OIG Reports

Our Audit and Evaluation Reports

The EPA OIG conducts financial and performance audits to determine the efficiency and effectiveness of agency operations and programs. Audits identify potential fraud, waste and abuse; assess program compliance and management of agency processes; identify opportunities to improve human health and the environment; and offer recommendations for cost savings and other efficiencies.

The EPA OIG also conducts evaluations of EPA programs and activities that support clean air, clear water, safer chemicals, cleaner communities, and scientific research. The office assesses the design, implementation, and measurement of EPA programs, including evidence of program effectiveness and results.

Audits and evaluations differ from our investigations in that they do not deal with criminal activities and generally look at groups, processes, controls or structures, not individual employees. Also, when initiated, most audits are announced publicly, and upon their conclusion, a final report is posted here on the Reports page.
