Abstract
The Environmental Protection Agency (EPA) is partially approving the May 9, 2013, State Implementation Plan (SIP) submittal from Idaho to revise the SIP to update the incorporation by reference of Federal air quality regulations into the SIP and make minor edits and clarifications. The EPA is granting limited approval, as SIP strengthening, to a portion of the submittal that incorporates by reference updates to the Federal nonattainment new source review (nonattainment NSR) requirements that have been recently remanded to the EPA by a court. In addition, the EPA is partially disapproving Idaho's incorporation by reference of two provisions of the Federal prevention of significant deterioration (PSD) permitting rules that have been recently vacated in a separate decision by a court. Finally we are taking no action on Idaho's incorporation by reference of another provision of the Federal PSD permitting rules that has also been the subject of a court action. Upon the effective date of this action, the Idaho SIP will incorporate by reference certain Federal regulations as of July 1, 2012.
