Construction Stormwater

The NPDES Construction Stormwater Program regulates construction activities that disturb more than one acre under a general permit (NCG010000 or NCG250000, a.k.a. NCG01 or NCG25). Permittees are required to develop and implement an Erosion and Sedimentation Control (E&SC) Plan, adhere to materials handling protocols, inspect their sites and maintain records. The review and approval of E&SC Plans is done by the DEMLR Sediment Program and local governments that have achieved delegation of this program from DEMLR. 
All NCG01 Project Records may be accessed in this section of our Laserfiche Repository.

NCG01 Annual Permit Fees

NCG01 annual permit fees of $100 are scheduled to go into effect on August 1, 2019.  The e-NOI form will be updated to provide clear directions about what you need to do to pay your permit fee.  There will be two options: Use the e-Payment (via credit card or e-check) or mail us a check.  When the fees go into effect, you will not receive your COC until we receive payment.

Updates on the New NCG01 and Draft NCG25

The new NCG01 Permit went into effect on April 1, 2019. Some things to know:
  • Permittees who have an E&SC Plan approved on or after April 1, 2019 are required to submit an electronic Notice of Intent (e-NOI) form (below). 
  • Construction activities shall follow the new NCG01 permit regardless of approval date. 
  • The NCG01 Fact Sheet and The "Dirt" on the New NCG01 presentation will answer many of your questions.

The NCG25 will be issued on August 1, 2019 and is on public notice until June 16, 2019.  This permit is for construction activities on projects that disturb one or more acres and are subject to the federal Clean Water Act but not subject to the NC Sedimentation Pollution Control Act.

e-NOI and e-NOT Forms and Tips for Applicants

After receiving approval of the E&SC Plan, the next step is to fill out and submit an electronic Notice of Intent (e-NOI) form to receive a Certificate of Coverage (COC) under the NCG01 Permit.  WIthin three business days, DEMLR will issue the COC via email to the applicant (if the form is complete and correct).  After the completion of a project, the final step is to submit an electronic Notice of Termination (e-NOT) form to end coverage under the NCG01 Permit.

Sample Plan Sheets and Forms

Below are sample plan sheets that provide guidance on complying with key portions of the NCG01 Permit.  These sample plan sheets provide more detail than is provided in the NCG01 permit.  Permittees are not required to use the sample plan sheets; they convey one way that the objectives set forth in the permit may met.
