Abstract:  AUTO ION CHEMICALS SITE IS A FORMER PLATING WASTE TREATMENT AND DISPOSAL FACILITY OCCUPYING APPROXIMATELY 1.5 ACRES OF VACANT, FENCED LAND IN KALAMAZOO, MICHIGAN. THE SITE IS BOUNDED TO THE NORTH, EAST, AND WEST BY COMMERCIAL/INDUSTRIAL FACILITIES AND LIES ADJACENT TO AND WITHIN THE FLOODPLAIN OF THE KALAMAZOO RIVER. GROUND WATER AT THE SITE IS NOT CURRENTLY USED AS A SOURCE OF DRINKING WATER. FROM 1964 TO 1973 THE FACILITY RECEIVED CHROME AND CYANIDE PLATING WASTE. HEAVY METALS WERE PRECIPITATED FROM THE PLATING WASTE AND DEPOSITED IN AN ONSITE LAGOON, AND WASTEWATER WAS DISCHARGED TO THE SANITARY SEWER. LEAKS AND SPILLS FROM STORAGE TANKS, LAGOON SEEPAGE, AND OTHER SITE ACTIVITIES RESULTED IN SOIL CONTAMINATION. IN 1983 EPA CONDUCTED AN EMERGENCY SURFACE REMOVAL AND, IN 1986, THEY DEMOLISHED THE SITE STRUCTURES WHICH HOUSED TANKS AND STORAGE FACILITIES. THIS FIRST OPERABLE UNIT REPRESENTS A SOURCE CONTROL REMEDIAL ACTION FOR THE SOIL. A SECOND OPERABLE UNIT WILL ADDRESS GROUND WATER CONTAMINATION. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE SOIL ARE ORGANICS INCLUDING PAHS; AND METALS INCLUDING ARSENIC, CHROMIUM, AND LEAD.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES EXCAVATION AND OFFSITE STABILIZATION OF APPROXIMATELY 7,200 CUBIC YARDS OF CONTAMINATED SOIL; OFFSITE DISPOSAL OF TREATED SOIL IN AN APPROVED LAND DISPOSAL AREA; AND REPLACEMENT OF THE EXCAVATED SOIL WITH CLEAN FILL. THE ESTIMATED CAPITAL COST FOR THIS REMEDIAL ACTION IS $3,332,988, WITH AN ESTIMATED ANNUAL O&M COST OF $5,900.
 
Remedy:  THIS OPERABLE UNIT IS THE FIRST OF TWO OPERABLE UNITS FOR THE SITE. THIS INITIAL OPERABLE UNIT ADDRESSES THE SOURCE OF SOIL AND GROUNDWATER CONTAMINATION. THE REMEDY ADDRESSES THE PRINCIPAL THREATS AT THE SITE BY REMOVING AND TREATING THE CONTAMINATED SOIL. TREATED SOIL WILL BE DISPOSED OF OFF-SITE. THE MAJOR COMPONENTS OF THE REMEDY INCLUDE;

* EXCAVATION AND OFF-SITE TREATMENT, VIA STABILIZATION, OF APPROXIMATELY 7200 CUBIC YARDS OF CONTAMINATED SOIL;
* DISPOSAL OF THE TREATED SOILS IN AN APPROPRIATE OFF-SITE FACILITY; AND
* REPLACEMENT OF THE EXCAVATED SOIL WITH CLEAN FILL.

A SUPPLEMENTAL RI/FS REPORT WILL BE COMPLETED TO IDENTIFY THE EXTENT OF GROUNDWATER CONTAMINATION AND TO DEVELOP AND EVALUATE APPROPRIATE REMEDIAL ALTERNATIVES.
