Regulatory Background
On November 21, 2008, the City of Duncanville received authorization of its Texas Pollutant Discharge Elimination System General Permit from the Texas Commission on Environmental Quality (TCEQ). The general permit requires the City of Duncanville, a Phase II Small MS4 (municipal separate storm sewer system), to implement a Storm Water Management Plan (SWMP) within the 5-year general permit term. The City of Duncanville's SWMP includes best management practices developed for each of the following six minimum control measures:
- Public education and outreach on stormwater impacts;
- Public involvement / participation;
- Illicit discharge detection and elimination;
- Construction site storm water runoff control;
- Post-construction storm water management in new development and redevelopment; and
- Pollution prevention / good housekeeping for municipal operations.
The best management practices set forth in the initial 5-year permit term were continued until TCEQ could develop new guidelines for implementation for Year 6 forward. The new guidelines have now been established and the city will adapt those policies into its next permit application.
