BEGINNING IN THE LATE 1950S, WOOD PRESERVING OPERATIONS OCCURRED IN THIS AREA. THE PROCESS CONSISTED OF PRESSURE TREATING WOOD WITH CREOSOTE, PENTACHIOROPHENOL (PCP) AND PEIODICALLY, WATER SOLUBLE METAL SALT PRESERVATIVES. IN 1977, THE ST. REGIS PAPER COMPANY INSTALLED GROUNDWATER MONITORING WELLS AT THIS SITE. THE MONITORING WELLS REVEALED THE PRESENCE OF PCP, PAHS PCDD, PCDF, AND METALS. ON SEPTEMBER 21, 1984, EPA PLACED THIS SITE ON NPL. SINCE 1985, MPCA PERFORMED THE REMEDIAL INVESTIGATIONS, FEASIBILITY STUDY AND DEVELOPMENT AND IMPLEMENTATION OF THE RESPONSE ACTION PLAN TO ABATE OR MINIMIZE THE RELEASE OF HAZARDOUS SUBSTANCES FROM THE SITE. IN OCTOBER 2001, EPA PERFORMED A FIELD INVESTIGATION AT THIS SITE. IN JULY 2003, EPA ISSUED A CERCLA SECTION 106 TO RESPONDENT FOR PERFORMANCE OF REMOVAL EVALUATION AND SUPPLEMENTAL ASSESSMENT SAMPLING AT THE SITE. THE SAMPLING INDICATED VALIDATED DATA RESULTS CONFIRMING EARLIER FINDINGS OF DIOXIN OVER THE 1 PPB LEVEL IN VARIOUS LOCATIONS THROUGHOUT THE SITE. BASED UPON THE FINDINGS OF FACT, RESPONDENT SHALL PERFORM THE REMOVAL ACTIONS. RESPONDENT SHALL REIMBURSE U.S. EPA, UPON WRITTEN DEMAND, FOR ALL RESPONSE COSTS INCURRED BY THE UNITED STATES IN OVERSEEING RESPONDENT'S IMPLEMENTATION OF THE REQUIREMENTS OF THIS ORDER. VIOLATION OF ANY PROVISION OF THIS ORDER MAY SUBJECT RESPONDENT TO CIVIL PENALTIES TO $27,500 PER VIOLATION PER DAY.
