This appeal addresses successor liability under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA), 42 U.S.C. § 9601 et seq., for environmental response costs incurred by the United States at a lead-contaminated Superfund site. The District Court granted summary judgment in favor of the United States on a "de facto merger" theory of successor liability. We will affirm.

The matter begins with a now defunct company, Price Battery Corporation. From the 1930s through 1966, Price Battery manufactured lead acid batteries at a plant in Hamburg, Pennsylvania. During that time, it arranged for the disposal of waste materials—including spent battery casings—at locations in and around Hamburg. In 1992, the United States Environmental Protection Agency discovered two of the disposal sites, and upon further investigation found three more. The properties contained elevated levels of lead. After testing and monitoring, the EPA concluded remedial action was necessary to protect human health. The United States has since incurred response costs of several million dollars associated with the removal of contaminated soil and the installation of a remedial "cap" at the properties.

Seeking to identify a responsible party under CERCLA, see 42 U.S.C. § 9607(a)(1)-(4), EPA determined that Price Battery, through its disposal of battery casings, was responsible for the lead contamination. Price Battery, however, was long since out of business, having been acquired for cash and stock by General Battery Corporation in 1966. General Battery, in turn, merged with Exide Corporation in 2000. The United States filed this action against Exide, alleging it was responsible for Price Battery's CERCLA liability as a successor in interest.

The parties agree that as a consequence of the 2000 merger, Exide is General Battery's successor. The disputed issue is whether General Battery, by virtue of its 1966 acquisition of Price Battery, was a successor to Price Battery. The relevant aspects of the Price/General transaction are as follows. On February 11, 1966, General Battery, a diversified public company, entered into an agreement with Price Battery, a smaller, privately-held battery manufacturing firm. Price Battery was owned by a single shareholder, William F. Price Sr., who sold General Battery most of his company's assets in exchange for $2.95 million in cash, 100,000 shares of General Battery stock, and a seat on General's board of directors.1 At the time, 100,000 General Battery shares were valued at approximately $1 million and represented 4.537% of General's outstanding equity. William Price Sr.'s resulting stake in General Battery was comparable to that of the company's cofounders, W.A. Shea and H.J. Nozensky, who in 1966 remained on General's board and held 5.12% and 4.44% of its outstanding equity, respectively.

Under the agreement, General Battery purchased Price Battery's equipment, materials, intellectual property and inventory. It also assumed Price Battery's contractual obligations, including employment contracts, and assumed all other liabilities appearing on Price Battery's balance sheet. General Battery indemnified Price Battery for claims, other than future tort claims, arising from Price Battery's operations, and agreed to continue the employment of three senior Price Battery officers—the president, the executive vice president, and the vice president of manufacturing.

After the transaction, General Battery continued manufacturing batteries at the Hamburg plant. Price Battery's plant superintendent and middle managers retained their positions, as did the union employees, office personnel and sales force. General Battery produced the same batteries that Price Battery had produced and honored Price Battery's contracts with existing customers and vendors. Price Battery, meanwhile, was required under the agreement to immediately change its name to Price Investment Company and to retain $150,000 in cash pending completion of an audit. The agreement contemplated that following the audit and any corresponding adjustment in the purchase price, Price Investment would liquidate on or before December 31, 1966. From the transaction closing in February of 1966 until filing for a certificate of corporate dissolution in February of 1967, Price Investment Company had no operations.

On cross-motions for summary judgment, the District Court held the Price/General transaction constituted a common law "de facto merger." In the District Court's view, the continuity of location, assets, products, operations, management, employees, contracts, and shareholders between Price Battery and General Battery, and the subsequent liquidation and dissolution of Price Battery, establish General Battery (and now Exide) as Price Battery's successors in interest under CERCLA. United States v. Exide Corp., 2002 WL 319940 (E.D.Pa. Feb. 27, 2002), 2002 U.S. Dist. LEXIS 3303. Following the District Court's entry of summary judgment, the parties stipulated to past CERCLA response costs at the Hamburg site in the amount of $6,500,000. Exide retained the right to file this appeal as to liability.

The District Court had jurisdiction under CERCLA, 42 U.S.C. § 9613(b), and 28 U.S.C. § 1331. We have jurisdiction under 28 U.S.C. § 1291. Our summary judgment standard of review is plenary. In re Mushroom Transp. Co., 382 F.3d 325, 335 (3d Cir.2004) (drawing all reasonable inferences in favor of the non-moving party).

We return, once again, to the difficult area of indirect liability under CERCLA.2 CERCLA is a "sweeping" federal remedial statute, enacted in 1980 to ensure that "everyone who is potentially responsible for hazardous-waste contamination may be forced to contribute to the costs of cleanup." United States v. Bestfoods, 524 U.S. 51, 56 n. 1, 118 S. Ct. 1876, 141 L. Ed. 2d 43 (1998) (quoting Pennsylvania v. Union Gas Co., 491 U.S. 1, 21, 109 S. Ct. 2273, 105 L. Ed. 2d 1 (1989) (plurality opinion of Brennan, J.)) (emphasis in original). "As its name implies, CERCLA is a comprehensive statute that grants the President broad power to command government agencies and private parties to clean up hazardous waste sites." Id. at 55, 118 S. Ct. 1876 (quoting Key Tronic Corp. v. United States, 511 U.S. 809, 814, 114 S. Ct. 1960, 128 L. Ed. 2d 797 (1994)).

CERCLA is not, however, "a model of legislative draftsmanship," Exxon Corp. v. Hunt, 475 U.S. 355, 363, 106 S. Ct. 1103, 89 L. Ed. 2d 364 (1986)—and successor liability is one of its puzzles. Although the statute fails to address the issue expressly, it is now settled that CERCLA incorporates common law principles of indirect corporate liability, including successor liability. See 42 U.S.C. § 9601(21) (including "corporations" among the "persons" covered by CERCLA); 1 U.S.C. § 5 (providing, as a rule of interpretation, that "the word `company' or `association', when used in reference to a corporation, shall be deemed to embrace the words `successors and assigns of such company or association'"); Bestfoods, 524 U.S. at 63-64, 118 S. Ct. 1876 (holding CERCLA incorporates common law of parent/subsidiary veil-piercing); Smith Land, 851 F.2d at 92 (holding CERCLA imposes successor liability).3

The threshold issue on appeal is whether to apply a uniform federal rule of successor liability, or whether to apply the law of a particular state. The second issue is whether Exide is liable as a successor.

We have previously addressed and decided the threshold issue. In Smith Land, we held that CERCLA successor liability is a matter of uniform federal law, as derived from "the general doctrine of successor liability in operation in most states." 851 F.2d at 92 (3d Cir.1988). Likewise, we held in Lansford-Coaldale that "given the federal interest in uniformity in the application of CERCLA, it is federal common law, and not state law, which governs" matters of indirect CERCLA liability. 4 F.3d at 1225 (3d Cir.1993) (discussing parent/subsidiary veil-piercing).

In the course of holding that CERCLA authorizes successor liability, we reasoned that "Congress expected the courts to develop a federal common law to supplement the statute," that "[i]n resolving the successor liability issues here, the district court must consider national uniformity," and that "[t]he general doctrine of successor liability in operation in most states should guide the court's decision rather than the excessively narrow statutes which might apply in only a few states." Smith Land, 851 F.2d at 91-92. This reasoning is unambiguous, essential to the Smith Land disposition, and controlling on the issue before us. Smith Land expressly rejected the position that a particular state's successor liability law applies under CERCLA. Lansford-Coaldale, another indirect liability case under CERCLA, is to the same effect. 4 F.3d at 1225. The Supreme Court has neither addressed nor disturbed these holdings. See Bestfoods, 524 U.S. at 64 n. 9, 118 S. Ct. 1876 (noting, but not resolving, disagreement over "whether, in enforcing CERCLA's indirect liability, courts should borrow state law, or instead apply a federal common law").

Relying principally on O'Melveny & Myers v. FDIC, 512 U.S. 79, 114 S. Ct. 2048, 129 L. Ed. 2d 67 (1994), a case decided under the federal banking statutes, and Davis, 261 F.3d at 54 (1st Cir.2001), a case applying state successor liability law under CERCLA, Exide invites us to overrule Smith Land.

In United States v. Kimbell Foods, Inc., 440 U.S. 715, 99 S. Ct. 1448, 59 L. Ed. 2d 711 (1979), the Supreme Court addressed the propriety of applying state law under an ambiguous or incomplete federal statute. The Court emphasized that, "[w]hether to adopt state law or to fashion a nationwide federal rule is a matter of judicial policy `dependant upon a variety of considerations always relevant to the nature of the specific governmental interests and to the effects upon them of applying state law.'" Id. at 728, 99 S. Ct. 1448 (quoting United States v. Standard Oil, 332 U.S. 301, 310, 67 S. Ct. 1604, 91 L. Ed. 2067 (1947)). The issue in Kimbell Foods was whether, absent an express statutory directive, a uniform federal rule of lien priorities was necessary under certain federal loan programs. Id. at 718, 99 S. Ct. 1448. Employing a three-factor analysis, the Court answered this question in the negative, holding state law governed the priority of the liens. Kimbell Foods considered (1) whether the federal program, by its very nature, required uniformity; (2) whether application of state law would frustrate specific objectives of the federal program; and (3) whether application of uniform federal law would disrupt existing commercial relationships predicated on state law. Id. at 728-29, 99 S. Ct. 1448.

Emphasizing the second Kimbell Foods factor—a conflict with an identifiable federal interest—the Supreme Court in O'Melveny cautioned against the unwarranted displacement of state law, holding that state rules of decision generally fill interstitial gaps in federal statutes. 512 U.S. at 87, 114 S. Ct. 2048. The displacement of state law is particularly disfavored in the area of corporate law, because business decisions typically proceed in reliance on the applicable state standards. Kamen v. Kemper Fin. Servs., Inc., 500 U.S. 90, 105, 111 S. Ct. 1711, 114 L. Ed. 2d 152 (1991). State corporation law generally should be integrated into the federal statutory regime, unless there exists "a significant conflict between some federal policy or interest and the use of state law." O'Melveny, 512 U.S. at 87, 114 S. Ct. 2048; see also Kamen, 500 U.S. at 107, 111 S. Ct. 1711; Kimbell Foods, 440 U.S. at 728, 99 S. Ct. 1448; see generally Henry J. Friendly, In Praise of Erie—And of the New Federal Common Law, 39 N.Y.U. L.Rev. 383 (1964). The principal question here, then, is whether CERCLA requires a uniform federal standard of corporate successor liability.

As noted, Smith Land and Lansford-Coaldale expressly held that CERCLA requires uniform federal standards of successor and veil-piercing liability, respectively. Neither case has been overruled. O'Melveny, a case brought under a state law cause of action (as opposed to a federal liability statute), 512 U.S. at 83, 114 S. Ct. 2048, dealing with the preemptive force of the federal banking statutes, id. at 86, 114 S. Ct. 2048, did not overrule our CERCLA-specific holdings in Smith Land and Lansford-Coaldale. O'Melveny involved claims brought by the Federal Deposit Insurance Corporation (FDIC), as the receiver of a federally insured bank, under California tort law. The FDIC argued, notwithstanding its reliance on a state law cause of action, that uniform federal liability standards should preempt the California rules of decision. The Supreme Court disagreed, holding the relevant federal statutes neither authorized nor required the creation of a preemptive body of federal common law in cases arising under state law causes of action. Id. at 89, 114 S. Ct. 2048. Atherton v. FDIC, another decision cited by Exide Corporation in which the Court cautioned against the unwarranted "creation" of federal common law, also involved the preemptive scope of the federal banking laws. 519 U.S. 213, 218, 117 S. Ct. 666, 136 L. Ed. 2d 656 (1997).

Smith Land and Lansford-Coaldale, in contrast, held that uniform standards of indirect corporate liability are necessary under CERCLA, an environmental liability statute enforced under its own federal cause of action. O'Melveny and Atherton neither addressed the CERCLA-specific reasoning of Smith Land and Lansford-Coaldale nor overruled their CERCLA-specific holdings.

Bestfoods, a case decided after O'Melveny and Atherton, is the only Supreme Court decision touching on the CERCLA question at issue. But the Court there explicitly declined to resolve the circuit split on whether CERCLA borrows a particular state's law of indirect corporate liability. Bestfoods, 524 U.S. at 64 n. 9, 118 S. Ct. 1876. Bestfoods neither cited O'Melveny nor otherwise suggested that uniform CERCLA successor liability standards were inappropriate.

If anything, Bestfoods cuts in favor of a uniform federal standard. Bestfoods applied "fundamental" and "hornbook" principles of indirect corporate liability, not the law of any particular state. 524 U.S. at 61-62, 118 S. Ct. 1876. The court of appeals in Bestfoods had applied Michigan law. United States v. Cordova Chem. Co., 113 F.3d 572, 580 (6th Cir.1997) (en banc). But the Supreme Court declined to apply Michigan law and instead looked to the general "hornbook" rule of veil-piercing. The Court's reliance on the general standard is a different matter than borrowing the law of a particular state. Applying a particular state's law requires a state-by-state interpretation of the federal liability statute—a result, in the case of successor liability under CERCLA, that we believe conflicts with the statutory objectives. See discussion infra.

A uniform federal standard is also consistent with recent Supreme Court decisions in which gaps in federal liability statutes were filled not with the law of a particular state, but with general common law principles. Clackamas Gastroenterology Assocs., P.C. v. Wells, 538 U.S. 440, 448, 123 S. Ct. 1673, 155 L. Ed. 2d 615 (2003) (looking to the general common law definition of "servant" to define the term "employee" under the ADA); Burlington Indus., Inc. v. Ellerth, 524 U.S. 742, 754, 118 S. Ct. 2257, 141 L. Ed. 2d 633 (1998) (relying on "the general common law of agency, rather than on the law of any particular State," in defining the term "agent" under Title VII) (citation omitted). Just as the ADA and Title VII require uniform federal definitions of the terms "employee" and "agent," respectively, CERCLA requires a uniform federal definition of "successor corporation." As the Court explained in Burlington, "[t]he resulting federal rule, based on a body of case law developed over time, is statutory interpretation pursuant to congressional direction," not the free-wheeling creation of federal common law. 524 U.S. at 755, 118 S. Ct. 2257.

For these reasons, we believe that Smith Land and Lansford-Coaldale have not been undermined by recent Supreme Court decisions and remain circuit law. See Third Circuit Internal Operating Procedure 9.1 ("[T]he holding of a panel in a precedential opinion is binding on subsequent panels. Thus, no subsequent panel overrules the holding in a precedential opinion of a previous panel. Court en banc consideration is required to do so.").

Moreover, we believe Smith Land is consistent with CERCLA's objectives. CERCLA is a federal liability statute, applicable nationwide to those responsible for hazardous-waste contamination. Liability under the statute is a matter of federal law. 42 U.S.C. § 9613(f)(1) (CERCLA contribution actions "shall be governed by Federal law"); Kimbell Foods, 440 U.S. at 726, 99 S. Ct. 1448 ("This Court has consistently held that federal law governs questions involving the rights of the United States arising under nationwide federal programs.").

It is true that successor tort liability, including successor environmental liability, rests at the intersection of tort and corporate law—both areas largely regulated by the states. But it does not necessarily follow that CERCLA's statutory scheme is served by borrowing a particular state's successor liability law as the federal rule of decision. The choice of law framework governing successor liability remains unsettled.4 And although the general doctrine of successor liability is "largely uniform" under state law, Atchison, 159 F.3d at 363 (9th Cir.1997) (citation omitted), this uniformity is less apparent when the general standards are applied in specific cases.5 Beneath a veneer of uniformity, the "entire issue of successor liability ... is dreadfully tangled, reflecting the difficulty of striking the right balance between the competing interests at stake." EEOC v. Vucitech, 842 F.2d 936, 944 (7th Cir.1988).

In Atchison, the Court of Appeals for the Ninth Circuit, in considered dictum, expressed doubt that a uniform federal rule of successor liability is necessary under CERCLA. 159 F.3d at 364. The court reasoned that "[i]f state law varied widely on the issue of successor liability, perhaps the need for a uniform federal rule would be more apparent." Id. at 363. But we respectfully disagree with Atchison's premise. State law does vary substantially on the issue of successor liability, and its unpredictability counsels in favor of CERCLA uniformity.

The successor liability issues raised in this case are illustrative. Whether a mixed cash/stock acquisition triggers successor liability under the de facto merger doctrine does not command uniform treatment among the states.6 Whether successor liability attaches to a transaction where the seller receives a "small percentage" of the buyer's outstanding equity is also unsettled.7 For example, New Jersey corporations may be held responsible for successor environmental liability from which New York corporations may be exempt. Compare PSC, 175 N.J.Super. 447, 419 A.2d 1151 (1980) (applying expansive theory of successor liability to environmental torts), with Schumacher v. Richards Shear Co., 59 N.Y.2d 239, 464 N.Y.S.2d 437, 451 N.E.2d 195, 198 (1983) (adhering to traditional concepts of successor liability). We doubt Congress intended to incorporate such variations under a comprehensive federal liability statute. See 42 U.S.C. § 9613(f)(1) (CERCLA contribution actions "shall be governed by Federal law"); Miss. Band of Choctaw Indians v. Holyfield, 490 U.S. 30, 43, 109 S. Ct. 1597, 104 L. Ed. 2d 29 (1989) ("federal statutes are generally intended to have uniform nationwide application").

A more uniform and predictable federal liability standard corresponds with specific CERCLA objectives by encouraging settlements and facilitating a more liquid market in corporate and "brownfield" assets. See 42 U.S.C. § 9622 (encouraging CERCLA settlements "in order to expedite effective remedial actions and minimize litigation"); § 9607(r) (encouraging transfer and redevelopment of contaminated property under CERCLA's so-called "Brownfield Amendments");8 cf. Polius v. Clark Equip. Co., 802 F.2d 75, 83 (3d Cir.1986) ("Unforseeable alterations in successor liability principles complicate transfers and necessarily increases transaction costs. Major economic decisions, critical to society, are best made in a climate of relative certainty and reasonable predictability.") (citation omitted).

Smith Land's application of the "majority" standard fosters CERCLA predictability. It also accords respect to existing commercial relationships predicated on the majority state law, cf. Kimbell Foods, 440 U.S. at 728-29, 99 S. Ct. 1448, while ensuring that responsible parties, including successor corporations, contribute their fair share to the cleanup of hazardous waste under the federal program. Accord B.F. Goodrich v. Betkoski, 112 F.3d 88 (2d Cir.1997) (applying uniform federal standard); Carolina Transformer, 978 F.2d at 837 (4th Cir.1992) (same); Mex. Feed & Seed, 980 F.2d at 487 n. 9 (8th Cir.1992) (dicta); but see Davis, 261 F.3d at 54 (1st Cir.2001) (applying state law); Atchison, 159 F.3d at 361-64 (9th Cir.1997) (dicta); Anspec, 922 F.2d at 1250 (6th Cir.1991) (Kennedy, J., concurring).

Davis, the most recent court of appeals decision applying state law, held that CERCLA incorporates state successor liability rules unless the particular state law is "hostile to the federal interests animating CERCLA." 261 F.3d at 54 (1st Cir.2001). Davis followed Atchison, where the Court of Appeals for the Ninth Circuit concluded that borrowing state law is consistent with CERCLA, because "[i]t is unrealistic to think that a state would alter general corporate law principles to become a particularly hospitable haven for polluters." 159 F.3d at 364 (9th Cir.1997). As a general matter, we agree it is unlikely that states would attempt to immunize their corporations from CERCLA liability. See generally Richard L. Revesz, Rehabilitating Interstate Competition: Rethinking the "Race to the Bottom" Rationale for Federal Environmental Regulation, 67 N.Y.U. L.Rev. 1210 (1992).

But neither Atchison, nor Davis, nor the concurring and dissenting opinion, address the conflict between CERCLA's objectives and borrowing unpredictable state successorship law. We believe that incorporating variable and uncertain state successor liability standards would increase significantly CERCLA litigation and transaction costs—in conflict with the statutory interests embodied in 42 U.S.C. § 9622, which aims to encourage early settlements, and § 9607(r), which aims to facilitate a liquid market in brownfield assets. See In re Tutu Water Wells CERCLA Litig., 326 F.3d 201, 206 (3d Cir.2003) (emphasizing CERCLA's policy of minimizing litigation costs); United States v. DiBiase, 45 F.3d 541, 545-46 (1st Cir.1995) (explaining CERCLA's policy of reducing "transaction costs"); see generally United States v. Charter Int'l Oil Co., 83 F.3d 510, 520 (1st Cir.1996) (surveying empirical research on the "huge resources going into the transactions costs of CERCLA litigation" and observing that reducing these costs was a primary objective of the 1986 amendments to the statute).

To summarize, the Supreme Court has neither overruled nor directly undermined Smith Land. Furthermore, a uniform federal standard is appropriate under Kimbell Foods and O'Melveny: (1) the nature of the federal program, a comprehensive federal liability statute, counsels in favor of national uniformity; (2) a uniform successor liability standard is necessary to advance CERCLA's remedial objectives and to facilitate a fluid market in corporate and brownfield assets; and (3) uniform application of the majority state standard accords proper respect to commercial relationships predicated on the majority state law. Therefore, we will apply "the general doctrine of successor liability in operation in most states." Smith Land, 851 F.2d at 92.

The concurring and dissenting opinion contends that we reach an "unnecessary" holding on this issue, emphasizing that Pennsylvania law mirrors the majority "de facto merger" standard and would yield the same result. But Smith Land and Lansford-Coaldale preclude exclusive reliance on the law of a particular state. For the reasons stated, we believe these decisions remain controlling. More fundamentally, because CERCLA's goal of minimizing litigation and transaction costs is ill-served by a case-by-case approach to the question of successor liability choice-of-law, we need not inquire whether Pennsylvania law conflicts with or mirrors the majority successor liability doctrine before holding that a federal rule applies.

We add a final note on nomenclature and its pitfalls. Part of the difficulty in this area may stem from imprecise use of the term "federal common law." In its strictest sense, federal common law represents the judicial "creation" of law under a generalized statutory mandate. Atherton, 519 U.S. at 218, 117 S. Ct. 666. Examples include the federal labor laws, Textile Workers Union v. Lincoln Mills, 353 U.S. 448, 77 S. Ct. 912, 1 L. Ed. 2d 972 (1957), and ERISA, Firestone Tire & Rubber Co. v. Bruch, 489 U.S. 101, 110, 109 S. Ct. 948, 103 L. Ed. 2d 80 (1989). In recent years the Supreme Court has emphasized that the cases requiring this brand of federal common law are "few and restricted." O'Melveny, 512 U.S. at 87, 114 S. Ct. 2048 (citation omitted). To view every ambiguous federal statute as authorizing an expansive body of "federal common law" would be an invitation to federal courts to eviscerate both the Erie doctrine and the concept of dual sovereignty it embodies.

But the "creation" of federal common law must be distinguished from statutory interpretation. See Atherton, 519 U.S. at 218, 117 S. Ct. 666. Ambiguous federal statutes generally do not authorize the creation of a new (and preemptive) body of federal law. Id. But this principle does not require that every federal statutory gap be filled by way of state-by-state interpretation. "In almost any statutory scheme, there may be a need for judicial interpretation of ambiguous or incomplete provisions. But the authority to construe a statute is fundamentally different from the authority to fashion a new rule or to provide a new remedy which Congress has decided not to adopt." Northwest Airlines, Inc. v. Transp. Workers Union, 451 U.S. 77, 97, 101 S. Ct. 1571, 67 L. Ed. 2d 750 (1981); see also Atherton, 519 U.S. at 218, 117 S. Ct. 666 (distinguishing the "creation" of federal common law from "interpretation of a federal statute or a properly promulgated administrative rule").

In the case of federal liability statutes enforced under a federal cause of action, the law is generally intended to have uniform nationwide application. Cmty. for Creative Non-Violence v. Reid, 490 U.S. 730, 740, 109 S. Ct. 2166, 104 L. Ed. 2d 811 (1989) ("federal statutes are generally intended to have uniform nationwide application"); Jansen v. Packaging Corp., 123 F.3d 490, 507 (7th Cir.1997) (en banc) (Posner, J., concurring and dissenting). The most recent Supreme Court cases, both decided after O'Melveny and Atherton, followed this approach. Clackamas, 538 U.S. at 448, 123 S. Ct. 1673 (2003); Burlington, 524 U.S. at 754-55, 118 S. Ct. 2257 (1998). These decisions affirm the view that uniform interpretation of an undefined term in a federal liability statute "is not free-wheeling common-law rulemaking," but rather "filling a statutory gap, a standard office of interpretation." Jansen, 123 F.3d at 507. Accordingly, supplying a uniform definition of "successor corporation" under CERCLA is a matter of interpreting the federal statute. See 42 U.S.C. § 9601(21) (including "corporations" among the "persons" covered by CERCLA); 1 U.S.C. § 5 (providing, as a rule of interpretation, that "the word `company' or `association', when used in reference to a corporation, shall be deemed to embrace the words `successors and assigns of such company or association'").

Turning to the appropriate liability standard, we are mindful of Bestfoods, where the Supreme Court held that CERCLA incorporates, but does not expand upon, "fundamental" common law principles of indirect corporate liability. 524 U.S. at 62-64, 118 S. Ct. 1876. The general rule of corporate successorship accepted in most states is non-liability for acquiring corporations, with the following exceptions:

The purchaser may be liable where: (1) it assumes liability; (2) the transaction amounts to a consolidation or merger; (3) the transaction is fraudulent and intended to provide an escape from liability; or (4) the purchasing corporation is a mere continuation of the selling company.

Polius, 802 F.2d at 78 (3d Cir.1986) (stating general rule); 15 William Meade Fletcher et al., Fletcher Cyclopedia of the Law of Private Corporations § 7122, at 227-48 (perm.ed., rev.vol.1999) (collecting cases).

This case involves the "de facto merger" exception, which has four elements under the majority standard. It applies where:

(1) There is a continuation of the enterprise of the seller corporation, so that there is a continuity of management, personnel, physical location, assets, and general business operations.

(2) There is a continuity of shareholders which results from the purchasing corporation paying for the acquired assets with shares of its own stock, this stock ultimately coming to be held by the shareholders of the seller corporation so that they become a constituent part of the purchasing corporation.

(3) The seller corporation ceases its ordinary business operations, liquidates, and dissolves as soon as legally and practically possible.

(4) The purchasing corporation assumes those obligations of the seller ordinarily necessary for the uninterrupted continuation of normal business operations of the seller corporation.

Bud Antle, Inc. v. Eastern Foods, Inc., 758 F.2d 1451, 1457-58 (11th Cir.1985) (stating the "majority" de facto merger standard); Keller v. Clark Equip. Co., 715 F.2d 1280, 1291 (8th Cir.1983) (same); 15 Fletcher, supra, § 7124.20, at 302 (stating majority rule and collecting cases). The majority standard generally tracks the inquiry under Pennsylvania law. See SmithKline Beecham, 89 F.3d at 162 n. 6.

Based on the record, we agree with the District Court that the Price/General transaction constituted a de facto merger.

(1)

Under prong one—continuity of enterprise—General Battery purchased all of Price Battery's equipment and inventory, assumed tenancy of its manufacturing plant, and continued its production of batteries. The plant superintendent and middle managers retained their positions, as did the union employees, office personnel and sales force. General Battery continued the employment of three senior Price Battery executives—the president, executive vice president, and vice president of manufacturing—who, among other duties, remained active in supervising the Hamburg plant. General Battery was supplied by Price Battery's vendors, served Price Battery's customers, and manufactured essentially the same battery products. In every operational respect—from management and employees to location and assets to products and general business operations—General Battery continued the Price Battery enterprise. We agree with the District Court's exemplary analysis under this element.

(2)

De facto merger prong two—continuity of shareholders—presents a closer question. Prior to the transaction, William Price Sr. was the sole shareholder of Price Battery. He received from General Battery $2.95 million in cash, 100,000 shares of General Battery stock, and a seat on General Battery's board of directors in exchange for the Price Battery enterprise. At the time, 100,000 shares of General Battery stock were valued at approximately $1 million and represented 4.537% of its outstanding equity. Price Sr.'s resulting stake in General Battery was comparable to that of the company's two co-founders, who owned 5.12% and 4.44% of its stock, respectively.

The parties dispute whether this mixed cash/stock transaction evidences the requisite continuity of ownership. Exide contends continuity of ownership is lacking where the seller receives "primarily" cash and a "small percentage" of the buyer's outstanding equity. The United States responds that "under the de facto merger exception, there is no requirement that the seller acquire majority control or any other specific percentage of the buyer, only that there be some continuity of shareholder ownership."

The standard applied in most states recognizes continuity of ownership where "the shareholders of the seller corporation ... become a constituent part of the purchasing corporation." 15 Fletcher, supra, § 7124.20, at 302 (stating general rule); Keller, 715 F.2d at 1291 (8th Cir.1983) (same); see also SmithKline Beecham, 89 F.3d at 162 n. 6 (3d Cir.1996) (Pennsylvania law).

This standard, which requires continuity rather than identity of ownership, corresponds with the general purposes of the successor liability doctrine. See Cargo Partner AG, 352 F.3d at 47 (2d Cir.2003) (New York law) (holding continuity of ownership "is the essence of" a de facto merger); Nat. Gypsum Co. v. Cont. Brands Corp., 895 F. Supp. 328, 337-38 (D.Mass.1995) (collecting cases). The overriding goal of successor liability, and of the de facto merger inquiry, is to balance "the interest in preventing tortfeasors from externalizing the costs of their misconduct" with "the interest in a fluid market in corporate assets." Vucitech, 842 F.2d at 944 (7th Cir.1988).

The continuity of shareholders element is designed to identify situations where the shareholders of a seller corporation retain some ownership interest in their assets after cleansing those assets of liability. See generally Marie T. Reilly, Making Sense of Successor Liability, 31 Hofstra L.Rev. 745 (2003); Mark J. Roe, Mergers, Acquisitions and Tort: A Comment on the Problem of Successor Corporation Liability, 70 Va. L.Rev. 1559 (1984). Successor liability in this context accords a legal remedy to injured third-parties, preventing the externalization of the seller's costs of doing business, and deterring transactions designed to impose the costs of misconduct on third-parties. See SmithKline Beecham, 89 F.3d at 164 (discussing remedial purposes of de facto merger doctrine). Identifying these transactions is the objective of the continuity of ownership requirement. Nat'l Gypsum, 895 F.Supp. at 337 (D.Mass.1995); Cargo Partner AG, 352 F.3d at 47 (2d Cir.2003).

But the cases do not, as Exide contends, distinguish sharply between transactions "primarily" for cash versus stock, or between large versus small percentage interests in the ongoing enterprise. Rather, only some continuity of ownership is required. There is no generally accepted common law distinction between primarily stock mergers, on the one hand, and primarily cash transactions, on the other.9 Nor does successor liability necessarily turn on the seller's percentage interest in the buyer.10 Although the "majority" standard is somewhat unsettled at this frontier of successor liability, the critical "continuity of ownership" inquiry appears to be whether the owners retained some ongoing interest in their assets.

Continuity of ownership is established under CERCLA where the owners of the predecessor enterprise become a "constituent part" of the successor by retaining some ongoing interest in their assets. See 15 Fletcher, supra, § 7124.20, at 302 (stating majority rule and collecting cases). Under this standard, William Price Sr. became a "constituent part" of General Battery when he received 100,000 shares of General Battery stock and a seat on General's board in exchange for the Price Battery enterprise.

(3)

Under the third de facto merger element, it is apparent that Price Battery ceased operations, liquidated, and dissolved as soon as legally and practically possible. The Price/General agreement, which closed in February of 1966, required Price Battery to discontinue operations immediately and change its name to Price Investment Company. Price Battery did so. The agreement also required that Price Investment remain in existence from February through December of 1966, maintaining cash reserves pending completion of an audit and other contingencies. After this waiting period and following any adjustments in the purchase price, the agreement contemplated that Price Battery would liquidate and dissolve. Specifically, the contract provided "for the complete liquidation of Price and the distribution of all of its assets within the twelve month period beginning [on February 8, 1966]." Price Investment filed for corporate dissolution on February 8, 1967, and formally dissolved approximately six months later.

The contractual requirement that Price Battery immediately change its name, cease operations, and subsequently liquidate and dissolve, is more characteristic of a merger than an asset purchase. As recognized under the de facto merger doctrine, an essential characteristic of a merger is that one corporation survives while another ceases to exist. Knapp v. N. Am. Rockwell Corp., 506 F.2d 361, 367 (3d Cir.1974) (Pennsylvania law). Here, the Price/General agreement expressly required the liquidation and dissolution of Price Battery as a condition of the transaction, suggesting a merger rather than the mere sale of Price Battery's assets.

Exide emphasizes Price Investment's failure to dissolve immediately, contending that for over a year "the two companies remained completely independent of each other in management and operations." But the more salient fact is that Price Battery immediately ceased ordinary business operations. Within one week of the closing date, Price Battery recast itself as Price Investment Company—a corporate shell that only held cash reserves pending final settlement with General Battery. Price Investment had no operations.

The Knapp case presented similar facts. There we held the seller company dissolved as soon as legally and practically possible. 506 F.2d at 369 (3d Cir.1974) (Pennsylvania law). The seller corporation in Knapp had "technically continued to exist until its dissolution approximately 18 months after the consummation of the transaction," id. at 364, but during that period it "had no substance" and "could not undertake any active operations." Id. at 369. As in Knapp, "barren continuation" of the seller company does not bar application of the de facto merger doctrine. Id. at 368. We agree with the District Court that Price Battery ceased operations, liquidated and dissolved as soon as legally and practically possible.

(4)

Finally, under prong four—assumption of obligations ordinarily necessary for the uninterrupted continuation of normal business operations—the Price/General agreement expressly provided that General Battery would assume Price Battery's contractual obligations and all other obligations appearing on Price Battery's balance sheet. This unambiguous assumption of obligations, including employment, sales and vendor contracts, satisfies the fourth de facto merger element.

In sum, the de facto merger criteria are satisfied. Citing Polius, Exide responds with the overarching objection that "imposition of successor liability on a purchasing company long after the transfer of assets defeats the legitimate expectations the parties held during negotiation and sale." 802 F.2d at 83. But even if we accept this statement as a general proposition, the response here is twofold. First, application of the traditional de facto merger standard, which generally tracks the Pennsylvania rule, can hardly come as a surprise to sophisticated corporate parties who transacted under Pennsylvania law. Second, CERCLA by its very nature upsets party expectations. Congress nevertheless viewed retroactive CERCLA liability as necessary to ensure that those "responsible for any damage, environmental harm, or injury from chemical poisons may be tagged with the cost of their actions." Bestfoods, 524 U.S. at 56, 118 S. Ct. 1876 (quoting S.Rep. No. 96-848, 13 (1980)) (internal punctuation marks omitted).

We hold that General Battery and Exide, as successors to Price Battery, are responsible for the CERCLA liability of their predecessor.

We briefly address the District Court's alternative holding that Exide is liable under CERCLA on a "substantial continuity" theory of successor liability.11 Prior to Bestfoods, several courts adopted the "substantial continuity" test as a basis for CERCLA successor liability. See N.Y. v. Nat'l Serv. Indus., 352 F.3d 682, 687-88 (2d Cir.2003) (collecting cases). "Substantial continuity" eliminates certain elements of the de facto merger analysis—including the continuity of ownership requirement—and in effect creates a more expansive rule of liability than is accepted in most states. Id. at 687 (noting substantial continuity is applied "by only a handful of states"). Recently, however, several courts of appeals have rejected the doctrine as inconsistent with Bestfoods, 524 U.S. 51, 118 S. Ct. 1876, 141 L. Ed. 2d 43 (1998).12 We agree. Bestfoods held that CERCLA does not, sub silentio, abrogate fundamental common law principles of indirect corporate liability. 524 U.S. at 63-64, 118 S. Ct. 1876. Accordingly, "substantial continuity" is untenable as a basis for successor liability under CERCLA.

We will affirm the judgment of the District Court.

RENDELL, Circuit Judge, Concurring in part and dissenting in part.

I agree with the majority's conclusion that the fact pattern presented was a de facto merger such that successor liability for purposes of CERCLA exists and therefore concur in its ultimate ruling. However, I part company with the majority regarding its decision to announce that the issue of successor liability in this context is controlled by federal common law. This determination is unnecessary to the resolution of the issues before us and runs counter to recent Supreme Court pronouncements which both call into question the concept of federal common law and explicitly state that only in the most limited of circumstances should we look beyond applicable state law. Moreover, two other courts of appeals — the First and the Ninth — have considered the precise issue before us and our opinion perpetuates a split among the courts of appeals. Those courts have opined that the Supreme Court's recent directives cast serious doubt on the advisability of creating federal common law to dictate the contours of successor liability under CERCLA.13 The majority, however, embraces the application of federal common law, relying instead on the outdated notion of promoting uniformity.

Over the course of the last decade, and since we decided Smith Land & Improv. Corp. v. Celotex Corp., 851 F.2d 86 (3d Cir.1988) and Lansford-Coaldale Joint Water Auth. v. Tonolli Corp., 4 F.3d 1209 (3d Cir.1993), the Supreme Court has issued several opinions denouncing the creation of federal common law where state law would otherwise apply. Principally, in O'Melveny & Myers v. FDIC, 512 U.S. 79, 114 S. Ct. 2048, 129 L. Ed. 2d 67 (1994), the Court rejected the notion that a federal common law rule regarding the imputation of corporate officer knowledge to a corporation should be applied in an action against the Federal Deposit Insurance Corporation ("FDIC"). The Court stated:

The first of these contentions need not detain us long, as it is so plainly wrong. "There is no federal general common law, and ... the remote possibility that corporations may go into federal receivership is no conceivable basis for adopting a special federal common-law rule divesting states of authority over the entire law of imputation."

Id. at 83, 114 S. Ct. 2048 (internal citation omitted) (citing Bank of America Nat. Trust & Sav. Assn. v. Parnell, 352 U.S. 29, 33-34, 77 S. Ct. 119, 1 L. Ed. 2d 93 (1956)).

The O'Melveny Court went on to note that, with regard to "the central question of displacement of [state] law" in favor of a rule federal in nature:

[W]e of course would not contradict an explicit federal statutory provision. Nor would we adopt a court-made rule to supplement federal statutory regulation that is comprehensive and detailed; matters left unaddressed in such a scheme are presumably left subject to the disposition provided by state law.

* * *

.... As we proceed to explain, even assuming the inapplicability of FIRREA [Financial Institutions Reform, Recovery, and Enforcement Act of 1989] this is not one of those cases in which judicial creation of a special federal rule would be justified.

Such cases are, as we have said in the past, "few and restricted," Wheeldin v. Wheeler, 373 U.S. 647, 651, 83 S. Ct. 1441, 10 L. Ed. 2d 605 (1963), limited to situations where there is a "significant conflict between some federal policy or interest and the use of state law." Wallis v. Pan American Petroleum Corp., 384 U.S. 63, 68, 86 S. Ct. 1301, 16 L. Ed. 2d 369 (1966). Our cases uniformly require the existence of such a conflict as a precondition for recognition of a federal rule of decision. Kimbell Foods, 440 U.S. at 728, 99 S. Ct. 1448. Not only the permissibility but also the scope of judicial displacement of state rules turns upon such a conflict. What is fatal to respondent's position in the present case is that it has identified no significant conflict with an identifiable federal policy or interest.

O'Melveny & Myers, 512 U.S. at 85, 87-88, 114 S. Ct. 2048 (some internal citations omitted) (emphasis added). While O'Melveny did not involve CERCLA, nonetheless, the pronouncement of the Court regarding displacement of state law makes crystal clear that matters left unaddressed by a comprehensive federal statutory scheme are presumably left subject to the disposition provided by state law14 — there must exist a conflict, identifiable and specific, with an important federal policy before we consider resorting to federal common law.

Three years after deciding O'Melveny, the Supreme Court again commented on the concept of "federal common law," in the case of Atherton v. FDIC, 519 U.S. 213, 117 S. Ct. 666, 136 L. Ed. 2d 656 (1997). In Atherton, the Court again emphasized the "precondition," id. at 218, 117 S. Ct. 666, that a conflict exist to warrant the conception of a federal rule; under the facts of the case before it, the Court stated that its initial inquiry must concern whether the application of the relevant state law standard of care to banks would conflict with, and thereby significantly undermine, an identifiable federal policy or interest:

States normally look to the State of a business' incorporation for the law that provides the relevant corporate governance general standard of care. And by analogy, it has been argued, courts should look to federal law to find the standard of care governing officers and directors of federally chartered banks.

To find a justification for federal common law in this argument, however, is to substitute analogy or formal symmetry for the controlling legal requirement, namely, the existence of a need to create federal common law arising out of a significant conflict or threat to a federal interest. O'Melveny, 512 U.S. at 85, 87, 114 S. Ct. 2048.

* * *

In sum, we can find no significant conflict with, or threat to, a federal interest. The federal need is far weaker than was present in what the Court has called the "few and restricted' instances," Milwaukee v. Illinois, 451 U.S. 304, 313, 101 S. Ct. 1784, 68 L. Ed. 2d 114 (1981), in which this Court has created a federal common law.

Atherton, 519 U.S. at 224-25, 117 S. Ct. 666. The Court then detailed such "few and restricted" cases, which I list in the margin.15 Again, the Court's focus was on the presence of a significant conflict. And, to discern whether a conflict is present, we are not to evaluate the jurisprudential landscape of all fifty states; rather, "federal courts should incorporate state law into federal common law unless the particular state law in question is inconsistent with the policies underlying the federal statute." Kamen v. Kemper Fin. Servs., 500 U.S. 90, 111 S. Ct. 1711, 1722, 114 L. Ed. 2d 152 (1991) (emphasis added).

Most recently, in United States v. Bestfoods, the Court was called upon to consider whether a parent corporation that actively participated in, and exercised control over, the operations of a subsidiary may, without more, be held liable under CERCLA as an operator of a polluting facility owned or operated by the subsidiary. 524 U.S. 51, 55, 118 S. Ct. 1876, 141 L. Ed. 2d 43 (1998). The Court answered in the negative, "unless the corporate veil may be pierced." Id. In so concluding, the Court expounded upon certain general principles of corporate law — for example, that parents are not liable for the acts of their subsidiaries, id. at 62, 118 S. Ct. 1876, along with the "equally fundamental principle of corporate law" that a corporate veil may be pierced where the corporate form was misused, id. Significantly, the Court explained:

Nothing in CERCLA purports to rewrite this well-settled rule, either. CERCLA is thus like many another congressional enactment in giving no indication "that the entire corpus of state corporation law is to be replaced simply because a plaintiff's cause of action is based upon a federal statute," Burks v. Lasker, 441 U.S. 471, 478, 99 S. Ct. 1831, 60 L. Ed. 2d 404 (1979), and the failure of the statute to speak to a matter as fundamental as the liability implications of corporate ownership demands application of the rule that "in order to abrogate a common-law principle, the statute must speak directly to the question addressed by the common law," United States v. Texas, 507 U.S. 529, 534, 113 S. Ct. 1631, 123 L. Ed. 2d 245 (1993) (internal quotation marks omitted). The Court of Appeals was accordingly correct in holding that when (but only when) the corporate veil may be pierced, may a parent corporation be charged with derivative CERCLA liability for its subsidiary's actions.

Id. at 63-64, 118 S. Ct. 1876 (footnotes omitted).

As noted by the majority, the Bestfoods Court declined to reach the precise issue before us, noting a "disagreement" as to whether "courts should borrow state law, or instead apply a federal common law of veil piercing," 524 U.S. at 64, n. 9, 118 S. Ct. 1876, but sidestepping any conclusion: "Since none of the parties challenges the Sixth Circuit's holding that [certain companies] incurred no derivative liability, the question is not presented in this case, and we do not address it further," id. The majority protests that the Court did not declare the use of federal common law inappropriate at this juncture or cite to O'Melveny. But the Court clearly did not need to, or choose to, reach the issue. We should infer nothing from its silence.

I find more significant the Bestfoods Court's affirmative discussion of "norms of corporate behavior," which it viewed as constituting crucial reference points, along with the reliability of bedrock principles of corporate law. See, e.g., 524 U.S. at 70 n. 13 & 71, 118 S. Ct. 1876. I cannot help but conclude that reference to the "norms" bolsters the view that existing state corporate law principles should control, and we need not invent federal law, or deem them "federal", in order to further CERCLA's regulatory scheme. The Court's discussion of "congressional silence" concerning these "bedrock" corporate principles, which it describes as "audible," supports this view. 524 U.S. at 62, 118 S. Ct. 1876. With respect to the silence wrought by Congress' failure to address, in the statute, the claim at issue in Bestfoods, notably, the Court stated that "CERCLA is thus like many another congressional enactment in giving no indication `that the entire corpus of state corporation law is to be replaced simply because the plaintiff's cause of action is based upon our federal statute.'" Bestfoods, 524 U.S. at 63, 118 S. Ct. 1876 (quoting Burks v. Lasker, 441 U.S. 471, 478, 99 S. Ct. 1831, 60 L. Ed. 2d 404 (1979)). Indeed, the Bestfoods Court chided the district court in that case for having "treated CERCLA as though it displaced or fundamentally altered common law standards of limited liability" because "such a rule does not arise from congressional silence, and CERCLA's silence is dispositive." 524 U.S. at 70, 118 S. Ct. 1876. Finally, it bears noting that the Supreme Court affirmed the court of appeals' determination applying Michigan law that a parent may be held liable only where the corporate veil may be pierced. See United States v. Cordova Chem. Co., 113 F.3d 572, 580 (6th Cir.1997).

After reading these three recent Supreme Court opinions, I am left with the clear impression that the notion of resorting to a federal rule of successor liability here, mandating it as controlling in our Circuit without regard to state law, would not be endorsed by the Supreme Court. The overarching theme is that state law should not be displaced unless the particular state law at issue conflicts with an important federal policy. Noticeably absent is any reference to the majority's guiding theme — that of the need for uniformity. And, as I discuss more fully below, uniformity for uniformity's sake is not such a policy.

The courts of appeals that have addressed this issue agree that the Supreme Court's recent decisions discussed above have moved toward reliance on state law, and away from the creation of federal common law, unless a conflict exists. In Atchison, T. & S.F. Ry. v. Brown & Bryant, 159 F.3d 358 (9th Cir.1997), the Court of Appeals for the Ninth Circuit considered whether the Supreme Court's pronouncements on this issue in O'Melveny and Atherton (Bestfoods had not yet been decided) were clear enough to cause it to abandon its own previous determination in Louisiana-Pacific Corp. v. Asarco, Inc., 909 F.2d 1260 (9th Cir.1990) (adopting Third Circuit's rationale in Smith Land) that the parameters of successor liability under CERCLA should be fashioned by federal common law in order to promote national uniformity. The Atchison court concluded that although the Atherton and O'Melveny opinions implicated FIRREA, and not CERCLA, the underlying analysis was nonetheless applicable and persuasive. 159 F.3d at 362. Thus, in concluding that the promotion of national uniformity does not justify application of federal common law to CERCLA, the Court effectively rejected its previous determination in Louisiana-Pacific along with that opinion's underlying rationale — our own opinion in Smith Land.

Initially, the Atchison Court correctly noted that "simply because a federal statute is involved does not always mean that federal courts should fashion a uniform federal rule." 159 F.3d at 362 (citation omitted). "Frequently, state rules of decision will furnish an appropriate and convenient measure of the governing federal law." Id. The subsequent discussion merits repeating in full:

In Louisiana-Pacific, we agreed with the Third Circuit that CERCLA's "`meager legislative history available indicates that Congress expected the courts to develop a federal common law to supplement the statute.'" 909 F.2d at 1263 (quoting Smith Land, 851 F.2d 86 at 91). This legislative history consists of a discussion in Congress that common law should govern the issue of joint and several liability under CERCLA. Louisiana-Pacific recognized that Congress did not address the particular issue of successor liability under CERCLA.

O'Melveny tells us that when dealing with a "comprehensive and detailed" federal statutory regulation, a court should instead presume that matters left unaddressed in such a scheme are subject to state law. "Congress acts ... against the background of the total corpus juris of the states...." Atherton, 117 S.Ct. at 670 (alteration in original). The formation of corporations and the dissolution and continuing liability of corporations are traditional areas of state law. As CERCLA lacks any clear directive that federal courts develop standards for successor liability, we turn to the Kimbell Foods test, as clarified by O'Melveny and Atherton.

* * *

Although Louisiana-Pacific refers to the "need for national uniformity" as a reason for developing federal rules for successor liability, Atherton notes that "to invoke the concept of `uniformity' ... is not to prove its need." 117 S. Ct. at 671; see also O'Melveny, 114 S.Ct. at 2055 (recognizing how generic and "lightly invoked" is the need for uniformity). Although often invoked in this context, there has been no real explanation of the need for uniformity in the particular area of successor liability — especially since state law will in many other instances determine whom the EPA may or may not look to for compensation. If state law varied widely on the issue of successor liability, perhaps the need for a uniform federal rule would be more apparent. This is not the case, however, as "the law in the fifty states on corporate dissolution and successor liability is largely uniform." Anspec Co. v. Johnson Controls, Inc., 922 F.2d 1240, 1249 (6th Cir.1991) (Kennedy, J., concurring) (holding that state law determines successor liability under CERCLA). The argued "need" for uniformity thus stems not from disarray among the various states, but from the alleged need for a more expansive view of successor liability than state law currently provides — in other words, the notion that state law on this issue is inadequate for CERCLA's purposes.

But O'Melveny and Atherton also speak to this argument. Before a court can recognize a federal rule of decision, there must be a "`significant conflict between some federal policy or interest and the use of state law.'" O'Melveny, 114 S.Ct. at 2055 (quoting Wallis, 384 U.S. 63 at 68, 86 S. Ct. 1301, 16 L. Ed. 2d 369). Indeed, such a conflict is a "precondition" to fashioning federal common law rules. Atherton, 117 S.Ct. at 670. The Court's recent cases clarify that to demonstrate such a conflict, more than speculation is required — there must be a "specific, concrete federal policy or interest that is compromised" by the application of state law. O'Melveny, 114 S.Ct. at 2055. We therefore doubt that the concern noted in Louisiana-Pacific is sufficient grounds for developing a federal rule of decision.

Atchison, 159 F.3d at 362-64 (certain internal citations and footnotes omitted).16 The Atchison Court concluded that it would not adopt the "substantial continuation" exception (which would have expanded federal common law liability). It then reasoned that because the same result would flow in the case before it under either state law or federal common law, it need not decide whether state or federal law governs successor liability under CERCLA. Id. at 364. Despite bypassing the question we now consider, it is abundantly clear that the Ninth Circuit, were its hand forced, would follow the recent directives of the Supreme Court and hold that state law should govern successor liability under CERCLA.

Even more recently, and with the benefit of the Bestfoods opinion, the Court of Appeals for the First Circuit, considering displacement of Connecticut state law to determine successor liability under CERCLA, did just that:

We have concluded that the majority rule is to apply state law "so long as it is not hostile to the federal interests animating CERCLA," and have applied Massachusetts contracts law to determine an issue of successor liability. John S. Boyd Co., Inc. v. Boston Gas Co., 992 F.2d 401, 406 (1st Cir.1993). Recent Supreme Court precedent confirms that Boyd's approach is correct. The Court applied state corporation law in a recent CERCLA case involving the potential liability of a parent corporation for its subsidiary and left little room for the creation of a federal rule of liability under the statute. See United States v. Bestfoods, 524 U.S. 51, 63, 118 S. Ct. 1876, 141 L. Ed. 2d 43 (1998) ("CERCLA is... like many another congressional enactment in giving no indication that the entire corpus of state corporation law is to be replaced simply because a plaintiff's cause of action is based upon a federal statute.") (internal quotation marks omitted). The Court's statements in Bestfoods and O'Melveny demonstrate that to justify the creation of a federal rule, "there must be a specific, concrete federal policy or interest that is compromised by the application of state law." Atchison, Topeka & Santa Fe Railway Co. v. Brown & Bryant, Inc., 159 F.3d 358, 363-64 (9th Cir.1998) (internal quotation marks omitted). We see no evidence that application of state law to the facts of this case would frustrate any federal objective. Connecticut's "mere continuation" test thus is the correct test for determining successor liability for the hazardous waste disposed.

United States v. Davis, 261 F.3d 1, 54 (1st Cir.2001).

As recognized by the Atchison and Davis courts, the Supreme Court has repeatedly emphasized that a specific and identifiable conflict must be present before we should invoke and apply a federal rule of decision. Here, no such conflict exists. Absent evidence that application of Pennsylvania state law, not the hypothetical application of the law of 49 other states, does frustrate CERCLA's purpose — holding liable parties responsible for the costs associated with the clean up of hazardous waste sites — and in the face of recent Supreme Court opinions discouraging the creation of a federal rule of decision, it is readily apparent that resort to any law other than Pennsylvania's is unnecessary and uncalled for.

I subscribe to and seek to reiterate a number of the majority's threshold observations, which it appears to note but then discard: namely, that the Supreme Court has "cautioned against the unwarranted displacement of state law" (Maj. Op.) (citing O'Melveny, 512 U.S. at 87, 114 S. Ct. 2048); additionally, that "[i]ncorporation of state law is particularly favored in the area of corporate law, because business decisions proceed in reliance on the applicable state standards" (Id.) (citing Kamen, 111 S.Ct. at 1722); and, finally, that absent some significant conflict arises between a federal policy interest and the use of state law, "state corporation law generally should be integrated into the federal statutory regime." (Id.) (citing United States v. Kimbell Foods, Inc., 440 U.S. 715, 99 S. Ct. 1448, 59 L. Ed. 2d 711 (1979)) (other citations omitted). But, it is not clear to me why, in the face of these guiding principles, the majority then frames the issue before us simply as "whether CERCLA requires a uniform federal standard of corporate successor liability." (Maj. Op.)

The majority's determination that application of federal common law is warranted here hinges on our previous terse treatment of the issue in Smith Land & Improv. Corp. v. Celotex Corp., 851 F.2d 86 (3d Cir.1988) and Lansford-Coaldale Joint Water Auth. v. Tonolli Corp., 4 F.3d 1209 (3d Cir.1993), cases in which the Court advanced only one animating rationale for adopting the "general doctrine of successor liability in operation in most states," 851 F.2d at 92 — the need for a uniform and predictable body of law. We did so in a few conclusory sentences, without any meaningful discussion. Intervening Supreme Court precedent makes clear, however, that this rationale is no longer, if it ever was, paramount when evaluating whether we are confronted with "one of those extraordinary cases in which the judicial creation of a federal rule of decision is warranted." O'Melveny & Myers v. FDIC, 512 U.S. 79, 89, 114 S. Ct. 2048, 129 L. Ed. 2d 67 (1994). To the extent Smith Land and Lansford-Coaldale command us to ignore in our analysis longstanding, ingrained principles of state corporate law in favor of "that most generic (and lightly invoked) of alleged federal interests, the interest in uniformity," id. at 88, 114 S. Ct. 2048, those decisions should be reevaluated. George Harms Constr. Co. v. Chao, 371 F.3d 156, 161 (3d Cir.2004) ("We recognize that we may reevaluate a precedent in light of intervening authority even without en banc consideration."); United States v. Adams, 252 F.3d 276, 286 (3d Cir.2001) ("Although a panel of this court is bound by, and lacks authority to overrule, a published decision of a prior panel, a panel may reevaluate a precedent in light of intervening authority.") (internal quotations omitted). We must reevaluate the exalted position that we previously afforded "uniformity" in light of the Supreme Court's direction that we are to employ a different mode of analysis.17

The majority asserts that resort to federal common law is necessary because state laws concerning successor liability are not uniform and thus, without fashioning a federal rule of decision, predictability will be lacking. To say that the need for uniformity is the articulated federal policy supplying the rationale for creating federal common law is to put the analytic rabbit in the hat, so to speak. If uniform application is indeed the goal, resort would never be had to state law assuming some variation as among the different laws. Uniformity cannot be, and has never been said to be, the single animating principle. While it is a laudable goal, it is not one that has served as the basis on which the Supreme Court, or any other court of appeals to have addressed the issue, has rejected the application of state law. Rather, as discussed above and made clear in O'Melveny and Atherton, those courts that have considered rejecting the application of a particular state law in favor of a federal scheme have done so only when the state law in question clearly conflicted with an important federal policy to be advanced. See, e.g., Kamen, 500 U.S. at 98, 111 S. Ct. 1711; Boyle, 487 U.S. at 504, 108 S. Ct. 2510; Texas Industries, Inc., 451 U.S. at 641, 101 S. Ct. 2061; Wallis, 384 U.S. at 68, 86 S. Ct. 1301; Sabbatino, 376 U.S. at 425, 84 S. Ct. 923; Wheeldin, 373 U.S. at 651, 83 S. Ct. 1441; Lyons, 360 U.S. at 596, 79 S. Ct. 1331; Standard Oil Co. of Cal., 332 U.S. at 305, 67 S. Ct. 1604. See also Redwing Carriers, Inc., v. Saraland Apartments, 94 F.3d 1489, 1501-02 (11th Cir.1996) (holding that state law should be adopted as the federal standard for determining whether a limited partner may be held accountable for the CERCLA liability of the partnership). These cases also make clear that it is the second factor of the Kimbell Foods test18 which should receive paramount consideration. The Supreme Court in O'Melveny and Atherton cite to the Kimbell Foods test in direct support of the precept that "when courts decide to fashion rules of federal common law, `the guiding principle is that a significant conflict between some federal policy or interest and the use of state law ... must first be specifically shown.' Indeed, such a `conflict' is normally a `precondition.'" Atherton, 519 U.S. at 218, 117 S. Ct. 666 (quoting O'Melveny, 512 U.S. at 87, 114 S. Ct. 2048, and citing Kimbell Foods, 440 U.S. at 728, 99 S. Ct. 1448). The Court in Atherton cites to Kimbell Foods an additional time, where it explains, "To invoke the concept of `uniformity,' [] is not to prove its need." 519 U.S. at 220, 117 S. Ct. 666 (citing Kimbell Foods, 440 U.S. at 730, 99 S. Ct. 1448 (rejecting "generalized pleas for uniformity")). Certainly, neither opinion relies, as the majority seems to do, on Kimbell Foods' other espoused consideration — whether the federal program requires uniformity, or come close to elevating this factor to the point of deeming it a "precondition," as has the Court with respect to the presence of a significant conflict.19

Clearly, the required conflict does not exist here; application of Pennsylvania law produces the desired result. Therefore, we need not abandon Pennsylvania law, nor should we label the rule applied today by the majority "federal." Accordingly, I respectfully dissent from the reasoning contained in the majority's opinion but concur in the resulting affirmance of the District Court's order.
