Detailed Overview of the Asbestos Ban under the Biden-Harris Administration
The new regulations target the cessation of chrysotile asbestos use, which is prevalent in various products.
Key takeaway
What this development means
The EPA’s Part 2 Risk Evaluation for Asbestos highlights the serious health risks posed by legacy uses and associated disposals of asbestos. The report, mandated by a 2019 court ruling, extends its scope to include additional fibre types and past uses still present in older infrastructure. Regulatory action is expected to mitigate these risks, focusing on workers, first responders, and others exposed to disturbed asbestos materials.
What are legacy uses of asbestos?
Legacy uses refer to asbestos applications no longer in production but still present in existing materials, such as insulation, ceiling tiles, and pipe wraps. These materials can release hazardous fibres if disturbed.
What steps will the EPA take following this evaluation?
The EPA will propose risk management regulations under TSCA Section 6, which could include labelling, restrictions, or bans to mitigate asbestos-related risks. Public input will shape these measures.

The U.S. Environmental Protection Agency (EPA) has concluded its Part 2 Risk Evaluation for Asbestos under the Toxic Substances Control Act (TSCA). Released on 3 December 2024, the evaluation highlights the unreasonable health risks posed by asbestos, particularly from legacy uses and associated disposals. Key findings reveal significant exposure risks to workers, first responders, and individuals near demolition sites, necessitating regulatory action to mitigate these hazards.
Understanding Asbestos and Its Risks
Asbestos, a fibrous mineral historically used in construction and various industrial applications, poses severe health risks when disturbed. Inhalation of airborne fibers can cause diseases such as asbestosis, mesothelioma, and lung, ovarian, and laryngeal cancers.
Legacy uses, where asbestos remains in older materials like insulation, tiles, and pipe wraps, contribute heavily to these risks. Although its use has diminished, materials containing asbestos remain present in older structures, creating exposure risks during demolition or renovation.
EPA's Evaluation and Key Findings
This evaluation, a supplement to the 2020 Part 1 Risk Evaluation, addressed previously excluded legacy uses and associated disposals of six asbestos fiber types. It found substantial risks for workers handling or disturbing asbestos and their families exposed via contaminated clothing. It also highlighted dangers to first responders and DIY enthusiasts engaging in renovations.
Notably, the EPA ruled out significant risks to individuals where asbestos-containing materials remain undisturbed. The agency did not evaluate trace amounts of asbestos in non-TSCA-regulated products like certain talc-containing cosmetics.
Regulatory and Risk Management Implications
Under TSCA Section 6, the EPA must propose measures to eliminate identified risks. Options may include labelling, usage restrictions, or outright bans on specific asbestos uses. Public comments will shape the final regulatory actions.
Broader Impact and Next Steps
The findings underscore the need for comprehensive safety measures in industries and communities. The EPA’s upcoming regulations aim to mitigate exposure, safeguarding vulnerable populations such as construction workers and first responders.
