Dear Ms. Gihring,
The Division has reviewed your submittal of the No -Exposure Certification form for Exclusion
from NPDES Stormwater Permitting. Based on your submittal and signed certification of no exposure at the
above referenced facility, and the inspection dated May 30, 2018, 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 a No -
Exposure exclusion, you are obligated to immediately obtain NPDES permit coverage for your stormwater
discharge. Otherwise, the discharge becomes subject to enforcement asanunpermitted discharge.
You must self re -certify your No -Exposure status annually and the form can be downloaded by visiting:
http•//portal ncdenr.or web/lr/npdes-storrnwater the web page for the Division of Energy, Mineral and Land
Resources Stormwater Program. The annual self re -certification does not need to be submitted to DEMLR
unless requested. A copy should be maintained in your file.
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.
