(May 5, 2004)
Before ANDERSON, CARNES and MARCUS, Circuit Judges.
ANDERSON, Circuit Judge:
I. INTRODUCTION
This case arises out of Sierra Club’s effort to block Oglethorpe Power
Corporation (“Oglethorpe”) from obtaining a permit for a portion of the Wansley
Steam-Electric Generating Plant (“Plant Wansley”), a power plant in Heard
County, Georgia. On November 30, 2000, Oglethorpe applied to the Georgia
Environmental Protection Division (“EPD”) for a permit for Block 8 of Plant
Wansley, the Wansley Combined Cycle Energy Facility (“Block 8”). EPD granted
the permit over Sierra Club’s objections on January 15, 2002. Sierra Club then
petitioned the Environmental Protection Agency (“EPA”) to object to EPD’s
decision under 42 U.S.C. § 7661d(b)(2). EPA declined to object. Sierra Club
appeals directly to this Court as provided in 42 U.S.C. § 7661d(b)(2) and 42 U.S.C.
§ 7607(b).
A. The Clean Air Act and the Georgia Rule
The Clean Air Act (“CAA”), 42 U.S.C. §§ 7401-7671q, requires EPA to
publish lists of emissions that “cause or contribute to air pollution which may
reasonably be anticipated to endanger public health or welfare, and to promulgate
primary and secondary national ambient air quality standards (NAAQS) for such
pollutants.” Alaska Dep’t of Envtl. Conservation v. EPA, 124 S. Ct. 983, 991
2
(2004) (citing 42 U.S.C. §§ 7408(a) and 7409(a)) (marks omitted). NAAQS
“define [the] levels of air quality that must be achieved to protect public health and
welfare.” Id. (citing R. Belden, Clean Air Act 6 (2001)). The CAA then gives the
tasks of implementing, maintaining, and enforcing NAAQS to individual states. Id.
States must develop, and seek EPA approval for, state implementation plans
(“SIPs”), which must “include enforceable emission limitations and other control
measures, means, or techniques . . . as may be necessary or appropriate to meet the
applicable [CAA] requirements.” Id. (citing 42 U.S.C. § 7410(a)(2)(A)).
Among other requirements, the CAA mandates that SIPs require permits for
the construction of new or modified “major stationary sources”1 located in
“nonattainment areas,” where the air fails to meet NAAQS. 42 U.S.C. § 7503. We
refer to this type of permit as a “preconstruction” permit. The CAA specifies that
no preconstruction permit may be issued unless
the owner or operator of the proposed new or modified source has
demonstrated that all major stationary sources owned or operated by
1
The “major stationary source,” a fundamental monitoring and compliance unit
under the CAA, is an aggregation of contiguous air pollution sources which collectively emit
certain levels of pollution. Title V of the CAA defines “major stationary source” as “any
stationary source (or any group of stationary sources located within a contiguous area and under
common control)” that (1) “emits or has the potential to emit considering controls, in the
aggregate, 10 tons per year or more of any hazardous air pollutant or 25 tons per year or more of
any combination of hazardous air pollutants” or (2) “emits, or has the potential to emit, one
hundred tons per year or more of any air pollutant.” 42 U.S.C. § 7661(2) (incorporating 42
U.S.C. § 7412(a)(1) (CAA § 112); 42 U.S.C. § 7602(j) (CAA § 302 or part D of Title I)).
3
such person (or by any entity controlling, controlled by, or under
common control with such person) in such State are subject to
emission limitations and are in compliance, or on a schedule for
compliance, with all applicable emission limitations and standards
under this Act[.]
42 U.S.C. § 7503(a)(3). Georgia has adopted the CAA’s language nearly verbatim.
See Ga. Comp. R. & Regs. r. 391-3-1-.03(8)(c)3 (hereinafter the “Georgia Rule” or
the “Rule”). The present dispute arises under this Georgia permit requirement.2
In addition to the preconstruction permit described above, Title V of the
CAA requires sources to have operating permits. 42 U.S.C. §§ 7661-61f; 40 C.F.R.
parts 70, 71.3 Title V imposes no new requirements on sources. Rather, it
consolidates existing air pollution requirements into a single document, the Title V
permit, to facilitate compliance monitoring. Sources subject to Title V may not
operate in violation of, or without, a Title V permit containing all applicable
requirements. 42 U.S.C. §§ 7661a(a); 40 C.F.R. §§ 70.7(b), 70.6(a)(1).4 SIP
2
Heard County, where Plant Wansley is located, is an attainment area. However,
the parties agree that Heard County sources must meet the requirements of Georgia Rule
391-3-1-.03(8)(c) because they contribute to the metropolitan Atlanta ozone nonattainment area.
Ga. Comp. R. & Regs. r. 391-3-1-.03(8)(e)1.
3
Part 70 applies to state-implemented Title V permit programs, and Part 71 applies
to Title V programs administered by EPA where there is no EPA-approved state program in
place.
4
The CAA requires permits to contain emissions limitations and a compliance
schedule, 42 U.S.C. § 7661c(a), monitoring procedures, § 7661c(b), and inspection, monitoring,
certification, and reporting requirements to assure compliance with the permit, § 7661c(c).
4
requirements are, of course, applicable requirements. Because the Georgia Rule is
part of Georgia’s SIP, Title V permits in Georgia are subject to the Georgia Rule’s
preconstruction permit requirement.
B. Sierra Club’s Challenge to Oglethorpe’s Permit
Plant Wansley, is an approximately 5,200-acre site located in Heard County,
Georgia, consisting of two 880-megawatt coal-fired units, one 50-megawatt oil-
fired combustion turbine, and ancillary equipment. On July 28, 2000, Georgia
Power, the owner of Plant Wansley, received a permit to build four new “power
blocks” for the plant, Blocks 6, 7, 8, and 9.5 Subsequently, Georgia Power decided
to transfer one as yet unbuilt power block, Block 8, to Oglethorpe, and another,
Block 9, to the Municipal Electric Authority of Georgia (“MEAG”). On November
30, 2000, Oglethorpe applied to EPD for a joint preconstruction and Title V permit
for Block 8. EPD has repeatedly noted that Blocks 6,7,8, and 9 operate under
common control and continue to comprise the same Title I and Title V site.6
5
EPD describes each “power block” as “One natural gas-fired only combined-cycle
block which will generate a total of approximately 521 megawatts (MWs) of electric power. The
combined-cycle block includes two combustion turbines, two supplementary fired heat recovery
steam generators and one steam turbine.” See, e.g., Part 70 Operating Permit, Wansley
Combined Cycle Energy Facility, Permit No. 4911-149-0006-V-01-0 (Jan. 15, 2002) at 1.
6
See Prevention of Significant Air Quality Deterioration Review of the Oglethorpe
Power Corporation Wansley Combined-Energy Facility, Power Block 8 (Preliminary
Determination) (Aug. 2001) at i (“The overall Wansley Electric Steam Generating Facility will
continue to be considered a common Title I and Title V facility between Georgia Power, OPC
[Oglethorpe Power Corporation], and MEAG.”); Part 70 Operating Permit (Draft), Wansley
5
Sierra Club argues that Oglethorpe is a part owner of noncompliant Plant
Scherer, and therefore Oglethorpe could not satisfy the Georgia Rule and EPA
should have objected to its permit.7 EPA rejected this argument. We conclude that
in reaching its conclusions, EPA failed to consider important aspects of the
problem, and thus acted arbitrarily and capriciously.8
II. DISCUSSION
As explained above, the Georgia Rule, in accordance with the CAA,
provides that EPD may not grant preconstruction permits for major stationary
sources to applicants that own or operate noncompliant major stationary sources.
Combined Cycle Energy Facility, Permit No. 4911-149-0006-V-01-0 (Sept. 14, 2001) at 1 (“The
Wansley Steam-Electric Generating Plant [Blocks 6 and 7], the Wansley Combined Cycle
Energy Facility [Block 8], and the Municipal Electric Authority of Georgia -Wansley Unit 9
[Block 9] comprise the same Title V site because the plants are located on contiguous property,
operate under common control, and have the same two digit SIC code.”); Part 70 Operating
Permit (Final), Wansley Combined Cycle Energy Facility, Permit No. 4911-149-0006-V-01-0
(Jan. 15, 2002) at 1 (“The Wansley Steam-Electric Generating Plant . . . the Wansley Combined
Cycle Energy Facility . . . and the Municipal Electric Authority of Georgia -Wansley Unit 9 . . .
comprise the same Title V site.”); Prevention of Significant Air Quality Deterioration Review of
the Oglethorpe Power Corporation Wansley Combined-Energy Facility, Power Block 8 (Final
Determination) (Jan. 2002) at 3 (specifically rejecting Oglethorpe’s contention that Block 8
should not be considered under “common control” between Oglethorpe and Georgia Power).
7
Oglethorpe argues as a threshold matter that it cannot be denied permits on the
basis of noncompliance by Plants Bowen or Scherer because although there are EPA enforcement
actions pending against each plant, neither has been finally adjudicated. We decline to address
this argument because the agency decision under review did not reach the question of whether the
Plant Scherer stationary source was not in compliance because the enforcement action had not
been fully adjudicated. On remand, Oglethorpe is of course free to present this argument to the
agency for its decision in the first instance.
8
We reject other arguments of the Sierra Club. See infra note 13.
6
Ga. Comp. R. & Regs. r. 391-3-1-.03(8)(c)3. The problem in this case is that
Oglethorpe owns part of a noncompliant major stationary source, i.e., Plant Sherer,
and the Rule is unclear regarding such situations. When the CAA or its
implementing regulations are ambiguous, we defer to the EPA’s reasonable
interpretation. Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc.,
467 U.S. 837, 842-43, 104 S. Ct. 2778, 2781-82 (1984). However, it would not be
appropriate to defer to EPA’s interpretation at this time because in reaching its
interpretation, EPA failed entirely to address or explain part of the problem it
faced. Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Auto. Ins. Co., 463 U.S. 29,
43, 103 S. Ct. 2856, 2866-67 (1983) (“Normally, an agency rule would be arbitrary
and capricious if the agency has relied on factors which Congress has not intended
it to consider, entirely failed to consider an important aspect of the problem,
offered an explanation for its decision that runs counter to the evidence before the
agency, or is so implausible that it could not be ascribed to a difference in view or
the product of agency expertise.”); Florida Power & Light Co. v. Lorion, 470 U.S.
729, 744, 105 S. Ct. 1598, 1607 (1985) (“If the record before the agency does not
support the agency action, if the agency has not considered all relevant factors, or if
the reviewing court simply cannot evaluate the challenged agency action on the
basis of the record before it, the proper course, except in rare circumstances, is to
7
remand to the agency for additional investigation or explanation.”). Without
considering the issue at all, the EPA Order implicitly assumed a positive answer to
the question of whether a major stationary source can be broken into parts with
compliance determined individually for purposes of the Georgia Rule. And
without explanation or acknowledgment, the agency gave a term two different
meanings in a single regulatory sentence. We do not defer in such a situation.
Sorenson v. Sec’y of Treasury, 475 U.S. 858, 860, 106 S. Ct. 1600, 1606 (1986)
(“[I]dentical words used in different parts of the same act are intended to have the
same meaning.”); see also New York v. Sullivan, 889 F.2d 401, 410 (2nd Cir.
1989) (stating that arbitrary and capricious review is “functionally equivalent” to
the Chevron reasonableness test), aff’d sub nom. Rust v. Sullivan, 500 U.S. 173,
111 S. Ct. 1759 (1991).9
9
We note that it is unclear whether Chevron deference applies to EPA’s
interpretation of the Georgia Rule because the Rule is a state regulation which EPA is not
specifically charged with administering and enforcing. The question of deference to federal
agency interpretations of state statutes or regulations has not been discussed extensively in the
courts. The Supreme Court has held that EPA’s interpretation of state environmental permitting
regulations is due deference “at least insofar as [the state regulations] affect the issuance of a
permit in another state.” Arkansas v. Oklahoma, 503 U.S. 91, 110, 112 S. Ct. 1046, 1059 (1992).
In Riverside Cement Co. v. Thomas, 843 F.2d 1246 (9th Cir. 1988), the Ninth Circuit, noting
that EPA’s enforcement role under the provision at issue there was “secondary,” determined that
“EPA may either accept or reject what the state proposes; but EPA may not take a portion of
what the state proposes and amend the proposal ad libitum.” Id. at 1248. In Montgomery Nat’l
Bank v. Clarke, 882 F.2d 87, 92 (3rd Cir. 1989), the Third Circuit deferred to the Comptroller of
the Currency’s interpretation of a state statute “that serves as [the] federal agency’s rule of
decision” where “the issue raised by the unsettled question of state law falls squarely within the
federal agency’s field of expertise and the state courts or state agency charged with administering
8
The first step in interpreting a text is, of course, to examine its language. See
United States v. Fisher, 289 F.3d 1329, 1337-38 (11th Cir. 2002). The Georgia
Rule states:
[N]o permit to construct a new or modified major stationary source [in
a nonattainment area] shall be issued unless . . . (3) The owner or
operator of the proposed new or modified source has demonstrated
that all major stationary sources owned or operated by such person (or
by an entity controlling, controlled by, or under common control with
such person) in this State, are subject to emission limitations and are in
compliance, or on a schedule for compliance, with all applicable
emission limitations and standards under the Act[.]
Ga. Comp. R. & Regs. r. 391-3-1-.03(8)(c)3. The plain reading of this provision is
that an owner or operator of a noncompliant major stationary source may not
receive a new Title V permit. The Rule is not clear, however, regarding how to
treat a partial owner of a noncompliant major stationary source. EPA read the Rule
as inapplicable to partial owners of noncompliant major stationary sources so long
the state statute have not ruled out the interpretation of the statute proffered by the federal
agency.” Id. at 92. Finally, the U.S. District Court for the Southern District of West Virginia
decided with reservation to defer to reasonable EPA interpretations of West Virginia water
regulations because of EPA’s knowledge and expertise in the area, Ohio Valley Envtl. Coalition
v. Horinko, 279 F. Supp. 2d 732, 754-56 (S.D.W.V. 2003), but determined that the particular
EPA interpretation it reviewed was unreasonable, id. at 756-57.
Although the Georgia Rule may not directly and immediately affect permitting in other
states, Arkansas v. Oklahoma, 503 U.S. at 110, 112 S. Ct. at 1059, we note that it does track the
language of the CAA, and we suspect that an interpretation of the Georgia Rule is sufficiently
intertwined with the administration of the CAA that it can be considered part of the federal law
of air pollution control. However, because we conclude below that we would owe no deference
in the present circumstances, we decline to determine whether the Chevron doctrine applies.

as the portions they own are compliant. EPA stated:
[T]he plain language of [the Georgia Rule] suggests that it aims to
ensure that an entity applying for a construction permit demonstrates
that all of its major sources in Georgia meet their compliance
obligations[.] . . . Oglethorpe Power is the “owner or operator” that
was obligated to demonstrate that all major stationary sources owned
or operated by Oglethorpe Power . . . in Georgia satisfy the rule’s
compliance obligations.
***
Oglethorpe Power has admitted it owns portions of only Units 1 and 2
at Plant Scherer. However, the EPA Notice of Violation cited by the
Petitioner alleges non-compliance only as to Plant Scherer’s Units 3
and 4. It is not clear from the plain language of [the Georgia Rule]
that it requires an owner or operator to make any demonstration as to
[noncompliant] facilities it does not own or operate, even if they are
located at the same plant site as facilities it does own or operate. . . .
Thus, with respect to Plant Scherer, EPA sees no reason to question
EPD’s determination that all of Oglethorpe Power’s facilities in
Georgia are in compliance with all applicable requirements.
Order Denying Petition for Objection to Permit at 6 (citations omitted) (emphasis
added).
Although the EPA Order did not explicitly acknowledge doing so, the
agency appears to have determined that the Georgia Rule allows breaking major
stationary sources into constituent parts with compliance determined individually.
But that interpretation requires giving the term “major stationary source” its
ordinary meaning in its first appearance in the Rule and redefining or ignoring it in
its second appearance in the very same sentence. This appears to be why EPA
10
shifted from speaking of “major stationary sources” to speaking of “facilities”
when explaining its interpretation. We emphasize and add subscript to the text of
the Georgia Rule to highlight EPA’s disparate uses of the term “major stationary
source”:
[N]o permit to construct a new or modified major stationary source1
[in a non-attainment area] shall be issued unless . . . (3) The owner or
operator of the proposed new or modified source has demonstrated
that all major stationary sources2 owned or operated by such person . .
. are subject to emission limitations and are in compliance, or on a
schedule for compliance, with all applicable emission limitations and
standards under the Act[.]
Ga. Comp. R. & Regs. r. 391-3-1-.03(8)(c)3 (emphasis added). Thus the EPA
Order seems to treat “major stationary source1” as an ordinary major stationary
source for Title V permitting purposes. But then, and without any explanation,
“major stationary source2” becomes EPA’s new term, “facilities.”
EPA’s interpretation is in tension with the language of the Georgia Rule.
The Rule and the CAA require owners or operators to demonstrate compliance of
their “major stationary sources” – not to demonstrate compliance of their
“facilities” or anything else. Because Congress used the term “major stationary
source” twice in the CAA, and the EPD reproduced it twice in the Georgia Rule,
the ordinary assumption would be that both Congress and the EPD intended the
term to appear twice rather than to be ignored or replaced in one instance. See
11
United States v. Steele, 147 F.3d 1316, 1318 (11th Cir. 1998) (“[W]e must presume
that Congress said what it meant and meant what it said.”). Moreover, the ordinary
interpretation of a term’s appearance twice in one sentence is that it has the same
meaning in each instance and is not intended to be ignored or replaced in either
instance. See Sorenson, 475 U.S. at 860, 106 S. Ct. at 1606 (“[I]dentical words
used in different parts of the same act are intended to have the same meaning.”);
TRW Inc. v. Andrews, 534 U.S. 19, 31, 122 S. Ct. 441, 449 (2001) (“It is a cardinal
principle of statutory construction that a statute ought, upon the whole, to be so
construed that, if it can be prevented, no clause, sentence, or word shall be
superfluous, void, or insignificant.”) (marks omitted). These principles of statutory
interpretation are not absolute, but EPA should offer something more before
abandoning them.
The EPA Order in this case provides no such justification. In the Order, the
EPA failed even to note that it has defined the same term, major stationary source,
in two different ways, and it failed to acknowledge, much less explain or justify,
the implicit policy decision driving the creation of the two definitions – that for
purposes of the Georgia Rule, “major stationary sources” may be broken into
separate parts with compliance determined individually. The Order simply noted
Sierra Club’s assertion that Plant Scherer is under the common control of
12
Oglethorpe and Georgia Power,10 and then summarily concluded that Oglethorpe
need not demonstrate that the major stationary source, i.e., Plant Scherer, was
compliant, because Oglethorpe owned only two of the four units at Plant Scherer
and because only the two units owned by Georgia Power are noncompliant.
However, given that the “major stationary source” is the unit Title V uses to
monitor compliance, it is unclear whether it is appropriate to determine the
compliance of part of a major stationary source. EPA’s Order ignored these
matters altogether. Because the EPA Order failed entirely to address or explain the
different meaning it placed upon the same term, and the related matters above
noted, it would not be appropriate to defer to the agency’s determination at this
time. State Farm, 463 U.S. at 43, 103 S. Ct. at 2866-67.
For the first time in its brief on appeal, EPA offers a post-hoc rationale for
the disparate treatment of the same term in its two appearances in the Georgia Rule.
EPA now suggests the term “major stationary sources” has in its first appearance its
established meaning in the permitting context, but that the same term has a
different meaning in its second appearance. EPA suggests that, for permitting
10
Because the EPA does not deny that Plant Scherer is under the common control
of Oglethorpe and Georgia Power, we assume the same arguendo, without the necessity of a
decision. Similarly, we assume arguendo that the Plant Scherer major stationary source is not in
compliance. See supra note 7.
13
purposes, emissions from multiple units or separate sources have to be aggregated
so that any group of stationary sources located within a contiguous area and under
common control are counted as a single “major stationary source.” EPA implicitly
acknowledges that the several units at Plant Scherer, including those of Georgia
Power and Oglethorpe, were under common control for permitting purposes.
However, EPA’s post-hoc reasoning is that the purpose of the statewide
compliance rule at issue in this case is entirely different, and is designed only “to
ensure that an entity that owns or operates one or more Title V sources that are not
currently in compliance . . . is not allowed to obtain a permit that authorizes the
construction of a new source until its existing sources are . . . compliant.” EPA
Brief at 24-25. On the other hand, it would seem that the Georgia Rule is speaking
of compliance of major stationary sources, not entities, because the Rule employs
the term “major stationary sources” and because that term, unlike “entities,” has an
established meaning for purposes of demonstrating compliance with the CAA and
its implementing regulations. However, because EPA’s rationale is offered only as
a litigation position in its brief on appeal, and was not articulated or explained by
EPA in its Order in this case, or in any rule or regulation brought to our attention,
we decline to address the merits of EPA’s new argument. Whether its rationale has
merit, and whether it follows that EPA should focus not on the major stationary
14
source itself but rather only on the part thereof owned by the applying entity, are
matters that should be addressed in the first instance by the agency possessing the
expertise and charged with the responsibility of administering this regulatory
program. Florida Power & Light Co., 470 U.S. at 744, 105 S. Ct. at 1607 (“If the
record before the agency does not support the agency action, if the agency has not
considered all relevant factors, or if the reviewing court simply cannot evaluate the
challenged agency action on the basis of the record before it, the proper course,
except in rare circumstances, is to remand to the agency for additional investigation
or explanation.”).
Also for the first time in its brief on appeal, EPA argues that a focus upon the
term “major stationary source,” as urged by the Sierra Club, would render
meaningless the subsequent inquiry prescribed under the Rule – “i.e., the inquiry
into whether those major stationary sources are ‘owned or operated by such person
(or by an entity controlling, controlled by, or under common control with such
person).’”11 EPA Brief at 25. Even in its brief, however, EPA does not explain
how the requirement of including controlling entities renders meaningless or even
11
The EPA Order did notice that the Georgia Rule suggests that it was aimed at
ensuring that an entity applying for a permit demonstrate that all of its major stationary sources in
Georgia meet their compliance obligations. However, the Order did not indicate that that
requirement, or the inclusion of controlling entities, was in any way inconsistent with the
separate requirement that it is the entity’s other “major stationary sources” which have to be in
compliance.
15
conflicts with, the fact that it is the “major stationary source” which has to be
compliant. In other words, the Rule would seem to embrace two separate but
consistent concepts: both the fact that it is an entity’s other “major stationary
sources” which have to be compliant; and the fact that the requirement extends also
to entities that control the original entity. In any event, this is again a post-hoc
rationalization offered for the first time as a litigation position in this case. Again,
we decline to address the merits.
Finally, EPA argues for the first time in its brief on appeal that the sole
purpose of the Georgia Rule at issue here (and necessarily the statutory provision
which the Rule tracks) is to provide an additional incentive for any applying entity
to bring all of its major stationary sources into compliance. EPA implies that the
incentive would not operate if the other, noncompliant major stationary source
were merely owned in part by the applying entity and the applying entity’s partial
ownership was not itself the cause of the noncompliance. Again we decline to
address this post-hoc rationalization; the existence vel non of influence that might
be exerted by a part-owner on its noncompliant joint venturer, and the significance
thereof, is a policy matter best addressed in the first instance by the agency.12
12
Finally, EPA’s interpretation of the Georgia Rule may have national implications.
As discussed above, the Georgia Rule tracks language in the CAA. See 42 U.S.C. § 7502(c); 42
U.S.C. § 7503(a). Therefore, if EPA applies its interpretation consistently in the future, then it
16
CONCLUSION13
would seem to have adopted a nationally applicable CAA interpretation. It is for the
Administrator of the EPA, not this Court, to judge whether EPA has made a determination of
nationwide scope. See 42 U.S.C. § 7607(b)(2). Of course, if the Administrator makes such a
finding in the future, then appeals of EPA’s action should be filed in the D.C. Circuit rather than
this regional Circuit. See id. We call attention to this issue because we note that the parties
failed to call it to our attention, and may also have failed to advise the agency; the Court noted
the issue at oral argument.
13
The Sierra Club argued before the agency that because Block 8 is part of the major
stationary source, Plant Wansley, and because this major stationary source is under the common
control of Georgia Power and Oglethorpe, then Georgia Power, as well as Oglethorpe, is an
“owner or operator of the proposed new or modified source.” Thus, the argument went,
Oglethorpe has to make a demonstration with respect to the compliance of other major stationary
sources owned by Georgia Power, as well as the demonstration with respect to Oglethorpe’s own.
See EPA Order at 5, 6-7, apparently addressing this argument, which it labeled as the Sierra
Club’s second argument. Similarly, in the summary of its argument in its brief on appeal, the
Sierra Club refers to this argument in one sentence: “In addition, EPA should have objected to
the Title V permit because the Wansley Combined Cycle Energy Facility is under the common
control of Oglethorpe and GPC.” Sierra Club Brief at 23. However, this argument is not
referred to again in the brief. Consequently, Oglethorpe in its brief argued that this theory has
been waived or abandoned. In its reply brief, the Sierra Club did not respond to Oglethorpe’s
waiver argument. Under such circumstances, we decline to address the argument. In light of the
fact that this matter is being remanded in any event to the agency, EPA may of course in its
discretion address the theory and expand upon its rather summary disposition in its previous
Order. That is, we assume, but do not decide, that the agency would have authority to excuse
such a waiver and address the merits of an issue, if, for example, the agency deemed that a
potential polluter was attempting to avoid regulation that the law intended by splitting up a
proposed major stationary source or by allotting ownership of a major stationary source to a
friendly but uncontrolled entity. Moreover, the issue of whether the statute and regulations
contemplate considering the owner or operator of the Plant Wansley major stationary source in
its entirety, on the one hand, or whether they contemplate considering only the owner or operator
of a part thereof, on the other hand, would seem to be the same or similar issue to that which the
agency will consider pursuant to our remand with respect to the Plant Scherer major stationary
source.
We reject without need for further discussion other arguments asserted by the Sierra
Club, including the argument that Georgia Power actually operates Oglethorpe’s Block 8 of Plant
Wansley because Georgia Power controls the water supply; with respect to the latter, we defer to
the decision reached in the EPA Order.
17
For the foregoing reasons, we conclude that the EPA Order failed to
acknowledge its disparate treatment of the same term in its two appearances in the
Rule, and thus failed entirely to address an important aspect of the problem.
Accordingly, the Order cannot survive the arbitrary and capricious standard of
review.
We grant the petition for review, vacate the EPA Order, and remand to the
agency for further consideration.
PETITION GRANTED; VACATED and REMANDED.
