[OH-138-2; FRL-6914-7]
Approval and Promulgation of Implementation Plans and Designation
of Areas for Air Quality Planning Purposes; Ohio
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is redesignating Cuyahoga and Jefferson Counties, Ohio, to
attainment for particulate matter nominally 10 microns in aerodynamic
diameter and smaller (PM10). EPA is also approving Ohio's plan for
maintaining air quality at levels below the applicable air quality
standards.
EPA proposed these actions on July 10, 2000. One commenter
submitted numerous comments, generally taking the position that the
criteria for redesignation to attainment given in Clean Air Act section
107(d)(3)(E) are not met. EPA has reviewed these comments and, for the
reasons set forth below, continues to believe that the redesignation
criteria have been met and that these areas may be redesignated and
their maintenance plans approved.
The Steubenville area includes portions of Brooke County, West
Virginia, as well as Jefferson County, Ohio. For administrative
convenience EPA is taking action only on the Ohio portion of this area.
Nevertheless, the action reflects review of air quality for the entire
area and Ohio's fulfillment of its portion of an area-wide attainment
plan that it developed jointly with West Virginia. In the future, if
the standard is violated in either portion of the area, such that
redesignation back to nonattainment is warranted, EPA will propose to
reinstate nonattainment status for the entire area.
EFFECTIVE DATE: This action will be effective on January 10, 2001.
ADDRESSES: Copies of the Ohio's submittals and other information are
available for inspection during normal business hours at the following

I. What Actions Did EPA Propose, and Why?
On July 10, 2000, EPA published rulemaking proposing to approve a
maintenance plan and redesignation of Cuyahoga and Jefferson Counties,
Ohio, to attainment for particulate matter, specifically for particles
known as PM10. (See 65 FR 43212.) This proposal was based on
a request from the State of Ohio submitted in preliminary form on May
22, 2000. This action pertains to the PM10 standards
promulgated in 1987 at 40 CFR 50.6, for which designations are
published at 40 CFR 81. This action does not pertain to the
PM10 standards promulgated in 1997 at 40 CFR 50.7, which
have been vacated by the District of Columbia Circuit Court of Appeals
and for which no designations have been published.
Ohio's maintenance plan relies predominantly on the emissions
limits already included in its State Implementation Plan (SIP) that
have been shown to limit emissions from the significant sources in
these areas sufficiently to assure attainment. The attainment plan
addresses maximum allowable emissions, so the plan provides for
continued attainment even if source production rates grow to maximum
capacity. Ohio's maintenance plan supplements this with evidence of
declining impacts from other, unregulated sources, which contribute to
the background concentration included in the attainment demonstration.
Specifically, Ohio cited population declines in the two counties, which
will lead to reduced emissions from consumer activities, and federal
regulations requiring reduced emissions from diesel engines. Ohio
further cited emission regulations which will reduce emissions below
attainment levels at the coke batteries found in the two areas. EPA
proposed to conclude on the basis of these plan elements that these
counties can be expected to continue attaining the applicable
PM10 standards for the requisite 10 years.
EPA reviewed Ohio's redesignation request on the basis of five
criteria given in section 107(d)(3)(E) of the Clean Air Act. The first
criterion is attainment of the air quality standards. All monitors have
annual average concentrations below the annual standard. The 24-hour
standard is met if the expected frequency of values above 150
g/m3 is 1.0 day per year or less. All the monitors
in the Steubenville area and most of the monitors in Cuyahoga County
have recorded no recent exceedances of this air quality standard. These
monitors clearly indicate attainment of these standards. Two monitors
in Cleveland have recorded values above 150 g/m3,
requiring analysis of expected exceedances at these locations
consistent with the provisions of Appendix K of 40 CFR 50. EPA found a
sufficiently low expected frequency of exceedances to propose to
conclude that these locations, like the rest of Cuyahoga County, are
attaining the standards.
The second criterion is that EPA has fully approved the necessary
air quality control plans. EPA has previously concluded that relevant
requirements were met, as stated in rulemakings published on May 27,
1994, at 59 FR 27464, and June 12, 1996, at 61 FR 29662, supplementing
earlier rulemakings. In acting on redesignation requests, EPA has
consistently interpreted section 107(d)(3) as permitting the Agency to
rely on prior approvals of SIP provisions when reviewing redesignation
requests. See Memorandum from John Calcagni, Director of the Air
Quality Management Division dated September 4, 1992. For a recent
discussion of redesignation requirements see 65 FR 37879 (June 19,
2000) (redesignation to attainment for ozone of the Cincinnati-Hamilton
moderate ozone nonattainment area).
The third criterion for redesignation is that attainment be
attributable to permanent and enforceable emission reductions. EPA
found that permanent and enforceable emission limits have yielded
permanent emission reductions that satisfied this criterion at numerous
facilities in the two counties. The fourth criterion is that EPA has
approved a maintenance plan that assures continued attainment. As
discussed above, EPA proposed to approve Ohio's maintenance plan. Final
approval of this plan, which is part of today's action, completes the
satisfaction of this criterion. The fifth criterion is that the State
be found to have met applicable requirements of section 110 and Part D
of the Clean Air Act. Based on various rulemakings, starting with
rulemaking of April 15, 1974 (39 FR 13539) up to and including EPA's
rulemaking of June 12, 1996 (61 FR 29662), EPA finds that the State met
these requirements. In summary, EPA proposed to find that Ohio had met
all five criteria for redesignation for PM 10 in Cuyahoga
and Jefferson Counties, and so EPA proposed to redesignate these
counties to attainment.
II. What Comments Did We Receive and What Are Our Responses?
EPA received comments from one commenter, the Earthjustice Legal
Defense Fund, representing the Ohio Chapter of the Sierra Club. These
comments are organized according to the five criteria for redesignation
listed above. The following comment summaries and EPA responses are
organized accordingly.
1. Attainment
Comment: The commenter cites EPA's Air Information Retrieval System
(AIRS) database as showing that one of the monitoring sites, at East
14th Street and Orange Avenue in Cleveland, ``had 6 expected
exceedances of the 24 hour PM 10 standard in 1999. Moreover,
AIRS data shows that the same monitor has recorded 6 expected
exceedances so far in the year 2000.'' The commenter states that the
total of 12 expected exceedances at this site means that the area has
not attained the standard.
The commenter further states that ``EPA seeks to discount the 6
expected exceedances in 1999 at [the above site] by citing data from
other monitors that did not exceed the standard that year.'' The
commenter states that disregarding violations based on data at other
sites is not authorized in Appendix K, and EPA may not use guidance
documents to amend Appendix K to grant itself this authority.
Response: The commenter summarizes air quality at the East 14th
Street site by reporting a statistic from a summary of air quality data
that EPA provides on the internet. By its nature, this summary
statistic is derived by an oversimplified approach, and thus
inaccurately reflects what the data show. This statistic in this
context is derived by automated, default procedures that cannot make
the case-by-case judgments involved in assessing attainment status for
regulatory purposes. For example, the statistic that the commenter
cites does not reflect judgments that must be made by EPA, such as
whether to exempt the site from expected exceedance adjustments
pursuant to Appendix K section 3.1(f) and 40 CFR 58.13. A more
appropriate evaluation of the 1999 data at this site is presented in
the notice of proposed rulemaking. This evaluation indicates that only
approximately one exceedance is expected at that location. A similar
evaluation of the 2000 data at this site, as described further below,
also indicates approximately one exceedance is expected. Based on these
data, EPA is determining that the 3-year average number of expected
exceedances at this site is less than the 1.0 level, and thus the site
is in attainment consistent with section 2.1 of Appendix K.
It is also apparent that the commenter may have misunderstood the
discussion in the proposal relating to the
[[Page 77310]]
historically worst-case site that adjoins the East 14th Street site.
Contrary to the assertion in the comment, EPA is not using data from
other monitors to discount a violation at the East 14th Street site.
Instead, EPA is assessing whether a violation in fact occurred at the
East 14th Street site.
The East 14th Street site has two instruments--a high volume
sampler, taking samples once every six days, and an instrument that
takes continuous concentration readings. The high volume sampler
recorded an exceedance of the 24-hour PM10 standard at this
site in 1999 (as well as an exceedance in 2000). EPA's evaluation of
these high volume sampler data appropriately considers data from the
collocated continuous instrument as well as data from another nearby
location. Specifically, EPA is using the additional data to evaluate
the likelihood of exceedances on the other five out of six days on
which the high volume sampler did not take measurements.
One element of EPA's evaluation is based on Appendix K section
3.1(f), for which EPA must consider whether everyday sampling has been
conducted in accordance with 40 CFR 58.13. In 40 CFR 58.13, as it
applies to sampling for this PM10 standard, EPA calls for
everyday sampling at the area of maximum concentration. Accordingly,
the notice of proposed rulemaking describes an assessment in which the
application of Appendix K section 3.1(f) to the East 14th Street site
is contingent on daily sampling at a nearby, maximum concentration
site. As discussed in the notice of proposed rulemaking, application of
Appendix K section 3.1(f) contingent on daily sampling at the East 14th
Street site yields the same result. Both methods lead to treating the
measured exceedance as one expected exceedance, which leads to a
finding that the standard is being attained.
When EPA promulgated Appendix K, it was concerned, in part, about
how to appropriately interpret data from monitors taking measurements
one day out of six days when they measure just one exceedance. EPA
recognized that the occasional measurement of one exceedance by such
monitors often does not signify that five other exceedances would be
expected to occur on the unmonitored days. Therefore, section 3.1(f) of
Appendix K provides that an adjustment, that entails treating one
exceedance as reflecting six (or more) expected exceedances (which is
otherwise required to account for missing or incomplete data), need not
be done if complete daily, representative sampling is performed and
related conditions are met. If complete daily, representative sampling
then shows few or no exceedances, this would validate the view that the
exceedance measured during one-in-six-day sampling is better
interpreted as reflecting one rather than six (or more) expected
exceedances. (Conversely, if daily sampling indicates frequent
exceedances, EPA would have a more solid basis for concluding that the
site is not attaining.)
The monitoring at the East 14th Street site poses unique
circumstances not directly addressed in Appendix K. Appendix K does not
specify how to interpret data from two instruments which measure air
quality at the same location. EPA has issued guidance explaining how to
assess expected exceedances for both instruments in such cases.
However, neither Appendix K nor EPA's guidance specifies how to conduct
this assessment in cases where the sampling frequencies of the two
instruments differ.
The history of Appendix K helps clarify why it does not directly
address the situation found at the East 14th Street site. Appendix K
was promulgated in 1987, at a time when reliable continuous instruments
for measuring particulate matter concentrations were not available.
Since high volume sampling and filter collection and analysis on a
daily basis is resource intensive, EPA encouraged States to conduct
sampling once every six days at numerous sites, with only a small
number of critical sites sampling on a daily basis. When it encouraged
this approach, EPA did not intend that any sampler measuring once every
six days that happened to record an exceedance would automatically be
treated as showing nonattainment, which is the approach reflected in
the commenter's interpretation of the air quality data summary posted
on the internet. EPA intended instead that such sampling sites be
identified as critical sites warranting the dedication of resources
necessary to conduct daily sampling, in order to determine whether the
exceedance recurs with a frequency of more than once per year.
In promulgating Appendix K, EPA did not anticipate the possibility
that States might simultaneously operate one sampler on a once in six
days basis and operate a second sampler at the same site on a daily
basis. Even today, sites with instruments measuring air quality once
every six days almost never have a collocated instrument simultaneously
taking daily or continuous measurements. Therefore, the one-in-six-day
data are ordinarily the only basis on which to estimate the likelihood
that exceedances would have been observed on the other five days. In
such cases, if the site does not meet the criteria in section 3.1(f) of
Appendix K that qualifies it to be exempt from expected exceedance
adjustment, then EPA would view the five unmonitored days as days with
missing data. Under Appendix K, for such cases, EPA takes a protective
approach by assuming that the likelihood of exceedances for those five
out of six days equals the likelihood of exceedances for the one in six
days with actual observations. (See section 3.1(a).)
In the case of the East 14th Street site, the continuous instrument
provides extensive data with potential to help EPA evaluate the
likelihood that the high volume sampler would have recorded exceedances
on the five out of six days it was not sampling. EPA therefore examined
whether the continuous instrument data would reliably indicate whether
the high volume sampler would have recorded an exceedance.
EPA compared 24-hour averages from the two instruments for days in
1998 to 2000 when both instruments had valid data. Then EPA developed
what is known as a ``best fit'' equation, which attempts to describe,
as accurately as possible, the relationship between same-day readings
of the two instruments. On average, the high volume sampler reading
equaled 1.05 times the continuous instrument reading plus 0.2
micrograms per cubic meter (g/m3), with a variance
(r2) of 0.78. In no case did the high volume sampler record
any value more than 27 g/m3 higher than the
continuous instrument. Thus, from a sampling perspective, readings from
the two instruments would be considered quite similar.
Consequently, EPA concluded that data from the continuous
instrument is reliable for use in assessing expected exceedances for
the high volume sampler. Specifically, given the excellent agreement
between the measurements produced by the two instruments, EPA believes
the days with continuous instrument measurements but no high volume
sampler measurements should be treated as days with valid data
indicating high volume sampler concentrations. That is, consistent with
the provisions of Appendix K, the best assessment of expected
exceedances under these circumstances would be to consider all days
with data from either instrument as days with valid data, and to treat
as days with missing data only those days in which neither the high
volume sampler nor the continuous instrument was operating. For
purposes of this assessment, a day with only continuous
[[Page 77311]]
instrument data is considered by EPA as having a value below the
standard only if the maximum difference in instrument readings added to
the continuous instrument value indicates a high volume sampler value
below the level of the standard.
EPA described its assessment of the 1999 data in its notice of
proposed rulemaking. Briefly, the high volume sampler recorded an
exceedance during the first quarter. This first quarter included 14
days with high volume sampler values and 74 additional days with only
continuous instrument values. Two days had no value from either
instrument and, under Appendix K, should be considered days with
missing data. The 14 days with high volume sampler values included one
day with a measured exceedance and 13 days with values below the
standard. For the 74 additional days with only continuous instrument
values, the highest such value was 75 g/m3. This
continuous instrument value leads to a best estimated peak value for
the high volume sampler of 79 g/m3 (using the best
fit equation), and leads to a worst case peak estimate of 102
g/m3 (applying the maximum difference in instrument
values). Based on the explanation above, the data from all of these 74
days will be treated by EPA as valid data. In total, then, for the high
volume sampler in the first quarter of 1999, one day had an exceedance,
87 days have concentrations that are well below the standard of 150
g/m3, and two days are lacking data. According to
Appendix K, the proposed rulemaking therefore calculated an estimate of
expected exceedances to be 1 +
(2 * 1/88) or 1.02. Since no exceedances were measured at the site in
any other quarter of 1999 or in 1998 or 1997, the total expected
exceedances for 1999 is 1.02, and the three-year average of expected
exceedances is 0.3.
A second unique feature of the situation at the East 14th Street
site is the occurrence of a second exceedance measured by the
instrument sampling once in six days. In ordinary circumstances, i.e.,
in the absence of collocated daily sampling data, EPA assumes that the
first measured exceedance often reflects only about one expected
exceedance, but EPA would generally assume that a second exceedance
measured by a one-in-six day sampler represents multiple expected
exceedances. However, EPA does not need to rely on such assumptions at
the East 14th Street site, since in this case EPA has a wealth of
actual data with which to assess the likelihood of exceedances at the
site.
EPA therefore estimated expected exceedances for 2000 according to
the same method it used to evaluate the 1999 data. An exceedance was
observed by the high volume sampler in the first quarter of 2000. The
high volume sampler provided values for 15 of the 91 days. The
continuous sampler provided valid data for an additional 73 days. The
highest 24-hour average for these 73 days was 84 g/
m3, suggesting a best estimated peak high volume sampler
value of 88 g/m3 and a worst case estimated high
volume sampler value of 111 g/m3. Three days have
missing values. These data indicate that only 1 out of 88 days with
valid data had an exceedance. Consequently, expected exceedances for
the quarter are estimated at 1 + (3 * \1/88\) or 1.03. The second
quarter had no observed exceedances. Thus, the available data for 2000
at this site indicate 1.03 expected exceedances.
Appendix K does not provide for us to include a half year's worth
of data results in calculating the three year average of expected
exceedances. Thus, consideration of data for the first half of 2000 by
necessity involves projecting likely air quality in the second half of
2000. EPA examined data at the East 14th Street site to judge the most
plausible such projection. In the past, the East 14th Street site has
not been prone to observe exceedances in the second half of the year.
In the 7\1/2\ year history at this site, all three days with recorded
exceedances have been in March. Therefore, EPA has good reason to
anticipate that no further exceedances will be measured at this site in
2000. Assuming no further exceedances for the remainder of 2000 is
equivalent to using data from a previous July to December period, for
example constructing an assessment for 1998 to 2000 by using data from
the second half of 1997 as a surrogate for projected data for the
second half of 2000. This suggests a total of 1.03 expected exceedances
for 2000. This result, in combination with the 1.02 expected
exceedances for 1999 and zero expected exceedances for 1998, indicates
a 3-year average of 0.7 expected exceedances.
The above presents EPA's evaluation of the frequency with which the
high volume sampler at the East 14th Street site would have recorded
exceedances had it been operating every day. One may do a similar
evaluation for the continuous instrument at this site. This continuous
instrument recorded no exceedances from the day it began operating in
April 1998 to the present. This instrument was not operating on March
31, 1999, when the high volume sampler recorded an exceedance, but the
high volume sampler data for that date suggest treating that day as a
day the continuous instrument would be expected to have had an
exceedance. Considering missing data according to Appendix K, this
suggests 1.02 expected exceedances for the first quarter of 1999. While
data are not available for a proper 3-year average of expected
exceedances, the data that are available clearly suggest an average of
less than 1.0 expected exceedances for this instrument. Thus, both
instruments at the East 14th Street site indicate that this site is
attaining the standard.
The commenter provided no rationale for using the computer-
generated statistic he cited rather than applying the judgments and
procedures described in the notice of proposed rulemaking, even though
the two methods clearly give different results. For reasons given here
and in the notice of proposed rulemaking, EPA believes that the
evaluation described here is more consistent with applicable PM
10 regulations and reflects more reasoned judgments about
the air quality at the site in question. EPA is determining on the
basis of this evaluation that this site, like the remainder of Cuyahoga
County, is attaining the standard.
2. Fully Approved SIP
Comment: The second prerequisite for redesignation to attainment is
that EPA has fully approved the applicable SIP for the area. The
commenter states that this prerequisite has not been met because EPA
has not fully approved either the state's new source review (NSR)
programs or the motor vehicle emission budget for these areas. With
respect to NSR, the commenter states that this program is ``not an
optional program that the state and EPA can simply waive based on
claims that it is not `needed' for attainment.'' With respect to
conformity, the commenter cites Section 176(c) of the Clean Air Act and
states that the absence of a motor vehicle emissions budget and
conformity procedures means that EPA has not met all SIP requirements
applicable to the area.
Response: EPA continues to believe that it has fully approved the
applicable SIP for Cuyahoga and Jefferson Counties. For the
requirements added in the Clean Air Act Amendments of 1990, in Subpart
4 of Part D of the Clean Air Act, EPA approved Ohio's attainment
demonstration and other related plan elements on June 12, 1996, at 61
FR 29662. EPA has published several earlier rulemakings approving
Ohio's SIP as meeting the various requirements enacted earlier.
[[Page 77312]]
With respect to NSR, EPA believes that Cuyahoga and Jefferson
Counties may be redesignated to attainment notwithstanding the lack of
a fully-approved NSR program meeting the requirements of the 1990 Clean
Air Act Amendments. This view has been set forth by EPA in a memorandum
from Mary Nichols, Assistant Administrator for Air and Radiation, dated
October 14, 1994, entitled ``Part D New Source Review (part D NSR)
Requirements for Areas Requesting Redesignation to Attainment.'' Also,
see Cincinnati-Hamilton redesignation (65 FR 37879, June 19, 2000) and
Grand Rapids, Michigan redesignation (61 FR 31834-31837, June 21,
1996). This policy has also been applied in ozone redesignations of
Youngstown-Warren, Columbus, Canton, Cleveland-Akron-Lorain, Dayton-
Springfield, Toledo, Preble County, Columbiana County, and Clinton
County, Ohio, as well as Detroit, Michigan.
EPA believes that its decision not to insist on a fully approved
NSR program as a prerequisite to redesignation is justifiable as an
exercise of the Agency's general authority to establish de minimis
exceptions to statutory requirements. See Alabama Power Co. v. Costle,
636 F.2d 323, 360-61 (D.C. Cir. 1979). Under Alabama Power Co. v.
Costle, EPA has the authority to establish de minimis exceptions to
statutory requirements where the application of the statutory
requirements would be of trivial or no value environmentally. In this
context, the issue presented is whether EPA has the authority to
establish an exception to the requirements of section 107(d)(3)(E) that
EPA must fully approve a SIP meeting all of the requirements applicable
to an area under section 110 and part D of title I of the Clean Air Act
before redesignating the area. Plainly, the NSR provisions of section
110 and part D are requirements that were applicable to Cuyahoga and
Jefferson Counties at the time of the submission of the request for
redesignation. Thus, on its face, section 107(d)(3)(E) would seem to
require that the State submit and EPA fully approve a part D NSR
program meeting the requirements of the Clean Air Act before an area
could be redesignated to attainment. Under EPA's de minimis authority,
however, the agency may establish an exception to an otherwise plain
statutory requirement if its fulfillment would be of little or no
environmental value. Therefore, it is necessary to determine what would
be achieved by insisting that there be a fully-approved part D NSR
program in place prior to the redesignation of Cuyahoga and Jefferson
Counties.
EPA believes that requiring the adoption and full approval of a
part D NSR program prior to redesignation would not be of significant
environmental value in this case. When an area is redesignated to
attainment, a new source must satisfy prevention of significant
deterioration (PSD) requirements rather than nonattainment new source
review. PSD requires that new sources demonstrate that their
construction will not increase ambient concentrations significantly and
will not result in concentrations above the air quality standard. This
may be compared to requirements under nonattainment area new source
review for new sources to secure emission reductions to offset their
new emissions. EPA believes that there would be trivial if any
environmental value of applying nonattainment new source requirements
in Cuyahoga and Jefferson Counties rather than PSD requirements.
The other purpose that requiring the full approval of a part D NSR
program might serve is to ensure that NSR would become a contingency
provision in the maintenance plan required for these areas by section
107(d)(3)(E)(iv) and 175A(d). These provisions require that for an area
to be redesignated to attainment, it must receive full approval of a
maintenance plan containing ``such contingency provisions as the
Administrator deems necessary to assure that the State will promptly
correct any violation of the standard which occurs after the
redesignation of the area as an attainment area. Such provisions shall
include a requirement that the State will implement all measures with
respect to the control of the air pollutant concerned which were
contained in the SIP for the area before redesignation of the area as
an attainment area.'' Based on this language, it is apparent that
whether an approved NSR program must be included as a contingency
provision depends on whether it is a ``measure'' for the control of the
pertinent air pollutants.
The term ``measure'' is not defined in section 175A(d) and Congress
utilized that term differently in different provisions of the Clean Air
Act with respect to the PSD and NSR permitting programs. For example,
in section 110(a)(2)(A), Congress requires that SIPs include
``enforceable emission limitations and other control measures, means,
or techniques * * * as may be necessary or appropriate to meet the
applicable requirements of the Act.'' In section 110(a)(2)(C), Congress
requires that SIPs include ``a program to provide for the enforcement
of the measures described in subparagraph (A), and regulation of the
modification and construction of any stationary source within the areas
covered by the plan as necessary to assure that NAAQS are achieved,
including a permit program as required in parts C and D.'' If the term
``measures'' as used in section 110 (a)(2)(A) and (C) had been intended
to include PSD and NSR there would have been no point to requiring that
SIPs include both measures and preconstruction review under parts C and
D (PSD or NSR). Unless ``measures'' referred to something other than
preconstruction review under parts C and D, the reference to
preconstruction review programs in section 110(a)(2)(C) would be
rendered mere surplusage. Thus, in section 110(a)(2) (A) and (C), it is
apparent that Congress distinguished ``measures'' from preconstruction
review. On the other hand, in other provisions of the Clean Air Act,
such as section 161, Congress appeared to include PSD within the scope
of the term ``measures.''
EPA believes that the fact that Congress used the undefined term
``measure'' differently in different sections of the Clean Air Act is
germane. This indicates that the term is susceptible to more than one
interpretation and that EPA has the discretion to interpret it in a
reasonable manner in the context of section 175A. Inasmuch as Congress
itself has used the term in a manner that excluded PSD and NSR from its
scope, EPA believes it is reasonable to interpret ``measure,'' as used
in section 175A(d), not to include NSR. That this is a reasonable
interpretation is further supported by the fact that PSD, a program
that is the corollary of part D NSR for attainment areas, goes into
effect in lieu of part D NSR when an area is redesignated to
attainment. This distinguishes NSR from other required programs under
the Clean Air Act, such as inspection and maintenance programs, which
have no corollary for attainment areas. Moreover, EPA believes that
those other required programs are clearly within the scope of the term
``measure.''
EPA is not suggesting that NSR and PSD are equivalent, but merely
that they are the same type of program. The PSD program is a
requirement in attainment areas and is designed to allow new source
permitting, yet contains adequate provisions to protect the NAAQS. If
any information, including preconstruction monitoring, indicates that
an area is not continuing to meet the NAAQS after redesignation to
attainment, the requirements of 40 CFR part 51, appendix S
(Interpretive Offset Rule) or
[[Page 77313]]
a 40 CFR 51.165(b) program would apply.
With respect to conformity, the requirements cited by the commenter
do not apply to PM10 in these areas. As stated in EPA's
conformity regulations, at 40 CFR 93.102(b), the conformity
requirements apply in ``nonattainment and maintenance areas for
transportation-related criteria pollutants'' [emphasis added}. Within
that section of the conformity regulations, 40 CFR 93.102(b)(2)(iii)
specifies that conformity requirements apply ``in PM10 areas
[only] if the EPA Regional Administrator or the director of the State
air agency has made a finding that transportation-related precursor
emissions within the nonattainment area are a significant contributor
to the PM10 nonattainment problem and has so notified the
MPO and DOT, or if the applicable implementation plan (or
implementation plan submission established a budget for such emissions
as part of the reasonable further progress, attainment or maintenance
strategy.''
Transportation-related emissions do not contribute significantly to
PM10 concentrations in Cuyahoga and Jefferson Counties.
Stationary sources are the predominant contributors to high
concentrations in these areas. The attainment demonstration that EPA
approved for these areas on June 12, 1996, at 61 FR 29662, documents
this finding, and documents that mobile sources contribute only a few
micrograms per cubic meter to airborne concentrations, i.e. only a few
percent of the air quality standards. EPA and the Ohio Environmental
Protection Agency agreed during the 1994 conformity consultation
process that transportation sources are insignificant contributors to
the nonattainment problem in Cuyahoga County and the Steubenville area.
As appropriate, the SIP does not establish a budget for these
emissions. EPA approved conformity rules for Ohio on May 16, 1996 (61
FR 24702) and May 30, 2000 (65 FR 34395). In accordance with applicable
EPA regulations, conformity requirements under the state's rules do not
apply to PM10 in Cuyahoga or Jefferson Counties. Rules
establishing such requirements and approval of an emissions budget are
not prerequisites for full SIP approval or redesignation.
Furthermore, EPA believes it is reasonable to interpret the
conformity requirements as not applying for purposes of evaluating a
redesignation request under section 107(d). The rationale for this
interpretation has been set forth in a number of notices redesignating
areas to attainment for ozone. See, for example, the Cincinnati-
Hamilton redesignation at 65 FR 37879 (June 19, 2000), the Grand Rapids
redesignation at 61 FR 31835-31836 (June 21, 1996), and the Cleveland-
Akron-Lorain redesignation at 61 FR 20458 (May 7, 1996).
3. Permanent and Enforceable Reductions
Comment: The commenter believes that Section 107(d)(3)(E)(iii)
requires that EPA or the State conduct modeling to demonstrate that air
quality improvements are attributable to permanent and enforceable
emission reductions rather than weather patterns, reduction in
production, or other factors.
Response: When Ohio developed its attainment plan, it began by
modeling existing emissions, to identify where existing air quality was
problematic. This modeling identified problems consistent with the
nonattainment problems identified at that time by monitoring. Ohio then
conducted numerous model runs to assess alternative control strategies.
The final modeling analysis demonstrated that the permanent and
enforceable emission reductions which were added as requirements in the
attainment plan regulations were sufficient to bring PM10
concentrations down to attainment levels. Since this modeling reflected
emissions at allowable levels assuming full capacity plant operations,
attainment is not dependent on reduced production or other transient
factors. While EPA does not concede that modeling must be done to
demonstrate that air quality improvements are due to permanent and
enforceable reductions, in this case the type of modeling requested by
the commenter was in fact done. This modeling demonstrated that the air
quality improvement is due to permanent and enforceable reductions.
4. Maintenance
Due to the length and variety of comments on Ohio's maintenance
plan, these comments are addressed in three parts.
Comment: The commenter states that Ohio has failed to submit a SIP
revision that provides for maintenance. The commenter observes that
Ohio ``has merely submitted a letter asserting that the standard will
be maintained. There is no SIP revision comprising the maintenance
plan, and no commitment to implement or continue control strategies
necessary for maintenance.'' The commenter further believes that
``neither the state nor EPA has demonstrated that the standard will in
fact be maintained for [the necessary] ten years''.
The commenter acknowledges that ``EPA presumes'' that declining
population, cleaner new vehicles, and recent regulations on coke oven
emissions will maintain the standards by keeping emissions at or below
levels found in the SIP to assure attainment. However, the commenter
states that Cuyahoga County ``violated the [air quality standards] in
1995, again in 1999, and again in 2000,'' demonstrating that ``holding
emissions to those assumed in the attainment plan most certainly does
not assure attainment.'' The commenter believes that the above
``indicators'' have not been shown to be good indicators of regional
emissions, and observes that ``other factors--e.g., increased
production, construction of new pollution sources, increased per capita
vehicle ownership--[may] cause emissions to rise.'' The commenter cites
EPA rules as requiring modeling to demonstrate maintenance, ``rather
than the intuitive approach proposed here,'' and states that without
``such a modeling demonstration, [EPA] cannot approve maintenance
demonstrations for these areas.''
Response: A maintenance plan must provide sufficient assurances
that attainment of the air quality standard will continue for at least
10 years after the area is redesignated to attainment. A maintenance
plan is not required to add to the set of enforceable emission
limitations in the SIP. If the State can show that the air quality
standard will be maintained without any additional measures beyond
those that are already part of the SIP, then the maintenance plan need
not add any additional measures. Also, if the maintenance plan relies
in part on a previously submitted attainment demonstration, then the
State need not resubmit that attainment demonstration.
Ohio's maintenance plan is in fact based on its previously
submitted attainment demonstration, which EPA approved on June 12,
1996, at 61 FR 29662. This analysis assesses the sum of the impacts of
significant industrial sources at their maximum allowable emissions
plus other, background sources at actual emission levels. Ohio
demonstrated that the sum of these impacts is concentrations below the
standard.
Emissions from the significant sources will be maintained at or
below maximum allowable levels. Therefore, Ohio can demonstrate
maintenance simply by demonstrating that background impacts will remain
at or below current levels.
[[Page 77314]]
Maintenance planning for PM10 differs from maintenance
planning for ozone in this respect. Attainment plans for
PM10 for areas like Cuyahoga and Jefferson Counties must
demonstrate that attainment will occur even if sources emit their
maximum allowable amount. As a result, attainment and maintenance do
not depend on maintaining preexisting levels of production by
facilities in the area. Since the modeled industrial sources in the
area are the principal contributors to high PM10 levels in
these counties, the maintenance plan will consist principally of the
limits on these industrial sources provided in the attainment plan. The
only remaining question pertains to future background concentrations.
If the State can demonstrate that background concentrations will
decline over the next ten years, then the maintenance demonstration
will consist of that demonstration in conjunction with the previously
approved attainment demonstration, and the maintenance plan's control
measures will consist of the control measures in the attainment plan.
Ozone maintenance plans are different because ozone attainment
plans address actual production levels. This means first that ozone
maintenance plans must project any increases or decreases in future
production. Such projections must consider all significant source
types, and cannot be restricted to addressing background contributors.
Thus, maintenance plans for PM10 for areas like Cuyahoga and
Jefferson County are considerably less complicated and have much less
potential to require additional controls than maintenance plans for
ozone.
The commenter expressed concern that the ``indicators'' that Ohio
cites are not indicative of regional PM10 emissions. In
fact, Ohio should not be seeking to indicate trends in regional
emissions. Ohio is properly relying on existing SIP limits to address
the most significant regional emissions, and focusing its additional
trend analyses on sources affecting ``background'' concentrations. Ohio
need not address increased production at important industrial
facilities, because all increases up to maximum production are already
accommodated in the attainment/maintenance demonstration. Ohio need not
address construction of new pollution sources, because PSD regulations
require any significant new source to demonstrate that its emissions
will not cause violations of the standards. Ohio needs to address
increased vehicle ownership, but only as part of an assessment of
trends in background concentrations.
Despite the relative insignificance of motor vehicle emissions, EPA
has examined detailed assessments pertinent to motor vehicle emissions
in Cuyahoga County. Ohio submitted extensive detail on current and
projected traffic volumes in the Cleveland area as part of its
maintenance plan for this area for ozone. Between 1996 and 2010,
traffic volumes are projected to increase by less than one percent per
year. Most of this growth is occurring in the outer counties of the
area; Cuyahoga County traffic is projected to grow by less than \1/3\
percent per year. Meanwhile, emissions per vehicle are declining as a
result of previous regulations plus the tighter fuel and emission
standards of the Tier 2 rules discussed below. Between now and 2010,
emissions per vehicle are expected to decline an average of 2.5 percent
per year, not including the significant emission reductions that will
result from the Tier 2 rules. The net projected effect is a significant
decline in motor vehicle emissions in Cuyahoga County over the next ten
years. Similar information indicates a less than one percent traffic
growth rate in the Steubenville area as well, so this area too will
likely witness declining motor vehicle emissions.
EPA believes that Ohio has addressed important elements of the
background concentrations. EPA believes that the net reduction in motor
vehicle emissions plus the reduction in other emissions associated with
population will yield a net decline in background concentrations.
According to the attainment demonstration that EPA has approved, these
background concentrations in combination with maximum allowable impacts
from significant sources add up to concentrations below the standard.
Consequently, EPA believes that Ohio's maintenance plan provides for
maintenance of the PM10 standards.
Ohio does not explicitly address whether maintenance is assured for
10 years. However, Ohio's approved attainment demonstration shows that
the standard will be maintained, principally due to permanent emission
limits on significant sources, so long as background emissions remain
at or below current levels. Ohio provided evidence that background
emissions will remain at or below current levels throughout the next 10
years. Consequently, EPA is satisfied that Ohio has assured maintenance
for the requisite 10 years.
Comment: The commenter cites results of an EPA analysis conducted
in conjunction with adoption of Tier 2 motor vehicle emission
standards, discussed in the Federal Register of February 10, 2000 (65
FR 6698 and 6719). The commenter states that ``EPA identified Cuyahoga
County as an area with a 'significant risk of failing to attain and
maintain the PM10 [air quality standards] without further reductions in
emissions.''' The commenter acknowledges future reductions from the
Tier 2 standards but states that ``EPA has not shown that these
reductions will be sufficient or will occur soon enough to prevent
NAAQS violations'' throughout the next 10 years.
Response: In preparation for adopting its Tier 2 motor vehicle
emission standards, EPA attempted a national analysis of prospective
attainment with and without these standards. EPA identified eight areas
as areas of ``high risk of failing to attain or maintain the
PM10 NAAQS''. These areas had monitored violations in 1996
to 1998 and were projected to have continued violations in 2030 without
the Tier 2 standards. These areas were all in California or neighboring
States. EPA then identified five additional counties, including
Cuyahoga County, as having a risk of future violations of the
PM10 NAAQS. These counties were defined as attaining the
NAAQS based on 1996 to 1998 data but projected to violate the standards
in 2030 in the absence of Tier 2 regulations. The rulemaking cited by
the commenter states, ``There is a substantial risk that at least some
of [these latter five counties] would fail to maintain without further
emission reductions. The emission reductions from the Tier 2/Gasoline
Sulfur program will help to keep them in 40 attainment.'' EPA in fact
adopted the Tier 2 regulations, so projections of possible future
nonattainment without these regulations are irrelevant. Contrary to the
commenter's statements, EPA's analysis for the relevant scenario (with
Tier 2 standards) shows continued maintenance. In addition, a
projection that vehicle emissions without Tier 2 standards could reach
levels sufficient to help cause violations by 2030 does not necessarily
mean that violations would occur by 2010, the timeframe that is germane
here. In any case, the Tier 2 rulemaking notes that ``[a]fter reviewing
public comments on our presentation of these modeling results, [EPA]
concluded that [its analysis is] suitable for estimating PM
concentration reductions for economic benefits estimation, [but] it is
not a tool we can use with high confidence for predicting that
individual areas that are now in
[[Page 77315]]
attainment will become nonattainment in the future.'' Thus the most
relevant analysis is Ohio's attainment modeling and maintenance plan
information, which considers local data on the significance of motor
vehicle emissions and on the population (and thus the number of
drivers). This information, like the Tier 2 analysis, supports EPA's
conclusion that Cuyahoga County will maintain the PM10 NAAQS
over the next ten years.
Comment: The commenter objects that what EPA calls a maintenance
plan ``lacks enforcement programs and commitments of resources'' as
well as ``legal authority.'' In addition, the commenter states that
PM10 motor vehicle emissions budget is ``required not only
for purposes of the attainment plan, but also for a maintenance plan as
well.'' Finally, the commenter states that ``the state lacks adequate
contingency plans for maintenance'' pursuant to Section 175A(d). The
commenter acknowledges that Ohio has contingency measures ``designed to
produce limited annual progress toward attainment in the event of a
shortfall,'' but the commenter believes that these measures fail to
meet a different requirement applicable to maintenance plans ``to
assure that the State will promptly correct any violation of the
standard.''
Response: The requirements under Section 110(a)(2)(E) that the
commenter cites were addressed in general by Ohio in its initial SIP,
submitted on January 31, 1972, and ultimately approved on April 15,
1974 (39 FR 13539). EPA's conclusion in that rulemaking remains valid,
that Ohio's enforcement program, commitment of resources, and legal
authority are adequate and assure that measures in the SIP (including
maintenance plan measures) will be implemented. See Calcagni Memorandum
cited above and Southwestern Pennsylvania Growth Alliance v. Browner,
144 F.3d 984 (6th Cir. 1998). See also discussion in Cincinnati-
Hamilton redesignation notice at 65 FR 37882. If EPA were to find that
SIP measures were not being implemented, for lack of the above or for
any other reason, the process leading to sanctions under Section
179(a)(4) would commence.
A response above clarifies that motor vehicle emission budgets are
not required for PM10 in areas where motor vehicles do not
contribute significantly to PM10 nonattainment. Thus,
neither the attainment plans nor the maintenance plans for Cuyahoga and
Jefferson Counties need to have a motor vehicle emissions budget.
The commenter acknowledges that the Ohio SIP includes contingency
measures. These measures, approved on May 6, 1996 (61 FR 20142), are
triggered on the basis of air quality monitoring data irrespective of
attainment status. That is, these measures are valid maintenance plan
contingency measures because they take effect if violations recur for
any reason after redesignation of the areas to attainment. The question
of interest here, then, is whether these contingency measures are
adequate to satisfy Section 175A(d).
The commenter's quote from Section 175A(d) omits a key qualifier
that invokes EPA's judgment in assessing contingency measure adequacy
for maintenance plan purposes. The full sentence in Section 175A(d)
reads: ``Each plan revision submitted under this section shall contain
such contingency provisions as the Administrator deems necessary
[emphasis added] to assure that the State will promptly correct any
violation of the standard which occurs after the redesignation of the
area as an attainment area.'' Section 175A(d) does not dictate that the
maintenance plan contingency measures be sufficient by themselves to
correct any violation of the standard. Instead, these measures need
only be sufficient in EPA's judgment to help assure that the State will
promptly correct any future violation.
A variety of sources emit PM10, so nonattainment can
occur for a variety of reasons. EPA cannot reasonably expect
maintenance plan contingency measures by themselves to address all
possible future violations. Instead, EPA must judge the contingency
measures in the context of the types of future violations that it views
as most likely and in the context of other factors which help assure
that the State will correct any future violations.
Additional factors that help assure prompt correction of any future
PM10 violation in Cuyahoga County or the Steubenville area
include provisions in Ohio's regulations that allow the State to impose
additional source controls if violations occur and provisions in the
Clean Air Act Section 110(h) (provisions for SIP Calls). EPA is
satisfied that the contingency measures that are included in Ohio's
maintenance plan for Cuyahoga and Jefferson Counties, in combination
with other factors, assure that Ohio will promptly correct any future
violations in these areas.
III. What Actions Is EPA Taking, and Why?
EPA is redesignating Cuyahoga and Jefferson Counties in Ohio to
attainment for PM10 and is approving Ohio's PM10
maintenance plan for these counties. The redesignation action reflects
EPA's judgment of Ohio's request, focusing on the five criteria given
in Clean Air Act Section 107(d)(3)(E) for redesignations from
nonattainment to attainment.
The first criterion is that the areas are in fact attaining the
standards. The standards in question are the PM10 standards
given in 40 CFR 50.6, promulgated in 1987. Although EPA promulgated new
standards for PM10 into 40 CFR 50.7, these new standards
have been vacated by the District of Columbia Circuit Court of Appeals,
no designations have been promulgated for these new standards, and this
rule addresses only the older standards.
No concentrations exceeding the applicable standards have been
recorded in Jefferson County or in most of Cuyahoga County. Exceedances
occurred at two sites in Cleveland. One site was found to have 2
exceedances of the 24-hour standard over 3 years, which was found to
translate to 0.7 expected exceedances per year. EPA proposed this
finding, no commenter challenged this finding, and EPA now concludes
that the standard is being attained at this site. A second site
observed 1 exceedance of the 24-hour standard in 1997 to 1999, which
was found to translate to 0.3 expected exceedances per year. A
commenter challenged this view, noting that EPA's AIRS database
indicates 6 expected exceedances in 1999 as well as 6 expected
exceedances in 2000. As discussed above in response to comments, EPA
finds that the more sophisticated methods of data interpretation
described in the proposed rulemaking give a better assessment of
expected exceedances at this site. These methods indicate that the site
had approximately one expected exceedance for 1999. A similar
assessment of the data so far in 2000 also indicate approximately one
expected exceedance. While it is problematic to average in data for
only half of 2000, these data support a conclusion that expected
exceedances averaged over 3 years is less than 1.0. Consequently, EPA
finds that these two sites, as well as the rest of Cuyahoga County, are
attaining the applicable PM10 standards.
As noted in the proposed rulemaking, Jefferson County is part of a
two-state area that also includes a portion of Brooke County, West
Virginia. Satisfaction of the attainment criterion requires that air
quality throughout this two-state Steubenville area be attaining the
standards. The West Virginia portion of this area has one monitor,
which has shown no recent
[[Page 77316]]
exceedances. Thus, this criterion is met because the entire
Steubenville area is attaining the standards.
The second criterion is that EPA has fully approved the applicable
implementation plan for the areas. The most recent approval, including
approval of Ohio's attainment demonstrations, was published on June 12,
1996, at 61 FR 29662. Other applicable plan elements were approved on
prior occasions. EPA does not require full approval of new source
review rules or conformity as a prerequisite for redesignation, and,
moreover, the conformity regulations do not apply to these areas for
PM10. While approval of the SIP for the West Virginia
portion of the Steubenville area was published separately, both SIPs
have been approved on the basis of the same, jointly developed
attainment strategy.
The third criterion is that the air quality improvement be due to
permanent and enforceable reductions. EPA finds that air quality has
significantly improved as a result of emission reductions that limits
in the SIP make permanent and enforceable.
The fourth criterion is that EPA has fully approved a maintenance
plan. This rule approves Ohio's maintenance plan for Cuyahoga and
Jefferson Counties. Ohio held a public hearing on its maintenance plan
and otherwise satisfied the procedural requirements for adopting and
submitting this plan. The most important part of this plan is the
continuation of SIP emission limits on major industrial sources which
have been shown by modeling to assure attainment even if the sources
operate at maximum capacity. Additional factors will assure that the
remaining, background concentrations will remain at attainment levels,
including ongoing plus forthcoming mobile source control requirements
as well as population declines in the two areas. Although a commenter
expressed numerous concerns about Ohio's maintenance plans, the review
of those concerns discussed in the previous section lead EPA to
conclude that the maintenance plans fully meet applicable requirements.
With today's approval of Ohio's maintenance plans, the fourth criterion
for redesignation of the two counties is satisfied.
The fifth criterion for redesignation is that the State has met all
requirements under Section 110 and Part D of the Clean Air Act that
apply to the areas. This criterion is similar to the second criterion,
and EPA finds that Ohio has met all relevant requirements.
For the Steubenville area, EPA is taking action today only on the
Ohio portion of this area. This approach is for administrative
convenience and in no way signifies any splitting of the area into
separate air quality planning areas. EPA's action today reflects a
review of the air quality for the full Steubenville area as well as
Ohio's fulfillment of its portion of an attainment plan that Ohio and
West Virginia jointly developed. EPA has received no redesignation
request for the West Virginia portion of the Steubenville area. EPA
anticipates receiving and rulemaking on such a request in the near
future. If in the future the standard is violated in either portion of
the area, such that redesignation back to nonattainment is warranted,
EPA will reinstate nonattainment status for the entire area.
IV. Administrative Requirements
A. Executive Order 12866
The Office of Management and Budget (OMB) has exempted this
regulatory action from Executive Order 12866, entitled ``Regulatory
Planning and Review.''
B. 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.
This rule is not subject to Executive Order 13045 because it does
not involve decisions intended to mitigate environmental health or
safety risks that may have disproportionate effects on children.
C. Executive Order 13084
Under Executive Order 13084, EPA may not issue a regulation that is
not required by statute, that significantly affects 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 the Office of Management and Budget,
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 rule does not significantly or uniquely affect the
communities of Indian tribal governments. This action does not involve
or impose any requirements that affect Indian Tribes. Accordingly, the
requirements of section 3(b) of Executive Order 13084 do not apply to
this rule.
D. Executive Order 13132
Federalism (64 FR 43255, August 10, 1999) revokes and replaces
Executive Orders 12612 (Federalism) and 12875 (Enhancing the
Intergovernmental Partnership). Executive Order 13132 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 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. 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.
This rule will not have substantial direct effects on the States,
on the relationship between the national government and the States, or
on the
[[Page 77317]]
distribution of power and responsibilities among the various levels of
government, as specified in Executive Order 13132, because it merely
affects the status of a geographical area, does not impose any new
requirements on sources, or allows a state to avoid adopting or
implementing other requirements, and does not alter the relationship or
the distribution of power and responsibilities established in the Clean
Air Act. Thus, the requirements of section 6 of the Executive Order do
not apply to this rule.
E. Executive Order 12898
Executive Order 12898 (59 FR 7629, February 16, 1994) instructs EPA
to address, as appropriate, disproportionately high and adverse health
or environmental effects on minority and low-income populations. EPA
has found that this rulemaking is consistent with Executive Order 12898
and does not impose any disproportionately high and adverse human
health or environmental effects on minority and low-income populations.
F. Regulatory Flexibility
The Regulatory Flexibility Act (RFA) generally requires an agency
to conduct a regulatory flexibility analysis of any rule subject to
notice and comment rulemaking requirements unless the agency certifies
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 small governmental
jurisdictions.
This rule will not have a significant impact on a substantial
number of small entities because SIP approvals under section 110 and
subchapter I, part D of the Clean Air Act do not create any new
requirements but simply approve requirements that the State is already
imposing. In addition, redesignation of an area to attainment under
section 107(d)(3)(E) of the Clean Air Act does not impose any new
requirements on small entities. Redesignation is an action that affects
the status of a geographical area and does not impose any new
requlatory requirements on sources. Therefore, because the Federal SIP
approval does not create any new requirements, I certify that this
action will not have a significant economic impact on a substantial
number of small entities. Moreover, due to the nature of the Federal-
State relationship under the Clean Air Act, preparation of flexibility
analysis would constitute Federal inquiry into the economic
reasonableness of state action. The Clean Air Act forbids EPA to base
its actions concerning SIPs on such grounds. Union Electric Co. v. U.S.
EPA, 427 U.S. 246, 255-66 (1976); 42 U.S.C. 7410(a)(2).
G. Unfunded Mandates
Under sections 202 of the Unfunded Mandates Reform Act of 1995
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA
must prepare a budgetary impact statement to accompany any proposed or
final rule that includes a Federal mandate that may result in estimated
costs to State, local, or tribal governments in the aggregate; or to
the private sector, of $100 million or more. Under section 205, EPA
must select the most cost-effective and least burdensome alternative
that achieves the objectives of the rule and is consistent with
statutory requirements. Section 203 requires EPA to establish a plan
for informing and advising any small governments that may be
significantly or uniquely impacted by the rule.
EPA has determined that the approval action promulgated does not
include a Federal mandate that may result in estimated costs of $100
million or more to either State, local, or tribal governments in the
aggregate, or to the private sector. This Federal action approves pre-
existing requirements under State or local law, and imposes no new
requirements. Accordingly, no additional costs to State, local, or
tribal governments, or to the private sector, result from this action.
H. Submission to Congress and the Comptroller General
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). This rule will be effective January 10, 2001.
I. 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 a new regulation. To comply with
NTTAA, 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.
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, and 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. Redesignation
is an action that affects the status of a geographical area but does
not impose any new requirements on sources. 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.
J. Petitions for Judicial Review
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 February 9, 2001. 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).)
Nothing in this action should be construed as permitting or
allowing or establishing a precedent for any future request for
revision to any SIP. Each request for revision to any SIP shall be
considered separately in light of specific technical, economic, and
environmental factors and regulatory requirements.
