Type: Rule
Date: 2018-07-05
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is approving portions of State Implementation Plan (SIP) submissions from Colorado, Montana, North Dakota, South Dakota and Wyoming addressing the Clean Air Act (CAA or Act) interstate transport SIP requirements for the 2012 annual Fine Particulate Matter (PM2.5) National Ambient Air Quality Standards (NAAQS). These submissions address the requirement that each SIP contain adequate provisions prohibiting air emissions that will have certain adverse air quality effects in other states. The EPA is approving portions of these infrastructure SIPs for the aforementioned states as containing adequate provisions to ensure that air emissions in the states will not significantly contribute to nonattainment or interfere with maintenance of the 2012 annual PM2.5 NAAQS in any other state.
Approval and Promulgation of Implementation Plans; Oklahoma; Interstate Transport Requirements for the 2012 PM2.5

The CAA's good neighbor provision requires EPA and states to address the interstate transport of air pollution that affects the ability of other states \1\ to attain and maintain the NAAQS. Specifically, the good neighbor provision requires each state in its SIP to prohibit emissions that will significantly contribute to nonattainment, or interfere with maintenance, of a NAAQS in another state. The District has submitted a SIP revision that addresses the good neighbor provision for the 2008 ozone NAAQS. In this action, EPA is proposing to approve the District's SIP as having adequate provisions to meet the requirements of the good neighbor provision for the 2008 ozone NAAQS in accordance with section 110 of the CAA.
