The Missouri Wood Treating Co. site is the location of a former wood treating business that operated from approximately 1938 to 2016. During wood treating operations, a five percent (%) pentachlorophenol (PCP) and diesel fuel mixture was utilized to chemically pressure-treat and preserve oak and pine wood products. U.S. Environmental Protection Agency (EPA) performed Compliance Sampling Inspections at the property and documented the presence of impacts to the property associated with wood treating operations. The Missouri Department of Natural Resources (MoDNR) issued a Request for Federal Action (RFA) to the U.S. Environmental Protection Agency (EPA) Superfund and Emergency Management Division on March 28, 2023 to determine if a removal action was warranted. EPA conducted a Removal Site Evaluation (RSE) in October and December 2023 which identified abandoned spent PCP wood treating solutions remaining in containers at the site and PCP-contaminated soils in areas surrounding the former operations areas.
A removal action was deemed warranted to addressed abandoned wood treating solutions. The primary objective of this removal action is to address all PCP-contaminated liquid wastes, associated sludges, and containers abandoned at the site from the wood treating operations. Crews mobilized on June 3 and consolidated wastes. Coordination is currently underway to arrange for off-site transportation and disposal of liquid wastes, which is anticipated to occur during Summer 2024.
