### 5281 Federal Register / Vol. 76, No. 20 / Monday, January 31, 2011 / Rules and Regulations

1 Because the annual PM 10 standard was revoked effective December 18, 2006, see 71 FR 61144 (October 17, 2006), this document discusses only attainment of the 24-hour PM 10 standard. Columbia Falls and Libby PM 10 nonattainment areas were in attainment of the revoked annual PM 10 standard.

2 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 μg/

m 3 whereas a recorded value of 155 μg/m 3 would be an exceedance since it would be rounded to 160
μg/m 3 . See 40 CFR part 50, appendix K, section 1.0. 3 The EPA used a three-step process to categorize areas into Groups I, II, and III. First, where only ambient TSP data or limited amounts of PM 10 data were available, EPA in cooperation with State agencies used those data and the probability guideline to classify areas preliminarily as Group I, II, or III. The EPA presumed that, at a minimum, the (1) areas with a probability of not attaining the PM 10 standard of at least 95 percent fit into Group I; (2) areas with a probability of between 20 and 95 percent fit into Group II; and (3) areas with a probability of less than 20 percent fit into Group III. 52 FR 29383, 29384 (August 7, 1987).

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. 1 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. 2 40 CFR 50.6 and 40 CFR part 50, appendix K.

The EPA also promulgated policies and regulations by which it will implement the PM 10 NAAQS (52 FR 24672). In accordance with these policies, EPA has categorized areas of the Nation into three groups based on the likelihood that the existing SIP must be revised to protect the PM 10 NAAQS. Areas with a strong likelihood of violating the PM 10 NAAQS and requiring substantial SIP revisions were placed in Group I; areas where attainment of the PM 10 NAAQS is uncertain and the SIP may require only slight adjustment were placed in Group II; and areas with a strong likelihood of attaining the PM 10 NAAQS, and therefore probably having an adequate control strategy, were placed in Group III. 3 By this notice, EPA is identifying the Group I and Group II areas in Montana that reached attainment.

B. Columbia Falls PM 10 Nonattainment Area

On August 7, 1987 (52 FR 29383), EPA identified a number of areas across the country as PM 10 ‘‘ Group II’’ areas of concern, that is, areas between 20% and 95% likelihood of violating the PM 10 NAAQS. The Columbia Falls PM 10 nonattainment area was identified as a Group II 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. 42 U.S.C. 7407(d)(4)(B). These areas included all former Group II PM 10 planning areas identified on August 7, 1987 (52 FR 29383), and other areas violating the NAAQS for PM 10 prior to January 1, 1989. On October 31, 1990 (55 FR 45799), EPA further clarified the descriptions of Group I and Group II areas of concern listed in the August 7, 1987 (52 FR 29383) notice. 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 Columbia Falls PM 10 nonattainment area was one of these initial moderate PM 10 nonattainment

areas.
i. Attainment Date for the Columbia Falls 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 SIP revision providing for implementation of reasonably available control measures (RACM), including reasonably available control technology (RACT), and a demonstration of whether attainment of


### 5282 Federal Register / Vol. 76, No. 20 / Monday, January 31, 2011 / Rules and Regulations

4 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. the PM 10 NAAQS by the December 31, 1994 attainment date was practicable. See section 189(a).

ii. PM 10 Planning in the Columbia Falls PM 10 Nonattainment Area

After the Columbia Falls PM 10 nonattainment area was designated nonattainment for PM 10 , the Montana Board of Health and Environmental Sciences (MBHES) 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 elements, MBHES developed and implemented control measures on PM 10 sources in the Columbia Falls PM 10 nonattainment area. The Columbia Falls PM 10 SIP was originally adopted by the MBHES on January 24, 1992, and submitted to EPA on May 6, 1992. Deficiencies were identified by EPA and the final technical corrections were submitted to EPA on June 15, 1993. EPA approved the Columbia Falls PM 10 SIP on April 14, 1994, with technical corrections dated June 15, 1993 (59 FR 17700). The State failed to submit the contingency measures by the November 15, 1993, due date. On January 19, 1994, EPA made a finding that the State failed to submit the contingency measures. In response to this finding the Governor of Montana submitted revisions to the SIP for Columbia Falls dated August 26, 1994, to address the contingency measures and EPA approved the revisions on March 19, 1996 (61 FR 11153). C. The Libby 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 Libby 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 42 U.S.C. 7407(d)(4)(B). These areas included all former Group I PM 10 planning areas identified on August 7, 1987 (52 FR 29383), and other areas violating the NAAQS for PM 10 prior to January 1, 1989. On October 31, 1990 (55 FR 45799), EPA further clarified the descriptions of Group I and Group II areas of concern listed in the August 7, 1987 (52 FR 29383) notice. 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 Libby PM 10 nonattainment area was one of these initial moderate PM 10 nonattainment areas. i. Attainment Date for the Libby 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 SIP revision providing implementation of RACM, including 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).

ii. PM 10 Planning in the Libby PM 10 Nonattainment Area

After the Libby PM 10 nonattainment area was designated nonattainment for PM 10 , the MBHES 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 elements, MBHES developed and implemented control measures on PM 10 sources in the Libby PM 10 nonattainment area. The Libby PM 10 SIP was originally adopted by the MBHES on November 15, 1991, and submitted to EPA on November 25, 1991. Deficiencies were identified by EPA and revisions were adopted by MBHES on March 19, 1993, and submitted to EPA on May 24, 1993. Final technical corrections to the SIP were sent to EPA on June 3, 1994. EPA approved the Libby PM 10 SIP, with the exception of the contingency measures, on August 30, 1994 (59 FR 44627). The Governor of Montana submitted revisions to the contingency measures on March 15, 1995 and EPA approved the contingency measures on September 30, 1996 (61 FR 51014).

III. Attainment Determination A. What are the requirements for an attainment determination?

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 in 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; and 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); 4 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 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. B. What do the air quality data show for the Columbia Falls PM 10 nonattainment Area?

Because the Columbia Falls PM 10 nonattainment area had 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 Montana operated one PM 10 SLAMS monitoring site at the Columbia Falls Junior High School, which is within the Columbia Falls nonattainment area. The monitoring site met EPA SLAMS network design and siting requirements set forth at 40 CFR part 58, appendices D and E. The Columbia Falls Junior High School monitor began operation on April 21, 1987 and ceased operation on December 28, 2002.

Our review of complete qualityassured air quality data from the Columbia Falls Junior High School site for the period from January 1, 1992 through December 31, 1994, shows no data values exceeded the level of the 24- hour standard. Because there were no recorded exceedances of the 24-hour


### 5283 Federal Register / Vol. 76, No. 20 / Monday, January 31, 2011 / Rules and Regulations

PM 10 standard during calendar years 1992–1994, the estimated number of PM 10 exceedances for the 1992–1994 period is 0.0, as seen in Figure 1. Therefore, the Columbia Falls nonattainment area has demonstrated attainment for the 24-hour PM 10 NAAQS as of the attainment date of December 31, 1994. Additionally, we evaluated complete quality-assured air quality data at all monitors within the Columbia Falls PM 10 nonattainment area after the attainment date of December 31, 1994 to 2009 and found no recorded exceedances.

C. What do the air quality data show for the Libby PM 10 nonattainment area?
Because the Libby PM 10 nonattainment area had 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 Montana operated two PM 10 SLAMS monitoring sites within the Libby nonattainment area: the Lincoln County Courthouse site and the Libby Courthouse Annex site. Both monitoring sites met EPA SLAMS network design and siting requirements set forth at 40 CFR part 58, appendices D and E. The Lincoln County Courthouse monitor began operation on April 21, 1987 and ceased operation on March 31, 1995. The Libby Courthouse Annex monitor began operating on October 8, 1993 and continues to operate.

Our review of complete qualityassured air quality data from the Lincoln County Courthouse site and the Libby Courthouse Annex site for the period from January 1, 1992 through December 31, 1994, shows no data values exceeded the level of the 24-hour standard. Because there were no recorded exceedances of the 24-hour
PM 10 standard during calendar years 1992–1994, the estimated number of
PM 10 exceedances for the 1992–1994 period is 0.0, as seen in Figure 2. Therefore, the Libby nonattainment area has demonstrated attainment for the 24- hour PM 10 NAAQS as of the attainment date of December 31, 1994. Additionally, we evaluated complete quality-assured air quality data at all monitors within the Libby PM 10 nonattainment area after the attainment date of December 31, 1994 to 2009 and found no recorded exceedances.

IV. EPA’s Final Action

EPA is determining that the Columbia Falls and Libby areas have 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 for both areas is 0.0, which is equal to or less than the expected exceedance rate of 1.0 (40 CFR part 50, appendix K). Because complete quality-assured data for this period shows an expected exceedance rate equal to or below the PM 10 standard, EPA concludes that the areas have met the standard. Pursuant to CAA § 188(c), EPA is required to make a determination of attainment. There were no violations and therefore no health risk. EPA therefore determines that the Columbia Falls and Libby nonattainment areas have attained the 24-hour PM 10 NAAQS as of the December 31, 1994 attainment date. V. Statutory and Executive Order Review

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:

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).

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 April 1, 2011. 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
