[AZ 063-0001b; FRL-5452-3]

Clean Air Act Approval and Promulgation of Prevention of

Significant Deterioration (PSD) and General Permitting Provisions

Implementation Plan for Arizona State Pinal County Air Quality Control

District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing approval of portions of a requested State

Implementation Plan (SIP) revision submitted by the State of Arizona

for the purpose of meeting requirements of the Clean Air Act, as

amended in 1990 (CAA or Act) with regard to general permitting programs

and prevention of significant deterioration (PSD) in areas of Pinal

County that are in attainment of the national ambient air quality

standards (NAAQS). The requested revision was submitted by the State to

satisfy certain Federal requirements for an approvable SIP.

EPA is taking this action to approve the portions of Pinal's rules

identified below into the SIP for the purpose of meeting the PSD and

preconstruction permitting requirements of 40 CFR 51.160 through 51.164

and 51.166, under the authority granted by 40 CFR 51.105. Approval of

Pinal's rules for the purposes of meeting the nonattainment

preconstruction permitting requirements of 40 CFR 51.165 will take

place under a separate action. This action does not in any way imply

that Pinal's nonattainment permitting provisions meet the requirements

of sections 171, 172, 173, 181, 182, 187, or 189 of the CAA. Failure on

Pinal's part to submit rules which meet the requirements of 40 CFR

51.165 may trigger sanctions as provided for under section 179 of the

Clean Air Act.

In the final rules section of this Federal Register, EPA is

promulgating approval of Pinal's PSD and general permitting rules as a

direct final rule without prior proposal because EPA views this

submittal as noncontroversial and anticipates no adverse comments. A

detailed rationale for this approval 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

rulemaking. If EPA 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will be withdrawn and all public comments received will be addressed in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 EPA will not

institute a second comment period on this document. Any parties

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

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

May 9, 1996.

ADDRESSES: Written comments on this action should be addressed to:

Jessica Gaylord, New Source Section (A-5-1), Air and Toxics Division,

U.S. Environmental Protection Agency, Region IX, 75 Hawthorne Street,

San Francisco, CA 94105.

Copies of the County's submittal, EPA's Technical Support Document,

and other supporting information used in developing the proposed

approval are available for public inspection at EPA's Region IX office

during normal business hours.

final rule of the same title which is located in the Rules section of

this Federal Register.

Authority: 42 U.S.C. 7401-7671q.

Dated: March 4, 1996.

Felicia Marcus,

Regional Administrator.
