The U.S. Environmental Protection Agency (EPA) Office of Inspector General (OIG) has issued a special notice to remind EPA contractors of their responsibilities regarding the prevention and reporting of fraud, waste, and abuse in relation to EPA contracts. Contractors are required to adhere to the Federal Acquisition Regulation (FAR) and the EPA Acquisition Regulation (EPAAR), which mandate integrity in business practices and the timely disclosure of credible evidence of legal violations. This communication is part of the OIG's initiative for 2024, designated as the "Year of Fighting Fraud," and emphasizes the importance of compliance and integrity in EPA contracting processes. Contractors are encouraged to report any suspected misconduct confidentially via the OIG Hotline or email, with the assurance of protection for whistleblowers under federal law.
