Abstract:  THE 2-ACRE SEALAND LIMITED SITE, A FORMER COAL TAR TREATMENT AND RECYCLING FACILITY, IS LOCATED IN MT. PLEASANT, NEW CASTLE COUNTY, DELAWARE. LAND USE IN THE AREA IS PRIMARILY INDUSTRIAL AND COMMERCIAL. CURRENT SITE FEATURES INCLUDE A CONCRETE SLAB, A ONE-STORY BUILDING, AN ABANDONED RAIL SPUR, A GRAVEL ROAD, AND MISCELLANEOUS DEBRIS. GROUND WATER UNDERLYING THE SITE IS USED AS A SOURCE OF DRINKING WATER. FROM 1971 UNTIL 1976, ADAMS LABORATORY USED THE SITE FOR ANIMAL FAT RENDERING ACTIVITIES. THE PROPERTY WAS SUBSEQUENTLY SOLD TO CONRAIL, WHICH CLEANED UP THE PROPERTY TO MEET STATE STANDARDS IN 1979. FROM 1982 TO 1983, CONRAIL LEASED THE PROPERTY TO SEALAND. SEALAND ALLEGEDLY CONDUCTED TREATMENT, PROCESSING, AND RECYCLING OF COAL TO TAR AND OFF- SPECIFICATION CREOSOTE WASTES ONSITE UNTIL ABANDONING THE SITE IN 1983. A 1983 STATE INVESTIGATION DISCOVERED 21 STEEL TANKS OR HOPPERS; A 10,000-GALLON WOODEN STORAGE TANK AND 300 55-GALLON STEEL DRUMS, WHICH WERE LEAKING LIQUIDS ONSITE; A BOILER HOUSE; AND VARIOUS MIXING CHAMBERS AND PRESSURE VESSELS ON THE ABANDONED SITE. ADDITIONAL STUDIES BY EPA AND THE STATE IDENTIFIED ORGANICS INCLUDING PAHS, CREOSOLS, AND SOLVENTS IN THE ONSITE SOIL, DRUMS, AND TANKS. SUBSEQUENTLY IN 1983, EPA CONDUCTED AN EMERGENCY REMOVAL ACTION AT THE SITE AND REMOVED OFFSITE 240,000 GALLONS OF ORGANIC WASTES FROM WITHIN THE WOODEN AND STEEL TANKS, AND 320 DRUMS. ADDITIONALLY, EPA DISPOSED OF 122 CUBIC YARDS OF SOLID WASTE, INCLUDING 30 CUBIC YARDS OF WOODEN TANK DEBRIS AND APPROXIMATELY 50 TO 92 CUBIC YARDS OF SLUDGE AND CONTAMINATED MATERIAL OFFSITE. THE OWNER VOLUNTARILY REMOVED 239 DRUMS OF OFF-SPECIFICATION PRODUCT. IN ADDITION, THE STORAGE TANKS WERE CLEANED AND MOVED, AND THE TANK AND DRUM STORAGE AREA WAS CAPPED WITH CLAY. THIS RECORD OF DECISION (ROD) ADDRESSES ONSITE SOIL AS THE FIRST AND FINAL OPERABLE UNIT (OU1). ALL HAZARDOUS MATERIALS CONTAINED IN ABANDONED ONSITE TANKS AND DRUMS WERE DISPOSED OF OFFSITE DURING THE EPA REMOVAL ACTION, AND ANY REMAINING SOIL CONTAMINANTS POSE LOW RISKS FOR HUMANS AT THE SITE. 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 SELECTED REMEDY FOR THE SEALAND LIMITED SITE IS NO ACTION. UNDER THIS ALTERNATIVE, NO FURTHER ACTION WILL BE TAKEN AT THE SITE. ALTHOUGH NOT REQUIRED BY EPA POLICY OR GUIDANCE, A REVIEW OF THE CONDITION OF THE SITE WILL BE CONDUCTED IN FIVE YEARS TO VERIFY THAT NO UNACCEPTABLE HAZARDS ARE POSED BY CONDITIONS WHICH THEN EXIST AT THE SITE.
