The Houston Wood Treatment Plant is the location of a former wood treating business that operated from 1969 to 2013.
During wood treating operations, pentachlorophenol (PCP) was added to diesel fuel and utilized to chemically pressure-treat and preserve wood products. The Missouri Department of Natural Resources (MoDNR) referred the site to the EPA Superfund and Emergency Management Division in October 2022.
EPA conducted a removal site evaluation (RSE) in July 2023 that identified discarded, spent-PCP wood treating solutions, and PCP-contaminated soils.
A subsequent time-critical removal action conducted in January 2024 to address the abandoned and spent wood treating solutions and sludge. The primary objective of this time-critical removal action is to address the PCP-contaminated soils.
