Indian tribes and tribal organizations to which grants are provided under this chapter, and tribally controlled schools for which such grants are provided, shall not be subject to any requirements, obligations, restrictions, or limitations imposed by the Bureau that would otherwise apply solely by reason of the receipt of funds provided under any law referred to in clause (i), (ii), or (iii) of subparagraph (A).
Notwithstanding section 2503(a)(2)  of this title, with respect to funds from facilities improvement and repair, alteration and renovation (major or minor), health and safety, or new construction accounts included in the grant provided under section 2503(a)  of this title, the grant recipient shall maintain a separate account for such funds.
Upon completion of a project for which a separate account is established under this paragraph, the portion of the grant related to such project may be closed out upon agreement by the grantee and the Secretary.
With respect to a grant to a tribally controlled school under this chapter for new construction or facilities improvements and repair in excess of $100,000, such grant shall be subject to the Administrative and Audit Requirements and Cost Principles for Assistance Programs contained in part 12 of title 43, Code of Federal Regulations.
In considering applications for a grant described in clause (i), the Secretary shall consider whether the Indian tribe or tribal organization involved would be deficient in ensuring that the construction projects under the proposed grant conform to applicable building standards and codes and Federal, tribal, or State health and safety standards as required under section 1124 of the Education Amendments of 1978 (25 U.S.C. 2005(a))  with respect to organizational and financial management capabilities.
Notwithstanding subparagraph (A), a school receiving a grant under this chapter for facilities improvement and repair may use such grant funds for new construction if the tribal governing body or tribal organization that submits the application for the grant provides funding for the new construction equal to at least 25 percent of the total cost of such new construction.
In a case in which the appropriations measure under which the funds described in subparagraph (A) are made available or the application submitted for the funds does not stipulate a period for the work covered by the funds, the Secretary and the grant recipient shall consult and determine such a period prior to the transfer of the funds. A period so determined may be extended upon mutual agreement of the Secretary and the grant recipient.
A tribe or organization described in subparagraph (A) may enforce its rights under subsection (a)(2) and this paragraph, including rights relating to any denial or failure to act on such tribe’s or organization’s request, pursuant to the dispute authority described in section 2508(e) 5 of this title.
