Abstract:  THE 160-ACRE COMMUNITY OF MILL CREEK IS LOCATED IN DEERLODGE COUNTY, MONTANA, IMMEDIATELY ADJACENT TO THE ANACONDA SMELTER NPL SITE. THE COMMUNITY OF MILL CREEK HAS BEEN CONTAMINATED FOR OVER 100 YEARS WITH SMELTER EMISSIONS, FUGITIVE EMISSIONS OF FLU DUST AT THE SMELTER, AND CONTINUED FUGITIVE EMISSIONS EMANATING FROM ADJACENT HIGHLY CONTAMINATED SOILS. SETTLED FLUE EMISSIONS IN THE COMMUNITY OF MILL CREEK, FROM THE NOW DEFUNCT COPPER SMELTING OPERATION, CONTAIN ARSENIC, CADMIUM, AND LEAD. ENVIRONMENTAL TESTING OF THE COMMUNITY AND BIOLOGICAL TESTING OF PRE-SCHOOL CHILDREN, LED EPA TO CONCLUDE THAT CONTAMINATION IN THE MILL CREEK AREA POSES AN IMMINENT AND SUBSTANTIAL ENDANGERMENT TO THE HEALTH OF INDIVIDUALS RESIDING THERE. IN COMBINATION WITH FUTURE OPERABLE UNITS FOR MILL CREEK, THE GOAL OF THIS INTERIM REMEDIATION IS TO PROVIDE ADEQUATE PERMANENT PROTECTION FOR THE HEALTH OF CURRENT RESIDENTS AND INTERIM PROTECTION FOR FUTURE SHORT-TERM VISITORS TO THE AREA. THE PRIMARY CONTAMINANT OF CONCERN AT THIS SITE IS ARSENIC. CADMIUM AND LEAD ARE SECONDARY CONTAMINANTS OF CONCERN.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES; PERMANENT RELOCATION OF ALL RESIDENTS (8 HOMES) WITH TEMPORARY EROSIONAL STABILIZATION OF DISTURBED AREAS BY ESTABLISHING AND MAINTAINING A VEGETATIVE COVER; DEMOLITION, CONSOLIDATION, AND TEMPORARY ONSITE STORAGE OF DEBRIS; FENCING AND POSTING OF THE ENTIRE SITE; AND IMPLEMENTATION OF SITE ACCESS AND DEED RESTRICTIONS. THE ESTIMATED PRESENT WORTH COST FOR THIS REMEDIAL ACTION IS $300,000.
 
Remedy:  THE REMEDY FOR MILL CREEK, MONTANA SELECTED BY EPA IS THE INTERIM FIRST OPERABLE UNIT REMEDY OF PERMANENT RELOCATION OF ALL MILL CREEK RESIDENTS. FOLLOWING RELOCATION OF ALL RESIDENTS, THE AREA WILL BE TEMPORARILY STABILIZED. THE CONTAMINATED SOILS IN MILL CREEK WILL BE ADDRESSED AS PART OF THE REMEDY FOR THE ANACONDA SMELTER NPL SITE. THE CONTAMINATED DEBRIS FROM THE RELOCATION OR DEMOLITION ACTIVITIES WILL BE CONSOLIDATED AND TEMPORARILY STORED WITH SIMILAR DEBRIS ON SMELTER HILL. FINAL DISPOSITION OF THESE MATERIALS WILL BE ADDRESSED AS PART OF THE FINAL REMEDY FOR THE ANACONDA SMELTER NPL SITE. AREAS DISTURBED BY THE RELOCATION/DEMOLITION ACTIVITIES WILL BE REGRADED AND REVEGETATED. OPERATION AND MAINTENANCE REQUIREMENTS FOR THE SELECTED ALTERNATIVE WILL INCLUDE MONITORING AND MAINTENANCE OF THE VEGETATIVE COVER USED TO STABILIZE DISTURBED AREAS AND INSTALLATION AND MAINTENANCE OF A FENCE AROUND THE PERIMETER OF THE SITE.
