Stormwater Management Program (SWMP)

Stormwater Management Program

The City of Hutto developed a Stormwater Management Program (SWMP) as required by the Texas Pollutant Discharge Elimination System (TPDES) Small Municipal Separate Storm Sewer system (MS4) General Permit TXR040000.  The Texas Commission on Environmental Quality (TCEQ) issues the permit and inspects the city’s SWMP.

The SWMP is a comprehensive program with the goal of reducing the discharge of pollutants from the city’s storm sewer system; to protect surface water quality; and to satisfy the water quality requirements of the Clean Water Act and the Texas Water Code.  

The SWMP includes five Minimum Control Measures (MCMs) to be developed and implemented to reduce the discharge of pollutants and to protect surface water quality.  Under each MCM, best management practices with measurable goals and an implementation schedule are required to be implemented.    

MCM 1: Public Education, Outreach, and Involvement

MCM 2: Illicit Discharge Detection and Elimination (IDDE)

MCM 3: Construction Site Stormwater Runoff Control

MCM 4: Post Construction Stormwater Management

MCM 5: Pollution Prevention and Good Housekeeping for Municipal Operations

The City of Hutto submits an annual report to the TCEQ as required by the MS4 general permit.  The Annual Report describes the progress the city is making in implementing the BMPs for each of the MCMs.
