All new and existing point source industrial stormwater discharges associated with industrial activity require an NPDES Stormwater Permit from the Tennessee Division of Water Resources. Most common is a general permit which is available to almost any industry, but there is also an option
A general permit is not available for stormwater that meets any of the following characteristics:
1) is regulated by an individual NPDES permit
2) receives combined treatment with non-stormwater
3) is subject to EPA effluent limitations
4) is subject to another general permit
5) contributes to a violation of water quality standards
6) is discharged from inactive mining, inactive landfills or inactive oil and gas operations occuring on federal lands where an operator cannot be identified
7) is discharged from mining operations with the exception of inactive coal mines and related facilities, construction sand and gravel mining, dimension stone mining and quarrying.
Industries that have no exposure of industrial materials and activities to stormwater can submit a no exposure certification in lieu of an NPDES permit. For information regarding stormwater discharges associated with stream alterations and construction activities, contact the Division of Water Resources.
A completed Notice of Intent (NOI) for the Tennessee Stormwater Multi-Sector General Permit (TSMP) to Discharge Stormwater Associated with Industrial Activity must be submitted at least five (5) days prior to beginning industrial activity at the site. The NOI form requires information regarding the operator/owner, facility, site location and size, industrial activity, material handling, discharging points and water receiving the discharges, existing permits, and other information.
Facilities with no stormwater exposure must submit a no exposure certification form.

The facility will be considered legally covered by the general permit five (5) days after the postmark of the NOI, unless notified otherwise by the Division. No public participation is involved; however, the general permit does allow anyone to file a petition with the Division asking that general coverage be revoked and an individual permit be required. The TSMP is effective through May 14, 2014.
Annual maintenance fees for the Industrial Storm Water General Permit became applicable on January 31, 2001. Fees range from zero for the sites less than or equal to 1 acre to $970 for sites greater than or equal to 500 acres. Permittees will be invoiced by the Division once the NOI has been processed. The fees are given in 0400-40-11 here.
The applicant may proceed with the industrial activity five (5) days after the postmark of the NOI and must comply with all conditions stated on the general permit. Any planned changes or additions to the facility require the discharger to give notice to the Division as soon as possible. A new NOI from the new owner must be submitted at least five (5) days before the facility is sold or transferred.
Applicants must develop a stormwater pollution prevention plan prior to submitting an NOI. Certain categories of industries must conduct annual analytical monitoring of stormwater discharges, with storm water monitoring reports due March 31 of the following calendar year. Almost all permittees must conduct quarterly visual examinations of stormwater discharges throughout the term of the permit.
The Division has the responsibility to take all prudent steps to secure, protect and preserve the waters of Tennessee. The Division and the EPA have the right to enter and inspect the facility and all related records at any reasonable time. They also may inspect any related equipment or monitoring methods. The Division has the right to require an individual permit at any time if deemed necessary.
