Approval and Promulgation of Air Quality Implementation Plans; Commonwealth of Pennsylvania; Interim Final Determination That Pennsylvania Continues To Correct the Deficiencies of its Enhanced I/M SIP Revision; Extension of Comment Period

In this document, EPA is reopening the comment period for a document published on September 16, 1998 (63 FR 49434). In the September 16 document, EPA made an interim final determination that the Commonwealth of Pennsylvania has corrected the deficiency under the Clean Air Act for failure to have an approved enhanced I/M SIP. EPA's September 16 interim final rule deferred the application of Clean Air Act sanctions which would otherwise have been implemented on August 29, 1998. Although that action was effective upon its publication, EPA took comments from the public until October 16, 1998. At the request of a commenter, EPA is re-opening the comment period through November 16, 1998. All comments received on or before November 16, 1998 will be entered into the public record and considered by EPA before taking final action on the interim final rule.
