Opinion for the Court filed by Circuit Judge RANDOLPH.
These are four consolidated cases on appeal from the judgment of the district court sustaining regulations of the National Park Service governing concession contracts in the National Park System. Many of the issues are tied to the history of the National Park System and the functions concessioners perform in the operation of the parks.
The history begins with the discovery of “Old Faithful” and the other natural wonders of what is now Yellowstone National Park. In 1872, Congress withdrew the land at the headwaters of the Yellowstone River from “settlement, occupancy, or sale,” thus creating the first national park in the United States. Act of Mar. 1, 1872, *821 ch. 24, § 1, 17 Stat. 32. See also AubRey L. Haines, Yellowstone National Park Its Exploration and Establishment (1974). Not everyone had been enthusiastic about the plan to create Yellowstone National Park. A local newspaper editorial worried that “the effect of this measure will be to keep the country a wilderness, and shut out, for many years, the travel that would seek that curious region if good roads were opened through it and hotels built therein.” Haines, supra, at 127 (quoting the Helena Daily HeRAld of Mar. 1,1872). In the final legislation, Congress responded by authorizing the Secretary of the Interi- or to lease portions of the park for “the erection of buildings for the accommodation of visitors.” 17 Stat. 33.
As the United States withdrew more areas from the public domain, it continued to favor the interests of park visitors. In creating the National Park Service in 1916, Congress authorized the Interior Secretary to “grant privileges, leases, and permits for the use of land for the accommodation of visitors” to each of the “various parks, monuments, or other reservations” under the Secretary’s authority. An Act to Establish a National Park Service, ch. 408, 39 Stat. 595 (1916). In the view of the first director of the Park Service, Stephen Mather: “Scenery is a hollow enjoyment to a tourist who sets out in the morning after an indigestible breakfast and a fitful sleep in an impossible bed.” Dennis J. Herman, Loving Them to Death: Legal Controls on the Type and Scale of Development in the National Parks, 11 Stan. Envtl. L.J. 3, 3 (1992).
During its first thirty years, the Park Service followed internal regulations and policies governing concessioners and their obligations to park visitors and to the national park lands. The government also offered financial inducements to private contractors to convince them to provide and operate facilities in what were often remote locations. See Park Concession Policy: Hearings Before the Subcomm. on National Parks of the House Comm, on Interior and Insular Affairs, 88th Cong. 5-8 (1964) [hereinafter Park Concession Policy Hearings] (letter from John A. Carver, Jr., Assistant Secretary of the Interi- or).
For our purposes the most significant of these incentives was a preferential right of renewal, which “contemplated that every existing contract covering public operations [in the national parks] will be renewed at the expiration thereof, provided, of course, that full and satisfactory service to the public had been given thereunder.” Memorandum for the Acting Under Secretary, U.S. Department of the Interior (Aug. 10, 1940). When the Interior Department sought to change its policies and withdraw some of these financial incentives in the late 1940s, the concessioners and some in Congress balked.
See
H.R. Res. 66, 81st Cong. (1950), passed by the Comm, on Public Lands and included in H.R.Rep. No. 81-3133, at 5-6 (1950). In response, the Secretary announced new guidelines for concession contracts and preserved many of the existing financial incentives for concessioners, including the preferential right of renewal.
Id.
at 4-5. The House Committee on Public Lands passed a resolution endorsing these new guidelines, although the resolution of course had no legal effect.
INS v. Chadha,
By the 1960s, other House committees started expressing doubt about the soundness of the Interior Department’s contracting policies, particularly the financial incentives it was giving concessioners. See House Comm, on Government Operations, Survey of Selected Activities, H.R.Rep. No. 88-306, pt. 3, at 4-12 (1963) (“The committee’s inquiry disclosed considerable *822 weakness in the National Park Service’s operations in several matters involving concessioners in the national parks.”). When Congress considered the 2964 appropriations bill for the Department of the Interior, the House Committee on Appropriations recommended that “competitive bidding should be required for concession contracts, in lieu of the current practice of granting preferential opportunities to existing concessioners to negotiate new contracts.” Department of the InteRioe and Related Agenoies Appropriation Bill, H.R.Rep. No. 88-177, at 10 (1963).
Concerned that “certain other committees that do not have jurisdiction” had “attempted to get into the problem of concessions,” the House Committee on Interi- or and Insular Affairs produced a bill to “put into statutory form” the longstanding concessions policies of the Park Service, including the preferential right of renewal. H.R.Rep. No. 89-591, at 1 (1965); Park Concession Policy Hearings at 19. In 1965, these concession policies were enacted into law. See 111 Cong. Reo. 23,632-48 (1965). Part of the legislation provided that the “Secretary [of the Interior] shall ... giv[e] preference in the renewal of contracts or permits and in the negotiation of new contracts or permits to the conces-sioners who have performed their obligations ... to the satisfaction of the Secretary.” National Park Service Concessions Policy Act, Pub.L. No. 89-249, § 5, 79 Stat. 969, 970 (1965), repealed by National Parks Omnibus Management Act of 1998, Pub.L. No. 105-391, § 415(a), 112 Stat. 3497, 3515. The preference gave “incumbent concessioners, upon renewal, the right to meet any better offer received” by the Park Service. U.S. Dep’t of the Interior, Report of the Task; Force on National Park Servioe Conoessions 10 (1990).
The 1965 Act governed all concession contracts entered into by the Park Service. Concessioners paid the government a franchise fee, typically less than five percent of gross revenues, for the privilege of operating on federal land. If they used government-owned facilities they paid an additional fee.
In 1998, after several aborted attempts, Congress repealed the preferential right of renewal and enacted other rules governing concession contracts. National Parks Omnibus Management Act of 1998, 16 U.S.C. §§ 5951-5966.
Plaintiffs are three companies who have current concessions contracts with the Park Service and an association of conces-sioners. They brought four separate actions challenging the Park Service regulations, issued in 2000, to implement the 1998 Act. 65 Fed.Reg. 20,630 (Apr. 17, 2000) (to be codified at 36 C.F.R. pt. 51). The district court consolidated the four lawsuits, and granted summary judgment to the government on all of the claims save one (which has not been appealed to this court).
Amfac Resorts v. United States Dep’t of the Interior,
I.
The first issue centers on the 1998 Act’s repeal of the statutory preferential right of renewal in § 5 of the 1965 Act. The 1998 Act provided that, except for small contracts and outfitter and guide services, “the Secretary shall not grant a conces-sioner a preferential right to renew a concessions contract.” 16 U.S.C. § 5952(7). A savings clause in the 1998 Act, § 415(a), states: “repeal of [the 1965 Act] shall not affect the validity of any concessions contract or permit entered into under such Act, but the provisions of this title shall apply to any such contract or permit except to the extent such provisions are inconsistent with the terms and conditions of any such contract or permit.” Pub.L. No. *823 105-391, § 415(a), 112 Stat. 3497, 3515 (1998).
The Park Service interpreted the repealing and the savings clauses in the following narrative regulation:
§ 51.102 What is the effect of the 1998 Act’s repeal of the 1965 Act’s preference in renewal?
(a) Section 5 of the 1965 Act required the Secretary to give existing satisfactory concessioners a preference in the renewal (termed a “renewal preference” in the rest of this section) of its concession contract or permit. Section 415 of the 1998 Act repealed this statutory renewal preference as of November 13, 1998. It is the final decision of the Director, subject to the right of appeal set forth in paragraph (b) of this section, that holders of 1965 Act concession contracts are not entitled to be given a renewal preference with respect to such contracts (although they may otherwise qualify for a right of preference regarding such contracts under Sections 403(7) and (8) of the 1998 Act as implemented in this part). However, if a concessioner holds an existing 1965 Act concession contract and the contract makes express reference to a renewal preference, the con-cessioner may appeal to the Director for recognition of a renewal preference.
(b) Such appeal must be in writing and be received by the Director no later than thirty days after the issuance of a prospectus for a concession contract under this part for which the concessioner asserts a renewal preference. The Director must make a decision on the appeal prior to the proposal submission date specified in the prospectus. Where applicable, the Director will give notice of this appeal to all potential offerors that requested a prospectus. The Director may delegate consideration of such appeals only to a Deputy or Associate Director. The deciding official must prepare a written decision on the appeal, taking into account the content of the appeal and other available information,
(c)If the appeal results in a determination by the Director that the 1965 Act concession contract in question makes express reference to a renewal preference under section 5 of the 1965 Act, the 1998 Act’s repeal of section 5 of the 1965 Act was inconsistent with the terms and conditions of the concession contract, and that the holder of the concession contract in these circumstances is entitled to a renewal preference by operation of law, the Director will permit the concessioner to exercise a renewal preference for the contract subject to and in accordance with the otherwise applicable right of preference terms and conditions of this part, including, without limitation, the requirement for submission of a responsive proposal pursuant to the terms of an applicable prospectus. The Director, similarly, will permit any holder of a 1965 Act concession contract that a court of competent jurisdiction determines in a final order is entitled to a renewal preference, for any reason, to exercise a right of preference in accordance with the otherwise applicable requirements of this part, including, without limitation, the requirement for submission of a responsive proposal pursuant to the terms of an applicable prospectus.
36 C.F.R. § 51.102 (2001).
The Park Service thus will not recognize a preferential right of renewal for conces-sioners whose pre-1998 contracts are expiring, unless the contract expressly so provides. See 65 Fed.Reg. at 20,631-33. In the language of the savings clause of § 415(a), without such contractual “terms and conditions” it would not be “inconsistent”' — as the Park Service sees it — to re *824 fuse to allow a preferential right of renewal.
A typical concession contract runs for 15 or 20 years. Repokt of the Task FoRce on National Park Service Concessions, supra, at 5. One of the plaintiffs, Amfac Resorts, L.L.C., had a 30-year contract for the Grand Canyon. A right of renewal for pre-1998 contracts is therefore a matter of great interest to those holding these contracts. The concessioners say that the renewal provision of the 1965 Act represented an “entrenched policy”; that the policy was incorporated by law as an unwritten term in every concession contract signed between 1965 and 1998; and that the Park Service regulation violates § 415 of the 1998 Act (the savings clause) because it allows a preferential right of renewal only if contracts before the 1998 Act expressly so state.
A.
The concessioners’ argument in favor of an “implied” right of renewal initially rests on the
“Christian
doctrine,” named after
G.L. Christian & Assocs. v. United States,
The Federal Circuit has, on occasion, concluded that certain statutory or regulatory provisions may become part of a government contract even though the contract does not contain language to that effect.
See S.J. Amoroso Constr. Co. v. United States,
Our court has never adopted the Federal Circuit’s
Christian
doctrine. Even if we did so, it would boot the con-cessioners nothing. In describing the doctrine, they have omitted a crucial element. The Federal Circuit does not hold that significant or important federal policies “form part of government contracts even where absent from those contracts’ explicit text.” Brief for Appellants at 22. If that were the law, Congressional power to make adjustments in legislation would be greatly constricted. Statutory provisions would live on as part of long-term contracts well after their repeal or modification. This is why, as the Supreme Court put it in
Dodge v. Board of Education,
One element of the
Christian
doctrine, the element missing from the concessioners’ statement of the law, saves it
*825
from contradicting this line of Supreme Court authority. According to the Federal Circuit, it is not enough that the legislative or regulatory provision is important or significant (assuming one could make such rankings). To constitute a contractual obligation even though not written in the contract, the provision must be a mandatory contract clause, a clause the legislation — or as in
Christian,
The renewal provision contained in § 5 of the 1965 Act was by no stretch a mandatory contract term. The Secretary’s contracting authority was derived from a different part of the 1965 Act — § 3, which authorized the Secretary to “include in contracts” such “terms and conditions as, in his judgment, are required to assure the concessioner of adequate protection against loss of investment ... resulting from discretionary acts, policies, or decisions of the Secretary occurring after the contract has become effective.... ” § 3, 79 Stat. 969. Section 5 of the 1965 Act was of another sort. It stated that the Secretary “shall ... giv[e] preference in the renewal of contracts or permits.... ” § 5, 79 Stat. 970. Rather than leaving the matter to individual negotiations, § 5 required the Secretary to grant a right of renewal to all concessioners, regardless of the terms of their individual concession contracts. The provision thus constituted “legislation which merely declares a state policy, and directs a subordinate body to carry ■ it into effect.”
Dodge v. Bd. of Educ.,
It is possible that some parties nevertheless insisted on having a right of renewal written into their contracts and that the Secretary yielded. Possible, but not likely. The concessioners have identified no such contract and the Park Service is aware of none.
B.
Apart from the Christian doctrine, each of the concessioners maintains that the Park Service’s regulation is “facially invalid because [it denies] altogether the possibility of implied contractual rights in individual cases” and prevents “any concessioner in a future proceeding from offering specific evidence of a bargained-for and mutually-agreed upon contractual renewal right. If even one concessioner has such evidence, the regulations denying those rights across-the-board are unlawful.” Brief for Appellants at 26, 27. In other words, although the regulation is valid as applied to dozens of concession contracts, it is invalid because of the possibility that one concessioner might have an implied — that is, an unwritten — preferen *826 tial right of renewal. The argument, aimed at the validity of the regulation on its face, does not accurately state the law.
In
United States v. Salerno,
A facial challenge to a legislative Act is, of course, the most difficult challenge to mount successfully, since the challenger must establish that no set of circumstances exists under which the Act would be valid. The fact that the [statute] might operate unconstitutionally under some conceivable set of circumstances is insufficient to render it wholly invalid, since we have not recognized an “overbreadth” doctrine outside the limited context of the First Amendment.
Justice Stevens believes that only the second sentence of the
Salerno
excerpt states the governing principle for facial challenges. He and Justice Scalia have debated whether the first sentence from
Salerno
— what has become known as the “no-set-of-cireumstances” test — is instead controlling.
See City of Chicago v. Morales,
The facial attack on § 51.102 is not, of course, on the basis that the regulation is unconstitutional. The claim is that § 51.102 conflicts with § 415 of the 1998 Act. In
National Mining Ass’n v. Army Corps of Engineers,
Our examination of Supreme Court precedent in
National Mining
apparently overlooked
Reno v. Flores,
When an intervening Supreme Court decision alters the law of the circuit, a panel of our court must follow the Court’s decision in all later cases.
See, e.g., McKesson Corp. v. Islamic Republic of Iran, 52
F.3d 346, 350 (D.C.Cir.1995);
National Treasury Employees Union v. FLRA,
Either formulation — the no-set-of-circumstances test adopted from
Salerno
in
Reno v. Flores,
or the less strict
NCIR
standard — may pose potential problems for judicial review of agency regulations, especially in this circuit. Lacking a rule-making record containing evidence relating to the rule’s application to a particular entity, petitioners ordinarily mount -only facial attacks, often on the ground that the agency’s product conflicts with the statute. In such cases, the consequence of upholding the regulation because it is not invalid in all its applications
(Reno v.
Flores), or because it is invalid in only some of its applications
(NCIR),
may be that petitioners would have to make their challenge in another circuit and in another setting, in defense of an enforcement action for instance. Some of the statutes .governing jurisdiction prescribe a specific time period for judicial review of regulations, restrict venue to our circuit, and may prohibit review outside the time period, except in limited circumstances.
See, e.g.,
Clean Air Act, 42 U.S.C. § 7607(b); Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), 42 U.S.C. § 9613(a);
Adamo Wrecking Co. v. United States,
Whatever the outcome in such cases, the situation here is not comparable. Our circuit does not have exclusive jurisdiction over Park Service regulations, and judicial review is not confined to a particular time period. Nothing would preclude a conces-sioner from bringing an action for a declaratory judgment that the regulation, as applied to the concessioner, deprives it of a contractual right in violation of the savings clause. In fact, one of the consolidated actions in the district court was such a suit. Amfac’s complaint alleged that its 1969 contract for the Grand Canyon was about to expire, that the contract contained an implied preferential right of renewal arising “from the circumstances of the formation of the 1969 contract,” that the Park Service’s regulation denied the existence of such an implied term, and that the regulation as applied to Amfac therefore violated § 415 of the 1998 Act. Although § 51.102 may be valid on its face, this would not necessarily doom Amfac’s as-applied challenge.
With this in mind, we return to the concessioners’ assertion that if “even one concessioner has [evidence showing an implied right of renewal], the regulations denying those rights across-the-board are unlawful.” Brief for Appellants at 27. We do not need to choose between
Reno v. Flores
or
NCIR
to dispose of that contention. Not even First Amendment over-breadth analysis — which embodies a far more difficult standard for laws to satisfy than the one the Court formulated in
Salerno
— would render a law facially invalid because of the prospect of a single invalid application. An overbreadth attack will succeed only if the legislation is substantially overbroad' — 'that is, only if the law “reaches a substantial number of impermissible applications.”
New York v. Ferber,
Perhaps recognizing as much, the con-cessioners assert that
“some
contracts might
as a factual matter
include the [renewal] right as a bargained-for term,” a “possibility” (despite obstacles posed by the parol evidence rule and perhaps statutes of fraud) they think is enough to render the regulation unlawful. Brief for Appellants at 29. But far more is demanded before a regulation may be declared facially invalid. Under
Reno v. Flores,
§ 51.102 must of course be sustained on its face because there are circumstances in which applying the regulation would not be inconsistent with § 415 of the 1998 Act. The regulation’s requirement of an express contract term, for instance, properly eliminates claims of an implied renewal right based on the
Christian
doctrine alone. Even under the more relaxed standard of
NCIR,
it is not enough that
“some
contracts might
as a factual matter”
contain an implied renewal right. To repeat, that “the regulation may be invalid as applied in some cases, however, does not mean that the regulation is facially invalid because it is without statutory authority.”
NCIR,
In reaching this result we have followed a course different than that of the district court. We should explain why. The district court thought the “lawfulness of the defendants’ regulations turns on whether
*829
the plaintiffs each have a contractual right to preference renewal.”
This Contract [or permit] and the administration of it by the Secretary shall be subject to the laws of Congress governing the Area and rules, regulations and policies whether now in force or hereafter enacted or promulgated.
Id.
But that begs the question the conces-sioners posed here (and in the rulemaking,
see
Comments of the National Park Hospitality Ass’n at 23 (Oct. 14, 1999)). The savings clause of the 1998 Act is one of the “laws of Congress” to which this contractual provision refers. If a concessioner has an implied right of renewal in a pre-1998 contract, the savings clause preserves it. The Park Service does not deny the possibility of an implied contractual provision— that is, an unwritten one — in government contracts.
See

37 Stan. L.Rev. 1367 (1985). The district court, quoting
Hercules, Inc. v. United States,
*830
This still leaves the allegations in Amfac’s complaint that § 51.102 was inconsistent with the savings clause of the 1998 Act as applied to Amfac’s concession contract for the Grand Canyon. Complaint of Amfac Resorts at ¶ ¶ 21, 41. Amfac entered into that contract in 1969. The contract expired on December 31, 2001, after the district court’s judgment. Amfac turned out to be the only offeror and so the government argues that its as-applied challenge to the right-of-renewal regulation is moot: “Amfac can have no ‘preference’ for [the Park Service] to consider when there are no other offerors.” Brief for Appellees at 38. Even if Amfac eventually won the Grand Canyon contract, a subject about which we are not informed, we do not believe its as-applied challenge would necessarily be moot. Amfac argues that because § 51.102 threw its alleged implied renewal right in doubt, it “was forced to bid more generously for the Grand Canyon contract than it otherwise would have.” Reply Brief for Appellants at 16. If this assertion can be proven,
see Lujan v. Defenders of Wildlife,
Amfac can succeed in its claim that the regulation is invalid as-applied to its 1969 Grand Canyon contract only if it can prove the essential predicate — that the regulation, in contradiction to the savings clause of the 1998 Act, deprived it of a contractual right. Amfac therefore should be allowed to adduce proof of its alleged implied right of renewal and should be permitted reasonable discovery to this end. The district court refused to allow any discovery on the ground that judicial review of the regulation must be confined to the administrative record, except in limited circumstances not presented here.
We therefore reverse the district court’s grant of summary judgment on Amfac’s as-applied challenge to the prospectus for concessions at the Grand Canyon National Park. In doing so, we recognize that one of the claims of another plaintiff, Hamilton
*831
Stores, Inc., might be construed as an as applied challenge similar to that of Amfac. Complaint of Hamilton Stores, Inc. at ¶ 21. But the concessioners’ brief presents no argument to this effect; in fact, neither the concessioners’ brief nor their reply brief even mentions this portion of the Hamilton Stores complaint. We thus view the claim, which the district court rejected, as having been waived on appeal.
See, e.g., Doe v. Dist. of Columbia,
II.
A.
The 1998 Act, as did the 1965 Act, recognized that the United States owns all capital improvements constructed on federal land within the National Park System. 16 U.S.C. § 5954(d). Nonetheless, the 1998 Act gave concessioners a “leasehold surrender interest” in any “capital improvement” the concessioner “constructs” “pursuant to a concession contract.” 16 U.S.C. § 5954(a). The Act defines “capital improvement” as “a structure, fixture, or nonremovable equipment provided by a concessioner pursuant to the terms of a concession contract.” 16 U.S.C. § 5954(e). When the concession contract expires or is terminated, the incumbent is entitled to receive from its successor (or the government) the value of this interest. 16 U.S.C. § 5954(c). The amount of each concessioner’s “leasehold surrender interest”— or, as the parties call it, LSI — is “equal to the initial value (construction cost of the capital improvement), increased (or decreased)” by a percentage measured by the Consumer Price Index, less depreciation. 16 U.S.C. § 5954(a)(3). If the expiring concession contract is renewed, the concessioner’s LSI carries over. 16 U.S.C. § 5954(b).
The plaintiff-concessioners are unhappy with the Park Service’s regulations implementing these and other LSI provisions of the 1998 Act. They say that “ ‘capital improvement’ is a well-recognized technical accounting term that all companies, as a matter of financial reporting, tax accounting, and sound business practice use to distinguish upgrades to facilities from ordinary ‘repair and maintenance’ costs.” Brief for Appellants at 41. For support they cite an affidavit from an accountant submitted by Amfac in the district court. But the district court refused to consider, in this facial challenge, affidavits not submitted as part of the administrative record,
The concessioners also complain about § 51.67 of the regulations, 36 C.F.R. § 51.67, and the “Repair and Maintenance Reserve” in the Park Service’s “Standard Concession Contract,” 65 Fed.Reg. at 26,-069. Section 51.67 provides that concessioners do not earn LSI “for repair and maintenance of real property improvements unless a repair and maintenance project is a major rehabilitation.” “Major rehabilitation” is defined in 36 C.F.R. § 51.51 as a pre-approved “comprehensive rehabilitation” project the “construction cost of which exceeds fifty percent of the pre-rehabilitation value of the structure.” (The phrase “repair and maintenance” is not defined, in the regulations or in the 1998 Act.) The Standard Concession Contract requires concessioners to establish a reserve fund for repairs and maintenance projects, which “may include repair or replacement of foundations, building frames, window frames, sheathing, subfloors, drainage, rehabilitation of building systems such as electrical, plumbing, built-in heating and air conditioning, roof replacement and similar projects.” 65 Fed.Reg. at 26,069.
The concessioners object that § 51.67 allows LSI only for “projects costing more than 50% of a structure’s replacement costs....” 36 C.F.R. §51.67. What types of “projects” they do not say. If the project is a “capital improvement” it is added to the LSI no matter what the cost of construction.
See
The district court, after considering these arguments and others, thought it could not give a definitive answer to the issues thus posed. Echoing
Reno v. Flores,
B.
The concessioners have two other problems with the LSI regulations. The first relates to 16 U.S.C. § 5954(a)(3) and the valuation of LSI: each concessioner’s “leasehold surrender interest is equal to the initial value (construction cost of the capital improvement), increased (or decreased)” by a percentage measured by the Consumer Price Index, less depreciation. The implementing regulation, 36 C.F.R. § 51.51, defines “construction cost” as “the total of the incurred eligible direct and indirect costs necessary for constructing or installing the capital improvement .... ” “Eligible direct and indirect costs” are costs “in amounts no higher than those prevailing in the locality of the project,” id. It is this “locality” limitation to which the concessioners object. Projects in national parks, they tell us, are almost always more expensive to construct than “similar private projects in nearby localities, and Congress could not reasonably have intended that concessioners swallow such costs without LSI credit,” a point the Park Service does not dispute. Brief for Appellants at 47-48. But as the Park Service points out, the concessioners’ argument assumes that “locality” means outside the national park. The regulations do not so state and we see no basis for indulging in that assumption. It may be that the Park Service’s particular interpretation regarding a particular project in a particular national park could unreasonably limit the valuation of a concessioner’s LSI. But that is no reason to hold that the regulation conflicts with the statute or that it is arbitrary. If a concessioner has its own construction company, as some apparently do, nothing in the 1998 Act requires the Park Service to accept whatever amount the concessioner decides to *834 charge itself for the construction work. See 65 FecLReg. at 20,651. Like the district court, we therefore sustain the regulation.
The concessioners’ remaining problem with the LSI regulations deals with 16 U.S.C. § 5954(a)(5): if the concessioner “makes a capital improvement to an existing capital improvement in which the concessioner has a leasehold surrender interest, the cost of such additional capital improvement shall be added to the then current value of the concessioner’s leasehold surrender interest.” Their claim is that § 51.65 of the regulations conflicts with this provision. The regulation states:
A concessioner that replaces an existing fixture in which the concessioner has a leasehold surrender interest with a new fixture will increase its leasehold surrender interest by the amount of the construction cost of the replacement fixture less the construction cost of the replaced fixture.
36 C.F.R. § 51.65. This regulation is unlawful, according to the concessioners, because there is nothing in the statute allowing subtractions from a concessioner’s LSI. They also believe the calculations required by the regulation would be an administrative nuisance. In the Grand Canyon concession, for instance, there are about 300 structures with many thousands of fixtures.
The district court sustained the regulation for reasons given by the Park Service, reasons we also find persuasive. Without the regulation, concessioners would receive a windfall every time they removed a fixture and replaced it with a new one:
If a [concessioner] with a leasehold surrender interest in the hotel were to replace the hotel furnace once every five years for 15 years, the plaintiffs’ proposed accounting would be to increase the leasehold surrender interest three separate times by the cost of the furnace. Under this approach, the [conces-sioner] would hold a leasehold surrender interest equal to four furnaces, even though the hotel would only contain one.
III.
The concessioners claim the Park Service wrongly excluded concessions contracts from coverage under the Contract Disputes Act, 41 U.S.C. § 601 et seq. See 36 C.F.R. § 51.3; 65 Fed.Reg. at 20,635.
Enacted in 1978, the Contract Disputes Act provides an alternative forum for government contract disputes. Rather than seeking judicial relief in the Court of Federal Claims, a contractor may appeal decisions by a contracting official to an administrative board within that agency. 41 U.S.C. § 607. The board’s decision may be appealed to the U.S. Court of Appeals for the Federal Circuit. 41 U.S.C. § 607(g).
Section 51.3 of the regulations states that concession contracts are not “con

tracts” within the meaning of the Contract Disputes Act. 36 C.F.R. § 51.3 (2000). With this we agree. The Act applies to any “express or implied contract” for the “procurement” of “property,” “services” or “construction.” 41 U.S.C. § 602(a)(2). A procurement contract, the Park Service reasoned, “is a contract for which the government bargains for, and pays for, and receives goods and services.” 65 Fed.Reg. at 20,635. Concession contracts are not of that sort. Them function is not to procure services or goods for the government. Instead, as the Park Service put it, concession contracts “authorize third parties to provide services to park area visitors.”

While the Park Service does not administer the Contract Disputes Act, and thus may not have interpretative authority over its provisions, its reasoning finds support not only in the terms of that statute but also in the National Parks Omnibus Management Act of 1998, under which the Park Service may enter into concession contracts “to authorize a person, corporation or other entity to provide accommodations, facilities and services to visitors to” national parks. 16 U.S.C. § 5952. The Committee reports accompanying the 1998 Act also concluded that concession “contracts do not constitute contracts for the procurement of goods and services for the benefit of the government or otherwise,” S.Rep. No. 105-202, at 39 (1998); H.R.Rep. No. 105-767, at 43 (1998), a position the Park Service had reached earlier with respect to
concession
contracts under the 1965 Act.
See, e.g.,
Concessions Contracts and Permits, 57 Fed.Reg. 40,496, at 40,498 (Sept. 3, 1992) (reiterating that the Park Service “has never considered [concessions contracts] a type of federal procurement contract”). The Court of Federal Claims, considering the nature of concession contracts, also concluded that “this arrangement does not constitute, a procurement, but is a grant of a permit to operate a business.”
YRT Servs. Corp. v. United States,
As against this analysis, the concession-ers cite several decisions of the Interior Department Board of Contract Appeals [IBCA], a body created by Interior Department regulations,
see
41 U.S.C. § 607(a); 43 C.F.R. § 4.100
et seq.
(2000). The IBCA has held that the Contract Disputes Act applies to concession contracts.

The concessioners’ last complaint deals with the portion of the new regulations designed to deal with transactions involving corporate concessioners
(see
The concessioner may not assign, sell, convey, grant, contract for, or otherwise transfer (such transactions collectively referred to as “assignments” for purposes of this part), without the prior written approval of the Director, any of the following:
(a) Any concession contract;
(c) Any controlling interest in a con-cessioner or concession contract;
36 C.F.R. § 51.85(a) & (c). A similar regulation prohibits, without prior approval, any “encumbrance” of a “controlling interest in a concessioner.” 36 C.F.R. § 51.86(c). In the concessioners’ view, the regulations extend beyond the statute. The 1998 Act forbids any “concessions contract” from being “transferred, assigned, sold, or otherwise conveyed or pledged by a concessioner” without government approval. 16 U.S.C. § 5957(a). Approval must be given unless “the entity seeking to acquire a concessions contract is not qualified” or the transfer or conveyance would otherwise adversely affect performance of the contract in a manner specified in 16 U.S.C. § 5957(b). The crucial difference between the regulations and the statute, the concessioners say, is that the regulations require approval of transactions dealing not only with the transfers or assignments of concession contracts but also with changes in control of the concessioner. The Park Service responds that its change-of-control rule ensures that unqualified persons do not wind up holding concession contracts. Unlike individuals, a corporation can in effect transfer a concession contract by selling its stock to another entity. 65 Fed.Reg. at 20,661. As the Park Service sees it, the regulations are a permissible construction of the statutory phrase “otherwise conveyed or pledged,” an argument with which the district court agreed.
How the Park Service regulations will operate does not exactly leap from the pages of the Federal Register. It is easy enough to see that if X corporation wanted to sell all its assets, including its concession contract, it would first have to get approval of the Director of the Park Service. No one doubts that the regulation properly requires as much. The Park Service also believes that if the non-public X corporation structured the transaction as a sale of 100% of its stock instead of an asset sale, there would be no functional difference as far as the concession contract is concerned.
See Alarm Indus. Communications Comm. v. FCC,
Beyond these simple examples we enter a vale of ambiguity. Transactions of the sort just described are not the focus of the concessioners’ concern. Their problem is that the regulations — -as they read them— require Park Service approval of transac *837 tions undertaken by the concessioners’ “shareholders or their affiliates.” Brief for Appellants at 55. But do they? The shareholders of incorporated concessioners are typically not individuals but parent corporations. The Park Service reports that “many” of its concessioners “are corporations that hold a concession contract as their exclusive business activity” and that almost all of the largest concessioners are “wholly owned subsidiaries of larger corporations.” 65 Fed.Reg. at 20,661. One of the plaintiffs here, ARAMARK Sports and Entertainment Services, Inc., is a wholly-owned subsidiary of ARA-MARK/HMS Company, which is a wholly-owned subsidiary of ARAMARK Sports and Entertainment Group, Inc., which is a wholly-owned subsidiary of ARAMARK Corporation, which is listed on the New York Stock Exchange. Brief for Appellants at iv.
Wholly-owned means, in the case of incorporated subsidiaries, that the parent corporation holds all of the subsidiary corporation’s stock. What worries the con-cessioners is that transactions by the parent could potentially require Park Service approval if a change in control would result. But the regulations do not read that way. The critical provision is 36 C.F.R. § 51.8. It speaks only of sales, assignments, conveyances and so forth by the “concessioner.” The term “concessioner,” in regulatory parlance, “is an individual, corporation, or other legally recognized entity that duly holds a concession contract,” 36 C.F.R. § 51.3 — a definition that at least on its face encompasses only the subsidiary corporation, not the parent. It therefore appears that if the parent corporation engages in a sale-of-control transaction, this would not require approval because the concessioner — the subsidiary corporation — -would not be doing the selling. The attorneys for the Park Service say, in their brief, that the regulations do indeed cover transactions by the corporate concession-er’s parent company. Brief for Appellees at 53-54. But they do not parse the language of the regulations, and they point to nothing in the Park Service’s explanation of its regulations that goes so far. In fact, the Park Service justified its regulations on the basis that it would be “anomalous” if a “corporate concessioner” could sell “its stock to a new party (sale of a controlling interest)” without having to seek Park Service approval. 65 Fed.Reg. at 20,661. If, despite the language of the regulations, transactions at the parent level are also supposed to be covered, we are far from certain how the Park Service intends to implement its rules. An investor might begin purchasing stock of the parent corporation of a corporate-concessioner on the open market. Must the concessioner corporation go to the Park Service and ask for approval of the outsider’s purchases of the parent when the outsider’s percentage of the outstanding shares reaches some magic number? That makes no sense. Neither the concessioner corporation nor the parent corporation has any control over the purchaser. Perhaps this is why the regulation seems to speak only in terms of the concessioner selling its stock. If the regulations do not cover the transaction just mentioned, but do cover a sale of control by a parent corporation, the Park Service would have to justify a rule that allows an outsider, a complete stranger, to gain a “controlling interest” through open market purchases but requires approval before the parent makes a block sale to the same person. Control of the parent, and thus of the subsidiary concessioner, would transfer in both situations, and under the Park Service’s theory, so would the concession contract, yet the one transaction would be regulated and the other not.
The short of the matter is that we do not know whether the problems the conces-sioners identify exist. We cannot be sure that the Park Service will apply its sale-of-
*838
control regulations to transactions involving only sales of stock
by
corporate conces-sioners (as distinguished from open market sales by shareholders or sales by a parent company of its stock). The questions thus raised, and the other questions posed by the many possible forms of corporate restructuring (see,
e.g.,
1 MaRtin D. GinsbuRG & Jack S. Levin, Mergers, Acquisitions, AND Buyouts ¶ 105 (2001)), present “too many imponderables” to permit judicial review at this time.
Clean Air Implementation Project v. EPA,
The possible hardship to the concession-ers in waiting does not alter our conclusion that the issues are not ripe. No conces-sioner has indicated that a transfer of control is imminent. We therefore have no reason to believe that in the immediate future they will have to alter their conduct to their disadvantage.
Contrast Abbott Labs.,
Our conclusion that this aspect of the case is not ripe differs from that of the district court, which ruled against the con-cessioners’ claim on its merits. We therefore vacate the district court’s judgment in this respect.
The judgment of the district court is affirmed in part, reversed in part and vacated in part. The case is remanded for further proceedings, consistent with this opinion, on Amfac’s as-applied challenge to regulations concerning the preferential right of renewal.
So ordered.
