Official Release of the MOVES5 Motor Vehicle Emissions Model for SIPs and Transportation Conformity
Agencies
ELI5 AI
The EPA has created a new tool called MOVES5 to help figure out how much pollution comes from vehicles like cars and buses. People who work with this tool have two years to start using it outside of California.
Summary AI
The Environmental Protection Agency (EPA) has released the MOVES5 model, which is used to estimate emissions from vehicles like cars, trucks, and buses. This model is crucial for creating state implementation plans (SIPs) and transportation conformity analyses, and it incorporates the latest data and regulations on emissions. While it must be used immediately in SIP development, there's a two-year grace period until December 2026 for it to become mandatory in transportation conformity analyses outside of California. The EPA provides guidance and support materials to help users transition to MOVES5, ensuring they can accurately assess vehicle emissions.
Abstract
The Environmental Protection Agency (EPA) is announcing the availability of the latest major release of the MOtor Vehicle Emission Simulator (MOVES) model, MOVES5, for official purposes outside of California. MOVES5 is the latest version of EPA's state-of-the science modeling tool for estimating emissions from cars, trucks, buses, and motorcycles based on the latest data and regulations. MOVES5 is available for use in state implementation plans (SIPs) and transportation conformity analyses outside of California. This notice starts a two-year grace period before MOVES5 will need to be used as the latest EPA emissions model for transportation conformity determinations outside of California, both in new regional emissions analyses and in new hot-spot analyses.

General Summary of the Document
The Environmental Protection Agency (EPA) has announced the release of the MOVES5 model, which is a critical tool for estimating vehicle emissions from various types of motor vehicles, including cars, trucks, and buses. This new model will play a significant role in forming state implementation plans (SIPs) and in conducting transportation conformity analyses, which are necessary for complying with national air quality standards. MOVES5 incorporates the latest data and regulatory updates to improve accuracy and efficiency in emissions estimation. While MOVES5 is to be used immediately for SIP development, a two-year grace period allows its adoption in transportation conformity analyses, expiring in December 2026. EPA is providing guidance and resources to facilitate the transition to this new model.
Significant Issues or Concerns
One of the main challenges presented by the document is its complexity and density, which might make it difficult for readers to quickly grasp the essential information. The use of technical and regulatory language throughout the document could be a barrier to understanding for individuals without a background in these areas. Additionally, the transition details between the different MOVES models and the specific requirements for SIPs and transportation conformity are not presented in an easily digestible format. Furthermore, the document does not address the potential costs or resources needed for state and local agencies to transition to MOVES5, nor does it highlight the challenges faced by regions that may lack the necessary resources for rapid implementation.
Public Impact
Broadly, the implementation of MOVES5 is an important step forward in ensuring that vehicle emission estimates are more accurate and in line with current regulations. This can positively impact public health by promoting cleaner air and aiding in compliance with air quality standards. For the general public, the changes may not be immediately noticeable, but they contribute to long-term improvements in environmental and public health.
Impact on Specific Stakeholders
State and local agencies involved in transportation planning and air quality management will be impacted by the introduction of MOVES5. These stakeholders will need to familiarize themselves with the new model and adjust their processes accordingly. While EPA offers support and guidance during the transition, these agencies may face significant challenges related to training and resource allocation. For areas that lack the infrastructure to quickly adopt MOVES5, the grace period provides some leeway, but they might still struggle to meet the new requirements effectively.
In summary, while the release of MOVES5 represents progress in vehicle emissions modeling, careful consideration of its implications, particularly for resource-constrained regions and agencies, is essential to ensure a smooth transition and the continued improvement of air quality standards nationwide.
Issues
• The document is lengthy and dense, which might make it difficult for some readers to understand the key points quickly. Simplification and summarization could enhance clarity.
• The notice introduces technical details about the MOVES5 model updates and requirements, which may not be clear to all potential users without additional explanation or simplified language.
• The document heavily uses regulatory language, which might be confusing for individuals without a legal or regulatory background.
• The transition details between MOVES models and the specific requirements for SIPs and transportation conformity could be clearer for state and local agencies.
• The document does not explicitly address potential costs or resource implications for state and local agencies in transitioning to MOVES5, which could be a concern.
• The grace period explanation, though detailed, could benefit from simplified language to enhance understanding for a broader audience.
• Guidance on how model users should update inputs from previous MOVES versions might not be sufficient for users unfamiliar with technical model adjustments.
• The implications for regions that may not have the resources to transition rapidly to MOVES5 are not fully addressed, potentially putting them at a disadvantage.
