On July 18, 2025, EPA Administrator Lee Zeldin announced the largest workforce reduction in the agency's 55-year history: 3,707 employees terminated, reducing the workforce from 16,155 (January 2025) to 12,448 -- a 23% cut that returned EPA staffing to levels not seen since the Reagan administration. The agency simultaneously announced the elimination of its Office of Research and Development (ORD), the primary scientific research arm of the agency, replacing it with a subordinate "Office of Applied Science and Environmental Solutions." The reorganization was projected to save $748 million annually.
Scope of the Cuts
The July 18 announcement formalized months of rolling terminations that had already gutted EPA capacity:
The cuts fell disproportionately on scientists: up to 1,155 EPA chemists, biologists, toxicologists, and other scientists faced layoff from ORD alone, which employed 1,540 staff members before the reorganization.
Elimination of Office of Research and Development
ORD had been EPA's independent scientific research arm since the agency's creation in 1970. It conducted foundational research on air quality, water contamination, chemical toxicity, and climate science that underpinned virtually every EPA regulation. Its elimination removed the agency's capacity to independently assess environmental and health risks, making EPA dependent on industry-supplied data for regulatory decisions.
The replacement "Office of Applied Science and Environmental Solutions" embedded remaining scientists within program offices rather than maintaining an independent research capacity -- a structural change that subordinated scientific inquiry to political and regulatory priorities set by political appointees.
Reagan-Era Comparison
Zeldin explicitly framed the cuts as returning EPA to Reagan-era staffing levels. The comparison is historically loaded: the Reagan EPA under Anne Gorsuch Burford (1981-1983) was the most scandal-plagued period in EPA history, resulting in Burford's resignation under Congressional contempt charges and the criminal conviction of EPA Superfund chief Rita Lavelle for perjury. The Reagan-era EPA is widely regarded as the prototype for regulatory capture of environmental agencies.
Downstream Consequences
By September 2025, the administration was on track to cut one in three EPA staffers by year's end, with additional reductions during the October 2025 government shutdown. The cumulative effect eliminated EPA's capacity to:
Capture Significance
The EPA mass layoffs represent the most aggressive destruction of federal regulatory capacity since the agency's founding. Unlike the Reagan era, where political appointees attempted to weaken enforcement while maintaining the institutional structure, the Trump-Zeldin approach eliminated the institutional capacity itself. By destroying ORD and cutting the scientific workforce, the administration ensured that even a future administration committed to environmental protection would need years to rebuild the expertise, institutional knowledge, and research infrastructure that was dismantled in months. This is the "burn the ships" approach to deregulation: not merely capturing the regulator, but destroying its capacity to regulate.
