These were done to address the impairments noted on the 1996 Pennsylvania Section 303(d) list of impaired waters, required under the Clean Water Act, and covers one segment on that list and additional segments on later lists/reports. Deer Creek is currently listed for impairments due to metals, pH and siltation. The TMDL addresses the three primary metals associated with acid mine drainage (iron, manganese, aluminum) and pH, the siltation impairments will be addressed in future TMDLs.
