Clean Air Act Proposed Interim Approval of Operating Permits

Program; Pinal County Air Quality Control District, Arizona

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed Rule.

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

SUMMARY: The EPA is proposing interim approval of the revised Operating

Permits Program submitted by the Arizona Department of Environmental

Quality (ADEQ) on behalf of the Pinal County Air Quality Control

District (Pinal) for the purpose of complying with federal requirements

for an approvable state program to issue operating permits to all major

stationary sources, and to certain other sources. The EPA's proposed

interim approval is of specific revisions to the program originally

submitted by ADEQ on Pinal's behalf on November 15, 1993 and

supplemented on August 16, 1994 and August 15, 1995. The EPA proposed

approval of the original program on July 13, 1995 and is taking final

action elsewhere in today's Federal Register to finalize interim

approval of that program.

Today's action proposes interim approval of specified portions of

the Pinal County Code of Regulations amended on February 22, 1995, and

submitted to EPA on August 15, 1995, that are relevant to

implementation and enforcement of the Pinal County title V operating

permits program. The specific provisions of Pinal's title V regulations

adopted or revised on February 22, 1995 that are addressed by this

proposed action are Sections 1-3-140(1a), 140(16a), 140(44), 140(56),

140(58e), 140(59), 140(66), 140(86), 140(89), and 140(146) of Article 3

of Chapter 1; Sections 3-1-042, 045(C), 050(C)(4), 050(G), 080(A),

081(A)(5)(b), 081(A)(6), 100(A), and 109 of Article 1 of Chapter 3; and

Articles 5 and 7 of Chapter 3 of the Pinal County Code of Regulations

(PCR).

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

promulgating interim approval of Pinal's revised title V program 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will be withdrawn and all public comments received will be addressed in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

November 29, 1996.

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