The 824-acre Naval Support Activity Mechanicsburg, formerly known as the Naval Inventory Control Point (NAVICP) located in Mechanicsburg, Cumberland County, Pennsylvania (7 miles West of Harrisburg PA. In the 1940s, NAVICP provided global management of repair parts for Navy ships. The base undertook additional inventory management responsibilities such as managing conventional ammunition, providing services, and providing maintenance and engineering for the installation. By 1943, 57 semi-permanent warehouses were built. In the early 1950s, NAVICP became a repository for a variety of metal ores received as war payment and reprimand. In Fall 1998, host activities at NAVICP (e.g., environmental and safety services, facilities, and engineering) were transferred to Commander in Charge of Atlantic Fleet (CINCLANTFLT) which resulted in an installation name change to Naval Support Activity (NSA), Mechanicsburg, Pennsylvania. At this time, NAVICP became a tenant command. The Navy conducted several investigations from 1984 to 1994. Upon doing so, six potential areas of contamination were identified: Carter Road Landfill, Building 904 Landfill, Ball Road Landfill and Burn Pits, Golf Course Landfill, Buildings 403/404 Solvent Disposal Area, and the Storm Water Drainage Ditch (SWDD). The 4.5-acre Carter Road Landfill, was used for the disposal of construction rubble, medical supplies, and gas mask canisters from 1950 to 1962. The 1-acre Building 904 Landfill, was used during the 1950s to dispose of construction debris and medical supplies. Ball Road Landfill and Burn Pits, was used from the mid-1940s until 1977. Wastes were dumped into the two pits over 7.5-acres, doused with gasoline and burned on a weekly basis. Wastes included paints, varnishes, gasoline, oils, medical supplies, paint and solvent containers, asbestos ash, and materials contaminated with polychlorinated biphenyls (PCB). The Golf Course Landfill was a 4-acre area where wastes were dumped and occasionally burned from 1945 to 1946. The Building 403/404 Solvent Disposal Area is the railroad track located between two buildings in the South-Central portion of the base. During the 1950s, hazardous wastes, including PCB-contaminated soils, and trichloroethene, were poured directly onto the tracks. The SWDD area receives the majority of the storm water runoff from the base. The drainage ditch is approximately 1.5 miles long and discharges into Trindle Run (a Pennsylvania cold water fishery) which then flows into the Conodoguinet Creek. The SWDD was primarily contaminated by a storm sewer system (AOC-9A) that was discharging PCB's from a transformer handling area to the ditch. Approximately 9,000 people obtain drinking water from public and private wells within 4 miles of the sources at NSA. Site Responsibility The site is being addressed through Federal actions.
