Mine Site Assessment, Stabilization, and Site Restoration

Mine Site Assessment, Stabilization, and Site Restoration
 
 
Herrera develops engineering options to contain and stabilize mine waste, restore habitats critical to endangered species, and limit public exposure to contaminants.

Throughout the assessment and reclamation process, we facilitate coordination between multiple stakeholders including local communities, Native American tribes, and state and federal agencies such the U.S. Environmental Protection Agency, U.S. Forest Service, U.S. Fish and Wildlife Service, and State Historic Preservation Offices. We provide site stabilization and reclamation designs and support the construction process by delineating contaminated areas, monitoring health and safety conditions, evaluating best management practices, and documenting and reporting cleanup activities. Our staff members have up to 30 years of experience performing restoration work at mine sites in Arizona, Colorado, Idaho, Montana, South Dakota, Washington, and Wyoming.
