About the Hotline

Podcast: What is the EPA OIG Hotline?

The Office of Inspector General Hotline (OIG) services both the U.S. Environmental Protection Agency (EPA) and the U.S. Chemical Safety and Hazard Investigation Board (CSB). The hotline encourages suggestions for assessing the efficiency and effectiveness of agency programs. It also receives complaints of fraud, waste, abuse and mismanagement in agency programs and operations, and violations of law, regulations and policies by EPA and CSB employees, grantees, contractors and program participants. Complaints and requests may be submitted by anyone, including EPA and CSB employees, participants in EPA and CSB programs, Congress, organizations and members of the public. While resources restrict the OIG from pursuing every allegation, reviews relating to the following topics, known or suspected, are prioritized:

  • Efficiency and effectiveness of agency programs.
  • EPA and CSB-related criminal activity.
  • EPA and CSB contract, procurement and grant fraud.
  • Mismanagement and waste of EPA and CSB resources, including in environmental programs.
  • Theft and misuse of EPA, CSB and other government property.
  • Misconduct by EPA and CSB employees.
  • Threats in the EPA and CSB workplaces, including specific threats to federal employees.
  • EPA and CSB computer crimes.
  • Matters of high public, EPA, CSB or congressional interest.
  • Matters implicating high-level officials, for example, political or Senior Executive Service employees.

Upon receipt of a suggestion, allegation or request, the OIG may take any one of the following actions:

  1. Initiate an OIG investigation or audit.
  2. Refer the matter to EPA management for appropriate review and action.
  3. Refer the allegation to the EPA’s Scientific Integrity Officer for appropriate review and action.
  4. Refer the allegation to another federal agency, including the Federal Bureau of Investigation.
  5. Determine that the OIG will not pursue any action or make any referral.
