ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[IN37-1-6217B, IN38-1-6256B; FRL-5001-1]

Approval and Promulgation of Implementation Plan; Indiana

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule.

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

SUMMARY: The United States Environmental Protection Agency (USEPA)

proposes to approve Indiana's 1990 base year ozone precursor

inventories for certain ozone nonattainment areas as a revision to the

Indiana ozone State Implementation Plan (SIP). The emission inventories

were submitted by the State of Indiana to satisfy a Federal requirement

that States containing ozone nonattainment areas submit inventories of

actual ozone precursor emissions in accordance with USEPA guidance. The

ozone nonattainment areas covered by the emission inventories addressed

in this rulemaking are Evansville (Vanderburgh County); Indianapolis

(Marion County); Louisville (Clark and Floyd Counties); and South Bend/

Elkhart (Elkhart and St. Joseph Counties). In the final rules section

of this Federal Register, the USEPA is approving the State's SIP

revision as a direct final rule without prior proposal because USEPA

views this as a noncontroversial revision and anticipates no adverse

comments. A detailed rationale for the approval 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final rule will be withdrawn and all public comments received will be

addressed in a subsequent final rule based on the proposed rule. USEPA

will not institute a second comment period on this notice. Any parties

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

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

July 20, 1994.

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

Chief, Regulatory Development Section, Regulatory Development Branch

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

Jackson Boulevard, Chicago, Illinois 60604.
