  1. Lakeside Project Utah Abandoned Mine Reclamation Program Division of Oil, Gas & Mining Department of Natural Resources

  2. Purpose : To seal hazardous abandoned mines

  3. Abandoned Mine Hazards • Roof collapse • Unstable side walls • Total darkness – you can easily get lost • Hidden vertical shafts inside • Toxic gases • Lack of oxygen

  4. Project would close: • 14 portals • 19 shafts • Affect <5 acres

  5. 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)

  6. Legal Authority • Utah has primacy under the Surface Mining Control and Reclamation Act of 1977, SMCRA

  7. Project Costs • Funded by a tax on current coal production

  8. Project Selection • Ranking priority system considers: • Population: Resident and Transient • Mining Districts: historic mining areas • Mine density • Roads and accessibility

  9. Project Schedule • Work would occur in late summer/fall of 2008 • Work would require 4 weeks

  10. Some of the laws we comply with: • National Environmental Policy Act NEPA • National Historic Preservation Act • Antiquities Act • Endangered Species Act

  11. 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

  12. Surveys & Data Collection • Abandoned Mine Inventory • Cultural & Historical Surveys • Bat Surveys • Paleontological Surveys (not applicable for Lakeside Project)

  13. Abandoned Mine Inventory

  14. Historical and Cultural Inventory House Foundation

  15. Bat Surveys

  16. Paleontological Survey

  17. AMRP’s Intent • Cause the least amount of disturbance possible • Design mine closures so that historical features are preserved • Revegetate all areas disturbed

  18. Mine Closure Designs

  19. Hand Backfill

  20. Equipment Backfill -before & after

  21. Equipment Backfill – before & after

  22. Equipment tracks raked & seeded

  23. Bat Gates Locked steel gates allow for access and bat usage

  24. Pinned Grate – before & after

  25. Pinned Grate – before & after

  26. Shaft Grate - Concrete Grade Beam

  27. Block Wall – before & after

  28. Block Wall – before & after

  29. Stone Wall – before & after

  30. Stone Wall – before & after

  31. Closure # Avg. Costs • Machine Backfill 21 <$10/CY • Hand Backfill 5 ~$100/CY • Block Wall 1 ~$40/SF • Stone Wall 0 ~$40/SF • Bat Gate 1 ~$75/SF • Grade Beam Grate 1 ~$50/SF • Pinned Grate 4 ~$45/SF • PUF 0 ~$450/CY • Compound Custom 0 varies
