Brian R. Smith - 2 - 18 April 2001 Health Services. Prior to any wastewater treatment, storage, or disposal,the Discharger shall submit a Report of Waste Discharge (RWD) at least 120 days prior to discharging wastewater at the site. Because preparation of an NPDES permit requires more extensive engineering studies to be performed as part of the RWD, the NPDES permit process takes longer. Submittal of the RWD is required by California Water Code Section 13260. If groundwater dewatering is required, the owner/operator shall submit a RWD to apply for a National Pollutant Discharge Elimination System(NPDES)permit at least 120 days prior to initiating dewatering activities. Depending on the Standard Industrial Classification(SIC)code of the final project, compliance with the National Pollutant Discharge Elimination System(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 a Storm Water Pollution Prevention Plan (SWPPP) must be prepared. Because construction associated with the project will disturb more than five acres or is part of a larger common plan of development that encompasses five or more acres,the property owner needs to obtain permit coverage under the National Pollutant Discharge Elimination System(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 S WPPP must be prepared. If there are any questions about this process or the storm water program, you may call Dani Berchtold at(916) 255-3383 or Leo Sarmiento at(916) 255-3049. Additional information can be found at the Storm Water website - http://Www.swrcb.ca.govlstormwtrlindex.html. 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. For more information, contact the Sacramento District of the Corps of Engineers at(916) 557-5250 or Matthew Reischman with the Regional Board at (916) 255-3120. If you have any questions about the RWD process, please telephone me at (916) 255-3116. If you have questions on the NPDES permitting process, please telephone Patrica Leary at(916) 255-3023.
