Analysis  Type  Source  Type  Parameter  Data Source  Description  (including, boilers, heaters, emergency generators, etc.). Requires  knowledge of the computer model. AEDT 2b and subsequent versions  will replace EDMS and will be available at the following website:  http://aedt.faa.gov/  Until replacement by AEDT 2b, EDMS is available from the FAA at the  following website:  http://www.faa.gov/about/office_org/headquarters_offices/apl/research/m  odels/edms_model/.  Ground  Access  Vehicles  Traffic Data  Relevant Airport  Traffic Study  If available, most recent airport traffic study that includes traffic  volumes, speeds, mileage, ridership, and vehicle mix data is the most  optimal source.  Vehicle-miles- travelled  (VMT)  Automatic Vehicle  Identification  (AVI)  This system identifies, monitors, tracks, and collects data on vehicle  movements, enabling better management of a variety of airside and  landside vehicle activities. This information may be limited as not all  airports have this tracking system in place.  Emission  Factors  (On-Road)  MOVES  Although a full range of default data is available in MOVES, the  allocation of the default data down to the county level is based on a  generalized algorithm and is not the most recent nor best available local  data. Requires knowledge of the computer model. Model is available  from the EPA at the following website:  http://www.epa.gov/otaq/models/moves/index.htm  EMFAC  EMFAC is California’s model for estimating emissions from on-road  vehicles operating in California. EMFAC was issued by CARB but is  also EPA-approved. The model is available from the CARB at the  following website: http://www.arb.ca.gov/msei/modeling.htm.  Emission  Factors  (Off-Road)  NONROAD  Requires knowledge of the computer model. Model is available from the  EPA at the following website: http://www.epa.gov/otaq/nonrdmdl.htm.  106$_{ }$ APPENDIX F$_{ }$
