What is the EPA OIG?

The Office of Inspector General is an independent organization that performs audits and investigations of the EPA to detect and prevent fraud, waste and abuse. Learn more

Report Corrections

Any time the OIG corrects a report post-issuance, the report link in the listing below will be accompanied by a correction notation for a period of two weeks.

Our Audit 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. 

Audits 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.
