and Water City of Santa Ana - Park View at Town and Country Manor Draft EIR following to the regulated community - small MS4s (those serving less than 100,000 population), public facilities (i.e. military bases, school districts, hospitals, etc.), as well as construction activities disturbing between one and five acres of land. State Water Resources Control Board In the State of California, the SWRCB and local RWQCBs have assumed the responsibility of implementing the US EPA's NPDES Storm Water Program. Under the State's water quality control law, better known as the Porter- Cologne Water Quality Act (Water Code Sections 13000 et seq.), the SWRCB is granted control over California's water rights and water quality policy. As a result, the SWRCB issues NPDES Storm Water permits in the form of Waste Discharge Requirements (WDRs) to Phase I and II permittees in California. More specifically, the SWRCB is the regulating authority for industrial and construction activities, while local RWQCBs issue and enforce MS4 storm water permits. General Industrial Storm Water Permit The General Industrial Storm Water Permit (GISP), WDRs Order 97 -03 -DWQ, NPDES Permit No. CAS000001, regulates storm water discharges from 10 categories of industrial activities. Construction activities are regulated under a separate permit issued by the SWRCB. Industrial facilities that qualify must submit a Notice of Intent (NOI) to file for permit coverage or otherwise be in violation of the CWA. The SARWQCB, under the guidance of the SWRCB, administers and oversees the GISP program within the Santa Ana River Watershed. The proposed project does not have any regulated industrial activities planned for the project site, and, therefore, coverage under the Industrial Permit is not required. General Construction Permit According to the US EPA, a construction site without proper sediment and erosion controls can discharge 10 to 20 times the sediment load of agricultural lands, and 1,000 to 2,000 times the rate from forestlands. The General Construction Permit (GCP) WDRs Order 99 -08 -DWQ, NPDES Permit No. CAS000002, regulates storm water discharges associated with construction activities disturbing one acre or greater of soil. Construction sites that qualify must submit a Notice of Intent (NOI) to file for permit coverage or otherwise be in violation of the CWA. The SWRCB website indicates that the GCP "requires the development and implementation of a Storm Water Pollution Prevention Plan ( SWPPP). The SWPPP should contain a site map(s), which shows the construction site perimeter, existing and proposed buildings, lots, roadways, storm water collection, and discharge points, general topography both before and after construction, and drainage patterns across the project. The SWPPP must list Best Management Practices (BMPs) [that will achieve BCT and BAT performance standards] the discharger will use to protect storm water runoff and the placement of those BMPs. Additionally, the SWPPP must contain a visual monitoring 4.3 -2 Michael Brandman Associates H\Cl t (PN JN)b327b327W3MME 3270030 Sec 3Hyd bUadWat Wity.d
