For years, some mining operators did not reclaim land, creating environmental, health, and safety risks. Beginning in 1981, federal regulations required all operators to reclaim BLM land disturbed by these operations. In 2001, federal regulations began requiring operators to provide financial assurances before they began exploration or mining operations. GAO was asked to determine the (1) types, amount, and coverage of financial assurances operators currently use; (2) extent to which financial assurance providers and others have paid to reclaim land not reclaimed by the operator since BLM began requiring financial assurances; and (3) reliability and sufficiency of BLM's automated information system (LR2000) for managing financial assurances for hardrock operations. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-05-377/html/GAOREPORTS-GAO-05-377.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-05-377/pdf/GAOREPORTS-GAO-05-377.pdf GAO-05-377 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-05-377 Other Written Product GAO-05-377; Hardrock Mining: BLM Needs to Better Manage Financial Assurances to Guarantee Coverage of Reclamation Costs; Data integrity Federal regulations Financial analysis Financial management Information systems Land management Land reclamation Mine safety Mining Mining legislation Systems evaluation Volume 41 Page 437 41 Stat. 437 Volume 69 Page 367 69 Stat. 367 Title 43 Part 3809 43 CFR Part 3809
