There is hereby established in the Treasury of the United States a Bonneville Power Administration fund (hereinafter referred to as the “fund”). The fund shall consist of (1) all receipts, collections, and recoveries of the Administrator in cash from all sources, including trust funds, (2) all proceeds derived from the sale of bonds by the Administrator, (3) any appropriations made by the Congress for the fund, and (4) the following funds which are hereby transferred to the Administrator: (i) all moneys in the special account in the Treasury established pursuant to Executive Order Numbered 8526 dated August 26, 1940, (ii) the unexpended balances in the continuing fund established by the provisions of section 832j of this title, and (iii) the unexpended balances of funds appropriated or otherwise made available for the Bonneville Power Administration. All funds transferred hereunder shall be available for expenditure by the Secretary of Energy, acting by and through the Administrator, as authorized in this chapter and any other Act relating to the Federal Columbia River transmission system, subject to such limitations as may be prescribed by any applicable appropriation act effective during such period as may elapse between their transfer and the approval by the Congress of the first subsequent annual budget program of the Administrator.
Moneys heretofore or hereafter appropriated shall be used only for the purposes for which appropriated, and moneys received by the Administrator in trust shall be used only for carrying out such trust. The provisions of chapter 91 of title 31 shall be applicable to the Administrator in the same manner as they are applied to the wholly owned Government corporations named in section 9101 of title 31, but nothing in section 9105(d)  of title 31 shall be construed as affecting the powers granted in subsection (b)(11) of this section and in sections 832a(f), 832i(b), and 832k(a) of this title.
Notwithstanding the provisions of sections 9105 and 9106 of title 31, the financial transactions of the Administrator shall be audited by the Comptroller General at such times and to such extent as the Comptroller General deems necessary, and reports of the results of each such audit shall be made to the Congress within 6½ months following the end of the fiscal year covered by the audit.
