Approval and Promulgation of Implementation Plans and Designation 
of Areas for Air Quality Planning Purposes; State of Connecticut

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: On September 30, 1994, the Connecticut Department of 
Environmental Protection (CT DEP), submitted a request to redesignate 
the Hartford/New Britain/Middletown area from nonattainment to 
attainment for carbon monoxide (CO). Under the Clean Air Act as amended 
in 1990 (CAA), designations can be revised if sufficient data is 
available to warrant such revisions. In this action, EPA is approving 
the Connecticut request because it meets the redesignation requirements 
set forth in the CAA.
    In addition, EPA is approving two related State Implementation Plan 
(SIP) submissions by Connecticut DEP. On January 12, 1993, Connecticut 
DEP submitted a final 1990 base year emission inventory for CO 
emissions, which includes emissions data for all sources of CO in 
Connecticut's two CO nonattainment areas (the Hartford/New Britain/
Middletown area and the Connecticut portion of the New York/New Jersey/
Connecticut Consolidated Metropolitan Statistical Area (CMSA). On 
January 12, 1993, January 14, 1993, September 30, 1994 and August 1, 
1995, Connecticut DEP submitted an oxygenated fuel program and 
revisions for both CO nonattainment areas. In this action, EPA is 
approving the CO emissions inventory for both areas and the oxygenated 
fuels program only as it applies to the Hartford/New Britain/Middletown 
nonattainment area.

DATES: This final rule will be effective January 2, 1996 unless 
critical or adverse comments are received by November 30, 1995. If the 
effective date is delayed, timely notice will be published in the 
Federal Register.

ADDRESSES: Written comments should be sent to Susan Studlien, Acting 
Director, at the EPA Regional Office listed below. Copies of the 
redesignation request and the State of Connecticut's submittals are 
available for public review during normal business hours at the 
addresses listed below.

SUPPLEMENTARY INFORMATION:

I. Background

    On March 31, 1978, (See 43 FR 8962), EPA published rulemaking which 
set forth attainment status for all States in relation to the National 
Ambient Air Quality Standards (NAAQS). The area of Hartford/New 
Britain/Middletown (the ``Hartford area'') was designated as 
nonattainment for Carbon Monoxide through this rulemaking notice. In a 
letter dated March 14, 1991 from the Connecticut Department of 
Environmental Protection to EPA Administrator, the State recommended 
that the area be classified as Category 3 nonattainment. Because the 
area had a design value of 9.7 ppm, the area was considered 
``moderate'' nonattainment under the provisions outlined in sections 
186 and 187 of the CAA. (See 56 FR 56694 (Nov. 6, 1991) and 57 FR 56762 
(Nov. 30, 1992), codified at 40 CFR part 81, Sec. 81.307.). The CAA 
established an attainment date of December 31, 1995, for all moderate 
CO areas. The Hartford area has ambient monitoring data showing 
attainment of the CO NAAQS, since 1988. Therefore, in an effort to 
comply with the CAA and to ensure continued attainment of the NAAQS, on 
September 30, 1994 the State of Connecticut submitted a CO 
redesignation request and a maintenance plan for the Hartford area. 
Connecticut submitted evidence that a public hearing was held on August 
17, 1994.

II. Evaluation Criteria

    Section 107(d)(3)(E) of the 1990 Clean Air Act Amendments provides 
five specific requirements that an area must meet in order to be 
redesignated from nonattainment to attainment.
    1. The area must have attained the applicable NAAQS;
    2. The area must have a fully approved SIP under section 110(k) of 
CAA;
    3. The air quality improvement must be permanent and enforceable;
    4. The area must have a fully approved maintenance plan pursuant to 
section 175A of the CAA;
    5. The area must meet all applicable requirements under section 110 
and Part D of the CAA.

III. Review of State Submittal

    On October 28, 1994, Region I determined that the information 
received from the CT DEP constituted a complete redesignation request 
under the general completeness criteria of 40 CFR part 51, appendix V, 
Secs. 2.1 and 2.2.
    The Connecticut redesignation request for the Hartford/New Britain/
Middletown area meets the five requirements of section 107(d)(3)(E), 
noted above. The following is a brief description of how the State has 
fulfilled each of these requirements.

1. Attainment of the CO NAAQS

    Connecticut has quality-assured CO ambient air monitoring data 
showing that the Hartford area has met the CO NAAQS. The Connecticut 
request is based on an analysis of quality-assured monitoring data 
which is relevant to the maintenance plan and to the redesignation 
request. To attain the CO NAAQS, an area must have complete quality-
assured data showing no more than one exceedance of the standard over 
at least two consecutive years. The ambient air CO monitoring data for 
calendar year 1989 through calendar year 1993, relied upon by 
Connecticut in its redesignation request, shows no violations of the CO 
NAAQS in the Hartford area. The most recent ambient CO data shows no 
exceedances in the calendar year 1994 and one exceedance 

[[Page 55317]]
in calendar year 1995 (on January 13, 1995). Because the area has 
complete quality assured data showing no more than one exceedance of 
the standard per year over at least two consecutive years (1991 and 
1992), the area has met the first statutory criterion of attainment of 
the CO NAAQS (40 CFR 50.9 and appendix C). Connecticut has committed to 
continue monitoring in this area in accordance with 40 CFR part 58.
    Connecticut used EPA's ``Guideline for Modeling Carbon Monoxide 
from Roadway Intersections'' to select six ``hot-spot'' intersections 
for detailed analysis. Once the intersections were selected, 
evaluations for CO levels for existing and future year conditions were 
performed using the MOBILE5A emission model and the CAL3QHC (version 
2.0) dispersion model. These modeling results show no violations for 
1993 or future year (2005) of the NAAQS for CO.

2. Fully Approved SIP

    Connecticut's CO SIP is fully approved by EPA as meeting all the 
requirements of Section 110 of the Act, including the requirement in 
Section 110(a)(2)(I) to meet all the applicable requirements of Part D 
(relating to nonattainment), which were due prior to the date of 
Connecticut's redesignation request. Connecticut's 1982 CO SIP was 
fully approved by EPA in 1984 as meeting the CO SIP requirements in 
effect under the CAA at that time. The 1990 CA required that CO 
nonattainment areas achieve specific new requirements depending on the 
severity of the nonattainment classification. Requirements for the 
Hartford area include the preparation of a 1990 emission inventory with 
periodic updates, adoption of an oxygenated fuels program, and 
development of conformity procedures. Each of these requirements, added 
by the 1990 Amendments to the CAA, are discussed in greater detail 
below.
    Consistent with the October 14, 1994 EPA guidance from Mary D. 
Nichols entitled ``Part D New Source Review (part D NSR) Requirements 
for Areas Requesting Redesignation to Attainment,'' EPA is not 
requiring as a prerequisite to redesignation to attainment EPA's full 
approval of a part D NSR program by Connecticut. Under this guidance, 
nonattainment areas may be redesignated to attainment notwithstanding 
the lack of a fully-approved part D NSR program, so long as the program 
is not relied upon for maintenance. Connecticut has not relied on a NSR 
program for CO sources to maintain attainment. Although EPA is not 
treating a part D NSR program as a prerequisite for redesignation, it 
should be noted that EPA is in the process of taking final action on 
the State's revised NSR regulation, which does include requirements for 
CO nonattainment areas. Because the Hartford area is being redesignated 
to attainment by this action, Connecticut's Prevention of Significant 
Deterioration (PSD) requirements will be applicable to new or modified 
sources in the Hartford area.
    A. Emission Inventory--Connecticut submitted its base year 
inventory to EPA on January 13, 1994, which included estimates for CO 
in the Hartford-New Britain-Middletown area and the New York-New 
Jersey-Connecticut area, as required under section 187(a)(1) of the 
CAA. EPA is approving the CO portion of the inventory for both area 
with this redesignation request.
    Section 172(c)(3) of the CAA requires that nonattainment plan 
provisions include a comprehensive, accurate, and current inventory of 
actual emissions from all sources of relevant pollutants in the 
nonattainment area. Connecticut included the requisite inventory in the 
CO SIP. The base year for the inventory was 1990, using a three month 
CO season of November 1990 through January 1991. Stationary point 
sources, stationary area sources, on-road mobile sources, and nonroad 
mobile sources of CO were included in the inventory. Stationary sources 
with emissions of greater than 100 tons per year were also included in 
the inventory.
    The following list presents a summary of the CO peak season daily 
emissions estimates in tons per day by source category: Point Sources, 
28.91 tons per day; Area Sources, 498.05 tons per day; Mobile On-Road 
Sources, 1497.03 tons per day; Mobile Nonroad Sources, 221.36 tons per 
day; Total Sources, 2245.35 tons per day. Available guidance for 
preparing emission inventories is provided in the General Preamble (57 
FR 13498, April 16, 1992).
    Section 110(k) of the CAA sets out provisions governing the EPA's 
review of base year emission inventory submittals in order to determine 
approval or disapproval under section 187(a)(1). The EPA is granting 
approval of the Connecticut 1990 base year CO emissions inventory 
submitted on January 13, 1994, based on the 1993. At the time of 
submission of the redesignation request for the Hartford area, 
Connecticut submitted revisions to its oxygenated fuel regulation 
specifying that the oxygenated fuel requirement in the Hartford CMSA 
will not be implemented except as a contingency measure in the area's 
maintenance plan. On August 1, 1995, Connecticut submitted another 
revision to its oxygenated fuel regulations changing the CO control 
period in the Connecticut portion of the New York/New Jersey/
Connecticut CMSA from seven to four months. As part of this action, EPA 
is approving Connecticut's oxygenated fuel program except as it applies 
to the Connecticut portion of the NJ-NY-CT CMSA (the Southwestern 
Control Area). EPA will address the Southwestern Control Area 
definition and that area's control period as part of a separate action.
    The oxygenated gasoline program is one in which all oxygenated 
gasoline must contain a minimum oxygen content of 2.7 percent by weight 
of oxygen. Under Section 211(m)(4) of the CAA, EPA also issued 
requirements for the labeling of gasoline pumps used to dispense 
oxygenated gasoline, as well as guidelines on the establishment of an 
appropriate control period. These labeling requirements and control 
period guidelines may be found in at 57 FR 47849, dated October 20, 
1992. Connecticut's oxygenated gasoline regulation requires the minimum 
2.7 percent oxygen content in gasoline sold in the Central Control and 
Southwestern Control Areas. The regulation also contains the necessary 
labeling regulations, enforcement procedures, and oxygenate test 
methods. For a more detailed description of the manner in which 
Connecticut's oxygenated fuels program meets the requirements of 
Section 211(m) of the CAA, the reader is referred to the Technical 
Support Document, which is available for review at the addresses 
provided above.
    Connecticut has chosen to convert its oxygenated fuels requirement 
in the Hartford CMSA to a contingency measure in its maintenance plan 
upon redesignation. Connecticut's oxygenated fuels regulation provides 
that oxygenated gasoline is only required in the Hartford CMSA if a CO 
violation is monitored in the area. Because Connecticut attained the CO 
standard based on data before the oxygenated fuel program was 
implemented in the Hartford CMSA, oxygenated gasoline was not necessary 
to reach attainment. In its demonstration of maintenance, described 
below, the State has shown that oxygenated gasoline in the Hartford 
CMSA is not necessary for continued maintenance of the CO NAAQS. 
Consequently, by this action, EPA is both approving Connecticut's 
oxygenated fuels regulation and simultaneously approving its use as a 
contingency measure for the Hartford area.
    The State of Connecticut has adopted an Oxygenated Fuel Program 
that covers 

[[Page 55318]]
the Connecticut portion of the New Jersey-New York-Connecticut 
Consolidated Metropolitan Statistical Area (CMSA) and the Hartford 
CMSA. In this action, the EPA is approving the oxygenated fuel program, 
Connecticut's Regulation 22a-174-28, only as it applies to the Hartford 
CMSA. The control period for the program is from November 1 to the last 
day of February for the Central Control Area (Hartford CMSA) if a 
violation of the ambient air quality standard for carbon monoxide 
occurs within the control area after November 1, 1993. EPA will address 
the Southwestern Control Area separately.
    C. Conformity--Under section 176(c) of the CAA, states were 
required to submit revisions to their SIPs that include criteria and 
procedures to ensure that Federal actions conform to the air quality 
planning goals in the applicable SIPs. The requirement to determine 
conformity applies to transportation plans, programs and projects 
developed, funded or approved under Title 23 U.S.C. or the Federal 
Transit Act (``transportation conformity''), as well as all other 
Federal actions (``general conformity''). Congress provided for the 
State revisions to be submitted one year after the date of promulgation 
of final EPA conformity regulations. EPA promulgated final 
transportation conformity regulations on November 24, 1993 (58 FR 
62188) and final general conformity regulations on November 30, 1993 
(58 FR 63214). These conformity rules require that the States adopt 
both transportation and general conformity provisions in the SIP for 
areas designated nonattainment or subject to a maintenance plan 
approved under CAA section 175A. Pursuant to Sec. 51.396 of the 
transportation conformity rule, the State of Connecticut is required to 
submit a SIP revision containing transportation conformity criteria and 
procedures consistent with those established in the Federal rule by 
November 25, 1994. Similarly, pursuant to Sec. 51.851 of the general 
conformity rule, Connecticut was required to submit a SIP revision 
containing general conformity criteria and procedures consistent with 
those established in the Federal rule by December 1, 1994. Connecticut 
has not yet submitted either of these conformity SIP revisions.
    Although Connecticut has not yet adopted and EPA approved 
conformity SIP revisions, EPA may approve this redesignation request. 
EPA interprets the requirement of a fully approved SIP in section 
107(d)(3)(v) to mean that, for a redesignation request to be approved, 
the State must have met all requirements that become applicable to the 
subject area prior to or at time of the submission of the redesignation 
request. Because Connecticut submitted its redesignation request on 
October 20, 1994, prior to the due dates for conformity, it is not 
necessary that the State have an approved conformity SIP prior to 
redesignation. It should be noted that approval of Connecticut's 
redesignation request does not obviate the need for Connecticut to 
submit the required conformity SIPs to EPA.

3. Improvement in Air Quality Due to Permanent and Enforceable Measures

    EPA approved Connecticut's CO SIP, submitted in 1982, under the 
CAA, as amended in 1977. Emission reductions achieved through the 
implementation of control measures contained in that SIP are 
enforceable. These measures were: transportation plan reviews, a basic 
Inspection and Maintenance Program, right turn on red, and the Federal 
Motor Vehicle Control Program. As discussed above, the State initially 
attained the NAAQS in 1989 with monitored attainment through 1993. This 
indicates that the improvements are due to the permanent and 
enforceable measures contained in the 1982 CO SIP.
    The State of Connecticut has demonstrated that actual enforceable 
emission reductions are responsible for the air quality improvement and 
that the CO emissions in the base year are not artificially low due to 
local economic downturn. EPA finds that the combination of certain 
existing EPA-approved SIP and federal measures contribute to the 
permanence and enforceability of reduction in ambient CO levels that 
have allowed the area to attain the NAAQS.

4. Fully Approved Maintenance Plan Under Section 175A

    Section 175A of the CAA sets forth the elements of a maintenance 
plan for areas seeking redesignation from nonattainment to attainment. 
The plan must demonstrate continued attainment of the applicable NAAQS 
for at least ten years after the Administrator approves a redesignation 
to attainment. Eight years after the redesignation, the state must 
submit a revised maintenance plan which demonstrates attainment for the 
ten years following the initial ten-year period. To provide for the 
possibility of future NAAQS violations, the maintenance plan must 
contain contingency measures, with a schedule for implementation 
adequate to assure prompt correction of any air quality problems. In 
this notice, EPA is approving the State of Connecticut's maintenance 
plan for the Hartford/New Britain/Middletown area because EPA finds 
that Connecticut's submittal meets the requirements of section 175A.
A. Attainment Emission Inventory
    As previously noted, on January 13, 1994, the State of Connecticut 
submitted a comprehensive inventory of CO emissions from the Hartford/
New Britain/Middletown area. The inventory includes emissions from 
area, stationary, and mobile sources using 1990 as the base year for 
calculations.
    The 1990 inventory is considered representative of attainment 
conditions because the NAAQS was not violated during 1990. The State 
submittal contains the detailed inventory data and summaries by county 
and source category. The comprehensive base year emissions inventory 
was submitted in the National Emission Data System format. Finally, 
this inventory was prepared in accordance with EPA guidance. It also 
contains summary tables of the 1990 base year and was projected to the 
year 2005.

[[Page 55319]]


B. Demonstration of Maintenance-Projected Inventories
    Total CO emissions were projected from 1990 base year out to 2005. 
These projected inventories were prepared in accordance with EPA 
guidance. Connecticut will not implement the oxygenated fuel program in 
Hartford CMSA unless a violation is measured. The projections show that 
calculated CO emissions, assuming no oxygenated fuels program after 
1993, are not expected to exceed the level of the base year inventory 
during this time period. Therefore, it is anticipated that Hartford/New 
Britain/Middletown will maintain the CO standard without the oxygenated 
fuel program.
C. Verification of Continued Attainment
    Continued attainment of the CO NAAQS in the Hartford/New Britain/
Middletown area depends, in part, on the State's efforts toward 
tracking indicators of continued attainment during the maintenance 
period. The State has also committed to submit periodic inventories of 
CO emissions every three years.
D. Contingency Plan
    The level of CO emissions in the Hartford/New Britain/Middletown 
area will largely determine its ability to stay in compliance with the 
CO NAAQS in the future. Despite the State's best efforts to demonstrate 
continued compliance with the NAAQS, the ambient air pollutant 
concentrations may exceed or violate the NAAQS. Also, section 175A(d) 
of the CAA requires that the contingency provisions include a 
requirement that the State implement all measures contained in the SIP 
prior to redesignation. Therefore, Connecticut has provided contingency 
measures with a schedule for implementation in the event of a future CO 
air quality problem. The plan contains triggering mechanisms to 
determine when contingency measures are needed.
    Connecticut has developed a two-stage contingency plan. The first 
stage is the implementation of an enhanced I/M program. The second 
stage is the implementation of an oxygenated fuels program throughout 
the Hartford CMSA. The CMSA includes several municipalities outside the 
nonattainment area. Therefore, a oxygenated fuels program will provide 
reductions from vehicles which originate outside the nonattainment area 
but travel within it.
    In order to be an adequate maintenance plan, the plan should 
include at least one contingency measure that will go into effect with 
a triggering event. Connecticut is relying largely on a contingency 
measure that will go into effect regardless of any triggering event, 
namely, enhanced Inspection and Maintenance. Connecticut has one 
measure that will not go into effect unless a triggering event occurs, 
namely oxygenated fuels.
E. Subsequent Maintenance Plan Revisions
    In accordance with section 175A(b) of the CAA, the State has agreed 
to submit a revised maintenance SIP eight years after the area is 
redesignated to attainment. Such revised SIP will provide for 
maintenance for an additional ten years.

5. Meeting Applicable Requirements of Section 110 and Part D

    In Section III.2. above, EPA sets forth the basis for its 
conclusion that Connecticut has a fully approved SIP which meets the 
applicable requirements of Section 110 and Part D of the CAA.

Final Action

    EPA is approving the Hartford/New Britain/Middletown CO maintenance 
plan because it meets the requirements set forth in section 175A of the 
CAA. In addition, the Agency is approving the request to redesignate 
the Hartford/New Britain/Middletown CO area to attainment, because the 
State has demonstrated compliance with the requirements of section 
107(d)(3)(E) for redesignation. 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 a separate document in this Federal Register publication, 
the EPA is proposing to approve the SIP revision should adverse or 
critical comments be filed. This action will be effective January 2, 
1996 unless, by November 30, 1995, adverse or critical comments are 
received. If the EPA receives such comments, this action will be 
withdrawn before the effective date by publishing a subsequent document 
that will withdraw the final action. All public comments received will 
then be addressed in a subsequent final rule based on this action 
serving as a proposed rule. The EPA 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 January 2, 1996.
    Nothing in this action should be construed as permitting or 
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.
    The CO SIP is designed to satisfy the requirements of part D of the 
CAA and to provide for attainment and maintenance of the CO NAAQS. This 
final redesignation should not be interpreted as authorizing the State 
to delete, alter, or rescind any of the CO emission limitations and 
restrictions contained in the approved CO SIP. Changes to CO SIP 
regulations rendering them less stringent than those contained in the 
EPA approved plan cannot be made unless a revised plan for attainment 
and maintenance is submitted to and approved by EPA. Unauthorized 
relaxations, deletions, and changes could result in both a finding of 
non-implementation (section 179(a) of the CAA) and in a SIP deficiency 
call made pursuant to sections 110(a)(2)(H) and 110(k)(2) of the CAA.
    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA 
must prepare a regulatory flexibility analysis assessing the impact of 
any proposed or final rule on small entities. 5 U.S.C. 603 and 604. 
Alternatively, EPA 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 
CAA 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, it does not have any 
economic impact on any small entities. Redesignation of an area to 
attainment under section 107(d)(3)(E) of the CAA does not impose any 
new requirements on small entities.
    Redesignation is an action that affects the status of a 
geographical area and does not impose any regulatory requirements on 
sources. Accordingly, I certify that the approval of the redesignation 
request will not have an impact on any small entities.

Unfunded Mandates

    Under Sections 202, 203, and 205 of the Unfunded Mandates Reform 
Act of 1995 (``Unfunded Mandates Act''), signed into law on March 25, 
1995, EPA must undertake various actions in association with proposed 
or final rules that include a Federal mandate that may 

[[Page 55320]]
result in estimated costs of $100 million or more to the private 
sector, or to State, local, or tribal governments in the aggregate.
    Through submission of this state implementation plan or plan 
revision, the State and any affected local or tribal governments have 
elected to adopt the program provided for under section 175A and 
section 187(a)(1) of the Clean Air Act. The rules and commitments 
approved in this action may bind State, local and tribal governments to 
perform certain actions and also may ultimately lead to the private 
sector being required to certain duties. To the extent that the 
imposition of any mandate upon the State, local or tribal governments 
either as the owner or operator of a source or as mandate upon the 
private sector, EPA's action will impose no new requirements under 
State law; such sources are already subject to these requirements under 
State law. Accordingly, no additional costs to State, local, or tribal 
governments, or to the private sector, results from this action. EPA 
has also determined that this final action does not include a mandate 
that may result in estimated costs of $100 million or more to State, 
local, or tribal governments in the aggregate or to the private sector.

Sec. 52.376  Control strategy: Carbon Monoxide.

    (a) Approval-On January 12, 1993, the Connecticut Department of 
Environmental Protection submitted a revision to the carbon monoxide 
State Implementation Plan for the 1990 base year emission inventory. 
The inventory was submitted by the State of Connecticut to satisfy 
Federal requirements under section 182(a)(1) of the Clean Air Act as 
amended in 1990, as a revision to the carbon monoxide State 
Implementation Plan.
    (b) Approval-On September 30, 1994, the Connecticut Department of 
Environmental Protection submitted a request to redesignate the 
Hartford/New Britain/Middletown Area carbon monoxide nonattainment area 
to attainment for carbon monoxide. As part of the redesignation 
request, the State submitted a maintenance plan as required by 175A of 
the Clean Air Act, as amended in 1990. Elements of the section 175A 
maintenance plan include a base year (1993 attainment year) emission 
inventory for carbon monoxide, a demonstration of maintenance of the 
carbon monoxide NAAQS with projected emission inventories to the year 
2005 for carbon monoxide, a plan to verify continued attainment, a 
contingency plan, and an obligation to submit a subsequent maintenance 
plan revision in 8 years as required by the Clean Air Act. If the area 
records a violation of the carbon monoxide NAAQS (which must be 
confirmed by the State), Connecticut will implement one or more 
appropriate contingency measure(s) which are contained in the 
contingency plan. The menu of contingency measure includes enhanced 
motor vehicle inspection and maintenance program and implementation of 
the oxygenated fuels program. The redesignation request and maintenance 
plan meet the redesignation requirements in sections 107(d)(3)(E) and 
175A of the Act as amended in 1990, respectively. The redesignation 
meets the Federal requirements of section 182(a)(1) of the Clean Air 
Act as a revision to the Connecticut Carbon Monoxide State 
Implementation Plan for the above mentioned area.
