Environmental Assessment Abandoned Mine Lands Safety Installations Multiple Mine Openings Mojave National Preserve, California

The National Park Service (NPS) proposes implementing safety options at abandoned mine lands in Mojave National Preserve. The purpose of this project is to mitigate human and environmental hazards present at the Preserve.

This action is needed to; improve visitor and staff safety at Mojave while accommodating the use of the abandoned mine land sites by wildlife (principally bats), minimize impacts on historic fabric and the visual character of the historic landscape, and minimize potential adverse effects on natural resources using mitigation measures.

The EA examines two alternatives: no action and the National Park Service (NPS) preferred alternative. The preferred alternative includes installing a variety of abandoned mine safety techniques, such as metal grates, fencing (permanent or temporary), bat gates and cupolas, cable mesh nets, foam plugs covered with backfill, or back-filling alone, in multiple mine openings at Mojave. A variety of safety techniques would be implemented by the National Park Service either individually, or in combination under alternative B.
