Plaintiff, Dr. Avery Jones, appeals the District Court’s order refusing to consider his claims for injunctive relief, costs, and attorney and expert witness fees even though the jury (1) found that defendant City of St. Clair, Missouri (City) had violated the Federal Water Pollution Prеvention and Control Act, 33 U.S.C.A. § 1251 et seq. (West 1986) (Clean Water Act), and (2) awarded Jones $15,000 on his common law nuisance claim. The City cross-appeals, asserting there was insufficient evidence to justify submission of this case to the jury on either count. We affirm the judgment entered on the jury verdicts, but remand the case with directions that the District Court consider the merits of Jones’s motion for injunctive relief and that it exercise its discretion with regard to Jones’s post-trial motion for costs and attorney and expert witness fees.
Jones brought suit against the City, alleging that failure of the City’s waste disposal system caused a waste treatment lagoon to overflow into a lake located on Jones’s property and was responsible for the eutrophication of the lake, for a fish-kill that depleted the fishing stock, and for damage to the Merimac River, into which water from Jones’s lake eventually flows. Count I of the complaint alleged a violation of the Clean Water Act and sought injunctive relief, civil penalties, costs, and attorney fees, as authorized under the terms of the Act. 33 U.S.C.A. § 1365 (West 1986). Count II alleged a state law claim based on the theory of common law nuisance and sought damages, injunctive relief, and costs. At Jones’s insistence, and without objection by the City, both counts were submitted to the jury. The jury found that the City was in violation of the Clean Water Act. In addition, the jury found for Jones on his common law nuisance claim and awarded him dаmages of $15,000. Following this verdict, Jones moved for injunctive relief under § 1365(a) of the Clean Water Act and under a common law nuisance theory, and for an award of costs and attorney and expert witness fees under § 1365(d) of the Clean Watеr Act. The District Court denied the motion, ruling that submission of the Clean Water Act claim to the jury barred Jones from recovering his costs or fees. Similarly, in denying injunctive relief, the Court ruled that the request for injunctive relief was barred because of Jones’s insistence on submission of the entire case to the jury. Appendix (App.) at 100, 101. 1
Turning first to the cross-appeal, the City contends that insufficient evidence was presented to allow this case to go to the jury. The City did not raise this issue during trial, еither in a motion for directed verdict or in a motion for judgment notwithstanding the verdict. Insufficiency of the evidence was first raised by the City in a motion for new trial following entry of the District Court’s judgment. This Court has repeatedly held that when the moving party hаs not made a motion for directed verdict or a motion j.n.o.v., “ ‘[w]e cannot test the sufficiency of the evidence to support the jury’s verdict beyond application of the “plain error” doctrine in order to prevent a manifest miscarriage of justice.’ ”
Shell v. Missouri Pacific R.R.,
At trial, plaintiffs’ counsel did not move for a directed verdict or for judgment notwithstanding the verdict. Under such circumstances, we are generally powerless to review the sufficiency of the evidencе except for plain error. However, plaintiffs’ counsel did file a motion for a new trial on grounds of insufficiency of the evidence. The motion was denied and plaintiffs assigned this denial as error in their notice of appeаl. This affords us an opportunity to determine whether the district court abused its discretion in denying the motion for new trial on the grounds of insufficient evidence.
Id. at 529-30 (citations omitted.)
In a footnote, the Court explained its holding, stating, “We are not technically reviewing thе sufficiency of the evidence. Rather, we are reviewing whether the district judge has abused his judicial discretion in denying a new trial or whether as a matter of law the denial of a new trial was erroneous because there was an ‘аbsolute absence of evidence to support the jury’s verdict.’ ”
Id.
at 530 n. 1 (quoting
Urti v. Transport Commercial Corp.,
Jones’s appeal raises the issue of whether submission of the Clean Water Act and nuisance claims to the jury precludes him, after he has obtained a jury verdict in his favor on both claims, from obtaining a ruling by the District Court on the merits of his request for injunctive relief. The City first argues that during a trial conference, Jones specifically waived his right to seek injunctive relief under the Clean Water Act and therеfore is barred from seeking such relief. We find this argument meritless. The District Court did not purport to find a waiver, and after a careful review of the record, including those portions that the City particularly has called to our attention, we find nоthing from which we could conclude that Jones waived his claim for injunctive relief.
In a second attempt to bar Jones’s request for injunctive relief under the Clean Water Act, the City cites
United States v. Ferro Corp.,
The narrow question that is before us is whether submission of Jones’s сase to the jury, without objection by the City, should result in the automatic denial of Jones’s request for injunctive relief. We think it should not. All that the jury was asked to do with respect to Jones’s Clean Water Act claim was to decide whether the City had viоlated the Act. The jury was not asked to decide the relief, if any, that Jones should have in the event a violation was found. Since the relief available under the Act is equitable in nature,

and the injunctive relief sought under the common law nuisance claim also sounds in equity, the power to grant or deny that relief clearly resides in the trial judge.
See Weinberger v. Romero-Barcelo,
Jones also appeals the summary denial by the District Court of his motion for costs and attorney and expert witness fees. The Clean Water Act leaves the awarding of costs and fees to the discretion of the court. Section 1365(d) of the Act states, “The court, in issuing any final order in any action brought pursuant to this section, may award costs of litigation (including reasonable attorney and expert witness fees) to any party, whenever the court determines such awаrd is appropriate.” The statute plainly vests the trial court with broad discretion. We believe, however, that upon a proper motion for costs and fees, the trial court has a duty to exercise that discretion. Moreоver, the responsibility to decide this matter rests solely with *482 the trial judge. It cannot be shifted to the jury by submission to the jury of the basic question of whether the defendant has violated the Clean Water Act. We therefore remand this case to the Distriсt Court and direct the court to consider and exercise its discretion with regard to Jones’s motion for costs and attorney and expert witness fees under § 1365(d). In so doing, we express no view as to whether the court should award costs and fеes. We merely direct the court to exercise its discretion.
We affirm the judgment of the District Court entered upon the jury verdicts in favor of Jones. We remand the case to the District Court for further proceedings consistent with this opinion insоfar as Jones’s requests for injunctive relief, costs, and attorney and expert witness fees are concerned.
Notes
. The Order stated, "Plaintiff in the instant case elected to submit the issue of liability under the Act to the jury, which rendered a judgment of liаbility without imposing penalties or costs. The Court will not reopen the judgment to award plaintiff the costs of obtaining $15,000 private damages for nuisance.” App. at 101. With regard to the request for injunctive relief, the District Court made a similar determination, stating, "The Court will not now reopen the judgment to entertain what is essentially a new cause of action for injunctive relief.” Id.

the court held that "there is no right to a trial by jury in an action brought by the United States pursuant to the Clean Water Act." 23 E.R.C. at 2054. The Fourth and Eleventh Circuits have held that suits for civil penalties under the Clean Water Act are equitable in nature and do not implicate the Seventh Amendment right to a jury trial.

. 33 U.S.C. § 1365(a) states, in part, "The district courts shall have jurisdiction, without rеgard to the amount in controversy or the citizenship of the parties, to enforce such an effluent standard or limitation, or such an order [issued by the Administrator or a state with respect to such a standard or limitation], or to order the Administrator to perform such act or duty, as the case may be, and to apply any appropriate civil penalties under section 1319(d) of this title.”
The Supreme Court has interpreted the Clean Water Act as leaving broad equitable discretion with the trial judge.
