Mining Plans & Notices on BLM Land

Cameco Corp and its subsidiaries are some of the 3,323 mine operators on U.S. BLM lands with mining plans and notices listed as currently active in government records, operating under laws that allow mining interests to extract and sell precious metals and minerals previously held by the public. Cameco Corp may also operate mines on Forest Service lands, which are not contained in the LR2000 database that is the backbone of this website. Because the government often fails to promptly close out records for mines no longer active, active mining may be completed for some of the operations represented by plans and notices in this website. But regardless of the status of mining operations on a particular site, filings of plans and notices are indicative of mining on the property - whether past, present, or planned. Mining operations led by Cameco Corp may well have left behind permanent pollution. In 2001 mines generated 45 percent of all pollution in EPA's Toxic Release Reporting system while accounting for just 0.36 percent of all industrial facilities.

For Cameco Corp and its subsidiaries:

• Ranking among U.S. mine operators for total land encompassed by operation plans on BLM land: 16 of 3,323 U.S. mine operators.
• Land under plans exceeds total plan areas for: over 99.5% of all other operators (BLM-managed lands only)
• Mining plans include 11 notices for mines disturbing no more than five acres and 9 surface management plans for larger mines.

Source: EWG analysis of Bureau of Land Management's Land and Mineral Records 2000 (LR2000) data system. For claims, acreages are estimated based on maximum allowable size of claims. For patents, acreages are taken directly from the LR2000 database where available, and are estimated based on maximum allowable size of claim that preceded the patent where acreages are not noted in LR2000. All notices are assumed to be five acres in size, and the size of plans are calculated directly as the size of the land represented by the legal land description in the LR2000 database. The acreages we estimate through these methods would tend to overestimate the actual amount. We welcome corrections here, and would welcome a federal data management system that included the acreages involved in these important federal land transactions.
