Current Site Status

EPA and the AF have negotiated the FFA (Federal Facility Agreement). The FFA was signed by EPA and the Air Force. The 45-day comment period ended and the FFA was finalized as of December 5, 2011.

EPA and Maryland Department of the Environmental (MDE), and Prince George County Health Department (PGCHD) continue to work with the U.S. Air Force (AF) to investigate and pursue clean up of the site. Members of the Air Force, MDE, PGCHD and EPA continue to meet to develop work plans, discuss and resolve technical issues pursuant to ensuring the cleanups are consistent with regulations and proceed in an expedited fashion. Numerous hazardous substances have been identified at the site as detailed under "Threats and Contaminants" .

Several investigations are well under way or are complete. The EPA, MDE, and PGCHD have reviewed several remedial investigation (RI) reports. Investigations are ongoing for SS-28 Hangar 1516, and LF-06 (Landfill 6), LF-07, BLNA (Base Lake North Area, and several MMRP sites. Progress has slowed at LF-06. LF-07, and BLNA due to a disagreement between the AF and Solid Waste Division within Maryland Department of the Environment as of March 2010. Discussions continue between the Air Force and Maryland Department of the Environment.

Site Description

Joint Base Andrews (JBA) Naval Air Facility Washington formerly Andrews Air Force Base (AAFB) is an active U.S. Department of Defense facility that occupies about 4,360 acres of land in Camp Springs, Prince George's County, Maryland, about 5 miles southeast of Washington, DC. AAFB was established as the Camp Springs Army Air Field in 1942 and became AAFB in 1947. AAFB serves as the headquarters of the 11th Wing and is host to about 50 tenant units. AAFB supports worldwide airlift support operations for the President of the United States and other high-ranking domestic and foreign dignitaries, and supports the flight operations of more than 100 aircraft.

The Air Force (AF), EPA, Maryland Department of the Environment (MDE), and Prince George's County health Department (PGCHD) in July 2001, identified 73 sites or areas of concern to be investigated under Superfund. Of these, the AF previously identified 23 sites and 11 Areas of Concern (AOCs). EPA and the Air Force have identified 16 sites that require a RI/FS and six are part of the Military Munitions Response Program (MMRP) that require investigation as part of the (FFA) or Interagency Agreement (IAG).

Lead and numerous semi-volatile organic compounds have been detected historically at significantly elevated concentrations in Piscataway Creek. Lead was documented in Piscataway Creek at concentrations above the Ambient Water Quality Criteria in 1993. Surface water migration pathway targeted wetlands, a fishery in Piscataway Creek downstream of AAFB, migratory runs of anadromous fish, and an area of critical state concern. Shallow groundwater is contaminated with volatile organic compounds at several sites. Some have remedies in place through issuance of a record of decision (ROD) while other are being investigated.

Site Responsibility

Cleanup of this site is the responsibility of the federal government.

NPL Listing History

This site was proposed to the National Priorities List of the most serious uncontrolled or abandoned hazardous waste sites requiring long-term cleanup action on July 28, 1998. The site was formally added to the list May 10, 1999, making it eligible for federal cleanup funds.

Threats and Contaminants

Investigations have revealed the presence of numerous hazardous substances on site. These substances include lead, mercury, chromium, and cadmium; volatile organic compounds, such as tetrachloroethylene; semi-volatile organic compounds, predominantly polynuclear aromatic hydrocarbons such as acenaphthene, benzo(a)pyrene, and fluoranthene; and polychlorinated biphenyls.

Contaminant descriptions and risk factors are available from the Agency for Toxic Substances and Disease Registry, an arm of the CDC.

Cleanup Progress

EPA, Maryland Department of the Environment (MDE), and Prince George County Health Department (PGCHD) continue to work with the AF to accelerate cleanups. The first record of decision (ROD) was signed for ST-10, PD-689 Spill site in September 2005, and the ROD for FT-04, Fire Training Area 4 was signed in November 2005. These two RODs built on treatability studies initiated at the sites to remediate groundwater. It is expected that groundwater at these two sites may attain cleanup within 10-years from implementing the treatment. The Air Force and EPA are re-evaluating the cleanup performance.

The Base Wide Background Study is complete. The Base Wide Ecological Risk Assessment (BERA) is complete. The ROD at FT04 supports the construction of a readiness facility for the Air National Guard (ANG) at Andrews AFB. The ANG will provide air support for the Washington DC area. ANG construction is complete at FT04.

Numerous documents are being reviewed and investigations were completed. The ROD for LF-05, Leroy's Lane Landfill was sign in July 2009. The remedial design, remedial action work plan are complete. The remedial design (RD) was accepted and the remedial action (RA) field work began in November 2009 and is now complete as of July 2012. A RCRA Cap, funnel/gate permeable reactive barrier, monitoring, institutional controls, and off-base in-situ groundwater treatment are components of the remedy.

Records of decision (RODs) were signed for ST-10 September 28, 2995, FT-04 Fire Training Area 3 on November 22, 2005, SD-23 Sludge Disposal Area May 23, 2007, ST-14 East Side Service Station (Groundwater Contamination of TCE, Carbon Tetrachloride with several small petroleum plumes) on September 21, 2007, FT-03 Fire Training Area 2 on September 30, 2008, LF-05 Leroy's Lane Landfill on July 21, 2009, FT-02 Fire Training Area 1 on October 16, 2009, and SS-27 on September 14, 2011. The remedial designs and remedial actions are all complete.

The ROD or RODs for LF-06, LF-07 and BLNA will be delayed based upon the disagreement between the Solid Waste Division of Maryland Department of the Environment and the AF. The first base-wide Five-Year Review Report for sites with remedies in place was signed in March 2011 by the Air Force. EPA concurred with the Air Force that the remedies are protective on May 17, 2011.

EPA reviewed operations and maintenance plans for ST-10, FT-02, FT-03, ST-14, as well as LF-05. Numerous investigations are underway and they include SS-26 and SS-28. The Air Force issues a blanket performance based contract (PBC) for all the sites at Andrews AFB which were identified in the FFA. EPA, MDE and PGCHD are reviewing the site-specific work plans for the twenty sites. As part of the FFA, the site management plan is being reviewed.

The Air Force recently gained access to an adjacent property outside the fence at LF-05 Leroy's Lane Landfill. Polychlorinated biphenyls (PCBs) in shallow groundwater above the maximum contaminant level at 0.65 ug/L or parts per billion (ppb) which is above the maximum contaminant level (MCL) of 0.5 ug/L. The Air Force issued a letter to the private property owner the week of December 12, 2011.

Several work plans for Uniform Federal Policy Quality Assurance Plans (UFPQAPs) have been reviewed and finalized in accordance with the FFA. In addition, removals are planned for two water towers SWMU 75 (Solid Waste Management Unit) and SWMU 76. EPA received the signed the Action Memorandums in March 2013. In addition, an engineering evaluation/cost estimate (EE/CA) is planned for the Base Chapel CB-C501 and well as the MMRP (Military Munition Response Program) sites the Former Skeet Range, Trap and Skeet Club, and Small Arms Range was finalized in April 2012. The MMRP removal begin the July 2013. An EE/CA is also planned for Piscataway Creek and the removal began in July 2013. The removal and confirmatory sampling continues at both these sites. In addition, final UFPSAPs have been submitted for OW-C3640 Oil Water Separator and SWMU-66 D-5 Hard Landfill. The UFPSAPs were finalized for SWMU-69 Helicopter Fire Training Area, SWMU-56 Civil Engineering Yard, and CS-C503 Pond Sediments. The draft reports for SWMU-56 and CS-C503 have been reviewed.

Additional UFPSAPs will be submitted in the end of December 2012. The final feasibility Study was received for SS-26. EPA reviewed the supporting information for the draft ESD for FT-04 for manganese in September 2013. The remedial action completion report (RACR) for LF-05 Leroy's Lane Landfill Cap was signed by the Commanding Officer in October 2013 documenting that the remedy is in place. The Interim RACR for Leroy's Lane Landfill for groundwater was also signed documenting the implementation of the in-situ groundwater injections.
