What We Do

Since 1980, the program has safeguarded over 6,000 hazardous openings and reclaimed 1,539 acres of abandoned mined land statewide.

The major program activity is to identify the hazards and environmental problems arising from abandoned mines, design appropriate closure methods and reclamation techniques for project sites, and reclaim or safeguard abandoned mine hazards and environmental problems with the landowner’s consent. Project activities include: field investigations, project development, project design, realty work, historical and cultural resource evaluation, wildlife considerations, NEPA compliance, construction contract bidding and management, site construction and reclamation, construction inspection, and site monitoring and maintenance of prior project work.
