This document, upon approval by the U.S. Environmental Protection Agency (EPA), establishes a Total Maximum Daily Load (TMDL) for sediment in the Maryland 8-digit (MD 8-digit) Antietam Creek watershed (basin number 02140502) (303(d) Assessment Unit ID: MD- 02140502). Section 303(d) of the federal Clean Water Act (CWA) and the EPAs implementing regulations direct each state to identify and list waters, known as water quality limited segments (WQLSs), in which current required controls of a specified substance are inadequate to achieve water quality standards. For each WQLS, the State is required to either establish a TMDL of the specified substance that the waterbody can receive without violating water quality standards, or demonstrate that water quality standards are being met (CFR 2007b). A data solicitation for sediments was conducted by MDE, and all readily available data from the past five years have been considered. A TMDL for Carbonaceous Biochemical Oxygen Demand (CBOD) and Nitrogenous Biochemical Oxygen Demand (NBOD) to address the 1996 dissolved oxygen listing was approved by the EPA in 2002. A Water Quality Analysis (WQA) of Eutrophication to address the 1998 nutrients listing for the Greenbrier Lake impoundment was approved by the EPA in 2005. The listings for nutrients and impacts to biological communities will be addressed separately at a future date, and the bacteria listing is being addressed via a TMDL that is scheduled to be submitted to the EPA in the Summer of 2008.
