APPENDIX E$_{ }$ data is needed for all scenarios (i.e., Build and No-Build) and analysis year(s). A “Traffic Impact  Analysis” of the project study area is the best source for this information.  The two EPA-approved on-road vehicle emissions’ models for quantitative CO and PM hot-spot  analyses are MOVES and  California’s EMFAC. Information pertaining to these models summarized in  Table E-4  ( EPA-Approved On-Road Emissions Models for Quantitative CO and  PM Hot-Spot Analyses ) below as well as detailed in  Section 5  ( Air Quality Assessment Models )  of the  Handbook . Furthermore, the steps for using MOVES and California’s EMFAC to generate  emission factors necessary to complete project-level CO and PM hot-spot analyses are discussed  in this section and illustrated in  Figures E-1  through  E-3 .  MOVES requires multiple inputs (e.g., vehicle population, vehicle age distribution, vehicle miles  travelled [VMT], etc.) and depending on the geographical scale (i.e., national, county, or local)  of the project, default values may not be appropriate to use. Thus state and regional air quality  regulatory and transportation planning agencies should be consulted  to request the most recent  MOVES inputs of the project’s geographical area.  Figure E-1  ( Steps for Using MOVES in  Project-Level CO Analysis )  illustrates the steps for using MOVES in a project- level CO  analysis).  In 1997, EPA approved the  CO Protocol 97  for use as an alternative hot-spot analysis method in  California. This protocol is strongly recommended for CO hot -spot analysis in California;  97  California DOT,  Transportation Project-Level Carbon Monoxide Protocol (CO Protocol),  http://www.dot.ca.gov/hq/env/air/pages/coprot.htm.  92$_{ }$ E.2.4.1  CO Emissions Modeling  Source: EPA’s website at http://www.epa.gov/otaq/stateresources/transconf/projectlevel-hotspot.htm and  http://www.epa.gov/otaq/models/moves/index.htm as well as CARB’s website at http://www.arb.ca.gov/msei/modeling.htm  for latest updates and model revisions.
