Dear Mr.Chatha:
The Division has reviewed your submittal of the No-Exposure Certification for Exclusion from NPDES
Stormwater Permitting form and made a site visit to assess the potential for stormwater pollution. Based on our
observations and your submittal and signed certification of no exposure at the above referenced facility,the
Division is granting your conditional exclusion from permitting as provided for under 40 CFR 126.22(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 as an un-permitted discharge(subject
to civil penalties of up to$25,000 per day). Your conditional no-exposure exclusion does not expire.
However,you must self re-certify annually using the enclosed form,or obtain NPDES permit coverage for
any stormwater discharges from your facility. Please store the completed re-certification forms in order to
have them available during future inspections by DWQ.
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 Dave Parnell at(919) 791-4200 or at
[e-mail].

Dear Mr.Chatha:
The Division has reviewed your submittal of the No-Exposure Certification for Exclusion from NPDES
Stormwater Permitting form and made a site visit to assess the potential for stormwater pollution. Based on our
observations and your submittal and signed certification of no exposure at the above referenced facility,the
Division is granting your conditional exclusion from permitting as provided for under 40 CFR 126.22(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 as an un-permitted discharge(subject
to civil penalties of up to$25,000 per day). Your conditional no-exposure exclusion does not expire.
However,you must self re-certify annually using the enclosed form,or obtain NPDES permit coverage for
any stormwater discharges from your facility. Please store the completed re-certification forms in order to
have them available during future inspections by DWQ.
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 Dave Parnell at(919) 791-4200 or at
[e-mail].
