[FRL-5279-7]

Designation of Areas for Air Quality Planning Purposes; Wyoming;

Redesignation of Particulate Matter Attainment Areas

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of proposed rulemaking.

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

SUMMARY: In this document, the EPA is proposing to approve the State of

Wyoming's December 19, 1994 request to redesignate the Powder River

Basin particulate matter attainment area to exclude the Kennecott/Puron

Prevention of Significant Deterioration (PSD) Baseline area, pursuant

to section 107 of the Clean Air Act. EPA is also proposing to designate

the Kennecott/Puron PSD Baseline area as a separate particulate matter

attainment area. In the final rules section elsewhere in this Federal

Register, the EPA is acting on the State's request in a direct final

rule without prior proposal because the Agency views this action as

noncontroversial and anticipates no adverse comments. A detailed

rationale for the action is set forth in the direct final rule. If no

adverse comments are received in response to this proposed rule, no

further activity is contemplated in relation to this rule. If the EPA

receives adverse comments, then the direct final rule will be withdrawn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 EPA 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 action must be received in writing by

October 12, 1995.

ADDRESSES: Written comments should be addressed to Vicki Stamper, 8ART-

AP, at the EPA Regional Office listed below. Copies of the documents

relevant to this proposed rule are available for public inspection

during normal business hours at the following locations: Air Programs

Branch, Environmental Protection Agency, Region VIII, 999 18th Street,

Suite 500, Denver, Colorado 80202-2466; and Air Quality Division,

Wyoming Department of Environmental Quality, 122 West 25th Street,

Hershler Building, Cheyenne, Wyoming 82002.
