Rescinding Findings That the 1-Hour Ozone Standard No Longer 
Applies in Certain Areas

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: Today, EPA is rescinding its prior findings that the 1-hour 
ozone national ambient air quality standard (NAAQS) and the 
accompanying designations and classifications no longer apply in 
certain areas. As part of a transition to a new, more protective 8-hour 
ozone standard (promulgated in July 1997), in 1998 and 1999, EPA took 
final action determining that the 1-hour standard would no longer apply 
in almost 3,000 counties. Now, however, the public health protection 
that would be afforded by the 8-hour ozone standard is being delayed 
because continued litigation regarding the 8-hour ozone standard has 
created uncertainty regarding when and whether EPA may be able to fully 
implement that standard. It is important to have a fully enforceable 
Federal ozone standard to help protect people from the respiratory and 
other harmful effects of ozone pollution. Under this final rule, the 
designations and classifications that previously applied in such areas 
with respect to the 1-hour standard would also be reinstated. This rule 
will become effective in 90 days for most areas, and will become 
applicable in 180 days for areas with clean air quality data that had a 
nonattainment designation when the 1-hour standard was revoked. 
Furthermore, today EPA is taking final action to amend 40 CFR 50.9(b) 
to provide by rule that the 1-hour ozone standard will continue to 
apply to all areas notwithstanding promulgation of the 8-hour ozone 
standard; and that after the 8-hour standard has become fully 
enforceable under part D of title I of the Clean Air Act (CAA) and is 
no longer subject to further legal challenge, the 1-hour standard set 
forth in section 50.9(a) will no longer apply to an area once EPA 
determines that the area has air quality meeting the 1-hour standard.

DATES: Effective Date: This rule is effective on October 18, 2000.
    Applicability Dates: This rule applies on October 18, 2000 for all 
areas where EPA had revoked the 1-hour ozone standard except for those 
nonattainment areas with clean data listed in section III. F., Table 1 
of the preamble, and applies on January 16, 2001 for such areas listed 
in Table 1 of the preamble.

paper copies of comments and data submitted electronically, minus 
anything claimed as confidential business information) and the Response

I. Background

    The EPA promulgated a revised 8-hour ozone standard in July 1997 
\1\ (62 FR 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-hour standard--would no longer apply to areas. Several parties 
challenged EPA's revised ozone standard and EPA's revised particulate 
matter standard, which was promulgated on the same day. American 
Trucking Assoc. v. EPA, (D.C. Cir., Nos. 97-1440 and 97-1441) (ATA v. 
EPA).
---------------------------------------------------------------------------

    \1\ For both the 1-hour and 8-hour ozone standards, EPA has 
promulgated secondary standards that are identical to the primary 
standard. Because the primary and secondary standards are identical, 
EPA refers to the 1-hour and 8-hour standards in the singular. 
However, both EPA's initial rule determining that the 1-hour 
standard no longer applied and this rule reinstating the 
applicability of that standard apply for purposes of both the 
primary and secondary 1-hour ozone standards. Similarly, EPA's 
references to the 8-hour standard encompass both the primary and 
secondary 8-hour standards.

---------------------------------------------------------------------------

[[Page 45183]]

    On June 5, 1998 (63 FR 31014), July 22, 1998 (63 FR 39432), and 
June 9, 1999 (64 FR 30911), in accordance with 40 CFR 50.9(b), we 
issued final rules for many areas that were attaining the 1-hour 
standard, finding that the 1-hour ozone standard no longer applied to 
these areas. \2\ At that time, we amended the Code of Federal 
Regulations (CFR) to remove the designations and classifications that 
had applied to those areas for the 1-hour standard under sections 107, 
172 and 181 of the CAA. \3\
---------------------------------------------------------------------------

    \2\ Two of these final actions were challenged and these cases 
are currently pending. Environmental Defense Fund v. EPA, (D.C. 
Cir., No. 98-1363) (challenge to June 1998 final rule); Appalachian 
Mountain 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 did not revoke the 1-hour standard 
through these rulemakings. The 1-hour standard remains an effective 
regulatory standard under EPA's regulations. 40 CFR 50.9(a).
---------------------------------------------------------------------------

    On May 14, 1999, the Court of Appeals for the District of Columbia 
Circuit (D.C. Circuit) issued an opinion in the cases challenging EPA's 
revised ozone and particulate matter standards. ATA v. EPA, 175 F.3d 
1027 (D.C. Cir., 1999). The court questioned the constitutionality of 
the CAA authority to review and revise NAAQS, as applied in EPA's 
revision to the ozone and particulate matter NAAQS. The Court stopped 
short of finding the statutory grant of authority unconstitutional, 
instead providing EPA with an opportunity to articulate a determinate 
principle for revising the ozone and particulate matter NAAQS under the 
statute. 175 F.3d at 1034-40. The court also addressed EPA's authority 
to classify areas and to set attainment dates for a revised ozone 
standard. 175 F.3d at 1034-40. Based on language in sections 172(a) and 
181(a) of the CAA, the court concluded that EPA could only classify and 
set attainment dates for areas for purposes of any ozone NAAQS under 
the provisions of section 181(a) of the CAA, and that EPA could not 
enforce an ozone NAAQS more quickly than contemplated under the 
provisions triggered by classifications under section 181(a) nor could 
EPA enforce an ozone standard, such as the 8-hour standard, that was 
more stringent than the 1-hour standard. \4\ 175 F.3d at 1049-50. The 
court also held that EPA must consider the beneficial effects of 
tropospheric ozone in protecting against the 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 would not 
``engender costly compliance activity'' in light of the court's 
decision ``that it cannot be enforced by virtue of CAA Sec. 181(a).'' 
175 F.3d at 1057. The EPA filed a petition for rehearing with respect 
to these three aspects of the court's decision. \5\
---------------------------------------------------------------------------

    \4\ Sections 172(a) and 181(a) provide EPA with authority to 
classify areas that are designated nonattainment and to set 
attainment dates for those areas. Section 172(a) applies generally 
to any new or revised NAAQS, while section 181(a) is specific to 
certain ozone nonattainment areas.
    \5\ The court decided other issues raised by the petitioners. 
These issues were not raised on rehearing and are not relevant here.
---------------------------------------------------------------------------

    On October 25, 1999, EPA published the preamble to the proposed 
rule, ``Rescinding Findings That the 1-Hour Ozone Standard No Longer 
Applies in Certain Areas,'' (64 FR 57424), noting that the proposed 
regulatory language for part 81 would be published shortly. On November 
5, 1999, EPA published the proposed regulatory language for part 81 (64 
FR 60477). As proposed, the 1-hour ozone standard would be reinstated 
in areas where it had previously been revoked and the associated 
designations and classifications that previously applied in such areas 
with respect to the 1-hour NAAQS also would be reinstated. In today's 
final rule, EPA is taking final action to reinstate the area 
designations and classifications that applied prior to revocation. 
Throughout this final rule all references to reinstating designations 
refer to reinstating both designations and classifications as well. In 
addition, EPA proposed to amend 40 CFR 50.9(b) to provide by rule that 
the 1-hour ozone standard would continue to apply in all areas 
notwithstanding promulgation of the 8-hour standard, and that after the 
8-hour standard has become fully enforceable under part D of title I of 
the CAA and subject to no further legal challenge, the 1-hour standard 
set forth in section 50.9(a) would no longer apply to an area once EPA 
determines that the area has air quality meeting the 1-hour standard.
    On October 29, 1999, the D.C. Circuit issued an opinion addressing 
EPA's petition for rehearing. ATA v. EPA, 195 F.3d 4 (D.C. Cir. 1999). 
The three-judge panel that decided the case granted rehearing on 
limited issues regarding EPA's ability to implement a revised ozone 
standard. Both the panel and the full court denied all other aspects of 
EPA's petition for rehearing.\6\ With respect to EPA's authority to 
implement a revised 8-hour standard, the court modified its initial 
decision to provide that EPA may enforce a revised ozone NAAQS only in 
conformity with the control requirements triggered by a classification 
under section 181(a)--i.e., the provisions in subpart 2 of part D of 
title I of the CAA. 195 F.3d at 8. Judge Tatel filed a separate 
opinion, holding that the court should have deferred to EPA's 
reasonable interpretation of the implementation scheme for the revised 
NAAQS, but concurring in the majority's decision because it ``leaves 
open the possibility that EPA can enforce the new ozone NAAQS without 
conflicting with subpart 2's classifications and attainment dates.'' 
195 F.3d at 11.
---------------------------------------------------------------------------

    \6\ The full court voted 5-4 in favor of rehearing with two 
judges not participating. Since a majority vote of the active 
members of the court is needed to grant rehearing, the request for 
rehearing was denied.
---------------------------------------------------------------------------

    At the request of commenters, on December 8, 1999, EPA published a 
notice in the Federal Register (64 FR 68659) to reopen the comment 
period for the proposed rulemaking from December 1, 1999 until January 
3, 2000, thus affording the public a total of 60 days to comment on the 
proposed reinstatement action.
    On January 27, 2000, EPA filed a petition with the Supreme Court, 
seeking review of the court of appeals decision regarding the 
constitutionality of the provisions of the CAA for setting NAAQS and 
the court's decision regarding implementation of a revised ozone NAAQS. 
Other parties also sought review by the Supreme Court.\7\ The court 
granted EPA's petition on May 22, 2000.\8\
---------------------------------------------------------------------------

    \7\ The American Lung Association and the Commonwealth of 
Massachusetts and State of New Jersey also filed petitions for 
certiorari. In addition, groups led by the American Trucking 
Associations and Appalachian Power Company filed conditional cross 
petitions for certiorari.
    \8\ The court also granted the industry cross petitions 
regarding the consideration of costs in setting NAAQS on May 30, 
2000.
---------------------------------------------------------------------------

II. In Summary, What Action Is EPA Finalizing Today?

    Today, we are taking final action to rescind the findings that the 
1-hour standard no longer applies in those areas where the Agency had 
previously determined that the 1-hour standard had been attained. As a 
result, the 1-hour standard will again become applicable in nearly 
3,000 counties.
    Where the 1-hour ozone standard again becomes applicable as a 
result of this rulemaking, the attainment and nonattainment 
designations and classifications applicable to such areas prior to the 
determination of inapplicability will again apply. The designations are 
inextricably linked to the applicability of the standard and were 
removed solely because the standard no longer applied. See e.g., 
Interim Implementation Policy Statement, 61 FR 65752, 65754 (Dec. 13, 
1996) (``the designations would remain

[[Page 45184]]

in effect so long as the current 1-hour ozone NAAQS remains in 
effect''). Thus, since the only basis for removing the designations was 
the inapplicability of the 1-hour standard, area designations for the 
standard must also be reinstated upon reinstatement of the 1-hour 
standard.
    Given that the previous designations and classifications of these 
areas were based upon the 1-hour ozone standard, which will again apply 
as a result of this reinstatement action, EPA is amending the tables in 
part 81 of the CFR to identify the designation and classification of 
the area that applied prior to EPA's determinations that the 1-hour 
standard no longer applied. The regulatory language located at the end 
of this final rule amends the ozone tables in 40 CFR part 81 for each 
State and provides a list of the areas affected by this rule. A copy of 
these tables may also be viewed at the following Internet website 
address: http://www.epa.gov/ttn/oarpg. In addition, the areas are 
identified by air quality designations in the docket for this 
rulemaking at Docket No. A-99-22.
    The EPA's regulation, 40 CFR 50.9(b), provides that the 1-hour 
ozone standard would no longer apply once EPA determined that an area 
attained that standard. Today's action revises section 50.9(b) to 
indicate that the 1-hour standard remains applicable to all areas 
notwithstanding the promulgation of the 8-hour standard. Furthermore, 
today's action establishes that after the 8-hour standard has become 
fully enforceable under part D of title I of the CAA and subject to no 
further legal challenge, the 1-hour standard set forth in section 
50.9(a) will no longer apply to an area once EPA determines that the 
area has air quality meeting the 1-hour standard.
    In light of many areas' needs to quickly develop additional State 
Implementation Plan (SIP) programs in response to the actions EPA is 
finalizing today, the actions finalized today will become effective 90 
days after today's publication for most areas. However, for areas that 
were designated nonattainment prior to revocation but that currently 
have clean air quality data sufficient to support a redesignation to 
attainment, actions will not generally become applicable until 180 days 
after today's publication.\9\ This additional time will allow areas to 
submit redesignation requests and, if they do so, for EPA to take 
appropriate rulemaking action on such requests prior to the 
applicability date of this rule for the area.
---------------------------------------------------------------------------

    \9\ The EPA notes that in the proposal for this action, EPA 
proposed to make the final reinstatement effective after 90 days for 
all areas, and specifically requested comment on this issue. Certain 
commenters requested a longer delay in the effective date of the 
rule, and EPA has agreed that for areas with clean data that were 
previously designated nonattainment a longer period would be 
appropriate. However, ``effective date'' is a term of art relating 
to when rules published in the Federal Register will be incorporated 
in the Code of Federal Regulations, and Office of Federal Register 
requirements do not allow varying effective dates for entries in a 
table. Therefore, this action as a whole will become effective for 
all areas 90 days after publication. However, EPA will use the term 
``applicability date'' in the rule to describe the date on which the 
reinstatement of the 1-hour standard will begin to apply to an area. 
That date will generally be 180 days after publication for those 
areas with clean data previously designated nonattainment, as listed 
in Table 1 of the preamble. In addition, if States are able to 
submit redesignation requests and EPA is able to process such 
requests to the point of final action prior to 180 days from 
publication, the final action approving the redesignation may 
provide that the applicability date of the reinstatement will be the 
same date as the effective date of the redesignation approval, so 
that the redesignations may take effect in a timely manner.
---------------------------------------------------------------------------

III. What Major Comments Were Submitted on the Proposed Rule and 
What Are EPA's Responses to Such Comments?

    In our October 25, 1999 proposal, we solicited comment on whether 
EPA should rescind findings that the 1-hour ozone standard no longer 
applies in certain areas, and if EPA acted to rescind the 1-hour ozone 
standard, what the effects of a rescission would be. In section IV of 
the proposal, EPA specifically requested comment on the effect of the 
rescission for five types of areas: (1) Areas designated as attainment 
with no violation since revocation; (2) areas designated attainment 
(without maintenance plans) with violations since revocation; (3) areas 
designated attainment (with maintenance plans) with violations since 
revocation; (4) areas designated nonattainment with no violations since 
revocation; and (5) areas designated nonattainment with violations 
since revocation. Also, the Agency requested comment on the 
programmatic effects of reinstatement, such as the applicability of new 
source review (NSR) and conformity, as well as how to deal with 
sanction and Federal Implementation Plan (FIP) clocks that were in 
effect at the time of the revocations. A total of 72 comment letters 
were received on the proposal. Most of the commenters generally 
supported reinstating the 1-hour standard; however, they voiced 
individual preferences as to how EPA should proceed to carry out this 
action with respect to designations, planning obligations and timing. 
For each of the relevant issues, the following discussion summarizes 
EPA's proposed action, explains the approach EPA is adopting in this 
final rule and responds to the major comments received. All comments 
are addressed in the separate Response to Comments Document located in 
the docket.

A. Reinstatement of the Applicability of the 1-Hour Ozone Standard and 
the Designation and Classification That Existed for Each Area at the 
Time EPA Determined the Standard No Longer Applied

    The EPA generally proposed to reinstate the applicability of the 1-
hour standard in all areas for which EPA had taken action determining 
that the standard no longer applied. In addition, EPA proposed that the 
designation and classification for each such area would also be 
reinstated. The EPA proposed to restore areas to the same position they 
were in at the time EPA determined that the 1-hour standard no longer 
applied, i.e., that the designation and classification that applied at 
the time the 1-hour standard was revoked for an area would once again 
apply upon reinstatement.
    Comment: Several commenters believe that the Agency has no legal 
authority to rescind findings that the 1-hour ozone standard no longer 
applies in certain areas. Some commenters claim that EPA cited no 
statutory authority for its action and that none exists. At least one 
commenter contends that EPA's regulation at 40 CFR 50.9(b) does not 
provide a basis for reinstating the 1-hour standard and challenges 
EPA's statements that the basis for promulgating 40 CFR 50.9(b) was the 
existence of an enforceable 8-hour standard.
    Response: The EPA disagrees with the commenters' allegations that 
EPA has no authority to rescind its findings that the 1-hour standard 
no longer applies in certain areas. The EPA made those findings in 
accordance with its rule at 40 CFR 50.9(b), which provided that the 1-
hour standard would no longer apply once an area attained that 
standard. The EPA promulgated that regulation using its general 
rulemaking authority under section 301(a) of the CAA and thus has 
authority to revise that regulation (and to revise or repeal actions 
taken pursuant to that regulation) under that same authority. The 
changed circumstances regarding the status of the 8-hour standard 
provide ample support for EPA to take this regulatory action under 
section 301(a).
    Sections 108 and 109 of the CAA provide for the promulgation or 
revision of NAAQS on a periodic basis. However, those provisions are 
silent regarding how areas should transition

[[Page 45185]]

from implementation of one NAAQS for a pollutant to a revised, more 
stringent NAAQS for the same pollutant.\10\ Where, as in the rule 
promulgating the revised 8-hour NAAQS, EPA determines not to retain the 
pre-existing standard as an independent NAAQS, EPA must determine how 
areas should transition away from the pre-existing NAAQS. Since the CAA 
does not include specific provisions addressing this transition, EPA 
relied on its general rulemaking authority under section 301(a) of the 
CAA. See 62 FR 38894, July 18, 1997. Section 301(a) provides that the 
Agency has authority ``to prescribe such regulations as are necessary 
to carry out'' its functions under the CAA. In general, the statutory 
authority for promulgating a regulation also provides authority for an 
Agency to revise that regulation. The EPA is relying on its general 
rulemaking authority under section 301(a) to rescind the findings that 
the 1-hour standard no longer applies.
---------------------------------------------------------------------------

    \10\ Section 172(e) provides guidance for transitioning from a 
more stringent NAAQS for a pollutant to a less stringent NAAQS for 
the same pollutant.
---------------------------------------------------------------------------

    The present circumstances provide ample support for EPA to take 
this action rescinding its earlier determinations. The EPA promulgated 
40 CFR 50.9(b) based on the existence of an implementable 8-hour 
standard. In promulgating a revised 8-hour standard, EPA determined 
that it did not need to retain a separate 1-hour standard in order to 
protect the public health with an adequate margin of safety and to 
protect public welfare (62 FR 38863, July 18, 1997). Thus, EPA needed 
to consider how to transition away from the existing 1-hour standard to 
the revised 8-hour standard. See e.g., Proposed Interim Implementation 
Policy, (61 FR 65752, December 13, 1996). In the final rule 
promulgating the revised 8-hour standard, EPA concluded that Congress 
intended areas to remain subject to the planning requirements of 
subpart 2 \11\ of the CAA for as long as they continued to have air 
quality not meeting the 1-hour standard. In order to facilitate the 
continued applicability of subpart 2 to areas that had not yet met that 
standard, EPA determined to delay removal of the 1-hour standard from 
its regulations by promulgating 40 CFR 50.9(b). It is clear from the 
context of the rule and the statements in the preamble to the final 8-
hour NAAQS rule that the decision to find that the 1-hour standard no 
longer applied was based on the existence of an enforceable 8-hour 
standard that was protective of public health and welfare, such that 
the 1-hour standard would no longer be necessary to protect public 
health and welfare. (62 FR 38873, July 18, 1997.)
---------------------------------------------------------------------------

    \11\ Subpart 2 of part D of title 1 provides detailed 
requirements for certain ozone nonattainment areas. These provisions 
were enacted in 1990 in response to the States' continued failure to 
meet the ozone standard. Rather than providing continued flexibility 
and a one-size-fits-all approach, Congress created a tiered planning 
scheme that provided more and tougher requirements for areas with 
significant ozone problems, but also provided more time for these 
areas to meet the standards.
---------------------------------------------------------------------------

    However, because the court decision has raised doubts about the 
enforceability of the 8-hour standard and EPA's ability to implement 
the standard fully at this time, the basis for the regulation revoking 
the applicability of the 1-hour standard in certain areas no longer 
exists. Contrary to what EPA believed would occur at the time it 
promulgated 40 CFR 50.9(b), generally areas are not currently moving 
forward to implement the 8-hour standard due to the uncertainty created 
by the litigation over the ozone NAAQS. Thus, EPA believes that it is 
necessary at this time to retain the 1-hour standard in all areas to 
protect public health and welfare at least until the status of the 8-
hour standard and any issues concerning its enforceability have been 
fully resolved.\12\
---------------------------------------------------------------------------

    \12\ The fact that EPA's regulation at 40 CFR 50.9(b) does not 
reference the 8-hour standard is not controlling for determining the 
underlying basis for EPA's promulgation of that regulation. The fact 
that 50.9(b) was promulgated simultaneous with the 8-hour standard 
and placed in the subchapter of the CFR governing NAAQS is 
sufficient evidence that Sec. 50.9(b) was premised on the existence 
of the 8-hour ozone standard. Furthermore, it is clear from the 
preamble that EPA believed that the 8-hour standard would be 
enforceable, (62 FR 38856, July 18, 1997).
---------------------------------------------------------------------------

    Comment: Some commenters believe that the proposed action to 
reinstate the 1-hour ozone standard constitutes promulgation of a new 
or revised NAAQS under section 109 of the CAA and that the action is 
therefore subject to a public hearing under section 307(d). Other 
commenters contend that EPA must or should vacate the 8-hour standard 
before EPA can reinstate the applicability of the 1-hour standard. 
These and other commenters contend that section 109 contemplates only a 
single air quality standard for a particular pollutant in any given 
area and, therefore, object to having dual standards apply. They also 
claim that the existence of two ozone standards is confusing.
    Response: The EPA does not believe that the action to reinstate the 
1-hour standard constitutes the promulgation of a new or revised NAAQS 
under section 109 of the CAA. The 1-hour standard EPA is reinstating 
today is the same 1-hour standard that has been in existence since its 
original promulgation on February 8, 1979 and that continues to be a 
part of EPA's regulations at 40 CFR 50.10, (44 FR 8202). The EPA is not 
revising that standard in any way. The EPA is merely reinstating the 
applicability of that standard in certain areas. Unlike a regulatory 
action promulgating a new or revised NAAQS, this rulemaking is not 
concerned with selecting the appropriate level or form of ozone 
standards requisite to protect public health and welfare. The 
particular processes specified in sections 108 and 109, requiring the 
development of detailed scientific assessments and consultation with 
science advisory boards, are not implicated by this action. The EPA 
undertook those processes when it promulgated the 1-hour standard in 
1979. This action does not purport to revise or re-promulgate that 
standard; it only specifies the applicability of the existing 1-hour 
standard, which is specified in section 50.10, to certain areas.
    Because this action rescinding a previous regulatory determination 
and revising the regulation governing the transition from the 1-hour to 
a revised 8-hour NAAQS does not constitute either an amendment or 
revision to either the 1-hour or the 8-hour ozone NAAQS, EPA disagrees 
with the commenters that the procedural provisions in section 307(d) 
are triggered by section 307(d)(1)(A) (requiring compliance with 
section 307(d) for all rules promulgating or revising any NAAQS). Since 
the administrative requirements of section 307(d) do not apply, EPA has 
complied with the public notice and comment process specified under the 
Administrative Procedure Act, 5 U.S.C. 553, which does not require the 
Agency to hold a public hearing.
    Nor does EPA agree that the proper approach is to vacate the 8-hour 
standard. In the ATA decision, the D.C. Circuit did not dispute the 
public-health basis for the NAAQS and did not vacate the 8-hour 
standard. The EPA sees no reason to take such an action on its own. The 
EPA has filed with the Supreme Court a petition for review of the D.C. 
Circuit's decision. The EPA sees no need to vacate the 8-hour standard 
for the purpose of revising the transition scheme from the 1-hour 
standard to the 8-hour standard. Because the CAA does not provide how 
EPA must transition from one standard for a pollutant to a revised, 
more stringent standard for that same pollutant, EPA continues to 
believe it has authority to establish and to revise the appropriate 
transition scheme. Due to the uncertainty created

[[Page 45186]]

by the court's opinion, EPA believes it is a reasonable exercise of its 
authority to revise the transition scheme by reinstating the 
applicability of the 1-hour standard and the associated designations 
and classifications. For these reasons, EPA does not agree that it must 
vacate the 8-hour standard in order to reinstate the applicability of 
the 1-hour standard.
    To the extent the commenters are concerned about the existence of 
two NAAQS for the same pollutant, EPA made the decision in the 1997 
NAAQS rulemaking by determining to retain the 1-hour standard until 
areas met that standard. As provided above, EPA is not taking action to 
revise or promulgate a revised NAAQS in this rule and is not re-opening 
its previous decision that the statute allows the applicability of more 
than one NAAQS for a pollutant, such as ozone.
    Comment: Some commenters claim that EPA cannot restore the 
designation for areas except through one of the designation processes 
provided under section 107 of the CAA. Some commenters contend that EPA 
should treat these designations as initial designations under section 
107(d)(1) and that EPA should provide time for Governors to make 
recommendations before EPA may designate areas. Other commenters 
contend that EPA must use the redesignation provisions under section 
107(d)(3). Under that provision, they contend, EPA must notify the 
Governor first of its intent to redesignate and then must rely on 
current air quality data.\13\ Some of these commenters agree with EPA 
that the designation in place at the time EPA revoked the standard 
should be put back into place. Other commenters suggest that EPA cannot 
consider air quality data from the period when the standard did not 
apply and that EPA should reinstate designations based on air quality 
data from the period after the standard is reinstated.
---------------------------------------------------------------------------

    \13\ Other commenters, without referencing any specific 
statutory authority, also claim that EPA should use current air 
quality data to designate areas.
---------------------------------------------------------------------------

    Response: The EPA does not believe it needs to go through the 
procedures of section 107 of the CAA to reestablish the designations 
that were in place prior to revocation of the 1-hour standard. In this 
action, EPA is reversing its revocation of the standard because the 
recent court decision has called into question the underlying bases for 
that action. In the revocation action, EPA did not change an area's 
designation for the 1-hour standard, but determined that since the 1-
hour standard no longer applied to an area, the designation associated 
with that standard also no longer applied.\14\
---------------------------------------------------------------------------

    \14\ In revoking the standard, EPA did not redesignate areas 
pursuant to section 107 and did not require areas to meet the 
redesignation requirements of section 107(d)(3)(E), such as 
development of a maintenance plan. In fact, EPA has been challenged 
on two of the revocation rules for not following, and not requiring 
States to follow, redesignation procedures. Environmental Defense 
Fund v. EPA, (D.C. Cir., No. 98-1363); Appalachian Mountain Club v. 
EPA, (1st Cir., No. 99-1880).
---------------------------------------------------------------------------

    As explained above, EPA's action today is not the promulgation of 
new or revised NAAQS. Therefore, the initial designation provisions in 
section 107(d)(1), which apply only upon promulgation of a new or 
revised NAAQS, do not apply.
    Nor is EPA redesignating areas for purposes of the 1-hour standard. 
These areas currently do not have in place a designation for the 1-hour 
standard. The provisions in section 107(d)(3), which apply only to 
redesignations from attainment or unclassifiable to nonattainment or 
from nonattainment to attainment simply do not apply where, as here, 
there is not a current designation in place for a standard.
    The EPA's primary action through this action is to reinstate the 
applicability of the 1-hour standard. At the time EPA promulgated 40 
CFR 50.9(b), it determined that the designations should follow the 
applicability of the 1-hour standard and that the current designation 
was inextricably linked with the applicability of the 1-hour standard. 
Therefore, just as EPA determined that an area's designation no longer 
applied once the 1-hour standard on which it was based no longer 
applied, the reinstatement of the 1-hour standard necessarily brings 
back the applicability of the designation. Similarly, as EPA relied on 
its general rulemaking authority to revoke the standard and thus the 
area's designation, EPA is relying on that same authority to reverse 
the action taken in its earlier rule. Once areas have a designation for 
the 1-hour standard in place, EPA may redesignate those areas if they 
meet the requirements of section 107(d)(3)(E). As discussed in section 
III.F, below, EPA will consider redesignating those areas that have 
clean air quality data based on the three most recent years of data and 
that submit a redesignation request meeting the requirements of section 
107(d)(3)(E).
    Finally, some commenters suggest that EPA is prohibited from 
considering air quality data that became available after EPA revoked 
the standard. The EPA disagrees with this comment. Because EPA is 
reinstating the designations that existed at the time EPA revoked the 
standard, this rulemaking does not reflect more recent air quality 
data. However, in future actions to redesignate areas, EPA intends to 
consider all relevant air quality data including data that became 
available during the revocation. To the extent these commenters 
continue to have concerns about this issue, they can raise them in any 
future rulemaking action EPA may take to redesignate an area on the 
basis of that data.
    Comment: A few commenters stated that we cannot rely on the 
argument that the 8-hour standard cannot be enforced as the basis for 
revocation since this is not supported by the Court's October 29, 1999, 
decision on rehearing. In the October 29 opinion, the Court retracted 
its earlier conclusion that ``the 8-hour standard cannot be enforced,'' 
providing instead that the 8-hour standard ``can be enforced only in 
conformity with subpart 2'' of part D of title I of the CAA. Compare 
175 F.3d at 1057 with 195 F.3d at 10. Some commenters also suggest that 
it is too late for us to reconsider the revocations and to reinstate 
the applicability of the 1-hour standard. Most commenters, however, 
support reinstatement on the basis of continued uncertainty regarding 
the 8-hour standard.
    Response: The EPA believes that the uncertainty engendered by the 
litigation surrounding the 8-hour standard justifies reinstating the 1-
hour standard. It is true, that on rehearing, the Court revised its 
original opinion to indicate that EPA can enforce the 8-hour standard 
in conformity with subpart 2 of the CAA. However, in that same 
sentence, the Court provided that it was remanding the 8-hour standard. 
The Court did not vacate the 8-hour standard because ``the parties have 
not shown that the standard is likely to engender costly compliance 
activities.'' As the petitions for certiorari before the Supreme Court 
demonstrate, there continues to be uncertainty regarding when the 
standard could be implemented in light of the ongoing litigation.\15\ 
Because of the continuing litigation and the differing views of the 
many parties to the litigation, EPA is not currently taking any action 
that could be construed as inconsistent with the

[[Page 45187]]

Court's decision.\16\ In light of the continuing uncertainty regarding 
EPA's authority to implement the 8-hour standard, EPA believes it is 
prudent to reinstate the 1-hour standard to ensure public health 
protection from ozone.
---------------------------------------------------------------------------

    \15\ In addition to EPA, two other parties have requested that 
the Supreme Court review portions of the D.C. Circuit's decision 
regarding the ozone and particulate matter NAAQS. Other parties have 
opposed Supreme Court review of the implementation issues. In their 
papers before the Court, several of these parties have suggested 
that EPA is barred from enforcing the more stringent 8-hour NAAQS, 
while others raise concerns that the Court's opinion is unclear 
regarding the enforceability of the 8-hour standard.
    \16\ For example, EPA has stayed the applicability of its final 
regulatory determinations under section 126 of the CAA to the extent 
they were based on the 8-hour NAAQS. (65 FR 2674, January 17, 2000). 
Similarly, EPA recently proposed to stay the 8-hour basis of its 
NOX SIP call rule, which calls on 22 States and the 
District of Columbia to reduce emissions of nitrogen oxides that 
contribute to ozone problems in other States. (65 FR 11024, March 1, 
2000).
---------------------------------------------------------------------------

    Contrary to the suggestions of some commenters, EPA does not 
believe it is too late to rescind the revocations of the 1-hour 
standard. The commenter does not cite and EPA is unaware of any 
limitation on when an Agency may change a regulation based on new 
information. The EPA acted quickly in response to the uncertainty 
raised by the Court's decision, proposing action only 5 months after 
the original decision by the court. During that time, EPA was assessing 
the impacts of the opinion on implementation of the 8-hour standard, 
determining options for rehearing and appeal, and developing the 
proposed rule to rescind the revocations of the 1-hour standard. Based 
on requests for an extension of the comment period, EPA provided a 
comment period of 60 days on this action. Thus, EPA is acting in a 
timely fashion by issuing this rule approximately a year afer the court 
issued its original decision.
    Comment: A few commenters suggested that EPA was proposing to 
reinstate the standard in too many areas. One set of commenters noted 
that EPA's goal of providing protection in areas now violating the 1-
hour standard could be accomplished by reinstating the standard only in 
those areas that were violating the 1-hour standard. Other commenters 
suggested that we not reinstate the 1-hour standard in States that have 
adopted the 8-hour standard or where the most recent data for an area 
indicate that it would be designated attainment for the 8-hour 
standard. These commenters are concerned that resources will be wasted 
on meeting the 1-hour standard rather than the more protective 8-hour 
standard.
    Response: The EPA determined that it is critical to have a fully 
enforceable standard for ozone in each area of the country in order to 
protect the public health and welfare and to minimize public confusion. 
The EPA believes that it is important to have a fully-implementable 
ozone standard in place in order to ensure adequate protection of 
public health. A fully enforceable 1-hour standard will ensure that 
sufficient control measures remain in place to prevent violations in 
areas attaining the standard and to continue improvements in air 
quality in areas not attaining the standard. The options presented by 
the commenters would not result in the applicability of a fully-
enforceable ozone standard and thus could erode public health 
protection for people living and working in areas that might violate 
the standard in coming ozone seasons.
    With respect to those commenters that suggest that EPA not 
reinstate the standard in areas that have adopted the 8-hour standard, 
EPA is concerned, in light of the ATA decision, that it will be unable 
to enforce fully the 8-hour standard in the short term. Without a fully 
enforceable, Federal 8-hour standard, EPA does not have the ability to 
require States to implement an 8-hour standard. This is true even in 
States that may have adopted the 8-hour standard as a State rule. Since 
State adoption of the 8-hour standard does not ensure implementation 
and enforcement of that standard in conformity with Federal 
requirements for clean air, EPA believes it is necessary to reinstate 
the 1-hour standard in all areas pending resolution of litigation over 
the 8-hour NAAQS. The EPA acknowledges that it may be more efficient to 
concentrate resources on planning to implement a more protective 8-hour 
standard, but EPA lacks the ability to require States to do so at this 
time. For these reasons, EPA believes that the existence of the 8-hour 
standard does not provide the same certainty of public health 
protection as does the 1-hour standard at this time.
    Finally, with respect to the comment that EPA not reinstate for 
areas that will be designated attainment for the 8-hour standard, EPA 
has not designated any areas for the 8-hour standard. The States have 
not recommended boundaries for purposes of the 8-hour standard and EPA 
has not yet determined boundaries or designated any 8-hour areas. In 
fact, EPA guidance on the determination of boundaries was issued only 
recently. (Boundary Guidance on Air Quality Designations for the 8-Hour 
Ozone National Ambient Air Quality Standards (NAAQS or Standard), March 
28, 2000). The EPA has advised States to consider the guidance and make 
recommendations to EPA by June 30, 2000. The EPA must then respond to 
those recommendations and give States 4 months comment on its response. 
Only after this process could EPA make final designations. Given the 
many steps that must occur before EPA promulgates designations for the 
8-hour standard, EPA believes it is far too early to presume precisely 
which areas would be designated attainment for the 8-hour standard.

B. Revision to 40 CFR 50.9(b) to Provide That EPA Will Again Determine 
the 1-Hour Ozone Standard No Longer Applies to an Area Once EPA's 
Authority to Implement and Fully Enforce the 8-Hour Standard Is No 
Longer in Question

    The EPA proposed to revise 40 CFR 50.9(b) to provide that once the 
8-hour ozone standard is fully enforceable and no longer subject to 
legal challenge, the 1-hour standard will no longer apply to an area if 
EPA determines that the area has air quality meeting the 1-hour 
standard.\17\ The EPA's final rule adopts this position.
---------------------------------------------------------------------------

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

    Comment: Some commenters disagree with EPA's proposed revision to 
Sec. 50.9(b). These commenters feel that the promulgation of an 8-hour 
standard should not be the basis for revoking the applicability of the 
1-hour standard. Some of the commenters believe that removing the 
applicability of a NAAQS and associated control measures based solely 
on air quality is inconsistent with the law and that we should consider 
both the 1-hour and 8-hour ozone standards. Some commenters believe 
that future revocations should not be allowed without first following 
the redesignation process as prescribed by the CAA. Other commenters 
suggest that once the 8-hour ozone standard is enforceable, we should 
revoke the 1-hour standard everywhere regardless of what the air 
quality is. Finally, one commenter claims that EPA should not amend 
section 50.9(b) now since the 8-hour standard may never be enforceable.
    Response: The EPA believes that it has the authority upon issuance 
of a new or revised standard to determine the continued validity of the 
pre-existing standard and when, if ever, it should no longer apply. In 
the final rule promulgating the 8-hour standard, EPA determined that 
the 1-hour standard was no longer necessary to protect public health 
and welfare in light of the revised 8-hour standard, which States would 
be required to implement and enforce. However, EPA also determined that 
Congress intended areas that remained nonattainment for the 1-hour 
standard to meet the requirements of subpart 2, until the 1-hour 
standard is attained. As EPA explained in the

[[Page 45188]]

preamble to the NAAQS rule, section 109 of the CAA clearly authorizes 
EPA to promulgate revisions to a standard, which necessarily includes 
the authority to revoke previous standards that have been revised (62 
FR 38857, July 18, 1997). On the other hand, subpart 2 of the CAA sets 
out numerous requirements specifically applicable to areas not 
attaining the 1-hour ozone standard. To accommodate both of these 
provisions, EPA concluded that after promulgation of the 8-hour 
standard, subpart 2 must continue to apply as a matter of law in each 
area until the 1-hour standard is attained (62 FR 38873). Thus, to 
facilitate continued applicability of the subpart 2 requirements, EPA 
established a transition scheme in 40 CFR section 50.9(b) that provided 
the 1-hour standard would continue to apply until an area had air 
quality meeting the 1-hour standard.
    The EPA does not agree that in order to determine a pre-existing 
standard no longer applies, EPA must require areas to meet the 
requirements for redesignation and formally redesignate an area from 
nonattainment to attainment under section 107(d)(3). As a general 
matter, Congress has not specified any procedure for determining that a 
pre-existing NAAQS no longer applies once EPA promulgates a revised 
standard. Moreover, although Congress gave some guidance on how to 
transition to a less stringent NAAQS, see CAA section 172(e), it did 
not provide clear guidance on how to transition to a more stringent 
NAAQS. The EPA believes that in determining how to transition to a 
revised NAAQS, it must make common-sense decisions, considering the 
intent of Congress in light of the statutory scheme, including how best 
to ensure public health protection without imposing unduly burdensome 
requirements on States and sources.\18\
---------------------------------------------------------------------------

    \18\ EPA's scheme for transitioning to the 8-hour ozone standard 
is consistent with the Agency's approach in the one other case where 
it promulgated a more stringent NAAQS revision. See 52 FR 24672 
(July 1, 1987). When EPA revised the particulate matter standard to 
change the indicator from total suspended particulates (TSP) to 
particulate matter with a diameter of 10 microns or less (PM-10), it 
retained the TSP designations for a limited purpose because the 
statutory limitations for certain areas under the Prevention of 
Significant Deterioration (PSD) program were linked to TSP 
designations. See CAA section 163. Congress subsequently codified 
EPA's decision in section 107(d)(4)(B) of the CAA. Similarly, EPA 
here is retaining the 1-hour standard and associated designations 
for purposes of continued application of subpart 2 of the CAA, until 
the purpose of subpart 2--attainment of the 1-hour standard--is met.
---------------------------------------------------------------------------

    With respect to the transition from the 1-hour standard to the 8-
hour standard, EPA determined that Congress intended areas to remain 
subject to the 1-hour standard until such time as that standard is met. 
Since all areas of the country were subject to the revised, more 
stringent 8-hour standard, EPA determined that it did not make sense to 
require areas that had met the 1-hour standard but remained designated 
nonattainment to complete a maintenance plan since generally these 
areas would be required to develop an attainment plan for the more 
stringent 8-hour standard. The EPA continues to believe that, if a 
fully enforceable 8-hour standard were in effect, it would be 
unreasonable to require States to demonstrate that an area will 
maintain the 1-hour standard for 10 years (with a later update for a 
subsequent 10 years) when these areas would be developing attainment 
plans and, ultimately, maintenance plans for the more stringent 8-hour 
standard.
    This interpretation is consistent with the approach Congress 
employed in the one area where the statute does address revocation of a 
prior standard. Section 172(e) of the CAA provides that where EPA 
relaxes a standard, it must require all areas that have not yet 
attained the more stringent prior standard to provide for controls that 
are at least as stringent as those that applied to areas designated 
nonattainment of the prior standard. This provision both clarifies that 
Congress intended EPA to revoke standards and associated control 
requirements in certain circumstances where they have been revised, and 
that an appropriate criterion for determining when a prior standard 
should be revoked is whether or not an area has attained that standard. 
Congress did not, however, require redesignation of areas with 
development of maintenance plans prior to removal of control 
obligations. Rather, Congress required only that control measures 
continue to apply until an area has attained a prior standard and 
implicitly allows for revocation of the prior standard.
    The EPA also disagrees with the commenter who suggests that EPA 
should not amend Sec. 50.9(b) because it has been struck down by the 
court and that the 8-hour standard might never be enforceable. The EPA 
disagrees with the claim that the court struck down 40 CFR 50.9(b). The 
court did not vacate any aspect of EPA's July 1997 rulemaking, which 
included the promulgation of section 50.9(b).\19\ The EPA believes that 
its proposed revision to section 50.9(b) addresses the contingency that 
the 8-hour standard may never become enforceable. The EPA believes that 
it is better to promulgate revisions to section 50.9(b) at this time so 
that interested parties are aware of EPA's planned transition approach 
if and when the 8-hour standard becomes fully enforceable.
---------------------------------------------------------------------------

    \19\ Furthermore, no party in the ATA case challenged EPA's 
promulgation of 40 CFR 50.9(b) and the court did not address this 
regulatory provision in either its May 14, 1999 or its October 29, 
1999 decisions.
---------------------------------------------------------------------------

    Finally, for the reasons explained above, EPA believes that subpart 
2 continues to apply as a matter of law to all areas that have not yet 
attained the 1-hour standard. Therefore, EPA does not believe it has 
the authority to determine the 1-hour standard inapplicable to any area 
that has not yet attained that standard, even after the 8-hour standard 
has become fully enforceable.

C. Areas Designated as Attainment With No Violations Since Revocation

    The EPA proposed that upon reinstatement of the standard, areas 
designated as attainment with no violations after revocation would not 
be subject to any new planning requirements under subpart 2 of the CAA, 
beyond continuing compliance with any requirements in an approved 
maintenance plan. The EPA is adopting this position in today's action.
    Comment: Some commenters contend that all areas designated as 
attainment should be treated on an equal basis. The EPA should either 
require all attainment areas to have maintenance plans, including the 
obligation to comply with conformity, or free all areas from the 
maintenance plan requirement.
    Response: The EPA does not have the authority to require all areas 
designated as attainment either to have a maintenance plan or to 
relieve them of that obligation. The CAA specifically provides that 
areas seeking redesignation from nonattainment to attainment must 
develop and submit maintenance plans. Upon redesignation, these areas 
are required to continue to implement their maintenance plans, 
including complying with the conformity provisions. Areas that were 
initially designated as attainment after the 1990 CAA Amendments are 
not subject to this requirement. In addition, section 176(c)(5)(B) of 
the CAA makes clear that areas with maintenance plans continue to be 
subject to conformity and that areas that have historically been 
designated as attainment are not subject to conformity.

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

    The EPA proposed to provide areas designated attainment without

[[Page 45189]]

maintenance plans, that have had violations since revocation, a 
reasonable time to come back into attainment prior to taking action to 
designate them as nonattainment. There are only four areas which fall 
into this category: Berrien Co., MI; Hamilton Co., IN; Hamilton Co., 
TN; Rowan Co., NC.
    Comment: Several commenters asked that we define what is a 
``reasonable time frame'' to bring areas back into attainment. Some 
commenters reference measures that States have already taken to address 
ozone problems.
    Response: The CAA does not mandate that EPA redesignate areas from 
attainment to nonattainment. Rather, section 107(d)(3)(A) provides the 
general criteria that EPA may consider in determining whether to 
redesignate an area.\20\ In particular, EPA may consider air quality 
data, planning and control considerations or any other air-quality 
related considerations.
---------------------------------------------------------------------------

    \20\ For areas designated as nonattainment seeking redesignation 
to attainment, section 107(d)(3)(E) sets forth additional criteria 
that must be met before EPA may redesignate the area.
---------------------------------------------------------------------------

    The Agency commends areas for any initiatives they may have taken, 
such as voluntary emission reduction programs, to help improve air 
quality. The EPA will consider this information in determining whether 
and when to move forward with a redesignation to nonattainment. States 
should work with the appropriate EPA Regional Offices to determine 
whether additional measures are necessary to address a recent 
violation.
    To the extent additional measures are needed, EPA believes that it 
is reasonable for States to adopt measures to address any violations 
within 6-9 months of the effective date of this final action. The EPA 
is recommending 6-9 months as the presumptive period for action, 
however, each State should work with the relevant EPA Regional Office 
to develop a strategy for specific areas. States have been on notice of 
EPA's planned reinstatement of the standard and should have begun an 
analysis of measures to address any violation. In addition, since 
reinstatement for these areas will not be effective until 90 days after 
publication of this final action in the Federal Register, this approach 
will allow States 9-12 months from promulgation of this final rule to 
adopt any necessary measures and well over a year from the time of 
EPA's proposal to reinstate the standard. The EPA believes that this 
period is comparable to the 1-year time period provided under section 
179(d) for States to adopt measures based on a finding that the State 
failed to attain the standard.

E. Areas Designated Attainment (With Maintenance Plans) With Violations 
Since Revocation

    For areas designated attainment with maintenance plans and with 
violations since revocation, EPA proposed that the contingency measures 
in the area's approved SIP should be implemented to address any 
violations of the 1-hour ozone standard. If a State had removed any 
contingency measures after EPA determined the 1-hour standard no longer 
applied, EPA proposed the State should place the contingency measure 
back into the SIP. There are seven areas which fall into this category: 
Charlotte-Gastonia, NC; Huntington-Ashland, WV-KY; Knoxville, TN; 
Nashville, TN; Portland-Vancouver Air Quality Management Area, OR-WA; 
Richmond, VA; Sheboygan, WI.
    Comment: Several commenters question whether it is appropriate to 
require States to implement contingency measures and question whether 
contingency measures will provide any real air quality benefits. They 
disagree that automatic implementation of such measures is the correct 
solution to addressing the current air quality problem. Some commenters 
believe that since the 1-hour standard did not apply in the areas after 
revocation, the areas cannot be considered to be violating the 1-hour 
standard based on data from that time; thus in their view, violations 
that occurred after revocation but prior to reinstatement cannot 
trigger contingency measures. Some commenters argue that even if a 
violation occurred during the period in which the standard was revoked, 
the most recent 3 years of air quality data should have precedence. 
They state that if those data indicate the area is not violating the 
standard, the State should not be required to implement contingency 
measures.
    In addition, some commenters were concerned that the schedule 
specified in the SIPs for implementation of contingency measures is 
often triggered as of the date of the violation. Thus, under these 
SIPs, some portion of the implementation period may already have passed 
by the time the reinstatement becomes effective.
    Other commenters claim that EPA should use its authority under 
section 110(k)(6) to place deleted contingency measures back into the 
SIP. Section 110(k)(6) provides that EPA may revise its prior approval 
removing the contingency measures if it determines that the approval 
action was in error.
    Response: Section 175A(d) of the CAA requires that a maintenance 
plan include such contingency measures as are necessary to promptly 
correct any violation of the NAAQS that occurs after redesignation of 
the area. The EPA believes that areas designated as attainment that 
have maintenance plans in place and that have had violations of the 
NAAQS since revocation, are required by the CAA and by their approved 
SIPs to move forward to implement contingency measures. Since the 
purpose of these measures is to protect public health, EPA believes it 
is appropriate to require areas to implement contingency measures to 
ensure that future air quality will meet or be lower than the NAAQS.
    The EPA has allowed States a great deal of flexibility with respect 
to contingency measures. First, EPA has allowed flexibility in terms of 
the selection and adoption of contingency measures for the maintenance 
plan. The EPA does not require that contingency measures be fully 
adopted in order for the maintenance plan to be approved. The 
maintenance plan need only ensure that the contingency measures be 
adopted expeditiously once they are triggered. (Procedures for 
Processing Requests to Redesignate Areas to Attainment, September 4, 
1992, John Calcagni).
    In addition, when an area violates the standard, States have 
discretion in selecting which of the contingency measures in the 
approved maintenance plan should be implemented. In the past, EPA has 
allowed States to substitute and implement new, more appropriate and 
effective contingency measures. (64 FR 28753 and 64 FR 28757, May 27, 
1999). The EPA would allow States with areas violating the standard to 
do so here through the SIP process, if substitution of measures would 
not unreasonably delay air quality benefits. Therefore, if, as at least 
one commenter suggests, existing, approved contingency measures may no 
longer be appropriate or effective, the State may seek a substitution. 
However, the fact that existing contingency measures may not be 
effective or appropriate does not support a decision not to require 
implementation of contingency measures to address the air quality 
problem.
    Finally, although EPA has indicated that it would provide a 
reasonable period of time for violating attainment areas without 
maintenance plans to correct their air quality problem before 
designating them to nonattainment, EPA does not believe it has the 
ability to delay the triggering of the States' obligation to select and 
adopt contingency measures for areas with maintenance plans that are 
experiencing violations. The CAA contemplates that

[[Page 45190]]

contingency measures will be implemented ``promptly'' in such areas. In 
addition, the terms of the maintenance plans themselves require 
adoption and implementation of contingency measures upon violations. 
Thus, the CAA requires areas to adopt appropriate contingency measures 
once violations occur. States may submit SIP revisions to substitute 
appropriate measures at any time.
    The EPA disagrees that violations are not valid if they occurred 
during the period when the 1-hour standard did not apply for an area. 
The fact that an air quality standard does not apply during a period of 
time does not invalidate air quality data gathered at that time or 
invalidate the exceedances or violations demonstrated by that data. In 
fact, the statutory period for initial designations belies that 
interpretation. Under section 107(d)(1), Governors must recommend 
designations within 1-year of promulgation of a standard and EPA must 
designate areas within 2 years of promulgation. For standards that are 
measured over a period of longer than 2 years, such as the 1-hour and 
8-hour ozone standards, EPA would necessarily be required to consider 
monitoring data that preceded promulgation of the standard in making 
designations. In addition, the State and sources are not unreasonably 
disadvantaged. The EPA is not requiring that the time for States to 
implement contingency measures runs from the time of the violation, but 
rather from the effective date of the reinstatement of the standard.
    This approach is consistent with the approach EPA is taking 
concerning tolling of applicable clocks for conformity obligations and 
sanctions. As EPA states elsewhere in this notice (sections III.I and 
III.J), EPA believes that clocks related to the timing of conformity 
determinations and sanctions should not be considered to have run 
during the period that the 1-hour standard was not applicable to an 
area. It would be unfair to areas to have such clocks expire during a 
time that the area was not subject to the planning obligations 
associated with the clocks. Thus, EPA has concluded that any such 
clocks would be tolled during the time the standard was not applicable. 
When this rule becomes applicable, the clock will begin to run again 
based on whatever time remained when EPA revoked the standard for an 
area. Similarly, EPA believes that the duty to implement contingency 
measures should be triggered on the effective date of this 
reinstatement action rather than the date of any past violation.
    If an area has a SIP in which the timing for contingency measures 
is triggered on the date of the violation, EPA believes that it would 
be appropriate to interpret the violation as occurring on the effective 
date of the reinstatement. If States still remain concerned about the 
approved language in existing SIPS regarding the timing for triggering 
contingency measures, they should work with the relevant EPA Regional 
Office to determine an appropriate manner to address the issue. Since 
the 1-hour standard was not in effect for the area during the 
revocation period, EPA does not believe that the area should be subject 
to a shorter time than contemplated in the State's adoption and EPA's 
approval of the SIP.
    With respect to commenters that claim that an area may have had a 
violation (during 1996-1998) and once again is attaining (during 1997-
1999), EPA believes that such areas should work with the relevant EPA 
Regional Office to determine an appropriate course of action. If there 
are additional control measures that applied during 1999, but did not 
apply during the period of the violation, it may not be necessary to 
implement further contingency measures at this time.
    The EPA allowed States to remove contingency measures from approved 
SIPs where they were linked to the 1-hour standard or air quality ozone 
concentrations and EPA had taken action to determine that the 1-hour 
standard no longer applied. See ``Guidance for Implementing the 1-Hour 
Ozone and Pre-Existing PM10 NAAQS,'' from Richard D. Wilson, Acting 
Assistant Administrator for Air and Radiation, December 29, 1997. The 
EPA believed that such revisions would be consistent with section 
110(l) of the CAA since EPA was determining that the 1-hour standard no 
longer applied and, therefore, removal of the contingency measures 
would not interfere with any applicable requirement concerning 
attainment and reasonable progress, or any other applicable requirement 
of the CAA. Id.
    Because EPA believes it is now appropriate and necessary to 
reinstate the 1-hour standard, EPA believes it is no longer appropriate 
for States not to have those contingency measures in the approved SIP. 
States will need to move forward to put contingency measures back into 
the SIP. The EPA believes that States should have some discretion in 
selecting these contingency measures considering what measures would be 
appropriate, and adopting such measures, as necessary. Thus, at this 
time, EPA is not moving forward to use section 110(k)(6) to retract its 
earlier approval of SIP revisions removing contingency measures. Since 
EPA is not now proposing to move forward under section 110(k)(6), EPA 
is not addressing whether that provision provides the legal authority 
to take the action suggested by the commenters.

F. Areas Designated Nonattainment With No Violations Since Revocation

    For areas designated nonattainment with no violations since the 
standard was revoked in these areas, EPA proposed that the 
nonattainment designation would again apply, but recommended that the 
State submit a redesignation request that meets the requirements of 
section 107(d)(3)(E). In addition, EPA noted that its May 10, 1995, 
``Clean Data Policy'' could provide relief from some subpart 2 measures 
for these areas as long as they continued to have clean data. However, 
other subpart 2 requirements would apply unless and until an area was 
redesignated to attainment. There are 45 areas which fall into this 
category. The following table (Table I) lists the areas in this 
category:

    Comment: A number of commenters were opposed to reinstating prior 
designations and classifications, particularly in the case of areas 
that were designated nonattainment at the time of the revocation and 
that have remained clean. They want EPA to consider current monitoring 
data as the basis of an area's designation. These commenters claim that 
EPA's proposed approach creates inequities among the various types of 
areas where the standard would be reinstated. For example, they point 
to areas that will be designated attainment but that are violating the 
1-hour standard. The commenters contend that it is inequitable that 
those areas will not be subject to subpart 2 control requirements, 
including new source review and conformity, but that certain 
nonattainment areas that have remained clean since revocation will be. 
One commenter did not seem to object to this approach, but recommended 
that EPA approve pending redesignation requests within 1 to 3 months of 
the final reinstatement.
    Other commenters supported EPA's proposal to restore the 
designations and classifications that applied at the time of the 
revocation action. Several of these commenters claimed that EPA should 
not or could not consider violations that occurred while the standard 
was not applicable. Others recommended that EPA designate as 
nonattainment all areas that have current violations of the 1-hour 
standard.
    Specifically, some commenters request that EPA now designate as 
attainment areas that were designated as nonattainment and that have 
never been approved for redesignation in accordance with the criteria 
in section 107(d)(3)(E). Thus, the commenters request EPA to rely on 
its revocation action as a justification for avoiding those 
requirements.
    Response: As provided in section III.A, above, in today's action 
EPA is only reversing its earlier determination that the 1-hour 
standard no longer applies in these and other areas. Therefore, EPA is 
not considering current air quality data in establishing designations 
under this action as EPA would do when establishing initial 
designations for areas under section 107(d)(1) or redesignating areas 
under section 107(d)(3). In promulgating 40 CFR 50.9(b), EPA determined 
that the designations and classifications were linked to the 
applicability of the 1-hour standard. On that basis, in applying 
section 50.9(b), EPA removed not just the applicability of the 1-hour 
standard, but also the associated designation and classification for 
the 1-hour standard. Because EPA is rescinding its prior findings 
concerning the applicability of the 1-hour standard, the designations 
and classifications that accompanied that standard at the time of 
revocation come back into place with the standard.
    The EPA disagrees with the commenters as a matter of law and 
policy. It is clear from the CAA, as amended in 1990, that Congress 
intended areas to meet specific criteria for redesignation with respect 
to an existing, applicable NAAQS. As discussed above in section III.A & 
B, EPA believes it was appropriate to transition from the 1-hour ozone 
standard to the 8-hour ozone NAAQS by requiring only that areas attain 
the 1-hour standard--one of the five criteria \21\ for redesignation. 
However, EPA believes it would circumvent Congressional intent to 
reinstate the 1-hour standard because of the uncertainty surrounding 
the 8-hour standard and permit areas effectively to be redesignated 
from nonattainment to attainment without meeting the other four 
redesignation criteria. The EPA does not believe that it can rely on 
its rule determining the 1-hour standard no longer applies, the basis 
for which has been undermined by the ATA decision, as support for 
sidestepping the redesignation criteria.
---------------------------------------------------------------------------

    \21\ Section 107(d)(3)(E) provides that EPA may not redesignate 
an area from nonattainment to attainment unless EPA: (1) determines 
that the area has attained the relevant NAAQS; (2) has fully 
approved the area's SIP; (3) determines that the improvement in air 
quality is due to permanent and enforceable reductions in emissions; 
(4) has fully approved a maintenance plan for the area; and (5) has 
determined that the State has met all of the applicable SIP planning 
requirements.
---------------------------------------------------------------------------

    Moreover, because EPA cannot be sure how long it will take to 
resolve the issues surrounding the 8-hour standard, EPA believes that 
it is important to ensure that areas will maintain the 1-hour standard. 
The statutory redesignation criteria are designed to accomplish that 
goal. Thus, EPA believes it is essential that they be met.
    However, EPA believes that it is appropriate to provide additional 
time to nonattainment areas with clean air quality data since 
revocation in order to complete the redesignation process. Therefore, 
EPA is taking final action today to delay the applicability date of the 
final rule for up to 180 days for areas that were designated 
nonattainment at the time of revocation and continue to have clean 
data, in order to allow States to submit redesignation requests and EPA 
time to act on them prior to the applicability date. These areas are 
identified in Table 1. In the proposed action to reinstate the 
standard, EPA recommended that areas begin to develop redesignation 
requests (or revise, as necessary, any existing requests) so that EPA 
could move forward quickly to approve the requests upon reinstatement. 
The EPA understands that some States are now ready, or close to being 
ready, to submit these requests to EPA. If requests are submitted 
within the next 2 months, EPA believes it can complete action on them 
before this rule becomes applicable. The EPA will work with States to 
ensure that review of redesignation requests occurs expeditiously. In 
addition, if States are able to submit redesignation requests and EPA 
is able to process such requests to the point of final action prior to 
180 days from publication, the final action approving the redesignation 
may provide that the applicability date of the reinstatement will be 
the same date as the effective date of the redesignation approval, so 
that the redesignations will occur simultaneously with the 
reinstatement.
    Once EPA approves a redesignation request, an area would be subject 
to the requirements of the approved maintenance plans. Redesignation to 
attainment does not relieve an area of its conformity obligations.
    With respect to all of the areas previously designated 
nonattainment which currently have clean air quality data, as listed in 
Table 1, EPA concluded at the time of revocation that these areas had 
clean air quality data. These findings remain applicable unless

[[Page 45192]]

more recent air quality data indicates that a violation has occurred. 
The EPA intends to complete rulemaking prior to the applicability date 
of this rule to determine the eligibility of these areas to use EPA's 
May 10, 1995 clean data policy. (Reasonable Further Progress, 
Attainment Demonstration, and Related Requirements for Ozone 
Nonattainment Areas Meeting the Ozone National Ambient Air Quality 
Standard, John S. Seitz).
    The EPA acknowledges that reinstating the designations as they were 
prior to revocation arguably may produce some inequities among areas; 
however, these potential inequities are inherent in the redesignation 
process set forth in section 107. As provided in section III.D, above, 
Congress provided EPA with discretion in determining whether to 
redesignate areas from attainment to nonattainment and specified 
factors for EPA to consider. In comparison, Congress prohibited EPA 
from redesignating an area from nonattainment to attainment unless EPA 
determined that the area meets five specific criteria. In addition, any 
redesignation must occur through notice-and-comment rulemaking. Thus, 
at any point in time, an area can be attaining the standard, yet still 
be designated nonattainment, or designated attainment and be violating 
the standard, including the period while rulemaking to effect a 
redesignation is proceeding.\22\
---------------------------------------------------------------------------

    \22\ One court, in an unpublished opinion, upheld EPA's 
interpretation of the redesignation provisions of the CAA that an 
area must attain the standard and remain in attainment during the 
time that a redesignation request is pending in order to qualify for 
redesignation. Commonwealth of Kentucky, et al. v. US EPA, No. 96-
4274 (6th Cir. Sept. 2, 1998).
---------------------------------------------------------------------------

    Areas where EPA is today reinstating the applicability of the 1-
hour standard will be placed back into the same position they were in 
prior to revocation. The EPA does not believe that this creates any 
additional inequities for these areas. It is true that EPA had 
previously relieved areas of the obligation to develop a maintenance 
plan for the 1-hour standard since they were to begin implementing the 
8-hour standard. However, since it is now uncertain when areas will be 
required to implement the 8-hour standard, EPA does not believe it is 
inequitable to require these areas, as any other area, to develop 
maintenance plans prior to redesignating them to attainment.
    Comment: A few commenters made requests that specific types of 
areas not be designated nonattainment. One commenter suggested that EPA 
should designate as attainment areas that were previously designated 
marginal or rural transport areas and that are clean without requiring 
redesignation. A few commenters suggested that EPA not penalize areas 
with violations where the cause of the violations is clearly one of 
transport and dislike the ``unfair'' label of nonattainment.
    Response: For the reasons provided above, EPA does not see a legal 
avenue for changing the designation of marginal or rural nonattainment 
areas or areas affected by transport based solely on the reinstatement 
of the standard. Nor do the commenters identify a legal mechanism for 
treating these areas differently from other nonattainment areas with 
clean data.\23\ Some commenters set forth conflicting arguments, 
arguing that EPA should generally establish the designations that were 
in place at the time of the revocation while simultaneously claiming 
that certain types of areas should be designated based on current air 
quality. The EPA does not see how it can reconcile these conflicting 
positions. As provided above, EPA believes the only proper 
interpretation of this reinstatement action is that prior actions are 
reversed such that prior designations are put back into place. The EPA 
will consider current air quality data in determining whether to 
redesignate areas under section 107(d)(3).
---------------------------------------------------------------------------

    \23\ One commenter suggests that we could do so as we did in 
revoking the standard. However, that was not a case of simply 
telling areas that they did not need to submit maintenance plans 
notwithstanding their nonattainment designation. It was a case of 
telling areas that they were no longer subject to any obligations 
with respect to the 1-hour standard based on expected implementation 
of the 8-hour standard, which would no longer be the case for 
marginal or rural nonattainment areas or areas affected by transport 
where the 1-hour standard is reinstated.
---------------------------------------------------------------------------

    In addition, EPA already has provided relief to areas subject to 
transport in a number of ways. Such areas may continue to take 
advantage of appropriate EPA policy relating to areas affected by 
transport.\24\ In addition, EPA has issued final rules requiring States 
or sources to address transported NOX and ozone in 
accordance with section 110(a)(2)(D) of the CAA. Final NOX 
SIP Call Rule (63 FR 57356, October 27, 1998); Final Rule on Section 
126 Petitions (64 FR 28250, May 25, 1999). Areas affected by transport 
will benefit from these rules.
---------------------------------------------------------------------------

    \24\ E.g.,``Extension of Attainment Dates for Downwind Transport 
Areas,'' from Richard Wilson, Acting Assistant Administrator for Air 
and Radiation, dated July 16, 1998, published at 64 FR 14441, March 
25, 1999.
---------------------------------------------------------------------------

    Comment: Some commenters were concerned about redesignation 
requests and maintenance plans submitted prior to the time that EPA 
determined that the 1-hour standard no longer applied. These commenters 
thought that it would be unfair for EPA to require the areas to update 
the maintenance plan to provide maintenance for 10 years from the time 
of EPA's approval.
    Response: The EPA appreciates the concerns of those few areas that 
may have had pending redesignation requests that demonstrate continued 
maintenance for some period shorter than 10 years from the time of 
EPA's final action, due to the passage of time. In such areas, EPA will 
work with those States and respective transportation agencies to 
develop technically sound future budgets. Such future emissions 
projections will consider growth for existing and future sources, 
forecasting for vehicle miles traveled, other federally mandated 
programs, particularly the more recent mobile fuels rules and other 
applicable measures; the resulting budgets will undergo normal public 
process review. The EPA will work with the affected areas on an 
individual basis to determine the extent to which additional 
maintenance demonstrations may be needed to support redesignation, and 
will take appropriate final action on maintenance demonstrations in 
connection with future action on pending redesignation requests.

G. Areas Designated Nonattainment With Violations Since Revocation

    For areas designated nonattainment with violations since the 
standard was revoked in those areas, EPA proposed that the 
nonattainment designation would again apply and that the area would be 
subject to the subpart 2 requirements once the reinstatement became 
effective. The EPA proposed that these areas have a reasonable time to 
meet the applicable planning requirements and that EPA would work with 
each area to establish a submittal schedule. This only applies to one 
area, Sussex Co., DE., based on 1996-98 data.
    Comment: Most commenters did not raise separate issues with respect 
to this specific group of areas. A few commenters specifically noted 
that they supported reinstating the nonattainment designation for these 
areas. Some commenters requested EPA to be clear about what the 
implications are for reinstatement. In particular, they were concerned 
about what planning and control requirements might apply and what would 
be the timing.
    Response: The planning and control requirements that will apply for 
this area are the applicable planning and control requirements in 
subpart 2 of the CAA. The EPA will work with Delaware to determine 
appropriate SIP submittal

[[Page 45193]]

deadlines for any programs that have not yet been submitted.

H. Effective Date and Applicability Dates of Reinstatement

    The EPA proposed to delay the effective date \25\ of any final 
reinstatement notice by 90 days in order to provide areas with a short 
period of time in which to prepare for the applicability of conformity 
and new source requirements which will be triggered by the 
reinstatement of the 1-hour standard and the designations for that 
standard. In the final rule, EPA has retained the 90-day effective 
date. However, for areas that were designated as nonattainment at the 
time EPA revoked the 1-hour standard and that have continued to have 
clean air quality since revocation, EPA is establishing an 
applicability date for the reinstatement of up to 180 days after 
publication of the final rule. These areas are listed in Table 1. 
During this period, EPA will review any pending redesignation requests 
or requests that may be submitted shortly after this final action is 
published. If EPA is able to complete final rulemaking action to 
redesignate an area to attainment during that 180-day period, EPA will 
provide in the final redesignation rule that the area will be 
designated attainment as of the applicability date of this rule, so 
that by the time reinstatement is applicable for any such area, the 
area will receive an attainment designation. In addition, if States are 
able to submit redesignation requests and EPA is able to process such 
requests to the point of final action prior to 180 days from 
publication, the final action approving the redesignation may provide 
that the applicability date of the reinstatement will be the same date 
as the effective date of the redesignation approval, so that the 
redesignations will occur simultaneously with the reinstatement. As 
mentioned before, the 45 areas listed in Table 1 may elect to submit 
redesignation requests.
---------------------------------------------------------------------------

    \25\ See footnote 9, above.
---------------------------------------------------------------------------

    Comment: Some commenters disagreed with the proposed 90-day delay 
in effectiveness, claiming it would be too short a time frame to 
complete conformity determinations on transportation improvement plans 
(TIPs) or for redesignation to occur. One commenter suggested a 180-day 
delay in the effective date. Other commenters believed that the final 
action reinstating the standard and the associated designation should 
be effective immediately. Finally, some commenters supported EPA's 
proposal to make the reinstatement and the associated designations 
effective 90 days after publication.
    Response: With respect to the effective date of the rule, EPA has 
determined, based upon the comments submitted, that a 90-day delayed 
effective date is an appropriate time period for most areas. The time 
from the October 25th proposal to the end of the 90-day period is 
approximately 10 months. The EPA believes this period is sufficient for 
States to complete air quality analyses for conformity determinations 
on transportation plans prior to the effective date of the final rule. 
Thus, areas should not experience any delays in transportation 
projects. At the same time, reinstatement of the standard with the 
associated public health and welfare protections will not be 
significantly delayed. The EPA does not anticipate that areas will 
attempt to complete transportation activities inconsistent with 
reinstatement of the 1-hour standard prior to the effective date, but 
rather that they will use the delay to ensure they are ready to meet 
the applicable requirements when the reinstatement becomes effective. 
Thus, EPA concludes that a 90-day delayed effective date is a 
reasonable accommodation between the competing interests of public 
health protection and transportation planning for most areas.
    The EPA agrees with commenters to the extent it concludes that up 
to a 180-day delay in the applicability of this rule is appropriate for 
areas that were designated nonattainment prior to revocation but that 
currently have clean air quality data sufficient to support a 
redesignation to attainment. Since these areas have continued to have 
clean air since revocation, EPA believes it is appropriate to provide 
up to an additional 90-day delay in the applicability of the rule to 
allow these areas time to quickly complete and submit redesignation 
requests and for EPA to act on submitted requests. Where EPA approves 
such requests on or before the applicability date of this rule, the 
area would be designated attainment at the time the reinstatement of 
the 1-hour standard becomes applicable. The EPA notes again that if EPA 
is taking final action to approve a redesignation prior to 180 days 
from publication of this rule, the final action approving the 
redesignation may provide that the applicability date of the 
reinstatement will be the same date as the effective date of the 
redesignation approval, so that the redesignations will occur 
simultaneously with the reinstatement. Where EPA does not approve a 
redesignation request or one is not submitted, the area will receive 
the nonattainment designation which applied to the area prior to 
revocation upon the applicability date of this rule.
    The EPA notes that all of these areas will again be subject to 
conformity upon the applicability date of the reinstatement of the 1-
hour standard and associated designations, since conformity applies to 
both nonattainment and maintenance areas. As indicated above, EPA 
anticipates that areas will use the delay to complete modeling efforts 
and the consultation process so that they can have a conforming plan 
and TIP in place by the applicability date.

I. Sanction and FIP Clocks

    The EPA's proposed rule provided that any sanctions and FIP clocks 
that were running at the time of the revocation should restart at the 
point that they left off. In other words, if there were 6 months 
remaining in the 2-year period for promulgation of a FIP, those 
remaining 6 months would start to run for that area on the 
applicability date of this action. The EPA is retaining this approach 
in the final rule.
    Comment: Some commenters stated that areas should not be subject to 
any penalties or sanctions. Another commenter requested that EPA impose 
sanctions immediately not only for those areas for which a clock was 
running but also for those areas which may not have submitted a 
required SIP but for which EPA never made a finding that started 
sanctions and FIP clocks. This commenter suggested that sanctions 
should be imposed no later than 90 days after the effective date of the 
reinstatement for all such areas. In contrast, a number of commenters 
supported EPA's approach. These commenters generally contended that 
treating the clocks as if they continued to run during the time when 
the standard did not apply would be considered enforcing the standard 
when it was not in effect. One commenter seemed to support starting the 
clock where it left off at the time of the revocation, but noted that 
sanction clocks with time remaining should not allow States to delay 
progress. The commenter states that areas violating the 1-hour standard 
or contributing to violations in other areas must move forward ``as 
expeditiously as practicable.''
    Response: The EPA believes that the most equitable approach is to 
restart clocks for sanctions or FIPs where they left off at the time of 
the revocation. Because States and sources relied on EPA's final rule 
determining that the standard no longer applied, States were not 
affirmatively moving forward with

[[Page 45194]]

1-hour SIPs. \26\ Thus, EPA believes that it would be unfair to States 
and affected sources to treat those clocks as if they continued to run 
during the time that the 1-hour standard no longer applied.
---------------------------------------------------------------------------

    \26\ One commenter suggests that EPA's actions revoking the 1-
hour standard and related designations were not legally valid at the 
time they were taken. Thus, this commenter claims, that rule cannot 
support a further delay in sanctions or FIPs. The EPA disagrees. The 
EPA revoked the standard in full compliance with its regulation, 40 
CFR 50.9(b), which was not challenged at the time it was 
promulgated.
---------------------------------------------------------------------------

    Similarly, EPA does not believe that it has authority, nor would it 
be appropriate, to begin these clocks over again upon reinstatement or 
to treat these clocks as no longer in effect. The FIP and sanctions 
obligations under sections 110 and 179 of the CAA were previously 
triggered for a State's failure to make a complete SIP submission or an 
approvable submission as required under the CAA. By today's action, 
areas will once again be subject to the same requirements to make 
submissions. There is no basis for ignoring or discharging the State's 
obligation with respect to these submissions. Moreover, EPA agrees that 
sanctions clocks should not be treated by States as a ``grace period'' 
that allows deferral of compliance dates. Where a sanctions clock is in 
place, States should submit plans to stop the clock as expeditiously as 
practicable and should not delay submission until the last minute 
before sanctions are put into place.
    Because EPA is taking action to put areas back in the place they 
were in prior to the revocation, the most appropriate course of action 
is to restart these clocks where they left off. Therefore, upon the 
applicability date of today's action, any sanctions or FIP clocks that 
were running based on a State's default for a required submission will 
restart at the point it was on the effective date of the revocation. 
States should work to submit SIPs as expeditiously as practicable. Any 
questions regarding the status of a sanction or FIP clock for a 
specific area should be directed to the appropriate EPA Regional 
Office. Finally EPA has no authority to impose sanctions where EPA has 
not made appropriate findings to trigger clocks under section 179.

J. Conformity

    The EPA proposed that conformity would apply upon the effective 
date of the rule to all areas again designated nonattainment. The EPA 
noted that these areas would need to have a conforming transportation 
plan and program in place by the effective date of the rule in order to 
fund new transportation projects after that date. The EPA also noted 
that conformity has continued to apply to all attainment areas with 
maintenance plans even after revocation, and that conformity does not 
apply at all to attainment areas without maintenance plans. Upon the 
applicability date \27\ of this final action, conformity will apply to 
all designated nonattainment and maintenance areas as proposed.
---------------------------------------------------------------------------

    \27\ See footnote 9 and section H. above for explanation of 
terms ``effective date'' and ``applicability date.''
---------------------------------------------------------------------------

    Several commenters expressed concerns about the conformity 
requirements that apply to nonattainment and maintenance areas and the 
timing of conformity determinations. The specific comments and 
responses follow.
    Comment: The transportation conformity rule requires conformity to 
be determined at least every 3 years. Commenters requested that we not 
consider the 3-year clock to have been running in nonattainment areas 
where the 1-hour ozone standard was revoked and conformity did not 
apply.
    Response: We agree that in ozone nonattainment areas where the 
ozone standard was revoked and conformity stopped applying, any of the 
3-year or 18-month clocks (described in 40 CFR 93.104 \28\) that were 
running at the time of the revocation were stayed on the effective date 
of the revocation. On the applicability date of this final rule, those 
clocks will pick up again at the point where they left off.
---------------------------------------------------------------------------

    \28\ The EPA's conformity regulations require States to 
redetermine conformity for all transportation plans and programs 
every 3 years. 40 CFR 93.104(b)(3) and (c)(3). The regulations also 
require a conformity determination within 18 months of various SIP 
submittal and approval actions. 40 CFR 93.104(e).
---------------------------------------------------------------------------

    In practice, this means that if an ozone nonattainment area had a 
conforming TIP at the time of the revocation and did not amend the plan 
and TIP with respect to any non-exempt projects during the time 
conformity did not apply, the transportation plan and TIP would 
continue to be considered ``currently conforming'' even if more than 3 
years have elapsed since the conformity determination.
    The area would need to document that the transportation plan and 
TIP have not changed since the time of the last conformity 
determination in a manner that would have required a new conformity 
determination. The area should also clearly identify how much time 
remains on the 3-year clock and any 18-month clock that was triggered 
by 40 CFR 93.104.
    We are not concerned that the temporary halt of the clocks in 40 
CFR 93.104 will result in transportation plans and TIPs that are 
relying on very old conformity determinations. The Department of 
Transportation (DOT) requires transportation plans and TIPs to be 
regularly updated, and those planning clocks have been running 
regardless of the revocation. The plan and TIP updates require 
conformity determinations. Therefore, any plans and TIPs with 
conformity determinations from before the revocation will be updated 
soon under DOT's planning regulations.
    For any plans and TIPs that were amended with respect to non-exempt 
projects while the ozone standard was revoked, a new conformity 
determination will be required by the time the reinstatement is 
applicable. This is because these plans and TIPs will generally not yet 
have been found to conform and would have to be found to conform by the 
applicability date of reinstatement to enable projects to proceed.
    Comment: One commenter asked what process is required for areas 
that voluntarily complied with conformity requirements while the ozone 
standard was revoked.
    Response: If an area amended its plan and TIP while the ozone 
standard was revoked, but the amendment(s) fully met the requirements 
of the conformity rule (including public participation), the area would 
simply need to document this and receive confirmation from the Federal 
agencies that the transportation plan and TIP are considered 
``currently conforming.''
    Comment: Some commenters were concerned that they do not have 
enough time to determine conformity before the reinstatement is 
applicable, and/or that it is burdensome to determine conformity of the 
current plan and TIP when they are updating the plan and TIP very soon 
(which will also require a conformity determination).
    Response: We understand that this final rule changes the usual 
cycle for determining conformity. Counting from the time we proposed to 
reinstate the standard, areas will have had at least ten months to 
complete the conformity process prior to the applicability date of this 
rule. We believe this is a reasonable time frame, although we recognize 
that the timing for this conformity process may not be optimal for some 
areas.
    We must balance the desire for additional time for transportation 
planning with the need to protect public health with the 1-hour ozone 
standard and statutory requirement for conformity determinations. In 
some areas, transportation investments were planned or approved during 
the

[[Page 45195]]

revocation without a demonstration that they will not interfere with 
attainment of the one-hour ozone standard. It is important to conduct 
such a demonstration expeditiously so that areas do not irreversibly 
commit to transportation projects that are inconsistent with healthy 
air.
    Comment: One commenter stated that the proposed criteria for 
conformity are not consistent with the March 2, 1999 decision of the 
Court of Appeals in EDF v. EPA, 167 F.3d 641,650 (1999) on conformity. 
The commenter argues that the court required EPA to develop a test to 
ensure conformity consistent with CAA 176(c)(1) and that this must be 
done now for all areas where the standard is to be reinstated.
    Response: Conformity determinations should comply with the CAA, as 
recently interpreted in the EPA and DOT guidance issued in response to 
the March 1999 court decision (EPA's May 14, 1999 guidance entitled, 
``Conformity Guidance on Implementation of March 2, 1999 Conformity 
Court Decision'' and DOT's June 18, 1999 guidance entitled, 
``Additional Supplemental Guidance for the Implementation of the 
Circuit Court Decision Affecting Transportation Conformity''). We 
believe that these guidance documents are consistent with the court's 
decision and that conformity determinations performed consistent with 
the guidance are legally sound. We will be formally proposing to amend 
the transportation conformity rule to incorporate this guidance, 
pursuant to CAA section 176(c)(4)(A).
    The commenter appears to believe that the court decision required 
EPA to develop additional criteria to satisfy the obligations of 
section 176(c)(1) of the CAA, which require Federal agencies and 
Metropolitan Planning Organizations (MPOs) to determine that Federal 
actions will not interfere with timely attainment, in situations where 
they are determining conformity to budgets in submitted SIPs. However, 
EPA believes that the court in actuality merely remanded EPA's rules, 
stating that ``where EPA fails to determine the adequacy of motor 
vehicle emissions budgets in a SIP revision within 45 days of 
submission, * * * there is no reason to believe that transportation 
plans and programs conforming to the submitted budgets will [meet the 
statutory tests in section 176(c)(1)(B)].'' The EPA interprets this 
aspect of the decision to require it to revise its regulations to 
mandate that EPA make affirmative findings of adequacy on all submitted 
SIPs before they can be used for conformity purposes. The procedure for 
doing this is outlined in the guidance mentioned above. The EPA does 
not believe the court addressed any deficiency in EPA's regulations 
governing conformity determinations in situations where EPA has made a 
positive finding of adequacy. The EPA concludes that the court only 
remanded the aspect of EPA's regulations at 40 CFR 93.118(e)(1) which 
allows use of submitted SIPs which EPA has not yet found adequate, 
since it did not remand either EPA's regulations at 40 CFR 93.118(e)(4) 
establishing criteria for finding budgets adequate or 93.118(e)(6) 
requiring additional findings by Federal agencies and MPOs where 
conformity determinations are made to submitted SIPs. Therefore, EPA 
believes that conformity determinations consistent with these two 
provisions and our guidance on finding budgets adequate fully satisfy 
the requirements of the CAA and we intend to revise our regulations 
consistent with that guidance. Of course, commenters will have the 
opportunity to comment on those regulatory changes when they are 
proposed and to raise any issues associated with EPA's interpretation 
of the court opinion at that time. The EPA does not believe that such 
comments are directly relevant to this rulemaking and, therefore, is 
not making any changes to the conformity rules in connection with this 
final action.
    Comment: One commenter argued that conformity to adequate SIP 
budgets in nonattainment areas, should continue even after any future 
revocations until new adequate budgets are submitted for the 8-hour 
standard.
    Response: Section 176(c)(5) of the CAA clearly provides that 
conformity requirements only apply in nonattainment areas and areas 
that had been nonattainment and were subsequently redesignated to 
attainment and are subject to the requirement to develop a maintenance 
plan. Since nonattainment areas where EPA may in the future revoke the 
1-hour standard once an 8-hour standard becomes fully enforceable will 
no longer be designated nonattainment or subject to the requirement to 
submit a maintenance plan, for the reasons explained above, EPA 
concludes that it would have no authority under section 176(c) to 
require conformity to previously submitted 1-hour budgets after any 
future revocations.

K. New Source Review

    In the October 25th proposal, EPA solicited comment on what NSR 
requirements should apply in areas that had, subsequent to our findings 
that the 1-hour standard no longer applied, revoked their nonattainment 
NSR programs. Specifically, EPA asked whether 40 CFR part 51, Appendix 
S should be followed or the higher offset/major source thresholds in 
subpart 2 of the CAA should be followed in nonattainment areas where 
the SIP lacks the applicable nonattainment NSR provisions.
    Comment: Several commenters wanted flexibility in applying NSR 
requirements. There was a mixed reaction for and against using 40 CFR 
appendix S. As to the question of whether States must issue permits 
consistent with the additional requirements of subpart 2, even in the 
absence of an approved NSR SIP, one commenter stated that it was not 
supportive of any EPA action that would cause enforcement of NSR on 
facilities that were or are under no legal obligation to comply with 
NSR requirements. Another commenter urged EPA to require sources to 
comply with subpart 2 notwithstanding the lack of an approved SIP, 
citing a 1992 EPA policy memorandum as support.
    Response: The EPA solicited comment on how to address areas that 
were designated nonattainment prior to the findings that the 1-hour 
standard no longer applied and which, since revocation, had amended 
their SIPs to remove the applicable nonattainment NSR provisions. The 
EPA has determined that it is unnecessary to resolve this question in 
this rulemaking, as we have determined that no area has amended its SIP 
since the nonattainment designations were removed. Thus, the applicable 
SIPs in each area will specify the nonattainment NSR responsibilities 
of sources in the area, without any action by EPA.
    Comment: Sources that have applied for PSD permits during the 
period that the 1-hour ozone standard did not apply should not have to 
seek part D NSR permits. Allowing sources with complete applications to 
avoid more stringent requirements is consistent with EPA policy. Such 
an approach is also consistent with how EPA acted following the 
adoption of PM10 as the indicator for particulate matter in 
1987. At that time, EPA allowed sources with complete PSD permit 
applications that did not account for the sources' PM10 
emissions to be grandfathered.
    Response: Whether or not sources must apply for part D 
nonattainment NSR permits upon reinstatement of the 1-hour standard 
will be determined by the applicable SIP. The EPA expects that most, if 
not all, SIPs already specify that sources in designated nonattainment 
areas must obtain part D permits. Accordingly, some sources may have to 
revise their permit applications. Even if EPA were to agree that it 
would

[[Page 45196]]

be appropriate to allow such sources to obtain PSD permits rather than 
nonattainment NSR permits, EPA cannot override by policy the legal 
requirements of a more stringent applicable SIP. Regarding the 
PM10 transition policy to which the commenter refers, that 
policy is inapplicable in the present situation because it did not deal 
with the kind of situation at issue currently--where areas will be 
switching from one designation status (no designation) to 
nonattainment. The EPA had concluded in that rulemaking that part D, 
including part D NSR, did not apply at all to the revised particulate 
matter NAAQS, so there was not a question about which NSR program would 
apply. See 52 FR 24672, 24678 (July 1, 1987).

L. Miscellaneous Comments

    Comment: One commenter noted that EPA should notify the public of 
the terms of a stipulation agreement reached between EPA and the 
Environmental Defense Fund (EDF) wherein EPA agreed to accept comment 
on certain items in the reinstatement notice.
    Response: In its notice reopening the comment period on Dec. 8, 
1999, EPA explicitly provided that it would accept comment on the list 
of issues recited in the stipulation filed in EDF v. EPA, (D.C. Cir., 
No. 98-1363). (64 FR 68659, December 8, 1999).
    Comment: Several commenters supported applying the reinstatement 
retroactively, such that areas would be treated as if the standard and 
the associated designations have always applied. Some were not 
supportive of retroactively applying the 1-hour standard during the 
time it was revoked. With respect to conformity determinations, one 
commenter believed that we shouldn't allow ``grandfathering'' of 
projects if prior conformity determinations would have lapsed during 
the time the standard was not applicable; they believe that in cases 
where it is not possible to reverse actions, then they must be subject 
to some mitigation procedure to address actions that allowed for 
emission increases during that time.
    Response: The EPA concludes that it is not appropriate to apply the 
reinstatement of the 1-hour standard retroactively. The EPA believes 
that it had full authority to revoke the 1-hour standard initially, and 
that its actions were legal and proper at the time they were taken. 
Although EPA now concludes that it should rescind those actions due to 
changed circumstances, it would be unfair to areas that had relied on 
the initial revocations (and to sources located in those areas) to 
apply the rescissions retroactively. Many areas took actions during the 
period of time that the 1-hour standard was not applicable that 
properly relied on the inapplicability of that standard. Rules altering 
prior actions are generally applied only prospectively and are applied 
retroactively only in unusual cases, for instance where an agency did 
not have the authority to take a prior action initially. Courts 
generally view retroactive application of administrative rules with 
disfavor unless such application is specifically sanctioned by statute. 
Bowen v. Georgetown University Hospital, 488 U.S. 204 (1988). The CAA 
does not specifically provide for retroactive application of 
regulations under title I. Therefore, although EPA might have authority 
to apply the reinstatement retroactively if a court determined that 
EPA's action in revoking the standard was illegal, EPA does not believe 
it is appropriate to do so here where EPA believes it was fully 
authorized to revoke the standard at the time it took such action.
    The EPA also concludes for similar reasons that it would not be 
appropriate for conformity purposes to treat conformity determinations 
as having lapsed during the time that the 1-hour standard was not 
applicable to an area. Because the 1-hour standard no longer applied 
during that period, areas were not on notice that conformity 
determinations were to lapse. It would be equally unfair to areas to 
achieve a similar result by denying grandfathering status under the 
conformity rules to any project approved during a time period when 
conformity status would have lapsed if the standard had been 
applicable. The EPA concludes that areas should be allowed to continue 
to rely on the inapplicability of the 1-hour standard during the period 
between revocation and reinstatement because EPA had the authority to 
revoke the standard and properly revoked it initially.\29\
---------------------------------------------------------------------------

    \29\ One commenter notes that some areas should have been on 
notice that revocations were questionable since one action 
promulgating revocations was not published in the Federal Register 
until after May 14, 1999, the date of the adverse court decision in 
ATA (64 FR 30911, June 9, 1999). However, that final action of the 
Administrator was taken (final rulemaking notice signed by the 
Administrator) on May 12, 1999, prior to the court decision; only 
publication occurred after the decision. The EPA did not take any 
further actions revoking the 1-hour standard in any areas after the 
date of the ATA decision.
---------------------------------------------------------------------------

    For these same reasons, EPA concludes that where highway projects 
or new sources have already been constructed, areas should not be 
required to immediately implement mitigation measures to remedy any 
resulting emissions increases. Areas will effectively have to provide 
for mitigation in future transportation and air quality planning once 
the 1-hour standard is reinstated. All future air quality planning for 
attainment and reasonable further progress as well as conformity 
determinations will have to account for emissions from such activities. 
However, EPA believes that it would be inequitable to require areas to 
immediately institute specific mitigation measures to account for any 
emissions increases that may have occurred during the time that the 
standard was not applicable to an area.
    Comment: Several commenters took the opportunity to comment on the 
8-hour ozone standard. Many requested that designations for the 8-hour 
standard not be made until legal issues are resolved. Many asked for 
guidance to States on meeting the 8-hour standard in the interim. 
Several called upon the Agency to revoke the 8-hour standard.
    Response: The numerous comments concerning the 8-hour standard, 
including those relating to designations under the 8-hour standard, 
guidance on implementation of the 8-hour standard, and requests for 
revocation of the 8-hour standard, are not relevant to this rulemaking 
on reinstatement of the 1-hour standard. The EPA will address issues 
relating to the 8-hour standard in separate rulemaking actions or 
guidance documents.
    Comment: One commenter suggested that we explore the Flexible 
Attainment Region (FAR) approach to provide flexibility to States in 
determining measures to prevent air quality deterioration and to 
improve air quality. The commenter suggests that EPA give these 
``voluntary programs'' time to work before triggering nonattainment 
designations. The same commenter also requests EPA to extend to ozone 
areas the flexibility provided in EPA's draft guidance for PM-10 
nonattaiment areas with respect to limited maintenance plans.
    Response: The EPA has used the FAR approach in the past with 
respect to areas designated attainment but that are violating the ozone 
standard. As provided above, EPA has some discretion in deciding 
whether to redesignate such areas as nonattainment. In exercising that 
discretion, EPA may consider ``planning and control'' activities. Thus, 
in the past, EPA has not moved forward to redesignate to nonattainment 
attainment areas that were voluntarily adopting and implementing 
measures to address violations. The EPA plans to continue this approach 
for such areas as explained in sections III.D and E, above.

[[Page 45197]]

However, as also explained above, EPA does not believe it has the 
authority to reinstate the standard and not designate as nonattainment 
those areas designated as nonattainment at the time of the revocation 
action. These areas would be subject to the specific planning 
requirements that Congress provided under the CAA until they qualify 
for redesignation. The EPA cannot ignore the statutory mandate in favor 
of more flexible means of achieving attainment that could be allowed 
under the FAR approach. Therefore, designated nonattainment areas 
cannot use a FAR because the statutory requirements apply.
    With respect to the comment regarding EPA's draft limited 
maintenance plan guidance for PM-10 areas seeking redesignation from 
nonattainment to attainment, EPA notes that it has an existing limited 
maintenance plan policy for ozone (``Limited Maintenance Plan Option 
for Nonclassifiable Ozone Nonattainment Areas,'' November 16, 1994, 
Sally Shaver) This policy provides some flexibility, e.g., no 
requirement to project emissions out into the future, no need for 
maintenance demonstration since met by meeting the NAAQS, etc. The 
commenter appears not to recognize that such a policy exists and does 
not further explain what flexibilities in the draft PM-10 policy they 
would like extended to ozone areas.

IV. What Administrative Requirements Are Considered in Today's 
Final Rule?

A. Executive Order 12866: Regulatory Impact Analysis

    Under Executive Order 12866, [58 FR 51,735 (October 4, 1993)] the 
Agency must determine whether the regulatory action is ``significant'' 
and therefore subject to Office of Management and Budget (OMB) review 
and the requirements of the Executive Order. The Order defines 
``significant regulatory action'' as one that is likely to result in a 
rule that may:
    (1) Have an annual effect on the economy of $100 million or more or 
adversely affect in a material way the economy, a sector of the 
economy, productivity, competition, jobs, the environment, public 
health or safety, or State, local, or tribal governments or 
communities;
    (2) Create a serious inconsistency or otherwise interfere with an 
action taken or planned by another agency;
    (3) Materially alter the budgetary impact of entitlements, grants, 
user fees, or loan programs or the rights and obligations of recipients 
thereof; or
    (4) Raise novel legal or policy issues arising out of legal 
mandates, the President's priorities, or the principles set forth in 
the Executive Order.
    It has been determined that this final rule is a ``significant 
regulatory action'' under the terms of Executive Order 12866; 
therefore, it was submitted to OMB for their review.

B. Regulatory Flexibility Act 

    Under the Regulatory Flexibility Act (RFA), 5 U.S.C. 601 et seq., 
EPA must prepare a regulatory flexibility analysis assessing the impact 
of any proposed or final rule on small entities (5 U.S.C. 603 and 604), 
unless EPA certifies that the rule will not have a significant impact 
on a substantial number of small entities. Small entities include small 
businesses, small not-for-profit enterprises, and government entities 
with jurisdiction over populations of less than 50,000. The EPA is 
certifying that this final rule will not have a significant impact on a 
substantial number of small entities because the determination that the 
1-hour standard again applies does not itself directly impose any new 
requirements on small entities. See Mid-Tex Electric Cooperative, Inc. 
v. FERC, 773 F.2d 327 (D.C. Cir. 1985) (agency's certification need 
only consider the rule's impact on entities subject to the requirements 
of the rule). Instead, this rule merely establishes that the 1-hour 
standard again applies in certain areas. For the most part, any 
requirements applicable to small entities that may indirectly apply as 
a result of this action would be imposed independently by the State 
under its SIP, not by EPA through this action. Moreover, to the extent 
this rule would automatically trigger the applicability of certain SIP 
requirements to small entities (e.g., NSR), this rule cannot itself be 
tailored to address small entities that would be subject to those 
requirements.
    One requirement that may apply immediately upon this action to all 
designated nonattainment areas is the requirement under CAA section 
176(c) and associated regulations to demonstrate conformity of Federal 
actions to SIPs. However, those rules only apply directly to Federal 
agencies and MPOs, which by definition are designated only for 
metropolitan areas with a population of at least 50,000 and thus do not 
meet the definition of small entities under the RFA. Therefore, I 
certify that this action will not have a significant impact on a 
substantial number of small entities within the meaning of those terms 
for RFA purposes.

C. Unfunded Mandates

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 
Law 104-4, establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and tribal 
governments, and the private sector. Under section 202 of UMRA, EPA 
generally must prepare a written statement, including a cost-benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures by State, local, and tribal governments, in 
the aggregate, or by the private sector, of $100 million or more in any 
one year. Before promulgating an EPA rule for which a written statement 
is needed, section 205 of UMRA generally requires EPA to identify and 
consider a reasonable number of regulatory alternatives and adopt the 
least costly, most cost-effective or least burdensome alternative that 
achieves the objectives of the rule. The provisions of section 205 do 
not apply when they are inconsistent with applicable law. Moreover, 
section 205 allows EPA to adopt an alternative other than the least 
costly, most cost-effective or least burdensome alternative if the 
Administrator publishes with the final rule an explanation why that 
alternative was not adopted. Before EPA establishes any regulatory 
requirements that may significantly or uniquely affect small 
governments, including tribal governments, it mush have developed under 
section 203 of UMRA a small government agency plan. The plan must 
provide for notifying potentially affected small governments, enabling 
officials of affected small governments to have meaningful and timely 
input in the development of EPA regulatory proposals with significant 
Federal intergovernmental mandates, and informing, educating, and 
advising small governments on compliance with the regulatory 
requirements.
    Today's final action does not include a Federal mandate within the 
meaning of UMRA that may result in expenditures of $100 million or more 
in any one year by either State, local, or tribal governments in the 
aggregate or to the private sector. This rule would reinstate the 
applicability of the 1-hour ozone standard and alter the designation 
status of areas. The consequences of this action may result in some 
additional costs within the affected areas, but these costs would not 
exceed $100 million per year in the aggregate.\30\ In view of recent 
concerns about increased gas prices in

[[Page 45198]]

certain areas, we specifically note that this action will not impose 
any requirements on gasoline and will not affect current gas prices.
---------------------------------------------------------------------------

    \30\ See Docket A-99-22, III-B-04, ``Preliminary Assessment of 
the Incremental Burden Associated with Reinstatement of the 1-Hour 
Ozone Standard for UMRA, dated October 14, 1999.

    One mandate that may apply as a consequence of this action to all 
designated nonattainment areas is the requirement under CAA section 
176(c) and associated regulations to demonstrate conformity of Federal 
actions to SIPs. These rules apply to Federal agencies and MPOs making 
conformity determinations. The EPA concludes that such conformity 
determinations will not cost $100 million or more in the aggregate 
annually.\31\

    \31\ See footnote 30, above.
---------------------------------------------------------------------------

    In addition, some areas with recent air quality violations will 
have to take the additional steps specified in their maintenance plans 
to limit emissions of air pollutants. These measures could, for 
example, include revising the threshold for NSR, establishing 
reasonable available control technology (RACT) level control for 
additional sources, and establishing or enhancing inspection and 
maintenance (I/M) programs within the area. These measures vary 
substantially in terms of the expected emissions reductions and their 
potential cost. Because the affected jurisdictions have some 
flexibility to choose among these measures, it is difficult to estimate 
the overall cost of these additional controls. The EPA believes that 
the affected areas are already carrying out many of the other 
obligations associated with this action. For example, most areas that 
would have a nonattainment designation reinstated upon reinstatement of 
the 1-hour standard already have NSR requirements under their existing 
SIP programs. In addition, many of these areas are located in the 
Northeast Ozone Transport Region and are already carrying out many of 
the requirements associated with the reinstatement of the 1-hour 
standard. Therefore, EPA believes that any new controls imposed as a 
result of this action will not cost in the aggregate $100 million or 
more annually. Thus, this Federal action will not impose mandates that 
will require expenditures of $100 million or more in the aggregate in 
any one year.

D. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    Executive Order 13045: ``Protection of Children from Environmental 
Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997) applies 
to any rule that: (1) is determined to be ``economically significant'' 
as defined under Executive Order 12866, and (2) concerns an 
environmental health or safety risk that EPA has reason to believe may 
have a disproportionate effect on children. If the regulatory action 
meets both criteria, the Agency must evaluate the environmental health 
or safety effects of the planned rule on children, and explain why the 
planned regulation is preferable to other potentially effective and 
reasonably feasible alternatives considered by the Agency.
    The EPA interprets Executive Order 13045 as applying only to those 
major regulatory actions that are based on health or safety risks, such 
that the analysis required under section 5-501 of the Order has the 
potential to influence the regulation. This final rule is not subject 
to Executive Order 13045 because it does not meet either of the above 
criteria. It is not economically significant as defined under Executive 
Order 12866, and it implements a previously promulgated health or 
safety-based Federal standard and does not itself involve decisions 
that affect environmental health or safety risks.

E. Submission to Congress and the General Accounting Office

    Under 5 U.S.C. 801(a)(1)(A), as added by the Small Business 
Regulatory Enforcement Fairness Act of 1996, EPA submitted a report 
containing this rule and other required information to the U.S. Senate, 
the U.S. House of Representatives and the Comptroller General of the 
General Accounting Office prior to publication of the rule in today's 
Federal Register. This rule is not a ``major rule'' as defined by 5 
U.S.C. 804(2).

F. Executive Order 13132: Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that have ``substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.''
    Under Section 6 of Executive Order 13132, EPA may not issue a 
regulation that has federalism implications, that imposes substantial 
direct compliance costs, and that is not required by statute, unless 
the Federal government provides the funds necessary to pay the direct 
compliance costs incurred by State and local governments, or EPA 
consults with State and local officials early in the process of 
developing the proposed regulation. The EPA also may not issue a 
regulation that has federalism implications and that preempts State 
law, unless the Agency consults with State and local officials early in 
the process of developing the proposed regulation.
    As indicated in the proposal, EPA does not believe that this final 
rule has federalism implications within the meaning of the Executive 
Order. EPA has reached this conclusion for several reasons. As 
discussed above in connection with UMRA, this action will not impose 
substantial direct compliance costs on the States nor will it alter the 
relationship between the national government and the States, or the 
distribution of power and responsibilities among the various levels of 
government. As noted previously, this rule simply reinstates the 
applicability of the 1-hour ozone standard and the associated air 
quality designations for various areas that had applied prior to 
revocation. These actions do not preempt any State authority or 
otherwise affect State flexibility to comply with the Clean Air Act. 
Although reinstatement will alter the number of areas within various 
states that are designated under the 1-hour standard, it will not alter 
the relationships that currently exist between the States and the 
federal government with respect to areas designated under the 1-hour 
standard. Thus, EPA concludes that the requirements of section 6 of the 
Executive Order do not apply to this rule.
    In the spirit of the Executive Order however, the Agency has 
consulted extensively with representatives of State and local 
governments, including elected officials. As EPA was developing the 
proposal and again when EPA issued the proposal, we phoned elected 
officials or their staff for many of the areas that could be affected 
by the rule to notify them that EPA was considering reinstating the 1-
hour ozone standard and to solicit their advice and concerns. The EPA 
also notified national organizations of state and local government 
officials and made EPA staff available to discuss the proposed action 
with the organization staff and their members. These organizations 
included the U.S. Conference of Mayors (USCM), the National Conference 
of Black Mayors, the National Governors Association, the National 
Council of State Legislators, the National Association of Counties, 
ECOS, STAPPA/ALAPCO, the National

[[Page 45199]]

Association of Local Government Environmental Professionals, and the 
Ozone Transport Commission. For example, EPA's Assistant Administrator 
for Air and Radiation held a conference call with the USCM Energy and 
Environment Committee members when the proposal was announced. In 
addition, EPA sent letters to the Governors and their environmental 
commissioners to ensure that they were aware of the proposal and could 
comment on it. It was in response to concerns raised by these contacts 
that EPA proposed to delay the effective date of the reinstatement for 
90 days so that areas would have adequate time to comply with any 
requirements triggered by reinstatement. In addition, based on comments 
received from States after publication of the proposal, EPA decided to 
provide a 180-day delayed applicability date for areas that were 
designated nonattainment but currently have clean air data. EPA also 
notes that, while it received no adverse comments regarding the 
statements in the proposal concerning the lack of federalism 
implications of this rule, it received numerous comments on the rule 
from state and local governments. EPA has responded fully to all 
comments raised by the various State and local governments, as 
explained above in the sections of this notice describing the comments 
and EPA's response to them.

G. Executive Order 13084: Consultation and Coordination With Indian 
Tribal Governments

    Under Executive Order 13084, EPA may not issue a regulation that is 
not required by statute that significantly or uniquely affects the 
communities of Indian tribal governments, and that imposes substantial 
direct compliance costs on those communities, unless the Federal 
government provides the funds necessary to pay the direct compliance 
costs incurred by the tribal governments, or EPA consults with those 
governments. If EPA complies by consulting, Executive Order 13084 
requires EPA to provide to OMB, in a separately identified section of 
the preamble to the rule, a description of the extent of EPA's prior 
consultation with representatives of affected tribal governments, a 
summary of the nature of their concerns, and a statement supporting the 
need to issue the regulation. In addition, Executive Order 13084 
requires EPA to develop an effective process permitting elected 
officials and other representatives of Indian tribal governments ``to 
provide meaningful and timely input in the development of regulatory 
policies on matters that significantly or uniquely affect their 
communities.''
    Today's final rule does not significantly or uniquely affect the 
communities of Indian tribal governments. This final action does not 
involve or impose any requirements that directly affect Indian tribes. 
Under EPA's tribal authority rule, tribes are not required to implement 
CAA programs but, instead, have the opportunity to do so. Accordingly, 
the requirements of section 3(b) of Executive Order 13084 do not apply 
to this rule.

H. Paperwork Reduction Act

    This final action does not contain any information collection 
requirements which require OMB approval under the Paperwork Reduction 
Act (44 U.S.C. 3501 et seq.).

I. Executive Order 12898: Environmental Justice

    Under Executive Order 12898, each Federal agency must make 
achieving environmental justice part of its mission by identifying and 
addressing, as appropriate, disproportionately high and adverse human 
health or environmental effects of its programs, policies, and 
activities on minorities and low-income populations. Today's final 
action to reinstate the applicability of the 1-hour standard in certain 
areas does not have a disproportionate adverse affect on minorities and 
low-income populations.

J. National Technology Transfer and Advancement Act

    Section 12 of the National Technology Transfer and Advancement Act 
(NTTAA) of 1995 requires Federal agencies to evaluate existing 
technical standards when developing new regulations. To comply with 
NTTAA, the EPA must consider and use ``voluntary consensus standards'' 
(VCS) if available and applicable when developing programs and policies 
unless doing so would be inconsistent with applicable law or otherwise 
impractical.
    The EPA believes that VCS are inapplicable to this final action. 
Today's final action does not require the public to perform activities 
conducive to the use of VCS.

K. Rule Effective Date and Applicability Dates

    The EPA finds that there is good cause for this final action to 
become effective \32\ and applicable either 90 or 180 days after 
publication, depending upon type of area, since this would afford areas 
time to get programs, such as conformity SIPs or redesignation 
requests, in place. The EPA believes these are reasonable periods of 
time to accommodate the competing interests of efficient air quality 
and transportation planning and prompt public health protection. The 
EPA has general administrative authority under section 301(a) of the 
CAA and 5 U.S.C. 553(d) to establish the effective date and 
applicability dates of a rule provided any delay in effective date or 
applicability dates is reasonable. ASG Industries v. Consumer Product 
Safety Commission, 593 F.2d 1323, 1335 (D.C. Cir. 1979). A 90- or 180-
day delay in effective or applicability date for a rule where areas 
will have to develop various SIP emission control programs by the 
effective or applicability date of the rule is reasonable. See Small 
Refiner Lead Phase-Down Task Force v. EPA, 705 F.2d 506 (D.C. Cir. 
1983) (EPA's decision to grant an 8-month period between date of 
promulgation and effective date was reasonable where regulated entities 
needed time to implement controls). The longer time period for areas 
that are not experiencing violations is reasonable because no 
violations are occurring in these areas. Moreover, EPA will need 
additional time to take final action to redesignate areas as attainment 
after States submit their plans to EPA.

L. Petitions for Judicial Review

    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by September 18, 2000. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this rule for the purposes of judicial review nor does 
it extend the time within which a petition for judicial review may be 
filed, and shall not postpone the effectiveness of such rule or action. 
This action may not be challenged later in proceedings to enforce its 
requirements (see section 307(b)(2)).

 Phoenix Area:
    Maricopa County (part)..............     11/15/90  Nonattainment............................      2/13/98  Serious.
         The Urban Planning Area of the
         Maricopa Association of
         Governments is bounded as
         follows:
             1. Commencing at a point
             which is at the
             intersection of the eastern
             line of Range 7 East, Gila
             and Salt River Baseline and
             Meridian, and the southern
             line of Township 2 South,
             said point is the
             southeastern corner of the
             Maricopa Association of
             Governments Urban Planning
             Area, which is the point of
             beginning;
             2. Thence, proceed
             northerly along the eastern
             line of Range 7 East which
             is the common boundary
             between Maricopa and Pinal
             Counties, as described in
             Arizona Revised Statute
             Section 11-109, to a point
             where the eastern line of
             Range 7 East intersects the
             northern line of Township 1
             North, said point is also
             the intersection of the
             Maricopa County Line and
             the Tonto National Forest
             Boundary, as established by
             Executive Order 869 dated
             July 1, 1908, as amended
             and showed on the U.S.
             Forest Service 1969
             Planimetric Maps;
             3. Thence, westerly along
             the northern line of
             Township 1 North to
             approximately the southwest
             corner of the southeast
             quarter of Section 35,
             Township 2 North, Range 7
             East, said point being the
             boundary of the Tonto
             National Forest and Usery
             Mountain Semi-Regional
             Park;
             4. Thence, northerly along
             the Tonto National Forest
             Boundary, which is
             generally the western line
             of the east half of
             Sections 26 and 35 of
             Township 2 North, Range 7
             East, to a point which is
             where the quarter section
             line intersects with the
             northern line of Section
             26, Township 2 North, Range
             7 East, said point also
             being the northeast corner
             of the Usery Mountain Semi-
             Regional Park;
             5. Thence, westerly along
             the Tonto National Forest
             Boundary, which is
             generally the south line of
             Sections 19, 20, 21 and 22
             and the southern line of
             the west half of Section
             23, Township 2 North, Range
             7 East, to a point which is
             the southwest corner of
             Section 19, Township 2
             North, Range 7 East;
             6. Thence, northerly along
             the Tonto National Forest
             Boundary to a point where
             the Tonto National Forest
             Boundary intersects with
             the eastern boundary of the
             Salt River Indian
             Reservation, generally
             described as the center
