27 Water Supply During Drought. The California Water Code asks agencies to evaluate their water service reliability by examining the impact of drought on their water supplies and comparing those reduced supplies to water demands. Specifically, agencies should calculate their water supplies during a single dry year and five consecutive dry years using historical records. On March 22, 2021, the State Water Resources Control Board (SWRCB) released a letter to water suppliers reporting the ongoing dry conditions after two years of low precipitation in California, in preparation for statewide drought impacts. Immediately following this release, Zone 7 issued a request for the Tri-Valley community to voluntarily reduce water usage due to the ongoing dry weather and low snowpack conditions. This was followed by a joint news release between Zone 7 and the Retailers (Cities of Pleasanton and Livermore, California Water Service, and Dublin San Ramon Services District) on May 27, 2021, asking customers to reduce water use by 10% compared to the year prior. Within this timeframe, the Governor issued a State of Emergency Proclamation on April 21, 2021, for Mendocino and Sonoma counties due to drought conditions in the Russian River watershed. Then on May 10, 2021, the emergency declaration was expanded to include 39 additional counties, including Alameda County, due to drought conditions within the Klamath River, Tulare Lake Watershed, and Sacramento-San Joaquin Delta. Most recently, on July 8, 2021, the Governor further expanded the drought emergency and requested all Californians to reduce water use by 15 percent to help protect water reserves if drought conditions continue. In response, Zone 7 and the Retailers increased the voluntary conservation request to the Tri- Valley community to 15 percent to further protect available water supply. At its October 5, 2021, meeting, City Council adopted urgency Ordinance No. 2225 declaring a Local Drought Emergency due to the critically reduced water supplies and continued extreme dry weather for the protection of public health, safety, and welfare. Concurrently, City Council adopted Resolution No. 21-1250 declaring a State 2 Water Shortage and mandating water customers reduce their potable water usage by 15 percent. On March 15, 2022, the City Council adopted Resolution No. 22 -1283 activating Stage 2 Drought Rates to achieve the mandatory water conservation target and to offset revenue loss to sustain the City’s Water Enterprise. The heavy rain in early 2023 has significantly helped drought conditions. On March 24, 2023, Governor Newsom ended the 15 percent water conservation target and requirement for water agencies to implement level 2 of their drought contingency plans. On April 18, 2023, the City Council terminated the local drought emergency, the Stage 2 water shortage, and the Stage 2 drought rates concurrent with the Zone 7 Board of Directors’ approval to end its drought emergency and mandatory conservation. On April 19, 2023, the Zone 7 Board of Directors ended its local drought emergency. Regulatory Requirements The water received from Zone 7 and the water produced by the City’s wells is tested, as is required by the State Water Resources Control Board Division of Drinking Water (DDW), to ensure quality water is delivered to all customers within Pleasanton. On October 31, 2022, DDW issued General Order DW 2022-0001-DDW (Order), which beginning the first quarter of 2023 required the City to perform testing for per- and polyfluoroalkyl substances (PFAS), which are contaminants of emerging concern. This Order rescinded and replaced previous PFAS testing orders issued by DDW to the City dating back to 2019. On October 31, 2022, DDW also
