¶ 2. Vermont regulations require all gasoline dispensing facilities with an annual throughput of 400,000 or more gallons per year to install a Stage II vapor recovery system to capture harmful volatile organic compounds that would otherwise escape into the atmosphere when vehicle gas tanks are filled. See Air Pollution Control Regulations, Stage II Vapor Recovery Controls at Gasoline Dispensing Facilities, 7 Code of Vt. Rules § 5-253.7(a)-(d), at 12 031 001 - 36.1-36.2. Under the regulatory schedule, any gas station that sells 1,200,000 or more gallons per year must cease all gasoline transfers after December 31,1997 unless and until an approved Stage II system is installed. Id. § 5-253.7(c)(l), (g)(1), at 12 031 001-36.1,36.5.
¶ 3. Deso owned and operated a self-service gas station in St. Albans from August 31, 1990 until he sold the station to Bradford Oil on June 30,1999. During that time, he installed underground return piping for a gravity-feed Stage II vapor recovery system, but never installed the above ground components. Shortly after the sale, tests by the new owner showed
¶ 4. A year later, the Secretary of the Agency of Natural Resources (ANR) issued an administrative order and imposed a $27,050 penalty pursuant to the state’s Uniform Environmental Law Enforcement Act (UELEA), 10 V.SA. §§ 8001-8018, finding that Deso had (1) submitted false written reports to the Air Pollution Control Division regarding gasoline sales; (2) failed to pay the proper petroleum assessment fees, and (3) failed to install a Stage II vapor recovery system. After Deso requested a hearing before the environmental court pursuant to § 8012(a), the Secretary amended the administrative order by raising the assessed penalty to $44,000 and reserving the right to augment the penalty based on evidence to be presented at the hearing regarding the amount of economic benefit Deso gained from the violations.
¶ 5. Based on the evidence at the hearing, the environmental court found that Deso had substantially underreported his actual gasoline sales, failed to pay the petroleum assessment fee on the actual sales volume, and knowingly operated his gas station without a Stage II vapor recovery system from January 1, 1998 until June 30,1999. The court determined that during those eighteen months approximately 14,627 pounds of volatile organic compounds were released into the air. The court also found that the original underground piping was either not installed properly in 1994, or had failed by the time Deso sold the station in the summer of 1999.
¶ 6. Pursuant to 10 V.S.A § 8012(b)(4), the environmental court reviewed anew the penalty to be assessed against Deso, using the eight criteria set forth at § 8010(b). Regarding Deso’s failure to install the required Stage II vapor recovery system, the court determined that Deso gained two types of economic benefits. First, the court held that Deso gained ten cents per gallon profit, or $161,264, by illegally selling gasoline between January 1, 1998 and June 30, 1999. Second, the court determined that Deso benefitted by avoiding the costs of installing and maintaining the vapor recovery system, including $8,070 to install the above ground components and $5,000 to dig up and replace the faulty underground piping. Pursuant to § 8010(b)(6), the court assessed $26,140, or twice the avoided costs. The court further determined that Deso knew or had reason to know the violation existed, and that it caused an actual impact on the environment and a potential for harm to the health of users and neighbors of the facility, but assessed no penalty for these factors. In total, the court fined Deso $200,474 for selling gasoline without a Stage II vapor recovery system, $5,000 for submitting false written reports, and $4,800 for underpaying the proper petroleum assessment fee. Pursuant to § 8010(c), the court reduced the total penalty to $100,000. Deso now appeals the penalty imposed for his violation of the Stage II regulation.
I.
¶ 7. Deso’s first contention is that the court erred by determining that his so-called “wrongful profits” — $161,264 earned from the sale of gasoline without an approved emission cоntrol system — was an economic benefit gained from the violation. We agree. In calculating the amount of a penalty under UELEA, the environmental court must consider all of the statutory criteria set forth in § 8010(b), including “the economic benefit gained from the violation.” 10 V.S.A. § 8010(b)(5); Agency of Natural Res. v. Godnick,
¶ 8. At the time he became subject to the regulations, Deso had at least two means of compliance: spending $13,070 to install a Stage II vapor recovery system, or the vastly more expensive alternative of ceаsing production altogether, which the court found would mean forgoing $161,264 in profits. Economic principles, normal business behavior, and common sense suggest that a rational business would choose to install the required equipment. Thus, the unfair economic advantage Deso gained over his competitors is the savings gained by not installing an approved Stage II vapor recovery system. Using a wrongful profits analysis significantly overinflates the actual economic benefit to the violator; rather than leveling the playing field, it puts him or her at a marked disadvantage. See R. Fuhrman, et al., Consideration of “Wrongful Profits” in Environmental Civil Penalty Cases, 29 Env’t Rep. 1010, 1011 (1998) (“economic benefit calculation must be based on the compliance choice a rational business would make and should reflect the least costly means of compliance”); see also M. McGuire, Muddying the Waters: “Wrongful Profits” as a Measure of Economic Benefit to Violators of the Clean Water Act in the Wakе of United States v. Union Township, 9 Dick. J. Envtl. L. & Pol’y 361, 378 (2000) (“The wrongful profits analysis may serve to over-inflate the actual enjoyed benefit of noncompliance.”).
¶ 9. ANR argues that our prior eases affirm the view that any profit realized from a prohibited activity is properly defined as an economic benefit under 10 V.S.A. § 8010(b)(5). See Sec’y v. Earth Constr., Inc.,
¶ 10. ANR also warns that disgorging companies of profits earned by ignoring Vermont’s environmental programs is necessary to deter others from committing similar violations. While we agree that such a deterrent may be necessary — indeed, Vermont’s environmental programs would cease to function if per-mittees were allowed to unilaterally disregard permit requirements — for the reasons above we do not think so-сalled “wrongful profits” can be calculated as an economic benefit. Rather, we note that 10 V.S.A. § 8010(b)(6) provides for penalties in order to achieve deterrence, and that the environmental court had the discretion to set Deso’s penalty at the same level based on other § 8010(b) factors without relying on an incorrect theory of economic benefit. See Agency of Natural Res. v. Duranleau,
¶ 11. Generally, the calculation of a final penalty under UELEA, particularly the calculation of economic benefit, will be imprecise. See Pub. Interest Research Group of N.J. v. Powell Duffryn Terminals, Inc.,
II.
¶ 12. Deso next argues that the environmental court exceeded the maximum penalty allowable under UELEA. He contends that 10 V.S.A. § 8010(c) limits penalties for violations of Vermont’s Air Pollution Control Regulations to $25,000 per viоlation, and that the statute’s $10,000 per day additional allowance for continuing violations applies only to violations that continue after the initial penalty is assessed, not, as here, to violations that ceased prior to notice of violation. Since this claim was not raised before the environmental court, it is not preserved for our review. Earth Constr., Inc.,
¶ 13. UELEA provides that as part of an administrative order:
A penalty of not more than $25,000.00 may be assessed for each determination of violation. In addition, if the secretary determines that a violation is continuing the secretary may assess a penalty ofnot more than $10,000.00 for each day the violation continues. The maximum amount of penalty assessed under this subsection shall not exceed $100,000.00.
10 V.S.A. § 8010(c). Deso asserts that by using the present tense in the phrase “is continuing” and the word “continues,” the Legislature intendеd to restrict application of the $10,000 per day allowance solely to active, ongoing violations. Deso would thus interpret the second sentence of § 8010(c) as a contempt provision, authorizing an additional fine of not more than $10,000 per day to be levied against violators who persist in their misconduct after receiving notice of violation and penalty. ANR asserts that a continuing violation under § 8010(c) means any violation that persists more than one day, and that notice of penalty is not required. We find that the latter is the proper construction of the statute.
¶ 14. References to continuing violations appear in almost fifty penalty statutes in Vermont, yet none define “continuing violation” or a “violation that is continuing.” ANR’s Environmental Administrative Penalty Rules interpreting § 8010(c) provide a definition:
Continuing Violation: The Secretary may consider any violation of a statute listed in 10 V.S.A. Section 8003(a) or a rule promulgated under such statute or a condition of a related permit, order, or assurance of discontinuance that continues longer than one day as a continuing violation subject to additional penalties for each day of continuance of the violation.
6 Code of Vt. Rules § 106, at 12 030 002-4 (emphasis added). We conclude that the highlighted portion of this definition is correct for three reasons. First, an administrative agency’s interpretation of a statute within its area of expertise is presumed to be correct, valid, and reasonable. In re Prof'l Nurses Serv., Inc,,
¶ 15. This does not, however, answer the question of whether prior notice is required under § 8010(c) before cumulative penalties may be assessed. We conclude that notice is not required. First, when the Legislature intends that a violator be on notice before cumulative penalties
¶ 16. Second, the legislative history of UELEA evinces an intent not to require notice. As originally introduced in 1989, § 8010(c) provided that “in the case of a continuing violation, each day’s continuance may be deemed a separate and distinct offense.” 1989, S. 54 (Vt. Bien. Sess.). The Senate twice amended this language to require either notice, an order, or a warning before allowing assessment of cumulative daily penalties. See Sen. Jour. 301, 312 (Mar. 30, 1989 Vt. Bien. Sess.). The Legislature, however, ultimately accepted the House version, which deleted the requirement that additional penalties may apply only after receipt of a notice, order, or warning. See House Jour. 787 (May 2, 1989 Vt. Bien. Sess.); Sen. Jour. 643 (May 2, 1989 Vt. Bien. Sess.); 1989, No. 98, § 1 (codified as amended at 10 V.S.A. § 8010(c)). This Court will reject construction of an ambiguous statute where amendments to the same effect were expressly rejected by the Legislature. See In re Lunde,
¶ 17. Third, the construction Desо seeks would conflict with UELEA’s statute of limitations provision, 10 V.S.A. § 8015. Section 8015(2) requires actions brought under the Act to commence within six years from the date a continuing violation ceases. It would be nonsensical to simultaneously require notice, i.e., filing an administrative order, prior to establishing a continuing violation and at the same time set the statute of limitations for taking action, i.e., filing administrative orders, at six years after a continuing violation ceases.
¶ 18. Finally, we note that UELEA is a remedial statute and, as such, it must be construed liberally “so as to furnish all the remedy and accomplish all the purposes intended.” State v. Custom Pools,
¶ 19. Thus, we hold that continuing violations under 10 V.S.A. § 8010(c) may include any violation that persists longer than one day, regardless of whether the violation is currently ongoing or has ceased. We disagree with Deso’s contention that this means that the Secretary may issue a $100,000 fine any time a violation lasts longer than ten days. Deso fails to understand that 10 V.S.A. § 8010(c) sets only the maximum penalty. To fix the actual penalty amount the Secretary must apply the criteria set forth in § 8010(b).
III.
¶ 20. Finally, Deso asserts that in calculating the costs he avoided through noncompliance the environmental court erred by including $5,000 to dig up and replace the underground piping for the Stage II vapor recovery system. Deso contends that because no evidence was given at trial proving that the underground pipes had failed before Deso sold the station, it was clear error for the court to conclude that he would have had to replace the pipes had he timely installed a Stage II vapor recovery system. We disagree.
¶ 21. We will affirm the trial court’s findings of fact unless, “viewing the evidence in the light most favorable to the prevailing party and excluding the effect of modifying evidence, a finding is clearly erroneous.” Houle v. Quenneville,
¶ 22. At trial, Douglas Cone, the manager of the firm that originally installed the underground pipes in 1994, testified that the pipes would most likely have malfunctioned because of a design error, defective installation, or lifting due to frost heaves. The uncontested evidence at trial showed that Deso installed only minimal frost proofing above the pipes, that he never caused the pipes to be tested, and that the new owner had the pipes tested and discovered the failure within months
¶ 23. Additionally, we find Deso’s attempt to claim credit for work left incomplete and unmaintained since 1994 wholly unpersuasive in light of the regulatory requirements he ignored. See Air Pollution Control Regulations, Stage II Vapor Recovery Controls at Gasoline Dispensing Facilities, 7 Code of Vt. Rules § 5-253.7(e)(l)(i), at 12 031 001 — 36.4. (requiring initial testing of underground piping to verify propеr installation and functioning); id. § 5-253.7(d)(3) (requiring a gas station owner to inspect and maintain all components of a Stage II vapor recovery system in good working order); id. § 5-253.7(d)(5), (6), at 12 031 001 — 36.3 (requiring immediate replacement of any defective components).
¶ 24. The environmental court’s determination of the maximum statutory penalty and Deso’s economic benefit for avoided costs are affirmed. The court’s determination that Deso’s economic benefit also included all profits earned frоm gasoline sales in violation of Air Pollution Control Regulation § 5-253.7 is reversed, and the cause is remanded.
The penalty calculation of the economic benefit Deso gained by avoiding costs is affirmed. The penalty calculation of the economic benefit Deso gained by transferring gasoline in violation of the Air Pollution Control Regulation § 5-253.7 is reversed, and the matter is remanded for further proceedings consistent with this opinion.
Note: Justice Dooley sat at oral argument but did not participate in this decision.
