Approval and Promulgation of Air Quality Implementation Plans; 
New Hampshire; Determination of Attainment of the 1997 Ozone Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA is proposing to determine that the Boston-Manchester-
Portsmouth (SE), New Hampshire moderate 1997 8-hour ozone nonattainment 
area continues to attain the 1997 8-hour National Ambient Air Quality 
Standard (NAAQS) for ozone. This determination is based upon complete, 
quality-assured, certified ambient air monitoring data that show the 
area has monitored attainment of the 1997 8-hour ozone NAAQS for the 
2007-2009 monitoring period. Preliminary data available through June 
15, 2010 also are consistent with continued attainment. In addition, in 
accordance with the Clean Air Act, EPA is proposing to determine that 
this area has attained the 1997 ozone NAAQS as of June 15, 2010, its 
applicable attainment date.

I. What actions is EPA taking?

    EPA is proposing to determine that the Boston-Manchester-Portsmouth 
(SE), New Hampshire moderate 8-hour ozone nonattainment area continues 
to attain the 1997 8-hour NAAQS for ozone. This determination is based 
upon complete, quality-assured and certified ambient air monitoring 
data that show the area has monitored attainment of the 1997 ozone 
NAAQS for the 2007-2009 monitoring period. Data available through June 
15, 2010, in the EPA Air Quality System (AQS) are also consistent with 
continued attainment. In addition, under section 181(b)(2)(A) of the 
Clean Air Act (CAA), EPA is proposing to determine that this area has 
attained the 1997 ozone NAAQS by its applicable attainment date (June 
15, 2010).

II. What is the effect of these actions?

    Under section 181(b)(2)(A) of the CAA and the provisions of EPA's 
ozone implementation rule (see 40 CFR Section 51.902(a)), EPA is 
proposing to determine that this area has attained the 1997 ozone NAAQS 
by its applicable attainment date of June 15, 2010. The effect of a 
final determination of attainment by the area's attainment date would 
be to discharge EPA's obligation under section 181(b)(2)(A), and to 
establish that, in accordance with that section, the area would not be 
reclassified for failure to attain by its applicable attainment date. 
This proposed action, if finalized, would not constitute a 
redesignation to attainment under the Clean Air Act (CAA) section 
107(d)(3), because we would not yet have an approved maintenance plan 
for the area as required under section 175A of the CAA, nor a 
determination that the area has met the other requirements for 
redesignation. The classification and designation status of the area 
would remain moderate nonattainment for the 1997 8-hour ozone NAAQS 
until such time as EPA determines that the area meets the CAA 
requirements for redesignation to attainment.
    The further effect of this proposed action is to reaffirm EPA's 
prior determination of attainment for this area (See 73 FR 14387 (March 
18, 2004)), and thus, pursuant to 40 CFR. 51.918, to continue the 
suspension of New Hampshire's obligation to make certain SIP 
submissions for this area.

III. What is the background for these actions?

    On April 30, 2004 (69 FR 23857), EPA designated as nonattainment 
any area that was violating the 1997 8-hour ozone NAAQS based on the 
three most recent years (2001-2003) of air quality data. The Boston-
Manchester-Portsmouth (SE), New Hampshire area was designated as a 
moderate ozone nonattainment area. Subsequently, on March 18, 2008, EPA 
published in the Federal Register a determination that the area was 
attaining the 1997 8-hour ozone standard, based on complete, quality-
assured and certified data for 2004-2006. (See 73 FR 14387). That 
action suspended the obligation for the area to submit an attainment 
demonstration, a reasonable further progress plan, section 172(c)(9) 
contingency measures, and any other planning State Implementation Plans 
(SIPs) related to attainment of the 1997 8-hour ozone NAAQS for so long 
as the area continues to attain the 1997 ozone NAAQS. 40 CFR 51.918. 
Complete, certified ozone air quality data for 2007 through 2009, as 
well as complete, quality-assured, but not yet certified, ozone data 
available in AQS, through June 15, 2010, show that the Boston-
Manchester-Portsmouth (SE), New Hampshire area continues to meet the 
1997 8-hour ozone standard. Additional, preliminary ozone data 
available through September 30, 2010, continues to show this area meets 
the ozone NAAQS.

IV. What is EPA's analysis of the relevant air quality data?

    The EPA has reviewed the ambient air monitoring data for ozone, 
consistent with the requirements contained in 40 CFR part 50 and 
recorded in the Air Quality Data System (AQS) database, for Boston-
Manchester-Portsmouth (SE), New Hampshire area, from 2007 through 2009. 
On the basis of its review, EPA proposes to conclude that the area 
attained the 1997 8-hour ozone standard at the end of the 2009 ozone 
season, based on 3 years of complete, quality-assured and State-
certified 2007-2009 ozone data. Preliminary data available in the EPA 
Air Quality System, through June 15, 2010 are also consistent with 
continued attainment.
    Under EPA regulations at 40 CFR part 50, the 1997 8-hour ozone 
standard is attained at a site when the 3-year average of the annual 
fourth-highest daily maximum 8-hour average ozone concentrations at an 
ozone monitor is less than or equal to 0.08 parts per million (ppm) 
(i.e., 0.084 ppm, based on the rounding convention in 40 CFR part 50, 
appendix I). This 3-year average is referred to as the design value. 
When the design value is less than or equal to 0.084 ppm at each 
monitoring site within the area, then the area is meeting the NAAQS. 
Also, the data completeness requirement is met when the average percent 
of days with valid ambient monitoring data is greater than 90%, and no 
single year has less than 75% data completeness as determined in 
Appendix I of 40 CFR part 50.
    Table 1 shows the fourth-highest daily maximum 8-hour average ozone 
concentrations for the Boston-Manchester-Portsmouth (SE), New Hampshire 
nonattainment area monitors for the years 2007-2009, and the ozone 
design values for these same monitors based on 2007-2009.

    EPA's review of these data indicates that the Boston-Manchester-
Portsmouth (SE), New Hampshire ozone nonattainment area has met the 
1997 8-hour ozone NAAQS, based on 2007-2009 data. EPA believes these 
data, coupled with preliminary data available through June 15, 2010, 
indicate that the Boston-Manchester-Portsmouth (SE), New Hampshire area 
has also attained the standard as of its applicable attainment date of 
June 15, 2010. Thus, in accordance with CAA section 181(b)(2), EPA is 
also proposing to determine that the Boston-Manchester-Portsmouth (SE), 
New Hampshire area has attained the standard by its applicable 
attainment date.
    EPA is soliciting public comment on the issues discussed in this 
notice or on other relevant matters pertaining to this rulemaking 
action. These comments will be considered before EPA takes final 
action. Interested parties may participate in the Federal rulemaking 
procedure by submitting written comments to the EPA New England 
Regional Office listed in the ADDRESSES section of this Federal 
Register.

V. Proposed Actions

    EPA is proposing to determine that the Boston-Manchester-Portsmouth 
(SE), New Hampshire 1997 8-hour ozone moderate nonattainment area 
continues to attain the 1997 8-hour ozone standard, based on complete, 
quality-assured data from 2007 through 2009. Data for 2010 that are 
available in AQS through June 30, 2010 are consistent with continued 
attainment. As provided in 40 CFR Section 51.918, if EPA finalizes this 
determination, the requirements for New Hampshire to submit planning 
SIPs related to attainment of the 1997 8-hour ozone NAAQS for this area 
remain suspended, for so long as the area continues to attain the 
standard. In addition, under section 181(b)(2)(A) of the Clean Air Act 
and the provisions of EPA's ozone implementation rule (see 40 CFR 
51.902(a)), EPA is proposing to determine that this area has attained 
the 1997 ozone NAAQS by its applicable attainment date of June 15, 
2010.

VI. Statutory and Executive Order Reviews

    These actions propose to make determinations of attainment based on 
air quality, and would, if finalized, result in the continued 
suspension of certain Federal requirements, and would not impose 
additional requirements beyond those imposed by State law. For that 
reason, these proposed actions:
     Are not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     Do not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Are certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Do not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Do not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Are not economically significant regulatory actions based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Are not significant regulatory actions subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Are not subject to the requirements of Section 12(d) of 
the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 
272 note) because application of those requirements would be 
inconsistent with the Clean Air Act; and
     Do not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule does not have Tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the State, and EPA notes that it will not impose substantial direct 
costs on Tribal governments or preempt Tribal law.
