ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[IN79-1A; FRL-5848-4]


Approval and Promulgation of State Implementation Plan; Indiana

AGENCY: Environmental Protection Agency.

ACTION: Direct final rule.

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

SUMMARY: The United States Environmental Protection Agency (USEPA) is 
approving a February 5, 1997, request from Indiana, for a State 
Implementation Plan (SIP) revision for the Vanderburgh County ozone 
nonattainment area. The revision is for a transportation control 
measure (TCM) to reduce the emissions of volatile organic compounds 
(VOCs) from motor vehicles by converting city-owned vehicles to 
compressed natural gas as a fuel. Reductions in VOCs help protect the 
public's health and welfare by reducing ground level ozone, commonly 
known as urban smog. High concentrations of ground level ozone can 
aggravate asthma, cause inflammation of lung tissue, decrease lung 
function, and impair the body's defenses against respiratory infection.

DATES: This ``direct final'' rule is effective on August 25, 1997, 
unless USEPA receives written comments that are adverse or critical by 
July 28, 1997. If the effective date is delayed, timely notice will be 
published in the Federal Register.

ADDRESSES: Copies of the documents relevant to this action are 
available for inspection during normal business hours at the following 
location: Regulation Development Section, Air Programs Branch, (AR-
18J), U.S. Environmental Protection Agency, Region 5, 77 West Jackson 
Boulevard, Chicago, Illinois, 60604.

SUPPLEMENTARY INFORMATION:

I. Background

    Section 108(e) of the Clean Air Act, as amended in 1990 (Act), 
provides for transportation-air quality planning guidance for the 
development and implementation of transportation and other measures 
necessary to demonstrate and maintain attainment of national ambient 
air quality standards. Section 108(f)(1)(A) provides a list of 
transportation control measures with emission reduction potential. The 
USEPA has further provided guidance in the final report entitled 
Transportation Control Measures: State Implementation Plan Guidance 
dated September 1990; and also in Transportation Control Measure 
Information Documents dated March 1992.
    Section 108(f)(1)(A) of the Act lists sixteen TCMs for 
consideration by States and planning agencies to use to reduce 
emissions and help attain and maintain the national ambient air quality 
standards. Programs to reduce motor vehicle emissions consistent with 
title II of the Act are listed in section 108(f)(1)(A)(xii).

II. Evaluation of the State Submittal

    On February 5, 1997, Indiana submitted to the USEPA a SIP revision 
request for Vanderburgh County Transportation Control Measures, 
specifically, a fleet conversion request. A public hearing was held on 
March 12, 1997, and documentation on the public hearing was submitted 
to complete the SIP revision request. The SIP submission was found to 
be complete by the USEPA in a letter dated April 3, 1997.
    The TCM for Vanderburgh County is the conversion of 40-60 city-
owned vehicles from using gasoline as a fuel to compressed natural gas. 
This project is consistent with the title II provisions in section 241 
for clean-fuel vehicles, and is thus consistent with section 
108(f)(1)(A)(xii) as a program to reduce motor vehicle emissions. 
Vanderburgh County is currently designated as marginal nonattainment 
for ozone, but can adopt any and all measures to help reduce ozone 
precursor pollutants and thus attain and maintain the ozone ambient air 
quality standard. This TCM is consistent with the measures provided in 
section 108(f)(1)(A)(xii) of the Act.
    The project was formally endorsed by the Evansville Urban 
Transportation Study (EUTS) Board at its June 18, 1996, public meeting. 
EUTS is seeking Congestion Mitigation and Air Quality (CMAQ) funds for 
the project from the Department of Transportation, to be matched with 
local money.
    The SIP revision request provides an estimate of the emission 
reduction for a fuel conversion of 40 light duty vehicles from the city 
and county fleets to compressed natural gas. The air quality benefits 
are estimated utilizing emission test results from the California Air 
Resources Board and, assuming that each vehicle will average 20,000 
miles of use per year with a five year life cycle. The estimated air 
quality benefit is calculated as 0.141 tons per year of hydrocarbon 
emissions, 1.225 tons per year of carbon monoxide emissions, and 0.194 
tons per year of oxides of nitrogen

[[Page 34407]]

emissions. These pollutants are precursors of ground level ozone or 
smog, and reductions in precursors will reduce the concentrations of 
ground level ozone.
    The SIP revision request thus meets the requirements for a TCM, as 
defined in section 108 of the Act, and meets the requirements for 
emission reductions to help attain and maintain the national ambient 
air quality standards.
    As an approved TCM in the SIP for Vanderburgh County, this TCM will 
need to be included in the transportation improvement program and 
transportation plan for the area, and tracked and reported for 
conformity purposes. The requirements for transportation conformity 
cannot be met unless TCMs in the approved SIP for the area are 
proceeding according to schedule.

III. USEPA Action

    The USEPA approves Indiana's February 5, 1997, SIP revision request 
to implement the transportation control measure of fleet conversion of 
city and county vehicles (at least 40) to compressed natural gas as a 
fuel.
    The USEPA is publishing this action without prior proposal because 
USEPA views this as a noncontroversial revision and anticipates no 
adverse comments. However, in a separate document in this Federal 
Register publication, the USEPA is proposing to approve the SIP 
revision should adverse or critical written comments be filed. This 
action will be effective on August 25, 1997, unless, by July 28, 1997, 
adverse or critical written comments on the approval are received.
    If the USEPA receives adverse written comments, the approval will 
be withdrawn before the effective date by publishing a subsequent 
rulemaking that will withdraw the final action. All written public 
comments received will be addressed in a subsequent final rule based on 
this action serving as a proposed rule. The USEPA will not institute a 
second comment period on this action. Any parties interested in 
commenting on this action should do so at this time. If no such 
comments are received, the public is advised that this action will be 
effective on August 25, 1997.
    Nothing in this action should be construed as permitting, allowing 
or establishing a precedent for any future request for revision to any 
SIP. Each request for revision to the SIP shall be considered 
separately in light of specific technical, economic, and environmental 
factors and in relation to relevant statutory and regulatory 
requirements.

IV. Administrative Requirements

A. Executive Order 12866

    This action has been classified as a Table 3 action for signature 
by the Regional Administrator under the procedures published in the 
Federal Register on January 19, 1989 (54 FR 2214-2225), as revised by a 
July 10, 1995, memorandum from Mary D. Nichols, Assistant Administrator 
for Air and Radiation. The Office of Management and Budget (OMB) has 
exempted this regulatory action from Executive Order 12866 review.

B. Regulatory Flexibility

    Under the Regulatory Flexibility Act, 5 U.S.C. section 600 et seq., 
USEPA must prepare a regulatory flexibility analysis assessing the 
impact of any proposed or final rule on small entities. 5 U.S.C. 
sections 603 and 604. Alternatively, USEPA may certify that the rule 
will not have a significant impact on a substantial number of small 
entities. Small entities include small businesses, small not-for-profit 
enterprises, and government entities with jurisdiction over populations 
of less than 50,000.
    SIP approvals under section 110 and subchapter I, part D of the 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 impose any new requirements, the Administrator 
certifies that it does not have a significant impact on any small 
entities affected. Moreover, due to the nature of the Federal-State 
relationship under the Act, preparation of a flexibility analysis would 
constitute Federal inquiry into the economic reasonableness of the 
State action. The Clean Air Act forbids USEPA to base its actions 
concerning SIPs on such grounds. Union Electric Co. v. EPA., 427 U.S. 
246, 256-66 (1976); 42 U.S.C. 7410(a)(2).

C. Unfunded Mandates

    Under section 202 of the Unfunded Mandates Reform Act of 1995, 
signed into law on March 22, 1995, USEPA must undertake various actions 
in association with any proposed or final rule that includes a Federal 
mandate that may result in estimated costs to state, local, or tribal 
governments in the aggregate; or to the private sector, of $100 million 
or more. 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 the private 
sector, result from this action.

D. Submission to Congress and the General Accounting Office

    Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business 
Regulatory Enforcement Fairness Act of 1996, USEPA submitted 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 
General Accounting Office prior to publication of the rule in today's 
Federal Register. This rule is not a major rule as defined by 5 U.S.C. 
804(2).

F. Petitions for Judicial Review

    Under section 307(b)(1) of the Act, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by August 25, 1997. 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)).
