HIGHWAY 105 EAST, BOX 9

The Conroe Site is a former wood - treating facility located at 1776 E. Davis Street, Conroe, Montgomery County, Texas . The former wood - treating facility occupies approximately 147 acres and operated from 1946 until March 1997. The Site is fenced and borders residential property to the east, State Highway 105 to the south, and forested land to the west and north. T he facility consisted of two process areas, one tank area, two kilns, a re - work area, a vehicle maintenance shop, boiler, lumber shed, a pole machine, two fuel pumps, an office, a sales office, and a retail office along with several storage sheds and storage areas prior to a removal action conducted by the . Three wood preserving processes were used at the facility, including pentachlorophenol (PCP), creosote, and copper chromated arsenate (CCA). The PCP and creosote wood preserving processes used pressure to force a solution of PCP or creosote dissolved in diesel into the wood. The CCA treatment process is water based and occurs at ambient pressures. The treated wood was then allowed to dry on a drip pad. Treatment residues from these processes were scraped from the drying pad for shipment off - site. The facility was closed down by the Montgomery County Tax Assessor/Collector in March 1997, due to delinquent taxes. In September 2002, the EPA started a time - critical removal action of on - site structures and soils. All the contaminated mate rial, soils, sediments, and solidified wastes were placed inside an on - site Resource Conservation Recovery Act (RCRA) vault. A total of 252,000 cubic yards of contaminated material was placed inside the vault . The Record of Decision (ROD), signed on September 29, 2003, set forth the selected remedy for the site, which includes monitored natural attenuation of the contaminants in the ground water , no further action for the on - site soils and offsite sediments, long - term maintenance of the RCRA vault, and placement of institutional controls.
