Presentation Transcript

  1. This and the following 10 slides are taken from EPA’s Governors’ Briefing (with several minor footnote and other deletions and additions). Clear Skies 2003 August 1, 2003

  2. Counties Currently Violating Fine Particle (PM2.5) and/or Ozone Standards (based on 1999-2001 data) Note: No violating counties in AK, HI, PR, or VI

  3. According to EPA, Clear Skies with Other Air Programs Would ALLEGEDLY Improve Fine Particle Attainment over the Next Two Decades Manhattan=red 129 Counties Exceed the Annual Fine Particle Standard in 2001 Manhattan=White PM2.5 standard = 15 µg/m3 Remaining 18 Counties Likely to Exceed the Annual Fine Particle Standard with Clear Skies in 2020

  4. Notes on EPA’s Analysis Using a “Base Case” • The EPA analysis compares new programs to a Base Case (Existing Control Programs), which is typical when calculating costs and benefits of Agency rulemakings. • The Base Case reflects implementation of current control programs only: • Does not include yet-to-be developed regulations such as those to implement the National Ambient Air Quality Standards. • The EPA 2003 Base Case for power sector modeling includes: • Title IV, the NOx SIP Call, NSR settlements, and state-specific caps in Connecticut, Massachusetts, Missouri, New Hampshire, North Carolina, Texas, and Wisconsin all finalized before March 2003. • For air quality modeling, the Base Case also includes the federal and state control programs in the EPA 2003 IPM Base Case, as well as the Tier II, Heavy Duty Diesel, and Non-Road Diesel rules.
