Baltimore Harbor Watershed in Baltimore City and Baltimore County, Maryland
Notice of Intent to Establish a TMDL of Trash/Debris
Section 303(d) of the federal Clean Water Act requires Maryland (MD) to: (1) identify waters, known as water quality limited segments (WQLSs), where technology-based effluent limitations and other required controls cannot achieve water quality standards; (2) for each listed water, establish Total Maximum Daily Loads (TMDLs) for pollutants preventing the attainment of water quality standards; and (3) offer an opportunity for public review and comment on the proposed TMDLs.
Baltimore Harbor (basin code 02130903) was listed as impaired by sediments (1996), nutrients (1996), bacteria (1998), polychlorinated biphenyls (PCBs, 1998), various metals (1998), impacts to biological communities (2002) and debris/floatables/trash, specifically portions of Middle Branch and Northwest Harbor (2008). The document establishes a TMDL for trash and debris for the Middle Branch and Northwest portions of the Baltimore Harbor. The impairments due to the additional contaminants have been or will be addressed in separate analyses conducted by MDE.
The TMDLs set the maximum load limit for the impairing substance. The TMDLs also reflect load allocations to point sources, nonpoint sources and a margin of safety that accounts for uncertainty in the procedures used to estimate the TMDLs. Once established by the State, the TMDLs will be subject to approval by the United States Environmental Protection Agency (EPA). The approved TMDLs will support measures needed to attain water quality standards in the Middle Branch and Northwest Branch portions of the Baltimore Harbor.
