The Division has reviewed your submittal of the application for No Exposure Certification
requesting exclusion from NPDES stormwater permitting at Humacyte, Inc. Based on your
submittal of a signed certification of no exposure and on inspection by Thad Valentine on June
15. 2018 the Division is granting 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, Humacyte, 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.
Humacyte, 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
[phone].

STORMWATER PERMITTING
National Pollutant Discharge Elimination System application for exclusion from a Stormwater Permit based
on NO EXPOSURE:
Submission of this No Exposure Certification constitutes notification that your facility does not require a
permit for stormwater discharges associated with industrial activity in the State of North Carolina because
it qualifies for a no exposure exclusion. A condition of no exposure at an industrial. facility means all
industrial materials and,activities are protected by a storm resistant shelter (with some exceptions) to
prevent exposure to rain, snow, snowmelt, and/or runoff.
For permitted facilities in North Carolina, DEMLR must approve your application for No
Exposure Certification before this exclusion is effective. Until you are issued a No
Exposure Certification and your NPDES permit is rescinded, your facility must continue
to abide by the terms and conditions of the current permit.
Industrial materials or activities include, but are not limited to: material handling equipment or activities,
industrial machinery, raw materials, intermediate products, by-products, final products, or waste products.
Material handlino activities include the storage, loading and unloading, transportation, or conveyance of
any raw in I -inal product or waste product. A storm resistant shelter is not
required AI /� IQC� � Yials and activities: drums, barrels, tanks, and similar containers
that are tit n ` i )ntainers are ^ter+ tin not leak. "Sealed" means
banded of I " /, _ )eked or nor �� I�� 23 , lequately maintained
