Under the Clean Air Act (CAA), states' SIPs must require stationary sources in ozone nonattainment areas to report annual emissions of nitrogen oxides (NOX) and volatile organic compounds (VOC). 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 addresses 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. ## Source - [Federal Register document](https://www.federalregister.gov/documents/2019/06/12/2019-12294/approval-and-promulgation-of-air-quality-implementation-plans-district-of-columbia-administrative) --- *AI Analytics · CC0 1.0*
