Stormwater discharges associated with industrial activity are required to be covered under an NPDES permit. You can view a description of Stormwater discharges associated with Industrial Activities to see if your facility requires a permit. The Department may also designate other facilities as requiring a permit, particularly where there is a potential for stormwater contamination.
The Industrial Stormwater General Permit
Many facilities are eligible for coverage under the general permit (PDF). The current general permit is applicable through September, 2021.
Notice of Intent (NOI)
If your facility requires an industrial stormwater permit, you will need to complete and submit a Notice of Intent form (DHEC Form 2611).
In accordance with regulations and NoI instructions , signatures on the NOI must be from an officer of the corporation, a proprietor, or appropriate government official (as pertinent) or the plant manager.
No Exposure Exemption
If industrial materials or activities are not exposed to stormwater, an exemption from the permit can be requested. This "no exposure" exclusion does not apply to construction activities.

The condition of no exposure must be maintained by keeping all industrial materials or activities protected at all times. If "no exposure" conditions are not maintained, the operator must immediately apply for an NPDES stormwater permit as noted above. The no exposure exemption is good for five years.
Completion and submittal of a Notice of Termination (NOT) is required when any of the following occurs:
- The property is sold
- Activities are no longer present that would require a stormwater NPDES permit.
Standard Industrial Classification
The SIC code system is maintained by the US Department of Labor, Occupational Safety & Health Administration (OSHA) and is available for searching at www.osha.gov/oshstats/sicser.html.
Construction activities associated with industrial stormwater are covered under a separate permit and do not require an industrial stormwater permit. Once construction is completed, a facility which is an industrial activity (except construction) would require additional coverage under the industrial stormwater general NPDES permit.
There is an annual fee of $75 for coverage under the general permit. The fee must accompany the NOI. Fees are based on the fiscal year of July 1st through June 30th. There is no prorating of the fee for coverage for a portion of the year. The annual fee is billed about the middle of August each year, for continuing coverage.
Coverage under the general permit is automatically granted nine days after the postmark of the NOI unless the Department notifies the applicant differently. The Department has the authority to request the submission of the SWPPP for review and approval before granting general permit coverage, or at other times . Alternately, the Department has the authority to require an individual permit application be submitted for issuance of an individual permit in lieu of granting general permit coverage.
No Exposure Certification
There is a $350.00 fee due with the no exposure certification form. Once approved, no exposure certification is good for five years. At that time, resubmittal of the form and fee will be required.
