Storm Water Program: Alphabetic List of SIC Codes

Potentially regulated Standard Industrial Classification (SIC) Codes

The Standard Industrial Classification (SIC) codes listed below are potentially regulated by the Industrial General Permit  based on Attachment A. When evaluating whether a facility is required to obtain coverage under the Industrial General Permit on the basis of its SIC code, please consider any applicable footnote at the bottom of this webpage. In some instances, those footnotes describe situations in which a facility with a commonly-regulated SIC code is not required to obtain Industrial General Permit coverage.   The below list is not a complete list of every type of facility required to obtain Industrial General Permit coverage.

   Refer to Attachment A of the Industrial General Permit for complete descriptions of the types of facilities requiring coverage. Additionally, per Industrial General Permit section XIX and Code of Federal Regulations, title 40, section 122.26(a)(9)(i)(D), a Regional Water Quality Control Board may require a facility to obtain permit coverage even if it is not otherwise required to do so if the Regional Water Quality Control Board determines that the facility’s discharge contributes to a violation of water quality standards or is a significant contributor of pollutants to waters of the United States.

   Refer to the Occupational Safety & Health Administration (OSHA) website for full descriptions of each SIC code.
