Proposed EPA Rule Could Evaluate Toxic Chemical Risks with Less Rigor, Limit State Powers

Proposed Changes to Chemical Safety Reviews

The Environmental Protection Agency under the Trump administration has proposed a new rule that would significantly alter how some of the nation’s most toxic chemicals are evaluated for safety, according to reports from public health advocates and an EPA employee. The rule would affect substances including PFAS, formaldehyde, asbestos, and dioxins, which are known to pose serious health risks in consumer goods and workplaces.

Key Provisions and Potential Impacts

The proposed regulation would shorten the timeframe for chemical reviews and modify the methodology used to assess dangers, sources indicate. It would also prohibit states from banning or restricting hazardous chemicals, potentially invalidating hundreds of existing state-level protections. Analysts suggest this could centralize chemical regulation at the federal level while reducing local autonomy.

Kyla Bennett, a former EPA scientist now with Public Employees For Environmental Responsibility, characterized the proposal as “a gift to industry wrapped on golden wrapping paper with a big bow on it,” according to the report. The changes come as the agency reopens evaluations completed under the Biden administration, which had resulted in restrictions on several highly toxic substances.

Controversial Adjustments to Exposure Assessments

The rule would eliminate review of certain exposure routes to chemicals from scrutiny, the report states. Currently, the EPA implements restrictions if exposure to toxic substances through air, water, oral, or dermal contact can be “reasonably foreseen.” An unnamed EPA employee suggested the administration might exploit ambiguity in this language to foresee fewer exposure scenarios.

Additionally, the proposal includes what Bennett termed a “giant loophole,” whereby some dangerous chemicals would not be restricted as long as workers use proper personal protective equipment. However, research indicates workers often forego or misuse such gear, and the rule could prevent enforceable protection requirements, creating a “circular argument” that increases risks, the employee explained.

New Scientific Standards and Industry Response

The rule mandates that risk assessments adhere to the “Gold Standard Science” framework developed by the Trump administration. The EPA employee noted that some stipulations, such as requiring all data to be public despite confidentiality laws, appear impossible to meet, potentially invalidating risk evaluations and hindering regulation.

In contrast, the American Chemistry Council, representing chemical manufacturers, endorsed the changes. Kimberly Wise White, an ACC lobbyist, stated the EPA is “refining its processes in a way that is both protective and practical,” according to a press release.

Implementation Timeline and Political Context

The rule-making process is expected to take approximately three years and will likely face legal challenges. The EPA is reassigning staff to the toxics office, including inexperienced personnel who may be less resistant to political pressure, the employee revealed. Even if a future administration prioritizes stricter reviews, restarting the process could delay changes until after 2031, prolonging regulatory uncertainty., according to related coverage

From a business perspective, slowing the regulatory process allows continued profitability from chemicals under review, the employee added, emphasizing that industry benefits from administrative delays in chemical safety evaluations.
