Many of the measures were in place before the (Environmental Protection Agency (EPA) regulations were passed. The EPA has since passed administration of the program on to Texas Commission on Environmental Quality (TCEQ). The State issued the most recent Small MS4 General Permit, Texas Pollutant Discharge Elimination Systems (TPDES) Permit Number TXR040000 on January 24, 2019. View the Small MS4 General Permit (PDF). It authorizes the discharge of stormwater to surface water in the state from small municipal separate storm sewer systems (MS4s). Denton County has 180 days to submit its Stormwater Management Program (SWMP) permit application to TCEQ. View submitted SWMP (PDF). Every year for the duration of the permit Denton County is required to submit an annual report to TCEQ stating how the stormwater management program is being followed. View the Annual Report (PDF).
Each year Denton County moves forward with implementing more components of the program than were in place beforehand. To help guide Denton County in its stormwater management program the County participates in many programs with the North Central Texas Council of Governments. The North Central Texas Council of Governments (NCTCOG) is able to approach Storm Water issues on a more regional scale and brings together people from different organizations to share ideas.
