The EPA has introduced the next phase of its organizational restructuring aimed at enhancing its ability to deliver clean air, water, and land while more closely integrating scientific expertise into regulatory operations.

EPA Administrator Lee Zeldin outlined the changes in a statement highlighting structural reforms intended to improve transparency, operational efficiency, and science-based decision-making across key program offices.

Among the updates is the formation of a new Office of Applied Science and Environmental Solutions, designed to embed scientific staff into program offices and strengthen the role of research in policy development. EPA is also creating a new Office of State Air Partnerships within the Office of Air and Radiation to improve collaboration with state and tribal permitting agencies.

In the Office of Chemical Safety and Pollution Prevention, more than 130 technical experts will be added to address backlogs in chemical and pesticide reviews. Additional realignments in the Office of Water will prioritize current issues such as cybersecurity, water reuse, and emergency response.

The agency estimates that these changes, along with previous cost-cutting measures, will yield significant taxpayer savings by fiscal year 2026 while positioning EPA to better meet its statutory obligations.
