Summary

The Environmental Protection Agency (EPA) is proposing to approve a state submission as a revision to the Illinois state implementation plan (SIP) for ozone. The revision, submitted on May 30, 2017, incorporates changes to the Illinois Administrative Code definition of volatile organic material, otherwise known as volatile organic compounds (VOC). The revision removes recordkeeping and reporting requirements related to the use of t-butyl acetate (also known as tertiary butyl acetate) as a VOC, and is in response to an EPA rulemaking that occurred in 2016. Illinois also added information to provide clarity to the list of compounds excluded from the definition of VOC.

The agency’s own summary, as published.
