Abstract:  THE NL/TARACORP/GOLDEN AUTO PARTS SITE IS LOCATED IN ST. LOUIS PARK, HENNEPIN COUNTY, MINNESOTA. A SECONDARY LEAD SMELTING FACILITY OPERATED ONSITE FROM 1940 UNTIL 1982. LAND USE ADJACENT TO THE SITE IS LIGHT INDUSTRY. THERE ARE RESIDENTIAL AREAS WITHIN 0.25 MILE OF THE SITE TO THE NORTH, EAST, AND WEST. AQUIFERS BENEATH THE SITE SERVE AS PRIMARY SOURCES OF DRINKING WATER IN THE AREA, SUPPLYING 90 PERCENT OF ALL GROUND WATER USED IN THE REGION. THE SITE WAS ORIGINALLY OWNED BY NL INDUSTRIES, INC., BUT WAS LATER DIVIDED AND EACH PORTION SOLD TO A SUCCESSION OF OWNERS. ONE OF THESE OWNERS, TARACORP, OWNED AND OPERATED THE LEAD SMELTING FACILITY FROM AUGUST 1979 UNTIL FEBRUARY 1981. SECONDARY LEAD SMELTING OPERATIONS RECOVERED LEAD FROM LEAD PLATES, BATTERY FRAGMENTS, AND LEAD CONTAINERS. THE INDUSTRIAL OPERATIONS AND ONSITE WASTE DISPOSAL ACTIVITIES RESULTED IN ELEVATED LEAD LEVELS IN AIR AND ONSITE SOIL. UNDER A CONSENT ORDER, NL CONDUCTED ONSITE INVESTIGATIONS AND CLEANUP ACTIVITIES BETWEEN 1985 AND 1988 INCLUDING SOIL REMEDIATION, CAPPING THE SITE WITH ASPHALT, AND ESTABLISHING A LONG-TERM GROUND WATER MONITORING PROGRAM. AS PART OF THE CONSENT ORDER, NL WAS ALSO REQUIRED TO INVESTIGATE AND, IF NECESSARY, CLEAN UP SOIL NEAR THE SITE POSSIBLY CONTAMINATED BY WINDBLOWN CONTAMINANTS. THIS REMEDIAL ACTION ADDRESSES THE POSSIBILITY OF OFFSITE SOIL CONTAMINATION. INVESTIGATIONS INDICATE THAT OFFSITE SOIL DOES NOT CONTAIN ELEVATED LEVELS OF LEAD ATTRIBUTABLE TO THE SITE. THERE ARE NO CONTAMINANTS OF CONCERN ATTRIBUTABLE TO THE SITE AFFECTING THE OFFSITE SOIL.

THE SELECTED REMEDIAL ACTION FOR THIS SITE IS A NO ACTION REMEDY. THE ONE RESIDENTIAL YARD THAT EXCEEDS STATE AND ATSDR GUIDANCE LEVELS FOR SOIL LEAD IS NOT CLEARLY ATTRIBUTABLE TO THE SITE, BUT WILL BE ADDRESSED THROUGH A COOPERATIVE CLEANUP BY NL INDUSTRIES. THERE IS NO CAPITAL COST OR O&M ASSOCIATED WITH THIS REMEDIAL ACTION.
 
Remedy:  THIS REMEDIAL ACTION IF THE FINAL REMEDIAL ACTION FOR THE OFF-SITE SOILS PORTION OF THIS SITE. THE ON-SITE SOILS AND GROUND WATERPORTIONS OF THE NL SITE HAVE BEEN ADDRESSED BY A CONSENT ORDER FORRI/FS AND REMEDIAL ACTIONS SIGNED BY NATIONAL LEAD, THE UNITED STATES ENVIRONMENTAL PROTECTION AGENCY (U.S. EPA) AND THE MINNESOTA POLLUTION CONTROL AGENCY (MPCA) IN 1985. THE CONSENT ORDER COVERED THREE AREAS OF THE NL SITE; 1.ON-SITE SOILS INVESTIGATION, STABILIZATION, AND CLEANUP; 2.GROUND WATER INVESTIGATION AND LONG-TERM GROUND WATER MONITORING; AND 3.AN OFF-SITE SOILS REMEDIAL INVESTIGATION AND IF NECESSARY A FEASIBILITY STUDY FOR REMEDIAL ACTION. THE ON-SITE INVESTIGATION, STABILIZATION, AND CLEANUP ACTIVITIES WERE COMPLETED WITH CAPPING OF THE NL SITE IN JUNE, 1988. BASED ON THE GROUND WATER INVESTIGATION, A LONG-TERM GROUND WATER MONITORING PROGRAM WAS ESTABLISHED IN NOVEMBER, 1987. THIS RECORD OF DECISION DOCUMENTS U.S. EPA'S DECISION FOR THE ACTION TO BE TAKEN FOR THE OFF-SITE SOILS PORTION OF THE NL SITE. BASED ON THE ADMINISTRATIVE RECORD, U.S. EPA HAS DECIDED THAT NO FURTHER ACTION IS NECESSARY FOR THE OFF-SITE SOILS NEAR THE NL SITE.
