ritari post & pole

RTE 1

The 212-acre Ritari Post & Pole site is located approximately 3.5 miles northeast of the small town of Sebeka in a rural area of Wadena County, Minnesota, The site was the location of a wood-preserving facility that operated from 1959 to 1991. The wood-preserving operation used creosote as a preservative until 1966, and following that, used pentachlorophenol (PCP) as a preservative. From 1966 to 1973, the site used a process that allowed approximately 72,000 gallons of PCP to drip from treated wood directly onto the ground. In addition, approximately 3,200 gallons of PCP-contaminated sludge were discharged directly to the ground. The site is located three-quarters of a mile from a wetland area which drains to the Cat River. Site Responsibility The Minnesota Pollution Control Agency (MPCA) is the lead agency which managed cleanup of the site and continues to oversee the site in coordination with EPA.
