The City of Coppell's Stormwater Management Program is committed to educate the public, contractors and developers on the storm water system and regulations, while promoting environmental stewardship. As a vital element in the City of Coppell overall water resource management strategy, our mission is to efficiently implement a stormwater program that effectively addresses flood control and run-off quality issues while emphasizing the elimination of non-point pollution at the source.
Stormwater discharges are generated by runoff from land and impervious areas during rainfall. Surfaces like driveways, sidewalks, and streets prevent stormwater from naturally soaking into the ground.
Stormwater can carry litter, sand, bacteria, oil and other chemicals as it flows to our streams, rivers, ponds and wetlands. Runoff from paved surfaces may contribute large amounts of polluted storm water. Cleaning up stormwater not only benefits our neighborhoods and town, it also benefits the entire network of water bodies and land that make up our watershed.
In City of Coppell, stormwater quality is regulated at the federal level by the Environmental Protection Agency (EPA), the state level by the Texas Commission on Environmental Quality (TCEQ) and at the local level by the City of Coppell Environmental Health Division.
As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Point sources are discrete conveyances such as pipes or man-made ditches. Individual homes do not need an NPDES permit; however, some industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters.
In 1987, Congress amended the Clean Water Act to require a comprehensive nationwide program for addressing polluted storm water. The National Pollutant Discharge Elimination System (NPDES) is the resulting program. The state assumed the authority to administer the NPDES program in Texas and the Texas Pollution Discharge Elimination System (TPDES) is the resulting program.
The City of Coppell has to develop, implement, and enforce a Stormwater Management Program (SWMP). The goals of the Plan are to:
Per the TCEQ, TPDES General Permit Number TXR040000, the Stormwater Management Plan (SWMP) must provide a listing and description of best management practices (BMP's) developed to prevent stormwater pollution to the maximum extent practicable. BMP's are required to be developed to satisfy five stormwater quality minimum control measures:
