Attachment 2 provides an energy dashboard that contains a breakdown of Central San's energy usage for the month of December 2022 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) 2022 Title V Clean Air Act Annual Report Submitted Central San's Treatment Plant operates under 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 2022, Central San complied with all Title V and PTO permit requirements except for four compliance deviations: a bypass event on Furnace 2, an opacity deviation on Furnace 2, an inoperative monitor occurrence on the Cogeneration nitrogen oxides monitor, and an inoperative monitor occurrence on the Auxiliary Boiler 1 landfill gas flowmeter. BAAQMD issued one Notice of Violation in 2022 for the Furnace 2 bypass event. Regulatory Compliance staff works closely with the Operations and Maintenance divisions to identify the root cause of each compliance deviation, implement any necessary corrective actions, and communicate the findings and response actions to BAAQMD. The 2022 Title V Clean Air Act Annual Report was submitted to BAAQMD by January 27, 2023. A copy of the report is available upon request from Central San's Secretary of the District.
