Abstract:  THE UNION SCRAP IRON METAL SITE IS A VACANT INDUSTRIAL PROPERTY IN MINNEAPOLIS, HENNEPIN COUNTY, MINNESOTA. THE SITE OVERLIES AN ALLUVIAL AQUIFER. SURROUNDING LAND USE IS PRIMARILY INDUSTRIAL AND COMMERCIAL, WITH ADJACENT RESIDENTIAL AREAS. FROM THE EARLY 1970S UNTIL 1983, THE SITE WAS USED AS A PROCESSING FACILITY FOR USED BATTERIES AND SCRAP METAL. BATTERIES WERE CRUSHED AND RECYCLABLE MATERIALS WERE SORTED. SEVERAL PILES OF CRUSHED BATTERY CASINGS AND ELECTRICAL EQUIPMENT WERE PRESENT ONSITE AT VARIOUS TIMES. INTERMITTENT INVESTIGATIONS CONDUCTED FROM 1980 TO 1987, IDENTIFIED CONTAMINATED SOIL ONSITE AS A RESULT OF THESE PROCESSING ACTIVITIES. IN 1987, A POTENTIALLY RESPONSIBLE PARTY REMOVED 773 TONS OF BATTERY CASING MATERIAL FROM THE SITE. TWO SUBSEQUENT EPA REMOVAL ACTIONS IN 1988 INCLUDED THE EXCAVATION AND OFFSITE DISPOSAL OF ONSITE CONTAMINATED SOIL, AN UNDERGROUND STORAGE TANK, DEBRIS, A CONCRETE PAD AND AN ONSITE BUILDING. A 1989 TO 1990 REMEDIAL INVESTIGATION DETERMINED THAT PRIOR REMOVAL ACTIONS WERE EFFECTIVE IN ELIMINATING CONTAMINATED ONSITE SOIL AND WASTE, AND THE LOW LEVEL GROUND WATER CONTAMINATION DOES NOT POSE ANY THREAT TO PUBLIC HEALTH. THEREFORE, THERE ARE NO CONTAMINANTS OF CONCERN AFFECTING THIS SITE.

THE SELECTED REMEDIAL ACTION FOR THIS SITE IS NO FURTHER ACTION. PREVIOUS SITE REMOVAL ACTIVITIES HAVE REDUCED ONSITE CONTAMINANT LEVELS TO BELOW BACKGROUND OR EPA HEALTH-BASED LEVELS.

PERFORMANCE STANDARDS OR GOALS: NOT APPLICABLE.
 
Remedy:  THE RESULTS OF THE REMEDIAL INVESTIGATION (RI) SHOW THAT THE EXCAVATIONS CONDUCTED BY THE EPA IN 1988 WERE EFFECTIVE IN REMOVING CONTAMINATED SOIL AND THAT THERE IS NOT A SIGNIFICANT SOURCE OR AMOUNT OF CONTAMINATED SOIL AT THE SITE. CONCENTRATIONS OF CONTAMINANTS FOUND IN THE GROUND WATER, THAT ORIGINATE AT THE SITE, ARE BELOW ANY APPLICABLE OR RELEVANT AND APPROPRIATE REQUIREMENT (ARAR'S) AND DO NOT POSE SIGNIFICANT HEALTH OR ENVIRONMENTAL RISKS. THE SELECTED REMEDY IS THAT "NO FURTHER ACTION" BE TAKEN BY THE MINNESOTA POLLUTION CONTROL AGENCY. (MPCA) SITE RESPONSE SECTION AND THE EPA OFFICE OF SUPERFUND AT THE SITE. CONTAMINANTS FOUND TO BE ORIGINATING FROM OFF-SITE SOURCES WILL BE FOLLOWED UP BY THE MPCA'S UNDERGROUND STORAGE TANK (UST) PROGRAM AND PRELIMINARY ASSESSMENT/SITE INSPECTION PROGRAM.
