EPA Extends Public Comment Periods for C.I. Pigment Violet 29 and Vinyl Chloride Chemical Risk Evaluations

The U.S. Environmental Protection Agency has extended the public comment periods for two key chemical evaluations under the Toxic Substances Control Act (TSCA), allowing stakeholders additional time to provide feedback on regulatory decisions for C.I. Pigment Violet 29 (PV29) and vinyl chloride. 

Extended Comment Period for C.I. Pigment Violet 29    

On January 14, 2025, EPA released a proposed risk management rule for C.I. Pigment Violet 29 (PV29), a chemical commonly used in paints, coatings, and plastics. The public comment period was originally scheduled to close on February 28, 2025. However, the agency has now extended the deadline by 60 days, to April 29, 2025. 

The extension is intended to give stakeholders, including industry representatives, environmental groups, and the public, more time to review the proposed regulations and submit their comments. Those interested can provide input through the official docket (EPA-HQ-OPPT-2021-0277) at www.regulations.gov. 

Vinyl Chloride Risk Evaluation Comment Period Extension   

Similarly, EPA has extended the comment period for the draft scope document for the risk evaluation of vinyl chloride, a chemical used primarily in the production of PVC plastics. The draft scope document was initially released with the original comment period set to close on March 3, 2025. The extension grants stakeholders an additional 30 days, extending the deadline to April 2, 2025. 

EPA encourages interested parties to submit feedback on the draft risk evaluation through the docket (EPA-HQ-OPPT-2018-0448) at www.regulations.gov.
