Diсo, Inc., appeals from the District Court’s decision to grant summary judgment to the United States on the government’s claim to recover from Dico response costs incurred in association with the environmental cleanup of groundwater determined by the Environmental Protection Agency (EPA) to be contaminated. Dico also appeals the order dismissing its counterclaim, in which the company sought reimbursement of amounts it expended cleaning up the site. We affirm in part and vacate and remand in part.
I.
This case arises under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), 42 U.S.C. § 9601-9675, as amended by the Superfund Amendments and Reauthorization Act of 1986 (SARA), Pub.L. No. 99-499, 100 Stat. 1613. Under CERCLA, the EPA has broad “authority to direct clean-up operations prior to a final judicial determination of the rights and liabilities of the parties affected.”
Solid State Circuits, Inc.v. United States EPA,
This is not the first time this litigation has been before our Court.
See Dico, Inc. v. Diamond,
The following summer, in July 1988, Dico sought from the Superfund reimbursement for costs the company had incurred, and would continue to incur, with respect to its remediation efforts at the site. The EPA denied the petition, holding that the 1986 SARA amendment that permitted such reimbursement did not apply retroactively to the EPA’s cleanup order issued to Dico before the effective date of the amendment. The Environmental Appeals Board (EAB) sustainеd the EPA after an administrative hearing. Dico then brought suit in the district court, but the court granted summary judgment for the EPA, deferring to the agency’s interpretation of the statute. Dico appealed. We reversed and remanded to the district court with instructions to remand for further proceedings. Our opinion was filed in September 1994. On April 21, 1995, with Dico’s administrative claim for reimbursement pending before the EAB, the United States filed this action in the District Court seeking recovery from Dico — and only Diсo — of costs that the EPA had incurred in connection with cleanup of the groundwater at the Des Moines site. Dico filed a counterclaim for reimbursement of its costs, and also moved the EAB to stay the administrative proceedings on the ground that the claim pending before the EAB was the same as Dico’s counterclaim filed in federal court. The EAB granted the motion.
On September 13,1996, the District Court granted the EPA’s motion to dismiss Dico’s counterclaim for failure to exhaust administrative remedies. On April 1,1997, the court granted summary judgment to the EPA on its claim for response costs, including indirect and oversight costs, in the amount of $4,378,110.66.
See United States v. Dico, Inc.,
II.
We first address Dico’s claim that the court erred in dismissing its counterclaim. The District Court held that Dico failed to exhaust its administrative remedies. In the absence of exhaustion, when exhaustion is required, the court does not have subject matter jurisdiction. We review this question of law de novo.
In its counterclaim, Dico sought recoupment of its remediation costs, arguing that its operations did not cause TCE contamination of the groundwater at the site. Dico says it seeks only an offset of the EPA’s claim for response сosts, which are less than Dico’s costs, and no affirmative recovery— notwithstanding its claim that it is liable for no cleanup costs whatsoever, a theme that runs throughout its brief. Dico does not contend that there is no exhaustion requirement, but makes various arguments that the requirement should be “waived” in these circumstances,. that somehow Dico did exhaust its administrative remedies, or that Dico was “excused” from exhausting. We are not persuaded by any of these arguments, as the law is very clear on this issue in circumstances such as these.
“The doctrine of exhaustion of administrative remedies is one among related doctrines — including abstention, finality, and ripeness — that govern the timing of federal-court decisionmaking.”
McCarthy v. Madigan,
No later than sixty days after completing the response and remedial action rеquired by an administrative order, a party may “petition the President for reimbursement from the Fund for the reasonable costs of such action, plus interest.” 42 U.S.C. § 9606(b)(2)(A). Then, “[i]f the President refuses to grant all or part of a petition made under this paragraph, the petitioner may ... file an action against the President in the appropriate United States district court seeking reimbursement from the Fund.”
Id.
§ 9606(b)(2)(B). Using such language, Congress fully intended that petitioners seeking reimbursement of costs expended complying with an administrative cleanup order should not have a cause of action in the courts until they have exhausted the administrative remedies set forth in the statute.
See United States v. M/V Santa Clara I,
Dico’s claim that the requirement should be “waived” is without merit. It is true that “where Congress has not. clearly required exhaustion, sound judicial discretion governs.”
McCarthy,
To the extent an exhaustion requirement is judicially imposed, -it can be waived. The waiver decision should “be guided by the policies underlying” the doctrine of exhaustion of administrative remedies.
Bowen v. City of New York,
This ease has little to commend it for waiver. Here, a fully-developed factual record drawing upon agency expertise likely would be most helpful to the court.
Cf. Bowen,
476. U.S. at 485,
Dico also argues that it exhausted its administrative remedies because it filed its administrative petition for reimbursement before the EPA filed its lawsuit in the District Court. The company makes this argument notwithstanding the fact that Dico, and not the government, sought to stay the administrative proceedings. Although Dico already had filed its administrative claim when the United States filed suit in federal court, the proceedings were not completed. The administrative remedies required by statute were not exhausted absent a final administrative decision.
Dico contends that it should be “excused” from exhausting its administrative remedies because it otherwise loses all recourse to the courts on its claim for reimbursement. “To be weighed against the interests in exhaustion is the harsh impact of the doctrine when it is invoked to bar any judicial review of a [petitioner’s] claims.”
McGee v. United States,
Under Federal Rule of Civil Procedure 13(a), a compulsory counterclaim must be asserted in responsive pleadings or it is “thereafter barred.”
Baker v. Gold Seal Liquors, Inc.,
In sum, the District Court properly dismissed Dico’s counterclaim. The court did not have subject matter jurisdiction because Dico failed to exhaust the administrative remedies provided by CERCLA before filing its counterclaim. But the counterclaim was not compulsory and therefore should have been dismissed without prejudice.
*578 We now consider the District Court’s decision to grant summary judgment to the United States on the merits of its сlaim.
III.
Dico presents a series of questions raising the issue whether, and if so to what extent, Dico was liable for the groundwater contamination for which the administrative cleanup order was issued. The District Court, in granting summary judgment for the United States on its claim for reimbursement of costs associated with cleanup of OU-1, concluded that Dico raised no genuine issues of material fact in response to the EPA’s motion. We review de novo, viewing the evidence in the light most favorable to Dico, and we will affirm only if we agree there are no genuine issues of material fact and.that the United States is entitled to judgment as a matter of law.
Dico first argues that the EPA has not proved that the company should be held strictly hable for the EPA’s costs of cleaning up OU-1 under 42 U.S.C. § 9607(a).
See Control Data Corp. v. S.C.S.C.
Corp.,
Although Dico may have conceded that its operations over the years could have caused soil contamination at the site, we see nothing in the record to support the proposition that Dico admitted that any such soil contamination caused the groundwater contamination at OU-1, which in turn caused the EPA to incur response costs. In fact, as wе read the record, Dico consistently has denied responsibility for groundwater contamination at OU-1, even while conceding the possibility that it is liable for soil contamination within the site. As the United States acknowledges,-
Operable Unit 1 (“OU-1”), which is the focus of this litigation, was separately delineated to deal with the groundwater contamination, and Operable Unit 2 (“OU-2”), also known as the South Area Source Control Operable Unit, was designated to address releases tо the groundwater from the soil at Dico’s property — which comprises a portion of the Site.
Brief of Appellee at 6 (emphasis added). The government freely admits that “[t]he EPA in this lawsuit is seeking only to recover its expenses regarding OU-1, and not OU-2.” Id. at 6 n. 7 (emphasis added). Any response costs the EPA might have incurred in relation to OU-2 or any other operable unit within the site, and therefore evidence of Dico’s alleged admissions regarding soil contamination within the site, are of no consequence.
It remains to be determined whether Dico has raised a genuinе issue of material fact on the question of whether the TCE disposal for which Dico is potentially responsible, soil contamination within the site, is the source of the groundwater contamination at OU-1. Because the District Court determined that Dico admitted liability for some of the EPA’s OU-1 response costs (which we now hold was error), the court did not address the question. After reviewing the record before us, we conclude that Dico has carried its burden *579 and that summary judgment was inappropriate in this case.
There is some evidence in the record that the highest concentrations of TCE groundwater contamination are directly beneath Dico’s property. This certainly is circumstantial evidence that it was Dico’s actions that caused the contamination at OU-1. But Dico submitted evidence that none of the EPA’s numerous soil borings from the area establishes a continuous line of contamination from the soil surface, through fill and native soils, to the groundwater. Further, Dico asserts and has submitted evidence in support of the assertion that, to the extent the record may be said to include evidence of continuous borings that do show a direct line from Dico property to the water table, the methodology employed in the sampling and the testing of those borings is open to serious challenge. The EPA answers that there are other ways for the TCE contamination to have migrated to the groundwater other than straight down through the soil. But the EPA’s hypothesis that this may be what happened at the Des Moines TCE Site is unsupported by record evidence, and therefore does not resolve the fact question of whether that is what actually happened at the site in the years before groundwater contamination was discovered.
Granted, the witnesses whose testimony arguably establishes genuine issues of material fact have self-serving reasons for testifying as they have. But that also can be said of the EPA’s witnesses. Assessing the credibility of witnesses and evaluating the weight to assign to their testimony is the job of the fact-finder, and is not a function for the court on a motion for summary judgment.
See Oldham v. West,
We conclude that the United States, as plaintiff seeking a monetary recovery of considerable magnitude, should be put to its proof on its claim that Dico’s disposal of hazardous materials caused groundwater contamination that led to the response costs that the EPA incurred in connection with OU-1. Dico’s evidence raises a genuine issue of material fact for resolution at trial.
Finally, Dico contends that it was entitled to the statutory defense set forth in 42 U.S.C. § 9607(b)(3) (1994) because the release of hazardous substances at issue and the resultant damages “were caused solely by ... an act or omission of a third party” not connected with Dico. The company argues that, with regard to costs related to the so-called north plume of contamination at the site, located north of and up-gradient from Dico’s property, “Dico is an innocent third party” because that “contamination was caused solely by sources other than Dico.” Brief of Appellant at 29. Dico reiterates that it is not responsible for the groundwater contamination “at all.” Id. But even if it is, Dico claims, “the North Plume is a separate and distinct plume whose harm is capable of reasonable divisibility and apportionment,” id. at 31, and as a matter of law Dico should not be responsible for that part of the EPA’s response costs that are not attributable to Dico releases.
Because we have held that the ease should be remanded for trial on the question of Dico’s liability, we need not and do not address this fact-dependent argument. It should be resolved at trial.
IV.
For its final issue on appeal, Dico insists that the indirect and oversight costs that the EPA supposedly incurred in connection with OU-1 were not recoverable. The District Court held that they were, although the court did not indicate what part of the $4.3 million award was attributable to the disputed costs (and counsel for the government could not definitively break it down for us at oral argument). Dico contends that such expenses are not “costs of removal or remedial аction incurred by the United States Government,” 42 U.S.C. § 9607(a)(4)(A), within the meaning of CERCLA. Because we are vacating the judgment entered for the United States and remanding for trial, the money judgment is necessarily set aside in its entirety. Resolution of the issue of whether costs that the EPA may recover pursuant to 42 U.S.C. § 9607(a) include indi *580 rect and oversight costs is reserved for another day, and quite possibly another case.
V.
The District Court’s decision to dismiss Dico’s counterclaim on the ground that Dieo has nоt exhausted its administrative remedies is affirmed, with instructions that the court make it clear that the dismissal is without prejudice. 4 The judgment entered for the United States is vacated and the money judgment is set aside. The ease is remanded to the District Court for further proceedings consistent with this opinion.
Notes
. The President has delegated much of his authority in these matters to the Administrator of the Environmental Protection Agency (EPA).
See Dico, Inc. v. Diamond,
. There is a fourth element that must be proved as well: “that the cоsts [sought to be recovered by the EPA] were necessary and consistent with the national contingency plan.”
Control Data Corp. v. S.C.S.C. Corp.,
. As we mentioned early in the opinion, after the District Court granted summary judgment to the United States in this case, the EPA moved the EAB for denial without a hearing of Dico's petition for reimbursement on grounds of res ju-dicata. Dico’s counsel told the Court at oral argument that the motion has been granted. Although we dо not know the grounds on which the EAB’s decision was made, and we therefore express no opinion on the merits thereof, we do point out that it is Dico’s counterclaim, not the government’s claim, that is said to be identical to the administrative petition for reimbursement. It should be remembered that the counterclaim was dismissed on jurisdictional grounds, and there was no full and fair adjudication on the merits. Moreover, given our disposition of the present appeal, there is no final judgment from the District Court on the government’s claim.
