The Environmental Protection Agency (EPA) is proposing a change to the Illinois State Implementation Plan (SIP) regarding air quality regulations. This proposal involves updating the definitions of volatile organic material (VOM) and volatile organic compounds (VOC) to exclude the chemical (Z)-1,1,1,4,4,4-hexafluorobut-2-ene, as it was found to have a negligible impact on the formation of harmful ozone in the atmosphere. The revision aligns with a 2018 EPA rule and would not introduce additional requirements beyond those of the existing state law. Public comments on this proposal are open until March 15, 2021.

The U.S. Environmental Protection Agency (EPA) has made changes to rules about aerosol sprays to reduce pollution that contributes to smog. These new amendments focus on using less reactive compounds in aerosol products, and they update testing methods, reporting requirements, and compliance dates for the industry. Companies that make or sell these aerosol products, especially those not operating in California, need to comply by mid-2025, but they can start using the new standards earlier if they choose. The EPA believes these changes won't harm the environment and will help align national and state regulations.
