GRABER, Justice.
At issue in this case is the validity of regulations imposing a per-ton surcharge on the disposal in Oregon of solid waste generated outside the state. ORS 459.297(1) provides:
"Beginning on January 1, 1991, every person who disposes of solid waste generated out-of-state in a disposal site or regional disposal site shall pay a surcharge as established by the Environmental Quality Commission under ORS 459.298. The surcharge shall be in addition to any other fee charged for disposal of solid waste at the site."
ORS 459.298 provides:
"Subject to approval by the Joint Committee on Ways and Means during the legislative sessions or the Emergency Board during the interim between sessions, the Environmental Quality Commission shall establish by rule the amount of the surcharge to be collected under ORS 459.297. The amount of the surcharge shall be based on the costs to the State of Oregon and its political subdivisions of disposing of solid waste generated out-of-state which are not otherwise paid for under the provisions of [statutes relating to solid waste disposal, domestic solid waste disposal, and household hazardous waste disposal]. These costs may include but need not be limited to costs incurred for:
"(1) Solid waste management;
"(2) Issuing new and renewal permits for solid waste disposal sites;
"(3) Environmental monitoring;
"(4) Ground water monitoring; and
"(5) Site closure and post-closure activities."
*503 As authorized by ORS 459.297 and 459.298, the Environmental Quality Commission (EQC) promulgated rules pertaining to the disposal of solid waste. OAR 340-61-115(1) provides in part:
"Beginning July 1, 1984, each person required to have a Solid Waste Disposal Permit shall be subject to a three-part fee consisting of a filing fee, an application processing fee and an annual compliance determination fee as listed in OAR 340-61-120. In addition, each disposal site receiving domestic solid waste shall be subject to an annual recycling program implementation fee as listed in OAR 340-61-120, and a per-ton fee on domestic solid waste * * *. In addition, each disposal site or regional disposal site receiving waste generated out-of-state shall pay a surcharge * * *."
OAR 340-61-120(6) provides:
"Surcharge on disposal of waste generated out-of-state. Each solid waste disposal site or regional solid waste disposal site that receives solid waste generated out-of-state shall submit to the Department of Environmental Quality a per-ton surcharge of $2.25. This surcharge shall apply to each ton of out-of-state waste received at the disposal site[.]"
Petitioners Oregon Waste Systems, Inc., Columbia Resource Company, L.P., and Gilliam County, Oregon,[1] sought judicial review of OAR 340-61-115(1) and 340-61-120(6) in the Court of Appeals pursuant to ORS 183.400.[2] Petitioners argue that, because ORS 459.298 requires approval of the amount of the surcharge by the Joint Ways and Means Committee or by the Emergency Board and because those approval provisions are not severable from the remainder of the statute, ORS 459.298 violates Article I, section 21;[3] Article III, sections 1[4] and *504 3;[5] Article IV, section 25;[6] and Article V, section 15b,[7] of the Oregon Constitution. As a result, they argue, the implementing regulations also are invalid. In the alternative, petitioners argue that, even if ORS 459.298, OAR 340-61-115(1), and OAR 340-61-120(6) are valid under the Oregon Constitution, they are invalid because they impermissibly discriminate against interstate commerce in violation of the Commerce Clause, Article I, section 8, clause 3,[8] of the Constitution of the United States.
Respondent Department of Environmental Quality (DEQ), the state agency for which EQC is the policy making body, concedes that, "to the extent [that ORS 459.-298] subjects DEQ's surcharge determination to Emergency Board approval," that statute is unconstitutional under Article III, sections 1 and 2,[9] and Article IV, section 25, of the Oregon Constitution. DEQ argues, however, that that portion of the statute is severable and that the remainder of the statute and its accompanying regulations are valid under the Oregon Constitution and under the Commerce Clause, Article I, section 8, clause 3, of the Constitution of the United States.
The Court of Appeals accepted DEQ's concession as to the unconstitutionality of the portion of ORS 459.298 relating to approval of the surcharge by the Emergency Board, concluding that that portion violates Article III, section 3, of the Oregon Constitution. Gilliam County v. Dept. of Environmental Quality, 114 Or.App. 369, 375-76, 837 P.2d 965 (1992). The Court of Appeals concluded that the portion of ORS 459.298 relating to approval of the surcharge by the Joint Committee on Ways and Means also is unconstitutional, because it violates Article IV, section 25, of the Oregon Constitution. Id. at 379-80, 837 P.2d 965. The court held, however, that those portions of the statute are severable and that "the language that remains after both approval provisions are deleted is still a workable statute that contains clear standards for EQC to follow." Id. at 378, 382-383, 837 P.2d 965. Next, the Court of Appeals held that OAR 340-61-115(1) and 340-61-120(6) do not violate the Commerce Clause, because the surcharge imposed on out-of-state waste is a permissible "compensatory fee for specific costs incurred by the state" in the disposal of that waste and because, under the scope of review granted to the court by ORS 183.400, the court could not say that the amount of that fee either impermissibly exceeds those state costs or is insufficiently related to the services provided by the state in relation to disposal of out-of-state waste. Id. at 383-88, 837 P.2d 965. We affirm the decision of the Court of Appeals.
*505 We begin by considering petitioners' state law claims. See State v. Kennedy, 295 Or. 260, 262, 666 P.2d 1316 (1983) (court decides questions of state law before reaching federal constitutional issues). Further, "[t]his court follows the principle that constitutional issues should not be decided when there is an adequate statutory basis for a decision." Planned Parenthood Assn. v. Dept. of Human Resources, 297 Or. 562, 564, 687 P.2d 785 (1984).
In a challenge to a regulation under ORS 183.400(4), this court first decides whether the regulation was promulgated according to applicable rulemaking procedures. ORS 183.400(4)(c). We then decide whether the promulgation of the regulation was within the jurisdictional authority of the promulgating agency and whether the substance of the regulation neither departed from the legal standard expressed or implied in the enabling statute, nor contravened any other applicable statute. ORS 183.400(4)(b). Only after determining that the regulation meets those requirements do we consider the question whether the regulation violates any provision of the Oregon or United States Constitution. ORS 183.-400(4)(a). See Planned Parenthood Assn. v. Dept. Of Human Resources, supra, 297 Or. at 565, 687 P.2d 785 (setting forth that three-part analysis).
First, petitioners make no contention that the challenged regulations were "adopted without compliance with applicable rulemaking procedures," namely, the rulemaking procedures established by ORS 459.298. ORS 183.400(4)(c).
Next, as petitioners concede, EQC had jurisdictional authority to promulgate OAR 340-61-115(1) and 340-61-120(6). Petitioners do not contend that those regulations depart from the legal standards expressed or implied in the authorizing statute, ORS 459.298.
Petitioners contend, however, that, because the regulations include the cost of out-of-state waste reduction certification as a component of the surcharge, they contravene ORS 459.305. We disagree. ORS 459.305(1) provides that disposal sites may not accept waste generated outside the county in which the site is located unless DEQ certifies that the latter area has implemented a recycling program. ORS 459.305(4) permits DEQ to establish, according to the rulemaking procedures provided in ORS 468.065, a certification fee in relation to that requirement. Nothing in ORS 459.305 or 468.065 prohibits DEQ from including the cost to the state of certifying out-of-state waste reduction programs as a component of the surcharge authorized under ORS 459.298.
For the above reasons, we conclude that OAR 340-61-115(1) and 340-61-120(6) are not invalid under ORS 183.400(4)(b) in any of the particulars urged by petitioners.
We thus reach the question whether OAR 340-61-115(1) and 340-61-120(6) violate any provisions of the Oregon or United States Constitution, ORS 183.400(4)(a), and turn to petitioners' state constitutional claim. We begin by asking whether, as petitioners allege, the statute in accordance with which those regulations were promulgated is itself impermissible in relation to any provision of the Oregon Constitution. See ORS 183.400(3)(b) (judicial review of rule includes examination of statutory provisions authorizing the rule).
As did the Court of Appeals, we conclude that ORS 459.298 is unconstitutional in two respects. First, as respondent concedes, ORS 459.298 is constitutionally impermissible insofar as it requires approval of EQC's rules by the Emergency Board. Second, the statute is constitutionally impermissible insofar as it requires approval of EQC's rules by the Joint Committee on Ways and Means. As written, ORS 459.-298 requires either the Emergency Board (in the interim between legislative sessions) or the Joint Committee on Ways and Means (during sessions of the Legislative Assembly) to approve the rules before they can become legally effective. That requirement gives the Emergency Board or the Joint Committee on Ways and Means the right to veto the rules. But, a veto is a legislative act, and a legislative act by less than a majority vote of each chamber is unconstitutional. See Or. Const. Art. III, *506 § 3, set out in part at note 5, supra (authorizing establishment of Emergency Board with certain enumerated powers, not including the power to approve or disapprove the rules at issue in this case); Or. Const., Art. IV, § 25, set out in part at note 6, supra (legislation must be passed by a majority of all members of each house of the Legislative Assembly and signed by the presiding officers of the respective houses); Or. Const., Art. V, § 15b, set out in part at note 7, supra (legislative enactments must be presented to Governor and either signed by her or returned to legislature with written objections). See also INS v. Chadha, 462 U.S. 919, 103 S.Ct. 2764, 77 L.Ed.2d 317 (1983) (a provision of the Immigration and Nationality Act that authorized either house of Congress, by resolution, to veto a decision of the Executive Branch to allow a deportable alien to remain in the United States was unconstitutional; citing Article I, sections 1 and 7, of the Constitution of the United States, the Court held that the challenged provision violated the principle of separation of powers and allowed a legislative veto by less than a vote of each chamber).
Nevertheless, the statute as a whole need not be invalidated if the portions that have been found constitutionally impermissible are severable from the remainder. The severability of unconstitutional portions of a statute is governed by ORS 174.040, which provides:
"It shall be considered that it is the legislative intent, in the enactment of any statute, that if any part of the statute is held unconstitutional, the remaining parts shall remain in force unless:
"(1) The statute provides otherwise;
"(2) The remaining parts are so essentially and inseparably connected with and dependent upon the unconstitutional part that it is apparent that the remaining parts would not have been enacted without the unconstitutional part; or
"(3) The remaining parts, standing alone, are incomplete and incapable of being executed in accordance with the legislative intent."
Nothing in the text of ORS 459.298 provides that, if any part of that statute were held to be unconstitutional, the remaining parts should not remain in force. See ORS 174.040(1), supra.
Neither are the portions of ORS 459.298 relating to the establishment of the surcharge by EQC and to the bases of that surcharge "so essentially and inseparably connected with and dependent upon" the approval portions of the statute that it is apparent, either from the text or from the legislative history of the statute, that the former parts would not have been enacted without the latter. See ORS 174.040(2), supra. ORS 459.298 is part of a comprehensive statutory scheme of regulating solid waste, which includes many sections authorizing public bodies to impose fees to recover their costs.[10] The overriding purpose of ORS 459.298, as revealed by its text and context, is to permit the establishment and collection of fees.
*507 We also note, as did the Court of Appeals, the pertinent legislative history. The committee that considered HB 3515, which became Oregon Laws 1989, chapter 833, and which included the challenged provision, was told that "the Emergency Board does not have the approval authority[,] * * * it is a review and comment only." The committee instructed its staff to use "the toughest language we can have for E-Board control over the fee," but the legislature did not add a nonseverability provision. Tape Recording, Ways and Means Committee Subcommittee on Transportation and Regulation, June 24, 1989, Tape 155, Side B.
The legislature's permissible choice was between having no surcharge on the disposal of solid waste generated out of state and having a surcharge established by EQC without a veto by the Emergency Board or Joint Committee on Ways and Means. As between the two, we believe that the legislature intended to have a surcharge.
Finally, ORS 459.298 is neither incomplete, nor incapable of being executed, in the absence of the approval portions of the statute. See ORS 174.040(3), supra.
The portions of ORS 459.298 relating to approval of the surcharge by the Emergency Board or the Joint Committee on Ways and Means, being unconstitutional and severable, are deleted from the statute. The remaining portions of the statute shall continue in force.
Petitioners have made no other challenges under the Oregon Constitution to OAR 340-61-115(1) and 340-61-120(6), beyond those already discussed. We turn, therefore, to petitioners' claim that ORS 459.298, OAR 340-61-115(1), and OAR 340-61-120(6) impermissibly discriminate against interstate commerce in violation of Article I, section 8, clause 3, of the Constitution of the United States. For the following reasons, we conclude that they do not.
The Commerce Clause grants to Congress the power to regulate commercial transactions among the states, subject to the specific guarantees of the Constitution of the United States. By that grant of power to Congress, the Commerce Clause implicitly "limits the power of the States to discriminate against interstate commerce." Wyoming v. Oklahoma, ___ U.S. ___, ___, 112 S.Ct. 789, 800, 117 L.Ed.2d 1 (1992); see also New Energy Co. of Indiana v. Limbach, 486 U.S. 269, 273, 108 S.Ct. 1803, 1807, 100 L.Ed.2d 302 (1988) (stating that principle). As the Supreme Court of the United States has explained, "[t]his `negative' aspect of the Commerce Clause prohibits economic protectionism that is, regulatory measures designed to benefit in-state economic interests by burdening out-of-state competitors." New Energy Co. of Indiana v. Limbach, supra, 486 U.S. at 273-74, 108 S.Ct. at 1807-08.
Consistent with that proscription, states may not enact laws that discriminate against articles of commerce[11] coming from outside the state unless there is some reason, apart from their origin, for treating those articles differently. City of Philadelphia v. New Jersey, 437 U.S. 617, 626-27, 98 S.Ct. 2531, 2536-37, 57 L.Ed.2d 475 (1978). Cf. Chemical Waste Management v. Hunt, ___ U.S. ___, ___ _ ___, 112 S.Ct. 2009, 2013-15, 119 L.Ed.2d 121 (1992) (where the only discernible basis for an additional fee imposed on out-of-state waste was the origin of the waste, "invalidity under the Commerce Clause necessarily follows"). The burden is on the state to show that a differential charge "`is demonstrably justified by a valid factor unrelated to economic protectionism.'" Id. at ___, 112 S.Ct. at 2015 (quoting Wyoming v. Oklahoma, supra, ___ U.S. at ___, 112 S.Ct. at 801). See Fort Gratiot Landfill v. Mich. Dept. of Nat. Res., ___ U.S. ___, 112 S.Ct. 2019, 119 L.Ed.2d 139 (1992) (holding invalid on Commerce Clause grounds a *508 Michigan statute prohibiting landfills from accepting solid waste generated outside the county in which the landfill was located, unless the acceptance of such waste was explicitly authorized by the receiving county; after rejecting the state's argument that the restriction was justified on the ground that it treated waste from other Michigan counties no differently than waste from other states, and its argument that the statute constituted a "comprehensive health and safety regulation rather than `economic protectionism,'" the Court concluded that the state failed to advance "any legitimate reason for allowing [landfills] to accept waste from inside the county but not waste from outside the county").
We apply those principles to the statutes and regulations at issue here. ORS 459.297 requires EQC to promulgate regulations establishing a surcharge on the disposal of out-of-state solid waste. ORS 459.298 requires EQC to base the amount of that surcharge on the "costs to the State of Oregon and its political subdivisions of disposing of solid waste generated out-of-state which are not otherwise paid for" under other waste disposal programs, including costs arising from permit issuance, management, monitoring, and closure activities at disposal sites accepting out-of-state waste. On their face, OAR 340-61-115(1) and 340-61-120(6) purport to comply with those statutory mandates.
Because of the express nexus to actual costs incurred, we conclude that the surcharge authorized by ORS 459.297 and 459.298, and established by OAR 340-61-115(1) and 340-61-120(6), does not, on its face, constitute discrimination against an article of commerce, the origin of which is outside the state. There is a discernible basis for the surcharge apart from that origin. See City of Philadelphia v. New Jersey, supra, 437 U.S. at 626-27, 98 S.Ct. at 2536-37 (establishing that test). Through the statutory and regulatory criteria, the state has met its burden of showing that the surcharge "is demonstrably justified by a valid factor unrelated to economic protectionism." Chemical Waste Management v. Hunt, supra, ___ U.S. at ___, 112 S.Ct. at 2015.
We further conclude that, rather than being a constitutionally impermissible burden on out-of-state economic interests, New Energy Co. of Indiana v. Limbach, supra, the surcharge imposed on out-of-state waste by ORS 459.298 and its implementing regulations constitutes a "compensatory" fee for specific costs incurred by the state in the regulation of that waste. See Commonwealth Edison v. Montana, 453 U.S. 609, 621-22, 622 n. 12, 101 S.Ct. 2946, 2955-56, 2956 n. 12, 69 L.Ed.2d 884 (1981) (describing such fees). A law imposing a compensatory fee for costs incurred by a state in supervising and regulating the activities of an entity engaged in interstate commerce is prima facie reasonable. Great Northern Ry. Co. v. Washington, 300 U.S. 154, 160, 57 S.Ct. 397, 400-01, 81 L.Ed. 573 (1937). Such a law violates the Commerce Clause only where the amount of the fee is "manifestly disproportionate to the services rendered." Clark v. Paul Gray, Inc., 306 U.S. 583, 599, 59 S.Ct. 744, 753, 83 L.Ed. 1001 (1939). See Evansville-Vanderburgh Airport Authority Dist. v. Delta Airlines, Inc., 405 U.S. 707, 92 S.Ct. 1349, 31 L.Ed.2d 620 (1972) (fees reflecting a fair approximation of the use of facilities and not excessive in relation to costs incurred do not violate the Commerce Clause); Ingles v. Morf, 300 U.S. 290, 294, 57 S.Ct. 439, 441, 81 L.Ed. 653 (1936) (a fee burdening interstate commerce may be justified by showing that it constitutes "reimbursement for the expense of providing facilities, or of enforcing regulations of the commerce").
Petitioners contend that, even assuming that some fee could be imposed without offending the Commerce Clause, the present fees do offend the Commerce Clause, because they are "disproportionate." Such a claim cannot be adjudicated in the present proceeding. Our scope of review under ORS 183.400 precludes us from deciding whether the surcharge is impermissible as "disproportionate" to the services rendered or to the costs incurred by the State of Oregon in connection with *509 permitting waste disposal sites to accept solid waste generated out of state, because those are factual inquiries. As this court noted in AFSCME Local 2623 v. Dept. of Corrections, 315 Or. 74, 79, 843 P.2d 409 (1992), "judicial review under ORS 183.400 is limited to the face of the rule and the law pertinent to it. Numerous individual fact situations can arise under any rule, but judicial review of the rule as applied to each of those situations is reserved to other forums." Similarly, petitioners' claim of disproportionality may not be addressed in this proceeding under ORS 183.400.
The decision of the Court of Appeals is affirmed.
NOTES
[1] The Court of Appeals explained petitioners' interest in the surcharge:
"Petitioner Oregon Waste Systems, Inc. (OWS), owns and operates a regional solid waste disposal facility known as the Columbia Ridge Recycling Center and Landfill. It is located southwest of Arlington in Gilliam County. OWS disposes of waste generated in Oregon and also waste generated outside of Oregon. The operation provides direct and indirect benefits to petitioner Gilliam County as a result of employment in the county and the payment of local fees and taxes.
"Petitioner Columbia Resource Company, L.P. (CRC), has a 20-year contract with Clark County, Washington, under which it disposes of solid waste originating there. CRC uses the Finley Buttes Landfill in Morrow County as its disposal site. The operator of the Finley Buttes Landfill passes through to CRC the costs incurred for disposal, including charges made by respondent Department of Environmental Quality (DEQ)."
