## Abstract

The EPA is approving Illinois' October 31, 2003 request to revise the definition of volatile organic material (VOM) and volatile organic compound (VOC) to incorporate exemptions for several nonreactive compounds from the definition of VOM and VOC and thereby, from regulation as ozone precursors. These requested state implementation plan (SIP) revisions were made in response to, and consistent with, EPA's action to add these chemical compounds to the list of chemicals that are exempted from the definition of VOC. In the proposed rules section of this Federal Register, EPA is proposing approval of and soliciting public comment on these requested SIP revisions. If adverse comments are received on this action, EPA will withdraw this final rule and address the comments received in response to this action in a final rule on the related proposed rule which is being published in the proposed rules section of this Federal Register. A second public comment period will not be held. Parties interested in commenting on this action should do so at this time.
