Proposed rule.

SUMMARY:

The EPA is proposing to make four separate and independent determinations for two areas in New Hampshire. First, with respect to the Portsmouth-Dover-Rochester, (Portsmouth) serious one-hour ozone nonattainment area, EPA is proposing to determine that the area attained the one-hour National Ambient Air Quality Standard (NAAQS) for ozone, by the applicable deadline of November 15, 1999. Second, EPA is proposing to determine that the Portsmouth area attained the one-hour ozone standard in 1999, and continues to attain the standard. Third, EPA is proposing to determine that the Manchester marginal one-hour ozone nonattainment area attained the one-hour NAAQS, by the applicable deadline of November 15, 1993. Fourth, EPA is proposing to determine, that the Manchester area has attained the one-hour ozone standard since 1993, and continues to attain the standard.

VI. Statutory and Executive Order Reviews

I. What is EPA proposing?

EPA is proposing to determine that the Portsmouth, NH serious one-hour ozone nonattainment area attained the one-hour ozone NAAQS by the deadline of November 15, 1999. This proposed determination is based upon complete, quality-assured and certified air quality monitoring data for the 1997-1999 ozone seasons showing that the area had an expected ozone exceedance rate below the level of the now revoked one-hour ozone NAAQS during that period and therefore attained the standard by its applicable deadline. EPA is also proposing to determine that the Portsmouth, NH area is currently attaining the standard based on complete, certified and quality-assured ozone monitoring data since 1999 and continues to attain the standard based on the most recent three years of complete, quality-assured and certified ozone monitoring data (2009-2011). If EPA finalizes its determination, that the area is currently attaining the one-hour standard, in accordance with EPA's interpretation under the Clean Data Policy, it will relieve the area of the obligation to submit one-hour ozone contingency measures for failure to attain.

In addition, EPA is proposing to determine that the Manchester, NH marginal one-hour ozone nonattainment area attained the one-hour ozone NAAQS by the applicable deadline of November 15, 1993. This proposed determination is based upon complete, certified, quality-assured ambient air quality monitoring data for the 1991-1993 ozone seasons showing that the area had an expected ozone exceedance rate below the level of the now revoked one-hour ozone NAAQS during that period, and that the area attained the standard by its applicable deadline. EPA is also proposing to determine that the Manchester, NH area has attained the one-hour ozone standard since 1993, and continues to attain the standard based on the most recent three years of complete, quality-assured and certified ozone monitoring data (2009-2011).

II. What is the background for these proposed actions?

EPA designated the Portsmouth, NH serious one-hour ozone nonattainment area as nonattainment for the one-hour ozone standard following the enactment of the Clean Air Act (CAA) Amendments of 1990. Most areas of the country that EPA designated nonattainment for the one-hour ozone NAAQS were classified by operation of law as marginal, moderate, serious, severe, or extreme, depending on the severity of the area's air quality problem. (See CAA sections 107(d)(1)(C) and 181(a).) The Portsmouth, NH one-hour ozone nonattainment area was classified as serious. The one-hour ozone attainment deadline for the area was November 15, 1999. The Portsmouth, NH area has both an approved 15 Percent Reasonable Further Progress (RFP) plan and a Post-96 RFP plan. (See 63 FR 67405, December 7, 1998; and 67 FR 18493, April 16, 2002.) The area does not have an approved one-hour attainment demonstration, or one-hour contingency measures, but if EPA finalizes its proposed one-hour determinations, there would be no requirement for the Portsmouth, NH area to submit or implement one-hour ozone contingency measures for failure to attain the standard or for the Portsmouth, NH area to submit or implement a one-hour attainment demonstration.

In addition, EPA designated the Manchester, NH one-hour ozone nonattainment area as marginal for the one-hour ozone standard. The one-hour ozone attainment deadline for this area was November 15, 1993. Marginal areas had very few CAA requirements. For example one-hour ozone marginal areas did not have to prepare or submit attainment demonstrations, RFP or contingency measures. Table 1 lists the cities and towns in the Portsmouth and Manchester, NH one-hour ozone nonattainment areas. (See also 40 CFR 81.330.)

On July 18, 1997 (62 FR 38856), EPA promulgated for the first time a new standard for ozone based on an 8-hour average concentration (the “1997 8-hour ozone NAAQS”). EPA designated and classified most areas of the country under the eight-hour ozone NAAQS in an April 30, 2004 final rule (69 FR 23858). EPA designated Southern New Hampshire as nonattainment for the 1997 8-hour ozone NAAQS. This area is known as the Boston-Manchester-Portsmouth (SE), NH area. At the time of eight-hour designations, the Boston-Manchester-Portsmouth (SE), NH area did not meet the one-hour ozone standard. The Boston-Manchester-Portsmouth (SE), NH area is composed of portions of three separate one-hour ozone nonattainment areas: (1) The Portsmouth, NH serious one-hour ozone nonattainment area; (2) the Boston-Lawrence-Worcester, MA-NH one-hour ozone nonattainment area; and (3) the Manchester, NH marginal one-hour ozone nonattainment area. This proposed action concerns the Portsmouth, NH serious one-hour ozone nonattainment area, and the Manchester, NH marginal one-hour ozone nonattainment area. The Boston-Lawrence-Worcester, MA-NH one-hour ozone nonattainment area, was the subject of a previous Federal Register notice that determined the Boston-Lawrence-Worcester, MA-NH one-hour ozone nonattainment area attained the one-hour NAAQS by its attainment date (see 77 FR 31496, May 29, 2012).

On April 30, 2004, EPA issued a final rule (69 FR 23951) entitled “Final Rule To Implement the 8-Hour Ozone National Ambient Air Quality Standard—Phase 1,” referred to as the Phase 1 Rule. Among other matters, this rule revoked the one-hour ozone NAAQS in most areas of the country, effective June 15, 2005. (See 40 CFR 50.9(b); 69 FR at 23996; and 70 FR 44470, August 3, 2005.) The Phase 1 Rule also set forth how anti-backsliding principles will ensure continued progress toward attainment of the eight-hour ozone NAAQS by identifying which one-hour requirements remain applicable in an area after revocation of the one-hour ozone NAAQS. Although EPA revoked the one-hour ozone standard (effective June 15, 2005), eight-hour ozone nonattainment areas remain subject to certain one-hour anti-backsliding requirements based on their one-hour ozone classification.[1] The United States Court of Appeals for the District of Columbia Circuit subsequently determined that EPA should have retained certain additional measures as one-hour ozone anti-backsliding requirements. These include one-hour ozone contingency measures under section 172(c)(9), which are to be implemented in the event an area fails to attain by its one-hour ozone attainment date. South Coast Air Quality Management District v. EPA, 472 F.3d 882 (D.C. Cir. 2006) rehearing denied 489 F.3d 1245. EPA has since added one-hour ozone contingency measures as an applicable requirement in 40 CFR 51.900(o). (See 77 FR 28424, May 14, 2012).

EPA is proposing two separate and independent determinations for the Portsmouth, NH serious one-hour ozone nonattainment area. First, EPA is proposing to determine that the area attained the one-hour ozone standard by its attainment deadline, the end of the 1999 ozone season, and second, that the area continues to attain that NAAQS. If EPA finalizes its proposed determinations, there would be no requirement for the Portsmouth, NH area to submit or implement one-hour ozone contingency measures for failure to attain that standard.

In addition, EPA is proposing to determine that the Manchester, NH marginal one-hour ozone nonattainment area attained the one-hour ozone standard by its attainment date, the end of the 1993 ozone season, and that the area continues to attain that NAAQS. Since the Manchester, NH area is a marginal nonattainment area for the one-hour ozone standard, the area has no CAA-required contingency measures for failure to attain the one-hour NAAQS.

III. What is EPA's analysis of data for purposes of determining attainment of the one-hour ozone standard?

A. How does EPA compute whether an area has attained the one-hour ozone standard?

Although the one-hour ozone NAAQS as promulgated in 40 CFR 50.9 includes no discussion of specific data handling conventions, EPA's publicly articulated position and the approach long since universally adopted by the air quality management community is that the interpretation of the one-hour ozone standard requires rounding ambient air quality data consistent with the stated level of the standard, which is 0.12 parts per million (ppm). 40 CFR 50.9(a) states that: “The level of the national one-hour primary and secondary ambient air quality standards for ozone * * * is 0.12 parts per million. * * * The standard is attained when the expected number of days per calendar year with maximum hourly average concentrations of 0.12 parts per million * * * is equal to or less than 1, as determined by appendix H to this part.” Thus, compliance with the NAAQS is based on comparison of air quality concentrations with the standard and on the number of days that standard has been exceeded, adjusted for the number of missing days.

For comparison with the NAAQS, EPA has communicated the data handling conventions for the one-hour ozone NAAQS in guidance documents. As early as 1979, EPA issued guidance stating that the level of our NAAQS dictates the number of significant figures to be used in determining whether the standard was exceeded. The stated level of the standard is taken as defining the number of significant figures to be used in comparisons with the standard. For example, a standard level of 0.12 ppm means that measurements are to be rounded to two decimal places (0.005 rounds up), and, therefore, 0.125 ppm is the smallest concentration value in excess of the level of the standard. (See, “Guideline for the Interpretation of Ozone Air Quality Standards,” EPA-450/4-79-003, OAQPS No. 1.2-108, January 1979.) EPA has consistently applied the rounding convention in this 1979 guideline. See, 68 FR 19111, April 17, 2003; 68 FR 62043, October 31, 2003; and 69 FR 21719, April 22, 2004. Then, EPA determines attainment status under the one-hour ozone NAAQS on the basis of the annual average number of expected exceedances of the NAAQS over a three-year period. (See, 60 FR 3349, January 17, 1995 and “General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990,” at 57 FR 13506, April 16, 1992 (“General Preamble”).) EPA's determination is based upon data that have been collected and quality-assured in accordance with 40 CFR part 58, and recorded in EPA's Air Quality System (AQS) database. To account for missing data, the procedures found in appendix H to 40 CFR part 50 are used to adjust the actual number of monitored exceedances of the standard to yield the annual number of expected exceedances (“expected exceedance days”) at an air quality monitoring site. We determine if an area meets the one-hour ozone NAAQS by calculating, at each monitor, the average expected number of days over the standard per year (i.e., “average number of expected exceedance days”) during the applicable 3-year period. See, the General Preamble, 57 FR 13498, April 16, 1992. The term “exceedance” is used throughout this document to describe a daily maximum ozone measurement that is equal to or exceeds 0.125 ppm which is the level of the standard after rounding. An area violates the ozone standard if, over a consecutive 3-year period, more than 3 days of expected exceedances occur at the same monitor. For more information please refer to 40 CFR 50.9 “National one-hour primary and secondary ambient air quality standards for ozone” and “Interpretation of the one-hour Primary and Secondary National Ambient Air Quality Standards for Ozone” (40 CFR part 50, appendix H).

B. EPA's Analysis of the One-Hour Ozone Data for the Portsmouth, NH Serious One-Hour Ozone Nonattainment Area

Table 2 shows a summary of one-hour ozone data for all the ozone monitors in the Portsmouth, NH serious one-hour ozone nonattainment area for the period 1997-2011. In short, if the three-year average expected exceedance rate, shown in the far right column, is less than or equal to 1.0, the site meets the one-hour ozone NAAQS. If all sites in the area are shown to meet the one-hour ozone NAAQS, it can be determined that the area has attained the one-hour ozone NAAQS.

As shown in Table 2, the Portsmouth, NH serious one-hour ozone nonattainment area attained the one-hour ozone NAAQS at the end of the 1999 ozone season, since the three ozone monitors (Rye-Harbor State Park, Portsmouth-Vaughan Street, and Rochester-Rochester Hill Road) had expected exceedance rates below 1.0. Thus EPA is proposing to determine that, based on the 1997-1999 complete, quality-assured and certified ozone data in the Air Quality System (AQS) database, the Portsmouth, NH serious one-hour ozone nonattainment area met the one-hour ozone NAAQS, by the attainment deadline of November 15, 1999. EPA is also proposing to determine that the area has remained in attainment of the one-hour NAAQS ever since.

C. EPA's Analysis of the One-Hour Ozone Data for the Manchester, NH Marginal One-Hour Ozone Nonattainment Area

Table 3 shows the results of one-hour ozone data for all the ozone monitors in the Manchester, NH marginal one-hour ozone nonattainment area for the period 1991-2011. In short, if the three-year average expected exceedance rate, shown in the far right column, is less than or equal to 1.0, the site meets the one-hour ozone NAAQS. If all sites in the area are shown to meet the one-hour ozone NAAQS, it can be determined that the area has attained the one-hour ozone NAAQS.

* Three year average expected exceedance rate cannot be calculated because the site has less than 3 years of data. For this area the two sites with an asterisk both have no exceedances for the time period in question.

As shown in Table 3, the Manchester, NH marginal one-hour ozone nonattainment area attained the one-hour ozone NAAQS at the end of the 1993 ozone season, since the one monitor (Manchester-Hartnett Park) with three years of data had an expected exceedance rate below 1.0. The other site (Concord-Storrs Street) began in 1992 and had no exceedance in either 1992 or 1993. Thus, EPA is proposing to determine that, based on the 1991-1993 complete, quality-assured and certified ozone data in the AQS database, the Manchester, NH marginal one-hour ozone nonattainment area met the one-hour ozone NAAQS, by its attainment deadline of November 15, 1993. Based on data from 1993-2011, EPA proposes to determine that the area has continued in attainment of the one-hour NAAQS ever since.

IV. What is the effect of the proposed determinations?

If EPA finalizes its proposed determination that the Portsmouth and Manchester, NH areas attained the one-hour ozone standard by their respective deadlines, there are no consequences for failure to attain that standard. For the Portsmouth, NH area, it would discharge any obligation with respect to contingency measures triggered by a failure to attain by the one-hour ozone attainment deadline. In addition, if EPA finalizes its determination that the Portsmouth, NH one-hour ozone area continues to attain the standard, under EPA's “Clean Data Policy” interpretation, which was first articulated for the one-hour standard and then codified for the eight-hour ozone standard (40 CFR 51.918), that determination suspends the Portsmouth, NH area's obligation to submit attainment-related requirements for the one-hour ozone standard, including contingency measures. See, for example, determination of one-hour ozone attainment for Baton Rouge, (75 FR 6570, February 10, 2010).

V. Proposed Determinations

For the reasons set forth in this notice, EPA is proposing four separate and independent determinations. First, EPA is proposing to determine that the Portsmouth, NH serious one-hour ozone nonattainment area met the applicable deadline of November 15, 1999, for attaining the one-hour NAAQS for ozone, based on 1997-1999 complete, certified and quality-assured ozone monitoring data. If EPA finalizes this determination, it would discharge any obligation with respect to contingency measures triggered by a failure to attain by the one-hour ozone attainment deadline. Second, EPA is proposing to determine that the Portsmouth, NH area is currently attaining the standard based on complete, certified and quality-assured ozone monitoring data since 1999 and continues to attain the standard based on the most recent three years of complete, quality assured ozone monitoring data. A final determination, by EPA, that the area is currently attaining the one-hour standard would relieve the area of its obligation to submit one-hour ozone contingency measures. Third, EPA is proposing to determine that the Manchester, NH marginal nonattainment area met the applicable deadline of November 15, 1993, for attaining the one-hour NAAQS for ozone. This proposed determination is based upon complete, certified, quality-assured ambient air quality monitoring data for the 1991-1993 monitoring period showing that the area had an expected ozone exceedance rate below the level of the now revoked one-hour ozone NAAQS during that period and therefore attained the standard by its applicable deadline. Fourth and last with respect to the Manchester, NH area, EPA is proposing to determine, that the area has attained the one-hour ozone standard since 1993, and continues to attain the standard based on the most recent three years of complete, quality-assured and certified ozone monitoring data.

EPA is soliciting public comments on the issues discussed in this notice or on other relevant matters. EPA will consider these comments before 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.

VI. Statutory and Executive Order Reviews

This action proposes to make determinations of attainment based on monitored air quality data, and/or does not impose additional requirements beyond those imposed by state law. For that reason, these proposed actions:

  • Are not “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 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, these actions do 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.
