Public Comments None. 3. Agenda Items a.* Update on recent Reportable Compliance Activities (RCA) Ms. Schecte/explained that due to the new federal SSI 129 regulations, as of March 2016, exercise of the furnace bypass are required to be reported. Since November 2017, there were several reportable incidents, and staff will be meeting with the Bay Area Air Quality Management District February 21, 2018 to determine how to move forward. Mr. Bailey reminded the Committee that there is no systematic failure, these RCAs are simply due to a rule change. Mr. Schmidt reviewed the recent RCAs and provided additional details for each event. He showed a diagram of the multiple hearth furnaces (attached) and responded to questions. COMMITTEE ACTION: Received the update. b.* Review information on wastewater supply versus demand for recycled water Mr. Bailey explained that before staff can explore recycled water options with other agencies, it first must be determined how much wastewater is available. Staff also needs to recognize the agreements that have already been made with local agencies and organizations before exploring additional options. Ms. LaBella and Mr. Frost reviewed the updated presentation (attached) and responded to questions. Mr. Frost explained that the current supply is enough to meet existing commitments, however, our available wastewater supply may be limited in meeting large future project demands depending on the type of water quality required for those projects and depending on how much additional wastewater flow is received in the future due to growth within the service area. Ms. LaBella suggeste� that the Board needs to proceed cautiously in making additional wastewater diversion commitments, if the desired goal is a large-scale recycled water project with year-round demand. Member Nejedly expressed frustration at the lack of progress in providing recycled water to the refineries. Chair Causey suggested remaining open to other recycled water opportunities and considering what the potential benefits would be. Member Nejedly indicated his opposition to the Dublin San Ramon Services District—East Bay Municipal Utility District Recycled Water Authority (DERWA) diversion request.

Update on Residential Fill Station and Truck Fill Program Ms. Gemmell reviewed the information included in the agenda materials. Chair Causey requested a breakdown for the truck fill statistics to show the automatic fill station on Imhoff Drive. Mr. Wyatt reviewed the Residential Fill Station statistics, explaining the overall decrease in usage from 2016. He stated that staff anticipates a growth in numbers if it proves to be another dry year, but fears that there will not be enough staffing to properly handle the increase in customers. COMMITTEE ACTION: Received the update. d. Update on the most recent meeting of the Bay Area Clean Water Agencies (BACWA) Ms. Schecte/stated that no BACWA executive board meeting has been held since December. The BACWA Annual Meeting was held January 19, 2018, which had a regulatory focus and included speakers from the State Water Resources Control Board, the Regional Water Quality Control Board (RWQCB), United States Environmental Protection Agency, and the Bay Area Air Quality Management District. BACWA will hold its next joint meeting with the Regional Water Quality Control Board on March 2, 2018. Division staff has been participating in BACWA committee meetings. She explained that staff is still waiting on the state toxicity plan to come out and that staff is starting to prepare for the implementation of the new The NELAC Institute (TNI) lab standards. BACWA decided not to join a petition asking the RWQCB to remand Central Marie's National Pollutant Discharge Elimination System (NPDES)permit related to the inclusion of satellite collection systems and instead write a letter, which is what California Association of Sanitation Agencies (CASA) is also doing. COMMITTEE ACTION: Received the update. e. Quarterly update on CoCo San Sustainable Farm Ms. Gemmell reviewed the information and site plan included in the agenda materials. Chair Causey stated that this report is fully inadequate and unacceptable. He further stated that unless there is a change in the management of this project, the Board should consider the project's future viability given its configuration. Ms. Gemmell explained that the annual report March 1, 2018 Regular Board Meeting Agenda Packet- Page 171 of 228 Page 5 of 13 Real Estate, Environmental & Planning Committee Minutes February 14, 2018 Page 4 should be available around April 1. Chair Causey stated that without a change in management, he may no longer be able to support the project. Member Nejedly recommended that this report be presented to the full Board immediately. COMMITTEE ACTION: Received the update, and recommended that the Board review this update and make a decision about the future of the project. f. Receive list of Scheduled/Parking Lot items COMMITTEE ACTION: Received and provided input to staff. 4. Announcements a. Ms. LaBella stated that the California WaterFix, commonly referred to as the "twin tunnels project"is transitioning to a phased construction approach and beginning with a single tunnel. The reason for this shift is the lack of funding from water agencies. A recent cost-benefit analysis completed on the project indicates $1.82 in benefit for every$1.00 invested by State Water Project contract holders. b. Ms. LaBella announced that the California Water Commission (CWC) recently issued the public benefit ratio scores to those agencies applying for the water storage grants under Proposition 1. Contra Costa Water District's public benefit ratio has initially come out much lower than they indicated in their application and they are currently ranked 4th out of the 11 viable applications. The next steps are for the applicants to provide additional information to the CWC to substantiate their public benefit claims, along with receiving the remainder of their application scores which are anticipated near the end of the fiscal year. 5. Future scheduled meetings a. Confirm remaining 2018 Real Estate, Environmental & Planning Committee m6eting dates COMMITTEE ACTION: Confirmed meeting dates. 6. Suggestions for future agenda items None. 7. Adjournment— at 3:44 p.m. * Attachment March 1, 2018 Regular Board Meeting Agenda Packet- Page 172 of 228 Page 6 of 13 ATMOSPHERE C.^•C•5•D• Item 3.a.
