Site DescriptionThe Curtis Bay Coast Guard Yard occupies 113 acres on the east side of Curtis Creek, south of Hawkins Point Road. The site is six miles southeast of downtown Baltimore in Anne Arundel County. The facility provides support for the U.S. Coast Guard, including the design, construction and repair of ships and boats. During its peak use during World War II, the yard was a fully operational shipbuilding facility employing over 3,000 workers round-the-clock.
Site ResponsibilityThe U.S. Coast Guard is responsible for the site.
NPL Listing HistoryProposed to the National Priorities List in September 2001, the Curtis Bay Coast Guard Yard's NPL listing was finalized In September 2002.
Threats and ContaminantsFormer site related activities are suspected to have to contributed to contamination of soils, groundwater, surface water and sediments at the site. Samples collected at the site show that the soil is contaminated in certain areas with semi-volatile organic compounds, metals, polychlorinated biphenyls (PCBs), pesticides and dioxin. Sediment samples taken in Curtis Creek have indicated elevated metals concentrations. Current Coast Guard activities/waste management practices have been modified and/or discontinued to minimize contribution potential future release of contaminants from the site.
Contaminant descriptions and risk factors are available from the Agency for Toxic Substances and Disease Registry, an arm of the CDC.
A Remedial Investigation and Feasibility Study (RI/FS) was completed for Site 1 (Curtis Creek Sediments) It was determined that the low levels of contamination in the sediment do not pose an unacceptable risk to Human Health or the Environment. A No Action Record of Decision (ROD) for Site 1 was signed in September 2007.
Soils at Site 4 (former salvage lot), which contained elevated levels of lead and PCBs, were excavated and removed from the Yard under a Removal Action conducted between November 2007 and March 2008. A No Further Action ROD was signed for Site 4 in May 2009.
An RI/FS has been completed for Site 7 (former Burn Pit). The Selected Remedy includes excavation of contaminated soils and treatment of contaminated groundwater. A ROD was signed in September 2009. Removal of contaminated soils has been completed and treatment of groundwater was conducted. Ongoing groundwater monitoring is being conducted.
Site 8, Former Incinerator Site - A Removal Action has been completed for the excavation and removal of contaminated soil. A No Further Action ROD was signed for Site 8 in September 2011.
Site 9, Reported Bilge Spoils Area - A Removal Action has been completed for the excavation and removal of contaminated soil. Dredging of contaminated sediment has been completed.
Four additional Areas of Concern were also investigated as part of an Expanded Site Investigation. A No Further Decision Document was signed in June 2010.
A Public Health Assessment (PHA) was completed and finalized by the Agency for Toxic and Disease Registry (ATSDR). The results of the PHA did not determine that Coast Guard activities in the area have contributed to or have the potential to contribute adverse impact to workers or residents in the area.
