As of September 2024, the U.S. Environmental Protection Agency (EPA) employed approximately 17,000 individuals, accounting for about 10.2% fewer staff than in 2010. This figure includes both permanent and temporary employees across its headquarters in Washington, D.C., and its 10 regional offices.USAFacts
However, the EPA is currently undergoing significant restructuring under Administrator Lee Zeldin, appointed in early 2025. The agency has announced plans to reduce staffing levels to those of the 1980s, which would entail substantial layoffs. Specifically, the Office of Research and Development is set to be dissolved, with its 1,500 scientists competing for 400 new positions in other departments.

These changes are part of a broader initiative to streamline the agency’s operations, align with the current administration’s policy goals, and reduce costs. Critics argue that such restructuring may compromise the EPA’s scientific independence and effectiveness in enforcing environmental protections.ReutersThe Guardian+1WIRED+1
Given these developments, the total number of EPA employees is expected to decline significantly in the near future.
