40 CFR Part 52
Agency: Environmental Protection Agency (EPA)
Action: Proposed rule
Summary: EPA is proposing to approve portions of a State Implementation Plan (SIP) revision submitted by the State of Oregon on December 10, 2010 and supplemented on February 1, 2011, as meeting the requirements of Clean Air Act (CAA or the Act) section 169A and B and Federal Regulations in 40 CFR 51.308. In a previous action on July 5, 2011, EPA approved portions of the December 10, 2010, SIP submittal as meeting the requirements for interstate transport for visibility of CAA section 110(a)(2)(D)(II) and certain requirements of the regional haze program including the requirements for best available retrofit technology (BART). 76 FR 38997. The action in this Federal Register notice addresses the remaining requirements of the CAA and EPA’s rules that require states to prevent any future and remedy any existing anthropogenic impairment of visibility in mandatory Class I areas caused by emissions of air pollutants from numerous sources located over a wide geographic area (also referred to as the ‘‘regional haze program’’). In this action, EPA proposes to approve the remaining regional haze SIP elements for which EPA previously took no action in the July 5, 2011 notice.
