Approval and Promulgation of Air Quality Implementation Plans; Illinois

Mon, Dec 31 2007 11:00:00 GMT

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, tbutyl 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 tbutyl acetate. Consequently, EPA is alternatively proposing approval of the SIP revisions if tbutyl acetate is removed from the list of compounds exempt from being considered VOC or if the special requirements for tbutyl acetate are clearly indicated. Illinois must submit the

Clean Air Act Reclassification of the Houston/Galveston/Brazoria Ozone Nonattainment Area; Texas; Proposed Rule

Mon, Dec 31 2007 11:00:00 GMT

EPA proposes to grant a request by the Governor of the State of Texas to voluntarily reclassify the Houston/Galveston/Brazoria (HGB) ozone nonattainment area from a moderate 8hour ozone nonattainment area to a severe 8hour ozone nonattainment area. This request was made in a letter from Governor Rick Perry to the EPA Administrator on June 15, 2007. In addition to the reclassification proposal, EPA is also proposing and taking comment on a range of dates from December 15, 2008 to April 15, 2010 for the State to submit a revised State
Implementation Plan (SIP) addressing the severe ozone nonattainment area requirements of the Clean Air Act (CAA).

EPA will accept comments on all aspects of this proposed action. However, as discussed in Section II below, the CAA mandates the Agency to grant a voluntary reclassification when requested by a State.
