ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[MI24-02-6743; FRL-5111-1]

 

Approval and Promulgation of State Implementation Plan; Michigan; 
Miscellaneous Rule Changes, Technical Changes

AGENCY: United States Environmental Protection Agency (USEPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: On September 15, 1994, the USEPA published simultaneous 
proposed and final rules partially approving and partially disapproving 
a revision to the Michigan State Implementation Plan (SIP) 
incorporating technical changes to miscellaneous air control rules. On 
October 17, 1994, the State withdrew the parts of its submittal which 
USEPA disapproved. In response, this notice reclassifies the September 
15, 1994 action as a full approval.

EFFECTIVE DATES: This rule becomes effective on November 23, 1994.

ADDRESSES: Copies of the State's submittals and USEPA's analysis are 
available for inspection at the U.S. Environmental Protection Agency, 
Region 5, Air and Radiation Division, 77 West Jackson Boulevard, 
Chicago, Illinois 60604. (Please telephone Megan Beardsley at (312) 
886-0669 to arrange an appointment before visiting the Region 5 
office.)
    Copies of the State's submittals also are available at the Office 
of Air and Radiation, Docket and Information Center (Air Docket 6102), 
Room M1500, U.S. Environmental Protection Agency, 401 M Street, SW., 
Washington, DC 20460, (202) 260-7548.

FOR FURTHER INFORMATION CONTACT: Megan Beardsley, Environmental 
Scientist, Regulation Development Section, Air Toxics and Radiation 
Branch (AT-18J), U.S. Environmental Protection Agency, Region 5, 
Chicago, Illinois 60604, (312) 886-0669.

SUPPLEMENTARY INFORMATION:
    On November 12, 1993, the State of Michigan requested that the 
USEPA revise its SIP to incorporate a number of technical rule changes 
that the State adopted in 1989. Most of these changes were minor, 
clarifying rules or removing definitions of terms no longer used in 
Michigan law, but some changes were more substantial. None of the 
changes were required by the Clean Air Act (the Act) or other Federal 
law or policy. However, because the State requested that USEPA 
incorporate the changes into the SIP, USEPA reviewed the changes to 
assure that they were in accordance with the Act. Most of the changes 
submitted by the State clarified and strengthened the SIP, but several 
were not approvable.
    On September 15, 1994, in accordance with Agency procedures for 
``direct final'' rulemaking (see April 2, 1994 memorandum from Jerry M. 
Stubberfield, Acting Chief, Regional Operations Branch, to Air Branch 
Chiefs, ``State Implementation Plan (SIP) Direct Final Processing 
Procedures''), the USEPA published simultaneous proposed and final 
rules (59 FR 47287 and 59 FR 47254). These rules partially approved the 
State's submittal and provided a public comment period ending October 
17, 1994. Because notice of intent to submit adverse comments was not 
received by October 17, 1994, the rulemaking took effect on November 
14, 1994. However, on October 17, 1994, the State of Michigan withdrew 
those parts of the submittal which USEPA had disapproved. Thus, USEPA 
must change the classification of the September 15, 1994 rulemaking 
from ``partial approval/partial disapproval'' to ``full approval.'' 
That is the purpose of this action.
    Since the distinction between full and partial approval was made 
only in the preambles to the September 15, 1994 notices, the Michigan 
withdrawal and this action in no way affect the amendment of the 
Michigan SIP which USEPA codified in the September 15, 1994 final rule. 
That amendment became effective, as scheduled, on November 14, 1994.
