| E7-25405 | Approval and Promulgation of Air Quality Implementation Plans; Illinois | Proposed Rule | EPA is proposing disapproval of a revision to the Illinois Ozone State Implementation Plan (SIP). On August 17, 2005, Illinois requested that five compounds be added to its list of compounds exempt from being considered a volatile organic compound (VOC). EPA no longer considers four of the compounds to be VOCs because the compounds were shown to be negligibly photochemically reactive. Thus, the compounds do not lead to ozone formation. For the fifth compound, t-butyl acetate, EPA determined that it is not considered a VOC for emission limits and VOC content requirements, but it is considered a VOC for recordkeeping, emission reporting, and inventory requirements. Illinois has indicated it is correcting the restrictions on t-butyl acetate. Consequently, EPA is alternatively proposing approval of the SIP revisions if t-butyl acetate is removed from the list of compounds exempt from being considered VOC or if the special requirements for t-butyl acetate are clearly indicated. Illinois must submit the supporting documentation during the comment period for this rule. | 2007-12-31 | 2007 | 12 | https://www.federalregister.gov/documents/2007/12/31/E7-25405/approval-and-promulgation-of-air-quality-implementation-plans-illinois | https://www.govinfo.gov/content/pkg/FR-2007-12-31/pdf/E7-25405.pdf | Environmental Protection Agency | 145 | EPA is proposing disapproval of a revision to the Illinois Ozone State Implementation Plan (SIP).
