EPA Officials Interfered with Chemical Safety Studies

By staff - Union of Concerned Scientists, February 17, 2022

What happened: Officials at the Environmental Protection Agency (EPA) directed agency staff to alter certain chemical safety studies in a way that downplayed the chemical’s health risks. EPA officials have pressured staff to alter hazard information, undermine research, and remove scientific information on potentially toxic chemicals.

Why it matters: By interfering with chemical safety studies, EPA officials undermined one of the major ways by which the federal government protects people from exposure to toxic chemicals. Not only does this action violate the Toxic Substances Control Act (TSCA), but it also endangers the health and safety of communities across the US, especially underserved communities.

Officials at the Environmental Protection Agency (EPA) are pressuring agency employees to tamper with the risk assessments of dozens of hazardous chemicals by excluding evidence of adverse health impacts. Reports of deleted language and major revisions in chemical risk assessments against the consent of agency scientists in response to higher management violates the rules and regulations as outlined by the Toxic Substances Control Act (TSCA) of 1976 which states the EPA is required to uphold the “reporting, record-keeping, and testing requirements and restrictions relating to chemical substances and/or mixtures.”

Four EPA scientists who worked at the agency's Office of Chemical Safety and Pollution Prevention stated that they had experienced numerous incidents in which management and staff pressured them or their colleagues to alter risk assessments in a way that fell out of line with the best available scientific evidence. In a complaint submitted to the EPA inspector on behalf of the four scientists, these unauthorized interferences include deleted language identifying potential adverse effects of toxic chemicals, major revisions that alter the conclusions of a toxic chemical’s toxicity, and risk assessments being assigned to inexperienced employees to avoid pushback.
