model file, the majority of data will come from the printed Record Drawing. When calculating or
estimating attributes values the resulting value must be written on the Record Drawing. If an
attribute value is unavailable or can not be determined, a default value of-9999 will be used.

DOWNSTREAM INVERT ELEVATION CD I Refer to Section 3.5.10
3.5.3 INSTALLATION DATE
The installation date or date of construction may not always be annotated on the Record
Drawing. Therefore, the following order will be used to identify the installation date.
• Date of construction, if clearly annotated. (The construction date may also be shown
on the connection permit)
• Record Drawing date, also referred to as the"as-built' date.
• Design date taken from the title block.
• Project date taken from the project cover sheet.
3.5.4 OWNER CODE
The owner code determines which manhole symbol, OCSD or OCSD-maintained, is
used as well as the color of the sewer line. Use the owner code of the manhole
downstream of the new manhole location.When adding a completely new sewer line
and manholes, the project number can be used to determine the owner code. If the
contract number is an OCSD project number it is most likely an OCSD sewer.
3.5.5 STREET CODE
To avoid multiple spellings and misspellings of a street name, the MPG and CMMS
utilize a controlled value list (CVL)that contains numeric values for street names. The
MPG hides the CVL from the user and only presents the street name. However, the
value or code is written to the object data table. As a result, this attribute must be
entered using the MPG and can not be manually entered directly into the object data.
3.5.6 CROSS-STREET CODE
Refer to Section 3.5.5, STREET CODE.
3.5.7 RIM-ELEVATION-CD
The manhole rim elevation may not always be annotated on the Record Drawing.
Therefore the following order will be used to identify or calculate the rim elevation.
• If the manhole depth and center invert elevation are available, add the manhole
depth to the invert elevation.
• Use the profile grid to estimate the rim elevation.
3-8 8/18/2010
Section 3 Standards for Sewer Atlas Maintenance
3.5.8 MH CNTR INV ELEV CD
The manhole center invert elevation is the primary invert elevation for attribute data. The
invert elevation may not always be annotated on the Record Drawing. Therefore the
following order will be used to identify or calculate the center invert elevation.
• If the upstream invert elevation is annotated, use it for both the center invert
elevation field as well as the upstream invert field.
• If the downstream invert elevation is annotated, use it for both the center invert
elevation field as well as the downstream invert field.
• If the manhole depth and center invert elevation are available, subtract the manhole
depth from the rim elevation.
• Use the profile grid to estimate the manhole center invert elevation.
3.5.9 UPSTREAM INVERT ELEVATION CD
Refer to Section 3.5.8, MH_CNTR_INV_ELEV_CD
3.5.10 DOWNSTREAM INVERT ELEVATION CD
Refer to Section 3.5.8, MH CNTR INV ELEV CD.
3.5.11 MANHOLE DEPTH
The manhole depth is a mandatory attribute and must have a value. The depth will be
calculated using the rim elevation and manhole center invert elevation. Refer to Sections
3.5.7, RIM ELEVATION CD and 3.5.8, MH_CNTR_INV_ELEV_CD 3.5.8 respectfully.
3.5.12 FIELD_216 (Doc ID)
Field_216 is used to hold the EDMS document ID (Doc ID). The Attribute is mandatory
and must have a value. The value is determined by locating the document in EDMS and
identifying the ID. Refer to Section 1.2.1, Locating EDMS drawings.
3.5.13 TIF NUM
TIF_Num is used to store the scanned image filename. This attribute is currently missing
from the MPG interface and therefore must be added directly to the object data table.
This attribute is mandatory to support the of line version of the EMB.
3.5.14 DATUM DESIGN
If the datum is documented on the Record Drawings, the datum must be captured. The
datum annotation is stored in a separate database and a code is entered into the object
data.
3.5.15 YEAR RECONSTRUCTED
The year reconstructed is populated when the manhole or sewer have been modified by
a CIP project. Raising manhole covers to grade, district staff modifications, etc. do not
warrant a change to this property.
3.5.16 ORIGINAL-CONTRACT NO
The original contract no is populated with the project number field in EDMS. It is
important that the value entered into this property matches exactly the number in EDMS.
3-9 8/18/2010
Section 3 Standards for Sewer Atlas Maintenance
One exception to this rule exists. When working with drawings that are part of the TSI
(Tustin Sewer Index)the drawing number is used in place of the EDMS project number.
3.6 Field Data Collection Standards
Data can be collected both manually and with the handheld GPS unit. If the GPS unit is not
available or not necessary then all data will be entered onto the Field Discrepancy Data
Collection Sheet manually. Refer to Appendix 4.7, Field Discrepancy& Data Collection Sheets.
The following are field data collection standards used for both the manual and GPS approach to
collecting data. Both the manual approach and using GPS require the data to be entered
correctly. The manhole and sewer data lists below explain what values are acceptable.
Manhole Data
3.6.1 Status
Check"INSRV" or"ABND". In-service if observing flow in the manhole. Abandoned if
manhole is plugged or no longer in service.
3.6.2 Distance from Existing Manhole(s)
This consists of the physical location of the object as measured from an existing
upstream and/or downstream manhole, both preferred. GPS coordinate(s)with one
control point will be sufficient.
3.6.3 Manhole Depth
If profile data on record drawing isn't complete then field staff will estimate the depth by
using the laser range finder to determine distance to top of shelf or bench and adding in
pipe diameter to get total depth. The accuracy will be approximately+/- one foot.
3.6.4 Manhole Type
Choose Diversion, Standard, Drop, Siphon or Vent. For Diversion, please identify where
slots are located within manhole, is. north, south, east or west.
3.6.5 Direction of Connection
This is a visual observation of city owned assets as they connect to OCSD manholes.
N, S, E, W, NW, SE, etc. are acceptable.
3.6.6 GPS Data Collected
Manually check"yes"or"no" on data collection sheet, if all or a portion of the data
collected is with GPS then check "yes". If yes is checked many of these fields listed will
be held as attributes of GPS points. This is an alert to EDM staff to look for and use
GPS data in the editing process.
3-10 8/18/2010
Section 3 Standards for Sewer Atlas Maintenance
Sewer Data
3.6.7 Status
Check"INSRV" or"ABND". In service if observing flow in the pipe. Abandoned if no
flow observed in the pipe.
3.6.8 Pipe Diameter
The diameter of the pipe will be determined from record drawings. If a record drawing is
not available, the diameter will be estimated by field observation. Confined space entry
will not be conducted.
3.6.9 Pipe Material
The material of the pipe will be determined from record drawings. If a record drawing is
not available, the material will be estimated by field observation. Confined space entry
will not be conducted. (i.e. VCP, DIP, PVC, CIP, CIPP, CONPVC, RCB, RCP, etc.)
3.6.10 Pipe Length
Taken from ground measurement from upstream to downstream manholes. Ideally,
GPS coordinates will be used to calculate distance.
3.6.11 Pipe ID
When collecting data regarding a pipe segment, it is required that 2 manholes be located
and their location provided, either GPS or manually measuring from an existing
upstream and/or downstream manhole. Identify upstream and/or downstream manhole
and associated Manhole ID from GIS or Atlas.

A demolished or"delete"file has been created that contains OCSD assets that have been
removed from the Master File, this includes abandoned manholes.
The file is stored in the Ji facility models\model\folder.
The filename is OCSD_C-Demo.dwg
3.12 Annotation Guidelines
The items below are guidelines to be used placing annotation such as manhole id, pipe labels,
etc.
If flow arrow will not fit between manholes and the flow can be determined from either upstream
or downstream of the pipe, delete it.
Blocks are never to be scaled unless they are in a balloon blowup.
By default, the flow arrow is placed at the mid-point of the sewer line. If the flow arrow is moved,
the pipe annotation and/or leader must still point to the flow arrow.
When placing manhole ID#'s or leaders, do not cross over sewer lines or other assets. Place the
annotation on the same side as the asset.
Before printing a map book page check for overlapping elements i.e.; pipe annotation, leaders
crossing, manhole ID's, street names, etc.
Manhole ID's should be placed horizontal.
Pipe attributes should be placed parallel to pipe. If not possible, place horizontal and use leader
to mid-point of line.
Easement dimensions should follow (parallel)to boundary.

\\Filer-1\sewermovies\
Although, securities have been set on this directory to a limited few, Administrators still have
modify and write permissions. Please ensure that your team does not add or edit files and
directories—as this will corrupt the relationship between this set of files and our CCTV
database.
The directory currently holds 12,236 video files. Files were originally stored in the
"TagNumbers" sub-directory organized by CD/DVD barcode number with the original filename
from the CCTV vendor. As we rename the original files, they are moved from the
"TagNumbers" sub-directory into the"SewerMovies" main directory by a batch program (which
also archives the original filename in our database). Over the next few days, all of the files that
remain in the "TagNumbers" directory(approx. 1000+)will be renamed and moved. The
naming convention for video files in the SewerMovies directory is outlined below.
Naming Convention
• Formerly videos had all sorts of names,some examples:
o MPEG_A_05242007_1206_1_1i.mpg
0 133+80_128+46_090430_ mpg
o KNT0455-0005_KNT0455-0e00_091210_26.mpg
o PC-N_DS-C_06e401_l.mp9
o OCSD C69440 050609_9_1a.mpg
o Tape1A.mpg
• Although, renamingthe video files is not necessaryfor oursystem and a future Wincan system
to work, it does make it easier for a user to find a specific video without having to search our
database—he or she can simply scroll to or search fora file in Windows Explorer.
• The new file naming convention looks like this(example): RED0420-0160_RED0420-
0000_20e4e107_e853_00101502.mpg
o The first two items in the name are the nodes or assets,where the survey started and
where it was intended to end, in this example,the survey was started at Manhole
RED0420-0160 and is intended to end at Manhole RED0420-0000(the survey may be
abandoned before reaching its intended end). Please not that files are not named
according to upstream and downstream manhole—but named according to survey start
and survey end.
o The third item is the survey date, in this example 20040107 is January 7' ,2004.
o The fourth item is the survey time, in this example 0853 is 08:53 AM.
o The fifth and final item is the video identification number,#101502,which is used in our
database to track specific video files and as a relation to future Wincan survey numbers.
o It's possible for some of the above information to be unavailable,e.g.the start/end
assets,date or time-which can result in one of the following(note the video number is
always available, i.e.all videos have a number):
• --------------------------2e0401e7_e853_09181502.mpg (No

DATE: October 8, 2014
SUBJECT: System Evaluation and Capacity Assurance Plan
Introduction
This System Evaluation and Capacity Assurance Plan (SECAP)follows the General Waste
Discharge Requirements (WDR) sequentially; that is, each section of the SECAP is
presented in the order of and corresponds to a specific sub-section in the WDR which
allows the reviewer and auditor to easily reference the WDR for further information if
necessary.
The goal of the SECAP is to develop user-friendly documents for staff use, regulator use,
and public review as required by the WDR order. More detailed information can be
obtained from the individually referenced documents, but this submittal is designed to
specifically identify how the requirements of Section 13; sub-section viii (a) Evaluation, (b)
Design Criteria, (c) Capacity Enhancement Measures, and (d) Schedule are being met by
the Sanitation District.
Summary of the Sanitation District's Compliance
The Sanitation District has complied with the requirements of the WDR as is documented in
the following:
a) Evaluation - 2009 Facilities Master Plan (This document contains the latest short
term and long term capacity evaluations, the design criteria related to capacity
planning and information with respect to the urban runoff diversion program.)The
document is located on the Sanitation District's website and is available by
searching the document center.
b) Design Criteria -2009 Facilities Master Plan, OCSD Master Specifications,
Design Guidelines, and Standard Drawings (along with industry standards and
project specific inspection and test reports, these documents collectively form the
design criteria for Sanitation District projects).
c) Capacity Enhancement Measures - Pertinent documents include the following:
1) 2009 Facilities Master Plan (this document contains the latest short term
and long term capacity evaluations, the design criteria related to capacity
planning and information with respect to the urban runoff diversion
program)
1 of
2) FY 2014 - 2016 Budget, Adopted June 2014 (this document contains the
Sanitation District's Capital Improvement Plan). The document is located
on OCSD's website and is available by searching the document center
3) Operations and Maintenance Annual Report (This document contains the
sewer system's current performance including experience with capacity
related issues). The document is located on OCSD's website and is
available by searching the document center
4) Monthly Sanitary Sewer Overflows (SSOs) Report (this document is
prepared monthly and also contains the sewer system's current
performance including experience with capacity related issues). The
document is located at OCSD's Administrative Office in Fountain Valley
5) 2013-15 Asset Management Plan (this documentcontains longer term
capital and finance planning for the Sanitation District).
d) Schedule - FY 2014 - 2016 Budget, Adopted June 2014 (This document contains
Sanitation District's Capital Improvement Plan.)The document is located on
OCSD's website and is available by searching the document center.
Each of these documents are on-file with the Sanitation District's Board Secretary,
and available for review during business hours. The Operations and Maintenance
Annual Reports and the Monthly SSOs Reports have previously been submitted to
the Regional Water Quality Control Board.
Specific Demonstration of the Sanitation District's Compliance
WDR Section 13 viii(a) Evaluation:Actions needed to evaluate those portions of the
sanitary sewer system that are experiencing or contributing to an SSO discharge caused by
hydraulic deficiency. The evaluation must provide estimates of peak flows (including flows
from SSOs that escape from the system) associated with conditions similar to those causing
overflow events, estimates of the capacity of key system components, hydraulic deficiencies
(including components of the system with limiting capacity) and the major sources that
contribute to the peak flows associated with overflow events
The Sanitation District has a program that evaluates the capacity in the collection
system every five to ten years. This program is currently the responsibility of the
Sanitation District's Engineering Planning Division. The program includes
assessments of urban runoff, inflow, and infiltration during both wet weather and dry
weather periods. This program is used for capital improvement plan budgeting and
setting user fees.
The Sanitation District's 2009 Facilities Master Plan contains the steps and
assumptions for the evaluation of the sewer collection system. This document
includes the approach for estimating capacities, deficiencies, and a characterization
of the flow components contributing to the sewer system for the Years 2005, 2010,
2020, 2030, and Ultimate Buildout Conditions. The Sanitation District's evaluation
2 of
was done for dry weather and wet weather flow conditions. Assessments of inflow
and infiltration for both flow conditions were conducted as part of the evaluation. It
should be noted that a 10-year design storm was utilized which reflects OCSD's high
level of service goals. Although the design criteria used in the capacity evaluation is
more conservative than the current regulations, it does not specifically determine the
volume of the potential SSOs. The capacity model was calibrated using five years of
continuously monitored flow meters in the collection system. Where deficiencies
were found, improvements were recommended and prioritized for the Sanitation
District's Capital Improvement Plan.
The Sanitation District administers dry weather urban runoff diversions to the
sanitary sewer system. Each dry weather connection must be approved by the
Board of Directors prior to connection. This is a permit based program and hydraulic
flow and capacity issues are assessed on a case-by-case basis as part of the permit
review and approval process.
The program identified in the 2009 Facilities Master Plan is validated annually using
a variety of data sources, including closed circuit television recording, field
inspections, and when applicable flow monitoring results and local agency
development planning information. This check is conducted to determine if projected
flow increases are materializing as planned. The following table is a summary of
OCSD's planned collection system capacity capital improvement projects.

Note: This table is specific to the collection system and is not inclusive of all planned
capital improvement projects(for example the table does not include projects associated
with treatment plant processes). As such, the Sanitation District's Capital Improvement
Plan (CIP), which is included in the budget, may be inconsistent with the schedule in the
fable depending on the agency's priorities and resources.
3 of
WDR Section 13 viii(b) Design Criteria: Where design criteria do not exist or are
deficient, undertake the evaluation identified in (a) above to establish appropriate design
criteria
The design criteria used in the 2009 capacity evaluation was based on the National
Permit Discharge Elimination System (NPDES) permit requirements to eliminate the
occurrence of SSOs. Sewers larger than 12 inches in diameter were determined to
be deficient where the model showed a surcharge of greater than two (2)feet,
unless the surcharging was at least 10 feet below the ground surface or the system
was designed to operate under a surcharged condition, without an SSO occurring,
during peak dry weather and peak wet weather flow conditions for 2005, 2010, 2020,
or 2030.
Smaller sewers were determined to be deficient when the ratio of the peak depth of
flow to pipe diameter(d/D)was equal to 1.0 (indicating that the pipe was full). The
trigger for capacity concerns is lower for smaller pipes because they are generally
more affected by blockages and hydraulic inefficiencies such as offset joints. This
allowed capital improvement projects to be scheduled and completed before SSOs
would occur due to capacity restrictions.
When redesigning sewers larger than 12 inches the desired ratio of the peak depth
of flow to pipe diameter(d/D) is equal to 1.0. For sewers with a diameter of 12
inches or less the desired d/D is equal to 0.75. As with all design criteria, the
parameters listed here as well as the information provided in the master
specifications and standard drawings are guides. Each design will address project
specific limitations and may not meet the strict bounds of the criteria above.
WDR Section 13 viii(c) Capacity Enhancement Measures: The steps needed to
establish a short- and long-tens CIP to address identified hydraulic deficiencies, including
prioritization, alternatives analysis, and schedules. The CIP may include increases in pipe
size, ///reduction programs, increases and redundancy in pumping capacity, and storage
facilities. The CIP shall include an implementation schedule and shall identify sources of
funding
The Sanitation District's 2009 Facilities Master Plan identifies both short-term and
long-term capital improvements needed to address identified hydraulic deficiencies.
This includes a prioritization, alternatives analysis, and proposed schedules.
The Sanitation District's CIP is incorporated into the agency's annual budget cycle.
The validation process consists of evaluating existing and certifying new CIP
projects for the next ten year period.
As a part of the budget validation process the Operations and Maintenance (O&M)
Department develops a budget for the short and long-term renewal and replacement
(R&R) maintenance project program. Included in the R&R program are activities or
projects that arise out of either 1) the on-going pipeline and manhole inspection
program, or 2) lessons learned from operating, maintaining, or actively responding to
SSOs. Operations and maintenance activities are detailed in the Operations and
4 of
Maintenance Annual Report and SSO response activity is detailed in the Monthly
Sanitary Sewer Overflows (SSOs) Report.
The Sanitation District has also prepared an Asset Management Plan (2013-15) that
is used for longer term capital planning of facilities. This document includes
estimates for the capital program, but not specific projects, through the Year 2106.
WDR Section 13 vifl(d) Schedule: The Enrollee shall develop a schedule of completion
dates for all portions of the capital improvement program developed in (a)-(c) above. This
schedule shall be reviewed and updated consistent with the SSMP review and update
requirements as described in Section D. 14.
The Capital Improvement Plan (CIP) and the Sanitation District's budget is updated
and approved by its Board of Directors annually. The active projects in the CIP are
described in detail in the budget book. Significant changes in the project scope
and/or implementation schedule are noted within the project's justification within the
budget book.

1. PURPOSE AND SCOPE
The purpose of the Laboratory, Monitoring & Compliance (LMC) Sanitary Sewer
Overflow (SSO) Response Procedure is to establish an efficient spill response plan and
reporting procedure to ensure prompt notification and documentation to appropriate
public agencies of an unauthorized release of wastewater(raw or treated sewage or
industrial wastewater). This procedure augments the existing Sanitary Sewer Overflow
Notification Procedures SOP by further clarifying LMC staff's role in responding to
SSOs. It also clarifies general responsibilities of LMC staff in regards to spill response
and reporting responsibilities.

NOTE: Regulatory and other affected agencies require initial notification as soon as
possible (no later than two hours).
A. SSO Notification Process (Working Hours and Non-Working Hours)
1. An SSO call is answered in the Control Center (CC). The CC will send an email
describing the SSO through the "Spill Notification —Sewage with PNA" email
distribution list.
• The RWQCB, OCHCA, and OC Public Works are always notified through
the "Spill Notification — Sewage with PNA" email distribution list.
The email should include:
• The location of the SSO.
• The size of the SSO as determined by Collections O&M staff.
o Small (<1,000 gallons), medium (>1,000 gallons), large (>10,000
gallons).
• If the SSO entered a storm drain.
• The responsible agency of the SSO and if they have been notified.
LMC Sanitary Sewer Overflow Response Page 3of 10 Revised: 11 -02-16
Procedure Procedure No.LMC-SOP-008
o OCSD, city, or private property.
o If they are in transit to SSO site.
2. Confirm SSO email by calling CC at x7025.
• Confirm SSO email and request for updated information.
• If primary spill responder does not confirm receipt of email with CC, they
will contact primary responder by phone. If not reached CC will call
through the LMC Contact Information order until a spill responder is
contacted (Attachment A).
3. If the SSO is not OCSD's responsibility,
• Confirm with CC that they have spoken with the responsible agency and
that they are responding to the SSO.
• OCSD does not need to complete a CIWQS SSO Reporting System report.
4. If the SSO is OCSD's responsibility call appropriate regulatory agencies to
confirm they have received the email notification and update them with any
new information (Attachment B).
5. During non-working hours, LMC will make the appropriate notifications.
B. SSO Field Visitation
1. Visit OCSD SSO site based on the following criteria.
• When CC states that an Incident Command System is implemented. This
is usually based on the following:
o SSO volume greater than 10,000 gallons.
o The volume of sewage that entered the storm drain system was
greater than 1,000 gallons and occurred during working hours.
o Significant threat of impact to receiving waters.
o Significant threat to public health.
o Water quality monitoring plan is required.
• When OCHCA, RWQCB, OC Public Works or the media are on site or
have requested information that is not readily available from field staff.
• LMC may, at their own discretion, visit other SSO sites.
2. Upon visiting an SSO site, communicate with the regulatory agencies that are
on site or by phone.
• Update regulatory agencies with new information.
o Person reporting SSO
o Agency responsible for SSO
o SSO start time and SSO end time
o Containment information
o SSO volume, SSO volume contained, SSO volume lost
o Component where spill occurred
o Cause of SSO
o Final destination of sewage
o Notifications made
o Description of all water quality sampling activities conducted
including, if available, results and evaluation of the results.
o Detailed location map illustrating all water quality sampling points.
• If the media is present and it is an OCSD spill, contact Public Affairs as
they are responsible for communicating with the media.
LMC Sanitary Sewer Overflow Response Page 4of 10 Revised: 11 -02-16
Procedure Procedure No.LMC-SOP-008
3. Use LMC Spill Response Field Report to document observations and
discussions with regulatory agencies and media (Attachment C).
• Confirm the observations on the CIWQS SSO Reporting System report
with the LMC spill response field report.
• This information is secondary to the information that Collections
0&M staff should also be collecting.
4. Contact OC Public Works to determine if SSO can be contained in the flood
control channel.
• If the SSO has entered a storm drain OC Public Works will be able to
assess if containment is feasible in the flood control channel.
• If requested contact CASC Contractors to contain and recover SSO in
flood control channel.
5. Using the maps (OC Water Quality Monitoring Locations Map or the online
map (http://ocwatersheds.com/programs/ourws/) determines the path of the
SSO from the storm drain to the recreational water that it impacts.
• If the SSO is proven to not enter recreational water then no beach
closure can be issued by OCHCA.
C. SSO Reports
1. A Category 1 or Category 2 or Category 3 report through the CIWQS SSO
Reporting System is required to be submitted after an SSO has occurred
(Attachment B).
• No SSO Occurred
o A No Spill Certification report through the CIWQS SSO Reporting
System is required to be submitted within 30 days after the end of the
calendar month in which no SSO occurred.
2. The designated SSO Collections O&M staff will compile the Category 1 or
Category 2 or Category 3 report package and enter the information into the
CIWQS SSO Reporting System.
• The report package consists of these items.
o Problem report, field report, field sketches, maps, spill photos,
spill calculations, and pertinent email.
• Collections O&M field staff completes the field report, takes
pictures, maps, and sketches can be found at the ECAP SSO
site.
• Collections engineering staff completes the spill calculations.
• For references of previous SSOs, the database problem report
and monthly spreadsheet report can be found at the ECAP SSO
site.
3. Receive the information required for the Category 1 or Category 2 or Category 3
report from designated SSO Collections staff.
• Category 1 report package will be provided within 2 business days.
• Category 2 report package will be provided within 2 business days.
• Category 3 report package will be provided on the second week after
the end of the calendar month in which the SSO occurred.
4. Verify and update the information contained in the CIWQS SSO Reporting
System using the Category 1 or Category 2 or Category 3 report package.
• If any information is missing, contact designated SSO Collections O&M
LMC Sanitary Sewer Overflow Response Page 5of 10 Revised: 11 -02-16
Procedure Procedure No.LMC-SOP-008
staff to obtain the information.
5. A Draft Report must be submitted through CIWQS within three business days
for all Category 1 and Category 2 reports using the "Submit Draft" button.
6. Once the final QA/QC of the Category 1 or Category 2 report has been
completed on the CIWQS SSO Reporting System, click on "Ready to Certify'
which will prompt the LRO that the report is completed and ready for their
certification.
• The Category 1 and Category 2 report must be certified within 15 calendar
of the SSO end date.
• A SSO Technical Report must be submitted within 45 calendar days after
the end date of any Category 1 SSO in which 50,000 gallons or greater are
spilled to surface waters.
7. A Category 3 report does not require a Draft Report, but can still be submitted if
required. Once all information is entered on the report, click on 'Ready to
Certify' which will prompt the LRO that the report is completed and ready for
their certification.
• This report must be certified within 30 calendar days after the end of the
calendar month in which the SSO occurred.
8. If requested, meet with the LRO, or designee, for final certification of the report
in the CIWQS SSO Reporting System and to answer any questions.
9. In the event the CIWQS SSO Reporting System is not functional the SSO report
must be faxed to the Santa Ana Regional Water at fax (951) 781- 6288
according to the time schedules. Afterwards, the SSO report must be entered
into the CIWQS SSO Reporting System as soon as it is functional again.

3. RESPONSIBILITIES OVERVIEW
A. Public Affairs: Receive and respond to phone calls from the media or general
public related to SSOs. Visit an SSO site when media is present. Notify cities, fire
departments, police departments, etc. of SSOs when public relations are
warranted.
B. Information Technology: Work with Collections O&M, LMC and Plant No. 1
Operations staff to resolve problems with Internet/Network connection when non-
operational. Once the Internet/Network is operational, relay the information to the
appropriate division.
C. Risk Management: Responds to ensure that the safety of responders and the
public is not compromised while carrying our response operations. Risk
Management provides critical support with SSOs, and emergency operations center
activations including establishing an incident command post in the field.
D. Collections O&M: Division responsible for the SSS WDR to develop, implement,
maintain a preventative maintenance program, and certify SSO reports. Respond
to reports of possible SSOs from OCSD's facilities; Contain and coordinate the
cleanup of OCSD SSOs, including making every effort to recover sewage from the
storm drain before it reaches a surface water; Document actions taken using field
reports, pictures, maps, etc.; Assist member agencies when possible and

Procedure No.LMC-SOP-009
document actions; Deal directly with private property owners, this does not
necessarily mean field staff but individuals should be instructed to contact
supervisors/management if they have specific questions. The manager is a
designated LRO that can certify SSO reports.
Also responds to reports of possible SSOs that may involve industrial process
waters and document actions taken. Responsible for the Water Quality Monitoring
Requirements collection of SSO samples from SSOs to surface waters in which
50,000 gallons or greater are spilled to surface waters. This includes collections of
SSO samples, labeling of samples, delivery of samples to the Lab, replenishing
Water Quality Sampling spill kit supplies, and documenting the sampling.
Compile all SSS WDR required SSO information, including field reports, pictures,
maps, problem reports, and submit package to LMC staff in a timely manner for
review (i.e. For a Category 1 and 2 report, submit information by the second day.
For a Category 3 report, submit information by the 15� of the following month).
E. Laboratory, Monitoring, & Compliance (LMC -Compliance): Liaison with
regulators and SSS WDR compliance overseer. Assure regulatory agency
notifications and any additional necessary notifications are fulfilled. Visit SSO site
as required in the LMC Sanitary Sewer Overflow Response Procedure, LMC-SOP-
008. Submits drafts of the Category 1, 2, and 3 SSOs to CIWQS for compliance
with the SSS WDR. Review SSO reports before certification by Legally
Responsible Official. Assist with SSO tracking and attend meetings to clarify
compliance related issues and requirements. Provide support by contacting CASC
contractors to respond to SSOs that enter flood control channels. Coordinate the
Water Quality Monitoring Requirements per Section 4; subsection F, with
Collections and Laboratory. Report the Water Quality Monitoring results from the
Laboratory to CIWQS.
F. Operations — Plant No. 1: Control Center: Coordinate SSO response by
receiving and processing preliminary information on possible SSOs. Notify
necessary divisions, member agencies, and regulatory agencies (after- hours) by
phone, radio, text (PNA)and numeric pagers, and e-mail as necessary. Document
actions by filling out the SSO report in the CIWQS SSO Reporting System. If the
CIWQS SSO Reporting System is down at the time of the SSO, complete the SSO
report on the appropriate CIWQS SSO Reporting System data sheet found in the
Collections System Binder and follow up by entering the data into the CIWQS SSO
Reporting System at a later time.
G. Laboratory, Monitoring, & Compliance (LMC - Lab): Receive water quality
samples from Collections 0&M staff on SSOs to surface waters in which 50,000
gallons or greater are spilled to surface waters. Perform analysis on water quality
samples. Report water quality samples results to LMC compliance staff. Supply
Collections O&M staff with water quality sampling spill kits when requested.
H. Member Agencies (Cities and Sanitation Districts): Respond to reports of
SSOs that may involve their Collections systems or private sewer systems that may
impact the municipal storm drain system. Contain and clean-up their respective
SSOs, protect their storm drains, and notify necessary regulatory agencies.
Sanitary Sewer Overflow Notification Procedures 3 of 17 Revised 11-M16
Procedure No.LMC-SOP-009
I. OC Public Works and Stormwater Co-permitees: Protect County and co-
penmittee stormwater conveyance facilities from illegal discharges (including
sewage). Provide support by contacting CASC contractors to respond to SSOs
that enter flood control channels.
J. Orange County Health Care Agency: Goal is to protect the public health from an
SSO including responding to SSOs and closing beaches and other recreational
waters.
K. Private Property Owner: Remove the blockage (e.g., call a plumber) and stop
using water that goes to the sewer until the blockage is removed. OCSD may
assist with containment and clean-up if sewage enters public right-of-way. Local
city or OC Public Works or OCHCA stonmwater code/ordinance enforcement can
assist with uncooperative owners. OCSD is not authorized and will not participate
in the cleaning of any privately owned lateral lines.
4. SSO REPORTING AND NOTIFICATION PROCEDURES
NOTE: Regulatory and other affected agencies require initial notification as soon as
possible without jeopardizing the response process (no later than two hours).
A. SSO Report Received
(1) Control Center staff shall initiate documentation of the reported SSO (who,
what, when, where, why) on a Spill Interview Form (Attachment A).
(2) Control Center staff shall determine whether the reported SSO is in the OCSD-
service area or is the responsibility of another agency using the Sphere of
Influence, Sewer Atlas, other available resources in the Control Center, and/or
with the assistance of Collections O&M staff.
B. SSO from OCSD Facilities
(1) If the Control Center determines that the possible SSO may be related to OCSD
facilities, Control Center staff shall contact and relay the available information
for investigation and/or control of reported SSO to the on-duty Collections O&M
Supervisor or Designee during the day shift or standby Collections O&M staff
during after-hours.
(2) Control Center staff shall notify OCSD staff and regulators of the possible SSO
via an Outlook e-mail and provide the available information to the Spill
notification - Sewage with PNA distribution list (see Attachment B for recipients
— includes internal, OCHCA, OC Public Works, and RWQCB staff). For small,
non-critical events (using the Operations supervisor's best judgment) when
reports are taken between 10 p.m. and 5 a.m., the Control Center staff may
utilize the Spill Notification - Sewage w/o PNA (Attachment B1 (no pagers are
notified). The following information should be included in the preliminary e-mail
notification if available:
• Responsible city, agency, private property owner
• Date and time
• Incident location including address and city
• Problem description
Sanitary Sewer Overflow Notification Procedures 4of 17 Revised 11-M16
Procedure No.LMC-SOP-009
• Response status
• If it entered a stone drain
• Estimated volume
(3) Upon arrival on site and preliminary investigation of reported SSO, Collections
O&M staff will confirm whether or not there is an SSO and the status of their
response and containment.
(4) Collections O&M staff will make sketches and take photographs of the SSO,
and they will forward digital files to the designated LMC staff.
(5) Control Center staff will send out intermittent updates as new information
becomes available to the Spill notification - Sewage with PNA subscribers.
(6) The on-duty member of the LMC staff shall notify OCHCA staff with a phone
call for any SSO volume (see Attachment C). If the SSO is equal to or greater
than 1,000 gallons also contact OES.
• During the night and weekend shifts: contact the County of Orange
Control 1 instead of OCHCA.
• Responsible staff shall complete all applicable regulatory notifications
in accordance with the Decision Table in Attachment C.
(7) Collections O&M staff or managers may request Control Center staff to contact
other staff that may be required. They may also request Control Center staff to
determine the location and direction of flow for storm drains in the SSO area.
This information is located on a set of 80 large County of Orange facility
drawings in the Control Center or online at OC Public Works website_
htto://www.ocwatershed s.com/watersh eds.asi)x
(8) Control Center staff shall create a service request number in the Maximo
System. Staff will then enter the SSO data into the CIWQS SSO Reporting
System or if it's non-operational on the appropriate CIWQS SSO Reporting
System data sheet found in the Collections System Binder and follow up by
entering the data into the CIWQS SSO Reporting System at a later time.
Control Center staff shall send updates to the Spill notification - Sewage with
PNA distribution list as information becomes available.
(9) When Collections O&M staff and Control Center staff believe the preliminary
information is as complete as possible for the response and clean-up (usually
after Collections O&M staff leaves the site), Control Center staff shall provide a
final notification of the SSO to the Spill notification - Sewage with PNA
distribution list.
(10) By the end of the reporting period, Collections O&M staff shall review the
Collections Field report and submit to LMC staff. LMC staff will make any
necessary changes and additions in the CIWQS SSO Reporting System.
When all changes are complete, LMC staff will click on the Ready to Certify
button so that the LRO can certify the SSO report for compliance. (see EC
Sanitary Sewer Overflow Response Procedure, EC-SOP-008)
C. SSO from Private Property
Sanitary Sewer Overflow Notification Procedures 5 of 17 Revised 11-M16
Procedure No.LMC-SOP-009
(1) Control Center staff shall notify and/or dispatch Collections O&M staff to
determine if the OCSD sewer is causing the problem.
(2) See Section B above. Response is the same. However, no field pictures,
sketches or calculations are required. Control Center staff shall note in the
CIWQS SSO Reporting System that the problem was a Private Property SSO.
Information provided in the CIWQS SSO Reporting System will include the
following:
• Responsible private property owner
• Date and time
• Incident location including address, city and zip code
• Problem description
• If it entered a storm drain
• Estimated volume
(3) If Collections 0&M staff informs Control Center staff that the blockage is located
in the private property owner's lateral, they will request the owner/property
manager to relieve the blockage (including calling out a plumber immediately if
necessary). Due to liability concerns and the possibility of damage to the
property owner's line in OCSD trying to solve the situation, it is against OCSD
policy for Collections O&M staff to work on private lines, although supervisors or
management may authorize this work on a case-by-case basis.
(4) If the property owner or the occupant of the property cannot be reached
or refuses to call a plumber AND the private property discharge is
entering the public right-of-way or a storm drain, LMC staff shall call OC
Health Care (714-433-6419) (Control 1 after hours— 714-628-7008) to
request health codelordinance enforcement assistance.
The County and the local cities are required by their NPDES permit to not allow
sewage to discharge to storm drains, and they have the legal authority to
enforce their requirements, which may include shutting off the water supply and
other measures.
(5) If a member of the public calls to report a reoccurring or ongoing SSO on
private property or that we cannot otherwise assist them, they can report the
problem by calling 24-Hour Water Pollution Problem Reporting Hotline 877-
891-7455 or logging onto htto://www.ocwatershed.com/and clicking on
Pollution Hotline. Staff can also use this mechanism, but official agency calls
should be made to Control Center.
(6) Control Center staff shall provide a final notification through Spill Notification -
Sewage w/o PNA (Attachment B) that the spill response has been completed.

a. Refer the problem to the correct agency.
b. Document the agency's name, contact person, time of contact, and phone
numbers on the internal Collections System Problem Report.
E. SSO NOT OCSD's Facility BUT Responsible Agency Requests Assistance
(1) Control Center staff shall notify and/or dispatch Collections 0&M staff, if
available.
(2) See Section B above. Response is the same. However, no field pictures,
sketches or calculations are required. Control Center staff shall note in the
internal Collections System Problem Report that the problem was not an OCSD
SSO.
(3) Provide notification through Spill Notification -Sewage w/o PNA (Attachment B)
as usual
F. Water Quality Monitoring Requirements— Sampling and Testing
Water quality sampling and testing is required to assess impacts from SSOs to
surface waters in which 50,000 gallons or greater are spilled to surface waters.
Sampling is conducted by the Collections O&M staff,testing is conducted by the LMC
- Laboratory staff, and reporting is conducted by LMC - Compliance staff. The water
quality monitoring requirements are listed below:
(1) In the event of an SSO that reaches a surface water and has a volume of
50,000 gallons or greater the Collections O&M staff will inform their Supervisor
and the Control Center that water quality sampling will be performed. The
Control Center will then notify appropriate staff(e.g. LMC spill reporting staff
who will coordinate the Water Quality Monitoring response).
(2) The Collections O&M staff shall use personal protective equipment (PPE)while
performing sampling and proceed only when it is determined to be feasible and
safe. The Collections O&M staff will be equipped with a Water Quality
Sampling spill kit (e.g. sterilized bottles, labels, and chain of custody form).
(3) The Collections O&M staff shall collect water quality samples from three (3)
locations in the receiving water in which the SSO entered:
i. 50 feet upstream of the SSO point of entry in the receiving water;
ii. At the SSO point of entrance in the receiving water;
iii. 50 feet downstream of the SSO point of entry in the receiving
water.
(4) Collections O&M shall photograph, map, and mark the location of the three (3)
sample locations for future reference in the field report.
(5) Collections O&M shall collect one (1) each of bacteriological water sample in a
special sterilized bottle from the upstream, entrance, and downstream receiving
water site. The sterile bottles can be found in the Water Quality Sampling spill

kit.
(6) Collections O&M shall collect one (1) each of ammonia sample in a special
sterilized bottle from the upstream, entrance, and downstream receiving water
site. The sterile bottles can be found in the Water Quality Sampling spill kit.
(7) Collections O&M shall label the six (6)field samples with the date, time,
location, and sampler's initials.
(8) Collections O&M shall keep the samples under ice until transferred to the OCSD
laboratory.
(9) Collections O&M staff will bring samples back to the OCSD Laboratory for
analyses and fill out the chain of custody form (COC) as soon as possible.
(10) Samples are assigned chain of custody forms that are completed throughout
the sampling, analysis, and reporting process.
(11) OCSD Laboratory staff shall log the samples into LIMS and analyze the six (6)
field samples for ammonia and appropriate bacterial indicator. Ammonia and
bacterial indicator analysis procedures are maintained at the Laboratory.
(12) The LMC - Laboratory shall provide the results of the analysis to LMC -
Compliance for inclusion in the SSO report.

SSO Emergency Response Plan
Description
December 19, 2011
Introduction:
This SSOERP follows the Statewide Waste Discharge Requirements (WDR).
After the State WDR was adopted on May 2, 2006, OCSD updated its existing SSMP
from the prior Santa Ana Regional Water Board WDR order to meet its new
requirements. OCSD currently has an effective SSO response program in place that
includes extensive notification procedures.
Volume 1 of the final SSMP includes a narrative summary of how OCSD complies with
the WDR or Monitoring and Reporting Program (M&RP). Volume 2 of the final SSMP
contains specific support documents referenced in Volume 1 needed for quick access
by staff or auditors.
Our goal is to develop user-friendly documents for staff use, regulator use, and public
review as required by the WDR order. This SSOERP also becomes a part of OCSD's
Integrated Emergency Response Plan (IERP) for major local or regional disasters.
OCSD has reviewed and updated its existing SSOERP. The SSOERP is illustrated in
the "OCSD SSO Response Flow Chart" (Appendix P1) that provides a step-by-step
description of the OCSD SSO emergency response procedures. The flow chart is also
designed to be used as a decision tool for responding to different types of events in
gravity sewers, force mains, and pump stations. Where appropriate, based on staff
input and professional judgment, more detailed flow charts, procedures, and other
referenced documents will be used as supplemental data.
OCSD SSOERP action items are as follows:
(1) Description of Organization:
(A) Administrative, Operations and Maintenance and Lines of Authority:
OCSD currently maintains organization charts that provide this information. Much of
this general information is available for review in our annual budget book. In addition,
an SSMP program organizational chart is maintained.
The Collection Facilities O&M Division staff have the lead role in SSO response
activities and retain current versions of SOPs for SSO Response and Spill Containment.
Other agency staff and contractors assist them as necessary.
(B) Chain of Communication for Reporting SSOs:
The chain of communication for reporting SSOs, from receipt of a complaint or other
information, including the person responsible for reporting SSOs to the RWQCB, the
1 of
Orange County Health Care Agency (OCHCA), Orange County Public Works, and the
State Office of Emergency Services (OES), is contained in Appendix P, Volume 2.
These include the SSO Response flowchart that describes the OCSD Control Center
and Collection System staff procedures for reporting SSOs and response and
notification procedures.
(ii) Overflow Emergency Response Plan (ERP)
OCSD has developed and implemented an overflow emergency response plan that
identifies measures to protect public health and the environment, and includes, at a
minimum, the following:
(A) Proper notification procedures so that the primary responders and regulatory
agencies are informed of all SSOs in a timely manner.
The OCSD SSO response flow chart illustrates the established procedures that are
followed when a problem is reported. The plan provides the following:
• Reporting of a problem from internal and external sources
• Actions taken during normal (6:00 a.m. to 4:30 p.m., Monday thru Thursday)
and after normal OCSD business hours
• Staff and/or primary standby mobilization by the duty Operations Supervisor
or designee.
(B) A program to ensure an appropriate response to all overflows.
As shown in the OCSD SSO response flow chart, OCSD staff responds to all reported
problems, including those SSOs that do not discharge to waters of the state. OCSD
has a formal process to evaluate the jurisdictional responsibility and the cause of the
problem. This also includes a process in the event the reported event cannot be
located in the field. Once located, the following sequence occurs as outlined in the flow
chart:
• Attempt containment, using spill containment procedures
• If the SSO is OCSD's responsibility, initiate the spill notification process
• Control the SSO and eliminate the problem
• Recovery and cleanup
• Field documentation
• If the SSO is not OCSD's responsibility, the notification process includes
notification of responsible party, site assistance when requested, and field
documentation of the event.
(C) Procedures to ensure prompt notification to appropriate regulatory agencies
and other potentially affected entities (e.g., health agencies, Regional Water
Boards, water suppliers, etc.) of all SSOs that potentially affect public health or
reach the waters of the State in accordance with the MRP. All SSOs shall be
reported in accordance with the MRP, the California Water Code, other State
Law, and other applicable Regional Water Board WDRs or NPDES permit
requirements. The SSMP should identify the officials who will receive immediate
notification.

As shown in the OCSD SSO response plan flow chart, when a problem is reported, the
Control Center dispatcher notifies OCSD staff in accordance with established
procedures. The chain of communication for reporting is then implemented beginning
with a possible spill notification, and communicating with those on the spill notification
distribution list. OCSD staff responds and investigates, while the notification of SSOs
procedure provides notification processes for the following:
• Events that occur during normal (6:00 a.m. to 4:30 p.m., Monday thru Thursday)
and after normal business
• Non-OCSD service area events
• Internal notification for support from the OCSD Environmental Compliance (EC)
division
• OCSD laboratory staff or other appropriate OCSD divisions
• Evaluation on case-by-case basis to initiate monitoring, reporting and additional
control and elimination procedures as necessary.
(D) Procedures to ensure that appropriate staff and contractor personnel are
aware of and follow the Emergency Response Plan and are appropriately
trained.
OCSD has an existing formal training program for OCSD staff that requires mandatory
safety training, technical skills training and supervisory/management skills training. The
program also uses California Water Environment Association (CWEA) certification and
on-the-job training (OJT) as part of this program. The current program is being
supplemented with a multiyear focused training and validation program.
OCSD has use of an on-site SSO simulator that allows crews to practice SSO
response, containment procedures, and estimate overflow volume using metered
discharges from a manhole and cover. Documented SOPS are being developed for this
purpose. Contract specifications for Capital Improvement Projects (CIP) require that
contractors develop their own SSOERPs.
(E) Procedures to address emergency operations, such as traffic and crowd
control and other necessary response activities.
OCSD has existing traffic and safety control procedures that comply with Caltrans and
CalOSHA requirements. These include:
• Adherence to Work Area Traffic Control Handbook (WATCH) procedures
• Use of confined space entry/rescue certified personnel as necessary
• Use of personal protective equipment
• Site security
• Use of law enforcement agencies as necessary for site-specific needs. Events
requiring law enforcement assistance are evaluated on a case-by-case basis.
• Contractors are used to supplement agency staff as necessary
(F)A program to ensure that all reasonable steps are taken to contain and
prevent the discharge of untreated and partially treated wastewater to waters
of the US and to minimize or correct any adverse impact on the environment
3 of
resulting from the SSOs, including such accelerated or additional monitoring
as may be necessary to determine the nature and impact of the discharge.
The OCSD SSO response flow chart has steps identified that are specific to:
• Containment
• Control and elimination of the SSO
• Cleanup
• Failure analysis and debriefing
Standard procedures and materials have been developed for the specific steps in the
flow chart, and are available in OCSD vehicles. Equipment to assist in the containment,
control and elimination, and cleanup is also available.
Events are evaluated on a case-by-case basis. The need for monitoring is determined
based on possible impact to recreational waters, and in coordination with RWQCB and
OCHCA staff. OCHCA or the RWQCB have responsibility for sampling. OCSD may
provide assistance with sampling if requested.
OCSD staff worked with the County of Orange to develop a plan for containing and
recovering SSOs to surface waters, storm drains and channels. This may include hiring
an on-call contractor to assist in recovering SSOs that have reached storm drains or
channels. OC Public Works now manages and executes the Countywide Area Spill
Control (CASC) Program.
The OCSD Control Center is staffed with dispatchers 24 hours a day, 7 days a week.
OCSD has an on-call list with a primary contact. If the primary contact cannot be
dispatched, an assigned secondary staff person is contacted and dispatched. On-call
staff is authorized to mobilize additional staff and equipment as needed. A response
time of one hour or less is an established goal and measured performance metric.
OCSD has adequate staff and equipment to respond to historic normal service
requests, including SSOs. If additional resources are needed for extraordinary events,
OCSD maintains a contact list of contractors and suppliers, and has standing blanket
purchase orders to mobilize the additional resources rapidly and specific to the event,
whether it is a gravity sewer or pump station problem.
OCSD contractors are provided the Master Spec 02999 Temporary Handling of Sewage
Flow. This document provides guidance and contains language on how to respond to
sewage spills at the project work site. The document requires contractors, as needed,
to develop a Spill Prevention, Control, and Countermeasure Plan, which includes spill
notification, response, containment, and reporting protocols in the event an SSO occurs.

Task: SANITARY SEWER OVERFLOW RESPONSE
SOP Number: 870-GEN-08 (Rev 01) Effective Date: 01/27/2009
STEPS IN PERFORMING THE TASK/PROCEDURE
1. Comply with Orange County Sanitation District General Safety aApE
Rules (May 2002; example adjacent).
2. Upon receipt of a call from the Control Center,the supervisor '--'mot=_ �-•—
will assign dispatch aresponse team(minimum 2-person crew).
e„ -
• If the SSO is reported after normal business hours, the ` =
Control Center will contact the standby persons to = ='==z�
respond.
�_ _>_
3. Prior to the start of work, conduct a tailgate safety meeting to
discuss safety precautions,review procedures, and assign
responsibilities to each person on the crew.
4. Response personnel are to select a vehicle appropriate for the spill location,typically a
Vactor Truck.
5. Prior to mobilizing to the spill, identify the spill location on the Trunk Sewer Atlas to
collect preliminary information. This information includes:
• OCSD lines in the vicinity
• OCSD line size(s)
• Distance between manholes
• Location of Diversion Structures
NOTE: The line size located on the map will help determine the resources needed to
respond to the spill.
6. Upon arrival at the spill location,the first responders typically perform multiple tasks
within a relatively short amount of time. These tasks are listed below and described in
further detail below and summarized in Attachment A: OCSD SSO Response
Flowchart.
A. Communication with Control Center. The field personnel we to maintain
communication with the Control Center to establish a timeline needed for reporting
purposes. The key information that needs to be communicated are: arrival time,
estimated spill volume,time spill containment was set,time the blockage was
relieved,and time the containment was removed.
B. Spill Verification. The field personnel are to determine whether the spill is a sewer
spill or other type of spill.

Task Procedure Analysis Worksheet REV 01
Task: SANITARY SEWER OVERFLOW RESPONSE
SOP Number: 870-GEN-08 (Rev 01) Effective Date: 01/27/2009
C. Communication with Supervisor. The field personnel are to maintain communication
with a supervisor during work hours. The supervisor assigned is typically the person
who dispatched the crew to the spill. Field personnel are to relay pertinent
information to the Supervisor who will assign additional resources, as needed.
• If the spill occurs after hours, communicate directly with the Control Center.
D. Spill Containment. The spill containment task involves the setup of traffic control
equipment, spill containment material placement, public safety measures, etc.
• Traffic Control. If the spill is located
in an area where traffic control is
needed, all traffic control setups should
be consistent with the "OCSD Traffic
Control Manual'and the "Work Area
Traffic Control Handbook
(W.A.T.C.HJ"
• Public Safety. If additional resources are needed to manage or control the
public safety, contact the Supervisor or Control Center and they will notify the
appropriate agencies.
• Spill Containment. Containment materials are to be set up in strategic
locations to control and contain the spilled wastewater. These materials
include: rubber mats, sand bags, sorbent materials(socks,pillows,booms),
soil, or any materials located near the spill that can aid in spill containment.
The containment materials - , i -
should be set up to block the
spill from entering (or
continuing to enter) storm -
drains or other waterways.
If possible, spills should be -'��
diverted to natural low areas
where the materials can
collect prior to removal.

E. Spill Source Determination.
Once spill containment is
properly placed and working
effectively, field personnel are
to determine the source of the
sewer spill (OCSD, City, or
private party) and relay that
information to the Supervisor.

G. Field Documentation. The field personnel are to document the spill area and all field
activities performed.
• Notes. At a minimum, the field notes should include arrival time, time spill
containment was set, time the blockage was relieved,departure time, and all
persons and equipment mobilized to the scene. In addition,document any
officials(law enforcement,health department,etc.)who are present. If any
official gives direct orders that stray from the OCSD spill response procedures,
document that person's information(name,badge number,phone number) and
notify the OCSD supervisor; if the spill occurs after hours, relay the pertinent
information to the Control Center.
• Sketch. The field sketch should document the path of the flow, the height of
the water coming from the manhole eyes,the location of the sewage, storm
drains,waterways, and the manhole or structure ID numbers.
• Photographs. Photographs (preferably digital) should be taken of the spill
area, spill containment measures, scene after cleanup, and any other
information deemed pertinent.
H. Blockage Location Determination. Field personnel are to determine the location of
the blockage. The blockage location is determined by opening manhole covers
downstream of the spill location to look for surcharge. Prior to opening the
manholes(OCSD or City),check for explosive or toxic gasses using a direct-
reading air monitoring device(Gas Tech)by inserting tubing into the pick-holes.
If explosive gases are present DO NOT LIFT OR REMOVE the cover.
Start by opening the first manhole
downstream of the spill. If surcharge is
observed, move to the next downstream --_ —
manhole. When no surcharge is observed in a
manhole, the blockage is located somewhere ,,,,w•'°'
between that manhole and the spill location. -'

8. Once the blockage location has been determined, set up the Vactor truck on the first
downstream manhole that was not surcharged.
9. Place one crew member on the downstream side of the Vactor truck with a rake or other
device designed to catch the blockage.
10. Personnel at the Vactor truck are to run the penetrating nozzle upstream to relieve the
blockage.

xosrquame since»
11. The crew member staged on the downstream side of the Vactor truck is to catch the
blockage with debris catching equipment(i.e.,rake). This minimizes the amount of
blockage material traveling through the line to minimize future blockages. Identify
blockage material to determine the cause of the obstruction and potential follow-up
activities necessary.
12. Once the blockage is cleared, document the time and relay the information to the Control
Center as soon as possible. This information is extremely important in the final
calculations used to determine the volume spilled.
• If a blockage can't be relieved within a reasonable amount of time, contact the
supervisor and/or Control Center to discuss response options(i.e.,additional staff
and equipment)or use of upstream diversion structures. It is important to contact
the Control Center prior to diversion structure implementation to verify that
potentially affected parties are notified.

13. Determine the further follow-up actions needed for the blockage area(i.e.,root cutting if
roots are collected on the rake, line cleaning if grease is observed, etc.). Follow-up
procedures can include line cleaning,root cutting, line repairs, and CCTV.
14. Assess the flow in the line to verify that the blockage has not migrated to a downstream
segment. Prior to opening the manholes (OCSD or City), check for explosive or
toxic gasses using a direct-reading air monitoring device(Gas Tech)by inserting
tubing into the pick-holes. If explosive gases are present DO NOT LIFT OR
REMOVE the cover. If conditions are acceptable,open several downstream manholes
and look for surcharge in downstream manholes. If no surcharge is present,the line
segment is determined to be clear.

SSO Volume Estimation
Accurate flow estimation is essential to determine the volume of a Sanitary Sewer Overflow
(SSO). An accurate estimate of an SSO is required for reporting to the California Integrated
Water Quality System(CIQWS) and to the local health care agency. The estimated volume of
an SSO is used to determine the category of the SSO and can also be used in the calculation of
penalties or fines from the State or Regional Water Quality Control Boards in California.
Additionally, accurate flow estimation is important to determine the extent of the cleanup and
its effectiveness.
Volume estimation is basically the flow rate (gallons per minute)times the amount of time(in
minutes) the flow has occurred. Each SSO tends to be unique requiring different strategies for
determining the volume of the SSO. Different methods can also be used for the same SSO
acting as a check to ensure the most accurate estimate. The method(s)utilized will be
determined by several factors including the type of SSO and the personnel responding. Some
SSO volumes, due to terrain,rainfall or other factors,can be very difficult for field staff to
determine and may require someone with additional expertise. There is no one method that
works for all types of SSOs. The following are methods that may be utilized for SSO volume
estimation. These methods are effective means of estimating a sewer spill volume during dry
weather but may not be effective during rain events.
During rain events, infiltration and/or inflow into the collection system and runoff in the
stormwater system, including the curb and gutter, can affect the SSO estimate. When
estimating an SSO during a rain event, the SSO estimate is to include only the wastewater that
left the collection system and not any waters that the wastewater comingled with after leaving
the system. The same is true for any wash down water; although contaminated, the water is not
considered part of the SSO estimate. Any water that infiltrated into the collection system
upstream of the SSO and subsequently became part of the SSO is included in the SSO volume
estimate.
Hddept\A&\Common\WD1GWpiJ1 Guide...revised 051514 3 of 29
Start Time
Determining the start time for an SSO is one of the most critical, yet can be one of the most
difficult, factors to determine. Depending upon the location and time of day, an SSO may
occur for some time before it is reported to the City or Agency or it may trickle for an extended
period of time before being noticed. What is known is that the SSO started some time before
the City or Agency was notified. It is common for SSOs to start and stop as flows in the
pipeline routinely rise and fall because most blockages do not entirely block the flow in the
pipe. Every effort should be utilized to determine the most accurate start time of each SSO.
These efforts may include:
• If possible, contact the person who reported the SSO to determine when they became
aware of the SSO.
• Make contact with residences or businesses in the area of the SSO to determine if there
were any witnesses that could help establish the start time.
• Conditions change during the SSO. This is particularly true in remote areas out of
public view. Initially, there may be an amount of toilet paper and solids around the
spill site. This will increase the longer the SSO continues. After a few days to a week,
these may form a light brown residue that may turn dark after a few weeks to a month.
Lacking direct evidence supporting a specific start time the operator should rely upon their
experience and system flow characteristics based upon observed conditions to establish a
reasonable estimated start time for the event. The agency's management staff should review
the estimate before being finalized. Methods used to establish the start time should be
documented.
Stop Time
The stop time is the time that wastewater stopped overflowing. For manhole covers in low
areas,this is noted by water flowing back into the manhole through the vent holes and should
be easy to determine by SSO response personnel. Cue should be taken to accurately record
the time that the SSO stopped.
Hddept\A&\Common\WD1GWpiJ1 Guide...revised 051514 4 of 29
Photographs
Take photographs of the spill event. Try to include objects of known size in the photographs to
give a perspective of the extent of the spill. Photographs should include the initial spill,
remediation efforts, clean up, and the spill area after the spill remediation has been completed.
Photographs should be maintained with the spill report information.
Flow Rate
The flow rate is the volume of flow per unit time that is escaping from the collection system.
SSOs do not always occur at a constant rate. This is because flows into the collection system
are not constant and rise and fall throughout the day. Additionally,most blockages are not full
blockages. Pressure buildup as the wastewater surcharges in the pipe can cause the blockage to
clear or partially clear,resulting in changes to the flow rate.
To make an SSO volume estimate as accurate as possible,the onsite City or Agency employee
should note the time and the amount of change of any significant differences in flow noticed
during the event. For example, if the employee determines the flow rate escaping from the
manhole is 100 gallons per minute when they arrive on scene but noticed that it has dropped to
50 gallons per minute five minutes later,their report should reflect that fact. The estimated
flow rate and the time period for that flow rate should be recorded. During any one SSO event
there could be multiple flow rates spread over the duration of the SSO.
Volume Estimation Methods
Visual or Eyeball Method
The volume of small spills can be estimated using an "eyeball estimate" To use this method,
imagine the amount of water that would spill from a bucket or a barrel. A full bucket may
contain 1,2 or 5 gallons and a barrel contains 55 gallons when full. If the spill is larger than 55
gallons,try to divide the standing water into barrels and then multiply by 55 gallons. This
method is useful for contained spills up to approximately 200 gallons. This method can be
useful on spills that occur on hard surfaces such as concrete or asphalt. Crews can be trained
Hdd,t\A.\Common\WDR\Spill Gui&...visW 051514 5 of 29
by estimating the volume of a measured amount of potable water spilled upon concrete and
asphalt surfaces.
Measured Volume
The volume of most small spills that have been contained can be estimated using this method.
The shape, dimensions, and the depth of the contained wastewater are needed. The shape and
dimensions are used to calculate the area of the spills and the depth is used to calculate the
volume.

Triangle: Area=base(feet)x height(feet)x 0.5
6. Multiply the area(square feet)times the depth(in feet)to obtain the volume in cubic

7. Multiply the volume in cubic feet by 7.48 to convert to gallons

Not all SSOs will conform to a specific shape. When this occurs, break up the area of the SSO
into various shapes or segments, then calculate the amount of wastewater spilled in each
segment,adding them together to arrive at the total spill volume.
Example:

divided into 4
geometric sections.
Determine the area of each of the geometric sections adding them all together to
determine the total area of the spill.

Counting Connections
Once the location of the blockage has been established,the amount of the SSO could be
estimated by counting the number of upstream connections. On the sewer atlas maps or GIS
system, locate the pipeline where the SSO occurred. Count all of the developed parcels that
are connected to the pipeline upstream of the blockage. The typical single family residential
parcel may discharge 8 to 10 gallons of wastewater per hour during active times of the day.
For a multi-family residential development such as an apartment or condo complex, count each
apartment as a single family residential unit. Use the higher flow number(10 gallons per hour)
during typical peak flow hours and the lower flow number(8 gallons per hour) during low flow
periods. Multiply the number of connections times the average flow (8 to 10 gallons per hour)
times the time period(duration) that the SSO occurred.
Example for an SSO occurring on a weekday at 8:00am:
Number of upstream connections 22
Estimated flow per parcel 10 gallons per hour
Duration of SSO event 45 minutes
Total spill estimation (22 x 10 x .75) 165 gallons
(22 connections x 10 gallons per hour x 45 minutes (.75 hour)= 165 gallons)
Data may be available in your drainage area from your capacity planners at your city or
agency. Consult with them on reasonable flow amounts or rates of flow.
Pick and Vent Holes in Manhole Covers
Small SSOs will occur where the wastewater escaping from the manhole is isolated to the pick
or vent holes in the cover. Larger SSOs may involve both the discharge from the pick and/or
vent holes and the gap between the manhole cover and manhole frame. To estimate an SSO
occurring from the manhole pick and vent holes,measure the height of the wastewater plume
exiting the holes. Find that height and hole diameter on the manhole pick or vent hole chart to
detern ine the flow rate escaping the pick/vent hole. Multiply the flow rate times the number
of holes that are discharging wastewater. Once the total volume(gpm)has been determined,
Hddept\A&\Common\WDRWpiJI Guide...revised 051514 8 of 29
multiply the gpm by the duration of the SSO in minutes. This will result in the total estimated
gallons of the SSO.
Height to be measured - 1
Example: Measured height of plume exiting pick/vent hole is 1 inch from a'/z-inch vent hole
and there are 4 vent holes. The total volume per minute would be .94 gpm per hole (from
attached chart) or 3.76 gpm total(.94 gpm x 4 holes) from the manhole cover. If the SSO
lasted one hour,the total wastewater lost would be 226 gallons(3.76 x 60=225.6).
Number of pick holes 4
Flow from each pick hole .94 gpm
Duration of SSO 60 minutes
Total SSO volume(.94 x 4 x 60=225.6) 226 gallons

Manhole Ring
Some manhole covers in use today typically only have one pick hole forcing most of the
wastewater to escape from the perimeter of the manhole cover during higher flow SSOs. To
estimate the volume in this example,measure the observed height of the wastewater plume
exiting the manhole cover. Find the height and manhole diameter on the Manhole with Cover
in Place to determine the flow rate escaping the manhole. The chart has two columns,one for
24-inch diameter covers and one for 36-inch diameter covers. Wastewater will also be
escaping from the pick hole and must be accounted for separately by following the instructions
for estimating an SSO from pick/vent hole. Multiply the flow rate times the number of holes
that are discharging. The total estimated rate(gpm)is determined by adding together the rate
being lost(gpm)from around the cover with the rate being lost(gpm) from the pick and/or
vent hole(s). Once the total rate (gpm)has been determined,multiply the gpm by the duration
of the SSO in minutes. This will result in the total estimated gallons of the SSO.
HEIGHT TOLUCEASURED
ter.
Example: The measured height of the plume exiting the ring of a 36-inch manhole is 1 inch.
The total volume per minute would be 13 gpm from around the ring of a 36-inch manhole
cover(from the attached chart). (Calculate the amount exiting the pick hole(s) and add to the
total being lost around the ring). If the SSO lasted one hour the total wastewater lost would be
780 gallons (13 x 60=780).
Estimated loss around ring(from chart) 13 gpm
Duration of SSO 60 minutes
Total SSO (without loss from pick hole) 780 gallons
(13 gal/min x 60 minutes=780 gallons plus amount lost from pick hotels))

The formula used to develop Table 1 measures the maximum height of the water coming out of the
maintenance manhole above the rim. The formula was taken from Hydraulics and Its Application by
A.H.Gibson(Constable&Co.Limited).
Partially Covered Manhole
Sometimes an SSO will occur that only lifts one side of the manhole cover. This is especially
true of manholes where the cover is on an incline with the cover lifting on the downward side
of the manhole. To estimate the volume of an SSO under these conditions, calculate the area
(in square feet)from where the wastewater is escaping and the velocity(in feet per second)that
the wastewater is normally traveling in the sewer at half the pipe depth. The velocity is
estimated from visual observation with 2 feet/second or less being a small velocity,4 to 5
feettsecond being a medium velocity, and 7 feet/second or higher being a large velocity.
Velocities in the sewer above 7 feet/second may be strong enough to blow the manhole cover
off. Higher velocities also tend to raise the manhole lid higher. Next,multiply by the duration
Hddept\he\Cuunuof WDR\Spill Guide...revised 051514 13 Of 29
(in seconds)that the SSO occurred. Finally,multiply by 7.48 to determine the volume of the
SSO in gallons. The formula is Volume (gallons)=Area(sq. ft.)x Velocity(ft/sec)x Time(in
seconds)x 7.48 (gal/cu. ft.).
HEIOMT TO OM MEASUREO
Example: The measured height of the plume exiting the side ring of a 24-inch manhole is 2
inches. Based upon the data provided in the Area Calculation Chart below, a 2-inch plume
from one side of a 24-inch manhole cover provides 0.524 square feet of area. The velocity of
the flow is estimated at 4 ft/see(visual observation)with the assumed duration of the flow
lasting for one hour. The total amount of the SSO is estimated at 56,441 gallons (.524 x 4 x 60
x 60 x 7.48 =56,441)

Open Manhole
In large events the force of the overflowing wastewater will have sufficient pressure and
volume to unseat the cover from the frame and move the manhole cover away from the
manhole. Typically,when the SSO rates reach approximately 7 cfs (approximately 3,000 gpm
or about 4.32 mgd), there is sufficient flow and pressure to blow off the manhole cover. To
estimate the volume of an SSO where the manhole cover has been removed, the average height
of the plume of wastewater exiting the manhole must be measured. This measurement is from
the pavement surface close to the manhole ring to the top of the plume. Take several
measurements in several locations around the ring and average the findings. If possible, and
being safe to protect yourself from the open manhole, find the average height of the plume for
the size of the manhole lid(24-inch or 36-inch diameter)on the Area Calculation Chart to
determine the rate of flow exiting the manhole. Multiply the flow rate expressed in gallons per
minute from the chart multiplied by the duration of the SSO in minutes to determine the total
volume of the SSO. A photo taken at a safe distance upon arrival may help you refine your
estimate.
/ HEIGHT TO BE MEASURED
Example: Determine the observed height of the plume at several locations around the ring of
the manhole and average the results. Determine the size of the manhole cover. If the average
height of the plume exiting an open 24-inch diameter manhole is 2 inches, find 2 inches on the
24-inch Manhole Cover Removed Chart. Based upon the data provided in the Manhole Cover
Removed Chart,the flow in gallons per minute would be 3,444 gpm. If the duration of the
flow lasted for one hour(60 minutes),the total amount of the SSO would be estimated at
206,640 gallons (3,444 x 60=206,640).

Pictorial Reference
Currently there are two picture charts being widely used to assist with estimating SSO
volumes. The older chart is the city of San Diego's Manhole Overflow Rate Chart with the
newer chart being the CWEA Southern Section Collection Systems Committee (SSCSQ
Manhole Overflow Gauge. Each chart is a pictorial depiction of how an overflowing manhole
appears at a given flow rate. The SSCSC Manhole Overflow Gauge has an additional picture
for each flow rate showing a wide angle view of the spill area. When using either of the
pictorial reference charts, select which picture most accurately represents the SSO being
estimated. Use the gpm of the associated picture multiplied times the duration of the SSO to
determine the total spill volume. Example: If the selected picture shows 300 gpm and the
duration of SSO is 55 minutes,the total estimated spill volume would be 16,500 gallons (300
gpm x 55 min).
Selected picture volume 300 gpm
Duration of SSO 55 minutes
Total estimated SSO 16,500 gallons
(300 gpm x 55 minutes= 16,500 gallons)
Note: Data was obtained at training facilities where potable water was metered and photos
were taken at various flow rates.
Training facilities also exist at the Orange County Sanitation District in Fountain Valley, CA.
As a reference point, an 8-inch diameter sewer flowing half full at a velocity of 2.5 ft/sec
would have a flow rate of about 192 gal/min. If fully blocked,the SSO rate would be 192
gpm. For a partial blockage,the SSO rate will be less.
Other agencies have developed above ground estimating tools such as frame and cover sets that
can be pressurized using potable water and simple flow meters.

Gutter Flow (Simplified Version)
Although the traditional Manning's Equation is used to calculate flows in open channels,this
simplified version can be used to measure SSOs that are flowing in open channels such as
ditches, curb and gutter, etc. and still achieve reasonable estimations. Two things need to be
determined to utilize this method of spill estimation,the cross sectional area of the channel and
the velocity of the flow in the channel. First, determine the cross sectional dimensions of the
channel (width and depth of flow) to determine the area of the flow. Then determine the
velocity of the flow in the channel. To determine the velocity,drop a small floating object
(ping pong ball, leaf, small piece of wood, etc.) into the flow and time how long it takes the
object to travel a measured distance. This should be practiced several times in a non-SSO
situation,and averaged to determine the flow velocity. The velocity of the flow multiplied by
the cross sectional area of the flow multiplied by the duration of the SSO will result in the
approximate volume of the SSO.

Q=VxA
Flow (gal/min)=Velocity (ft/sec)x Area(ft?)x 7.48 gal/cu ft x 60 sec/min
Example: If the cross section triangular area of the spill is calculated at.5 sq.ft. with the
velocity measured at .25 ft.per second, the flow would be .125 cubic feet per second. Multiply
times 449 (one cubic foot per second equals 449 gallons per minute) to determine the gallons
per minute (56 gpm). If the SSO lasted for 35 minutes the total estimated spill volume would
be 1,964 gallons.

estimated gallons spilled)
Gutters on steep hillsides will flow at higher velocities. Practice your estimating on flatter
areas and steeper areas of your service area.
Bucket Method
This method can be used for small spills due to partial blockages where the entire flow stream
could be captured in a bucket. Estimate how many minutes it takes to fill the bucket. Dividing
the volume of the bucket(in gallons)by the elapsed time to fill the bucket(in minutes). This
provides the flow rate in gallons per minute (gpm). Once the gpm has been established,
multiply the gpm by the total time duration in minutes of the SSO until it stopped to determine
the total estimated volume of the SSO.
Example: If it takes 30 seconds (.5 minutes)to fill a 5 gallon bucket and the total spill duration
was 20 minutes,the total spill volume would be 200 gallons. (5gal/.5 min= 10 gpm x 20 min
=200 gal).
Time to fill a 5 gallon bucket 30 seconds (.5 minute)
Duration of SSO 20 minutes
Estimated spill volume 200 gallons
(5 gallons every 30 seconds equals 10 gallons per minute x 20 minutes=200 gallons)
You can practice visual estimating by filling a bucket of known volume for a measured time
from a garden hose.
HAdept\fsa\CommonoVD1GapiJ1 Guide...revised 051514 22 of 29
Pipe Size
To calculate an SSO based upon pipe size requires the diameter of the pipe, the depth of flow
in the pipe downstream of the blockage during and after the blockage, and the flow velocity in
the pipe. This method calculates the amount of flow in the pipe at the same time of the day
during the blockage compared to the amount of flow normally in the pipe to determine how
much flow had been lost over time.
To use this method, measure the flow depth at the nearest manhole downstream from the
blockage. Record the depth reading. Once the blockage has been cleared and the flow
stabilized, measure the flow depth at the same manhole as before and record the reading. The
attached chart can be used on various size pipelines where the velocity is 2.0 feet per second.
Pipelines of other rates will have to be calculated.
To use the attached chart, find the depth of the flow during the blockage in column 1. Follow
the row across to the diameter of the pipe where the blockage has occurred. The number listed
will be the flow rate in gallons per minute for pipelines with a velocity of 2 feet per second.
Next find the flow depth after the blockage has been removed and the flow stabilized. Move
across the chart to the proper pipe size and record the flow rate for a free flowing pipeline.
Subtract the flow rate from the blocked pipe from the flow rate of the free flowing pipe. The
remainder will be the flow rate lost. Multiply the flow rate lost times the duration of the SSO
to determine the total flow volume lost. Example: If the flow depth during the blockage of a
10-inch pipe was 1 inch,the flow rate would 25 gpm. After the blockage was cleared and the
flow stabilized, the flow depth was now 5 inches then the flow rate would be 240 gpm. To
deterrame the amount lost, subtract the gpm(pipe blocked) from the gpm(pipe cleared) (240
gpm—25 gpm=215gpm) leaving the flow rate of the SSO. Multiply the remaining flow rate
multiplied by the duration of the SSO in minutes to estimate the total volume of the SSO.

Note: The above chart is only for pipelines of the diameters shown and flowing at a velocity of

Metered Flow
Estimates of the amount of wastewater spilled from a continuously metered system can be
achieved utilizing upstream and downstream flow meters located close to the point where the
wastewater escaped. Flow meters may be located at strategic locations throughout the
wastewater collection system or at the intake or discharge of wastewater pump or lift stations.
Flow metering usually occurs on pressure systems. If a spill is suspected on a metered
upstream wastewater line,check the flow meter readings for abnormalities and note the time
they start. Also check the flow meter readings at the downstream flow meter. If the
downstream readings are lower than usual,the difference may be the amount of wastewater
being lost to a spill. Abnormal pumping cycles for pump or lift stations located downstream
from the spill can also be used to estimate the volume of a spill. Portable flow meters could
also be installed in gravity sewers after a SSO event to help verify average flows at various
times of the day when full or partial blockages may have occurred. You should also perform
HAdept\AvCommoe\WDR\Spill Guide....vvW 051514 24 Of 29
this on the same day of the week that the SSO occurred. This is also a good way to understand
how flows will change during the day in various parts of your system.
Rain Events
Previous examples of methods throughout the document were all in dry weather situations.
Rain events cause substantial difficulties for SSO responders in establishing an accurate
estimate of an SSO. Infiltration into the sewer system will increase, sometimes dramatically,
the system flow including the amount of the SSO. When estimating the SSO amount during a
rain event,the estimate is to include only the amount of wastewater that left the collection
system(this includes any clear water inflow and/or infiltration(I&I)that entered the collection
system upstream of the SSO) and not any waters that the wastewater comingled with after
leaving the system. Although the comingled waters are considered contaminated by the SSO
and may be involved in the cleanup,they should not be considered in the estimate of the
volume of sewage spilled for the event. Consult with your city or agency management or your
site-specific procedures to be used during wet weather SSOs.
Saturated Soils
Spills that have occurred on or migrated to grassy or dirt areas can be estimated if the area is
dry and is not regularly irrigated like a field or dirt puking lot. This method is effective only
during dry weather and not during or after a rain event. To estimate how much wastewater has
been lost to the soil, first determine how many cubic feet of soil has been wetted. First
determine the size of the area where the spill occurred. This is done in the same manner as for
spills that occurred on hard surfaces and as discussed in the Measured Volume Method. Next
determine how deep the soil has been saturated. To determine the depth of the soil saturation,
dig several test holes with a round point shovel until dry soil is reached. Measure the depth of
each hole and determine the average depth of the saturated soil. Multiply the area of the spill
(in square feet)times the average depth of the soil saturation to determine the amount(in cubic
feet) of saturated soil. Different types of soils will retain moisture in different amounts. Water
will penetrate sandy soils quicker than clay soils and clay soils we capable of holding more
moisture than sandy soils. Use an average of 18%moisture content when estimating the
amount of wastewater that has saturated the soil.
Hddept\fsa\Common\WD1GWpiJ1 Guide...revised 051514 25 of 29
Example: If the spill was contained in a dry dirt or grassy area of 10 feet by 20 feet, the area of
the spill would be 200 square feet if it was a perfect rectangle(assumed). If the wastewater
penetrated the soil to an average depth of 3 inches, the total amount of saturated soil would be
50 cubic feet(10 x 20 x .25 = 50 cf). To determine the amount of wastewater suspended in the
wetted soil, multiply the 50 cubic feet times 7.48 gallons per cubic foot(50 cf x 7.48 gal/cf=
374 gallons). Next multiply the gallons times the average amount of moisture the soil can hold
(use 18% as a rough estimate or calculate the soil moisture)to determine the actual estimated
amount of wastewater that has saturated the soil(374 gal x .18=67.3 gallons of wastewater
contained in the soil for the area of the spill). Add the amount of wastewater estimated to be
contained in the soil with the amount of surface wastewater that was removed to achieve an
estimated total amount of the wastewater spill.
Simple method to calculate soil moisture content:
Equipment needed: One coffee filter; a funnel; a graduated measuring cup; ajar or bottle.
Place the coffee filter into the funnel. Place the funnel into the mouth of the jar or bottle.
Place one cup of clean dry soil from the spill site onto the coffee filter. Pour one cup (8
ounces) of water onto the soil and allow the water to drain into the jar. Once the water has
stopped dripping from the funnel,remove the funnel and measure the amount of water in the
jar. The difference between the amount of water in the jar and the 8 ounces originally poured
over the soil is the amount of moisture the soil retained.
Example: If six and one half ounces (6.5)remained in the jar,one and one half ounce (1.5) or
18.75%remained in the soil. The soil moisture content would be 18.75%.
Combo Truck or Vacuum Truck Recovery
When the spill is contained to a specific area and recovered by a combo or vacuum truck,the
amount recovered can be used in calculating the amount of the original spill. If the spill is
contained on a hard surface, estimate the total spill volume by what was captured by the combo
or vacuum truck plus the amount that could not be captured. To estimate the amount not
captured by the combo or vacuum truck,use the Measured Volume Method. For wet spots on
concrete,use a depth of 0.0013 ft. or 1/64 inch. For wet stains on asphalt,use a depth of
HAde,d\fsa\Common\WDR\Spill Guide...revised 051514 26 of 29
0.0026 ft. or 1/32 inch. If the spill is contained on soil,use the Saturated Soils Method to
determine how much of the spill soaked into the soil and add to the amount captured by the
combo or vacuum truck.

Auditing spreadsheet. Closes task in the audit findings spreadsheet. If the task
owner does not accept a finding, post reasons in audit findings spreadsheet and
closes task in EAP Share Point site. For the WDR audit: Once a reminder is
received by the task owner via ECAP, task owner will be accountable to respond to
reminder by clicking "complete" and date of completion. If not complete, document
status. Note: item will remain red in ECAP dashboard until complete.
H. Division Manager: Follows up with their staff who has been designated a task
owner, to assure he/she has resolved a finding. The responsible manager may ask
for clarification, resolve the issue immediately, or propose a schedule for resolution.
I. Purchasing: Finalize the SOW and RFB or RFP. Sends out the RFB or RFP to
appropriate contractors, maintains list of contractors, checks references, and checks
for appropriate certifications. Procures the third-party auditor/CONTRACTOR.
J. Legal: Legal review of audit documents or findings will only occur under exceptional
circumstances on an "as needed" basis.

ORANGE COUNTY SANITATION DISTRICT
Memorandum
DATE: June 30, 2016
SUBJECT: Closing Out the 2015 Audit of OCSD's Sewer System Management Plan
On July 31, 2015, Orange County Sanitation District(OCSD) received the audit findings from an
independent auditing firm, RMC, of the Sewer System Management Plan (SSMP). The audit
reviewed the period between January 1, 2013 and December 31, 2014 and found OCSD to
generally be in compliance with all Provisions of the WDR. The table below summarizes the
findings:
Non- om liance 1 Major Deficiency
Non_
CConformance 1 Ma'or Deficient
Non-Conformance 15 Minor Deficiencies
Opportunities 15
All non-compliance and non-conformance findings have been corrected or adopted. Several
"opportunities" and best practice recommendations were suggested. Staff will review these items
during the first half of the 2016/17 fiscal year. The following section summarizes OCSD's response
and action for each compliance and deficiency finding. For additional information on the referenced
regulatory section and corrective action completion date, a more detailed spreadsheet is available.
Non-Compliance
1. The SSMP was last certified in March 2012. The amended Monitoring and Reporting Program
(Order No. WQ 2013-0058-EXEC) requires documentation of SSMP updates. Records are not
attached to the SSMP documenting all changes made to the SSMP since its last certification
indicating when subsections were changed or updated and who authorized the change or
update.
Created log of changes to the SSMP that have occurred since the amended Monitoring and
Reporting Program went into effect in 2013 for Volumes I and Il. This log will be incorporated as
part of the cover page of each section, appendices, and/or chapter as appropriate.
Non Conformance— Maior Deficiency
1. In October 2014, the MS Access CCTV database exceeded the size limit and would not accept
any new records. The District is in the process of creating a Request for Proposals to purchase
an off-the-shelf CCTV software to serve as the future repository of CCTV inspection data. In the
meantime, CCTV data collected is being summarized for each inspection and loaded into a
spreadsheet. According to staff, almost all CCTV data collected is coded using PACP
standards. A quick review of the MS Access CCTV database tables indicates the table
structure and database format is not currently in PACP database format. OCSD will need to
transform that data into a format that can be migrated into the future CCTV repository database.
OCSD is purchasing a CCTV software package. Procurement is scheduled to be completed by
September 19, 2016.

Non Conformance - Minor Deficiencies
1. The SSMP Organizational Chart is missing three OCSD staff responsible for key elements of
OCSD's SSMP Program.
Updated the SSMP Organizational Chart to include OCSD staff responsible for key elements of
the SSMP Program.
2. CIWQS lists four OCSD staff an "Onsite Manager'also referred to as Legally Responsible
Officials (LRO). Update the SSMP, as appropriate; to identify who in the organization is
designated as a Legally Responsible Official in the CIWQS database.
The SSMP Organizational Chart and Organizational Narrative were updated to reflect the LROs
in CIWQS that can certify SSOs.
3. Several of the title descriptions on staff identified in the SSMP Program Organizational Chart
are dissimilar from the title descriptions in the Organizational Narrative creating confusion when
linking the two documents together. Similarly, the role designations on the SSMP Program
Organizational Chart do not always align with the SSMP Responsibility on the Organizational
Narrative.
Consistency between title descriptions in the SSMP Organizational Chart and Organizational
Narrative were addressed.
4. An additional position (i.e., Engineering Supervisor, Collection Facilities Division or designee of
the LRO) is included in the Appendix C -Organizational Narrative that is not included in the
SSMP Program Organizational Chart. This position is the WDR Subject Matter Expert as
defined in the District's Environmental Auditing Procedure TS-ECRA-SOP-011 included as
Appendix X1 of the SSMP and is responsible for managing the WDR/SSMP audit.
The Organizational Narrative and Organizational Chart were updated with positions responsible
for key elements of the SSMP Program.
5. The Organizational Narrative incorrectly identifies the Principal Environmental Specialist—
Management Services Team as responsible for the SSMP audit, yet this position is only
responsible for updating the status of the audit in ECAP. The District should update the
Organization Narrative and SSMP Program Organizational Chart to reflect these
responsibilities.
The Organizational Narrative and SSMP Program Organizational Chart were updated with
positions responsible.
6. Update Appendix P2 and Appendix P3 to reflect changes in monitoring and reporting
requirements amended on July 30, 2013.
Appendix P2 and Appendix P3 were updated on March 23, 2016 and were posted to the OCSD
SSMP documents external web page.
7. The OCSD website posts a Sewer Spill Estimation Guide that contains a more comprehensive
set of spill volume estimation methods along with a more detailed narrative description for how
to utilize these methods.
Updated Appendix R with the Sewer Spill Estimation Guide dated May 15, 2014.
Page 3 of 6
June 30, 2016
8. The 870-GEN SSO response procedures are referenced but not included in the SSMP.
Added the 870-GEN SSO to Volume ll, Appendix Q2.
9. The SSMP Chapter 7 does not reference notification procedures and response protocols for
sewer overflows caused by contractors working for the District. The District requires contractors
to develop a Spill Prevention and Countermeasure Control Plan (SPCC Plan), which is not
mentioned in the SSMP.
The SSMP has been updated. The OCSD Master Specification for Temporary Handling of
Sewage constrains language on how to respond to sewage spills in the Collections System.
Contractors are made aware of this language during meetings and are provided a copy of the
document.
10. SSMP describes the District's periodic master planning process, but does not describe the
process used by District staff to review major development proposals, apply the model as
needed to evaluate impact on hydraulic capacity, and update the model and its flows as new
information becomes available. Describe the District's ongoing modeling and capacity analysis
process in the next update of the SSMP.
OCSD will describe the ongoing modeling and capacity analysis process in the next update of
the SSMP.
11. References and design criteria information provided in the SSMP are not current. Update the
narrative and dates of reference documents for documents that have been revised.
OCSD will update the Design Criteria narrative provided in the SSMP in the next update of the
SSMP.
12. Based on the work performed for the 2009 Facilities Plan, some of the capacity projects
recommended in 2006 have been eliminated or deferred indefinitely on the basis of revisions to
flow projections or corrections/changes to the modeled network. However, some projects that
were determined in 2006 to present a likelihood of overflow under current development
conditions during a 10-year wet weather event have been deferred indefinitely, even though
subsequent modeling analysis has confirmed the original hydraulic deficiency. Although the
2009 Facilities Master Plan calls for those potential deficiencies to be monitored, there is no
documentation that any monitoring is being performed.
OCSD's Engineering Department is starting a master plan update that includes a large
monitoring program. The estimated start is in November 2016 through April 2018. Once this
effort has been completed and the data used to calibrate the hydraulic model to present day
flows, OCSD staff will consider an ongoing flow monitoring program. Type and placement of
monitors will depend on numerous factors, including value of the data, on-going construction
efforts, and operations and maintenance concerns.
13. SSMP and referenced documents such as the 2006 Strategic Plan Update, the 2009 Facilities
Plan, and Fiscal Year Budgets describe capital improvement projects for capacity enhancement.
Some of the identified projects have been completed and others deferred for a variety of
reasons. It is not easy to determine the status of each project because the information is
contained in various documents. Update table in Appendix M.
OCSD will update Appendix M, as appropriate.

June 30, 2016
14.The Audit Closeout Memo in Appendix Y was not updated after the 2013 WDR Audit. It is not
clear whether or how the audit findings from the previous audit were addressed. Update the
Audit Closeout Memo in Appendix Y to reflect the decisions and changes resulting from this
2015 WDR Audit. If the District chooses not to update the Audit Closeout Memo then the
District should consider updating the SSMP to remove the previous Audit Closeout Memo.
Updated the Audit Closeout Memo in Appendix Y to reflect the decisions and changes resulting
from the 2013 WDR Audit. Appendix Y will be updated with the decisions and changes resulting
from this 2015 WDR Audit.
The following section includes the 15 "Other Findings and Opportunities" not linked directly to
issues of compliance or conformance with the WDR.
1. Section 4.1 (c) of the SSMP discusses access for maintenance, inspection, or repairs for
portions of the lateral owned by OCSD. This section misses an opportunity to clearly state that
the District does not own and is not responsible for maintenance of the laterals connecting
private buildings to local sewers and therefore does not require access for maintenance,
inspection, or repairs of those laterals.
Legal counsel advised against addressing OCSD's lateral ownership in the SSMP for the
following reasons: 1) OCSD is a REGIONAL service provider, 2) OCSD is only a few months
away from divesting themselves of the vast majority of local sewers, 3) OCSD does not permit
direct lateral connections. Counsel states that it is a moot point to discuss ownership or lack
thereof in the SSMP.
2. Internal Stakeholder Meetings did not occur after the last audit. In the past, these meetings
served to support increased accountability for addressing WDR audit deficiencies and updates
to the SSMP.
Management will review recommendation and decide if this needs to be completed. This is not
a compliance requirement.
3. Over the past four years, OCSD has collected multiple data points for every asset in the local
sewer system.
• Four or more recent completed cleaning work orders with maintenance feedback
indicating type and severity of material found during cleaning.
• One CCTV inspection focused on condition assessment and potentially a second
inspection for cleaning quality control.
Management will review recommendation and decide if this needs to be completed. This is not
a compliance requirement.
4. During interviews staff indicated that trouble spot pipe schedules are regularly added, removed,
or modified as conditions warrant. For example, if a trouble spot pipe routinely comes back dirty
(based on contractor input or data), staff may consider cleaning it more often. Conversely, if the
pipe routinely comes back clean, staff will consider cleaning it less often.
Management will review recommendation and decide if this needs to be completed. This is not
a compliance requirement.
Page 5 of 6
June 30, 2016
5. Some of OCSD's internal goals have changed and are now more aggressive than those
documented in the SSMP. For example, OCSD's pipe inspection goal has changed from 7
years to 5 years and goals for manhole inspections are now set at 2 years.
Management will review recommendation and decide if this needs to be completed. This is not
a compliance requirement.
6. OCSD does not currently have a means to continuously update collection system risk as new
CCTV data is collected. This has evolved from being a best management practice to becoming
a standard industry practice. For example, NASSCO recently incorporated a risk assessment
methodology into the PACP standard. Also, off-the-shelf software with risk assessment
functionality is readily available in the wastewater industry marketplace.
Management will review recommendation and decide if this needs to be completed. This is not
a compliance requirement.
7. OCSD currently evaluates the maintenance and renewal needs of sewer pipelines on a case-
by-case basis.
Management will review recommendation and decide if this needs to be completed. This is not
a compliance requirement.
8. The District has utilized an assumption for asset deterioration to generate long-term
refurbishment and replacement cost projections. These projections are the basis for future
refurbishment and replacement funding for capital investment.
Management will review recommendation and decide if this needs to be completed. This is not
a compliance requirement.
9. OCSD has collected CCTV inspection data for almost all collection system gravity mainline
assets.
Management will review recommendation and decide if this needs to be completed. This is not
a compliance requirement.
10.The District is considering changing how specifications are assigned to design staff to improve
the update process. The process will enable staff to send comments on specifications to both
custodian and owner.
Management will review recommendation and decide if this needs to be completed. This is not
a compliance requirement.
11. Contractors are required to perform a quality assurance/quality control inspection of pipelines
after construction work is completed. In the past, the District would then perform a baseline
CCTV inspection. On some projects, the District is having the contractor perform the baseline
inspection. According to staff, OCSD's specification for the contractor (Spec 2730)does not
require a PACP inspection.
Management will review recommendation and decide if this needs to be completed. This is not
a compliance requirement.
Page 6 of 6
June 30, 2016
12. It is difficult to determine which SSOs reported to CIWQS were related to the local system
versus the regional system. It appears this information may be determined from the City field,
yet this is not clear.
Management will review recommendation and decide if this needs to be completed. This is not
a compliance requirement.
13.The District has invested significant funds to assist member agencies with their 1/1 reduction
efforts, but does not monitor the effectiveness of those efforts or attempt to quantify trends in 1/1
over time. It is important to the District that peak 1/1 be controlled by the member agencies.
Significant increases in peak 1/1 could result in additional hydraulic deficiencies that have not yet
been identified in the District's trunk sewers, as well as in the District's treatment plants and
ocean outfalls.
OCSD will partially comply;An 1/1 assessment will be completed as part of the Collection
Capacity Evaluation Study(start date October 2016);however, the potential date for completion
of this task is unknown at this time. If Orange County experiences a good rainfall event during
the 2016- 2017 wet weather season then this analysis will be completed after April of next year.
If drought conditions persist, then the analysis will hopefully be completed following the wet
weather season of 2017-2018. At this time, OCSD does not intend to formally document W
improvement efforts by member agencies.
14.Appendix 11 of the SSMP entitled Preventative Maintenance Program, specifies collection
system maintenance output goals. These goals are summarized in Table 8. Staff indicated
verbally that these commitments are being achieved, yet at the time of the audit data was not
readily available to validate this.
Management will review recommendation and decide if this needs to be completed. This is not
a compliance requirement.
15. ECAP is sending notifications to staff requesting review and update of SSMP sections. It is not
clear who the administrator is for the WDR in ECAP and whether these notifications are staying
updated.
Management will review and decide if this needs to be completed. This is not a compliance
requirement.
