This page addresses the sediment impairment in the Crow Creek Watershed. 

Section 303(d) of the Clean Water Act and the U.S. Environmental Protection Agency’s (EPA) Water-Quality Planning and Management Regulations (40 CFR Part 130) requires states to develop Total Maximum Daily Loads (TMDLs) for waterbodies that do not meet applicable water-quality standards or guidelines for protecting designated uses under technology-based controls. TMDLs specify the maximum pollutant amount a waterbody can receive and still meet water-quality standards. Based on a calculation of the total allowable load, TMDLs allocate pollutant loads to sources incorporating a margin of safety. TMDL pollutant load reduction goals for significant sources provide a scientific basis for restoring surface water quality and linking, developing, and implementing control actions to attain and maintain water-quality standards and designated uses.

This page identifies the components of a TMDL, supports adequate public participation, and facilitates the EPA review. The TMDL was developed in accordance with Section 303(d) of the federal Clean Water Act and guidance developed by the EPA.
