Dear James Morris:
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
a site visit conducted by Kathryn Peterson with the Mooresville Regional Office on May 29th 2024,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 that the No Exposure conditions are being met by completing .
the Annual Self Re-Certification Form,which can be found at https://deq.nc.gov/about/divisions/energy-
mineral-land-resources/npdes-no-exposure.The completed form does not need to be submitted but shall
be kept onsite and made available upon request.
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 Brittany Cook at(919) 707-3648.
