Approval and Promulgation of Implementation Plan; Illinois

On March 6, 1998, the State of Illinois submitted to EPA amended rules for controlling Volatile Organic Material (VOM) emissions from wood furniture coating operations in the Chicago and Metro-East (East St. Louis) ozone nonattainment areas, as a requested revision to the ozone State Implementation Plan (SIP). VOM, as defined by the State of Illinois, is identical to ``Volatile Organic Compounds'' (VOC), as defined by EPA. VOC is an air pollutant which combines with nitrogen oxides in the atmosphere to form ground-level ozone, commonly known as smog. Ozone pollution is of particular concern because of its harmful effects upon lung tissue and breathing passages. This plan was submitted to meet the Clean Air Act (Act) requirement for States to adopt Reasonably Available Control Technology (RACT) rules for sources that are covered by Control Techniques Guideline (CTG) documents. This rulemaking action approves, through direct final, the Illinois SIP revision request.
