Presentation on theme: "What is NPDES? “National Pollutant Discharge Elimination System”"— Presentation transcript:
1What is NPDES? “National Pollutant Discharge Elimination System” The Clean Water Act prohibits anybody from discharging "pollutants" through a "point source" into a "water of the United States" unless they have an NPDES permit. The permit will contain limits on what you can discharge, monitoring and reporting requirements, and other provisions to ensure that the discharge does not hurt water quality or people's health. In essence, the permit translates general requirements of the Clean Water Act into specific provisions tailored to the operations of each person discharging pollutants.
2NPDES Backround 1972 Clean Water Act 1987 Administered by the US Environmental Protection Agency (EPA)Created NPDES permitting processMultiple amendments1987An amendment to CWA called Water Quality Act required EPA to develop phased program to regulate storm water discharges under NPDES program.
3NPDES Storm Water Program Point Source PollutionDischarges from readily identifiable sources such as wastewater treatment plants or industrial facilitiesNon-point Source PollutionDischarges that are less easily identifiable such as runoff from urbanized or agricultural areas
4NPDES in South Carolina South Carolina is an NPDES delegated state.NPDES regulations are administered by South Carolina Department of Health and Environmental Control (DHEC).Construction General Permit (CGP) is a component of NPDES.
5NPDES Phase II Construction General Permit Issued February of 2005; appealedAppealed settled in late 2005New Phase II CGP became effective on September 1, 2006Existing or ongoing permitted projects will be grandfathered under old regulations and not have to meet Phase II CGP requirements
6Who must obtain NPDES permit coverage? All land disturbing activities greater than or equal to 1 acre.Any disturbance within ½ mile of a receiving water body in the S.C. Coastal Zone (except individual single family homes not part of a subdivision development.)
7Requirements of CGPDevelop and implement Storm Water Pollution Prevention Plan (SWPPP)Identification of operators to be working onsiteSequence of constructionLocations of all BMPs necessary to minimize pollutants in stormwater discharges to meet applicable water quality standards.Locations of Surface Waters of the StateMust be in compliance with all other applicable permits or CGP is invalid.
8Requirements of CGPMust comply with Federal reporting requirements related to spills or releases or oils or other hazardous substances.File Notice of Termination (NOT) when construction is completeRetain all documentation required by permit for three years from time permit is terminated.
10What’s Coming Small Municipal Separated Storm Sewer System (MSS4) -Unfunded Mandate from EPA to DHEC to Local Government-Six Elements of Program--Public Education--Public Involvement--Illicit Discharge--Construction Activities--Post ConstructionMunicipal Activities

14Construction Site Runoff WhyIt’s the Law of the LandSite Runoff Carries Sediment and PollutionIncreasing Volume of Runoff Increases FloodingHowBest Management Practices Requirements
15Post-Construction Runoff Control WhyUntreated Runoff Contains Oil/Greases, Heavy Metals, Pesticides, Fertilizers and Pet WasteHowMaintaining BMPs from Construction PhaseRetrofitting BMPs that are not WorkingNon-Structural BMPs (Education, Pet Waste Pickup, Proper Use of Fertilizer and Pesticides)
