Abstract:  THE 35-ACRE FORT WAYNE SITE (FW) IS A FORMER MUNICIPAL LANDFILL/WASTE DISPOSAL FACILITY LOCATED ALONG THE MAUMEE RIVER JUST EAST OF THE CITY OF FORT WAYNE, ALLEN COUNTY, INDIANA. TWO ONSITE AREAS ARE DESIGNATED AS WETLANDS. IN ADDITION, THE SITE LIES WITHIN A 100-YEAR FLOOD PLAIN. THE PRIMARY LAND USE IN THE GENERAL AREA IS LIGHT INDUSTRIAL AND COMMERCIAL. IN ADDITION, OTHER LANDFILLS, A WASTEWATER TREATMENT PLANT, AND SLUDGE DRYING BEDS ARE LOCATED ALONG THE MAUMEE RIVER IN THE VICINITY OF THE SITE. TWO RESIDENTIAL COMMUNITIES ARE LOCATED APPROXIMATELY ONE-HALF MILE FROM THE SITE. BEFORE 1967, THE SITE WAS UNCULTIVATED FARMLAND OFTEN USED FOR THE DUMPING OF UNKNOWN WASTE. THE SITE ACCEPTED RESIDENTIAL AND INDUSTRIAL WASTES FROM 1967 TO 1976. FEW RECORDS WERE KEPT ON THE VOLUME AND COMPOSITION OF WASTES, OR ON THE INDUSTRIES THAT GENERATED THE WASTES. FROM MAY 1967 TO AUGUST 1970, FW WAS ISSUED A COUNTY PERMIT FOR PUBLIC DISPOSAL OF GARBAGE AND RUBBISH. WASTES WERE INCINERATED AND THE RESIDUAL ASH DISPOSED OF ONSITE. IN 1970, FW CHANGED ITS NAME TO NATIONAL RECYCLING CORPORATION (NRC) AND BUILT A RECYCLING PLANT WHICH APPARENTLY BECAME INACTIVE AFTER FEBRUARY 1975. ALL SOLID WASTE WAS TO BE PROCESSED THROUGH THE PLANT. IT WAS TORN DOWN IN 1985. INSPECTION REPORTS INDICATED THAT DEPOSITED REFUSE INCLUDED: INDUSTRIAL AND LIQUID WASTES, MUNICIPAL WASTES, GARBAGE, PAPER, AND WOOD. A 40 TO 60 FOOT DIAMETER PIT ADJACENT TO THE MAUMEE RIVER CONTAINED POOLS OF VOLATILE LIQUIDS. WASTES WERE DISPOSED OF INTO THE PIT BY CUTTING OFF THE DRUM TOPS AND EMPTYING THE CONTENTS INTO THE PIT. THERE WERE NO RECORDS INDICATING EXACTLY WHAT WAS DUMPED INTO THE PIT. NRC OPERATION BECAME PART OF SERVICE CORPORATION AMERICA (SCA) IN 1973. IN 1974, SCA WAS DENIED A MUNICIPAL REFUSE PERMIT DUE TO SITE CLOSURE PROBLEMS ENCOUNTERED FOLLOWING HIGH WATER LEVELS. HAZARD RANKING SYSTEM RECORDS INDICATE THE ENTIRE SITE'S WASTE QUANTITY WAS EQUIVALENT TO 2,820 FIFTY-GALLON BARRELS. IN 1984,WASTE MANAGEMENT INC. (WMI) ACQUIRED SCA AND CONDUCTED AN INITIAL SITE INVESTIGATION. THE SITE HAS BEEN INACTIVE SINCE 1976. THE SITE CONSISTS OF TWO CHARACTERISTICALLY DIFFERENT AREAS REFLECTING ITS HISTORICAL USE; THE EASTERN HALF OF THE SITE WAS USED AS THE MUNICIPAL/GENERAL REFUSE LANDFILL (APPROXIMATELY 15 ACRES), AND THE WESTERN HALF OF THE SITE (APPROXIMATELY 5 ACRES) WAS USED FOR DISPOSAL OF INDUSTRIAL WASTES, BUILDING DEBRIS, BARRELS OF UNIDENTIFIED WASTES, AND RESIDUAL ASH FROM EARLIER INCINERATION OPERATIONS. PRESENTLY, SOIL AND GROUND WATER ARE CONTAMINATED WITH 43 CHEMICALS OF CONCERN INCLUDING; METALS, ORGANICS, PCBS, PAHS, PHENOLS, AND VOCS.

THE SELECTED REMEDIAL ACTION FOR THE EASTERN PORTION OF THE SITE INCLUDES; DEED AND ACCESS RESTRICTIONS; SOIL CAPPING CONSISTENT WITH STATE SOLID WASTE CLOSURE REQUIREMENTS; AND LONG-TERM GROUND WATER MONITORING. THE SELECTED REMEDIAL ACTION FOR THE WESTERN PORTION INCLUDES; EXCAVATION, RECONSOLIDATION, AND ON OR OFFSITE INCINERATION OF APPROXIMATELY MEASURES FOR THE PORTIONS OF THE SITE WITHIN THE 100-YEAR FLOODPLAIN; AND COMPENSATION FOR ANY LOSS OF WETLANDS DUE TO REMEDY CONSTRUCTION BY ENHANCING ONSITE WETLANDS. THE ESTIMATED PRESENT WORTH COST FOR THIS REMEDIAL ACTION IS $10,020,000.
 
Remedy:  THIS FINAL REMEDY ADDRESSES THE CONTAMINATION PRESENT AT THE SITE BY ELIMINATING, REDUCING OR CONTROLLING THE RISKS POSED BY THE SITE THROUGH TREATMENT, AND ENGINEERING AND INSTITUTIONAL CONTROLS.
THE MAJOR COMPONENTS OF THE SELECTED REMEDY INCLUDE:
* EXCAVATE THE AREA DEFINED AS AREA C IN THE WESTERN PORTION OF THE SITE TO REMOVE AN ESTIMATED 4,600 DRUMS CONTAINING LIQUIDS.
* INCINERATE DRUM CONTENTS.
* RECONSOLIDATE THE SOILS AND WASTE EXCAVATED DURING THE DRUM REMOVAL.
* INSTALL AND MAINTAIN A GROUNDWATER COLLECTION SYSTEM ON THE WESTERN PORTION OF THE SITE TO PROTECT THE MAUMEE RIVER FROM THE MIGRATION OF CONTAMINATED GROUNDWATER INTO THE MAUMEE RIVER AT UNPROTECTIVE LEVELS.
* PROVIDE FOR THE REMOVAL OF CONTAMINANTS FROM THE COLLECTED GROUNDWATER THROUGH TREATMENT, IF NECESSARY.
* INSTALL AND MAINTAIN A SOIL COVER COMPLIANT WITH THE "HYBRID" CLOSURE REQUIREMENTS OUTLINED IN THE RECORD OF DECISION SUMMARY ON THE WESTERN PORTION OF THE SITE.
* INSTALL AND MAINTAIN A SOIL COVER COMPLIANT WITH INDIANA SUBTITLE D - SOLID WASTE LANDFILL CLOSURE REQUIREMENTS OVER THE EASTERN PORTION OF THE SITE TO PREVENT EROSION THAT COULD RESULT IN A DIRECT CONTACT THREAT, OR WASHOUT OF THE WASTES INTO THE MAUMEE RIVER.
* MONITOR GROUNDWATER ON THE EASTERN PORTION OF THE SITE TO ENSURE THAT ANY CONTAMINANTS PRESENT DO NOT POSE A THREAT TO THE MAUMEE RIVER IN THE FUTURE.
* INSTALL AND MAINTAIN A FENCE AROUND THE SITE, EXCEPT ALONG THE RIVER, TO PROTECT THE SOIL COVERS AND RESTRICT PUBLIC ACCESS TO THE SITE.
* LIMIT BOTH PRESENT AND FUTURE USE OF THE SITE AND LIMIT THE INSTALLATION OF WELLS ON THE SITE, THROUGH DEED RESTRICTIONS.
* PROVIDE AND MAINTAIN FLOOD PROTECTION MEASURES FOR THAT PORTION OF THE SITE WITHIN THE 100-YEAR FLOODPLAIN.
* COMPENSATE FOR ANY LOSS OF WETLANDS DUE TO REMEDY CONSTRUCTION BY ENHANCING AN ON-SITE WETLAND.
