Notice This meeting was held in accordance with the Brown Act as in effect under the State Emergency Services Act, the Governor's Emergency Declaration related to October 1, 2020 Regular Board Meeting Agenda Packet- Page 86 of 104 Page 3 of 14 Real Estate, Environmental & Planning Committee Minutes September 21, 2020 Page 2 COVID-19, and the Governor's Executive Order N-29-20 issued on March 17, 2020 that allowed attendance by Board Members, District staff, and the public to participate and conduct the meeting by teleconference, videoconference, or both. The agenda included instructions for options in which the public could participate in the meeting. 2. Call Meeting to Order Chair Pilecki called the meeting to order at 8:07 a.m. 3. Public Comments None. 4. Agenda Items *a. Receive update on Solar Energy Project procurement schedule Ms. LaBella provided a brief presentation regarding the Solar Energy Procurement Schedule (attached). She stated that a Position Paper will be brought to the Board at the October I**meeting to set a public hearing for November 5, 2020 to consider awarding a Power Purchase Agreement (PPA). Member McGill inquired what were the attributing factors for better projected savings on this new solar project as compared with Central San's previous PPAs at the Collection System Operations (CSO) facility and the Household Hazardous Waste Collection Facility (HHW). Ms. LaBella stated that the new solar project involves ground-mounted panels, which are cheaper to install than the installations at CSO and HHW. In addition, she added that the price for solar panels has come down over the years. Mr. Driver added that compared to previous District projects, the price is less due to the much larger project size. Chair Pilecki requested a news release occur after the PPA is approved. **Post-Meetinq Addendum The public hearing for the solar project will be set on October 15 for a November 5, 2020 hearing. COMMITTEE ACTION: Received the update. *b. Receive update on request from Marathon Refinery to consider potential wastewater discharge to Central San Mr. Petit presented an overview of the preliminary evaluation of possible discharge streams that Central San may receive from the refinery, as attached. There was a lengthy discussion about the various types of streams October 1, 2020 Regular Board Meeting Agenda Packet- Page 87 of 104 Page 4 of 14 Real Estate, Environmental & Planning Committee Minutes September 21, 2020 Page 3 the District could be receiving and be able to treat. Staff ran two computer BioWin models of stream, labeled 1 (full strength, containing high biological oxygen demand and nutrient load) and 5 (domestic strength equivalent following pre-treatment). Preliminary results indicated that stream 1 would be difficult to treat at the District without plant modifications for the activated sludge secondary process, and that stream 5, with certain caveats and depending on more details about the waste characteristics, may be able to be received. Mr. Petit answered several questions from the Committee. Member McGill inquired if Marathon Refinery was included in the District's service area and was paying property taxes even without using the service. Mr. Bailey stated that he believed refineries are subject to property tax. Staff would have to check if Marathon pays ad valorem taxes. Mr. Leavitt stated that portions of the Marathon property are included in Central San's boundaries and/or within its sphere of influence. A discussion on the costs and financial impact on the District followed. Mr. Bailey advised that if the Board were to decide to accept the request and Central San treated the discharge, neither the ratepayers, nor the District's National Pollutant Discharge Elimination System (NPDS) permit should and would not be affected. COMMITTEE ACTION: Received the update and provided input to staff. *c. Receive verbal update on status of Electric Vehicle Charging Stations, District Project 8252; and a recreational vehicle (RV) dumping station proposal Electric Vehicle Charging Stations Ms. LaBella provided a brief update on the project and stated that the County has no interest at this time in adding electric vehicle charging stations at the fueling station near Central San's treatment plant campus, since they have other locations with access to a greater number of potential users. She inquired of the Committee's interest and direction for staff to continue researching the feasibility to install charging stations within Central San's treatment plant for employee use only. Member McGill opined that staff should not expend any further effort on this matter and instead focus on a holistic overview of other environmental projects. Chair Pilecki offered that staff should spend more time on other projects, such as the RV dumping station and showers for the homeless. October 1, 2020 Regular Board Meeting Agenda Packet- Page 88 of 104 Page 5 of 14 Real Estate, Environmental & Planning Committee Minutes September 21, 2020 Page 4 RV Dumping Station Mr. Lopez provided the Committee with the attached preliminary layout to add a potential RV dumping station on site. The intent is to use a portion of the treatment plant that was formerly used as a contractor's staging area for the dumping station; therefore, the cost would be minimal and the design could be included in a future capital project as an alternate bid item. Mr. Bailey advised that an alumnus from the Central San Citizens Academy reached out to him regarding a need for an RV dumping station. He said it would be a hands-free operation. However, he advised that a there should be a policy provision in place in the event of a spill or discharge. Ultimately, he said the decision rests with the Board. Following discussion of current RV dumping service operations in the District's service area, it was determined that there are only a few such facilities geared toward public use. In response to a question from Member McGill, Mr. Potter advised that with the continued homeless situation, illegal dumping has been a big problem. Chair Pilecki suggested that staff poll customers in the next Pipeline edition to gauge interest for an RV disposal site. He also requested staff contact the thirteen County jurisdictions to determine their support/non-support for a potential RV dumping station. COMMITTEE ACTION: Received the update and provided input to staff. d. Review draft lease terms for use of District-owned property by Contra Costa Topsoil Ms. Gemmell reviewed the presentation included in the agenda material and provided the lease agreement terms. It was noted that the rate will be 10% higher than their current agreement to bring the cost to the present market rate. Reaching the market rate will occur after the fifth year. In response to a question from Chair Pilecki, Ms. Gemmell stated that the tenants are comfortable with the increases. Member McGill requested an update on all District buffer properties at a future meeting. Ms. Gemmell advised that staff intends to bring a buffer property policy to the Administration Committee in the near future. COMMITTEE ACTION: Received the information and provided input to staff. October 1, 2020 Regular Board Meeting Agenda Packet- Page 89 of 104 Page 6 of 14 Real Estate, Environmental & Planning Committee Minutes September 21, 2020 Page 5 e. Receive update on the most recent meeting of the Bay Area Clean Water Agencies (BACWA) Ms. Schectel reviewed the memorandum included in the agenda materials. Ms. Schectel also discussed a technical meeting BACWA held September 18 with the Regional Water Board, at which Mr. Petit made a presentation to the BACWA members and to representatives of the San Francisco Regional Water Control Board during the "Pardee" (named after Pardee Dam East Bay Municipal Utility District) Virtual meeting on nutrients, showing load variability and potential permit implications. Ms. Schectel advised that BACWA is planning the annual meeting for 2021, which will be virtual. She will provide the Committee with the details when available. She also noted the Annual Regional Monitoring Program Annual Meeting will be virtual on October 6, 2020. COMMITTEE ACTION: Received the information. 5. Announcements None. 6.
