### IN THE SUPREME COURT OF THE STATE OF WASHINGTON

HARLAN D. DOUGLASS and MAXINE H. DOUGLASS, husband and wife, Respondents,

V. SHAMROCK PAVING, INC., a Washington corporation. Petitioner. No. 94087-8

EN BANC 

### FILED ^ ^

FAIRHURST, C.J.—Landowners Harlan and Maxine Douglass (Douglass) 

### brought a private right of action against Shamrock Paving Inc. under the Model Toxics Control Act (MTCA), chapter 70.105D RCW, to recover costs incurred from 

### an allegedremedial action. Shamrock trespassed onto Douglass' vacant property and 

### spilledunknown amounts of lube oil. Douglass paid for soiltesting and soil removal to clean up his property and now seeks recovery of those costs under the MTCA. At issue is the interpretation of "remedial action" within the statute, whether the lubeDouglass V. ShamrockPaving,No. 94087-8



### oil on Douglass' property created a "potential threat" to human health or the environment, and which party is entitled to prevailing party status for purposes of 

### awarding attorney fees. RCW 70.105D.020(33), .080. We affirm the Court of Appeals' holding that Douglass' soil testing was a remedial action but his soil removal was not. We reverse the Court of Appeals' prevailing party designation because it was made prematurely. We remand the case to the trial court.

I. FACTS AND PROCEDURAL HISTORY A. Factual background Shamrock fueled its equipment,cleaned its machines,and stored its materials


### on Douglass'property while carrying out a paving project for the Washington State 

### Department of Transportation. Based on these activities, the trial court found that Shamrock spilled unknown amounts oflube oil onto theproperty.Lube oil is aheavy 

### oil (petroleum product)that is a "hazardous substance." RCW 70.105D.020(13)(d). After Shamrock's activities ceased, Douglass hired Tetra Tech Inc., an environmental consulting firm, to investigate the contamination on his property. Tetra Tech took three separate samples, measuring lube oil at 2,000 mg/kg, 800 

### mg/kg,and 400 mg/kg. After reviewing the samples,Douglass ordered Tetra Tech to perform a cleanup operation, removing 68 tons of soil from the property. After the cleanup, Tetra Tech took two additional samples, measuring lube oil at 220 mg/kg and at less than 100 mg/kg.Douglass V. Shamrock Paving,No. 94087-8

B. Procedural history Douglass initially sued Shamrock for trespass and nuisance. After testing the soil, Douglass amended the complaint to add a private right of action claim under the MTCA. The issues were bifurcated. A jury heard the trespass and nuisance claims and returned a verdict in favor of Douglass. The jury denied Douglass' request for cleanup costs. The judge heard the MTCA claim and found Shamrock had contributed to the release ofhazardous substances,but denied Douglass'private right of action because Douglass failed to prove that the lube oil was a threat to human health or the environment. The judge designated Shamrock as the prevailing party pursuant to the MTCA and awarded attorney fees. Douglass appealed,and the Court ofAppeals reversed.Douglass v. Shamrock Paving,Inc., 196 Wn.App.849,384P.3d 673 (2016).The CourtofAppeals focused
on whether Douglass conducted a "remedial action" and ultimately concluded that the soil testing (investigation) was a "remedial action" based on the statutory definition but the soil removal (cleanup)was not.Id. at 860.The court relied on the MTCA's plain language, finding that "remedial action" includes "actions and expenditures taken to discern whether a potential threat in fact poses a danger to human health or the environment." Id. at 857. The court distinguished Division Two's prior interpretation of "remedial action" because that case considered only cleanup costs,not investigative costs.Id. at 857-58 (referring to Seattle City Light v.Douglass V. ShamrockPaving,No. 94087-8



### Dep't ofTransp., 98 Wn.App. 165, 989 P.2d 1164 (1999)). Regarding Douglass' cleanup costs, the Court ofAppeals explained that "a cleanup effort must address a hazardous substance posing a threat or potential threat to human health or the environment." Id. at 859. The court deferred to the trial court's conclusion that the lube oil contamination did notmeetthis standard;thus,no recovery for cleanup costs
was warranted.Id. Since Douglass established the elements ofhis MTCA claim for investigative costs,the Court ofAppeals designated him the prevailing party entitled to recover attorney fees. Id. at 860. The court then remanded the case to the trial court to complete an assessment ofequitable factors to determine the exactrecovery
amount.Id. at 858. Shamrock sought review ofthe Court ofAppeals'decision.Douglass filed an answer asking the court to deny Shamrock's petition and filed a cross petition for review ofthe cleanup cost recovery. We granted review ofboth petitions.Douglass V. ShamrockPaving,Inc., 188 Wn.2d 1020,399 P.3d 1105 (2017).

II. ISSUES A. When lube oil contamination meets butdoes not exceed the Department ofEcology's (Ecology)cleanup level, can a party recover the cost ofinvestigative activities as remedial action costs under MTCA's private right ofaction? B. Does lube oil contamination that meets but does not exceed Ecology's cleanup level pose a potential threat to human health or the environment?Douglass V. ShamrockPaving,No. 94087-8



### C. Under the MTCA,is a party who recovers remedial action costs the 

### prevailing party,entitled to attorney fees,including costs on appeal?

III. ANALYSIS 

### The MTCA provides a private right ofaction to recover remedial action costs 

### (also referred to as a contribution claim). RCW 70.105D.080. The statutory claim provides that (a) "[r]ecovery of remedial action costs shall be limited to those remedial actions that, when evaluated as a whole,are the substantial equivalent ofa 

### department-conducted or department-supervised remedial action," (b) remedial action costs "shall include reasonable attorneys' fees and expenses," (c)the judge determines the recovery award "based on such equitable factors as the court 

### determines are appropriate," and (d)"[t]he prevailing party in such an action shall
recover its reasonable attorneys' fees and costs."Id. "Remedial action"is defined as 

### any action or expenditure consistent with the purposes ofthis chapter to identify, eliminate, or minimize any threat or potential threat posed 

### by hazardous substances to human health or the environment including any investigative and monitoring activities with respect to any release or threatened release of a hazardous substance and any health assessments or health effects studies conducted in order to determine the risk or potential risk to human health. RCW70.105D.020(33). 

### This case requires us to interpret both provisions, along with Ecology's 

### corresponding regulations. Statutory interpretation is a question oflaw reviewed de novo. Dep't ofEcology v. Campbell & Gwinn, LLC, 146 Wn.2d 1, 9, 43 P.3d 4Douglass V. ShamrockPaving,No.94087-8



### (2002)(citing State v. Breazeale, 144 Wn.2d 829, 837, 31 P.3d 1155 (2001);State V. J.M., 144 Wn.2d 472, 480, 28 P.3d 720 (2001)). When ascertaining the plain 

### meaning,the court considers the ordinary meaning ofwords,basicrules ofgrammar, and statutory context. Citizens All.forProp.Rights LegalFund v. San Juan County, 184 Wn.2d 428, 435, 359 P.3d 753 (2015) (citing In re Forfeiture of One 1970 Chevrolet Chevelle, 166 Wn.2d 834, 838-39, 215 P.3d 166 (2009)). Ifthe meaning ofthe statute is plain on its face, the court must give it effect. Campbell & Gwinn, 146 Wn.2d at 9-10.However,ifthe statute remains susceptible to multiple meanings, it is appropriate for the court to resort to aids to construction, including legislative history.Id. at 12(citing Cockle v. Dep'tof Labor &Indus., 142 Wn.2d 801,808, 16 P.3d 583 (2001); Timberline Air Serv., Inc. v. Bell Helicopter-Textron, Inc., 125 Wn.2d 305,312, 884 P.2d 920 (1994)). Based on our interpretation,we affirm the CourtofAppeals in partand reverse 

### in part. We affirm the Court ofAppeals' decision that Douglass' investigative costs
are recoverable remedial action costs but his cleanup costs are not. We reverse the 

### Court of Appeals' designation of Douglass as the prevailing party because that designation was premature.Douglass V. ShamrockPaving,No.94087-8

A. "Remedial action" includes investigative activities ofhazardous substances, but recovery ofthose costs may be limited 1. The plain meaning of "remedial action" includes investigative activities 

### The plain meaning of "remedial action" can be ascertained through the ordinary meaning of words and basic rules of grammar. The MTCA is "to be liberally construed," RCW 70.105D.910, yet the court will not put forth strained interpretations, Bird-Johnson Corp. v. Dana Corp., 119 Wn.2d 423,427, 833 P.2d 375 (1992)(citing Draper Mach. Works,Inc. v. Dep't ofNat. Res., 117 Wn.2d 306, 315, 815 P.2d 770 (1991)). The first clause of the "remedial action" definition 

### provides the operative meaning: "any action . . .to identify, eliminate, or minimize any threat or potential threat posed by hazardous substances to human health or the environment." RCW 70.105D.020(33). The second clause begins with "including," 

### which is generally construed as a term ofenlargement,not limitation.Id.;see Queets Band ofIndians v. State, 102 Wn.2d 1, 4, 682 P.2d 909 (1984). Specifically, the second clause enlarges the definition of "remedial action" to include "any 

### investigative and monitoring activities with respect to any release or threatened release ofa hazardous substance and any health assessments or health effects studies conducted in order to determine the risk or potential risk to human health." RCW 70.105D.020(33).I

Douglass V. ShamrockPaving,No.94087-8 The Court of Appeals correctly interpreted the term "remedial action." "Remedial action" includes investigative activities because it is plainly stated within the defmition-'remedial action" means "any action . . . including any investigative and monitoring activities." Id. Shamrock agrees that investigative activities are remedial actions, but only under limited circumstances. Shamrock argues that the 

### Court of Appeals effectively added words to the statutory definition of "remedial action" so that it includes actions "to identify [whether] . . . any threat or potential threat posed by hazardous substances [exists]." Id.\ Pet. for Review at 14. But 

### Shamrock's proposed interpretation is subject to the same alleged defect. Shamrock asserts that "'remedial action' means actions that result in the identification ofa threat or potential threat." Pet. for Review at 10. This assertion adds words to the statute because the definition makes no reference to the result ofan investigation. Douglass agrees with the Court ofAppeals'interpretation thatremedial action includes investigative activities. Suppl. Br. ofResp'ts at 8. The Court of Appeals 

### correctly interpreted the plain meaning of"remedial action"to include investigative activities because the legislature explicitly described those identifying activities as 

### "investigati[ons] . . . with respectto any release or threatened release ofa hazardous substance." RCW 70.105D.020(33). The investigations concern any release of a hazardous substance, not a specified quantity that exceeds the cleanup level. 

### Ecology, in its amicus brief, agrees that the outcome of the investigation is notDouglass V. ShamrockPaving,No. 94087-8



### dispositive. Amicus Curiae Br. ofEcology at 7. Based on the plain meaning ofthe statute, investigations of hazardous substances are remedial actions because their 

### purpose is to "discern whether such athreatexists."Douglass, 196 Wn.App.at 858. Douglass' soil testing was a remedial action under the MTCA because its purpose
was to investigate the release oflube oil. 2. Remedial action costs are not automatically recovered 

### The Court ofAppeals correctly refrained from making a final determination of Douglass' recovery amount because the case needed to be "remanded for an assessment of equitable factors." Id. Shamrock is not automatically liable for remedial action costs. Nonetheless, Shamrock argues that the Court of Appeals' 

### interpretation imposes a strict liability standard, forcing it to pay for investigatory activities without establishing a minimum level ofharm or culpability. Suppl.Br. of Pet'r at 13-14. Shamrock's argument is based on a misinterpretation ofthe statute. The MTCA imposes limitations on the recovery of remedial action costs. 

### Contrary to Shamrock's concerns,no provision provides automatic recovery ofany and all costs spent on remedial actions.Recovery is limited to remedial action costs that are the substantial equivalent of Ecology's remedial actions. Ecology is 

### empowered to "[ijnvestigate . . . any releases or threatened releases ofhazardous substances,including butnot limited to inspecting,sampling,or testing to determine the nature or extent ofany release or threatened release."RCW 70.105D.030(l)(a).

### Douglass V. ShamrockPaving,No.94087-8

"If there is a reasonable basis to believe that a release or threatened release of a 

### hazardous substance may exist, the department's authorized employees, agents, or 

### contractors may enter upon any property and conduct investigations." Id. Through its regulations, Ecology provides the steps for a typical cleanup process. First, a release of hazardous substances is reported to Ecology. WAC 173-340-120(2)(a). 

### Next, Ecology conducts an initial investigation. WAC 173-340-120(2)(b). An "initial investigation" is "an inspection of a suspected site by the department and documentation of conditions observed during that site inspection." WAC 173-340- 

### 310(1). Douglass' investigation was substantially equivalent to Ecology's initial 

### investigation, and the record supports the fact that there was a reasonable basis to believe that a release of hazardous substances occurred because of Shamrock's trespassory activities on the property. After the remedial action costs are defined, the judge determines the actual 

### recovery award based on "such equitable factors as the court determines are 

### appropriate." RCW 70.105D.080; see, e.g., PacifiCorp. Envtl. Remediation Co. v. Dep'tofTransp., 162 Wn.App.627,666,259 P.3d 1115 (2011)(affirming the trial court's equitable assessment);Dash Point Vill.Assocs. v. Exxon Corp.,86 Wn.App. 596, 607, 937 P.2d 1148, 971 P.2d 57 (1997)(affirming the trial court's equitable 

### assessment). IfShamrock had spilled one drop oflube oil and Douglass paid for an investigation ofhis entire property,the recovery may be little to none.In Seattle City

### Douglass V. ShamrockPaving,No.94087-8



### Light, the court explained the possible outcomes depending on the equitable assessment—^the liable party may have to pay for all remedial action costs, some 

### costs,or none at all. 98 Wn.App.at 175.This equitable assessmentprevents absurd

or unfair results. I 

### B. Compliance with cleanup levels protects,rather than threatens,human health and the environment 

### Douglass argues thatthe CourtofAppeals wrongly denied hisremedial action costs incurred through cleanup operations.To recover,Douglass mustprove thatthe hazardous substance poses a threat or potential threat to human health or the environment. RCW 70.105D.020(33); Seattle City Light, 98 Wn. App. at 170. 

### Douglass does not dispute this standard. Instead, Douglass argues that lube oil contamination of 2,000 mg/kg is a potential threat to human health or the environment. Suppl. Br. ofResp'ts at 10. 

### The MTCA instructs Ecology to maintain "minimum clean-up standards for remedial actions."RCW 70.105D.030(2)(e).Ecology defines "cleanup level" as the "concentration of a hazardous substance . . . that is determined to be protective of human health and the environment." WAC 173-340-200 (emphasis added).The soil 

### cleanup level for lube oil on unrestricted properties is 2,000 mg/kg.WAC 173-340- 900,tbl.740-1.The cleanup levelprovides a conservative metric such that exceeding 

### 2,000 mg/kg "do[es]not necessarily mean the soil mustbe restored to these levels." WAC 173-340-900, tbl.740-1, n.a. Conversely, Ecology may require a more 11

### Douglass V. ShamrockPaving,No.94087-8



### stringent cleanup level (less than 2,000 mg/kg) "when[,] based on a site-specific evaluation, [Ecology] determines that such levels are necessary to protect human health and the environment." WAC 173-340-704(3). Because Ecology never 

### performed a site-specific evaluation ofDouglass'property,this case doesnotpresent that situation. WithoutEcology's evaluation,it is appropriate to apply the published 

### cleanup levels to Douglass' property.' When Douglass elected to perform the cleanup,the lube oil contamination ranged from 400-2,000 mg/kg,which,according to Ecology's published cleanup levels, is "protective of human health and the environment." WAC 173-340-200; WAC 173-340-900, tbl.740-1. The trial court 

### and Court ofAppeals correctly concluded thatno potential threat existed.There was
no threat to eliminate or minimize and,thus,no remedial action costs to recover for cleanup.

' We defer to Ecology "on teehnieal issues based on Ecology's specialized expertise."Port ofSeattle v. Pollution ControlHr'gsBd., 151 Wn.2d 568,595,90P.3d 659(2004);see also Hillis V. Dep't ofEcology, 131 Wn.2d 373, 396, 932 P.2d 139 (1997)(substantial deference to agency views is appropriate "when an agency determination is based heavily onfactualmatters,especially factual matters which are complex,technical, and close to the heart ofthe agency's expertise"). Determining the level oflube oil that constitutes a threat or potential threat to human health or the environment is a technical issue requiring expertise. In the absence of Ecology's site-specifie evaluation,the court defers to the published cleanup levels. Furthermore,all three expert witnesses supported the trial court's conclusion thatthere was no threat or potential threat. Shamrock's expert, Jeff Lambert, an environmental scientist and engineer,opined thatthe lube oil atDouglass'property did notconstitute athreat orpotentialthreat to human health or the environment. Philip Leinart, an MTCA investigator at Ecology, agreed. Even Douglass' expert scientist from Tetra Tech, Jon Welge,after reviewing the lube oil results at 2,000 mg/kg,included a recommendation oftaking no action. 12Douglass V. Shamrock Paving,No. 94087-8

C. The prevailing party designation was made prematurely Under the MTCA, the prevailing party in a private right of action "shall
recover its reasonable attorneys' fees and costs." RCW 70.105D.080. The "prevailing party" is not defined,butthe meaning is clear—^the "prevailing party" is the party that either recovers remedial action costs or successfully defends against a claim for such costs. See Riss v. Angel, 131 Wn.2d 612, 633, 934 P.2d 669 (1997) ("In general, a prevailing party is one who receives an affirmative judgment in his
or her favor." (citing Schmidt v. Cornerstone Invs., Inc., 115 Wn.2d 148, 164, 795 P.2d 1143 (1990)));AllianceOne Receivables Mgmt.,Inc. v. Lewis, 180 Wn.2d389, 399, 325 P.3d 904 (2014) (requiring a final judgment before designating the prevailing party under RCW 4.84.250 and .270); Webster's Third New InternationalDictionary 1797(3d ed. 2002)("prevail" defined: "to gain victory by virtue of strength or superiority : win mastery"). The recovery amount, or percentage recovered in comparison to the amount sought, is not dispositive to 

### determine prevailing party status.^ In reference to the attorney fee provision in our civil forfeiture statute (RCW 69.50.505(6)), we explained that a '"prevailing party' is any party that receives some judgment in its favor." Guillen v. Contreras, 169

^ We recognize that "[t]he amount of recovery may be a relevant consideration in determining the reasonableness of a fee award," but this consideration has no bearing on the prevailing party status. Brand v. Dep't ofLabor & Indus., 139 Wn.2d 659, 666, 989 P.2d IIII (1999). 13Douglass V. ShamrockPaving,No.94087-8



### Wn.2d 769,775,238P.3d 1168 (2010)(emphasis added);see also Ennis v. Ring,56 Wn.2d 465, 473, 341 P.2d 885, 353 P.2d 950 (1959)("The prevailing party is the
one who has an affirmative judgment rendered in his favor at the conclusion ofthe 

### entire case."); Black's Law Dictionary 1298 (10th ed. 2014)(The "prevailing 

### party" is the "party in whose favor a judgment is rendered,regardless ofthe amount of damages awarded."). Therefore, prevailing party status depends on whether Douglass recovers his remedial action costs. 

### The Court ofAppeals required only "the elements ofa contribution claim"^ to prevail. Douglass, 196 Wn. App. at 860 (citing Taliesen Corp. v. Razore Land Co., 135 Wn.App. 106, 141, 144 P.3d 1185 (2006)). This,by itself, is insufficient. The equitable assessment must occur prior to designation of the prevailing party. Therefore,we remand the case to the trial court to conduct an equitable assessment. Ifthe trial court awards remedial action costrecovery for at least some ofDouglass' 

### costs,Douglass will be the prevailing party,entitled to attorney fees."^
IV. CONCLUSION 

### We hold that Douglass' investigative activities were remedial actions but his 

### recovery of investigative costs may be limited according to the court's equitable

^ As indicated in Part III, supra,the MICA private right of action is also referred to as a contribution claim. Douglass requested attorney fees in his cross petition for review. We deeline this request. Attorney fees will be awarded to the prevailing party,and that designation has not yetbeen made.
