Abstract:  THE DOUGLASSVILLE DISPOSAL SITE IS A 50-ACRE ABANDONED WASTE OIL PROCESSING FACILITY IN UNION TOWNSHIP, BERKS COUNTY, PENNSYLVANIA. THE AREA SURROUNDING THE SITE INCLUDES AGRICULTURAL LAND, RESIDENCES, AND LIGHT INDUSTRIAL DEVELOPMENT. THE SITE LIES ALMOST ENTIRELY WITHIN THE 100-YEAR FLOODPLAIN OF THE SCHUYLKILL RIVER, WHICH BORDERS THE SITE TO THE NORTH AND EAST. THE SCHUYLKILL RIVER IS USED FOR MUNICIPAL AND INDUSTRIAL WATER SUPPLY, RECREATIONAL PURPOSES, AND WASTE ASSIMILATION. FURTHER DOWNSTREAM OF THE SITE, SEVEN PUBLIC WATER SUPPLY USERS DRAW WATER FROM THE SCHUYLKILL RIVER. FROM 1941 TO 1979 THE SITE OPERATED AS A LUBRICATION OIL AND WASTE SOLVENT RECYCLING FACILITY. WASTES GENERATED FROM THE RECYCLING PROCESSES WERE STORED ONSITE IN SEVERAL LAGOONS. THE SITE CONSISTS OF A FORMER WASTE OIL PROCESSING AREA AND VARIOUS WASTE DISPOSAL AREAS. BECAUSE OF THE SITE'S SIZE AND THE COMPLEXITY OF THE VARIOUS ONSITE ACTIVITIES, THE SITE HAS BEEN DIVIDED INTO 10 SOURCE AREAS OF CONTAMINATION. DISPOSAL AREAS INCLUDE TWO BACKFILLED SLUDGE DISPOSAL LAGOONS (SOURCE AREAS 4 AND 5), AN OILY FILTER CAKE DISPOSAL AREA (SOURCE AREA 2), AN OIL DRUM STORAGE AREA (SOURCE AREA 8), AN AREA WHERE WASTE OIL SLUDGE WAS LANDFARMED INTO THE SOIL (SOURCE AREAS 3 AND 6), THE FORMER PROCESSING FACILITY/TANK FARM AREA (SOURCE AREA 1), A SMALL BACKFILLED LAGOON (SOURCE AREA 9), AN OLD INCINERATOR (SOURCE AREA 7), AND AN AREA OF SCRAP METAL AND TANKS (SOURCE AREA 10). IN 1970 HEAVY RAIN CAUSED A LAGOON TO OVERFLOW AND BREACH SAFETY DIKES; TWO TO SEVEN MILLION GALLONS OF WASTE FLOWED INTO THE SCHUYLKILL RIVER. TWO YEARS LATER, A HURRICANE CAUSED THE SCHUYLKILL RIVER TO OVERFLOW ITS BANKS AND INUNDATE THE ENTIRE SITE, RELEASING AN ESTIMATED SIX TO EIGHT MILLION GALLONS OF WASTE. EPA SUBSEQUENTLY DRAINED AND BACKFILLED THE LAGOONS. BEGINNING IN 1979 OPERATIONS CHANGED TO REFINING WASTE OILS FOR USE AS FUEL IN INDUSTRIAL BOILERS. OILY WASTEWATER SLUDGE FROM THE REFINING PROCESS WAS LANDFARMED IN THE AREA UNTIL 1981, WHEN THE STATE MANDATED OPERATIONAL CORRECTIONS TO THE LANDFARMING PRACTICES. ALL OPERATIONS CEASED IN 1985. THE 1988 RECORD OF DECISION (ROD) ADDRESSED THE RISKS ASSOCIATED WITH THE FORMER PROCESSING FACILITY/TANK FARM AREA, WHICH WERE IMPEDIMENTS TO ANY FUTURE SOIL AND GROUND WATER REMEDIATION. THIS SECOND AND FINAL RESPONSE ACTION ADDRESSES SOIL AND GROUND WATER CONTAMINATION REMAINING AFTER THE FORMER PROCESSING FACILITY/TANK FARM AND ASSOCIATED WASTES HAVE BEEN REMOVED OFFSITE. THIS ROD ALSO AMENDS, IN PART, THE 1985 ROD, WHICH OUTLINED THE REMEDIAL ACTION FOR THE SOURCE AREAS DESIGNATED AS 2, 4, AND 5 BUT DEFERRED A DECISION REGARDING GROUND WATER CONTAMINATION. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE SOIL, SEDIMENT, AND GROUND WATER ARE VOCS INCLUDING BENZENE, TOLUENE, AND VINYL CHLORIDE; OTHER ORGANICS INCLUDING PAHS, PCBS, AND PHENOL; AND METALS INCLUDING LEAD.


THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES EXCAVATION AND ONSITE THERMAL TREATMENT OF 48,400 CUBIC YARDS OF SOIL AND SLUDGES FROM SOURCE AREA 2, AND 600 CUBIC YARDS OF OILY SEDIMENT FROM THE DRAINAGE DITCH THAT RUNS FROM SOURCE AREA 9, FOLLOWED BY BACKFILLING ASH RESIDUE INTO SOURCE AREA 2; COVERING THE BACKFILLED AREA WITH CLEAN SOIL FOLLOWED BY REVEGETATION; CAPPING OF SOURCE AREAS 1, 4, AND 5 WITH ONE FOOT OF FLY ASH AND TWO FEET OF SOIL FOLLOWED BY REVEGETATION; IF ASH RESIDUES EXCEED EP TOXICITY LEVELS SOLIDIFICATION WOULD BE REQUIRED PRIOR TO ONSITE DISPOSAL; CAPPING SOURCE AREAS 3, 6, AND 9 (APPROXIMATELY 10 ACRES) WITH 1 FOOT OF CLEAN SOIL FOLLOWED BY REVEGETATION; IMPLEMENTING INSTITUTIONAL CONTROLS TO PREVENT SOIL DISTURBANCE AND WELL DRILLING; GROUND WATER AND SURFACE WATER MONITORING; AND ESTABLISHING ACLS FOR GROUND WATER. THE ESTIMATED PRESENT WORTH COST FOR THIS REMEDIAL ACTION RANGES FROM $39,430,000 TO $53,769,000 DEPENDING ON WHETHER ASH RESIDUE REQUIRES SOLIDIFICATION PRIOR TO DISPOSAL.
 
Remedy:  THIS OPERABLE UNIT IS THE FINAL ACTION OF TWO OPERABLE UNITS FOR THE SITE. THE FIRST OPERABLE UNIT AT THE SITE INVOLVES THE DISMANTLEMENT OF THE FORMER PROCESSING FACILITY/TANK FARM AREA. THIS SECOND OPERABLE UNIT ADDRESSES THE SOURCE OF THE CONTAMINATION BY REMEDIATION OF THE ONSITE SLUDGES AND CONTAMINATED SOILS. THE REMEDY ADDRESSES THE PRINCIPAL THREATS AT THE SITE BY (1) REDUCING THE RISKS ASSOCIATED WITH EXPOSURE TO THE CONTAMINATED MATERIALS IDENTIFIED AS 10 SOURCE AREAS, AND (2) PREVENTING EXPOSURE TO CONTAMINATED GROUND WATER BENEATH THE SITE.

THE MAJOR COMPONENTS OF THE SELECTED REMEDIAL ACTION INCLUDE;

* EXCAVATION AND TREATMENT, BY ONSITE THERMAL TREATMENT, OF APPROXIMATELY 48,400 CUBIC YARDS OF CONTAMINATED SOILS AND SLUDGES FROM SOURCE AREA 2 AND OILY SEDIMENT FROM THE DRAINAGE DITCH THAT RUNS FROM SOURCE AREA 9 TO THE SCHUYLKILL RIVER.
* DISPOSAL OF THERMALLY TREATED MATERIALS BY BACKFILLING INTO SOURCE AREA 2.
* COVERING THE BACKFILLED AREA WITH CLEAN SOIL FOLLOWED BY REVEGETATION.
* CAPPING SOURCE AREAS 1, 4, AND 5 WITH ONE FOOT OF FLY ASH AND TWO FEET OF SOIL FOLLOWED BY REVEGETATION.
* CAPPING SOURCE AREAS 3, 6, AND 9 (APPROXIMATELY 10 ACRES) WITH CLEAN SOIL FOLLOWED BY REVEGETATION.
* IMPOSING DEED RESTRICTIONS TO PREVENT SOIL DISTURBANCE AND WELL DRILLING ON THE PROPERTY.
* ESTABLISHING ACLS FOR GROUND WATER THAT WOULD NOT CAUSE ADVERSE EFFECTS ON THE SCHUYLKILL RIVER.
