Abstract:  THE 20-ACRE ACME SOLVENT RECLAIMING SITE IS A FORMER INDUSTRIAL DISPOSAL SITE IN WINNEBAGO COUNTY, ILLINOIS. LAND USE IN THE AREA IS MIXED AGRICULTURAL AND RESIDENTIAL. THE SITE IS BOUNDED BY AN ACTIVE QUARRY TO THE NORTH, FARMLAND TO THE SOUTH AND EAST, AND THE PAGEL'S PIT SUPERFUND SITE TO THE WEST. AN ONSITE STREAM, WHICH IS A TRIBUTARY OF KILBUCK CREEK, EVENTUALLY DRAINS INTO THE ROCK RIVER TO THE SOUTH. THE SITE OVERLIES TWO AQUIFERS, WHICH ARE USED BY THE ESTIMATED 400 RESIDENTS WHO LIVE WITHIN 2 MILES OF THE SITE AS THEIR DRINKING WATER SUPPLY. FROM 1960 TO 1973, ACME SOLVENT RECLAIMING DISPOSED OF PAINTS, OILS, AND STILL BOTTOMS ONSITE FROM ITS SOLVENT RECLAMATION PLANT. WASTES WERE DUMPED INTO DEPRESSIONS CREATED FROM PREVIOUS QUARRYING AND LANDSCAPING OPERATIONS, AND EMPTY DRUMS ALSO WERE STORED ONSITE. STATE INVESTIGATIONS IN 1981 IDENTIFIED ELEVATED LEVELS OF CHLORINATED ORGANIC COMPOUNDS IN GROUND WATER. A 1985 RECORD OF DECISION (ROD) PROVIDED FOR EXCAVATION AND ONSITE INCINERATION OF 26,000 CUBIC YARDS OF CONTAMINATED SOIL AND SLUDGE, SUPPLYING HOME CARBON TREATMENT UNITS TO AFFECTED RESIDENCES, AND FURTHER STUDY OF GROUND WATER AND BEDROCK. DURING ILLEGAL REMOVAL ACTIONS TAKEN BY PRPS IN 1986, 40,000 TONS OF SOIL AND SLUDGE WERE REMOVED FROM THE SITE. A 4,000-TON WASTE PILE AND 2 TANKS CONTAINING CONTAMINATED LIQUIDS REMAIN ONSITE, AND SINCE THEN AN ADDITIONAL 2,000 TONS OF ONSITE CONTAMINATED SOIL AND SLUDGE HAS BEEN DISCOVERED. THIS ROD WILL ADDRESS WASTE AREAS REMAINING AFTER THE 1986 REMOVAL, INCLUDING SOIL, BEDROCK, AND GROUND WATER, AS PART OF OU2. A FUTURE ROD WILL ADDRESS AN AREA OF GROUND WATER CONTAMINATION BETWEEN THE ACME SOLVENT RECLAIMING AND PAGEL'S PIT SITES AS OU3. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE SOIL, SLUDGE, AND GROUND WATER ARE VOCS INCLUDING BENZENE, PCE, TCE, AND XYLENES; OTHER ORGANICS INCLUDING PCBS; AND METALS INCLUDING ARSENIC, CHROMIUM, AND LEAD.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES EXCAVATING AND TREATING 6,000 TONS OF SOIL AND SLUDGE FROM TWO WASTE AREAS, USING LOW-TEMPERATURE THERMAL STRIPPING; TREATING RESIDUALS USING SOLIDIFICATION, IF NECESSARY, FOLLOWED BY ONSITE OR OFFSITE DISPOSAL; TREATING THE REMAINING CONTAMINATED SOIL AND POSSIBLY BEDROCK USING SOIL/BEDROCK VAPOR EXTRACTION; CONSOLIDATING THE REMAINING CONTAMINATED SOIL ONSITE WITH ANY TREATMENT RESIDUALS, FOLLOWED BY CAPPING; INCINERATING OFFSITE 8,000 GALLONS OF LIQUIDS AND SLUDGE FROM TWO REMAINING TANKS, AND DISPOSING OF THE TANKS OFFSITE; PROVIDING AN ALTERNATE WATER SUPPLY TO RESIDENTS WITH CONTAMINATED WELLS; PUMPING AND ONSITE TREATMENT OF VOC-CONTAMINATED GROUND WATER WITH DISCHARGE TO SURFACE WATER; MONITORING GROUND WATER; AND IMPLEMENTING INSTITUTIONAL CONTROLS INCLUDING DEED AND GROUND WATER USE AND RESTRICTIONS. THE ESTIMATED PRESENT WORTH COST FOR THIS REMEDIAL ACTION RANGES FROM $14,633,000 TO $16,233,000, WHICH INCLUDES AN ANNUAL O&M COST OF $908,400.

PERFORMANCE STANDARDS OR GOALS; CHEMICAL-SPECIFIC CLEANUP GOALS FOR SOIL ARE BASED ON A LIFETIME EXCESS CANCER RISK LEVEL OF 1 X (10-5). ALL WASTE AREA SOIL EXCEEDING PCBS 10 MG/KG MUST BE EXCAVATED AND TREATED. IN ADDITION, ALL SOIL EXCEEDING 10 MG/KG ABOVE BACKGROUND LEVELS USING A PHOTOIONIZATION DEVICE WILL BE EXCAVATED. ANY SOILS REMAINING AFTER EXCAVATION AND RESIDUALS LANDFILLED ONSITE MUST MEET THE SITE-SPECIFIC VOC CLEANUP STANDARDS INCLUDING BENZENE 69 UG/KG, TCE 140 UG/KG, AND PCE 1,200 UG/KG. CHEMICAL-SPECIFIC CLEANUP GOALS FOR GROUND WATER ARE BASED ON SDWA MCLS, MCLGS, AS WELL AS (10-5) EXCESS CANCER RISK CRITERIA, AND INCLUDE BENZENE 5 UG/L (MCL), PCE 5 UG/L (MCL), AND TCE 5 UG/L (MCL).
 
Remedy:  ACTUAL OR THREATENED RELEASES OF HAZARDOUS SUBSTANCES FROM THE SITE, IF NOT ADDRESSED BY IMPLEMENTING THE RESPONSE ACTION SELECTED IN THIS RECORD OF DECISION (ROD), MAY PRESENT AN IMMINENT AND SUBSTANTIAL ENDANGERMENT TO PUBLIC HEALTH, WELFARE, OR THE ENVIRONMENT. THIS REMEDY IS THE SECOND OF THREE POTENTIAL OPERABLE UNITS AT THE SITE. THE FIRST OPERABLE UNIT ROD CALLED FOR EXCAVATION AND INCINERATION OF SOIL, SLUDGE, AND OTHER WASTE MATERIALS BURIED AT THE SITE. INSTEAD, APPROXIMATELY 90 PERCENT OF THESE MATERIALS WERE EXCAVATED AND DISPOSED OF IN A HAZARDOUS WASTE LANDFILL WITHOUT THE CONSENT OF USEPA OR IEPA AND APPROXIMATELY 10 PERCENT REMAINS ON-SITE. HOME CARBON TREATMENT UNITS WERE PROVIDED TO RESIDENTS AFFECTED BY SITE CONTAMINATION, AND ADDITIONAL STUDIES WERE PERFORMED AT THE SITE UNDER THAT ROD. THIS SECOND OPERABLE UNIT REMEDIAL ACTION PROVIDES FOR TREATMENT OF THE PRINCIPAL THREATS POSED BY CONTAMINANTS IN WASTE AREAS, SOILS, BEDROCK, AND GROUNDWATER. REMAINING RISKS AT THE SITE ARE REDUCED BY ENGINEERING CONTROLS. A POTENTIAL THIRD OPERABLE UNIT WILL ADDRESS AN AREA OF GROUNDWATER CONTAMINATION BETWEEN THIS AND ANOTHER SUPERFUND SITE WHEN ADDITIONAL STUDIES HAVE BEEN COMPLETED TO DETERMINE THE SOURCE OF THIS CONTAMINATION.

THE MAJOR COMPONENTS OF THE SELECTED REMEDY INCLUDE;
* EXCAVATION OF SOILS AND SLUDGES IN TWO WASTE AREAS AND TREATMENT BY LOW-TEMPERATURE THERMAL STRIPPING.
* FURTHER TREATMENT OF RESIDUALS, IF NECESSARY, BY SOLIDIFICATION AND ON-SITE OR OFF-SITE DISPOSAL.
* INCINERATION OF THE LIQUIDS AND SLUDGES IN TWO TANKS REMAINING ON THE SITE AND DISPOSAL OF THE TANKS.
* PROVISION OF A PERMANENT ALTERNATE WATER SUPPLY TO RESIDENTS WITH CONTAMINATED WELLS.
* EXTRACTION AND TREATMENT OF VOC-CONTAMINATED GROUNDWATER AND DISCHARGE TO SURFACE WATER.
* TREATMENT OF REMAINING VOC-CONTAMINATED SOILS AND, IF POSSIBLE, BEDROCK BY SOIL/BEDROCK VAPOR EXTRACTION.
* CONSOLIDATION OF SOILS WITH REMAINING SVOC, PCB, AND LEAD CONTAMINATION AND COVERING THESE SOILS AND AREAS WHERE RESIDUALS ARE LANDFILLED ON-SITE WITH A RCRA SUBTITLE C COMPLIANT CAP.
* LONG TERM GROUNDWATER MONITORING.
* FENCING THE SITE AND PROVIDING, TO THE EXTENT POSSIBLE, DEED AND ACCESS RESTRICTIONS AND DEED NOTICES OR ADVISORIES FOR RESIDENCES WITH CONTAMINATED GROUNDWATER.
