The National Pollutant Discharge Elimination System (NPDES) is program authorized by Clean Water Act (CWA) to protect the surface waters of the U.S. making them safe for drinking, fishing, swimming, and other activities. This program regulates the discharges of pollutants of point sources since 1972. Point sources are those identifiable and localize sources or point of discharge such as pipes, canals, and ditches. Nonpoint Source Management Program became part of the TPDES program in 1989 when it was established in section 319 as part of the CWA. Nonpoint sources are diffuse sources which are difficult to identify and manage and that have a negative impact in the receiving water body.
Perfect examples of nonpoint source pollution are agrictultural runoff polluted with fertilizer,
pesticide, and other contaminants as well as urban runoff contaminated by oil, sediements, metals, and others.
U.S. Environmental Protection Agency (EPA) authorized the Texas Commission on Environmental Quality (TCEQ) in 1998 to administer the NPDES at state level under the name of Texas Pollutant Discharge Elimination System (TPDES). The TPDES is primarily conformed by three different permits:
- Industrial Storm Water Permit (TXR050000)
- Construction General Permit (TXR150000)
- Municipal Storm Water Permit (TXR040000)
The City of Alton in order to comply with this mandate created and implemented a Storm Water Management Plan (SWMP) with the collaboration of Texas A&M University-Kingsville and the Phase II Municipal Separate Storm Sewer System (MS4) Lower Rio Grande Valley Task Force (LRGVTF). As part of the SWMP seven minimum control measures (MCM) along with the utilization of best management practices (BMPs) have been implemented in order to reduce Storm Water pollution to the maximum extent practicable as required by TCEQ.
