Significantly Disturbed For Purposes of Mineral Extraction Law and Legal Definition

According to 36 CFR 9.2, [Title 36 Parks, Forests, and Public Property; Chapter I National Park Service, Department of the Interior; Part 9 Minerals Management; Subpart A Mining And Mining Claims] Land will be considered significantly disturbed for purposes of mineral extraction when there has been surface extraction of commercial amounts of a mineral, or significant amounts of overburden or spoil have been displaced due to the extraction of commercial amounts of a mineral. Extraction of commercial amounts is defined as the removal of ore from a claim in the normal course of business of extraction for processing or marketing. It does not encompass the removal of ore for purposes of testing, experimentation, examination or preproduction activities.
