ORDER

1
We dismiss this appeal as moot and vacate the judgment of the district court.   We remand to the district court for further consideration in light of the recently adopted amendments to the State of California's prevailing wage regulations, 8 Cal.Code Regs. § 16000 et seq..  This court expresses no opinion on the validity of the new regulation.   The district court in any subsequent ruling should determine explicitly whether California's prevailing wage scheme for public works contractors, which no longer incorporates a requirement that the contractors meet their fringe benefits obligations on a "line-by-line" basis, see 8 Cal.Code Regs. § 16200(a)(3)(I) as amended, is preempted by the Employee Retirement Income Security Act of 1974, 29 U.S.C. § 1001 et seq..
