In this action, in response to a petition for reconsideration, EPA is proposing two actions that would end EPA's 1997 policy that allows sources and permitting authorities to use a demonstration of compliance with the prevention of significant deterioration (PSD) requirements for particulate matter less than 10 micrometers (PM<INF>10</INF>) as a surrogate for meeting the PSD requirements for particulate matter less than 2.5 micrometers (PM<INF>2.5</INF>). First, in accordance with the Administrator's commitment to the petitioners in a letter dated April 24, 2009, the EPA is proposing to repeal the "grandfathering" provision for PM<INF>2.5</INF> contained in the Federal PSD program. Second, EPA is proposing to end early the PM<INF>10</INF> Surrogate Policy applicable in States that have an approved PSD program in their State Implementation Plan ("SIP-approved States").
