OPINION OF THE COURT
BECKER, Circuit Judge.Plaintiff-appellant Swin Resource Systems, Inc. (“Swin”) owns and operates a solid waste processing facility in Hemlock Township, Columbia County, Pennsylvania. Defendant-appellee Lycoming County (“Ly-coming”), a Pennsylvania county, operates a landfill in Brady Township, in Lycoming. The case at bar arises from Lycoming’s decision to charge a lower rate for the reception and disposal of waste generated within Lycoming and nearby counties than for waste generated outside that area. In its complaint filed in the Middle District of Pennsylvania, Swin contended that this price difference violated the commerce clause by impermissibly interfering with and discriminating against interstate commerce, denied Swin equal protection of the laws and due process of law, violated a federal land leasing statute (43 U.S.C. § 931c (1982)), and constituted a breach of contract. Named as defendants were Ly-coming and various county officials.
The defendants moved to dismiss pursuant to Fed.R.Civ.P. 12(b)(6). With respect to the commerce clause claim, the defendants asserted that the marketing practices of the county-operated landfill fall within the protection of the so-called market-participant doctrine and hence escape scrutiny under the commerce clause. With respect to the equal protection claim, the defendants asserted that Lycoming’s pricing scheme was rationally related to the legitimate purpose of presuming landfill capacity for local waste. With respect to the federal statutory claim, the defendants contended that the statute did not give rise to a private right of action.
The district court, in an opinion reported at 678 F.Supp. 1116 (M.D.Pa 1988), agreed with the position of defendants and held that Swin’s federal claims (both constitutional and statutory) failed to state a claim upon which relief can be granted. It therefore dismissed these claims pursuant to Fed.R.Civ.P. 12(b)(6). It also dismissed the pendent state breach of contract claim for want of jurisdiction. Swin then filed a motion under Fed.R.Civ.P. 59(e) to alter or amend the judgment and an alternative motion under Fed.R.Civ.P. 62(c) for an injunction pending appeal. Swin did not seek leave by this motion or otherwise to amend *247its complaint in order to present additional facts or theories in support of its claims. Swin did, however, attach to its motion papers a deposition of a county employee associated with the initiation and operation of the landfill supplying additional factual data.
The district court denied Swin’s motions, and Swin appealed from the district court’s order refusing to alter or amend the judgment. A timely appeal from a denial of a Rule 59 motion to alter or amend the judgment also “ ‘brings up the underlying judgment for review.’ ” Federal Kemper Insurance Co. v. Rauscher, 807 F.2d 345, 348 (3d Cir.1986) (citation omitted).
In deciding (and reviewing) a motion to dismiss for failure to state a claim upon which relief can be granted, a court must accept as true the factual allegations in the complaint and all reasonable inferences that can be drawn therefrom. The complaint may be dismissed “only if it is certain that no relief could be granted under any set of facts that could be proved consistent with the allegations.” Hishon v. King & Spalding, 467 U.S. 69, 73, 104 S.Ct. 2229, 2232, 81 L.Ed.2d 59 (1984). Facts contained in the deposition that Swin submitted must not be considered if they fall outside the ambit of the complaint. See Biesenbach v. Guenther, 588 F.2d 400, 402 (3d Cir.1978). We will consider the facts stated in the deposition, to the extent that they fall within the ambit of the complaint, as illustrative of those facts which Swin could prove if its complaint were reinstated.
On appeal Swin has abandoned its due process and pendent state claims. We are therefore faced with three questions: (1) whether the marketing practices of the county-operated landfill fall within the market participant doctrine and hence escape scrutiny under the commerce clause; (2) whether these marketing practices violate the equal protection clause; and (3) whether the federal land leasing statute creates a private right of action in Swin’s favor. For the reasons that follow, we will affirm.
I. THE PLEADED FACTS
A. Swin’s Complaint
On June 5, 1973, the United States Bureau of Prisons granted a thirty-year permit to Lycoming to operate a public landfill on a 130-acre parcel on the federal prison reservation in Allenwood, Pennsylvania. The permit required Lycoming to pay all expenses associated with operating the landfill and to dispose of certain Bureau of Prisons waste without charge. In May 1974, Lycoming applied for and subsequently received a grant from the Appalachian Regional Commission in connection with the construction and operation of the landfill. The county opened the landfill in 1978 and has continued to operate it since that time through the Lycoming County Solid Waste Department.
Swin’s waste processing facility receives solid waste from Eastern Pennsylvania and New Jersey. Swin recycles some of the waste and sells it to businesses in several states. The remaining waste is compacted into bales and transported to landfills for disposal. Swin can produce 30 tons per hour of this baled solid waste and is presently producing an average of 300 tons per day.
On March 6, 1986, Lycoming notified Swin by letter that it would accept Swin’s baled solid waste for a price in the “range of” $10 per ton, promising to give Swin the exact price after the completion of a waste study within the next month. The letter also indicated that higher rates applied to waste generated outside an area comprised of Lycoming, Union, Snyder, Northumber-land, and Montour Counties and part of Columbia County, the other five counties being in the vicinity of Lycoming. Lycom-ing had apparently regarded Swin’s baled waste as originating from within the 5V2-county area, since from November 1986 to January 1987 it accepted Swin’s baled waste at the reduced rate. The landfill has sufficient capacity to serve the needs of both the 5V2-county area and Swin during the term of the thirty-year Bureau of Prisons lease.
Beginning in January 1987, however, and continuing until September 14, 1987, Ly-*248coming charged Swin $10 per ton for waste generated within Lycoming, $13.25 per ton for waste generated within the remaining counties of the 5V2-county area, and $17.20 per ton (less $1.50 for unloading) for waste generated outside the 5y2-county area. In March 1987, Lycoming instructed Swin to reduce the volume of waste it delivered to the landfill until a new field was “on line.” Swin accordingly reduced its deliveries to 100 tons per day. Because of this volume limitation, Swin was compelled to scale back its business operations substantially, as other waste disposal sites were scarce, more distant, and more costly.
Effective September 14, 1987, Lycoming raised the rate for solid waste originating outside the 5V2-county area to $30 per ton. Lycoming did not raise the $10 and $13.25 per ton rates for waste originating within the 5V2-county area. Lycoming charged Swin the $30 per ton rate and limited Swin indefinitely to delivering 100 tons per day. Under these conditions, Swin cannot economically use the Lycoming landfill, and it is no longer hauling waste there.
B. The Deposition Attached to Swin’s Post-Judgment Motions
Swin submitted the deposition of Jerry Walls, the longtime Executive Director of the Lycoming County Planning Commission, the functions of which include planning how Lycoming residents are to dispose of their solid waste. According to the deposition, Lycoming received $1.3 million from the Appalachian Regional Commission to assist Lycoming in the construction of the landfill.
Walls describes the recycling system Ly-coming has implemented to reduce the waste flow into the landfill. He testified that there were approximately nine to ten years of capacity left in the landfill. In addition, Walls describes the steps Lycom-ing took to ensure that enough municipalities used its landfill to enable Lycoming to pay back the landfill’s long-term indebtedness with user revenues. The Planning Commission developed a model municipal ordinance (subsequently adopted by a number of Lycoming municipalities) that permitted Lycoming to designate the landfill (or transfer station) to which a municipality’s waste haulers brought the waste they collected. Lycoming also entered into long-term disposal contracts with a number of municipalities.
II. THE COMMERCE CLAUSE CLAIM
The commerce clause grants Congress the power “[t]o regulate Commerce ... among the several States_” U.S.Const. Art. I, § 8, cl. 3. The Supreme Court, however, has long interpreted the clause to prohibit states from taking certain actions respecting interstate commerce even absent congressional action. See, e.g., Cooley v. Board of Wardens, 53 U.S. (12 How.) 299, 319 (1852). The commerce clause has been so construed in order to preserve “our national solidarity” by preventing the “rivalries and reprisals that were meant to be averted by subjecting commerce between the states to the power of the nation,” Baldwin v. G.A.F. Seelig, Inc., 294 U.S. 511, 522-23, 55 S.Ct. 497, 500, 79 L.Ed. 1032 (1935); to promote “[t]he material success that has come to inhabitants of the states which make up this federal free trade unit,” H.P. Hood & Sons, Inc. v. DuMond, 336 U.S. 525, 538, 69 S.Ct. 657, 665, 93 L.Ed. 865 (1949); and in recognition that “when the regulation is of such a character that its burden falls principally upon those without the state, legislative action is not likely to be subjected to those political restraints which are normally exerted on legislation where it affects adversely some interests within the state,” South Carolina State Highway Department v. Barnwell Brothers, Inc., 303 U.S. 177, 185 n. 2, 58 S.Ct. 510, 513 n. 2, 82 L.Ed. 734 (1938).
A. The Market Participant Doctrine
Swin contends that Lycoming’s attempt to preserve its landfill’s capacity for local residents by charging a higher price to dispose of distant waste in the landfill (and limiting the volume of distant waste accepted by the landfill) constitutes an impermissible interference with and discrimination against interstate commerce in *249violation of the commerce clause. The district court granted the defendants’ motion to dismiss the commerce clause claim on the ground that Lycoming had acted as a “market participant.” Under the market participant doctrine, a state or state subdivision that acts as a market participant rather than a market regulator “is not subject to the restraints of the Commerce Clause.” White v. Massachusetts Council of Construction Employers, Inc., 460 U.S. 204, 208, 103 S.Ct. 1042, 1045, 75 L.Ed.2d 1 (1983).
Application of the distinction between “market participant” and “market regulator” has, however, occasioned considerable dispute in the Supreme Court’s jurisprudence. The author of each of the three opinions that applied the doctrine—Hughes v. Alexandria Scrap Corp., 426 U.S. 794, 96 S.Ct. 2488, 49 L.Ed.2d 220 (1976) (Powell, J.); Reeves, Inc. v. Stake, 447 U.S. 429, 100 S.Ct. 2271, 65 L.Ed.2d 244 (1980) (Blackmun, J.); White, 460 U.S. 204, 103 S.Ct. 1042 (Rehnquist, J.)—authored a dissent in the next, the pattern being maintained by Justice Rehnquist’s dissent in South-Central Timber Development, Inc. v. Wunnicke, 467 U.S. 82, 101, 104 S.Ct. 2237, 2247-48, 81 L.Ed.2d 71 (1984), the principal case in which application of the doctrine resulted in a conclusion that the state was not a market participant. The Court has expressly reserved the question whether state operation of a landfill may fall within the market participant doctrine. See City of Philadelphia v. New Jersey, 437 U.S. 617, 627 n. 6, 98 S.Ct. 2531, n. 6, 57 L.Ed.2d 475 (1978).
For the reasons explained below, we hold that Lycoming County acted as a market participant rather than a market regulator in deciding the conditions under which Swin could use its landfill. It is useful to begin our analysis with a review of the four principal market participant cases.
In Alexandria Scrap, the Supreme Court upheld Maryland’s statutory scheme to rid the state of derelict automobiles, even though the scheme entailed two types of discrimination: (1) Maryland paid bounties to in-state scrap auto hulk processors while refusing to pay bounties to out-of-state processors on the same terms, and (2) Maryland paid bounties only for vehicles formerly titled in Maryland. 426 U.S. at 797, 801, 96 S.Ct. at 2493-94. The Court held that the statutory scheme was consistent with the commerce clause on the ground that Maryland was participating in the market rather than regulating it. Id. at 809-10, 96 S.Ct. at 2497-98. As the majority put it, “[njothing in the purposes animating the Commerce Clause prohibits a State, in the absence of congressional action, from participating in the market and exercising the right to favor its own citizens over others.” Id. at 810, 96 S.Ct. at 2498 (footnotes omitted).
In Reeves, the Court upheld a South Dakota policy of confining the sale of cement by a state-operated cement plant to residents of South Dakota in order to meet their demand during a “ ‘serious cement shortage.’ ” 447 U.S. at 432, 100 S.Ct. at 2275. The Court affirmed “[t]he basic distinction drawn in Alexandria Scrap between States as market participants and States as market regulators” and concluded that “South Dakota, as a seller of cement, unquestionably fits the ‘market participant’ label.” Id. at 436, 440, 100 S.Ct. at 2277, 2279. The Court upheld the South Dakota policy even though Reeves, a Wyoming corporation that had purchased about 95% of its cement from South Dakota’s state-operated plant for over twenty years, was forced to cut production by over 75% as a result of the policy. Id. at 433, 452 n. 4, 100 S.Ct. at 2286 n. 4.
In White, the Court, deeming the case “well within the scope of Alexandria Scrap and Reeves,” upheld an executive order of the Mayor of Boston requiring all construction projects funded in whole or in part either by city funds or city-administered federal funds to be performed by a work force of at least 50% city residents. 460 U.S. at 211 n. 7, 205 n. 1, 103 S.Ct. at 1046 n. 7, 1043 n. 1. Justice Blaekmun’s dissent emphasized that the city “ha[d] imposed as a condition of obtaining a public construction contract the requirement that private firms hire only Boston residents for 50% of specified jobs,” hence regulating *250whom private employers might hire. Id. at 217, 103 S.Ct. at 1049-50. Although the majority agreed that for the action to fall within the market participant doctrine there must be “some limits on a state or local government’s ability to impose restrictions that reach beyond the immediate parties with which the government transacts business,” it found it “unnecessary ... to define those limits with precision” as “[i]n this case ... [ejveryone affected by the order is, in a substantial if informal sense, ‘working for the city.’ ” Id. at 211 n. 7,103 S.Ct. at 1046 n. 7.
In Wunnicke, however, a plurality struck down Alaska’s requirement that timber taken from state lands be processed in-state prior to export. Adhering to the distinction suggested in White, the plurality held that “[t]he limit of the market-participant doctrine must be that it allows a State to impose burdens on commerce within the market in which it is a participant, but [does not] allow[ ] it to ... impose conditions, whether by statute, regulation, or contract, that have a substantial regulatory effect outside of that particular market.” 467 U.S. at 97, 104 S.Ct. at 2245. The Alaska policy crossed the line distinguishing participation from regulation because the conditions it attached to its timber sales amounted to “downstream regulation of the timber-processing market in which it is not a participant.” Id. at 99, 104 S.Ct. at 2246.
Application of the teaching of these four cases, with one caveat discussed below, readily leads us to the conclusion that Ly-coming County’s marketing of its landfill constitutes market participation rather than regulation. We see Lycoming as a market participant in the market for disposal services: the discrimination to which Swin objects is embodied only in rules concerning the price and volume conditions under which persons may use the disposal service that Lycoming itself offers. In setting these price and volume conditions, Ly-coming has not crossed the line that Alaska crossed when that state attempted to regulate the timber-processing market by conditioning its timber sales on guarantees that the purchasers would act in a certain way in a downstream market. The price and volume conditions to which Swin objects do not pertain to the operation of private landfills and do not apply beyond the immediate market in which Lycoming transacts business.
If Maryland may decree that only those with Maryland auto hulks will receive state bounties, it would seem that Lycoming can similarly decree that only local trash will be disposed of in its landfill on favorable terms. If South Dakota may give preference to local concrete buyers when a severe shortage makes that resource scarce, it would seem that Lycoming may similarly give preference to local garbage (and hence local garbage-producing residents) when a shortage of disposal sites makes landfills scarce.1 And if Boston may limit jobs to local residents, we see no reason why Ly-coming may not limit preferential use of its landfill to local garbage (and hence local garbage-producing residents).
Swin argues that Lycoming cannot be a market participant because the landfill is on federal government land and its start-up costs were paid for, in part, with federal funds. But the identity of Lycoming’s lessor is irrelevant, and a federal subsidy cannot distinguish Lycoming’s preference for local garbage from Boston’s hiring preference for jobs on construction projects funded by city-administered federal grant money.
Judge Gibbons states that “[t]here is no principled way to distinguish” the case at bar from Wunnicke because Lycoming’s restrictions on what garbage may be dumped in its landfill “affects” the “patterns of trade between concerns like Swin and its waste suppliers in New Jersey.” *251Diss. Op. at 259. With respect, Judge Gibbons reads Wunnicke too broadly. It does not hold that local governments will not be deemed market participants merely because of some incidental effect on trade. In Wunnicke, the state’s conditions on sales of state timber, by their own terms, set down rules as to what may be done with the timber with respect to activities quite distinct from the market transactions in which the state was engaged; in the case at bar, by contrast, Lycoming’s conditions on what garbage may be dumped in its landfill do not, by their own terms, regulate what may be done with the garbage outside of the market transactions in which Lycoming is engaged.
No court, to our knowledge, has ever suggested that the commerce clause requires city-operated garbage trucks to cross state lines in order to pick up the garbage generated by residents of other states. If a city may constitutionally limit its trucks to collecting garbage generated by city residents, we see no constitutional reason why a city cannot also limit a city-operated dump to garbage generated by city residents.2 With respect to municipal garbage trucks and municipal garbage dumps, application of the market participant doctrine enables “ ‘the people [acting through their local government] to determine as conditions demand ... what services and functions the public welfare requires.’ ” Reeves, 447 U.S. at 438 n. 11, 100 S.Ct. at 2278 n. 11 (quoting Helvering v. Gerhardt, 304 U.S. 405, 427, 58 S.Ct. 969, 978-79, 82 L.Ed. 1427 (1938) (Black, J., concurring)). The residents who reside within the jurisdiction of a county or municipality are unlikely to pay for local government services if they must bear the cost but the entire nation may receive the benefit.
Judge Gibbons reads Wunnicke as “suggesting that the limit of the market participant exception must at least be the ‘narrowly defined’ market in which the state participates.” Diss. Op. at 258. That test is met here. As we have already intimated, the distinction between market participant and market regulator is problematic, and Judge Gibbons’ arguments with respect to the difficulties of the market participant doctrine are not without force. We are satisfied, however, that within the existing Supreme Court eases, Lycoming clearly falls on the market participant side of the line.
B. Does a “Natural Resource” Exception Apply Here?
Swin’s vigorous argument that Lycoming has attempted to harbor a scarce natural resource for its own residents brings us to the potential caveat we mentioned. While the harboring of a scarce manufactured product or human service does not preclude the invocation of the market participant doctrine because it is scarce (in Reeves the Supreme Court applied the doctrine to South Dakota’s effort to harbor cement for its own residents despite a serious cement shortage), it may be that there is some special rule to be applied to a state’s effort to harbor a scarce natural resource. Unlike a manufactured product or the provision of a human service, a state does not have the ability to develop a natural resource if it has not had the fortuity to be favored with such a resource. While it may seem fair for South Dakota to favor its citizens in the sale of cement from *252a state-owned cement plant, for a state to favor its own citizens in selling rights to mine coal or limestone on state-owned lands, for example, or in selling state-owned coal or limestone, would seem less fair, especially if the state happened to be endowed with the bulk of our nation’s coal or limestone reserves and the other states were dependent upon it.
The Supreme Court has not squarely faced this issue, although it has noted its concern that a state’s endowment with a natural resource is a product of happenstance rather than hard work. In Reeves, the cement case, the Court noted that
[c]ement is not a natural resource, like coal, timber, wild game, or minerals. It is the end product of a complex process whereby a costly physical plant and human labor act on raw materials. South Dakota has not sought to limit access to the State’s limestone or other materials used to make cement_ Moreover, petitioner has not suggested that South Dakota possesses unique access to the materials needed to produce cement. Whatever limits might exist on a State’s ability to invoke the Alexandria Scrap exemption to hoard resources which by happenstance are found there, those limits do not apply here.
447 U.S. at 443-44, 100 S.Ct. at 2281 (emphasis added; citations and footnotes omitted).
Similarly, in Sporhase v. Nebraska, 458 U.S. 941, 102 S.Ct. 3456, 73 L.Ed.2d 1254 (1982), a case which upheld against a commerce clause challenge much of Nebraska’s scheme to control the sale of groundwater, the Court, citing Reeves, stated that “given [Nebraska’s water] conservation efforts, the continuing availability of ground water in Nebraska is not simply happenstance; the natural resource has some indicia of a good publicly produced and owned in which a State may favor its own citizens in times of shortage.” 458 U.S. at 957, 102 S.Ct. at 3464-65 (emphasis added). And in Wunnicke, the Alaska downstream timber regulation case, the Court noted in passing that an “element[ ] ... not present in Reeves ” but present in the Alaska case was the “involve[ment]” of a “natural resource.” 467 U.S. at 96, 104 S.Ct. at 2245. Cf. New England Power Co. v. New Hampshire, 455 U.S. 331, 338 n. 6, 102 S.Ct. 1096, 1100 n. 6, 71 L.Ed.2d 188 (1982) (characterizing Reeves as establishing that “a state may confine to its residents the sale of products it produces ” and refusing to characterize as market participation New Hampshire’s efforts to limit out-of-state sale of hydroelectric power generated by a privately owned power company from a river assert-edly owned by the state).
Interpreting the Supreme Court’s passing remarks as to the possible inapplicability of the market participant doctrine in a natural resource case is no easy task. The purported basis of the market participant doctrine is that “ ‘[n]othing in the purposes animating the Commerce Clause prohibits a State, in the absence of congressional action, from participating in the market and exercising the right to favor its own citizens over others.’ ” White, 460 U.S. at 207, 103 S.Ct. at 1044 (quoting Alexandria Scrap, 426 U.S. at 810, 96 S.Ct. at 2498 (footnotes omitted)). The Court in Reeves also quoted this sentence, emphasizing its “unmistakably broad terms.” 447 U.S. at 436, 100 S.Ct. at 2277. Hence, despite the Supreme Court’s dicta, excepting natural resources from the reach of the doctrine is inconsistent with the doctrine’s theoretical foundation, as a state selling a natural resource is “participating in the market.”
Whether there is a natural resource exception to the market participant doctrine is a difficult question, but, fortunately, one which we need not answer at this level of abstraction. First, land, the natural resource at issue here, cannot be used for a landfill without the expenditure of at least some money to prepare it for that purpose. The Lycoming landfill is therefore “not simply happenstance,” Sporhase, 458 U.S. at 957, 102 S.Ct. at 3464, but is at least to some extent like South Dakota’s cement plant in that government funds were needed to construct it. Moreover, since the land upon which the landfill was constructed had to be leased in this case, the land, even prior to development, bore some resemblance to South Dakota’s cement plant *253in that its devotion to public use required the disbursement or promise of future disbursement of government resources. Cf. Sporhase, 458 U.S. at 957, 102 S.Ct. at 3464 (In light of Nebraska’s conservation efforts, groundwater, a paradigmatic natural resource, “has some indicia of a good publicly produced and owned in which a State may favor its own citizens in times of shortage.”).
A second complication in relying upon a natural resource exception in the instant case flows from the idea that local benefits should follow local burdens, which the Supreme Court has relied upon in holding that state authorities can discriminate against out-of-state residents, even in cases involving a natural resource. See Sporhase, supra; cf. Baldwin v. Fish & Game Commission of Montana, 436 U.S. 371, 389-90, 98 S.Ct. 1852, 1863-64, 56 L.Ed.2d 354 (1978) (Montana law charging residents $9 and nonresidents $225 for an elk hunting license held not to violate equal protection because state devoted resources to elk conservation). Waste disposal is unlike some other natural resource industries in that few communities welcome the opening of a waste disposal site in their midst. The opening of the site is often viewed as a threat to property values and quality of life that is acceptable only because of the pressing need for waste disposal.3
A third complication is that categorizing a landfill as a “natural resource” simply because it is built on land proves too much. Since we can presume that South Dakota’s cement plant was built on land, the mere fact that a state uses land to participate in the market cannot by itself preclude it from relying on the market participant doctrine. A land-use natural resource exception to that doctrine, if there be one, must rest upon a more particularized inquiry. Rather than land in general, one might consider the natural resource to be land that is practicably available for the construction of a landfill. Such land could, presumably, be distinguished from land available for the construction of a cement plant through the introduction of evidence that land available for cement plants is plentiful and land available for landfills is scarce.
Although it would makes some sense (in light of the cement-plant-on-land problem) to distinguish between land in general and land practicably available for the construction of landfills, it would nevertheless be problematic to use such an availability figure to determine whether landfills constitute a natural resource. Shortages of land available for landfill construction may be created by vigorous local opposition to using geologically suitable land to build landfills or by a state’s hesitation, in light of the financial cost, to build landfills on geologically suitable land that it has already permitted to be dedicated to residential, commercial, industrial, or recreational use. To the extent that a shortage of landfill-*254available land is caused by such political factors, characterizing landfill-available land as being in short supply (and hence distinguishable from land available for cement plants) would seem inconsistent with a “happenstance” rationale for the natural resources exception to the market participant doctrine, as past and present political choices are not the product of geological happenstance.
In light of these considerations, we conclude that while there may be some place for a natural resource exception to the market participant doctrine, such an exception should not apply in the instant case. The present case is not one in which a state has “hoard[ed] resources which by happenstance are found there.” Reeves, 447 U.S. at 444, 100 S.Ct. at 2281. Rather, a state subdivision has used initiative to build a waste disposal facility to serve its needs. Furthermore, given Lycoming’s recycling program, one could say, as the Supreme Court did with respect to Nebraska’s water conservation program, that “the continuing availability of [the landfill] is not simply happenstance; the natural resource has some indicia of a good publicly produced and owned in which a State may favor its own citizens in times of shortage.” Sporhase, 458 U.S. at 957, 102 S.Ct. at 3464. We also take cognizance of the difficulties often attendant in efforts by municipalities to build waste disposal sites in light of their unpopularity with local residents. Neither the sacrifice of local residents in allowing a landfill to be built nearby nor the political character of much of the shortage of land available for landfill construction should be ignored.
This is not a case in which a state has hoarded a resource like coal or oil that is geologically peculiar to that state (although even with respect to such a natural resource, the Supreme Court has permitted states to exploit their monopoly position by exporting tax burdens to other states through facially neutral tax statutes, see, e.g., Commonwealth Edison Co. v. Montana, 453 U.S. 609, 619 & n. 8, 101 S.Ct. 2946, 2954 & n. 8, 69 L.Ed.2d 884 (1981)). Nor is this a case in which a state has used its ownership of land to discriminate against the transportation of goods in interstate commerce. Cf. Shell Oil Co. v. City of Santa Monica, 830 F.2d 1052 (9th Cir.1987) (city not a market participant where it assesses franchise fee on oil company seeking to build oil pipeline beneath city streets), cert. denied, — U.S. —, 108 S.Ct. 2901, 101 L.Ed.2d 934 (1988); Western Oil & Gas Association v. Cory, 726 F.2d 1340 (9th Cir.1984) (state not market participant in imposing fee for transportation of crude oil from offshore oil rigs across state-owned tidal and submerged lands), aff'd without opinion by an equally divided Court, 471 U.S. 81, 105 S.Ct. 1859, 85 L.Ed.2d 61 (1985). These right-of-way or transportation cases raise a discrete set of concerns, as open “channels of commerce ... are essential to the market itself” because they are “essential to [an outsider’s] ability to do business in the state.” Gergen, The Selfish State and the Market, 66 Tex.L.Rev. 1097, 1132-33 & n. 188 (1988).
C. Summary
The Supreme Court has repeatedly affirmed the principle that “[n]othing in the purposes animating the Commerce Clause prohibits a State, in the absence of congressional action, from participating in the market and exercising the right to favor its own citizens over others.” Alexandria Scrap, 426 U.S. at 810, 96 S.Ct. at 2498 (footnotes omitted). We are not persuaded that a county’s rules as to who may use its landfill are sufficiently suggestive of abuse of state power for us to depart from this principle. Other courts that have faced the issue whether public entities operating state landfills are market participants have come to the same conclusion.4 Because we *255conclude that under the pleaded facts Ly-coming has acted as a market regulator rather than a market participant, we will affirm the district court’s dismissal of Swin’s commerce clause claim.
Judge Gibbons would bypass our analysis in its entirety and hold that the Supreme Court effectively overruled the market participant doctrine cases in Garcia v. San Antonio Metropolitan Transit Authority, 469 U.S. 528, 105 S.Ct. 1005, 83 L.Ed.2d 1016 (1985). That Congress has a (virtually) absolute authority to enact legislation affecting the operation of state governments, as Garcia held, does not, however, imply that the federal courts should hold unconstitutional state action previously held constitutional as falling within the market participant doctrine. Garcia permits Congress to require state-operated landfills to accept out-of-state garbage on terms equal to those governing the acceptance of in-state garbage or to overturn the market participant doctrine in its entirety. Garcia does not require the Courts of Appeals to do so absent Congressional action.
And even if Judge Gibbons is correct in reasoning that Garcia undermined the logical basis for the market participant doctrine cases, we lack the authority to overrule them. “If a [Supreme Court] precedent ... has direct application in a case, yet appears to rest on reasons rejected in some other line of decisions, the Court of Appeals should follow the case which directly controls, leaving to [the Supreme Court] the prerogative of overruling its own decisions.” Rodriguez de Quijas v. Shearson/American Express, Inc., — U.S. —, 109 S.Ct. 1917, 1921-22, 104 L.Ed.2d 526 (1989).
III. THE EQUAL PROTECTION CLAIM
In light of Justice Stone’s insight that a state law principally harming those outside the state is unlikely to be subject to the political restraints normally brought to bear on laws adversely affecting those within the state, see South Carolina State Highway Department v. Barnwell Brothers, Inc., 303 U.S. 177, 184 n. 2, 58 S.Ct. 510, 513 n. 2, 82 L.Ed. 734 (1938), and his theory that courts should most carefully scrutinize the constitutionality of legislation harming those at a disadvantage in the political process, see United States v. Carotene Products Co., 304 U.S. 144, 152 n. 4, 58 S.Ct. 778, 783-84 n. 4, 82 L.Ed. 1234 (1938) (citing 303 U.S. at 184 n. 2, 58 S.Ct. at 513 n. 2), one might expect a high level of judicial solicitude for claims that a state or state subdivision has discriminated against out-of-state residents. The Supreme Court, however, has repeatedly held that a statute being challenged by those asserting such an equal protection claim, in a case “impinging upon no fundamental interest,” is to be reviewed under the rational basis standard that is normally used in matters of economic regulation. Alexandria Scrap, 426 U.S. at 813, 96 S.Ct. at 2499-2500. See, e.g., Northeast Bancorp, Inc. v. Board of Governors, 472 U.S. 159, 178, 105 S.Ct. 2545, 2555-56, 86 L.Ed.2d 112 (1985); Western & Southern Life Insurance Co. v. State Board of Equalization, 451 U.S. 648, 657, 101 S.Ct. 2070, 2077, 68 L.Ed.2d 514 (1981); Baldwin v. Fish & Game Commission of Montana, 436 U.S. 371, 391, 98 S.Ct. 1852, 1864, 56 L.Ed.2d 354 (1978).
The equal protection clause is satisfied, under this standard, as long as the legislature “rationally could have believed” that the statutory classification would promote a legitimate objective. Whether the statutory classification is “in fact” successful in accomplishing that objective is irrelevant. Western & Southern Life Insurance Co., 451 U.S. at 672, 101 S.Ct. at 2085 (emphasis omitted). States are “accorded wide lati*256tude in the regulation of their local economies under their police powers, and rational distinctions may be made with substantially less than mathematical exactitude.” City of New Orleans v. Dukes, 427 U.S. 297, 303, 96 S.Ct. 2513, 2517, 49 L.Ed.2d 511 (1976) (per curiam). A statutory classification “need not be drawn so as to fit with precision the legitimate purposes animating it.” Alexandria Scrap, 426 U.S. at 813, 96 S.Ct. at 2499. And economic legislation “ ‘carries with it a presumption of rationality that can only be overcome by a clear showing of arbitrariness and irrationality’ ” such that “ ‘the varying treatment of different groups ... is so unrelated to the achievement of any combination of legitimate purposes that we can only conclude that the legislature’s actions were irrational.’ ” Kadrmas v. Dickinson Public Schools, — U.S. —, 108 S.Ct. 2481, 2489, 101 L.Ed.2d 399 (1988) (citations omitted).
Swin argues that the asserted purpose of the disparate pricing scheme, to extend the useful life of the landfill to those within the Lycoming area, is illegitimate. We faced this issue in Hancock Industries v. Schaeffer, 811 F.2d 225 (3d Cir.1987), a case also involving a county’s efforts to exclude non-local waste as a means of preserving landfill capacity. We readily concluded that “providing for the continued disposal of ... County trash is a legitimate interest of the [County] Authority and would constitute a legitimate purpose for the exclusionary policy under [equal protection] attack.” 811 F.2d at 238. Countless cases have held that caring for local or regional needs is a legitimate purpose of local government. See, e.g., Northeast Bancorp, 472 U.S. at 177-78, 105 S.Ct. at 2555-56; Martinez v. Bynum, 461 U.S. 321, 328, 103 S.Ct. 1838, 1842, 75 L.Ed.2d 879 (1983); Western & Southern Life Insurance Co., 451 U.S. at 672, 101 S.Ct. at 2085; Alexandria Scrap, 426 U.S. at 814, 96 S.Ct. at 2500; Allied Stores of Ohio, Inc. v. Bowers, 358 U.S. 522, 528, 79 S.Ct. 437, 441-42, 3 L.Ed.2d 480 (1959).
Swin also argues that even if preserving landfill capacity for the residents of the Lycoming County area is a legitimate purpose, the pricing scheme is not rationally related to that purpose. We agree with the district court, however, that “[a]ny hole, no matter how large, can only accept a specific volume of garbage.” 678 F.Supp. at 1119. Charging higher prices for the disposal of distant garbage, thus reducing the flow of such garbage to the landfill, is manifestly related to the objective of preserving landfill capacity for local garbage. Our decision in Hancock is in accord with this view. See 811 F.2d at 238-39.
Lycoming’s pricing scheme is rationally related to the legitimate purpose of preserving the landfill for local waste-producing residents. No more is required. We will affirm the district court’s dismissal of Swin’s equal protection claim.
IV. THE 43 U.S.C. § 931c CLAIM
Swin contends that Lycoming has violated 43 U.S.C. § 931c (1982), which authorizes appropriate federal administrators to lease “public lands ... of the United States” to
States, counties, ... municipal corporations, or other public agencies for the purpose of constructing and maintaining on such lands public buildings or other public works. In the event such lands cease to be used for the purpose for which such permit, lease, or easement was granted, the same shall thereupon terminate.
43 U.S.C. § 931c (emphasis added). Swin argues that Lycoming’s restrictions on the use and cost of using the landfill deprive the landfill of its “public” character in violation of the statute. The threshold issue, however, is whether this statute creates a right of action permitting Swin to seek to enjoin its asserted violation.
Conceding that the statute does not contain an express right of action permitting it to sue, Swin contends that an implied right of action exists in its favor. In determining whether a federal statute that does not expressly provide for a particular private right of action nonetheless implicitly created that right, our task is one of statutory construction. The ultimate question in *257cases such as this is whether “Congress intended to create the private remedy ... that the plaintiff seeks to invoke.” Northwest Airlines, Inc. v. Transport Workers Union of America, 451 U.S. 77, 91, 101 S.Ct. 1571, 1580, 67 L.Ed.2d 750 (1981). “[U]nless this congressional intent can be inferred from the language of the statute, the statutory structure, or some other source, the essential predicate for implication of a private remedy simply does not exist.” Id. at 94, 101 S.Ct. at 1582.
Nothing in the language or statutory structure of this statute indicates that Congress intended private parties to be able to sue under the statute. Nor is there any indication that Swin is among the class for whose “especial benefit” the statute was enacted, a consideration which the Supreme Court has held important in deciding whether Congress intended to create a private right of action. See Cort v. Ash, 422 U.S. 66, 78, 95 S.Ct. 2080, 2087-88, 45 L.Ed.2d 26 (1975). The legislative history of the statute explains only that the legislation is
urgently needed to permit States and their local subdivisions to secure a tenure of use of sufficient duration to justify the expenditure of funds by State and local bodies for improvements of a permanent nature. Under present law some Federal agencies have no authority to issue long-term use permits, even to State and local public bodies. As a result local governmental units cannot afford to make substantial investments for improvements on such land with no guaranty of tenure, nor can they find a market for revenue bonds to finance the improvements.
H.R.Rep. No. 2243, 83rd Cong., 2d Sess. 1, reprinted in 1954 U.S.Code Cong. & Admin.News 3922, 3922. Nothing in the legislative history suggests that a private party in a position such as Swin has a right to sue under the statute. In light of these considerations, we conclude that Swin does not have a right of action under 43 U.S.C. § 931c.
V. CONCLUSION
For the foregoing reasons the judgment of the district court will be affirmed.
. Judge Gibbons attempts to distinguish the case at bar from Reeves by asserting that cement manufacturing is "a highly competitive market dominated by private enterprise.” Diss. Op. at 259. This assertion, however, is contradicted by the facts of Reeves itself. The State of South Dakota built the cement plant at issue in that case not to compete with those operated by private enterprises but because no cement plant was operating in the state. See 447 U.S. at 430-31 & n. 1, 100 S.Ct. at 2273-74 & n. 1.
. Judge Gibbons states that “the operation of a municipal landfill is no more an entry into a local market than is the operation of a municipal school system.” Diss. Op. at 259. We know of no case, however, that holds that municipalities must permit out-of-state students to matriculate in its public schools on equal terms with in-state students in order to comply with the commerce clause. Indeed, the Supreme Court has summarily affirmed a decision upholding a state statute requiring out-of-state students to pay higher tuition than in-state students in order to attend a state university, see Sturgis v. Washington, 414 U.S. 1057, 94 S.Ct. 563, 38 L.Ed.2d 464, aff’g mem. 368 F.Supp. 38 (W.D. Wash.1973) (three-judge court), and has upheld state residence requirements governing entitlement to tuition-free public schooling on the ground that a residence requirement “furthers the substantial state interest in assuring that services provided for its residents are enjoyed only by residents,” Martinez v. Bynum, 461 U.S. 321, 328, 103 S.Ct. 1838, 1842, 75 L.Ed.2d 879 (1983). See also Reeves, 447 U.S. at 442, 100 S.Ct. at 2280.
