No Exposure Certification for Exclusion
NCGNE0000
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 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rescinded, your facility must continue to abide by the terms and conditions of the current permit.
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 for the no exposure
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).
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.gov/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.

the condition of no exposure and to make such inspection reports publicly available upon request. I understand I must
keep a copy of annual recertifications on file at the facility.

under an NPDES permit prior to any point source discharge of stormwater from the facility.
