Clean Air Act Approval and Promulgation of State Implementation
Plans; Connecticut: PM10 Prevention of Significant Deterioration
Increments; and Approval of a Second 1-Year Extension of PM10
Attainment Date for New Haven
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is fully approving a State Implementation Plan (SIP)
revision submitted by the State of Connecticut, which replaces the
total suspended particulate (TSP) prevention of significant (PSD)
increments with increments for PM10 (particulate matter with an
aerodynamic diameter less than or equal to a nominal 10 micrometers).
EPA is also fully approving Connecticut's request for a second 1-year
extension of the attainment date for the New Haven PM10 nonattainment
area, based on monitored air quality data for the national ambient air
quality standard for PM10 during the years 1993-95. These actions are
being taken under the Clean Air Act.
DATES: This action is effective on May 27, 1997, unless adverse or
critical comments are received by April 25, 1997. If the effective date
is delayed, timely notice will be published in the Federal Register.
ADDRESSES: Comments may be mailed to Susan Studlien, Deputy Director,

SUPPLEMENTARY INFORMATION:
I. Background
PM10 PSD Increments
Section 107(d) of the 1977 Amendments to the Clean Air Act
authorized each State to submit to the Administrator a list identifying
those areas which (1) do not meet a national ambient air quality
standard (NAAQS) (nonattainment areas), (2) cannot be classified on the
basis of available ambient data (unclassifiable areas), and (3) have
ambient air quality levels better than the NAAQS (attainment areas). In
1978, the EPA published the original list of all area designations
pursuant to section 107(d)(2) (commonly referred to as ``Section 107
areas''), including those designations for total suspended particulates
(TSP), in 40 CFR Part 81.
One of the purposes stated in the Act for the Section 107 areas is
for implementation of the statutory requirements for PSD. The PSD
provisions of Part C of the Act generally apply in all Section 107
areas that are designated attainment or unclassifiable [40 CFR
52.21(i)(3)]. Under the PSD program, the air quality in an attainment
or unclassifiable area is not allowed to deteriorate beyond prescribed
maximum allowable increases in pollutant concentrations (i.e.,
increments).
EPA revised the primary and secondary NAAQS for particulate matter
on July 1, 1987 (52 FR 24634), eliminating TSP as the indicator for the
NAAQS and replacing it with the PM10 indicator. However, EPA did not
delete the Section 107 areas for TSP listed in 40 CFR Part 81 at that
time because there were no increments for PM10 promulgated at that
time.1 States were required to continue implementing the TSP
increments in order to prevent significant deterioration of particulate
matter air quality until the PM10 increments replaced the TSP
increments.
---------------------------------------------------------------------------
\1\ The EPA did not promulgate new PM10 increments
simultaneously with the promulgation of the PM10 NAAQS. Under
Sec. 166(b) of the Act, EPA is authorized to promulgate new
increments ``not more than 2 years after the date of promulgation of
* * * standards.'' Consequently, EPA temporarily retained the TSP
increments, as well as the Section 107 areas for TSP.
---------------------------------------------------------------------------
EPA promulgated PSD increments for PM10 on June 3, 1993. (See 58 FR
31622-31638.) EPA promulgated revisions to the Federal PSD permitting
regulations in 40 CFR 52.21, as well as the PSD permitting requirements
that State programs must meet in order to be approved into the SIP in
40 CFR 51.166. EPA or States with delegated State programs were
required to begin implementation of the increments by June 3, 1994. The
implementation date for States with SIP-approved PSD permitting
programs (including Connecticut) would be the date on which EPA
approves each revised State PSD program containing the PM10 increments.
In accordance with 40 CFR 51.166(a)(6)(i), each State with SIP-approved
PSD programs was required to adopt the PM10 increment requirements
within nine months of the effective date (or by March 3, 1995).
The PM10 PSD increments were set at the following levels: 4
g/m3 (annual arithmetic mean) and 24 g/m3
(24-hour maximum) for Class I areas, 17 g/m3 (annual
arithmetic mean) and 30 g/m3 (24-hour maximum) for Class
II areas, and 34 g/m3 (annual arithmetic mean) and 60
g/m3 (24-hour maximum) for Class III areas. There are no
Class I or III areas in Connecticut.
The implementation of the PM10 increments will utilize the existing
baseline dates and areas for particulate matter. As such, particulate
matter increments, measured as PM10, already consumed since the
original baseline dates established for TSP will continue to be
accounted for, but all future calculations of the amount of increments
consumed will be based on PM10 emissions beginning on the
implementation date of the PM10 increments (that is, today, the date of
EPA approval for Connecticut). For further information regarding the
PM10 increments, see the June 3, 1993 Federal Register.
The requirements in 40 CFR 51.166 regarding prevention of
significant deterioration consist of three elements. First, the State
must conduct an increment consumption analysis for new major sources
and modifications. Second, the State must review the potential
increment consumption from minor point, area, and mobile source.
Finally, the State must commit to a State implementation plan revision
upon identification of any increment violation. As discussed below,
these requirements have been fulfilled by the State of Connecticut.
Clean Air Act Nonattainment Requirements: EPA Actions Concerning
Designation and Classification
On the date of enactment of the Clean Air Act Amendments of 1990
(`the Act'), PM10 areas meeting the qualifications of Sec. 107(d)(4)(B)
of the Act were designated nonattainment by operation of law. [See
generally, 42 U.S.C. Sec. 7407(d)(4)(B).] These areas included all
former Group I areas and any other areas violating the PM10 standards
prior to January 1, 1989. On October 31, 1990 (55 FR 45799), EPA
redefined a Group I area for Connecticut as the City of New Haven; the
remainder of the state was designated as Group III. Subsequently, after
enactment of the Act on November 15, 1990, New Haven was designated
moderate nonattainment for PM10 in 56 FR 11101 (March 15, 1991). All
other areas not designated nonattainment at enactment were designated
unclassifiable.
States containing areas which were designated as moderate
nonattainment by operation of law under Sec. 107(d)(4)(B) were required
to develop and submit SIPs to provide for the attainment of the PM10
NAAQS. Under section 189(a)(2), those SIP revisions were to be
submitted within 1 year of enactment of the Act (November 15, 1991).
The SIP revisions were to provide for implementation of reasonable
available control measures/technology (RACM/RACT) by December 10, 1993
and attainment of the PM10 NAAQS by December 31, 1994.
Reclassification as Serious Nonattainment
EPA has the responsibility, under sections 179(c) and 188(b)(2) of
the Act, of determining within 6 months after December 31, 1994 whether
initial moderate PM10 nonattainment areas have attained the NAAQS.
Section 179(c)(1) of the Act provides that these determinations are to
be based upon an area's ``air quality as of the attainment date,'' and
section 188(b)(2) is consistent with this requirement. EPA will make
the determinations of whether an area's air quality is meeting the PM10
NAAQS based upon air quality data gathered at monitoring sites in the
nonattainment area and entered into the Aerometric Information
Retrieval System (AIRS). This data will be reviewed to determine the
area's air quality status in accordance with EPA guidance at 40 CFR
Part 50, Appendix K.
According to Appendix K, attainment of the annual PM10 standard is
achieved when the annual arithmetic mean PM10 concentration is equal to
or less than 50 g/m3. Attainment of the
[[Page 14329]]
24-hour standard is determined by calculating the expected number of
exceedences of the 150 g/m3 limit per year. The 24-hour
standard is attained when the expected number of exceedences is 1.0 or
less. A total of 3 consecutive years of clean air quality data is
generally necessary to show attainment of the 24-hour and annual
standards for PM10. A complete year of air quality data, as referred to
in 40 CFR Part 50, Appendix K, is comprised of all 4 calendar quarters
with each quarter containing data from at least 75 percent of the
scheduled sampling days.
Under Sec. 188(b)(2) a moderate area shall be reclassified as
serious by operation of law after the statutory attainment date if the
Administrator determines that the area has failed to attain the NAAQS.
Under section 188(b)(2)(B) of the Act, the EPA must publish a notice in
the Federal Register identifying those areas which failed to attain the
standard and must be reclassified as serious by operation of law.
Application for a 1-year Extension of the Attainment Date
If the State does not have the necessary number of consecutive
clean years of data to show attainment of the NAAQS, a State may apply
for an extension of the attainment date. Pursuant to Sec. 188(d) of the
Act, a State may apply for and EPA may grant a 1-year extension of the
attainment date if the State has: (1) Complied with the requirements
and commitments pertaining to the applicable implementation plan for
the area, and (2) the area has measured no more than 1 exceedence of
the 24-hour PM10 standard in the year preceding the extension year, and
the annual mean concentration of PM10 in the area for such year is less
than or equal to the standard. In addition, as discussed below, the EPA
will consider the state's PM planning progress for the area. If the
State does not have the requisite number of years of clean air quality
data to show attainment and does not apply or does not qualify for an
attainment date extension, the area will be reclassified as serious by
operation of law. Connecticut applied for and was granted a 1-year
extension of the attainment date for New Haven, effective November 11,
1995. (See 60 FR 47097, September 11, 1995.)
If an extension is granted, at the end of the extension year, EPA
will again determine whether the area has attained the PM10 NAAQS. If
the State still does not have 3 consecutive years of clean air quality
data, it may apply for a second 1-year extension of the attainment
date. In order to qualify for the second 1-year extension of the
attainment date, the State must satisfy the same requirements listed
above for the first extension. In addition, EPA will consider the
State's PM10 planning progress for the area in a manner similar to its
evaluation of the first extension request. However, EPA may grant no
more than two 1-year extensions of the attainment date to a single
nonattainment area. [See Section 188(d) of the Act.]
Section 188(d) of the Act provides that the Administrator ``may''
extend the attainment date for areas that meet the minimum requirements
specified above. The provision does not dictate or compel that EPA
grant extensions to such areas. In exercising this discretionary
authority for PM10 nonattainment areas, EPA will examine the air
quality planning progress made in the moderate area. EPA will be
disinclined to grant an attainment date extension unless a State has,
in substantial part, addressed its moderate PM10 planning obligations
for the area. In order to determine whether the State has substantially
met these planning requirements the EPA will review the States
application for the attainment date extension to determine whether the
State has: (1) Adopted and substantially implemented control measures
submitted to address the requirement for implementing RACM/RACT in the
moderate nonattainment area; and (2) that reasonable further progress
is being met for the area. RFP for PM10 nonattainment areas is
determined to be linear emissions reductions made on an annual basis
which will provide progress toward the eventual attainment of the NAAQS
in the area.
Summary of Connecticut's PM10 PSD Increment SIP Revision
In this section, EPA is acting on revisions to the PSD permitting
program for the State of Connecticut. Specifically, Connecticut DEP is
amending Subsection 22a-174-3(k) to replace the TSP increments with the
federal increments for PM10. All other regulations and requirements
necessary for full implementation of the PSD program for PM10 are
already in place.
In accordance with the requirements in 40 CFR 51.66, Connecticut
DEP is also committing to implementation of the following program
elements for the protection of the particulate matter increments:
increment consumption analyses for new major sources and major
modifications; reviews of potential increment consumption from minor
point, area, and mobile sources; and a SIP revision upon identification
of an increment violation. The major source baseline date (January 6,
1975) and the minor source baseline date (established in Connecticut on
June 7, 1988), both for particulate matter measured as TSP, will remain
the same for PM10. All of Connecticut, except the City of New Haven, is
currently considered a Class II attainment area. New Haven is currently
classified as nonattainment for PM10. The PSD program for particulate
matter does not apply to the City of New Haven until that area is
reclassified to attainment. Meanwhile, new major sources or major
modifications proposing to locate in the City of New Haven will be
required to comply with the nonattainment provisions of Subsection 22a-
174-3(l) of the Regulations of Connecticut State Agencies.
Procedural Background Regarding the PM10 PSD Increment SIP Revision
The Act requires States to observe certain procedural requirements
in developing implementation plans and plan revisions for submission to
EPA. Section 110(a)(2) of the Act provides that each implementation
plan submitted by a State must be adopted after reasonable notice and
public hearing. Section 110(l) of the Act similarly provides that each
revision to an implementation plan submitted by a State under the Act
must be adopted by such State after reasonable notice and public
hearing.
EPA also must determine whether a submittal is complete and
therefore warrants further EPA review and action. [See Section
110(k)(1) and 57 13565, April 16, 1992.] The EPA's completeness
criteria for SIP submittals are set out at 40 CFR Part 51, Appendix V.
The EPA attempts to make completeness determinations within 60 days of
receiving a submission. However, a submittal is deemed complete by
operation of law under Section 110(k)(a)(B) if a completeness
determination is not made by EPA within six months after receipt of the
submission.
The State of Connecticut held a public hearing on August 23, 1994
to entertain public comment on the PSD SIP revision. On January 13,
1995, the Commissioner of the Connecticut Department of Environmental
Protection (the Governor's designee) submitted revisions to Subsection
22a-174-3(k) of the Regulations of Connecticut Agencies to incorporate
the federal PM10 PSD increments into the SIP and insure that all
elements for the federal PSD program for particulate matter are
adopted.
EPA reviewed to Connecticut DEP's SIP revision to determine
completeness
[[Page 14330]]
shortly after their submittal, in accordance with the completeness
criteria referenced above. In a letter dated March 28, 1995, EPA-Region
1 informed the Connecticut Governor's designee that the submittal was
determined complete and explained how the review and approval process
would proceed.
Summary of Connecticut's Extension Request
On March 22, 1996, the Connecticut Department of Environmental
Protection (Connecticut DEP) submitted a request for second 1-year
extension of the attainment date for the New Haven initial moderate
PM10 nonattainment area.
EPA's Air Quality Strategies and Standards Division (AQSSD) has
prepared a guidance titled ``Criteria for Granting 1-Year Nonattainment
Area Attainment Dates, Making Attainment Determinations, and Reporting
on Quantitative Milestones'' (November 14, 1994 memorandum from AQSSD
Director Sally Shaver) which outlines how to assess the adequacy of
requests for a 1-year extension of the attainment date. The rationale
for EPA's approval action are detailed in the Technical Support
Document (TSD), dated May 10, 1996. In summary, Connecticut has
fulfilled the specific elements of the Clean Air Act and that guidance
as follows:
Upon application by any state, EPA may extend for one additional
year if the State fulfilled two requirements under section 188 (d) of
the Clean Air Act. First, a state must have complied with all
requirements and commitments pertaining to the area in the applicable
implementation plan. Secondly, no more than one exceedance of the 24
hour standard can occur in the area in the year proceeding the
extension year, and the annual mean concentration of PM10 in the area
for such year must be less than or equal to the standard level.
Connecticut has fulfilled these two basic requirements.
Connecticut is implementing the EPA-approved PM10 SIP.
Connecticut's PM10 attainment plan and contingency measures were
approved by EPA on September 11, 1995 (60 FR 47076). Connecticut's
PM10 attainment plan demonstrated that the implementation of RACM
was sufficient to attain and maintain the PM10 NAAQS. Furthermore,
Connecticut has demonstrated that RACT/RACM, embodied in 7 consent
orders, have been adopted and submitted in the form of a SIP revision
and are being implemented for New Haven. New Haven has monitored no
more than 1 exceedence during 1995, the year preceding the extension
year.2 Connecticut's extension request states that indeed the area
recorded no exceedences of the PM10 NAAQS in 1995, and is complying
with the applicable state implementation plan. Furthermore, real
emissions reductions have been achieved.3
---------------------------------------------------------------------------
\2\ Section 189(c) requires that Part D SIPs include
quantitative milestones to document RFP towards attainment. Every 3
years until EPA redesignates an area to attainment, States must
report on whether milestones have been met. Connecticut's SIP
commits CT DEP to submit quantitative milestone and RFP reports to
EPA every 3 years. For initial moderate PM10 nonattainment
areas, the emissions reductions made between SIP submittal and the
attainment date will satisfy the first quantitative milestone. (See
General Preamble 57 FR 13539.) Since EPA believes it is reasonable
to key the first milestone to the SIP revision containing control
measures which will result in emission reductions and since the
PM10 attainment date was less than 3 years from the actual
submittal date of CT DEP's SIP revision, CT DEP submitted--and EPA
is accepting--the emissions reductions associated with the New Haven
PM10 Attainment Plan SIP revision (approved by EPA effective
November 11, 1995) as meeting RFP and the first quantitative
milestone for New Haven. (See TSD dated May 10, 1996.)
\3\ A review of the PM10 air quality data for New Haven
shows air quality monitors for this area monitored 4 exceedences of
the 24-hour PM10 NAAQS during the 3-year period from 1993 to
1995. All exceedences occurred in 1993 at the Yankee Gas monitor
site (AIRS Site ID 09-009-0021). The area did not have any
exceedences of the PM10 NAAQS in 1995.
---------------------------------------------------------------------------
In addition to meeting the two statutory requirements, Connecticut
has made the planning progress required by EPA guidance. Connecticut
has demonstrated that RACT/RACM, embodied in 7 consent orders, have
been adopted and submitted in the form of a SIP revision and are being
implemented for New Haven. Furthermore, real emissions reductions have
been achieved.
For further details regarding Connecticut's extension request and
how it meets EPA's requirements, the reader should refer to the TSD
dated May 10, 1996, on file at EPA's Region I office (contact listed
above).
II. Final Action
EPA is approving the SIP revision regarding PM10 PSD
permitting and the second 1-year extension of the PM10 attainment
date for New Haven, as submitted by the State of Connecticut.
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 May 27, 1997 unless, by April 25, 1997, 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 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 May 27, 1997.
Nothing in this action should be construed as permitting or
allowing or establishing a precedent for any future request for
revision to any State implementation plan. Each request for revision to
the State implementation plan shall be considered separately in light
of specific technical, economic, and environmental factors and in
relation to relevant statutory and regulatory requirements.
III. Administrative Requirements
A. Executive Order 12866
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 Nichols, Assistant Administrator for
Air and Radiation. The Office of Management and Budget (OMB) has
exempted this regulatory action from E.O. 12866 review.
B. Regulatory Flexibility Act
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 sections 110 and 301, 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, I certify
that it does not have a significant impact on any small entities
affected. Moreover, due to the nature of the
[[Page 14331]]
Federal-State relationship under the CAA, preparation of a 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).
C. 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.
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, EPA 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).
E. 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 May 27, 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).) 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.
