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 address impacted soils identified at the site. The primary objective of this removal action is to address impacted areas at the site and arrange for the disposal of PCP-contaminated soils from the former wood treating operations. Crews mobilized on June 8 to continue work on Removal Action RV001 and prepare for soil removal actions.
