SUPPLEMENTARY INFORMATION:
I. Background
On October 6, 1997 Arizona submitted a request to redesignate the
CO Tucson Air Planning Area (TAPA) nonattainment area to attainment for
the NAAQS and for approval of a maintenance plan. EPA found that the
TAPA met all the redesignation requirements specified in section
107(d)(3)(E) of the Clean Air Act (CAA) and also that the TAPA was
eligible to use the Limited Maintenance Plan (LMP) option provided for
in EPA guidance.\1\ EPA therefore proposed approval of the request and
the maintenance plan on July 22, 1998 (see 63 FR 39258) and provided
for a 30-day public comment period.
---------------------------------------------------------------------------
\1\ Memorandum entitled ``Limited Maintenance Plan Option for
Nonclassifiable CO Nonattainment Areas'', from Joseph W. Paisie,
Group Leader, Integrated Policy and Strategies Group, Office of Air
Quality Planning and Standards, U.S. EPA, Research Triangle Park,
North Carolina, October 6, 1995.
---------------------------------------------------------------------------
For a full discussion of EPA's evaluation of the TAPA redesignation
request and the maintenance plan, the reader is referred to the
original EPA proposal (63 FR 39258, July 22, 1998) and to the Technical
Support Document (TSD) accompanying that proposal notice which may be
found in the docket on file at the addresses noted above.
EPA received one set of comments during the 30-day comment period
provided under the original proposal. Those comments came from the
Arizona Center for Law in the Public Interest (ACLPI) in a letter dated
August 21, 1998. To respond to the public comments, EPA requested
supplementary information from the Pima Association of Governments
(PAG) relating to CO emissions projections for the area for the 10-year
maintenance period extending through 2010. EPA received the information
in a letter from PAG dated June 18, 1999. EPA is responding to ACLPI's
comments in section II below. On December 17, 1999 (see 64 FR 70660)
EPA reproposed to approve the TAPA redesignation request in order to
provide the public with the opportunity to comment on the additional
information provided by PAG and on additional issues that had arisen
since the original proposal. EPA received no public comments during the
30-day public comment period provided under the reproposal.
II. Public Comment and EPA Responses
EPA has considered all of the comments received from ACLPI on the
original proposal and is providing the following responses.
Comment: ACLPI expressed concern that one of the CAA's requirements
for redesignation, namely that the improvement in air quality is due to
permanent and enforceable reductions, would not be met by the TAPA
following redesignation because several Arizona statutes, including the
state's auto emission inspection and maintenance program, the
oxygenated fuels program and other control measures defined Tucson as
``Area B'', a carbon monoxide nonattainment area. ACLPI expressed
concern that the area, following redesignation, would no longer be
subject to these control measures and said that under the circumstances
EPA cannot conclude that the emission reductions from these programs
are permanent and enforceable.
Response: The Arizona legislature has acted to amend various
Arizona Statutes to expand the definition of Area B to include CO
maintenance areas. On May 18, 1999 Arizona Governor Hull signed into
law House Bill 2189 which amended Arizona statutes 41-796.01, 41-2121,
49-401.01, 49-402, 49-404, 49-454, 49-541 and 49-571 to ensure
continued implementation of committed SIP control measures in
maintenance areas.
All of these statutory amendments have been submitted as SIP
revisions and EPA in this notice is approving those SIP revisions. On
the basis of these statutory amendments, EPA believes that this comment
has been adequately addressed.
Comment: ACLPI questioned whether the assumption in the LMP option
that an area beginning the maintenance period at or below 85% of
exceedance levels will continue to meet the standard for another ten
years is applicable to the TAPA, given the growth that is projected for
the area.
ACLPI also questioned the LMP guidance waiver of the CAA's
requirement for a 10 year maintenance demonstration and also the fact
that under a LMP an emissions budget may be treated as essentially not
constraining for the length of the maintenance period. ACLPI made the
following arguments:
<bullet> With regard to the LMP's waiver of the maintenance
demonstration, the mere fact that air quality and CO emissions are at
or below 85% of exceedance levels does not assure that they will not
increase to above exceedance levels in less than 10 years.
<bullet> The fact that under the LMP there is no emissions budget
test for conformity purposes flagrantly violates EPA's own conformity
rules which explicitly apply the emission budget test to all
maintenance areas. There is no exception for areas that are at or below
85% of exceedance levels and EPA cannot amend or repeal rules with a
guidance document.
<bullet> There is no factual or scientific basis for presuming that
a motor vehicle emissions budget will not be constraining in a limited
maintenance area. The potential for emissions growth has nothing to do
with existing CO levels, but is driven by factors such as growth in
vehicle miles traveled (VMT), increases in vehicle trips and increased
congestion. In the Tucson area, VMT is almost doubling every 20 years,
and congestion is expected to significantly worsen. Continued
application of conformity rules is vital to ensuring that
transportation plans, programs and projects, and federal activities,
are consistent with maintenance of CO standards.
Response: The additional information provided by PAG included
projections extending to 2010 and 2020 for CO mobile source emissions,
vehicle miles traveled (VMT) and population growth, as well as
information on ambient air CO concentrations for the years 1990 through
1998. That information is contained in Tables 1 and 2 below. The full
text of the PAG letter and details on the sources used for these
projections are in the TSD accompanying the reproposal notice, which
may be found in the docket for this document.

----------------------------------------------------------------------------------------------------------------
EPA has reviewed the additional information provided by PAG and,
based on that data, has come to the following conclusions:
<bullet> Although there are projected increases in population and
vehicle miles traveled (VMT), the data indicates that CO emissions will
drop from 444.8 tons per day in 1990 to 367.2 in 2010, rising again to
a projected 428.7 tons per day in 2020 which is still below 1990
levels. In summary, despite the projected growth in population and VMT,
CO mobile source emissions in the TAPA will continue to decrease. The
decrease in projected CO emissions can be attributed to existing
control measures and the impacts of other programs that were not
included in the Mobile model used by PAG in preparing these projections
including the Pima Travel Reduction, Rideshare and Traffic Signal
Coordination programs. In addition it may be anticipated that national
mobile source control programs that will take effect in the future will
play a role in reducing CO emissions from mobile sources.
<bullet> According to data contained in Table 2, the design value
for the Tucson area for 1993-1995 was 6.0 or 67% of the NAAQs standard
for CO. The design value is the second highest eight-hour concentration
observed at any site in the area. The data also indicated that the
design value for the years 1996 through 1998 dropped to 5.1 or 57% of
CO NAAQS. EPA believes that these design values provide an ample margin
of safety and time to take action in the event of a possible violation
of the CO NAAQS in the future.
<bullet> EPA reviewed the projected CO mobile source emissions, VMT
and population values and the corresponding design values for the years
1990 through 1999 and concluded that it would be reasonable to assume
that the future relationship of these four elements would be comparable
through 2010.
<bullet> The control measures contained in the TAPA maintenance
plan are currently mandated by federal and state statutes and are
permanent and enforceable. They include the Federal Motor Vehicle
Control program, the State Inspection and Maintenance program and the
State Oxyfuels program. The Arizona legislature has amended the
statutes that had defined Tucson as a nonattainment area to ensure
continued implementation of SIP control measures following
redesignation to attainment. In addition, the Arizona legislature has
amended the statutes pertaining to the State's Vehicle Emission and
Inspection Program (VEIP) to assure continuation of the program through
December 31, 2008. With regard to the VEIP sunset date of 2008, which
is two years short of the ten-year maintenance period, in a letter to
EPA dated August 23, 1998, the Arizona Department of Environmental
Quality (ADEQ) states that Arizona Revised Statutes 41-2955 limits to
ten years the existence of a program before it undergoes a sunset
review and therefore the VEIP has been extended for the maximum time
allowed under this statute, i.e., ten years. The letter supplies a
recent history of legislative changes to the VEIP, concluding that
``The VEIP has consistently received support for necessary program
updates from the Legislature.'' EPA therefore believes that on the
basis of this legislative history, it is reasonable to assume that the
program will be extended when it expires in 2008. The full text of the
letter from ADEQ is attached to the TSD accompanying the reproposal.
<bullet> The maintenance plan for the TAPA contains a pre-violation
action level trigger which would set in motion a process designed to
forestall a future violation of the CO NAAQS. Under the plan, a pre-
violation action level would be reached when two verified 8-hour
average concentrations in excess of 85% of the CO NAAQS occurred at any
one monitor site in any CO season. When this criterion is reached, it
would trigger field studies and technical evaluations and
recommendations for implementation of contingency measures.
<bullet> With regard to the ACLPI's comments that: (1) The LMP
policy flagrantly violates EPA's own conformity rules which explicitly
apply the emission budget test to all maintenance areas; and (2) that
the rule does not provide an exception for areas that are at or below
85% of exceedance levels, EPA's conformity policy has clearly provided
for opportunities for a SIP to demonstrate that no budget is
[[Page 36356]]
needed (see Transportation Conformity Rule, 61 FR 36118, July 9, 1996,
paragraph B, finalized on August 15, 1997, 62 FR 43780). This section
addresses this question and mentions limited maintenance plans
specifically. The policy states that areas must meet budgets that the
SIP identifies, but if the SIP adequately justifies that no budget is
necessary, then no regional emissions test is necessary.
Comment: ACLPI contends that under section 175(A)(a) of the CAA a
maintenance plan must ``provide for'' and ``ensure'' maintenance for at
least 10 years. ACLPI said that EPA's LMP is based on mere speculation
and neither provides for, nor ensures, maintenance for ten years and is
therefore contrary to the CAA.
Response: The LMP guidance provides the rationale for the policy.
It states that ``EPA believes it is justifiable and appropriate to
apply a different set of maintenance plan requirements to
nonclassifiable CO nonattainment areas whose monitored air quality is
equal to or less than 85% of exceedance levels of the CO NAAQs. The EPA
does not believe that the full maintenance plan requirements need be
applied to these areas because they have achieved air quality levels
well below the standard without the application of control measures
required by the Act for moderate and serious nonattainment areas. Also,
these areas do not have either a recent history of monitored violations
of the CO NAAQS or a long prior history of monitored air quality
problems. EPA believes that the continued applicability of prevention
of significant deterioration (PSD) requirements, any control measures
already in the SIP, and Federal measures (such as the Federal motor
vehicle control program) should provide adequate assurance of
maintenance for these areas.''
EPA therefore believes that the LMP guidance considered the
requirements of 175(A)(a) of the CAA, and interpreted those
requirements in a manner consistent with the Act.
Comment: ACLPI expressed concern over the lack of clear commitments
to address actual violations of the CO standards. According to ACLPI,
the plan notes that state law gives ADEQ the option of reducing fuel
volatility levels and raising fuel oxygen content, but there is no
clear commitment from the state to take either of these steps if a
violation occurs. The plan also lists various potential control
measures that might be adopted to address future CO violations, but
does not commit to any of them.
ACLPI asked EPA to seek clarification from the state and PAG that
they are committed to adopt whatever additional controls are necessary
to correct an actual violation, and to implement such controls by the
start of the next CO season after the violation occurs. ACLPI claimed
that without such clarification the plan will not satisfy the
requirements of section 175A(d) to assure that any CO violation will be
promptly corrected.
Response: As requested, EPA sought clarification from PAG as to
whether they are committed to adopt whatever additional controls are
necessary to correct an actual violation of the CO NAAQS, and to
implement such controls by the start of the next CO season after the
violation occurs. The following is a summary of the points made in the
PAG response, dated November 19, 1998. The full text is contained in
the TSD accompanying the reproposal notice.
<bullet> The TAPA CO LMP was designed to set evaluation triggers at
a point where any violation of the CO NAAQS could be anticipated at
least 5 years ahead of time. This would give enough time to fully
evaluate the risk of violation and the best control measures to address
any projected violations of the standard.
<bullet> The TAPA CO LMP provides that in the event of an
exceedance (which must always precede a violation) the evaluation and
implementation process described in the Plan will be triggered. The
most likely control measure for immediate response is high oxygen
requirement in the oxyfuels program that can be implemented no later
than the following CO season.
<bullet> The TAPA plan provides that if the PAG finding indicates a
probable violation of the CO NAAQS within 5 years, the recommended
control measures to fully mitigate the projected violation must be
initiated by the start of the next CO season after the violation
occurs. EPA believes that the clarification of this issue provided by
PAG is an adequate response to the ACLPI comment.
In summary, EPA considered the population growth and CO emissions
projections provided by the PAG and the summary of the area's design
values over the past few years and believes that the data, in
conjunction with the pre-violation action triggers and the contingency
measures provided for in the TAPA maintenance plan, provide reasonable
assurance that the area will not violate the CO NAAQS during the
maintenance period. EPA is therefore taking final action to approve the
redesignation of the TAPA to attainment for the CO NAAQS and for
approval of the maintenance plan on the grounds that the area meets the
requirements for redesignation specified under the Clean Air Act, and
that the TAPA is qualified to utilize the LMP option.
III. Summary of Final Actions
In this action EPA is approving the following SIP revisions
relating to changes that were made in various Arizona statutes:
Amendments to A.R.S. 41-2083, 41-2122 and 41-2125 relating to the
State's oxyfuels program in the Tucson area both as SIP revisions and
as control measures in the maintenance plan to be implemented in the
event of a probable or actual violation of the CO NAAQS in the TAPA.
The SIP revision for these statutory amendments were submitted to EPA
as part of the TAPA maintenance plan on October 6, 1997 and were found
complete by operation of law on April 6, 1998.
Amendments to A.R.S. 49-401 and 49-406 which expand the authority
of State and local certified metropolitan planning organizations to
develop plans and to implement and enforce control measures for
attainment as well as maintenance areas as required by section
110(a)(2)(E) of the CAA. Previous to those statutory amendments, those
statutes referred only to nonattainment areas. These amendments were
signed into law on May 29, 1998. They were submitted as a SIP revision
on August 20, 1998 and were found complete by operation of law on
February 20, 1999.
Amendments to A.R.S. 41-796.01, 41-2121, 49-401.01, 49-402, 49-404,
49-454, 49-541 and 49-571 revised the definition of the TAPA
nonattainment area'' to reflect continued application of all pertinent
control measures in the TAPA following redesignation to attainment.
Prior to these amendments, these statutes referred to the TAPA as Area
B, a ``carbon monoxide nonattainment area''. These amendments were
signed into law on May 18, 1999. SIP revisions containing these
statutory amendments were submitted to EPA on September 1, 1999 and
were found to be complete on October 20, 1999.
Amendments to A.R.S. 41-3009.01, 49-541.01, 49-542, 49-545, 49-557,
49-573, 41-803, and 41-401.01 which were signed into law on May 18,
1999 relate to the continued implementation of the State's Vehicle
Emissions Inspection Program (VEIP) through December 31, 2008. The SIP
revisions containing these statutory amendments were submitted to EPA
on September 1, 1999 and were found to be complete on October 20, 1999.
[[Page 36357]]
EPA is approving the Emissions Inventory for the base year 1994
contained in the LMP as meeting the requirements of section 172(c)(3)
of the CAA.
EPA is approving the TAPA CO maintenance plan because it meets the
requirements set forth in section 175A of the CAA and the requirements
of the LMP option contained in EPA guidance of October 6, 1995.
EPA is taking final action to remove the Agency's disapprovals (56
FR 5459, February 11, 1991) of the attainment demonstration and
contingency measures that were contained in the 1988 Arizona CO SIP
revision for Pima County. Those disapprovals were based on the finding
of the Ninth Circuit Court of Appeals on March 1, 1990 in Delaney vs.
EPA, 898 F.2d 687, that the Arizona CO plans for Maricopa and Pima
Counties did not fully comply with the Clean Air Act as amended in
1977, and with EPA guidance issued pursuant to that law. (See 46 FR
7182, January 21, 1981). In vacating EPA's 1988 approval of the Arizona
plans, the court determined that they did not contain sufficient
control measures to attain the CO ambient air quality standard as soon
as possible. The Court did not say that the measures submitted by the
State were unworthy of approval for their effect in strengthening the
SIP.
EPA is taking final action to remove the attainment demonstration
disapproval because the TAPA has not had an exceedance of the CO NAAQS
from 1988 to the present, and, therefore, the original reason for the
disapproval, namely that the plan did not contain sufficient control
measures to attain the CO ambient air quality standard as soon as
possible, is no longer applicable.
EPA is also taking final action to remove the disapproval of the
1988 CO plan contingency measures. That disapproval was based on non-
compliance with the EPA guidance of January 21, 1981. (46 FR 7182,
January 21, 1981) That guidance has since been superseded by new
guidance, specifically the section on the contingency provisions for
not-classified CO nonattainment areas contained in the General Preamble
(See 57 FR 13535, April 16, 1992). The contingency provisions contained
in the TAPA Limited Maintenance Plan are in compliance with the
guidance provided both in the General Preamble and in the Limited
Maintenance Plan Policy Guidance.
Finally, EPA is approving Arizona's request for the redesignation
to attainment of the CO NAAQS for the Tucson Air Planning Area.
IV. Administrative Requirements
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
action is not a ``significant regulatory action'' and therefore is not
subject to review by the Office of Management and Budget. This action
merely approves state law as meeting federal requirements and imposes
no additional requirements beyond those imposed by state law.
Accordingly, the Administrator certifies that this rule will not have a
significant economic impact on a substantial number of small entities
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because
this rule approves pre-existing requirements under state law and does
not impose any additional enforceable duty beyond that required by
state law, it does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Public Law 104-4). For the same reason,
this rule also does not significantly or uniquely affect the
communities of tribal governments, as specified by Executive Order
13084 (63 FR 27655, May 10, 1998). This rule will not 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, as specified
in Executive Order 13132 (64 FR 43255, August 10, 1999), because it
merely approves a state rule implementing a federal standard, and does
not alter the relationship or the distribution of power and
responsibilities established in the Clean Air Act. This rule also is
not subject to Executive Order 13045 (62 FR 19885, April 23, 1997),
because it is not economically significant.
In reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act. In
this context, in the absence of a prior existing requirement for the
State to use voluntary consensus standards (VCS), EPA has no authority
to disapprove a SIP submission for failure to use VCS. It would thus be
inconsistent with applicable law for EPA, when it reviews a SIP
submission, to use VCS in place of a SIP submission that otherwise
satisfies the provisions of the Clean Air Act. Thus, the requirements
of section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (15 U.S.C. 272 note) do not apply. As required by section 3
of Executive Order 12988 (61 FR 4729, February 7, 1996), in issuing
this rule, EPA has taken the necessary steps to eliminate drafting
errors and ambiguity, minimize potential litigation, and provide a
clear legal standard for affected conduct. EPA has complied with
Executive Order 12630 (53 FR 8859, March 15, 1988) by examining the
takings implications of the rule in accordance with the ``Attorney
General's Supplemental Guidelines for the Evaluation of Risk and
Avoidance of Unanticipated Takings'' issued under the executive order.
This rule does not impose an information collection burden under the
provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et
seq.).
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this rule and other
required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. A major rule cannot
take effect until 60 days after it is published in the Federal
Register. This action is not a ``major rule'' as defined by 5 U.S.C.
804(2).
Under section 307(b)(1) of the Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by August 7, 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).)
