||In 1998, the District of Columbia developed a list of waters that do not or are not expected to meet water quality standards as required by section 303(d)(1)(A). The list was revised in 2002. The list of water bodies contains a priority list of those waters that are the impaired. This priority listing is used to determine which of those water bodies are in critical need of immediate attention. The list, also known as the 303(d) List, is submitted to the Environmental Protection Agency every two years. For each of the listed waters, states are required to develop a Total Maximum Daily Load (TMDL) which calculates the maximum amount of a pollutant that can enter the water without violating water quality standards and allocates that load to all significant sources. Pollutants above the allocated loads must be eliminated. This TMDL is for fecal coliform bacteria for Rock Creek. The District of Columbia's section 303(d) list divides Rock Creek into two segments: Upper Rock Creek and Lower Rock Creek. The demarcations are used to isolate the areas not attaining the applicable standards. The same water quality standards for fecal bacteria, however, apply to the entire length of Rock Creek.
