Site Background:
The Green River Disposal Site is a 14-acre municipal/industrial waste landfill. Between 1970 and 1984, wastes from various industries and businesses were buried at the facility. 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.

Cleanup Progress: Construction Completed
The Potentially Responsible Parties (PRPs), under an Administrative Order on Consent, completed a remedial investigation/feasibility study in the summer of 1994. In December 1994, EPA selected a remedy for the Site that included capping the landfill, collecting and treating leachate, and excavation of contaminated sediment (Operable Unit 1).
Under a Unilateral Administrative Order (UAO), ten PRPs designed and implemented the remedy. Construction of the landfill cap, leachate collection system and sediment removal, was completed in October 1997.

A supplemental groundwater study was completed in 1999 to determine the condition of the groundwater and the need for treatment. EPA issued a Record of Decision (ROD) for groundwater (Operable Unit 2) on August 23, 2000. This final ROD for the site requires property restrictions (Institutional Controls (ICs)) prohibiting installation of groundwater supply wells and prohibiting disturbance of the landfill cap.  The ROD also requires continued operation and maintenance of the landfill cover system, including analysis of groundwater and leachate samples.  Two Five-Year Review reports were issued by EPA in September 2001, and September 2006.  Both reports concluded that the site remedy is operational and functional and that the site remains protective of human health and the environment.  Long-term protection of the site will be achieved when the institutional controls are established.  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.
