Dear Mr. Cassidy:
ROY COOPER
Governor
MICHAEL S. REGAN
secretary
S. DANIEL SMITH
Interim Director
The Division of Energy, Mineral and Land Resources (DEMLR) has reviewed your submittal of the No
Exposure Certification for Exclusion from NPDES Stormwater Permitting form. Based on your submittal and
signed certification of no exposure at the above referenced facility as well as observations made during the
site visit conducted by Mooresville Regional Office staff on May 2, 2019, the Division is granting your
conditional exclusion from permitting as provided for under 40 CFR 122.26(g), which is incorporated by
reference in North Carolina regulations.
Please note that by our acceptance of your No Exposure Certification, you are obligated to maintain no
exposure conditions at your facility. If conditions change such that your facility can no longer qualify for the
No Exposure Certification, you are obligated to immediately obtain NPDES permit coverage for your
stormwater discharge. Otherwise, the discharge becomes subject to enforcement as an un-permitted
discharge. You must self re -certify annually using the enclosed form, or obtain NPDES permit coverage for
any stormwater discharges from your facility. The annual self re -certification does not need to be submitted
to DEMLR unless requested.
Your conditional exclusion from permitting does not affect your facility's legal requirements to obtain
environmental permits that may be required under other federal, state, or local regulations or ordinances.
If you have any questions or need further information, please contact Mr. James Moore at [phone].
Sincerely,
3---�S.
