Abstract:  Please note that the text in this document summarizes the Record of Decision for the purposes of facilitating searching and retrieving key text on the ROD. It is not the officially approved abstract drafted by the EPA Regional offices. Once EPA Headquarters receives the official abstract, this text will be replaced.

The Naval Inventory Control Point (NAVICP), formerly the Navy Ships Parts Control Center (SPCC), occupies approximately 824 acres in Hampden Township and the Borough of Mechanicsburg, Pennsylvania. Land usage encompasses open storage areas, buildings/warehouses, roads, railroads, and improved grounds. The land use in the areas surrounding the NAVICP is mixed, including industrial, recreational, commercial, and residential areas. There are no surface water bodies on the NAVICP. In May 1994, the site was placed on the National Priorities List (NPL).

Operable Unit 3 (OU3):
The Carter Road Landfill (Site 1), is a flat grassy area, encompassing 4.5 acres of land along the southwest boundary of the NAVICP. Three aggregate pads cover most of the site.
Site 1 is a former disposal area, that was used from 1950 to 1962 for the disposal of construction rubble and some medical supplies (dextrose and glucose solutions) and gas mask canisters. It is currently used for temporary storage. The NAVICP Master Plan identities future land use at Site 1 as temporary storage. The bedrock underlying Site 1 is identified as limestone belonging to the Rockdale Run Formation. The aquifer underlying the site is unconfined and recharged by rainwater infiltration. Depth to the water table varies seasonally and is typically below the bedrock surface. The Mechanicsburg Water Company withdraws water from the aquifer at a well located approximately 3,500 feet from the southwest corner of the NAVICP, which is approximately 4,200 feet west of Site 1. Groundwater enters Site 1 from the west and north and flows south and east to Cedar Run.

A Record of Decision (ROD) was completed in September 1998, addressing groundwater, surface soil, and subsurface soil at Site 1.
Remedy:  The selected remedy will prohibit the use of the property for residential purposes. Within 90 days of signing this Record of Decision (ROD), the Navy will send a plat of the site containing a note describing the land use restriction to the Northern Division's real estate division and a request to document the institutional controls on the Navy Inventory Control Point (NAVICP) summary map. In addition, NAVICP will incorporate these restrictions and include the plat with any real property documents necessary for transferring property interests, in the unlikely event that the Navy transfers any part of the site by sale or lease. The real property document will also include a discussion of the National Priorities List (NPL) status of the site as well as a description of the contaminants of concern in soil.

Within 90 days of signing this ROD, the NAVICP installation commander shall prohibit residential use of the site by issuing an order or directive. The NAVICP installation commander shall be responsible for enforcing the prohibition on residential use. A copy of the site plat will be kept on file with NAVICP Public Works Department.

The NAVICP shall conduct annual field inspections of the site to determine whether current land use remains protective and consistent with the restrictions on residential use selected in this ROD. The installation commander shall certify continued compliance with the residential use restrictions in an annual report to the Chief of the Federal Facilities Branch, Hazardous Site Cleanup Division at the EPA and the Chief of the Hazardous Sites Cleanup Section, Environmental Cleanup Program at the Pennsylvania Department of Environmental Protection (PADEP). If a violation occurs, a description of the violation and corrective actions to be taken will be reported immediately to EPA and PADEP. NAVICP is an active military installation with no plans for closure in the foreseeable future. Therefore, under current and future use conditions, future residential development is unlikely.
