Public Notice: Proposed Plan for North Ridge Estates Operable Unit 2 in Klamath Falls, Oregon
Summary
The EPA is seeking public review and comments on the “No Further Action” remedy presented in the Proposed Plan A plan for cleaning up a Superfund site submitted by EPA and subject to public comments. for North Ridge Estates Superfund Site Operable Unit 2.
Operable Unit 2 – also known as the “Kingsley Firing Range Annex” – is a former munitions site with overlapping small arms, rockets, and disposal ranges. It is part of the larger North Ridge Estates Superfund site, located approximately 3 miles north of the city of Klamath Falls.
The site is divided into two geographically separate cleanup areas called "operable units." The Proposed Plan relates only to Operable Unit 2.
The Proposed Plan applies to all soil and contaminants evaluated by the EPA within the 2023 North Ridge Estates Remedial Investigation An investigation intended to gather the data necessary to: (1) determine the nature and extent of problems at the site; ( 2) establish cleanup criteria for the site; (3) identify preliminary alternative remedial actions; and (4) support the technical and cost analyses of the alternatives.. Contaminants of potential concern were limited to the soil which contained asbestos and heavy metals. The remaining soil throughout the site meets or is below relevant human health and ecological screening levels.
Only one preferred alternative – No Further Action – was considered for this Proposed Plan since there is no longer a basis for further remedial action.
