40 CFR Part 52

[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.
