[MI21-03-6635; AMS-FRL-5067-1]

 

Approval and Promulgation of Implementation Plans and Designation 
of Areas for Air Quality Planning Purposes; Michigan; Extension of 
Comment Period

AGENCY: Environmental Protection Agency (EPA).

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.
