Why We Did This Report
The U.S. Environmental Protection Agency Office of Inspector General conducted this audit to determine whether the U.S. Chemical Safety and Hazard Investigation Board, or CSB, complied with the Payment Integrity Information Act of 2019, or PIIA, in fiscal year 2023.
Summary of Findings
In fiscal year 2023, the CSB complied with improper payment requirements pursuant to the PIIA. The CSB’s combined outlays for all programs totaled $8.988 million. CSB management decided to perform an improper payment risk assessment for fiscal year 2023 even though it was not required to do so, as none of its programs or activities exceeded the $10 million threshold. The risk assessment revealed no unknown payments and a gross improper payment totaling $23,651, or 0.26 percent of total outlays, in the following expense categories: payroll, lodging taxes, sales taxes, and purchases. In addition, we confirmed that the CSB completed OMB requirements to publish any applicable payment integrity information in its annual financial statement and post the annual financial statement on its website.
