*611Justice Souter
delivered the opinion of the Court.
The question in these cases is whether Congress has waived the National Government’s sovereign immunity from liability for civil fines imposed by a State for past violations of the Clean Water Act (CWA), 86 Stat. 816, as amended, 38 U. S. C. § 1251 et seq., or the Resource Conservation and Recovery Act of 1976 (RCRA), 90 Stat. 2796, as amended, 42 U. S. C. § 6901 et seq. We hold it has not done so in either instance.
I
The CWA prohibits the discharge of pollutants into navigable waters without a permit. Section 402, codified at 33 U. S. C. § 1342, gives primary authority to issue such permits to the United States Environmental Protection Agency (EPA), but allows EPA to authorize a State to supplant the federal permit program with one of its own, if the state scheme would include, among other features, sufficiently stringent regulatory standards and adequate provisions for penalties to enforce them. See generally 33 U. S. C. § 1342(b) (requirements and procedures for EPA approval of state water-pollution permit plans); see also 40 CFR §§ 123.1-123.64 (1991) (detailed requirements for state plans). RCRA regulates the disposal of hazardous waste in much the same way, with a permit program run by EPA but subject to displacement by an adequate state counterpart. See generally 42 U. S. C. § 6926 (requirements and procedures for EPA *612approval of state hazardous-waste disposal permit plans); see also 40 CFR §§271.1-271.138 (1991) (detailed requirements for state plans).
This litigation began in 1986 when respondent State of Ohio sued petitioner Department of Energy (DOE) in Federal District Court for violations of state and federal pollution laws, including the CWA and RCRA, in operating its uranium-processing plant in Fernald, Ohio. Ohio sought, among other forms of relief, both state and federal civil penalties for past violations of the CWA and RCRA and of state laws enacted to supplant those federal statutes. See, e. g., Complaint ¶ 64 (seeking penalties for violations of state law and of regulations issued pursuant to RCRA); id., ¶ 115 (seeking penalties for violations of state law and of CWA).1 Before the District Court ruled on DOE’s motion for dismissal, the parties proposed a consent decree to settle all but one substantive claim,2 and Ohio withdrew all outstanding claims for relief except its request for civil penalties for DOE’s alleged past violations. See Consent Decree Between DOE and Ohio, App. 63. By a contemporaneous stipulation, DOE and Ohio agreed on,.the. amount of civil penalties DOE will owe if it is found liable for them, see Stipulation Between DOE and Ohio, id., at 87. The parties thus left for determination under the motion to dismiss only the issue we consider today: whether Congress has waived the National Government’s sovereign immunity from liability for civil fines imposed for past failure to comply *613with the CWA, RCRA, or state law supplanting the federal regulation.
DOE admits that the CWA and RCRA obligate a federal polluter, like any other, to obtain permits from EPA or the state permitting agency, see Brief for Petitioner DOE 24 (discussing CWA); id., at 34-40 (discussing RCRA).3 DOE also concedes that the CWA and RCRA render federal agencies liable for fines imposed to induce them to comply with injunctions or other judicial orders designed to modify behavior prospectively, which we will speak of hereafter as “coercive fines.” See id., at 19-20, and n. 10; see also n. 14, infra. The parties disagree only on whether the CWA and RCRA, in either their “federal-facilities”4 or “citizen-suit”5 sections, waive federal sovereign immunity from liability for fines, *614which we will refer to as “punitive,” imposed to punish past violations of those statutes or state laws supplanting them.
The United States District Court for the Southern District of Ohio held that both statutes waived federal sovereign immunity from punitive fines, by both their federal-facilities and citizen-suit sections. 689 F. Supp. 760 (1988). A divided panel of the United States Court of Appeals for the Sixth Circuit affirmed in part, holding that Congress had waived immunity from punitive fines in the CWA’s federal-facilities section and RCRA’s citizen-suit section, but not in RCRA’s federal-facilities section. 904 F. 2d 1058 (1990).6 Judge Guy dissented, concluding that neither the CWA’s federal-facilities section nor RCRA’s citizen-suit section sufficed to provide the waiver at issue. Id., at 1065-1069.
In No. 90-1341, DOE petitioned for review insofar as the Sixth' Circuit found any waiver of immunity from punitive fines, while in No. 90-1517, Ohio cross-petitioned on the holding that RCRA’s federal-facilities section failed to effect such a waiver.7 We consolidated the two petitions and granted certiorari, 500 U. S. 951 (1991).8
*615I — I
We start with a common rule, with which we presume congressional familiarity, see McNary v. Haitian Refugee Center, Inc., 498 U. S. 479, 496 (1991), that any waiver of the National Government’s sovereign immunity must be unequivocal, see United States v. Mitchell, 445 U. S. 535, 538-539 (1980). “Waivers of immunity must be ‘construed strictly in favor of the sovereign,’ McMahon v. United States, 342 U. S. 25, 27 (1951), and not ‘enlarge[d]... beyond what the language requires.’ Eastern Transportation Co. v. United States, 272 U. S. 675, 686 (1927).” Ruckelshaus v. Sierra Club, 463 U. S. 680, 685-686 (1983). By these lights we examine first the two statutes’ citizen-suit sections, which can be treated together because their relevant provisions are similar, then the CWA’s federal-facilities section, and, finally, the corresponding section of RCRA.
A
So far as it concerns us, the CWA’s citizen-suit section reads that
“any citizen may commence a civil action on his own behalf—
“(1) against any person (including . . . the United States . . .) who is alleged to be in violation of (A) an effluent standard or limitation under this chapter or (B) an order issued by the Administrator or a State with respect to such a standard or limitation ....
“The district courts shall have jurisdiction ... to enforce such an effluent standard or limitation, or such an order ... as the case may be, and to apply any appro*616priate civil penalties under [33 U. S. C. § 1319(d)].” 33 U. S. C. § 1365(a).
The relevant part of the corresponding section of RCRA is similar:
“[A]ny person may commence a civil action on his own behalf —
“(1)(A) against any person (including . . . the United States) . . . who is alleged to be in violation of any permit, standard, regulation, condition, requirement, prohibition, or order which has become effective pursuant to this chapter .. .
“(B) against any person, including the United States . . . who has contributed or who is contributing to the past or present handling, storage, treatment, transportation, or disposal of any solid or hazardous waste which may present an imminent and substantial endangerment to health or the environment....
“. . . The district court shall have jurisdiction ... to enforce the permit, standard, regulation, condition, requirement, prohibition, or order, referred to in paragraph (1)(A), to restrain any person who has contributed or who is contributing to the past or present handling, storage, treatment, transportation, or disposal of any solid or hazardous waste referred to in paragraph (1)(B), to order such person to take such other action as may be necessary, or both,. . . and to apply any appropriate civil penalties under [42 U. S. C. §§ 6928(a) and (g)].” 42 U.S. C. § 6972(a).
A State is a “citizen” under the CWA and a “person” under RCRA,9 and is thus entitled to sue under these provisions.
Ohio and its amici argue that by specifying the United States as an entity subject to suit and incorporating the civil-*617penalties sections of the CWA and RCRA into their respective citizen-suit sections, “Congress could not avoid noticing that its literal language subjected] federal entities to penalties.” Brief for Respondent Ohio 36; see also, e. g., Brief for National Governors’ Association et al. as Amici Curiae 14-16. It is undisputed that each civil-penalties provision authorizes fines of the punitive sort.
The effect of incorporating each statute’s civil-penalties section into its respective citizen-suit section is not, however, as clear as Ohio claims. The incorporations must be read as encompassing all the terms of the penalty provisions, including their limitations, see, e. g., Engel v. Davenport, 271 U. S. 33, 38 (1926) (adoption of earlier statute by reference “makes it as much a part of the later act as though it had been incorporated at full length”); see also 2B N. Singer, Sutherland on Statutory Construction §51.08 (5th rev. ed. 1992), and significant limitations for present purposes result from restricting the applicability of the civil-penalties sections to “person[sJ.”10 While both the CWA and RCRA define “person” to cover States, subdivisions of States, municipalities, and interstate bodies (and RCRA even extends the term to cover governmental corporations),11 neither statute defines “person” to include the United States.12 Its omission has to be *618seen as a pointed one when so many other governmental entities are specified, see 2A Singer, supra, §47.23, a fact that renders the civil-penalties sections inapplicable to the United States.
Against this reasoning, Ohio argues that the incorporated penalty provisions’ exclusion of the United States is overridden by the National Government’s express inclusion as a “person” by each of the citizen-suit sections. There is, of course, a plausibility to the argument. Whether that plausibility suffices for the clarity required to waive sovereign immunity is, nonetheless, an issue we need not decide, for the force of Ohio’s argument wanes when we look beyond the citizen-suit sections to the full texts of the respective statutes.
What we find elsewhere in each statute are various provisions specially defining “person” and doing so expressly for purposes of the entire section in which the term occurs. Thus, for example, “[f]or the purpose of this [CWA] section,” 33 U. S. C. § 1321(a)(7) defines “person” in such a way as to exclude the various governmental entities included in the general definition of “person” in 33 U. S. C. § 1362(5).13 Again, “[f]or the purpose of this section,” § 1322(a)(8) defines “person” so as to exclude “an individual .on board a public vessel” as well as the governmental entities falling within the general definition. Similarly in RCRA, “[f]or the purpose of. . . subchapter [IX]” the general definition of “person” is expanded to include “the United States Government,” among other entities. 42 U. S. C. §6991(6). Within each statute, then, there is a contrast between drafting that merely redefines “person” when it occurs within a particular clause or sentence and drafting that expressly alters the definition for any and all purposes of the entire section in *619which the special definition occurs.14 Such differences in treatment within a given statutory text are reasonably understood to reflect differences in meaning intended, see 2A Singer, supra, §46.06, and the inference can only be that a special definition not described as being for purposes of the “section” or “subchapter” in which it occurs was intended to have the more limited application to its own clause or sentence alone. Thus, in the instances before us here, the inclusion of the United States as a “person” must go to the clauses subjecting the United States to suit, but no further.
This textual analysis passes the test of giving effect to all the language of the citizen-suit sections. Those sections’ incorporations of their respective statutes’ civil-penalties sections will have the effect of authorizing punitive fines when a polluter other than the United States is brought to court by a citizen, while the sections’ explicit authorizations for suits against the United States will likewise be effective, since those sections concededly authorize coercive sanctions against the National Government.15
A clear and unequivocal waiver of anything more cannot be found; a broader waiver may not be inferred, see Ruckels-*620haus, 463 U. S., at 685-686. Ohio’s reading is therefore to be rejected. See United States v. Nordic Village, Inc., ante, 37.
B
The relevant portion of the CWA’s federal-facilities section provides that
“[e]ach department, agency, or instrumentality of the . . . Federal Government . . . shall be subject to, and comply with, all Federal, State, interstate, and local requirements, administrative authority, and process and sanctions respecting the control and abatement of water pollution in the same manner ... as any nongovernmental entity .... The preceding sentence shall apply (A) to any requirement whether substantive or procedural (including any recordkeeping or reporting requirement, any requirement respecting permits and any other requirement, whatsoever), (B) to the exercise of any Federal, State or local administrative authority, and (C) to any process and sanction, whether enforced in Federal, State, or local courts or in any other manner. . . . [T]he United States shall be liable only for those civil penalties arising under Federal law or imposed by a State or local court to enforce an order or the process of such court.” 33 U. S. C. § 1323(a).
Ohio rests its argument for waiver as to punitive fines on-two propositions: first, that the statute’s use of the'word “sanction” must be understood to encompass such fines, see Brief for Respondent Ohio 26-29; and, second, with respect to the fines authorized under a state permit program approved by EPA, that they “aris[e] under Federal law” despite their genesis in state statutes, and are thus within the scope of the “civil penalties” covered by the congressional waiver, id., at 29-35.
*621■ A
Ohio’s first proposition is mistaken. As a general matter, the meaning of “sanction” is spacious enough to cover not only what we have called punitive fines, but coercive ones as well, and use of the term carries no necessary implication that a reference to punitive fines is intended. One of the two dictionaries Ohio itself cites reflects this breadth. See Black’s Law Dictionary 1341 (6th ed. 1990) (defining “sanction” as a “[p]enalty or other mechanism of enforcement used to provide incentives for obedience with the law or with rules and regulations. That part of a law which is designed to secure enforcement by imposing a penalty for its violation or offering a reward for its observance”). Ohio’s other such source explicitly adopts the coercive sense of the term. See Ballentine’s Law Dictionary 1137 (3d ed. 1969) (defining sanction in part as “[a] coercive measure”).
Beyond the dictionaries, examples of usage in the coercive sense abound. See, e. g., Penfield Co. of Cal. v. SEC, 330 U. S. 585, 590 (1947) (fines and imprisonment imposed as “coercive sanctions” when imposed to compel target “to do what the law made it his duty to do”); Hicks v. Feiock, 485 U. S. 624, 633-634, n. 6 (1988) (“sanction” in Penfield was civil because it was conditional; contemnor could avoid “sanction” by agreeing to comply with discovery order); Fed. Rule Civ. Proc. 37(b) (describing as “sanctions” various steps district court may take in response to noncompliance with discovery orders, including holding recalcitrant deponent in contempt); United States v. Westinghouse Elec. Corp., 648 F. 2d 642, 649 (CA9 1981) (discussing “sanctions,” imposed pursuant to Fed. Rule Civ. Proc. 37(b), consisting of fine for each day litigant remained in noncompliance with District Court’s discovery order); Latrobe Steel Co. v. United Steelworkers of America, Local 1537, 545 F. 2d 1336, 1344 (CA3 1976) (“Coercive sanctions ... look to the future and are designed to aid the plaintiff by bringing a defiant party into compliance with the *622court order or by assuring that a potentially contumacious party adheres to an injunction by setting forth in advance the penalties the court will impose if the party deviates from the path of obedience”); Vincent v. Preiser, 175 W. Va. 797, 803, 338 S. E. 2d 398, 403 (1985) (discussing contempt “sanctions” imposed “to compel compliance with a court order”); Maltaman v. State Bar of Cal., 43 Cal. 3d 924, 936, 741 P. 2d 185, 189-190 (1987) (describing as “sanctions” daily fine imposed on party until it complied with order directing it to transfer certain property); Labor Relations Comm’n v. Fall River Educators’ Assn., 382 Mass. 465, 475-476, 416 N. E. 2d 1340, 1347 (1981) (affirming propriety of imposition of “coercive contempt sanction”); Cal. Civ. Proc. Code Ann. § 2023(b)(4) (West Supp. 1992) (authorizing, in response to litigant’s failure to obey discovery order, “terminating sanction^],” including “contempt sanction^] ” and orders staying further proceedings by recalcitrant litigant). Cf. 42 U. S. C. §6992e(a) (waiving federal medical-waste disposal facilities’ sovereign immunity from various requirements, including such “sanctions as may be imposed by a court to enforce [injunctive] relief”); id., §6961 (using same language to waive other federal facilities’ immunity from RCRA provisions). Thus, resort to a “sanction” carries no necessary implication of the punitive as against the coercive.
The term’s context, of course, may supply a clarity that the term lacks in isolation, see, e. g., Shell Oil Co. v. Iowa Dept. of Revenue, 488 U. S. 19, 26 (1988). It tends to do so here, but once again the clarity so found cuts against Ohio’s position. The word “sanction” appears twice in § 1323(a), each time within the phrase “process and sanction[s].” The first sentence subjects Government agencies to “process and sanctions,” while the second explains that the Government’s corresponding liability extends to “any process and sanction, whether enforced in Federal, State, or local courts or in any other manner.”
*623Three features of this context are significant. The first is the separate statutory recognition of three manifestations of governmental power to which the United States is subjected: substantive and procedural requirements; administrative authority; and “process and sanctions,” whether “enforced” in courts or otherwise. Substantive requirements are thus distinguished from judicial process, even though each might require the same conduct, as when a statute requires and a court orders a polluter to refrain from discharging without a permit. The second noteworthy feature is the conjunction of “sanction[s]” not with the substantive “requirements,” but with “process,” in each of the two instances in which “sanction” appears. “Process” normally refers to the procedure and mechanics of adjudication and the enforcement of decrees or orders that the adjudicatory process finally provides. The third feature to note is the statute’s reference to “process and sanctions” as “enforced” in courts or otherwise. Whereas we commonly understand that “requirements” may be enforced 'either by backward-looking penalties for past violations or by the “process” of forward-looking orders enjoining future violations, such forward-looking orders themselves are characteristically given teeth by equity’s traditional coercive sanctions for contempt: fines and bodily commitment imposed pending compliance or agreement to comply. The very fact, then, that the text speaks of sanctions in the context of enforcing “process” as distinct from substantive “requirements” is a good reason to infer that Congress was using “sanction” in its coercive sense, to the exclusion of punitive fines.
2
The last relevant passage of § 1323(a), which provides that “the United States shall be liable only for those civil penalties arising under Federal law or imposed by a State or local court to enforce an order or the process of such court,” is not to the contrary. While this proviso is unlike the preceding *624text in that it speaks of “civil penalties,” not “sanctions,” it is obviously phrased to clarify or limit the waiver preceding it. Here our concern is with its clarifying function (leaving its limiting effect until later), and it must be said that as a clarifier the proviso speaks with an uncertain voice. To be sure, the second modifier of “civil penalties” at least makes it plain that the term (like “sanction,” to which it relates) must include a coercive penalty, since “civil penalties” are exemplified by those “imposed by a State or local court to enforce an order or the process of such court.” To this extent, then, the proviso serves to confirm the reading we reached above.
The role of the first modifier is problematical, however. On the one hand, it tugs toward a more expansive reading of “civil penalties.” If by using the phrase “civil penalties arising under Federal law” Congress meant nothing more than coercive fines arising under federal law, it would have been simpler to describe all such penalties as imposed to enforce an order or process, whether of a local, state, or federal court. Thus, the first modifier suggests that the civil penalties arising under federal law may indeed include the punitive along with the coercive. Nevertheless, a reading expansive enough to reflect a waiver as to punitive fines would raise a new and troublesome question about the source of legal authority to impose such a fine. As far as federal law is concerned, the only available source of authority to impose punitive fines is the civil-penalties section, § 1319(d). But, as we have already seen, that section does not authorize liability against the United States, since it applies only against “persons,” from whom the United States is excluded.
Ohio urges us to find a source of authority good against the United States by reading “arising under Federal law” to include penalties prescribed by state statutes approved by EPA and supplanting the CWA. Ohio argues for treating a state statute as providing penalties “arising under Federal law” by stressing the complementary relationship between *625the relevant state and federal statutes and the role of such state statutes in accomplishing the purpose of the CWA. This purpose, as Ohio states it, is “to encourage compliance with comprehensive, federally approved water pollution programs while shielding federal agencies from unauthorized penalties.” Brief for Respondent Ohio 34-35. Ohio asserts that “federal facility compliance . . . cannot be . . . accomplished without the [punitive] penalty deterrent.” Id., at 35.
The case for such pessimism is not, however, self-evident. To be sure, an agency of the Government may break the law where it might have complied voluntarily if it had faced the prospect of punitive fines for past violations. But to say that its “compliance cannot be . . . accomplished” without such fines is to assume that without sanctions for past conduct a federal polluter can never be brought into future compliance, that an agency of the National Government would defy an injunction backed by coercive fines and even a threat of personal commitment. The position seems also to ignore the fact that once such fines start running they can be every dollar as onerous as their punitive counterparts; it could be a very expensive mistake to plan on ignoring the law indefinitely on the assumption that contumacy would be cheap.
Nor does the complementary relationship between state and federal law support Ohio’s claim that state-law fines thereby “arise under Federal law.” Plain language aside, the far more compelling interpretative case rests on the best known statutory use of the phrase “arising under federal law,” appearing in the grant of federal-question jurisdiction to the courts of the United States. See 28 U. S. C. § 1331. There, we have read the phrase “arising under” federal law to exclude cases in which the plaintiff relies on state law, even when the State’s exercise of power in the particular circumstances is expressly permitted by federal law. See, e. g., Gully v. First Nat. Bank in Meridian, 299 U. S. 109, 116 (1936) (suit over state taxation of nationally chartered bank does not arise under federal law even though such taxa*626tion would not be possible without federal approval); International Bridge Co. v. New York, 254 U. S. 126, 133 (1920) (congressional approval of construction of bridge by state-chartered company does not make federal law the source of right to build bridge).16 Congress’ use of the same language in § 1323(a) indicates a likely adoption of our prior interpretation of that language. See, e. g., ICC v. Locomotive Engineers, 482 U. S. 270, 284-285 (1987) (interpreting statute based on previous interpretation of same language in another statute); Northcross v. Memphis Bd. of Education, 412 U. S. 427, 428 (1973) (per curiam) (similarity of language in two statutes “strong indication that [they] should be interpreted pari passu”). The probability is. enough to answer Ohio’s argument that “arising under Federal law” in § 1323(a) is broad enough to cover provisions of state statutes approved by a federal agency but nevertheless applicable ex proprio vigore.
Since Ohio’s argument for treating state-penalty provisions as arising under federal law thus fails, our reading of the last-quoted sentence from § 1323(a) leaves us with an unanswered question and an unresolved tension between closely related statutory provisions. The question is still what Congress could have meant in using a seemingly expansive phrase like “civil penalties arising under Federal law.” Perhaps it used it just in case some later amendment might waive the Government’s immunity from punitive sanctions . Perhaps a drafter mistakenly thought that liability for such sanctions had somehow been waived already. Perhaps *627someone was careless. The question has no satisfactory answer.
We do, however, have a response satisfactory for sovereign immunity purposes to the tension between a proviso suggesting an apparently expansive but uncertain waiver and its antecedent text that evinces a narrower waiver with greater clarity. For under our rules that tension is resolved by the requirement that any statement of waiver be unequivocal: as against the clear waiver for coercive fines the indication of a waiver as to those that are punitive is less certain. The rule of narrow construction therefore takes the waiver no further than the coercive variety.
C
We consider, finally, the federal-facilities section of RCRA, which provides, in relevant part, that the National Government
“shall be subject to, and comply with, all Federal, State, interstate, and local requirements, both substantive and procedural (including any requirement for permits or reporting or any provisions for injunctive relief and such sanctions as may be imposed by a court to enforce such relief) ... in the same manner, and to the same extent, as any person is subject to such requirements- Neither the United States, nor any agent, employee, or officer thereof, shall be immune or exempt from any process or sanction of any State or Federal Court with respect to the enforcement of any such injunctive relief.” 42 U.S. C. §6961.
Ohio and its amici stress the statutory subjection of federal facilities to “all . . . requirements,” which they would have us read as an explicit and unambiguous waiver of federal sovereign immunity from punitive fines. We, however, agree with the Tenth Circuit that “all... requirements” “can reasonably be interpreted as including substantive standards and the means for implementing those standards, but exclud*628ing punitive measures.” Mitzelfelt v. Department of Air Force, 903 F. 2d 1293, 1295 (1990).
We have already observed that substantive requirements can be enforced either punitively or coercively, and the Tenth Circuit’s understanding that Congress intended the latter finds strong support in the textual indications of the kinds of requirements meant to bind the Government. Significantly, all of them refer either to mechanisms requiring review for substantive compliance (permit and reporting requirements) or to mechanisms for enforcing substantive compliance in the future (injunctive relief and sanctions to enforce it). In stark contrast, the statute makes no mention of any mechanism for penalizing past violations, and this absence of any example of punitive fines is powerful evidence that Congress had no intent to subject the United States to an enforcement mechanism that could deplete the federal fisc regardless of a responsible officer’s willingness and capacity to comply in the future.
The drafters’ silence on the subject of punitive sanctions becomes virtually audible after one reads the provision’s final sentence, waiving immunity “from any process or sanction of any State or Federal Court with respect to the enforcement of any such injunctive relief.” The fact that the drafters’ only specific reference to an enforcement mechanism described “sanction” as a coercive means of injunctive enforcement bars any inference that a waiver of immunity from “requirements” somehow unquestionably extends to punitive fines that are never so much as mentioned.17
*629III
The judgment of the Court of Appeals is reversed, and the eases are remanded for further proceedings consistent with this opinion.

It is so ordered.

 The parties agreed to stay one claim pending completion of a technical study. See Stipulation Between DOE and Ohio, App. 87-88.

 DOE's water-pollution permit was issued by EPA. See Complaint ¶ 29. DOE had no RCRA permit at the time Ohio commenced this suit, despite RCRA’s requirement that facilities such as DOE’s Fernald plant obtain one. See Complaint ¶¶ 50, 52, 57; Answer of Federal Defendants ¶ 57.

 33 U. S. C. § 1323(a) (CWA); 42 U. S. C. §6961 (RCRA). The federal-facilities sections of the CWA and RCRA govern the extent to which federally operated facilities, such as DOE’s Fernald facility, are subject to the requirements, including fines, of both their respective statutes and EPA-approved, state-law regulation and enforcement programs.

 33 U. S. C. § 1365(a) (CWA); 42 U. S. C. § 6972(a) (RCRA). The citizen-suit sections of the CWA and RCRA authorize private enforcement of the provisions of their respective statutes. Unlike the waivers in the federal-facilities sections, which set forth the scope of federal sovereign immunity from the requirements, including fines, of both their respective statutes and EPA-approved, state-law regulation and enforcement programs, the citizen-suit sections, to the extent they waive federal immunity at all, waive such immunity only from federal-law penalties.
States may sue the United States under the citizen-suit sections. See 33 U. S. C. § 1365(a) (any “citizen” may bring citizen suit under CWA); id., § 1365(g) (defining “citizen” for purposes of CWA citizen-suit section as “person . . . having an interest which is or may be adversely affected”); id., § 1362(5) (defining “person” for purposes of CWA to include a State); 42 U. S. C. § 6972 (“any person” may bring citizen suit under RCRA); id., § 6903(15) (“person” for purposes- of RCRA includes a State).

 The court held that its ruling on the CWA’s federal-facilities section obviated any need to consider that statute’s citizen-suit section. 904 F. 2d, at 1062.

 Ohio’s petition also asked that if we reversed the' lower court’s conclusion on the CWA’s federal-facilities section, we consider whether that statute’s citizen-suit section contained a waiver, an issue the Sixth Circuit declined to reach.

 The Sixth Circuit’s holding that the CWA’s federal-facilities section waives federal sovereign immunity from punitive fines conflicts with the Ninth Circuit’s conclusion that that section does not constitute such a waiver. See California v. Department of Navy, 845 F. 2d 222 (1988). One Court of Appeals has found such a waiver in the CWA’s citizen-suit section. See Sierra Club v. Lujan, 931 F. 2d 1421 (CA10 1991). Two other Courts of Appeals agree with the Sixth Circuit that RCRA’s federal-facilities section does not waive federal sovereign immunity from punitive fines. See Mitzelfelt v. Department of Air Force, 903 F. 2d 1293 (CA10 1990); United States v. Washington, 872 F. 2d 874 (CA9 1989). No other *615Court of Appeals appears to have considered whether RCRA’s citizen-suit section constitutes such a waiver.

 See n. 6, supra.

 See 33 U. S. C. § 1319(d) (CWA civil-penalties section); 42 U. S. C. §§ 6928(a), (g) (RCRA civil-penalties sections).

 See 33 U. S. C. § 1362(5) (defining “person” for purposes of CWA as “an individual, corporation, partnership, association, State, municipality, commission, or political subdivision of a State, or any interstate body”); 42 U. S. C. § 6903(15) (defining “person” for purposes of RCRA as “an individual, trust, firm, joint stock company, corporation (including a government corporation), partnership, association, State, municipality, commission, political subdivision of a State, or any. interstate body”).

 A subsection of RCRA dealing'with a federal demonstration program tracking the disposal of medical waste does in fact require that “each department, agency, and instrumentality of the United States” “be treated as” a “person.” See Medical Waste Tracking Act of 1988, §2(a), Pub. L. 100-582, 102 Stat. 2955, 42 U. S. C. §6992e(b). This broader provision, *618however, applies only “[f]or purposes of this Act,” ibid., which refers to the Medical Waste Tracking Act of 1988 itself, see 102 Stat. 2950.

 See n. 11, supra.

 The dissent fails to appreciate this difference, arguing that § 1365(a) “states that any person, as used in that subdivision, includes the United States,” post, at 633. That statement is simply incorrect; the citizen-suit section does no more than include the United States in the class of entities that may be the subject of a suit brought under this section. In stark contrast to the examples we have given, see n. 12, supra, § 1365(a) does not purport to apply the more expansive definition of “person” throughout the subsection; by its terms it speaks only to the first mention of “person.”

 DOE explicitly concedes that such relief is available against the United States in the context of citizen suits pursuant to the CWA, see Brief for Petitioner DOE 33, and implicitly so concedes with regard to RCRA, see id., at 40-41. DOE also concedes that both statutes’ federal-facilities sections authorize imposition of injunctive-type relief against the National Government, see id., at 19-20, and n. 10; see also id., at 35. DOE concedes federal liability to such penalties without reference to the civil-penalties sections of the CWA or RCRA.

 Of course, the phrase “arising under” federal law appears in Article III, § 2, of the Constitution, where it has received a broader construction than in its statutory counterpart. See Verlinden B. V. v. Central Bank of Nigeria, 461 U. S. 480, 494-496 (1983). Ohio, however, has offered no reason to believe Congress intended this broader reading rather than the narrower statutory reading. Even assuming an equal likelihood for each intent, our rule requiring a narrow construction of waiver language tips the balance in favor of the narrow reading.

 We also reject Ohio’s argument purporting to rest on Hancock v. Train, 426 U. S. 167 (1976). In Hancock we determined that, as then written, § 118 of the Clean Air Act, 42 U. S. C. § 1857f (1970 ed.), did not require federal facilities to obtain state pollution permits as a condition of continued operation. The relevant portion of § 1867 required the National Government to “comply with Federal, State, interstate, and local requirements respecting control ... of air pollution.” Ohio and its amici stress the point in our analysis where we found it significant that §1857 did not require federal compliance with “all federal, state, interstate, and local *629requirements,” or with “all requirements of the applicable state implementation plan.” See 426 U. S., at 182 (emphasis in original). They read our opinion as drawing a distinction between substantive and procedural requirements, and as interpreting § 1867 as not waiving federal immunity from procedural requirements, the group in which we classified the state permit programs. Ohio and its amici conclude that the drafters of RCRA took our observations in Hancock to heart, and, seeking to waive federal sovereign immunity for all purposes, including liability for civil punitive fines, waived immunity for “all . . . requirements, both substantive and procedural.” 42 U. S. C. § 6961; see Brief for Respondent Ohio 41; see also, e. g., Brief for State of California et al. as Amici Curiae 21.
The answer to this is twofold. Indications of the breadth of the Government’s obligation to comply with substantive or procedural requirements dealt with in Hancock do not necessarily translate into indications that the Government’s subjection to mechanisms for enforcing those obligations extends to punitive as well as to coercive sanctions. In any event, if Congress had in fact entertained the intention Ohio suggests, it would hardly have avoided any example of punitive fines at the same time as it expressly mentioned the coercive injunctive remedy.
