City of Durham Stormwater Permit (NPDES Permit)
To have a storm drain system that carries rain water away from developed areas to creeks and lakes, the city is required by the federal Clean Water Act to have a National Pollutant Discharge Elimination System (NPDES) permit.
NPDES Annual Report
The city provides the state with an annual report on stormwater management. This report is required by the city’s federal National Pollutant Discharge Elimination System (NPDES) permit. The report for the most current reporting year, 2014-2015, can be found here (PDF). Archived reports from previous years can be found here.
The report provides information about new initiatives and programs, compares collected data to water quality standards, and summarizes water quality investigations. It also outlines how the city met the minimum permit requirements in the areas of: public education and outreach, public participation and involvement, illicit discharge detection and elimination, post-construction runoff, municipal pollution prevention and good housekeeping, industrial inspection, and water quality monitoring and assessment.
Note: Beginning in 2007-2008, the reporting period changed from running July 1 through June 30 to running from October 1 through September 30.
