NPDES Stormwater General Permits

North Carolina has 21 different Industrial General Permits that cover stormwater discharges associated with industrial activities and construction.  Industries that are eligible for one of the General Permits are issued a Certificate of Coverage (COC). Each facility's COC contains the same requirements as for all other facilities covered under the same General Permit, but the COC will include the unique site location and receiving water for that facility.

Industrial General Permits are issued for five years. At the end of each five-year cycle, the NC Stormwater Program proposes revisions to the Industrial General Permit, public notices these changes for for 30 days, and contacts permittees to inform them of the proposed General Permit updates. Based on public comments, the Stormwater Program finalizes and issues the General Permit and renews the COCs for all of the covered industrial facilities that are up to date on their permit fees.   

Click on the applicable General Permit number below to open a menu that contains the General Permit text, the Notice of Intent (NOI), data monitoring forms (DMRs), and other documents.  The "Print Package" contains all materials in a single document.  Note that there may be small differences between the monitoring forms within the Print Packages and the monitoring forms that are a separate link, but either is acceptable to use.
