AGENCY: Environmental Protection. Agency (EPA). ACTION: Finalrule.

SUMMARY: EPA is approving the Maricopa Association ofGovernments (MAG) serious area carbon monoxide (CO) state implementation plan (SIP) for the Maricopa County CO nonattainment
area, also referred to as "the metropolitan Phoenix area", as meeting the Clean Air Act (CAA) requirements for serious CO nonattainment areas. We

are also approving the MAG CO Redesignation Request andMaintenance Plan forthe Maricopa County CO nonattainment area as meeting CAA requirements forredesignation requests and maintenance plans. In addition,we
are making a boundary change under Section 107 ofthe CAA to take the Gila River Indian Community (GRIC) out of the Maricopa County maintenance area. The portion ofthe Gila River Indian Community which is currently in the Maricopa County CO nonattainment

area willbe "unclassifiable/attainment" forCO, and will notbe subject to the MAG CO Redesignation Request and Maintenance Plan. DATE: Effective Date:This rule is effective April 8, 2005. ADDRESSES: Copies ofthe documents relevant to this action are available for public inspection during normal business hours at EPA Region 9's Air Planning Office (AIR-2), 75 Hawthorne Street, San Francisco, CA 94105-3901.

I. Summary ofEPA's FinalAction

On October 8, 2004 (69FR 60328), we published a notice ofproposed rulemaking forthe State ofArizona. The notice proposed approval ofrevisions to the SIP forthe Maricopa County CO nonattainment area. These revisions to the SIPwere adoptedby the Arizona Department ofEnvironmental Quality (ADEQ). Today, we are finalizing our proposal to approve the MAG serious

area SIP forattainment ofthe CO air quality standard inthe Maricopa County

area. This action is based on our determination that this SIP complies with the CAA's requirements for attainingthe CO standard in serious CO nonattainment areas such asthe metropolitan Phoenix area.

,We are also approving the MAG CO Redesignation Request and Maintenance Plan for the Maricopa County CO nonattainment area as meeting CAA requirements for redesignation requests andmaintenance plans.

We are also making aboundary correction under Section 107 ofthe CAA forthe Gila River Indian Community.

period forthe October 8, 2004, proposal. Two comments were dated October 19, 2004, and one comment was dated November 8, 2004. In addition tothese comments, we received three e-mails submitted after signature but prior to publication ofthe proposal in the Federal Register, two on September 22 and one on September 24, 2004. Since these e-mails raisethe same issues as the comments submitted after publication, we discuss and respondto all ofthem below. The September 24, 2004, e-mail was submitted directly to EPA Administrator Michael Leavitt's office and was referred to EPA Region 9 for aresponse. We determined that the correspondence should be treated as public comment, and respond toithere. (Thiscommentor also sent comments directly to Region 9 on September 22 and 24, 2004). We also received a letter ofsupportfrom ADEQregarding the boundary change for the Gila River Indian Community. Werespond to the comments below in the order we receiVed them.
E-MailsSubmittedtoEPAPrior to the PublicCommentPeriod

We received three e-mails before the October 8 publication ofthe proposed action-two on September 22, and one

on September 24 to Administrator Leavitt.These e-mails, however, solely raise issues unrelated to the action being taken by EPA. Comment.The first e-mailreceived on September 22 stated that the Central Phoenix light rail project will increase the production ofair pollutants due to the prohibition ofleft turns from certain
streets where the trolley tracks will exist. The e-mail refers to an "Air

- Quality Technical Report", and states that 75 percent ofthe vehicles in the Phoenix vehicle mix willbe cars, and 20 percent will be light trucks. This e-mail also refers to a "New Starts Report for 2004", dated December 2003. This report appears torefer to the projected

use ofthe light rail trains.

Response.Our action in this notice will not have any impact whatsoever on the Central Phoenix light rail project. Comment.This e-mail also statesthat the Phoenix area is not in conformity with ozone and PM-10 standards, and that the growth in VMT has exceeded population growth.

Response.Our action today only

concerns carbon monoxide, not ozone or PM-10. Our approval isbased onboth monitored data indicating no violations ofthe CO standard in the past seven years and.modeling whichindicates no expected violations ofthe CO standard
to the year 2015. While growth in VMT has exceeded population growth in Phoenix and other fast-growing metropolitan areas, tailpipe emissions standards atthe national level and the

use ofcleaner-burning fuels and other emissions control measures atthe local levelhave reduced CO emissions sufficiently to attain and maintain Federal ambient air quality standards. Comment.The e-mail refers to.the Final Environmental Impact Statement (FEIS), stating that the FEIS shows that the light rail project will notreduce traffic congestion orthe production of air pollutants inthe lightrail corridor. This e-mail comments that ISTEA and TEA-21 legislation call formaking transit more efficient, and the commenter does notbelieve the Phoenix light rail will increase speeds in the light rail corridor, and will notyield much farebox revenue when compared
to the cost ofmoving light rail -passengers.

Response.Our action today concerns the MAG serious area CO SIP forthe Maricopa County CO nonattainment

area and the MAG CO Redesignation Request and Maintenance Plan forthe Maricopa County CO nonattainment

area. The FEIS forthe Phoenix light rail project is completely unrelated to this action.

Comment.The second e-mail from September 22 states that while MAG reports noviolations ofthe CO standard since 1996, the most recent statistics haven't been applied to air quality modeling, and thatthe light railtrolley hasn't beenproperly factored in.

Response.The Maricopa County CO nonattainment area has monitored clean data every yearbetween 1996 and 2003. This factwas reflected in our finding of attainment published on September 22, 2003, for the Maricopa County CO nonattainment afea (see68FR 55008). MAG's transportation and emissions modeling includes the implementation oflight rail.'

. Comment. The e-mail which was sent to EPA Administrator Leavitt on September 24 states that there is no
reason to believe that the air quality in the Phoenix area currently conforms to Federal standards for CO.

Response.Monitoring data gathered by ADEQ and Maricopa County indicate that the'MaricopaCounty CO nonattainment area has not had a violation of the CO standard since 1996. The area is now in attainment forthe CO Federal health-based standard for CO, based ondata from the years 1999 and 2000. Wenoted this in our finding

Telephone conversation with Cathy Arthur, Maricopa Association ofGovernments, November 19, 2004. ofattainment'(see 68 FR 55008, page 55009, 3rd column).

Comment,The September 24 e-mail also states that our finding ofattainment ofthe CO standard for theMaricopa County nonattainment area (68 FR 55008) reflects only data through 1999.

Response.The finding ofattainment

was based on monitoring data from the years 1999 and 2000 because 2000 was the attainment yearfor the Maricopa County serious CO nonattainment area. (See 68 FR55008, September 22, 2003.) Section 179(c)(1) ofthe Clean Air Act provides that attainment determinations

are to bebased upon an area's "air quality as ofthe attainment date". Monitoring data gathered byADEQ and Maricopa County since that time indicate that the Maricopa County CO nonattainment areahas nothad a violation of the CO standard since 1996,

so current data have beenreviewed and taken into account in our action today.

Comment.The September 24 e-mail questions how the CO standard canbe metgiven the rapid increase in population and an even faster increase inVMT in the Maricopa County nonattainment area. The e-mail states. that Maricopa County's population has beenincreasing 45 percent every 10 years inrecent decadds.

Response.MAG's data estimate about

a 32 percent increase in population between 2004 and 2015. As indicated in. the Appendix to the MAGCO Redesignation Request and Maintenance Plan, while VMT doubles between 1995 and 2015, CO emissions decrease. MAG's models properly account for the growth inVMT.
E-MailsSubmittedtoEPADuringthe PublicCommentPeriod

Comment.The first e-mail dated October 19, 2004, asks how it can be possible toreduce CO emissions by half by 2015 assuming 1.2 million additional residents, 700,00g-800,000 more vehicles, and additional airplanes and diesel trucks in the'Phoenix metropolitan area.

Response.MAG's modeling estimates

a 14 percent reduction inCO between 1994 and 2015 and is sufficient to maintain the ambient air quality standard for CO. Tier 2 emissions standards, cleaner burning gasoline, and other measures provide reductions which outweigh the increases in emissions due to vehicle miles travelled. Comment.The first October 19 e-mail refers to aDraft Environmental Impact Statement (DEIS) inan air quality conformity report.

Response.This comment is not relevant to today's action.

HeinOnline -- 70 Fed. Reg. 11554 2005Federal Register/Vol. 70,. No. 45/Wednesday, March 9, 2005/Rules and Regulations

Comment.This same e-mail questioned the CO reductions attributed
to oxidants and sulfur in fuel, again in

aDEIS.

Response.-Itis notclear which project DEIS isreferred toby the commenter. MAG used the MOBILE6 model, which is the model EPA requires all states except California to use for SIP development. The MOBILE model
accounts forfuel properties such as oxidants and sulfur, and reduces the effects ofoxidants on CO emissions over time. Most newer cars are equipped with electronic fuel injection systems that generally automatically compensate forthe proper air-to-fuel mixture to reduce'COemissions.

Comment.This same e-mailrefers to

a "new standard for CO" that requires

an 8-hour test, and refersto calm days inthe summerwhen CO could be a problem.

Response.There is nonew standard forCO; we assume the commentrefers
to the new 8-hour ozone standard.CO tends tobe a wintertime problem, and CO emissions do not tendto be high in the summer.

Comment.The letter we received on October 19via U.S. Mail questioned our proposed boundary change forthe Gila River Indian Reservation. This letter indicated that the Gila River Indian Community is planning a large truck stop alongthe Reservation border with the Phoenix metropolitan area, as well

as substantial development along the northern border ofthereservation.

Response.Our proposal to change the boundary ofthe Phoenix CO maintenance area to remove GRIC was based onmonitored air quality data,
current emissions levels and sources, and planning considerations. The
commenter has not provided any reliable facts about development on the Gila River Indian Reservation that would affect ambient CO concentrations
to a degree sufficient to violate the NAAQS. In particular, diesel trucks idling at a truck stop would emit primarily particulate matter (PM)and nitrogen oxides, not CO. GRIC Department ofEnvironmental Quality staffhave indicated they are looking into truck stop electrification to reduce the impacts ofidling trucks.2

Comment.The October 19 letter also questioned whetherEPA established air quality monitoring stations on the Reservation or whether we relied on data fromthe GRIC. The e-mail asserts that the monitors and data were distorted for the purpose ofattaining the boundary change.

2 Telephone'conservation withJanetTravis, GRIC DEQ, December 2, 2004. Response.The commenter has provided only speculation, without any reliable facts to substantiate the claim.

Comment.Finally, the October letter asserts that the entire premise ofa status change is faulty andbiased.

Response.As stated earlier, the
commenter has provided-only speculation, without any reliable facts
to substantiate the claim.

Comment.The e-mail dated November 8 asserts that MAG's Transportation Improvement Program (TIP) andLong Range Transportation Plan (LRTP) are deficient and not worthy ofCO redesignation. The e-mail also raises a concern that the public needs to be protected infast-growing

areas like Maricopa County, and states that CMAQ funding should notbe used forthe Central Phoenix LightRail Project.

Response.This comment raises issues unrelated to EPA's action. Our proposed approval ofMAG's CO redesignation request and maintenance plan is an action on MAG's SIP revision, not on the TIPor LRTP. MAG has demonstrated through air quality modeling that the Maricopa County CO nonattainment area will stay below federal air quality standards until 2015. In this way, public healthwill be protected.

Regarding CMAQ funding, while EPA mayreview and comment onCMAQ funding proposals, final funding decisions aremade by other agencies.

Comment.The November 8 e-mail also states that MAG uses flawed and old models, referring to the base year 1994 inventory which MAG used, EPA's MOBILE6 model, and the CO Complex model. This e-mail also states that oxygenated fuels increase aldehydes.

Response.While MAG used a base year 1994 inventory, the redesignation request andmaintenance plan also contains emissions inventories for 1998, 1999, 2006, and 2015. We have reviewed these inventories and have found them to be complete, accurate, and current. EPA's3MOBILE6 model is the modelrequired to be used by all
states except California forSIP development. Studies ofair toxics from

sources such as gasoline are currently underway atthe national level, but there is currently no health standard for aldehydes.

Comment.This same e-mail states that the rapid growth inthe MAG region will increase VMT, and that MAG's computer models donot properly incorporate these factors.

Response.As indicated in the Appendix tothe MAG CO Redesignation Request andMaintenancePlan, while VMT doubles between 1995 and 2015, CO emissions decrease. MAG's models properly account forthis growth inVMT.
III. EPA'sFinalAction

In today's action, we are approving the MAG Serious Area CO SIP forthe Maricopa County.CO norattainment

area andthe MAG CO Redesignation Request andMaintenance Plan forthe Maricopa County CO nonattainment

area. We have evaluated the submitted SIP revisions and have determined that they are.consistent with the CAA and EPA regulations.

We are approving the following 'elements ofthe Revised 1999 CO Plan for the metropolitan Phoenix area and the MAG CO Redesignation Request and Maintenance Planinto the Arizona SIP:

1. 1990base year and 1993 and 1996 periodic emission inventories as required by sections 172(c)(3) and 187(a)(5).

2. Demonstration that the plan provides forthe implementation of reasonably available control measures including transportation control

measures under sections 172(c)(1) and 187(b)(2);

3.Demonstration ofattainment by December 31, 2000, under section 187(a)(7);

4. Demonstration ofreasonable further
progress under sections 172(c)(2) and 187(a)(7);

5.Contingency measures under sections 172(c)(9) and 187(a)(3);

6. Forecasts ofvehicle miles traveled andprovisions for annual tracking and reporting under section 187(a)(2)(A);

7.Transportation control measures as necessary to offset growth inemissions under section 187(b)(2);

8. Attainment year and projected emissions inventories under section 175A;

9. Air quality monitoring requirements under section 110(a)(2) and section 172(c)(7);

10. CO motor vehicle emissions budgets for transportation conformity under section 176(c) forthe attainment demonstration and themaintenance plan forthe years 2000, 2006 and 2015 under the transportation conformity rule, 40 CFR part 93, subpart A;

12. Demonstration ofmaintenance under section 175A(a) and a.fullyapproved maintenance planunder section 175A;

. 13. Maintenance plan contingency

measures under section 175A(d); 14. Commitment for subsequent maintenance plan revisions under section 175A(b);

15. Redesignation ofthat portion of theGila RiverIndian Reservation that is

now within the nonattainment area to "nonclassifiable/attainment'; and

HeinOnline -- 70 Fed. Reg. 11555 200511556 Federal Register /Vol. 70, No. 45 /Wednesday, March 9, 2005 /Rules and Regulations

16. A determination-that the improvement in air quality in the Maricopa County nonattainment area is due to permanent and enforceable reductions in emissions resulting from the implementation ofthe applicable implementation plan, implementation ofapplicable Federal airpollution control regulations, and other permanent and enforceable reductions.

Wehave previously approved the principal control measures relied on for attainment and contingency measures in the Revised 1999 CO Plan, including the area's enhanced inspection and maintenance program (required by section 187(a)(6)), oxygenated gasoline program (required by sections 187(b)(3) and 211(m)), and woodburning curtailment regulations. See 68 FR 2912, 69 FR 10161,.64 FR 60678 and 67 FR 52416.

Nothing inthis action should be construed as permitting orallowing or establishing a precedent for any future implementation plan..Each request for revision to a state implementation plan shallbe considered separately in light of specific technical, economic, and environmental factors and inrelation to relevant statutory and regulatory requirements.

IV. Statutory and Executive OrderReviewsUnderExecutive Order 12866 (58 FR 51735, October 4, 1993), this action is not a"signifi6ant regulatory action" and therefore is not subject to review bythe Office ofManagement and Budget. For thisreason, this action is also not subject to Executive Order 13211, "Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, orUse" (66 FR 28355, May 22, 2001). This action merelyapproves
state law asmeeting Federal requirements and imposes no additional requirements beyond those imposedby state law. Accordingly, the Administrator certifies that this rule willnot have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act(5 U.S.C. 601 etseq.).Because this rule approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it does not contain any unfunded mandate or significantly or uniquely affect small governments, as described inthe Unfunded Mandates Reform Act'of 1995 (Pub.L. 104-4).

Executive Order 13175, entitled "Consultation and Coordination with Indian Tribal Governments" (65 FR 67249, November 6, 2000), requires EPA to develop an accountable process to ensure "meaningful and timely inputby tribal officials in the development of regulatory policies that have tribal implications." "Policies that have tribal implications" are defined inthe Executive Orderto include regulations

- that have "substantial direct effects on

one or moreIndian tribes, on the relationship between the Federal government and the Indian tribes, or on the distribution ofpower and responsibilities between the Federal *government and Indian tribes." Under section 5(b) ofExecutivd Order 13175, EPA may not issuea regulation that has tribal implications, that
"imposes substantial direct compliance

costs, andthat is notrequired by statute, unless the Federal government provides the funds necessary topay the direct* compliance costs incurred bytribal governments, orEPA consultswith tribal officials early in the process of developing the proposedregulation. Under section 5(c) ofExecutive Order 13175, EPA may notissue a regulation that has tribal implications and that preempts tribal law,unless the Agency consults with tribal officials early in the process ofdeveloping the proposed regulation.

EPA has concluded that this final rule may have tribal implications. EPA's action will removethe GilaRiver Indian Community from the Phoenix CO maintenance area. However, it will neither impose substantial direct compliance costs on tribal governments,.

norpreempt State law. Thus, the requirements ofsections 5(b) and 5(c) of the Executive Order donot apply to this rule.

Consistent with EPA policy, EPA nonetheless consulted with representatives oftribal governments early in the process of developing this regulation topermit them to have meaningful andtimely input into its development. Representatives oftribal governments approached EPA two years ago and requested that EPA make this boundary change. We agree with the technical andpolicy rationale the tribe Provided, and believe that all tribal

concerns have been met. Moreover, in the spirit ofExecutive Order 13175, and consistent with EPA policy to promote communications between EPA and tribal governments, EPA specifically solicited comment on the proposed rule from tribal officials.

This action also does nothave Federalism implications because it does. nothave substantial direct effects on the States, ontherelationship between the national government and the States, or
onthe distribution ofpower and responsibilities among the various levels ofgovernment, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely approves a state rule implementing a Federal standard, and doesnot alterthe relationship orthe distribution ofpower and responsibilities established in the Clean Air Act. This rule also is not subject to Executive Order 13045 "Protection ofChildren from Environmental Health Risks and Safety Risks" (62 FR 19885, April 23, 1997), because it is noteconomically significant.

Inreviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. In thiscontext, in the absence ofa prior existing requirement forthe State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure touse VCS. Itwould thus be inconsistent with applicable law for EPA, when itreviews a SIP submission,
to use VCS in place ofa SIP submission that otherwise satisfies the provisions of the Clean Air Act. Thus,the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15U.S.C. 272 note) do not apply. Thisrule does
notimpose an.information collection burden under theprovisions ofthe Paperwork Reduction Actof 1995 (44 U.S.C. 3501 etseq.).

The Congressional Review Act, 5 U.S.C. 801 etseq., as added bythe Small Business Regulatory Enforcement Fairness Actof 1996, generally provides thatbefore 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 andto 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 topublication ofthe rule in the Federal Register. Amajorrule cannot take effect until 60 days after it ispublished in the Federal Register. This action is not a "majpr rule" as defined by 5U.S.C. 804(2).

Under section 307(b)(1) ofthe Clean AirAct,'petitions forjudicial review of this action mustbe filed in the United States Court ofAppeals for the appropriate circuit byMay 9, 2005. Filing a petition for reconsideration by the Administrator ofthisfinal rule does
notaffect the finality ofthisrule forthe purposes ofjudicial review nor dioes it extendthe time within which a petition forjudicial review may be filed, and shallnot postpone the effectiveness of such rule oraction. This action maynot be challenged laterin proceedings to
