Appendix-1 February 27, 2008 

APPENDIX 

Revisions to Appendix A of the State Strategy for California’s 2007 State 

Implementation Plan.

Listed in the tables that follow are updates to the on-road emission inventories 

that were contained in Appendix A to the State Strategy that was released on 

May 7, 2007. These revisions reflect the latest transportation activity data that 

was submitted by the Southern California Association of Governments and the 

Kern County Association of Governments in January 2008. Also in each table 

are the revised baseline adjustments. These baseline adjustments are applied to 

the on-road emissions inventory to reflect the reductions of measures that have 

been adopted but not included in EMFAC2007, the on-road emissions model. 

Note that there are no revisions for the Coachella Valley. 

REVISIONS TO JANUARY 29, 2008 RELEASE 

After these plans were posted on January 29, 2008, ARB staff discovered that 

some of the input data used by the on-road emissions estimation model, EMFAC, 

had been corrupted. This resulted in errors in emissions calculations affecting 

the inventories and transportation conformity budgets for Antelope Valley – 

Western Mojave Desert and Eastern Kern County. The table entries for these 

areas on the following pages reflect the corrected numbers.
