1 For both the 1-hour and 8-hour ozone standards,EPA has promulgated secondary standards that areidentical to the primary standard. Because theprimary and secondary standards are identical, EPArefers to the 1-hour and 8-hour standards in thesingular. However, both EPA’s initial ruledetermining that the 1-hour standard no longerapplied and this rule reinstating the applicability ofthat standard apply for purposes of both theprimary and secondary 1-hour ozone standards.Similarly, EPA’s references to the 8-hour standardencompass both the primary and secondary 8-hourstandards.

Rescinding Findings That the 1-HourOzone Standard No Longer Applies inCertain Areas

AGENCY: Environmental ProtectionAgency (EPA).ACTION: Final rule.

SUMMARY: Today, EPA is rescinding itsprior findings that the 1-hour ozonenational ambient air quality standard(NAAQS) and the accompanyingdesignations and classifications nolonger apply in certain areas. As part ofa transition to a new, more protective 8-hour ozone standard (promulgated inJuly 1997), in 1998 and 1999, EPA tookfinal action determining that the 1-hourstandard would no longer apply inalmost 3,000 counties. Now, however,the public health protection that wouldbe afforded by the 8-hour ozonestandard is being delayed becausecontinued litigation regarding the 8-hour ozone standard has createduncertainty regarding when andwhether EPA may be able to fullyimplement that standard. It is importantto have a fully enforceable Federalozone standard to help protect peoplefrom the respiratory and other harmfuleffects of ozone pollution. Under thisfinal rule, the designations andclassifications that previously appliedin such areas with respect to the 1-hourstandard would also be reinstated. Thisrule will become effective in 90 days formost areas, and will become applicablein 180 days for areas with clean airquality data that had a nonattainmentdesignation when the 1-hour standardwas revoked. Furthermore, today EPA istaking final action to amend 40 CFR50.9(b) to provide by rule that the 1-hour ozone standard will continue toapply to all areas notwithstandingpromulgation of the 8-hour ozonestandard; and that after the 8-hourstandard has become fully enforceableunder part D of title I of the Clean AirAct (CAA) and is no longer subject tofurther legal challenge, the 1-hourstandard set forth in section 50.9(a) willno longer apply to an area once EPAdetermines that the area has air qualitymeeting the 1-hour standard.DATES: Effective Date: This rule iseffective on October 18, 2000.

Applicability Dates: This rule applieson October 18, 2000 for all areas whereEPA had revoked the 1-hour ozone

standard except for those nonattainmentareas with clean data listed in sectionIII. F., Table 1 of the preamble, andapplies on January 16, 2001 for suchareas listed in Table 1 of the preamble.ADDRESSES: Public Inspection.

I. Background

The EPA promulgated a revised 8-hour ozone standard in July 1997 1 (62FR 38856, July 18, 1997). At that time,EPA also promulgated 40 CFR 50.9(b),governing when the previous health-based ozone standard—the 1-hourstandard—would no longer apply toareas. Several parties challenged EPA’srevised ozone standard and EPA’srevised particulate matter standard,which was promulgated on the sameday. American Trucking Assoc. v. EPA,(D.C. Cir., Nos. 97–1440 and 97–1441)(ATA v. EPA).


45183Federal Register / Vol. 65, No. 140 / Thursday, July 20, 2000 / Rules and Regulations

2 Two of these final actions were challenged andthese cases are currently pending. EnvironmentalDefense Fund v. EPA, (D.C. Cir., No. 98–1363)(challenge to June 1998 final rule); AppalachianMountain Club v. EPA, (1st Cir., No. 99–1880)(challenge to June 1999 rule).

3 These rules are commonly referred to as the‘‘revocation’’ rules. Technically, however EPA didnot revoke the 1-hour standard through theserulemakings. The 1-hour standard remains aneffective regulatory standard under EPA’sregulations. 40 CFR 50.9(a).

4 Sections 172(a) and 181(a) provide EPA withauthority to classify areas that are designatednonattainment and to set attainment dates for thoseareas. Section 172(a) applies generally to any newor revised NAAQS, while section 181(a) is specificto certain ozone nonattainment areas.

5 The court decided other issues raised by thepetitioners. These issues were not raised onrehearing and are not relevant here.

6 The full court voted 5–4 in favor of rehearingwith two judges not participating. Since a majorityvote of the active members of the court is neededto grant rehearing, the request for rehearing wasdenied.

7 The American Lung Association and theCommonwealth of Massachusetts and State of NewJersey also filed petitions for certiorari. In addition,groups led by the American Trucking Associationsand Appalachian Power Company filed conditionalcross petitions for certiorari.

8 The court also granted the industry crosspetitions regarding the consideration of costs insetting NAAQS on May 30, 2000.

On June 5, 1998 (63 FR 31014), July22, 1998 (63 FR 39432), and June 9,1999 (64 FR 30911), in accordance with40 CFR 50.9(b), we issued final rules formany areas that were attaining the 1-hour standard, finding that the 1-hourozone standard no longer applied tothese areas. 2 At that time, we amendedthe Code of Federal Regulations (CFR) toremove the designations andclassifications that had applied to thoseareas for the 1-hour standard undersections 107, 172 and 181 of the CAA. 3

On May 14, 1999, the Court ofAppeals for the District of ColumbiaCircuit (D.C. Circuit) issued an opinionin the cases challenging EPA’s revisedozone and particulate matter standards.ATA v. EPA, 175 F.3d 1027 (D.C. Cir.,1999). The court questioned theconstitutionality of the CAA authority toreview and revise NAAQS, as applied inEPA’s revision to the ozone andparticulate matter NAAQS. The Courtstopped short of finding the statutorygrant of authority unconstitutional,instead providing EPA with anopportunity to articulate a determinateprinciple for revising the ozone andparticulate matter NAAQS under thestatute. 175 F.3d at 1034–40. The courtalso addressed EPA’s authority toclassify areas and to set attainment datesfor a revised ozone standard. 175 F.3dat 1034–40. Based on language insections 172(a) and 181(a) of the CAA,the court concluded that EPA couldonly classify and set attainment datesfor areas for purposes of any ozoneNAAQS under the provisions of section181(a) of the CAA, and that EPA couldnot enforce an ozone NAAQS morequickly than contemplated under theprovisions triggered by classificationsunder section 181(a) nor could EPAenforce an ozone standard, such as the8-hour standard, that was more stringentthan the 1-hour standard. 4 175 F.3d at1049–50. The court also held that EPAmust consider the beneficial effects oftropospheric ozone in protecting againstthe harmful effects of ultraviolet rays(UV–B). 175 F.3d at 1051–53. The court

remanded, but did not vacate, the 8-hour standard on the basis that it wouldnot ‘‘engender costly complianceactivity’’ in light of the court’s decision‘‘that it cannot be enforced by virtue ofCAA § 181(a).’’ 175 F.3d at 1057. TheEPA filed a petition for rehearing withrespect to these three aspects of thecourt’s decision. 5

On October 25, 1999, EPA publishedthe preamble to the proposed rule,‘‘Rescinding Findings That the 1-HourOzone Standard No Longer Applies inCertain Areas,’’ (64 FR 57424), notingthat the proposed regulatory languagefor part 81 would be published shortly.On November 5, 1999, EPA publishedthe proposed regulatory language forpart 81 (64 FR 60477). As proposed, the1-hour ozone standard would bereinstated in areas where it hadpreviously been revoked and theassociated designations andclassifications that previously appliedin such areas with respect to the 1-hourNAAQS also would be reinstated. Intoday’s final rule, EPA is taking finalaction to reinstate the area designationsand classifications that applied prior torevocation. Throughout this final ruleall references to reinstating designationsrefer to reinstating both designationsand classifications as well. In addition,EPA proposed to amend 40 CFR 50.9(b)to provide by rule that the 1-hour ozonestandard would continue to apply in allareas notwithstanding promulgation ofthe 8-hour standard, and that after the8-hour standard has become fullyenforceable under part D of title I of theCAA and subject to no further legalchallenge, the 1-hour standard set forthin section 50.9(a) would no longer applyto an area once EPA determines that thearea has air quality meeting the 1-hourstandard.

On October 29, 1999, the D.C. Circuitissued an opinion addressing EPA’spetition for rehearing. ATA v. EPA, 195F.3d 4 (D.C. Cir. 1999). The three-judgepanel that decided the case grantedrehearing on limited issues regardingEPA’s ability to implement a revisedozone standard. Both the panel and thefull court denied all other aspects ofEPA’s petition for rehearing.6 Withrespect to EPA’s authority to implementa revised 8-hour standard, the courtmodified its initial decision to providethat EPA may enforce a revised ozoneNAAQS only in conformity with the

control requirements triggered by aclassification under section 181(a)—i.e.,the provisions in subpart 2 of part D oftitle I of the CAA. 195 F.3d at 8. JudgeTatel filed a separate opinion, holdingthat the court should have deferred toEPA’s reasonable interpretation of theimplementation scheme for the revisedNAAQS, but concurring in themajority’s decision because it ‘‘leavesopen the possibility that EPA canenforce the new ozone NAAQS withoutconflicting with subpart 2’sclassifications and attainment dates.’’195 F.3d at 11.

At the request of commenters, onDecember 8, 1999, EPA published anotice in the Federal Register (64 FR68659) to reopen the comment periodfor the proposed rulemaking fromDecember 1, 1999 until January 3, 2000,thus affording the public a total of 60days to comment on the proposedreinstatement action.

On January 27, 2000, EPA filed apetition with the Supreme Court,seeking review of the court of appealsdecision regarding the constitutionalityof the provisions of the CAA for settingNAAQS and the court’s decisionregarding implementation of a revisedozone NAAQS. Other parties alsosought review by the Supreme Court.7The court granted EPA’s petition onMay 22, 2000.8

II. In Summary, What Action Is EPAFinalizing Today?

Today, we are taking final action torescind the findings that the 1-hourstandard no longer applies in thoseareas where the Agency had previouslydetermined that the 1-hour standard hadbeen attained. As a result, the 1-hourstandard will again become applicablein nearly 3,000 counties.

Where the 1-hour ozone standardagain becomes applicable as a result ofthis rulemaking, the attainment andnonattainment designations andclassifications applicable to such areasprior to the determination ofinapplicability will again apply. Thedesignations are inextricably linked tothe applicability of the standard andwere removed solely because thestandard no longer applied. See e.g.,Interim Implementation PolicyStatement, 61 FR 65752, 65754 (Dec. 13,1996) (‘‘the designations would remain



9 The EPA notes that in the proposal for thisaction, EPA proposed to make the finalreinstatement effective after 90 days for all areas,and specifically requested comment on this issue.Certain commenters requested a longer delay in theeffective date of the rule, and EPA has agreed thatfor areas with clean data that were previouslydesignated nonattainment a longer period would beappropriate. However, ‘‘effective date’’ is a term of

art relating to when rules published in the FederalRegister will be incorporated in the Code of FederalRegulations, and Office of Federal Registerrequirements do not allow varying effective datesfor entries in a table. Therefore, this action as awhole will become effective for all areas 90 daysafter publication. However, EPA will use the term‘‘applicability date’’ in the rule to describe the dateon which the reinstatement of the 1-hour standardwill begin to apply to an area. That date willgenerally be 180 days after publication for thoseareas with clean data previously designatednonattainment, as listed in Table 1 of the preamble.In addition, if States are able to submitredesignation requests and EPA is able to processsuch requests to the point of final action prior to180 days from publication, the final actionapproving the redesignation may provide that theapplicability date of the reinstatement will be thesame date as the effective date of the redesignationapproval, so that the redesignations may take effectin a timely manner.

in effect so long as the current 1-hourozone NAAQS remains in effect’’).Thus, since the only basis for removingthe designations was the inapplicabilityof the 1-hour standard, areadesignations for the standard must alsobe reinstated upon reinstatement of the1-hour standard.

Given that the previous designationsand classifications of these areas werebased upon the 1-hour ozone standard,which will again apply as a result of thisreinstatement action, EPA is amendingthe tables in part 81 of the CFR toidentify the designation andclassification of the area that appliedprior to EPA’s determinations that the 1-hour standard no longer applied. Theregulatory language located at the end ofthis final rule amends the ozone tablesin 40 CFR part 81 for each State andprovides a list of the areas affected bythis rule. A copy of these tables mayalso be viewed at the following Internetwebsite address: http://www.epa.gov/ttn/oarpg. In addition, the areas areidentified by air quality designations inthe docket for this rulemaking at DocketNo. A–99–22.

The EPA’s regulation, 40 CFR 50.9(b),provides that the 1-hour ozone standardwould no longer apply once EPAdetermined that an area attained thatstandard. Today’s action revises section50.9(b) to indicate that the 1-hourstandard remains applicable to all areasnotwithstanding the promulgation of the8-hour standard. Furthermore, today’saction establishes that after the 8-hourstandard has become fully enforceableunder part D of title I of the CAA andsubject to no further legal challenge, the1-hour standard set forth in section50.9(a) will no longer apply to an areaonce EPA determines that the area hasair quality meeting the 1-hour standard.

In light of many areas’ needs toquickly develop additional StateImplementation Plan (SIP) programs inresponse to the actions EPA is finalizingtoday, the actions finalized today willbecome effective 90 days after today’spublication for most areas. However, forareas that were designatednonattainment prior to revocation butthat currently have clean air quality datasufficient to support a redesignation toattainment, actions will not generallybecome applicable until 180 days aftertoday’s publication.9 This additional

time will allow areas to submitredesignation requests and, if they doso, for EPA to take appropriaterulemaking action on such requestsprior to the applicability date of thisrule for the area.

III. What Major Comments WereSubmitted on the Proposed Rule andWhat Are EPA’s Responses to SuchComments?

In our October 25, 1999 proposal, wesolicited comment on whether EPAshould rescind findings that the 1-hourozone standard no longer applies incertain areas, and if EPA acted torescind the 1-hour ozone standard, whatthe effects of a rescission would be. Insection IV of the proposal, EPAspecifically requested comment on theeffect of the rescission for five types ofareas: (1) Areas designated as attainmentwith no violation since revocation; (2)areas designated attainment (withoutmaintenance plans) with violationssince revocation; (3) areas designatedattainment (with maintenance plans)with violations since revocation; (4)areas designated nonattainment with noviolations since revocation; and (5)areas designated nonattainment withviolations since revocation. Also, theAgency requested comment on theprogrammatic effects of reinstatement,such as the applicability of new sourcereview (NSR) and conformity, as well ashow to deal with sanction and FederalImplementation Plan (FIP) clocks thatwere in effect at the time of therevocations. A total of 72 commentletters were received on the proposal.Most of the commenters generallysupported reinstating the 1-hourstandard; however, they voicedindividual preferences as to how EPAshould proceed to carry out this actionwith respect to designations, planningobligations and timing. For each of therelevant issues, the following discussionsummarizes EPA’s proposed action,

explains the approach EPA is adoptingin this final rule and responds to themajor comments received. Allcomments are addressed in the separateResponse to Comments Documentlocated in the docket.

A. Reinstatement of the Applicability ofthe 1-Hour Ozone Standard and theDesignation and Classification ThatExisted for Each Area at the Time EPADetermined the Standard No LongerApplied

The EPA generally proposed toreinstate the applicability of the 1-hourstandard in all areas for which EPA hadtaken action determining that thestandard no longer applied. In addition,EPA proposed that the designation andclassification for each such area wouldalso be reinstated. The EPA proposed torestore areas to the same position theywere in at the time EPA determined thatthe 1-hour standard no longer applied,i.e., that the designation andclassification that applied at the timethe 1-hour standard was revoked for anarea would once again apply uponreinstatement.

Comment: Several commentersbelieve that the Agency has no legalauthority to rescind findings that the 1-hour ozone standard no longer appliesin certain areas. Some commentersclaim that EPA cited no statutoryauthority for its action and that noneexists. At least one commenter contendsthat EPA’s regulation at 40 CFR 50.9(b)does not provide a basis for reinstatingthe 1-hour standard and challengesEPA’s statements that the basis forpromulgating 40 CFR 50.9(b) was theexistence of an enforceable 8-hourstandard.

Response: The EPA disagrees with thecommenters’ allegations that EPA hasno authority to rescind its findings thatthe 1-hour standard no longer applies incertain areas. The EPA made thosefindings in accordance with its rule at40 CFR 50.9(b), which provided that the1-hour standard would no longer applyonce an area attained that standard. TheEPA promulgated that regulation usingits general rulemaking authority undersection 301(a) of the CAA and thus hasauthority to revise that regulation (andto revise or repeal actions takenpursuant to that regulation) under thatsame authority. The changedcircumstances regarding the status ofthe 8-hour standard provide amplesupport for EPA to take this regulatoryaction under section 301(a).

Sections 108 and 109 of the CAAprovide for the promulgation or revisionof NAAQS on a periodic basis.However, those provisions are silentregarding how areas should transition



10 Section 172(e) provides guidance fortransitioning from a more stringent NAAQS for apollutant to a less stringent NAAQS for the samepollutant.

11 Subpart 2 of part D of title 1 provides detailedrequirements for certain ozone nonattainment areas.These provisions were enacted in 1990 in responseto the States’ continued failure to meet the ozonestandard. Rather than providing continuedflexibility and a one-size-fits-all approach, Congresscreated a tiered planning scheme that providedmore and tougher requirements for areas withsignificant ozone problems, but also provided moretime for these areas to meet the standards.

12 The fact that EPA’s regulation at 40 CFR 50.9(b)does not reference the 8-hour standard is notcontrolling for determining the underlying basis forEPA’s promulgation of that regulation. The fact that50.9(b) was promulgated simultaneous with the 8-hour standard and placed in the subchapter of theCFR governing NAAQS is sufficient evidence that§ 50.9(b) was premised on the existence of the 8-hour ozone standard. Furthermore, it is clear fromthe preamble that EPA believed that the 8-hourstandard would be enforceable, (62 FR 38856, July18, 1997).

from implementation of one NAAQS fora pollutant to a revised, more stringentNAAQS for the same pollutant.10

Where, as in the rule promulgating therevised 8-hour NAAQS, EPA determinesnot to retain the pre-existing standard asan independent NAAQS, EPA mustdetermine how areas should transitionaway from the pre-existing NAAQS.Since the CAA does not include specificprovisions addressing this transition,EPA relied on its general rulemakingauthority under section 301(a) of theCAA. See 62 FR 38894, July 18, 1997.Section 301(a) provides that the Agencyhas authority ‘‘to prescribe suchregulations as are necessary to carryout’’ its functions under the CAA. Ingeneral, the statutory authority forpromulgating a regulation also providesauthority for an Agency to revise thatregulation. The EPA is relying on itsgeneral rulemaking authority undersection 301(a) to rescind the findingsthat the 1-hour standard no longerapplies.

The present circumstances provideample support for EPA to take thisaction rescinding its earlierdeterminations. The EPA promulgated40 CFR 50.9(b) based on the existenceof an implementable 8-hour standard. Inpromulgating a revised 8-hour standard,EPA determined that it did not need toretain a separate 1-hour standard inorder to protect the public health withan adequate margin of safety and toprotect public welfare (62 FR 38863,July 18, 1997). Thus, EPA needed toconsider how to transition away fromthe existing 1-hour standard to therevised 8-hour standard. See e.g.,Proposed Interim ImplementationPolicy, (61 FR 65752, December 13,1996). In the final rule promulgating therevised 8-hour standard, EPA concludedthat Congress intended areas to remainsubject to the planning requirements ofsubpart 2 11 of the CAA for as long asthey continued to have air quality notmeeting the 1-hour standard. In order tofacilitate the continued applicability ofsubpart 2 to areas that had not yet metthat standard, EPA determined to delayremoval of the 1-hour standard from itsregulations by promulgating 40 CFR

50.9(b). It is clear from the context of therule and the statements in the preambleto the final 8-hour NAAQS rule that thedecision to find that the 1-hour standardno longer applied was based on theexistence of an enforceable 8-hourstandard that was protective of publichealth and welfare, such that the 1-hourstandard would no longer be necessaryto protect public health and welfare. (62FR 38873, July 18, 1997.)

However, because the court decisionhas raised doubts about theenforceability of the 8-hour standardand EPA’s ability to implement thestandard fully at this time, the basis forthe regulation revoking the applicabilityof the 1-hour standard in certain areasno longer exists. Contrary to what EPAbelieved would occur at the time itpromulgated 40 CFR 50.9(b), generallyareas are not currently moving forwardto implement the 8-hour standard due tothe uncertainty created by the litigationover the ozone NAAQS. Thus, EPAbelieves that it is necessary at this timeto retain the 1-hour standard in all areasto protect public health and welfare atleast until the status of the 8-hourstandard and any issues concerning itsenforceability have been fullyresolved.12

Comment: Some commenters believethat the proposed action to reinstate the1-hour ozone standard constitutespromulgation of a new or revisedNAAQS under section 109 of the CAAand that the action is therefore subjectto a public hearing under section 307(d).Other commenters contend that EPAmust or should vacate the 8-hourstandard before EPA can reinstate theapplicability of the 1-hour standard.These and other commenters contendthat section 109 contemplates only asingle air quality standard for aparticular pollutant in any given areaand, therefore, object to having dualstandards apply. They also claim thatthe existence of two ozone standards isconfusing.

Response: The EPA does not believethat the action to reinstate the 1-hourstandard constitutes the promulgation ofa new or revised NAAQS under section109 of the CAA. The 1-hour standardEPA is reinstating today is the same 1-hour standard that has been in existence

since its original promulgation onFebruary 8, 1979 and that continues tobe a part of EPA’s regulations at 40 CFR50.10, (44 FR 8202). The EPA is notrevising that standard in any way. TheEPA is merely reinstating theapplicability of that standard in certainareas. Unlike a regulatory actionpromulgating a new or revised NAAQS,this rulemaking is not concerned withselecting the appropriate level or formof ozone standards requisite to protectpublic health and welfare. Theparticular processes specified insections 108 and 109, requiring thedevelopment of detailed scientificassessments and consultation withscience advisory boards, are notimplicated by this action. The EPAundertook those processes when itpromulgated the 1-hour standard in1979. This action does not purport torevise or re-promulgate that standard; itonly specifies the applicability of theexisting 1-hour standard, which isspecified in section 50.10, to certainareas.

Because this action rescinding aprevious regulatory determination andrevising the regulation governing thetransition from the 1-hour to a revised8-hour NAAQS does not constituteeither an amendment or revision toeither the 1-hour or the 8-hour ozoneNAAQS, EPA disagrees with thecommenters that the proceduralprovisions in section 307(d) aretriggered by section 307(d)(1)(A)(requiring compliance with section307(d) for all rules promulgating orrevising any NAAQS). Since theadministrative requirements of section307(d) do not apply, EPA has compliedwith the public notice and commentprocess specified under theAdministrative Procedure Act, 5 U.S.C.553, which does not require the Agencyto hold a public hearing.

Nor does EPA agree that the properapproach is to vacate the 8-hourstandard. In the ATA decision, the D.C.Circuit did not dispute the public-healthbasis for the NAAQS and did not vacatethe 8-hour standard. The EPA sees noreason to take such an action on its own.The EPA has filed with the SupremeCourt a petition for review of the D.C.Circuit’s decision. The EPA sees noneed to vacate the 8-hour standard forthe purpose of revising the transitionscheme from the 1-hour standard to the8-hour standard. Because the CAA doesnot provide how EPA must transitionfrom one standard for a pollutant to arevised, more stringent standard for thatsame pollutant, EPA continues tobelieve it has authority to establish andto revise the appropriate transitionscheme. Due to the uncertainty created



13 Other commenters, without referencing anyspecific statutory authority, also claim that EPAshould use current air quality data to designateareas.

14 In revoking the standard, EPA did notredesignate areas pursuant to section 107 and didnot require areas to meet the redesignationrequirements of section 107(d)(3)(E), such asdevelopment of a maintenance plan. In fact, EPAhas been challenged on two of the revocation rulesfor not following, and not requiring States to follow,redesignation procedures. Environmental DefenseFund v. EPA, (D.C. Cir., No. 98–1363); AppalachianMountain Club v. EPA, (1st Cir., No. 99–1880).

15 In addition to EPA, two other parties haverequested that the Supreme Court review portionsof the D.C. Circuit’s decision regarding the ozoneand particulate matter NAAQS. Other parties haveopposed Supreme Court review of theimplementation issues. In their papers before theCourt, several of these parties have suggested thatEPA is barred from enforcing the more stringent 8-hour NAAQS, while others raise concerns that theCourt’s opinion is unclear regarding theenforceability of the 8-hour standard.

by the court’s opinion, EPA believes itis a reasonable exercise of its authorityto revise the transition scheme byreinstating the applicability of the 1-hour standard and the associateddesignations and classifications. Forthese reasons, EPA does not agree thatit must vacate the 8-hour standard inorder to reinstate the applicability of the1-hour standard.

To the extent the commenters areconcerned about the existence of twoNAAQS for the same pollutant, EPAmade the decision in the 1997 NAAQSrulemaking by determining to retain the1-hour standard until areas met thatstandard. As provided above, EPA is nottaking action to revise or promulgate arevised NAAQS in this rule and is notre-opening its previous decision that thestatute allows the applicability of morethan one NAAQS for a pollutant, suchas ozone.

Comment: Some commenters claimthat EPA cannot restore the designationfor areas except through one of thedesignation processes provided undersection 107 of the CAA. Somecommenters contend that EPA shouldtreat these designations as initialdesignations under section 107(d)(1)and that EPA should provide time forGovernors to make recommendationsbefore EPA may designate areas. Othercommenters contend that EPA must usethe redesignation provisions undersection 107(d)(3). Under that provision,they contend, EPA must notify theGovernor first of its intent to redesignateand then must rely on current airquality data.13 Some of thesecommenters agree with EPA that thedesignation in place at the time EPArevoked the standard should be put backinto place. Other commenters suggestthat EPA cannot consider air qualitydata from the period when the standarddid not apply and that EPA shouldreinstate designations based on airquality data from the period after thestandard is reinstated.

Response: The EPA does not believeit needs to go through the procedures ofsection 107 of the CAA to reestablishthe designations that were in place priorto revocation of the 1-hour standard. Inthis action, EPA is reversing itsrevocation of the standard because therecent court decision has called intoquestion the underlying bases for thataction. In the revocation action, EPA didnot change an area’s designation for the1-hour standard, but determined thatsince the 1-hour standard no longer

applied to an area, the designationassociated with that standard also nolonger applied.14

As explained above, EPA’s actiontoday is not the promulgation of new orrevised NAAQS. Therefore, the initialdesignation provisions in section107(d)(1), which apply only uponpromulgation of a new or revisedNAAQS, do not apply.

Nor is EPA redesignating areas forpurposes of the 1-hour standard. Theseareas currently do not have in place adesignation for the 1-hour standard. Theprovisions in section 107(d)(3), whichapply only to redesignations fromattainment or unclassifiable tononattainment or from nonattainment toattainment simply do not apply where,as here, there is not a currentdesignation in place for a standard.

The EPA’s primary action throughthis action is to reinstate theapplicability of the 1-hour standard. Atthe time EPA promulgated 40 CFR50.9(b), it determined that thedesignations should follow theapplicability of the 1-hour standard andthat the current designation wasinextricably linked with theapplicability of the 1-hour standard.Therefore, just as EPA determined thatan area’s designation no longer appliedonce the 1-hour standard on which itwas based no longer applied, thereinstatement of the 1-hour standardnecessarily brings back the applicabilityof the designation. Similarly, as EPArelied on its general rulemakingauthority to revoke the standard andthus the area’s designation, EPA isrelying on that same authority to reversethe action taken in its earlier rule. Onceareas have a designation for the 1-hourstandard in place, EPA may redesignatethose areas if they meet therequirements of section 107(d)(3)(E). Asdiscussed in section III.F, below, EPAwill consider redesignating those areasthat have clean air quality data based onthe three most recent years of data andthat submit a redesignation requestmeeting the requirements of section107(d)(3)(E).

Finally, some commenters suggestthat EPA is prohibited from consideringair quality data that became availableafter EPA revoked the standard. TheEPA disagrees with this comment.Because EPA is reinstating the

designations that existed at the timeEPA revoked the standard, thisrulemaking does not reflect more recentair quality data. However, in futureactions to redesignate areas, EPAintends to consider all relevant airquality data including data that becameavailable during the revocation. To theextent these commenters continue tohave concerns about this issue, they canraise them in any future rulemakingaction EPA may take to redesignate anarea on the basis of that data.

Comment: A few commenters statedthat we cannot rely on the argument thatthe 8-hour standard cannot be enforcedas the basis for revocation since this isnot supported by the Court’s October 29,1999, decision on rehearing. In theOctober 29 opinion, the Court retractedits earlier conclusion that ‘‘the 8-hourstandard cannot be enforced,’’ providinginstead that the 8-hour standard ‘‘can beenforced only in conformity withsubpart 2’’ of part D of title I of the CAA.Compare 175 F.3d at 1057 with 195 F.3dat 10. Some commenters also suggestthat it is too late for us to reconsider therevocations and to reinstate theapplicability of the 1-hour standard.Most commenters, however, supportreinstatement on the basis of continueduncertainty regarding the 8-hourstandard.

Response: The EPA believes that theuncertainty engendered by the litigationsurrounding the 8-hour standardjustifies reinstating the 1-hour standard.It is true, that on rehearing, the Courtrevised its original opinion to indicatethat EPA can enforce the 8-hourstandard in conformity with subpart 2 ofthe CAA. However, in that samesentence, the Court provided that it wasremanding the 8-hour standard. TheCourt did not vacate the 8-hour standardbecause ‘‘the parties have not shownthat the standard is likely to engendercostly compliance activities.’’ As thepetitions for certiorari before theSupreme Court demonstrate, therecontinues to be uncertainty regardingwhen the standard could beimplemented in light of the ongoinglitigation.15 Because of the continuinglitigation and the differing views of themany parties to the litigation, EPA is notcurrently taking any action that could beconstrued as inconsistent with the



16 For example, EPA has stayed the applicabilityof its final regulatory determinations under section126 of the CAA to the extent they were based onthe 8-hour NAAQS. (65 FR 2674, January 17, 2000).Similarly, EPA recently proposed to stay the 8-hourbasis of its NOX SIP call rule, which calls on 22States and the District of Columbia to reduceemissions of nitrogen oxides that contribute toozone problems in other States. (65 FR 11024,March 1, 2000).

17 If the 8-hour standard promulgated in July 1997does not become enforceable because of Agencyaction taken in response to any unappealabledecision by the court in the ATA v. EPA litigation,then the second sentence of 40 CFR 50.9(b) wouldnot have any legal effect. As appropriate, EPA couldreconsider this regulation at the time it takes anyaction in response to an unappealable decision.

Court’s decision.16 In light of thecontinuing uncertainty regarding EPA’sauthority to implement the 8-hourstandard, EPA believes it is prudent toreinstate the 1-hour standard to ensurepublic health protection from ozone.

Contrary to the suggestions of somecommenters, EPA does not believe it istoo late to rescind the revocations of the1-hour standard. The commenter doesnot cite and EPA is unaware of anylimitation on when an Agency maychange a regulation based on newinformation. The EPA acted quickly inresponse to the uncertainty raised by theCourt’s decision, proposing action only5 months after the original decision bythe court. During that time, EPA wasassessing the impacts of the opinion onimplementation of the 8-hour standard,determining options for rehearing andappeal, and developing the proposedrule to rescind the revocations of the 1-hour standard. Based on requests for anextension of the comment period, EPAprovided a comment period of 60 dayson this action. Thus, EPA is acting in atimely fashion by issuing this ruleapproximately a year afer the courtissued its original decision.

Comment: A few commenterssuggested that EPA was proposing toreinstate the standard in too many areas.One set of commenters noted that EPA’sgoal of providing protection in areasnow violating the 1-hour standard couldbe accomplished by reinstating thestandard only in those areas that wereviolating the 1-hour standard. Othercommenters suggested that we notreinstate the 1-hour standard in Statesthat have adopted the 8-hour standardor where the most recent data for anarea indicate that it would be designatedattainment for the 8-hour standard.These commenters are concerned thatresources will be wasted on meeting the1-hour standard rather than the moreprotective 8-hour standard.

Response: The EPA determined that itis critical to have a fully enforceablestandard for ozone in each area of thecountry in order to protect the publichealth and welfare and to minimizepublic confusion. The EPA believes thatit is important to have a fully-implementable ozone standard in placein order to ensure adequate protectionof public health. A fully enforceable 1-hour standard will ensure that sufficient

control measures remain in place toprevent violations in areas attaining thestandard and to continue improvementsin air quality in areas not attaining thestandard. The options presented by thecommenters would not result in theapplicability of a fully-enforceableozone standard and thus could erodepublic health protection for peopleliving and working in areas that mightviolate the standard in coming ozoneseasons.

With respect to those commenters thatsuggest that EPA not reinstate thestandard in areas that have adopted the8-hour standard, EPA is concerned, inlight of the ATA decision, that it will beunable to enforce fully the 8-hourstandard in the short term. Without afully enforceable, Federal 8-hourstandard, EPA does not have the abilityto require States to implement an 8-hourstandard. This is true even in States thatmay have adopted the 8-hour standardas a State rule. Since State adoption ofthe 8-hour standard does not ensureimplementation and enforcement of thatstandard in conformity with Federalrequirements for clean air, EPA believesit is necessary to reinstate the 1-hourstandard in all areas pending resolutionof litigation over the 8-hour NAAQS.The EPA acknowledges that it may bemore efficient to concentrate resourceson planning to implement a moreprotective 8-hour standard, but EPAlacks the ability to require States to doso at this time. For these reasons, EPAbelieves that the existence of the 8-hourstandard does not provide the samecertainty of public health protection asdoes the 1-hour standard at this time.

Finally, with respect to the commentthat EPA not reinstate for areas that willbe designated attainment for the 8-hourstandard, EPA has not designated anyareas for the 8-hour standard. The Stateshave not recommended boundaries forpurposes of the 8-hour standard andEPA has not yet determined boundariesor designated any 8-hour areas. In fact,EPA guidance on the determination ofboundaries was issued only recently.(Boundary Guidance on Air QualityDesignations for the 8-Hour OzoneNational Ambient Air Quality Standards(NAAQS or Standard), March 28, 2000).The EPA has advised States to considerthe guidance and makerecommendations to EPA by June 30,2000. The EPA must then respond tothose recommendations and give States4 months comment on its response.Only after this process could EPA makefinal designations. Given the many stepsthat must occur before EPA promulgatesdesignations for the 8-hour standard,EPA believes it is far too early topresume precisely which areas would

be designated attainment for the 8-hourstandard.

B. Revision to 40 CFR 50.9(b) to ProvideThat EPA Will Again Determine the 1-Hour Ozone Standard No LongerApplies to an Area Once EPA’sAuthority to Implement and FullyEnforce the 8-Hour Standard Is NoLonger in Question

The EPA proposed to revise 40 CFR50.9(b) to provide that once the 8-hourozone standard is fully enforceable andno longer subject to legal challenge, the1-hour standard will no longer apply toan area if EPA determines that the areahas air quality meeting the 1-hourstandard.17 The EPA’s final rule adoptsthis position.

Comment: Some commenters disagreewith EPA’s proposed revision to§ 50.9(b). These commenters feel thatthe promulgation of an 8-hour standardshould not be the basis for revoking theapplicability of the 1-hour standard.Some of the commenters believe thatremoving the applicability of a NAAQSand associated control measures basedsolely on air quality is inconsistent withthe law and that we should considerboth the 1-hour and 8-hour ozonestandards. Some commenters believethat future revocations should not beallowed without first following theredesignation process as prescribed bythe CAA. Other commenters suggest thatonce the 8-hour ozone standard isenforceable, we should revoke the 1-hour standard everywhere regardless ofwhat the air quality is. Finally, onecommenter claims that EPA should notamend section 50.9(b) now since the 8-hour standard may never be enforceable.

Response: The EPA believes that ithas the authority upon issuance of anew or revised standard to determinethe continued validity of the pre-existing standard and when, if ever, itshould no longer apply. In the final rulepromulgating the 8-hour standard, EPAdetermined that the 1-hour standardwas no longer necessary to protectpublic health and welfare in light of therevised 8-hour standard, which Stateswould be required to implement andenforce. However, EPA also determinedthat Congress intended areas thatremained nonattainment for the 1-hourstandard to meet the requirements ofsubpart 2, until the 1-hour standard isattained. As EPA explained in the



18 EPA’s scheme for transitioning to the 8-hourozone standard is consistent with the Agency’sapproach in the one other case where itpromulgated a more stringent NAAQS revision. See52 FR 24672 (July 1, 1987). When EPA revised theparticulate matter standard to change the indicatorfrom total suspended particulates (TSP) toparticulate matter with a diameter of 10 microns orless (PM–10), it retained the TSP designations fora limited purpose because the statutory limitationsfor certain areas under the Prevention of SignificantDeterioration (PSD) program were linked to TSPdesignations. See CAA section 163. Congresssubsequently codified EPA’s decision in section107(d)(4)(B) of the CAA. Similarly, EPA here isretaining the 1-hour standard and associateddesignations for purposes of continued applicationof subpart 2 of the CAA, until the purpose ofsubpart 2—attainment of the 1-hour standard—ismet.

19 Furthermore, no party in the ATA casechallenged EPA’s promulgation of 40 CFR 50.9(b)and the court did not address this regulatoryprovision in either its May 14, 1999 or its October29, 1999 decisions.

preamble to the NAAQS rule, section109 of the CAA clearly authorizes EPAto promulgate revisions to a standard,which necessarily includes theauthority to revoke previous standardsthat have been revised (62 FR 38857,July 18, 1997). On the other hand,subpart 2 of the CAA sets out numerousrequirements specifically applicable toareas not attaining the 1-hour ozonestandard. To accommodate both of theseprovisions, EPA concluded that afterpromulgation of the 8-hour standard,subpart 2 must continue to apply as amatter of law in each area until the 1-hour standard is attained (62 FR 38873).Thus, to facilitate continuedapplicability of the subpart 2requirements, EPA established atransition scheme in 40 CFR section50.9(b) that provided the 1-hourstandard would continue to apply untilan area had air quality meeting the 1-hour standard.

The EPA does not agree that in orderto determine a pre-existing standard nolonger applies, EPA must require areasto meet the requirements forredesignation and formally redesignatean area from nonattainment toattainment under section 107(d)(3). As ageneral matter, Congress has notspecified any procedure for determiningthat a pre-existing NAAQS no longerapplies once EPA promulgates a revisedstandard. Moreover, although Congressgave some guidance on how totransition to a less stringent NAAQS,see CAA section 172(e), it did notprovide clear guidance on how totransition to a more stringent NAAQS.The EPA believes that in determininghow to transition to a revised NAAQS,it must make common-sense decisions,considering the intent of Congress inlight of the statutory scheme, includinghow best to ensure public healthprotection without imposing undulyburdensome requirements on States andsources.18

With respect to the transition from the1-hour standard to the 8-hour standard,

EPA determined that Congress intendedareas to remain subject to the 1-hourstandard until such time as thatstandard is met. Since all areas of thecountry were subject to the revised,more stringent 8-hour standard, EPAdetermined that it did not make senseto require areas that had met the 1-hourstandard but remained designatednonattainment to complete amaintenance plan since generally theseareas would be required to develop anattainment plan for the more stringent 8-hour standard. The EPA continues tobelieve that, if a fully enforceable 8-hourstandard were in effect, it would beunreasonable to require States todemonstrate that an area will maintainthe 1-hour standard for 10 years (witha later update for a subsequent 10 years)when these areas would be developingattainment plans and, ultimately,maintenance plans for the morestringent 8-hour standard.

This interpretation is consistent withthe approach Congress employed in theone area where the statute does addressrevocation of a prior standard. Section172(e) of the CAA provides that whereEPA relaxes a standard, it must requireall areas that have not yet attained themore stringent prior standard to providefor controls that are at least as stringentas those that applied to areas designatednonattainment of the prior standard.This provision both clarifies thatCongress intended EPA to revokestandards and associated controlrequirements in certain circumstanceswhere they have been revised, and thatan appropriate criterion for determiningwhen a prior standard should berevoked is whether or not an area hasattained that standard. Congress did not,however, require redesignation of areaswith development of maintenance plansprior to removal of control obligations.Rather, Congress required only thatcontrol measures continue to applyuntil an area has attained a priorstandard and implicitly allows forrevocation of the prior standard.

The EPA also disagrees with thecommenter who suggests that EPAshould not amend § 50.9(b) because ithas been struck down by the court andthat the 8-hour standard might never beenforceable. The EPA disagrees with theclaim that the court struck down 40 CFR50.9(b). The court did not vacate anyaspect of EPA’s July 1997 rulemaking,which included the promulgation ofsection 50.9(b).19 The EPA believes thatits proposed revision to section 50.9(b)

addresses the contingency that the 8-hour standard may never becomeenforceable. The EPA believes that it isbetter to promulgate revisions to section50.9(b) at this time so that interestedparties are aware of EPA’s plannedtransition approach if and when the 8-hour standard becomes fullyenforceable.

Finally, for the reasons explainedabove, EPA believes that subpart 2continues to apply as a matter of law toall areas that have not yet attained the1-hour standard. Therefore, EPA doesnot believe it has the authority todetermine the 1-hour standardinapplicable to any area that has not yetattained that standard, even after the 8-hour standard has become fullyenforceable.

C. Areas Designated as Attainment WithNo Violations Since Revocation

The EPA proposed that uponreinstatement of the standard, areasdesignated as attainment with noviolations after revocation would not besubject to any new planningrequirements under subpart 2 of theCAA, beyond continuing compliancewith any requirements in an approvedmaintenance plan. The EPA is adoptingthis position in today’s action.

Comment: Some commenters contendthat all areas designated as attainmentshould be treated on an equal basis. TheEPA should either require all attainmentareas to have maintenance plans,including the obligation to comply withconformity, or free all areas from themaintenance plan requirement.

Response: The EPA does not have theauthority to require all areas designatedas attainment either to have amaintenance plan or to relieve them ofthat obligation. The CAA specificallyprovides that areas seekingredesignation from nonattainment toattainment must develop and submitmaintenance plans. Upon redesignation,these areas are required to continue toimplement their maintenance plans,including complying with theconformity provisions. Areas that wereinitially designated as attainment afterthe 1990 CAA Amendments are notsubject to this requirement. In addition,section 176(c)(5)(B) of the CAA makesclear that areas with maintenance planscontinue to be subject to conformity andthat areas that have historically beendesignated as attainment are not subjectto conformity.

D. Areas Designated Attainment(Without Maintenance Plans) WithViolations Since Revocation

The EPA proposed to provide areasdesignated attainment without



20 For areas designated as nonattainment seekingredesignation to attainment, section 107(d)(3)(E)sets forth additional criteria that must be met beforeEPA may redesignate the area.

maintenance plans, that have hadviolations since revocation, a reasonabletime to come back into attainment priorto taking action to designate them asnonattainment. There are only fourareas which fall into this category:Berrien Co., MI; Hamilton Co., IN;Hamilton Co., TN; Rowan Co., NC.

Comment: Several commenters askedthat we define what is a ‘‘reasonabletime frame’’ to bring areas back intoattainment. Some commenters referencemeasures that States have already takento address ozone problems.

Response: The CAA does not mandatethat EPA redesignate areas fromattainment to nonattainment. Rather,section 107(d)(3)(A) provides thegeneral criteria that EPA may considerin determining whether to redesignatean area.20 In particular, EPA mayconsider air quality data, planning andcontrol considerations or any other air-quality related considerations.

The Agency commends areas for anyinitiatives they may have taken, such asvoluntary emission reduction programs,to help improve air quality. The EPAwill consider this information indetermining whether and when to moveforward with a redesignation tononattainment. States should work withthe appropriate EPA Regional Offices todetermine whether additional measuresare necessary to address a recentviolation.

To the extent additional measures areneeded, EPA believes that it isreasonable for States to adopt measuresto address any violations within 6–9months of the effective date of this finalaction. The EPA is recommending 6–9months as the presumptive period foraction, however, each State should workwith the relevant EPA Regional Office todevelop a strategy for specific areas.States have been on notice of EPA’splanned reinstatement of the standardand should have begun an analysis ofmeasures to address any violation. Inaddition, since reinstatement for theseareas will not be effective until 90 daysafter publication of this final action inthe Federal Register, this approach willallow States 9–12 months frompromulgation of this final rule to adoptany necessary measures and well over ayear from the time of EPA’s proposal toreinstate the standard. The EPA believesthat this period is comparable to the 1-year time period provided under section179(d) for States to adopt measuresbased on a finding that the State failedto attain the standard.

E. Areas Designated Attainment (WithMaintenance Plans) With ViolationsSince Revocation

For areas designated attainment withmaintenance plans and with violationssince revocation, EPA proposed that thecontingency measures in the area’sapproved SIP should be implemented toaddress any violations of the 1-hourozone standard. If a State had removedany contingency measures after EPAdetermined the 1-hour standard nolonger applied, EPA proposed the Stateshould place the contingency measureback into the SIP. There are seven areaswhich fall into this category: Charlotte-Gastonia, NC; Huntington-Ashland,WV–KY; Knoxville, TN; Nashville, TN;Portland-Vancouver Air QualityManagement Area, OR–WA; Richmond,VA; Sheboygan, WI.

Comment: Several commentersquestion whether it is appropriate torequire States to implement contingencymeasures and question whethercontingency measures will provide anyreal air quality benefits. They disagreethat automatic implementation of suchmeasures is the correct solution toaddressing the current air qualityproblem. Some commenters believe thatsince the 1-hour standard did not applyin the areas after revocation, the areascannot be considered to be violating the1-hour standard based on data from thattime; thus in their view, violations thatoccurred after revocation but prior toreinstatement cannot triggercontingency measures. Somecommenters argue that even if aviolation occurred during the period inwhich the standard was revoked, themost recent 3 years of air quality datashould have precedence. They state thatif those data indicate the area is notviolating the standard, the State shouldnot be required to implementcontingency measures.

In addition, some commenters wereconcerned that the schedule specified inthe SIPs for implementation ofcontingency measures is often triggeredas of the date of the violation. Thus,under these SIPs, some portion of theimplementation period may alreadyhave passed by the time thereinstatement becomes effective.

Other commenters claim that EPAshould use its authority under section110(k)(6) to place deleted contingencymeasures back into the SIP. Section110(k)(6) provides that EPA may reviseits prior approval removing thecontingency measures if it determinesthat the approval action was in error.

Response: Section 175A(d) of theCAA requires that a maintenance planinclude such contingency measures as

are necessary to promptly correct anyviolation of the NAAQS that occurs afterredesignation of the area. The EPAbelieves that areas designated asattainment that have maintenance plansin place and that have had violations ofthe NAAQS since revocation, arerequired by the CAA and by theirapproved SIPs to move forward toimplement contingency measures. Sincethe purpose of these measures is toprotect public health, EPA believes it isappropriate to require areas toimplement contingency measures toensure that future air quality will meetor be lower than the NAAQS.

The EPA has allowed States a greatdeal of flexibility with respect tocontingency measures. First, EPA hasallowed flexibility in terms of theselection and adoption of contingencymeasures for the maintenance plan. TheEPA does not require that contingencymeasures be fully adopted in order forthe maintenance plan to be approved.The maintenance plan need only ensurethat the contingency measures beadopted expeditiously once they aretriggered. (Procedures for ProcessingRequests to Redesignate Areas toAttainment, September 4, 1992, JohnCalcagni).

In addition, when an area violates thestandard, States have discretion inselecting which of the contingencymeasures in the approved maintenanceplan should be implemented. In thepast, EPA has allowed States tosubstitute and implement new, moreappropriate and effective contingencymeasures. (64 FR 28753 and 64 FR28757, May 27, 1999). The EPA wouldallow States with areas violating thestandard to do so here through the SIPprocess, if substitution of measureswould not unreasonably delay airquality benefits. Therefore, if, as at leastone commenter suggests, existing,approved contingency measures may nolonger be appropriate or effective, theState may seek a substitution. However,the fact that existing contingencymeasures may not be effective orappropriate does not support a decisionnot to require implementation ofcontingency measures to address the airquality problem.

Finally, although EPA has indicatedthat it would provide a reasonableperiod of time for violating attainmentareas without maintenance plans tocorrect their air quality problem beforedesignating them to nonattainment, EPAdoes not believe it has the ability todelay the triggering of the States’obligation to select and adoptcontingency measures for areas withmaintenance plans that are experiencingviolations. The CAA contemplates that



contingency measures will beimplemented ‘‘promptly’’ in such areas.In addition, the terms of themaintenance plans themselves requireadoption and implementation ofcontingency measures upon violations.Thus, the CAA requires areas to adoptappropriate contingency measures onceviolations occur. States may submit SIPrevisions to substitute appropriatemeasures at any time.

The EPA disagrees that violations arenot valid if they occurred during theperiod when the 1-hour standard didnot apply for an area. The fact that anair quality standard does not applyduring a period of time does notinvalidate air quality data gathered atthat time or invalidate the exceedancesor violations demonstrated by that data.In fact, the statutory period for initialdesignations belies that interpretation.Under section 107(d)(1), Governorsmust recommend designations within 1-year of promulgation of a standard andEPA must designate areas within 2 yearsof promulgation. For standards that aremeasured over a period of longer than2 years, such as the 1-hour and 8-hourozone standards, EPA would necessarilybe required to consider monitoring datathat preceded promulgation of thestandard in making designations. Inaddition, the State and sources are notunreasonably disadvantaged. The EPAis not requiring that the time for Statesto implement contingency measuresruns from the time of the violation, butrather from the effective date of thereinstatement of the standard.

This approach is consistent with theapproach EPA is taking concerningtolling of applicable clocks forconformity obligations and sanctions.As EPA states elsewhere in this notice(sections III.I and III.J), EPA believesthat clocks related to the timing ofconformity determinations andsanctions should not be considered tohave run during the period that the 1-hour standard was not applicable to anarea. It would be unfair to areas to havesuch clocks expire during a time thatthe area was not subject to the planningobligations associated with the clocks.Thus, EPA has concluded that any suchclocks would be tolled during the timethe standard was not applicable. Whenthis rule becomes applicable, the clockwill begin to run again based onwhatever time remained when EPArevoked the standard for an area.Similarly, EPA believes that the duty toimplement contingency measuresshould be triggered on the effective dateof this reinstatement action rather thanthe date of any past violation.

If an area has a SIP in which thetiming for contingency measures is

triggered on the date of the violation,EPA believes that it would beappropriate to interpret the violation asoccurring on the effective date of thereinstatement. If States still remainconcerned about the approved languagein existing SIPS regarding the timing fortriggering contingency measures, theyshould work with the relevant EPARegional Office to determine anappropriate manner to address the issue.Since the 1-hour standard was not ineffect for the area during the revocationperiod, EPA does not believe that thearea should be subject to a shorter timethan contemplated in the State’sadoption and EPA’s approval of the SIP.

With respect to commenters thatclaim that an area may have had aviolation (during 1996–1998) and onceagain is attaining (during 1997–1999),EPA believes that such areas shouldwork with the relevant EPA RegionalOffice to determine an appropriatecourse of action. If there are additionalcontrol measures that applied during1999, but did not apply during theperiod of the violation, it may not benecessary to implement furthercontingency measures at this time.

The EPA allowed States to removecontingency measures from approvedSIPs where they were linked to the 1-hour standard or air quality ozoneconcentrations and EPA had takenaction to determine that the 1-hourstandard no longer applied. See‘‘Guidance for Implementing the 1-HourOzone and Pre-Existing PM10 NAAQS,’’from Richard D. Wilson, ActingAssistant Administrator for Air andRadiation, December 29, 1997. The EPAbelieved that such revisions would beconsistent with section 110(l) of theCAA since EPA was determining thatthe 1-hour standard no longer appliedand, therefore, removal of thecontingency measures would notinterfere with any applicablerequirement concerning attainment andreasonable progress, or any otherapplicable requirement of the CAA. Id.

Because EPA believes it is nowappropriate and necessary to reinstatethe 1-hour standard, EPA believes it isno longer appropriate for States not tohave those contingency measures in theapproved SIP. States will need to moveforward to put contingency measuresback into the SIP. The EPA believes thatStates should have some discretion inselecting these contingency measuresconsidering what measures would beappropriate, and adopting suchmeasures, as necessary. Thus, at thistime, EPA is not moving forward to usesection 110(k)(6) to retract its earlierapproval of SIP revisions removingcontingency measures. Since EPA is not

now proposing to move forward undersection 110(k)(6), EPA is not addressingwhether that provision provides thelegal authority to take the actionsuggested by the commenters.

F. Areas Designated NonattainmentWith No Violations Since Revocation

For areas designated nonattainmentwith no violations since the standardwas revoked in these areas, EPAproposed that the nonattainmentdesignation would again apply, butrecommended that the State submit aredesignation request that meets therequirements of section 107(d)(3)(E). Inaddition, EPA noted that its May 10,1995, ‘‘Clean Data Policy’’ couldprovide relief from some subpart 2measures for these areas as long as theycontinued to have clean data. However,other subpart 2 requirements wouldapply unless and until an area wasredesignated to attainment. There are 45areas which fall into this category. Thefollowing table (Table I) lists the areasin this category:

21 Section 107(d)(3)(E) provides that EPA may notredesignate an area from nonattainment toattainment unless EPA: (1) determines that the areahas attained the relevant NAAQS; (2) has fullyapproved the area’s SIP; (3) determines that theimprovement in air quality is due to permanent andenforceable reductions in emissions; (4) has fullyapproved a maintenance plan for the area; and (5)has determined that the State has met all of theapplicable SIP planning requirements.

were opposed to reinstating priordesignations and classifications,particularly in the case of areas thatwere designated nonattainment at thetime of the revocation and that haveremained clean. They want EPA toconsider current monitoring data as thebasis of an area’s designation. Thesecommenters claim that EPA’s proposedapproach creates inequities among thevarious types of areas where thestandard would be reinstated. Forexample, they point to areas that will bedesignated attainment but that areviolating the 1-hour standard. Thecommenters contend that it isinequitable that those areas will not besubject to subpart 2 controlrequirements, including new sourcereview and conformity, but that certainnonattainment areas that have remainedclean since revocation will be. Onecommenter did not seem to object tothis approach, but recommended thatEPA approve pending redesignationrequests within 1 to 3 months of thefinal reinstatement.

Other commenters supported EPA’sproposal to restore the designations andclassifications that applied at the time ofthe revocation action. Several of thesecommenters claimed that EPA shouldnot or could not consider violations thatoccurred while the standard was notapplicable. Others recommended thatEPA designate as nonattainment allareas that have current violations of the1-hour standard.

Specifically, some commentersrequest that EPA now designate asattainment areas that were designated asnonattainment and that have never beenapproved for redesignation inaccordance with the criteria in section107(d)(3)(E). Thus, the commentersrequest EPA to rely on its revocationaction as a justification for avoidingthose requirements.

Response: As provided in sectionIII.A, above, in today’s action EPA isonly reversing its earlier determinationthat the 1-hour standard no longerapplies in these and other areas.Therefore, EPA is not consideringcurrent air quality data in establishingdesignations under this action as EPAwould do when establishing initialdesignations for areas under section107(d)(1) or redesignating areas undersection 107(d)(3). In promulgating 40CFR 50.9(b), EPA determined that thedesignations and classifications werelinked to the applicability of the 1-hourstandard. On that basis, in applyingsection 50.9(b), EPA removed not justthe applicability of the 1-hour standard,but also the associated designation andclassification for the 1-hour standard.Because EPA is rescinding its priorfindings concerning the applicability ofthe 1-hour standard, the designationsand classifications that accompaniedthat standard at the time of revocationcome back into place with the standard.

The EPA disagrees with thecommenters as a matter of law andpolicy. It is clear from the CAA, asamended in 1990, that Congressintended areas to meet specific criteriafor redesignation with respect to anexisting, applicable NAAQS. Asdiscussed above in section III.A & B,EPA believes it was appropriate totransition from the 1-hour ozonestandard to the 8-hour ozone NAAQS byrequiring only that areas attain the 1-hour standard—one of the five criteria 21

for redesignation. However, EPAbelieves it would circumventCongressional intent to reinstate the 1-hour standard because of theuncertainty surrounding the 8-hourstandard and permit areas effectively tobe redesignated from nonattainment toattainment without meeting the otherfour redesignation criteria. The EPAdoes not believe that it can rely on itsrule determining the 1-hour standard no

longer applies, the basis for which hasbeen undermined by the ATA decision,as support for sidestepping theredesignation criteria.

Moreover, because EPA cannot besure how long it will take to resolve theissues surrounding the 8-hour standard,EPA believes that it is important toensure that areas will maintain the 1-hour standard. The statutoryredesignation criteria are designed toaccomplish that goal. Thus, EPAbelieves it is essential that they be met.

However, EPA believes that it isappropriate to provide additional timeto nonattainment areas with clean airquality data since revocation in order tocomplete the redesignation process.Therefore, EPA is taking final actiontoday to delay the applicability date ofthe final rule for up to 180 days for areasthat were designated nonattainment atthe time of revocation and continue tohave clean data, in order to allow Statesto submit redesignation requests andEPA time to act on them prior to theapplicability date. These areas areidentified in Table 1. In the proposedaction to reinstate the standard, EPArecommended that areas begin todevelop redesignation requests (orrevise, as necessary, any existingrequests) so that EPA could moveforward quickly to approve the requestsupon reinstatement. The EPAunderstands that some States are nowready, or close to being ready, to submitthese requests to EPA. If requests aresubmitted within the next 2 months,EPA believes it can complete action onthem before this rule becomesapplicable. The EPA will work withStates to ensure that review ofredesignation requests occursexpeditiously. In addition, if States areable to submit redesignation requestsand EPA is able to process such requeststo the point of final action prior to 180days from publication, the final actionapproving the redesignation mayprovide that the applicability date of thereinstatement will be the same date asthe effective date of the redesignationapproval, so that the redesignations willoccur simultaneously with thereinstatement.

Once EPA approves a redesignationrequest, an area would be subject to therequirements of the approvedmaintenance plans. Redesignation toattainment does not relieve an area of itsconformity obligations.

With respect to all of the areaspreviously designated nonattainmentwhich currently have clean air qualitydata, as listed in Table 1, EPAconcluded at the time of revocation thatthese areas had clean air quality data.These findings remain applicable unless



22 One court, in an unpublished opinion, upheldEPA’s interpretation of the redesignation provisionsof the CAA that an area must attain the standardand remain in attainment during the time that aredesignation request is pending in order to qualifyfor redesignation. Commonwealth of Kentucky, etal. v. US EPA, No. 96–4274 (6th Cir. Sept. 2, 1998).

23 One commenter suggests that we could do soas we did in revoking the standard. However, thatwas not a case of simply telling areas that they didnot need to submit maintenance plansnotwithstanding their nonattainment designation. Itwas a case of telling areas that they were no longersubject to any obligations with respect to the 1-hourstandard based on expected implementation of the8-hour standard, which would no longer be the casefor marginal or rural nonattainment areas or areasaffected by transport where the 1-hour standard isreinstated.

24 E.g.,‘‘Extension of Attainment Dates forDownwind Transport Areas,’’ from Richard Wilson,Acting Assistant Administrator for Air andRadiation, dated July 16, 1998, published at 64 FR14441, March 25, 1999.

more recent air quality data indicatesthat a violation has occurred. The EPAintends to complete rulemaking prior tothe applicability date of this rule todetermine the eligibility of these areasto use EPA’s May 10, 1995 clean datapolicy. (Reasonable Further Progress,Attainment Demonstration, and RelatedRequirements for Ozone NonattainmentAreas Meeting the Ozone NationalAmbient Air Quality Standard, John S.Seitz).

The EPA acknowledges thatreinstating the designations as they wereprior to revocation arguably mayproduce some inequities among areas;however, these potential inequities areinherent in the redesignation process setforth in section 107. As provided insection III.D, above, Congress providedEPA with discretion in determiningwhether to redesignate areas fromattainment to nonattainment andspecified factors for EPA to consider. Incomparison, Congress prohibited EPAfrom redesignating an area fromnonattainment to attainment unless EPAdetermined that the area meets fivespecific criteria. In addition, anyredesignation must occur throughnotice-and-comment rulemaking. Thus,at any point in time, an area can beattaining the standard, yet still bedesignated nonattainment, or designatedattainment and be violating thestandard, including the period whilerulemaking to effect a redesignation isproceeding.22

Areas where EPA is today reinstatingthe applicability of the 1-hour standardwill be placed back into the sameposition they were in prior torevocation. The EPA does not believethat this creates any additionalinequities for these areas. It is true thatEPA had previously relieved areas of theobligation to develop a maintenanceplan for the 1-hour standard since theywere to begin implementing the 8-hourstandard. However, since it is nowuncertain when areas will be required toimplement the 8-hour standard, EPAdoes not believe it is inequitable torequire these areas, as any other area, todevelop maintenance plans prior toredesignating them to attainment.

Comment: A few commenters maderequests that specific types of areas notbe designated nonattainment. Onecommenter suggested that EPA shoulddesignate as attainment areas that werepreviously designated marginal or rural

transport areas and that are cleanwithout requiring redesignation. A fewcommenters suggested that EPA notpenalize areas with violations where thecause of the violations is clearly one oftransport and dislike the ‘‘unfair’’ labelof nonattainment.

Response: For the reasons providedabove, EPA does not see a legal avenuefor changing the designation of marginalor rural nonattainment areas or areasaffected by transport based solely on thereinstatement of the standard. Nor dothe commenters identify a legalmechanism for treating these areasdifferently from other nonattainmentareas with clean data.23 Somecommenters set forth conflictingarguments, arguing that EPA shouldgenerally establish the designations thatwere in place at the time of therevocation while simultaneouslyclaiming that certain types of areasshould be designated based on currentair quality. The EPA does not see howit can reconcile these conflictingpositions. As provided above, EPAbelieves the only proper interpretationof this reinstatement action is that prioractions are reversed such that priordesignations are put back into place.The EPA will consider current airquality data in determining whether toredesignate areas under section107(d)(3).

In addition, EPA already has providedrelief to areas subject to transport in anumber of ways. Such areas maycontinue to take advantage ofappropriate EPA policy relating to areasaffected by transport.24 In addition, EPAhas issued final rules requiring States orsources to address transported NOX andozone in accordance with section110(a)(2)(D) of the CAA. Final NOX SIPCall Rule (63 FR 57356, October 27,1998); Final Rule on Section 126Petitions (64 FR 28250, May 25, 1999).Areas affected by transport will benefitfrom these rules.

Comment: Some commenters wereconcerned about redesignation requestsand maintenance plans submitted priorto the time that EPA determined that the

1-hour standard no longer applied.These commenters thought that it wouldbe unfair for EPA to require the areas toupdate the maintenance plan to providemaintenance for 10 years from the timeof EPA’s approval.

Response: The EPA appreciates theconcerns of those few areas that mayhave had pending redesignationrequests that demonstrate continuedmaintenance for some period shorterthan 10 years from the time of EPA’sfinal action, due to the passage of time.In such areas, EPA will work with thoseStates and respective transportationagencies to develop technically soundfuture budgets. Such future emissionsprojections will consider growth forexisting and future sources, forecastingfor vehicle miles traveled, otherfederally mandated programs,particularly the more recent mobilefuels rules and other applicablemeasures; the resulting budgets willundergo normal public process review.The EPA will work with the affectedareas on an individual basis todetermine the extent to whichadditional maintenance demonstrationsmay be needed to support redesignation,and will take appropriate final action onmaintenance demonstrations inconnection with future action onpending redesignation requests.

G. Areas Designated NonattainmentWith Violations Since Revocation

For areas designated nonattainmentwith violations since the standard wasrevoked in those areas, EPA proposedthat the nonattainment designationwould again apply and that the areawould be subject to the subpart 2requirements once the reinstatementbecame effective. The EPA proposedthat these areas have a reasonable timeto meet the applicable planningrequirements and that EPA would workwith each area to establish a submittalschedule. This only applies to one area,Sussex Co., DE., based on 1996–98 data.

Comment: Most commenters did notraise separate issues with respect to thisspecific group of areas. A fewcommenters specifically noted that theysupported reinstating the nonattainmentdesignation for these areas. Somecommenters requested EPA to be clearabout what the implications are forreinstatement. In particular, they wereconcerned about what planning andcontrol requirements might apply andwhat would be the timing.

Response: The planning and controlrequirements that will apply for thisarea are the applicable planning andcontrol requirements in subpart 2 of theCAA. The EPA will work with Delawareto determine appropriate SIP submittal



25 See footnote 9, above.

deadlines for any programs that havenot yet been submitted.

H. Effective Date and ApplicabilityDates of Reinstatement

The EPA proposed to delay theeffective date 25 of any finalreinstatement notice by 90 days in orderto provide areas with a short period oftime in which to prepare for theapplicability of conformity and newsource requirements which will betriggered by the reinstatement of the 1-hour standard and the designations forthat standard. In the final rule, EPA hasretained the 90-day effective date.However, for areas that were designatedas nonattainment at the time EPArevoked the 1-hour standard and thathave continued to have clean air qualitysince revocation, EPA is establishing anapplicability date for the reinstatementof up to 180 days after publication of thefinal rule. These areas are listed in Table1. During this period, EPA will reviewany pending redesignation requests orrequests that may be submitted shortlyafter this final action is published. IfEPA is able to complete finalrulemaking action to redesignate an areato attainment during that 180-dayperiod, EPA will provide in the finalredesignation rule that the area will bedesignated attainment as of theapplicability date of this rule, so that bythe time reinstatement is applicable forany such area, the area will receive anattainment designation. In addition, ifStates are able to submit redesignationrequests and EPA is able to process suchrequests to the point of final action priorto 180 days from publication, the finalaction approving the redesignation mayprovide that the applicability date of thereinstatement will be the same date asthe effective date of the redesignationapproval, so that the redesignations willoccur simultaneously with thereinstatement. As mentioned before, the45 areas listed in Table 1 may elect tosubmit redesignation requests.

Comment: Some commentersdisagreed with the proposed 90-daydelay in effectiveness, claiming it wouldbe too short a time frame to completeconformity determinations ontransportation improvement plans(TIPs) or for redesignation to occur. Onecommenter suggested a 180-day delay inthe effective date. Other commentersbelieved that the final action reinstatingthe standard and the associateddesignation should be effectiveimmediately. Finally, some commenterssupported EPA’s proposal to make thereinstatement and the associated

designations effective 90 days afterpublication.

Response: With respect to theeffective date of the rule, EPA hasdetermined, based upon the commentssubmitted, that a 90-day delayedeffective date is an appropriate timeperiod for most areas. The time from theOctober 25th proposal to the end of the90-day period is approximately 10months. The EPA believes this period issufficient for States to complete airquality analyses for conformitydeterminations on transportation plansprior to the effective date of the finalrule. Thus, areas should not experienceany delays in transportation projects. Atthe same time, reinstatement of thestandard with the associated publichealth and welfare protections will notbe significantly delayed. The EPA doesnot anticipate that areas will attempt tocomplete transportation activitiesinconsistent with reinstatement of the 1-hour standard prior to the effective date,but rather that they will use the delayto ensure they are ready to meet theapplicable requirements when thereinstatement becomes effective. Thus,EPA concludes that a 90-day delayedeffective date is a reasonableaccommodation between the competinginterests of public health protection andtransportation planning for most areas.

The EPA agrees with commenters tothe extent it concludes that up to a 180-day delay in the applicability of thisrule is appropriate for areas that weredesignated nonattainment prior torevocation but that currently have cleanair quality data sufficient to support aredesignation to attainment. Since theseareas have continued to have clean airsince revocation, EPA believes it isappropriate to provide up to anadditional 90-day delay in theapplicability of the rule to allow theseareas time to quickly complete andsubmit redesignation requests and forEPA to act on submitted requests.Where EPA approves such requests onor before the applicability date of thisrule, the area would be designatedattainment at the time the reinstatementof the 1-hour standard becomesapplicable. The EPA notes again that ifEPA is taking final action to approve aredesignation prior to 180 days frompublication of this rule, the final actionapproving the redesignation mayprovide that the applicability date of thereinstatement will be the same date asthe effective date of the redesignationapproval, so that the redesignations willoccur simultaneously with thereinstatement. Where EPA does notapprove a redesignation request or oneis not submitted, the area will receivethe nonattainment designation which

applied to the area prior to revocationupon the applicability date of this rule.

The EPA notes that all of these areaswill again be subject to conformity uponthe applicability date of thereinstatement of the 1-hour standardand associated designations, sinceconformity applies to bothnonattainment and maintenance areas.As indicated above, EPA anticipates thatareas will use the delay to completemodeling efforts and the consultationprocess so that they can have aconforming plan and TIP in place by theapplicability date.

I. Sanction and FIP Clocks

The EPA’s proposed rule providedthat any sanctions and FIP clocks thatwere running at the time of therevocation should restart at the pointthat they left off. In other words, if therewere 6 months remaining in the 2-yearperiod for promulgation of a FIP, thoseremaining 6 months would start to runfor that area on the applicability date ofthis action. The EPA is retaining thisapproach in the final rule.

Comment: Some commenters statedthat areas should not be subject to anypenalties or sanctions. Anothercommenter requested that EPA imposesanctions immediately not only forthose areas for which a clock wasrunning but also for those areas whichmay not have submitted a required SIPbut for which EPA never made a findingthat started sanctions and FIP clocks.This commenter suggested thatsanctions should be imposed no laterthan 90 days after the effective date ofthe reinstatement for all such areas. Incontrast, a number of commenterssupported EPA’s approach. Thesecommenters generally contended thattreating the clocks as if they continuedto run during the time when thestandard did not apply would beconsidered enforcing the standard whenit was not in effect. One commenterseemed to support starting the clockwhere it left off at the time of therevocation, but noted that sanctionclocks with time remaining should notallow States to delay progress. Thecommenter states that areas violatingthe 1-hour standard or contributing toviolations in other areas must moveforward ‘‘as expeditiously aspracticable.’’

Response: The EPA believes that themost equitable approach is to restartclocks for sanctions or FIPs where theyleft off at the time of the revocation.Because States and sources relied onEPA’s final rule determining that thestandard no longer applied, States werenot affirmatively moving forward with



26 One commenter suggests that EPA’s actionsrevoking the 1-hour standard and relateddesignations were not legally valid at the time theywere taken. Thus, this commenter claims, that rulecannot support a further delay in sanctions or FIPs.The EPA disagrees. The EPA revoked the standardin full compliance with its regulation, 40 CFR50.9(b), which was not challenged at the time it waspromulgated.

27 See footnote 9 and section H. above forexplanation of terms ‘‘effective date’’ and‘‘applicability date.’’

28 The EPA’s conformity regulations requireStates to redetermine conformity for alltransportation plans and programs every 3 years. 40CFR 93.104(b)(3) and (c)(3). The regulations alsorequire a conformity determination within 18months of various SIP submittal and approvalactions. 40 CFR 93.104(e).

1-hour SIPs. 26 Thus, EPA believes thatit would be unfair to States and affectedsources to treat those clocks as if theycontinued to run during the time thatthe 1-hour standard no longer applied.

Similarly, EPA does not believe thatit has authority, nor would it beappropriate, to begin these clocks overagain upon reinstatement or to treatthese clocks as no longer in effect. TheFIP and sanctions obligations undersections 110 and 179 of the CAA werepreviously triggered for a State’s failureto make a complete SIP submission oran approvable submission as requiredunder the CAA. By today’s action, areaswill once again be subject to the samerequirements to make submissions.There is no basis for ignoring ordischarging the State’s obligation withrespect to these submissions. Moreover,EPA agrees that sanctions clocks shouldnot be treated by States as a ‘‘graceperiod’’ that allows deferral ofcompliance dates. Where a sanctionsclock is in place, States should submitplans to stop the clock as expeditiouslyas practicable and should not delaysubmission until the last minute beforesanctions are put into place.

Because EPA is taking action to putareas back in the place they were inprior to the revocation, the mostappropriate course of action is to restartthese clocks where they left off.Therefore, upon the applicability date oftoday’s action, any sanctions or FIPclocks that were running based on aState’s default for a required submissionwill restart at the point it was on theeffective date of the revocation. Statesshould work to submit SIPs asexpeditiously as practicable. Anyquestions regarding the status of asanction or FIP clock for a specific areashould be directed to the appropriateEPA Regional Office. Finally EPA hasno authority to impose sanctions whereEPA has not made appropriate findingsto trigger clocks under section 179.

J. Conformity

The EPA proposed that conformitywould apply upon the effective date ofthe rule to all areas again designatednonattainment. The EPA noted thatthese areas would need to have aconforming transportation plan andprogram in place by the effective date ofthe rule in order to fund new

transportation projects after that date.The EPA also noted that conformity hascontinued to apply to all attainmentareas with maintenance plans even afterrevocation, and that conformity does notapply at all to attainment areas withoutmaintenance plans. Upon theapplicability date 27 of this final action,conformity will apply to all designatednonattainment and maintenance areasas proposed.

Several commenters expressedconcerns about the conformityrequirements that apply tononattainment and maintenance areasand the timing of conformitydeterminations. The specific commentsand responses follow.

Comment: The transportationconformity rule requires conformity tobe determined at least every 3 years.Commenters requested that we notconsider the 3-year clock to have beenrunning in nonattainment areas wherethe 1-hour ozone standard was revokedand conformity did not apply.

Response: We agree that in ozonenonattainment areas where the ozonestandard was revoked and conformitystopped applying, any of the 3-year or18-month clocks (described in 40 CFR93.104 28) that were running at the timeof the revocation were stayed on theeffective date of the revocation. On theapplicability date of this final rule,those clocks will pick up again at thepoint where they left off.

In practice, this means that if anozone nonattainment area had aconforming TIP at the time of therevocation and did not amend the planand TIP with respect to any non-exemptprojects during the time conformity didnot apply, the transportation plan andTIP would continue to be considered‘‘currently conforming’’ even if morethan 3 years have elapsed since theconformity determination.

The area would need to documentthat the transportation plan and TIPhave not changed since the time of thelast conformity determination in amanner that would have required a newconformity determination. The areashould also clearly identify how muchtime remains on the 3-year clock andany 18-month clock that was triggeredby 40 CFR 93.104.

We are not concerned that thetemporary halt of the clocks in 40 CFR

93.104 will result in transportationplans and TIPs that are relying on veryold conformity determinations. TheDepartment of Transportation (DOT)requires transportation plans and TIPsto be regularly updated, and thoseplanning clocks have been runningregardless of the revocation. The planand TIP updates require conformitydeterminations. Therefore, any plansand TIPs with conformitydeterminations from before therevocation will be updated soon underDOT’s planning regulations.

For any plans and TIPs that wereamended with respect to non-exemptprojects while the ozone standard wasrevoked, a new conformitydetermination will be required by thetime the reinstatement is applicable.This is because these plans and TIPswill generally not yet have been foundto conform and would have to be foundto conform by the applicability date ofreinstatement to enable projects toproceed.

Comment: One commenter askedwhat process is required for areas thatvoluntarily complied with conformityrequirements while the ozone standardwas revoked.

Response: If an area amended its planand TIP while the ozone standard wasrevoked, but the amendment(s) fullymet the requirements of the conformityrule (including public participation), thearea would simply need to documentthis and receive confirmation from theFederal agencies that the transportationplan and TIP are considered ‘‘currentlyconforming.’’

Comment: Some commenters wereconcerned that they do not have enoughtime to determine conformity before thereinstatement is applicable, and/or thatit is burdensome to determineconformity of the current plan and TIPwhen they are updating the plan andTIP very soon (which will also requirea conformity determination).

Response: We understand that thisfinal rule changes the usual cycle fordetermining conformity. Counting fromthe time we proposed to reinstate thestandard, areas will have had at least tenmonths to complete the conformityprocess prior to the applicability date ofthis rule. We believe this is a reasonabletime frame, although we recognize thatthe timing for this conformity processmay not be optimal for some areas.

We must balance the desire foradditional time for transportationplanning with the need to protect publichealth with the 1-hour ozone standardand statutory requirement forconformity determinations. In someareas, transportation investments wereplanned or approved during the



revocation without a demonstration thatthey will not interfere with attainmentof the one-hour ozone standard. It isimportant to conduct such ademonstration expeditiously so thatareas do not irreversibly commit totransportation projects that areinconsistent with healthy air.

Comment: One commenter stated thatthe proposed criteria for conformity arenot consistent with the March 2, 1999decision of the Court of Appeals in EDFv. EPA, 167 F.3d 641,650 (1999) onconformity. The commenter argues thatthe court required EPA to develop a testto ensure conformity consistent withCAA 176(c)(1) and that this must bedone now for all areas where thestandard is to be reinstated.

Response: Conformity determinationsshould comply with the CAA, asrecently interpreted in the EPA andDOT guidance issued in response to theMarch 1999 court decision (EPA’s May14, 1999 guidance entitled, ‘‘ConformityGuidance on Implementation of March2, 1999 Conformity Court Decision’’ andDOT’s June 18, 1999 guidance entitled,‘‘Additional Supplemental Guidance forthe Implementation of the Circuit CourtDecision Affecting TransportationConformity’’). We believe that theseguidance documents are consistent withthe court’s decision and that conformitydeterminations performed consistentwith the guidance are legally sound. Wewill be formally proposing to amend thetransportation conformity rule toincorporate this guidance, pursuant toCAA section 176(c)(4)(A).

The commenter appears to believethat the court decision required EPA todevelop additional criteria to satisfy theobligations of section 176(c)(1) of theCAA, which require Federal agenciesand Metropolitan PlanningOrganizations (MPOs) to determine thatFederal actions will not interfere withtimely attainment, in situations wherethey are determining conformity tobudgets in submitted SIPs. However,EPA believes that the court in actualitymerely remanded EPA’s rules, statingthat ‘‘where EPA fails to determine theadequacy of motor vehicle emissionsbudgets in a SIP revision within 45 daysof submission, * * * there is no reasonto believe that transportation plans andprograms conforming to the submittedbudgets will [meet the statutory tests insection 176(c)(1)(B)].’’ The EPAinterprets this aspect of the decision torequire it to revise its regulations tomandate that EPA make affirmativefindings of adequacy on all submittedSIPs before they can be used forconformity purposes. The procedure fordoing this is outlined in the guidancementioned above. The EPA does not

believe the court addressed anydeficiency in EPA’s regulationsgoverning conformity determinations insituations where EPA has made apositive finding of adequacy. The EPAconcludes that the court only remandedthe aspect of EPA’s regulations at 40CFR 93.118(e)(1) which allows use ofsubmitted SIPs which EPA has not yetfound adequate, since it did not remandeither EPA’s regulations at 40 CFR93.118(e)(4) establishing criteria forfinding budgets adequate or 93.118(e)(6)requiring additional findings by Federalagencies and MPOs where conformitydeterminations are made to submittedSIPs. Therefore, EPA believes thatconformity determinations consistentwith these two provisions and ourguidance on finding budgets adequatefully satisfy the requirements of theCAA and we intend to revise ourregulations consistent with thatguidance. Of course, commenters willhave the opportunity to comment onthose regulatory changes when they areproposed and to raise any issuesassociated with EPA’s interpretation ofthe court opinion at that time. The EPAdoes not believe that such comments aredirectly relevant to this rulemaking and,therefore, is not making any changes tothe conformity rules in connection withthis final action.

Comment: One commenter arguedthat conformity to adequate SIP budgetsin nonattainment areas, should continueeven after any future revocations untilnew adequate budgets are submitted forthe 8-hour standard.

Response: Section 176(c)(5) of theCAA clearly provides that conformityrequirements only apply innonattainment areas and areas that hadbeen nonattainment and weresubsequently redesignated to attainmentand are subject to the requirement todevelop a maintenance plan. Sincenonattainment areas where EPA may inthe future revoke the 1-hour standardonce an 8-hour standard becomes fullyenforceable will no longer be designatednonattainment or subject to therequirement to submit a maintenanceplan, for the reasons explained above,EPA concludes that it would have noauthority under section 176(c) to requireconformity to previously submitted 1-hour budgets after any futurerevocations.

K. New Source ReviewIn the October 25th proposal, EPA

solicited comment on what NSRrequirements should apply in areas thathad, subsequent to our findings that the1-hour standard no longer applied,revoked their nonattainment NSRprograms. Specifically, EPA asked

whether 40 CFR part 51, Appendix Sshould be followed or the higher offset/major source thresholds in subpart 2 ofthe CAA should be followed innonattainment areas where the SIP lacksthe applicable nonattainment NSRprovisions.

Comment: Several commenterswanted flexibility in applying NSRrequirements. There was a mixedreaction for and against using 40 CFRappendix S. As to the question ofwhether States must issue permitsconsistent with the additionalrequirements of subpart 2, even in theabsence of an approved NSR SIP, onecommenter stated that it was notsupportive of any EPA action thatwould cause enforcement of NSR onfacilities that were or are under no legalobligation to comply with NSRrequirements. Another commenterurged EPA to require sources to complywith subpart 2 notwithstanding the lackof an approved SIP, citing a 1992 EPApolicy memorandum as support.

Response: The EPA solicitedcomment on how to address areas thatwere designated nonattainment prior tothe findings that the 1-hour standard nolonger applied and which, sincerevocation, had amended their SIPs toremove the applicable nonattainmentNSR provisions. The EPA hasdetermined that it is unnecessary toresolve this question in this rulemaking,as we have determined that no area hasamended its SIP since thenonattainment designations wereremoved. Thus, the applicable SIPs ineach area will specify the nonattainmentNSR responsibilities of sources in thearea, without any action by EPA.

Comment: Sources that have appliedfor PSD permits during the period thatthe 1-hour ozone standard did not applyshould not have to seek part D NSRpermits. Allowing sources withcomplete applications to avoid morestringent requirements is consistentwith EPA policy. Such an approach isalso consistent with how EPA actedfollowing the adoption of PM10 as theindicator for particulate matter in 1987.At that time, EPA allowed sources withcomplete PSD permit applications thatdid not account for the sources’ PM10

emissions to be grandfathered.Response: Whether or not sources

must apply for part D nonattainmentNSR permits upon reinstatement of the1-hour standard will be determined bythe applicable SIP. The EPA expectsthat most, if not all, SIPs already specifythat sources in designatednonattainment areas must obtain part Dpermits. Accordingly, some sources mayhave to revise their permit applications.Even if EPA were to agree that it would



29 One commenter notes that some areas shouldhave been on notice that revocations werequestionable since one action promulgatingrevocations was not published in the FederalRegister until after May 14, 1999, the date of theadverse court decision in ATA (64 FR 30911, June9, 1999). However, that final action of theAdministrator was taken (final rulemaking noticesigned by the Administrator) on May 12, 1999, priorto the court decision; only publication occurredafter the decision. The EPA did not take any furtheractions revoking the 1-hour standard in any areasafter the date of the ATA decision.

be appropriate to allow such sources toobtain PSD permits rather thannonattainment NSR permits, EPAcannot override by policy the legalrequirements of a more stringentapplicable SIP. Regarding the PM10

transition policy to which thecommenter refers, that policy isinapplicable in the present situationbecause it did not deal with the kind ofsituation at issue currently—whereareas will be switching from onedesignation status (no designation) tononattainment. The EPA had concludedin that rulemaking that part D, includingpart D NSR, did not apply at all to therevised particulate matter NAAQS, sothere was not a question about whichNSR program would apply. See 52 FR24672, 24678 (July 1, 1987).

L. Miscellaneous CommentsComment: One commenter noted that

EPA should notify the public of theterms of a stipulation agreement reachedbetween EPA and the EnvironmentalDefense Fund (EDF) wherein EPAagreed to accept comment on certainitems in the reinstatement notice.

Response: In its notice reopening thecomment period on Dec. 8, 1999, EPAexplicitly provided that it would acceptcomment on the list of issues recited inthe stipulation filed in EDF v. EPA,(D.C. Cir., No. 98–1363). (64 FR 68659,December 8, 1999).

Comment: Several commenterssupported applying the reinstatementretroactively, such that areas would betreated as if the standard and theassociated designations have alwaysapplied. Some were not supportive ofretroactively applying the 1-hourstandard during the time it was revoked.With respect to conformitydeterminations, one commenterbelieved that we shouldn’t allow‘‘grandfathering’’ of projects if priorconformity determinations would havelapsed during the time the standard wasnot applicable; they believe that in caseswhere it is not possible to reverseactions, then they must be subject tosome mitigation procedure to addressactions that allowed for emissionincreases during that time.

Response: The EPA concludes that itis not appropriate to apply thereinstatement of the 1-hour standardretroactively. The EPA believes that ithad full authority to revoke the 1-hourstandard initially, and that its actionswere legal and proper at the time theywere taken. Although EPA nowconcludes that it should rescind thoseactions due to changed circumstances, itwould be unfair to areas that had reliedon the initial revocations (and tosources located in those areas) to apply

the rescissions retroactively. Many areastook actions during the period of timethat the 1-hour standard was notapplicable that properly relied on theinapplicability of that standard. Rulesaltering prior actions are generallyapplied only prospectively and areapplied retroactively only in unusualcases, for instance where an agency didnot have the authority to take a prioraction initially. Courts generally viewretroactive application of administrativerules with disfavor unless suchapplication is specifically sanctioned bystatute. Bowen v. Georgetown UniversityHospital, 488 U.S. 204 (1988). The CAAdoes not specifically provide forretroactive application of regulationsunder title I. Therefore, although EPAmight have authority to apply thereinstatement retroactively if a courtdetermined that EPA’s action inrevoking the standard was illegal, EPAdoes not believe it is appropriate to doso here where EPA believes it was fullyauthorized to revoke the standard at thetime it took such action.

The EPA also concludes for similarreasons that it would not be appropriatefor conformity purposes to treatconformity determinations as havinglapsed during the time that the 1-hourstandard was not applicable to an area.Because the 1-hour standard no longerapplied during that period, areas werenot on notice that conformitydeterminations were to lapse. It wouldbe equally unfair to areas to achieve asimilar result by denying grandfatheringstatus under the conformity rules to anyproject approved during a time periodwhen conformity status would havelapsed if the standard had beenapplicable. The EPA concludes thatareas should be allowed to continue torely on the inapplicability of the 1-hourstandard during the period betweenrevocation and reinstatement becauseEPA had the authority to revoke thestandard and properly revoked itinitially.29

For these same reasons, EPAconcludes that where highway projectsor new sources have already beenconstructed, areas should not berequired to immediately implementmitigation measures to remedy any

resulting emissions increases. Areas willeffectively have to provide formitigation in future transportation andair quality planning once the 1-hourstandard is reinstated. All future airquality planning for attainment andreasonable further progress as well asconformity determinations will have toaccount for emissions from suchactivities. However, EPA believes that itwould be inequitable to require areas toimmediately institute specificmitigation measures to account for anyemissions increases that may haveoccurred during the time that thestandard was not applicable to an area.

Comment: Several commenters tookthe opportunity to comment on the 8-hour ozone standard. Many requestedthat designations for the 8-hourstandard not be made until legal issuesare resolved. Many asked for guidanceto States on meeting the 8-hour standardin the interim. Several called upon theAgency to revoke the 8-hour standard.

Response: The numerous commentsconcerning the 8-hour standard,including those relating to designationsunder the 8-hour standard, guidance onimplementation of the 8-hour standard,and requests for revocation of the 8-hourstandard, are not relevant to thisrulemaking on reinstatement of the 1-hour standard. The EPA will addressissues relating to the 8-hour standard inseparate rulemaking actions or guidancedocuments.

Comment: One commenter suggestedthat we explore the Flexible AttainmentRegion (FAR) approach to provideflexibility to States in determiningmeasures to prevent air qualitydeterioration and to improve air quality.The commenter suggests that EPA givethese ‘‘voluntary programs’’ time towork before triggering nonattainmentdesignations. The same commenter alsorequests EPA to extend to ozone areasthe flexibility provided in EPA’s draftguidance for PM–10 nonattaiment areaswith respect to limited maintenanceplans.

Response: The EPA has used the FARapproach in the past with respect toareas designated attainment but that areviolating the ozone standard. Asprovided above, EPA has somediscretion in deciding whether toredesignate such areas asnonattainment. In exercising thatdiscretion, EPA may consider ‘‘planningand control’’ activities. Thus, in thepast, EPA has not moved forward toredesignate to nonattainment attainmentareas that were voluntarily adopting andimplementing measures to addressviolations. The EPA plans to continuethis approach for such areas asexplained in sections III.D and E, above.



30 See Docket A–99–22, III–B–04, ‘‘PreliminaryAssessment of the Incremental Burden Associatedwith Reinstatement of the 1-Hour Ozone Standardfor UMRA, dated October 14, 1999.

However, as also explained above, EPAdoes not believe it has the authority toreinstate the standard and not designateas nonattainment those areas designatedas nonattainment at the time of therevocation action. These areas would besubject to the specific planningrequirements that Congress providedunder the CAA until they qualify forredesignation. The EPA cannot ignorethe statutory mandate in favor of moreflexible means of achieving attainmentthat could be allowed under the FARapproach. Therefore, designatednonattainment areas cannot use a FARbecause the statutory requirementsapply.

With respect to the commentregarding EPA’s draft limitedmaintenance plan guidance for PM–10areas seeking redesignation fromnonattainment to attainment, EPA notesthat it has an existing limitedmaintenance plan policy for ozone(‘‘Limited Maintenance Plan Option forNonclassifiable Ozone NonattainmentAreas,’’ November 16, 1994, SallyShaver) This policy provides someflexibility, e.g., no requirement toproject emissions out into the future, noneed for maintenance demonstrationsince met by meeting the NAAQS, etc.The commenter appears not to recognizethat such a policy exists and does notfurther explain what flexibilities in thedraft PM–10 policy they would likeextended to ozone areas.

IV. What Administrative RequirementsAre Considered in Today’s Final Rule?

A. Executive Order 12866: RegulatoryImpact Analysis

Under Executive Order 12866, [58 FR51,735 (October 4, 1993)] the Agencymust determine whether the regulatoryaction is ‘‘significant’’ and thereforesubject to Office of Management andBudget (OMB) review and therequirements of the Executive Order.The Order defines ‘‘significantregulatory action’’ as one that is likelyto result in a rule that may:

(1) Have an annual effect on theeconomy of $100 million or more oradversely affect in a material way theeconomy, a sector of the economy,productivity, competition, jobs, theenvironment, public health or safety, orState, local, or tribal governments orcommunities;

(2) Create a serious inconsistency orotherwise interfere with an action takenor planned by another agency;

(3) Materially alter the budgetaryimpact of entitlements, grants, user fees,or loan programs or the rights andobligations of recipients thereof; or

(4) Raise novel legal or policy issuesarising out of legal mandates, thePresident’s priorities, or the principlesset forth in the Executive Order.

It has been determined that this finalrule is a ‘‘significant regulatory action’’under the terms of Executive Order12866; therefore, it was submitted toOMB for their review.

B. Regulatory Flexibility Act

Under the Regulatory Flexibility Act(RFA), 5 U.S.C. 601 et seq., EPA mustprepare a regulatory flexibility analysisassessing the impact of any proposed orfinal rule on small entities (5 U.S.C. 603and 604), unless EPA certifies that therule will not have a significant impacton a substantial number of smallentities. Small entities include smallbusinesses, small not-for-profitenterprises, and government entitieswith jurisdiction over populations ofless than 50,000. The EPA is certifyingthat this final rule will not have asignificant impact on a substantialnumber of small entities because thedetermination that the 1-hour standardagain applies does not itself directlyimpose any new requirements on smallentities. See Mid-Tex ElectricCooperative, Inc. v. FERC, 773 F.2d 327(D.C. Cir. 1985) (agency’s certificationneed only consider the rule’s impact onentities subject to the requirements ofthe rule). Instead, this rule merelyestablishes that the 1-hour standardagain applies in certain areas. For themost part, any requirements applicableto small entities that may indirectlyapply as a result of this action would beimposed independently by the Stateunder its SIP, not by EPA through thisaction. Moreover, to the extent this rulewould automatically trigger theapplicability of certain SIP requirementsto small entities (e.g., NSR), this rulecannot itself be tailored to address smallentities that would be subject to thoserequirements.

One requirement that may applyimmediately upon this action to alldesignated nonattainment areas is therequirement under CAA section 176(c)and associated regulations todemonstrate conformity of Federalactions to SIPs. However, those rulesonly apply directly to Federal agenciesand MPOs, which by definition aredesignated only for metropolitan areaswith a population of at least 50,000 andthus do not meet the definition of smallentities under the RFA. Therefore, Icertify that this action will not have asignificant impact on a substantialnumber of small entities within themeaning of those terms for RFApurposes.

C. Unfunded MandatesTitle II of the Unfunded Mandates

Reform Act of 1995 (UMRA), PublicLaw 104–4, establishes requirements forFederal agencies to assess the effects oftheir regulatory actions on State, local,and tribal governments, and the privatesector. Under section 202 of UMRA,EPA generally must prepare a writtenstatement, including a cost-benefitanalysis, for proposed and final ruleswith ‘‘Federal mandates’’ that mayresult in expenditures by State, local,and tribal governments, in the aggregate,or by the private sector, of $100 millionor more in any one year. Beforepromulgating an EPA rule for which awritten statement is needed, section 205of UMRA generally requires EPA toidentify and consider a reasonablenumber of regulatory alternatives andadopt the least costly, most cost-effective or least burdensome alternativethat achieves the objectives of the rule.The provisions of section 205 do notapply when they are inconsistent withapplicable law. Moreover, section 205allows EPA to adopt an alternative otherthan the least costly, most cost-effectiveor least burdensome alternative if theAdministrator publishes with the finalrule an explanation why that alternativewas not adopted. Before EPA establishesany regulatory requirements that maysignificantly or uniquely affect smallgovernments, including tribalgovernments, it mush have developedunder section 203 of UMRA a smallgovernment agency plan. The plan mustprovide for notifying potentiallyaffected small governments, enablingofficials of affected small governmentsto have meaningful and timely input inthe development of EPA regulatoryproposals with significant Federalintergovernmental mandates, andinforming, educating, and advisingsmall governments on compliance withthe regulatory requirements.

Today’s final action does not includea Federal mandate within the meaningof UMRA that may result inexpenditures of $100 million or more inany one year by either State, local, ortribal governments in the aggregate or tothe private sector. This rule wouldreinstate the applicability of the 1-hourozone standard and alter the designationstatus of areas. The consequences of thisaction may result in some additionalcosts within the affected areas, but thesecosts would not exceed $100 million peryear in the aggregate.30 In view of recentconcerns about increased gas prices in




certain areas, we specifically note thatthis action will not impose anyrequirements on gasoline and will notaffect current gas prices.

One mandate that may apply as aconsequence of this action to alldesignated nonattainment areas is therequirement under CAA section 176(c)and associated regulations todemonstrate conformity of Federalactions to SIPs. These rules apply toFederal agencies and MPOs makingconformity determinations. The EPAconcludes that such conformitydeterminations will not cost $100million or more in the aggregateannually.31

In addition, some areas with recent airquality violations will have to take theadditional steps specified in theirmaintenance plans to limit emissions ofair pollutants. These measures could,for example, include revising thethreshold for NSR, establishingreasonable available control technology(RACT) level control for additionalsources, and establishing or enhancinginspection and maintenance (I/M)programs within the area. Thesemeasures vary substantially in terms ofthe expected emissions reductions andtheir potential cost. Because the affectedjurisdictions have some flexibility tochoose among these measures, it isdifficult to estimate the overall cost ofthese additional controls. The EPAbelieves that the affected areas arealready carrying out many of the otherobligations associated with this action.For example, most areas that wouldhave a nonattainment designationreinstated upon reinstatement of the 1-hour standard already have NSRrequirements under their existing SIPprograms. In addition, many of theseareas are located in the Northeast OzoneTransport Region and are alreadycarrying out many of the requirementsassociated with the reinstatement of the1-hour standard. Therefore, EPAbelieves that any new controls imposedas a result of this action will not cost inthe aggregate $100 million or moreannually. Thus, this Federal action willnot impose mandates that will requireexpenditures of $100 million or more inthe aggregate in any one year.

D. Executive Order 13045: Protection ofChildren From Environmental HealthRisks and Safety Risks

Executive Order 13045: ‘‘Protection ofChildren from Environmental HealthRisks and Safety Risks’’ (62 FR 19885,April 23, 1997) applies to any rule that:(1) is determined to be ‘‘economicallysignificant’’ as defined under Executive

Order 12866, and (2) concerns anenvironmental health or safety risk thatEPA has reason to believe may have adisproportionate effect on children. Ifthe regulatory action meets both criteria,the Agency must evaluate theenvironmental health or safety effects ofthe planned rule on children, andexplain why the planned regulation ispreferable to other potentially effectiveand reasonably feasible alternativesconsidered by the Agency.

The EPA interprets Executive Order13045 as applying only to those majorregulatory actions that are based onhealth or safety risks, such that theanalysis required under section 5–501 ofthe Order has the potential to influencethe regulation. This final rule is notsubject to Executive Order 13045because it does not meet either of theabove criteria. It is not economicallysignificant as defined under ExecutiveOrder 12866, and it implements apreviously promulgated health or safety-based Federal standard and does notitself involve decisions that affectenvironmental health or safety risks.

E. Submission to Congress and theGeneral Accounting Office

Under 5 U.S.C. 801(a)(1)(A), as addedby the Small Business RegulatoryEnforcement Fairness Act of 1996, EPAsubmitted a report containing this ruleand other required information to theU.S. Senate, the U.S. House ofRepresentatives and the ComptrollerGeneral of the General AccountingOffice prior to publication of the rule intoday’s Federal Register. This rule isnot a ‘‘major rule’’ as defined by 5U.S.C. 804(2).

F. Executive Order 13132: FederalismExecutive Order 13132, entitled

‘‘Federalism’’ (64 FR 43255, August 10,1999), requires EPA to develop anaccountable process to ensure‘‘meaningful and timely input by Stateand local officials in the development ofregulatory policies that have federalismimplications.’’ ‘‘Policies that havefederalism implications’’ is defined inthe Executive Order to includeregulations that have ‘‘substantial directeffects on the States, on the relationshipbetween the national government andthe States, or on the distribution ofpower and responsibilities among thevarious levels of government.’’

Under Section 6 of Executive Order13132, EPA may not issue a regulationthat has federalism implications, thatimposes substantial direct compliancecosts, and that is not required by statute,unless the Federal government providesthe funds necessary to pay the directcompliance costs incurred by State and

local governments, or EPA consults withState and local officials early in theprocess of developing the proposedregulation. The EPA also may not issuea regulation that has federalismimplications and that preempts Statelaw, unless the Agency consults withState and local officials early in theprocess of developing the proposedregulation.

As indicated in the proposal, EPAdoes not believe that this final rule hasfederalism implications within themeaning of the Executive Order. EPAhas reached this conclusion for severalreasons. As discussed above inconnection with UMRA, this action willnot impose substantial directcompliance costs on the States nor willit alter the relationship between thenational government and the States, orthe distribution of power andresponsibilities among the variouslevels of government. As notedpreviously, this rule simply reinstatesthe applicability of the 1-hour ozonestandard and the associated air qualitydesignations for various areas that hadapplied prior to revocation. Theseactions do not preempt any Stateauthority or otherwise affect Stateflexibility to comply with the Clean AirAct. Although reinstatement will alterthe number of areas within variousstates that are designated under the 1-hour standard, it will not alter therelationships that currently existbetween the States and the federalgovernment with respect to areasdesignated under the 1-hour standard.Thus, EPA concludes that therequirements of section 6 of theExecutive Order do not apply to thisrule.

In the spirit of the Executive Orderhowever, the Agency has consultedextensively with representatives of Stateand local governments, includingelected officials. As EPA wasdeveloping the proposal and again whenEPA issued the proposal, we phonedelected officials or their staff for manyof the areas that could be affected by therule to notify them that EPA wasconsidering reinstating the 1-hour ozonestandard and to solicit their advice andconcerns. The EPA also notifiednational organizations of state and localgovernment officials and made EPA staffavailable to discuss the proposed actionwith the organization staff and theirmembers. These organizations includedthe U.S. Conference of Mayors (USCM),the National Conference of BlackMayors, the National GovernorsAssociation, the National Council ofState Legislators, the NationalAssociation of Counties, ECOS,STAPPA/ALAPCO, the National




Association of Local GovernmentEnvironmental Professionals, and theOzone Transport Commission. Forexample, EPA’s Assistant Administratorfor Air and Radiation held a conferencecall with the USCM Energy andEnvironment Committee members whenthe proposal was announced. Inaddition, EPA sent letters to theGovernors and their environmentalcommissioners to ensure that they wereaware of the proposal and couldcomment on it. It was in response toconcerns raised by these contacts thatEPA proposed to delay the effective dateof the reinstatement for 90 days so thatareas would have adequate time tocomply with any requirements triggeredby reinstatement. In addition, based oncomments received from States afterpublication of the proposal, EPAdecided to provide a 180-day delayedapplicability date for areas that weredesignated nonattainment but currentlyhave clean air data. EPA also notes that,while it received no adverse commentsregarding the statements in the proposalconcerning the lack of federalismimplications of this rule, it receivednumerous comments on the rule fromstate and local governments. EPA hasresponded fully to all comments raisedby the various State and localgovernments, as explained above in thesections of this notice describing thecomments and EPA’s response to them.

G. Executive Order 13084: Consultationand Coordination With Indian TribalGovernments

Under Executive Order 13084, EPAmay not issue a regulation that is notrequired by statute that significantly oruniquely affects the communities ofIndian tribal governments, and thatimposes substantial direct compliancecosts on those communities, unless theFederal government provides the fundsnecessary to pay the direct compliancecosts incurred by the tribalgovernments, or EPA consults withthose governments. If EPA complies byconsulting, Executive Order 13084requires EPA to provide to OMB, in aseparately identified section of thepreamble to the rule, a description ofthe extent of EPA’s prior consultationwith representatives of affected tribalgovernments, a summary of the natureof their concerns, and a statementsupporting the need to issue theregulation. In addition, Executive Order13084 requires EPA to develop aneffective process permitting electedofficials and other representatives ofIndian tribal governments ‘‘to providemeaningful and timely input in thedevelopment of regulatory policies on

matters that significantly or uniquelyaffect their communities.’’

Today’s final rule does notsignificantly or uniquely affect thecommunities of Indian tribalgovernments. This final action does notinvolve or impose any requirements thatdirectly affect Indian tribes. UnderEPA’s tribal authority rule, tribes are notrequired to implement CAA programsbut, instead, have the opportunity to doso. Accordingly, the requirements ofsection 3(b) of Executive Order 13084do not apply to this rule.

H. Paperwork Reduction Act

This final action does not contain anyinformation collection requirementswhich require OMB approval under thePaperwork Reduction Act (44 U.S.C.3501 et seq.).

I. Executive Order 12898:Environmental Justice

Under Executive Order 12898, eachFederal agency must make achievingenvironmental justice part of its missionby identifying and addressing, asappropriate, disproportionately highand adverse human health orenvironmental effects of its programs,policies, and activities on minoritiesand low-income populations. Today’sfinal action to reinstate the applicabilityof the 1-hour standard in certain areasdoes not have a disproportionateadverse affect on minorities and low-income populations.

J. National Technology Transfer andAdvancement Act

Section 12 of the National TechnologyTransfer and Advancement Act(NTTAA) of 1995 requires Federalagencies to evaluate existing technicalstandards when developing newregulations. To comply with NTTAA,the EPA must consider and use‘‘voluntary consensus standards’’ (VCS)if available and applicable whendeveloping programs and policiesunless doing so would be inconsistentwith applicable law or otherwiseimpractical.

The EPA believes that VCS areinapplicable to this final action. Today’sfinal action does not require the publicto perform activities conducive to theuse of VCS.

K. Rule Effective Date and ApplicabilityDates

The EPA finds that there is goodcause for this final action to becomeeffective 32 and applicable either 90 or180 days after publication, dependingupon type of area, since this would

afford areas time to get programs, suchas conformity SIPs or redesignationrequests, in place. The EPA believesthese are reasonable periods of time toaccommodate the competing interests ofefficient air quality and transportationplanning and prompt public healthprotection. The EPA has generaladministrative authority under section301(a) of the CAA and 5 U.S.C. 553(d)to establish the effective date andapplicability dates of a rule providedany delay in effective date orapplicability dates is reasonable. ASGIndustries v. Consumer Product SafetyCommission, 593 F.2d 1323, 1335 (D.C.Cir. 1979). A 90- or 180-day delay ineffective or applicability date for a rulewhere areas will have to developvarious SIP emission control programsby the effective or applicability date ofthe rule is reasonable. See Small RefinerLead Phase-Down Task Force v. EPA,705 F.2d 506 (D.C. Cir. 1983) (EPA’sdecision to grant an 8-month periodbetween date of promulgation andeffective date was reasonable whereregulated entities needed time toimplement controls). The longer timeperiod for areas that are notexperiencing violations is reasonablebecause no violations are occurring inthese areas. Moreover, EPA will needadditional time to take final action toredesignate areas as attainment afterStates submit their plans to EPA.

L. Petitions for Judicial Review

Under section 307(b)(1) of the CAA,petitions for judicial review of thisaction must be filed in the United StatesCourt of Appeals for the appropriatecircuit by September 18, 2000. Filing apetition for reconsideration by theAdministrator of this final rule does notaffect the finality of this rule for thepurposes of judicial review nor does itextend the time within which a petitionfor judicial review may be filed, andshall not postpone the effectiveness ofsuch rule or action. This action may notbe challenged later in proceedings toenforce its requirements (see section307(b)(2)).
