Office of Inspector General


On this page:

Investigators conduct the EPA OIG’s criminal investigations, which look for violations of the law. Investigations may involve such areas as financial fraud, employee misconduct, intrusion into EPA systems and computers, impersonating EPA officials, theft of EPA property and funds, and threats and assaults against EPA employees. If a federal law is violated, the OIG presents the evidence to the U.S. Attorney’s Office, which determines if the subject(s) will be prosecuted. If the OIG’s investigation uncovers no evidence that a crime was committed, the case is closed. If the investigation finds administrative but no criminal violation, a report is given to the agency for action. 

The OIG typically does not announce, confirm or deny the existence of an open investigation or make public the results of investigations. However, once an investigation has been closed, the report of investigation (ROI) and related documents may be available under the Freedom of Information Act.

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
