   OPINION OF THE COURT

RENDELL, Circuit Judge.

F.P. Woll & Company (“Woll”) appeals from the judgment of the District Court granting it substantial relief against Fifth and Mitchell Street Company (“Fifth Street”), the previous owner of Woll’s contaminated site, and Eaton Laboratories, Inc. (“Eaton”), a former tenant that manufactured dry cleaning chemicals at the site. Woll contends that the relief granted following a bench trial and a jury trial — an award of $346,958.00 and declaratory relief against the defendants for future response costs and contribution under the Comprehensive Environmental Response Compensation and Liability Act (“CERCLA”), 42 U.S.C. §§ 9607(a), 9613(f), and the Pennsylvania Hazardous Sites Cleanup Act (“HSCA”), 35 P.S. § 6020.101 et seq., and against Eaton for similar costs under the Pennsylvania Storage Tank and Spill Prevention Act (“STSPA”), 35 P.S. § 6021.101 et seq. — was not substantial enough. Woll urges that the Court should have granted a monetary award for future clean-up costs, and should have permitted recovery of the amount it would have received from an aborted sale of the site as an element of damages. We, like the District Court, reject both of these claims. Woll also levels four other attacks based on the District Court’s handling of other aspects of the case. We deal with these summarily below.

Woll seeks reimbursement for future clean-up costs under the STSPA and the HSCA. The District Court denied relief on the basis that future response costs were too speculative to support a monetary judgment. We concur. Woll concedes that neither the Environmental Protection Agency (“EPA”) nor the Pennsylvania Department of Environmental Protection has indicated that further remedial action is necessary or demanded payment from Woll for future response costs. A. 805. In fact, the EPA omitted the Site from its inventory of possible groundwater contamination sources. A. 805-806. Hence, Wolfs first argument is unavailing.

We also reject Wolfs contention that declaratory relief was inadequate. The entry of a declaratory judgment ensured Woll prompt reimbursement of reasonable response costs incurred in the future, while protecting Eaton and Fifth Street from an excess judgment in the event further response costs were not incurred. Thus, we agree with the Court’s grant of declaratory, rather than additional monetary, relief.

Woll next contends that its claim for tortious interference with contract— based on the failed sale of the site for $1.4 million, which was not completed due to discovery of the contamination — gives rise to damages under the STSPA. We disagree. The Pennsylvania Supreme Court has framed the damages recoverable under the STSPA as “clean up and diminution in property value.” Centolanza v. Lehigh Valley Dairies, Inc., 540 Pa. 398, 658 A.2d 336, 340 (1995). Centolanza instructs that the STSPA, a “remedial statute,” should be “liberally construed.” It allowed for the recovery of clean-up costs and property diminution, but did not indicate those damages were exclusive. Indeed, following Centolanza, lower Pennsylvania courts have also allowed for recovery of personal injury damages. See Wack v. Farmland Indus., Inc., 744 A.2d 265 (Pa.Super.Ct.1999); Bruni v. Exxon Corp., 52 Pa. D. & C.4th 484, 2001 WL 1809819 (Com.Pls.2001); see also Krebs v. United Refining Co. of Pa., 893 A.2d 776, 786 (Pa.Super.2006) (confirming that private plaintiffs can bring STSPA claims for cleanup, diminution in property value, and personal injury). Centolanza, however, made clear that the damages recoverable under the STSPA only reach as far as necessary to promote the goal of the Act— the prompt clean-up of spills. See id. Damages for diminution in property value, which typically approximate lost proceeds, serve this purpose and are already recoverable. The jury considered diminution in property value in determining its damages award. Duplicating this element of damages would produce a windfall, not promote prompt clean-up. We therefore reject this novel theory of damages.

Woll also levels four ancillary attacks on the District Court’s rulings. First, Woll contends that the Court improperly concluded that its common law claims were barred by the applicable statute of limitations. Although Woll filed its complaint after the statute of limitations expired, it insists that environmental contamination constitutes a “continuing trespass” that tolls the statutory period. Wolfs argument is foreclosed by precedents classifying soil and groundwater contamination as a permanent change rather than a continuing trespass. See Dombrowski v. Gould Electronics, Inc., 954 F.Supp. 1006, 1013 (M.D.Pa.1996) (“invasions such as water well contamination, waste, dumping, [and] soil contamination from underground storage tanks ... have all been said to have created a permanent change in the land so as to constitute a permanent trespass.”); Tri-County Business Campus Joint Venture v. Clow Corp., 792 F.Supp. 984, 996 (E.D.Pa.1992) (concluding that the depositing of hazardous waste, a “completed act at the time that the property was conveyed,” constitutes a permanent trespass); see also Sustrik v. Jones & Laughlin Steel Corp., 413 Pa. 324, 197 A.2d 44, 46 (1964) (treating actions “effecting] a permanent change in the condition of the land” as permanent trespasses). Thus, the District Court’s dismissal of these claims was proper.

Second, Woll contends that the District Court erred in rejecting a settlement agreement executed by Woll and Harold Bixler, the former secretary and treasurer of Eaton, which granted Bixler a release from suit in exchange for a monetary judgment against Eaton and the assignment of Eaton’s rights against its insurer. Woll contends that its contact with Bixler was permissible under the Pennsylvania Rules of Professional Conduct. However, Woll’s argument is not responsive to the two grounds on which the Court actually rejected the settlement agreement—that Bixler lacked actual, apparent, or implied authority to settle on behalf of Eaton, and that Bixler and Eaton possessed conflicting interests, which rendered the agreement unenforceable against Eaton. Finding the District Court’s conclusions reasonable, we decline to enforce the settlement agreement.

Third, Woll contends that the District Court erred in permitting Eaton’s expert, Mr. Heydt, to opine on the types of damages available under the STSPA. At the jury trial, Mr. Heydt testified that lost sales proceeds did not constitute a form of consequential damages recoverable under the STSPA. Woll contends that this testimony exceeded Mr. Heydt’s expertise as a forensic accountant. Even assuming that admission of the testimony was error, Woll does not identify any prejudice therefrom. Because Judge McLaughlin concluded that lost sales proceeds were not recoverable under the STSPA as a matter of law, Mr. Heydt’s testimony did not impact the jury determination. A new trial on this ground is thus unwarranted.

Fourth, Woll challenges the Court’s partial grant of attorneys’ fees. We lack jurisdiction to decide this issue because Woll did not appeal the Court’s order regarding fees, and the judgment appealed from did not implicitly or explicitly decide the issue. See White v. New Hampshire Dept. of Employment Security, 455 U.S. 445, 451 n. 13, 102 S.Ct. 1162, 71 L.Ed.2d 325 (1982) (“fee questions are not inherently or necessarily subsumed by a decision on the merits.”); see also Budinich v. Becton Dickinson and Co., 486 U.S. 196, 200, 108 S.Ct. 1717, 100 L.Ed.2d 178 (1988) (holding that a request for attorneys’ fees does not seek “reconsideration of matters properly encompassed in a decision on the merits” and is thus “collateral to” and “separate from the decision on the merits” (quoting White, 455 U.S. at 451-52, 102 S.Ct. 1162)); In re Colon, 941 F.2d 242, 245 (3d Cir.1991) (treating attorneys’ fees “apart from the merits for purposes of appeal”).

For the foregoing reasons, we will AFFIRM the order of the District Court. 
      
      . Settlements reached between Woll and other defendants totaling $370,000.00 exceeded Eaton and Fifth Street’s liability to Woll. Accordingly, although the Court awarded Woll damages, no funds were actually paid to Woll by Fifth Street and Eaton.
     
      
      . The District Court had jurisdiction over the CERCLA claims under 28 U.S.C. § 1331 and supplemental jurisdiction over the state law claims under 28 U.S.C. § 1367(a). We exercise jurisdiction over the judgment entered by the Court under 28 U.S.C. § 1291.
     
      
      . We review the District Court's construction of the STSPA de novo. Salve Regina College v. Russell, 499 U.S. 225, 231, 111 S.Ct. 1217, 113 L.Ed.2d 190 (1991) (applying de novo review to district court's determination of state law).
     
      
      . We reject Woll’s claim for natural resource damages under the HSCA on similar grounds. The District Court properly concluded that, absent an agency determination that Woll destroyed natural resources, these damages were too speculative to support monetary relief.
     
      
      . Woll also asks the Court to certify to the Pennsylvania Supreme Court the following issues: (1) whether the STSPA or the HSCA authorizes recovery of lost proceeds from the sale of real estate on the basis of tortious interference with contract; (2) whether the HSCA authorizes recovery of damages for property diminution and future clean-up costs; (3) whether the HSCA authorizes an award of attorneys’ fees; and (4) whether soil contamination constitutes a ''continuing trespass” for purposes of the statute of limitations. Each of these issues concerns settled law, does not control the outcome of the case, or does not present an issue of “substantial public importance” requiring “prompt and definitive resolution” by the Pennsylvania Supreme Court. See 210 Pa.Code § 63.10; 3d Cir. L.A.R. 110.1. Accordingly, Woll's request for certification is denied.
     
      
      . In its supplemental brief, Woll withdrew its argument that the dismissal of its CERCLA claims was error.
