Additional Information About the Complaint Hotline

Anyone, including members of the public and Department employees, may file a complaint with the OIG Hotline.

We encourage you to report tips or information related to fraud, waste, abuse, misconduct, or mismanagement involving the U.S. Department of the Interior.

Please think carefully about the allegation and the information you have available that can help us determine whether there were criminal, civil, or administrative violations committed. Provide relevant and specific details that answer all the applicable questions on the Hotline Complaint Form. Without sufficient and relevant information, we may be unable to act on your allegation.

The OIG Hotline receives all allegations regarding fraud, waste, abuse, misconduct, or mismanagement involving the U.S. Department of the Interior.

Upon receipt of a specific allegation, the OIG will thoroughly review the details of your complaint. If you did not file anonymously, someone may contact you for additional information, so we may properly assess the issues. Once the complaint has been assessed, we will take any one of the following actions:

  • Initiate an OIG review, investigation, inspection, evaluation, or audit;
  • Refer the matter to the appropriate U.S. Department of the Interior bureau for appropriate review and action;
  • Refer the allegation to another Federal or State Law Enforcement Agency, including other Offices of Inspector General; or
  • Hold the matter in abeyance until further, specific details are reported which would require additional consideration.

The information you provide will be processed according to our internal policies and guidelines, and appropriate action will be taken pursuant to those policies and guidelines. The decision to initiate a review, investigation, inspection, evaluation, or audit, or otherwise, based on a Hotline complaint, is made solely by OIG.

If we initiate an OIG review, investigation, inspection, evaluation, or audit based on the information you provided, you may request information about the outcome by filing a Freedom of Information Act (FOIA) request. Due to privacy concerns, you will not generally be entitled to receive information on disciplinary or adverse action taken against specific individuals involved in an OIG investigation.

Your rights include the following:

  • Direct access to OIG. We want to hear from you if you have information or concerns relating to possible wrongdoing at DOI.
  • Confidentiality. OIG will protect the identity of complainants who request confidentiality to the maximum extent possible by law. Confidentiality for DOI employees is established by Section 7(b) of the Inspector General Act of 1978, which precludes the Inspector General from disclosing the identity of a DOI employee who reports an allegation or provides information without the employee’s consent, unless OIG determines that disclosure is unavoidable during the course of the investigation. Non-DOI employees who report allegations may also specifically request confidentiality.
  • Anonymity. Individuals who contact the OIG hotline are not required to identify themselves. We encourage you to provide us with your contact information, however, so that we can contact you for additional details if the need arises as OIG evaluates or pursues your allegations. Note that allegations with limited specificity or merit may be held in abeyance until more details are reported.

Submission of any information is voluntary, and the information you submit might be incorporated into a Privacy Act System of Records. Hotline complaints are reviewed by auditors, evaluators, and/or criminal investigators as conditions warrant, and access is limited to OIG staff assigned to the case, their supervisors and managers, and those who have a need to know on a case-by-case basis.
