Each recipient of Federal financial assistance under subsection (b) shall keep such records as the Secretary shall require, including records which fully disclose the amount and disposition by each recipient of the proceeds of such assistance, the total cost of the plan, program, projects, measures, or systems for which such assistance was given or used, the source and amount of funds for such plan, program, projects, measures, or systems not supplied by the Secretary, and such other records as the Secretary determines necessary to facilitate an effective audit and performance evaluation. The Secretary and Comptroller General of the United States, or any of their duly authorized representatives, shall have access for the purpose of audit and examination, at reasonable times and under reasonable conditions, to any pertinent books, documents, papers, and records of any recipient of Federal assistance under this part.
Each State receiving Federal financial assistance pursuant to this section shall provide reasonable assurance to the Secretary that it has established policies and procedures designed to assure that Federal financial assistance under this part and under part E of this subchapter will be used to supplement, and not to supplant, State and local funds, and to the extent practicable, to increase the amount of such funds that otherwise would be available, in the absence of such Federal financial assistance, for those programs set forth in the State energy conservation plan approved pursuant to subsection (b).
