ENERGY CONSUMPTION
1) Fourth Quarter Update on Central San's Energy Usage
Central San actively tracks greenhouse (GHG) emissions to optimize the use of energy at
its facilities in the most cost-effective and environmentally responsible manner. The
attached energy dashboard contains a breakdown of Central San's energy usage for the
month of December 2021 along with a comparison of the energy used during the fourth
quarter of the calendar year. The chart shows the cost breakdown of Pacific Gas and
Electric (PG&E) and Marin Clean Energy (MCE) electricity.
ENVIRONMENTAL COMPLIANCE
2) 2021 Title V Clean Air Act Annual Report Submitted
Central San's Treatment Plant has two air quality permits: the annual Permit-to-Operate
(PTO) issued and enforced by the Bay Area Air Quality Management District (BAAQMD),
and the five-year Federal Title V Major Facility Air Permit (Title V Permit) issued and
enforced by both BAAQMD and the United States Environmental Protection Agency.
Central San is required to prepare a comprehensive report annually, summarizing its
compliance status for both the Title V Permit and the PTO.
During the reporting year of 2021, Central San complied with all Title V and PTO permit
requirements except for four permit deviations: a bypass event on Furnace 1, an opacity
deviation on Furnace 1, an inoperative monitor occurrence on the Cogeneration nitrogen
oxides monitor, and an inoperative monitor occurrence on the Auxiliary Boiler 2 landfill
gas flowmeter. BAAQMD issued one Notice of Violation in 2021 for the furnace bypass
event.
Regulatory Compliance staff works closely with the Operations and Maintenance divisions
to identify the root cause of each permit deviation, implement any necessary improvement
actions, and communicate the findings and response actions to BAAQMD.
The 2021 Title V Clean Air Act Annual Report was submitted to BAAQMD by January 31 ,
2022. A copy of the report will be available upon request from Central San's Secretary of
the District.

PROJECT UPDATES
3) Public Bidding of Danville Sewer Renovations, Phase 4, District Project 8466
The Danville Sewer Renovations, Phase 4, is part of the ongoing Collection System
Sewer Renovation Program to replace high maintenance, deteriorated sewers that are at
the end of their useful life. This project will renovate up to 9,200 feet of sewer mains,
primarily clay pipes, within the Town of Danville and unincorporated Alamo service area.
Construction activities will include open-trench, pipe-bursting and cured-in-place pipe
methods within public rights-of-way and private easements. Due to COVID-19, the
community outreach is performed through online resources and posted on the District's
website. Notification letters have been sent to the impacted residents and nearby
neighborhoods.
This project will be advertised and bid in March of this year. The Engineer's estimate is
$4,100,000. More information will be presented when the Board is asked to award the
construction contract at its April 21, 2022 meeting.
