• Part I Section A - This part explains that the No Exposure Exclusion from permitting option may be available to the

Your facility is currently covered for stormwater discharge under General Permit NCG070000. This permit expires
on March 31, 2003. The Division staff is currently in the process of rewriting this permit and is scheduled to have
the permit reissued by early spring of 2003- Once the permit is reissued, your facility would be eligible for
continued coverage under the reissued permit.
In order to assure your continued coverage under the general permit, you must apply to the Division of Water
Quality (DWQ) for renewal of your permit coverage. To make this renewal process easier, we are informing you in
advance that your permit coverage will he expiring. Enclosed you will find a Permit Coverage Renewal
Application Form. The application must be completed and returned by October 2, 2002 in order to assure
continued coverage under the general permit. Due to staff and budget constraints, letters confirming our receipt of
the completed application will not be sent.
Failure to request renewal within the time period specified, may result in a civil assessment of at least $250.00.
Larger penalties may be assessed depending on the delinquency of the request. Discharge of stormwater from your
facility without coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1
and could result in assessments of civil penalties of up to $10,000 per day.
Please note that recent federal legislation has extended the "no exposure exclusion" to all operators of industrial
facilities in any of the 11 categories of "storm water discharges associated with industrial activity," (except
construction activities). If you feel your facility can certify a condition of "no exposure", i.e. the facility industrial
materials and operations are not exposed to stormwater, you can apply for the no exposure exclusion. For additional
information contact the Central Office Stormwater Staff member listed below or check the Stormwater & General
Permits Unit Web Site at http://h2o.enr.state.ne.us/su/stormwater.htmi
If the subject stormwater discharge to waters of the state has been terminated, please complete the enclosed
Rescission Request Form. Mailing instructions are listed on the bottom of the form. You will be notified when the
rescission process has been completed.
