Heading: The Restricted Experiments

Text: We do not reach the issue of whether the DOE's decision not to include information about restricted experiments in the FREA was arbitrary or capricious because the district court properly found that this argument was waived. Here, Tri-Valley CAREs did not address the district court's ruling that the argument was deemed waived in its opening appellate brief. Thus, the issue is not properly before us. See Smith v. Marsh, 194 F.3d 1045, 1052 (9th Cir.1999) (holding that arguments not raised by a party in its opening brief are deemed waived). Claims not made in an opening brief in a sufficient manner to put the opposing party on notice are deemed waived. Swierkiewicz v. Sorema, N.A., 534 U.S. 506, 512, 122 S.Ct. 992, 152 L.Ed.2d 1 (2002) (holding that claims must put parties on sufficient notice of underlying arguments, or arguments are deemed waived).
