Heading: Striking Plaintiff's Expert Affidavit

Text: 31 Plaintiffs argue that the district court erred in striking their affidavit from Barry Sulkin, an expert on TMDLs. The affidavit set forth Sulkin's opinion that none of the TMDLs submitted by Oklahoma met all the statutory and regulatory requirements for TMDLs. As the district court noted and Plaintiffs conceded at oral argument, Plaintiffs failed to raise this in their objections to the magistrate judge's report. They therefore have waived the issue. Talley v. Hesse, 91 F.3d 1411, 1412 (10th Cir. 1996). When Plaintiffs were informed about waiver, as in this case, we enforce the waiver unless the ends of justice dictate otherwise. Id. at 1413. For the reasons given above, Sulkin's affidavit, which is about the substantive adequacy of the TMDLs approved by the EPA, is beyond the scope of the legal issues in this case. We see no reason to think the ends of justice are implicated by the court's striking this affidavit and therefore deem the issue waived.
