inherently federal for the purposes of an ISDEAA contract or compact begins with the Office of inherently federal for the purposes of an ISDEAA contract or compact begins with the Office of 
the Solicitor or the appropriate bureau or office, which reviews the list of functions prepared by the Solicitor or the appropriate bureau or office, which reviews the list of functions prepared by 
the applicant tribe. Only after this review does DOI inform the tribe which functions are the applicant tribe. Only after this review does DOI inform the tribe which functions are 
contractible. S.O. 3377 states that since DOI’s management of energy resources on tribal lands contractible. S.O. 3377 states that since DOI’s management of energy resources on tribal lands

Thus, S.O. 3377 required the Solicitor’s Office to create two lists: one for inherently federal functions that are not contractible under a TERA and one for federal functions that are.
