Approval and Promulgation of

Implementation Plans for Arizona and

California; General Conformity Rules

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Direct final rule.

SUMMARY: This action approves various

revisions to State Implementation Plans

(SIP) which contain regulations for

implementing and enforcing the general

conformity rules which the EPA

promulgated on November 30, 1993.

EPA is approving SIP revisions which

contain general conformity rules for the

Arizona SIP and the California SIP for

the following California Air Pollution

Control Districts (APCD) and Air

Quality Management Districts (AQMD):

El Dorado County APCD, Great Basin

Unified APCD, Monterey Bay Unified

APCD, San Joaquin Valley Unified

APCD, Santa Barbara County APCD,

South Coast AQMD, Feather River

AQMD, Placer County APCD,

Sacramento Metro AQMD, Imperial

County APCD, Bay Area AQMD, San

Diego County APCD, Butte County

AQMD, Ventura County APCD, Mojave

Desert AQMD and Yolo-Solano AQMD.

The approval of these general

conformity rules into the SIP will result

in the SIP criteria and procedures

governing general conformity

determinations instead of the Federal

rules at 40 CFR Part 93, Subpart B for

those actions under the jurisdiction of

the SIPs. Federal actions by the Federal

Highway Administration and Federal

Transit Administration (under Title 23

U.S.C. or the Federal Transit Act) are

covered by the transportation

conformity rules under 40 CFR Part 51,

Subpart T-Conformity to State or

Federal Implementation Plans of

Transportation Plans, Programs, and

Projects Developed, Funded or

Approved Under Title 23 U.S.C. or the

Federal Transit Act (and 40 CFR Part 93,

Subpart A) and are not affected by this

action.

EPA approves these SIP revisions

under sections 110(k) and 176(c) of the

Clean Air Act (CAA or the Act). A more

detailed discussion of this action is

provided below and in the support

documentation.

DATES: This rule is effective on June 22,

1999 without further notice, unless EPA

receives adverse comments by May 24,

1999. If EPA receives such comment, it

will publish a timely withdrawal in the

Federal Register informing the public

that this rule will not take effect.

SUPPLEMENTARY INFORMATION:

I. Background

Section 176(c) of the Act requires that

all Federal actions conform to an

applicable implementation plan.

Conformity is defined in section 176(c)

of the Act as conformity to the SIP’s

purpose of eliminating or reducing the

severity and number of violations of the

National Ambient Air Quality Standards

and achieving expeditious attainment of

such standards, and that such activities

will not: (1) Cause or contribute to any

new violation of any standard in any

area, (2) increase the frequency or

severity of any existing violation of any

standard in any area, or (3) delay timely

attainment of any standard or any

required interim emission reductions or

other milestones in any area.

As required by section 176(c) of the

Act, EPA published the final general

conformity rules implementing this

statutory section on November 30, 1993

(58 FR 63214), which are codified under

40 CFR part 51 subpart W—Determining

Conformity of General Federal Actions

to State or Federal Implementation

Plans. Among other things, EPA’s

general conformity rules require the

States and local air quality agencies

(where applicable) to adopt and submit

a general conformity SIP revision to

EPA which are ‘‘no less stringent than

the requirements’’ of Subpart W (40 CFR

Part 51.851(b)). See also, § 176(c)(4)(C).

The governors of Arizona and

California submitted SIP revisions in

accordance with 40 CFR part 51, subpart

W that contained general conformity

rules for the following areas on the

following dates summarized below.

II. EPA Evaluation and Final Action

EPA compared each of the submitted

rules to the Federally promulgated rule

at 40 CFR part 51. EPA believes that all

of the submitted SIP revisions are

consistent with 40 CFR 51.851(b) and

are no less stringent than the Federal

rule. EPA is thus approving the above

rules into the SIP under 110(k) and

176(c) of the CAA. A more detailed

discussion of EPA’s evaluation can be

found in the Support Documentation

available at the EPA Region 9 Office.

EPA is publishing these rules without

prior proposal because the EPA views

this as a noncontroversial amendment

and anticipates no adverse comments.

However, in the proposed rules section

of this Federal Register publication,

EPA is publishing a separate document

that will serve as the proposal to

approve the SIP revisions should

adverse comments be filed. These rules

will be effective June 22, 1999 without

further notice unless the Agency

receives adverse comments by May 24,

1999.

If the EPA receives any adverse

comments, then EPA will publish a

timely withdrawal of this direct final

rule in the Federal Register informing

the public that the rule will not take

effect. All public comments received

will then be addressed in a subsequent

final rule based on the proposed rule.

The EPA will not institute a second

comment period on this rule. Any

parties interested in commenting on this

rule should do so at this time. If no such

comments are received, the public is

advised that this rule will be effective

on June 22, 1999 and no further action

will be taken on the proposed rule.

Nothing in this action should be

construed as permitting or allowing or

establishing a precedent for any future

request for revision to any state

implementation plan. Each request for

revision to the state implementation

plan shall be considered separately in

light of specific technical, economic,

and environmental factors and in

relation to relevant statutory and

regulatory requirements.

III. Administrative Requirements

A. Executive Order 12866

The Office of Management and Budget

(OMB) has exempted this regulatory

action from Executive Order (E.O.)

12866, Regulatory Planning and Review.

B. Executive Order 12875

Under Executive Order 12875,

Enhancing the Intergovernmental

Partnership, EPA may not issue a

regulation that is not required by statute

and that creates a mandate upon a State,

local or tribal government, unless the

Federal government provides the funds

necessary to pay the direct compliance

costs incurred by those governments, or

EPA consults with those governments. If

EPA complies by consulting, Executive

Order 12875 requires EPA to provide to

the Office of Management and Budget a

description of the extent of EPA’s prior

consultation with representatives of

affected State, local and tribal

governments, the nature of their

concerns, copies of any written

communications from the governments,

and a statement supporting the need to

issue the regulation. In addition,

Executive Order 12875 requires EPA to

develop an effective process permitting

elected officials and other

representatives of State, local and tribal

governments ‘‘to provide meaningful

and timely input in the development of

regulatory proposals containing

significant unfunded mandates.’’

Today’s rule does not create a mandate

on State, local or tribal governments.

The rule does not impose any

enforceable duties on these entities.

Accordingly, the requirements of

section 1(a) of E.O. 12875 do not apply

to this rule.

C. Executive Order 13045

Protection of Children from

Environmental Health Risks and Safety

Risks (62 FR 19885, April 23, 1997),

applies to any rule that: (1) Is

determined to be ‘‘economically

significant’’ as defined under E.O.

12866, and (2) concerns an
19918 Federal Register / Vol. 64, No. 78 / Friday, April 23, 1999 /Rules and Regulations

environmental health or safety risk that

EPA has reason to believe may have a

disproportionate effect on children. If

the regulatory action meets both criteria,

the Agency must evaluate the

environmental health or safety effects of

the planned rule on children, and

explain why the planned regulation is

preferable to other potentially effective

and reasonably feasible alternatives

considered by the Agency. This rule is

not subject to E.O. 13045 because it does

not involve decisions intended to

mitigate environmental health or safety

risks.

D. Executive Order 13084

Under Executive Order 13084,

Consultation and Coordination with

Indian Tribal Governments, EPA may

not issue a regulation that is not

required by statute, that significantly or

uniquely affects the communities of

Indian tribal governments, and that

imposes substantial direct compliance

costs on those communities, unless the

Federal government provides the funds

necessary to pay the direct compliance

costs incurred by the tribal

governments, or EPA consults with

those governments. If EPA complies by

consulting, Executive Order 13084

requires EPA to provide to the Office of

Management and Budget, in a separately

identified section of the preamble to the

rule, a description of the extent of EPA’s

prior consultation with representatives

of affected tribal governments, a

summary of the nature of their concerns,

and a statement supporting the need to

issue the regulation. In addition,

Executive Order 13084 requires EPA to

develop an effective process permitting

elected officials and other

representatives of Indian tribal

governments ‘‘to provide meaningful

and timely input in the development of

regulatory policies on matters that

significantly or uniquely affect their

communities.’’ Today’s rule does not

significantly or uniquely affect the

communities of Indian tribal

governments. Accordingly, the

requirements of section 3(b) of E.O.

13084 do not apply to this rule.

E. Regulatory Flexibility Act

The Regulatory Flexibility Act (RFA)

generally requires an agency to conduct

a regulatory flexibility analysis of any

rule subject to notice and comment

rulemaking requirements unless the

agency certifies that the rule will not

have a significant economic impact on

a substantial number of small entities.

Small entities include small businesses,

small not-for-profit enterprises, and

small governmental jurisdictions. This

final rule will not have a significant

impact on a substantial number of small

entities because SIP approvals under

section 110 and subchapter I, part D of

the Clean Air Act do not create any new

requirements but simply approve

requirements that the State is already

imposing. Therefore, because the

Federal SIP approval does not create

any new requirements, I certify that this

action will not have a significant

economic impact on a substantial

number of small entities. Moreover, due

to the nature of the Federal-State

relationship under the Clean Air Act,

preparation of flexibility analysis would

constitute Federal inquiry into the

economic reasonableness of state action.

The Clean Air Act forbids EPA to base

its actions concerning SIPs on such

grounds. Union Electric Co., v. U.S.

EPA, 427 U.S. 246, 255–66 (1976); 42

U.S.C. 7410(a)(2).

F. Unfunded Mandates

Under Section 202 of the Unfunded

Mandates Reform Act of 1995

(‘‘Unfunded Mandates Act’’), signed

into law on March 22, 1995, EPA must

prepare a budgetary impact statement to

accompany any proposed or final rule

that includes a Federal mandate that

may result in estimated annual costs to

State, local, or tribal governments in the

aggregate; or to private sector, of $100

million or more. Under Section 205,

EPA must select the most cost-effective

and least burdensome alternative that

achieves the objectives of the rule and

is consistent with statutory

requirements. Section 203 requires EPA

to establish a plan for informing and

advising any small governments that

may be significantly or uniquely

impacted by the rule.

EPA has determined that the approval

action promulgated does not include a

Federal mandate that may result in

estimated annual costs of $100 million

or more to either State, local, or tribal

governments in the aggregate, or to the

private sector. This Federal action

approves pre-existing requirements

under State or local law, and imposes

no new requirements. Accordingly, no

additional costs to State, local, or tribal

governments, or to the private sector,

result from this action.

G. Submission to Congress and the

Comptroller General

The Congressional Review Act, 5

U.S.C. 801 et seq., as added by the Small

Business Regulatory Enforcement

Fairness Act of 1996, generally provides

that before a rule may take effect, the

agency promulgating the rule must

submit a rule report, which includes a

copy of the rule, to each House of the

Congress and to the Comptroller General

of the United States. EPA will submit a

report containing this rule and other

required information to the U.S. Senate,

the U.S. House of Representatives, and

the Comptroller General of the United

States prior to publication of the rule in

the Federal Register. This rule is not a

‘‘major’’ rule as defined by 5 U.S.C.

804(2).

H. Petitions for Judicial Review

Under section 307(b)(1) of the Clean

Air Act, petitions for judicial review of

this action must be filed in the United

States Court of Appeals for the

appropriate circuit by June 22, 1999.

Filing a petition for reconsideration by

the Administrator of this final rule does

not affect the finality of this rule for the

purposes of judicial review nor does it

extend the time within which a petition

for judicial review may be filed, and

shall not postpone the effectiveness of

such rule or action. This action may not

be challenged later in proceedings to

enforce its requirements. (See section

307(b)(2).)

the CAA must also be controlled at

existing sources in the same source

category. Also, section 129 of the CAA

specifically addresses solid waste

combustion. It requires EPA to establish

emission guidelines (EG) for MWC units

and requires states to develop state

plans for implementing the promulgated

EG. The part 60, subpart Cb, EG for

MWC units differ from other EG

adopted in the past because the rule

addresses both sections 111(d) and 129

CAA requirements. Section 129

requirements override certain related

aspects of section 111(d).
