Abstract
The Environmental Protection Agency (EPA) is taking direct final action to approve a State Implementation Plan (SIP) revision submitted by the State of Idaho (Idaho or the State) on April 21, 2014, to amend the Portneuf Valley maintenance plan for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM<INF>10</INF>). The SIP revision updates the on-road motor vehicle emissions inventory and motor vehicle emissions budgets (MVEBs) using the EPA's Motor Vehicle Emissions Simulator (MOVES2010b) and the most recent road dust emission factors. This rulemaking action approves the SIP revision and thereby makes the MVEBs available for transportation conformity purposes. The EPA is approving this SIP revision because it is consistent with the Clean Cir Act (CAA).
