The Environmental Protection Agency (EPA) is proposing to approve two state implementation plan (SIP) revisions submitted by the District of Columbia (the District). Under the Clean Air Act (CAA), states' SIPs must require stationary sources in ozone nonattainment areas classified as marginal or above to report annual emissions of nitrogen oxides (NO<INF>X</INF>) and volatile organic compounds (VOC). This emissions statement requirement also applies to stationary sources located in attainment areas within the Ozone Transport Region (OTR) that emit or have the potential to emit at least 50 tons per year (tpy) of VOC or 100 tpy of NO<INF>X</INF>. The District formally submitted as a SIP revision, a statement certifying that the District's existing SIP-approved emissions statements program satisfies these CAA requirements for the 2008 ozone National Ambient Air Quality Standards (NAAQS). Upon review of the District's submittal, EPA noted minor discrepancies between the District's SIP-approved provisions, including the provision containing the District's emissions statements requirements, and the current edition of the District of Columbia Municipal Regulations (DCMR) referenced in the District's submittal. Therefore, to correct these minor discrepancies and update the District's SIP, the District also formally submitted a revised edition of the sections of the DCMR which address the discrepancies. EPA is proposing to approve the District's SIP with the current edition of these SIP-approved provisions. EPA is also proposing to approve the District's emissions statements program certification for the 2008 ozone NAAQS. EPA is proposing to approve these SIP revisions in accordance with the requirements of the CAA.
