  • What work still needs to be done at the derailment site?

    Although contaminated soil has been excavated and removed from the derailment site, some additional work remains. Soil sampling continues to check all areas where cleanup operations took place. Stream assessments continue, and culvert clean out has started. Groundwater and drinking water sampling also continues. Expect these investigations and possible additional…

  • Does MOVES Incorporate Anticipated Improvements in VOC Emission Factors Resulting from Improved Fuel Economy?

    See More Frequent Questions about MOVES and Related Models . Changes in fuel consumption affect VOC emissions by reducing refueling vapor losses and spillage. Other emissions (such as sulfates) are also affected by fuel consumption. MOVES incorporates changes due to fuel economy requirements that were finalized as of the date…

  • Can I use MOVES to Model Emissions from Vehicles in other Countries?

    See More Frequent Questions about MOVES and Related Models . The MOVES model was designed specifically to model the emissions from vehicles and equipment designed to meet emission standards in the United States. There are considerable challenges to adapting the MOVES framework to other nations, primarily around the need for…

  • What are the features available on the MOVES “Advanced Features” panel, and when would I use them?

    The MOVES graphical user interface (GUI) includes a panel for “Advanced Features,” which allows modelers to edit RunSpec inputs for preaggregation options and select input databases created by MOVES tools. The panel also includes some options that are obsolete or intended only for MOVES testing and development work. Each of…

  • Can I model emissions from Electric, Fuel-Cell, and Hybrid Vehicles and Equipment in MOVES?

    See More Frequent Questions about MOVES and Related Models . Electric vehicles and equipment do not generate tailpipe or evaporative emissions like conventional vehicles. However, these vehicles do consume energy, leading to greenhouse gas emissions, and they generate brake and tire particulate matter (PM) emissions. MOVES includes electricity as a…

  • Is MOVES the best tool for my work?

    See More Frequent Questions about MOVES and Related Models . EPA’s MOtor Vehicle Emission Simulator (MOVES) is a state-of-the-science emission modeling system that estimates emissions for U.S. mobile sources at the national, county, and project level for criteria air pollutants, greenhouse gases, and air toxics. States other than California must…
