Chemical Waste Management, Inc. v. Hunt , 112 S. Ct. 2009 ( 1992 )

Justice White

delivered the opinion of the Court.

Alabama imposes a hazardous waste disposal fee on hazardous wastes generated outside the State and disposed of at a commercial facility in Alabama. The fee does not apply to such waste having a source in Alabama. The Alabama Supreme Court held that this differential treatment does not violate the Commerce Clause. We reverse.

I

Petitioner, Chemical Waste Management, Inc., a Delaware corporation with its principal place of business in Oak Brook, Illinois, owns and operates one of the Nation’s oldest commercial hazardous waste land disposal facilities, located in Emelle, Alabama. Opened in 1977 and acquired by petitioner in 1978, the Emelle facility is a hazardous waste treatment, storage, and disposal facility operating pursuant to permits issued by the Environmental Protection Agency (EPA) under the Resource Conservation and Recovery Act of 1976 (RCRA), 90 Stat. 2795, as amended, 42 U. S. C. §6901 et seq., and the Toxic Substances Control Act, 90 Stat. 2003, as amended, 15 U. S. C. § 2601 et seq. (1988 ed. and Supp. II), and by the State of Alabama under Ala. Code § 22 — 30—12(i) (1990). Alabama is 1 of only 16 States that have commercial hazardous waste landfills, and the Emelle facility is the largest of the 21 landfills of this kind located in these 16 States. Brief for National Governors’ Assn, et al. as Amici Curiae 3, citing E. Smith, El Digest 26-27 (Mar. 1992).

The parties do not dispute that the wastes and substances being landfilled at the Emelle facility “include substances that are inherently dangerous to human health and safety and to the environment. Such waste consists of ignitable, corrosive, toxic and reactive wastes which contain poisonous and cancer causing chemicals and which can cause birth defects, genetic damage, blindness, crippling and death.”¹ 584 So. 2d 1367, 1373 (Ala. 1991). Increasing amounts of out-of-state hazardous wastes are shipped to the Emelle facility for permanent storage each year. From 1985 through 1989, the tonnage of hazardous waste received per year has more than doubled, increasing from 341,000 tons in 1985 to 788,000 tons by 1989. Of this, up to 90% of the tonnage permanently buried each year is shipped in from other States.

Against this backdrop Alabama enacted Act No. 90-326 (Act). Ala. Code §§22-30B-1 to 22-30B-18 (1990 and Supp. 1991). Among other provisions, the Act includes a “cap” that generally limits the amount of hazardous wastes or substances² that may be disposed of in any 1-year period, and the amount of hazardous waste disposed of during the first year under the Act’s new fees becomes the permanent ceiling in subsequent years. Ala. Code § 22-30B-2.3 (1990). The cap applies to commercial facilities that dispose of over 100,000 tons of hazardous wastes or substances per year, but only the Emelle facility, as the only commercial facility operating within Alabama, meets this description. The Act also imposes a “base fee” of $25.60 per ton on all hazardous wastes and substances disposed of at commercial facilities, to be paid by the operator of the facility. Ala. Code §22-30B-2(a) (Supp. 1991). Finally, the Act imposes the “additional fee” at issue here, which states in full:

“For waste and substances which are generated outside of Alabama and disposed of at a commercial site for the disposal of hazardous waste or hazardous substances in Alabama, an additional fee shall be levied at the rate of $72.00 per ton.” § 22-30B-2(b).

Petitioner filed suit in state court requesting declaratory relief against respondents and seeking to enjoin enforcement of the Act. In addition to state-law claims, petitioner contended that the Act violated the Commerce, Due Process, and Equal Protection Clauses of the United States Constitution, and was pre-empted by various federal statutes. The trial court declared the base fee and the cap provisions of the Act to be valid and constitutional; but, finding the only basis for the additional fee to be the origin of the waste, the trial court declared it to be in violation of the Commerce Clause. App. to Pet. for Cert. 83a-88a. Both sides appealed. The Alabama Supreme Court affirmed the rulings concerning the base fee and cap provisions but reversed the decision regarding the additional fee. The court held that the fee at issue advanced legitimate local purposes that could not be adequately served by reasonable nondiscriminatory alternatives and was therefore valid under the Commerce Clause. 584 So. 2d, at 1390.

Chemical Waste Management, Inc., petitioned for writ of certiorari, challenging all aspects of the Act. Because of the importance of the federal question and the likelihood that it had been decided in a way conflicting with applicable decisions of this Court, this Court’s Rule 10.1(c), we granted certiorari limited to petitioner’s Commerce Clause challenge to the additional fee. 502 U. S. 1070 (1992). We now reverse.

II

No State may attempt to isolate itself from a problem common to the several States by raising barriers to the free flow of interstate trade.³ Today, in Fort Gratiot Sanitary Landfill, Inc. v. Michigan Dept. of Natural Resources, post, p. 358, we have also considered a Commerce Clause challenge to a Michigan law prohibiting private landfill operators from accepting solid waste originating outside the county in which their facilities operate. In striking down that law, we adhered to our decision in Philadelphia v. New Jersey, 437 U. S. 617 (1978), where we found New Jersey’s prohibition of solid waste from outside that State to amount to economic protectionism barred by the Commerce Clause:

“‘[T]he evil of protectionism can reside in legislative means as well as legislative ends. Thus, it does not matter whether the ultimate aim of ch. 363 is to réduce the waste disposal costs of New Jersey residents or to save remaining open lands from pollution, for we assume New Jersey has every right to protect its residents’ pocketbooks as well as their environment. And it may be assumed as well that New Jersey may pursue those ends by slowing the flow of all waste into the State’s remaining landfills, even though interstate commerce may incidentally be affected. But whatever New Jersey’s ultimate purpose, it may not be accompanied by discriminating against articles of commerce coming from outside the State unless there is some reason, apart from their origin, to treat them differently. Both on its face and in its plain effect, ch. 363 violates this principle of nondiscrimination.

“ ‘The Court has consistently found parochial legislation of this kind to be constitutionally invalid, whether. the ultimate aim of the legislation was to assure a steady supply of milk by erecting barriers to allegedly ruinous outside competition, Baldwin v. G. A. F. Seelig, Inc., 294 U. S. [511,] 522-524 [(1935)]; or to create jobs by keeping industry within the State, Foster-Fountain Packing Co. v. Haydel, 278 U. S. 1, 10 [(1928)]; Johnson v. Haydel, 278 U. S. 16 [(1928)]; Toomer v. Witsell, 334 U. S. [385,] 403-404 [(1948)]; or to preserve the State’s financial resources from depletion by fencing out indigent immigrants, Edwards v. California, 314 U. S. 160, 173-174 [(1941)].’ ” Fort Gratiot Sanitary Landfill, post, at 360 (quoting Philadelphia v. New Jersey, supra, at 626-627).

To this list may be added cases striking down a tax discriminating against interstate commerce, even where such tax was designed to encourage the use of ethanol and thereby reduce harmful exhaust emissions, New Energy Co. of Ind. v. Limbach, 486 U. S. 269, 279 (1988), or to support inspection of foreign cement to ensure structural integrity, Hale v. Bimco Trading, Inc., 306 U. S. 375, 379-380 (1939). For in all of these cases, “a presumably legitimate goal was sought to be achieved by the illegitimate means of isolating the State from the national economy.” Philadelphia v. New Jersey, supra, at 627.

The Act’s additional fee facially discriminates against hazardous waste generated in States other than Alabama, and the Act overall has plainly discouraged the full operation of petitioner’s Emelle facility.⁴ Such burdensome taxes imposed on interstate commerce alone are generally forbidden: “[A] State may not tax a transaction or incident more heavily when it crosses state lines than when it occurs entirely within the State.” Armco Inc. v. Hardesty, 467 U. S. 638, 642 (1984); see also Walling v. Michigan, 116 U. S. 446, 455 (1886); Guy v. Baltimore, 100 U. S. 434, 439 (1880). Once a state tax is found to discriminate against out-of-state commerce, it is typically struck down without further inquiry. See, e. g., Westinghouse Electric Corp. v. Tully, 466 U. S. 388, 406-407 (1984); Maryland v. Louisiana, 451 U. S. 725, 759-760 (1981); Boston Stock Exchange v. State Tax Comm’n, 429 U. S. 318, 336-337 (1977).

The State, however, argues that the additional fee imposed on out-of-state hazardous waste serves legitimate local purposes related to its citizens’ health and safety. Because the additional fee discriminates both on its face and in practical effect, the burden falls on the State “to justify it both in terms of the local benefits flowing from the statute and the unavailability of nondiscriminatory alternatives adequate to preserve the local interests at stake.” Hunt v. Washington State Apple Advertising Comm’n, 432 U. S. 333, 353 (1977); see also Fort Gratiot Sanitary Landfill, post, at 359; New Energy Co., supra, at 278-279. “At a minimum such facial discrimination invokes the strictest scrutiny of any purported legitimate local purpose and of the absence of nondiscriminatory alternatives.” Hughes v. Oklahoma, 441 U. S. 322, 337 (1979).⁵

The State’s argument here does not significantly differ from the Alabama Supreme Court’s conclusions on the legitimate local purposes of the additional fee imposed, which were:

“The Additional Fee serves these legitimate local purposes that cannot be adequately served by reasonable nondiscriminatory alternatives: (1) protection of the health and safety of the citizens of Alabama from toxic substances; (2) conservation of the environment and the state’s natural resources; (3) provision for compensatory revenue for the costs and burdens that out-of-state waste generators impose by dumping their hazardous waste in Alabama; (4) reduction of the overall flow of wastes traveling on the state’s highways, which flow creates a great risk to the health and safety of the state’s citizens.” 584 So. 2d, at 1389.

These may all be legitimate local interests, and petitioner has not attacked them. But only rhetoric, and not explanation, emerges as to why Alabama targets only interstate hazardous waste to meet these goals. As found by the trial court, “[although the Legislature imposed an additional fee of $72.00 per ton on waste generated outside Alabama, there is absolutely no evidence before this Court that waste generated outside Alabama is more dangerous than waste generated in Alabama. The Court finds under the facts of this case that the only basis for the additional fee is the origin of the waste.” App. to Pet. for Cert. 83a-84a. In the face of such findings, invalidity under the Commerce Clause necessarily follows, for “whatever [Alabama’s] ultimate purpose, it may not be accomplished by discriminating against articles of commerce coming from outside the State unless there is some reason, apart from their origin, to treat them differently.” Philadelphia v. New Jersey, 437 U. S., at 626-627; see New Energy Co., 486 U. S., at 279-280. The burden is on the State to show that “the discrimination is demonstrably justified by a valid factor unrelated to economic protectionism,”⁶ Wyoming v. Oklahoma, 502 U. S. 437, 454 (1992) (emphasis added), and it has not carried this burden. Cf. Fort Gratiot Sanitary Landfill, post, at 361.

Ultimately, the State’s concern focuses on the volume of the waste entering the Emelle facility.⁷ Less discriminatory alternatives, however, are available to alleviate this concern, not the least of which are a generally applicable per-ton additional fee on all hazardous waste disposed of within Alabama, cf. Commonwealth Edison Co. v. Montana, 453 U. S. 609, 619 (1981), or a per-mile tax on all vehicles transporting hazardous waste across Alabama roads, cf. American Trucking Assns., Inc. v. Scheiner, 483 U. S. 266, 286 (1987), or an evenhanded cap on the total tonnage landfilled at Emelle, see Philadelphia v. New Jersey, supra, at 626, which would curtail volume from all sources.⁸ To the extent Alabama’s concern touches environmental conservation and the health and safety of its citizens, such concern does not vary with the point of origin of the waste, and it remains within the State’s power to monitor and regulate more closely the transportation and disposal of all hazardous waste within its borders. Even with the possible future financial and environmental risks to be borne by Alabama, such risks likewise do not vary with the waste’s State of origin in a way allowing foreign, but not local, waste to be burdened.⁹ In sum, we find the additional fee to be “an obvious effort to saddle those outside the State” with most of the burden of slowing the flow of waste into the Emelle facility. Philadelphia v. New Jersey, 437 U. S., at 629. “That legislative effort is clearly impermissible under the Commerce Clause of the Constitution.” Ibid.

Our decisions regarding quarantine laws do not counsel a different conclusion.¹⁰ The Act’s additional fee may not legitimately be deemed a quarantine law because Alabama permits both the generation and landfilling of hazardous waste within its borders and the importation of still more hazardous waste subject to payment of the additional fee. In any event, while it is true that certain quarantine laws have not been considered forbidden protectionist measures, even though directed against out-of-state commerce, those laws “did not discriminate against interstate commerce as such, but simply prevented traffic in noxious articles, whatever their origin.” Philadelphia v. New Jersey, supra, at 629.¹¹ As the Court stated in Guy v. Baltimore, 100 U. S., at 443:

“In the exercise of its police powers, a State may exclude from its territory, or prohibit the sale therein of any articles which, in its judgment, fairly exercised, are prejudicial to the health or which would endanger the lives or property of its people. But if the State, under the guise of exerting its police powers, should make such exclusion or prohibition applicable solely to articles, of that kind, that may be produced or manufactured in other States, the courts would find no difficulty in holding such legislation to be in conflict with the Constitution of the United States.”

See also Reid v. Colorado, 187 U. S. 137, 151 (1902); Railroad Co. v. Husen, 95 U. S. 465, 472 (1878).

The law struck down in Philadelphia v. New Jersey left local waste untouched, although no basis existed by which to distinguish interstate waste. But “[i]f one is inherently harmful, so is the other. Yet New Jersey has banned the former while leaving its landfill sites open to the latter.” 437 U. S., at 629. Here, the additional fee applies only to interstate hazardous waste, but at all points from its entrance into Alabama until it is landfilled at the Emelle facility, every concern related to quarantine applies perforce to local hazardous waste, which pays no additional fee. For this reason, the additional fee does not survive the appropriate scrutiny applicable to discriminations against interstate commerce.

Maine v. Taylor, 477 U. S. 131 (1986), provides no additional justification. Maine there demonstrated that the out-of-state baitfish were subject to parasites foreign to in-state baitfish. This difference posed a threat to the State’s natural resources, and absent a less discriminatory means of protecting the environment — and none was available — the importation of baitfish could properly be banned. Id., at 140. To the contrary, the record establishes that the hazardous waste at issue in this case is the same regardless of its point of origin. As noted in Fort Gratiot Sanitary Landfill, “our conclusion would be different if the imported waste raised health or other concerns not presented by [Alabama] waste.” Post, at 367. Because no unique threat is posed, and because adequate means other than overt discrimination meet Alabama’s concerns, Maine v. Taylor provides the State no respite.

Ill

The decision of the Alabama Supreme Court is reversed, and the cause is remanded for proceedings not inconsistent with this opinion, including consideration of the appropriate relief to petitioner. See McKesson Corp. v. Division of Alcoholic Beverages and Tobacco, Fla. Dept. of Business Regulations, 496 U. S. 18, 31 (1990); Tyler Pipe Industries, Inc. v. Washington State Dept. of Revenue, 483 U. S. 232, 251-253 (1987).

So ordered.

1 As used in RCRA, 42 U. S. C. § 6903(5), the term “hazardous waste” means:

“a solid waste, or combination of solid wastes, which because of its quantity, concentration, or physical, chemical, or infectious characteristics may—

“(A) cause, or significantly contribute to an increase in mortality or an increase in serious irreversible, or incapacitating reversible, illness; or

“(B) pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or disposed of, or otherwise managed.”

RCRA directs the EPA to establish a comprehensive “cradle to grave” system regulating the generation, transport, storage, treatment, and disposal of hazardous wastes, §§6921-6939b, which includes identification and listing of hazardous wastes, § 6921. At present, there are more than 600 such listed wastes. See 40 CFR pt. 261, subpt. D (1991).

2 “Hazardous substance(s)” and “hazardous waste(s)” are defined terms in the Act, §§ 22-30B-1(3) and 22-30B-1(4), but these definitions largely parallel the meanings given under federal law.

3 The Alabama Supreme Court assumed that the disposal of hazardous waste constituted an article of commerce, and the State does not explicitly argue here to the contrary. In Fort Gratiot Sanitary Landfill, Inc. v. Michigan Dept. of Natural Resources, post, at 359, we have reaffirmed the idea that “[s]olid waste, even if it has no value, is an article of commerce.” As stated in Philadelphia v. New Jersey, 437 U. S. 617, 622-623 (1978): “All objects of interstate trade merit Commerce Clause protection; none is excluded by definition at the outset. . . . Just as Congress has power to regulate the interstate movement of these wastes, States are not free from constitutional scrutiny when they restrict that movement.” The definition of “hazardous waste” makes clear that it is simply a grade of solid waste, albeit one of particularly noxious and dangerous propensities, see n. 1, supra, but whether the business arrangements between out-of-state generators of hazardous waste and the Alabama operator of a hazardous waste landfill are viewed as “sales” of hazardous waste or “pirn-chases” of transportation and disposal services, “the commercial transactions unquestionably have an interstate character. The Commerce Clause thus imposes some constraints on [Alabama’s] ability to regulate these transactions.” Fort Gratiot Sanitary Landfill, post, at 359. See National Solid Wastes Management Assn. v. Alabama Dept. of Environmental Mgmt., 910 F. 2d 713, 718-719 (CA11 1990), modified, 924 F. 2d 1001, cert. denied, 501 U. S. 1206 (1991).

4 The Act went into effect July 15, 1990. The volume of hazardous waste buried at the Emelle facility fell dramatically from 791,000 tons in 1989 to 290,000 tons in 1991.

5 To some extent the State attempts to avail itself of the more flexible approach outlined in, e. g., Brown-Forman Distillers Corp. v. New York State Liquor Authority, 476 U. S. 573, 579 (1986), and Pike v. Bruce Church, Inc., 397 U. S. 137, 142 (1970), but this lesser scrutiny is only available “where other legislative objectives are credibly advanced and there is no patent discrimination against interstate trade.” Philadelphia v. New Jersey, 437 U. S., at 624 (emphasis added). We find no room here to say that the Act presents “effects upon interstate commerce that are only incidental,” ibid., for the Act’s additionabfee on its face targets only out-of-state hazardous waste. While no “clear line” separates close cases on which scrutiny should apply, “this is not a close case.” Wyoming v. Oklahoma, 502 U. S. 437, 455, n. 12 (1992).

6 The Alabama Supreme Court found no “economic protectionism” here, and thus purported to distinguish Philadelphia v. New Jersey, based on its conclusions that the legislature was motivated by public health and environmental concerns. 584 So. 2d 1367, 1388-1389 (1991). This narrow focus on the intended consequence of the additional fee does not conform to our precedents, for “[a] finding that state legislation constitutes ‘economic protectionism’ may be made on the basis of either discriminatory purpose, see Hunt v. Washington Apple Advertising Comm’n, 432 U. S. 333, 352-353 (1977), or discriminatory effect, see Philadelphia v. New Jersey, supra.” Bacchus Imports, Ltd. v. Dias, 468 U. S. 263, 270 (1984). The “virtually per se rule of invalidity,” Philadelphia v. New Jersey, supra, at 624, applies “not only' to laws motivated solely by a desire to protect local industries from out-of-state competition, but also to laws that respond to legitimate local concerns by discriminating arbitrarily against interstate trade.” Maine v. Taylor, 477 U. S. 131, 148, n. 19 (1986).

7 “The risk created by hazardous waste and other similarly dangerous waste materials is proportional to the volume of such waste materials present, and may be controlled by controlling that volume.” Brief for Respondents 38 (citation omitted; emphasis in original).

8 The State asserts: “An equal fee, at any level, would necessarily fail to serve the State’s purpose. An equal fee high enough to provide any significant deterrent to the importation of hazardous waste for landfilling in the State would amount to an attempt by the State to avoid its responsibility to deal with its own problems, by tending to cause in-state waste to be exported for disposal. An equal fee not so high as to amount to an attempt to force Alabama’s own problems to be borne by citizens of other states would fail to provide any significant reduction in the enormous volumes of imported hazardous waste being dumped in the State. At the point where an equal fee would become effective to serve the State’s purpose in protecting public health and the environment from uncontrolled volumes of imported waste, that equal fee would also become an avoidance of the State’s responsibility to deal with its own waste problems.” Id., at 46. These assertions are without record support and in any event do not suffice to validate plain discrimination against interstate commerce. See New Energy Co. of Ind. v. Limbach, 486 U. S. 269, 280 (1988); Hale v. Bimco Trading, Inc., 306 U. S. 375, 380 (1939): “That no Florida cement needs any inspection while all foreign cement requires inspection at a cost of fifteen cents per hundredweight is too violent an assumption to justify the discrimination here disclosed.” The additional fee is certainly not a “ ‘last ditch’ attempt” to meet Alabama’s expressed purposes “after nondis-eriminatory alternatives have proved unfeasible. It is rather a choice of the most discriminatory [tax] even though nondiscriminatory alternatives would seem likely to fulfill the State’s purported legitimate local purpose more effectively.” Hughes v. Oklahoma, 441 U. S. 322, 338 (1979).

9 The State presents no argument here, as it did below, that the additional fee makes out-of-state generators pay their “fair share” of the costs of Alabama waste disposal facilities, or that the additional fee is justified as a “compensatory tax.” The trial court rejected these arguments, App. to Pet. for Cert. 88a, n. 6., finding the former foreclosed by American Trucking Assns., Inc. v. Scheiner, 483 U. S. 266, 287-289 (1987), and the latter to be factually unsupported by a requisite “substantially equivalent” tax imposed solely on in-state waste, as required by, e. g., Tyler Pipe Industries, Inc. v. Washington State Dept. of Revenue, 483 U. S. 232, 242-244 (1987). Various amici assert that the discrimination patent in the Act’s additional fee is consistent with congressional authorization. We pretermit this issue, for it was not the basis for the decision below and has not been briefed or argued by the parties here.

10 The State collects and refers to the following decisions, inter alia, as “quarantine cases”: Clason v. Indiana, 306 U. S. 439 (1939); Mintz v. Baldwin, 289 U. S. 346 (1933); Oregon-Washington Railroad & Navigation Co. v. Washington, 270 U. S. 87 (1926); Sligh v. Kirkwood, 237 U. S. 52 (1915); Asbell v. Kansas, 209 U. S. 251 (1908); Reid v. Colorado, 187 U. S. 137 (1902); Compagnie Francaise de Navigation a Vapeur v. Louisiana Bd. of Health, 186 U. S. 380 (1902); Smith v. St. Louis & Southwestern R. Co., 181 U. S. 248 (1901); Rasmussen v. Idaho, 181 U. S. 198 (1901); Missouri, K. & T. R. Co. v. Haber, 169 U. S. 613 (1898); Bowman v. Chicago & Northwestern R. Co., 125 U. S. 466 (1888); Railroad Co. v. Husen, 95 U. S. 465 (1878).

11 “The hostility is to the thing itself, not to merely interstate shipments of the thing; and an undiscriminating hostility is at least nondiscriminatory. But that is not the case here. The State of Illinois is quite willing to allow the storage and even the shipment for storage of spent nuclear fuel in Illinois, provided only that its origin is intrastate.” Illinois v. General Elec. Co., 683 F. 2d 206, 214 (CA7 1982), cert. denied, 461 U. S. 913 (1983); cf Oregon-Washington Co. v. Washington, swpra, at 96: Inspection followed by quarantine of hay from fields infested with weevils is “a real quarantine law, and not a mere inhibition against importation of alfalfa from a large part of the country without regard to the condition which might make its importation dangerous.”
