Osborne Landfill

U.S. EPA Announces the Proposed Remedial Action Plan for the Osborne Landfill Superfund Site

Pine Township, Mercer County, Pennsylvania

On August 6, 1997, EPA issued the Proposed Remedial Action Plan (Proposed Plan) for the Osborne Landfill Site (the site) located in Pine Township, Mercer County, Pennsylvania. The Proposed Plan presents the clean-up alternatives EPA reviewed to address contaminated ground water and wetland sediment at the site and highlights EPA's preferred alternative.

Since concerns at the site are complex, EPA has addressed the cleanup in several components, called operable units (OUs). There are five OUs for the Osborne Landfill Site: OU1-Fill Material in Strip Pit; OU2-Wetland Sediments; OU3-Leachate; OU4- Clarion Formation Ground Water; and OU5-Homewood, Connoquenessing, and Burgoon Formation Ground Water. EPA documented the clean-up plans for OU1 and OU3 in a previous Record of Decision (ROD). The construction work outlined in the OU1 and OU3 ROD has been completed. This Proposed Plan addresses the contamination at and EPA's preferred alternatives for OU2, OU4, and OU5, as described below.

OU2 - Wetland Sediments

No Action - EPA determined that no action is necessary for the wetland sediments because studies have shown that contamination in the sediments does not present a significant risk to the environment. Thus, EPA did not develop or evaluate any clean- up alternatives for OU2.

OU4 - Clarion Formation Ground Water

Alternative CM2, Natural Attenuation with Monitoring - As contamination in the Clarion Formation is naturally attenuating (decreasing), EPA would conduct regular monitoring activities to ensure that contaminant concentrations continue to decrease.

OU5 - Homewood, Connoquenessing, and Burgoon Formation Ground Water

Alternative HCB2, Natural Attenuation with Monitoring - As contamination in the Homewood, Connoquenessing, and Burgoon Formations is naturally attenuating, EPA would conduct regular monitoring activities to ensure that contaminant concentrations continue to decrease.

EPA relies on community involvement when making decisions about the site, to ensure that the selected remedy addresses the concerns of the community. Beginning August 6, 1997, and ending September 4, 1997, the community can comment to EPA on the Proposed Plan and EPA's preferred alternative. During the comment period, EPA will hold a public meeting to present the Proposed Plan and to answer questions and address concerns. The public meeting will be held at 7:00 p.m. on August 25, 1997, at the East Main Presbyterian Church Fellowship Hall, 120 East Main Street, Grove City, PA 16127.

EPA will summarize and address all comments received at the public meeting and written comments postmarked by September 4, 1997, in the Responsiveness Summary section of the Record of Decision. The Record of Decision documents EPA's final selection of a clean-up plan for the site and will be publicly available. The Proposed Plan currently is available in the Administrative Record File, which is located at the:
