Abstract:  THE OLD MILL SITE IS IN THE VILLAGE OF ROCK CREEK, ASHTABULA COUNTY, OHIO. THE SITE CONSISTS OF TWO PARCELS OF LAND; THE HENFIELD PROPERTY AND THE KRAUS PROPERTY. LAND USE IN THE VICINITY OF THE SITE IS REPRESENTED BY A MIXTURE OF RESIDENTIAL, AGRICULTURAL, AND COMMERCIAL/INDUSTRIAL DEVELOPMENTS. THE HENFIELD PROPERTY IS APPROXIMATELY THREE ACRES, AND INCLUDES FOUR DILAPIDATED WOOD BUILDINGS AND FOUR CONCRETE SILOS. THE KRAUS PROPERTY IS APPROXIMATELY TEN ACRES, PARTIALLY COVERED WITH PILES OF RAILROAD BALLAST, AND HAS ONE EMPTY ABANDONED BULK LIQUID TANK. IN 1979, THE U.S. EPA AND OHIO EPA FOUND APPROXIMATELY 1,200 DRUMS OF TOXIC WASTE, INCLUDING SOLVENTS, OILS, RESINS AND PCBS, STORED ON BOTH THE HENFIELD AND KRAUS PROPERTIES.

SUPERFUND EMERGENCY REMOVAL ACTIVITIES AND ENFORCEMENT ACTIONS RESULTED IN DRUM REMOVAL THAT BEGAN IN NOVEMBER 1981 AND WAS COMPLETED BY OCTOBER 1982. TODAY, CONTAMINATED SOIL AND GROUND WATER REMAIN ON-SITE. THE SELECTED REMEDIAL ACTION INCLUDES; REMOVAL AND OFF-SITE DISPOSAL OF A SELECT VOLUME OF CONTAMINATED SOIL; EXTRACTION AND TREATMENT OF CONTAMINATED GROUND WATER; AQUIFER USE RESTRICTIONS; AND PROVIDING ALTERNATE WATER SUPPLY. TOTAL CAPITAL COST FOR THE SELECTED REMEDIAL ALTERNATIVE IS ESTIMATED TO BE $3,917,000 WITH O&M COSTS APPROXIMATELY $45,000 PER YEAR.
 
Remedy:  - REMOVAL AND OFF-SITE DISPOSAL OF 95 PERCENT OF CONTAMINANTS IN SOIL
- CONSTITUTES REMOVAL TO LEVELS WHICH ARE ADEQUATE TO PROTECT PUBLIC HEALTH AND THE ENVIRONMENT (4,300 CUBIC YARDS).
