We have finished the process of renewing this general permit, which expired August 12, 2012. A notice of intent to renew the general permit was published in the Texas Register on April 13, 2012, to allow administrative continuance of coverage to regulated Phase II MS4 entities under the 2007 MS4 general permit.

hot_tiny.gifThe new Small MS4 General Permit, TPDES Permit No. TXR040000, was issued on December 13, 2013. All regulated entities (new and existing) will have 180 days to apply for coverage or a waiver under the general permit, the deadline to apply is June 11, 2014. Each regulated entity must submit a Notice of Intent (NOI) and a new or revised (for existing regulated entities) Stormwater Management Program (SWMP) or a waiver if applicable.

Revised forms for applying for coverage or a waiver under the re-issued permit are now available.

Please note that the previous NOI and Waiver forms are no longer valid.

hot_tiny.gif 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. Please note that, it is still the responsibility of the MS4 to apply even though it might not have received a notification letter.

EPA MS4 Permit Improvement Guide

On April 14, 2010, the U.S. EPA adopted the MS4 Permit Improvement GuideAdobe Acrobat PDF DocumentExit the TCEQ The primary purpose of this guidance document is to assist permit writers at EPA and the states in strengthening Phase I and Phase II MS4 permits.

During the renewal of each individual Phase I permit, as well as during the Phase II general permit (TXR040000), the TCEQ reviewed this document to determine the extent to which the recommendations in this document could be incorporated into the TPDES MS4 permits.

Phase I: Individual MS4 permits are processed for renewal as they are received, with most applications submitted in late 2010 and 2011. Renewed Phase I MS4 permits include additional minimum control measures from the Phase II regulations where appropriate. For specific questions on your permit conditions, please contact the Stormwater and Pretreatment Team.

Phase II: The TPDES general permit for small MS4s expires on August 13, 2012, and the TCEQ will reissue the permit later than the expiration date. TCEQ reviewed the guidance document during the renewal process to determine the extent to include specific recommendations from this guide.

hot_tiny.gifAnnual Reports

Annual Report Template

The 2007 Phase II Small MS4 general permit was administratively continued until the issuance of the new general permit. Therefore, all existing regulated MS4 entities were still required to submit an annual report for the 2012-2013 reporting period in order to continue to comply with the reporting requirements of the 2007 general permit. These annual report were due to be submitted to the TCEQ by November 12, 2013.

When should existing MS4 entities report activities conducted during the August 12 - December 11, 2013 reporting period?

  • For the transitional period between the expired and the new general permit, existing MS4 entities can report the activities conducted during the four month period 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 is not required but this period should be included with the Year 1 annual report.
