Eleven (11) abandoned mine land (AML) hazards located on BLM land in Pershing County, Nevada, are to be closed. This is a joint project between the BLM and the NDOM. Cultural resource inspections have been conducted at each of the sites by the Great Basin Institute. The Nevada Department of Wildlife conducted biological surveys at each of the sites in March 2012. Bat surveys indicated a need for bat compatible closures for up to seven (7) of the eleven (11) locations. The remaining four (4) sites would be closed permanently by backfilling with waste rock materials and/or foam closure. For this project, NDOM has identified the types of hazards in two categories: 1) Adits/Inclines/Declines, and 2) Shafts. The identified hazards associated with each type are as follows:
1) Adits/Inclines/Declines: PE-0629, PE-0691, PE-0692, PE-0694, PE-0783, PE-0786, PE-0787, PE-0804 (8 total)
2) Shafts: PE-0630, PE-0690, PE-0693 (3 total)
Total AML Closures: 11
All closure work would be completed by NDOM and their contractor, Environmental Protection Services. Existing access roads would be used. Where no roads access the sites, materials would be brought in via helicopter. Closures would occur over the next several months depending on weather conditions.
