Stormwater Discharges from Industrial Facilities: Am I Regulated?

Identifies sectors of industry that may obtain coverage under the industrial stormwater general permit for stormwater runoff. The general permit includes coverage for stormwater runoff from manufacturing, processing, material storage, and waste material disposal areas.

The TCEQ has Renewed the General Permit for Industrial Facilities

The 2021 Multi-Sector General Permit (MSGP, TXR050000) for industrial facilities was renewed and issued with an effective date of August 14, 2021.

Am I Regulated?

If you discharge stormwater associated with an industrial activity into one of the following:

And your business activity fits into one of the regulated industrial sectors, meaning that your industrial activity fits under one or more of the Standard Industrial Classification (SIC) Codes or Industrial Activity Codes to be found in " SIC Codes Subject to TPDES Multi-Sector General Permit Adobe Acrobat PDF Document" (Help with PDF.)

Then you will be required to obtain coverage under the MSGP, TXR050000 Adobe Acrobat PDF Document.

      • If all industrial activities and materials are isolated from rain, snow, snowmelt, and/or runoff by storm resistant shelters, you may be eligible for a conditional no exposure exclusion from permitting requirements.

      • Otherwise, the general permit requires you to obtain coverage, which includes submitting a notice of intent (NOI) form.

If you only have a North American Industrial Classification System (NAICS) code and do not know the SIC code that describes your industrial activity, then it will be necessary to determine if coverage under this permit applies to your facility. Refer to Part II of the general permit to determine the appropriate conversion.

If you don't qualify for coverage under this general permit, you may need to obtain an individual permit for any discharges to water in the state.

If you conduct an activity related to oil and gas, you may need to obtain coverage under the U.S. Environmental Protection Agency's (EPA's) Stormwater Discharges Associated with Industrial Activities until TCEQ’s MSGP is amended to include coverage for oil and gas activities.
