Presentation Transcript

  1. Presentation to the Joint Legislative Audit CommitteeMay 9, 2002Air Quality Benefits of Wisconsin’s Motor Vehicle Inspection Program

  2. I/M Air Quality Benefits • Ozone • VOC, NOx, & CO • Carbon Monoxide • Fine Particles • VOC & NOx • Other Toxic Compounds • Benzene, 1,3 Butadiene, Xylene, Toluene

  3. Health Effects • Ozone • Decreased Lung Function • Change in Lung Structure (Lung Scarring) • Degraded Immune System • Triggers Asthma Attacks

  4. Health Effects • Fine Particles • Premature Death • Increased Respiratory Disease • Decreased Lund Function • Changes to Lung Structure

  5. Health Effects • CO • Heart Attacks • Study by Dr. Robert Morris from the Medical College of Wisconsin - Amer. Jour. Pub. Health • Other Toxic Substances • Benzene, 1,3 Butadiene, Xylene, Toluene • Leukemia, Lung Cancer

  6. Health Effects - Cost/Benefit • 4 to 1 Ratio - Health Benefit to Air Quality Program Cost • March 19 - White Office of Management and Budget • British Study - 12,700 - 19,500 Deaths Annually - Mostly from Motor Vehicles

  7. I/M Regulatory Benefit • 15% Plan • ~20 tons/day out of 51 tons/day • 9% Plan • ~24 tons/day out of 82 tons/day • Attainment Demonstration Rate of Progress • ~40 tons/day out of 163 tons/day • Redesignation Request • Conformity

  8. I/M Clean Air Act Requirements • Severe Ozone Nonattainment Areas • Milwaukee - Low Enhanced I/M • Performance Standard • State Flexibility to Design Program • Important to Leave a Safety Margin in Program Design • Moderate Nonattainment Areas • Sheboygan • Relatively Low Hurdle

  9. Sheboygan County I/M Program • Difference from Low-Enhanced Program in Milwaukee • Repair Cost Waiver $200 and $75 v. $450 • Policy Decision • More Emission Reduction • Cheaper • Easier to Manage • More Flexibility for Motorists

  10. Contribution to Ozone Formation - VOC

  11. Contribution to Ozone Formation - NOx

  12. Future Considerations • 8-Hour Ozone Standard • March 26, 2002, DC Circuit Court Ruling • Some Additional Legal Hurdles • EPA to Develop an Implementation Plan • 2004 or 2005 Nonattainment Designations • Opportunity to Reduce Design Value • Lower Classification • Avoid Nonattainment Designation

  13. Future Considerations • Fine Particles • March 26, 2002, DC Circuit Court Ruling • EPA to Develop an Implementation Plan • 2004 or 2005 Nonattainment Designations • Continue Attainment Status

  14. Current Fine Particle Monitoring

  15. I/M Program Evaluation • Joint DOT and DNR Evaluation • Comprehensive I/M Program Evaluation • Efficiencies, Improvements & Cost Savings • Stakeholder Input • Completed by December 31, 2002 • Report to the Natural Resources Board and the Legislature

  16. Presentation to the Joint Legislative Audit CommitteeMay 9, 2002Air Quality Benefits of Wisconsin’s Motor Vehicle Inspection Program
