ISSUE
The Board of Directors'authorization is required for the General Manager to execute a technical consulting
services agreement in an amount exceeding $200,000.
BACKGROUND
Central San's Treatment Plant operates under a Title V Major Facility Review Permit issued by the Bay
Area Air Quality Management District (BAAQMD) and is subject to additional local, state, and federal air
regulations not captured in the Title V permit. BAAQMD recently implemented new air regulations aimed
at reducing public health risks from toxic air contaminants emissions, which are described below:
June 2, 2022 Regular Board Meeting Agenda Packet- Page 62 of 236
Page 2 of 4
BAAQM D Regulation 11, Rule 18 Health Risk Assessments
BAAQMD Regulation 11, Rule 18: Reduction of Risk from Air Toxic Emissions at Existing Facilities
(Rule 11-18) requires that facilities found to pose a significant health risk to nearby residents and off-
site workers reduce their toxic air contaminant emissions and associated health impacts. Previously,
Central San worked with Black and Veatch to develop a baseline treatment plant health risk
assessment (HRA) model and evaluate risk reduction strategies. The internal HRA helped Central
San gather intelligence prior to the official Rule 11-18 HRA. The new consultant(s)will update the
treatment plant air dispersion model and the baseline HRA model with the most recent fuel throughput
and meteorological data and update risk reduction HRA scenarios to prepare for Rule 11-18
compliance.
In addition to HRA modeling services, the consultant(s) may need to provide technical support during
the official Rule 11-18 HRA process. Under Rule 11-18, BAAQMD will publish facilities' HRA results
and risk reduction plans for public comment. Central San may ask the consultant(s)to provide support
that may include, but is not limited to, a review of BAAQMD's HRA, development support of Central
San's Rule 11-18 risk reduction plan, post-capital improvement HRA modeling to demonstrate resulting
health risk reductions after wet scrubber installation, as well as support during Rule 11-18 HRA and risk
reduction plan public comment period.
BAAQM D Regulation 2, Rule 5 Health Risk Assessments
I n December 2021, BAAQMD amended Regulation 2, Rule 5 (Rule 2-5) risk reduction
requirements, which lowered the cancer risk limit to six in a million for projects with new and modified
emissions sources located in and within 1,000 feet of overburdened communities. The southern
part of the treatment plant, which includes the Solids Conditioning Building that houses the furnaces
and other combustion equipment, is located within 1,000 feet of an overburdened community across
from Highway 4. 1 n the near term, Rule 2-5 amendments will affect the permitting process of the
Solids Handling Facility Improvements Project, Phase 1 A, which will replace critical solids handling
and emissions abatement equipment. Therefore, a new HRA is needed to evaluate project-specific
health risks to assist with the permitting of the Solids Handling Facility Improvements Project. The
consultant(s)will update the baseline HRA on the furnaces and confirm health risk reduction
associated with the wet scrubber replacement. During the permitting process, BAAQMD will
conduct the official HRA prior to issuing an Authority-to-Construct permit. The consultant(s)will be
asked to review and confirm BAAQMD's HRA findings. Public notification may be required for
certain projects subject to Rule 2-5 HRAs.As such, it is imperative for Central San to determine
project-specific health risk impacts and be prepared to address any potential public questions or
concerns.
Additionally, the consultant(s) may be asked to perform greenhouse gas evaluations for the treatment
plant and on incineration as described below:
Scientific Review of Senate Bill (SB) 1383 Lifecycle Greenhouse Gas Analysis
SB 1383 establishes a statewide effort to reduce emissions of short-lived climate pollutants by
reducing organic waste disposal 50% by 2020 and 75% by 2025. Starting in January 2022, all
jurisdictions will be required to divert organic materials away from landfills and into recycling and
recovery activities. Currently, incineration of sewage sludge does not constitute a reduction in landfill
disposal. CalRecycle, the oversight agency for SB 1383, will consider additional technologies that are
not currently considered a reduction in landfill disposal. For a technology or process to constitute a
reduction in landfill disposal, the permanent lifecycle greenhouse gas emission reductions must be
equal to or greater than the emission reductions from avoidance of landfilling or composting organic
waste. Submittal of an application to CalRecycle is required to consider a technology a reduction in
landfill disposal. CalRecycle will then evaluate the application in consultation with the California Air
Resources Board.

Central San plans to submit an application requesting CalRecycle to consider incineration of biosolids
as a reduction in landfill disposal. Staff is currently finalizing a lifecycle greenhouse gas emission
analysis on incineration and ash disposal in comparison to landfill disposal of dewatered sewage
sludge. This analysis will be scientifically reviewed by the consultant(s) prior to submission to
CalRecycle.
Lastly, Central San may utilize consultant support for the upcoming Title V permit renewal and BAAQMD
Authority-to-Construct permits. Central San submitted a Title V Major Facility Review Permit renewal
application to BAAQMD in 2019, and BAAQMD recently began the review of the Title V permit renewal
application. Central San is currently operating under the 2015 Title V Major Facility Review Permit until a
new Title V permit is issued. Central San may require the consultant's assistance during the renewal
process, specifically with draft permit review and emissions calculations verifications. Additionally, the
consultant's assistance may be needed with obtaining Authority-to-Construct permits from BAAQMD for
capital improvements that would impact air emissions.
I n February 2022, Central San issued a Request for Qualifications to four firms for as-needed air quality
compliance, greenhouse gas, and health risk assessment services. Central San received two
Statements of Qualifications and interviewed Yorke Engineering, LLC. (Yorke) and GHD, Inc. (GHD).
While both firms can provide all of the aforementioned air quality related services, each firm displayed
unique capabilities in certain air quality related specialties.
Yorke is a small-sized specialty firm with expertise in air quality projects, HRAs, and BAAQMD permit
applications and renewals. The firm has worked with over 60 Title V facilities and completed over 300
HRAs in California. Every year, Yorke completes over 1,000 air quality projects in California. Yorke
recently assisted a facility under Phase 1 of Rule 11-18 with the official HRA and evaluated risk reduction
scenarios. Yorke has worked with other wastewater treatment plants in the Bay Area, such as East Bay
Municipal Utility District, Delta Diablo, Union Sanitary District, the City of San Mateo, and the City of Santa
Rosa, on Title V permitting and HRA projects. Yorke has assisted Central San with air quality compliance
projects in the past.
GHD is an international firm with engineering, environmental, and construction expertise and has
toxicologists on their staff to assist with potential health risk related concerns that may arise during Rule
11-18 HRA. GHD is an expert in greenhouse gas management, with extensive experience in emissions
evaluations as well as reduction and net zero strategies. GHD is currently assisting Central San with the
Solids Handling Facility Improvements, Phase 1, and has experience assisting other biosolids
incineration plants with their Title V permits.
The combined capabilities and experience of both Yorke and GHD will help better position Central San to
address any potential air quality challenges and public or regulatory concerns that may arise during the
permitting and health risk assessment processes. Therefore, staff recommends establishing agreements
with both Yorke and GHD to support Central San's near-term needs.
California Environmental Quality Act(CEQA): Staff has concluded that these actions are exempt from
CEQA under District CEQA Guidelines Section 15262 since they allow for further planning and feasibility
studies for possible future actions which Central San has not approved, adopted, or funded, and the
outcome of these tasks will not have a legally binding effect on later activities. Approval of these actions
will establish the Board's independent finding that these agreements are exempt from CEQA. Central
San will conduct an environmental evaluation of any environmental-altering, physical project that is
proposed in the future as a result of these studies to determine the need for any additional CEQA
documentation.

ALTERNATIVES/CONSIDERATIONS
The Board could decide to reject the proposal, but based on the qualifications at this time, we would likely
not receive additional proposals if the RFP was republished. Therefore, this alternative is not
recommended by staff.
FINANCIAL IMPACTS
The total estimated cost for the agreement with Yorke is $780,000, and the total estimated cost for the
agreement with GHD is $500,000 if both agreements are fully utilized. Both agreements will cover as-
needed services over the next five fiscal years (FYs 2022-27) and will be funded by the Environmental and
Regulatory Compliance Division under the Regulatory Compliance Section's FY 2022-2027 budgets.
COMMITTEE RECOMMENDATION
The Real Estate, Environmental and Planning Committee reviewed this item at its May 18, 2022 meeting
and recommended approval.
RECOMMENDED BOARD ACTION
Staff recommends the following Board action:
A. Find the agreements are exempt from CEQA; and
B. Authorize the General Manager to execute two professional consulting services agreements with:
1) Yorke Engineering, LLC. in an amount not to exceed $780,000 and 2) GHD, Inc. in an amount not
to exceed $500,000, each for a five-year period (FYs 2022-27)to provide as-needed air quality
compliance, greenhouse gas, and health risk assessment services.
