Abstract:  THE 85-ACRE BOFORS NOBEL SITE IS AN ACTIVE SPECIALTY CHEMICAL PRODUCTION PLANT IN EDELSTON TOWNSHIP, MUSKEGON COUNTY, MICHIGAN. AN INACTIVE LANDFILL IS ALSO LOCATED IN THE EASTERN PORTION OF THE SITE. ONSITE WETLANDS LIE WITHIN THE FLOODPLAIN OF BIG BLACK CREEK, WHICH RUNS THROUGH THE SOUTHERN PORTION OF THE SITE. THE SITE OVERLIES A LACUSTRINE AQUIFER, A POTENTIAL DRINKING WATER SOURCE, WHICH HAS BEEN CONTAMINATED AS A RESULT OF SITE ACTIVITIES. DURING THE 1960S AND EARLY 1970S, SLUDGE, WASTEWATER, AND WASTE LIQUIDS FROM PLANT OPERATIONS WERE DISCHARGED INTO 10 ONSITE LAGOONS. SUBSEQUENT INVESTIGATIONS BY EPA HAVE IDENTIFIED EIGHT OF THE ONSITE LAGOONS AS POTENTIAL SOURCES OF GROUND WATER CONTAMINATION. IN 1976, THE STATE RESTRICTED WASTEWATER DISCHARGE FROM THE SITE, AND A GROUND WATER PUMP AND TREATMENT SYSTEM WAS INSTALLED TO TREAT CONTAMINATED GROUND WATER IN THE LACUSTRINE AQUIFER. THIS RECORD OF DECISION (ROD) ADDRESSES REMEDIATION OF THE LAGOONS, AS WELL AS UPGRADING THE CURRENT GROUND WATER TREATMENT SYSTEM. A SUBSEQUENT FINAL ROD WILL ADDRESS OTHER CONTAMINATED SOIL AND COMPLETE RESTORATION OF THE AQUIFER. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE SOIL, SLUDGE, AND GROUND WATER ARE VOCS INCLUDING BENZENE.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES EXCAVATING APPROXIMATELY 101,000 CUBIC YARDS OF SLUDGE AND BERM MATERIAL HIGHLY CONTAMINATED WITH VOCS, TREATING THE CONTAMINATED MATERIAL ONSITE USING INCINERATION AND LOW TEMPERATURE THERMAL DESORPTION, DISPOSING OF THE RESIDUAL ASH IN AN ONSITE LANDFILL, AND TREATING SCRUBBER WATER FROM THE INCINERATOR BY PRECIPITATION; TREATING LANDFILL LEACHATE IN THE GROUND WATER TREATMENT SYSTEM; EXCAVATING APPROXIMATELY 372,000 CUBIC YARDS OF LESS VOC-CONTAMINATED SOIL AND SLUDGE AND DISPOSING OF THESE WASTES ONSITE IN THE LANDFILL; PUMPING AND TREATMENT OF GROUND WATER USING OZONE OXIDATION OR A COMPARABLE TREATMENT WITH ONSITE DISCHARGE TO SURFACE WATER; MONITORING GROUND WATER, SURFACE WATER, AND AIR; AND IMPLEMENTING SITE ACCESS RESTRICTIONS INCLUDING FENCING. THE ESTIMATED PRESENT WORTH COST FOR THIS REMEDIAL ACTION IS $70,874,000, WHICH INCLUDES AN ANNUAL O&M COST OF $313,000 FOR 43 YEARS.

PERFORMANCE STANDARDS OR GOALS: LANDFILLED MATERIAL MUST EXHIBIT AN EXCESS LIFETIME CANCER RISK OF LESS THAN (10-6). CHEMICAL-SPECIFIC SOIL CLEANUP LEVELS WERE DEVELOPED BASED ON THE TYPE AND LOCATION OF CONTAMINATED MEDIA WITHIN OR ADJACENT TO THE LAGOONS INCLUDING BENZENE 410 TO 4,500 UG/KG. GROUND WATER CLEANUP LEVELS ARE BASED ON PROPOSED BEST AVAILABLE TECHNOLOGY DISCHARGE STANDARDS INCLUDING BENZENE 5.0 UG/L. INSTITUTIONAL CONTROLS: NOT PROVIDED.
 
Remedy:  THIS OPERABLE UNIT IS THE FIRST OF TWO OPERABLE UNITS FOR THE SITE. THIS OPERABLE UNIT ADDRESSES CONTAMINATED SLUDGES AND SOILS IN THE LAGOON AREA, A MAJOR SOURCE OF CONTAMINATION AT THE SITE. THE SECOND OPERABLE UNIT WILL INVOLVE REMEDIATION OF CONTAMINATED SOILS IN THE VICINITY OF THE OPERATING MANUFACTURING FACILITY AND REMEDIATION OF THE CONTAMINATED GROUNDWATER. THE RESPONSE ACTION FOR THIS OPERABLE UNIT ADDRESSES THE PRINCIPAL THREAT REMAINING AT THE SITE BY TREATING THE MOST HIGHLY CONTAMINATED SLUDGE. TREATMENT RESIDUALS, LESS-CONTAMINATED SLUDGE, AND SOILS CONTAMINATED AT LOW LEVELS WILL BE DISPOSED OF IN AN ON-SITE LANDFILL THAT WILL MEET THE INTENT OF RCRA SUBTITLE C REQUIREMENTS.

THE MAJOR COMPONENTS OF THE SELECTED REMEDY INCLUDE;

* EXCAVATION AND TREATMENT, VIA ON-SITE THERMAL TREATMENT, OF APPROXIMATELY 101,000 CUBIC YARDS OF THE MOST-CONTAMINATED SLUDGE FROM THE LAGOON AREA;
* DISPOSAL OF APPROXIMATELY 19,000 CUBIC YARDS OF LESS-CONTAMINATED SLUDGE, APPROXIMATELY 353,000 CUBIC YARDS OF CONTAMINATED SOILS, AND SOLID TREATMENT RESIDUALS IN AN ON-SITE RCRA SUBTITLE C LANDFILL; AND
* UPGRADING OF EXISTING GROUNDWATER PUMPING AND TREATMENT SYSTEM.
