What is a waste repository?
Soil from cleanups of residential and commercial properties contains metals - like lead and arsenic - that can harm people. This soil needs a place where it can be safely contained. These waste repositories are carefully chosen and engineered to securely contain contaminated soil and reduce impacts to people and the environment. Waste repositories are managed long after they are closed to be sure the contaminants remain contained and secure.
At EPA’s and IDEQ’s request, national technical and policy experts performed an "optimization review" in 2016. They reviewed water quality monitoring at the Big Creek Repository and the East Mission Flats Repository. The goal is to improve monitoring and to better understand the wider environment around the repositories. Based on the findings, EPA, with IDEQ and the CdA Trust, has approved several enhancements to the monitoring. There will now be more standardized reporting, an efficient monitoring system that includes the BCR and BCR Annex, and installation of two new monitoring wells near EMF.
Limited Use Repositories
Limited Use Repositories accept waste only from replacement of local paved roads taking place under the Coeur d'Alene Basin Cleanup.
Lower Burke Canyon Repository
The Lower Burke Canyon Repository, will be located in Wallace, east of Burke Road (Highway 4) and north of Grays Bridge Road, near Woodland Park. The site is currently a closed mine tailings impoundment. Waste material removed from cleanups within the Canyon Creek area will be placed on top of this already contaminated surface. This repository will also receive wastes from the Institutional Control Program administered by Panhandle Health District. Local residents helped select this site for a repository.
EPA has responded to the public’s comments on the repository’s design. One commenter raised issues about its height and truck traffic. Another commenter was concerned about dust from and management of the nearby SVNRT repository. To see our responses, go to this link.
East Mission Flats Repository
The East Mission Flats Repository, located west of Cataldo, Idaho, contains waste soil contaminated with metals from property cleanups in the Lower Basin.
The Page Waste Repository, located west of Smelterville, Idaho, contains waste soil contaminated with metals from development activity in the Box.
Big Creek Repository
The Big Creek Repository is located east of Kellogg, Idaho. It accepts waste from cleanups and the ICP in the Upper Basin. The existing repository site is getting full, and plans are in the works to build an add-on. The CDA Trust is now acquiring two properties just across the creek from the repository. The annex will be developed on about 9.5 acres, directly west of the existing decon-station. In 2014, we expect to design the annex, construct a small bridge, and move some water lines and a pump house owned by a nearby golf course. The annex would increase the amount of space available for storing waste removed from cleanup areas. The facilities already in place at the repository – the wash off area, the office, the entrance -- would also serve the annex. The repository annex will, for the most part, not be visible from the golf course. Contact: Bill Adams, 206-553-2806, 800-424-4372, firstname.lastname@example.org.
