Hart Creosote, a 442-acre site located in Jasper, TX, was a wood treatment facility from 1958 until May 1993. The facility operations consisted of steam conditioning and pressure treatment of wood using creosote. These operations contaminated the soil, surface water and ground water with polynuclear aromatic hydrocarbons (PAHs), posing a threat to two public and 39 private wells used for drinking water and irrigation by approximately 8,000 people. The site has been divided into three Areas of Concern (AOC). AOC #1 is the existing onsite, capped and fenced, disposal cell, which contains approximately 75,000 cubic yards of contaminated material. AOC #2 is an unnamed tributary to Big Walnut Run Creek. AOC #3 is the Dense Non-Aqueous Phase Liquid (DNAPL) plume and any contaminated ground water.
Current Site Status and Cleanup Actions to Date
- In 1995, EPA dismantled the existing tanks, structures and equipment, removed liquid wastes and contaminated soils, drained the on-site impoundments, stabilized the remaining sludge, and consolidated the sludge and contaminated soil into an on-site waste cell. The waste cell has been fenced and warning signs have been posted. It is approximately 2.25 acres in area and contains an estimated volume of 75,000 cubic yards.
- In July 1999, the site was placed on the National Priority List (NPL).
- EPA initiated an Engineering Evaluation/Cost Analysis (EE/CA) in September 2000 to investigate contamination in the onsite waste cell (AOC #1) and unnamed tributary (AOC #2).
- In September 2001, EPA signed an action memorandum to conduct a non-time critical Removal Action for AOC #1 and AOC #2. This removal action proposes to excavate contaminated soils from AOC #1 and conduct biological treatment of the soil in a Land Treatment Unit (LTU) to be constructed onsite. Contaminated sediments in AOC #2 will be excavated to a depth not to exceed two feet and also placed into the LTU. Removal of source material from the tributary will be followed by the application of phytoremediation and in-situ constructed wetland technologies.
- EPA plans to clean up the contaminated soil through a biological treatment, remove pockets of concentrated creosote material from the unnamed tributary, and then use in-situ phytoremediation to act as a source control measure until long-term remedies are implemented.
Current Funding Status
- EPA has spent approximately $1,664,000 on work associated with the previous Removal Action, the Remedial Investigation/Feasibility Study (RI/FS) and Remedial Design (RD). However, the non-time critical Removal Action was not funded in Fiscal Year 2004. A final ROD for the site is scheduled for September 2005. After signature of the ROD, funding new work at this site will be determined.
- The EPA has determined that the site does not pose an immediate threat to human health, and will continue to monitor this site for any changes that may trigger additional action.

- EPA completed a time critical removal action at the site in September 1995 to reduce the immediate risks posed by the site.
- The site was placed on the National Priority List (NPL) in July 1999.
- EPA signed an action memorandum on September 27, 2001, to conduct a non-time critical removal action addressing Areas of Concern (AOC) #1 and #2 at the site.
- All Remedial Investigation fieldwork was completed in June 2004, and a final RI/FS report is scheduled for December 2004. The Record of Decision (ROD) for the site is scheduled for September 2005 and will address AOC #1, #2 and #3 at the site.
