New EPA Rules on TCE and PCE for Chemical Safety

The United States Environmental Protection Agency (EPA) implemented new regulations concerning trichloroethylene (TCE) and perchloroethylene (PCE) on December 9, 2024. These rules represent advancement in chemical safety, following years of insufficient protections. The regulations fall under the 2016 Toxic Substances Control Act (TSCA) and aim to eliminate the risks associated with these harmful substances.

Background on TCE and PCE

TCE and PCE are industrial solvents commonly used in various applications. They are linked to severe health issues including kidney cancer, Non-Hodgkin lymphoma, and other serious conditions. The EPA’s new rules ban all consumer uses of TCE and many commercial uses of PCE. This decision aligns with President Biden’s Cancer Moonshot initiative, which seeks to end cancer through national efforts.

Key Provisions of the New Rules

The EPA’s regulations prohibit all uses of TCE and restrict many applications of PCE. Remaining uses will require worker protections. These measures aim to safeguard public health and prevent exposure to carcinogenic chemicals. The EPA’s actions are based on extensive scientific research that marks the dangers posed by these substances.

Historical Context and Advocacy

The push for stricter regulations has roots in historical events. Notably, Anne Anderson’s advocacy was very important in raising awareness about the dangers of these chemicals. Her personal tragedy, losing her son to leukemia, catalysed a movement that led to investigations and regulatory changes. In 1979, contamination in Woburn, Massachusetts, prompted the shutdown of municipal wells, denoting the urgent need for chemical safety.

Industry Response and Legal Actions

The American Chemistry Council (ACC) expressed concern over the potential impact of these regulations on industrial uses of TCE. They argue that while safety is paramount, the restrictions should not unduly affect valuable industrial applications. Additionally, legal actions have been initiated against companies like EnPro Industries for illegal discharges of TCE, which have resulted in environmental contamination and health crises in affected communities.

Public Health Implications

The new EPA rules are expected to reduce the risk of cancer and other health issues linked to TCE and PCE exposure. The regulations reflect a growing recognition of the need for stringent chemical safety measures. They also highlight the importance of community advocacy in shaping public policy and protecting health.

Future Directions in Chemical Safety

With these new rules, the EPA aims to establish a framework for ongoing chemical safety evaluations. This includes monitoring the effects of the new regulations and ensuring compliance among industries. The initiative is part of a broader effort to mitigate health risks associated with toxic substances in the environment.
