MOVES3.0.4 is a patch to MOVES3. It is not considered a new model for state implementation plan (SIP) and transportation conformity regulatory purposes. Compared to MOVES3, MOVES3.0.4 does not substantially change onroad criteria pollutant emission rates at the County or Project Scale. Users should continue to follow the MOVES Technical Guidance that requires modelers at County and Project Scale to review and update the relevant I/M coverage inputs to reflect the latest I/M assumptions in regulatory analyses.

MOVES3.0.4 includes the following updates:

• For air quality modeling purposes, shifts speciation of onroad organic gases from an internal MOVES function to a post-processing task, similar to the process for nonroad speciation, and allows a similar workflow to be used for particulate matter (PM) without changing existing PM output (#44). Specifically:
  • We added two new pollutants to MOVES output: Total Organic Matter, which is the sum of organic carbon and PM organic matter, and Residual PM, which is all PM except for elemental carbon, sulfate particulate, and total organic matter.
  • We removed the option to output chemical mechanisms but added an option to include residual TOG (NonHAPTOG) in the MOVES output.
  • We added post-processing scripts to the MOVES “Tools” menu that associate MOVES onroad and nonroad emissions output with the appropriate speciation profiles.
  • For more information on chemical mechanisms and speciation in general, please see the MOVES technical reports, Speciation of Total Organic Gas and Particulate Matter Emissions from Onroad Vehicles in MOVES3 and Speciation Profiles and Toxic Emission Factors for Nonroad Engines in MOVES3.
• Changes vehicle inspection and maintenance (I/M) program data in the MOVES national defaults (#51).
  • Due to the ending of I/M programs in Tennessee, beginning in the 2023 analysis year, there are no longer default I/M program data for any county in Tennessee. Additionally, default I/M program data for Cache County, Utah, has now been included in the MOVES default database to reflect this existing program, and default I/M program data has been removed for Montgomery County, Ohio. Additional information for some specific I/M programs has been changed based on data submitted for the 2020 National Emissions Inventory.
  • For more information on I/M in MOVES, see the MOVES technical report, Emission Adjustments for Temperature, Humidity, Air Conditioning, and Inspection and Maintenance for Onroad Vehicles in MOVES3.
• Adds an error check to prevent missing values in the County table of county databases (CDBs). In earlier versions, it was possible to bypass the County Database Manager and import a table with missing values for countyTypeID, which could lead to incorrect off-network idle emissions (#47).
• Contains updated versions of the Java Runtime Environment (JRE) and Ant to avoid security concerns with earlier versions of these two programs (#46).
• Provides additional information for advanced users who want to compile the MOVES Nonroad code.
• Old moveslog.txt files are archived into moveslog.zip instead of getting deleted (#52).
