The Infrastructure Investment and Jobs Act appropriates over $60 billion to the U.S. Environmental Protection Agency for a wide range of environmental programs, such as water sector infrastructure, land clean up, and electric school buses. The IIJA also provides for OIG oversight of these funds.
U.S. EPA Infrastructure Investment and Jobs Act (IIJA) Spending Dashboard
The OIG has created the U.S. EPA Infrastructure Investment and Jobs Act (IIJA) Spending Dashboard below to inform the public of current EPA Obligations and Outlays for IIJA projects:
IIJA Oversight Plan
As part of this oversight, we developed an IIJA Oversight Plan, which guides our audits, evaluations, and oversight engagements to address the EPA programs receiving or impacted by IIJA funds. As the Agency refines its plans to execute the IIJA, we will continue to refine and expand our IIJA Oversight Plan.

Infrastructure Investment and Jobs Act Oversight Plan - Inaugural Edition

Our groundwork and early oversight also included identifying lessons learned from prior oversight activities; assessing program areas for risk of fraud, waste, or abuse; and initiating several new projects. The OIG has also provided IIJA fraud briefings and conducted several other outreach activities with the Agency, other OIGs with IIJA oversight responsibilities, the U.S. Government Accountability Office, and Congress.
Below is a list of our planned, ongoing, and completed IIJA oversight work. As we oversee the EPA’s implementation of the IIJA, we will update this website regularly to provide timely information on our IIJA oversight activities.
