activity. The eNOI form may be accessed at deq.nc.gov/NCG01. Please direct
questions about the eNOI form to the Stormwater Program staff in the Raleigh central

Title 15A NCAC 4B .0118(a) and the NCG01 permit require that the following

2. The NCG01 permit and the COC, once it is received.
3. Records of inspections made during the previous 12 months.
Also, this letter gives the notice required by G.S. 113A-61.1(a) of our right of periodic

51 through 66), this office may 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 approval.
Please note that this approval is based in part on the accuracy of the information
provided in the Financial Responsibility Form, which you provided. You are
requested to file an amended form if there is any change in the information included
on the form. In addition, it would be helpful if you notify this office of the proposed
starting date for this project.
Your cooperation is appreciated.

Fact Sheet on the New NCG01 Permit
April 2019
ew.•,�mi a m..os.rnui a.s�
The NC Construction General Permit(also known as"NCG01")was renewed on April 1, 2019.The updated permit
does not significantly change the measures that are required to be implemented on construction sites. However,
there are some organizational and technical updates to the permit as described below. Most notably, there is a new
process in which construction sites will obtain official coverage under an NCG01 permit through an electronic
process. DEMLR worked with a broad team of stakeholders to make all of these updates. If you have questions,
contact Annette Lucas at [e-mail] or [phone].
