Approval and Promulgation of Air Quality Implementation Plans; Massachusetts; Determination of Attainment of the 1997 Ozone Standard for the Western Massachusetts Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA is proposing two separate and independent determinations regarding the Springfield (Western Massachusetts) moderate 1997 8-hour ozone nonattainment area. First, EPA is proposing to determine that the Western Massachusetts nonattainment area has attained the 1997 8-hour National Ambient Air Quality Standard (NAAQS) for ozone, 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 and 2008-2010 monitoring periods. Preliminary data for 2011 indicate the area continues to attain the standard. If this proposed determination is made final, under the provisions of EPA's ozone implementation rule, the requirements for this area to submit an attainment demonstration, a reasonable further progress plan, contingency measures, and other planning State Implementation Plans related to attainment of the 1997 8-hour ozone NAAQS shall be suspended for so long as the area continues to attain the 1997 ozone NAAQS. Second, based on complete, quality-assured and certified air monitoring data for 2007-2009, EPA is proposing to determine that the Western Massachusetts nonattainment area also attained the 1997 ozone NAAQS as of June 15, 2010, its applicable attainment date.

  7. What actions is EPA taking?

    EPA is proposing to determine that the Springfield (Western Massachusetts) moderate 8-hour ozone nonattainment area (hereafter ``the Western Massachusetts area'') has attained 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 and 2008-2010 monitoring periods. Preliminary data available for 2011 indicate the area continues to attain the standard. In addition, pursuant to section 181(b)(2)(A) of the Clean Air Act (CAA), and based upon complete, quality assured and certified air monitoring data for 2007-2009, EPA is proposing to determine that this area attained the 1997 ozone NAAQS by its applicable attainment date (June 15, 2010).

  8. What is the effect of these actions?

    If EPA's determination that the area is attaining the standard is made final, under the provisions of EPA's ozone implementation rule (see 40 CFR Section 51.918), the requirements for the Western Massachusetts moderate ozone nonattainment 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 would be suspended for so long as the area continues to attain the 1997 8-hour ozone NAAQS. 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.

    If this determination of attainment is finalized and EPA subsequently determines, after notice-and-comment rulemaking in the Federal Register, that the area has violated the 1997 8-hour ozone standard, the basis for the suspension of these requirements would no longer exist, and the area would thereafter have to address the pertinent CAA requirements. It should be noted, that Massachusetts submitted an attainment demonstration, reasonable further progress (RFP) plan and contingency measures for this area on January 31, 2008. EPA has not taken action on the attainment demonstration but has proposed approval of the RFP plan and contingency measures for the Western Massachusetts area. (See 75 FR 57221, September 20, 2010.)

    In addition, 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 the Western Massachusetts area 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.

  9. 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 Western Massachusetts area was designated as a moderate ozone nonattainment area. The Western Massachusetts nonattainment area consists of Berkshire, Franklin, Hampden and Hampshire counties. Recent air quality data indicate that the Western Massachusetts area is attaining the 1997 8-hour ozone standard.

  10. 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 Western Massachusetts, from 2007 through 2010.

    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 3-year average of the percent of days with valid ambient monitoring data is more 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 four Western Massachusetts area monitors for the years 2007-2009, and the ozone design values for these same monitors based on 2007-2009. Table 2 shows similar data for the 2008-2010 monitoring period.

    EPA's review of these data indicates that the Western Massachusetts area attained the 1997 8-hour ozone NAAQS and met its applicable attainment deadline, based on 2007-2009 data. Our review also shows that the area continues to attain the standard, based on complete, quality-assured and certified data for the 2008-2010 monitoring period. Preliminary ozone data for the 2011 ozone monitoring season also indicate attainment.

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

    \1\ The data capture percentage for this ozone monitor was below EPA data capture requirements for the 1997 8-hour ozone NAAQS, for both the 2007-2009 and 2008-2010 monitoring periods. The Massachusetts Department of Environmental Protection performed a missing data analysis for this site in accordance with the regulatory requirements of 40 CFR part 50, Appendix I. The Massachusetts missing data analysis used a combination of meteorology and air quality data for ozone monitors near the Adams site for the missing days to decisively conclude that on the days with missing ozone data, the ozone levels, if captured, would have been below the 1997 8-hour ozone NAAQS. Thus, by rule, these days can be counted for the purpose of meeting the data completeness requirement. The missing data analysis for this site was approved by EPA on December 15, 2011. The approval letter is in the Docket for this action.

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

    EPA is soliciting public comments 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.

  11. Proposed Actions

    EPA is proposing two separate and independent determinations. First, EPA is proposing to determine that the Western Massachusetts 1997 8-hour ozone moderate nonattainment area has attained the 1997 8-

    hour ozone standard, based on complete, quality-assured data for the 2007-2009 and 2008-2010 monitoring periods. Preliminary data available for 2011 indicate the area continues to attain the standard. As provided in 40 CFR 51.918, if EPA finalizes this determination, it would suspend the requirements for Massachusetts to submit planning SIPs related to attainment of the 1997 8-hour ozone NAAQS for this area, for so long as the area continues to attain the standard.\2\ 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 Section 51.902(a)), based upon complete, quality-assured and certified data for 2007-2009, EPA is proposing to determine that this area has attained the 1997 ozone NAAQS by its applicable attainment date of June 15, 2010.

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

    \2\ Massachusetts submitted an attainment demonstration and contingency measures for this area on Jan. 31, 2008. EPA has not taken action on the attainment demonstration, but has proposed approval of the reasonable further progress plan and contingency measures. (See 75 FR 57221, Sept. 10, 2010.)

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

  12. Statutory and Executive Order Reviews

    These actions propose to make determinations of attainment based on air quality, and would, if finalized, result in the 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 actions'' 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.
