Stormwater & MS4 Areas

About the Stormwater and MS4 Areas

***ATTEND OUR ANNUAL MS4 PUBLIC WORKSHOPS!***

Details will be announced in summer 2022.

Hays County is subject to the requirements of the Texas Commission on Environmental Quality (TCEQ) Texas Pollutant Discharge Elimination System (TPDES) General Permit No. TXR040000, issued January 24, 2019, which sets the requirements and conditions for stormwater discharges from a small Municipal Separate Storm Sewer System (MS4) to surface waters in the state.


The County previously developed and implemented a stormwater management program (SWMP) to comply with the original TPDES Small MS4 General Permit issued in August 2007 since it was located within the San Marcos-Buda-Kyle, Texas Urbanized Area (UA), as defined by the 2000 U.S. Census.
