Site Background
The Green River Disposal Site is a 14-acre municipal/industrial waste landfill in Daviess County, Kentucky. The Green River Disposal site is the former Green River Disposal Inc. (GRDI) landfill and surrounding property. Between 1970 and 1984, various industrial wastes from nearby industries and businesses were buried at the facility. Due to the topography of the site, wastes were pushed into ravines and covered with soil. The facility had a history of leachate outbreaks and underground fires. The site held a State disposal permit from 1975 until 1988, but the facility closed in 1984. In 1985 an investigation by the State found that a private well adjacent to the site was contaminated.
The site is located in a sparsely populated area of Daviess County, Kentucky near the town of Maceo. Land use in the site area ranges from undeveloped deciduous forests, to farmland and scattered residential development. Thirty-seven residences are located within a 1-mile radius of the site.
Threats and Contaminants
Sediments are contaminated with metals, including zinc, chromium and lead. Ground water and leachate are contaminated with constituents from the landfill, including aluminum, arsenic, barium, cadmium, chromium, copper, lead, and zinc.
Site Cleanup Plan
The cleanup plan for the Green River site covers two operable units (OUs): OU-1 (soil) and OU-2 (contaminated ground water).
The Record of Decision (ROD) for OU-1 was issued in 1994. Major elements of the cleanup approach included:
- Capping the landfill (waste disposal) area with a composite barrier cover.
- Collection of the leachate with subsurface drains, and treatment by chemical and/or physical methods. Discharging treated water to a nearby stream.
- Excavation of contaminated stream and pond sediment and consolidation with the landfill waste.
- Removal of surface debris and/or buried wastes located in the east and west ravines, and dispose of these wastes within the landfill cap.
The ROD for OU-2 was issued in 200. Major elements of the cleanup approach included:
- Implementation of institutional controls to prohibit construction of any ground water wells and construction of any type of structure on the landfill cap or within 50 feet of the cap.
- Development and implementation of a ground water monitoring plan to evaluate performance of the landfill cap and leachate collection system.
Cleanup Progress
Remedial Investigation field activities were initiated in October 1991 and the combined Remedial Investigation / Feasibility Study (RI/FS) was completed in June 1994.
Cleanup activities for OU-1 began in June 1996 and were completed in October 1997. The Remedial Action Construction Report for OU-1 was submitted to EPA in January 2000 and approved in March 2000.
A supplemental ground water study was completed in 1999 to determine the condition of the ground water and the need for treatment. EPA issued a ROD to address contaminated ground through ground water monitoring and institutional controls.
Ground water monitoring is currently being performed and placement of institutional controls is pending.
Two Five-Year Reviews (FYRs) have been completed for the site, in 2001 and 2006. The 2006 FYR found that the remedy for OU-1 was protective of human health and the environment and the remedy for OU-2 would be protective once institutional controls are implemented.
Site cleanup activities are being led primarily by potentially responsible parties (PRPs) with oversight by EPA.
Enforcement Activities
An Administrative Order on Consent between EPA and four PRPs to conduct an RI/FS was signed in May 1990. In May 1995, the Administrative Order on Consent was modified to include performance of the Remedial Design by the PRPs.
Under a 1996 Unilateral Administrative Order (UAO), ten PRPs were ordered to implement the OU-1 remedy.
A 2002 Consent Decree between EPA and the PRPs set forth requirements and an implementation schedule for the OU-2 remedy.
Community Involvement
EPA has conducted a range of community involvement activities at the Green River site to solicit community input and to ensure that the public remains informed about site activities throughout the site cleanup process. Outreach activities have included public notices, interviews, and public meetings on cleanup activities and updates.
Future Work
EPA is currently coordinating with the PRPs for implementation of the institutional controls, and expects that they will be established by the Fall of 2008.
The next FYR for the site is scheduled for 2011.
