Abstract:  THE 250-ACRE USA LETTERKENNY-PDO SITE IS WITHIN THE 19,500-ACRE ACTIVE US ARMY FACILITY IN CHAMBERSBURG, FRANKLIN COUNTY, PENNSYLVANIA. LAND USE IN THE AREA IS PRIMARILY AGRICULTURAL, WITH SCATTERED RESIDENCES AND MILITARY FACILITIES. SHALLOW GROUND WATER AT THE HEAD OF THE SITE FLOWS TOWARD AND INTO ROCKY SPRING AND ROCKY SPRING LAKE. SINCE 1942, THE US ARMY HAS USED THE PDO AREA TO OVERHAUL, REBUILD, AND TEST WHEELED AND TRACKED VEHICLES; DISTRIBUTE CLASS III CHEMICALS AND PETROLEUM; AND STORE, MAINTAIN, DEMILITARIZE, MODIFY, AND DEMOLISH AMMUNITION. THESE PAST INDUSTRIAL ACTIVITIES INVOLVED THE ONSITE USE OF SOLVENTS, OILS, HYDROCARBONS, AND METALS, WHICH WERE DISPOSED OF IN AN OIL BURNING PIT AND SEVERAL DRUM STORAGE REVETMENTS. FROM 1987 UNTIL 1989, A NUMBER OF EPA INVESTIGATIONS DOCUMENTED SOIL CONTAMINATION NEAR THE DRUM STORAGE AREA AND THE OIL BURNING PIT; AND THESE AREAS ARE THOUGHT TO BE THE PRIMARY SOURCES OF ONSITE CONTAMINATION. THIS RECORD OF DECISION (ROD) ADDRESSES REMEDIATION OF ONSITE SOIL AS THE FIRST OPERABLE UNIT (OU1). A SUBSEQUENT ROD WILL ADDRESS GROUND WATER CONTAMINATION AS OU2. BECAUSE A MAJORITY OF THE SOIL CONTAMINANTS HAVE ALREADY MOVED DOWN INTO THE CLAYS AND SILTS OF THE UNDERLYING BEDROCK AND GROUND WATER, SOIL CONTAMINANTS NOW POSE LOW RISKS FOR HUMANS AT THE SITE, AND NO REMEDIATION OF THE SOIL IS NECESSARY. BASED ON THIS RATIONALE, THERE ARE NO PRIMARY CONTAMINANTS OF CONCERN AFFECTING THIS SITE.

THE SELECTED REMEDIAL ACTION FOR THIS SITE IS NO ACTION. THERE ARE NO COSTS ASSOCIATED WITH THIS NO ACTION REMEDY.

PERFORMANCE STANDARDS OR GOALS; NOT APPLICABLE.
 
Remedy:  THE PDO OPERABLE UNIT ONE IS THE FIRST OF TWO OPERABLE UNITS FOR THE PDO AREA. THIS OPERABLE UNIT ADDRESSES THE CONTAMINATED SOILS BENEATH THE DRUM STORAGE REVETMENTS AND OIL BURNING PIT, WHICH ARE SUSPECTED SOURCES OF GROUNDWATER CONTAMINATION AT THE PDO AREA. A COMPLETE ASSESSMENT OF THE PDO AREA SOURCES AND GROUNDWATER/SURFACE WATER CONTAMINATION WILL BE DOCUMENTED IN THE FINAL REMEDIAL INVESTIGATION (RI), ENDANGERMENT ASSESSMENT, FEASIBILITY STUDY (FS) AND RECORD OF DECISION UPON COMPLETION OF THE ONGOING RI/FS PROGRAM. REMEDIAL ACTION ALTERNATIVES WERE NOT DEVELOPED FOR THE DRUM STORAGE REVETMENTS NOR THE OIL BURNING PIT, BASED ON THE RESULTS OF THE ENDANGERMENT ASSESSMENT (EA) FOR THE PDO AREA (ESE, 1988). RESULTS OF THE EA INDICATE THAT THE CONTAMINATED SOILS AT THESE LOCATIONS DO NOT POSE A CURRENT OR POTENTIAL THREAT TO HUMAN HEALTH OR THE ENVIRONMENT, AS MOST OF THE CONTAMINATION HAS MIGRATED TO THE BEDROCK AND GROUNDWATER. AS SUCH, THE SELECTED REMEDY FOR THIS OPERABLE UNIT IS "NO ACTION".
