Interior Office of Inspector General Information

Regulating energy development; conserving land and water resources; protecting wildlife; conducting scientific research; preserving national parks, monuments, and heritage areas; and addressing American Indian concerns. These diverse activities and more are the responsibility of the U.S. Department of the Interior (DOI). The mission of the Office of Inspector General (OIG) is to provide independent oversight and promote excellence, integrity, and accountability within the programs, operations, and management of the U.S. Department of the Interior. We are a highly motivated organization of about 265 employees conducting independent oversight and responding in the best interest of American taxpayers to ensure that DOI earns the public’s trust. We are alert to waste, fraud, and mismanagement, whether expressed as administrative waste or criminal activity, and we use a range of audit and investigative tools to ensure that the Secretary of the Interior, Congress, and the public are informed when changes to DOI programs become necessary to achieve this goal.
