Current Site Status
The Davis Timber Company site includes the area where Davis Timber Company operated a wood preserving facility from 1972 until the late 1980s. EPA placed the site on the National Priorities List (NPL) in 2000 because of contaminated ground water, soil and sediment resulting from facility operations. EPA and the Mississippi Department of Environmental Quality (MDEQ) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. Site contamination does not currently threaten people living and working near the site. By cleaning up the site, EPA and MDEQ continue to protect people and the environment from site contamination.
The 30-acre site is located on Jackson Road, approximately six miles northwest of Hattiesburg in Lamar County, Mississippi. Areas of dirt, gravel and asphalt as well as grass and dense vegetation cover the site. Tree bark and wood chips cover a large portion of the site. A power line borders the site to the north, a recreational trail borders the site to the south, Jacksonville Road borders the site to the east, and a wetland and West Mineral Creek border the site to the west.
From 1972 until the late 1980s, Davis Timber Company operated a timber processing and wood preserving facility at the site. Operations included discharging wastewater into an on-site storage pond.
In 2000, EPA listed the site on the NPL. The site is not currently in use.
Site investigations found contamination in soil and sediment that could potentially harm people in the area. Contamination resulted from facility operations at the site. Contaminants of concern include dioxin and pentachlorophenol (PCP).
Contamination affected soil and sediment in East Mineral Creek. It is possible that site trespassers could encounter contaminated soil and sediment. In 1987, MDEQ issued a fish consumption ban on waters near the site. MDEQ lifted the ban in 2001.
Investigation and Cleanup Responsibility / Oversight
EPA leads site investigation and cleanup activities in cooperation with MDEQ.
Site Cleanup Plan
In 2009, EPA issued a cleanup plan (a Record of Decision or ROD) for the site. The plan included the following activities:
- Cleaning up soil and sediment contamination.
- Controlling surface water flow at the site.
- Placing institutional controls on the site property.
- Establishing a long-term monitoring program for the site’s remedy.
EPA plans to demolish all structures on the site. EPA estimates that the cleanup will take out approximately 100,000 gallons of contamination from soil for treatment to remove dissolved contaminants. The Agency estimates that the cleanup will dig up 7,600 cubic yards of contaminated soil and 3,600 cubic yards of contaminated sediment. EPA estimates that the cleanup will place a total volume of 50,000 to 60,000 cubic yards of contaminated soil and sediment in an impoundment area. EPA will then place a cap over the area and backfill and grade the area to address stormwater drainage.
The Agency also plans to move a 500-to-1,000-foot-long section of West Mineral Creek, located next to the impoundment area, approximately 200 feet farther west of its current location and construct an earthen retaining wall or berm structure between the western boundary of the impoundment area and the newly relocated portion of West Mineral Creek.
Physical remedial action construction activities began during October 2011 following receipt of remedial action funding through the President’s Jobs Initiative Program. Remedial action construction services were procured through the existing Region 4 Emergency Response and Removal Services (ERRS) contract. Construction activities were completed in September 2012, and included the following:
- Site clearing and demolition of on-site structures.
- Installation of the Impoundment liquid extraction and treatment system. This system treated approximately 525,000 gallons of liquid.
- West Mineral Creek Relocation. Relocated approximately 1,046 linear feet of creek.
- Impoundment berm construction
- Cooling pond and areas of surface soil contamination excavation. Excavated approximately 2,500 cubic yards.
- East Mineral Creek Excavation. Approximately 525 linear feet and 120 cubic yards of soil.
- Impoundment cap construction
- Final Grading and vegetation
Green Remediation Measures
The remedial action construction incorporated a number of green remediation measures through reuse, repurposing, and recycling of materials and onboard design optimization measures, including:
- Recycling of 325,200-lb of steel recovered during demolition of site structures;
- Repurposing clean concrete slab material into 3,000 cubic yards of rip rap for erosion protection in the re-aligned reach of West Mineral Creek;
- Reuse of trees and shrubs collected from site clearing and grubbing for 2,000 cubic yards of mulch;
- Optimization of the re-seeding design to incorporate drought tolerant indigenous species and soil amendments reducing the watering requirement by 30 - 35%; and,
- Reuse of treated Impoundment water for irrigation of re-seeded areas.
EPA has been unable to identify any viable potentially responsible parties for the site. EPA is using federal funds for site cleanup activities.
EPA is working with the community and its state partner to develop a long-term cleanup plan for the site, reflecting the Agency’s commitment to safe, healthy communities and environmental protection. Community engagement and public outreach are core components of EPA program activities.
EPA is conducting a range of community involvement activities to solicit community input and to make sure the public remains informed about site activities throughout the cleanup process. Outreach efforts include public notices and information meetings. EPA also held a public comment period to accept input on the cleanup plan.
In December 2011, EPA hosted an open house to share information about upcoming cleanup activities at the site.
EPA will implement institutional controls, including land use restrictions and deed notices, for the capped area and the site property to limit future land uses. Following cleanup activities, EPA will implement a long-term monitoring program to make sure the remedy remains protective of people and the environment.
EPA keeps additional site documents and information in a site information repository at the location below. EPA also posts site documents, when available, on EPA’s CERCLIS Site Profile page. For documents not available on the website, please contact the Region 4 Freedom of Information Office.
