Our Programs

Stormwater Permit Compliance

Stormwater management programs required by the Texas Pollutant Discharge Elimination System (TPDES) permit include, among other things, the implementation and maintenance of structural and non-structural BMP to reduce pollutants in stormwater runoff from residential, commercial, and industrial areas, including construction sites. The TPDES permit program requires each Joint Task Force (JTF) member to:

  1. Effectively prohibit illegal dumping and disposal of hazardous chemicals
  2. Monitor and analyze stormwater
  3. Promote the proper management of pesticides, herbicides, and fertilizers.

The Flood Control District is required to comply with the requirements of the following individual and general permits:

  • Municipal Separate Storm Sewer System Permit (MS4): The Flood Control District’s Phase I MS4 permit was originally issued in 1998 with a five-year permit term. Through the implementation of the Stormwater Management Program (SWMP), the District incorporates activities to prevent or reduce the discharge of pollutants into surface waters of the state of Texas.
  • Construction General Permit (CGP): In compliance with this permit, the Flood Control District develops a Stormwater Pollution Prevention Plan (SWPPP) for its construction projects to better manage erosion and construction site runoff through the use of construction BMPs.
  • Pesticide General Permit (PGP): The Flood Control District is permitted under the PGP for all pesticide applications into, over, or near our waterways and other drainage channels. By implementing a Pesticide Discharge Management Plan (PDMP), the Flood Control District minimizes pesticide discharges, thereby protecting local waterways.
  • Multi-Sector General Permit (MSGP): The Flood Control District tracks compliance with this permit by ensuring that industrial applicants for discharge to Flood Control District rights of way have proper stormwater and wastewater pollution safeguards in place. For information on tracking compliance with this permit, as described above, visit the Texas Commission on Environmental Quality’s MSGP website.
