Current Site Status
The Tri-City Disposal Co. includes an area where Tri-City Disposal Company operated a landfill from 1964 to 1967. EPA placed the site on the National Priorities List (NPL) in 1989 because of contaminated ground water, soil and surface water resulting from landfill operations. EPA, the Kentucky Department for Environmental Protection (KDEP) and the site’s potentially responsible parties (PRPs) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. By treating surface water and undertaking Five-Year Reviews, EPA, KDEP and the site’s PRPs continue to protect people and the environment from site contamination.
Site Location and Background
The 349-acre site is located on State Highway 1526 in Shepherdsville, Bullitt County, Kentucky. The site includes a 57-acre landfill and several residential properties. Forested land, the Brushy Fork Creek and several springs border the site. The site’s broader surroundings include rural residential areas. From 1964 to 1967, the Tri-City Disposal Company operated a landfill at the site. The company disposed of highly volatile liquid wastes, lumber scraps and fiberglass insulation materials from various Louisville area industries at the on-site landfill. Landfill operations buried drums and stored drums above ground at the site. In 1989, EPA listed the site on the NPL. A portion of the site is used for residential and agricultural purposes.
Site investigations found contamination in ground water, soil and surface water that could potentially harm people in the area. Contamination resulted from waste handling practices at the site. Contaminants of concern include volatile organic compounds (VOCs), polychlorinated biphenyls (PCBs), lead, chromium, mercury and creosote.
Contamination affected surface water in two springs on site and a tributary of the Brushy Fork Creek. Surface water flows south and enters the Brushy Fork Creek, which supports livestock, agriculture and recreational activities.
The site’s PRPs placed a fence around one of the springs to limit access.
Contamination also affected on-site soils and ground water.
Investigation and Cleanup Responsibility / Oversight
The site’s PRPs lead site cleanup activities, with oversight provided by EPA and KDEP.
Site Cleanup Plan
Site investigations and cleanup activities have focused on two areas, which EPA refers to as operable units, or OUs. These areas include OU-1: ground water contamination; and OU-2: additional measures to mitigate threats from contamination.In 1991, EPA issued a cleanup plan (a Record of Decision, or ROD) for OU-1. The plan included the following activities:
- Placing institutional controls to restrict use of contaminated ground water.
- Providing affected residents with an alternate water supply.
- Monitoring ground water, surface water, sediment and living organisms.
- Treating surface water in on-site springs if contamination is detected.
- Sampling soil to determine the effectiveness of emergency removal activities.
- Sampling of sediment and air.
- Using a carbon absorption system to treat contaminated surface water.
- Discharging treated water to a downstream tributary.
In 1996, EPA issued a cleanup plan (a ROD) for OU-2. The plan included EPA’s decision that no further cleanup activities were necessary.
In 1988, EPA began emergency response activities at the site. EPA provided nearby residents with an alternate water source. EPA also dug up and disposed of drums and contaminated soil at an off-site facility.
The site’s PRPs completed the remedial design in 1992. The PRPs completed construction of the remediation facilities in 1994 and began operating the carbon absorption system to address surface water contamination.
The PRPs placed a fence around one of the springs to limit access.
The site’s third Five-Year Review, completed in 2008, found that the cleanup continues to protect people and the environment. The Five-Year Review also recommended additional work at the site. EPA and the PRPs are following-up on the Five-Year Review recommendations by working to place institutional controls on the site property, conduct additional soil sampling and assess vapor intrusion in buildings.
EPA negotiated legal agreements with the site’s PRPs to investigate and clean up the site. The PRPs continues to fund site cleanup, monitoring and oversight activities.
EPA has worked 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 has conducted 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 have included public notices and interviews.
Cleanup activities, including treatment of surface water, are ongoing.
EPA completed the last Five-Year Review in 2008 and plans to complete the next Five-Year Review in 2013.
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.
