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 April 2, 1996 (61 FR 14522) pertaining to the Grand Rapids

moderate ozone nonattainment area. On April 2, 1996, the EPA proposed

approval of Michigan's request to redesignate the Grand Rapids moderate

ozone nonattainment area to attainment for ozone and associated section

175A maintenance plan revision to the Michigan State Implementation

Plan (SIP) contingent on the State's submittal of a revision to the

maintenance plan to incorporate 3 additional control programs to the

list of contingency measures. On April 19, 1996, the EPA received a

request for an extension of the public comment period based on the fact

that the revision to the section 175A maintenance plan SIP was not

available in the EPA's docket until April 15, 1996. Since the revision

to the section 175A maintenance plan SIP revision was not available for

approximately the first two weeks of the public comment period, the EPA

is extending the comment period only on the aspects of the

redesignation and corresponding section 175A maintenance plan SIP

revision components pertaining to the State's revision to the

maintenance plan submitted on April 15, 1996 for 14 days. The public

comment period pertaining to the other components of the redesignation

request and maintenance plan SIP revision are not extended and comments

on these components are due to EPA by May 2, 1996.

DATES: Comments on the aspects of the April 2, 1996, (61 FR 14522)

proposed action on the redesignation and corresponding section 175A

maintenance plan pertaining to the State's April 15, 1996 SIP revision

must be received in writing by May 16, 1996.
