Purpose : To seal hazardous abandoned mines

Page 3: Lakeside Project

Abandoned Mine Hazards

• Roof collapse• Unstable side walls• Total darkness – you can easily get

lost• Hidden vertical shafts inside • Toxic gases• Lack of oxygen

Page 4: Lakeside Project

Project would close:

• 14 portals• 19 shafts

• Affect <5 acres

Page 5: Lakeside Project

Right of Entry (ROE)

• Permission is obtained from all land owners prior to any construction work

– Private land– Public (Bureau of Land Management)– State Trust Lands (minerals)– Private (Surface)

Page 6: Lakeside Project

Legal Authority

• Utah has primacy under the Surface Mining Control and

Reclamation Act of 1977, SMCRA

Page 7: Lakeside Project

Project Costs

• Funded by a taxon current coal production

Page 8: Lakeside Project

Project Selection

• Ranking priority system considers:

– Population: Resident and Transient– Mining Districts: historic mining areas– Mine density– Roads and accessibility

Page 9: Lakeside Project

Project Schedule• Work would occur in late summer/fall of

2008• Work would require 4 weeks

Page 10: Lakeside Project

Some of the laws we comply with:• National Environmental Policy Act

NEPA• National Historic Preservation Act• Antiquities Act• Endangered Species Act

Page 11: Lakeside Project

Environmental Assessment

• Analyzes potential impacts on the environment

• Includes clearances from:– State Historic Preservation Officer– US Fish and Wildlife Service

• Sign-offs from:– Office of Surface Mining– Bureau of Land Management

Page 12: Lakeside Project

Surveys & Data Collection

• Abandoned Mine Inventory• Cultural & Historical Surveys• Bat Surveys• Paleontological Surveys

(not applicable for Lakeside Project)

AMRP’s Intent• Cause the least amount of

disturbance possible• Design mine closures so that

historical features are preserved• Revegetate all areas disturbed
