ACTION: Final rule.
AGENCY:
SUMMARY: EPA is finding that the
Imperial Valley serious PM–10
nonattainment area did not attain the
24-hour particulate matter (PM–10)
National Ambient Air Quality Standard
(NAAQS) by the deadline mandated in
the Clean Air Act (CAA), December 31,
2001. In response to this finding, the
State of California must submit a
revision to the California State
Implementation Plan (SIP) that provides
for attainment of the PM–10 standard in
the Imperial Valley area and at least five
percent annual reductions in PM–10 or
PM–10 precursor emissions until
attainment as required by CAA section
189(d). The State must submit the SIP
revision by December 11, 2008.

I. Background
On August 11, 2004, EPA reclassified
under the Clean Air Act (CAA or the
Act) the Imperial Valley PM–10
nonattainment area (Imperial area) from
moderate to serious in response to the
opinion of the U.S. Court of Appeals for
the Ninth Circuit in Sierra Club v.
United States Environmental Protection
Agency, et al., 346 F.3d 955 (9th Cir.
2003), amended 352 F.3d 1186, cert.
denied, 542 U.S. 919 (2004). See 69 FR
48792 (August 11, 2004).
Also on August 11, 2004 (69 FR
48835), EPA proposed to find under the
CAA that the Imperial area failed to
attain the annual 1 and 24-hour PM–10
standards by the serious area deadline
of December 31, 2001. Our proposed
finding of failure to attain was based on
monitored air quality data for the PM–
10 NAAQS from January 1999 through
December 2001. A summary of these
data was provided in the proposed rule
and is not reproduced here.
EPA has the responsibility, pursuant
to sections 179(c) and 188(b)(2) of the
Act, of determining within 6 months of
the applicable attainment date (i.e., June
30, 2002), whether the Imperial area
attained the PM–10 NAAQS. Because
the June 30, 2002 date has passed, EPA
is required to make that determination
as soon as practicable. Delaney v. EPA,
898 F.2d 687 (9th Cir. 1990).
Section 179(c)(1) of the Act provides
that attainment determinations are to be
based upon an area’s ‘‘air quality as of
1 Effective December 18, 2006, EPA revoked the
annual PM–10 standard. 71 FR 61144 (October 17,
2006). References to the annual standard in this
proposed rule are for historical purposes only. EPA
is not taking any regulatory action with regard to
this former standard.
E:\FR\FM\11DER1.SGM

Federal Register / Vol. 72, No. 237 / Tuesday, December 11, 2007 / Rules and Regulations
the attainment date,’’ and section
188(b)(2), which is specific to PM–10, is
consistent with that requirement. EPA
determines whether an area’s air quality
is meeting the PM–10 NAAQS based
upon air quality data gathered at
monitoring sites in the nonattainment
area and entered into EPA’s Air Quality
System (AQS) database. These data are
reviewed to determine the area’s air
quality status in accordance with EPA
regulations at 40 CFR part 50, appendix
K.2 For details about EPA’s proposed
failure to attain finding, please see the
proposed rule.
II. EPA’s Responses to Comments on the
Proposed Rule
EPA received eight comment letters
on the proposed finding. Summaries of
the comments and EPA’s responses are
set forth below.
1. Retroactive Finding of Failure To
Attain Is Unlawful
The Imperial County Air Pollution
Control District (District or ICAPCD)
claimed that EPA’s proposed finding
that the Imperial area failed to attain the
serious area deadline of December 31,
2001, issued the same day as the
reclassification of the area from
moderate to serious, constitutes an
unlawful and unjust retroactive
rulemaking in that the area would be at
once reclassified and punished for
failing to meet the requirements of the
new classification. The District strongly
urged EPA to refrain from finalizing any
rule that makes a nonattainment finding
under these circumstances.
In support of its position that this
type of rulemaking is illegal under the
Administrative Procedure Act (APA),
the District cited a number of federal
court decisions and EPA rulemakings.
The District believes that these
decisions and rulemakings support its
position that the nonattainment finding
could create liabilities and penalties for
missing long past deadlines associated
with serious nonattainment areas and/or
impose more rigorous requirements than
would otherwise be justified, e.g., the
requirement under CAA section 189(d)
to submit a revised plan in 12 months
rather than the 18 months allowed
under section 189(b)(2) when a
rfrederick on PROD1PC67 with RULES
2 Pursuant
to appendix K, attainment of the 24hour PM–10 NAAQS is achieved when the
expected number of exceedances of the 24-hour
NAAQS (150 mg/m3) per year at each monitoring
site is less than or equal to one. A total of three
consecutive years of clean air quality data is
generally necessary to show attainment of the 24hour standard for PM–10. A complete year of air
quality data, as referred to in 40 CFR part 50,
appendix K, is comprised of all four calendar
quarters with each quarter containing data from at
least 75 percent of the scheduled sampling days.

moderate area fails to meet its
attainment deadline.
Response: At bottom, the argument
that the District makes is that if the
Imperial area had been reclassified as
the CAA envisioned, the area would not
now be subject to the requirements of
section 189(d). In other words, EPA
would have found that the area failed to
attain the moderate area deadline of
December 31, 1994 well before the
serious area deadline of December 31,
2001. Consequently, the serious area
plan for the Imperial area would have
been due 18 months from the
reclassification pursuant to section
189(b)(2) instead of being subject to the
12-month deadline in section 189(d).
Furthermore, the argument goes, if the
State had been able to demonstrate that
attainment by 2001 was impracticable
the area would have been able to avail
itself of the attainment date extension
provisions of section 188(e),3 thereby
potentially avoiding both the
substantive and procedural
requirements of section 189(d) entirely.
Instead, the District argues, EPA’s action
has illegally circumvented the statutory
scheme by precluding the area from
taking advantage of allegedly more
lenient submittal and substantive
requirements.
The cases and EPA actions cited by
the District, however, do not support its
position. With respect to the Imperial
PM–10 nonattainment area, EPA
reclassified it from moderate to serious
and immediately proposed to find that
the area had failed to attain the serious
area deadline. The result of these
actions is that the State will be required
to submit in the future a plan for the
area under CAA section 189(d). In
contrast, in Sierra Club v. EPA, 356 F.3d
296 (D.C. Cir. 2004), EPA set a
prospective submittal date pursuant to
CAA section 182(i) upon reclassification
of the Washington, D.C. ozone
nonattainment area from serious to
severe because the severe area plan
submittal deadline in the CAA had
already passed. Similarly, in several
other ozone reclassification actions,
EPA also determined that where a
submittal date had passed and was
3 Section 188(e) provides for a one-time extension
of the attainment deadline for serious PM–10
nonattainment areas if certain conditions are met.
However such an extension cannot extend beyond
December 31, 2006. Because that date has now
passed, a section 188(e) extension for the Imperial
area is unavailable under any circumstances.
Nevertheless we address in this final rule the
comments we received relating to section 188(e)
insofar as doing so enables us to fully respond to
those comments. For example, here a discussion of
section 188(e) is relevant to the District’s claim,
among others, that EPA’s action subjects the area to
more stringent requirements than otherwise would
have been imposed.

therefore impossible to meet, the
Agency could administratively establish
a later date. EPA’s reasoning in these
cases was that to do otherwise would
have subjected these areas to an
immediate finding of failure to submit
and the immediate initiation of
sanctions clocks.4
In the case of Washington, DC, EPA
stated in its final rule that ‘‘the
Administrative Procedure Act * * *
requires that before a rule takes effect,
persons affected will have advance
notification of its requirements. A
failure to meet an obligation, especially
one accompanied by sanctions, cannot
occur in advance of the imposition of
that obligation.’’ 68 FR at 3414. The
Court of Appeals agreed, quoting EPA,
‘‘that adopting petitioner’s suggestion
[that EPA retain the original submittal
deadlines] ‘would give the
reclassification retroactive effect by
holding the States in default of their
submission obligations before the events
necessary to trigger that obligation
(reclassification) * * * occurred.’ ’’ 356
F.3d at 309.
In Sierra Club v. Whitman, 130
F.Supp. 2d. 78 (D.D.C. 2001), cited by
the D.C. Circuit in Sierra Club v. EPA
above and the District in its comment
letter, and affirmed in Sierra Club v.
Whitman, 285 F.3d 63, 68 (D.C. Cir
2002), the plaintiffs sought to compel
EPA to backdate a nonattainment
determination to the date on which the
Agency was statutorily required to make
such a determination. In affirming the
District Court’s denial of the relief
sought, the D.C. Circuit opined that:
Although EPA failed to make the
nonattainment determination within the
statutory time frame, Sierra Club’s proposed
solution only makes the matter worse.
Retroactive relief would likely impose large
costs on the States, which would face fines
and suits for not implementing air pollution
prevention plans in 1997, even though they
were not on notice at the time.
Id. at 68.5
In the instant case, however, by giving
the State the benefit of a future plan
submittal deadline for the Imperial area,
EPA’s action is consistent with the
holdings of the cases and with the EPA
regulatory actions cited by the District.

24, 2003). See also Santa Barbara, California, 62 FR

FR 60001 (November 6, 1997); and Dallas-Fort
Worth, Texas, 63 FR 8128 (February 18, 1998).
5 The District also cites Georgetown University
Hospital v. Bowen in which a federal agency
reissued a procedurally defective rule and gave it
retroactive effect. Both the D.C. Circuit and the U.S.
Supreme Court invalidated the action, finding,
among other things, that under the APA legislative
rules must be given future effect only. 821 F.2d 759
(D.C. Cir. 1987); 488 U.S. 204 (1988).

70224
Federal Register / Vol. 72, No. 237 / Tuesday, December 11, 2007 / Rules and Regulations
Under section 189(d), the State must
submit a plan revision for the Imperial
area ‘‘within 12 months after the
applicable attainment date. * * *’’ That
date was December 31, 2002. However,
because, at the time of EPA’s proposed
finding of failure to attain, that date had
already passed, EPA proposed that the
section 189(d) plan revision be due
‘‘within one year of publication of a
final finding of nonattainment pursuant
to CAA section 179(d).’’ 69 FR at 48837.
Thus, rather than invoking the long past
submittal deadline in section 189(d),
EPA looked to another provision of the
Act to supply a prospective deadline. In
doing so, EPA alleviated the problem of
imposing a retroactive deadline without
imposing immediate sanctions.
While it is true, as the District points
out, that a serious PM–10 area
proceeding initially under section
189(b) instead of section 189(d) would
in theory have had more time to submit
a plan (18 rather than 12 months), in
both instances the submittal deadlines
are prospective and not retroactive.
Furthermore, as we point out in our
response to comment #3 below, the
section 189(d) plan that the State is now
required to submit is actually due later
than the serious area plan would have
been due under the scenario preferred
by the District. Therefore, the retroactive
penalty the District complains of with
respect to the plan submittal deadline
simply does not exist.
Moreover, while it is also true that, as
a result of EPA’s nonattainment finding,
the Imperial area must comply with the
substantive requirements of CAA
section 189(d) instead of those of
section 188(e), this consequence cannot
be construed as ‘‘punishment.’’ Under
both sections 189(d) and 188(e),
implementation of best available control
measures (BACM) under section
189(b)(1) and attainment of the PM–10
standards as expeditiously as
practicable are required. In addition,
while the respective substantive
requirements of sections 188(e) and
189(d) are different, neither are
necessarily more onerous than the other.
See Corrected Brief of Respondent EPA,
pages 40–42, in Association of Irritated
Residents, et al. v. EPA, 423 F.3d 989
(9th Cir. 2005). Only if the State fails to
submit the new plan in the future could
sanctions come into play. Thus the
substantive consequences here of EPA’s
nonattainment finding are not in fact
retroactive, nor do they impose a
penalty.
For the reasons discussed in its
proposed finding, EPA is legally
compelled to finalize the nonattainment
finding with the result that section
189(d) applies to the Imperial area. The
VerDate Aug<31>2005

section 189(d) plan is due within one
year of publication of this final finding
of nonattainment.6
2. Waive the Attainment Date and
Related Requirements
Several commenters suggested that
instead of finding that the Imperial area
failed to attain the serious area
attainment date, EPA should waive that
date and the related submittal
requirements and penalties to reduce
the burden of the Agency’s action on
Imperial County. While two
commenters who suggested this
approach did not describe EPA’s legal
authority to grant a waiver, one
commenter, the District, cited CAA
section 188(f) as providing EPA with the
authority to waive a specific attainment
date where the Agency determines that
nonanthropogenic sources contribute
significantly to violations in the area
and to waive any requirement
applicable to any serious PM–10 area
where anthropogenic sources do not
contribute significantly to violations.
The District stated that in the Imperial
area, dry soil from vast barren lands are
entrained by high winds producing an
impact on the monitors. The District
asserted that EPA has determined that
this type of dust raised by high wind
events constitutes a nonanthropogenic
source of PM–10 pursuant to section
188(f) and, citing a May 30, 1996 EPA
memorandum, that monitoring data
impacted by such events may be
excluded from consideration in
attainment decisions.
Response: Congress recognized in the
Clean Air Act that there may be areas
where the NAAQS may never be
attained because of PM–10 emissions
from nonanthropogenic sources, and
that the imposition in such areas of
certain state planning requirements may
not be justified. Therefore, under
section 188(f), Congress provided a
means for EPA to waive a specific date
for attainment and certain control and
planning requirements when specified
conditions are met in a nonattainment
area. Section 188(f) provides two types
of waivers. First, EPA may, on a caseby-case basis, waive any PM–10
nonattainment planning requirement
applicable to any serious nonattainment
area where EPA determines that
anthropogenic sources of PM–10 do not
contribute significantly to violation of
the standards in the area. Second, EPA
may waive a specific date for attainment
of the standards where EPA determines
that nonanthropogenic sources of PM–

10 contribute significantly to the
violation of the standards in the area.7
In the Addendum, EPA set forth
threshold levels for determining
whether areas qualify for waivers under
section 188(f). Addendum at 42004–
42005.
In its comment letter, the District
included and discussed a report 8 that it
characterized as showing that
windblown dust from barren lands
represents over 92% or 792 tons per day
(tpd) of the total PM–10 inventory in
Imperial County. The District
maintained that ‘‘high winds frequently
entrain large amounts of this dry soil
into the ambient air, producing a
documented impact on County
monitors.’’ As a result of comments
provided to the District by EPA and the
California Air Resources Board (CARB),
the Windblown Dust Study was revised
in 2005.9 The Revised Study concluded,
among other things, that there are 157
tpd of fugitive dust emissions from
barren lands. Revised Study at A–15.
The Windblown Dust Study and the
Revised Study are primarily inventories
of windblown dust emissions in
Imperial County. These documents do
not address the requirements of section
188(f) and EPA’s guidance on that
provision. Therefore they do not
provide sufficient analysis and
documentation to support a waiver of
either the December 31, 2001 attainment
deadline or any of the serious area
requirements. However, the section
188(f) waivers, if the conditions for
them can be met, are available to the
State in the context of the section 189(d)
serious area plan.10

by the District is entitled ‘‘Areas
Affected by PM–10 Natural Events’’ and

10 With respect to the section 188(f) waiver of
serious area requirements, EPA cautions that while
the District in its comment appears to characterize
the predominant issue in the Imperial area to be
nonanthropogenic sources, the District has
identified anthropogenic PM–10 source categories
that contribute significantly to peak 24-hour average
PM–10 values in the area. See Regulation VIII

rfrederick on PROD1PC67 with RULES
is from Mary Nichols, Assistant
Administrator for Air and Radiation to
EPA Regional Division Directors
(Natural Events Policy or NEP). This
policy provides, among other things,
that EPA believes it is appropriate to
exclude air quality data attributable to
uncontrollable natural events from the
Agency’s decisions regarding an area’s
attainment status. NEP at p. 2.11 In the
case of high winds, under the NEP EPA
considers ambient PM–10
concentrations due to dust raised by
unusually high winds as due to
uncontrollable natural events (and thus
excludable from attainment
determinations) if either (1) the dust
originated from nonanthropogenic
sources or (2) the dust originated from
anthropogenic sources controlled with
BACM. NEP at pp. 4–5.
The NEP sets forth a process for
declaring an exceedance as due to
natural events and for documenting a
natural events claim. NEP at pp. 7–10.
Where a state believes that natural
events caused the NAAQS exceedances
it must establish through supporting
documentation a clear causal
relationship between the exceedance
and the natural event. The amount and
type of documentation must be
sufficient to demonstrate that the
natural event occurred and that it
impacted a particular monitoring site in
such a way as to cause the PM–10
concentrations measured. The
documentation also should provide
evidence that, absent the natural event
emissions, concentrations at the
monitoring site would not cause an
exceedance.
Under the NEP, when air quality data
affected by a natural event are submitted
to EPA for inclusion into the AIRS
database,12 the state is to request that a
flag be placed on the data to indicate
that a natural event was involved. NEP
at 8–9. A number of exceedances in
1999–2001 in the Imperial area were
flagged as high wind and other natural
events. Under the NEP, the
documentation supporting a natural
events flag was required to be submitted
no later than 180 days from the time the
11 On March 22, 2007, EPA issued a final rule,
intended to replace the NEP, governing the review
and handling of air quality data influenced by
exceptional events. 72 FR 13560. The rule became
effective on May 21, 2007 and is codified at 40 CFR
50.1, 50.14 and 51.920. 72 FR 13560, 13580–13581.
However, as discussed below, the 1999–2001 data
relevant to this final action are not eligible for
exclusion under the transition policy for the rule
because the State did not meet the provisions of the
NEP that were applicable at the time of the
exceedances. See 72 FR 49046, 49048 (August 27,
2007).

exceedance occurred. However no
documentation with respect to the
1999–2001 exceedances was submitted
to EPA.13 Because the State did not
comply with the provisions of the NEP,
the flagged 1999–2001 data cannot be
excluded as affected by natural events
from EPA’s determination of whether
the Imperial area attained the PM–10
standard by December 31, 2001.

To Allow More Time To Develop Plan
Several commenters opposing our
proposed action stated that our
proposed time frame for the
development and submittal of a serious
area PM–10 plan, including a CAA
section 189(d) plan, was too short, and
that EPA should grant a 5-year
extension of the attainment date for the
Imperial area to provide time for
preparation, submittal and
consideration of an attainment
demonstration. Of the commenters
making this request, only the District
cited any legal authority for a 5-year
extension: ‘‘* * * The District requests
that EPA withdraw its proposed 12month deadline for the County’s serious
area SIP submittal * * * and instead
grant a five-year extension under
Section 188(e) to allow sufficient time
for preparation, submittal and
consideration of the County’s final PM–
10 attainment demonstration.’’ The
District characterized the 12-month plan
submittal schedule as ‘‘abbreviated’’ and
as a ‘‘penalty.’’ One of the commenters
suggesting the 5-year extension
approach urged EPA to utilize our
discretion under the CAA to extend the
time allowed to prepare a plan so that
unwarranted imposition of additional
measures could be avoided.
Another commenter stated that
although a preferable outcome would
have been an extension of the
attainment date, it was clear that no
attainment date extension was in place,
and thus, the finding of failure to attain
by EPA was mandatory under the Clean
Air Act with the one-year deadline for
an attainment demonstration.
Response: CAA section 188(e)
provides that, upon application by a
state, EPA may extend the attainment
deadline for a serious PM–10
nonattainment area no more than 5
years beyond, in this case, December 31,
2001, if: (a) Attainment by that date
would be impracticable; (b) the state has
complied with all requirements and
13 Note that even if adequate documentation had
been submitted for the flagged events, the Imperial
area would not have attained the PM–10 standard
because of the number of unflagged exceedances.

2001,’’ Excel Spreadsheet, Bob Pallarino, EPA.

commitments in the implementation
plan for the area; and (c) the state
demonstrates that the plan contains the
most stringent measures (MSM) in the
plan of any state or are achieved in
practice in any state, and can feasibly be
implemented in the area. The state must
submit at the time of its extension
application a demonstration of
attainment by the most expeditious
alternative date practicable.
As stated above, the Imperial area is
no longer eligible for an attainment date
extension under section 188(e) because
that extension cannot extend beyond
2006. Regardless, the attainment date
extension provided for in section 188(e)
does not relate in any way to the
submittal date for a serious area plan.
Rather, under the Act, submittal dates
for serious area PM–10 plans are
initially governed by subpart 4 of part
D of the CAA, i.e, either by section
189(b)(2) or 189(d). As explained in the
proposed rule, EPA believes that section
189(d) applies to the Imperial area’s
situation. 69 FR at 48837. In the first
instance, EPA looked to this provision,
which applies exclusively to PM–10
nonattainment areas, for the applicable
submittal date for the Imperial area’s
section 189(d) plan. Because the
deadline for plan submittal under that
section, December 31, 2002 has passed,
EPA looked to subpart 1 of part D of the
CAA in order to determine
Congressional intent. Section 179(d)
requires submittal of a plan revision
within one year after EPA publishes a
notice of a finding of failure to attain.
In case of the Imperial area, the
application of the deadline provided for
in section 179(d) has already resulted in
a significantly longer time for submittal
of the serious area plan than the
deadline that would otherwise have
applied. If the Imperial area had been
reclassified to serious prior to the end
of 2001, it would have been subject to
section 189(b)(2). As such, the deadline
for submittal of a serious area plan
would be 18 months from the date of the
reclassification. The effective date of the
reclassification here was September 10,
2004; therefore, the alternative to the
due date provided in section 179(d)
would result in the plan having been
due by March 10, 2006. Instead, the
area’s serious area plan is not due until
one year from publication of the Federal
Register notice of this action. EPA
knows of no legal theory that would
allow the Agency to provide the 5 years
apparently sought by the commenters

4. Economic Hardship
A number of commenters claimed that
an EPA finding of failure to attain
would result in adverse economic
consequences for Imperial County. One
commenter stated that the County has
one of the poorest economies in the
State, that EPA’s finding will place an
undue hardship on an economy that is
already on the brink of breaking, and
that the Agency should take economic
justice into account. Another
commenter suggested that another set of
government-imposed regulations would
place an unnecessary financial hardship
on area companies and could possibly
disrupt farming operations. Another
commenter cited the County’s high
unemployment rate that would increase
under severe emission control
requirements that undermine an
agriculture-dependent economy. The
commenters attributed these perceived
hardships to various factors they believe
to be related to a nonattainment finding:
the five percent and BACM
requirements applicable to serious PM–
10 attainment areas; the inability of the
County to control Mexican emissions;
and the prevalence of high wind natural
events. We address each of these factors
below.
rfrederick on PROD1PC67 with RULES
A. Five Percent and BACM
Requirements
A number of commenters opposed to
our proposed rule requested that EPA
reduce or remove entirely the proposed
requirement that Imperial County
submit a plan that achieves at least 5
percent annual reductions in PM–10 or
PM–10 precursor emissions as required
by CAA section 189(d). Some
commenters stated that this requirement
was not feasible or was too burdensome
for Imperial County. Another
commenter attributed severe economic
consequences to the serious area plan
requirements for expeditious
implementation of BACM.
Response: As stated above and in the
proposed rule, EPA is legally compelled
to finalize the nonattainment finding
with the result that the 5 percent
requirement of section 189(d) applies.
Under section 189(b)(1)(B), the serious
area PM–10 plan for the Imperial area is
required to provide for the expeditious
implementation of BACM. This
14 We note that subpart 4 of part D of title I which
contains the Act’s provisions specific to PM–10
does not have a provision that is analogous to
section 182(i) which grants EPA considerable
latitude to adjust submittal and other schedules
upon an ozone area’s reclassification. See also
section 187(f).
VerDate Aug<31>2005
13:17 Dec 10, 2007
Jkt 214001
requirement applies as a result of the
Imperial area’s reclassification to
serious which was mandated by the U.S.
Court of Appeals for the Ninth Circuit
in Sierra Club v. U.S. Environmental
Protection Agency, et al., 346 F.3d 955
(9th Cir. 2003), amended 352 F.3d 1186,
cert. denied, 542 U.S. 919 (2004).
Therefore BACM would have to be
implemented in the Imperial area even
in the absence of EPA’s finding that the
area failed to attain the PM–10
standards by the end of 2001.
EPA has defined BACM as: ‘‘* * *
The maximum degree of emissions
reduction of PM–10 and PM–10
precursors from a source * * * which is
determined on a case-by-case basis,
taking into account energy,
environmental, and economic impacts
and other costs, to be achievable for
such source through application of
production processes and available
methods, systems, and techniques for
control of each such pollutant.’’
Addendum at 42010. Therefore, while
EPA cannot take into account the
general economy of a nonattainment
area in determining what statutory
requirements apply in a serious
nonattainment area, it can consider the
cost of reducing emissions from a
particular source category and costs
incurred by similar sources that have
implemented emission reductions. In
addition, where the economic feasibility
of a measure depends on public
funding, an appropriate consideration is
past funding of similar activities as well
as availability of funding sources. Id. at
42013. Nevertheless, the CAA still
requires that the State submit a plan for
the Imperial area to, among other things,
attain the PM–10 NAAQS as
expeditiously as practicable. Moreover,
there are economic benefits to attaining
the NAAQS.
B. Mexican Emissions
Several commenters felt that the
economic hardship was a result of the
failure of EPA, in its proposed action, to
consider the fact that significant
amounts of particulate matter air
pollution in Imperial County emanate
from the large and growing city of
Mexicali, Mexico. Many commenters
opposing our proposed rule stated that
EPA ignored the fact that emissions
from Mexico are one of the reasons that
poor air quality exists in Imperial
County. Some commenters pointed out
that in the past, EPA has agreed that
Imperial County would have attained
the PM–10 NAAQS but for emissions
from Mexico (e.g., EPA’s approval of
CAA section 179B demonstration; 66 FR
53106, October 2001). Additionally, the
commenters claimed that the PM–10
PO 00000
Frm 00008
Fmt 4700
Sfmt 4700
plan needs to include consideration of
how emissions from Mexico impact the
attainment of the PM–10 NAAQS in
Imperial County.
Response: As explained in our
proposed rule, EPA has the
responsibility, pursuant to CAA sections
179(c) and 188(b)(2), to determine
within 6 months of the applicable
attainment date whether a PM–10
nonattainment area attained the 24-hour
NAAQS. Section 179(c)(1) of the Act
provides that determinations of failure
to attain are to be based upon an area’s
‘‘air quality as of the attainment date,’’
and section 188(b)(2) is consistent with
this requirement. EPA determines
whether an area’s air quality is meeting
the PM–10 NAAQS based upon air
quality data gathered at monitoring sites
in the nonattainment area and entered
into EPA’s AQS database. These data are
reviewed to determine the area’s air
quality status in accordance with EPA
regulations at 40 CFR part 50, appendix
K. 69 FR at 48836. Thus, neither the
CAA nor EPA regulations authorize the
Agency to consider the economic
circumstances of an area in making a
finding of attainment or nonattainment;
the determination is to be made solely
on the basis of the ambient air quality
in the area. Similarly, neither the CAA
nor EPA regulations allow EPA to ignore
the actual attainment status of an area
based on the influx of a pollutant from
another country. The attainment status
is intended to reflect the actual ambient
pollutant levels.
Section 179B(d) of the Act does allow
a moderate PM–10 nonattainment area
to avoid a reclassification to serious if
a state establishes to the satisfaction of
EPA that such an area would have
attained but for emissions emanating
from outside the United States. EPA did
approve such a demonstration for the
Imperial area but that approval was
overturned by the Ninth Circuit in
Sierra Club. See the discussion of this
case and its aftermath, 69 FR at 48835.
The State can, however, take the effect
of Mexican emissions into account in
addressing the CAA section 189(d)
attainment demonstration requirement.
See CAA section 179B(a) and the
Addendum at 42000–42002. In this
regard, note that section 179B does not
provide authority to exclude monitoring
data influenced by international
transport from regulatory
determinations related to attainment
and nonattainment. Thus, even if EPA
approves a section 179B ‘‘but for’’
demonstration for an area, the area
would continue to be designated as
nonattainment and subject to the
applicable requirements, including
nonattainment new source review,
E:\FR\FM\11DER1.SGM
11DER1
Federal Register / Vol. 72, No. 237 / Tuesday, December 11, 2007 / Rules and Regulations
nonattainment conformity, and other
measures prescribed for nonattainment
areas by the CAA.
rfrederick on PROD1PC67 with RULES
C. High Wind Events
Several commenters felt that the
economic hardship was a result of the
failure of EPA’s proposal to consider the
fact that significant amounts of
particulate matter air pollution in
Imperial County are the result of high
wind natural events. To support their
claims, commenters cited the Wind
Blown Dust Study.
Response: As discussed in our
response to comment #2, EPA will
under certain circumstances exclude
from attainment determinations ambient
PM–10 concentrations due to dust
raised by unusually high winds.
However, the State did not provide
documentation to support the flagged
high wind events from 1999–2001 and
the data are therefore not eligible for
exclusion here.15 Moreover, as noted
previously, even if the State had met the
provisions of EPA’s NEP that were
applicable at the time of the relevant
exceedances, the Imperial area would
not have attained the PM–10 standard
by December 31, 2001. The State can,
however, if it meets the requirements of
EPA’s exceptional events rule, take
future unusually high winds into
account in developing its CAA section
189(d) attainment demonstration. See 72
FR at 13565–13566 and 13576–13577.
5. Governmental Entities Should Work
Together
One commenter urged EPA to
immediately initiate a coordinated effort
involving the federal government,
Mexican government counterparts and
County officials to develop a federally
funded international plan to reduce
emissions. Another commenter
requested that, given the short time
provided in the CAA to develop and
submit a plan in this case, and the need
for the plan to consider international
transport, and perhaps,
nonanthropogenic sources, EPA be
involved early in the plan development
to ensure a timely plan submittal. One
commenter also stated that EPA needs
to work with other governmental
agencies to implement reasonable
policies for controlling PM–10 pollution
in the Imperial area.
Response: EPA agrees with the
commenters who encourage
governmental entities to work together
to address air pollution from Mexicali to
Imperial County. Reducing air pollution
anywhere along the U.S./Mexico border
requires binational cooperation and
15 See
footnote 11.
VerDate Aug<31>2005
13:17 Dec 10, 2007
Jkt 214001
coordination. Since 1983, EPA has been
working with the Mexican Government
and other stakeholders to reduce air
pollution along the border region.
Pursuant to the 1983 La Paz Agreement,
the U.S. and Mexico developed the
Border XXI Program and more recently
its successor, the Border 2012 U.S.Mexico Environmental Program.
Through these programs, EPA and
Mexico have worked together with
border tribal, state, and local
governments, as well as academia and
the general public, to improve our
understanding of the relative impacts of
contributing international sources of air
pollution and have developed and
implemented cost-effective control
strategies to reduce those emissions.
EPA continues to implement the
Border 2012 regionally-based border
program in the Mexicali-Imperial area.
We are active participants in the
Imperial/Mexicali Air Quality Task
Force which provides a forum for the
federal, state, and local governments to
discuss and analyze with community
stakeholders how to improve air quality
in the binational region. EPA continues
to fund numerous projects that study
and manage air pollution in various
crossborder airsheds like the Imperial/
Mexicali area. In addition to supporting
the District’s work to develop its PM–10
plan, EPA also provides direct funding
for the Mexicali-Imperial Air Quality
Task Force for binational public forums
to discuss the air quality of the
Mexicali-Imperial region, and to carry
out projects, including projects to
monitor air quality (especially in
Mexico), to demonstrate retrofit
equipment technologies for diesel
trucks, and to provide real time air
quality information to residents of
Imperial County.
Regarding the comment that EPA be
involved early in the development of
the air quality plan, we intend to
provide guidance and assistance to the
District and the State to support a
technically sound and timely submittal.
Lastly, regarding the need to develop
reasonable policies, EPA has worked
closely with the State and District to
improve the PM–10 emissions inventory
for the Imperial area, to develop a
natural events action plan (NEAP),16
and to develop rules to control certain
16 Under EPA’s NEP, if natural events caused
ambient concentrations of PM–10 that exceeded the
NAAQS in an area, the State was responsible for
developing a NEAP meeting certain specified
requirements to address future events. NEP at 5–8.
Under EPA’s exceptional events rule NEAPs are not
required, although similar requirements apply
under 40 CFR 51.920. 72 FR at 13581.

sources of fugitive dust in the
nonattainment area.
6. Finding of Failure To Attain Is
Mandatory Under the CAA and Fully
Supported by Ambient Monitoring Data
One commenter stated that the
proposal correctly reflects that the
Imperial Valley is a serious PM–10
nonattainment area that has missed its
attainment date and does not have an
extension of the attainment date in
place. The same commenter stated
further that EPA correctly assessed that
areas in situations like this have oneyear to submit a plan including a 5
percent plan. Another commenter who
agreed with EPA’s proposed rule stated
that EPA’s proposal had omitted some
statutory requirements (e.g., BACM
implemented expeditiously, major
source cutoffs), and reserved the right to
comment further on EPA’s proposed
action on the PM–10 SIP.
Response: EPA agrees with comments
supporting the proposal. We did not
include a comprehensive list of the CAA
requirements applicable to the Imperial
area, but expect the plan to address all
of them. See Section III below.
7. PM–10 Is Not a Regulated Pollutant
One commenter, California
Cattlemen’s Association (CCA), notes
that the U.S. Court of Appeals for the
District of Columbia Circuit in
American Trucking Ass’n v. Browner
vacated EPA’s 1997 PM–10 standard
because it included both coarse and fine
PM and therefore was ‘‘inherently
confounded.’’ CCA claims that the 1987
standard suffers from the same defect.
Therefore, CCA argues, there is no 1987
standard and, as a result, the Imperial
area cannot be out of compliance with
it. CCA states that if EPA’s response is
that the 1987 standard was re-instituted
in a final rule (65 FR 80776; December
22, 2000), there was not sufficient notice
as that rule was noticed within a ruling
for Ada County, Idaho (65 FR 39321;
June 26, 2000). Also, CCA believes that
because the same problem exists with
the 1987 standard as the 1997 standard,
simply reinstating the old standard was
not the court’s intention. Finally, CCA
discusses EPA’s then current process of
revising the PM NAAQS and finds,
among other things, similar
confounding problems in measurements
contained in studies that EPA is using
to consider setting its new NAAQS.
Response: In a portion of American
Trucking Ass’ns v. EPA, 175 F. 3d 1027,
not later reversed by the Supreme Court,
the D.C. Circuit held that, although
there was ‘‘ample support’’ for EPA’s
decision to regulate coarse-fraction
particles, EPA had not provided a
E:\FR\FM\11DER1.SGM
11DER1
rfrederick on PROD1PC67 with RULES
70228
Federal Register / Vol. 72, No. 237 / Tuesday, December 11, 2007 / Rules and Regulations
reasonable justification for its choice of
PM–10 as an indicator for coarse
particles, especially given that PM–10
includes not only coarse particles but
PM fine as well. 175 F. 3d at 1054–55.
Pursuant to the D.C. Circuit’s
decision, EPA deleted 40 CFR 50.6(d),
the regulatory provision controlling the
transition from the pre-existing 1987
PM–10 standards to the 1997 PM–10
standards. 65 FR 80776. EPA proposed
this deletion in the context of a
proposed rule to rescind a finding, made
prior to the D.C. Circuit’s vacatur of the
1997 standards, that the 1987 PM–10
standards no longer applied in Ada
County, Idaho. As EPA explained in the
proposed rule, the Ada County finding
was based on the existence of the 1997
standards as well as the transition
policy. Because the court vacated those
standards, leaving in place the finding
would have resulted in no federal
protection from high levels of coarse
particulate matter pollution. Finding
that result untenable, EPA concluded
that it was appropriate to restore the
pre-existing PM–10 standards with
respect to Ada County. 65 FR at 39323.
As is clear from the final rule, however,
the 1987 standards were never revoked
with respect to the rest of the country.
Therefore, although EPA deleted 40 CFR
50.6(d)(as required by the mandate of
ATA I), the pre-existing NAAQS
continue to apply. 65 FR at 80777. If
CCA believes that insufficient notice
was provided in connection with this
final action, it was required under CAA
section 307(b)(1) to file a petition for
review of that action in the U.S. Court
of Appeals within 60 days of December
22, 2000. CCA did not do so and is
therefore foreclosed from raising this
issue now.
Moreover, to the extent that CCA
raises issues with respect to the preexisting 1987 PM–10 standards, we note
that those standards were upheld in
Natural Resources Defense Council,
Inc., et al. v. EPA, et al., 902 F.2d 962
(D.C. Cir. 1990). In any case, the 1987
standards do not use PM–10 as an
indicator exclusively for coarse
particles, but rather are intended to
address both PM–2.5 and PM–10–2.5,
i.e. both fine and coarse particles. 52 FR
24634, 24639 (July 1, 1987). Thus, any
concerns that PM–10 may be an
inappropriate indicator for coarse
particles exclusively are inapplicable to
the 1987 standard.
When CCA submitted its comment
letter in 2004, EPA was in the process
of developing proposed regulations to
again address thoracic coarse particles.
The Agency subsequently finalized such
regulations in 2006. 71 FR 61144
(October 17, 2006). CCA’s concerns
VerDate Aug<31>2005
13:52 Dec 10, 2007
Jkt 214001
regarding new standards for PM–10,
including putative confounding
problems, were properly raised in the
context of that rulemaking. In fact,
challenges to the use of PM–10 as an
indicator for coarse particles, as well as
challenges to the scientific bases for the
2006 final rule have been raised by
various petitioners in the pending D.C.
Circuit cases (American Farm Bureau
Fed. et al. v. EPA and consolidated
cases) challenging the rule. CCA can,
and is, pursuing its concerns in that
forum.
III. Final Action
EPA is finding that the Imperial area
failed to attain the 24-hour PM–10
NAAQS by the December 31, 2001
attainment deadline and is requiring the
State to submit under section 189(d) of
the Act ‘‘plan revisions which provide
for attainment of the PM–10 air quality
standards and, from the date of such
submission until attainment, for an
annual reduction in PM–10 or PM–10
precursor emissions within the area of
not less than 5 percent of the amount of
such emissions as reported in the most
recent inventory prepared for such
area.’’ The plan must be submitted to
EPA no later than one year from the
publication of this final rule.
The pollutant-specific requirements
for moderate and serious PM–10
nonattainment areas are found in
section 189 of the CAA, and the general
planning and control requirements for
nonattainment plans are found in CAA
sections 110 and 172. In addition to the
attainment demonstration and 5 percent
annual reductions requirements
referenced above, the PM–10 plan for
the Imperial area must include the
following elements: 17
• Transportation conformity and
motor vehicle emissions budgets;
• Emissions inventories;
• Best available control measures for
significant sources of PM–10;
• Reasonably available control
measures for significant sources of PM–
10;
• Control requirements applicable to
major stationary sources of PM–10
precursors pursuant to section 189(e);
and
• Reasonable further progress and
quantitative milestones.
The District must also revise its new
source review (NSR) rule to reflect the
serious area definitions for major new
sources in CAA section 189(b)(3) and
must make any changes in its Title V
17 For a brief discussion of these requirements,
see our proposed approval of the San Joaquin
Valley PM–10 plan at 69 FR 5413, 5414 (February
4, 2004). See also the final rule at 69 FR 30006 (May

areas to 70 tpy for serious areas.
Revisions to the NSR and Title V rules
must also be submitted no later than one
year from the publication of this final
rule.
IV. Statutory and Executive Order
Reviews
Under Executive Order 12866 (58 FR
51735, October 4, 1993), this final action
is not a ‘‘significant regulatory action’’
and therefore is not subject to review by
the Office of Management and Budget.
For this reason, this action is also not
subject to Executive Order 13211,
‘‘Actions Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use’’ (66 FR 28355, May
22, 2001). This action merely makes a
determination based on air quality data
and does not impose any additional
requirements. Accordingly, the
Administrator certifies that this final
rule will not have a significant
economic impact on a substantial
number of small entities under the
Regulatory Flexibility Act (5 U.S.C. 601
et seq.). Because this rule does not
impose any additional enforceable duty,
it does not contain any unfunded
mandate or significantly or uniquely
affect small governments, as described
in the Unfunded Mandates Reform Act
of 1995 (Pub. L. 104–4). This rule also
does not have tribal implications
because it will not have a substantial
direct effect on one or more Indian
tribes, on the relationship between the
Federal Government and Indian tribes,
or on the distribution of power and
responsibilities between the Federal
Government and Indian tribes, as
specified by Executive Order 13175 (65
FR 67249, November 9, 2000). This
action also does not have Federalism
implications because it does not have
substantial direct effects on the States,
on the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132 (64 FR 43255,
August 10, 1999).
This action merely makes a
determination based on air quality data
and does not alter the relationship or
the distribution of power and
responsibilities established in the CAA.
Executive Order 12898 establishes a
Federal policy for incorporating
environmental justice into Federal
agency actions by directing agencies to
identify and address, as appropriate,
disproportionately high and adverse
E:\FR\FM\11DER1.SGM
11DER1
Federal Register / Vol. 72, No. 237 / Tuesday, December 11, 2007 / Rules and Regulations
human health or environmental effects
of their programs, policies, and
activities on minority and low-income
populations. Today’s action involves
determinations based on air quality
considerations. It will not have
disproportionately high and adverse
effects on any communities in the area,
including minority and low-income
communities. This rule also is not
subject to Executive Order 13045
‘‘Protection of Children from
Environmental Health Risks and Safety
Risks’’(62 FR 19885, April 23, 1997),
because it is not economically
significant. 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. This
rule does not impose an information

Finding of Failure To Attain; California--Imperial Valley
Nonattainment Area; PM-10
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is finding that the Imperial Valley serious PM-10
nonattainment area did not attain the 24-hour particulate matter (PM-
10) National Ambient Air Quality Standard (NAAQS) by the deadline
mandated in the Clean Air Act (CAA), December 31, 2001. In response to
this finding, the State of California must submit a revision to the
California State Implementation Plan (SIP) that provides for attainment
of the PM-10 standard in the Imperial Valley area and at least five
percent annual reductions in PM-10 or PM-10 precursor emissions until
attainment as required by CAA section 189(d). The State must submit the
SIP revision by December 11, 2008.
DATES: Effective Date: This finding is effective on January 10, 2008.
ADDRESSES: EPA has established docket number EPA-R09-OAR-2006-0583 for
this action. The index to the docket is available electronically at

SUPPLEMENTARY INFORMATION: Throughout this document ``we,'' ``us,'' and
``our'' refer to EPA.
I. Background
On August 11, 2004, EPA reclassified under the Clean Air Act (CAA
or the Act) the Imperial Valley PM-10 nonattainment area (Imperial
area) from moderate to serious in response to the opinion of the U.S.
Court of Appeals for the Ninth Circuit in Sierra Club v. United States
Environmental Protection Agency, et al., 346 F.3d 955 (9th Cir. 2003),
amended 352 F.3d 1186, cert. denied, 542 U.S. 919 (2004). See 69 FR
48792 (August 11, 2004).
Also on August 11, 2004 (69 FR 48835), EPA proposed to find under
the CAA that the Imperial area failed to attain the annual \1\ and 24-
hour PM-10 standards by the serious area deadline of December 31, 2001.
Our proposed finding of failure to attain was based on monitored air
quality data for the PM-10 NAAQS from January 1999 through December
2001. A summary of these data was provided in the proposed rule and is
not reproduced here.
---------------------------------------------------------------------------
\1\ Effective December 18, 2006, EPA revoked the annual PM-10
standard. 71 FR 61144 (October 17, 2006). References to the annual
standard in this proposed rule are for historical purposes only. EPA
is not taking any regulatory action with regard to this former
standard.
---------------------------------------------------------------------------
EPA has the responsibility, pursuant to sections 179(c) and
188(b)(2) of the Act, of determining within 6 months of the applicable
attainment date (i.e., June 30, 2002), whether the Imperial area
attained the PM-10 NAAQS. Because the June 30, 2002 date has passed,
EPA is required to make that determination as soon as practicable.
Delaney v. EPA, 898 F.2d 687 (9th Cir. 1990).
Section 179(c)(1) of the Act provides that attainment
determinations are to be based upon an area's ``air quality as of
[[Page 70223]]
the attainment date,'' and section 188(b)(2), which is specific to PM-
10, is consistent with that requirement. EPA determines whether an
area's air quality is meeting the PM-10 NAAQS based upon air quality
data gathered at monitoring sites in the nonattainment area and entered
into EPA's Air Quality System (AQS) database. These data are reviewed
to determine the area's air quality status in accordance with EPA
regulations at 40 CFR part 50, appendix K.\2\ For details about EPA's
proposed failure to attain finding, please see the proposed rule.
---------------------------------------------------------------------------
\2\ Pursuant to appendix K, attainment of the 24-hour PM-10
NAAQS is achieved when the expected number of exceedances of the 24-
hour NAAQS (150 mg/m\3\) per year at each monitoring site is less
than or equal to one. A total of three consecutive years of clean
air quality data is generally necessary to show attainment of the
24-hour standard for PM-10. A complete year of air quality data, as
referred to in 40 CFR part 50, appendix K, is comprised of all four
calendar quarters with each quarter containing data from at least 75
percent of the scheduled sampling days.
---------------------------------------------------------------------------
II. EPA's Responses to Comments on the Proposed Rule
EPA received eight comment letters on the proposed finding.
Summaries of the comments and EPA's responses are set forth below.
1. Retroactive Finding of Failure To Attain Is Unlawful
The Imperial County Air Pollution Control District (District or
ICAPCD) claimed that EPA's proposed finding that the Imperial area
failed to attain the serious area deadline of December 31, 2001, issued
the same day as the reclassification of the area from moderate to
serious, constitutes an unlawful and unjust retroactive rulemaking in
that the area would be at once reclassified and punished for failing to
meet the requirements of the new classification. The District strongly
urged EPA to refrain from finalizing any rule that makes a
nonattainment finding under these circumstances.
In support of its position that this type of rulemaking is illegal
under the Administrative Procedure Act (APA), the District cited a
number of federal court decisions and EPA rulemakings. The District
believes that these decisions and rulemakings support its position that
the nonattainment finding could create liabilities and penalties for
missing long past deadlines associated with serious nonattainment areas
and/or impose more rigorous requirements than would otherwise be
justified, e.g., the requirement under CAA section 189(d) to submit a
revised plan in 12 months rather than the 18 months allowed under
section 189(b)(2) when a moderate area fails to meet its attainment
deadline.
Response: At bottom, the argument that the District makes is that
if the Imperial area had been reclassified as the CAA envisioned, the
area would not now be subject to the requirements of section 189(d). In
other words, EPA would have found that the area failed to attain the
moderate area deadline of December 31, 1994 well before the serious
area deadline of December 31, 2001. Consequently, the serious area plan
for the Imperial area would have been due 18 months from the
reclassification pursuant to section 189(b)(2) instead of being subject
to the 12-month deadline in section 189(d). Furthermore, the argument
goes, if the State had been able to demonstrate that attainment by 2001
was impracticable the area would have been able to avail itself of the
attainment date extension provisions of section 188(e),\3\ thereby
potentially avoiding both the substantive and procedural requirements
of section 189(d) entirely. Instead, the District argues, EPA's action
has illegally circumvented the statutory scheme by precluding the area
from taking advantage of allegedly more lenient submittal and
substantive requirements.
---------------------------------------------------------------------------
\3\ Section 188(e) provides for a one-time extension of the
attainment deadline for serious PM-10 nonattainment areas if certain
conditions are met. However such an extension cannot extend beyond
December 31, 2006. Because that date has now passed, a section
188(e) extension for the Imperial area is unavailable under any
circumstances. Nevertheless we address in this final rule the
comments we received relating to section 188(e) insofar as doing so
enables us to fully respond to those comments. For example, here a
discussion of section 188(e) is relevant to the District's claim,
among others, that EPA's action subjects the area to more stringent
requirements than otherwise would have been imposed.
---------------------------------------------------------------------------
The cases and EPA actions cited by the District, however, do not
support its position. With respect to the Imperial PM-10 nonattainment
area, EPA reclassified it from moderate to serious and immediately
proposed to find that the area had failed to attain the serious area
deadline. The result of these actions is that the State will be
required to submit in the future a plan for the area under CAA section
189(d). In contrast, in Sierra Club v. EPA, 356 F.3d 296 (D.C. Cir.
2004), EPA set a prospective submittal date pursuant to CAA section
182(i) upon reclassification of the Washington, D.C. ozone
nonattainment area from serious to severe because the severe area plan
submittal deadline in the CAA had already passed. Similarly, in several
other ozone reclassification actions, EPA also determined that where a
submittal date had passed and was therefore impossible to meet, the
Agency could administratively establish a later date. EPA's reasoning
in these cases was that to do otherwise would have subjected these
areas to an immediate finding of failure to submit and the immediate
initiation of sanctions clocks.\4\
---------------------------------------------------------------------------
\4\ See Washington, DC, 68 FR 3410, 3413 (January 24, 2003). See
also Santa Barbara, California, 62 FR 65025 (December 10, 1997);
Phoenix, Arizona, 62 FR 60001 (November 6, 1997); and Dallas-Fort
Worth, Texas, 63 FR 8128 (February 18, 1998).
---------------------------------------------------------------------------
In the case of Washington, DC, EPA stated in its final rule that
``the Administrative Procedure Act * * * requires that before a rule
takes effect, persons affected will have advance notification of its
requirements. A failure to meet an obligation, especially one
accompanied by sanctions, cannot occur in advance of the imposition of
that obligation.'' 68 FR at 3414. The Court of Appeals agreed, quoting
EPA, ``that adopting petitioner's suggestion [that EPA retain the
original submittal deadlines] `would give the reclassification
retroactive effect by holding the States in default of their submission
obligations before the events necessary to trigger that obligation
(reclassification) * * * occurred.' '' 356 F.3d at 309.
In Sierra Club v. Whitman, 130 F.Supp. 2d. 78 (D.D.C. 2001), cited
by the D.C. Circuit in Sierra Club v. EPA above and the District in its
comment letter, and affirmed in Sierra Club v. Whitman, 285 F.3d 63, 68
(D.C. Cir 2002), the plaintiffs sought to compel EPA to backdate a
nonattainment determination to the date on which the Agency was
statutorily required to make such a determination. In affirming the
District Court's denial of the relief sought, the D.C. Circuit opined
that:
Although EPA failed to make the nonattainment determination
within the statutory time frame, Sierra Club's proposed solution
only makes the matter worse. Retroactive relief would likely impose
large costs on the States, which would face fines and suits for not
implementing air pollution prevention plans in 1997, even though
they were not on notice at the time.
Id. at 68.\5\
---------------------------------------------------------------------------
\5\ The District also cites Georgetown University Hospital v.
Bowen in which a federal agency reissued a procedurally defective
rule and gave it retroactive effect. Both the D.C. Circuit and the
U.S. Supreme Court invalidated the action, finding, among other
things, that under the APA legislative rules must be given future
effect only. 821 F.2d 759 (D.C. Cir. 1987); 488 U.S. 204 (1988).
---------------------------------------------------------------------------
In the instant case, however, by giving the State the benefit of a
future plan submittal deadline for the Imperial area, EPA's action is
consistent with the holdings of the cases and with the EPA regulatory
actions cited by the District.
[[Page 70224]]
Under section 189(d), the State must submit a plan revision for the
Imperial area ``within 12 months after the applicable attainment date.
* * *'' That date was December 31, 2002. However, because, at the time
of EPA's proposed finding of failure to attain, that date had already
passed, EPA proposed that the section 189(d) plan revision be due
``within one year of publication of a final finding of nonattainment
pursuant to CAA section 179(d).'' 69 FR at 48837. Thus, rather than
invoking the long past submittal deadline in section 189(d), EPA looked
to another provision of the Act to supply a prospective deadline. In
doing so, EPA alleviated the problem of imposing a retroactive deadline
without imposing immediate sanctions.
While it is true, as the District points out, that a serious PM-10
area proceeding initially under section 189(b) instead of section
189(d) would in theory have had more time to submit a plan (18 rather
than 12 months), in both instances the submittal deadlines are
prospective and not retroactive. Furthermore, as we point out in our
response to comment 3 below, the section 189(d) plan that the
State is now required to submit is actually due later than the serious
area plan would have been due under the scenario preferred by the
District. Therefore, the retroactive penalty the District complains of
with respect to the plan submittal deadline simply does not exist.
Moreover, while it is also true that, as a result of EPA's
nonattainment finding, the Imperial area must comply with the
substantive requirements of CAA section 189(d) instead of those of
section 188(e), this consequence cannot be construed as ``punishment.''
Under both sections 189(d) and 188(e), implementation of best available
control measures (BACM) under section 189(b)(1) and attainment of the
PM-10 standards as expeditiously as practicable are required. In
addition, while the respective substantive requirements of sections
188(e) and 189(d) are different, neither are necessarily more onerous
than the other. See Corrected Brief of Respondent EPA, pages 40-42, in
Association of Irritated Residents, et al. v. EPA, 423 F.3d 989 (9th
Cir. 2005). Only if the State fails to submit the new plan in the
future could sanctions come into play. Thus the substantive
consequences here of EPA's nonattainment finding are not in fact
retroactive, nor do they impose a penalty.
For the reasons discussed in its proposed finding, EPA is legally
compelled to finalize the nonattainment finding with the result that
section 189(d) applies to the Imperial area. The section 189(d) plan is
due within one year of publication of this final finding of
nonattainment.\6\
---------------------------------------------------------------------------
\6\ Our rationale for this plan submittal deadline is discussed
in the proposed rule. See at 69 FR at 48837.
---------------------------------------------------------------------------
2. Waive the Attainment Date and Related Requirements
Several commenters suggested that instead of finding that the
Imperial area failed to attain the serious area attainment date, EPA
should waive that date and the related submittal requirements and
penalties to reduce the burden of the Agency's action on Imperial
County. While two commenters who suggested this approach did not
describe EPA's legal authority to grant a waiver, one commenter, the
District, cited CAA section 188(f) as providing EPA with the authority
to waive a specific attainment date where the Agency determines that
nonanthropogenic sources contribute significantly to violations in the
area and to waive any requirement applicable to any serious PM-10 area
where anthropogenic sources do not contribute significantly to
violations. The District stated that in the Imperial area, dry soil
from vast barren lands are entrained by high winds producing an impact
on the monitors. The District asserted that EPA has determined that
this type of dust raised by high wind events constitutes a
nonanthropogenic source of PM-10 pursuant to section 188(f) and, citing
a May 30, 1996 EPA memorandum, that monitoring data impacted by such
events may be excluded from consideration in attainment decisions.
Response: Congress recognized in the Clean Air Act that there may
be areas where the NAAQS may never be attained because of PM-10
emissions from nonanthropogenic sources, and that the imposition in
such areas of certain state planning requirements may not be justified.
Therefore, under section 188(f), Congress provided a means for EPA to
waive a specific date for attainment and certain control and planning
requirements when specified conditions are met in a nonattainment area.
Section 188(f) provides two types of waivers. First, EPA may, on a
case-by-case basis, waive any PM-10 nonattainment planning requirement
applicable to any serious nonattainment area where EPA determines that
anthropogenic sources of PM-10 do not contribute significantly to
violation of the standards in the area. Second, EPA may waive a
specific date for attainment of the standards where EPA determines that
nonanthropogenic sources of PM-10 contribute significantly to the
violation of the standards in the area.\7\ In the Addendum, EPA set
forth threshold levels for determining whether areas qualify for
waivers under section 188(f). Addendum at 42004-42005.
---------------------------------------------------------------------------
\7\ 59 FR 41998 (August 16, 1994) (``State Implementation Plans
for Serious PM-10 Nonattainment Areas, and Attainment Date Waivers
for PM-10 Nonattainment Areas Generally; Addendum to the General
Preamble for the Implementation of Title I of the Clean Air Act
Amendments of 1990'' (Addendum)).
---------------------------------------------------------------------------
In its comment letter, the District included and discussed a report
\8\ that it characterized as showing that windblown dust from barren
lands represents over 92% or 792 tons per day (tpd) of the total PM-10
inventory in Imperial County. The District maintained that ``high winds
frequently entrain large amounts of this dry soil into the ambient air,
producing a documented impact on County monitors.'' As a result of
comments provided to the District by EPA and the California Air
Resources Board (CARB), the Windblown Dust Study was revised in
2005.\9\ The Revised Study concluded, among other things, that there
are 157 tpd of fugitive dust emissions from barren lands. Revised Study
at A-15. The Windblown Dust Study and the Revised Study are primarily
inventories of windblown dust emissions in Imperial County. These
documents do not address the requirements of section 188(f) and EPA's
guidance on that provision. Therefore they do not provide sufficient
analysis and documentation to support a waiver of either the December
31, 2001 attainment deadline or any of the serious area requirements.
However, the section 188(f) waivers, if the conditions for them can be
met, are available to the State in the context of the section 189(d)
serious area plan.\10\

\10\ With respect to the section 188(f) waiver of serious area
requirements, EPA cautions that while the District in its comment
appears to characterize the predominant issue in the Imperial area
to be nonanthropogenic sources, the District has identified
anthropogenic PM-10 source categories that contribute significantly
to peak 24-hour average PM-10 values in the area. See Regulation
VIII BACM Analysis.
---------------------------------------------------------------------------
The May 30, 1996 memorandum cited by the District is entitled
``Areas Affected by PM-10 Natural Events'' and
[[Page 70225]]
is from Mary Nichols, Assistant Administrator for Air and Radiation to
EPA Regional Division Directors (Natural Events Policy or NEP). This
policy provides, among other things, that EPA believes it is
appropriate to exclude air quality data attributable to uncontrollable
natural events from the Agency's decisions regarding an area's
attainment status. NEP at p. 2.\11\ In the case of high winds, under
the NEP EPA considers ambient PM-10 concentrations due to dust raised
by unusually high winds as due to uncontrollable natural events (and
thus excludable from attainment determinations) if either (1) the dust
originated from nonanthropogenic sources or (2) the dust originated
from anthropogenic sources controlled with BACM. NEP at pp. 4-5.
---------------------------------------------------------------------------
\11\ On March 22, 2007, EPA issued a final rule, intended to
replace the NEP, governing the review and handling of air quality
data influenced by exceptional events. 72 FR 13560. The rule became
effective on May 21, 2007 and is codified at 40 CFR 50.1, 50.14 and
51.920. 72 FR 13560, 13580-13581. However, as discussed below, the
1999-2001 data relevant to this final action are not eligible for
exclusion under the transition policy for the rule because the State
did not meet the provisions of the NEP that were applicable at the
time of the exceedances. See 72 FR 49046, 49048 (August 27, 2007).
---------------------------------------------------------------------------
The NEP sets forth a process for declaring an exceedance as due to
natural events and for documenting a natural events claim. NEP at pp.
7-10. Where a state believes that natural events caused the NAAQS
exceedances it must establish through supporting documentation a clear
causal relationship between the exceedance and the natural event. The
amount and type of documentation must be sufficient to demonstrate that
the natural event occurred and that it impacted a particular monitoring
site in such a way as to cause the PM-10 concentrations measured. The
documentation also should provide evidence that, absent the natural
event emissions, concentrations at the monitoring site would not cause
an exceedance.
Under the NEP, when air quality data affected by a natural event
are submitted to EPA for inclusion into the AIRS database,\12\ the
state is to request that a flag be placed on the data to indicate that
a natural event was involved. NEP at 8-9. A number of exceedances in
1999-2001 in the Imperial area were flagged as high wind and other
natural events. Under the NEP, the documentation supporting a natural
events flag was required to be submitted no later than 180 days from
the time the exceedance occurred. However no documentation with respect
to the 1999-2001 exceedances was submitted to EPA.\13\ Because the
State did not comply with the provisions of the NEP, the flagged 1999-
2001 data cannot be excluded as affected by natural events from EPA's
determination of whether the Imperial area attained the PM-10 standard
by December 31, 2001.
---------------------------------------------------------------------------
\12\ The AIRS database is the predecessor to the AQS database.
\13\ Note that even if adequate documentation had been submitted
for the flagged events, the Imperial area would not have attained
the PM-10 standard because of the number of unflagged exceedances.

Spreadsheet, Bob Pallarino, EPA.
---------------------------------------------------------------------------
3. EPA Should Grant a 5-Year Extension To Allow More Time To Develop
Plan
Several commenters opposing our proposed action stated that our
proposed time frame for the development and submittal of a serious area
PM-10 plan, including a CAA section 189(d) plan, was too short, and
that EPA should grant a 5-year extension of the attainment date for the
Imperial area to provide time for preparation, submittal and
consideration of an attainment demonstration. Of the commenters making
this request, only the District cited any legal authority for a 5-year
extension: ``* * * The District requests that EPA withdraw its proposed
12-month deadline for the County's serious area SIP submittal * * * and
instead grant a five-year extension under Section 188(e) to allow
sufficient time for preparation, submittal and consideration of the
County's final PM-10 attainment demonstration.'' The District
characterized the 12-month plan submittal schedule as ``abbreviated''
and as a ``penalty.'' One of the commenters suggesting the 5-year
extension approach urged EPA to utilize our discretion under the CAA to
extend the time allowed to prepare a plan so that unwarranted
imposition of additional measures could be avoided.
Another commenter stated that although a preferable outcome would
have been an extension of the attainment date, it was clear that no
attainment date extension was in place, and thus, the finding of
failure to attain by EPA was mandatory under the Clean Air Act with the
one-year deadline for an attainment demonstration.
Response: CAA section 188(e) provides that, upon application by a
state, EPA may extend the attainment deadline for a serious PM-10
nonattainment area no more than 5 years beyond, in this case, December
31, 2001, if: (a) Attainment by that date would be impracticable; (b)
the state has complied with all requirements and commitments in the
implementation plan for the area; and (c) the state demonstrates that
the plan contains the most stringent measures (MSM) in the plan of any
state or are achieved in practice in any state, and can feasibly be
implemented in the area. The state must submit at the time of its
extension application a demonstration of attainment by the most
expeditious alternative date practicable.
As stated above, the Imperial area is no longer eligible for an
attainment date extension under section 188(e) because that extension
cannot extend beyond 2006. Regardless, the attainment date extension
provided for in section 188(e) does not relate in any way to the
submittal date for a serious area plan. Rather, under the Act,
submittal dates for serious area PM-10 plans are initially governed by
subpart 4 of part D of the CAA, i.e, either by section 189(b)(2) or
189(d). As explained in the proposed rule, EPA believes that section
189(d) applies to the Imperial area's situation. 69 FR at 48837. In the
first instance, EPA looked to this provision, which applies exclusively
to PM-10 nonattainment areas, for the applicable submittal date for the
Imperial area's section 189(d) plan. Because the deadline for plan
submittal under that section, December 31, 2002 has passed, EPA looked
to subpart 1 of part D of the CAA in order to determine Congressional
intent. Section 179(d) requires submittal of a plan revision within one
year after EPA publishes a notice of a finding of failure to attain.
In case of the Imperial area, the application of the deadline
provided for in section 179(d) has already resulted in a significantly
longer time for submittal of the serious area plan than the deadline
that would otherwise have applied. If the Imperial area had been
reclassified to serious prior to the end of 2001, it would have been
subject to section 189(b)(2). As such, the deadline for submittal of a
serious area plan would be 18 months from the date of the
reclassification. The effective date of the reclassification here was
September 10, 2004; therefore, the alternative to the due date provided
in section 179(d) would result in the plan having been due by March 10,
2006. Instead, the area's serious area plan is not due until one year
from publication of the Federal Register notice of this action. EPA
knows of no legal theory that would allow the Agency to provide the 5
years apparently sought by the commenters
[[Page 70226]]
for the development and submittal of a serious area PM-10 plan.\14\
---------------------------------------------------------------------------
\14\ We note that subpart 4 of part D of title I which contains
the Act's provisions specific to PM-10 does not have a provision
that is analogous to section 182(i) which grants EPA considerable
latitude to adjust submittal and other schedules upon an ozone
area's reclassification. See also section 187(f).
---------------------------------------------------------------------------
4. Economic Hardship
A number of commenters claimed that an EPA finding of failure to
attain would result in adverse economic consequences for Imperial
County. One commenter stated that the County has one of the poorest
economies in the State, that EPA's finding will place an undue hardship
on an economy that is already on the brink of breaking, and that the
Agency should take economic justice into account. Another commenter
suggested that another set of government-imposed regulations would
place an unnecessary financial hardship on area companies and could
possibly disrupt farming operations. Another commenter cited the
County's high unemployment rate that would increase under severe
emission control requirements that undermine an agriculture-dependent
economy. The commenters attributed these perceived hardships to various
factors they believe to be related to a nonattainment finding: the five
percent and BACM requirements applicable to serious PM-10 attainment
areas; the inability of the County to control Mexican emissions; and
the prevalence of high wind natural events. We address each of these
factors below.
A. Five Percent and BACM Requirements
A number of commenters opposed to our proposed rule requested that
EPA reduce or remove entirely the proposed requirement that Imperial
County submit a plan that achieves at least 5 percent annual reductions
in PM-10 or PM-10 precursor emissions as required by CAA section
189(d). Some commenters stated that this requirement was not feasible
or was too burdensome for Imperial County. Another commenter attributed
severe economic consequences to the serious area plan requirements for
expeditious implementation of BACM.
Response: As stated above and in the proposed rule, EPA is legally
compelled to finalize the nonattainment finding with the result that
the 5 percent requirement of section 189(d) applies. Under section
189(b)(1)(B), the serious area PM-10 plan for the Imperial area is
required to provide for the expeditious implementation of BACM. This
requirement applies as a result of the Imperial area's reclassification
to serious which was mandated by the U.S. Court of Appeals for the
Ninth Circuit in Sierra Club v. U.S. Environmental Protection Agency,
et al., 346 F.3d 955 (9th Cir. 2003), amended 352 F.3d 1186, cert.
denied, 542 U.S. 919 (2004). Therefore BACM would have to be
implemented in the Imperial area even in the absence of EPA's finding
that the area failed to attain the PM-10 standards by the end of 2001.
EPA has defined BACM as: ``* * * The maximum degree of emissions
reduction of PM-10 and PM-10 precursors from a source * * * which is
determined on a case-by-case basis, taking into account energy,
environmental, and economic impacts and other costs, to be achievable
for such source through application of production processes and
available methods, systems, and techniques for control of each such
pollutant.'' Addendum at 42010. Therefore, while EPA cannot take into
account the general economy of a nonattainment area in determining what
statutory requirements apply in a serious nonattainment area, it can
consider the cost of reducing emissions from a particular source
category and costs incurred by similar sources that have implemented
emission reductions. In addition, where the economic feasibility of a
measure depends on public funding, an appropriate consideration is past
funding of similar activities as well as availability of funding
sources. Id. at 42013. Nevertheless, the CAA still requires that the
State submit a plan for the Imperial area to, among other things,
attain the PM-10 NAAQS as expeditiously as practicable. Moreover, there
are economic benefits to attaining the NAAQS.
B. Mexican Emissions
Several commenters felt that the economic hardship was a result of
the failure of EPA, in its proposed action, to consider the fact that
significant amounts of particulate matter air pollution in Imperial
County emanate from the large and growing city of Mexicali, Mexico.
Many commenters opposing our proposed rule stated that EPA ignored the
fact that emissions from Mexico are one of the reasons that poor air
quality exists in Imperial County. Some commenters pointed out that in
the past, EPA has agreed that Imperial County would have attained the
PM-10 NAAQS but for emissions from Mexico (e.g., EPA's approval of CAA
section 179B demonstration; 66 FR 53106, October 2001). Additionally,
the commenters claimed that the PM-10 plan needs to include
consideration of how emissions from Mexico impact the attainment of the
PM-10 NAAQS in Imperial County.
Response: As explained in our proposed rule, EPA has the
responsibility, pursuant to CAA sections 179(c) and 188(b)(2), to
determine within 6 months of the applicable attainment date whether a
PM-10 nonattainment area attained the 24-hour NAAQS. Section 179(c)(1)
of the Act provides that determinations of failure to attain are to be
based upon an area's ``air quality as of the attainment date,'' and
section 188(b)(2) is consistent with this requirement. EPA determines
whether an area's air quality is meeting the PM-10 NAAQS based upon air
quality data gathered at monitoring sites in the nonattainment area and
entered into EPA's AQS database. These data are reviewed to determine
the area's air quality status in accordance with EPA regulations at 40
CFR part 50, appendix K. 69 FR at 48836. Thus, neither the CAA nor EPA
regulations authorize the Agency to consider the economic circumstances
of an area in making a finding of attainment or nonattainment; the
determination is to be made solely on the basis of the ambient air
quality in the area. Similarly, neither the CAA nor EPA regulations
allow EPA to ignore the actual attainment status of an area based on
the influx of a pollutant from another country. The attainment status
is intended to reflect the actual ambient pollutant levels.
Section 179B(d) of the Act does allow a moderate PM-10
nonattainment area to avoid a reclassification to serious if a state
establishes to the satisfaction of EPA that such an area would have
attained but for emissions emanating from outside the United States.
EPA did approve such a demonstration for the Imperial area but that
approval was overturned by the Ninth Circuit in Sierra Club. See the
discussion of this case and its aftermath, 69 FR at 48835. The State
can, however, take the effect of Mexican emissions into account in
addressing the CAA section 189(d) attainment demonstration requirement.
See CAA section 179B(a) and the Addendum at 42000-42002. In this
regard, note that section 179B does not provide authority to exclude
monitoring data influenced by international transport from regulatory
determinations related to attainment and nonattainment. Thus, even if
EPA approves a section 179B ``but for'' demonstration for an area, the
area would continue to be designated as nonattainment and subject to
the applicable requirements, including nonattainment new source review,
[[Page 70227]]
nonattainment conformity, and other measures prescribed for
nonattainment areas by the CAA.
C. High Wind Events
Several commenters felt that the economic hardship was a result of
the failure of EPA's proposal to consider the fact that significant
amounts of particulate matter air pollution in Imperial County are the
result of high wind natural events. To support their claims, commenters
cited the Wind Blown Dust Study.
Response: As discussed in our response to comment 2, EPA
will under certain circumstances exclude from attainment determinations
ambient PM-10 concentrations due to dust raised by unusually high
winds. However, the State did not provide documentation to support the
flagged high wind events from 1999-2001 and the data are therefore not
eligible for exclusion here.\15\ Moreover, as noted previously, even if
the State had met the provisions of EPA's NEP that were applicable at
the time of the relevant exceedances, the Imperial area would not have
attained the PM-10 standard by December 31, 2001. The State can,
however, if it meets the requirements of EPA's exceptional events rule,
take future unusually high winds into account in developing its CAA
section 189(d) attainment demonstration. See 72 FR at 13565-13566 and
13576-13577.
---------------------------------------------------------------------------
\15\ See footnote 11.
---------------------------------------------------------------------------
5. Governmental Entities Should Work Together
One commenter urged EPA to immediately initiate a coordinated
effort involving the federal government, Mexican government
counterparts and County officials to develop a federally funded
international plan to reduce emissions. Another commenter requested
that, given the short time provided in the CAA to develop and submit a
plan in this case, and the need for the plan to consider international
transport, and perhaps, nonanthropogenic sources, EPA be involved early
in the plan development to ensure a timely plan submittal. One
commenter also stated that EPA needs to work with other governmental
agencies to implement reasonable policies for controlling PM-10
pollution in the Imperial area.
Response: EPA agrees with the commenters who encourage governmental
entities to work together to address air pollution from Mexicali to
Imperial County. Reducing air pollution anywhere along the U.S./Mexico
border requires binational cooperation and coordination. Since 1983,
EPA has been working with the Mexican Government and other stakeholders
to reduce air pollution along the border region. Pursuant to the 1983
La Paz Agreement, the U.S. and Mexico developed the Border XXI Program
and more recently its successor, the Border 2012 U.S.-Mexico
Environmental Program. Through these programs, EPA and Mexico have
worked together with border tribal, state, and local governments, as
well as academia and the general public, to improve our understanding
of the relative impacts of contributing international sources of air
pollution and have developed and implemented cost-effective control
strategies to reduce those emissions.
EPA continues to implement the Border 2012 regionally-based border
program in the Mexicali-Imperial area. We are active participants in
the Imperial/Mexicali Air Quality Task Force which provides a forum for
the federal, state, and local governments to discuss and analyze with
community stakeholders how to improve air quality in the binational
region. EPA continues to fund numerous projects that study and manage
air pollution in various crossborder airsheds like the Imperial/
Mexicali area. In addition to supporting the District's work to develop
its PM-10 plan, EPA also provides direct funding for the Mexicali-
Imperial Air Quality Task Force for binational public forums to discuss
the air quality of the Mexicali-Imperial region, and to carry out
projects, including projects to monitor air quality (especially in
Mexico), to demonstrate retrofit equipment technologies for diesel
trucks, and to provide real time air quality information to residents
of Imperial County.
Regarding the comment that EPA be involved early in the development
of the air quality plan, we intend to provide guidance and assistance
to the District and the State to support a technically sound and timely
submittal.
Lastly, regarding the need to develop reasonable policies, EPA has
worked closely with the State and District to improve the PM-10
emissions inventory for the Imperial area, to develop a natural events
action plan (NEAP),\16\ and to develop rules to control certain sources
of fugitive dust in the nonattainment area.
---------------------------------------------------------------------------
\16\ Under EPA's NEP, if natural events caused ambient
concentrations of PM-10 that exceeded the NAAQS in an area, the
State was responsible for developing a NEAP meeting certain
specified requirements to address future events. NEP at 5-8. Under
EPA's exceptional events rule NEAPs are not required, although
similar requirements apply under 40 CFR 51.920. 72 FR at 13581.
---------------------------------------------------------------------------
6. Finding of Failure To Attain Is Mandatory Under the CAA and Fully
Supported by Ambient Monitoring Data
One commenter stated that the proposal correctly reflects that the
Imperial Valley is a serious PM-10 nonattainment area that has missed
its attainment date and does not have an extension of the attainment
date in place. The same commenter stated further that EPA correctly
assessed that areas in situations like this have one-year to submit a
plan including a 5 percent plan. Another commenter who agreed with
EPA's proposed rule stated that EPA's proposal had omitted some
statutory requirements (e.g., BACM implemented expeditiously, major
source cutoffs), and reserved the right to comment further on EPA's
proposed action on the PM-10 SIP.
Response: EPA agrees with comments supporting the proposal. We did
not include a comprehensive list of the CAA requirements applicable to
the Imperial area, but expect the plan to address all of them. See
Section III below.
7. PM-10 Is Not a Regulated Pollutant
One commenter, California Cattlemen's Association (CCA), notes that
the U.S. Court of Appeals for the District of Columbia Circuit in
American Trucking Ass'n v. Browner vacated EPA's 1997 PM-10 standard
because it included both coarse and fine PM and therefore was
``inherently confounded.'' CCA claims that the 1987 standard suffers
from the same defect. Therefore, CCA argues, there is no 1987 standard
and, as a result, the Imperial area cannot be out of compliance with
it. CCA states that if EPA's response is that the 1987 standard was re-
instituted in a final rule (65 FR 80776; December 22, 2000), there was
not sufficient notice as that rule was noticed within a ruling for Ada
County, Idaho (65 FR 39321; June 26, 2000). Also, CCA believes that
because the same problem exists with the 1987 standard as the 1997
standard, simply reinstating the old standard was not the court's
intention. Finally, CCA discusses EPA's then current process of
revising the PM NAAQS and finds, among other things, similar
confounding problems in measurements contained in studies that EPA is
using to consider setting its new NAAQS.
Response: In a portion of American Trucking Ass'ns v. EPA, 175 F.
3d 1027, not later reversed by the Supreme Court, the D.C. Circuit held
that, although there was ``ample support'' for EPA's decision to
regulate coarse-fraction particles, EPA had not provided a
[[Page 70228]]
reasonable justification for its choice of PM-10 as an indicator for
coarse particles, especially given that PM-10 includes not only coarse
particles but PM fine as well. 175 F. 3d at 1054-55.
Pursuant to the D.C. Circuit's decision, EPA deleted 40 CFR
50.6(d), the regulatory provision controlling the transition from the
pre-existing 1987 PM-10 standards to the 1997 PM-10 standards. 65 FR
80776. EPA proposed this deletion in the context of a proposed rule to
rescind a finding, made prior to the D.C. Circuit's vacatur of the 1997
standards, that the 1987 PM-10 standards no longer applied in Ada
County, Idaho. As EPA explained in the proposed rule, the Ada County
finding was based on the existence of the 1997 standards as well as the
transition policy. Because the court vacated those standards, leaving
in place the finding would have resulted in no federal protection from
high levels of coarse particulate matter pollution. Finding that result
untenable, EPA concluded that it was appropriate to restore the pre-
existing PM-10 standards with respect to Ada County. 65 FR at 39323. As
is clear from the final rule, however, the 1987 standards were never
revoked with respect to the rest of the country. Therefore, although
EPA deleted 40 CFR 50.6(d)(as required by the mandate of ATA I), the
pre-existing NAAQS continue to apply. 65 FR at 80777. If CCA believes
that insufficient notice was provided in connection with this final
action, it was required under CAA section 307(b)(1) to file a petition
for review of that action in the U.S. Court of Appeals within 60 days
of December 22, 2000. CCA did not do so and is therefore foreclosed
from raising this issue now.
Moreover, to the extent that CCA raises issues with respect to the
pre-existing 1987 PM-10 standards, we note that those standards were
upheld in Natural Resources Defense Council, Inc., et al. v. EPA, et
al., 902 F.2d 962 (D.C. Cir. 1990). In any case, the 1987 standards do
not use PM-10 as an indicator exclusively for coarse particles, but
rather are intended to address both PM-2.5 and PM-10-2.5, i.e. both
fine and coarse particles. 52 FR 24634, 24639 (July 1, 1987). Thus, any
concerns that PM-10 may be an inappropriate indicator for coarse
particles exclusively are inapplicable to the 1987 standard.
When CCA submitted its comment letter in 2004, EPA was in the
process of developing proposed regulations to again address thoracic
coarse particles. The Agency subsequently finalized such regulations in
2006. 71 FR 61144 (October 17, 2006). CCA's concerns regarding new
standards for PM-10, including putative confounding problems, were
properly raised in the context of that rulemaking. In fact, challenges
to the use of PM-10 as an indicator for coarse particles, as well as
challenges to the scientific bases for the 2006 final rule have been
raised by various petitioners in the pending D.C. Circuit cases
(American Farm Bureau Fed. et al. v. EPA and consolidated cases)
challenging the rule. CCA can, and is, pursuing its concerns in that
forum.
III. Final Action
EPA is finding that the Imperial area failed to attain the 24-hour
PM-10 NAAQS by the December 31, 2001 attainment deadline and is
requiring the State to submit under section 189(d) of the Act ``plan
revisions which provide for attainment of the PM-10 air quality
standards and, from the date of such submission until attainment, for
an annual reduction in PM-10 or PM-10 precursor emissions within the
area of not less than 5 percent of the amount of such emissions as
reported in the most recent inventory prepared for such area.'' The
plan must be submitted to EPA no later than one year from the
publication of this final rule.
The pollutant-specific requirements for moderate and serious PM-10
nonattainment areas are found in section 189 of the CAA, and the
general planning and control requirements for nonattainment plans are
found in CAA sections 110 and 172. In addition to the attainment
demonstration and 5 percent annual reductions requirements referenced
above, the PM-10 plan for the Imperial area must include the following
elements: \17\
---------------------------------------------------------------------------
\17\ For a brief discussion of these requirements, see our
proposed approval of the San Joaquin Valley PM-10 plan at 69 FR
5413, 5414 (February 4, 2004). See also the final rule at 69 FR
30006 (May 26, 2004).
---------------------------------------------------------------------------
Transportation conformity and motor vehicle emissions
budgets;
Emissions inventories;
Best available control measures for significant sources of
PM-10;
Reasonably available control measures for significant
sources of PM-10;
Control requirements applicable to major stationary
sources of PM-10 precursors pursuant to section 189(e); and
Reasonable further progress and quantitative milestones.
The District must also revise its new source review (NSR) rule to
reflect the serious area definitions for major new sources in CAA
section 189(b)(3) and must make any changes in its Title V operating
permits program necessary to reflect the change in the major source
threshold from 100 tpy for moderate areas to 70 tpy for serious areas.
Revisions to the NSR and Title V rules must also be submitted no later
than one year from the publication of this final rule.
IV. Statutory and Executive Order Reviews
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
final action is not a ``significant regulatory action'' and therefore
is not subject to review by the Office of Management and Budget. For
this reason, this action is also not subject to Executive Order 13211,
``Actions Concerning Regulations That Significantly Affect Energy
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action
merely makes a determination based on air quality data and does not
impose any additional requirements. Accordingly, the Administrator
certifies that this final rule will not have a significant economic
impact on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.). Because this rule does not
impose any additional enforceable duty, it does not contain any
unfunded mandate or significantly or uniquely affect small governments,
as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-
4). This rule also does not have tribal implications because it will
not have a substantial direct effect on one or more Indian tribes, on
the relationship between the Federal Government and Indian tribes, or
on the distribution of power and responsibilities between the Federal
Government and Indian tribes, as specified by Executive Order 13175 (65
FR 67249, November 9, 2000). This action also does not have Federalism
implications because it does not have substantial direct effects on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government, as specified in Executive Order 13132 (64
FR 43255, August 10, 1999).
This action merely makes a determination based on air quality data
and does not alter the relationship or the distribution of power and
responsibilities established in the CAA. Executive Order 12898
establishes a Federal policy for incorporating environmental justice
into Federal agency actions by directing agencies to identify and
address, as appropriate, disproportionately high and adverse
[[Page 70229]]
human health or environmental effects of their programs, policies, and
activities on minority and low-income populations. Today's action
involves determinations based on air quality considerations. It will
not have disproportionately high and adverse effects on any communities
in the area, including minority and low-income communities. This rule
also is not subject to Executive Order 13045 ``Protection of Children
from Environmental Health Risks and Safety Risks''(62 FR 19885, April
23, 1997), because it is not economically significant. 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. This rule does not
impose an information collection burden under the provisions of the
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
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 11, 2008. 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).)
