EPA applied a number of control measures to the 2020 projected mobile
source emission inventory to estimate potential emission reductions from
mobile sources to meet the alternative ozone standard.  The mobile
source control measures includes some that were applied nationwide and
others that were applied only to local areas associated with counties
projected to exceed the alternative standard.  Information on the mobile
source control measures is contained in 2 files:

“National Level Mobile Source Control Measures.mdb” and “Local
Level Mobile Source Control Measures.mdb”

Information on the reductions associated with application of these
controls is contained in the file:

“070N Annualized Reductions.mdb”

Because of the large size of these files, they are stored on 2 CD’s in
the O3 RIA docket.
