Union Pacific Railroad, Wallace-Mullan Branch, Northern ID.
Response Action Summary
The mine waste-related contamination has concentrations of lead and other heavy metals that are above levels considered safe for protection of human health and the environment. A combination of response actions are being proposed by the U.S. Environmental Protection Agency (EPA) to address this mine waste contamination. The proposed response actions have been selected from a number of alternatives that were evaluated within a document called an Engineering Evaluation/Cost Analysis (EE/CA).
The preferred response action includes installation of protective asphalt and/or vegetative barriers, removal/disposal of selected mine waste contaminated materials, and control of access and use of right of way through trail design and signage/educational efforts. Due to the variety of conditions and terrain along the right of way, the EE/CA should be consulted directly for further details about a particular location.
An electronic, text-only version of the EE/CA (excluding Figures, Tables, and Appendices) is available through this website.
