MS4 Mailing Addresses

The TCEQ requires all regulated dischargers of storm water to notify the MS4 operator each time permit coverage is obtained as well as terminated. The Municipal Separate Storm Sewer System (MS4) operator is typically just your local authority. However, an MS4 operator can include entities such as the Texas Department of Transportation, Municipal Utility Districts, or other publicly controlled drainage systems. Mailing addresses to many of the MS4 operators in Texas can be found above. We have also provided links to many of the operator's websites in case you need additional information.

The lists above include both regulated and unregulated MS4 operators. Mailing addresses do change and Capitol Environmental, Inc. does not guarantee that the addresses above are accurate. Please contact us if you see that any of the information provided needs to be updated. Thank you.
