Dear Douglas Haines:
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 inspector with the Raleigh Regional Office
on March 31st 2023,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.
