Stage of Clean-up: Construction Completed
Conditions at Proposal (April 30, 2003): The Conroe Creosoting Company facility occupies 147 acres in Conroe, Texas. Conroe Creosoting Company was a wood treating facility that operated from 1946 until March 14, 1997. The facility treated lumber, railroad cross-ties, poles, and fence posts. Three wood preserving processes, pentachlorophenol (PCP) process, creosote process, and copper chromated arsenate (CCA) process, were used at the facility. The facility was closed by the Montgomery County Tax Assessor/Collector due to delinquent taxes and the county sold the company's assets at an auction. The land and waste management and process units remained property of the owners. The site is being proposed to the NPL because elevated levels of pentachlorophenol (PCP), dioxins, polycyclic aromatic hydrocarbons (PAHs), and metals have been found in on-site soils, surface water, waste drums, and surface impoundments, threatening nearby residents, wetlands, and rivers. The property has been flooded three times since 1994, sending contaminated flood waters into nearby residential homes and yards. Surface impoundments containing creosote waste currently drain off-site via drainage canals. Runoff from the site flows overland both to the east to Little Caney Creek and to the west to Stewarts Creek. In June 2001, a waste inventory listed several cylinders and tanks containing copper chromated arsenate solution, creosote sludge, pentachlorophenol solutions and solids, and tank bottoms. More...
