Heading: Preemptive Preservation of Issues

Text: 148 UWAG has purported to preserve the right to raise new challenges to the Phase II Rule if we remand significant aspects of it to the EPA because UWAG views the Rule as an integrated whole. If certain aspects of the Rule are remanded, UWAG suggests, previously unobjectionable provisions may become, in its view, unacceptable. We are not sure what challenges UWAG seeks to preserve. Of course, UWAG will have the right to challenge any rule the EPA may promulgate on remand through a new petition for review. See 33 U.S.C. § 1369(b). Insofar as UWAG seeks to raise further challenges following the issuance of our ruling but before the EPA acts on remand, however, it waived those challenges by failing to raise them in the briefs it has already submitted to this Court. See Norton v. Sam's Club, 145 F.3d 114, 117 (2d Cir.1998) (noting that issues not argued in a party's briefs are considered waived). We thus reject UWAG's claim to have preserved the right to raise new challenges to the Rule currently before us on this petition for review.
