ACTION: Notice of proposed rulemaking; extension of the comment period. ----------------------------------------------------------------------- SUMMARY: The EPA is extending the comment period for a proposed action published on July 21, 1994 (59 FR 37190) pertaining to the Detroit-Ann Arbor moderate ozone nonattainment area. On July 21, 1994, the EPA proposed approval of requested revisions to the Michigan State Implementation Plan (SIP) for attainment and maintenance of the National Ambient Air Quality Standard for ozone. The revisions were the 1990 base year emission inventory, basic vehicle inspection and maintenance, and redesignation of the Detroit-Ann Arbor area to attainment for ozone and corresponding section 175A maintenance plan. Portions of the document pertaining to the redesignation request and section 175A maintenance plan were inadvertently excluded from the document. Specifically, the last portion of section C.III.5.B. Demonstration of Maintenance--Projected Inventories and the first portion of section C.III.5.C. Verification of Continued Attainment were excluded. Elsewhere in this Federal Register a correction notice is being published for these two sections. Consequently, the EPA is extending the comment period for 15 days on the redesignation and corresponding section 175A maintenance plan. DATES: Comments on the July 21, 1994 (59 FR 37190) proposed action pertaining to the redesignation and corresponding section 175A maintenance plan and today's correction document must be received in writing by September 23, 1994.
