## Abstract

The EPA is partially approving and partially disapproving the State Implementation Plan (SIP) submittal from the State of Washington (Washington or the State) demonstrating that the SIP meets the infrastructure requirements of the Clean Air Act (CAA) for the National Ambient Air Quality Standards (NAAQS) promulgated for lead on October 15, 2008. The CAA requires that each state, after a new or revised NAAQS is promulgated, review their SIP to ensure that it meets the infrastructure requirements necessary to implement the new or revised NAAQS. On April 14, 2014, Washington certified that the Washington SIP meets the infrastructure requirements of the CAA for purposes of the 2008 lead NAAQS, except for those requirements related to the Prevention of Significant Deterioration (PSD) permitting program currently operated under a Federal Implementation Plan (FIP). The EPA has determined that Washington's 2008 lead SIP is adequate for purposes of the infrastructure SIP requirements of CAA section 110, with the exception of the requirements related to PSD permitting and portions of the interstate transport requirements. The EPA finds that the SIP deficiencies related to PSD permitting, however, have been adequately addressed by the existing EPA FIP and, therefore, no further action is required by Washington or the EPA. The EPA will address the remaining interstate transport requirements in a separate action.
