CARSON, C. J.
At issue in this case is the constitutionality of two legislative enactments that fund projects designed to benefit Oregon’s environment. Petitioners Automobile Club of Oregon (Oregon AAA) and A & B Automotive and Towing Service, Inc. (A & B), timely petitioned for review of ORS 319.025 (the underground storage tank assessment)
and ORS 468A.425
et seq
(the emission fee).
Each legislative act conferred original-jurisdiction on this court to consider the petitions of any parties interested, affected, or aggrieved by that act.
Both parties have standing.
Petitioners ask this court to declare that each challenged statute violates Article IX, section 3a, of the Oregon Constitution.
That section provides, in part:
“(1) Except as [otherwise provided], revenue from the following shall be used exclusively for the construction, reconstruction, improvement, repair, maintenance, operation and use of public highways, roads, streets and roadside rest areas in this state:
“(a) Any tax levied on, with respect to, or measured by the storage, withdrawal, use, sale, distribution, importation or receipt of motor vehicle fuel or any other product used for the propulsion of motor vehicles; and
“(b) Any tax or excise levied on the ownership, operation or use of motor vehicles.”
Petitioners assert that (a) ORS 319.025 imposes taxes on motor vehicle fuel; (b) ORS 468A.425
et seq
impose taxes or excises on motor vehicle use or operation; and (c) neither statute dedicates the proceeds of those taxes to the narrow list of highway purposes permitted by Article IX, section 3a.
To violate Article IX, section 3a, the statute must both be a tax (under subsection (l)(a)) or a tax or excise
(under subsection (l)(b)),
and the revenue must be dedicated to purposes other than those constitutionally specified. We will examine each provision to determine whether the revenue derived therefrom levies a tax (in the case of motor vehicle fuel storage charges) or a tax or excise (in the case of emission fees) before turning to an inquiry about whether it is dedicated to a proscribed use.
I. THE UNDERGROUND STORAGE TANK ASSESSMENT
A. Background
Following the adoption of new environmental regulations governing underground storage tanks, Oregon’s retail gasoline station owners faced a potential crisis in 1991. Some legislators believed that, without state assistance, as many as half of the small, rural gasoline stations in this state would be forced to close.
See, e.g.,
Minutes, House Committee on Business and Consumer Affairs, June 4, 1991 (Exhibit D, Testimony of Senator Hill).
Senators Jim Hill and John Kitzhaber prepared a summary of the background of the provision later adopted as Oregon Laws 1991, chapter 863, section 18. That summary, set out below, was part of a letter requesting the Attorney General’s opinion about the constitutionality of the proposal; it is part of the legislative record.
“In late 1984, as part of the re-authorization of the Resource Conservation and Recovery Act, Congress passed national requirements affecting the underground storage of petroleum and other hazardous substances. Congress acted in response to increasing threats to the nation’s groundwater and to public safety from fire and explosions, as a result of spills and leaks from underground storage tanks. Oregon’s own experience with contaminated soil and groundwater and occasional public safety threats parallels the national experience.
“Based on this national legislation, the Environmental Protection Agency (EPA) adopted technical rules for new and existing tanks, financial responsibility rules and rules for State operation of the federal program. Compliance with technical standards for corrosion control, spill and overfill protection and leak detection is phased in between December 1989 and December 1998 depending on the age of the tank. Compliance with the financial responsibility requirement is phased in between January, 1989 and October
1991.
Because of insurance underwriting criteria that typically requires [sic] upgraded tanks and demonstration of a clean site, the financial responsibility deadlines are forcing businesses into an early decision on upgrades or site clean-up.
“In its fiscal and economic impact statement issued at the time of promulgation, EPA predicted that some 43 percent of all businesses with underground tanks would close because of the predicted compliance costs. What is now becoming clear, is that the closures are not, and will not, be random. Rather, smaller businesses in more rural locations are going to be closing in disproportionate numbers because of the inability to absorb new debt of the magnitude necessary to comply. Our own estimate is that as many as 1000 gasoline retailers may not have the financial capacity to comply with these federal mandates.” Minutes, Senate Committee on Business, Housing & Finance, May 23, 1991 (Exhibit B, Letter from Senator Hill to then-Attorney General Dave Frohnmayer, at 3).
By adopting Oregon Laws 1991, chapter 863, section 18, the legislature ordered the state to collect an “underground storage tank assessment” from any person taking delivery, into an underground storage tank, of gasoline
intended for resale. The word “tax” was avoided in the new law in an apparent effort to avoid conflict with the Oregon Constitution.
See
Or Laws 1991, ch 863, § 20(1) (“It is the intent of the Legislative Assembly that funds assessed pursuant to section 18 of this-Act are not subject to the provisions of section 2, Article VIII or section 3a, Article IX of the Oregon Constitution.”). Reviewing the application of Article IX, section 3a(l)(a), to the proposed assessment before the statute imposing it was adopted, the Attorney General opined that the assessment was not a tax for purposes of the constitutional provision, but warned that this conclusion was “not free from doubt.” Letter of Advice dated May 20, 1991, to Senator Jim Hill (Op-6413).
B. Is The “Assessment” a “Tax”?
For its conclusion that the underground storage tank assessment was not a tax, the Attorney General’s letter of advice relied on a distinction between taxes and assessments established by this court’s interpretation of provisions of the Oregon Constitution other than those limiting fuel revenues to highway uses, namely provisions that require uniformity in taxation.
Id.
We next consider whether the underground storage tank assessment is a tax and whether the distinction between taxes and assessments in the uniformity cases applies to Article IX, section 3a(l)(a).
In the most general sense, a tax is “any contribution imposed by government upon individuals, for the use and service of the state, whether under the name of toll, tribute, tallage, gabel, impost, duty, custom, excise, subsidy, aid, supply, or other name.” Black’s Law Dictionary 1457 (6th ed 1991). An assessment is a government fee imposed on owners of property to finance improvements or services directly
benefiting that property; an assessment is exempt from constitutional limitations requiring that taxes be uniformly imposed so long as the financial burden and the private benefit are closely related.
King v. Portland,
38 Or 402, 63 P 2 (1900),
aff'd,
814 US 61, 22 S Ct 290, 46 L Ed 431 (1902).
The language used in this court’s decisions on assessments has evolved to suggest that, in the uniformity context, an assessment is not a tax at all.
Compare Sproul v. State Tax Com.,
234 Or 579, 383 P2d 754 (1963) (fireprotection assessments on forest lands exempt from uniformity limitations because not an exercise of state’s “taxing power”),
with Dennehy v. Dept. of Rev.,
305 Or 595, 604 n 3, 756 P2d 13 (1988) (disapproving distinction for these purposes between state’s “taxing power” and “police power” and focusing, instead, on “whether a law imposes a ‘tax’ within the meaning of constitutional rules governing taxation”).
Petitioners, the state, and
amici
have presented extensive arguments about whether attributes of the underground storage tank assessment align burdens and benefits closely enough to support a “special assessment” label. Although the “assessment” label may well be accurate, we decline to apply the distinction found in the context of the uniformity clauses to the context of Article IX, section 3a.
Article IX, section 3a, and its pre-1980 predecessor,
former
Article IX, section 3, were adopted to ensure that revenue from motor vehicles and motor vehicle fuel would be devoted solely to specified highway purposes.
The purpose
of Article IX, section 3a, is to prevent revenue raised from taxes related to motor vehicles and motor vehicle fuel from being diverted to impermissible non-highway purposes.
Rogers v. Lane County,
307 Or 534, 541, 771 P2d 254 (1989) (“In short, this constitutional amendment made it clear and unambiguous that the people of Oregon wanted monies derived from taxes and fees on motor vehicles and motor vehicle fuels to be used only for highway purposes”). We hold that the underground storage tank assessment is a “tax” under Article IX, section 3a(l)(a), and that, no matter what label the legislature may attach to a tax on motor vehicle fuel, whether it be “fee,” “excise,” “tithe,” “assessment,” or some other term, the revenues derived therefrom must be dedicated to the listed purposes.
A case deciding whether an assessment was a tax under a funding-dedication provision comparable to Article IX, section 3a, supports our conclusion. In
Northwest Natural Gas Co. v. Frank,
293 Or 374, 648 P2d 1284 (1982), this court interpreted Article VIII, section 2, the constitutional provision committing taxes measured by the sale of natural gas and oil to the Common School Fund, and Article IX, section
3b, the constitutional provision limiting the permissible amount of such taxes. The 1971 legislature had authorized the Department of Energy (DOE) to fund its operation by assessing fees against energy resource suppliers on an energy-resources-sold basis. In 1980, the electorate voted to adopt a constitutional amendment, adding Article VIII, section 2, and Article IX, section 3b. When the 1981 legislature provided authority to DOE to continue to assess the energy supplier fees as before, it provided for direct judicial review of whether the assessment ran afoul of the 1980 constitutional amendments. On review, this court held that the DOE assessments, despite their “assessment” label, were indeed taxes subject to Article VIII, section 2, and Article IX, section 3b, of the Oregon Constitution. 293 Or at 383-84.
The “assessment” (rather than “tax”) label attached by the legislature to the charge for filling an underground storage tank, like the label attached to the DOE assessments in
Northwest Natural Gas Co. v. Frank, supra,
is important but not dispositive on the issue of whether that assessment is a tax under Article IX, section 3a.
See Sproul v. State Tax Com., supra,
234 Or at 581 (“The label the legislature places on a levy is an important factor to be considered in determining into what category to place the levy. However, such a label is not conclusive of the nature of the levy.”). This court decided in
Northwest Natural Gas Co. v. Frank, supra,
that a fee imposed by government may be a “tax” in certain constitutional contexts despite the fact that the fee is called an “assessment” and that it burdens those benefited.
The clear purpose of Article IX, section 3a(l)(a), is to prevent diversion from the Highway Fund of money raised from burdens imposed on motor vehicle fuel. Article IX, section 3a, refined and restricted
former
Article IX, section 3, which, according to one description in the 1942 Voters’ Pamphlet, was intended to “effectuate a basic democratic principle, that of direct control by the people, insofar as is reasonable, of the expenditure of tax monies.” The people of Oregon have directed that
all
government revenues from motor vehicle fuel taxes be expended for specified highway purposes; we must honor that direction.
The underground storage tank assessment is measured by the receipt of motor vehicle fuel into storage tanks.
The limitations of Article IX, section 3a(l)(a), apply to
“[a]ny tax
levied on, with respect to, or
measured by
the storage, withdrawal, use, sale, distribution, importation or
receipt of motor vehicle fuel.”
(Emphasis added.) We conclude that, despite the “assessment” label attached to the levy, the underground storage tank assessment is a tax on motor vehicle fuel (a “gasoline tax”) under Article IX, section 3a(l)(a).
The next step in our analysis is to determine whether ORS 319.025 dedicates the proceeds of the gasoline tax to those uses permitted by Article IX, section 3a.
C. Permissibility of Intended Use
The funds raised from the tax levied in ORS 319.025 are dedicated to the Underground Storage Tank Compliance and Corrective Action Fund created under ORS 466.791. That fund, administered by the Department of Environmental Quality, is earmarked for programs providing grants, loans, loan guarantees, interest rate subsidies, and insurance premium copayments to owners of underground storage tanks. ORS 466.791(5).
The legislative purpose in levying the assessment was to maintain public access to gasoline fuel in rural Oregon by ensuring that the owners of rural gasoline stations received financial assistance to comply with increasingly stringent federal environmental regulations. The bill’s sponsor explained:
“Today Oregonians face what could be a significant crisis. The Environmental Protection Agency has set certain requirements on all the retail deliverers of petroleum throughout the entire country. If we in Oregon do not do something now, as many as fifty percent of all the retail gas stations that were* * * in our home towns and along the freeways will be closed because they will be unable to meet those requirements.” Minutes, House Committee on Business & Consumer Affairs, June 4, 1991 (Exhibit D, Testimony of Senator Jim Hill).
The state and
amicus
Oregon Petroleum Marketers Association (OPMA) contend that those purposes are permissible under Article IX, section 3a, because they fund the “improvement[,] * * * operation and use of public highways.”
See
Or Const, Art IX, § 3a (listing these and other permissible uses). This court closely examined the quoted language in
Rogers v. Lane County, supra,
interpreting it to permit funding of “other projects or purposes within or adjacent to a highway, road, street or roadside rest area right-of-way that primarily and directly facilitate motorized vehicle travel.” 307 Or at 545.
The argument of the state and
amicus
OPMA is that gasoline stations are adjacent to highways and that the funded projects will keep the stations from closing, thus facilitating motor vehicle traffic. According to the state, “[ajbsent the action of the 1991 legislature in enacting SB 1215, motorists in Oregon would have been faced with the prospect of not being able to use the state’s highways and roads due to a dearth of gas stations and a lack of available fuel.”
Amicus
OPMA. points put: “Motorists cannot use the state’s roads without motor fuel.” It is true that gasoline stations are necessary to the use of highways, but so are automobile repair shops and businesses selling batteries, tires, mufflers, and the like. The people, in adopting Article IX, section 3a, surely did not consider support of gasoline stations any more a highway purpose than support of automobile repair or tire sale businesses or, for that matter, roadside cafes and motels.
We construe Article IX, section 3a, narrowly.
All funds from the new gasoline tax are dedicated to the Underground Storage Tank Compliance and Corrective Action Fund described in ORS 466.791. We conclude that the expenditures authorized in ORS 466.791 are not permissible under Article IX, section 3a. The fund clearly does not provide for
construction, improvement, repair, maintenance, or use of highways. Neither does it fall within the meaning that this court has attached to “operation and use” of ahighway,
viz.,
it does not “primarily and directly facilitate motorized vehicle traffic.”
See Rogers v. Lane County, supra,
307 Or at 545 (stating the test). The fund facilitates motorized vehicle traffic only tangentially; its primary beneficiaries are not users of highways but owners of gasoline stations.
We conclude that the underground storage tank assessment established in ORS 319.025 is an unconstitutional tax.
II. THE EMISSION FEE
The emission fee imposed by ORS 468A.435 was enacted by the 1991 legislature as part of House Bill 2175. Or Laws 1991, ch 752. As the state describes it, HB 2175 was “a broad-based response to the problems of air pollution in this state and to the imperatives of federal legislation requiring the states to take action to remedy air pollution problems.” The Legislative Assembly declared that the purposes of the Act were to:
“(1) Insure that the state meets its minimum obligations under the Clean Air Act Amendments of 1990.
“(2) Avoid direct regulation of industrial sources of air pollution through a Federal Government administered permit program.
“(3) Prevent imposition of Clean Air Act sanctions which would impound federal highway funds appropriated for the state and increase emission offset requirements for new and expanding major industrial sources of air pollution.
“ (4) Provide adequate resources to fully cover the costs of the Department of Environmental Quality to develop and administer an approvable federal operation permit program in accordance with the Clean Air Act, including costs of
permitting, compliance, rule development, emission inventorying, monitoring and modelling and related activities. ’ ’ Or Laws 1991, ch 752, § 2.
Finding that the effects of motor vehicle emissions on air quality could be ameliorated by public transportation, development of alternative fuels, carpools, vanpools, and other measures, ORS 468A.425(3), the legislature earmarked fees imposed at the time of vehicle registration to the Department of Transportation Public Transportation Development Fund. ORS 468A.440(2).
See
ORS 184.733 (establishing and describing purposes of the fund).
B. Is the Fee a “Tax or Excise”?
Article IX, subsection 3a(l)(b), dedicates to highway purposes the revenue derived from “[a]ny tax or excise levied on the ownership, operation or use of motor vehicles.” The broad legislative intent that we recognized in the context of subsection 3a(l)(a) applies with equal force to subsection 3a(l)(b).
Accordingly, we interpret the term “tax,” which is discussed above with respect to subsection 3a(l)(a), the same in the context of subsection 3a(l)(b). An “excise” is “[a] tax imposed on the performance of an act, the engaging in an occupation, or the enjoyment of a privilege.” Black’s Law Dictionary 563 (6th ed 1991);
see Pacific First Federal v. Dept. of Rev.,
308 Or 332, 779 P2d 1033 (1989) (corporate excise tax is a privilege tax exacted for the privilege of earning a net income in this state);
Eugene Theatre v. Eugene,
194 Or 603, 629, 243 P2d 1060 (1952) (a municipal occupation tax is an excise). A tax on use or operation of motor vehicles ordinarily is properly deemed an excise, because it taxes the enjoyment of a privilege.
The state asserts that the emission fee is not a “tax or excise” on the use or operation of motor vehicles. Instead, the state characterizes the emission fee as a graduated charge for pollution of the airshed, based on the year of manufacture of a vehicle.
This position is consistent with the Legislative
Assembly’s assertion in the challenged Act that
“[a]n emission fee
based on the amount of pollutants emitted by motor vehicles
is not a tax or excise
on the ownership, operation or use of motor vehicles.” ORS 468A.425(6). (Emphasis added.)
As we concluded in our discussion of the distinction between assessments and taxes, ante, the character of a levy is determined by its function, not by the label the legislature attaches to it.
See Dennehy v. Dept. of Rev., supra,
305 Or at 604 (stating the rule);
Sproul v. State Tax Com., supra,
234 Or at 581 (same).
The emission fee is to be collected at the time certain vehicles are registered or when registration is renewed. ORS 468A.440. Although payment of the fee is not a condition of registration, a civil penalty may be assessed for non-payment of the emission fee. ORS 468A.430. Only vehicles registered under ORS 803.420(1) (passenger cars) are assessed the fee. ORS 468A.430(1).
Graduation of the fee, with older vehicles assessed more than newer ones, does not persuade us that the fee is a “special assessment” unrelated to registration.
See Sproul v. State Tax Com., supra
(discussing requisites of special assessments).
Registration is intrinsically and necessarily a requisite of the “ownership, operation or use of motor vehicles.”
See
ORS 803.300 (registration is requisite of owning a vehicle in this state; failure to register is a Class C traffic infraction). We hold that the emission fee is a “tax or excise levied on the ownership, operation or use of motor vehicles” under Article IX, section 3a(l)(b), of the Oregon Constitution. We reach the same conclusion by accepting the state’s characterization of the emission fee as a charge for polluting the airshed, because polluting the airshed is an inescapable incident of the operation or use of motor vehicles, and a state-imposed “fee” or “charge” for operating or using a vehicle is a tax or excise on its operation or use for purposes of Article IX, subsection 3a(l)(b).
C. Permissibility of Intended Use
The uses established for the Public Transportation Development Fund are many. The state and
amici
Oregon Transit Association and Tri-Met urge that at least some of them are permissible purposes under Article IX, section 3a. For instance, they urge that transportation demand management projects
supported by the fund are for the “improvement, * * * operation and use” of highways, as this court construed that phrase in
Rogers v. Lane County, supra.
They appear to concede that other projects funded by the emission fee
(e.g.,
research into alternative fuels and acquisition of buses) are impermissible unless this court adopts a broader test, such as the one proposed by the dissent in
Rogers, viz.,
‘ ‘improves the operation and use of a highway, road, street, or roadside rest area.” 307 Or at 553. As noted earlier in this opinion, we decline to adopt a new test.
Under the existing test, we conclude that the majority of public transportation projects to be funded by the emission fee are impermissible. As petitioners point out, the people of this state on three separate occasions have considered and rejected proposals to amend Article IX, section 3a, to fund public transportation by motor vehicle fuel and/or registration taxes.
We will not do by reconstructive interpretation what the drafters did not do and what the electorate has declined to do.
When some proposed uses of the emission fee are permissible and some are not, we will not redraft the statute to save the permissible uses.
See Northwest Natural Gas Co. v. Frank, supra,
293 Or at 381 (role of court is to interpret, not redraft, statutes). We hold that ORS 468A.425 to 468A.450, the 1991 statutes imposing an emission fee on
certain motor vehicles, violate Article IX, section 3a, of the Oregon Constitution and thus are invalid.
III. CONCLUSION
The underground storage tank assessment is a ‘ ‘tax’ ’ and the vehicle emission permit fee is a “tax or excise.” The purposes to which the legislature would have dedicated the funds raised by the challenged provisions, no matter how laudable, are constitutionally impermissible. The provisions adopted as Oregon Laws 1991, chapter 863, section 18, and codified as ORS 319.025, and those adopted as Oregon Laws 1991, chapter 752, sections 14 to 14e, and codified as ORS 468A.425 to 468A.450, violate Article IX, section 3a, of the Oregon Constitution and, therefore, are invalid.
