Abstract:  THE ALSCO ANACONDA SITE IS A 4.8-ACRE FORMER SLUDGE DISPOSAL AREA IN GNADENHUTTEN, TUSCARAWAS COUNTY, OHIO. THE SITE LIES WITHIN THE TUSCARAWAS RIVER'S 50-YEAR AND 100-YEAR FLOODPLAINS AND NEIGHBORS THE ALSCO ANACONDA ALUMINUM MANUFACTURING PLANT WHICH HAS OPERATED SINCE 1948. CONTAMINATION AT THE SITE OCCURRED FROM 1965 TO 1978 WHEN WASTEWATER AND WASTEWATER TREATMENT SLUDGE FROM THE PLANT, CONTAINING HAZARDOUS ALUMINUM PROCESSING WASTES (FO19), WAS DISPOSED OF IN AN UNLINED SETTLING BASIN AND A SLUDGE PIT. IN 1978 THE PLANT OWNERS BEGAN DEWATERING THE TREATMENT SLUDGE PRIOR TO DISPOSAL OF SLUDGE OFFSITE IN THE SETTLING BASIN AND A FORMER SWAMP AREA. THIS RECORD OF DECISION (ROD) IS THE FIRST OF TWO OPERABLE UNITS AT THE SITE AND ADDRESSES REMEDIATION OF THE CONTAMINATED SOIL AND SLUDGE. BECAUSE LEACHATE FROM THE SLUDGE MAY HAVE CONTAMINATED THE GROUND WATER AND SURFACE WATER, A SUBSEQUENT ROD WILL ADDRESS THE APPROPRIATE REMEDIAL ACTION FOR THOSE MEDIA. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE SOIL AND SLUDGE ARE ORGANICS INCLUDING PCBS, AND METALS INCLUDING CHROMIUM, CYANIDE, AND ARSENIC.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES EXCAVATING 50 CUBIC YARDS OF SLUDGE CONTAMINATED WITH GREATER THAN 500 MG/KG OF PCBS FOLLOWED BY OFFSITE INCINERATION AND DISPOSAL; EXCAVATING 8,820 CUBIC YARDS OF ALUMINUM PROCESSING WASTE SLUDGE AND UNDERLYING SOIL FROM THE SETTLING BASIN AND SLUDGE PIT CONTAMINATED WITH LESS THAN 500 MG/KG OF PCBS FOLLOWED BY OFFSITE TREATMENT AND DISPOSAL OR REUSE; BACKFILLING AND REVEGETATING EXCAVATED AREAS; AND IMPLEMENTING INSTITUTIONAL CONTROLS INCLUDING SITE ACCESS AND DEED RESTRICTIONS. THE ESTIMATED CAPITAL COST FOR THIS REMEDIAL ACTION IS $4,161,066 WITH NO ASSOCIATED O&M COSTS.
 
Remedy:  THIS OPERABLE UNIT IS THE FIRST OF TWO OPERABLE UNITS PLANNED FOR THE SITE. THIS ACTION ADDRESSES THE SOURCE MATERIAL CONSISTING OF CONTAMINATED SLUDGE AND SOIL. THE SECOND PLANNED ACTIVITY WILL ADDRESS CONTAMINATED GROUND AND SURFACE WATER. THIS ACTION PROPOSED FOR THE SOURCE MATERIAL WILL CONTRIBUTE TO THE OVERALL STRATEGY FOR THE SITE AS IT WILL REMOVE AND TREAT THE PRINCIPAL DIRECT CONTACT THREAT TO HUMANS, ELIMINATE THE THREAT OF RELEASE OF CONTAMINATED MATERIAL TO THE RIVER, AND WILL NO LONGER CONTRIBUTE CONTAMINANTS TO THE GROUNDWATER.

THE MAJOR COMPONENTS OF THE SELECTED REMEDY INCLUDE;

* EXCAVATION OF APPROXIMATELY 50 CUBIC YARDS OF SLUDGE CONTAMINATED WITH GREATER THAN 500 MILLIGRAMS PER KILOGRAM (MG/KG) OF POLYCHLORINATED BIPHENYLS (PCBS) AND TRANSPORTATION OFF SITE FOR TREATMENT TO A FACILITY PERMITTED TO INCINERATE PCB WASTE; AND
* EXCAVATION OF APPROXIMATELY 8,820 CUBIC YARDS OF REMAINING SLUDGE AND UNDERLYING SOIL, WHICH INCLUDES SLUDGE CONTAMINATED WITH LESS THAN 500 MG/KG OF PCBS, TO LEVELS MEETING CLEAN CLOSURE REQUIREMENTS FOR TREATMENT AND DISPOSAL AT AN OFF-SITE FACILITY IN COMPLIANCE WITH THE CERCLA OFF-SITE POLICY (APPROVED FACILITY) OR A RECLAMATION/REUSE FACILITY.
* BACKFILL SELECTED AREAS, AND RECONTOUR AND VEGETATE ANY EXCAVATED OR CLEARED AREAS; MAINTAIN THE PRESENT SECURITY FENCE; AND NOTICE OF THE REMEDIAL ACTION RECORDED WITH THE PROPERTY DEED.
