What is the TPDES Stormwater Multi-Sector General Permit (TXR050000)?

There are a variety of industrial businesses in Texas. In order to protect surface water in the state, the discharge of stormwater leaving these sites requires a permit. In some cases, the discharge is also monitored for contaminants. The multi-sector general permit is one way to authorize this activity.

How can I access a copy of the permit?

You can access the Multi-Sector General Permit, TXR050000 Adobe Acrobat PDF Document online.

Important Note: Be sure you are viewing the current version of the permit with an effective date of August 14, 2016. If the first page shows August 14, 2011, try one of the following:

  • If using Internet Explorer, close the document and return to the internet browser window. Press both Control and F5 on your keyboard, then try opening the document again.
  • Visit the webpage by using a different internet browser such as Google Chrome or Firefox.

Do I need to obtain stormwater coverage at my industrial facility?

If you discharge stormwater associated with an industrial activity* into surface water in the state, you may need authorization. If you are not otherwise prohibited, you may obtain coverage under the MSGP permit if:

  • your Standard Industrial Classification (SIC) code is listed in the permit, or
  • your facility conducts an activity described by one or more Industrial Activity Codes described in the permit, or
  • your facility is subject to federal categorical effluent limitations, or
  • your facility has been designated by the Executive Director as requiring coverage.

We have developed a list of SIC Codes and Industrial Activity Codes Subject to TPDES Multi-Sector General Permit Adobe Acrobat PDF Document to help you determine applicability. If you need to look up the SIC code for your facility, please visit the U.S. Occupational Health and Safety Administration's SIC Search Exit the TCEQ or SIC Manual Exit the TCEQ web page.

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.
