Ozone Early Action CompactsClearing the Air in Tennessee

Prepared by the

Tennessee Department of Environment

and Conservation

for the

Tennessee Pollution Prevention Roundtable

June 2003

tennessee pollution prevention tp2 roundtable
Tennessee Pollution Prevention (TP2) Roundtable
  • Government, industry, universities, and environmental groups dedicated to preventing pollution
  • In 1998, met year 2000 goal of reducing emissions of toxic chemicals by 50% from 1989levels
  • Now focusing on reducing ozone levels through Early Action Compacts
what are early action compacts
What are Early Action Compacts?
  • Broad partnerships with government, business and citizens
  • Provide cleaner air for Tennesseans
  • Voluntarily improve air quality ahead of federal requirements
  • Implement local strategies for meeting the federal 8-hour ozone standard

ozone harms our lungs
Ozone harms our lungs…
  • Aggravates asthma
  • Reduces lung capacity
  • Increases vulnerability toillnesses like pneumonia and bronchitis
  • Can cause permanent lung damage after long-term exposure
  • Affects especially children, elderly, those with respiratory problems, and those who spend much time outdoors
ozone harms our economy
Ozone harms our economy…
  • Affects tourism
  • Reduces crop and forest yields
  • Restricts economic development
  • Threatens federal highway funds

Ozone in the Smokies damages 30 species of plants, causing visible leaf injury and growth reductions.

what causes nearby ozone
What causes nearby ozone?

Nitrogen oxides (NOx) + volatile organiccompounds (VOCs) + certain weather = Ozone

  • Sources of NOx
  • Motor vehicles
  • Electric utilities
  • Industrial, commercial and residential sources that burn fuel
  • Sources of VOCs
  • Motor vehicles
  • Stationary sources
  • Solvents, lawn and garden equipment
  • Trees

how is ozone regulated
How is ozone regulated?
  • EPA sets federal air quality standards
    • Old 1-hour standard .12 ppm
    • New 8-hour standard .08 ppm
  • State monitors ozone levels
  • EPA designates nonattainment areas
what does nonattainment mean
What does “nonattainment” mean?
  • Measured ozone levels can exceed the health-based standard
  • The air is not always healthy to breathe
how would nonattainment affect my county
How would nonattainment affect my county?
  • Public stigma of nonattainment
  • Impacts on economic development
  • Tougher permitting for industry
  • Industrial recruitment difficult
  • Highway funds can be held back

how will the new 8 hour ozone standard affect tennessee
How will the new 8-hour ozone standard affect Tennessee?
  • New standard much more demanding
  • Many Tennessee counties will NOT meet new standard without additional controls
  • Industrial controls alone not sufficient— must also reduce vehicle emissions
  • Local support and participation needed to attain new standard
what has epa done to reduce ozone
What has EPA done to reduce ozone?
  • NOx reductions from TVA and large industrial boilers
  • Low-sulfur gasoline (phased in 2004 -2007)
  • New emission standards for passenger cars (phased in 2004 - 2007)
  • New on-road diesel engine and fuel standards (phased in 2006 - 2010)
what can tennesseans do to reduce ozone
What can Tennesseans do to reduce ozone?
  • State air pollution regulations to reduce emissions from factories and power plants
  • Reducing emissions from low-level sources will have greatest local impact
  • Local requirements to reduce vehicle emissions
  • Voluntary actions by government, business and citizens
  • State writes control measures into a State Implementation Plan (SIP)
what have tennessee s eac partners committed to do
What have Tennessee’s EAC partners committed to do?
  • Take early action to reduce ozone levels
  • Actively participate in selecting and implementing local control measures
    • State leads on technical work and regulates stationary sources outside of local programs
  • Implement voluntary and regulatory strategies that address all sources
deadlines for tennessee
Deadlines for Tennessee
  • June 16, 2003: State sends EPA likely control measures for each compact
  • March 2004: Local areas submit air quality improvement plan to state
