See More Frequent Questions about MOVES and Related Models. Although gallons of fuel consumed are not reported by MOVES, the factors used to convert total energy consumption (a MOVES reporting option) to gallons of fuel are contained in the FuelSubtype table (energy content, reported in kilojoules per gram of fuel)…
See More Frequent Questions about MOVES and Related Models. This problem usually occurs when the run specification does not include all possible vehicle and fuel types. MOVES internally allocates the input VMT to each of the source types and fuel types and only reports the VMT for the fuel types…
See More Frequent Questions about MOVES and Related Models. Very long run times are not unusual for Nonroad emission factor post-processing scripts, particularly with a large output database. To reduce script run time, we recommend doing the following: Reduce the size of your output database by choosing just the amount…
See More Frequent Questions about MOVES and Related Models. The RegionCounty table in the MOVES default database maps each county to a MOVES fuel region (defined by regionCodeID). If you are conducting a County or Project Scale Run, you do not need to modify this table to use alternate fuel…

Several toxic substances are listed as regulated substances under 40 CFR §68.130 with concentration qualifiers (e.g., "conc 37% or greater"). What does this concentration mean? When determining whether a threshold amount of these substances exists in a process, should I consider the weight of the entire solution, or simply the…
There is no qualifier attached to the listing for chlorine (40 CFR §68.130). The listing, therefore, applies to chlorine (CAS number 7782-50-5), regardless of physical state.
How did the January 6, 1998, final rule (63 FR 640) affect the definition of stationary source, as it relates to the transportation exemption?
