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.
