Approval and Promulgation of Implementation Plan; Illinois

On June 29, 1990, the United States Environmental Protection Agency (USEPA) promulgated Federal stationary source Volatile Organic Compound (VOC) control measures representing Reasonably Available Control Technology (RACT) for emission sources located in six northeastern Illinois (Chicago area) counties: Cook, DuPage, Kane, Lake, McHenry and Will. USEPA also took final rulemaking action on certain VOC RACT rules previously adopted and submitted by the State of Illinois for inclusion in its State Implementation Plan (SIP). Included in USEPA's rule was a requirement that paper coating facilities, such as Riverside Laboratories' (Riverside) Kane County facility, be subject to specified emission limits. On August 20, 1991, Riverside filed a petition for reconsideration with USEPA in which it contended, based on its economic situation, that the Federal rules were not RACT for its facility. As a result of USEPA's reconsideration, it proposed revised RACT requirements for Riverside's facility on December 16, 1993. In this rule the USEPA is promulgating site-specific RACT limits that are generally the same as those in the proposed rule. USEPA is also withdrawing the June 23, 1992, stay.
