  1. Regulations to Restrict Idling of Diesel-Powered Vehicles Philadelphia Diesel Difference June 18, 2007 Arleen ShulmanBureau of Air Quality, Pennsylvania Department of Environmental Protection

  2. Petition to EQB (and PennDOT) • October 18, 2006 -- Clean Air Board of Central PA, Inc., • January 17, 2007, EQB accepted for study. • March-April 2007 CAB commented on draft study • May 2007 – EQB directed DEP to develop proposed regulation • All posted on EQB’s website.

  3. Idling Concerns Identified in the Petition • Idling highway diesel engines are a significant source of diesel pollution, which include fine particulate matter (PM2.5), ozone precursors, and air toxics. • PM2.5 poses serious public health and environmental problems in many areas of the Commonwealth. • Statewide regulation of idling would prevent a patchwork system of regulations in Pennsylvania. • Idling diesel engines increase emissions and waste fuel. • Cost-effective technologies to reduce idling are available today.

  4. The Department’s Study • Characterized and quantified heavy-duty diesel vehicle long-duration (>15 minutes) idling activity. • Estimated emissions impacts of idling activity. • Investigated legal authority and enforcement issues. • Used consultant assistance. • Incorporated consultation with PennDOT and State Police.

  5. Health and Environmental Benefits • Agreed with CAB’s assessment of health effects of diesel emissions. • Effects include contribution to area-wide concentrations of fine particulates and ozone, and direct exposure to diesel emissions. • An anti-idling regulation would help the Commonwealth address local concentrations of PM2.5 and contribute towards attaining and maintaining the fine particulate and ozone standards. • Agreed that idling reduction can save energy and money for the industry and that cost-effective technology exists to reduce idling.

  6. Idling Activity • Study looked at heavy-duty diesel idling from long-haul truck travel rest at truck/rest stops and at loading/unloading locations, transit and tour buses, school buses. • Truck travel rest idling accounts for nearly 80 percent of all heavy-duty diesel idling. • Most travel rest idling occurs at truck/rest stops. • More than 13,000 truck parking spaces at about 300 stops and rest areas in Pennsylvania

  7. Idling Activity Heavy-Duty Diesel Vehicle Idling • Total • 27.2 million vehicle hours statewide • Long-Duration (>15 min.) • 22.3 million vehicle hours • Long-Duration due to long-haul travel rest • 21.2 million vehicle hours

  8. = Daily Truck Volume > 10,000 = Daily Truck Volume >2,000 and <10,000 Geography Primary interstates carry the most truck volume.

  9. Geography

  10. Emissions from Heavy-DutyLong-Duration Idling (2005) • Nitrogen oxides (NOx) and PM2.5 significant. • Smaller but still significant impact on volatile organic compounds, carbon monoxide, and carbon dioxide. • Statewide; varies by county depending on activity.

  11. Enforcement • With a regulation, DEP inspectors and state and local police would have the ability to enforce. • DEP has authority for administrative penalties and summary offenses. • State and local police cannot use administrative penalties and generally cannot enter private property (eg. warehouses) without a warrant. • Since most idling is due to truck travel rest at truck/rest stops, targeted education campaigns in selected areas may be more effective in reducing idling emissions than responding to individual complaints.

  12. Regulatory Development PROPOSED • July 2007: meet with DEP advisory committees • September 2007: EQB considers proposal • October or November 2007: public comment period opens (60 days with three public hearings) FINAL • April/May 2008: meet with DEP advisory committees on final rule • September 2008: EQB considers final rulemaking • October 2008: Independent Regulatory Review Commission • November 2008: publication/effective

  13. Regulatory Development • Considering petitioner’s language, EPA model law, Philadelphia and Allegheny county laws. • Regulation itself will not contain penalty amounts. • State regulation would preempt local regulation only where more stringent, which creates consistency issues.

  14. Issues • Form of time restriction • Who’s responsible? • Sleepers, temperature exemptions • Expiration of sleeper exemptions • Loading/unloading, queuing • 2007+ engines being cleaner than auxiliary power units.
