4. CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD (Staff Contact: Timothy O'Brien, [916) 464-4616) a. CONSTRUCTION STORMWATER PERMIT: A National Pollutant Discharge Elimination (NPDES) General Permit for Storm Water Discharges Associated With Construction Activities, Order No. 99- 28-DWQ, is required when a project involves clearing, grading, or disturbances to the ground such as stockpiling or excavation. Currently, construction activity that involves soil disturbances on construction sites five acres or greater or which part of a larger common plan of development or sale require a construction storm water permit. Because construction associated with the project will disturb more than five acres, the property owner needs to obtain permit coverage under the NPDES General Permit No. CAS000002 for Discharges of Storm Water Associated With Construction Activity. Before construction begins, the proponent must submit an NOI to comply with the permit to the State Water Resources Control Board, and a Stormwater Pollution Prevention Plan (SWPPP) must be prepared. The permitting requirement applies both that the excavation site and the processing facility. b. INDUSTRIAL STORMWATER PERMIT: Depending on the Standard Industrial Classification (SIC) code of the final project, compliance with the NPDES General Permit No. CAS000001 for Discharges of Storm Water Associated With Industrial Activities may be required. The SIC codes of activities requiring coverage are listed in the General Permit In order to obtain coverage by the General Permit, the proponent must submit a Notice of Intent to comply with the permit(NOI)to the State Water Resources Control Board, and an SWPPP must be prepared. The permitting requirement applies both at the excavation site and the processing facility. c. SECTION 404 PERMIT: If the project will involve the discharge of dredged or fill material into navigable waters or wetlands, a permit pursuant to Section 404 of the Clean Water Act may be needed from the US Army Corps of Engineers. If a Section 404 permit is required by the Corps, the Board will review the permit application to ensure that discharge will not violate water quality standards. If the project requires surface water drainage realignment, the applicant is advised to contact the Department of Fish and Game for information on Streambed Alteration Permit Requirements. If a Section 404 permit is required, the proponent must apply to the Regional Board for a Water Quality Certification under Section 401. d. DEWATERING PERMIT: The proponent may be required to file a Dewatering Permit covered under WDR's General order for Dewatering and Other Low Threat Discharges to Surface Water Permit, Order no. 5-00-175 (NPDES CAG995001).
