Presentation Overview

• Air Quality Concerns with Diesel Exhaust
• Impacts of Idling
• Benefits of Idle Reduction
• Specifics of Proposed New Rule

3
Diesel Exhaust Composition

• Ozone forming pollutants
• Nitrogen Oxides (NOx)
• Volatile Organic Compounds (VOCs)
• Carbon Monoxide (CO)
• Sulfur compounds
• Formaldehyde
• Benzene
• Particulate Matter (PM)

4
Impacts of Idling

• Average heavy duty diesel engine consumes 0.8
  gallons of diesel fuel per hour of idling
• Each year idling consumes more than 960 million
  gallons of diesel fuel
• It generates
• 11 million tons of CO2
• 180,000 tons of NOx
• 5,000 tons of PM

Why Regulation Needed?Air Quality Issues In
Kansas City

• Kansas City currently violates both 1997 and 2008
  8-hour ozone standards
• 2007 Kansas City Ozone Maintenance Plan committed
  to an idle regulation if violations occurred
• Quality assured violations occurred during 2007
  ozone season

Why Regulation Needed?Air Quality Issues In St.
Louis

• St. Louis currently violates the 1997 and 2008
  ozone standards
• 2007 St. Louis Ozone Nonattainment SIP discusses
  an idle reduction rule
• The area is currently designated as a
  nonattainment area for PM 2.5 annual standard

7
Idle Reduction Benefits

• Reduce emissions that contribute to ozone
  formation and pollutant exposure
• Saves fuel and money for drivers
• Reduces the overall demand for diesel fuel
