Opinion for the Court filed by Circuit Judge GRIFFITH.
The Secretary of the Interior has interpreted the phrase “valid existing rights” in the Surface Mining Control and Reclamation Act to foreclose surface mining operations in sensitive areas. The National Mining Association challenges this reading of the statute, but we conclude that we must defer to the Secretary’s reasonable interpretation of this ambiguous phrase.
I.
In 1977, Congress enacted the Surface Mining Control and Reclamation Act (“SMCRA”), 30 U.S.C. §§ 1201 et seg., “to *705 protect society and the environment from the adverse effects of surface coal mining operations,” id. § 1202(a). Section 522(b) of the SMCRA authorizes the Secretary of the Interior (“Secretary”) to prohibit surface coal mining operations on federal lands if he determines them to be unsuitable for that purpose. Id. § 1272(b). Section 522(e) bans outright surface mining in statutorily designated areas. 1 Id. § 1272(e). In this appeal, we are asked to determine how Congress intended that ban to work. The relevant text of § 522(e) provides: “After August 3, 1977, and subject to valid existing rights no surface coal mining operations except those which exist on August 3, 1977, shall be permitted [in the statutorily designated areas].” Id. (emphasis added).
Because one must show “valid existing rights” (“VER”) to start a surface mining operation in a § 522(e) area, the meaning of the phrase is critical. For decades, the Secretary and the courts have wrestled with how best to understand VER and determine what it protects. We need not recount this history. Suffice it to say that VER has occasioned a spectrum of agency interpretations, ranging from a relaxed “ownership and authority” standard, which required only that the miner show a property right in the coal, to a more exacting “all permits” standard, which called for a showing that surface mining licenses had been issued prior to the date § 522(e) took effect. See Valid Existing Rights, 64 Fed. Reg. 70,766, 70,769-71 (Dec. 17, 1999) (recounting Secretary’s prior definitions of VER).
In 1999, the Secretary and the Office of Surface Mining Reclamation and Enforcement promulgated a rule through notice- and-comment procedures offering yet another interpretation of VER. Id. at 70,831-32 (codified at 30 C.F.R. § 761.5). This “1999 Rule,” as we will call it, was a setback for parties hoping to conduct new surface mining operations in § 522(e) areas. Under the 1999 Rule, a miner claiming VER protection must satisfy two conditions. First, he must produce a legally binding document that vested him with the right to mine the land at the time it came under § 522(e). Second, he must either prove that the owner of the land, by the time it came under § 522(e), had made a good faith effort to obtain all necessary permits for the mining, or else prove that the coal is immediately adjacent to a surface mining operation in existence on August 3, 1977 and is needed to ensure the economic viability of the mining operation as a whole. The Secretary prefaced this interpretation of VER with a 72-page preamble describing the agency’s long relationship with the phrase, explaining the rationale for the latest interpretation, and responding to objections raised during the notice-and-comment period. Significantly, the preamble acknowledges that the chosen VER interpretation protects 3,062 more acres than the least restrictive alternative and predicts that “few persons will qualify for VER under this standard.” Valid Existing Rights, 64 Fed.Reg. 70, 766, 70, 776, 70, 778 (Dec. 17,1999).

This case begins with an unusual question created by a mistake in the language of the jurisdictional grant. We have an “independent obligation to determine whether subject-matter jurisdiction exists,”
Arbaugh v. Y & H Corp.,
The district court claimed jurisdiction under 30 U.S.C. § 1276(a)(1), which renders “[a]ny action by the Secretary promulgating national rules or regulations ... subject to judicial review in the United States District Court for the District of Columbia Circuit.” But there is no such court within the federal judiciary. The judgment the NMA has asked us to review comes from a court called “the United States District Court for the District of Columbia.”

Nat’l Mining Ass’n v. Fowler,
The NMA urges that Congress inserted VER in § 522(e) to protect mineral owners’ property rights. As the NMA tells it, VER allows surface mining by those with a property right to mine coal. Were this true, the Secretary’s restrictive interpretation of VER in the 1999 Rule would violate a congressional directive, and we would be required to set it aside. But we do not read the statute so narrowly. Since 1977, VER has been interpreted by five different Administrations, each of which has found within its borders the room to establish a preferred policy, The NMA takes this history to mean that the agency’s current policy is entitled to less deference because it has changed over time, but the opposite is true. That Congress presented so wide a range of plausible interpretations to an agency with rule-making authority shows a delegation to the executive branch of the power to make reasonable adjustments to the nation’s surface mining policy.
A.
Our
Chevron
analysis begins with asking whether Congress has delegated authority to an agency by leaving a statutory gap for the agency to fill.
The major source of VER’s ambiguity is the word “rights.” The NMA, reaching for its dictionary, notes that the word “right” could be taken to mean “property right.” See Appellant’s Br. at 34 (interpreting “rights” to mean “‘an interest or title in an object of property’ ”) (quoting Black’s Law Dictionary 1324 (6th ed.1990)); see also Blace’s Law DICTIONARY 1347 (8th ed.2004) (defining “right” as, inter alia, an “interest, claim, or ownership that one has in tangible or intangible property”). But according to the same dictionary on which the NMA relies, this is not the only meaning the word will bear. Blace’s Law Dictionary 1324 (6th ed.1990) (defining “right” as, inter alia, “[a] legally enforceable claim of one person against another, that the other shall do a given act, or shall not do a given act”); see also Black’s Law Dictionary 1347 (8th ed.2004) (defining “right” as, inter alia, “[a] legally enforceable claim that another will do or will not do a given act”). In fact, this definition cuts against the NMA’s proposed interpretation of VER because it is not tied in all circumstances to property.
Just as “right” can function as a proxy for property rights, it will also do service more generally.
See, e.g., id.
(“[sjome-thing that is due to a person by just claim, legal guarantee, or moral principle”); 13 The Oxford English Dictionary 923 (2d ed.1989) (“[jjustifiable claim, on moral or legal grounds, to have or obtain something, or to act in a certain way”); Webster’s New International Dictionary 2147 (2d ed.1952) (“[tjhat to which one has a just claim”). Under
Chevron,
we ask “whether Congress has directly spoken to the precise question at issue.”
VER could be read, as the NMA suggests, as protecting “valid existing
property
rights.” But it could also encompass a narrower protection, as in the 1999 Rule. Nothing in § 522(e) suggests Congress intended to enact the former understanding over the latter. This case is thus the reverse of
Friends of the Earth, Inc. v. EPA,
Of course, not every statutory ambiguity gives rise to agency prerogative.
See Gonzales v. Oregon,
B.
Having satisfied ourselves that VER is ambiguous, we defer to the Secretary’s interpretation of the phrase if it “is based on a permissible construction of the statute.”
Chevron,
The 1999 Rule remains true to the authority delegated to the Secretary in the SMCRA by protecting against the harmful effects of surface mining that Congress sought to ameliorate. Providing this protection is the primary aim of the statute. See 30 U.S.C. § 1201(e) (declaring that regulation of surface coal mining “is an appropriate and necessary means to minimize so far as practicable the adverse social, economic, and environmental effects of such mining operations”); id. § 1201(c), (k) (warning of deleterious effects of surface coal mining); id. § 1202(a) (stating that a purpose of the SMCRA is to “establish a nationwide program to protect society and the environment from the adverse effects of surface coal mining operations”); id. § 1202(f) (stating that a purpose of the SMCRA is to “strike a balance between protection of the environment ... and the Nation’s need for coal as an essential source of energy”). Therefore it is not surprising that the Secretary has promulgated an interpretive rule that cuts against the interests of some miners.
The NMA’s suggestion that the SMCRA effected robust protection of miners’ property rights is belied by the way Congress used the word “property” in that statute. Of the twenty-nine instances in which “property” appears, only one refers to protecting the property rights of subsurface owners of the mineral estate. Id. § 1304(g) (concerning coal owned by the United States). Many uses of “property” concern the protection of surface or adjacent property owners against the harmful effects of surface mining, id. §§ 1201(c), 1233(a)(1)(A), 1239(a), 1253(a)(15)(C), 1253(a)(17), 1257(f), 1269(a), 1270(f), 1272(a)(3)(D), 1307(b), and several mentions of “property” run counter to miners’ property rights, in that they authorize government entry onto mined property to assess and remedy environmental degradation caused by strip mining, id. §§ 1237(a), 1237(b), 1240(b).
Save for repeating its argument that VER is unambiguous and accusing the Secretary of “flip-flopping,” Appellant’s Br. at 53, the NMA provides little resistance on this front.

With the exception of the constitutional avoidance argument, discussed next, the NMA offers no basis for finding the Secretary’s interpretation unreasonable. If that argument fails, we must accord
Chevron
deference to the 1999 Rule.
See Consumer Elees. Ass’n v. FCC,
The NMA asserts that the 1999 Rule runs afoul of both the Due Process and Takings Clauses of the Fifth Amendment, an argument raised to invoke the canon of constitutional avoidance. Because the judiciary must rightly presume that Congress acts consistent with its duty to uphold the Constitution, courts make every effort to construe statutes so as to find their constitutional foundations and thus avoid needless constitutional confrontations.
See Edward J. DeBartolo Corp. v. Fla. Gulf Coast Bldg. & Constr. Trades Council,
Though its briefs are unclear, the NMA appears to argue that its procedural due process rights were violated because the 1999 Rule created no mechanism by which miners could comply with the good-faith permitting requirement had they not already done so by August 3, 1977. The NMA argues that
United States v. Locke,
The NMA also argues that the 1999 Rule precludes
Chevron
deference by working a taking of subsurface coal interests. A taking, however, is only unconstitutional if the government fails to pay just compensation, and the Tucker Act provides for such a remedy.
See
28 U.S.C. § 1491(a). Miners can pursue their takings claims in the United States Court of Federal Claims (“Claims Court”). Given this protection, the NMA’s takings challenge raises no serious question about the 1999 Rule that would preclude
Chevron
deference.
See United States v. Riverside Bayview Homes,
This is not to say that the canon of constitutional avoidance can be ignored with respect to every argument sounding in the Takings Clause. The Supreme Court has recognized that the Claims Court is not a proper venue if a statute creates “an identifiable class of cases in which application of [the] statute will necessarily constitute a taking.”

The district court properly accorded Chevron deference to the Secretary’s interpretative rule. The judgment is
Affirmed.

. Subject to certain exceptions, § 522(e) designates the following areas: lands within the National Park System, the National Wildlife Refuge Systems, the National System of Trails, the National Wilderness Preservation System, the Wild and Scenic Rivers System; federal lands within a national forest; areas that would adversely affect public parks or places included in the National Register of Historic Sites; areas within one hundred feet of the outside right-of-way line of any public road; and areas within three hundred feet of any occupied dwelling, public building, school, church, community, or institutional building, or within one hundred feet of a cemetery. See 30 U.S.C. § 1272(e).

See Nat'l Wildlife Fed’n v. Hodel,
. Academic commentary supports our reading of VER. We note that the Journal of Mineral Law & Policy, a publication of the University of Kentucky College of Law, dedicated an entire issue to analysis of VER as used in the SMCRA. See generally Valid Existing Rights Symposium, 5 J. Min. L. & Pol'y 381 et seq. (1990). Despite devoting 375 pages to the topic, the symposium participants reached no consensus on VER’s meaning. As stated by Professor Laitos, in whom the NMA’s briefing places great faith: "Typically, Congress never lists what interests it means to include within the 'valid existing rights' phrase. The task of interpretation thus falls on the executive branch (i.e., the Department of Interior) or the courts.” Jan G. Laitos & Richard A. Westfall, Government Interference with Private Interests in Public Resources, 11 Harv. Envtl. L.Rev. 1, 19 (1987). Of course, we cannot outsource the task of statutory interpretation to the professoriate, but we find it illuminating that scholars with expertise in this area have been similarly unable to distill a single, clear meaning from VER.
