Clean Air Act Approval and

Promulgation of Revisions to

Prevention of Significant Deterioration

of Air Quality Regulations

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Proposed rule.

SUMMARY: The EPA proposes to approve

the State Implementation Plan (SIP)

submitted by the State of Mississippi to

include modifications of the state

prevention of significant deterioration of

air quality regulation to update the

adoption by reference in Regulation

APC–S–5, of the amendments and

revisions to the federal regulations

promulgated in 40 CFR 52.21 and

51.166 as of the date of State adoption

of this revision. In the final rules section

of this Federal Register, the EPA 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

description of the revision and a more

detailed rationale for the approval is set

forth in the direct final rule, and the

public should refer to that notice for

more information. If no adverse

comments are received in response to

that direct final rule, no further activity

is contemplated in relation to this

proposed rule. 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withdrawn and all public comments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.

DATES: To be considered, comments

must be received by June 5, 1995.

ADDRESSES: Written comments should

be addressed to: Kimberly Bingham,

Approval and Promulgation of

Implementation Plans and Designation

of Areas for Air Quality Planning

Purposes: State of Ohio

AGENCY: United States Environmental

Protection Agency (USEPA).

ACTION: Proposed rule.

SUMMARY: The USEPA proposes to

approve the redesignation request and

maintenance plan for the DaytonSpringfield, Ohio area as a revision to

Ohio’s State Implementation Plan (SIP)

for ozone. In the final rules section of

this Federal Register, the USEPA is

approving the State’s redesignation

request and maintenance plan as a

direct final rule without prior proposal

because USEPA 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 in

response to the direct final rule, no

further activity is contemplated in

relation to this proposed rule. If USEPA

receives comments adverse to or critical

of the approval, USEPA will withdraw

the approval before its effective date by

publishing a subsequent Federal

Register document which withdraws

the direct final rule. All public

comments received will then 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 action must be

received by June 5, 1995.

Approval and Promulgation of

Implementation plans and Designation

of Areas for Air Quality Planning

Purposes; Ohio

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Proposed rule.

SUMMARY: The Ohio U.S. Environmental

Protection Agency (USEPA) has

requested the redesignation of the

Cincinnati area (Hamilton, Clermont,

Butler, and Warren Counties) from

moderate nonattainment to attainment

for ozone; and Clinton County from

transitional nonattainment to

attainment. The requests were received

on November 15, 1994. Before the

Cincinnati request can be approved

through final rulemaking, several State

Implementation Plan (SIP) revisions

must be approved. The USEPA is

separately rulemaking on Ohio SIP

revisions involving volatile organic

compounds (VOC) Reasonable Available

Control Technology (RACT) rules, the

1990 Base-year Inventory, the section

182(f) nitrogen oxides (NOX) RACT

waiver request, the 182(b)(1) reasonable

further progress plan, and the 182(b)(4)

inspection and maintenance plan. Upon

final approval of these plans, the

Cincinnati nonattainment area will have

met all of the requirements for

redesignation specified under section

107(d)(3)(E). The approval of the

Clinton County request is not contingent

upon separate rulemaking action by

USEPA. The USEPA is proposing

approval of the redesignation request

and maintenance plan for Butler,

Hamilton, Warren, Clermont, and

Clinton Counties in Ohio.

DATES: Comments on this redesignation

and on the proposed USEPA action

must be received by June 5, 1995.

ADDRESSES: Written comments should

be addressed to: William L. MacDowell,

Chief, Regulation Development Section,

SUPPLEMENTARY INFORMATION:

I. Summary of State Submittal

The Ohio Environmental Protection

Agency (OEPA) has requested the

redesignation of the Ohio portion of the

Cincinnati Area (including the counties

of Hamilton, Clermont, Butler, and

Warren) from nonattainment to

attainment for ozone. The Cincinnati

moderate nonattainment area also

includes the Kentucky counties of

Boone, Campbell, and Kenton. These

counties are being addressed in separate

rulemaking. The OEPA is also

requesting the redesignation of Clinton

county from transitional nonattainment

to attainment. The USEPA received both

requests for redesignation to attainment

on November 15, 1994. Public hearing

and response to comment information

was received on February 24, 1995.

Under Section 107(d) of the 1977

amended Clean Air Act, the USEPA

promulgated the ozone attainment

status for each geographic area of the

country. All counties in the Cincinnati

area were designated as an ozone

nonattainment area in March 1978 (43

FR 8962). On November 15, 1990, the

Clean Air Act Amendments of 1990

(CAAA) were enacted. Pursuant to

Section 107(d)(4)(A), Butler, Clermont,

Hamilton, and Warren Counties were

designated as moderate nonattainment

areas, as a result of monitored violations

of the ozone National Ambient Air

Quality Standards (NAAQS) during the

summer of 1988 (56 FR 56694,

November 6, 1991). Clinton County did

not experience a violation during the

three year period from January 1, 1987

through December 31, 1989, and

therefore, pursuant to section 185(A) of

the CAAA, was designated as a

transitional nonattainment area. A

review of the Cincinnati area

redesignation request is presented

below, followed by a review of the

Clinton County request.

II. Redesignation Review Criteria

The CAAA provides the requirements

for redesignating a nonattainment area

to attainment. Specifically, Section

107(d)(3)(E) provides for redesignation

if: (i) The Administrator determines that

the area has attained the National

Ambient Air Quality Standard

(NAAQS); (ii) The Administrator has

fully approved the applicable

implementation plan for the area under

Section 110(k); (iii) The Administrator

determines that the improvement in air

quality is due to permanent and

enforceable reductions in emissions

resulting from implementation of the

applicable implementation plan and

applicable Federal air pollutant control

regulations and other permanent and

enforceable reductions; (iv) The

Administrator has fully approved a

maintenance plan for the area as

meeting the requirements of Section

175(A); and (v) The State containing

such area has met all requirements

applicable to the area under Section 110

and Part D.

The USEPA provided guidance on

redesignation in the General Preamble

for the Implementation of Title I of the

Clean Air Act Amendments of 1990, 57

FR 13498 (April 16, 1992),

supplemented at 57 FR 18070 (April 28,

1992). Three key memoranda provide

further guidance with respect to section

107(d)(3)(E) of the amended Act. The

first, dated September 4, 1992, was

issued by John Calcagni, Director, Air

Quality Management Division, Subject:

Procedures for Processing Requests to

Redesignate Areas to Attainment

(Calcagni Memorandum). The second,

dated September 17, 1993, was issued

by Michael Shapiro, Acting Assistant

Administrator for Air and Radiation,

Subject: State Implementation Plan (SIP)

Requirements for Area Submitting

Requests for Redesignation to

Attainment of the Ozone and Carbon

Monoxide (CO) NAAQS on or after

November 15, 1992 (Shapiro

Memorandum). The third, dated

October 14, 1994, was issued by Mary

Nichols, Assistant Administrator for Air

and Radiation, Subject: Part D New

Source Review Requirements for Areas

Requesting Redesignation to Attainment

(Nichols Memorandum).

A. The Area Must Have Attained the

For ozone, an area may be considered

attaining the NAAQS if there are no
