What's Happening?
Work has commenced on the largest Superfund project in the Silver Bow Corridor, focusing on the 30-acre Diggings East site south of George Street. This site, previously an unpermitted municipal landfill and recreation area, is undergoing extensive cleanup.
Approximately 400,000 cubic yards of tailings, wastes, and contaminated soils are being excavated. The project involves removing 240,000 cubic yards of dry material, followed by 160,000 cubic yards of wet material. Atlantic Richfield is funding the project under a consent decree finalized in 2020, with EPA approval. The cleanup is expected to take 4 to 5 years, after which the area will be transformed into a public green space, similar in design to the Shiloh Conservation District in Billings. Temporary traffic lights are in place at Kaw Avenue and George Street, and a haul route is established along Montana and Excelsior Streets to the Butte Mine Wastes Repository.
Why It's Important?
This Superfund project is critically important for the health and safety of the Butte community and the environment. The removal of 400,000 cubic yards of contaminated material will significantly mitigate environmental hazards, improving air and water quality in the Silver Bow Creek area. The transformation of a former landfill into a public green space will provide valuable recreational amenities, enhancing the quality of life for residents and making the community more livable. This project also represents a major step in fulfilling the long-term environmental remediation goals for Butte, addressing historical mining contamination. The substantial investment by Atlantic Richfield and oversight by the EPA underscore the commitment to environmental justice and restoration in affected areas.
What's Next?
The excavation of contaminated materials will continue, with plans to remove 240,000 cubic yards of dry material and 160,000 cubic yards of wet material. The project is expected to last 4 to 5 years, with Atlantic Richfield and the Butte-Silver Bow director of reclamation and environmental services, Eric Hassler, optimistic about continuous work through the winter. Following the cleanup, the site will be converted into a public green space, designed to offer recreational amenities. Other sites, including Buffalo Gulch, Blacktail Creek Riparian Areas, Butte Reduction Works, and Northside Tailings, are also slated for reclamation in the coming years, indicating a sustained effort in environmental restoration across the region.
Beyond the Headlines
The Diggings East Superfund project highlights the complex legacy of industrial activity and its environmental consequences, particularly in historical mining towns like Butte. The transformation from a contaminated site to a vibrant green space symbolizes a broader shift towards environmental stewardship and sustainable community development. This project not only addresses immediate health risks but also aims to restore ecological balance and provide a natural amenity that can foster community well-being and connection to nature. The long-term success of such initiatives depends on ongoing monitoring and maintenance, ensuring that the benefits of remediation are sustained for future generations. It also serves as a case study for other communities grappling with similar environmental challenges, demonstrating the potential for large-scale restoration through collaborative efforts.
