AGENCY: Environmental Protection Agency (EPA). ACTION: Direct final rule.

SUMMARY: EPA is taking direct final, action under the Clean Air Act to determine that theYuma nonattainment

area in Arizona has attained the National Ambient Air Quality Standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal
to anominal 10 micrometers (PM10). This determination is based upon monitored air quality data for thePM1o NAAQS during the years 1998-2000. EPA also finds that the Yuma area is currently in attainment ofthe PM1o NAAQS, and based on this finding, EPA is determining that certain Clean Air Act requirements are not applicable for

so long as the Yuma area continues to attain the PMIo NAAQS. DATES: This rule is effective on May 15, 2006, without further notice, unless EPA receives adverse comments by April 13, 2006.

A. WhatNationalAmbientAir Quality Standards(NAAQS) Are Considered in Today'sFinding?



### Particulate matter with an aerodynamic diameter ofless than or equal to 10 micrometers (PMI 0) is the subject ofthis action. The NAAQS are limits 'for certain ambient air pollutants
set by EPA to protect public health and welfare. PMIo is among the ambient air

pollutants for which EPAhas established ahealth-based standard.

PMlo causes adverse health effects by penetrating deep into the lungs, aggravating the cardiopulmonary system. Children, the elderly, and people with asthma and heart conditions are the most vulnerable.

On July 1, 1987 (52 FR 24634), EPA revised theNAAQS for particulate
matter with an indticator that includes only those particles with an aerodynamic diameter less than or equal
to a nominal 10 micrometers. See 40 CFR 50.6. The 24-hour primary PMlo standard is 150 micrograms per cubic
meter gig/m 3 with no more than one expected exceedance per year. The annual primary PM10 standard is 50jg/ M3 as an annual arithmetic mean. The secondary PMlo standards, promulgated
to protect against adverse welfare effects, are identical to the primary standards.

B. WhatIs theDesignationand ClassificationofThis PMo Nonattainment Area? Upon enactment ofthe 1990 Clean Air Act Amendments (CAA or "Act"), PMjo

areas meeting the requirements ofeither (i) or (ii)of section 107(d)(4)(B) ofthe Act were designated nonattainment for PM 1oby operation oflaw and classified "moderate." These areas included all former Group IPM 1o 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 PMjo prior to January 1, 1989 (many ofthese

areas were identified by footnote 4 in the October 31, 1990 FederalRegister document). A Federal Register notice announcing the areas designated nonattainment for PM1o upon enactment ofthe 1990 Act Amendments, known as "initial" PMlo nonattainment areas, was published on March 15, 1991 (56 FR 11101). A subsequent Federal Register document correcting some ofthese areas

was published on August 8, 1991 (56 FR 37654). These nonattainment designations and moderate area classifications were codified in 40 CFR part 81 in a Federal Register document published on November 6, 1991. (56 FR 56694). Allother areas in the nation not designated nonattainment at enactment

were designated unclassifiable (see section 107(d)(4)(B)(iii) of theAct).

The Yuma plaming area was listed by EPA as a Group I area (see 52 FR 29383, August 7, 1987) and was designated nonattainment for PM10,byoperation of law and classified "moderate." In accordance with section 189(a)(2) of the CAA, Arizona was to submit a state implementation plan (SIP)by November 15, 1991 demonstrating attainment of the PM ostandards by December 31, 1994 for the Yuma area.'

C.HowDo We MakeAttainment Determinations?

Pursuant to sections 179(c)(1) and 188(b)(2) ofthe Act, we have the responsibility ofdetermining within six months ofthe applicable attainment date whether, based on air quality data, PM1o nonattainment areas attained the NAAQS by that date. The "applicable attainment date" is December 31, 1994 for areas, such as Yuma, that were designated as "moderate" nonattainment for PMo by operation of law under the 1990 Amended Act. Determinations under section 179(c)(1) ofthe Act are to bebased upon an area's "air quality as ofthe attainment date." Section 188(b)(2) is consistent with this requirement.

Generally, we will determine whether

an area's air quality meets the PM10 NAAQS for purposes ofsection 179(c)(1) and 188(b)(2) based upon data gathered at established state and local air monitoring stations (SLAMS) and national air monitoring stations (NAMS) in the nonattainment area and entered into the EPA's Air Quality System (AQS) database. Data entered into the AQS has been determined to meet federal monitoring requirements (see40 CFR 50.6; 40 CFR part 50, appendix J; 40 CFRpart 53; 40 CFR part 58, appendices A and B) and maybe used
to determine the attainment status of

areas. We 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. All data are reviewed to determine the area's air quality status in accordance with our guidance at 40 CFR part 50, Appendix K.Attainment ofthe annual PM~o standard is achieved when the annual arithmetic mean PM1o concentration

over a three-year period is equal to or less than 50 jig/m 3

. Attainment ofthe 24-hour standard is determined by calculating the expected number ofdays in a year with PM10 concentrations greater than 150 jig/m 3

. The 24-hour standard is attained when the expected number ofdays per year with levels above 150 jig/m 3 (averaged over a threeyear period) is less than or equal to one. Three consecutive years ofair quality data are necessary to show attainment of

Arizona submitted amoderate area plan for the Yuma area on November 14, 1991; EPA found this plan to be incomplete on May 14, 1992. Arizona submitted a revised plan for Yuma on July 12, 1994. EPA found the revised plan to be complete but has
not taken action onit. the 24-hour and annual standards for PM1o.See 40 CFR part 50 and appendix K. A complete year ofair quality data,

as referred to in40 CFR part 50 Appendix K, includes all 4 calendar quarters with each quarter containing data from atleast 75 percent ofthe scheduled sampling days. 2

II. WhatIs the Basis for EPA's Determination That the Yuma Nonattainment Area Has Attained the PM 10 NAAQS?
The Yuma PM 10 nonattainment area is located in the lower Colorado River Valley inthe southwestern portion of Yuma County. The PM~o nonattainment

area consists of 456 square miles, which is roughly eight percent ofthe land area ofYuma County (5,500 square miles). Yuma County is located in the southwestern portion ofArizona that borders California and Mexico. The cities ofYuma and Somerton are the largest population centers in the Yuma PM10 nonattainment area. The city of Yuma, the county seat, is located below the convergence ofthe Gila and Colorado Rivers on the far western side ofthe PM10 nonattainment area. The city of Somerton is located in the southwestern portion of the PM10 nonattainment area. Agriculture is the primary industry in Yuma County. The Arizona Department ofEconomic Security predicts that Yuma County's population is expected to increase by 37.5 percent from 138,025 in 2000 to 189,783 in 2015.3 Approximately onehalf ofthe county's year-round population resides in the city ofYuma. During the winter, Yuma County's population increases significantly due
to seasonal residents.

The Yuma PM1o nonattainment area has one SLAMS monitor operated by the Arizona Department ofEnvironmental Quality (ADEQ). This monitor was located at the Yuma County Juvenile Center in the city ofYuma from 1986 until the second quarter of2002, after which time it was relocated to the nearby Yuma County Courthouse, which is also located in the city of Yuma. ADEQ measures ambient (24- hour-average) PMio concentrations in Yuma at a frequency of once every six days.

Table 1 summarizes the PMo data collected in Yuma from 1992-2005 and reported by ADEQto the AQS database. Table 1also indicates which years had

IThe data summary inTable 1includes substituted data and was analyzed according to the "Guideline on Exceptions to Data Requirements for Determining Attainment of Particulate Matter Standards." See footnote 4.The fourth quarter in 1994, the secondquarter in 1997, and the first and fourth quarters in2001 were not eligible for data substitution. The incomplete datafrom these quarters was included inthe calculation of the annual average for each ofthese years.

2The highest measured 24-hour-average concentration in2001 was 150 .tg/m3

, which is equal to the 24-hour PMj0 NAAQS, but which isnot considered an "exceedance." Under EPA regulations, an exceedance of the 24-hour-average standard represents concentrations of 155 hg/m3

or greater. See 40 CFR 50, appendix K.

3Data substitutio results ina conservative estimate of the annual average. See footnote 4. For example, the annual average for 2000 of 54.3 gg/m 3 would be reduced to 42.3 ,ug/m3 if data substition was not used. The method of data substitution was used to calculate annual averages for 1993-1997, 2000-2002, and 2004.

4We have received AQS datafrom ADEQ through September 30, 2005. States are required to report data to AOS on a rolling basis and have until 90 days from the end of agiven quarter to submit quality-assured monitoring data into AQS. See 40 CFR 58.28.

NA: Not Applicable.

Like the 1992-1994 period, the series ofthree-year periods immediately following 1992-1994 also show no exceedances ofthe PM1oNAAQS but an incomplete data set in 1997 prevents us from making an attainment finding until 1998-2000, the first three-year period * after the applicable attainment date with sufficient data capture to make an attainment finding consistent with 40 CFR Part 50, Appendix K.

As noted above, the 24-hour PM 10 standard is attained when the expected number ofdays per year with levels above 150 gg/m 3 (averaged over a threeyear period) is less than or equal to one. When we apply data substitution per' the above-referenced guideline for the period 1998-2000, we find no exceedances ofthe 24-hour PMo NAAQS forthe 1998-2000 period and thus the expected number ofdays per year with levels above 150 gtg/m 3 (averaged overthat three-year period) is

zero. As such, pursuant to sections 179(c)(1) and 188(b)(2) ofthe Act, we find that Yuma has attained the 24-hour PM10 NAAQS. Since 2000, there is one year (2001) in which four complete quarters of data are not available, but

4The regulatory requirement for data capture in 40 CFRpart 50, Appendix K, is75 percent on a quarterly basis. According to the "Guideline on Exceptions to DataRequirements forDetermining Attainment ofParticulate Matter Standards" (see EPA document450/4-87-005, April 1987),when data capture is at least 50 percent butless than 75 percent, data may be substituted for themissing data. Perthe above-referenced guideline, monitoring data from the same quarter in any one because the data from the most recent three-year period (2002-2004) are complete and show no exceedances, 5
and because the latest available information for 2005 also reveals no exceedances, we conclude that Yuma is currently in attainment ofthe 24-hour PMio NAAQS.

Also as noted above, attainment ofthe annual PM 1 ostandard is achieved when the annual arithmetic mean PM 10 concentration over a three-year period is equal to or less than 50 gg/m 3

.Review ofthe data for calendar years 1998-2000 reveals an arithmetic average of43.6 JRg/ M3

. As such, pursuant to sections 179(c)(1) and 188(b)(2) ofthe Act, we find that Yuma has attained the annual PM10 NAAQS. As noted previously, the data set for year 2001 is not complete, but the data from the most recent complete three-year period (2002-2004) show that Yuma is currently in attainment ofthe annual PM10 NAAQS.

ofthe years used to determine attainment may be substituted for missing PM io data. The maximum PMo value that was observed in that quarter over the last three years is substituted for missing scheduled sampling days.

What Are the Applicable Planning Requirements for the Yuma Nonattainment Area as a Result of EPA's AttainmentDetermination?

The air quality planning requirements for moderate PM 0 nonattainment areas, such as the Yuma nonattainment area,
are set out inpart D, subparts 1 and 4 oftitle I ofthe Act. We have issued guidance in aGeneral Preamble 6 describing how we will review SIPs and SIP revisions submitted under title Iof the Act, including those containing moderate PM1o nonattainment area SIP provisions.

In nonattainment areas where monitored data demonstrates that the NAAQS have already been achieved, EPA has determined hat certain requirements ofpart D, subparts 1and 2 oftitle I ofthe Act (with respect to 1- hour ozone) do not apply. Therefore, we do not require certain submissions for

an area that has attained the NAAQS. These include reasonable further progress (RFP)requirements, attainment demonstrations and contingency
measures, because these provisions have the purpose ofhelping achieve attainment ofthe NAAQS.

on that date. ADEQ has prepared a Natural Events Action Plan [NEAP) in response to that event. The NEAP includes the development and implementation ofBest Available Control Measures (BACM) for anthropogenic PMo sources that contributed to the event.

### 13023

HeinOnline -- 71 Fed. Reg. 13023 2006Federal Register/Vol. 71, No. 49/Tuesday, March 14, 2006/Rules and Regulations

This interpretation ofthe CAA is known as the Clean Data Policy and is the subject oftwo EPA memoranda. EPA also finalized the statutory interpretation set forth in the policy in

a final rule, 40 CFR 51.918, as part of its "Final Rule to Implement the 8-hour Ozone National Ambient Air Quality Standard-Phase 2" (Phase 2 Final Rule). See discussion inthe preamble to the'rule at 70 FR 71612, 71645-46 (November 29, 2005). EPA believes that the legal bases set forth in detail in our Phase 2 Final Rule, our May 10, 1995 memorandum from John S. Seitz, entitled "Reasonable Further Progress, Attainment Demonstration, and Related Requirements for Ozone Nonattainment Areas Meeting the Ozone National Ambient Air Quality Standard," and our December 14, 2004 memorandum from Stephen D. Page entitled "Clean Data Policy forthe Fine Particle National Ambient Air Quality Standards" are equally pertinent to the interpretation of provisions ofsubparts 1and 4 applicable to PM10. Our interpretation that an area that is attaining the standards is relieved ofobligations to demonstrate RFP and toprovide an attainment demonstration and contingency measures pursuant to part D of the CAA, pertains whether the standard is PM1o, ozone or PM2 .5. 7 It hasbeen EPA's longstanding interpretation that the general provisions ofpart D, subpart 1 ofthe Act (sections 171 and 172) do not require the submission ofSIP revisions concerning RFP for areas already attaining the ozoneNAAQS because the stated purpose of-RFP is-to ensure attainment by the applicable date. 57 FR at 13564. EPA believes the same reasoning applies to the PM 1oprovisions ofpart D, subpart 4. CAA section 189(c)(1), applicable to PM10 nonattainment areas, states that revisions shall contain milestones which are to be achieved until the area is redesignated to attainment, such milestones are designed to show reasonable further progress "toward attainment by the applicable date," as defined by section 171. Thus, it is clear that once the area has attained the standard, no further milestones are necessary ormeaningful.

With respectto the attainment demonstration requirements ofsection 189(a)(1)(B) an analogous rationale leads to the same result. CAA section

7Three U.S. Circuit Courts ofAppeals have upheld EPA rulemakings applying its interpretation of subparts 1and 2 with respect to ozone. Sierra Clubv. EPA, 99 F.3d 1551 (loth Cir. 1996); Sierra

- Clubv. EPA, 375 F.3d 537 (7th Cir. 2004); Our Children's EarthFoundationv.EPA, No. 04-73032 (9th Cir.June 28, 2005) (memorandum opinion). 189(a)(1)(B), requires that the plan provide for "a demonstration (including airquality modeling) that the [SIP] will provide for attainment by the applicable attainment date * * *"As with the RFP requirements, ifan areais already monitoring attainment ofthe standards, EPA believes there is no need for an
area to make a further submission containing additional measures to achieve attainment. This is also consistent with the interpretation ofthe section 172(c) requirements provided by EPA in the General Preamble (57 at 13564), the December 14, 2004 memorandum, and the section 182(b) and (c) requirements set forth in the May 10, 1995 memorandum.

- Other SIP submission requirements

are linked with these attainment demonstration and RFP requirements, and similar reasoning applies to them. These requirements include the contingency measure requirements of section 172(c)(9) and 182(c)(9). We have interpreted the contingency measure requirements ofsection 172(c)(9) and 182(c)(9) as no longer applying when an
area has attained the standard because those "contingency measures are directed at ensuring RFP and attainment by the applicable date." (57 FR at 13564); May 10, 1995 memorandum at 5-6.

Here, as in both our Phase 2 Final Rule and ozone and PM 2. 5 clean data memoranda, we emphasize that the suspension ofa requirement to submit SIP revisions concerning these RFP, attainment demonstration, contingency, and other related requirements exists only for as long as a nonattainment area continues to monitor attainment ofthe standard. Ifsuch an area experiences a violation ofthe NAAQS, the basis for the requirements being suspended would uo longer exist. Therefore, should EPA at some future time determine that an area that had clean data,but which has not yet been redesignated as attainment for a NAAQS, has violated the relevant standard, the State would again be required to submit the pertinent CAA requirements forthe area.

With respect to the Yuma PM1o nonattainment area, based on the finding made herein that Yuma is currently in attainment ofthe PM 10 NAAQS and based on the rationale given above, we have determined that the part D, subpart 4 obligations to provide an attainment demonstration pursuant to section 189(a)(1)(B), the RFP provisions established by section 189(c)(1), and the attainment demonstration, RFP and contingency

measure provisions ofpart D, subpart 1 contained in section 172 ofthe Act are not applicable for so long as the Yuma

area continues to monitor attainment of the PM1 0 NAAQS. If measurements of ambient PM10 concentrations in the Yuma area reveal a violation ofthe PM1 0 NAAQS, then the State ofArizona would again be required to submit the pertinent CAA requirements for.this nonattainment area. 8

IV. EPA's FinalAction

Based on quality-assured data meeting the requirements of40 CFR part 50, appendix K, we findthat the Yuma, Arizona nonattainment area has attained the PM 1 0 NAAQS. This action is a finding ofattainment under sections 179(c)(1) and 188(b)(2) ofthe Clean Air Act and not a redesignation to attainment under CAA section 107(d)(3) because we have not yet approved a maintenance plan meeting the requirements ofsection 175A ofthe CAA or determined that the area has met the other CAA requirements for redesignation. The classification and designation status in 40 CFR part 81 will remain moderate nonattainment for this area until such time as Arizona meets the CAA requirements for redesignation ofthe Yuma PM10 area to attainment.

EPA also finds that, because the Yuma "moderate" nonattaimnent area is currently in attainment ofthe PM10 NAAQS, the following CAA requirements are not applicable for so long as the area continues to attain the PM1 0 NAAQS: the part D, subpart 4 obligations to provide an attainment demonstration pursuant to section 189(a)(1)(B), the RFP provisions established by section 189(c)(1), and the attainment demonstration, RFP and contingency measure provisions ofpart D, subpart 1 contained in section 172 of the Act.

We are publishing this rule without prior proposal because the Agency views this as anoncontroversial action and anticipates no adverse comments. However, in the proposed rules section

8 Note, however, that onJanuary 17, 2006, EPA published proposedrevisions to the NAAQS for particulate matter. See http://www.epa.gov/fedrgstr/ EPA-AIR/2006/January/Day-17/. The proposed revisions address two categories ofparticulate matter: fine particles which are particles 2.5 micrometers in diameter and smaller; and "inhalable coarse" particles which are particles between 2.5 and 10 micrometers (PMo-2,5s}. Upon finalization ofa primary 24-hour standard for PM1e-2.5, EPAproposestorevoke the current24- hourPM,0 standard in all areas ofthe country except in areas where there is at least one monitor located in an urbanized area (as defined bythe U.S. Bureau ofthe Census) with a minimum population of 100,000 that violates the current 24-hour PM1a standardbased onthe most recent three years of data. In addition, EPA proposes to revoke the current annual PM 0 standard upon finalization of

a primary 24-hour standard for PMI-2.5.

V. Statutory and Executive Order Reviews

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a "significant regulatory action" and therefore is not subject to review by the Office ofManagement 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" (66FR 28355,, May 22, 2001). This action merely makes a determination based on air quality data and does not impose any additional requirements. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number ofsmall entities underthe Regulatory Flexibility Act (5 U.S.C. 601 etseq.). Because this rule does not impose any additional enforceable duty, 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 rule also does nothave tribal implicationsbecause it will not have a substantial direct effect on one or more Indian tribes, on therelationship 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 97249,November 9, 2000). This action also does not have federalism implications because it does nothave substantial direct effects on the States,

on the relationship between the national government and the States, or on the distribution ofpower and responsibilities among the various levels ofgovernment, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely makes a determination based on air quality data and does not alter the relationship orthe distribution ofpower and responsibilities established inthe CAA. This 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 is not economically significant.

The requirements ofsection 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does notimpose an informatioh collection burden under the provisions ofthe Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

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 arule report, which includes a copy ofthe rule, to each House ofthe Congress and to the Comptroller General ofthe United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House ofRepresentatives, and the Comptroller General ofthe United States prior to publication ofthe rule in the Federal Register. A major rule
cannot take effect until 60 days after it is published inthe Federal Register. This action is not a "major rule" as definedby 5 U.S.C. 804(2).

Under section 307(b)(1) ofthe CAA, petitions forjudicial review ofthis action mustbe.filed in the United States Cour ofAppeals for the appropriate circuit by May 15, 2006. Filing a petition for reconsideration by the Administrator ofthis final rule does not affect the finality ofthis rule for the purposes ofjudicial review nor does it extend thetime within which a petition forjudicial review may be filed, and shall notpostpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
