The Division has reviewed your submittal of the No -Exposure Certification form for Exclusion from NPDES Stormwater
Permitting. Based on your submittal and signed certification of no exposure at the above referenced facility, the site visit of
January 30, 2013, and the follow-up analytical sampling at Outfall 001 (via email dated February 1], 2013), the Division is granting
your conditional exclusion from permitting as provided for under 40 CF'R 122.26(g), which is incorporated by reference in North
Carolina regulations. This conditional exclusion is also based on the facility's continued monitoring of Outfall 001 under the
requirements of the existing NPDES General Wastewater Permit No. NCG500582.
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 inunediately obtain NPDES permit coverage for your stormwater discharge. Otherwise, the discharge becomes subject to
enforcement as an un-permitted discharge.
You must self re -certify your No -Exposure status annually using the included form or obtain NPDES permit coverage for any
stormwater discharges from your facility. The annual self re -certification does not need to be submitted to DWQ unless
requested.
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 Wes Bell at [phone], or at [e-mail].
Sincerely,
for Charles Wakild, P.E.

National Poll_utant_Discharge=Elimination System application for exclusion from;a'StormWakk Permit\base
on NO EXPOSURE: ``'"'r'�=��c>e,a�c=r;C•
Submission of this No Exposure Certification constitutes notification'thbtlyour..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, DWQ 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 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 the following industrial materials and activities: drums, barrels, tanks, and similar containers
that are tightly sealed, provided those containers are not deteriorated and do not leak. `Sealed" means
banded or otherwise secured and with locked or non -operational taps or valves; adequately maintained
vehicles used in material handling; and final products, other than products that would be mobilized in
stormwater discharges (e.g., rock salt),
A No Exposure Certification must be provided for each facility qualifying for the no exposure exclusion. In
addition, 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).
You are reauired to self re-certifv vour No Exposure Exclusion ann
