The Maryland Department of the Environment (MDE) has identified the waters of the Little Youghiogheny River on the States 303(d) List submitted to the EPA by MDE as impaired by nutrients (1996 and 1998), sediments (1996), bacteria (2002), metalsmethylmercury (2002), and impacts to biological communities (2002) (MDE 2006a). The designated use of the Little Youghiogheny River is Use III-P (Nontidal Cold Water and Public Water Supply) (COMAR, 2006a). This docume nt proposes to establish a TMDL for sediments in the Little Youghiogheny River to allow for the attainment of the above mentioned designated use. The objective of the sediment TMDL established in this document is to ensure that there will be no sediment impacts affecting aquatic health, when aquatic health is evaluated based on Marylands biocriteria (Roth et al., 2000, Roth et al., 1998 and Stribling et al., 1998), thereby establishing a sediment load that supports the Use III-P designation for the Little Youghiogheny watershed. The watershed sediment load includes the potential effect for water clarity and erosional and depositional impacts, thus accounting for all of the sediment impacts that indicate a sediment impairment per the Maryland 303(d) listing methodology (MDE, 2006b).
