Samenvatting
This Notice announces the availability of two new EPA guidance documents for: completing quantitative particulate matter (PM 2.5 and PM 10 ) hot-spot analyses using EPA's Motor Vehicle Emissions Simulator model (MOVES), California's EMission FACtor model (EMFAC), and other models, and completing project-level carbon monoxide (CO) analyses using MOVES. These guidance documents will assist practitioners with implementing MOVES, EMFAC, air quality models, and applicable requirements. EPA is approving the latest version of the MOVES model (MOVES2010a) for official use for quantitative CO, PM 2.5, and PM 10 hot-spot analyses outside of California. This notice also announces a two-year grace period before the MOVES2010a emissions model is required to be used in quantitative CO and PM hot-spot analyses for project-level conformity determinations outside California. EPA is also approving the latest version of the EMFAC model (EMFAC2007) for quantitative PM hot-spot analyses for transportation conformity purposes within California.\1\ This notice announces a two- year grace period before EMFAC2007 is required to be used for quantitative PM hot-spot analyses for project-level conformity dete
