The Bureau of Indian Affairs is asking the public about the organization of a new tribe in California.
The Pinoleville Pomo Nation is already on the list of federally-recognized tribes. But a group of people on the reservation want to organize under the provisions of the Indian Reorganization Act.
"The BIA Pacific Regional Director has received a request for an administrative determination as to whether the requesting group of people is eligible to organize as a tribe under IRA," the agency said in a notice that will be published in the Federal Register on Thursday.
Tribes can secure federal recognition in a number of ways -- the BIA's administrative process or an act of Congress have been the most common methods in the last 40 years. But the IRA, which became law in 1934, also authorizes a process for groups of people of at least "one-half or more" Indian blood to organize as a tribe.
The Tejon Tribe and the Jamul Indian Village, both in California, each organized as a "community of half-bloods" by citing the law. The Tejon Tribe was placed on the list of federally-recognized entities by the Obama administration while the Jamul Indian Village organized in 1981.
