Clean Air Act Proposed Approval of Title V Operating Permits

Program Revisions; Proposed Approval of Amended Synthetic Minor

Operating Permit Program as a State Implementation Plan Revision; Bay

Area Air Quality Management District, California

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: On November 29, 1994, EPA proposed to grant interim approval

to the title V operating permits program and full approval to the

synthetic minor operating permit program submitted by the Bay Area Air

Quality Management District (Bay Area, BAAQMD, or District) for the

purpose of complying with title V of the Clean Air Act (Act) in the

case of the former, and for creating federally enforceable limits on

potential to emit in the case of the latter. Bay Area has since revised

the two [[Page 32640]] programs, and this document addresses those

revisions. In this document, EPA is proposing approval of Bay Area's

title V operating permits program revisions which add optional permit

shield provisions, clarify permit application requirements, and make

other minor program changes in response to local concerns. EPA is also

proposing to approve revisions to Bay Area's synthetic minor

regulations which clarify permit modification requirements under the

federally enforceable state operating permit program (FESOP). EPA is

proposing approval of the revised synthetic minor regulations as a

revision to Bay Area's portion of the California State Implementation

Plan (SIP) and pursuant to section 112(l) of the Act.

In the Final Rules Section of this Federal Register, EPA is

promulgating direct final approval of Bay Area's title V and FESOP

revisions without prior proposal because EPA views these changes as

noncontroversial amendments and anticipates no adverse comments. A

detailed rationale for these approvals 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will be withdrawn and all public comments received will be addressed in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

July 24, 1995.

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

Celia Bloomfield, Operating Permits Section (A-5-2), Air and Toxics

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

Street, San Francisco, CA 94105.

Copies of the District's submittal, EPA's Technical Support

Document, and other supporting information used in developing the

proposed approvals are available for public inspection at EPA's Region

IX office during normal business hours.

FOR FURTHER INFORMATION CONTACT: Celia Bloomfield (telephone 415/744-

1249), Operating Permits Section (A-5-2), Air and Toxics Division, U.S.

Environmental Protection Agency, Region IX, 75 Hawthorne Street, San

Francisco, CA 94105.

SUPPLEMENTARY INFORMATION: On November 29, 1994, EPA proposed in the

Federal Register to grant interim approval to Bay Area's title V

operating permits program (59 FR 60939) in accordance with title V of

the Act (as amended in 1990) and 40 CFR part 70 (the title V

implementing regulations). In the same notice, EPA proposed approval of

Bay Area's synthetic minor program based on the June 28, 1989 (54 FR

27274) approval criteria for federally enforceable state operating

permit programs. On February 1, 1995, Bay Area adopted revisions to

Regulation 2, Rule 6 (Regulation 2-6) and the District's Manual of

Procedures, Volume II, Part 3 (MOP) that implement the District's title

V and synthetic minor programs. These revisions were not made in

response to the deficiencies identified in the proposed rulemaking, but

rather to address local issues and concerns. EPA is proposing direct

final approval of the amendments to coordinate the effective date of

the title V and FESOP programs with the effective date of the

revisions.

Amendments to Bay Area's title V program were submitted to EPA by

the California Air Resources Board (CARB) on March 23, 1995. The

regulations covered by this direct final approval include: Regulation

2, Rule 6, Sections 232, 233, 234, 305, 307, 311, 403.1, 403.1.1,

403.1.2, 403.1.3, 404.6, 404.7, 405.2, 405.4.1, 405.4.2, 405.6,

405.6.1, 405.6.2, 409.12, 410.6, 411, 418.3, 420, 421.3, 421.4, 422,

422.3, 422.4, 422.6, 423, 423.2.1, 423.5; and the Manual of Procedures,

Volume II, Part 3. Bay Area's synthetic minor program amendments were

submitted to EPA by CARB on March 31, 1995. The regulations covered by

this direct final SIP and section 112(l) approval include: Regulation

2, Rule 1, Section 129; and Regulation 2, Rule 6, Sections 232, 234,

310, 311, 403, 404, 420, 421, 422, and 423. For further information,

please see the direct final action which is located in the Final Rules

Section of this Federal Register.
