Landsburg Mine Cleanup

The Landsburg Mine is a former underground coal mine located just northwest of Ravensdale. The WA Dept. of Ecology Clean-Up Action Plan is awaiting comments and approval by local area residents who might possibly be affected by remedial actions. The cleanup approach contempleted on the site includes: installation of a low-permeability soil cap, diversion of surface water, controls on land and groundwater use, monitoring of groundwater in perpetuity, and contingent groundwater treatment should contamination be detected in test wells on site. The WA Dept. of Ecology believes this approach should isolate wastes, reduce the amount of water entering and leaving the mine site, and reduce any contaminant migration.

Check this link for a Power Point presentation that provides details on all aspects of the Landsburg Mine cleanup activity. Once a cleanup action plan is finalized and approved, remedial action should take about two years to complete with compliance monitoring continuing in perpetuity.
