Abstract:  THE FISHER CALO CHEM SITE IS IN LAPORTE COUNTY, INDIANA. THE SITE IS COMPRISED OF THE 33-ACRE ONE-LINE ROAD FACILITY, THE 340-ACRE TWO-LINE ROAD FACILITY, AND THE 170-ACRE SPACE LEASING FACILITY. SURROUNDING THE SITE ARE WOODLANDS, GRASSLANDS, WETLANDS, AND A WILDLIFE AREA. SITE CONTAMINATION AT ALL THREE FACILITIES IS THE RESULT OF THE PRODUCTION AND DISTRIBUTION OF INDUSTRIAL CHEMICALS, AND RECLAMATION OF WASTE PAINT AND METAL FINISHING SOLVENTS. FROM 1970 TO 1985, PACKAGING AND STORAGE VIOLATIONS WERE DOCUMENTED BY THE STATE DURING INVESTIGATIONS. IN 1979 WHEN THE STATE EXCAVATED BURIED DRUMS FROM THE ONE-LINE ROAD FACILITY, ADDITIONAL ONSITE CONTAMINATION WAS IDENTIFIED. IN 1982, EPA INITIATED SITE INVESTIGATIONS THAT REVEALED ELEVATED LEVELS OF ORGANIC COMPOUNDS IN GROUND WATER, HEAVY METALS IN THE SOIL, AND EVIDENCE OF ADDITIONAL BURIED DRUMS. SAMPLING AND ANALYSIS CONTINUED UNTIL 1988, WHEN EPA INITIATED A REMOVAL ACTION TO DISPOSE OF DRUMS, TANKS, CONTAINERS AT THE TWO-LINE ROAD FACILITY. THIS RECORD OF DECISION ADDRESSES THE REMAINING CONTAMINATED AREAS INCLUDING THE SOIL, WASTE MATERIAL AND STRUCTURES AT THE SITE, AND CONTAMINATED GROUND WATER IN AQUIFERS UNDERLYING THE SITE. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE SOIL, DEBRIS, AND GROUND WATER ARE VOCS INCLUDING TCE, TOLUENE, XYLENES; OTHER ORGANICS INCLUDING PAHS AND PCBS; AND ASBESTOS.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES EXCAVATION AND INCINERATION OF SEMI-VOLATILE AND PCB-CONTAMINATED SOIL, WITH ASH DISPOSAL LOCATION TO BE DETERMINED UPON LEACHING TEST RESULTS; TREATMENT OF VOC-CONTAMINATED SOIL REMAINING IN THE EXCAVATED AREA USING SOIL FLUSHING OR VAPOR EXTRACTION; LIMITED ASBESTOS REMOVAL/REPAIR OF STRUCTURES AND OFFSITE DISPOSAL OF ANY ASBESTOS-CONTAINING MATERIALS, DRUMS, TANKS, OR CONTAINERS AND THEIR CONTENTS; SEDIMENTATION BASIN, GRANULAR ACTIVATED CARBON, AND AIR STRIPPING, FOLLOWED BY FILTRATION AND REINJECTION OF THE TREATED WATER INTO THE SHALLOW AQUIFER TO ENHANCE SOIL GROUND WATER MONITORING; AND IMPLEMENTATION OF SITE ACCESS RESTRICTIONS. THE ESTIMATED PRESENT WORTH COST FOR THIS REMEDIAL ACTION IS $31,685,000, WHICH INCLUDES AN ANNUAL O&M COST OF $9,379.000.

PERFORMANCE STANDARDS OR GOALS; EXCAVATION LEVELS FOR CONTAMINATED SOIL ARE BASED ON TSCA STANDARDS AND TBC CRITERIA, INCLUDING PCBS 10 MG/KG. GROUND WATER CLEANUP LEVELS ARE DERIVED FROM ACTION LEVELS ADOPTED BY THE STATE FROM SDWA MCLS AND MCLGS, INCLUDING TCE 5 UG/L.
 
Remedy:  THIS FINAL REMEDY INCLUDES TREATMENT OF THE PRINCIPAL THREATS POSED BY THE SITE BY (1) EXCAVATION AND ON-SITE INCINERATION OF THE GROUNDWATER SOURCE AND PCB AREAS; (2) GROUNDWATER COLLECTION, TREATMENT AND REINJECTION; (3) INSTALLATION OF A NEW WATER SUPPLY WELL; (4) AN ASSESSMENT AND LIMITED REMOVAL/REPAIR OF EXISTING ASBESTOS CONTAINING STRUCTURES; AND (5) SOIL GAS TESTING, TEST PITS AND APPROPRIATE FOLLOW-UP OF SPACE LEASING AND KINGSBURY INDUSTRIAL DEVELOPMENT PARK (KIDP) PROPERTIES.

THE MAJOR COMPONENTS OF THE SELECTED REMEDY INCLUDE;

* INSTALLATION OF SECURITY FENCES AROUND THE ONE-LINE ROAD PROPERTY AND THE NATIONAL PACKAGING PROPERTY AND AN UPGRADED SECURITY FENCE AROUND THE TWO-LINE ROAD PROPERTY (SEE FIGURE).
* EXCAVATION AND INCINERATION OF SOILS CONTAINING SEMIVOLATILES AND PCBS ABOVE ESTABLISHED CLEANUP LEVELS.
* SOIL FLUSHING OR, IF PROVEN EFFECTIVE, SOIL VAPOR EXTRACTION FOR VOLATILE ORGANIC COMPOUND (VOC)-CONTAMINATED SOILS WHICH REMAIN AFTER EXCAVATION. THESE SOILS WOULD BE TREATED UNTIL LEVELS OF VOCS IN SOILS ARE ACHIEVED THAT WOULD ALLOW ATTAINMENT OF ESTABLISHED GROUND WATER CLEANUP LEVELS.
* TCLP AND EP TOXICITY TESTS ON THE INCINERATION ASH RESIDUE TO DETERMINE IF THE UNTREATED ASH MAY BE DISPOSED OF ONSITE. IF THE ASH PASSES THE TCLP AND EP TOXICITY TESTS, IT MAY BE COMPACTED AND PLACED BACK ONSITE TO FILL EXCAVATION AREAS; IF THE ASH DOES NOT PASS THE TCLP AND EP TOXICITY TESTS, IT WILL BE PLACED IN A RCRA-COMPLIANT HAZARDOUS WASTE LANDFILL.
* THE INSTALLATION OF EXTRACTION WELLS TO EXTRACT ALL CONTAMINATED GROUNDWATER. FOLLOWING EXTRACTION, THE CONTAMINATED GROUNDWATER WILL BE PUMPED THROUGH A PIPE NETWORK TO A GROUNDWATER TREATMENT FACILITY. THE TREATMENT SYSTEM WILL CONSIST OF AN EQUALIZATION/SEDIMENTATION BASIN, AN AIR STRIPPER TOWER, AND A GAC COLUMN. FOLLOWING TREATMENT, WATER WILL BE REINJECTED INTO THE UNDERLYING SHALLOW AQUIFER TO FLUSH CONTAMINANTS FROM THE SOIL AS WELL AS THE GROUND WATER.
* THE INSTALLATION OF AN ADDITIONAL MONITORING WELL SYSTEM TO DETERMINE THE EFFECTIVENESS OF THE REMEDY. AN ASSOCIATED CONTINGENCY PLAN WILL BE DEVELOPED TO PROVIDE FURTHER REMEDIAL ACTION IN THE EVENT THAT THE EXTRACTION WELLS ARE NOT EFFECTIVE IN CONTAINING THE CONTAMINATED PLUMES, OR IN THE EVENT THAT DRINKING WATER OR HEALTH-BASED STANDARDS FOR ANY CONTAMINANT ARE EXCEEDED IN THE FUTURE.
* A NEW PRODUCTION WELL CAPABLE OF PRODUCING AT LEAST 500 GALLONS PER MINUTE. THIS WELL IS NEEDED TO REPLACE THE CAPACITY OF AN EXISTING PRODUCTION WELL (WELL A) PREVIOUSLY CLOSED DUE TO CONTAMINATION.
* AN ASBESTOS ASSESSMENT AND LIMITED ASBESTOS REMOVAL/REPAIR OF EXISTING STRUCTURES. ALL TRANSIT PANELS, INTACT THERMAL INSULATION, AND OTHER ASBESTOS CONTAINING MATERIALS ON BUILDING EXTERIORS WOULD BE ENCAPSULATED. UNDER AN ASBESTOS MANAGEMENT PROGRAM, ALL FRIABLE, DAMAGED ASBESTOS CONTAINING MATERIAL (ACM) WHICH IS LOCATED OUTSIDE OF SITE BUILDINGS WOULD BE DISPOSED OF IN AN ACTIVE WASTE DISPOSAL SITE IN ACCORDANCE WITH NESHAPS 40 CFR 61.156.
* A BURIED DRUM INVESTIGATION IN TWO AREAS ON THE KIDP AND SPACE LEASING PROPERTY WHERE DRUMS AND/OR CONTAINERS MAY HAVE COME TO BE LOCATED. SOIL GAS SURVEYS AND TEST PITS SHALL BE IMPLEMENTED IN THESE AREAS TO IDENTIFY POTENTIAL ORGANIC CONTAMINATION. ALL DRUMS, CONTAINERS, CONTAINER CONTENTS AND CONTAMINATED SOILS IN THE AREAS WILL BE PROPERLY DISPOSED.
* SCOPING AND REMOVAL, IF NECESSARY, OF DRUMS, TANKS AND CONTAINERS LOCATED AT THE ONE-LINE ROAD PROPERTY AND IMMEDIATELY SOUTH OF THE NATIONAL PACKAGING BUILDING.
