When an application is supplemental to or revises or amends in
immaterial respects an application for which the Department of Labor has
already certified that fair and equitable arrangements have been made to
protect the
interests of mass transit employees affected by the subject project the
Department of Labor will on its own initiative apply to the supplemental
or other amendatory application the same terms and conditions as were
certified for the subject project as originally constituted. The
Department of Labor's processing of these applications will be
expedited.
