No Exposure Certification for Exclusion
NCGNEOOOO
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. Industrial materials or activities include, but are not limited to:
• material handling equipment or activities, • by-products,
• industrial machinery, • final products,or
• raw materials, • waste products.
• intermediate products,
Material handling activities include the storage, loading and unloading, transportation, or conveyance of any raw
material, intermediate product,final product,or waste product.
A storm resistant shelter is not required for industrial materials stored in the following container types, provided
the containers are not deteriorated and do not leak:
• drums, • tanks,and
• barrels, • similar containers.
For new facilities, applicants should apply no earlier than 60 days before the start of operation. This will allow
DEMLR staff to verify conditions during active operation. For facilities that already have an industrial stormwater
permit 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 Until you are issued a No Exposure Certification and your NPDES permit is rescinded,your facility must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.
A No Exposure Certification must be provided for each facility qualifying forthe no exposure exclusion.Additionally,
the exclusion from NPDES permitting is available on a facility-wide basis only— not for individual outfalls. If any
industrial activities or materials are,or will be,exposed to precipitation,the facility is not eligible forthe noexposure
exclusion.By signing and submitting this No Exposure Certification form,you certify that a condition of no exposure
exists at this facility or site and are obligated to comply with the terms and conditions of 40 CFR 122.26(g).
For new facilities,applicants should not apply more than 60 days before the start of operation date.This
If approved,your conditional No Exposure Certification has no expiration date but must be self-recertified at least
annually. Please look for information about recertification under the No Exposure section on this page:
https•//deg nc goy/about/divisions/energy-mineral-land-resources/nodes-no-exposure.
Directions: Print or type all entries on this application form. Send the original, signed application to: NCDEMLR
Stormwater Program, 1612 MSC, Raleigh, NC 27699-1612. The submission of this form does not guarantee
exclusion from NPDES stormwater permitting. Prior to exclusion from NPDES stormwater permitting a site
inspection will be conducted.

` facility or site identified in this document(except as allowed under 40 CFR 122.26(g)(2)).
YJ I understand that I am obligated to maintain no exposure conditions and complete a Self-Recertification form at least
once each year and,if requested,provide this certification to the operator of the local municipal separate storm sewer
system(MS4)into which the facility discharges(where applicable). I understand that I must allow the North Carolina
