Orange County Sanitation District FROM: James D. Ruth, General Manager Originator: Jim Herberg, Assistant General Manager CIP Project Manager: Victoria Pilko
SUBJECT: NEWPORT FORCE MAIN REHABILITATION, PROJECT NO. 5-60
GENERAL MANAGER'S RECOMMENDATION
A. Approve a Professional Design Services Agreement with Brown & Caldwell for
engineering design services for Newport Force Main Rehabilitation, Project
No. 5-60, for an amount not to exceed $1,944,364; and, B. Approve a contingency of $388,873 (20%).
SUMMARY
The purpose of this project is to rehabilitate the Newport Force Main system located on Pacific Coast Highway in Newport Beach between Bitter Point Pump Station and Dover
Drive.
The Professional Design Services Agreement (PDSA) includes professional engineering services to prepare a Preliminary Design Report, Final Design, and construction bid documents.
In July 2010, staff requested authorization to negotiate with Malcolm Pirnie (Arcadis
U.S.) for this work as a continuation of the assessment being performed by them. Subsequently, staff concluded that developing a new Request for Proposal (RFP) based on the revised Scope of Work is prudent to assure selection of the best design
consultant team, and the best approach considering the magnitude and critical nature of
the proposed work.
An RFP was sent to seven firms and three proposals were received and evaluated by staff. Based on the results of the evaluation and negotiations, staff recommends
awarding a PDSA to Brown & Caldwell as the most qualified consultant for a total
amount not to exceed $1,944,364 which was determined to be fair and reasonable for
the Scope of Work. PRIOR COMMITTEE/BOARD ACTIONS
None.

ADDITIONAL INFORMATION
The evaluation and selection process of the recommended consultant is based on
procedures pursuant to California Government Code requiring the Orange County
Sanitation District (Sanitation District) to select “the best qualified firm” for architectural and engineering services and to negotiate a “fair and reasonable” fee with that firm for those services.
An RFP which outlined consultant qualifications criteria required for this project to
perform the Scope of Work was sent to seven engineering firms and three proposals were received. A panel consisting of five voting members and three advisory members of the Sanitation District’s staff reviewed and ranked each of the proposals in
accordance with the evaluation process set forth in the Sanitation District Resolution
No. OCSD 07-04, Section 5.07. The proposals were evaluated according to the
following six criteria: (1) understanding of the Scope of Work, (2) technical approach, (3) management approach, (4) staff qualifications, (5) related project experience, and (6) schedule. Price was not included in the RFP for evaluation purposes as required by
State law.
Once initial ranking was established, staff also conducted interviews with each of the firms in order to meet the proposed key team members and further evaluate the firm’s proposal. Pursuant to the results of the interview, staff determined Brown & Caldwell
was the top-ranked team which met the qualification requirements in the RFP, as shown
in Table 1.
All proposals were accompanied by a sealed fee proposal estimate. The fee proposal estimates were not opened until the proposals were evaluated and a top-ranked firm
was identified.

Page 3 of 3
Staff conducted negotiations with Brown & Caldwell to clarify the requirements of the Scope of Work and to establish the final negotiated fee. The fee proposal was
evaluated as it relates to the negotiated Scope of Work and the required level of effort to
complete the project in accordance with the process as set forth in OCSD Resolution
07-04. Elements reviewed include total labor hours and labor-hour distribution by task as related to the work items, labor overhead rates, and profit calculations. These elements are compared to budgeted amounts, RFP requirements, industry standards,
historical data, and Sanitation District guidelines.
The proposed fee is $657,920 lower than the second-ranked proposer. Compared to the third-ranked and lowest cost proposal submitted by Arcadis U.S., Brown and Caldwell’s proposal provides significant additional benefits. This is an inherently difficult
project due to the type of work, permitting requirements, traffic restrictions and impacts
to residents and businesses. Brown and Caldwell’s proposal includes more elements to
reduce this risk including increased utility investigation, traffic control, a more conservative approach to temporary flow handling, and significantly more drawings to support this effort (roughly 45% more). Based on experience working on these force
mains and the recent Rocky Point Pump Station project, staff believes the approach
exhibited in the negotiated proposal will significantly reduce potential change orders,
delays and community impacts. Based on the negotiated proposal, staff determined the final cost proposal to be fair and
reasonable for the Scope of Work and recommends awarding the design contract to
Brown & Caldwell for an amount not to exceed $1,944,364.

SUBJECT: DIGESTER FERRIC CHLORIDE SYSTEM REHABILITATION, PROJECT NO. P2-105
GENERAL MANAGER'S RECOMMENDATION
A. Approve a budget increase of $784,500 for Digester Ferric Chloride System Rehabilitation, Project No. P2-105, for a total budget amount of $3,689,500; and,
B. Authorize the General Manager to negotiate a Professional Construction Services
Agreement with AECOM for engineering support services during construction of Digester Ferric Chloride System Rehabilitation, Project No. P2-105.
SUMMARY
Digester Ferric Chloride System Rehabilitation, Project No. P2-105, will replace the existing ferric chloride station and associated pipelines at Plant No. 2. The project also includes upgrades to the instrumentation and control systems that are currently
operated manually. AECOM is providing engineering design services for this project.
The construction estimate at the conceptual phase of this project was $1,400,000. During the detailed design of this project, it was observed that the original construction estimate was low for some items in the proposed Scope of Work. Also, several design
elements were added to improve safety and operability of the facility including additional
piping, paving, guard posts, and a new canopy for the new pumps and control panels.
The current revised construction estimate is $2,000,000. Staff requests an additional $784,500 in budget amendment to account for the increase in construction cost estimate, engineering support services during construction, and project contingency
costs.
AECOM has satisfactorily furnished engineering services for the design of this project and is in the best position to provide construction support services. The final design has been submitted and the contract documents are being prepared for the bid phase for
the project. Staff proposes AECOM to provide engineering services for the construction
of this project.
The services during construction will include reviewing equipment submittals, answering Contractor requests for information, reviewing plan changes, preparing as-built
drawings, and engineering support during commissioning and closeout of the project.

SUBJECT: PLANT 2 DIGESTER “O” LINER REPAIR
PROJECT NO. FR-2010-455BD
GENERAL MANAGER'S RECOMMENDATION
Approve a contingency increase of $395,000 to the Facilities Repair contract with J.R. Filanc Construction Company (Filanc), for Plant 2 Digester “O” Liner Repair Project,
Specification No. FR-2010-455BD, for a total contingency amount of $472,700 (89%).
SUMMARY
This repair project is rehabilitating Digester “O”. Digester “O” was placed into operation
in 1972 and is almost forty (40) years old. Repair work consists of replacing the existing
poly vinyl chloride (PVC) plastic liner which was installed in 1999 as part of the P2-39
Digester Rehabilitation Project, sand-blasting and removing damaged concrete, applying a new, spray-on, polyurethane plastic liner, and making repairs to the
associated process piping. The project was competitively bid per plans and
specifications and awarded to Filanc in July 2010. Plans and specifications were based
on a limited amount of previous rehabs OCSD has performed.
The contractor started the repair work and discovered and informed OCSD staff that the
existing reinforced concrete dome interior was in worse condition due to acid attack
than anticipated and indicated on the project drawings and specifications. The
contractor has removed the contract specified amount (up to one inch) of unsound
concrete in areas located inside the reinforced concrete dome, yet continues to find unsound concrete deeper than the contract specified amount. This material must be
removed prior to the coating application, or the new lining system could fail prematurely
by not adhering to a clean and sound surface. Too thin of a reinforced concrete dome
cross section would be structurally unreliable.
The contract drawing, specifications, and required work was based on a limited amount
of condition assessment work. Additional assessment work could not be conducted on
the dome because the damaged liner was in place. Since a contractor was required to
remove the damaged liner, staff collaborated and decided to move forward with the limited information as best available at the time. Unfortunately when the liner was
removed, additional damage was discovered during the sand-blasting process.
Page 2 of 5
The additional surface preparation required to remove the significantly damaged
concrete has resulted in additional work elements that are needed to provide a proper
repair to ensure structural strength as well as a proper surface to bond the new liner.
The latest requirements to properly manage the new risks include removal of protruding carbon steel rebar support “chairs” used when the dome was originally cast in place, installing the manufacturer’s recommended “pre-coat” material and a corrosive
inhibitor, and then installing a new cement mortar base for the final “spray applied”
corrosion resistant coating.
The contractor has completed between half and three-quarters of the specified work. The original contingency of $77,700 (15%) is inadequate to cover the cost for the
unknown repair conditions identified and continue the work. An additional contingency
of $395,000 for a new total contingency of $472,700 (89%) is required to complete the
project work. Staff recommends this approach as it is still more cost effective than demolishing the entire dome and replacing with new. Operations staff also needs the facility back in service as soon as possible as it cannot take additional digesters out of
service that are in need of cleaning and repairs similar to this one. Lessons learned
after this work is completed will be compiled and evaluated and discussed by a District
wide team including experienced consultants if needed. Recommended improvements to possible inspection methods bid specifications, plans, and schedules will be used on future repair projects in digesters needing similar work. A briefing can also be
presented to the Operations Committee at that time.
PRIOR COMMITTEE/BOARD ACTIONS July 2010 – The Board rejected the low bid given to Gamma (non- compliance of the
contract requirements) in an amount not to exceed $496,300 for Plant 2 Digester “O”
Liner Repair, Specification No. FR-2010-455BD. The Board approved a purchase order
agreement with Filanc for a total amount not to exceed $518,000; and approved a contingency of $77,700 (15%).
June 2010 - The Board approved a purchase order agreement with Gamma Builders,
Inc., for Plant 2 Digester “O” Repair, Specification No. FR-2010-455BD, for a total
amount not to exceed $496,300; and approved a contingency of $74,445 (15%).
ADDITIONAL INFORMATION
During the design phase, OCSD staff conducted a routine condition assessment of the
interior portion of the Digester dome. There were three (3) large flaps of protective PVC
sheet material that were torn in the lower part of the existing lining between the ceiling
and the walls of the Digester dome. Other than the three (3) tears, the lining system on the dome ceiling was mostly intact and based on past experience was expected to have sound concrete behind it. This liner while intact and well bonded prevented a detailed
assessment of the reinforced concrete dome. The limited assessment that was
conducted showed that unlined concrete surfaces, such as the floor and the walls,
appeared to be in good condition with no spalling noted.
Page 3 of 5
During the design phase, four (4) active Digesters (Digesters K, S, N, & O) were out of
service at Plant 2. Information from these Digesters was used to supplement the limited
data a result of the Digester “O” assessment conducted. The Digester “O” Project
proceeded in an expedited manner.
After the lining system had been removed from the interior portion of the dome, the
contractor was required to conduct a structural assessment. The assessment included
physical sampling and chemical testing for strength and general soundness. Following this assessment, the sand-blasting operation was started. pH values observed during the sand blasting did not match the pH values predicted during the condition
assessment. Contract specified pH values, greater than 9.0 (nine), were not recorded at
the test locations. Despite having removed up to the (1) one inch specified in the
contract another ¼” of concrete must be removed. The extra concrete removal is beyond the Scope of Work per specifications.

Change orders one (1) through four (4), indicated above, are required to complete the planned repair work. A request for price has been requested of the contractor. The
contractor’s fee proposal is currently under review by OCSD staff. The merit of each
request/item has yet to be determined.
Filanc has submitted two (2) other Requests for Changes (Abrasive Blast #3 & #4) that imply additional sand-blasting beyond the original scope of work is required. The cost
total for the two (2) additional requests is approximately $450,000. Staff is reviewing
these claims for merit. Consequently, this amount has not been included in the
increased contingency amount requested as part of this Agenda Report.
The increased contingency amount needed is summarized as follows:

Recently, the Engineering Department’s Asset Management staff has collaborated completed an evaluation of alternatives with regards to the aging sludge Digesters at both Plants. The options evaluated included replacement of the digester domes versus
Digester dome rehabilitation. This will extend Digester life by twenty (20) years.
Page 5 of 5
According to the study, the actual cost of dome rehabilitation is estimated to be approximately $900,000 versus dome replacement of approximately $1,400,000.

SUBJECT: PURCHASE OF LIQUID OXYGEN FOR PLANT No. 2 OXYGEN
ACTIVATED SLUDGE PROCESS
GENERAL MANAGER'S RECOMMENDATION
Authorize the General Manager to competitively bid and subsequently award a contract
for liquid oxygen, Specification C-2011-506BD, to the lowest responsible and responsive bidder, for a one-year period, March 1, 2012 through February 28, 2013, for a total
annual amount not to exceed $750,000.
SUMMARY
Staff is implementing a recommendation from the recently completed Plan of Operation
for Secondary Treatment (POST) to discontinue use of the current cryogenic technology
used to produce oxygen for Plant No. 2’s oxygen activated sludge secondary treatment process and replace it short-term (3 to 7 years) with delivery of liquid oxygen and
potentially long-term with a more cost effective technology. Staff estimates annual
savings in excess of $800,000 by converting to liquid oxygen.
The Board-approved upgrade of the liquid oxygen storage and delivery system is currently in progress and the upgraded system is expected to be in-service and
providing a continuous supply of liquid oxygen beginning March 2012. At that point, the
operation of the cryogenic oxygen generation plant will cease and the secondary facility
will rely entirely on the liquid oxygen supply.
PRIOR COMMITTEE/BOARD ACTIONS
July 2011 – Authorization for Air Products to refurbish the liquid oxygen storage and
delivery system, for a total amount not to exceed $1,300,000; and approval of a contingency of $260,000 (20%) for the liquid oxygen refurbishment.
ADDITIONAL INFORMATION
As a majority of the newly installed/upgraded components of the liquid oxygen system
would be covered under warranty by Air Products, Inc. for a one-year period upon
Page 2 of 2
installation, only a one-year liquid oxygen supply contract with no additional renewals is proposed. The maintenance of the liquid oxygen system will be included as part of the
future liquid oxygen supply contract.

additional amount of $20,000 increasing the total amount not to exceed $1,291,814.
March 2011 - Authorized to negotiate an Amendment to the Professional Design Services Agreement with Black & Veatch for additional design services for the Outfall
Land Section and Ocean Outfall Booster Station Piping Rehabilitation, Project
No. J-112.
December 2009 - Approved a Professional Design Services Agreement with Black & Veatch for Outfall Land Section and Ocean Outfall Booster Station Piping Rehabilitation,
Project No. J-112, providing for engineering design services for an amount not to
exceed $1,271,814, with a contingency of $127,181.
ADDITIONAL INFORMATION
The Phase 1 bid package, entitled Contract No. J-112A OOBS to Surge Tower No. 2, is
currently complete and is now out for bid. This work includes repair of the OOBS
suction and discharge piping and the above-grade portion of the on-site outfall between OOBS and Surge Tower No. 2.
The schedules for the two projects are integrally linked and must be carefully
coordinated because of Outfall system capacity limitations. The Orange County
Sanitation District (Sanitation District) plans to complete the Phase 1 work during the non-rainy season, which is typically April to October, when it is safest to isolate portions of the outfall system. If the Sanitation District elects to proceed with the Phase 2
project, construction will also take place during the non-rainy season.
Page 3 of 3 797918.1
Staff is seeking to accelerate the Phase 1 project schedule to allow time between Phase 1 repair construction and the possible Phase 2 construction project in case of unforeseen construction delays. Considering the expected time to review shop
drawings, fabricate the sampling trailer, and perform the corrosion work on the on-site
outfall under Phase 1 by the end of August 2012, staff believes the Contractor’s Notice
to Proceed (NTP) should be issued at the beginning of January 2012. Based on advertising for bids on November 18, 2011, the earliest time to issue a NTP is January 9, 2012, which would require that the Board of Directors authorize the General Manager
to approve the plans and specifications and award the construction contract. Waiting
until the end of January for the Board of Directors to award the construction contract
under the normal approval process would risk the Sanitation District not meeting the August 2012 completion date. It is important to note that the Phase 1 schedule already assumes that double shifts will be required to complete some of the critical work in order
to meet the proposed schedule. There is little room for error or handling of unforeseen
construction delays.
In order to minimize the risk of system failure and unforeseen construction issues that would affect the scheduling issues between the Phase 1 and Phase 2 project
schedules, it is recommended that the General Manager be authorized to award the
construction contract as soon as possible after receipt and review of bids for Phase 1.
It is anticipated that the award of a Professional Consultant Services Agreement would be requested at the January Board of Directors’ meeting per the normal award process.
CEQA
The Phase 1 work has been determined to be categorically exempt in accordance with Section 15301 (b). A notice of exemption was filed on April 14, 2011.

AGENDA REPORT Item Number 7 Item Number
Orange County Sanitation District
FROM: James D. Ruth, General Manager Originators: James D. Herberg, Assistant General Manager
Edward M. Torres, Director of Operations and Maintenance
SUBJECT: OCEAN MODELING OF RECEIVING WATERS
GENERAL MANAGER'S RECOMMENDATION
A. Authorize the General Manager to negotiate and award a sole source service
agreement to University of California, Los Angeles to provide calibration
services for the Regional Ocean Modeling System for an amount not to exceed $71,000;
B. Approve a contingency of $7,100 (10%);
C. Authorize the General Manager to negotiate and award a sole source service agreement to Remote Sensing Solutions, Inc. to provide development services for
the Regional Ocean Modeling System for an amount not to exceed $150,000; and,
D. Approve a contingency of $15,000 (10%).
SUMMARY
The Regional Ocean Modeling System (ROMS) is a computer model used by the
scientific community to study currents, ecosystems, and sediment movement in various coastal regions. ROMS has been developed for Southern California through the
cooperative efforts of the University of California, Los Angeles (UCLA) and the Jet
Propulsion Laboratory (JPL) at the Center for Earth Systems Research, based at UCLA.
Financial support for the ROMS development and maintenance costs has been
provided by the Southern California Coastal Ocean Observation System (SCOOS). The proposed service agreement includes an enhancement of the ROMS model specifically
for Huntington Beach and Newport Beach coastal waters to provide and incorporate a
higher resolution model into an existing operational model that can be used as a
predictive and planning tool.
The work to update this model is divided between three contractors performing the
work. UCLA will provide calibration services and Remote Sensing Solutions (RSS) will
take the calibrated data to develop the high-resolution model. A third contractor, the
University of Southern California (USC), has already started collecting field data and
current measurements needed to calibrate the model.

Staff believes that the development of this model will save significant costs by providing
advanced prediction of plume migration to better target offshore sampling and
monitoring as well as reducing the potential number of pre-emptive beach postings and closures. In addition, the Regional Water Quality Control Board (RWQCB) or Orange County Health Care Agency (OCHCA) would likely require increased off-shore sampling
by boat if the ROMS model is not included as part of the monitoring plan.
Once developed, the high-resolution ROMS module will provide several on-going benefits to the Sanitation District: (1) report existing and predict future wastewater plume size and location at both the 78-inch and 120-inch outfalls, particularly in
response to questions of the discharge’s impact on recreational waters; (2) supplement
the existing effort to understand the recent impacts of the discharge on the area near
the 120-inch outfall; (3) provide data to direct future decisions whether or not to continue disinfection of the effluent; and (4) be used as a mitigation measure should disinfection practices cease.
Staff will also negotiate with the RWQCB and Environmental Protection Agency (EPA)
to include development of the ROMS model as part of the Strategic Process Study component of the Sanitation District’s NPDES Permit.
The contractors selected for these tasks are uniquely qualified to provide these services
as they are the developers of the west coast adaptation of ROMS used by SCCOOS
and the Central and Northern California Ocean Observation System (CeNCOOS). These services are being requested as sole source actions since there are no known alternatives for obtaining this modeling data and oceanographic research.
PRIOR COMMITTEE/BOARD ACTIONS
None.
ADDITIONAL INFORMATION
The contractors working with the Sanitation District on this project include laboratories from USC, UCLA, and RSS. Sole sources service agreements will be required for each of these organizations since they have unique technical capabilities, expertise in
Southern California, and monitoring equipment for updating and calibrating the ROMS
model owned and operated by NASA/JPL. Using UCLA and RSS also allows the
Sanitation District to leverage SCCOOS’s ongoing financial support of ROMS. BUDGET/DELEGATION OF AUTHORITY COMPLIANCE
This request complies with authority levels of the Sanitation District’s Delegation of
Authority. This item has been budgeted and the budget is sufficient for the recommended action (FY 2011-12, Pg. A-13, Line 138, Operational Research).

AGENDA REPORT Item Number 8 Item Number
Orange County Sanitation District
FROM: Jim Herberg, Assistant General Manager
Originator: Jim Colston, Environmental Compliance Manager
SUBJECT: Regulatory Update
GENERAL MANAGER'S RECOMMENDATION
Information Only Item
SUMMARY
Staff will provide a brief presentation of several key proposed regulatory initiatives
facing the Orange County Sanitation District.
PRIOR COMMITTEE/BOARD ACTIONS
December 2011 – Information Item – Regulatory Update
ADDITIONAL INFORMATION
Key regulations that will be discussed:
Assembly Bill 32 (2006) requires large greenhouse gas (GHG) emitters to reduce
emissions by at least 20% by 2020. The Air Resources Board (ARB) is continuing with
the implementation of the approved AB 32 Scoping Plan, which includes modifications
to the current mandatory regulation for reporting Greenhouse Gases and the cap-and-
trade regulation. As it stands today, Publicly Owned Treatment Works including the Orange County Sanitation District (OCSD) are exempted from the cap-and-trade
program, and would remain under command and control rules to be developed in
accordance with the Scoping Plan to reduce GHGs from wastewater delivery and
treatment.
Federal Tailoring Rule requires large GHG-emitting facilities, such as OCSD, to apply
new source review requirements when building new or expanding existing processes
and facilities. In March 2011, EPA announced it would defer, for three years, GHG
permitting requirements for carbon dioxide emissions from renewable fuel (biogenic)
sources such as OCSD’s Central Generating System (CGS) engines.
Form No. DW-102.2 Page 2
South Coast Air Quality Management District (SCAQMD) proposes amendments to Rule 1110.2, which covers emissions from engines such as OCSD’s co-generation
facilities. OCSD is ahead of the curve, having completed a successful technology
demonstration project during 2011 on one engine.
State Water Resources Control Board (SWRCB) is planning to amend the California Ocean Plan, addressing desalination facilities, brine disposal, and water quality
monitoring.
Constituents of emerging concern (CECs) are the topic of SWRCB expert panels to evaluate CECs that might impact Water Recycling and Coastal Water Resources. In the near term, required monitoring for these constituents is expected.
EPA issued a preliminary Draft Policy for Whole Effluent Toxicity (WET) Assessment
and Control, which focuses on the new Test Significant Toxicity. SWRCB may be implementing this test method. In addition, the EPA is moving forward to reduce mercury for industries including dental clinics. OCSD is assessing development of a
source control program for mercury that will focus on these facilities.
Draft 2011 Sanitary Sewer System (SSS) Waste Discharge Requirement (WDR) Order was released by SWRCB, which public comment period ended on April 29, 2011. The purpose of the WDR is to provide consistent statewide requirements for quantifying and
reducing both the number of Sanitary Sewer Overflows (SSOs) and the volume of
wastewater spilled in the state. The draft WDR includes, among other additional
requirements, mandatory reporting of private spills and enrollment of private and federal sewer systems that meet qualifications. SWRCB will release a letter in December 2011to respond to public comments and will schedule a public workshop in January
2012. An adoption hearing will be scheduled sometime March/April 2012.
