40 CFR Part 52

[WI32-01-5763b; FRL-4892-2]

Approval and Promulgation of Implementation Plan; Wisconsin

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule.

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

SUMMARY: United States Environmental Protection Agency (USEPA) proposes

full approval of Wisconsin's 1990 base year ozone (O3) emission

inventory as a revision to the Wisconsin State Implementation Plan

(SIP) for O3. The inventory was submitted by the State of

Wisconsin to satisfy a Federal requirement that those States containing

O3 nonattainment areas (NAAs) classified as marginal to extreme

submit inventories of actual O3 season emissions from all sources

in accordance with USEPA guidance. In the final rules section of this

Federal Register, USEPA is approving the State's SIP revision as a

direct final rule without prior proposal, because the Agency views this

as a noncontroversial revision amendment 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 on this 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rule will be withdrawn and all public comments received will be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 this proposed rule. 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 before July 15,

1994.

ADDRESSES: Written comments can be mailed to Carlton T. Nash, Chief,

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

18J), United States Environmental Protection Agency, Region 5, Air and

Radiation Division, 77 West Jackson Boulevard, Chicago, Illinois 60604.

Copies of the SIP revision and USEPA's analyses are available for

inspection at the following address: (It is recommended that you
