 Environmental Protection Agency 40 CFR Part 52
[EPA-R01-OAR-2008-0069; A-1-FRL-8526-7]
 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Proposed rule.
 SUMMARY: The EPA is proposing to determine that the Boston-Manchester-Portsmouth (SE), New Hampshire moderate 8-hour ozone nonattainment area has attained the 8-hour National Ambient Air Quality Standard (NAAQS) for ozone. This determination is based upon certified ambient air monitoring data that show the area has monitored attainment of the 8-hour ozone NAAQS since the 2002-2004 monitoring period, and continues to monitor attainment of the NAAQS based on 2004-2006 data. In addition, quality controlled and quality assured ozone data for 2007 that are available in the EPA Air Quality System database, but not yet certified, show this area continues to attain the 8-hour ozone NAAQS. If this proposed determination is made final, 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 8-hour ozone NAAQS shall be suspended for so long as the area continues to attain the ozone NAAQS.

SUPPLEMENTARY INFORMATION: Throughout this document whenever “we,” “us,” or “our” is used, we mean EPA. Organization of this document. The following outline is provided to aid in locating information in this preamble. I. What Action Is EPA Taking? II. What Is the Effect of This Action? III. What Is the Background for This Action? IV. What Is EPA's Analysis of the Relevant Air Quality Data? V. Proposed Action VI. Statutory and Executive Order Reviews I. What Action Is EPA Taking? EPA is proposing to determine that the Boston-Manchester-Portsmouth (SE), New Hampshire moderate 8-hour ozone nonattainment area has attained the 8-hour National Ambient Air Quality Standard (NAAQS) for ozone. This determination is based upon certified ambient air monitoring data that show the area has monitored attainment of the ozone NAAQS since the 2002-2004 monitoring period, and monitoring data that continue to show attainment of the NAAQS based on 2004-2006 data. In addition, quality controlled and quality assured ozone data for 2007 that are available in the EPA Air Quality System (AQS) database, but not yet certified, show this area continues to attain the ozone NAAQS. II. What Is the Effect of This Action? If this determination is made final, under the provisions of EPA's ozone implementation rule (see 40 CFR Section 51.918), the requirements for the Boston-Manchester-Portsmouth (SE), New Hampshire 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 8-hour ozone NAAQS would be suspended for so long as the area continues to attain the ozone NAAQS. This proposed action, if finalized, would not constitute a redesignation to 
                    ( print page 7235)
                    attainment under 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 8-hour ozone NAAQS until such time as EPA determines that it meets the CAA requirements for redesignation to attainment. If this rulemaking is finalized and EPA subsequently determines, after notice-and-comment rulemaking in the 
                    **Federal Register**
                    , that the area has violated the 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 requirements. III. What Is the Background for This Action? On April 30, 2004 (69 FR 23857), EPA designated as nonattainment any area that was violating the 8-hour ozone NAAQS based on the three most recent years (2001-2003) of air quality data. Portions of Hillsborough, Merrimack, and Rockingham, and Strafford Counties in New Hampshire were designated as a moderate ozone nonattainment area (specifically, the Boston-Manchester-Portsmouth (SE), New Hampshire area). The rest of New Hampshire was designated as attainment of the 8-hour ozone NAAQS. (See 40 CFR 81.330.) More recent air quality data, however, indicate that the Boston-Manchester-Portsmouth (SE), New Hampshire area is now attaining the 8-hour ozone standard. 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 EPA Air Quality System (AQS) database, for the Boston-Manchester-Portsmouth (SE), New Hampshire ozone nonattainment area, from 2002 through the present time. On the basis of that review, EPA has concluded that this area attained the 8-hour ozone standard at the end of the 2004 ozone season, based on certified 2002-2004 ozone data, and continued to attain the standard through and inclusive of the 2004-2006 ozone seasons. In addition, quality controlled and quality assured ozone data for 2007, that are available in AQS, but not yet certified, show this area continues to attain the 8-hour ozone NAAQS. Under EPA regulations at 40 CFR Part 50, the 8-hour ozone standard is attained 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 (84 parts per billion (ppb)) at each monitor within the area, then the area is meeting the NAAQS. (See 69 FR 23857 (April 30, 2004) for further information.) 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 2004-2007. Table 2 shows the ozone design values for these same monitors based on the following 3-year periods: 2002-2004; 2003-2005; 2004-2006; and 2005-2007.

 EPA's review of these data indicate that the Boston-Manchester-Portsmouth (SE), New Hampshire ozone nonattainment area has met and continues to meet the 8-hour ozone NAAQS. EPA is soliciting public comments on the issues discussed in this notice or on other relevant matters. These comments will be considered before taking 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 Action EPA is proposing to determine that the Boston-Manchester-Portsmouth (SE), New Hampshire 8-hour ozone nonattainment area has attained the 8-hour ozone standard and continues to attain the standard based on data through the 2007 ozone season. As provided in 40 CFR Section 51.918, if EPA finalizes this determination, it would suspend the requirements for New Hampshire to submit an attainment demonstration, a reasonable further progress plan, and contingency measures under section 172(c)(9), and any other planning SIP related to attainment of the 8-hour ozone NAAQS for this area, for so long as the area continues to attain the standard. VI. Statutory and Executive Order Reviews Under Executive Order 12866 (58 FR 51735, October 4, 1993), this proposed action is not a “significant regulatory 
                    ( print page 7236)
                    action” and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001). This action proposes to make a determination based on air quality data, and would, if finalized, result in the suspension of certain Federal requirements. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601, 
                    *et seq.*). Because this rule proposes to make a determination based on air quality data, and would, if finalized, result in the suspension of certain Federal requirements, it does 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). This proposed rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). This proposed action also does not have Federalism implications because it does not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999), because it merely proposes to make a determination based on air quality data and would, if finalized, result in the suspension of certain Federal requirements, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This proposed rule also is not subject to Executive Order 13045 “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), because it proposes to determine that air quality in the affected area is meeting Federal standards. The requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply because it would be inconsistent with applicable law for EPA, when determining the attainment status of an area, to use voluntary consensus standards in place of promulgated air quality standards and monitoring procedures that otherwise satisfy the provisions of the Clean Air Act. This proposed rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501, 
                    *et seq.*) Under Executive Order 12898, EPA finds that this rule involves a proposed determination of attainment based on air quality data and will not have disproportionately high and adverse human health or environmental effects on any communities in the area, including minority and low-income communities.
