The Stormwater Permitting Program develops, plans and implements statewide stormwater control policies, strategies and rules designed to protect surface waters of North Carolina from the impacts of stormwater pollutants and runoff. Staff handles permitting for industrial, municipal and post-construction (development projects) stormwater programs, and provides technical assistance to the regulated community, engineers, industry, citizens and local governments.

NPDES Stormwater Program
The National Pollutant Discharge Elimination System stormwater permitting program regulates three types of activities: Industrial activities that fall in one of 10 categories; Municipal Separate Storm Sewer Systems (MS4s); and construction activities that disturb an acre or more.
The National Pollutant Discharge Elimination System (NPDES) Electronic Reporting Rule became effective December 21, 2015. According to the rule, starting on December 21, 2016, regulated entities that currently submit DMRs to NC DWR (including DEMLR Stormwater Program permittees) should begin submitting these reports electronically, instead of on paper. The capability for NPDES Stormwater Permit-holders to submit data through NC's eDMR System is not yet in place; however, DEQ is working towards this goal and will contact permittees with updates. DEQ's system will not be ready by December 21, 2016. More information about the rule and e-Reporting requirements can be found in this brochure or on our website about how e-Reporting will affect DEMLR's Stormwater Program.
State Stormwater Programs
The State Stormwater Permitting Programs regulates site development and post-construction stormwater runoff control. Areas subject to these permit programs include all 20 coastal counties and various other counties and watersheds throughout the state. Areas subject can be found using the Interactive Stormwater Permitting Map.
