       This page lists substantive errors and concerns that have been identified for Draft MOVES2009.
Many of the items listed here are errors that we intend to fix for the final version of MOVES2009. Others
items are not errors, perse, but areas where the MOVES design may be problematic and not match user
expectations.

       If you find problems with MOVES that are not on this list, please let us know by emailing the MOVES
team at mobile@epa.gov .  We plan to update this list as needed. Thank you for helping us improve the
MOVES model.
Problem Reported
1 . Default vehicle miles traveled (VMT) projections may not
match the VMT projections used in other EPA models (such and the
National Mobile Inventory Model, NMEVI).

2. There will be no output of Benzene, Ethanol, MTBE,
Naphthalene or Methane for the Refueling Vapor or Refueling Spillage
loss processes, even though there are check boxes for these pollutants
in the Pollutants and Processes panel.

3 . When you execute MOVES, you get the pop-up window that
allows you to cancel. However, if you instead hit the X in the top
corner of the box, the program will execute. The normal response
should be to cancel the run.

4. There will be no output of Methane for Evaporative Vapor,
Evaporative Permeation or Evaporative Leak losses, even though there
are check boxes for these processes for Methane in the Pollutants and
Processes panel.

5. There are no options to get non-methane hydrocarbon, non-
methane organic gases, total organic gases or volatile organic
compound speciation of total gaseous hydrocarbons or options for
methane, nitrous oxide, benzene, ethanol, MTBE, naphthalene, 1,3-
butadiene, formaldehyde, acetaldehyde or acrolein for the crankcase
running, crankcase start or crankcase extended idle processes.

6. There are no options to get non-methane hydrocarbon, non-
methane organic gases, total organic gases or volatile organic
compound speciation of total gaseous hydrocarbons or options for
methane or nitrous oxide for the extended idle process.

7. The sulfate particulate (PM10 and PM2.5) results from the
Extended Idle Exhaust process are not correct. This will also cause the
Primary Exhaust Particulate Total results (PM10 and PM2.5) for this
process to be incorrect.

8. When using the Project Level scale, the Extended Idle Exhaust
process will only produce results for Total Energy Consumption.

9. When using the Project Level scale, adding grade to a link will
not work properly and incorrectly adjusts for the effects of grade. Do
not use the grade option.

10. In the Time Spans panel, if you choose the Time Aggregation
Level Year, the panel will still allow you to choose Months, Days and
Hours. Of course, since you want a total year, selecting anything other
than all months, days and hours will cause problems. If you choose
the Time Aggregation Level Year, you must select all months, days
and hours. Similarly, if you choose the Time Aggregation Level
Month, you must select all days and hours. If you choose the Time
Aggregation Level Day, you must select all hours.

1 1 . When making a retrofit parameter file for importing for the On
Road Retrofit Strategies panel, you must not use the PollutantID,
ProcessID, FuelTypelD or SourceTypelD numbers. You must use the
text names for these parameters.

12. This version of MOVES does not include criteria pollutant or
air toxic emission factors for motorcycles. Composite fleet emission
rates of criteria pollutants or air toxics that are intended to include
motorcycle emissions will not properly reflect their contribution.

13. The Well-to-Pump emission process in this version of MOVES
has not been updated and will not produce appropriate emission
results. Users should not select Well-to-Pump process.

14. The emission results for non-methane hydrocarbon, non-
methane organic gases, total organic gases or volatile organic
compound speciation of total gaseous hydrocarbons from Refueling
Vapor and Refueling Spillage losses are not correct. Do not select
these pollutants when including refueling emissions.

1 5 . The option to Manage Input Datasets or the Pre-Processing
Data Importer option does not work properly in some circumstances.
We are scoping the problem.

16. The Calculation Type of Emission Rates on the Scale panel
will produce emission rates only for the Exhaust Running process.

17. If you select only the brake wear and tire wear toggle boxes for
PM, the Distance Traveled toggle box will be inaccessible. You will
need to select another pollutant in the Running process in order to
obtain vehicle miles traveled information along with brake wear and
tire wear emissions.

18. I/M NOx rates for the HD RegClassIDs (41, 42, 46, 47, & 48)
for model years 2010 and later are greater than the non-I/M rates.

19. When using the Custom Domain option of the County Data
Manager, you can not obtain emissions for the Refueling
Displacement Vapor Loss or Refueling Spillage Loss emission
processes.

20. Introducing electric vehicles into your fleet using the
Alternative Vehicle Fuel & Technology option of the Strategies
navigation panel inappropriately reduces Tirewear and Brakewear PM
emissions proportional to the number of electric vehicles.

21 . When using the Emission Rate calculation in the Scale panel,
you cannot obtain either elemental carbon (EC) or organic carbon
(OC) results.

22. The Source Classification Code (SCC) option in the Emission
Output Detail navigation panel inappropriately diverts some emissions
from diesel fueled vehicles into gasoline-only SCCs. This will make
both the gasoline and diesel results using the SCC codes inaccurate.

23. Rates for Heavy Duty Diesel Running NOx emissions in model
years 2021 onward are too high. Running MOVES for heavy duty
diesel vehicles after year 2020 will cause inaccurate emissions for
those model years.

24. There is an error in the MOVES Output Processing Scripts.
Once a RunSpec is loaded into the MOVES GUI, the scripts may be
found in the Post Processing dropdown menu. The TabbedOutput.sql
script has the error. A new version of the script may be found at
www.epa.sov/otaq/models/moves/. Download this script and use it to

replace the following file:

25. If the Pollutants/Processes panel is the active panel and the user
opens a RunSpec from disk (using File-Open) or creates a new
RunSpec (with File-New), the panel will become unresponsive after
the RunSpec is created. If this happens, resize the main MOVES
window to get the frozen panel to respond (or simply change to a
different panel).

26. Draft MOVES2009 erroneously applies a humidity correction
to pollutants that do not need a humidity correction. The model also
neglects to apply a NOx humidity correction for E85 vehicles. These
errors can cause an error in emissions of about 10 percent.
