The Ports of Los Angeles and Long Beach form the largest port complexin the United States, occupying over 12,000 acres (48 square kilometers) of land andwater along 68 miles (110 kilometers) of waterfront. A draft Total Maximum Daily Load(TMDL) for Toxic Pollutants in the Dominguez Channel and Greater Los Angeles andLong Beach Harbor Waters (Los Angeles, California), expected to be completed in December2010, will address water quality impairments due to metals and organic compoundconcentrations in multiple environmental media (i.e., water column, sediment[toxicity and benthic community effects], and tissues). To ensure sediment managementactions are ecologically beneficial and logistically and economically feasible, a ContaminatedSediment Management Plan has been developed to identify, prioritize, and managechemically impacted sediments where necessary to protect/improve benthic communityhealth. The Contaminated Sediment Management Plan will use a risk-based approach toassess benthic impacts due to chemically mediated affects to determine the magnitudeand extent of cleanup actions. Port management actions will align remediation activitieswith port construction projects.
