Naval Training Center (NTC)-Bainbridge was constructed in 1942 as a training center for World War II Navy Recruits. The facility was partially deactivated after World War II, but experienced major activity following the beginning of the Korean War in 1951. In the post-war years, NTC-Bainbridge became the host for various schools and functions, including the Naval Preparatory School, the Nuclear Power School, the Naval Reserve Manpower Center, WAVES Headquarters, and a U.S. Naval Hospital. Operations at NTC-Bainbridge were reduced in 1972, and NTC-Bainbridge was formally closed in 1976. The United States Navy has retained ownership, although no Navy operations have been
conducted since 1976. The Department of Labor operated a Job Corp Training Center on part of the installation until 1990.
Site 1, Old Base Landfill (OBL), is located in the northwest boundary of the NTC-Bainbridge, separated from Route 276 by a facility fence and a small-unnamed stream (Figure 2-2). The OBL was a solid waste landfill that operated from 1942 until base closure in 1976. Disposal activities were unregulated and the landfill is unlined. Although disposal records were not kept, it is known that pesticides and asbestos-transite laden building debris were disposed at the site. In 1995 the landfill was capped as an Interim Remedial Measure (IRM). Repairs and extensions to the cap were made in 1999.
Site 2, Fire Training Area (FTA), is located on the southeastern corner of the NTC-Bainbridge and bounded by Happy Valley Branch (HVB) near Maryland Route 222 (Figure 2-2). The FTA was used to train Navy recruits in fire fighting techniques from the 1940 until the late 1960s. The training involved spraying buildings with oil and igniting them. When the flames were extinguished with water, oil and water run-off drained into two subsurface concrete vaults off the southwest corner of the concrete pad. Overflow from the vaults went into an oil-water separator pit, then through a subsurface valve and piping system discharging into a shallow ditch leading to HVB. Remediation, conducted during 1994-1995, was completed as an IRM and included thee excavation of 37,950 cubic yards of oil, debris, and pesticide-contaminated soil. Soil excavated from FTA was transported to the OBL for disposal under an impermeable landfill cap. The former oil-water separator pit was restored as a wetland.
Alternative 2: Institutional Controls
· Site-specific deed restrictions preventing intrusive activities on the cap of the Old Base Landfill (OBL). No construction of any kind may commence or be accomplished at the OBL without written authorization for such activity having first been obtained from the Navy and the Secretary of the Maryland Department of the Environment. The restriction is intended to prevent any activity that could result in damage to, or erosion of the protective landfill cap. The OBL must be inspected, maintained, and monitored in accordance with Maryland Laws and Regulations for landfills.
· A long-term ground water, surface water, and sediment monitoring program at locations down gradient of OBL, with mandatory reviews by environmental regulatory agencies. The long term monitoring program (LTMP) for OBL and Fire Training Area (FTA) will be designed and implemented on the basis of an agreement between the Navy and the United States Environmental Protection Agency (EPA) Region 111. The LTMP will include mandatory provisions for periodic Navy/regulator reviews. Monitoring Program Reviews will be scheduled to occur at five-year intervals; however, the frequency of reviews will include an evaluation of potential trends in the environmental analytical data collected and site-walkovers to assess the condition off the OBL cap. The Navy/regulatory review of the protectiveness of the Selected Remedy will include determinations for potential follow-on actions including potential revisions to the environmental monitoring as deemed appropriate.
· In accordance with Section 120(h) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the ICs will include a clause in the transfer deed that grants the United States Navy such access to the property in any case in which a response action, or corrective action is found to be necessary on the property following property transfer. ICs will provide rights of access to conduct tests, investigations, and surveys, including, where necessary, well drilling, digging test pits, boring, and other similar activities.
· Deed restriction preventing the use of groundwater at the OBL and FTA for potable water supplies. Human health risk assessments conducted for OBL and FTA, as part of the Remedial Investigation (RI) and post-RI human health risk characterization, have identified unacceptable risk to human health based upon consumption and exposure to ground water under residential-use scenarios. Therefore, a deed restriction on ground water will be implemented at these sites. Any ground water wells or other use of ground water located on the sites must comply with all Federal, state, and local requirements relating to ground water use. In addition, in the three (3) areas illustrated in Figures 2-3 and 2-4 and defined in the transfer deed, ground water shall not be used for drinking water unless the concentration of manganese has been reduced to three hundred parts peer billion (300 ppb) at the users tap and the concentration of iron has been reduced to four thousand and six hundred parts per billion (4,600 ppb) at the user's tap. Use of ground water for non-potable, industrial processes will not be restricted, however, the use of ground water for non-potable, industrial processes is assumed to not include frequent human contact. Annual inspections and IC certification reports will be prepared by the Navy to insure that the ICs have not been violated.
