Mr. Appel:
The Division has reviewed your submittal of the application for No Exposure Certification requesting
exclusion from NPDES stormwater permitting at Machine Consulting Services Inc. Based on your
submittal of a signed certification of no exposure and on inspection by Thad Valentine on January 28,
2021, the Division is Granting the 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, Machine Consulting Services Inc.
is obligated to maintain no exposure conditions at this facility. If conditions change such that the facility no
longer qualifies for no exposure exclusion, you are obligated to immediately obtain NPDES permit
coverage for any stormwater discharge. Otherwise, the discharge becomes subject to enforcement as
unpermitted discharge.
Machine Consulting Services Inc.must recertify the no exposure status annually using the included form.
Any "yes" answer would require that you obtain NPDES permit coverage for stormwater discharge from
the facility. The annual self -recertification form does not need to be submitted to DEMLR, unless
requested. Please note that this 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 Thad Valentine or me at (919) 791-
4220
Sincerely,
Thad Valentine
