Abstract
The Environmental Protection Agency (EPA) is approving revised rules submitted by the State of Illinois as State Implementation Plan (SIP) revisions. The submitted rules update Illinois definitions and requirements for handling monitoring data influenced by exceptional events, update implementation rules for the 2012 primary annual National Ambient Air Quality Standard (NAAQS) for fine particulate matter (PM<INF>2.5</INF>), and update designated reference and equivalent methods for multiple NAAQS. In addition, the submitted rules amend the Illinois Administrative Code (IAC) by updating the definition of volatile organic compounds (VOC).
