EPA dissolves research office, scientific output drops 82% on pace

The EPA's Office of Research and Development (ORD) was established in 1970 when President Nixon created the EPA through Reorganization Plan No. 3. ORD was formed as the agency's primary independent scientific research arm, consolidating research laboratories and facilities transferred from the Department of Health, Education, and Welfare; the Interior Department; the Atomic Energy Commission; and the USDA. For 56 years, ORD conducted foundational research on lead pollution, particulate matter, ozone toxicology, and other health effects that underpin EPA air and water quality regulations. This independent structure — with career scientists insulated from direct political pressure — allowed ORD to publish inconvenient findings about pollution's actual health costs, even when those findings contradicted industry preferences.

In May 2026, EPA Administrator Lee Zeldin formally dissolved ORD and replaced it with a smaller Office of Applied Science and Environmental Solutions (OASES). The structural change removes institutional independence: where ORD operated as a separate division with career scientists, OASES is housed directly under the administrator's office. Zeldin had announced the planned dissolution in a May 2025 briefing; the Trump administration specifically called for a roughly 45% budget cut to ORD's operations, signaling that the elimination was intentional policy. Critics including the House Science Committee and EPA unions argue that moving research into the administrator's direct office makes it more susceptible to political interference and industry pressure.

EPA peer-reviewed publication output has collapsed following the reorganization and workforce reductions. Through early May 2026, EPA scientists published 61 peer-reviewed papers -- on pace for roughly 163 publications by year-end, according to data compiled by PEER (Public Employees for Environmental Responsibility). This represents a 52% annual decline from 2024, when the EPA published 339 peer-reviewed papers. The publication decline tracks the agency's workforce cuts: the EPA reduced headcount by approximately 3,000 employees between fiscal 2025 and 2026, roughly 20% of the agency's total workforce, with an estimated 25-30% of those cuts concentrated in science-related positions. Federal News Network's May 2026 reporting, based on PEER's data, showed that hundreds of EPA scientists resigned or were reassigned to non-scientific roles.

Courts have long required EPA regulations to rest on an adequate scientific record under the Administrative Procedure Act's arbitrary-and-capricious standard. In Motor Vehicle Manufacturers Ass'n v. State Farm (1983), the Supreme Court held that agencies must examine relevant data and articulate a satisfactory explanation for regulatory action, including a rational connection between facts found and choices made. An agency action can be set aside if it fails to consider relevant factors or if there is a clear error of judgment. For EPA specifically, this means the agency must demonstrate that its rules rely on sufficient scientific evidence -- weakness in EPA's scientific capacity directly weakens both new rulemaking and the legal defensibility of existing rules in court.

In Massachusetts v. EPA (2007), the Supreme Court ruled 5-4 that EPA must determine whether greenhouse gas emissions endanger public health and welfare based on science rather than policy preference. The Court rejected EPA's argument that scientific uncertainty justified regulatory inaction, holding instead that if scientific uncertainty is profound, EPA must say so explicitly -- not use uncertainty as cover for avoiding a reasoned decision. This precedent obligates EPA to make science-based endangerment findings, which requires ongoing independent research capacity. Weakened research capacity means EPA's future endangerment determinations rest on thinner evidence, making them vulnerable to industry legal challenges.

The shift from ORD to OASES embodies regulatory capture concerns. Regulatory capture occurs when an industry regulated by an agency gains disproportionate influence over that agency's decisions and operations. An ORD structured as an independent division with career scientists provides a buffer against industry pressure. Relocating research into the administrator's office -- a political appointee position -- removes that institutional insulation. Applied research focused on industry-facing compliance solutions differs fundamentally from basic research into health effects: the former serves industry's immediate compliance needs, while the latter surfaces inconvenient findings about pollution's actual human costs. PEER's executive director, Kaitlyn Ferland, has stated publicly that the ORD dissolution signals EPA's shift toward serving industry convenience over public health evidence.
