25 U.S. Code § 3324 - Critical area service agreements
An Indian tribe or tribal organization may, by formal action, waive the service agreement of an Indian student for just cause, as determined in accordance with regulations prescribed by the Secretary. The tribe or organization shall notify the Secretary in writing of any waiver granted under this subsection.
The Secretary shall, by regulation, provide for the pro rata reduction of repayment obligations under subsection (a)(2) in the case of any student who partially completes the service obligation of that student under subsection (a)(2)(A).

Section 3323(b) of this title, referred to in subsec. (a)(2)(A), was in the original a reference to “section 1322(b)”, meaning section 1322(b) of Pub. L. 102–325, which has been translated as reading section 1323(b) of Pub. L. 102–325 to reflect the probable intent of Congress because section 1322 does not have a subsec. (b) and section 1323(b) relates to designation of critical areas by tribes.
