General Permit TXR040000 for Phase II (Small) MS4s

Requirements for obtaining authorization for stormwater discharges from small MS4s, the new General Permit, forms and annual reporting.

Renewed General Permit for Small MS4s

The new Small MS4 General Permit, TPDES Permit No. TXR040000, was issued on December 13, 2013. It authorizes the discharge of stormwater to surface water in the state from small municipal separate storm sewer systems (MS4s).

The deadline to apply for coverage or a waiver under the General Permit was June 11, 2014. Each regulated entity should have submitted a Notice of Intent (NOI) and a new or revised (for existing regulated entities) Stormwater Management Program (SWMP) or a waiver if applicable.

Find revised forms for applying for coverage or a waiver under the re-issued permit below.

NOI and Waiver forms with effective dates prior to 12/13/2013 are no longer valid.

For specific information on the permit requirements, please refer to the following documents:

For additional information see the Assistance Tools for Stormwater Permitting page or the Q&A document on the new general permit.

If you would like to follow the process of renewing this permit, please access historical information at the Stormwater Stakeholders Group (SWSG) webpage.

Did you receive a notification letter?

Notification letters were mailed on Dec. 11, 2013 to new and existing MS4 entities. TCEQ identified many new MS4s through various sources, however; we might not have been able to identify all of them. If you did not receive a notification letter, you must still apply.

Strengthening the protective elements of your permit

TCEQ utilized the U.S. EPA MS4 Permit Improvement Guide Adobe Acrobat PDF DocumentExit the TCEQ(adopted April 14, 2010) during the permit renewal process and includes specific recommendations from this guide in your permit.

Annual Reports

The 2007 Phase II Small MS4 general permit was in effect until the new general permit was issued. All existing regulated MS4 entities were required to submit an annual report for the 2012-2013 reporting period to comply with the requirements of the 2007 general permit. These reports were due to be submitted to the TCEQ by November 12, 2013.

The deadline or the reporting month for submitting annual reports for the renewed general permit is based on the reporting period selected in the NOI submitted to TCEQ to obtain permit coverage.

For the transitional period between the expired and the new general permit, existing MS4 entities should have reported the activities conducted during the four months from August 12 to December 11, 2013 along with their Year 1 annual report submitted under the new general permit. A separate annual report covering only this four month period was not required.
