Abstract:  FIELDS BROOK IS LOCATED IN THE CITY OF ASHTABULA, OHIO AND DRAINS A 5.6-SQUARE MILE WATERSHED (DEFINED AS THE "SITE"). THE 3.5 MILE MAIN CHANNEL OF FIELDS BROOK FLOWS THROUGH AN INDUSTRIAL AREA THAT IS ONE OF THE LARGEST AND MOST DIVERSIFIED CONCENTRATIONS OF CHEMICAL PLANTS IN OHIO. THE BROOK EMPTIES INTO THE ASHTABULA RIVER WHICH SUBSEQUENTLY FLOWS INTO LAKE ERIE 8,000 FEET DOWNSTREAM OF ITS CONFLUENCE WITH FIELDS BROOK. INDUSTRIAL SOURCES HAVE CONTAMINATED THE SEDIMENT IN FIELDS BROOK WITH A VARIETY OF ORGANIC AND HEAVY METAL POLLUTANTS, INCLUDING TCE, PCE, CHLOROBENZENE, VINYL CHLORIDE, ARSENIC, ZINC, MERCURY AND CHROMIUM. BASE-NEUTRAL COMPOUNDS INCLUDING HEXACHLOROETHANE, TOLUENEDIAMINE AND TOLUENE DIISOCYANATE ALSO HAVE BEEN DETECTED IN FIELDS BROOK SEDIMENTS. SEDIMENTS TAKEN FROM THE ASHTABULA RIVER IN THE VICINITY OF FIELDS BROOK ARE CONTAMINATED WITH PCBS. THE U.S. EPA BELIEVES THAT THE AMOUNT OF CONTAMINATION ENTERING THE BROOK AT THIS TIME HAS BEEN SUBSTANTIALLY REDUCED DUE TO THE RECENT DEVELOPMENT OF POLLUTION CONTROL LAWS AND DISCHARGE PERMITTING REQUIREMENTS.

THE SELECTED REMEDIAL ACTION FOR THE FIELDS BROOK SITE INCLUDES; PROVISIONS FOR THE EXCAVATION OF CONTAMINATED SEDIMENT FROM FIELDS BROOK, THE TEMPORARY STORAGE AND DEWATERING, AND THE THERMAL TREATMENT OF A PORTION AND THE SOLIDIFICATION AND ONSITE LANDFILLING OF THE REMAINDER. BASED ON CRITERIA PRESENTED IN THE ROD, APPROXIMATELY 36,000 CY OF CONTAMINATED SEDIMENTS WILL BE SOLIDIFIED, AND 16,000 CY WILL BE THERMALLY TREATED. THE REMEDY ALSO INCLUDES TREATMENT OF WASTE WATER FROM THE DEWATERING PROCESS, AND PROVISION OF O&M COSTS FOR ONE YEAR. THE ESTIMATED CAPITAL COST OF THE REMEDY IS $35,100,000 WITH ANNUAL O&M COSTS OF $72,000.
 
Remedy:  - PROVISIONS FOR THE EXCAVATION OF CONTAMINATED SEDIMENT FROM FIELDS BROOK, THE TEMPORARY STORAGE AND DEWATERING, AND THE THERMAL TREATMENT OF A PORTION AND THE SOLIDIFICATION AND LANDFILLING OF THE REMAINDER. THE BREAKDOWN IS BASED ON CRITERIA IN THE SUMMARY OF REMEDIAL ALTERNATIVE SELECTION. SUBSEQUENT WATER TREATMENT IS ALSO INCLUDED.
- FIRST YEAR OPERATION AND MAINTENANCE COSTS TO PROVIDE FOR LONG-TERM MONITORING AFTER THE REMEDY HAS BEEN COMPLETED.
