Revised Ozone Standard Briefing

• EPC Board Meeting
• January 15, 2009

2
National Ambient Air Quality Standard (NAAQS) for
Ozone Revised

• March 12, 2008 EPA revised the ozone standard
  from 84 parts per billion (ppb) to 75 ppb, based
  on an 8-hour average
• revisions reflect new scientific evidence about
  ozone and its effects on public health and the
  environment
• The final rule was effective on May 27, 2008

Ozone Compliance Values (based on 2006-2008 data)

Determination of Non-Attainment Area

• The EPAs presumptive non-attainment area will
  encompass the entire Core Based Statistical Area
  (CBSA)
• The CBSA for Hillsborough County includes
  Hillsborough, Pinellas, Pasco and Hernando
  Counties

5
Non-Attainment Designation

• Outside of the presumptive CSBA, states may argue
  for a larger or smaller area, based on an
  analysis of nine air quality-related attributes
• Air quality data
• Emissions data
• Population density
• Traffic and commuting patterns
• Growth rates
• Meteorology
• Geography and topography
• Jurisdictional boundaries
• Level of emission source control

6
Non-Attainment Designation Dates and Clean Up Plan

• March 12, 2009 the Governors recommendations
  defining the areas of nonattainment are due to
  EPA.
• March 12, 2010 EPA makes final determination of
  nonattainment areas
• March 12, 2013 the State Implementation Plan
  (SIP) is due to EPA
• 2013 or later (yet to be determined, based on the
  severity) nonattainment area to show compliance
  with new ozone standard

Implications

• Clean Up Plan
• Tougher standards for industry
• Cleaner gasoline/vehicles
• Conformity issues for growth
• Congestion Mitigation and Air Quality (CMAQ)
  monies for transportation projects
