City of Santa Ana Environmental Checklist OCSD facilities are required to comply with the Santa Ana RWQCB wastewater treatment requirements, and to maintain and follow the MS4 permit, which is the U.S. Environmental Protection Agency (EPA) NPDES permit that regulates discharge of treated effluent into receiving waters (e.g., the Santa Ana River Basin). In 2002, the OCSD adopted an 18-year Capital Improvement Program (CIP), which identified 125 projects related to upgrading and repairing wastewater facilities in accordance with the wastewater treatment requirements of the Santa Ana RWQCB (OCSD 2002). These projects are intended to assure that facilities continue to meet or exceed the wastewater treatment requirements established by the Santa Ana RWQCB. As part of the project approval process, the project applicant would be required to provide all onsite sewer infrastructure and pay appropriate sewer system connection fees. Existing City Public Works Department requirements would ensure that wastewater treatment requirements of the RWQCB are not to be exceeded. Therefore, wastewater generated by the proposed project would not cause OCSD to exceed wastewater treatment requirements of the Santa Ana RWCQB. As such, project impacts on wastewater treatment requirements would be less than significant, b.

Less-than-Significant Impact. Water Facilities. The City of Santa Ana obtains water from two sources: groundwater and imported water. Approximately 62% of the City's water supply is derived from groundwater that is pumped to the surface from 20 City-operated wells. The other 38% of water is imported from the Metropolitan Water District of Southern California (City of Santa Ana 2010). The Metropolitan water is treated at either the Robert B. Diener Filtration Plant located in YDrba Linda or the Weymouth Filtration Plant in La Verne before being delivered to the city. There are a total of seven Metropolitan connections located in the city. The City of Santa Ana 2005 Urban Water Management Plan projected water supplies to total approximately 37,120 afy and 20,140 afy from groundwater production and Metropolitan import, respectively (City of Santa Ana 2005). The Orange County Groundwater Basin underlies the north half of Orange County beneath broad lowlands. The groundwater basin generally operates as a reservoir in which the net amount of water stored is increased in wet years to allow for managed overdrafts in dry years. The basin is recharged primarily from local rainfall (greater in wet years), base flow from the Santa Ana River (much of which is actually recycled wastewater from treatment plants in Riverside and San Bernardino Counties), imported water percolated into the basin, and recycled wastewater directly recharged into the basin (City of Santa Ana 2005). The City is in compliance with the Safe Drinking Water Act and monitors regulated and unregulated compounds in its water supply and, in years past, the water delivered to the City meets the standards required by the state and federal regulatory agencies. Additionally, OCWD which manages the Orange County groundwater basin conducts a comprehensive water quality monitoring program which includes source water protection; surface water monitoring; constructed wetlands; public outreach; and regulation (City of Santa Ana 2005). Both the Robert B. Diemer Filtration Plant and F.E. Weymouth Treatment Plant are one of the largest filtration plants in the United States. They each deliver up to 520 million gallons per day.
