Notice of Intent (NOI) form requesting a Certificate of Coverage (COC) under the NCGO10000
Construction Stormwater General Permit. This form MUST be submitted prior to the commencement
of any land disturbing activity on the above named project. The NOI form may be accessed at
deq.nc.gov/NCGO1. Please direct questions about the NOI form to Annette Lucas at

correct NOI Form, a COC will be emailed to you within three business days. Initially, DEMLR will
not charge a fee for coverage under the NCGO1 permit. However, on or after May 1, 2019, a $100 fee
will be charged annually. This fee is to be sent to the DEMLR Stormwater Central Office staff in

the erosion and sedimentation control plan is inadequate to meet the requirements of the Sedimentation

require revisions to the plan and implementation of the revisions to ensure compliance with the Act.
Acceptance and approval of this plan is conditioned upon your compliance with Federal and State
water quality laws, regulations, and rules. In addition, local city or county ordinances or rules may
also apply to this land -disturbing activity. This approval does not supersede any other permit or

there is any change in the information included on the form. In addition, it would be helpful if you
