[Code of Federal Regulations] [Title 20, Volume 3] [Revised as of April 1, 2003] From the U.S. Government Printing Office via GPO Access [CITE: 20CFR646.510] [Page 412] TITLE 20--EMPLOYEES' BENEFITS CHAPTER V--EMPLOYMENT AND TRAINING ADMINISTRATION, DEPARTMENT OF LABOR PART 646--PROVISIONS GOVERNING THE INDIAN AND NATIVE AMERICAN WELFARE-TO-WORK GRANT PROGRAM--Table of Contents Subpart E--Tribal Service Areas and Populations Sec. 646.510 Are there any special service area provisions made for Indians residing in Oklahoma? Yes. With the exception of the Osage reservation in Oklahoma, service areas will be determined by reference to the ``tribal jurisdiction statistical areas'' (TJSAs). TJSAs are defined by the Bureau of the Census as being areas, delineated by Federally-recognized tribes in Oklahoma without a reservation, for which the Census Bureau tabulates data. TJSAs represent areas generally containing the American Indian population over which one or more tribal governments have jurisdiction. Service areas for Oklahoma Indian residents differing from those outlined under the TJSAs may also be negotiated with the Department of Labor.
