[CA-004-BU; FRL-5937-5]
Designation of Areas for Air Quality Planning Purposes; State of
California; Redesignation of the San Francisco Bay Area to
Nonattainment for Ozone
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: On May 22, 1995, EPA redesignated the San Francisco Bay Area
(Bay Area) from moderate nonattainment for the federal 1-hour ozone
standard to attainment (60 FR 27028). The redesignation became
effective on June 21, 1995. Two days later, the Bay Area experienced
its first violation of the federal 1-hour ozone standard as an
attainment area. There have been a total of 43 exceedances and 17
violations of the standard since redesignation. The Clean Air Act (CAA
or Act) provides that EPA may at any time notify the Governor that
available air quality information indicates that the designation of an
area within the State should be revised. EPA must consider the response
from the Governor as well as public comment on the proposed
redesignation before finalizing its action.
On August 21, 1997, EPA sent a letter to the Governor of California
notifying him of the Agency's intent to redesignate the Bay Area from
attainment to nonattainment of the federal 1-hour ozone standard. In
today's action, EPA is proposing to redesignate the Bay Area as a
nonattainment area for ozone.
DATES: Comments on this proposed action must be received in writing by
February 17, 1998. Comments should be addressed to the contact listed
below.
ADDRESSES: EPA's technical support document and other supporting
documentation for the proposal are contained in the docket for this
rulemaking. A copy of this document and the technical support document
are also available in the air programs section of EPA Region IX's
website, http://www.epa.gov/region09. The docket is available for
inspection during normal business hours at EPA Region IX, Planning
Office, Air Division, 17th Floor, 75 Hawthorne Street, San Francisco,

SUPPLEMENTARY INFORMATION:
I. Background
A. Original Designation
The Bay Area was originally designated under section 107 of the
1977 CAA as nonattainment for ozone on March 3, 1978 (40 CFR 81.305).
The Bay Area consists of the following counties: Alameda, Contra Costa,
Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano (part), and
Sonoma (part). Following the 1990 amendments to the Act, the area was
classified by operation
[[Page 66579]]
of law, under section 181(a), as a ``moderate'' nonattainment area. (56
FR 56694, November 6, 1991).
B. Redesignation to Attainment
On November 12, 1993, after three years without any violations of
the federal ozone standard according to quality assured ambient air
quality data from the official monitoring network 1 of the
Bay Area Air Quality Management District (Bay Area, District, or
BAAQMD), the California Air Resources Board (CARB) submitted to EPA for
approval a maintenance plan and a request to redesignate the Bay Area
ozone nonattainment area to attainment. On September 28, 1994, EPA
proposed to approve the State of California's submittal (59 FR 49361).
On May 22, 1995, EPA published the final rule redesignating the Bay
Area to attainment for ozone (60 FR 27028). The redesignation to
attainment became effective on June 21, 1995.
---------------------------------------------------------------------------
\1\ There were no monitored violations of the federal ozone
standard at the District's official State and Local Air Monitoring
Station (SLAMS) network monitors. There were, however, two
violations at special purpose monitors (SPMs) that were established
for research purposes. EPA was aware of these violations at the time
it redesignated the area to attainment. However, EPA excluded these
data because the monitors were not part of the official monitoring
network and were not intended to monitor ambient air quality for
federal compliance purposes. For policy reasons, EPA did not want to
discourage the Bay Area, or other areas, from establishing monitors
for research purposes. EPA has since determined that all quality
assured data that meet the requirements of 40 CFR 58.14, with the
exception of fine particulate matter data (PM-2.5), must be
considered for any regulatory purpose, including an ozone
redesignation action. (August 22, 1997 memorandum entitled, ``Agency
Policy on the Use of Special Purpose Monitoring Data,'' from John
Seitz, Director of the Office of Air Quality Planning and Standards,
to Air Division Directors, EPA Regions I-X) While EPA has determined
that the SPMs data should have been considered in the 1995
redesignation action, the Agency is not basing today's proposed
action on these data. Today's action is based on the 17 violations
recorded during 1995 and 1996.
---------------------------------------------------------------------------
C. Violations of the Ozone Standard After Redesignation
Despite implementation of most of the measures in the Bay Area's
maintenance plan, the Bay Area's monitoring network 2 has
recorded 46 exceedances (43 since the redesignation to attainment in
June 1995) and 17 violations of the federal 1-hour ozone standard over
the 3-year period 1994-1996.3
---------------------------------------------------------------------------
\2\ Air quality in the Bay Area is monitored by the District's
State and Local Air Monitoring Station (SLAMS) network, which
comprises 24 monitoring stations. All data must be quality assured.
\3\ As required by section 175A of the Act, the Bay Area
maintenance plan contains contingency measures that should be
designed to correct any violation of the standard occurring after
redesignation to attainment. The Bay Area maintenance plan contains
six equipment-specific NOx controls and several improvements to the
federally mandated Basic Inspection and Maintenance Program (I/M).
While the District is continuing to implement the contingency
measures in its maintenance plan, the remaining emission reductions
to be gained from these measures total 1.2 tons per day in NOx
reductions and almost no reductions of Volatile Organic Compounds
(VOCs).
---------------------------------------------------------------------------
An exceedance of the 1-hour ozone standard occurs when the hourly
average ozone concentration at a given monitoring site is greater than
or equal to .125 ppm. A violation of the standard occurs when the
expected number of days per calendar year with maximum hourly average
ozone concentrations above 0.12 ppm is greater than one. 40 CFR part
50.9. The average number of days is calculated for a 3-year period. 40
CFR part 50, appendix H. This 3-year period was established to reduce
the impact of yearly fluctuations in ozone levels. Table 1 lists both
the exceedances and the 3-year average number of days over the 1-hour
ozone standard for each SLAMS monitoring site in the Bay Area for the
period 1994-1996.

D. Petitions to the Administrator
EPA has received two petitions requesting that the Administrator
redesignate the Bay Area to nonattainment with the federal 1-hour ozone
standard. On March 31, 1997, the Sierra Club and Communities for a
Better Environment requested that EPA withdraw the 1995 redesignation
action, or alternatively redesignate the area to nonattainment. The
Sierra Club also requested that EPA issue a section 110(k)(5) SIP call
based on the inadequacy of the current SIP.4 On July 14,
1997, U.S. Congressman Gary Condit and a coalition of federal, state
and local elected officials and public interest and industry groups
from downwind areas (primarily the San Joaquin Valley) also requested
that EPA withdraw the 1995 redesignation to attainment, or
alternatively redesignate the area to nonattainment and issue a SIP
call.
---------------------------------------------------------------------------
\4\ A SIP call is a determination under section 110(k)(5) of the
Clean Air Act that the SIP is inadequate and must be revised.
---------------------------------------------------------------------------
E. Applicable Statutory Provisions
Section 107(d)(3) of the Act gives the Administrator the authority
to redesignate areas. Under this provision, the Administrator may
``(O)n the basis of air quality data, planning and control
considerations, or any other air quality-related considerations the
Administrator deems appropriate, * * * at any time notify the Governor
of any State that available information indicates that the designation
of any area * * * should be revised.'' Section 107(d)(3)(A). The
Governor then has 120 days to submit the redesignation, as the Governor
considers appropriate. Section 107(d)(3)(B). The Administrator must
promulgate the redesignation within 120 days of the Governor's
response. The Administrator may make any modifications to the
Governor's redesignation which she deems necessary, but must notify the
Governor of such changes 60 days before promulgating a final
redesignation. If the Governor does not submit the redesignation, the
Administrator shall promulgate the redesignation which she deems
appropriate. Section 107(d)(3)(C). EPA notified the Governor of
California by letter dated August 21, 1997, that EPA believes that,
based on air quality data, the Bay Area should be redesignated to
nonattainment.5 The
[[Page 66580]]
Governor must respond to this letter by December 19, 1997.
---------------------------------------------------------------------------
\5\ This letter is available to the public as part of the docket
for this rulemaking action. While EPA indicated in this letter that
the Bay Area would be classified as ``moderate,'' the Agency has
determined that a moderate classification is not necessary under
subpart 1 of the Act. (See discussion at II.A.) Furthermore, the
planning requirement to prepare a modeling plan for the 8-hour ozone
standard will no longer be required as the District is already
engaged in such an exercise with the California Air Resources Board
and downwind air districts.
---------------------------------------------------------------------------
F. Proposed Action
In today's document, EPA proposes to redesignate the San Francisco
Bay Area to nonattainment for the 1-hour ozone NAAQS because ozone
levels have violated the federal standard 17 times over the three year
period 1994-1996. Today's action further proposes to require the Bay
Area to develop and submit a SIP revision designed to demonstrate
attainment of the 1-hour ozone NAAQS by November 15, 1999. Finally,
today's action proposes an amendment to 40 CFR parts 52 and 81 to
reflect the change in designation. These actions are proposed in
accordance with sections 107(d), 110, and 172 of the CAA.
II. Applicable Plan Requirements
A. Clean Air Act Provisions
The classifications and attainment dates for areas classified
nonattainment under the 1990 amendments to the Act are contained in
section 181(a). The provisions for new designations to nonattainment
are found in subsection (b)(1). This subsection provides that areas
that were attainment or unclassifiable at the time of the 1990
amendments and are subsequently redesignated to nonattainment are to be
classified according to the table in section 181(a)(1). This language
contains no reference to areas that were designated nonattainment as a
result of the 1990 amendments.
For areas that were designated attainment or unclassifiable
following the 1990 amendments, this section further provides that such
areas are subject to the same requirements of section 110 and subparts
1 and 2 of the Act as areas designated nonattainment pursuant to the
1990 amendments. In addition, these areas are given an extension of all
fixed date deadlines equal to the length of time between November 15,
1990, and the date the area is redesignated.
Although section 181(b)(1) deals with designations to nonattainment
occurring after the initial round of classifications under the 1990
amendments, it does not address areas, such as the Bay Area, that were
designated nonattainment under the amendments, redesignated to
attainment, and that subsequently fall out of attainment and are
redesignated back to nonattainment. Because this provision does not, on
its face, apply to areas like the Bay Area, EPA believes that it has
discretion to determine whether such areas should fall under subpart 2
of the Act when they are redesignated to nonattainment, or should only
be subject to the more general provisions of subpart 1.
EPA believes the latter is the appropriate result for a number of
reasons. First, the plain language of section 181(b)(1) of the statute
applies only to areas designated attainment under section 107(d)(4) and
excludes areas like the Bay Area. Second, it is logical to grant the
generous extension of deadlines to areas that have never been
nonattainment and must devise their first nonattainment area SIPs.
Conversely, an area that was previously designated as nonattainment has
already done much of this work and should not need this lengthy time
period to complete its planning process. Moreover, areas such as the
Bay Area generally will have already implemented the section 181
requirements applicable to their previous classification (moderate,
serious, severe or extreme). Assuming that these requirements continue
to be implemented, placing the area back into the section 181 scheme
would do little to bring the area back into attainment. On the other
hand, placing the area under section 172 provides the flexibility for
the area to identify a new mix of measures that, when combined with
those already implemented under section 181, will bring the area back
into attainment. Finally, sections 172(a)(1) and (2) contain express
statements that they do not apply to nonattainment areas that are
specifically covered by other provisions of part D of the Act, thereby
demonstrating that the Act contemplates that some areas will fall under
subpart 1, rather than subpart 2. See sections 172(a)(1)(C) and
(a)(2)(D). For these reasons, EPA believes the best interpretation of
the Act is that it intentionally excludes areas like the Bay Area from
section 181 and places them under section 172.
B. Section 172 Requirements
General nonattainment plan requirements are contained in section
172(c). Section 172(b) requires the Bay Area plan to meet the
``applicable'' requirements of section 172(c). For reasons set forth
below, we believe that some of the section 172(c) requirements have
already been satisfied and therefore need not be part of the plan
revisions the Bay Area would be required to submit under this proposed
action. A table containing the proposed submittals and submittal dates
is located at the end of section II.D. below.
Section 172(c)(1) requires that the plan provide for implementation
of all reasonably available control measures (RACM) as expeditiously as
practicable, including emission reductions from existing sources
through adoption of reasonably available control technology (RACT).
This provision is applicable to the Bay Area only to the extent that it
has not already been complied with. EPA believes that the Bay Area
implemented all VOC RACT and most, if not all, oxides of nitrogen
(NOX) RACT measures prior to being redesignated to
attainment in 1995.6 60 FR 27028.
---------------------------------------------------------------------------
\6\ The Bay Area requested and received a NOx waiver
pursuant to section 182(f) of the Act. 60 FR 27028, May 22, 1995.
The waiver was based on 3 years of clean ambient air quality data
showing that ozone attainment was achieved without application of
the section 182(f) NOx control requirements. Since the
waivers only apply to nonattainment areas, they remain in effect
only during the period before redesignation of the area to
attainment under section 107(d)(3). Thus, when the Bay Area's
redesignation to attainment became effective on June 21, 1995,
precursor emissions, like NOx, were addressed, as
appropriate, under terms of the Bay Area maintenance plan. It is
clear, upon final redesignation of the Bay Area to nonattainment
based on subsequent violations of the ozone NAAQS, that the basis
for granting the original NOx waiver no longer exists.
---------------------------------------------------------------------------
As required by section 172(c)(1), the plan must provide for
attainment. Generally, new modeling is required in order to demonstrate
that a plan will indeed provide for attainment. During the stakeholder
process that preceded the Agency's decision to propose redesignation
EPA heard two points made fairly consistently by all those involved.
First, all parties agreed on the importance of a new field study and
modeling effort in order to better understand the ozone problem in the
Bay Area, as well as its effects on downwind areas. Second, the parties
agreed that it would be impossible to conduct a new field study and
modeling effort for a short term plan, particularly in light of the
fact that the Bay Area will be required to undertake such an effort for
the new 8-hour standard if designated nonattainment for the 8-hour
standard.
In response to public input, EPA is proposing to require an
assessment, employing available modeling information, of the level of
emission reductions needed to attain the 1-hour ozone NAAQS. The
assessment should take into account the meteorological conditions and
ambient concentrations associated with the ozone violations in 1995 and
1996, and should be based on likely control measures for reducing VOC
and NOx emissions. This work may include previous
photochemical modeling that was based on Bay Area's 1989 field study,
the 1990 modeling analysis done for the San Joaquin Valley, modeling
conducted for Bay Area's SIP attainment demonstration
[[Page 66581]]
that was based on the Empirical Kinetic Modeling Approach [EKMA], and
any other work that will lend insight into the nature of the ozone
problem in the Bay Area. It may be appropriate to form a committee made
up of representatives with technical modeling expertise from the
BAAQMD, CARB, and EPA to review the analysis. EPA recommends that the
committee also include technical staff from downwind districts. EPA is
proposing that this assessment be submitted on May 1, 1998.
Section 172(c)(2) contains the requirement for reasonable further
progress (RFP). RFP is defined as ``such annual incremental reductions
in emissions * * * as are required by this part or may reasonably be
required by the Administrator for the purpose of ensuring attainment *
* * by the applicable date.'' Section 171(1). Because EPA is not
proposing to require submission of adopted measures until September
1998, the Agency believes that the RFP requirement would be satisfied
if all required emission reductions occur by 1999, the proposed
attainment year.
Under section 172(c)(3) the Bay Area must submit a comprehensive,
accurate, and current inventory of actual emissions from all sources.
To address this requirement, EPA proposes that the Bay Area must submit
a current and complete baseline annual average and summer weekday and
weekend day 7 emissions inventory for VOC, NOx,
and carbon monoxide (CO). This submittal would be due on May 1, 1998.
---------------------------------------------------------------------------
\7\ EPA Guidance Document #EPA-450-4-91-014, entitled
``Preparation of Emissions for CO and Ozone Precursors for Air
Quality Modeling,'' Volume II, May 1991.
---------------------------------------------------------------------------
Section 172(c)(4) requires the area to identify and quantify
emissions that will be allowed from new major sources or major
modifications in urban enterprise zones identified by the Administrator
in consultation with the Secretary of Housing and Urban Development
under section 173(a)(1)(B) of the Act. No such zones have been
identified in the Bay Area nonattainment area. Thus, no submission is
required for this plan. Were such zones to be identified, a growth
allowance would have to be included in the SIP to ensure that emission
increases from new sources in the urban enterprize zones would not
interfere with attainment.
Section 172(c)(5) requires submittal of a new source review (NSR)
program consistent with section 173 of the Act. While the Bay Area does
have a SIP-approved NSR program, it is out of date and does not meet
current statutory requirements.\8\ The Bay Area has submitted a revised
new source review rule designed to meet the requirements of the 1990
amendments to the Act. EPA will act on this rule and the NSR
requirement in separate rulemaking. Based on the Bay Area's design
value of .138 ppm, EPA believes that the NSR program should, by
analogy, meet the requirements applicable to a moderate area. Thus, we
are proposing that the NSR permitting requirements, applicability
thresholds, and offset ratios be set at the same levels that apply to
moderate ozone nonattainment areas under sections 182(a)(2)(C) and
182(b)(5).
---------------------------------------------------------------------------
\8\ See 54 FR 11866 (March 19, 1982).
---------------------------------------------------------------------------
Section 172(c)(6) requires enforceable emission limitations and
other control measures, means or techniques, necessary to provide for
attainment by the applicable date. We are proposing that the Bay Area
submit by September 1, 1998, adopted regulations (and/or enforceable
commitments to adopt and implement control measures in regulatory form
by specified dates) sufficient to attain the 1-hour ozone NAAQS by
November 15, 1999. Section 172(c)(6) allows the Bay Area to identify
and adopt a mix of measures that best meets the needs of the area.
Section 172(c)(7) requires that nonattainment plans meet the
general SIP requirements of section 110(a)(2).
Section 172(c)(8) allows the District to apply to the Administrator
to use equivalent modeling, emission inventory, and planning
procedures.
Under section 172(c)(9), a plan must contain contingency measures
that go into effect if the area fails to make RFP or fails to attain
the standard. The Bay Area plan will need to contain contingency
measures that go into effect if the area is unable to attain the 1-hour
ozone NAAQS by the attainment date. As discussed above, the short
attainment period for the Bay Area means that failure to make RFP and
failure to attain are equivalent.
C. Applicable Attainment Date
Section 172(a)(2) governs attainment dates for nonattainment areas
that fall under section 172. This section provides that the attainment
date for an area designated nonattainment shall be as expeditiously as
practicable, but no later than 5 years from the date the area is
designated nonattainment. Thus, the Administrator may set the
attainment date at any point up to 5 years based on an assessment of
what is ``as expeditiously as practicable.''
Because the Bay Area's emissions appear to be on a downward trend
based on currently available information,9 and because the
area was attaining the standard as recently as 1994, EPA believes that
the Bay Area should be able to identify and implement measures that
will bring it back into attainment fairly quickly. Thus, EPA is
proposing to set the Bay Area's attainment deadline as November 15,
1999. This is the date by which the area would have had to attain if it
had been bumped up to a ``serious'' classification rather than being
redesignated to attainment. As discussed above, the Bay Area recorded
43 exceedances and 17 violations of the standard from June 21, 1995
(the date on which the area was redesignated to attainment) and
November 15, 1996, the attainment deadline for moderate ozone
nonattainment areas. These violations far exceed those recorded during
the same time frame by other moderate ozone nonattainment areas which
EPA is proposing to bump up to serious for failure to attain by
November 15, 1996.
---------------------------------------------------------------------------
\9\ ``Bay Area Emission Inventory Projections: 1980-2002,''
provided by the Bay Area to EPA May 1997.
---------------------------------------------------------------------------
EPA proposes to make the determination as to whether the area has
attained based on monitoring data from the years 1997, 1998 and 1999.
During this time frame, EPA will be reviewing 1997-1999 monitoring data
for the entire country to determine whether areas are violating the new
NAAQS. Areas that violate the 8-hour standard but attain the 1-hour
standard prior to designation under the new standard will be eligible
for classification as a ``transitional'' area when designated
nonattainment for the new 8-hour NAAQS.10 If the Bay Area
attains the 1-hour standard by 1999 and meets the requirements for
transitional areas, it may take advantage of this status and avoid
certain enumerated requirements under the new NAAQS.
---------------------------------------------------------------------------
\10\ 62 FR 38426, July 18, 1997.
---------------------------------------------------------------------------
In the event that the Bay Area does not meet the 1999 attainment
date, it may, in the future, be eligible for up to two 1-year
extensions of this date if it were to meet the requirements of section
172(a)(2)(C).
EPA is particularly interested in receiving public comment on the
proposed November 15, 1999 attainment deadline. The Agency has received
preliminary input from the District indicating that it believes a later
date should be chosen. EPA solicits comment from all interested parties
on this issue.
D. Schedule for Plan Submissions
The schedule for plan submissions is governed by section 172(b).
This section
[[Page 66582]]
provides that the Administrator must establish a schedule for each area
to submit a plan or plan revision that meets the applicable
requirements of sections 172(c) and 110(a)(2). The schedule must, at a
minimum, require submission of the attainment plan no later than three
years after designation to nonattainment. EPA is proposing two separate
submittal dates for elements of the Bay Area plan that are designed to
achieve the November 15, 1999 attainment date. These submittals will be
due on May 1, 1998 and September 1, 1998. The contents of these
submittals are discussed in section II.B. above.

III. Administrative Requirements
A. Executive Order (E.O.) 12866
Under E.O. 12866, (58 FR 51735, October 4, 1993), EPA is required
to determine whether today's proposal is a ``significant regulatory
action'' within the meaning of the E.O., and therefore should be
subject to OMB review, economic analysis, and the requirements of the
E.O. See E.O. 12866, Sec. 6(a)(3). The E.O. defines, in Sec. 3(f), a
``significant regulatory action'' as a regulatory action that is likely
to result in a rule that may meet at least one of four criteria
identified in section 3(f), including,
(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.
EPA has determined that the redesignation to nonattainment proposed
today, as well as the establishment of SIP submittal schedules, would
result in none of the effects identified in E.O. 12866 Sec. 3(f). Under
section 107(d)(3) of the Act, redesignations to nonattainment are based
upon air quality considerations. The finding, based on air quality
data, that the Bay Area is not attaining the ozone NAAQS and should be
redesignated to nonattainment does not, in and of itself, impose any
new requirements on any sectors of the economy. Similarly, the
establishment of new SIP submittal schedules merely establishes the
dates by which SIPs must be submitted, and does not adversely affect
entities.
B. Regulatory Flexibility
Under the Regulatory Flexibility Act, 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.
Alternatively, EPA may certify that the rule will not have a
significant economic 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.
A redesignation to nonattainment under section 107(d)(3), and the
establishment of a SIP submittal schedule for a reclassified area, do
not, in and of themselves, 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 rulemaking simply proposes to make a factual
determination and to establish a schedule to require the State to
submit SIP revisions, and does not propose to directly regulate any
entities. Because EPA is proposing to apply the same permitting
applicability thresholds and offset ratios applicable to moderate
areas, no additional sources will be subject to these requirements as a
result of EPA's action. Therefore, pursuant to 5 U.S.C. 605(b), EPA
certifies that today's proposed action does not have a significant
impact on a substantial number of small entities within the meaning of
those terms for RFA purposes.
C. Unfunded Mandates Reform Act
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 the UMRA, EPA
generally must prepare a written statement, including a cost-benefit
analysis, when EPA promulgates ``any general notice of proposed
rulemaking that is likely to result in promulgation of any rule that
includes any Federal mandate that may result in the expenditures by
State, local, and tribal governments, in the aggregate, or by the
private sector, of $100 million or more'' in any one year. A ``Federal
mandate'' is defined, under section 101 of UMRA, as a provision that
``would impose an enforceable duty'' upon the private sector or State,
local, or tribal governments,'' with certain exceptions not here
relevant. Under section 203 of UMRA, EPA must develop a small
government agency plan before EPA ``establish[es] any regulatory
requirements that might significantly or uniquely affect small
governments.'' Under section 204 of UMRA, EPA is required to develop a
process to facilitate input by elected officers of State, local, and
tribal governments for EPA's ``regulatory proposals'' that contain
significant Federal intergovernmental mandates. Under section 205 of
UMRA, before EPA promulgates ``any rule for which a written statement
is required under [UMRA sec.] 202'', EPA must identify and consider a
reasonable number of regulatory alternatives and either adopt the least
costly, most cost-effective or least burdensome alternative that
achieves the objectives of the rule, or explain why a different
alternative was selected.
EPA has concluded that this proposed rule is not likely to result
in the promulgation of any Federal mandate
[[Page 66583]]
that may result in expenditures of $100 million or more for State,
local or tribal governments in the aggregate, or for the private
sector, in any one year. It is questionable whether a redesignation
would constitute a federal mandate in any case. The obligation for the
state to revise its State Implementation Plan that arises out of a
redesignation is not legally enforceable and at most is a condition for
continued receipt of federal highway funds. Therefore, it does not
appear that such an action creates any enforceable duty within the
meaning of section 421(5)(a)(i) of UMRA (2 U.S.C. 658(5)(a)(i)), and if
it does the duty would appear to fall within the exception for a
condition of Federal assistance under section 421(5)(a)(i)(I) of UMRA
(2 U.S.C. 658(5)(a)(i)(I)).
Even if a redesignation were considered a Federal mandate, the
anticipated costs resulting from the mandate would not exceed $100
million to either the private sector or state, local and tribal
governments. Redesignation of an area to nonattainment does not, in
itself, impose any mandates or costs on the private sector, and thus,
there is no private sector mandate within the meaning of section 421(7)
of UMRA (2 U.S.C. 658(7)). The only cost resulting from the
redesignation itself is the cost to the State of California of
developing, adopting and submitting any necessary SIP revision. Because
that cost will not exceed $100 million, this proposal (if it is a
federal mandate at all) is not subject to the requirements of sections
202 and 205 of UMRA (2 U.S.C. 1532 and 1535). EPA has also determined
that this proposal would not result in regulatory requirements that
might significantly or uniquely affect small governments because only
the State would take any action as result of today's rule, and thus the
requirements of section 203 (2 U.S.C. 1533) do not apply.
