City of Pleasanton Recycled Water Project CEQA Addendum Construction activities for this kind of project will typically occur with periodic activity peaks, requiring brief periods of significant effort followed by longer periods of reduced activities. In order to characterize and analyze potential construction impacts, the City has assumed that the project would be constructed by two (2) crews of 10-15 workers each and would proceed at a rate of approximately 500-1,000 feet per day. However, specific details may change or vary slightly. Staging areas for storage of pipe, construction equipment, and other materials would be placed at locations (primarily empty parking lots) that would minimize hauling distances and long-term disruption. 2.3.2 Compliance with CCR Title 22 and State Board's Recycled Water Policy The Proposed Project/Action will be designed and operated in accordance with the applicable requirements of CCR Title 22 and any other state or local legislation that is currently effective or may become effective as it pertains to recycled water. The State Board adopted a Recycled Water Policy (RW Policy) in 2009 to establish more uniform requirements for water recycling throughout the State and to streamline the permit application process in most instances. As part of that process, the State Board prepared an Initial Study and Mitigated Negative Declaration for the use of recycled water. The newly adopted RW Policy includes a mandate that the State increase the use of recycled water over 2002 levels by at least 1,000,000 AFY by 2020 and by at least 2,000,000 AFY by 2030. Also included are goals for storm water reuse, conservation and potable water offsets by recycled water. The onus for achieving these mandates and goals is placed both on recycled water purveyors and potential users. The State Board has designated the Regional Water Quality Control Boards as the regulating entities for the Recycled Water Policy. In this case, the San Francisco Bay Regional Water Quality Control Board (San Francisco RWQCB) is responsible for permitting recycled water projects throughout the San Francisco Bay Area, including the City of Pleasanton. The Proposed Project/Action will be provided high quality unrestricted use tertiary treated recycled water from the City of Livermore Waste Water Treatment Facility and the DSRSD/EBMUD Recycled Water Authority (DERWA) and made available to users within the City. All irrigation systems will be operated in accordance with the requirements of Title 22 of the CCR, the State Board Recycled Water Policy, and any other local legislation that is effective or may become effective as it pertains to recycled water and any reclamation permits issued by the San Francisco RWQCB. Reclamation permits typically require the following: • Irrigation rates will match the agronomic rates of the plants being irrigated; • Control of incidental runoff through the proper design of irrigation facilities; • Implementation of a leak detection program to correct problems within 72 hours or prior to the release of 1,000 gallons whichever occurs first; • Management of ponds containing recycled water to ensure no discharges; and • Irrigation will not occur within 50 feet of any domestic supply wells, unless certain conditions have been met as defined in Title 22. 2.3.3 Operational and Maintenance Plans The City does not currently, but intends to, have operations, maintenance, and support staff to distribute recycled water. The City has completed operations, maintenance, and treatment agreements with the City of Livermore and DERWA to provide the City of Pleasanton with recycled water. As it is currently agreed, the City of Livermore and DERWA would operate and maintain the treatment portion for delivery of recycled water to the City of Pleasanton. Pleasanton would require and enforce an irrigation schedule among its users. This arrangement is referred to as a "water master." The `water master' strategy will vary irrigation schedules in a way that optimizes use of the distribution system. The water master schedule may be modified in the future, but the initial assumptions are outlined below. April 2018 2-3
