Abstract:  THE 440-ACRE AVTEX FIBERS SITE IS A FORMER SYNTHETIC FIBERS MANUFACTURING FACILITY IN FRONT ROYAL, WARREN COUNTY, VIRGINIA. THE SITE IS BOUNDED BY THE SOUTH FORK OF THE SHENANDOAH RIVER TO THE WEST AND NORTHWEST, AND BY RESIDENTIAL AREAS TO THE SOUTH, NORTHEAST, AND EAST. A SECTION OF THE SITE LIES WITHIN THE 100-YEAR SHENANDOAH RIVER FLOODPLAIN. THE PLANT PRODUCED RAYON (1940-1989), POLYESTER (1970-1977), AND POLYPROPYLENE FIBERS (1985-1989). UNTIL 1983, THE BY-PRODUCTS, INCLUDING SODIUM CELLULOSE XANTHATE-BASED VISCOSE WASTE AND ZINC HYDROXIDE SLUDGE, WERE DISPOSED OF ONSITE IN UNLINED SURFACE IMPOUNDMENTS OR LANDFILLS. SUBSEQUENTLY, THE WASTE WAS ROUTED TO AN ONSITE WASTEWATER TREATMENT FACILITY. FLY ASH (FROM INCINERATOR EXHAUST AIR POLLUTION CONTROL DEVICES) AND BOILER HOUSE SOLIDS WERE DISPOSED OF IN FOUR OTHER SURFACE IMPOUNDMENTS AND ONE FLY ASH WASTE PILE. IN 1982, A STATE INVESTIGATION IDENTIFIED CARBON DISULFIDE, A CONSTITUENT OF VISCOSE WASTE, IN RESIDENTIAL WELLS LOCATED ACROSS THE RIVER FROM THE PLANT. IN 1983 AND 1984, IN RESPONSE TO THE RESULT OF THIS INVESTIGATION, AVTEX IMPLEMENTED INTERIM MEASURES TO ADDRESS THIS GROUND WATER CONTAMINATION BY PURCHASING 23 SUBDIVISION PROPERTIES IN THE AREA WITH CONTAMINATED GROUND WATER, PROVIDING AN ALTERNATE WATER SUPPLY TO PERMANENT RESIDENTS, AND IMPLEMENTING A GROUND WATER PUMPING AND TREATMENT PROGRAM. A 1988 RECORD OF DECISION (ROD) ADDRESSED FURTHER REMEDIATION OF GROUND WATER AND DEWATERING OF 3 ONSITE VISCOSE BASIN SURFACE IMPOUNDMENTS. IN 1989, STATE SITE INVESTIGATIONS IDENTIFIED PCB CONTAMINATION IN THE SOIL AND IN SHENANDOAH RIVER FISH. THIS CONTAMINATION MAY HAVE BEEN THE RESULT OF A TRANSFORMER EXPLOSION, GENERAL MAINTENANCE PRACTICES WITHIN THE FACILITY'S POLYESTER DRYING AREA, AND SUBSEQUENT DISCHARGE OF PCB-CONTAMINATED WASTE WATER FROM THE PLANT'S SEWER SYSTEM TO THE SHENANDOAH RIVER. IN OCTOBER 1989, EPA ISSUED AN ADMINISTRATIVE ORDER (AO) TO THE SITE OWNERS, AVTEX FIBERS INC., REQUIRING PCB CLEANUP AND IDENTIFICATION AND DISPOSAL OF DRUMMED WASTES PRESENT ONSITE. THE STATE REVOKED THE PLANT'S NPDES PERMIT, AND AVTEX SUBSEQUENTLY CEASED OPERATIONS. IN 1989, EPA INITIATED A REMOVAL ACTION TO STABILIZE THE DRUMMED WASTES. IN 1990, EPA ISSUED ANOTHER AO AND THE FORMER SITE OWNERS TOOK OVER THE MAINTENANCE OF FREEBOARD IN SULFATE BASINS AND THE CONTINUATION OF WASTEWATER TREATMENT ONSITE. THIS ROD ADDRESSES THE REMOVAL OF PCB-CONTAMINATED SOIL, BREAKDOWN OF THE ACID RECLAMATION FACILITY, AND THE DISPOSAL OF DRUMMED WASTES THOUGHT TO CONTAIN OILS, BASES, ACIDS, SOLVENTS, AND PCBS. ALSO, THIS ROD ADDRESSES SITE SECURITY, CONTROL, MAINTENANCE, AND HEALTH AND SAFETY MEASURES. A SUBSEQUENT ROD WILL ADDRESS POSSIBLE REMEDIATION OF REMAINING CONTAMINATION OF ONSITE STRUCTURES, SURFACE WATER, SEDIMENTS, GROUND WATER, SEWER SYSTEM, AND WASTE DISPOSAL AREAS. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING SOIL AND DEBRIS ARE ORGANICS INCLUDING PCBS.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES EXCAVATION AND OFFSITE DISPOSAL OF APPROXIMATELY 5,000 CUBIC YARDS OF SOIL CONTAMINATED WITH PCB LEVELS EXCEEDING 10 MG/KG, FOLLOWED BY RESTORATION OF EXCAVATED AREAS; IDENTIFICATION OF DRUM CONTENTS, TREATMENT AND OFFSITE DISPOSAL OF DRUM CONTENTS THAT ARE RCRA WASTES; DECONTAMINATING AND RECYCLING OR CRUSHING THE EMPTY DRUMS FOLLOWED BY INCINERATION OR DISPOSAL IN A RCRA LANDFILL; DISMANTLEMENT OF THE UNSTABLE ACID RECLAMATION FACILITY WITH DECONTAMINATION, AS NECESSARY; AND DISPOSING OF UNUSABLE RUBBLE AND MACHINERY ONSITE. DRUMS CONTAINING NONHAZARDOUS SUBSTANCES WILL REMAIN ONSITE AND AVAILABLE FOR LIQUIDATION BY THE CORPORATE TRUSTEE UPON EPA'S APPROVAL. THE FOURTH COMPONENT OF THIS ROD IS SITE SECURITY, MAINTENANCE, CONTROL, AND HEALTH AND SAFETY MEASURES. THE ESTIMATED CAPITAL COST FOR THIS REMEDIAL ACTION IS $8,708,400. THERE ARE NO O&M COSTS ASSOCIATED WITH THIS REMEDY.

PERFORMANCE STANDARDS OR GOALS: CLEANUP LEVELS FOR PCB-CONTAMINATED SOIL ARE BASED ON EPA PUBLISHED GUIDANCE ON "REMEDIAL ACTIONS FOR SUPERFUND SITES WITH PCB CONTAMINATION." THE RECOMMENDED ACTION LEVEL FOR INDUSTRIAL LAND USE SOIL IS PCB 10-25 MG/KG. FOR THIS SITE, ALL SOIL IN EXCESS OF 10 MG/KG OF PCB WILL BE REMOVED.
 
Remedy:  THIS REMEDY IS OPERABLE UNIT TWO (OU 2) IN THE REMEDIATION PROCESS OF THE AVTEX FIBERS-FRONT ROYAL SITE. THIS REMEDY ADDRESSES PROBLEMS AND RISKS ASSOCIATED WITH DRUMMED WASTES, PCB-CONTAMINATED SOILS, THE ACID RECLAIM FACILITY, AND SITE SECURITY, CONTROL, MAINTENANCE, AND HEALTH AND SAFETY. THE OBJECTIVE OF THIS REMEDY IS TO REMOVE HAZARDOUS SUBSTANCES IN DRUMS, FROM CONTAMINATED SOILS, FROM THE FACILITY STRUCTURE AND ASSOCIATED EQUIPMENT, AND FROM OTHER SAFETY HAZARDS AND OBSTACLES TO FUTURE SITE WORK. WHILE THE REMEDY DOES ADDRESS SOME OF THE PRINCIPAL THREATS AT THE SITE, FUTURE ACTIONS WILL INVOLVE CONTINUED STUDY AND POSSIBLE REMEDIATION OF ADDITIONAL SITE STRUCTURES, GROUND WATER, SURFACE WATER, A SEWER SYSTEM, AND WASTE DISPOSAL AREAS ASSOCIATED WITH THE SITE. REMEDIAL ALTERNATIVES WHICH ADDRESS OTHER AREAS OF CONCERN WILL BE DELINEATED IN FUTURE RECORDS OF DECISION.

THE MAJOR COMPONENTS OF THE SELECTED REMEDY INCLUDE;

* IDENTIFICATION, TRANSPORTATION AND DISPOSAL OF THE 2,879 DRUMS CURRENTLY ONSITE. UPON IDENTIFICATION OF DRUM CONTENTS, LIQUID HAZARDOUS WASTES WILL BE TREATED AT AN OFFSITE TREATMENT FACILITY. THE CONTRACTOR PROCURED FOR THIS ACTION WILL BE RESPONSIBLE FOR THE ULTIMATE DISPOSAL AND/OR DESTRUCTION OF THE EMPTY DRUMS. OPTIONS FOR EMPTY DRUMS WILL LIKELY INCLUDE DECONTAMINATION AND RECYCLING, CRUSHING AND DISPOSAL IN A SECURE RCRA LANDFILL, OR INCINERATION. DRUMS WHICH CONTAIN NON-HAZARDOUS SUBSTANCES WILL BE LEFT ONSITE AND AVAILABLE FOR LIQUIDATION BY THE CORPORATE TRUSTEE UPON EPA'S APPROVAL.

* EXCAVATION, TRANSPORTATION, AND DISPOSAL OF AN ESTIMATED 5,000 CUBIC YARDS OF PCB-CONTAMINATED SOILS TO AN OFFSITE APPROVED CHEMICAL WASTE LANDFILL. SOILS CONTAMINATED WITH PCBS IN EXCESS OF 10 PARTS PER MILLION WILL BE EXCAVATED FOR DISPOSAL. FOLLOWING REMOVAL OF SOILS, THE EXCAVATED AREA WILL BE RESAMPLED TO CONFIRM THAT THE CLEANUP LEVEL HAS BEEN MET. THE EXCAVATED AREA WILL BE RESTORED AS NECESSARY WHICH MAY INCLUDE GRADING AND/OR SEEDING.

* DISMANTLING AND DEMOLITION OF THE UNSTABLE ACID RECLAIM FACILITY. BOTH THE BUILDING AND EQUIPMENT WITHIN THE BUILDING, TO THE EXTENT PRACTICABLE AND NECESSARY, WILL BE DECONTAMINATED USING BEST MANAGEMENT PRACTICES. DECONTAMINATED USABLE EQUIPMENT FROM WITHIN THE BUILDING MAY BE LIQUIDATED FOR FINANCIAL PURPOSES BY THE CORPORATE BANKRUPTCY TRUSTEE UPON APPROVAL BY EPA. THE CORPORATE TRUSTEE MAY ALSO SELL OTHER FACILITY COMPONENTS AS SCRAP OR RECYCLABLE MATERIAL UPON APPROVAL BY EPA. DECONTAMINATED BUILDING RUBBLE, DEBRIS, AND ANY UNSOLD OR RECYCLED FACILITY COMPONENTS WILL BE LEFT ONSITE. A FINAL DETERMINATION FOR MATERIALS LEFT ONSITE WILL BE MADE IN A FUTURE RECORD OF DECISION.

* CONTINUED SITE SECURITY, CONTROL, MAINTENANCE, AND HEALTH AND SAFETY MEASURES TO ENSURE PROTECTION OF HUMAN HEALTH AND THE ENVIRONMENT.
