Before BRORBY, GODBOLD * and McWILLIAMS, Circuit Judges.
BRORBY, Circuit Judge.
The Sierra Club and Wasatch Clean Air Coalition ("Petitioners") seek
judicial review of a final agency action in accordance with the Clean Air Act (the
"Act"), 42 U.S.C. § 7607(b)(1) (1994). Specifically, Petitioners challenge the
Environmental Protection Agency's decision to exempt Salt Lake and Davis
Counties, Utah (the "Counties") from selected Clean Air Act "nonattainment area"
requirements without first redesignating the Counties as an "attainment area"
pursuant to 42 U.S.C. § 7407(d)(3)(E)(i)-(v) (1994). Petitioners contend the
Environmental Protection Agency's decision is unreasonable and contrary to the
plain meaning of the Clean Air Act, and therefore must be set aside under both
the first and second steps of Chevron USA, Inc. v. Natural Resources Defense
Council, Inc., 467 U.S. 837 (1984).

Circuit, sitting by designation.

Having thoroughly reviewed the administrative record and considered the
parties' arguments, we uphold the Environmental Protection Agency's Clean Air
Act interpretation and deny the Petitioners' request to set aside the Environmental
Protection Agency's July 18, 1995 final decision entitled "Determination of
Attainment of Ozone Standard for Salt Lake and Davis Counties, Utah, and
Determination Regarding Applicability of Certain Reasonable Further Progress
and Attainment Demonstration Requirements."
NATURE OF THE CASE
The Clean Air Act, 42 U.S.C. §§ 7401 - 7671q (1994) establishes a
program, jointly administered by the federal government and the states, to
"protect and enhance the quality of the Nation's air resources so as to promote the
public health and welfare and productive capacity of its population." 42 U.S.C.
§ 7401(b)(1). Toward that end, the Act requires the Environmental Protection
Agency to establish primary and secondary National Ambient Air Quality
Standards for certain pollutants such as ozone. 1 Pursuant to the Act, areas failing
to meet the National Ambient Air Quality Standard for ozone are designated as
1
The National Ambient Air Quality Standard for ozone is 0.12 ppm not to
be exceeded more than 3 times in a three year period at any one monitoring
station. 40 C.F.R. § 50.9 & App. H (1995).
-3-
"nonattainment" areas, which must develop a State Implementation Plan with
sufficient control measures to attain and maintain the ozone standard. 42 U.S.C.
§ 7410.
In 1977, Salt Lake and Davis Counties, Utah, failed to meet the National
Ambient Air Quality Standards for ozone. Accordingly, the Counties were
designated as a nonattainment area and submitted a State Implementation Plan to
the Environmental Protection Agency. Amendments to the Clean Air Act in 1990,
which further classified ozone nonattainment areas according to the severity of air
pollution (e.g., marginal, moderate, serious, severe, and extreme), 42 U.S.C.
§ 7511, resulted in the Counties being reclassified as a "moderate nonattainment
area." 40 C.F.R. § 81.345 (1995). Moderate nonattainment areas are subject to
the requirement of 42 U.S.C. §§ 7511a(b)(1)(A)(i) and 7502(c)(9). Section
7511a(b)(1)(A)(i), 2 referred to as the "fifteen percent reasonable further progress
2
Section 7511a(b)(1)(A)(i) states in relevant part:
§ 7511a. Plan submissions and requirements
(b) Moderate Areas
(1) Plan provisions for reasonable further progress
(A) General rule
(i) By no later than 3 years after
November 15, 1990, the State shall submit a
revision to the applicable implementation
plan to provide for volatile organic
compound emission reductions, within 6
-4-
plan" and the "attainment demonstration" provision, requires moderate
nonattainment areas to continue "reasonable further progress" toward attaining
National Ambient Air Quality Standards. This goal is achieved by requiring the
area to submit a plan providing for a fifteen percent reduction in volatile organic
compounds. Additionally, § 7511a(b)(1)(A)(i) requires the submitted plan
provide for such specific annual emission reductions sufficient to demonstrate the
area will attain the National Ambient Air Quality Standards by the statutory
deadline. Section 7502(c)(9) provides further future compliance assurance by
requiring moderate and other nonattainment areas to submit a plan with specific
"contingency measures" to be implemented if the area fails to attain, or fails to
make reasonable further progress toward attaining, the National Ambient Air
Quality standards by the statutory deadline.
By the end of summer 1992 the Counties had collected the requisite three
years after November 15, 1990, of at least
15 percent from the baseline emissions,
accounting for any growth in emissions
after 1990. Such plan shall provide for
such specific annual reductions in emissions
of volatile organic compounds and oxides
of nitrogen as necessary to attain the
national primary ambient air quality
standard for ozone by the attainment date
....
-5-
years of ambient monitoring data to demonstrate attainment of the ozone standard.
In fact, the data demonstrates the Counties have attained the ozone standard since
1991. 3 Accordingly, in 1993, the State of Utah submitted an application to the
Environmental Protection Agency requesting that Salt Lake and Davis Counties
be redesignated as an "attainment" area pursuant to 42 U.S.C. § 7407(d)(3). The
Environmental Protection Agency and the State of Utah continue to work toward
the completion of the redesignation process.
Pending completion of the redesignation process, and based on air quality
data collected from 1992 to 1994, the Environmental Protection Agency issued a
direct final rule and a final rule, 4 which is the basis of Petitioners' challenge. 60
3
This improvement largely is attributed to the implementation of state air
quality plans in the 1980's that reduced motor vehicle emissions and applied
reasonably available control technology to the point sources of ozone precursor
pollutants. Ozone is formed through the interaction of volatile organic
compounds, nitrogen oxides, carbon monoxide and sunlight. The sources of these
ozone precursor pollutants include facilities that handle petroleum products,
combustion sources, petroleum fuel powered engines and biogenic sources.
4
A direct final rule becomes effective without further administrative
action, unless adverse comments are received within the time limit specified in
the proposed rule. If adverse comments are received, the Environmental
Protection Agency withdraws its direct final rule and issues a final rule that
addresses those comments. In this case, the Environmental Protection Agency
received comments from the Sierra Club and one other commenter. The
Environmental Protection Agency therefore withdrew its direct final rule and,
after considering the comments, issued its final rule.
-6-
Fed. Reg. 30,217 (1995) (proposed rule); 60 Fed. Reg. 30,189 (direct final rule).
In its final rule, without redesignating the area as an attainment area, the
Environmental Protection Agency determined that because the Counties had
attained the National Ambient Air Quality Standards the "fifteen percent
reasonable further progress plan" and the "attainment demonstration"
requirements of § 7511a(b)(1)(A)(i) and the "contingency measures" requirement
of § 7502(c)(9) were inapplicable. 60 Fed. Reg. at 36, 723. In addition, the State
of Utah would not be subject to Clean Air Act sanctions for failure to submit plan
revisions addressing these requirements. 5 Petitioners challenge this final rule,
asserting that the fifteen percent reasonable further progress plan, attainment
demonstration, and contingency measures requirements are mandatory absent
formal redesignation to attainment area status.
ANALYSIS
5
Any state failing to satisfy Clean Air Act requirements is subject to
federal sanctions in the form of stricter requirements for siting new or modified
pollution sources, or a prohibition on the approval of federal highway funds. 42
U.S.C. § 7509. The Environmental Protection Agency is authorized to impose
sanctions eighteen months after finding a state has failed to submit required State
Implementation Plan elements. This eighteen-month "sanctions clock" is turned
off if and when the deficiency is corrected, or when an area is redesignated to
attainment. See 42 U.S.C. §§ 7509(a), 7505a(c).
-7-
The issue for our determination is whether the Environmental Protection
Agency correctly determined that 42 U.S.C. §§ 7502(c)(9) and 7511a(b)(1)(A)(i),
do not apply to areas which are attaining the ozone standard, but which have not
yet been redesignated as attainment areas. This Court will set aside the
Environmental Protection Agency's determination only if it is arbitrary,
capricious, or otherwise not in accordance with law. 5 U.S.C. § 706(2)(A)
(1994). Where, as here, the issue turns on the Environmental Protection Agency's
interpretation of a statute it administers, our analysis is dictated by Chevron USA,
Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837 (1984). Applying
Chevron, we first determine whether the statute is unambiguous -- i.e., whether
Congress directly has spoken to the precise question at issue. Chevron, 467 U.S.
at 842-43; Marshall v. Chater, 75 F.3d 1421, 1428 (10th Cir. 1996). If
congressional intent is clear, we must give effect to that intent. If, however, the
statute is ambiguous or silent on the issue in question, we must proceed to the
second step of the Chevron analysis and determine whether the agency's
determination is based on a permissible construction of the statute. If the
agency's construction is reasonable, we will defer to the agency's interpretation.
Chevron, 467 U.S. at 842-44; Marshall, 75 F.3d at 1428.
A. Plain Language
-8-
Petitioners first contend the Environmental Protection Agency's final rule
exempting the Counties from the fifteen percent volatile organic compound
reduction, attainment demonstration and contingency measures requirements is
contrary to the plain meaning of the Clean Air Act and must be set aside under the
first step of the Chevron analysis. We disagree.
Petitioners' plain language argument is circuitous and difficult to
summarize. However, Petitioners appear to build from the premise that each of
the provisions at issue must be read individually and literally to give full effect to
any mandatory language included in those provisions. It is true a literal reading
of the first sentence of 42 U.S.C. § 7511a(b)(1)(A)(i), in isolation, does mandate
that a state with a moderate nonattainment area "shall submit a revision to the
applicable implementation plan to provide for volatile organic compound
emission reductions ... of at least 15 percent from baseline emissions." That
provision goes on, however, to state that "[s]uch plan shall provide for such
specific annual reductions in emissions of volatile organic compounds and oxides
of nitrogen as necessary to attain the national primary ambient air quality
standard for ozone." Id. (emphasis added). Moreover, the provision is captioned
"Plan provisions for reasonable further progress." The phrase "reasonable further
progress" is defined as "such annual incremental reductions in emissions of the
-9-
relevant air pollutant as are required by this part or may reasonably be required by
the Administrator for the purpose of ensuring attainment of the applicable
national ambient air quality standard." 6 42 U.S.C. § 7501(1) (emphasis added).
The plain language of 42 U.S.C. § 7502(c)(9) similarly refers to contingency
measures to be taken if an area "fails to make reasonable further progress, or to
attain the national primary ambient air quality standard." When read as a whole
to properly understand the statutory context, see Urban v. King, 43 F.3d 523, 526
(10th Cir. 1994), these two provisions fail to clearly require areas that have
attained the ozone standard but have not yet been redesignated to attainment
status to make further emission reductions. The language instead suggests
Congress intended the fifteen percent volatile organic compound reduction
requirement and the contingency measures requirement to apply only when
necessary to attain the relevant ozone standard.
At best, Petitioners' complex plain language argument establishes that some
ambiguity may exist as to Congress' intent . We therefore move on to consider
whether the Environmental Protection Agency's construction of the two provisions
at issue is a permissible one.
6
This definition applies for "the purposes of ... part" D of Title I of the
Clean Air Act, which includes 42 U.S.C. § 7511a(b)(1)(A)(i). Id.

B. The Environmental Protection Agency's Interpretation
Petitioners contend that even if the Environmental Protection Agency's
statutory interpretation does not violate the plain statutory language, the agency's
interpretation is unreasonable as it creates internal inconsistencies in the
Environmental Protection Agency's application of the Act and circumvents the
Clean Air Act 's preventive approach. The Environmental Protection Agency's
rationale for its determination is set forth fully in the final rule being challenged,
60 Fed. Reg. 36,723 (1995), and in the May 10, 1995 memorandum from John
Seitz, Director, Office of Air Quality Planning and Standards to the various
regional air quality directors. In essence, the Environmental Protection Agency
reasons that the purpose of the fifrteen percent volatile organic compound
reduction requirement, the attainment demonstration requirement and the
contingency measures requirement is to ensure reasonable further progress toward
and timely attainment of the National Ambient Air Quality Standard for ozone. If
an area can demonstrate via three years of monitoring data that it has in fact
attained the ozone standard, the purpose of those requirements has been fulfilled
and plan provisions outlining additional measures to achieve attainment would
have little meaning. Moreover, air quality controls designed to surpass the
applicable ozone standard would be both costly and unnecessary.
-11-
1. Programmatic Consistency.
Petitioners argue it is inconsistent for the Environmental Protection Agency
to apply some ozone nonattainment area requirements (e.g., the application of
reasonable available control technology to stationary sources and the
implementation of a motor vehicle inspection and maintenance plan), but not
others (e.g., the fifteen percent volatile organic compound reduction and
contingency measures). Instead, they would have the Environmental Protection
Agency rigidly apply all ozone nonattainment area requirements unless and until
an area is formally redesignated to attainment status. Petitioners contend there is
no basis for distinguishing the provisions since each requirement "has the same
substantive effect -- to reduce emissions of pollutants so that the [National
Ambient Air Quality Standard] is attained both now and in the future."
The Environmental Protection Agency consistently has rejected this all or
nothing approach. Shortly after the Clean Air Act Amendments of 1990, the
Environmental Protection Agency published a General Preamble for the
Implementation of Title I of the Clean Air Act Amendments of 1990. 57 Fed.
Reg. 13,498 (1992). In that preamble, the Environmental Protection Agency
determined certain general nonattainment plan requirements do not apply in
evaluating a request for redesignation to attainment under circumstances where
-12-
(1) an area has in fact monitored attainment of the standard, and (2) those
requirements are expressly linked by statutory language with the notion of
reasonable further progress. See 57 Fed. Reg. at 13,564. The Environmental
Protection Agency reasoned that when an area requests redesignation to
attainment status,
at a minimum, the air quality data for the area must show that the
area has already attained [the National Ambient Air Quality
Standards]. Showing that the State will make [reasonable further
progress] towards attainment will, therefore, have no meaning at that
point.
57 Fed. Reg. at 13,564. In other words, once the standards are obtained,
requirements related to the demonstration of reasonable further progress toward
attainment serve no purpose. Any additional or future air quality protection is left
to the operation of other Clean Air Act provisions.
The determination to exempt Salt Lake and Davis Counties from analogous
ozone-specific nonattainment plan requirements is a logical extension of the
Environmental Protection Agency's original, general interpretation of the 1990
Clean Air Act Amendments. We afford deference to the Agency's interpretation
under these circumstances. New Mexico Envtl. Improvement Div. v. Thomas, 789
F.2d 825, 831-32 (10th Cir. 1986) (the court will defer to an agency's statutory
interpretation when such an interpretation is contemporaneous with the
-13-
legislation's enactment and has been consistently adhered to by the agency over
time).
Consistent with its interpretation of the general reasonable further progress
provisions, the Environmental Protection Agency exempted the Counties from the
§§ 7511a(b)(1)(A)(i) and 7502(c)(9) requirements because the statutory language
imposing those requirements is directly linked to the notion of reasonable further
progress toward attainment. Here again, the stated purpose of "reasonable further
progress" is to ensure attainment by the applicable attainment date. If a moderate
ozone nonattainment area has in fact already attained the ozone standard, it would
make little sense to require a state to demonstrate the area will make reasonable
progress toward attainment.
Not all ozone nonattainment area provisions are semantically connected to
reasonable further progress requirements. For obvious reasons, the application of
those provisions (i.e., the application of reasonable available control technology
to stationary sources and the implementation of a motor vehicle inspection and
maintenance plan, 42 U.S.C. §§ 7511a(b)(2), 7511a(b)(4)) continues to fulfill
important Clean Air Act objectives whether or not an area has attained the ozone
standard. Accordingly, the Environmental Protection Agency affords no relief
-14-
from those requirements based on actual attainment.
We do not find the Environmental Protection Agency's interpretation to
create programmatic inconsistency. Nor do we find anything in the structure or
language of the nonattainment area provisions at issue that contradicts the
Environmental Protection Agency's longstanding interpretation. In sum, the
Petitioners' uncompromising reading of the ozone nonattainment area
requirements lacks the textual support necessary to overcome the Environmental
Protection Agency's pragmatic construction.
2. The Redesignation Process.
Petitioners assert that the redesignation process outlined at 42 U.S.C.
§ 7407d(3)(E) represents the exclusive means by which an area may be
redesignated from nonattainment to attainment status. Thus, Petitioners argue,
the Environmental Protection Agency is not authorized to make any factual
determination of attainment outside the formal redesignation process.
The Environmental Protection Agency may redesignate an area from
nonattainment to attainment in accordance with the provisions of 42 U.S.C.
§ 7407(d)(3)(E). Notably, this process involves more than a simple determination
-15-
the area has attained the relevant National Ambient Air Quality Standards. In
addition to that factual determination, the Environmental Protection Agency must
(1) fully approve the State Implementation Plan; (2) determine that the
improvement in air quality is due to permanent and enforceable reductions in
emissions resulting from implementation of the State Implementation Plan and
other required reductions; (3) fully approve a maintenance plan under 42 U.S.C.
§ 7505a; and (4) determine that the State has met all applicable requirements
under 42 U.S.C. § 7410 with respect to State Implementation Plans generally, and
under part D with respect to State Implementation Plan provisions for
nonattainment areas. 42 U.S.C. § 7407(d)(3)(E). Before an area may be
redesignated to attainment, the State also must adopt and submit maintenance
plans that (1) provide for maintenance of the National Ambient Air Quality
Standards for at least ten years after redesignation, and (2) include additional
measures as necessary to ensure the area remains in attainment. 42 U.S.C.
§ 7505a. The State further is required to revise its maintenance plan eight years
after redesignation to cover a second ten-year period after the first ten-year
maintenance plan expires. 7 42 U.S.C. § 7505a(b).
7
Accordingly, the Environmental Protection Agency intends that the
maintenance plans will ensure that population growth and other changes in a
redesignated area over a twenty-year period do not lead to a violation of the
relevant National Ambient Air Quality Standards.
-16-
The Environmental Protection Agency has made it abundantly clear its
determination to exempt the Counties from certain reasonable further progress
and attainment demonstration requirements is not a de facto redesignation to
attainment status. 60 Fed. Reg. at 36,723. As discussed above, the redesignation
process involves more than a factual determination that monitoring data
establishes attainment with the applicable standard. All redesignation criteria at
42 U.S.C. § 7407(d)(3)(E) remain in full force and effect and must be satisfied
before the Environmental Protection Agency will approve the Counties' pending
redesignation request. Moreover, if the Counties violate the ozone National
Ambient Air Quality Standards prior to their redesignation to attainment status,
the exemption from certain attainment demonstration and reasonable further
progress requirements will no longer apply, and the Counties will have to submit
plan revisions pursuant to 42 U.S.C. §§ 7502(c)(9) and 7511a(b)(1)(A)(i). In
addition, if the Counties violate the ozone standards prior to redesignation, they
would be "bumped-up" from moderate nonattainment status to serious
nonattainment status pursuant to 42 U.S.C. § 7511(b)(2), and would then have to
satisfy the more stringent requirements imposed on serious ozone nonattainment
areas. See 42 U.S.C. § 7511a(c)(2)(b). Under these circumstances, the
Petitioners' argument that the Environmental Protection Agency is somehow
circumventing the formal redesignation process is unavailing. The Environmental
-17-
Protection Agency has convincingly demonstrated it is not circumventing the
redesignation process and the State of Utah is not without incentive to complete
this process.
3. Statutory Purpose.
Finally, Petitioners argue the Environmental Protection Agency's Clean Air
Act interpretation is unreasonable as it fails to satisfy the Clean Air Act's purpose
to protect public health. In this context, the Petitioners emphasize their concern
that the Environmental Protection Agency is failing to ensure the Counties will
continue to attain the applicable ozone standards in the future by creating a
"limbo" between attainment and nonattainment status "that deprives citizens of
the contingent protections against future declines in air quality."
We remain unpersuaded by this argument. As discussed above, the
provisions at issue are directly linked to reasonable further progress toward
attainment of the ozone National Ambient Air Quality Standards, not beyond. To
date, the Utah State Implementation Plan's existing air quality control measures
and other applicable federal requirements (e.g., the motor vehicle control
program) have resulted in enforceable emission reductions within the Counties --
reductions which in turn have resulted in attainment of the ozone standard for
-18-
over five years. Should those existing control measures and requirements prove
inadequate to prevent future violations, the Environmental Protection Agency will
require the Counties to implement additional control measures within a reasonable
time. Recall that the Environmental Protection Agency's determination to exempt
the Counties from limited ozone nonattainment area requirements is really no
more than a suspension of those requirements for so long as the area continues to
attain the standard or until the area is formally redesignated to attainment status.
The Environmental Protection Agency summarized the flaw in Petitioners'
argument best:
The [Counties have] attained the primary ozone standard, a standard
designed to protect public health with an adequate margin of safety
(see section 109(b)(1)). [The Environmental Protection Agency 's]
action does not relax any of the requirements that have led to the
attainment of the standard. Rather, its action has the effect of
suspending requirements, for additional pollution reductions, above
and beyond those that have resulted in the attainment of the health-
based standard.
60 Fed. Reg. at 36,727. Under these circumstances, Petitioners' presumption that
the Counties will violate ozone standards in the future and that "Utahns will be
required to breathe for a protracted period unhealthy air while Utah develops
controls that should have been in place earlier" seems disingenuous.
CONCLUSION
-19-
We conclude the Environmental Protection Agency has reasonably
interpreted and applied the Clean Air Act to preserve the Act's objective of
achieving the health-based ozone standard while at the same time avoiding the
imposition of costly emission control requirements that are unnecessary to meet
that objective. Accordingly, we uphold the Environmental Protection Agency's
"Determination of Attainment of Ozone Standard for Salt Lake and Davis
Counties, Utah, and Determination Regarding Applicability of Certain Reasonable
Further Progress and Attainment Demonstration Requirements" and deny the
Petition for Review.
