While federal installations discharging water pollutants are
obliged, under § 313 of the Federal Water Pollution Control
Act Amendments of 1972 (Amendments), to comply to the same extent
as nonfederal facilities with state "requirements respecting
control and abatement of pollution," obtaining a permit from a
State with a federally approved permit program is not among such
requirements. Federal installations are subject to state regulation
only when and to the extent that congressional authorization is
clear and unambiguous,

here the Amendments do not subject federal facilities to state
permit requirements with the requisite degree of clarity. Pp.

MR. JUSTICE WHITE delivered the opinion of the Court.
The issue in this case which arises under the Federal Water
Pollution Control Act Amendments of 1972 (Amendments), 86 Stat.
816, 33 U.S.C. § 1251
et seq. (1970 ed., Supp. IV),
is whether federal installations discharging water pollutants in a
State with a federally approved permit program are to secure their
permits from the State, or from the Environmental Protection
Page 426 U. S. 202
Agency (EPA). As with the related Clean Air Act issue decided
this day in
Hancock v. Train, ante p.
426 U. S. 167,
decision of the specific statutory question -- whether obtaining a
state permit is among those "requirements respecting control and
abatement of pollution" with which federal facilities must comply
under § 313 of the Amendments [
Footnote 1] -- is informed by constitutional principles
governing submission of federal installations to state regulatory
authority.
I
Before it was amended in 1972, the Federal Water Pollution
Control Act [
Footnote 2]
employed ambient water quality standards specifying the acceptable
levels of pollution in a State's interstate navigable waters as the
primary mechanism in its program for the control of water
pollution. [
Footnote 3] This
program based on water quality standards, which were to serve both
to guide performance by polluters and to trigger legal action to
abate pollution, proved ineffective. The problems stemmed from the
character of the standards themselves, which focused on the
tolerable effects, rather than the preventable causes, of water
pollution, from the awkwardly shared federal and state
responsibility for promulgating such standards, [
Footnote 4] and from the cumbrous enforcement
procedures. These combined to make it very difficult to develop
and
Page 426 U. S. 203
enforce standards to govern the conduct of individual
polluters.
Some States developed water quality standards and plans to
implement and enforce them, and some relied on discharge permit
systems for enforcement. Others did not, and, to strengthen the
abatement system, federal officials revived the Refuse Act of 1899,
§ 13, 30 Stat. 1152, 33 U.S.C. § 407, which prohibits the
discharge of any matter into the Nation's navigable waters except
with a federal permit. [
Footnote
5] Although this direct approach to water pollution abatement
proved helpful, it also was deficient in several respects: the goal
of the discharge permit conditions was to achieve water quality
standards, rather than to require individual polluters to minimize
effluent discharge, the permit program was applied only to
industrial polluters, some dischargers were required to obtain both
federal and state permits, and federal permit authority was shared
by two federal agencies. [
Footnote
6]
In 1972, prompted by the conclusion of the Senate Committee on
Public Works that "the Federal water pollution control program . .
. has been inadequate in every vital aspect," [
Footnote 7] Congress enacted the Amendments,
declaring "the national goal that the discharge of pollutants into
the navigable waters be
eliminated by 1985." [
Footnote 8]
Page 426 U. S. 204
For present purposes, the Amendments introduced two major
changes in the methods to set and enforce standards to abate and
control water pollution. First, the Amendments are aimed at
achieving maximum "effluent limitations" on "point sources," as
well as achieving acceptable water quality standards. A point
source is "any discernible, confined and discrete conveyance . . .
from which pollutants are or may be discharged." [
Footnote 9] An "effluent limitation," in
turn, is
"any restriction established by a State or the Administrator on
quantities, rates, and concentrations of chemical, physical,
biological, and other constituents which are discharged from point
sources . . . including schedules of compliance. [
Footnote 10]"
Such direct restrictions on discharges facilitate enforcement by
making it unnecessary to work backward from an over-polluted body
of water to determine which point sources are responsible and which
must be abated. In addition, a discharger's performance is now
measured against strict technology-based [
Footnote 11] effluent limitations -- specified levels
of treatment -- to which it must conform, rather than against
limitations derived from water
Page 426 U. S. 205
quality standards to which it and other polluters must
collectively conform. [
Footnote
12]
Second, the Amendments establish the National Pollutant
Discharge Elimination System (NPDES) [
Footnote 13] as a means of achieving and enforcing the
effluent limitations. Under the NPDES, it is unlawful for any
person to discharge a pollutant without obtaining a permit and
complying with its terms. [
Footnote 14] An NPDES permit serves to transform
generally applicable effluent limitations and other standards --
including those based on water quality -- into the obligations
(including a timetable for compliance) of the individual
discharger, and the Amendments provide for direct administrative
and judicial enforcement of permits. §§ 309 and 505, 33
U.S.C. §§ 1319 and 1365 (1970 ed., Supp. IV). With few
exceptions, for enforcement purposes, a discharger in compliance
with the terms and conditions of an NPDES permit is deemed to be in
compliance with those sections of the Amendments on which the
permit conditions are based. § 402(k), 33 U.S.C. §
1342(k) (1970 ed., Supp. IV). In short, the permit defines, and
facilitates compliance with, and enforcement of, a preponderance of
a discharger's obligations under the Amendments.
Page 426 U. S. 206
NPDES permits are secured, in the first instance, from the EPA,
which issues permits under the authority of § 402(a)(1), 33
U.S.C. § 1342(a)(1) (1970 ed., Supp. IV). Section 402(a)(3)
requires the EPA permit program and permits to conform to the
"terms, conditions, and requirements" of § 402(b). [
Footnote 15] Consonant
Page 426 U. S. 207
with its policy "to recognize, preserve, and protect the primary
responsibilities and rights of States to prevent,
Page 426 U. S. 208
reduce, and eliminate pollution," [
Footnote 16] Congress also provided that a State may
issue NPDES permits "for discharges into navigable waters within
its jurisdiction," but only upon EPA approval of the State's
proposal to administer its own program. The EPA may require
modification or revision of a submitted program, but when a plan is
in compliance with the EPA's guidelines under § 304(h)(2), 33
U.S.C. § 1314(h)(2) (1970 ed., Supp. IV), and is supported by
adequate authority to achieve the ends of §§
402(b)(1)-(9), n. 15,
supra, and to administer the
described program, the EPA shall approve the program and "suspend
the issuance of permits under [§ 402(a)] as to those navigable
waters subject to such program." [
Footnote 17]
The EPA retains authority to review operation of a State's
permit program. Unless the EPA waives review for particular classes
of point sources or for a particular permit application,
§§ 402(d)(3), (e), 33 U.S.C. §§ 1342(d)(3), (e)
(1970 ed., Supp. IV), a State is to forward a copy of each permit
application to the EPA for review, and no permit may issue if the
EPA objects that issuance of the permit would be "outside the
guidelines and requirements" of the Amendments. §§
402(d)(1), (2), 33 U.S.C. §§ 1342(d)(1), (2) (1970 ed.,
Supp. IV). In addition to this review authority, after notice and
opportunity to take action, the EPA may withdraw approval of a
state permit program which is not being administered in compliance
with § 402. § 402(c)(3), 33 U.S.C. § 1342(c)(3)
(1970 ed., Supp. IV).
Page 426 U. S. 209
The Amendments also sought to enlist "every Federal agency . . .
to provide national leadership in the control of water pollution in
[its] operations." [
Footnote
18] To do so, 33 U.S.C. § 1171(a), which required federal
agencies,
"consistent with the paramount interest of the United States as
determined by the President [to] insure compliance with applicable
water quality standards,"
was amended by adding § 313, [
Footnote 19] providing that federal installations
must
"comply with Federal, State, interstate, and local requirements
respecting control and abatement of pollution to the same extent
that any person is subject to such requirements."
33 U.S.C. § 1323 (1970 ed., Supp. IV).
II
On May 14, 1973, the Acting EPA Administrator approved the State
of California's request to administer its own NPDES permit program
and, effective that date, suspended EPA issuance of all permits for
"all discharges in the State of California, other than those from
agencies and instrumentalities of the Federal government." App. 18.
Soon after this first approval of a state program and after
correspondence exchanging views on a State's authority to issue
permits to federal installations, the EPA informed the State of
Washington that it "does not have the prerogative to delegate
permit issuance for Federal facilities to any state."
Id.
at 6. Shortly
Page 426 U. S. 210
thereafter, the State of Washington's permit program was
rejected as "missing important components,"
id. at 7, the
EPA reaffirming its position that it had "sole authority to issue
permits to federal facilities."
Id. at 25.
California and Washington filed petitions for review under
§ 509(b)(1), which authorizes a court of appeals to review
"the Administrator's action . . . (D) in making any determination
as to a State permit program submitted under section 402(b)."
[
Footnote 20] The two States
argued that § 313 authorized States with approved NPDES permit
programs to require federal dischargers to obtain state permits.
The States also argued that § 402 gave the EPA no authority to
suspend operation of its permit program in a State only for
nonfederal dischargers. The Court of Appeals agreed. Mindful of
"strong structural and terminological similarities between the
Clean Air Act and the 1972 Water Pollution Control Act Amendments,"
and of the division in the Courts of
Page 426 U. S. 211
Appeals as to the meaning of § 118 of the Clean Air Act,
[
Footnote 21] the court
found in the Amendments several measures, which it thought had no
counterpart in the Clean Air Act and which, in its view, indicated
that federal dischargers were subject to state permit requirements.
However the Clean Air Act issue might be resolved, the court
concluded that those other indications in the Amendments were
sufficiently clear to satisfy the appropriate constitutional
conditions for subjecting federal installations to state
regulation, and held that federal installations were required to
secure state NPDES permits. 511 F.2d 963, 973 (CA9 1975). We
granted the EPA's petition for certiorari, 422 U.S. 1041 (1975),
and now reverse the judgment of the Court of Appeals.
III
Our decision in this case is governed by the same fundamental
principles applied today in
Hancock v. Train, ante at
426 U. S. 179:
federal installations are subject to state regulation only when and
to the extent that congressional authorization is clear and
unambiguous. As in
Hancock v. Train, we must determine
whether Congress has subjected federal installations to the degree
of state control urged by the States. The only section of the
Amendments expressly obliging federal installations to comply with
general measures to abate water pollution [
Footnote 22] is § 313, which provides in
part:
"Each department, agency, or instrumentality of the executive,
legislative, and judicial branches of the Federal Government (1)
having jurisdiction
Page 426 U. S. 212
over any property or facility, or (2) engaged in any activity
resulting, or which may result, in the discharge or runoff of
pollutants shall comply with Federal, State, interstate, and local
requirements respecting control and abatement of pollution to the
same extent that any person is subject to such requirements,
including the payment of reasonable service charges."
86 Stat. 875, 33 U.S.C. § 1323 (1970 ed., Supp. IV). Except
for the reference to service charges, § 313 is virtually
identical to § 118 of the Clean Air Act, 42 U.S.C. §
1857f. [
Footnote 23] Taken
alone, § 313, like § 118 of the Clean Air Act, states
only to what extent -- the same as any person -- federal
installations must comply with applicable state requirements.
Section 313 does not expressly provide that federal dischargers
must obtain state NPDES permits. Nor does § 313 or any other
section of the Amendments expressly state that obtaining a
state
Page 426 U. S. 213
NPDES permit is a "requirement respecting control and abatement
of pollution." [
Footnote
24]
The EPA's position is that the Amendments make clear
"only that facilities of the executive, legislative and judicial
branches operating within the states must comply with the
applicable effluent limitations and compliance schedules
promulgated by the particular state pursuant to its E.P.A.-approved
implementation plan,"
as incorporated in EPA-issued permits, not that they comply with
"state regulations demanding that sources of discharges --
including federal facilities -- obtain discharge permits."
[
Footnote 25] The States
claim that this distinction
"between permits and effluent 'limitations' . . . ignores the
fact that the mechanism by which such 'limitations' are formulated
and applied to individual dischargers is by the permit system
established in section 402. [
Footnote 26]"
From this, the States, recognizing that § 313 itself does
not subject federal dischargers to their permit programs, derive
their principal argument that a State's authority to subject
federal installations to its EPA-approved permit program must be
implied from the practical needs of administering an NPDES permit
program, and that this implication is sufficiently clear to satisfy
the governing constitutional standard. In their view, the EPA's
agreement
Page 426 U. S. 214
that the States have authority to develop and set the
substantive content of permits issued to federal dischargers is an
empty concession; without being able to subject federal
installations to its own NPDES program, a State is without
effective means to formulate and apply the conditions which the EPA
must make part of the permit for each individual source.
Congress used virtually the same language in § 313 as in
§ 118 of the Clean Air Act, and our conclusion in
Hancock
v. Train, ante, p.
426 U. S. 167,
that the Clean Air Act is without clear indication that Congress
intended federal installations emitting air pollutants to be
subject to the permit program of a State's implementation plan
makes it difficult for the States to establish that for similar
purposes the same language becomes sufficiently clear in § 313
of the Amendments. There are, of course, significant differences
between the Clean Air Act and the Amendments. Only the Amendments
expressly provide for a permit program to aid in abating pollution.
In comparison with the Clean Air Act, the Amendments give the EPA a
more prominent role in relation to the States; a State is not
required to develop an NPDES permit program, and, until a State
does develop a permit program, all dischargers in the State are
subject to a permit program developed and carried out by the EPA.
In addition, under the Amendments, the EPA's role in developing the
effluent limitations that serve as the basis for a State's NPDES
permit conditions [
Footnote
27] is more prominent than in developing the ambient air
quality
Page 426 U. S. 215
standards which are the foundation of the emission standards in
a State's Clean Air Act implementation plan. In the aggregate,
these differences tend to support the EPA's position, and, in any
event, they hardly require a conclusion contrary to
Hancock v.
Train, particularly since, in the Court of Appeals' words,
"certain parts of the legislative history would seem to indicate
that the 'requirements' language of Section 313 refers simply and
solely to substantive"
standards, to effluent limitations and standards and schedules
of compliance. 511 F.2d at 969. [
Footnote 28]
Page 426 U. S. 216
With these obstacles to the States' position in mind, we examine
the reasons which collectively led the Court of Appeals to conclude
and the States to contend that the Amendments clearly require
federal installations to secure state NPDES permits. The Court of
Appeals first concluded that such an implication appears in the
final phrase of the first sentence of § 313 -- "including the
payment of reasonable service charges." This language, it is
argued, must refer to charges incident to a state permit program:
if payment of such charges is a "requirement," it must be that
Congress intended federal installations to secure state NPDES
permits, for there would be no reason to order federal
installations to pay fees for a permit which they are not required
to obtain. However, the legislative history of § 313 casts no
light on the meaning of this clause, [
Footnote 29] and it is not immediately
Page 426 U. S. 217
clear from the face of § 313 that the phrase does refer to
application and service charges associated with an NPDES permit
program. Indeed, the term "service charges" might as well be taken
to refer to recurring charges for performing a service such as
treating sewage as to fees for accepting and processing a permit
application. The EPA so reads the statute, and it is not an
unreasonable construction. [
Footnote 30] At the very least, the "service charges"
language hardly satisfies the rule that federal agencies are
subject to state regulation only when and to the extent Congress
has clearly expressed such a purpose.
The Court of Appeals also found textual support for its
conclusion in § 510 of the Amendments. [
Footnote 31] This
Page 426 U. S. 218
section, which is patterned after § 116 of the Clean Air
Act, [
Footnote 32] provides
that the States may set more restrictive standards, limitations,
and requirements than those imposed under the Amendments. [
Footnote 33] Section 510 quite
plainly was intended to strengthen state authority. It may also
have been intended to permit the States to impose stricter
standards and effluent limitations on federal installations than
would have been imposed under an EPA permit in the absence of an
approved state NPDES program. But this hardly answers the question
before us, which is whether these higher standards are to be
enforced through a state, rather than an EPA, permit system. It is
nevertheless argued that the meaning of the phrase "requirements
respecting control and abatement of pollution" used in § 313
is informed by its use in § 510, an argument akin to one made
and rejected in
Hancock v. Train, ante at
426 U. S.
186-187, n. 47. We reject it here for much the same
reasons: the phrase cannot have the same meaning in both sections,
and there is scant reason to credit the States' position that
treating "standards" and "requirements" disjunctively in § 510
somehow dictates that "requirements" in § 313 shall embrace
more than "standards."
Another contention drawing upon § 510 is that a State's
authority to impose stricter substantive standards on federal
installations is meaningless if a State cannot subject federal
dischargers to its permit system. This is simply an adjunct
[
Footnote 34] to the States'
primary argument
Page 426 U. S. 219
that no state NPDES permit system can function effectively
unless federal dischargers are required to obtain state permits,
and that federal installations are therefore impliedly, but
clearly, subject to state permit programs. We cannot agree.
Before a State has its NPDES program approved, it is the EPA
which issues permits for all dischargers, federal and nonfederal.
Since the Amendments do not require the States to develop NPDES
programs, we must assume that the Congress was satisfied that the
EPA could administer the program not only by promulgating the
nationwide effluent limitations and other standards required by the
Amendments, but also by translating those limitations into the
conditions of individual permits for individual federal and
nonfederal dischargers. We must also assume that the Congress
contemplated that there may be some States which would elect not to
develop an NPDES program, but would nonetheless determine -- as
§ 510 permits -- to adopt water quality standards or other
limitations stricter than those the EPA itself had promulgated and
would otherwise apply. This being the case, Congress must have
contemplated that the EPA was capable of issuing permits in that
State -- to both federal and nonfederal dischargers -- and of
enforcing those stricter standards. Some of those standards -- in
fact, all but those pegged to the quality of the receiving waters
-- could be translated into permit conditions for each discharger
without coordinating the conditions in other permits, because the
effluent limitations in the Amendments are technology-based and the
timetable by which compliance is to be achieved is not made to
depend on the performance of other dischargers. Other standards,
primarily those involving water quality standards, would require
coordination among the permit conditions of numerous polluters --
federal and nonfederal,
Page 426 U. S. 220
and it is evident that Congress contemplated that the EPA was
capable of carrying out this function as well.
The presence of the EPA as a permit-issuing authority means
that, although federal dischargers are not securing state NPDES
permits, they are nevertheless being subjected to the
administrative authority of a federal agency which is required to
make a State's
"more stringent limitation[s], including those necessary to meet
water quality standards, treatment standards, or schedules of
compliance"
part of the conditions of the permits it must issue. [
Footnote 35] We recognize that there
may be some problems of coordination between the EPA and the state
pollution control agency in the implementation of state water
quality standards. State officials may view the EPA implementation
of a State's -- or its own -- water quality standards as placing a
disproportionate share of the additional abatement effort on the
nonfederal dischargers in the State, thereby obligating the State
to impose undesirably restrictive effluent limitations on those
nonfederal -- predominantly private -- dischargers. At the same
time, Congress might have been apprehensive that
Page 426 U. S. 221
state regulatory officials, if in the position to do so, would
impose a disproportionate share of the burden on federal
dischargers. However that may be, we believe that these possible
problems of coordination in the administration of water quality
standards fail to provide an adequate basis for finding a clear
congressional intention to subject federal dischargers to the
degree of control inherent in adhering to state permit requirements
respecting water quality standards. [
Footnote 36]
The States make several other arguments in support of their
position that Congress intended federal dischargers to be subject
to state NPDES permit programs, that "requirements" in § 313
include securing a state NPDES permit. We find none of them
persuasive. They assert that, since the EPA's authority to issue
permits to federal dischargers stems at least in part from §
313, it is "capricious" to conclude that the word "requirements" in
§ 313 refers to permits issued by the EPA under § 402(a),
but not to permits issued by a State under § 402(b). The
answer to this argument is that the EPA's authority to issue
permits to federal, as well
Page 426 U. S. 222
as nonfederal dischargers is granted by § 402(a), not
§ 313. Nor does the "requirement" that a federal discharger
secure a permit stem from § 313; that also arises from §
402(a) alone. [
Footnote
37]
The States, like the Court of Appeals, 511 F.2d at 973, also
find support for their position in § 505 of the Amendments, 33
U.S.C. § 1365 (1970 ed., Supp. IV), which provides that a
citizen may commence civil actions in district court
"against any person (including . . . the United States . . . )
who is alleged to be in violation of . . . an effluent standard or
limitation under this Act. . . ."
§ 505(a)(1), 33 U.S.C. § 1365(a)(1) (1970 ed., Supp.
IV). One of the definitions of "effluent standard or limitation"
for purposes of § 505 is
"a permit or condition thereof issued under section 402 of this
Act, which is in effect under this
Page 426 U. S. 223
Act (including a requirement applicable by reason of section 313
of this Act)."
§ 505(f)(6), 33 U.S.C. § 1365(f)(6) (1970 ed., Supp.
IV). California reads § 505(f) to equate a "requirement" under
§ 313 with a permit issued under § 402, as if §
505(f)(6) were phrased:
"any permit or condition thereof issued under Section 402 of
this Act, which is in effect under this Act (including one issued
to a federal discharger)."
In a similar vein, Washington asserts that "[c]itizens may bring
suit to enforce permits issued under Section 402," including
"permits and conditions thereof applicable because of Section 313."
Brief 18. It is more reasonable, however, to interpret
"requirement" in the parenthetical expression in § 505(f)(6)
as referring principally to a "condition," not to a "permit." This
is because of the Amendments' primary reliance on the NPDES as a
means to abate and control water pollution.
See supra at
426 U. S. 205.
For enforcement purposes, § 402(k) deems a permit holder who
is in compliance with the terms of its permit to be in compliance
"with sections 301, 302, 306, 307, and 403, except any standard
imposed under section 307 for a toxic pollutant injurious to human
health." 33 U.S.C. § 1342(k) (1970 ed., Supp. IV). Thus, the
principal means of enforcing the pollution control and abatement
provisions of the Amendments is to enforce compliance with a
permit. Of the six subdivisions of § 505(f) defining "effluent
standard or limitation," only § 505(f)(6) refers to any of the
standards or limitations
as translated into the conditions of
an NPDES permit. Thus, while §§ 505(f)(2)-(4) permit
suits for violation of effluent standards or limitations
promulgated under §§ 301, 302, 306, and 307, a suit
against a permit holder will necessarily be brought under the
definition in § 505(f)(6); unless the plaintiff can show
violation of the permit condition, violation of the Amendments
cannot be established. This is true both
Page 426 U. S. 224
for conditions imposed in accordance with EPA-promulgated
effluent limitations and standards and for those imposed in
accordance with more stringent standards and limitations
established by a State pursuant to § 510. The reference in
§ 505(f)(6) to requirements applicable by reason of § 313
is to be read as making clear that all dischargers (including
federal dischargers) may be sued to enforce permit conditions
whether those conditions arise from standards and limitations
promulgated by the Administrator or from stricter standards
established by the State. [
Footnote 38] In short, we cannot accept the States'
position that the meaning of "requirements" in § 313 they urge
is supported by its use in § 505(f)(6).
Finally, it is argued that, when a State submits a plan in
conformity with § 402, the EPA must approve it and must then
suspend the issuance of all EPA permits with respect to the waters
covered by the plan, including permits to federal agencies.
[
Footnote 39] Because it is
inconceivable
Page 426 U. S. 225
that Congress would have intended federal instrumentalities to
operate without permits, it is contended that Congress anticipated
the state permit system to apply.
Page 426 U. S. 226
The difficulty with this position is that, under § 402, the
EPA obviously need not, and may not, approve a state plan which the
State has no authority to issue because it conflicts with federal
law. [
Footnote 40] If §
313 expressly said that federal instrumentalities must comply with
state discharge standards, but need not secure state permits, it
would be untenable to urge that a state plan which nevertheless
attempts to subject federal agencies to state permit requirements
would have to be approved simply because it was otherwise in
compliance with § 402. As we construe § 313, this is the
situation before us. By the same token, we do not think that EPA
permit authority with respect to federal agencies terminates when
the EPA purports to approve a state plan except for that portion of
it which seeks to subject federal instrumentalities to the state
permit regime.
From the outset of the EPA's administration of the NPDES and in
its first regulations establishing the § 304(h)(2) guidelines
for state NPDES permit programs,
see 37 Fed.Reg. 28391
(1972), the EPA has taken the position that authority to suspend
issuance of EPA permits extends only "to those point sources
subject to such approved program." 40 CFR § 124.2(b) (1975).
The implications that the state program would only embrace
nonfederal dischargers on those navigable waters subject to the
program, and that the EPA
Page 426 U. S. 227
was authorized to, and would, continue to issue permits to
federal dischargers were soon made explicit in 40 CFR §§

Footnote 41] which provide that federal dischargers are
to comply with the EPA permit program, and that state NPDES permit
programs do not cover federal agencies and instrumentalities. This
construction by the agency charged with enforcement of the
Amendments is reasonable, and, in the absence of any cogent
argument that it is contrary to congressional intentions, we
sustain the EPA's understanding that the States are without
authority to require federal dischargers to secure their NPDES
permits. [

IV
Our conclusion is that the Federal Water Pollution Control Act
Amendments of 1972 do not subject federal facilities to state NPDES
permit requirements with the requisite degree of clarity. Should it
be the intent of Congress to have the EPA approve a state NPDES
program regulating federal, as well as nonfederal, point sources
and suspend issuance of NPDES permits as to
Page 426 U. S. 228
all point sources discharging into the navigable waters subject
to the State's program, it may legislate to make that intention
manifest.
The judgment of the Court of Appeals is
Reversed.
MR. JUSTICE STEWART and MR. JUSTICE REHNQUIST dissent. They
agree substantially with the reasoning of the Court of Appeals for
the Ninth Circuit in this case, 511 F.2d 963, and they would,
accordingly, affirm its judgment.

"At any time after the promulgation of the guidelines required
by subsection (h)(2) of section 304 of this Act, the Governor of
each State desiring to administer its own permit program for
discharges into navigable waters within its jurisdiction may submit
to the Administrator a full and complete description of the program
it proposes to establish and administer under State law or under an
interstate compact. In addition, such State shall submit a
statement from the attorney general (or the attorney for those
State water pollution control agencies which have independent legal
counsel), or from the chief legal officer in the case of an
interstate agency, that the laws of such State, or the interstate
compact, as the case may be, provide adequate authority to carry
out the described program. The Administrator shall approve each
such submitted program unless he determines that adequate authority
does not exist:"
"(1) To issue permits which -- "
"(A) apply, and insure compliance with, any applicable
requirements of sections 301, 302, 306, 307, and 403;"
"(B) are for fixed terms not exceeding five years; and"

"(i) violation of any condition of the permit;"
"(ii) obtaining a permit by misrepresentation, or failure to
disclose fully all relevant facts;"
"(iii) change in any condition that requires either a temporary
or permanent reduction or elimination of the permitted
discharge;"
"(D) control the disposal of pollutants into wells;"
"(2)(A) To issue permits which apply, and insure compliance
with, all applicable requirements of section 308 of this Act,
or"
"(B) To inspect, monitor, enter, and require reports to at least
the same extent as required in section 308 of this Act;"
"(3) To insure that the public, and any other State the waters
of which may be affected, receive notice of each application for a
permit and to provide an opportunity for public hearing before a
ruling on each such application;"

whose waters may be affected by the issuance of a permit may submit
written recommendations to the permitting State (and the
Administrator) with respect to any permit application and, if any
part of such written recommendations are not accepted by the
permitting State, that the permitting State will notify such
affected State (and the Administrator) in writing of its failure to
so accept such recommendations together with its reasons for so
doing;"

of the Secretary of the Army acting through the Chief of Engineers,
after consultation with the Secretary of the department in which
the Coast Guard is operating, anchorage and navigation of any of
the navigable waters would be substantially impaired thereby;"
"(7) To abate violations of the permit or the permit program,
including civil and criminal penalties and other ways and means of
enforcement;"
"(8) To insure that any permit for a discharge from a publicly
owned treatment works includes conditions to require adequate
notice to the permitting agency of (A) new introductions into such
works of pollutants from any source which would be a new source as
defined in section 306 if such source were discharging pollutants,
(b) new introductions of pollutants into such works from a source
which would be subject to section 301 if it were discharging such
pollutants, or (C) a substantial change in volume or character of
pollutants being introduced into such works by a source introducing
pollutants into such works at the time of issuance of the permit.
Such notice shall include information on the quality and quantity
of effluent to be introduced into such treatment works and any
anticipated impact of such change in the quantity or quality of
effluent to be discharged from such publicly owned treatment works;

States to do so" and subject to several limitations, to exempt
certain federal point sources from "compliance with any such a
requirement." Any exemptions granted must be reported annually to
the Congress. The President may grant no exemptions from the
requirements of §§ 306 and 307 of the Amendments, 33
U.S.C. §§ 1316, 1317 (1970 ed., Supp. IV), which provide,
respectively, for standards of performance regulating "new sources"

discharges introduced into "treatment works," defined in §

process.

The Court of Appeals appeared to recognize as much; for even

"had required only that federal agencies comply with 'applicable
water quality standards,' without specifying whether compliance was
limited to the substantive content of the 'standards' referred to,
and without specifying whether those standards included state
standards,"
the court also concluded that the enactment of § 313, in
and of itself, would not sustain an inference that federal
installations were to secure state permits. 511 F.2d 963, 967.

In both the Senate bill, S. 2770, 92d Cong., 1st Sess. (1971), 2
Leg.Hist. 1676-1677, and the House amendment, as reported, H.R.
11896, 92d Cong., 2d Sess. (1972), 1 Leg.Hist. 1040-1041, §
313 provided that federal installations must
"comply with Federal, State, interstate, and local requirements
respecting control and abatement of [water] pollution to the same
extent that any person is subject to such requirements, including
the payment of reasonable service charges."
(The House version, like § 313 as enacted, did not include
the bracketed word.) In the Report accompanying S. 2770, § 313
was described as
"requir[ing] that Federal facilities meet the same effluent
limitations as private sources of pollut[i]on, unless the Federal
facility is specifically exempted by the President. . . . This
section requires that Federal facilities meet all
control
requirements as if they were private citizens."
S.Rep. No. 92-414,
supra at 67, 2 Leg.Hist. 1485
(emphasis added). Later, in relating how § 313 provides that
the President may exempt certain federal sources from "such
requirements," the Report explained the requirements from which a
federal facility may be exempted in terms of controlling its
pollution, controlling actual physical discharge:
"The Committee recognizes, however, that it may be in the
paramount interest of the United States that a plant or facility
not achieve full water pollution control within the time
required."
S.Rep. No. 92 414,
supra at 68, 2 Leg.Hist. 1486.
The House Report also first described the "requirements" of
§ 313 as "effluent limitations":
"This section requires that Federal facilities meet the same
effluent limitations, other limitations, performance standards,
toxic effluent standards and thermal discharge regulations as
private sources of pollution. . . ."
H.R.Rep. No. 92-911,
supra at 118, 1 Leg.Hist. 805.
The absence of any reference to federal facilities' securing a
state NPDES permit -- respondent California agrees the "reports are
silent with respect to the issues in this case" (Brief 40) --
continues through the Conference Report which indicates that there
were no differences to be resolved between the House and Senate
versions of § 313. The Report summarized the Senate bill as
"requir[ing] Federal facilities to meet the same effluent
limitations as other sources of pollution," and the House amendment
as requiring them "to meet the same requirements as private sources
of pollution." S.Conf.Rep. No. 92-1236, p. 135 (1972), 1 Leg.Hist.
318.
[
Footnote 29]
The Court of Appeals, 511 F.2d at 969-970, found the legislative
history of § 313 silent on the meaning of the clause. The
States' only support for their construction of the clause is the
"recollection" of one of the members of the Senate Public Works
Committee, expressed in September, 1974, nearly two years after the
Amendments were enacted, and while this litigation was pending in
the Court of Appeals, that the language was intended to authorize a
federal agency to pay a fee to the State as a part of the
requirement that it obtain a state discharge permit. Brief for
Respondent California 24 n. 24; Brief for Respondent Washington 20
n. 15, both citing 120 Cong.Rec. 31216 (1974) (remarks of Sen.
Baker).
[
Footnote 30]
The EPA explains that the absence of such direction or
clarification in the Clean Air Act supports its position, because
there are no sewers to carry away air emissions, and hence no
comparable services for which to make clear that appropriate
charges may be levied.

Through § 402(a)(2), § 402(b)(1)(A) requires the

regulation, or required to implement any applicable water quality
standard established pursuant to this Act."
86 Stat. 844, 33 U.S.C. § 1311(b)(1)(C) (1970 ed., Supp.
IV) (emphasis added).
[
Footnote 36]
Respondent California argues that the obligation of federal
dischargers to meet state effluent limitations necessarily implies
state power to subject them, in turn, to state schedules of
compliance, state administrative hearings to determine those
schedules of compliance, and therefore to the entire gantlet of
state permit proceedings, and finally to the permit itself. Brief
32-37. The defect in this argument is its opening assertion that
federal dischargers must comply with a State's
individualized effluent limitations, that is, permit
conditions such as compliance schedules. We think that the EPA is
correct that federal dischargers are to be governed only by the
same general effluent limitations and other standards and
compliance schedules as other polluters, as embodied in EPA
permits, and that, in issuing permits to federal dischargers, the
EPA is to treat federal dischargers under its NPDES program in the
same way the State would treat nonfederal dischargers under its
program.
[
Footnote 37]
The authority to require permits rests on § 402 alone, not
on § 301(a), and it was under § 402 that the
Administrator issued his regulation subjecting federal
instrumentalities to the EPA permit system. 40 CFR §§
125.2(a)(2), (b) (1975), 38 Fed.Reg. 13528 (1973). Section 301(a)
simply makes it "unlawful" for "any person" not to have the
required permit. That federal agencies, departments, and
instrumentalities are not "persons" within the meaning of §
301(a) and the Amendments,
see § 502(5), 33 U.S.C.
§ 1362(5) (1970 ed., Supp. IV), does not mean either that
federal dischargers are not required to secure NPDES permits or
that their obligation to secure an NPDES permit derives from a
different provision of the Amendments. A federal discharger without
a permit is no less out of compliance with § 402 than a
nonfederal discharger; the federal discharge is, however, not
"unlawful." Section 309 of the Amendments, 33 U.S.C. § 1319
(1970 ed., Supp. IV), which provides for federal enforcement of the
Amendments, mirrors § 301(a)'s differing treatment of federal
and nonfederal sources. Section 309(a)(3), for example, provides
for the EPA to issue orders to "persons" in violation of,
inter
alia, § 301, and to bring a civil action under §
309(b), 33 U.S.C. § 1319(b) (1970 ed., Supp. IV).
See
also §§ 306(e), 307(d), 505(f)(1), 33 U.S.C.
§§ 1316(e), 1317(d), 1365(f)(1) (1970 ed., Supp. IV).
[
Footnote 38]
The Court of Appeals read § 505(f) as explicitly
distinguishing between effluent standards and limitations and other
types of limitations or standards, on the one hand, and a
requirement applicable by reason of § 313, on the other. 511
F.2d at 972. In light of § 402(k), which, for purposes of
§ 505, makes compliance with a permit condition compliance
with most of the sections imposing standards and limitations,
§ 505(f)(6) is the central provision of § 505(f), and, as
outlined in the text, its salient feature is not distinguishing
standards from requirements, but distinguishing standards and
limitations, on the one hand, from the permit conditions embodying
those standards, on the other.
[
Footnote 39]
The legislative history on the EPA's authority to suspend its
permit program is meager, but Congress does not appear to have
concentrated its attention on the question of partial suspension of
the EPA permit program within a State. Thus, from § 402(b),
which permits a State to submit "a full and complete description of
the program it proposes to establish and administer . . . under an
interstate compact" (
see § 103, 33 U.S.C. § 1253
(1970 ed., Supp. IV)), it is evident that Congress clearly
contemplated that the EPA might suspend issuance of § 402(a)
permits only as to some of a State's navigable waters -- those
within the scope of the interstate compact -- and continue to issue
permits to federal and nonfederal dischargers on other waters
within the State. Nonetheless the Senate Report stated that
"the bill provides that after a State submits a program which
meets the criteria established by the Administrator pursuant to
regulations, the Administrator shall suspend his activity in such
State under the Federal permit program."
S.Rep. No. 92-414,
supra at 71, 2 Leg.Hist. 1489. Like
the States' argument that the EPA must withdraw completely from
permit-issuing activity in a State with an approved program, this
statement, on which the States rely, overlooks the possibility of a
State's submitting a plan covering only some of its navigable
waters. Although S. 2770, to which the Report referred, did include
the provision permitting a State to submit a permit program to be
administered under an interstate compact,
see §
402(c)(1), 2 Leg.Hist. 1689, it provided only that the EPA "shall
suspend the issuance of permits under subsection (a) of this
section." The phrase "as to those navigable waters subject to such
program" was part of the House amendment, H.R. 11896, 1 Leg.Hist.
1058, and its inclusion in § 402(c)(1) as enacted was not
discussed in the Reports. Given this misapprehension in the Senate
Report, we find the statement the States rely on to be an
insufficient basis upon which to conclude, as the States urge, that
the committee understood § 402(c)(1) as if it read that upon
approving a state plan the EPA must "suspend its activity in such
State, or part of such State, under the Federal. permit program, as
to federal and nonfederal dischargers."
We are also unpersuaded by the States' argument that by limiting
the EPA's authority to withdraw approval of a state program to
withdrawing approval as to the entire program, Congress emphasized
that only one government shall operate an NPDES permit program
within a State. § 402(c)(3), 33 U.S.C. § 1342(c)(3) (1970
ed., Supp. IV). In our view, rejection of the EPA's proposal that
the bill should be changed to permit withdrawal as to categories or
classes of sources, 1 Leg.Hist. 854-855, reflected a concern that
the States be given maximum responsibility for the permit system,
and that the EPA's review authority be restricted as much as was
consistent with its overall responsibility for assuring attainment
of national goals. H.R.Rep. No. 92-911,
supra at 127, 1
Leg.Hist. 814. Whether the States' maximum responsibility includes
issuing permits to federal installations is, however, the question
before us, and, in view of the substantial review authority the EPA
undoubtedly retains,
see supra at
426 U. S. 208,
its all-or-nothing authority to withdraw approval of a state NPDES
program offers no meaningful support for the States' position that
federal dischargers are required to secure state permits.
[
Footnote 40]
Under § 402(b), there must be ample legal authority to
carry out the issuance of permits under the State's plan.
See n 15,
supra.

Footnote 41]
38 Fed.Reg. 13528 (1973).
[
Footnote 42]
We also find unpersuasive on the issue before us the States
argument, based upon §§ 306(c), 308(c), and 401(a)(6), 33
U.S.C. §§ 1316(c), 1318(c), 1341(a)(6) (1970 ed., Supp.
IV), in which federal facilities are expressly exempted from
certain forms of state regulation under the Amendments. The
argument is that these sections demonstrate that Congress knew how
to exempt federal facilities from state regulation, so that. by not
expressly providing that federal facilities need not secure state
permits, Congress clearly revealed an intention that federal
facilities secure such permits. Although §§ 306, 308, and
401 are of obvious importance to the implementation of the goals
and purposes of the Amendments, they are too incidental to the
NPDES program for their treatment of federal facilities to offer
any meaningful guidance on the question for decision in this
case.
