Abstract

The EPA is developing a national nonroad air emissions inventory model called NONROAD. The latest version of this model is draft NONROAD2004. The model uses estimates of annual activity for each equipment type, generally expressed in terms of hours of operation or gallons of fuel used per year, to calculate yearly emission inventories. It will also calculate inventories on a seasonal (i.e., summer, fall, winter, spring), monthly, or daily (i.e., weekday or weekend day) basis by allocating annual activity to these smaller time periods. This memorandum documents the daily activity allocation fractions used in the current, draft version of NONROAD. The fractions are expressed as weekday and weekend day fractions of weekly activity and are provided for each equipment/category type. Seasonal and monthly activity allocation fractions are addressed in a separate technical memorandum (Report No. NR-004b).
