Section 303(d) of the federal Clean Water Act (CWA) directs States 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 establish a Total Maximum Daily Load (TMDL) of the specified substance(s) that the waterbody can receive without violating water quality standards, demonstrate that another program or action will achieve water quality standards, or demonstrate via the development of a Water Quality Analysis (WQA) that water quality standards for the specified substance(s) are currently being achieved. The Maryland Department of the Environment (MDE) hereby gives notice of the public availability of a draft TMDL document for Sediment for Back River Watershed (basin code 02130901). This document was available for public review previously from June 15, 2017 through July 14, 2017. However, due to a calculation error in the WLA, the TMDL and the report had been revised. Following EPA guidance, a second 30-day public comment period will be made available to the public for review and comment. Details are below.
