FROM: James D. Herberg, General Manager

SUBJECT: MATERIALS TESTING, INSPECTION, AND OTHER GEOTECHNICAL
TESTING SERVICES
GENERAL MANAGER'S RECOMMENDATION
Approve Amendment No. 1 to the Professional Services Agreement, PSA2013-001,
with Sequoia Consultants, Inc. to provide on-call Materials Testing, Inspection, and
other Geotechnical Testing Services for Collection System and Treatment Plant
projects, for an amount not to exceed $100,000, increasing the total contract amount
not to exceed $300,000.
SUMMARY
In June 2013, the Board approved a contract with Sequoia Consultants, Inc. (Sequoia)
to provide on-call Materials Testing, Inspection, and other Geotechnical Testing
Services to support the ongoing CIP construction efforts. This procurement resulted in
an award to a panel of three companies to provide these services and was a
competitive selection process. The contracts were awarded for a three-year term not to
exceed $200,000 for each of the three firms. Unit rates were locked in at that time.
These on-call materials testing, inspection and geotechnical testing service contracts
augment our construction management staff to provide laboratory testing and certified
sampling of construction materials and soils to ensure projects are constructed to
comply with specified standards.
The contract amounts for the on-call support contracts are determined based upon
future project information known at the time and forecasting the anticipated level of
effort to support the projects. With the amount of construction and oversight needed for
quality assurance over the last two-year period, especially with the demanding
geotechnical needs of the newly installed pipelines in Newport Beach, the originally
estimated contract amount to complete the contact term are insufficient.
Based upon a revised forecast of the construction through June 2016, an Amendment in
the amount of $100,000 is needed to provide the testing and inspection services
required to support this work.
A new Request for Proposal for the on-call testing and inspection services will be
advertised over the next few months resulting in new contracts being recommended for
approval to the Board early next year in order to have these take effect in July 2016 for
a new three-year term.

FROM: James D. Herberg, General Manager
Originator: Ed Torres, Director of Operations & Maintenance
SUBJECT: ADDITIONAL SERVICES AND INCREASE TO AGREEMENT J-79-1A
FOR CENTRAL GENERATION AUTOMATION/CONTINUOUS
EMISSIONS MONITORING SYSTEMS (CEMS)
GENERAL MANAGER'S RECOMMENDATION
Approve additional maintenance services to a Sole Source Purchase Order Service
Agreement, J-79-1A with CEMTEK Environmental for maintenance of the Central
Generation Engines continuous emissions monitoring systems, for an additional amount
of $104,068, for a new total amount not to exceed $361,568, for the contract period
ending November 22, 2017.
SUMMARY
Eight (8) Continuous Emission Monitoring Systems (CEMS) units monitor the exhaust
gases of each operational central generation engine as required by permits from the
South Coast Air Quality Management District (SCAQMD).
The CEMS units and supporting Data Acquisition and Handling Software (DAHS) were
procured from CEMTEK Environmental. The CEMTEK Environmental has been
successfully servicing and maintaining the existing units, and providing calibration
verification reports to SCAQMD since 2008. To comply with the SCAQMD Rule 1110.2
for stationary engines, new emission control equipment is being installed under project
J-111 that includes eight (8) additional CEMTEK sampling points for continuous
emissions monitoring. Since CEMTEK is the sole service provider of the equipment and
is familiar with the original computer code and programing, staff recommends that the
contract for maintenance and reporting services be expanded to cover the additional
equipment being installed under the capital improvement program. This will help ensure
reliability, regulatory compliance, and continued support.
PRIOR COMMITTEE/BOARD ACTIONS
October 2012 — Approval of Contract No. J-79-A renewal, Continuous Emissions
Monitoring System (GEMS). The renewal of a Sole Source Service Agreement with
CEMTEK Environmental was awarded for a total amount of $257,500 for a five-year
period.
September 2008 — Approval of Contract No. J-79-lA awarded to Morrow Meadows for
Continuous Emissions Monitoring System (GEMS). The original maintenance contract
was awarded as part of the project that installed the CEMS.
Page 1 of 2
February 2005 — Approval of Professional Design Services Agreement with Black &
Veatch Corporation to prepare plans and specifications for the Central Generation
Automation, Project No. J-79-1.
ADDITIONAL INFORMATION
During Contract No. J-79-1A, the project that installed the CEMS, the District's standard
for Modicon PLC equipment was enforced. The Modicon PLCs require custom code to
be written by CEMTEK that is held to be proprietary to them. Maintenance or capital
projects involving changes to the code require their involvement.

Odor Complaint Report
Fiscal Year 2015/16 — 111 Quarter
1. Plant No. 1 Treatment Facility Odor Complaint Summary
Plant No. 1 received five (5) attributable odor complaints during the V quarter. The odors were
characterized as putrid, rotten, chemical-like, musty/moldy and sewer gas. The sources of the odor
were believed to be coming from the headworks and trickling filter process areas.
2. Plant No. 2 Treatment Facility Odor Complaint Summary
Plant No. 2 received four (4) attributable odor complaints during the V quarter. It was determined
that the source of the odors may be attributed to the Regional Odor and Corrosion Control annual
performance testing as well as odors produced by digester cleaning efforts. Staff also reported the
trickling filters may have contributed to reported odors.
3. Collection Facilities Odor Complaints— 1*1 Quarter FY 2015/16
OCSD received three (3) attributable odor complaints due to the collection system. Based on our
current upstream sewage conditioning program, our goal for level of service is 12 or fewer

Activated-sludge process — A secondary biological wastewater treatment process where bacteria
reproduce at a high rate with the introduction of excess air or oxygen, and consume dissolved
nutrients in the wastewater.
Benthos— The community of organisms, such as sea stars, worms and shrimp, which live on, in, or
near the seabed, also know as the benthic zone.
Biochemical Oxygen Demand (BOD)—The amount of oxygen used when organic matter undergoes
decomposition by microorganisms. Testing for BOD is done to assess the amount of organic matter in
water.
Biosolids — Biosolids are nutrient rich organic and highly treated solid materials produced by the
wastewater treatment process. This high-quality product can be recycled as a soil amendment on
farm land or further processed as an earth-like product for commercial and home gardens to improve
and maintain fertile soil and stimulate plant growth.
Capital Improvement Program (CIP) — Projects for repair, rehabilitation, and replacement of assets.
Also includes treatment improvements, additional capacity, and projects for the support facilities.
Coliform bacteria—A group of bacteria found in the intestines of humans and other animals, but also
occasionally found elsewhere used as indicators of sewage pollution. E. coli are the most common
bacteria in wastewater.
Collections system — In wastewater, it is the system of typically underground pipes that receive and
convey sanitary wastewater or storm water.
Certificate of Participation (COP) —A type of financing where an investor purchases a share of the
lease revenues of a program rather than the bond being secured by those revenues.
Glossary of Terms and Abbreviations
Contaminants of Potential Concern (CPC) — Pharmaceuticals, hormones, and other organic
wastewater contaminants.
Dilution to Threshold (D!f) — the dilution at which the majority of the people detect the odor
becomes the DrT for that air sample.
Greenhouse gases — In the order of relative abundance water vapor, carbon dioxide, methane,
nitrous oxide, and ozone gases that are considered the cause of global warming ("greenhouse
effect").
Groundwater Replenishment (GWR) System — A joint water reclamation project that proactively
responds to Southern California's current and future water needs. This joint project between the
Orange County Water District and the Orange County Sanitation District provides 70 million gallons a
day of drinking quality water to replenish the local groundwater supply.
Levels of Service (LOS)—Goals to support environmental and public expectations for performance.
NDMA— N-Nitrosodimethylamine is an N-nitrosoamine suspected cancer-causing agent. It has been
found in the Groundwater Replenishment System process and is eliminated using hydrogen peroxide
with extra ultra-violet treatment.
National Biosolids Partnership (NBP) — An alliance of the National Association of Clean Water
Agencies (NACWA) and Water Environment Federation (WEF), with advisory support from the U.S.
Environmental Protection Agency (EPA). NBP is committed to developing and advancing
environmentally sound and sustainable biosolids management practices that go beyond regulatory
compliance and promote public participation in order to enhance the credibility of local agency
biosolids programs and improved communications that lead to public acceptance.
Plume—A visible or measurable concentration of discharge from a stationary source or fixed facility.
Publicly-owned Treatment Works (POTW)— Municipal wastewater treatment plant.
