Post: Proposed Expansion of EPA’s “Hazardous Constituent” List Targets More PFAS Compounds


A Step Forward in Addressing the Threats of Forever Chemicals

The United States Environmental Protection Agency (EPA) is taking significant steps to address the dangers posed by Per- and Polyfluoroalkyl Substances, commonly known as PFAS or “forever chemicals.” In a recent statement, EPA Administrator Michael Regan announced the proposal to label nine PFAS compounds as hazardous under the Resource Conservation and Recovery Act (RCRA) regulations. This move signifies the agency’s commitment to cleaning up PFAS contamination, protecting public health, and holding polluters accountable.

EPA’s Focus on Prominent PFAS Compounds, Salts, and Structural Isomers

Inclusion in the list of “hazardous constituents” requires a chemical to demonstrate its threat to human or environmental health through studies showing toxicity, carcinogenicity, mutagenicity, or teratogenicity. The proposed expansion targets:

  • Some of the most prevalent PFAS compounds
  • Their salts
  • Structural isomers

Experts have found these compounds to be more dangerous than initially thought, as they can cause harm at much lower levels than previously believed.

Why Are PFAS Chemicals Problematic?

PFAS are synthetic chemicals known for their ability to make materials water-, grease-, and stain-resistant. They have been used in various applications such as firefighting foams, non-stick cookware, food packaging, and stain-resistant carpets. These chemicals are extremely persistent, remaining in the environment and building up in humans and animals over time.

Long-term exposure to PFAS has been linked to various health problems, including:

  • Cancer
  • Immune system disruption
  • Changes in liver and thyroid function
  • Developmental issues in fetuses and infants

With thousands of these compounds used worldwide, it has become increasingly important for regulatory agencies like the EPA to establish stronger measures that safeguard our environment and public health from their impacts.

Environmentalists Call for a Complete Ban on All PFAS Chemicals

Although the EPA’s recent proposal marks a significant milestone in addressing PFAS contamination, many environmental advocates argue that this move is insufficient. They urge the agency to ban all PFAS chemicals altogether instead of just focusing on nine specific compounds. With thousands of variants in use, they maintain that partial regulation may leave other harmful substances unchecked.

Nonetheless, the proposed labeling of these nine PFAS compounds as hazardous constituents would mark an unprecedented step towards mitigating the impact these chemicals have on the human population and our environment.

Looking Ahead: The Future of PFAS Regulation

As the EPA moves forward with its proposal, we can expect continued dialogue and debate surrounding the most effective approach to regulating PFAS chemicals. Appropriate action will likely involve striking a balance between necessary precautionary measures and minimizing economic disruption for industries reliant upon PFAS-compound technologies.

The recent announcement indicates a growing awareness of the threats posed by “forever chemicals” by government agencies and reinforces the need for a proactive response to safeguarding environmental and human health.

Key Takeaways

In conclusion:

  • The EPA proposes the addition of nine prevalent PFAS compounds, their salts, and structural isomers to the list of “hazardous constituents.”
  • These chemicals are more dangerous than previously thought, posing a threat at lower concentrations and through long-term exposure.
  • Environmentalists applaud the announcement but argue for a total ban on all PFAS chemicals instead of just targeting specific compounds.

With public health and wellbeing under threat from these persistent contaminants, government agencies face increasing pressure to adopt comprehensive measures that protect both our environment and communities. The proposed expansion of the hazardous constituent list marks an important move towards addressing this growing concern.
