1 An exceedance is defined as a daily value that is above the level of the 24-hour standard (150 μg/

m 3 ) after rounding to the nearest 10 μg/m 3 (i.e. values ending in 5 or greater are to be rounded up). Thus, a recorded value of 154 μg/m 3 would not be an exceedance since it would be rounded to 150 μ /

m 3 whereas a recorded value of 155 μg/m 3 would be an exceedance since it would be rounded to 160
μ /m 3 . See 40 CFR part 50, appendix K, section 1.0. NR 428.25(1)(b) to (d), NR 428.25(2), NR 428.25(3)(a), and NR 428.25(3)(c) as published in the Wisconsin Administrative Register, on July 30, 2007, No. 619, effective August 1, 2007.

A. PM 10 Standard

The NAAQS are levels for certain ambient air pollutants set by EPA to protect public health and welfare. PM 10 , or particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers, is among the ambient air pollutants for which EPA has established health-based standards. On July 1, 1987 (52 FR 24634), EPA promulgated two primary standards for PM 10 : A 24-hour standard of 150 micrograms per cubic meter ( μg/m 3 ) and an annual PM 10 standard of
50 μg/m 3 . EPA also promulgated secondary PM 10 standards that were identical to the primary standards.

Effective December 18, 2006, EPA revoked the annual PM 10 standard but retained the 24-hour PM 10 standard. 71 FR 61144 (October 17, 2006). The 24- hour PM 10 standard is attained when the expected number of days per calendar year with a 24-hour concentration above
154 μg/m 3 , as determined in accordance with 40 CFR part 50, appendix K, is equal to or less than one. 1 40 CFR 50.6 and 40 CFR part 50, appendix K.


### 64163 Federal Register / Vol. 75, No. 201 / Tuesday, October 19, 2010 / Rules and Regulations

2 EPA promulgated amendments to the ambient air monitoring regulations in 40 CFR parts 53 and 58 on October 17, 2006. See 71 FR 61236. The requirements for Special Purpose Monitors were revised and moved from 40 CFR 58.14 to 40 CFR
58.20. 3 To meet data completeness criteria, missing data in the first quarter of 1994 was substituted according to EPA guidance. See ‘‘ PM 10 SIP Development Guideline ’’ (EPA–450/2–86–001, June 1987), ‘‘ Guideline on Exceptions to Data Requirements for Determining Attainment of Particulate Matter Standards ’’ (EPA–450 4–87–005, April 1987), and the data completeness discussion in the Memorandum from Chris Hall entitled ‘‘ Eagle River PM 10 Attainment Determination, ’’ (October 5, 2010).

4 ‘‘ Guideline on the Identification and Handling of Ambient Air Quality Data Affected by Special Events or Special Conditions ’’ (EPA–454/D–94–001, September, 1994). B. The Eagle River PM 10 Nonattainment Area

On August 7, 1987 (52 FR 29383), EPA identified a number of areas across the country as PM 10 ‘‘ Group I ’’ areas of concern, that is, areas with a 95% or greater likelihood of violating the PM 10 NAAQS and requiring substantial planning efforts. The Eagle River PM 10 nonattainment area was identified as a Group I area of concern.

Areas meeting the requirements of section 107(d)(4)(B) were designated nonattainment for PM 10 by operation of law and classified ‘‘ moderate ’’ upon enactment of the 1990 Clean Air Act Amendments. See generally 42 U.S.C. 7407(d)(4)(B). These areas included all former Group I PM 10 planning areas identified in 52 FR 29383 (August 7, 1987), and further clarified in 55 FR 45799 (October 31, 1990), and any other areas violating the NAAQS for PM 10 prior to January 1, 1989. A Federal Register notice announcing the areas designated nonattainment for PM 10 upon enactment of the 1990 Clean Air Act Amendments, known as ‘‘ initial ’’ PM 10 nonattainment areas, was published on March 15, 1991 (56 FR 11101). The Eagle River PM 10 nonattainment area was one of these initial moderate PM 10 nonattainment

areas. C. Attainment Date for the Eagle River PM 10 Nonattainment Area

All initial moderate PM 10 nonattainment areas had the same applicable attainment date of December 31, 1994. States containing initial moderate PM 10 nonattainment areas were required to develop and submit to EPA by November 15, 1991, a state implementation plan (SIP) revision providing implementation of reasonably available control measures (RACM), including reasonably available control technology (RACT), and a demonstration of whether attainment of the PM 10 NAAQS by the December 31, 1994, attainment date was practicable. See section 189(a).

D. PM 10 Planning in the Eagle River PM 10 Nonattainment Area After the Eagle River PM 10 nonattainment area was designated nonattainment for PM 10 , the Alaska Department of Environmental Conservation (ADEC) began in the early 1990s to prepare the technical elements needed to bring the area into attainment and meet the planning requirements of title I of the CAA. Based on these technical products ADEC, developed and implemented control measures on PM 10 sources in the Eagle River PM 10 nonattainment area. The State submitted these control measures to EPA on October 15, 1991, as a moderate PM 10 nonattainment SIP revision under section 189(a) of the Act. The control strategy focused on implementing road surfacing and paving projects to reduce fugitive dust from paved and unpaved streets and windblown dust. EPA took final action to approve the State’s moderate PM 10 SIP on August 13, 1993. See 58 FR 43084.

II. Attainment Determination A. What are the requirements for attainment determinations?

Generally, EPA determines whether an area’s air quality is meeting the PM 10NAAQS based upon complete, qualityassured data gathered at established state and local air monitoring stations (SLAMS) and national air monitoring stations (NAMS) in the nonattainment areas and entered into the EPA Air Quality System (AQS). Data from air monitors operated by state/local/tribal agencies in compliance with EPA monitoring requirements must be submitted to AQS. EPA relies primarily on data in AQS when determining the attainment status of an area. See 40 CFR 50.6; 40 CFR part 50, appendix J; 40 CFR part 53; 40 CFR part 58, appendix A. EPA will also consider air quality data from other air monitoring stations in the nonattainment area provided that the stations meet the Federal monitoring requirements for SLAMS, including the quality assurance and quality control criteria in 40 CFR part 58, appendix A. 40 CFR 58.14 (2006) and 58.20 (2007); 2 71 FR 61236, 61242 (October 17, 2006). All valid data are reviewed to determine the area’s air quality status in accordance with 40 CFR part 50, appendix K.

Attainment of the 24-hour PM 10 standard is determined by calculating the expected number of exceedances of the standard in a year. The 24-hour standard is attained when the expected number of days per calendar year with a 24-hour concentration above 154 μg/

m 3 , as determined in accordance with 40 CFR part 50, appendix K, is less than or equal to one. Generally, three consecutive years of air quality data are required to show attainment of the 24- hour PM 10 standard. See 40 CFR part 50 and appendix K. B. What do the air quality data show as of the December 31, 1994 attainment date?

Because the Eagle River PM 10 nonattainment area has a December 31, 1994, attainment date, our determination of whether or not the area attained the standard is based on 1992, 1993 and 1994 complete quality-assured data for the area. During that period, the State of Alaska operated two PM 10 SLAMS monitoring sites within the Eagle River nonattainment area: the Parkgate site and the Baronoff site. Both monitoring sites met EPA SLAMS network design and siting requirements set forth at 40 CFR part 58, appendices D and E. The Parkgate site began operation in 1985 and continues to operate. The Baronoff site began operating in May of 1992 and ceased operation in 1996.
Parkgate Site

Our review of complete qualityassured air quality data from the Parkgate site for the period from January 1, 1992 through December 31, 1994, shows that one 24-hour PM 10 value, reported on September 16, 1992, exceeded the level of the 24-hour standard. 3 This 24-hour value was flagged by ADEC in AQS as a special event due to a volcanic eruption. Under EPA’s 1994 guidance, 4 data may be excluded from regulatory determinations related to exceedances or violations of the NAAQS if it is adequately demonstrated that a special event caused the exceedance or violation. EPA concurred on this exceedance as a special event in a letter to ADEC on May 24, 1995. Consequently, this value is excluded from expected exceedance calculations. Because there was no other recorded exceedance of the 24-hour PM 10 standard during calendar years 1992– 1994, the expected PM 10 exceedance rate for the 1992–1994 period at the Parkgate site is 0.0. Therefore, the Parkgate site has demonstrated attainment for the 24-hour PM 10


### 64164 Federal Register / Vol. 75, No. 201 / Tuesday, October 19, 2010 / Rules and Regulations

5 Because data for the 1st quarter 1992 was less than 50% complete, the substitution guidance used for the Parkgate site was not used for this site.

6 Based on the available data, the site does not show a violation of the 24-hour PM 10 NAAQS. See 40 CFR part 50, appendix K, section 2.3(c). 7 Note that ADEC has recently advised EPA of an exceedance in September 2010 that they also intend to flag as a high wind exceptional event. NAAQS as of the attainment date of December 31, 1994.

Additionally, we evaluated expected exceedances for the three-year period prior to and after the attainment date. Because other than the September 1992 special event, no other exceedance was recorded during calendar years 1991 through 1997, the Parkgate site has also demonstrated attainment of the 24-hour PM 10 NAAQS for calendar years 1991– 1993, 1993–1995, 1994–1996, and 1995–
1997. Baronoff Monitoring Site

EPA also reviewed the data from the Baronoff site, the other SLAMS site in the Eagle River PM 10 nonattainment area that was operating during the 1992– 1994 period. Because this monitor began operating on May 27, 1992, and did not operate for one full quarter during the 1992–1994 period, the data from this monitor cannot be used for making a determination of attainment for the 1992–1994 period. 5 Even so, we can evaluate whether the data from this monitor show that the Eagle River PM 10 nonattainment area failed to attain for the 1992–1994 period. Although the Baronoff site recorded three exceedances of the 24-hour PM 10 NAAQS in the 1992–1994 period (all in 1992), these values were flagged by ADEC as special events due to a volcanic eruption. EPA concurred on the flagged exceedances in a May 24, 1995, letter to ADEC and thus these values are excluded from the expected exceedance calculations. Outside of these flagged exceedances there has been no other exceedance of the 24-hour PM 10 standard at the Baronoff site from May 27, 1992 through December 31, 1994 (nor through October 1, 1996, when the monitor ceased operation). We therefore conclude that data from the Baronoff site does not show the Eagle River PM 10 nonattainment area failed to attain the PM 10 standard by the December 31, 1994, attainment date. 6 C. What does more recent air quality data show?

Although the attainment date for the Eagle River PM 10 nonattainment area is December 31, 1994, and the air quality data used to determine attainment by that date includes all data collected in calendar years 1992, 1993, and 1994, EPA has also reviewed the air quality data collected at the State monitoring sites from January 1992 through the most recent available data in AQS. The Parkgate site recorded one exceedance of the standard in each of the years 2007 and 2009. These exceedances were timely flagged by ADEC as exceptional events due to high winds and will be evaluated by EPA under the Exceptional Events Rule and addressed in a separate action. 7 Under the Exceptional Events Rule, EPA may exclude data from regulatory determinations related to exceedances or violations of the NAAQS if it is adequately demonstrated that an exceptional event caused the exceedance or violation. 40 CFR 50.1, 50.14. If in the future EPA determines, after notice-and-comment rulemaking, that the area is no longer attaining the PM 10 NAAQS, EPA will publish such determination in the Federal Register.

III. EPA’s Final Action

EPA is determining that the Eagle River area has attained the PM 10 standard based on the three years of complete, quality-assured data as of the attainment date of December 31, 1994. For the period from 1992–1994, the expected exceedance rate of 0.0 for the Parkgate site is equal to or less than the expected exceedance rate of 1.0 that is allowed under the PM 10 NAAQS. Because complete quality-assured data for this period show an expected exceedance rate equal to or below the PM 10 standard, EPA concludes that the area has met the standard. EPA therefore determines that the Eagle River nonattainment area has attained the 24- hour PM 10 NAAQS as of the December 31, 1994, attainment date. IV. Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA’s role is to approve state choices, provided that they meet the criteria of the Clean Air Act. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action:

• Is 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); • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq. );

• Is 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. );

• 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);

• Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);

• Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);

• Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);

• Is 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

• Does 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.

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a ‘‘ major rule ’’ as defined by 5 U.S.C. 804(2).


### 64165 Federal Register / Vol. 75, No. 201 / Tuesday, October 19, 2010 / Rules and Regulations

Under section 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 December 20, 2010. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action 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. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the proposed rules section of today’s Federal Register, rather than file an immediate petition for judicial review of this direct final rule, so that EPA can withdraw this direct final rule and address the comment in the proposed rulemaking. This action may not be challenged later in proceedings to enforce its requirements. See section 307(b)(2). List of Subjects in 40 CFR Part 81
