KING, Chief Judge: Plaintiffs Harold Cox et al. filed suit against Defendant City of Dallas, Texas and Defendant Jeffrey A. Saitas, Executive Director of the Texas Natural Resource Conservation Commission, alleging violations of the Resource Conservation and Recovery Act, 42 U.S.C. § 6901 et seq. The City appeals from the district court’s judgment granting Plaintiffs injunctive relief under § 6972(a)(1)(B). Plaintiffs appeal from the district court’s judgment denying injunctive relief against Saitas. For the following reasons, we AFFIRM. I. FACTUAL AND PROCEDURAL BACKGROUND This case involves two consolidated citizen suits brought pursuant to the Resource Conservation and Recovery Act (“RCRA”), 42 U.S.C. § 6901 et seq., concerning two open garbage dumps in Dallas, Texas — an 85-acre lot located at 523 Deepwood Street (the “Deepwood dump”) and an adjacent 40-acre lot (the “South Loop 12 dump”). Zoned for residential use, the Deepwood and South Loop 12 dumps have been used for sand and gravel mining and illegal dumping for over twenty-five years. Substantial deposits of uncovered solid waste, including household waste, tires, demolition debris, insulation, asphalt shingles, abandoned automobiles, jugs and bottles labeled “sulfuric acid” and “nitric acid,” 55-gallon drums, and syringes, are on the properties. The dumps adjoin residential neighborhoods and a tributary to the Trinity River and are partially in the flood plain of the Trinity River. Neither dump has been upgraded or closed according to sanitary landfill criteria. See 42 U.S.C. § 6944(a). Residents adjacent to the dumps report the appearance of snakes and rats in their backyards since the beginning of the illegal dumping, and the dumps are easily accessible to children in the neighborhood. Since at least 1976, the State of Texas and the City of Dallas, Texas (the “City”) have been aware of open dumping on both sites. A. History of the Deepwood Dump In August 1976, officials from the Texas Natural Resource Conservation Commission (the “TNRCC”) and the City’s sanitation department visited the Deepwood dump and prepared a report that called for continuing surveillance of the site. In 1983, the City conducted soil and water tests at the Deepwood dump in response to complaints from nearby residents that illegal dumping was taking place. The City’s report and test results, which made clear that the Deepwood dump was being used for the disposal of solid waste, were sent to the State for analysis. In 1987, the City filed suit in state court against the owners of the Deepwood dump for dumping solid waste without a state permit and joined the TNRCC as a necessary party. In December 1989, the state court entered a final judgment, requiring the Deepwood dump owners to submit and implement a plan for closure of the site. An April 1991 inspection revealed that the Deepwood dump had not been cleaned up or closed, and the City filed a contempt motion. This motion was not heard by the state court, and no further action was taken by the State or the City to enforce the judgment. During this time, the City contracted with Billy Nabors and Dallas Demolition Excavating Co. (“Dallas Demolition”) to conduct demolitions of City property. These City contractors disposed of their debris at the Deepwood dump. The City’s contracts with Dallas Demolition did not specify that waste materials generated by City activities must be properly disposed of in a legal landfill. The City was aware that Dallas Demolition dumped at the Deepwood dump. However, even after the City’s attorneys had learned of Dallas Demolition’s illegal acts, the City continued to use Dallas Demolition. Also, the City designed and implemented a plan to reclaim the area from the flood plain by depositing fill material in the low spots. The plan’s objective was to collect more tax revenue from the area by eventually rezoning it for industrial purposes. In 1982, Terry Van Sickle began operating the Deepwood dump with land use and fill permits issued by the City. Van Sickle overtly stated his intention to dump solid waste at the Deepwood dump when he submitted his application to the City: “Fill old pits with solid waste ‘means all putrescible and non putrescible discarded materials or unwanted rock, dirt, metal, sand gravel wood etc. [sic].’” The City subsequently issued a certifieate-of-occu-pancy permit based on this application. While this certificate stated that the use was to be for the “mining of sand and gravel,” it did not specifically restrict the types of fill material. Furthermore, the City’s Public Works Department later granted Van Sickle “[permission to fill the mined areas.” This grant also did not restrict the types of fill material, although Van Sickle had made his intentions clear regarding the solid waste fill he wished to employ in the dump. In its own documents, the City admits that “control at the site[s] has been loose and in a few cases improper material has been used for fill ... [and] some approved flood plain areas have had large amounts of decomposable material placed in them.” At a Board of Adjustment hearing, the City considered the impact of operations at the Deepwood dump on the community. Although residents adjacent to the dump provided information about the illegal dumping and the hazards at the dump and requested that the Board put an end to the use of the dump, the Board did not act to terminate the dumping. Plaintiffs contend that it was in the City’s interest to continue the filling of the land because it would further the City’s plan of elevating the area, thus reclaiming it from the flood plain (which would then permit the City to rezone the land for industrial use, making the area more financially profitable for the City). Until the district court’s injunction, the City had never revoked the eertifieate-of-occupancy permit for the Deepwood site. Herman Nethery, the current owner of the Deepwood dump, operated an illegal open dump at the Deepwood site from 1994 through 1997. The State inspected the Deepwood dump several times from 1995 to 1997 and discovered massive illegal dumping, including asbestos, benzene, and medical waste. The State also noted in its own reports that there was an imminent threat of the discharge of municipal solid waste into Elam Creek, a tributary of the Trinity River, because of the concentrated dumping. In addition, the State observed that shingles and construction and demolition debris at the dump may cause contamination of surface and ground water through the leaching of contaminates from the debris by rainwater. For several months during 1988 and during 1997, the Deepwood dump caught fire and burned, and a significant fire hazard still exists at the site. Despite this history, in August 1994, the City granted Nethery a permit allowing mining use of the Deepwood dump. The City failed to follow its own procedures of issuing permits: no inspection was conducted prior to the issuance of the permit, and no test zone was established around the areas where illegal solid waste had been deposited. In 1995, the City filed suit against Neth-ery in state court alleging violations of the Texas Solid Waste Disposal Act (the “TSWDA”), and the State intervened. The state court entered judgment against Nethery for $15,000,060. The judgment does not require that any of the imposed civil penalties be used for cleaning up the dump. In addition to the state civil actions, the State criminally prosecuted Nethery and Herman Lee Gibbons, an operator at the Deepwood dump. Both were convicted of violating Texas organized crime laws relating to the financing of the illegal dump, and both were incarcerated in Texas on those charges. The City informed the State and the United States Environmental Protection Agency (“EPA”) that the Deepwood dump poses long-term fire and health hazards for the neighborhood and requested funds to remediate the dump. The State and the EPA refused to provide funds to clean up the dump. B. History of the South Loop 12 Dump In 1964, the City entered into an agreement to use the South Loop 12 site as a sanitary landfill. In 1972, the then-owner of the site excluded the City from dumping because the City had not complied with the conditions in the agreement (i.e., to cover the refuse that it had dumped with at least eighteen inches of compact soil). In addition, the City never canceled this agreement. In 1989, the City and the State sued the owners of the South Loop 12 dump in state court for violating the TSWDA. The state court entered an Agreed Final Judgment in 1990, ordering the owners to clean up the dump. An April 1991 inspection found that no corrective action had been taken, but the City and State did nothing to gain compliance with the 1990 judgment. As was the case with the Deepwood dump, there currently exists a substantial danger of fires from the solid waste present on the site, and the dump is also easily accessible to children. The South Loop 12 site remains an open dump, and the State has not cleaned, and does not intend to clean up, the site. C. Procedural History of Current Litigation In February 1997, Plaintiffs, homeowners in residential areas adjoining these dumps, brought a citizens suit in federal court against the owners of the Deepwood dump, the City, and Saitas for injunctive relief under the RCRA, 42 U.S.C. § 6972(a)(1). This suit was consolidated with Plaintiffs’ July 1998 citizens suit against the City and Saitas regarding the South Loop 12 dump. Plaintiffs alleged, inter alia, that the City violated 42 U.S.C. § 6972(a)(1)(B) by “contributing to” illegal open dumping at both sites, that Saitas failed to classify the dumps on the EPA’s Open Dump Inventory (“ODI”), and that Saitas failed to comply with the corresponding RCRA obligation of cleaning up the dumps. On October 5, 1998, the district court certified an injunctive relief class of homeowners near or adjacent to the Deepwood dump. As to the South Loop 12 dump, Plaintiffs are all individually named. On December 17, 1998, the district court bifurcated the injunctive relief and damages portions of the suits. The court then held a bench trial regarding the injunctive relief claims on July 14, 1999. The Final Judgment, entered on August 27, 1999, granted Plaintiffs injunctive relief against the City on both dumps, finding that the City had “contributed to” illegal open dumping, but denied injunctive relief against Saitas. The district court’s injunction required the City, inter alia, to (1) erect a fence around both sites, (2) monitor the sites for methane gas and fire hazards, (3) prevent future open dumping, (4) remove all solid waste from the sites without harming adjoining properties, and (5) restore the sites to non-hazardous conditions. See Meghrig v. KFC Western, Inc., 516 U.S. 479, 484, 116 S.Ct. 1251, 134 L.Ed.2d 121 (1996) (stating that “a private citizen suing under § 6972(a)(1)(B) could seek a mandatory injunction, i.e., one that orders a responsible party to ‘take action’ by attending to the cleanup and proper disposal of toxic waste, or a prohibitory injunction, i.e., one that ‘restrains’ a responsible party from further violating [the] RCRA”). The City timely appealed, claiming that the district court erred in holding that the City “contributed to” dumping at the sites. Plaintiffs also timely appealed, arguing that the district court erred in holding that Saitas could not be held liable for violating the RCRA. II. STANDARD OF REVIEW “We review the district court’s findings of fact for clear error and legal issues de novo. However, we may affirm for reasons other than those relied upon by the district court.” Joslyn Mfg. Co. v. Koppers Co., Inc., 40 F.3d 750, 753 (5th Cir.1994) (citations omitted). A district court’s ruling is not clearly erroneous unless we are left with the definite and firm conviction that a mistake has been made. See United States v. Bentley-Smith, 2 F.3d 1368, 1377 (5th Cir.1993). In addition, “[w]e review the district court’s grant of a permanent injunction for abuse of discretion.” Hopwood v. Texas, 236 F.3d 256, 276 (5th Cir.2000). III. THE CITY’S APPEAL In the district court, Plaintiffs asserted the following four claims against the City: (1) “contributing to” liability under 42 U.S.C. § 6972(a)(1)(B) at the Deepwood dump, (2) “contributing to” liability under § 6972(a)(1)(B) at the South Loop 12 dump, (3) liability under § 6945(a) at the Deepwood dump, and (4) liability under § 6945(a) at the South Loop 12 dump. The district court found the City liable under § 6972(a)(1)(B) for both the Deep-wood and South Loop 12 dumps, but found that Plaintiffs had not met their burden as to their § 6945(a) claims. Plaintiffs are not appealing the district court’s decision on the § 6945(a) claims, but the City is appealing the liability findings under § 6972(a)(1)(B). In order to supply a better understanding of the RCRA, we provide at the outset a brief description of nuisance at common law. We then lay out the statutory framework of “contributing to” liability under § 6972(a)(1)(B). Finally, we assess whether the district court’s ruling that the City fell within the statutory reach of § 6972(a)(1)(B) was in error. A Nuisance at Common Law Nuisance principles form the core doctrinal foundation for modern environmental statutes, including the RCRA. The nuisance action originated in the twelfth century. See Restatement (SeCond) of Torts § 821D cmt. a (1979). Courts first recognized “private” nuisances, see id., and by the sixteenth century, began to recognize “public” nuisances, see id. § 821C cmt. a. “A private nuisance is a nontrespassory invasion of another’s interest in the private use and enjoyment of land.” Id. § 821D. A public nuisance, on the other hand, involves an unreasonable interference with a right common to the general public. See id. § 821B. In determining whether conduct amounts to a public nuisance, courts consider, inter alia, whether the conduct involves a significant interference with public health, safety, peace, comfort, or convenience. See id. Private and public nuisances are not set apart in rigid, mutually exclusive categories. On the contrary, “[w]hen the nuisance, in addition to interfering with the public right, also interferes with the use and enjoyment of the plaintiffs land, it is a private nuisance as well as a public one.” Id. § 821C cmt. e. See also, e.g., Ozark Poultry Prods., Inc. v. Garman, 251 Ark. 389, 472 S.W.2d 714, 715 (1971) (stating that landowners’ suit against a factory that polluted air and water could be both a public and private nuisance). These interests (i.e., in a public right and in the use and enjoyment of one’s land) “may be invaded by any one of the types of conduct that serve in general as bases for all tort liability.” Restatement (Second) of Torts § 822 cmt. a. The Restatement explains that one is subject to liability for a private nuisance (1) if one’s conduct is the legal cause of an invasion of another’s interest and (2) if the invasion is either (a) “intentional and unreasonable” or (b) “unintentional and otherwise actionable under the rules controlling liability for negligent or reckless conduct, or for abnormally dangerous conditions or activities.” Id. § 822. The rules of strict liability, i.e., liability imposed without regard to the defendant’s negligence or intent to harm, are frequently applied to abnormally dangerous activities, see Restatement (Second) of Torts § 519 (1977), although they are imposed in other nuisance situations as well. The private nuisance liability framework of Restatement § 822 is also generally applicable in public nuisance situations. See Restatement (Second) of Torts § 822 cmt. a. However, public nuisance law tends to impose liability more often on the basis of strict liability. See, e.g., New York v. Shore Realty Corp., 759 F.2d 1032, 1051 (2d Cir.1985) (applying New York law and stating that liability for public nuisance exists “irrespective of negligence or fault”); Concerned Citizens of Bridesburg v. City of Phila., 643 F.Supp. 713, 726 (E.D.Pa.1986) (“At common law, neither individuals nor municipalities have the right to maintain for any period of time activities that constitute a public nuisance, irrespective of lack of fault or due care.”); Wood v. Picillo, 443 A.2d 1244, 1248 (R.I.1982) (stating, in a case in which multiple private plaintiffs sued under public and private nuisance alleging that the defendants’ chemical dump site was polluting the soil, that “generally this court has not required plaintiffs to establish negligence in nuisance actions”); id. at 1247 (stating that “liability in nuisance is predicated upon unreasonable injury, rather than upon unreasonable conduct”); Branch v. W. Petroleum, Inc., 657 P.2d 267, 274 (Utah 1982) (“Unlike most torts, [nuisance law] is not concerned with the nature of the conduct causing the damage, but with the nature and relative importance of the interests interfered with or invaded.”). Two basic remedies are available in nuisance actions — damages and injunctions. See Restatement (Second) of Torts § 821B cmt. i; id. § 821C (stating that to maintain a damage action for a public nuisance, the plaintiff must have suffered damage different in kind from that suffered by the general public and that to maintain an injunctive action for a public nuisance, the plaintiff must have a right to recover damages or the authority to represent a political subdivision in the matter or standing to sue in a citizen’s action); id. § 821F (revealing that a private or public nuisance action for damages may be maintained only by those who have suffered “significant harm”); id. § 822 cmt. d (providing that an “injunction may be obtained in a proper case against a threatened private nuisance, but an action cannot be maintained at law unless harm has already been suffered” and referencing § 821C for a similar distinction in the realm of public nuisances); see also Developments in the Law—Injunctions, 78 Harv. L.Rev. 994, 1001 (1965) (explaining that injunctions are usually granted when damages are inadequate, such as with ongoing nuisances in which numerous suits or future damage awards would be required). The theory of nuisance lends itself naturally to combating the harms created by environmental problems. See Geo-Tech Reclamation Indus., Inc. v. Hamrick, 886 F.2d 662, 665 (4th Cir.1989) (stating that “the operation of a landfill ... was recognized as a nuisance even by the early common law”). One commentator succinctly described environmental jurisprudence, stating: “The deepest doctrinal roots of modern environmental law are found in principles of nuisance.... Nuisance actions have involved pollution of all physical media — air, water, land — by a wide variety of means.... Nuisance actions have challenged virtually every major industrial and municipal activity which is today the subject of comprehensive environmental regulation.... Nuisance theory and case law is the common law backbone of modern environmental and energy law.” William H. Rodgers, Jr., Handbook on Environmental Law § 2.1, at 100 (1977). Specifically, as regards the RCRA, Congress indicated that the statute embodied common law concepts of nuisance. See S.Rep. No. 96-172, at 5 (1979), reprinted in 1980 U.S.C.C.A.N. 5019, 5023 (“[The RCRA] is essentially a codification of common law public nuisance remedies .... [and], therefore, incorporates the legal theories used for centuries to assess liability for creating a public nuisance (including [the theories of] intentional tort, negligen-cy, and strict liability) and to determine appropriate remedies.... However, .... [s]ome terms and concepts ... are meant to be more liberal than their common law counterparts.”); cf. Solid Waste Agency v. U.S. Army Corps of Eng’rs., 101 F.3d 503, 505 (7th Cir.1996) (noting that the interests protected by the Clean Water Act “overlap to a great extent the interests that nuisance law protects”). See generally infra Part III.B.2. Having provided a brief summary of the common law negligence principles that underlie the RCRA, we next proceed to lay out the regulatory framework of the RCRA as it applies to the facts of this case. B. Section 6972(a)(1)(B) Section 6972(a)(1)(B) of the RCRA provides in relevant part: [A]ny person may commence a civil action on his own behalf — against any person, including the United States and any other governmental instrumentality or agency, to the extent permitted by the eleventh amendment to the Constitution, and including any past or present generator, past or present transporter, or past or present owner or operator of a treatment, storage, or disposal facility, who has contributed or who is contributing to the past or present handling, storage, treatment, transportation, or disposal of any solid or hazardous waste which may present an imminent and substantial endangerment to health or the environment. 42 U.S.C. § 6972(a)(1)(B) (emphasis added). Parsing the language of § 6972(a)(1)(B), we find it contains essentially three elements. To prevail on a “contributing to” claim, a plaintiff is required under § 6972(a)(1)(B) to demonstrate: (1) that the defendant is a person, including, but not limited to, one who was or is a generator or transporter of sohd or hazardous waste or one who was or is an owner or operator of a sohd or hazardous waste treatment, storage, or disposal facility; (2) that the defendant has contributed to or is contributing to the handling, storage, treatment, transportation, or disposal of sohd or hazardous waste; and (3) that the sohd or hazardous waste may present an imminent and substantial endangerment to health or the environment. See, e.g., United States v. Aceto Agric. Chems. Corp., 872 F.2d 1373, 1382 n. 9 (8th Cir.1989); Zands v. Nelson (“Zands II ”), 797 F.Supp. 805, 809 (S.D.Cal.1992). We turn now to the district court’s finding that the City falls within the statutory reach of § 6972(a)(1)(B) for both the Deep-wood and South Loop 12 dumps. 1. Any Person First, the RCRA states that “any person” may be held liable, “including” past or present generators, transporters, owners, or operators. See 42 U.S.C. § 6972(a)(1)(B); H.R.Rep. No. 98-198, Part I, at 48 (1983), reprinted in 1984 U.S.C.C.A.N. 5576, 5607 (stating that “anyone who has contributed or is contributing to the creation, existence, or maintenance of an imminent and substantial endangerment is subject to [the RCRA]” and that “such persons include, but are not limited to, past and present generators ..., past and present owners and operators ..., and past and present transporters” (emphasis added)); Zands II, 797 F.Supp. at 809 (stating that “the word ‘including’ does not limit the definition of the word ‘person’ ”); cf. Cobell v. Norton, 240 F.3d 1081, 1100 (D.C.Cir.2001) (“It is hornbook law that the use of the word including indicates that the specified list ... that follows is illustrative, not exclusive.”) (alteration in original) (internal quotations omitted) (quoting in parenthetical Puerto Rico Maritime Shipping Auth. v. ICC, 645 F.2d 1102, 1112 n. 26 (D.C.Cir.1981)); United States v. Grassie, 237 F.3d 1199, 1215 (10th Cir.2001) (regarding “the statutory use of the word ‘including’ ... as the preface for a representative or illustra-five example, and not as a term of restriction or exclusion for anything not expressly specified”); United States v. Canada, 110 F.3d 260, 263 (5th Cir.1997) (stating that the term “includes” indicates a non-exhaustive list). In addition, it is undisputed that the City has been and is a generator of solid waste. Municipal activities, such as basic office operations in city buildings, demolition, and construction, generate waste. See Meghrig, 516 U.S. at 483, 116 S.Ct. 1251 (stating that the “RCRA is a comprehensive environmental statute”); C&A Carbone, Inc. v. Town of Clarkstown, 511 U.S. 383, 408, 114 S.Ct. 1677, 128 L.Ed.2d 399 (1994) (O’Connor, J., concurring in judgment) (stating that the “RCRA is a sweeping statute intended to regulate solid waste from cradle to grave”); 1 James T. O’Reilly et al., RCRA and Superfund: A PRACTICE Guide with Forms § 2.08, at 2-25 (2d ed. 2000) (“The ‘cradle to grave’ intent of the RCRA law is illustrated by the law’s inclusion of generators, transporters, and disposers within the broad reach of the statute.”); see also Zands v. Nelson, 779 F.Supp. 1254, 1264 (S.D.Cal.1991) (“Zands I”) (stating that the term “generators” indicates that the “RCRA applies to individuals who do no more than create solid waste”). Specifically, on this record, the City generated solid waste through its demolition activities. 2. Has Contributed to or Is Contributing to Second, the district court did not err as a matter of law in interpreting the “contributing to” prong of § 6972(a)(1)(B). In addition, its finding that the City satisfied the requirements of the provision was not clear error. In so concluding, we first lay out the basic framework that will guide our analysis and then examine the evidence relating to each dump. a. Construction of the Term, “Contribute” The RCRA does not define the term “contribute” or any variation thereof. “This silence compels us to ‘start with the assumption that the legislative purpose is expressed by the ordinary meaning of the words used.’ ” Russello v. United States, 464 U.S. 16, 21, 104 S.Ct. 296, 78 L.Ed.2d 17 (1983) (quoting Richards v. United States, 369 U.S. 1, 9, 82 S.Ct. 585, 7 L.Ed.2d 492 (1962)); see also Green Tree Fin. Corp. v. Randolph, 531 U.S. 79, 121 S.Ct. 513, 519, 148 L.Ed.2d 373 (2000) (stating that “[b]ecause the [statute] does not define [a term] or otherwise suggest that the ordinary meaning of [the term] should not apply, [the Supreme Court accords] the term its well-established meaning”); Asgrow Seed Co. v. Winterboer, 513 U.S. 179, 187, 115 S.Ct. 788, 130 L.Ed.2d 682 (1995); cf. Hallstrom v. Tillamook County, 493 U.S. 20, 31, 110 S.Ct. 304, 107 L.Ed.2d 237 (1989) (adopting plain language meaning for the RCRA notice requirement in § 6972(b)). Webster’s Dictionary defines “contribute” as to “have a share in any act or effect.” WebsteR’s ThiRD New International Dictionary 496 (unabridged) (1963); see also Oxford English Dictionary 849 (2d ed.1989) (“to have a part or share in producing [an effect]”); The Amerioan Heritage Dictionary of the English Language 410 (3d ed.1992) (“to help bring about a result”). Our sister circuits have drawn upon the plain meaning of the word “contribute” and on the legislative history as well to interpret the “contributing to” phrase under the analogous § 6973 provision. See, e.g., Aceto, 872 F.2d at 1383 (“The relevant legislative history supports a broad, rather than a narrow, construction of the phrase ‘contributed to.’ ”); United States v. Waste Indus., Inc., 734 F.2d 159, 167 (4th Cir.1984) (“Congress’s intent, then, was to establish a standard of liability by incorporating and expanding upon the common law.”). The Court of Appeals for the Fourth Circuit aptly summarized congressional intent regarding interpretations of phrases such as “contributing to”: [Congress has mandated] that the former common law of nuisance, as applied to situations in which a risk of harm from solid or hazardous wastes exists, shall include new terms and concepts which shall be developed in a liberal, not a restrictive, manner. This ensures that problems that Congress could not have anticipated when passing the [RCRA] will be dealt with in a way minimizing the risk of harm to the environment and the public. Waste Indus., 734 F.2d at 167. (citations omitted). Therefore, we follow our sister circuits’ lead and interpret “contribute” to mean “have a part or share in producing an effect.” b. The Required Level of Fault As to the fault standard under which such “contributions” are held actionable, we note that the one circuit that has addressed this specific issue has held that the RCRA imposes strict liability, i.e., liability imposed without regard to the defendant’s negligence or intent to harm. Cf. United States v. Northeastern Pharm. & Chem. Co., 810 F.2d 726, 741 (8th Cir.1986) (stating, in a case arising under § 6973 (see supra note 22), that Congress intended to impose liability “without fault or negligence” and specifically on past non-negligent off-site generators and transporters); Aceto, 872 F.2d at 1377 (citing Northeastern and stating that § 6973 “has been interpreted to impose strict liability”). Some other courts have also come to the same conclusion. See, e.g., Zands II, 797 F.Supp. at 809-10. We have no reason to consider here whether strict liability may be a basis for liability under the RCRA. The district court did not hold the City strictly liable for the waste that it generated and that was deposited in the Deepwood and South Loop 12 dumps. In the case of the South Loop 12 dump, the City did not dispute that it used the site as a municipal dump. In the case of the Deepwood dump, the district court found, and we agree, that there is a compelling ease on the record that the City’s actions were negligent, i.e., that the City failed to exercise due care in selecting or instructing the entity actually conducting the disposal of the City’s waste. c. The Evidence Regarding the Deepwood and South Loop 12 Dumps We now examine the evidence regarding each dump and conclude that the district court did not commit clear error in finding that the evidence established § 6972(a)(1)(B) “contributing to” liability for the City. i. Deepwood Dump The RCRA creates, at the very least, a duty on the part of generators not to dispose of their waste in such a manner that it may present an imminent and substantial endangerment to health or the environment. Negligent oversight of disposal is actionable under the RCRA. See supra note 27 and accompanying text. As described supra in Part I.A, the City contracted with Billy Nabors and Dallas Demolition to conduct demolitions of City property. These City contractors dumped loads of debris at the Deepwood dump. The City’s contracts with Dallas Demolition did not specify that waste materials generated by the City’s activities must be properly disposed of in a legal landfill. The City was aware that Dallas Demolition engaged in illegal dumping and operated its own unauthorized waste site. Furthermore, the City’s attorneys were informed that Dallas Demolition dumped at the Deepwood dump. However, even after the City’s attorneys had learned that Dallas Demolition had been dumping illegally in Dallas, the City continued to work with Dallas Demolition. The district court did not clearly err in finding that this “lax oversight” of its contractors and their disposal of City waste is evidence of the City’s “contributing to” liability. Cf. Blue Legs v. U.S. Bureau of Indian Affairs, 867 F.2d 1094, 1099 (8th Cir.1989) (finding that federal government agencies “contributed to” open dumping by “generating solid waste, contracting for its disposal and, in some instances, transporting solid waste to dumps operated in violation of federal law” (emphasis added)). The City argues that there is no evidence in the record that the City’s waste actually went into the Deepwood dump. The City asserts, instead, that the contracts simply demonstrate that it could have used Billy Nabors or Dallas Demolition to haul trash, but that there is no evidence that it actually did do so (and, even if it did utilize these haulers, that the City’s particular waste was taken to the Deepwood dump). We find little merit in this argument. First, the district court reasonably inferred that the City’s waste went into the Deepwood dump, and on this record, this inference is not clear error. The City Council allocated funds for the demolition actions, and the City Council, subsequent to a bidding process, awarded specific contracts to Dallas Demolition and Billy Na-bors, even after City attorneys knew that they were dumping illegally at the Deep-wood dump. Given that the City specifically hired these contractors to perform certain jobs, a logical conclusion is that the City used them for those jobs. A mere assertion from the City that the jobs might not have been performed is insufficient to alter this conclusion. The City’s actions therefore snugly fit the “failed to exercise due care in selecting or instructing the entity actually conducting the disposal” statement from S.Rep. No. 96-172, at 5 (1979), reprinted in 1980 U.S.C.C.A.N. 5019, 5023. See supra Part III.B.2.b. This situation also closely parallels an example considered in a 1979 House Committee Report and a 1979 Senate Report, i.e., that a generator of solid waste is subject to liability even when someone else conducted the disposal at the generator’s request. See S.Rep. No. 96-172, at 5 (1979), reprinted in 1980 U.S.C.C.A.N. 5019, 5023; H.R. Comm. PRINT No. 96-IFC 31, at 31 (1979). Therefore, the district court did not err in assessing § 6972(a)(1)(B) liability against the City based on the City’s negligent actions regarding the disposal of its waste. ii. South Loop 12 Dump The City does not dispute that it used the South Loop 12 site as a municipal landfill from 1964 until at least 1972. An owner of South Loop 12 fenced the site and hired a guard to stop the City from dumping because the City would not properly cover the refuse it had dumped there. The City’s primary argument is that because its use ended in 1972 and because the RCRA was not enacted until 1976, it cannot be held liable under § 6972(a)(1)(B). We do not agree. Section 6972(a)(1)(B) is clear that it applies to both past and present acts, as the adjectives “past and present” are specifically included. We have also previously confirmed that “[w]e understand [the] language [of § 6972(a)(1)(B) ] to provide a claim for injunctive relief based on either past or present conduct.” Tanglewood E. Homeowners v. Charles-Thomas, Inc., 849 F.2d 1568, 1576 (5th Cir.1988) (emphasis added) (the activities at issue in the case had also occurred before 1976); Northeastern, 810 F.2d at 739 (stating that the analogous provision of § 6973, see supra note 22, “specifically applies to past generators and transporters” and rejecting the defendant’s argument that pre-1976 dumping should not be a basis for RCRA liability); see also infra Part III.B.3 (explaining that although the endangerment must currently exist, the actions causing the endangerment may have occurred wholly in the past); cf. Gwaltney of Smithfield, Ltd. v. Chesapeake Bay Found., Inc., 484 U.S. 49, 57 & n. 2, 108 S.Ct. 376, 98 L.Ed.2d 306 (1987) (noting that Congress intentionally used “language that explicitly targets wholly past violations” when it created § 6972(a)(1)(B)). “In short, the disposal of wastes [as wholly past acts] can constitute a continuing violation as long as no proper disposal procedures are put into effect or as long as the waste has not been cleaned up and the environmental effects remain remediable.” Gache v. Town of Harrison, 813 F.Supp. 1037, 1041, 1042 (S.D.N.Y.1993) (rejecting the defendant city’s argument that it had not dumped any materials in years and thus should not be held liable); United States v. Price, 523 F.Supp. 1055, 1071 (D.N.J.1981) (rejecting defendants’ argument that the RCRA could not be applied to its activities, which ceased in 1972), aff'd, 688 F.2d 204 (3d Cir.1982). The continued presence of this municipal waste in the South Loop 12 dump (so long as it presents an imminent and substantial endangerment to health or the environment, see infra Part III.B.3) is actionable under § 6972(a)(1)(B). 3. Imminent and Substantial Endangerment to Health or Environment Lastly, the district court did not err in concluding that an imminent and substantial endangerment to health or the environment existed at both dumps. At the outset, we note that the operative word in § 6972(a)(1)(B) is “may.” Thus, Plaintiffs must demonstrate that the waste “may present” such a danger. See Dague v. City of Burlington, 935 F.2d 1343, 1355 (2d Cir.1991) (“Significantly, congress used the word ‘may’ to preface the standard of liability!)]”), rev’d in part on other grounds, 502 U.S. 1071, 112 S.Ct. 964, 117 L.Ed.2d 130 (1992); Kara Holding Corp. v. Getty Petroleum Mktg., Inc., 67 F.Supp.2d 302, 310 (S.D.N.Y.1999) (emphasizing “may” in § 6972(a)(1)(B)); cf. Greenpeace, Inc. v. Waste Techs. Indus., 9 F.3d 1174, 1181 (6th Cir.1993) (contrasting the “difficult standards of § 6976(b)” with the “far less restrictive rules governing [imminent and substantial endangerment under] § 6972(a)(1)(B)”). The Supreme Court has also pointed out that the phrase “may present” communicates another idea: It “quite clearly excludes waste that no longer presents” the harm contemplated by § 6972(a)(1)(B). See Meghrig, 516 U.S. at 486, 116 S.Ct. 1251. “[T]his language ‘implies that there must be a threat which is present now, although the impact of the threat may not be felt until later.’ ” Id. (quoting Price v. U.S. Navy, 39 F.3d 1011, 1019 (9th Cir.1994)). As such, “under an imminent hazard citizen suit, the endangerment must be ongoing, but the conduct that created the endangerment need not be.” Conn. Coastal Fishermen’s Ass’n v. Remington Arms Co., Inc., 989 F.2d 1305, 1316 (2d Cir.1993); see also U.S. Navy, 39 F.3d at 1019 (stating that the language of the provision does not require actual harm, but threatened or potential harm); United States v. Waste Indus., Inc., 734 F.2d 159, 165 (4th Cir.1984) (stating that the RCRA was intended to apply to “active human conduct” and is “a means to respond to disasters precipitated by earlier poor planning” (emphasis added)). Because the RCRA does not define “imminent,” the Supreme Court, as is its customary practice, see supra Part III.B.2.a (discussing meaning of “contribute”), looked to the plain meaning of the term: “An endangerment can only be ‘imminent’ if it ‘threaten[s] to occur immediately.’” Meghrig, 516 U.S. at 485, 116 S.Ct. 1251 (alteration in original) (quoting WebsteR’s New International Dictionary of English Language 1245 (2d ed.1934)); see also Dague, 935 F.2d at 1356 (“A finding of ‘imminency’ does not require a showing that actual harm will occur immediately so long as the risk of threatened harm is pres-ent[.]”); United States v. Price, 688 F.2d 204, 213-14 (3d Cir.1982); Kara Holding, 67 F.Supp.2d at 310 (citing Meghrig); cf. Envtl. Def. Fund v. EPA, 465 F.2d 528, 535 (D.C.Cir.1972) (“An ‘imminent hazard’ may be declared at any point in a chain of events which may ultimately result in harm to the public.” (internal quotations and citation omitted)). The legislative history supports interpreting “imminent” in accordance with this plain meaning: Imminence ... applies to the nature of the threat rather than identification of the time when the endangerment initially arose. The section, therefore, may be used for events which took place at some time in the past but which continue to present a threat to the public health or the environment. H.R. Comm. PRINT No. 96-IFC 31, at 32 (1979). And finally, an endangerment is “substantial” if it is “serious.” See U.S. Navy, 39 F.3d at 1019. With this framework in place, we now examine the evidence regarding the imminent and substantial endangerment to health and the environment at each dump. a. Deepwood Dump The district court did not clearly err in concluding that the’Deepwood dump “may present an imminent and substantial endangerment to health or the environment.” See supra Part I.A. The evidence includes the following: The Deep-wood dump is adjacent to residences and is partially in the flood plain of the Trinity River; the dump is easily accessible to children; the Deepwood dump twice caught fire and burned, with the resulting fumes polluting the neighborhood air; a significant fire hazard continues to exist at the dump; the State’s reports reveal that there is an imminent threat of the discharge of municipal solid waste into Elam Creek, a tributary of the Trinity River, because of the massive illegal dumping; the State itself has noted that waste at the Deepwood dump may cause contamination of surface water and ground water through the leaching of contaminates from the debris by rainwater; asbestos, benzo(a)ath-racene, and benzene (in excess of state limits) have been detected at the Deep-wood dump; and the City itself has long maintained that the Deepwood dump poses a hazard to the public health. b. South Loop 12 Dump On appeal, the City argues that the material it dumped at the South Loop 12 dump presents no danger to health or the environment; yet, the City points to nothing in the record to support this assertion. The district court concluded that Plaintiffs have adequately demonstrated that the City’s contributions played a role in the creation of the dangers at the South Loop 12 dump, and, as will be explained below, the record well supports this conclusion. The district court did not clearly err in finding that the South Loop 12 dump satisfies the endangerment standard of § 6972(a)(1)(B). First, as the district court noted, the City itself had previously admitted that the South Loop 12 dump was a “hazard to the public health in its present condition.” Furthermore, the City’s state court judgment against the owners stated that the judgment was “necessary for the maintenance of the public health and environment.” In addition, the State’s documents themselves describe the very danger of old landfills, like the South Loop 12 dump, that were established before any of the proper closure requirements were in place: As the old waste decomposes, the cover soil can settle, ground and surface water can become contaminated with leachate, and dangerous gases can form and migrate underground. This meets the “may present an imminent and substantial endangerment” standard. Moreover, as the City failed to adhere even to the less stringent requirements in effect during the time it was dumping at the South Loop 12 dump, the dangers described in the State’s plan are even more likely to materialize. Therefore, the district court’s finding that the City was liable under § 6972(a)(1)(B) for the Deepwood and South Loop 12 dumps was not clearly erroneous. IV. PLAINTIFFS’APPEAL The district court dismissed Saitas from the case, finding that Plaintiffs had not met their burden as to any of their claims against Saitas. On appeal, Plaintiffs contend that they did meet their burden as to their claims that Saitas violated specific regulations, requirements, and standards that took effect pursuant to the solid waste disposal provisions of the RCRA. They argue that these provisions require Saitas to inventory all landfills in the state, to classify those that do not meet EPA standards for sanitary landfills as open dumps, to achieve either the closing of the dumps (such that they are in compliance with EPA standards) or the upgrading of the dumps to sanitary landfill status, to eliminate the health hazards of the dumps, and to take steps to prevent future health hazards. See 42 U.S.C. §§ 6943(a)(2) & (3), 6944, 6945, 6947; 40 C.F.R. § 256.23(a), (c), (d). Plaintiffs seek to enforce these obligations via the citizen suit provision in 42 U.S.C. § 6972(a)(1)(A). Before we address Saitas’s arguments with respect to the threshold issues of standing and Eleventh Amendment immunity, and in order to provide context for these arguments, we pause here to lay out the relevant statutory and regulatory background. We then continue with our analysis. A. Statutory and Regulatory Framework Under the RCRA, states are able to receive federal financial and other assistance if they comply with various RCRA provisions and the corresponding EPA regulations. One such requirement is that states must submit solid waste management plans that “prohibit the establishment of new open dumps within the State,” and ensure that solid waste will be “utilized for resources recovery or ... disposed of in sanitary landfills ... or otherwise disposed of in an environmentally sound manner.” 42 U.S.C. § 6943(a)(2). Further, the plan must “provide for the closing or upgrading of all existing open dumps within the State pursuant to the requirements of section 6945.” Id. § 6943(a)(3). Aong these lines, a state is to provide the EPA with a list of open dumps in the state, which the EPA must publish in the ODI. See 42 U.S.C. § 6945(b); 40 C.F.R. pt. 256. The ODI was meant “[t]o assist the States in complying with section 6943(a)(3).” 42 U.S.C. § 6945(b). Section 6945(a) in turn specifies that the state plan must “contain a requirement that all existing disposal facilities or sites for solid waste in [the] State which are open dumps listed in the [ODI] ... shall comply with such measures as may be promulgated by the Administrator to eliminate health hazards and minimize potential health hazards.” Id. § 6945(a). These regulations, promulgated by the EPA, provided “guidelines for the development and implementation of State solid waste management plans.” Guidelines for Development and Implementation of State Solid Waste Management Plans, 44 Fed. Reg. 45066, 45066 (July 31, 1979). States were required to classify existing solid waste disposal facilities, with the open dumps to be published in the ODI. See 40 C.F.R. § 256.23(a). “[A]ny facility which fails to comply with any one element of the ‘Criteria for Classification of Solid Waste Disposal Facilities and Practices’ ... is an open dump.” Solid Waste Disposal; Inventory of Open Dumps, 50 FecLReg. 41952, 41952 (Oct. 16, 1985) (explaining that facilities that did not satisfy the sanitary landfill criteria and which were not facilities for the disposal of hazardous waste were to be classified as open dumps). “For each facility classified as an open dump the State shall take steps to close or upgrade the facility.” 40 C.F.R. § 256.23(c). In addition, while “providing for the closure of open dumps the State shall take steps necessary to eliminate health hazards and minimize potential health hazards.” Id. § 256.23(d). In accordance with these statutory and regulatory requirements, the State of Texas submitted its Solid Waste Management Plan (“the state plan”), which was subsequently approved by the EPA. See Approval of Texas Solid Waste Management Plan, 48 Fed.Reg. 3986, 3986 (Jan. 28, 1983). The district court found that the State “adopted a strategy of only listing on the ODI those sites that had previously received a permit” from the State. The district court further found that because most dumps do not apply for a state permit, “this strategy greatly reduced the number of existing open dumps in Texas that could potentially find their way onto the ODI.” The court went on to state in its Findings of Fact and Conclusions of Law that the State “never informed the EPA of its intent to unilaterally narrow the scope of the ODI.” B. Standing and Eleventh Amendment Immunity On appeal, Saitas puts forth various jurisdictional issues and argues that, even if the merits were to be reached, he did not violate the RCRA. We examine each of the threshold issues in turn. Not finding them to be viable in the instant case, we then examine the merits of Plaintiffs’ claims, concluding that the district court did not err in finding in favor of Saitas. Saitas asserts that Plaintiffs lack standing and also that he is immune from suit under the Eleventh Amendment. Standing is a jurisdictional doctrine that the Supreme Court has held must be decided before the merits of a case. See Steel Co. v. Citizens for a Better Env’t, 523 U.S. 83, 93-102, 118 S.Ct. 1003, 140 L.Ed.2d 210 (1998) (rejecting the doctrine of “hypothetical jurisdiction”); see also Schlesinger v. Reservists Comm. to Stop the War, 418 U.S. 208, 215, 94 S.Ct. 2925, 41 L.Ed.2d 706 (1974) (stating that “the concept of justiciability, which expresses the jurisdictional limitations imposed upon federal courts by the ‘case or controversy’ requirement of Art. Ill, embodies ... [among other doctrines] the standing doctrine! ]”)• “While the Eleventh Amendment is jurisdictional in the sense that it is a limitation on the federal court’s judicial power, ... [the Supreme Court has] recognized that it is not coextensive with the limitations on judicial power in Article III.” Calderon v. Ashmus, 523 U.S. 740, 745 n. 2, 118 S.Ct. 1694, 140 L.Ed.2d 970 (1998); Laje v. R.E. Thomason Gen. Hosp., 665 F.2d 724, 726 n. 2 (5th Cir.1982) (stating that Eleventh Amendment claims “are jurisdictional in nature” (emphasis added)). The Supreme Court has also stated that standing must be examined before the Eleventh Amendment. See Calderon, 523 U.S. at 745, 118 S.Ct. 1694 (stating that the Court “must first address whether [the action] is the sort of ‘Article IIP ‘case or controversy’ to which federal courts are limited”). 1. Standing Article III, § 2 of the Constitution “extends the ‘judicial Power’ of the United States only to ‘Cases’ and ‘Controversies.’ ” Steel Co., 523 U.S. at 102, 118 S.Ct. 1003. “That a suit may be a class action ... adds nothing to the question of standing, for even named plaintiffs who represent a class must allege and show that they personally have been injured, not that injury has been suffered by other, unidentified members of the class to which they belong and which they purport to represent.” Lewis v. Casey, 518 U.S. 343, 357, 116 S.Ct. 2174, 135 L.Ed.2d 606 (1996) (alteration in original) (internal quotations omitted) (quoting Simon v. Eastern Ky. Welfare Rights Org., 426 U.S. 26, 40, n. 20, 96 S.Ct. 1917, 48 L.Ed.2d 450 (1976)). A plaintiff must demonstrate that he or she satisfies the three constitutional requirements of standing: (1) injury in fact, (2) causation, and (3) redressability. See Bennett v. Spear, 520 U.S. 154, 167, 117 S.Ct. 1154, 137 L.Ed.2d 281 (1997); Lujan v. Defenders of Wildlife, 504 U.S. 555, 560-61, 112 S.Ct. 2130, 119 L.Ed.2d 351 (1992). A plaintiff suffers injury in fact when there has been “an invasion of a legally protected interest which is (a) concrete and particularized, and (b) actual or imminent, not conjectural or hypothetical.” Lujan, 504 U.S. at 560, 112 S.Ct. 2130 (internal quotations and citations omitted). The causation requirement is met when the injury is such that it is “ ‘fairly ... trace[able] to the challenged action of the defendant, and not ... th[e] result [of] the independent action of some third party not before the court.’ ” Id. at 560-61, 112 S.Ct. 2130 (alterations in original) (quoting Simon v. Eastern Ky. Welfare Rights Org., 426 U.S. 26, 41-42, 96 S.Ct. 1917, 48 L.Ed.2d 450 (1976)). As for redressability, it must be “likely, as opposed to merely speculative, that the injury will be redressed by a favorable decision.” Id. at 561, 112 S.Ct. 2130 (internal quotations and citation omitted). On appeal, Saitas does not appear to argue that Plaintiffs have not suffered an injury in fact or that they fail to demonstrate causation. Rather, Saitas focuses his challenge on the redressability requirement. Saitas argues that an injunctive order requiring him to classify the Deep-wood and South Loop 12 sites as “open dumps,” and to formally submit the names of those sites to the EPA for inclusion on the ODI, will not remedy the problem posed by the illegal dumps because there is no correlation between classification and enforcement. Saitas analogizes the instant case to Steel Co. Plaintiffs acknowledge that if they were seeking only to have the dumps classified as open dumps and listed on the ODI, then standing could be problematic, as in Steel Co. However, they interpret the RCRA not only to require Saitas to classify Deepwood and South Loop 12 as open dumps and submit them for the ODI, but also to require Saitas either to upgrade or to close the dumps. Thus, Plaintiffs assert that their requested relief goes beyond merely listing the Deepwood and South Loop 12 dumps on the ODI, noting that they strove to obtain an injunction that would also require Saitas to take steps to close the dumps or upgrade them to federal standards and to take the steps necessary to eliminate the existing health hazards and to minimize potential health hazards. We agree with Plaintiffs that they have standing. First, Plaintiffs have amply demonstrated an injury in fact. At least two-million cubic yards of waste, approximately forty-feet deep, are present at the Deepwood dump, which is adjacent to Plaintiffs’ residential neighborhoods. Residents close to the dumps report the appearance of snakes and rats in their backyards since the beginning of the illegal dumping. Asbestos and benzo(a)athracene have been detected at the Deepwood dump, and benzene has been discovered in excess 0/state limits. The Deepwood dump has caught fire and burned several times, and a significant fire hazard still exists at the dump. Solid waste continues to be dumped on the South Loop 12 site, with the State discovering during a 1991 inspection that the area of the waste along the alley behind the homes has been expanding. The City and State themselves have acknowledged that both dumps constitute a hazard to the public health. These facts, among others, demonstrate a concrete, actual injury and thus satisfy the first standing requirement. Next, we find that Plaintiffs have demonstrated causation. The district court found that because most dumps do not apply for a state permit, the State’s strategy of listing only previously permitted sites on the ODI “greatly reduced the number of existing open dumps in Texas that could potentially find their way onto the ODI.” The court also found that all of the dumps that the State did list on the ODI were subsequently upgraded to meet the EPA’s sanitary landfill criteria. From our review of the record, we find that the district court did not err in making these findings. Therefore, it can be said that Plaintiffs’ injury is “fairly traceable” to the actions of Saitas as it is likely that conditions at the Deepwood and South Loop 12 dumps would have been ameliorated if Sai-tas had acted to set the process in motion. Had the Deepwood and South Loop 12 dumps been placed on the ODI (which, Plaintiffs contend, is required by the RCRA), Saitas would have been obligated to plan for and implement the closing or upgrading of the dumps under 40 C.F.R. § 256.23. We also agree with Plaintiffs that Steel Co. is inapposite to the instant case and find that they have satisfied the redressa-bility requirement as well. In Steel Co., a citizens group sought declaratory judgment that the defendant violated the Emergency Planning and Community Right to Know Act (the “EPCRA”), 42 U.S.C. § 11046(a)(1), by failing to file timely annual emergency and hazardous chemical inventory forms. See Steel Co., 523 U.S. at 86-88, 118 S.Ct. 1003. Unlike the instant case, the Steel Co. defendant filed all of the overdue reports with the relevant agencies after receiving notice from the plaintiff that it was in violation of the EPCRA (even before the civil suit was filed). See id. at 88, 118 S.Ct. 1003. The Supreme Court itself subsequently noted this very distinction in Friends of the Earth, Inc. v. Laidlaw Environmental Services (TOC), Inc., 528 U.S. 167, 120 S.Ct. 693, 145 L.Ed.2d 610 (2000). The Court stated: We specifically noted in [Steel Co.] that there was no allegation in the complaint of any continuing or imminent violation, and that no basis for such an allegation appeared to exist. In short, Steel Co. held that private plaintiffs, unlike the Federal Government, may not sue to assess penalties for wholly past violations, but our decision in that case did not reach the issue of standing to seek penalties for violations that are ongoing at the time of the complaint and that could continue into the future if undeterred. Id. at 187-88, 120 S.Ct. 693 (internal citations omitted); see also 13 Chaeles Alan WRIGHT, AethuR R. Miller & Edward H. Cooper, Federal Practice and Procedure § 3531.10, at 868 (Supp.2000) (“Many aspects of the [ruling in Steel Co.] rested on the conclusion that the plaintiff could not achieve standing by seeking remedies that would advance the public interest in deterring future violations or punishing past violations.”). In this case, Saitas did not act to classify properly the Deepwood and South Loop 12 sites as open dumps and then execute the resulting upgrade/closure process after being informed by Plaintiffs of alleged violations of federal law (as the Steel Co. defendant had done). Plaintiffs have alleged longstanding and uncorrected violations of Saitas’s obligations to plan for and accomplish the elimination of the hazards caused by the dumps. Thus, an injunction requiring Saitas to upgrade or close the dumps would redress the hazards created by those dumps. See Meghrig, 516 U.S. at 484, 116 S.Ct. 1251 (stating that “a private citizen suing under § 6972(a)(1)(B) could seek a mandatory injunction, i.e., one that orders a responsible party to ‘take action’ by attending to the cleanup and proper disposal of toxic waste, or a prohibitory injunction, i.e., one that ‘restrains’ a responsible party from further violating [the] RCRA”); Sealy Conn., Inc. v. Litton Indus., Inc., 989 F.Supp. 120, 124 (D.Conn.1997) (stating that “mandatory injunctions are authorized by § 6972(a)(1)(B)” for attending to the cleanup and proper disposal of toxic waste); cf. United States v. Price, 688 F.2d 204, 214 (3d Cir.1982) (stating that § 6973, see supra note 22, “authorizes the cleanup of a site, even a dormant one, if that action is necessary to abate a present threat to the public health or the environment”); United States v. Valentine, 856 F.Supp. 627, 633 (D.Wyo.1994) (stating that “[i]t is plain ... that [§ 6973, see supra note 22,] empowers [a court] to grant the full range of equitable remedies and also all remedies traditionally provided under the common law of nuisance, at least so long as such relief serves to protect the public health and environment”). 2. The Eleventh Amendment Saitas argues on appeal that he is protected from suit by the Eleventh Amendment and that the suit cannot be maintained under Ex parte Young, 209 U.S. 123, 28 S.Ct. 441, 52 L.Ed. 714 (1908). The Eleventh Amendment states: “The Judicial power of the United States shall not be construed to extend to any suit in law or equity, commenced or prosecuted against one of the United States by Citizens of another State, or by Citizens or Subjects of any Foreign State.” U.S. Const, amend. XI. “Although by its terms the Amendment applies only to suits against a State by citizens of another State, ... the Amendment’s applicability [has been extended] to suits by citizens against their own States.” Bd. of Trustees of the Univ. of Ala. v. Garrett, 531 U.S. 356, 121 S.Ct. 955, 962, 148 L.Ed.2d 866 (2001). Because Plaintiffs have sued a state official in his official capacity, we address whether the doctrine of Ex parte Young operates in this case. As will be explained below, we find that Plaintiffs’ suit for prospective injunctive relief under the RCRA may proceed against the individual state official sued in his official capacity, Jeffrey A. Saitas, Executive Director of the TNRCC. Ex parte Young Ex parte Young held that the Eleventh Amendment does not bar a suit against a state official who is alleged to be acting in violation of federal law.
