Submitting a Notice of Intent (NOI), Notice of Termination (NOT), or Low Erosivity Waiver (LEW) under the Construction General Permit

Submit your NOI, NOT or LEW through the electronic CGP submission system, the NPDES eReporting Tool or “CGP-NeT”.

Go to CGP-Net to submit your NOI, NOT, or LEW.

How to Modify and Terminate Permit Coverage

Modifying your NOI

Use the CGP-NeT system to modify your NOI. The following modifications to an NOI form will result in a 14-day review process:

• Name of the operator
• Project or site name
• Estimated area to be disturbed
• Name of the receiving water or additions to the applicable receiving waters
• Endangered Species Protection or Historic Preservation eligibility information
• Information provided on the use of Chemical Treatment at your site
• Answers provided regarding the demolition of structures over 10,000 square feet of floor space built or renovated before January 1, 1980

During the 14-day review process, you may continue to operate based on the information provided in your original NOI, but you must wait until the review period has ended before you can commence or continue activities on any portion of your site that would be affected by any of the above modifications, unless EPA notifies you that the authorization is delayed or denied.

Terminating Coverage

Use the CGP-NeT system to submit a Notice of Termination (NOT) to terminate your permit coverage. You can submit an NOT once your site is permanently stabilized or when control of the site has been transferred to another operator.
