This bill requires the Environmental Protection Agency to commission independent, outside audits of its air pollution programs and activities every year for six years, starting within one year of the law's enactment. Each audit must follow international and government auditing standards and must examine a representative sample of grant recipients and loan recipients to track how EPA funds are being used and managed. The EPA must submit detailed reports to Congress within 180 days of each audit completion, breaking down findings by category including financial disbursements, program operations, regulation development, compliance assistance, and enforcement activities. The bill authorizes the EPA to use existing funds from its Environmental Programs and Management account to pay for these audits, meaning no new appropriations are required.
