Construction Stormwater

Renewal of the N.C. General Permit for Construction Activities

The N.C. Stormwater Program is renewing and updating the Current NCG01 Permit this spring and summer. 

The technical requirements for construction activities in this New Draft NCG01 Permit have not changed from the current permit, except for minor updates to references and clarification of permit language known to cause confusion for North Carolina stakeholders.  However, there are two significant changes to note:

  • The technical requirements have undergone a major reorganization to increase clarity and understanding for our permittees and the public.  Many of the permit requirements have been organized into tables as a preferred alternative to the lengthy paragraphs that characterize the current version of the permit.
  • The permitting process for the NCG010000 has been updated and improved to require permittees to complete an on-line Notice of Intent form, which will result in a project-specific issuance of a Certificate of Coverage to the permittee for each individual project.

Stakeholder meeting were held on April 9 and April 23 in the Archdale Building's Ground Floor Hearing Room.  We have developed a Slide Presentation on the New Draft NCG01 summarizing the updates.

The New Draft NCG01 Permit is currently being reviewed by the EPA.  We are accepting comments from the public on this draft until July 16, 2018.  If you have suggestions, please submit them to Annette Lucas.

The planned schedule for the renewal process is:

  • By June 15, 2018   The draft permit will be published in the NC Register
  • By June 16, 2018   The notice of the permit renewal will be published
  • Late June 2018       Another stakeholder meeting will be held to receive input on the proposed new permitting process and Erosion and Sediment Control Design Manual.
  • By July 31, 2018    The new permit will be issued

Program Background

All development projects in North Carolina that disturb an acre or more of land require an Erosion and Sedimentation Control (E&SC) Plan that has been approved by either the state or a local government with delegated authority. Once the plan is approved, the project has automatically been covered under a NPDES Stormwater General Permit NCG010000 for construction-related activities, provided that the ground stabilization and basin design requirements in the stormwater permit are included in the erosion and sediment control plan.  The previous construction stormwater permit was issued in 2011. The reissued permit continues to reference the former division and department names as it was technically reissued with no changes. Please note that the permit is now administered by the Division of Energy, Mineral and Land Resources. Any contact associated with the permit should be directed to the division’s regional office or central office staff.The state reissued the NCG01 construction stormwater NPDS permit effective Aug. 1, 2016. The permit was reissued with no changes from the previous permit and will remain in effect through July 2018. All construction projects previously covered by this permit will continue to have permit coverage and no further action is required of the permittee. Previously permitted projects must continue to abide by conditions of the permit until the construction project is complete.
