[Code of Federal Regulations] [Title 43, Volume 2] [Revised as of October 1, 2004] From the U.S. Government Printing Office via GPO Access [CITE: 43CFR2091.07] [Page 54-55] TITLE 43--PUBLIC LANDS: INTERIOR CHAPTER II--BUREAU OF LAND MANAGEMENT, DEPARTMENT OF THE INTERIOR PART 2090_SPECIAL LAWS AND RULES--Table of Contents Subpart 2091_Segregation and Opening of Lands Sec. 2091.07 Principles. (a) Generally, segregated lands are not available for application, selection, sale, location, entry, claim or settlement under the public land laws, including the mining laws, but may be open to the operation of the discretionary mineral leasing laws, the material disposal laws and the Geothermal Steam Act, if so specified in the document that segregates the lands. The segregation is subject to valid existing [[Page 55]] rights and is, in most cases, for a limited period which is specified in regulations or in the document that segregates the lands. Where there is an administrative appeal or review action on an application pursuant to part 4 or other subparts of this title, the segregative period continues in effect until publication of an opening order. (b) Opening orders may be issued at any time but are required when the opening date is not specified in the document creating the segregation, or when an action is taken to terminate the segregative effect and open the lands prior to the specified opening date.
