Approval and Promulgation of Implementation Plans; Illinois

On July 23, 1996, the State of Illinois submitted a site specific State Implementation Plan (SIP) revision request to revise Volatile Organic Material (VOM) Reasonably Available Control Technology (RACT) requirements for Chase Products Company in Broadview (Cook County), Illinois. VOM, as defined by the State of Illinois, is identical to ``volatile organic compounds'' (VOC), as defined by USEPA. Emissions of VOC react with other pollutants, such as oxides of nitrogen, on hot summer days 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. Chicago area RACT rules are intended to establish, for each particular major stationary source in the Chicago ozone nonattainment area, the lowest VOC emission limitation it is capable of meeting by the application of control technology that is reasonably available, considering technological and economic feasibility. RACT controls are a major component of the Chicago ozone nonattainment area's overall strategy to achieve and maintain attainment with the ozone standard. A direct final approval action is being taken because the submittal meets all pertinent Federal requirements.
