ENVIRONMENTAL PROTECTION AGENCY

40 CFR Parts 52 and 81

[IN15-2-6326B; FRL-5008-6]

Approval and Promulgation of Implementation Plans and Designation

of Areas for Air Quality Planning Purposes; Indiana

AGENCY: Environmental Protection Agency (USEPA).

ACTION: Proposed rule.

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

SUMMARY: The USEPA is proposing to approve requests to redesignate

Indiana marginal ozone nonattainment areas to attainment. The USEPA is

also proposing to approve accompanying maintenance plans as State

Implementation Plan (SIP) revisions. The redesignation requests and

maintenance plans were submitted by the Indiana Department of

Environmental Management (IDEM) for the following ozone nonattainment

areas: St. Joseph and Elkhart, Vanderburgh and Marion Counties. The

State has met the requirements for redesignation contained in the Clean

Air Act, as amended in 1990. In the final rules section of this Federal

Register, the USEPA is approving the State's redesignation requests and

the supporting maintenance plans without prior proposal because USEPA

views these as noncontroversial revisions and anticipates no adverse

comments. A detailed rationale for the approvals is set forth in the

direct final rule. If no adverse comments are received in response to

that direct final rule, no further activity is contemplated in relation

to this proposed rule. If USEPA receives adverse comments, the direct

final rule will be withdrawn and the public comments received will be

addressed in a subsequent final rule based on this proposed rule. A

second comment period on this action will not be held. Parties

interested in commenting on this notice should do so at this time.

Adverse comments received concerning a specific geographic area, St.

Joseph and Elkhart, Vanderburgh or Marion Counties, will only affect

the final rule as it pertains to that area and only the portion of the

final rule concerning the area receiving adverse comments will be

withdrawn.

DATES: Comments on this proposed rule must be received on or before

August 8, 1994.

ADDRESSES: Written comments should be mailed to: J. Elmer Bortzer,

Chief, Regulation Development Section, Regulation Development Branch

(AR18-J), U.S. Environmental Protection Agency, Region 5, 77 West

Jackson Boulevard, Chicago, Illinois 60604.
