SUPPLEMENTARY INFORMATION:

Background

Clean Air Act Requirements and EPA Actions Concerning Designation and 
Classification

    On the date of enactment of the Clean Air Act Amendments of 1990 
(herein after referred to as ``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 USC section 
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 Sec. 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 Secs. 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 
Sec. 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 24-hour standard 
is determined by calculating the expected number of exceedances of the 
150 g/m3 limit per year. The 24-hour standard is attained 
when the expected number of exceedances 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 Sec. 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 exceedance 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. 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.
    Section 188(d) of the Act provides that the Administrator ``may'' 
extend 

[[Page 47098]]
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.
    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 Sec. 188(d) of the Act].

Summary of Connecticut's Extension Request

    On March 31, 1995, the Connecticut Department of Environmental 
Protection (Connecticut DEP) submitted a request for a 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 June 13, 1995. In summary, Connecticut has 
fulfilled the specific elements of that guidance as follows:
    A. Connecticut is implementing the EPA-approved PM10 SIP.
    B. New Haven has monitored no more than 1 exceedance during 1994, 
the year preceding the extension year.1

    \1\A review of the PM10 air quality data for New Haven shows air 
quality monitors for this area monitored 4 exceedances of the 24-
hour PM10 NAAQS during the 3-year period from 1992 to 1994. All 
exceedances occurred in 1993 at the Yankee Gas monitor site (AIRS 
Site ID 09-009-0021). The area did not have any exceedances of the 
PM10 NAAQS in 1994.
---------------------------------------------------------------------------

    C. 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.2

    \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 (submitted to EPA on March 22, 1994) as meeting RFP and the 
first quantitative milestone for New Haven. (See TSD dated March 27, 
1995.)
---------------------------------------------------------------------------

    Connecticut's extension request states that indeed the area 
recorded no exceedances of the PM10 NAAQS in 1994, and is complying 
with the applicable state implementation plan. For further details 
regarding Connecticut's extension request and how it meets EPA's 
requirements, the reader should refer to the TSD dated June 13, 1995.

Final Action

    EPA is approving an extension of the PM10 attainment date for New 
Haven, Connecticut to December 31, 1995.
    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, EPA is proposing to approve the SIP revision 
should adverse or critical comments be filed. This action will be 
effective November 13, 1995 unless adverse or critical comments are 
received by October 11, 1995.
    If the EPA receives such comments, this action will be withdrawn 
before the effective date by simultaneously publishing a subsequent 
notice 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 on November 13, 1995.
    Under Executive Order 12866, 58 FR 51735 (October 4, 1993) EPA is 
required to determine whether regulatory actions are significant and 
therefore should be subject to OMB review, economic analysis, and the 
requirements of the Executive Order. The Executive Order defines a 
``significant regulatory action'' as one that is likely to result in a 
rule that may meet at least one of the four criteria identified in 
section 3(f), including, under paragraph (1), that the rule may ``have 
an annual effect on the economy of $100 million or more or adversely 
affect, in a material way, the economy, a sector of the economy, 
productivity, competition, jobs, the environment, public health or 
safety, or State, local, or tribal governments or communities.''
    The Agency has determined that the attainment date extension 
proposed today would result in none of the effects identified in 
section 3(f). Attainment date extensions under Sec. 188(d) of the Act 
do not impose any new requirements on any sectors of the economy; nor 
do they result in a materially adverse impact on State, local, or 
tribal governments or communities.
    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.
    Under Secs. 202, 203, and 205 of the Unfunded Mandates Reform Act 
of 1995 (``Unfunded Mandates Act''), signed into law on March 22, 1995, 
EPA must assess whether various actions undertaken in association with 

[[Page 47099]]
proposed or final regulations that include a Federal mandate that may 
result in estimated costs of $100 million or more to the private 
sector, or to State, local, or tribal governments in the aggregate.
    EPA has determined, as discussed earlier, that the finding that is 
the subject of this final action of failure to attain and grant a 1-
year extension does not impose any federal intergovernment mandate, as 
defined in section 101 of the Unfunded Mandates Act. A finding that an 
area has failed to attain and should be granted a 1-year extension of 
the attainment date consists of factual determinations based upon air 
quality considerations and the area's compliance with certain prior 
requirements. Accordingly, no additional costs to State, local, or 
tribal governments, or to the private sector result from this action. 
This action also will not impose a 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.
    Extensions of attainment dates under Sec. 188(d) 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 federal-state relationship under the CAA, preparation of 
a regulatory flexibility analysis would constitute federal inquiry into 
the economic reasonableness of state action. The CAA forbids EPA to 
base its actions concerning SIPs on such grounds. Union Electric Co. v. 
USEPA, 427 US 246, 256-66 (S.Ct. 1976); 42 USC Sec. 7410 (a)(2).
    This action has been classified as a Table 3 action by the Regional 
Administrator under the procedures published in the Federal Register on 
January 19, 1989 (54 FR 2214-2225), as revised by an October 4, 1993, 
memorandum from Michael H. Shapiro, Acting Assistant Administrator for 
Air and Radiation. A future notice will inform the general public of 
these tables. The Office of Management and Budget (OMB) has exempted 
this action from review under Executive Order 12866.
    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.
    Under Sec. 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 November 13, 1995. 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 Sec. 307(b)(2).]
