Riepilogo
The Environmental Protection Agency (EPA) is proposing to approve state implementation plan (SIP) revisions submitted by the District of Columbia (the District), State of Maryland (MD), and Commonwealth of Virginia (VA). The revisions update the motor vehicle emissions budgets (MVEBs) and the onroad and nonroad (except for marine, airport, and railroad) mobile emissions for volatile organic compounds (VOC) and nitrogen oxides (NO X ) for the years 2025 and 2030. EPA proposes to approve the updated MVEBs and updates to the applicable onroad and nonroad mobile emissions for VOC and NO X for the years 2025 and 2030. EPA is also approving the allocation of a portion of the safety margins for VOC and NO X in the ozone maintenance plan to the 2025 and 2030 MVEBs. The MVEBs will be available for transportation conformity purposes, in accordance with the requirements of the Clean Air Act (CAA).
