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

The $100 annual permit fee for the NPDES NCG01 Permit began on August 1, 2019.  The process for receiving a Certificates of Coverage is:
  • The applicant submits the eNOI without payment (just like before).
  • DEMLR staff reviews the eNOI within three business days of submittal. 
  • If the eNOI is determined to be complete, the applicant receives an email with instructions for each of three payment options (credit card, e-check and paper check).  
  • The applicant makes the payment using one of the payment options.
  • Within 24-48 business hours of DEMLR receiving the payment, the applicant receives an email with the COC attached.
  • If payment is not received within 30 days of the email request, then the application will be terminated.

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 October 1, 2019 and was on public notice from May 15 - 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, e-NOT, and Modification Form

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.

Make sure to double-check the e-NOI before you hit "submit."  Common places for errors are the lat/long, waterbody name and index number, and the various dates.  If your e-NOI is incomplete or has mistakes, you will have to submit a new one.  See our contact information below if you have questions.  IMPORTANT:  The on-line forms below will be down Friday, November 8th during a system upgrade.  The system will be back up by Monday, November 11th.   

  • e-NOI form (live as of April 2, 2019The eNOI will not be accessible Friday, Nov. 8th during a system upgrade. 
  • e-NOI form directions
  • e-NOT form (live as of May 22, 2019
  • Modification form (Use this link to add updated E&SC Plan approval and close-out letters to the file for projects that already have an approved COC.)

Single Family Lots and Outparcels

COCs may be issued on a “per contiguous project, per owner” basis - this may be convenient for a builder who is taking down multiple lots in a subdivision or for a campus that is often starting and completing construction projects. See Options for Covering Lots/Outparcels under the NCG01 for guidance on how to cover multiple construction activities within a contiguous project under the NCG01 permit. 

Sample Plan Sheets

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.
