Update on I-90 Dips, SF CDA River Turbidity Plumes
EPA has been monitoring unexpected turbidity plumes in the South Fork of the CDA River, north and west of Kellogg. The turbidity plumes appear to be occurring near a segment of the groundwater cut-off wall. In February, a section of Interstate 90 that runs past the Central Impoundment Area construction near milepost 48.6 began to subside, or dip, across both eastbound and westbound lanes. Dips in this section of the freeway have been occurring for several decades. Idaho Transportation Department leveled out the freeway by adding layers of asphalt to the depressions and has continued to monitor the subsidence. EPA is working closely with the State of Idaho and the Army Corps of Engineers to investigate groundwater dynamics near the site of the I-90 subsidence. We’re drilling new monitoring and extraction wells, which are expected to offer more and better data about local groundwater dynamics and what may be impacting the Interstate. As we learn more, we’ll continue to share updates on this web page and EPA’s CDA Basin Facebook page.
Bunker Hill Superfund Site Redevelopment Study Available
EPA’s study, “Reuse and the Benefit to Community: Bunker Hill Mining and Metallurgical Complex Superfund site (PDF) (17pp,3.5MB),” has just been released. The study highlights some successful commercial and recreational reuse projects on the site, including the Silver Mountain Resort, the Trail of the Coeur d’Alenes, Galena Ridge Golf Course, and more. The community assets created around the cleanup site show how the local economy can grow and thrive while active cleanup construction is ongoing.
Lower Basin Community Meeting Summary
EPA held a community meeting June 13, 2018 in Medimont, Idaho. The meeting was hosted by the Citizens Coordinating Council of the Basin Environmental Improvement Project Commission. It focused on EPA’s planning process for doing cleanup in the Lower Basin. The Lower Basin is the area along the Coeur d’Alene River valley, stretching from Enaville to Harrison. Lead and other heavy metals are of concern in the area. EPA expects to ramp up cleanup projects in the Lower Basin over the next few years.

EPA Issues Lower Basin Strategic Plan
The plan lays out the requirements, goals and objectives that guide the strategy for cleanup of the Lower Coeur d’Alene River Basin. The plan builds on information collected since the Record of Decision was signed, and lessons learned from previous cleanup actions in the Lower Basin and the Upper Basin.

Public Participation Opportunities
Thank you for your interest in the Bunker Hill Superfund Site/Coeur d'Alene Basin Cleanup. Public participation opportunities will be posted here as they become available.
We invite you to participate in quarterly meetings of the Basin Environmental Improvement Project Commission and its Citizen Coordinating Council. See "Community Groups." Also, stay tuned for public comment opportunities and community open houses and workshops.
EPA Region 10's community engagement program is designed to give people meaningful opportunities to be involved in and informed about the Coeur d'Alene Basin Cleanup. Many of our community involvement activities are done in partnership with others, including the Idaho Department of Environmental Quality, Panhandle Health District, and Coeur d'Alene Tribe. Find recent outreach documents and information about local community groups below.
Basin Bulletin newsletter - March 2019 (PDF) (10 pp, 2.62 MB) is published three times per year and covers our cleanup activities in the Coeur d'Alene Basin.
Learn about how the EPA informs and involves communities in the Coeur d'Alene Basin Cleanup in the Community Involvement Plan (PDF), updated October 2014. Ideas from residents, local groups, and community organizations helped shape this plan.
Updated September 2017, Healthy Living in the Silver Valley and Coeur d’Alene Basin (PDF) offers practical tips for limiting exposure to lead and other metals while enjoying the beautiful local environment.
Thank you to everyone who provided comments on the proposal for rebuilding the old SVNRT waste repository! The rebuilt repository will be called the Canyon Complex Repository. See Rebuilding an Old Waste Repository in the Canyon Creek Area: EPA Response to Public Comments (PDF)

Response to Community Comments Available for Old Waste Repository in the Canyon Creek Area
Thank you to everyone who took the time to provide comments on the two design options proposed for rebuilding the old SVNRT waste repository. EPA plans to reconstruct the repository to address leaking contaminants, and for future waste disposal from high priority Canyon Creek mine and mill site cleanups. After carefully considering comments, EPA has selected Option 2. We based this decision on community input and a number of design considerations. The rebuilt repository will be called the Canyon Complex Repository. See the document below to view EPA's response to concerns and questions raised by community members.

Recreational Sites Strategy
Thank you to everyone who took the time to review and provide comments on the proposed Coeur d’Alene Basin Recreational Sites Strategy. The strategy lays out a foundation for reducing health risks from lead and other metals at recreation areas. Your participation is helping us create a sensible approach that reflects local needs and values.

EPA Five-Year Review of Coeur d’Alene Basin Cleanup
We’ve completed our fourth Five-Year Review (PDF) (310 pp, 16.5MB) of the site. We are required to review sites at least every five years where contaminants remain in place. The review ensures that cleanup actions continue to protect human health and the environment, and identifies any issues and recommendations. The Five-Year Review is a comprehensive summary of the work completed to date and evaluation of the data associated with this work. When the review began a year ago, we asked the public and key stakeholders to share information and ideas about the site that could assist us with the review and ensure we had the most up-to-date and complete information about the site. For many areas cleanup actions are complete, and the current review confirmed that the cleanup measures continue to be protective. In other areas, cleanup actions are either planned or ongoing and are expected to be protective when completed. The Five-Year Review Report explains the results of the review for all areas. Find the report and supporting documents at select local libraries.
