Wyoming AML Small Hard Rock Site Remediation

Hard rock mine sites were discovered and mined across Wyoming, dating back to the early 1800’s. After miners ceased operations at these prospects, the sites were not reclaimed, leaving behind associated hazards and risks from residual mining operations. Herrera is currently working with Wyoming Abandoned Mine Lands Division to mitigate hazards associated with these abandoned hard rock sites.

Herrera is assisting with the investigation, remediation design, and construction management of approved reclamation mine sites. Investigation includes identifying and gathering data associated with the hazard feature attributes. This data is pertinent to the eligibility determination standard set forth by the Office of Surface Mining Reclamation and Enforcement. These associated sites must also receive NEPA clearance, as well as United States Forest Service clearance. Design for these closures depends on the hazards that exists at each site, which can include dangerous high walls, tunnels, adits, mine shafts, spoil and waste piles, and historical equipment and facilities. Final construction and seeding these disturbed sites are the final elements to reduce hazards associated with these mine sites.
