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 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.

TOTAL MAXIMUM DAILY LOAD (TMDL) RESPONSE PLANS
Section 303(d) of the Clean Water Act requires states to identify water bodies that do not meet surface water quality standards. A TMDL may be required when a water body is listed as impaired. A TMDL determines the maximum amount of a pollutant allowed to enter a water body so that water quality standards can still be achieved. The City of Durham is currently subject to a fecal coliform bacteria TMDL for the Northeast Creek watershed and a turbidity TMDL for the Third Fork Creek watershed. TMDL Response Plans were completed for both watersheds in 2019. The objectives of the TMDL Response Plans are to identify and implement measures that will reduce the levels of the targeted pollutants in Northeast Creek and Third Fork Creek. You can read the full plans at the links below.
