Approval and Promulgation of Implementation Plan; Illinois

摘要

On October 1, 1993, (58 FR 51279) the Environmental Protection Agency (EPA) proposed rulemaking in response to an October 22, 1990, Petition for Reconsideration filed with the Administrator. This Petition requested that EPA reconsider and revise the requirements of the Chicago Federal Implementation Plan (FIP) for Ozone (which was promulgated June 29, 1990 (55 FR 26814)) as they pertain to Stepan Company's Millsdale Plant (Stepan) manufacturing facility in Elwood, Illinois. On December 2, 1993 (58 FR 63547) at the request of Stepan, EPA extended the comment period until December 16, 1993. On December 2, 1993, Stepan requested that the comment period be extended until February 15, 1994 based upon the complexity of the proposed rule and issues raised about the content of the record. At Stepan's request EPA is extending the public comment period until February 15, 1994.
