Background

The 82-acre Penta Wood Products site is located in a predominantly agricultural area about two miles west of Siren. It operated from 1953 to 1992 using a chemical called pentachlorophenol, or PCP to treat wood posts and telephone poles. Back then, the site consisted of a main treatment building, an oil/water separator building, a gully where wastewater was discharged, a waste-water lagoon, a wood chip pile, and several other buildings, sawmills, garages and storage sheds. During its operation, wastewater containing oil and PCP was discharged into the lagoon and onto the wood chip pile. Two years after Penta Wood was closed, PCP and arsenic were found on-site in soil and ground water.

The cleanup was done in two phases. From 1994 to 1996, EPA removed about 28 storage tanks containing liquid and sludge. Also, 43,000 gallons of a PCP/oil mixture and sludge were disposed of off-site. The treatment building was demolished and contaminated soil was cleaned on-site or disposed of off-site.

By 2000, EPA had further studied the site and completed the cleanup. This included demolishing all the remaining buildings and equipment, excavating and moving contaminated soil and woodchips to an on-site disposal area, stabilizing arsenic-contaminated soil by mixing it with concrete and covering it, constructing a water-treatment system, building and infiltration and concrete basin, clearing trees and brush, installing pipes for the treatment system and ground-water extraction wells, and erecting a fence around the soil cover area.

Site Updates

Latest Update: March 2014

EPA is doing a status review of the cleanup. This type of review is required at least every five years where the cleanup is complete but hazardous waste remains managed on-site. These reviews are done to ensure that the cleanup continues to protect people and the environment. This is the third five-year review for the site. Contact the site community involvement coordinator and/or the remedial project manager to provide input on this review process.

The review will include:


• An evaluation of background information
• A summary of cleanup requirements
• A report on the effectiveness of the cleanup and any anticipated future actions
• An analysis of ways for EPA to operate more efficiently
A report, which will be available by January 2015, will detail the site's progress
