Lydia,

Per the request from OMB staff, attached is a powerpoint file that
contains the year by year plots for monitors in the LA, Phildadelphia,
and St. Louis urban areas that Mike Rizzo has put together.  These are
the 3 areas that Mike included in his technical memo to the docket on
rollback.  I do want to point out that the three areas were selected to
represent urban areas where the was a lot of rollback required (LA), a
moderate degree of rollback (Phil), and relatively little rollback (St.
Louis) for just meeting the current standard.  I spoke to Mike this
afternoon and these are ready to be transmitted to OMB.
