[CT060-7219a; A-1-FRL-6479-4]
Approval and Promulgation of Air Quality Implementation Plans;
Connecticut; Removal of Oxygenated Gasoline Requirement for the
Connecticut Portion of the New York-N. New Jersey-Long Island Area (the
``Southwest Connecticut Area'')
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: In today's action, EPA is approving a State Implementation
Plan (SIP) revision under the Clean Air Act submitted by the State of
Connecticut on October 7, 1999 to remove Connecticut's oxygenated
gasoline program as a carbon monoxide control (CO) measure from the
SIP. The SIP revision includes revised regulations adopted by
Connecticut which redefine the control period for oxygenated gasoline
in southwest Connecticut such that the oxygenated gasoline program is
not required to be implemented except in the unlikely event of a
violation of the CO standard in the area. EPA supports this regulatory
amendment since it is consistent with the CO redesignation and
maintenance plan for the southwest Connecticut area that EPA approved
on March 10, 1999 (64 FR 12005).
DATES: This direct final rule is effective on January 31, 2000 without
further notice, unless EPA receives adverse comment by January 3, 2000.
If adverse comment is received, EPA will publish a timely withdrawal of
the direct final rule in the Federal Register and inform the public
that the rule will not take effect.

Conclusion
What Action Is EPA Taking Today?
On October 7, 1999, the State of Connecticut submitted a formal
revision to its SIP removing the oxygenated gasoline program as a CO
control measure for the southwest Connecticut area. In the CO
redesignation published on March 10, 1999 (64 FR 12005), EPA agreed
that Connectocut's CO SIP does not rely on the oxygenated gasoline
program to maintain the CO National Ambient Air Quality Standard
(NAAQS) in the southwest Connecticut area.
Under Clean Air Act section 211(m), 42 U.S.C. 7545(m), States with
certain CO nonattainment areas are required to implement oxygenated
gasoline programs. Once such an area subsequently attains the CO NAAQS,
oxygenated gasoline requirements may be removed if it is demonstrated
that the program is not needed to maintain attainment in that area. See
Clean Air Act section 110(l), 42 U.S.C. 7410(l). CO concentrations
throughout the New York City area (which includes the southwest
Connecticut area) have been below the CO NAAQS for more than four
years, and the CO NAAQS has not been exceeded in southwest Connecticut
since 1985.
Through the use of EPA's MOBILE computer model and air quality
dispersion modeling, it has been determined that the oxygenated
gasoline program no longer needs to be implemented to maintain
attainment of the CO NAAQS. The CO NAAQS will not be violated in the
future if the program is removed as a control strategy. Improved CO
levels are attributable primarily to three sources of emission
reductions: (1) turnover of vehicle fleets in the area to more
sophisticated cleaner technology vehicles; (2) implementation of
reformulated gasoline year round; and (3) the recent implementation of
the enhanced vehicle inspection and maintenance (I/M) program in
Connecticut. This modeling supports the conclusion that the area will
remain well below the NAAQS without the wintertime oxygenated gasoline
program in place.
What Is the Oxygenated Gasoline Program and How Does It Apply to
Connecticut?
The oxygenated gasoline program is designed to reduce CO pollution
from gasoline powered vehicles including passenger cars, sport utility
vehicles and light trucks, which are significant contributors of CO
emissions. Inhaling CO inhibits the blood's capacity to carry oxygen to
organs and tissues. Persons with heart disease, infants, elderly
persons, and individuals with respiratory diseases are particularly
sensitive to CO. Effects of CO on healthy adults include impaired
exercise capacity, visual perception, manual dexterity, learning
functions, and ability to perform complex tasks.
On March 3, 1978, (43 FR 8962), EPA published a rulemaking that set
forth the attainment status for all States in relation to the NAAQS.
The Connecticut portion of the New York--N. New Jersey-Long Island area
was designated as nonattainment for CO through this notice.
The Clean Air Act sets forth a number of SIP requirements for
States with areas designated as nonattainment for the CO NAAQS. Section
211(m) of the Clean Air Act requires States with CO nonattainment
areas, having design values of 9.5 parts per million (ppm) CO or above
for any two-year period after 1989, to implement oxygenated gasoline
programs. The requirement for an oxygenated gasoline program is to
apply during the high CO season, which is generally during the colder
winter
[[Page 67189]]
months when cars tend to have higher tailpipe CO emissions. Oxygenated
gasoline programs require that, during the high CO season, gasoline
contain at least 2.7% oxygen by weight. This requirement was intended
to assure more complete gasoline combustion, thus achieving a reduction
in tailpipe emissions.
The requirement for an oxygenated gasoline program applies to
southwest Connecticut because this area is included in the New York
City CO nonattainment area which had a design value for CO above 9.5
ppm. In a letter to EPA dated March 14, 1991, the Connecticut
Department of Environmental Protection (CTDEP) recommended that the
southwest Connecticut area be classified as moderate nonattainment for
CO based on monitoring data measured outside the Connecticut portion of
the nonattainment area, which includes the aforementioned parts of New
York State and New Jersey. Therefore, although the southwest
Connecticut area was attaining the standard prior to 1990, the area had
to implement the oxygenated gasoline program as part of the New York-N.
New Jersey-Long Island Area. The municipalities included in the
Connecticut area are Bethel, Bridgeport, Bridgewater, Brookfield,
Danbury, Darien, Easton, Fairfield, Greenwich, Monroe, New Canaan, New
Fairfield, New Milford, Newtown, Norwalk, Redding, Ridgefield, Sherman,
Stamford, Stratford, Trumbull, Weston, Westport, and
Wilton.1 EPA also determined that oxygenated gasoline must
contain a minimum oxygen content of 2.7 percent by weight of oxygen,
specific labeling requirements, and enforcement procedures (57 FR 47849
(October 20, 1992)).
---------------------------------------------------------------------------
\1\ Because Clean Air Act section 211(m) applies to the larger
of the Consolidated Metropolitan Statistical Areas (CMSA) or the
metropolitan statistical area in which the nonattainment area is
located, the oxygenated gasoline requirement for the area applies
throughout the larger CMSA.
---------------------------------------------------------------------------
On September 30, 1994, Connecticut submitted to EPA its oxygenated
gasoline program contained in section 22a-174-28 of the Regulations of
Connecticut State Agencies, entitled ``Oxygenated gasoline.'' EPA
approved this submittal as it applies to southwest Connecticut on July
25, 1996 (61 FR 38574), thereby satisfying the requirements of section
211(m) of the Clean Air Act. This action also defined the control
period (i.e, the period that oxygenated gasoline must be sold in the
area) to be the four month period from November 1 through the last day
of February.
What Is the Purpose and Content of Connecticut's SIP Revision?
Connecticut submitted an oxygenated gasoline SIP revision to EPA on
October 7, 1999. The submittal revised the SIP to remove Connecticut's
oxygenated gasoline program as a CO control measure. The SIP revision
documents that the Connecticut Department of Environmental Protection
held a public hearing on August 5, 1999 to take comment on the State's
proposed rulemaking to remove the State requirements for its oxygenated
gasoline program in Connecticut. The rulemaking was adopted by the
State of Connecticut on September 28, 1999, and submitted to EPA as a
formal SIP revision on October 7, 1999.
The 1990 Clean Air Act required areas to achieve the CO standard by
December 31, 1995, and the Connecticut area has measured no violations
of the CO standard since 1985. This area was allowed to redesignate
based on the entire area attaining, and the southwest Connecticut area
was redesignated to attainment on March 10, 1999 (64 FR 12005). As a
result of the redesignation to attainment, the area became eligible to
drop the oxygenated gasoline requirement and convert it to a
contingency measure. Removal of the oxygenated gasoline program is
supported by the State's demonstration that the area is attaining the
CO NAAQS and will continue to attain even without implementation of the
oxygenated gasoline program. EPA supports this regulatory amendment
since it is consistent with the CO redesignation and maintenance plan
for the southwest Connecticut area that EPA approved on March 10, 1999
(64 FR 12005).
On September 9, 1999 (64 FR 48974), EPA approved the removal of the
oxygenated gasoline program for the New Jersey portion of the CO
control area. The submittal from New Jersey contained an analysis of
multi-state air quality and impacts of oxygenated gasoline removal
which confirmed that the area will continue to attain the CO NAAQS with
the removal of oxygenated gasoline. In addition, the CO redesignation
submitted by Connecticut on May 29, 1998 and approved by EPA on March
10, 1999 (64 FR 12005) also demonstrated that removing oxygenated
gasoline in Connecticut would have inconsequential impact on the other
two states CO attainment.
Based on EPA's determination that the entire CMSA is attaining the
CO NAAQS, EPA is approving Connecticut's SIP revision, submitted on
October 7, 1999, to remove the State's oxygenated gasoline program and
convert it to a contingency measure in the CO SIP.
How Have the Criteria for Removing Oxygenated Gasoline Been Met?
The entire New York-N. New Jersey-Long Island area (which includes
the southwest Connecticut area) has attained the CO NAAQS since 1995.
In 1994, New Jersey experienced two violations of the CO NAAQS that
were recorded at monitoring stations in North Bergen and Elizabeth in
Northern New Jersey. Since 1995, no subsequent violations were recorded
in Northern New Jersey. Since 1994, no violations of the CO NAAQS were
recorded in the New York portion of the area, and southwest Connecticut
area has not had an exceedance of the standard since 1985.2
---------------------------------------------------------------------------
\2\ An exceedance occurs when an average CO concentration
greater than or equal to 9.5 ppm is recorded over an eight-hour
period. A violation occurs when two non-overlapping exceedances are
recorded at the same monitoring site during the same calendar year.
---------------------------------------------------------------------------
Two CO monitors meeting EPA siting criteria are maintained in the
southwest Connecticut portion of the New York City CO nonattainment
area. Locations for these monitors were selected to assure good
representation of both CO exposure to people and the maximum CO
concentrations which would occur, and were placed in the cities of
Bridgeport and Stamford.
Monitoring data from these locations are collected and quality-
assured in accordance with 40 CFR part 58. In accordance with EPA's
protocol for determining CO exceedances, the following table lists the
second highest recorded CO concentrations, in ppm, at each monitoring
station for the calendar years 1994 through 1998:

------------------------------------------------------------------------
Prior to today's action, EPA approved the redesignation of the
southwest Connecticut portion of the New York City CO nonattainment
area (64 FR 12005, March 10, 1999). As part of its action to approve
Connecticut's redesignation, EPA also approved the maintenance
demonstration for southwest Connecticut. Furthermore, EPA has also
determined that CO
[[Page 67190]]
maintenance is demonstrated in southwest Connecticut without reliance
on oxygenated gasoline implementation. Connecticut has demonstrated
that any increase in CO emissions that might result from removing the
oxygenated gasoline requirement will not contribute to CO emissions
that exceed the CO emissions budget EPA approved in Connecticut's
maintenance plan. In addition, the redesignation included an analysis
of the impacts that removing the Connecticut program would have on New
York and New Jersey, and these impacts were deemed inconsequential.
Additional detail on the CO maintenance demonstration analysis for
Connecticut can be found at 63 FR 58637 (November 2, 1998) and 64 FR
12005 (March 10, 1999).
Based on EPA's determination that the entire area is attaining the
CO NAAQS and will continue to meet the standard even without the
oxygenated gasoline program, EPA is approving Connecticut's SIP
revision, submitted on October 7, 1999, which removes the State's
oxygenated gasoline requirement program from its CO SIP.
What Is the Contingency Plan for Carbon Monoxide?
In the March 10, 1999 Federal Register (64 FR 12005), EPA
determined, through Connecticut's use of EPA's MOBILE computer model
and air quality dispersion modeling, that the oxygenated gasoline
program is no longer necessary for Connecticut because it has been
demonstrated that the CO NAAQS will not be violated anywhere in the
CMSA if the program is removed. Furthermore, since the area was
redesignated to attainment for CO, Connecticut is no longer required to
implement the oxygenated gasoline program but must keep it in the SIP
as a contingency measure. See Clean Air Act section 175A(d), 42 U.S.C.
7505a(d). However, the State is required to implement the maintenance
plan approved into the SIP on March 10, 1999.
Connecticut developed a three-stage contingency plan for the
southwest Connecticut area to be implemented in the unlikely event of
an exceedance. The State will implement contingency measures when a CO
exceedance occurs even though they are only required if a violation
occurs, therefore making the continency plan more stringent than is
required (again, see March 10, 1999 redesignation at 64 FR 12005). As
mentioned earlier, an exceedance occurs when a monitor measures CO
levels of 9.5 parts per million as a mean concentration over an eight-
hour period. If this were to occur, the first stage of the plan is to
investigate the local traffic conditions where the exceedance occurred.
The second stage is the implementation of the enhanced inspection and
maintenance program, and the third is the low emission vehicle program
(both are already being implemented for ground-level ozone purposes.)
The State believes that an early trigger (an exceedance rather than
violation) will allow Connecticut to take early measures in response to
the emission problem to avoid another exceedance and/or persistence of
a problem that could lead to a NAAQS violation.
Connecticut's revised ``Oxygenated gasoline'' regulation contained
in section 22a-174-28 of the Regulations of Connecticut State Agencies
only applies if a violation of the CO standard (the NAAQS is violated
if there are two or more exceedances in a given year) is recorded.
Therefore, the oxygenated gasoline program essentially becomes a fourth
contingency measure for the southwest Connecticut area. See the
technical support document and the March 10, 1999 Federal Register for
more information on CO contingency measures.
Conclusion
EPA has determined that the southwest Connecticut CO nonattainment
area has attained the CO National Ambient Air Quality Standard and can
maintain attainment without the continued implementation of its
oxygenated gasoline program. As a consequence of this determination,
EPA is approving Connecticut's October 7, 1999 SIP revision to remove
the State's oxygenated gasoline program requirement from the federally
approved State Implementation Plan and convert it to a contingency
measure.
II. Final Action
EPA is approving removal of oxygenated gasoline requirement for the
Connecticut portion of the New York-N. New Jersey-Long Island Area. The
Agency has reviewed this request for revision of the federally-approved
State implementation plan for conformance with the provisions of the
1990 Clean Air Act Amendments enacted on November 15, 1990. EPA is also
making a minor technical correction to the Code of Federal Regulations
to remove a CO attainment date extension that is no longer relevant to
the State.
The EPA is publishing this action without prior proposal because
the Agency 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 revision should
relevant adverse comments be filed. This rule will be effective January
31, 2000 without further notice unless the Agency receives relevant
adverse comments by January 3, 2000.
If the EPA receives such comments, then EPA will publish a notice
withdrawing the final rule and 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 the proposed rule. Only 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 rule
will be effective on January 31, 2000 and no further action will be
taken on the proposed rule.
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, entitled
``Regulatory Planning and Review.''
B. Executive Orders on Federalism
Executive Order 13132 on Federalism (64 FR 43255, August 10, 1999)
revokes and replaces Executive Orders 12612 (Federalism) and 12875
(Enhancing the Intergovernmental Partnership). Executive Order 13132
requires EPA to develop an accountable process to ensure ``meaningful
and timely input by State and local officials in the development of
regulatory policies that have federalism implications.'' ``Policies
that have federalism implications'' is defined in the Executive Order
to include regulations that have ``substantial direct effects on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government.'' Under Executive Order 13132, EPA may
not issue a regulation that has federalism implications, that imposes
substantial direct compliance costs, and that is not required by
statute, unless the Federal government provides the funds necessary to
pay the direct compliance costs incurred by State and local
governments, or EPA consults with State and local officials early in
the process of developing the proposed regulation. EPA also may not
issue a regulation that has federalism
[[Page 67191]]
implications and that preempts State law unless the Agency consults
with State and local officials early in the process of developing the
proposed regulation.
This final rule will not have substantial direct effects on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government, as specified in Executive Order 13132.
Thus, the requirements of section 6 of the Executive Order 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
Executive Order 12866, and (2) concerns an 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 Executive Order 13045 because it does
not involve decisions intended to mitigate environmental health or
safety risks.
D. Executive Order 13084
Under Executive Order 13084, EPA may not issue a regulation that is
not required by statute, that significantly affects 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. This action does not involve
or impose any requirements that affect Indian Tribes. Accordingly, the
requirements of section 3(b) of Executive Order 13084 do not apply to
this rule.
E. Regulatory Flexibility
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 sections 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
costs to state, local, or tribal governments in the aggregate; or to
the 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 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. National Technology Transfer and Advancement Act
Section 12 of the National Technology Transfer and Advancement Act
(NTTAA) of 1995 requires Federal agencies to evaluate existing
technical standards when developing a new regulation. To comply with
NTTAA, EPA must consider and use ``voluntary consensus standards''
(VCS) if available and applicable when developing programs and policies
unless doing so would be inconsistent with applicable law or otherwise
impractical.
The EPA believes that VCS are inapplicable to this action. Today's
action does not require the public to perform activities conducive to
the use of VCS.
I. 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 January 31, 2000. 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
[[Page 67192]]
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).) EPA encourages interested parties to comment in response to
the proposed rule rather than petition for judicial review, unless the
objection arises after the comment period allowed for in the proposal.
