ENVIRONMENTAL PROTECTION AGENCY, ET AL.

ON PETITION FOR A WRIT OF CERTIORARI TO THE
UNITED STATES COURT OF APPEALS
FOR THE SIXTH CIRCUIT

BRIEF FOR THE FEDERAL RESPONDENTS
IN OPPOSITION

OPINION BELOW

The opinion of the court of appeals (Pet. App.
1-12) is reported at 523 F. 2d 16.

JURISDICTION

The judgment of the court of appeals was en-
tered on September 4, 1975. The petition for a writ

(1)

2

of certiorari was filed on December 2, 1975. This
Court’s jurisdiction is invoked under 28 U.S.C. 1254

(1).
QUESTIONS PRESENTED

1. Whether this case is moot.

2. Whether the Administrator of the Environ-
mental Protection Agency correctly interpreted Sec-
tion 110(a)(2)(B) of the Clean Air Act, as added,
42 U.S.C. 1857c-5(a) (2) (B), to require that state
implementation plans, designed to meet national am-
bient air quality standards, must use continuous
emission reduction measures to the extent available
rather than intermittent emission control measures.

STATUTE INVOLVED

Section 110 of the Clean Air Act, as added by the
Clean Air Amendments of 1970, 84 Stat. 1680, 42
U.S.C. 1857c-5, is set out in pertinent part at Pet.

3-4.
STATEMENT

1. The Clean Air Act, 77 Stat. 392, as amended,
42 U.S.C. 1857, et seq., requires the Administrator
of the Environmental Protection Agency (the Ad-
ministrator) to promulgate national primary and
secondary ambient air quality standards that will
protect the public from known or anticipated adverse
effects of various air pollutants. Each State has the
primary responsibility for assuring the quality of
the air within its territory and must devise a state
implementation plan (SIP) designed to, at a mini-

es

3

mum, implement, maintain and enforce the national
primary and secondary ambient air quality stand-
ards.

Under Section 110(a)(2) of the Act, 42 U.S.C.
1857c-5(a) (2), the Administrator is required to ap-
prove the state implementation plan if he determines, .
inter alia, that “it includes emission limitations,
schedules, and timetables for compliance with such
limitations * * *.” (Section 110(a)(2)(B), 42
U.S.C. 1857c-5(a) (2) (B)).

2. In December 1973, Kentucky submitted its
state implementation plan, which contained the fol-
lowing provision Section 1(1)(b)):

Where it is demonstrated to the satisfaction of
the Commission that an air contaminant source
can apply an alternate control strategy which
will provide for achievement and maintenance
of applicable ambient air quality standards, the
Commission may, under such terms and condi-
tions as it deems appropriate, authorize such a
control strategy after a public hearing.

On August 9, 1974, the Administrator approved
the Kentucky implementation plan, except with re-
spect to Section 1(1)(b). He based his refusal to ap-
prove this part of the plan on the ground that Sec-
tion 1(1)(b) “could be construed to permit intermit-
tent control measures under circumstances where con-
stant emission controls were available.” 39 Fed.
Reg. 29358.’

* Switching to cleaner fuels or curtailing plant operations
when air quality declines are examples of intermittent control

4

Thereafter, petitioner and certain private power
companies filed timely petitions for review of the
Administrator’s action in the United States Court
of Appeals for the Sixth Circuit. The cases were
consolidated. The Commonwealth of Kentucky,
among others, intervened as a respondent.

3. On July 2, 1975, Kentucky adopted a new
state implementation plan, retroactively taking ef-
fect on June 6, 1975, which deleted Section 1(1) (b).
In its brief before the court of appeals Kentucky
stated that (Br. for Commonwealth of Kentucky,
p. 12):

The air pollution control agency of this Com-
monwealth has indicated by its proposed regu-

measures; average long term emissions are not necessarily
reduced as a result of such measures. As stated in the fol-
lowing EPA staff paper (119 Cong. Rec. 19190 (1973)):

Depending on the circumstances, [an intermittent con-
trol system] may or may not reduce the average long-
term emissions. If plant operation is curtailed during
poor dispersion conditions, then it may be increased dur-
ing good conditions to make up for the lost production.
Average emissions would be about the same with or
without [an intermittent control system] for this situa-
tion. If clean fuel is used to reduce emissions during
poor dispersion conditions, then average emissions will
be reduced somewhat. If fuel with higher sulfur content
is used during good conditions, then average emissions
could be greater with [an intermittent control system].
It must be concluded, therefore that although [an inter-
mittent control system] employs temporary emission limi-
tation, the long-range control method is that of taking
advantage of good dispersion rather than emission re-
duction.

5

lations that it does not desire to administer the
provisions of the regulation involved [Section
1(1)(b)] and does not wish to have such a regu-
lation included in the “Kentucky Plan.” * * *
[Alternate control strategies are not to play a
part in this Commonwealth’s implementation of
the Clean Air Act irrespective of the decision of
this Court with regard to the Environmental
Protection Agency Administrator’s action.

Accordingly, Kentucky and the federal respondents
moved to dismiss the case as moot.

4. On September 4, 1975, the court of appeal:
denied the motions to dismiss and denied the peti-
tions for review (Pet. App. 1-12). The court held
that the case was not moot because the Administra-
tor’s action in refusing to approve Section 1(1) (b)
“is clearly capable of repetition, but * * * would
evade review if the principle of mootness were strictly
applied” (Pet. App. 6), and because “[t]he public
[has an] interest in determination of the question
in this case” (ibid.).

On the merits, the court held that the Adminis-
trator was not required to approve the original Ken-
tucky plan because it did not include an “emission
limitation” as required by Section 110(a)(2)(B) of
the Clean Air Act, as added, 42 U.S.C. 1857c-5(a)
(2)(B). The court relied upon Train v. Natural
Resources Defense Council, 421 U.S. 60, 78, in which
this Court stated that “ ‘emission limitations’ * * *
are regulations of the composition of substances

6

emitted into the ambient air * * *.” The court con-
cluded that the Administrator acted within the scope
of his authority in refusing to approve that portion
of the Kentucky plan “which might be construed to
permit a source of pollutant emissions to continue
operating * * * without the application of one or
more systems which control the ‘kind and amounts’
of its air contaminant emissions” (Pet. App. 11).

ARGUMENT

1. Although we submit that the decision of the
court of appeals on the merits is correct, we never-
theless disagree with the court’s preliminary hold-
ing that the case is not moot. As we indicated above,
Kentucky’s current air pollution regulations do not
contain Section 1(1)(b) and Kentucky “does not de-
sire to administer the provisions of the regulation in-
volved [Section 1(1)(b)] and does not wish to have
such a regulation included in the ‘Kentucky Plan’ ”.’
Moreover, Kentucky has stated that “it appears that
alternate control strategies are not to play a part
in this Commonwealth’s implementation of the Clean
Air Act irrespective of the decision of this Court
with regard to the Environmental Protection Agency
Administrator’s action” (ibid.). The case is therefore

moot. See Securities and Exchange Commission v.
Medical Committee for Human Rights, 404 U.S. 403.

Contrary to the court of appeals, the case cannot
be considered a live controversy on the basis that
the order involved is “capable of repetition, yet evad-
iug review,” Southern Pacific Terminal Co. v. Inter-
state Commerce Commission, 219 U.S. 498, 515. The
Administrator’s disapproval of Section 1(1)(b) of
the Kentucky plan is not “capable of repetition” so
far as Kentucky is concerned, since Kentucky has de-
cided that it does not wish to have Section 1(1) (b)
included in its implementation plan and does not wish
to use alternative control strategies irrespective of
whether the Administrator is required to approve
them.’

Moreover, there is no reason to suppose that the
issue will in the future evade review. The Admin-
istrator’s disapprovals of state plans are not “short
term orders,” Southern Pacific Terminal Co. v. In-
terstate Commerce Commission, supra, that expire
before judicial review can occur. If a State wishes
to contest the Administrator’s interpretation, it need
only promulgate an implementation plan permitting

* The “public interest in having the legality of the prac-
tices settled,” United States v. W. T. Grant Co., 345 U.S. 629,
633, is not in itself sufficient to overcome mootness. See
DeFunis Vv. Odegaard, 416 U.S. 312. While the Court has
held that a case may not be moot if the allegedly illegal con-
duct is likely to recur (345 U.S. at 632), in this case no such
likelihood exists since the State will not seek to reinstitute
intermittent controls. See United States v. Phosphate Export
Assn., 393 U.S. 199, 203.

intermittent controls without a prior showing that
a continuous limitation on emissions is unavailable.*
This case therefore does not present the exceptional
situation in which the Southern Pacific Terminal
doctrine might permit a departure from “[t]he
usual rule in federal cases * * * that an actual con-
troversy must exist at stages of appellate or certio-
rari review, and not simply at the date the action
is initiated.”” Roe v. Wade, 410 U.S. 113, 125; United
States v. Munsingwear, 340 U.S. 36; DeFunis v. Ode-
gaard, 416 U.S. 312, 319.

2. In any event, the decision of the court of ap-
peals on the merits is correct and does not conflict
with any decision of this Court or any court of
appeals.°

*In fact, the legality of the Administrator’s actions in this
regard has been tested and settled in two other circuits. See
Natural Resources Defense Council, Inc. V. Environmental
Protection Agency, 489 F.2d 390, 406-409 (C.A. 5), reversed
in part on other grounds sub nom. Train v. Natural Resources
Defense Council, 421 U.S. 60; State of Texas v. Environ-
mental Protection Agency, 499 F.2d 289, 311-313 (C.A. 5);
Kennecott Copper Corporation v. Train, C.A. 9, No. 75-1335,
decided November 28, 1975, petition for a writ of certiorari
pending, No. 75-1029.

5In Union Electric Company V. Environmental Protection
Agency (No. 74-1542), argued January 21, 1976, we con-
tended that upon judicial review of the Administrator’s ap-
proval of a state implementation plan under the Clean Air
Act, the court may not consider claims that compliance is
economically or technologically infeasible. As we argued in
that case, there is no requirement in Section 110(a) (2) of
the Act, 42 U.S.C. 1857c-5(a) (2), that in deciding whether
to approve a state-submitted implementation plan the Admin-

9

a. Section 110(a)(2)(B) of the Clean Air Act,
as added, 42 U.S.C. 1857c-5(a) (2) (B), requires that
every state implementation plan include

emission limitations, schedules, and timetables
for compliance with such limitations, and such
other measures as may be necessary to insure
attainment and maintenance of such primary
or secondary standard, including, but not lim-
ited to, land-use and transportation controls.

Every court that has considered this language has
construed it to require the use of all available meas-
ures for continuous limitation of emissions. See cases
cited, note 4, supra.

In Train v. National Resources Defense Council,
supra, 421 U.S. at 78, this Court stated that state
implementation plans to attain and maintain na-
tional ambient air standards

must include “emission limitations,” which are
regulations of the composition of substances
emitted into the ambient air from such sources
as power plants, service stations, and the like.

istrator must consider whether compliance with the emission
limitations therein is feasible. Accordingly, so long as the plan
is sufficient to achieve ambient air standards and requires
continuous emission limitations, it must be approved.

If a state plan can be construed to permit intermittent
emission limitations, however, the Administrator must review
it to determine whether the intermittent controls are justified.
Only if the demonstration of adequacy which must accompany
the submission of each implementation plan shows that con-
stant emission controls are unavailable will the Administrator
approve a plan that permits dispersion technology such as
intermittent controls.

10

They are specific rules to which operators of
pollution sources are subject, and which if en-
forced should result in ambient air which meets
the national standards [emphasis supplied ].°

The court below correctly interpreted this to mean
that “emission limitations” do not include regula-
tions that merely regulate the time during which
pollutants may be dispersed into the atmosphere,
which is the effect of intermittent controls.

b. The purpose of the Clean Air Act further con-
firms that Congress intended to require that state
implementation plans require continuous emission
controls if available. National primary ambient air
quality standards are those “requisite to protect the
public health,” 42 U.S.C. 1857c-4\0)(1); nationsi
secondary ambient air quality standards are those
“requisite to protect the public welfare from any
known or anticipated adverse effects associated with

* To be sure, the Court in Train held that “so long as the
national standards are being attained and maintained, there
is no basis in the present Clean Air Act for forcing further
technological developments” (id. at 91). But the Court was
referring to modification of source-by-source emission limi-
tations fixed by the State, which the Administrator must
approve so long as the state plan as a whole provides for a
mix of emission limitations from all sources sufficient to meet
national air quality standards; if these limitations are suffi-
cient, the Administrator may not raise the limitation on a
particular source to force technological improvement as to
that source. The Court did not thereby preclude the Adminis-
trator from withholding his approval of state implementation
plans that did not employ “emission limitations” because they
could be construed to permit intermittent emission controls
when continuous controls were available.

11

the presence of such air pollutant in the ambient
air,” 42 U.S.C. 1857c-4(b)(2). State implementa-
tion plans must provide for attainment and “main-
tenance” of these standards, 42 U.S.C. 1857c-5(a)
(1). Intermittent controls, however, do not provide
a sufficient guarantee that national primary and
secondary ambient air quality standards will be
maintained.

As the court of appeals stated in Kennecott Cop-
per Corporation v. Train, supra, slip op. 10:

Intermittent control systems (such as those re-
stricting production, or utilizing less polluting
fuels, during periods of adverse weather) do
limit the amount of pollutant emitted while such
controls are being applied. However, the reli-
ability and enforceability of such controls is
questionable; they may not be implemented when
they are in fact needed. Moreover, there is no
assurance that temporary reductions in emis-
sions resulting from such controls will not be
balanced, or even exceeded, by an increase in
the amount of pollutant emitted when weather
conditions improve and production is increased
to make up for prior losses, or more polluting
fuels are again used. Thus, intermittent con-
trols, like tall stacks, may only disperse the pol-
lutant rather than reduce it. Tall smokestacks
disperse a pollutant through greater quantities
of air; intermittent control systems disperse a
pollutant through longer periods of time. Nei-
ther assures a reduction in the quantity of the
pollutant eventually emitted. Under section
[110(a)(2)(B)], EPA may require that assur-
ance. [Footnote omitted. ]

12

Moreover, the use of intermittent controls that
merely regulate the timing of dispersion of pollu-
tants into the atmosphere is at odds with the policy
of non-degradation in the Clean Air Act.’ As the
court of appeals stated in Natural Resources Defense
Council, Inc. v. Environmental Protection Agency,
supra, 489 F. 2d at 408-409:

Dispersion * * * techniques operate by keeping
pollutants out of areas of high pollutant con-
centration, and dispersing them to lower con-
centration areas; their objective is to reduce
concentrations in high-concentration areas. In-
evitably, however, the pollutants emitted into
the atmosphere must end up somewhere; and the
atmosphere at their destination, wherever that
may be, will be degraded, in violation of the con-
gressional policy. The only techniques fully
capable of guaranteeing non-degradation are
[continuous] emission limitation techniques.*

ce. “[{S]ubsequent legislation declaring the intent of
an earlier statute is entitled to significant weight,”
National Labor Relations Board v. Bell Aerospace

* This policy requires that areas of clean air, where air
quality indices are above the levels set by the national stand-
ards, must not be degraded, even though degradation will
not reduce the quality of the air below levels specified by the
standards. See S. Rep. No. 91-1196, 91st Cong., 2d Sess.
2 (1970); H.R. Rep. No. 91-1146, 91st Cong., 2d Sess. 1, 2,
5 (1970); Sierra Club v. Ruckelshaus, 344 F. Supp. 253, 255
(D.D.C.), affirmed sub nom. Fri v. Sierra Club, 412 U.S. 541.

* The court classified both tall stacks and intermittent con-
trols as dispersion techniques (489 F.2d at 394 n.2).

13 ——

Company, 416 U.S. 267, 275,° and the legislative his-
tory of subsequent amendments to the Clean Air

* In its petition (at pp. 18-23), TVA contends that a num-
ber of statements by former Administrator Ruckelshaus show
that he interpreted Section 110(a) (2) of the Clean Air Act
to permit intermittent emission controls instead of continu-
ous emission controls. In the statements to which TVA
refers, however, Administrator Ruckelshaus merely restates
the general congressional policy, reflected in the Act, to re-
quire the Administrator to approve state plans that meet the
ambient air quality standards and not to dictate to the state
precisely what techniques should be used to maintain those
standards. Accordingly, he construed the term “emission limi-
tations” to include a variety of measures, such as restriction
on the hours and manner of operations. (Hearings on Im-
plementation of the Clean Air Act Amendments of 1970—
Part 1 (Title I) before the Subcommittee on Air and Water
Pollution of the Senate Committee on Public Works, 92d
Cong., 2d Sess. 314-315 (1972).)

Administrator Ruckelshaus did not construe the Act, how-
ever, to permit the approval of state implementation plans
that would not reasonably guarantee the maintenance of the
ambient air quality standards, or that would not assure a
reduction in the quality of the pollutant eventually emitted;
to the contrary, he assumed throughout that plans would be
approved only if they included measures that were sufficient
for attaining and maintaining such standards. In fact, at an
earlier point in the hearings he stated, “whenever we adopt
a control strategy, the purpose of that control strategy is to
reduce emission * * *. What we mean by emission limitations
is really emission reduction * * *” (Hearings, supra, at 265).
Intermittent control measures are not satisfactory “emission
limitations”, however, since they do not guarantee the main-
tenance of the ambient air quality standards or assure a re-
duction in the quantity of pollutants eventually ernitted (see
pp. 11-12, supra). Accordingly, the statements of Adminis-
trator Ruckelshaus should not be construed to permit inter-
mittent emission controls when continuous emission controls
are available.

14

Act shows that Congress intended that state imple-
mentation plans should require the use of continuous
emission controls when available.

Congress amended the Clean Air Act in 1974, in
response to the 1973 oil embargo and resulting en-
ergy crisis. As it passed the House, the 1973 prede-
cessor to the 1974 amendment, which subsequently
was vetoed, permitted the permanent use of inter-
mittent controls at certain emission sources.” The
Conference Committee eliminated this provision and
in its draft permitted intermittent controls only by
pollution sources that converted to coal and then
only as a temporary relief measure under specified
conditions."

In March 1974, the Administrator transmitted a
new proposed bill to the House which, in pertinent
part, was the same in substance as the statute even-
tually adopted. The Administrator also transmitted
another proposal, which he did not support, that
would have amended Section 1857c-5(a)(2)(B) to
provide that nothing in that section was to be con-
strued “ ‘to preclude use of * * * intermittent control
measures.’”’** The Administrator stated that this

proposed amendment, which was intended “ ‘to
allow the use of intermittent control strategies as a
permanent method for achieving compliance with
stationary source emission standards,’ ” would “ ‘sig-
nificantly weaken the Clean Air Act.’” The Admin-
istrator then reaffirmed the contrary position taken
by the Environmental Protection Agency, stating,
“*lajs in the past, EPA will contend that the in-
termittent controls can be used only as an expedient,
temporary control measure.’ ” *

In the course of presenting to the Senate the Con-
ference Report on the 1974 amendment, Senator
Muskie, Chairman of the Subcommittee on Air and
Water Pollution and manager of the bill in the Sen-
ate, stated (120 Cong. Rec. S 10409 (daily ed., June
12, 1974)):

* * * [N]o one should view limited application
of enforceable strategies related to this legisla-
tion as a precedent for future legislation or as
a reinterpretation of the requirements of the
existing law which bar the application of in-
termittent control strategies as a substitute for
emission limitations.

When finally enacted, the Energy Supply and En-
vironmental Coordination Act of 1974, Pub. L. 93-
319, 88 Stat. 246, added a new Section 119 to the
Clean Air Act, 42 U.S.C. (Supp. IV) 1857c-10,
which permits certain power plants and other large
emission sources that convert from burning oil or

natural gas to burning coal to obtain temporary re-
lief from air pollution control requirements and
thereby to use intermittent controls temporarily if
certain specified conditions are met. One of the con-
ditions is that the source in question must enter into
binding contracts to acquire either a long-term sup-
ply of low-sulphur coal or a “continuous emission
reduction system.” Whichever alternative is chosen,
the arrangement must achieve the necessary degree
of emission reduction not later than December 31,
1978. Use of intermittent controls after that date
is not permitted. See Section 119(c)(2)(B) and
(C), 42 U.S.C. (Supp. IV) 1857c-10(¢c) (2)(B) and
(C).

Since the purpose of this legislation was to en-
courage certain power plants to convert from oil or
gas to coal and to provide relief to those plants that
switched to coal because of the oil supply crisis, it
is inconceivable that Congress intended to impose
on such sources a greater burden than if they had
not converted. Accordingly, Congress must have as-
sumed that intermittent controls were not permitted
prior to the 1974 amendment.

CONCLUSION

For the reasons stated, it is respectfully sub-
mitted that if the Court agrees that the case is moot,
the petition for a writ of certiorari should be grant-
ed, the judgment should be vacated and the case
remanded for dismissal as moot. Otherwise, the
petition for a writ of certiorari should be denied.
