Approval and Promulgation of Implementation Plans; Illinois

الملخص

On March 24, 1993, the United States Environmental Protection Agency (USEPA) proposed to approve a January 4, 1989 revision to the Illinois sulfur dioxide (SO 2) State Implementation Plan (SIP), and solicited public comment on the proposed action. This document responds to the public comments received and announces approval of the requested revision, which amends the SIP to provide SO 2 emission limits for the Shell Oil Complex in Roxana, Wood River Township, Illinois. This action also clarifies USEPA's approval of related Illinois SO 2 rules which were included in Illinois' January 4, 1989 submittal but were subsequently revised and resubmitted. The USEPA's approval of these rules satisfies the September 28, 1984 notice of SIP deficiency for Wood River Township. The USEPA's action is based upon a revision request which was submitted by the State to satisfy the requirements of the Clean Air Act.
