The City of Pflugerville developed a Stormwater Management Program (SWMP) as required for coverage under the Texas Pollutant Discharge Elimination System (TPDES), administered by the Texas Commission on Environmental Quality (TCEQ). The purpose of this program is to protect and enhance the water quality of streams, creeks, tributaries, lakes, springs, and wetlands.
Stormwater is considered to be any rainwater that doesn't get absorbed into the ground and instead flows downwards to a water body. Impervious surfaces (any surfaces preventing water infiltration into the ground, e.g. buildings and pavement) significantly decrease the amount of absorption and increases the volume and rate of water flowing into our ground waters & surface waters. As water flows over impervious surfaces it carries any pollutants with it, such as motor vehicle fluids, yard fertilizers, pesticides, pet waste, trash, oils, greases, silts, sediments and any other chemicals in contact with the stormwater.
As development and urbanization expand across the country, so does the degradation of our nations water resources, e.g. springs, streams, creeks, rivers, wetlands, and lakes. These factors led to the establishment of the Clean Water Act and the National Pollutant Discharge Elimination System (NPDES) permitting program that is administered by the Environmental Protection Agency (EPA). With this regulatory framework, the EPA began to grant permits to discharge stormwater with the intent of maintaining the chemical, physical and biological integrity of the waters of the United States.
For the first 20 years, the EPA prioritized Phase 1 dischargers, i.e. industrial facilities, large construction sites and municipalities with populations over a 100,000. However, in 1995 the EPA issued a final rule for Phase II operators, requiring municipalities with a population of less than a 100,000 to apply for stormwater permits by August 7, 2001.
The City of Pflugerville has an approximate population of 53,752 residents and was, therefore, issued a Phase II, level III Municipal Stormwater Permit in 2007 by the TCEQ. The Permit authorizes the City to directly discharge stormwater from the municipal separate storm sewer system (MS4) to ground waters and surface waters of the state. As part of complying with the TPDES MS4 Permit, the City has to develop and implement a Storm Water Management Program (SWMP). The SWMP focuses on five Minimum Control Measures to reduce the negative impacts of stormwater runoff and enhance water quality.
- Public Education, Outreach and involvement
- Illicit Discharge Detection and Elimination
- Construction Site Stormwater Runoff Control
- Post-Construction Stormwater Management in New Development & Redevelopment
- Pollution Prevention/Good Housekeeping for Community Operations
The City of Pflugerville must submit a yearly annual report to the TCEQ in order to demonstrate compliance with the General Permit. Please see the following links for copies of the City's Annual Reports:
