EPA is advancing its review of five chemicals under the Toxic Substances Control Act (TSCA) and has released draft technical support documents for public comment and independent scientific peer review.
The chemicals under review include:
• Tetrabromobisphenol A (TBBPA)
• Ethylene Dibromide (EDB)
These chemicals are used in products and processes including flame retardants, cleaning and degreasing products, leaded aviation gasoline, laboratories, and industrial manufacturing.
EPA’s draft assessments examine potential risks to:
• Workers and occupational settings
• Communities located near sources of exposure
• Children and other sensitive populations
• Fish, wildlife, and environmental resources
EPA is emphasizing the use of current scientific data and is seeking feedback on how real-world exposures should be considered in future risk evaluations.
Public Comment Deadline: July 23, 2026
Comments on the draft technical support documents and peer review questions may be submitted through Docket EPA-HQ-OPPT-2026-2246 at Regulations.gov.
