Patents

W R Grace & Co is one of 63,768 beneficiaries of a long-standing federal subsidy called "patenting" that allows mining interests to purchase public land for no more than $5 an acre. Since acquiring title to the land, W R Grace & Co may have mined it, sold it, leased it, or passed it on to heirs or other corporate interests. Regardless of who owns the property now, the U.S. public has lost all rights- metals, minerals, and title - on land that was once public park or forest.

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.
