CA_Mobile Contribution.xls   contains the cost summary of extrapolated costs with CA mobile source rules reductions.

Ext Cost Tables.xls contains extrapolated cost calculations for glide path and no glide path sceanrios for alternate levels of the ozone standard (0.065 ppm, 0.070 ppm, and 0.075 ppm) including mobile source rule reductions in CA (these reductions are achieved at zero cost due to post 2020 implementation of these rules).  

Counts of CPTON by State 070 Entire Country Totals.xls   contains the distribution of cost per ton for East, West, and CA stratified in increments of 1,000.  

Slopes and Data of MC by Region.xls  contains data for regression equations to obtain the slopes of the marginal cost curves.
