Regulatory compliance is a major goal of the Master Plan. This project memorandum (PM) sets the stage for the overall Master Plan process by establishing the regulatory basis for planning objectives and strategies and describing current and pending regulatory requirements. Regulations pertaining to wastewater discharge, biosolids management, air quality, and regulations that will affect San José/Santa Clara Water Pollution Control Plant (WPCP) land use decisions will be considered. Table 1 summarizes the federal, state, and regional regulations that apply to water quality, air quality, and biosolids disposal/reuse that were evaluated when considering the cross-media impacts of advanced treatment processes. 2.0 WASTEWATER DISCHARGE The WPCP discharges approximately 110 million gallons per day (mgd) of advanced tertiary treated water into the Artesian Slough, which is a tributary to Coyote Creek, which ultimately discharges into South San Francisco Bay. The WPCP is considered a shallow water discharger, since its wastewater is not discharged through a diffuser and it does not receive a
