Infrastructure Investment and Jobs Act Progress Report—Year Two

Report Number

Why We Did This Report

The Infrastructure Investment and Jobs Act, or IIJA, appropriates over $60 billion to the U.S. Environmental Protection Agency from fiscal year 2022 through 2026, the largest appropriation that the Agency has ever received. This second annual IIJA progress report provides updates on our oversight of the EPA’s execution of that funding through January 31, 2024.


This report provides updates on the OIG’s IIJA-related spending and hiring efforts as well as oversight work the OIG planned, initiated, or completed during its second year of IIJA oversight. It also details the OIG’s declaration of 2024 as the “Year of Fighting Fraud” and describes ongoing outreach to help deter fraud and improve efficiency in the EPA’s IIJA programs and operations. Finally, the report discusses the OIG’s efforts to leverage data analysis to detect grant and contract fraud and provide oversight transparency.
