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.
Simple Explanation
The EPA wants to change a rule in Illinois by saying a certain chemical isn't bad for the air because it doesnβt make smog.
