City of Santa Ana -Park View at Town and Country Manor Draft EIR HVdrology and program; a chemical monitoring program for "non- visible" pollutants to be implemented if there is a failure of BMPs; and a sediment monitoring plan if the site discharges directly to a water body listed on the 303(d) list for sediment. Section A of the Construction General Permit describes the elements that must be contained in a SWPPP." BCT is an acronym for Best Control Technology. BAT is an acronym for Best Available Technology. Santa Ana Regional Water Quality Control Board (SAR WQCB) Municipal Separate Storm Sewer (MS4) Permits The SARW QCB issued a MS4 storm water permit, WDR Order No. R8- 2002 -0012, NPDES Permit No. CAS618036, to 16 co- permitees within the Santa Ana region, including the City of Santa Ana. Whereas the GISP and GCP are issued statewide, MS4 permits are issued by local Regional Boards in order to provide permits with the means to address storm water quality issues specific to the local watershed or region. As a result, MS4 permits are at a more prescriptive level of regulation, requiring permittees to develop and implement a storm water management program with the goal of reducing the discharge of pollutants to the maximum extent practicable (MEP). The MEP standard is a more stringent performance standard than BCT /BAT established for both the GISP and GCP. The storm water management program or Municipal Storm Water Management Program (MSWMP), as it is referred to in the Santa Ana region, must specify SARWQCB- approved BMPs to address the following program areas: public education and outreach, illicit discharge detection and elimination, construction and post - construction, and good housekeeping for municipal operations. Local Water Quality Regulations Since 1990, the County of Orange has cooperated with Orange County cities (the Permittees) in complying with the NPDES permits issued by the Santa Ana and San Diego RWQCBs. The result of this cooperation has been the development of numerous storm water programs that have been integrated into the area -wide Drainage Area Management Plan (DAMP). The County believes this common approach provides the most efficient and effective means of reducing storm water and urban runoff pollution to meet permit requirements. The DAMP contains model program guidance that was developed through a collaborative effort among all Permittees, including the County, as well as interested agencies, organizations, and the public. The DAMP requires that each Permittee prepare a Local Implementation Plan (LIP) as an appendix to the DAMP. The City of Santa Ana's LIP describes the activities that the City has previously undertaken and is currently undertaking to meet the requirements of the Third Term Permits and to make meaningful improvements in urban water quality. The LIP is intended to serve as the basis for City compliance during the five -year period of the Third Term Permit; however, the LIP is subject to modifications and updates as the City determines necessary, or as directed by the RWQCB.
