NPDES MS4 Program Sign up for the NPDES Industrial Stormwater Email List The National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) Program is mandated under the federal Clean Water Act. An NPDES MS4 permit is required for every MS4 owner or operator that with jurisdiction in a U.S. Census Bureau designated Urbanized Area. It also applies to entities that are designated under state rules [15A NCAC 02H .0151]. MS4 News & Current Events MS4 annual reporting time is rapidly approaching! The 2021 annual reporting period is July 1, 2020 to June 30, 2021. See the Annual Self-Assessment page for more details. MS4 permit files are available on the Stormwater Program Laserfiche Repository. See the November 2, 2020 MS4 Program Update presentation for the current status of MS4 compliance and to learn what will be new in 2021. Some MS4 communities are submitting Stormwater Management Plans (SWMPs) well in advance of their audits. The Audit Process page provides guidance for permittees who wish to submit SWMPs early. Additional entities will likely be designated for coverage under a NPDES MS4 permit after the 2020 Census data has been processed. DEQ expects to receive data in 2021 and publish designations in 2022.
