40 CFR Part 52

[MI24-01-6259b; FRL-5054-4]

Approval and Promulgation of State Implementation Plan; Michigan;

Miscellaneous Rule Changes, Technical Changes

AGENCY: United States Environmental Protection Agency (USEPA).

ACTION: Proposed rule.

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

SUMMARY: The USEPA proposes partial approval and partial disapproval of

a revision to the Michigan State Implementation Plan (SIP)

incorporating technical changes to miscellaneous air control rules.

These changes are not federally mandated, but the State has requested

that USEPA incorporate the changes into the SIP. In the final rules

section of this Federal Register, the USEPA is acting on this matter in

a direct final rule without prior proposal because the Agency views

this as a noncontroversial action and anticipates no adverse comments.

A detailed rationale for the partial approval and partial disapproval

is set forth in the direct final rule. If no adverse comments are

received in response to the direct final rule, no further activity is

contemplated in relation to this proposed rule. If the USEPA receives

adverse comments, the direct final rule will be withdrawn and all

public comments received will be addressed in a subsequent final rule

based on this proposed rule. The USEPA will not institute a second

comment period on this document. Any parties interested in commenting

on this document should do so at this time.

DATES: Comments on this proposed rule must be received in writing by

October 17, 1994.

ADDRESSES: Written comments should be sent to: Carlton T. Nash, Chief,

Regulation Development Section, Air Toxics and Radiation Branch (AT-

18J), U.S. Environmental Protection Agency, 77 West Jackson Boulevard,

Chicago, Illinois 60604.
