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 Environmental Protection Agency (EPA) is approving changes to Colorado's State Implementation Plan (SIP) concerning air quality control, specifically targeting ozone levels in certain areas. This involves updates to Regulation Number 7 for better management of emissions like volatile organic compounds (VOCs) and nitrogen oxides (NOx) following the 2008 ozone standards. The action also corrects an oversight from a 2018 rule. This decision is made under the Clean Air Act and does not impose any extra requirements beyond those set by state law.

The Environmental Protection Agency (EPA) is finalizing a rule regarding air quality standards in Arizona's Maricopa County. The rule involves a mix of limited approval and disapproval concerning revisions to rules about emissions of volatile organic compounds (VOCs) from loading organic liquids and gasoline. Though some rules improve the state's plan and meet the Clean Air Act standards, others are deficient, requiring Arizona to make corrections. If not corrected within two years, federal sanctions may be imposed.
