Approval and Promulgation of Implementation Plans; Illinois

On August 21, 1995, U.S. EPA promulgated a site-specific volatile organic material (VOM) rule for Riverside Laboratories, Inc.'s (Riverside) Kane County facility. The rule consisted primarily of a compliance date extension for Riverside through December 31, 1996, after which time Riverside is required to meet the applicable requirements of the Chicago-area Federal Implementation Plan (FIP). On October 10, 1997, the State of Illinois requested that U.S. EPA approve a change in regulatory status for Riverside, based on Riverside's current compliance with the applicable State Implementation Plan (SIP) rule. For the reasons discussed below, U.S. EPA is today approving the State plan as applying to Riverside. U.S. EPA is taking this action as a ``direct final'' rulemaking; the rationale for this approach is set forth below. Elsewhere in this Federal Register, U.S. EPA is proposing this action and soliciting comment. If adverse written comments or a request for a public hearing are received, U.S. EPA will withdraw the direct final rule and it will not take effect. U.S. EPA will address the comments received in a new final rule. If no adverse written comments are received, no further rulemaking will occur on this requested SIP revision.
