  1. 2010 PASBO Conference – “Diesel School Buses: What to Expect in 2010” March 11, 2010Eric Cheung, Esq.Philadelphia Diesel Difference Coordinator/Clean Air Council Senior Attorney

  2. and the big news story for 2010…Yellow Buses Are Turning Green Who? What? When? Where? Why? How?

  3. Who? What? When? Where? Why? How?

  4. Who I am • Clean Air Council (www.cleanair.org) • Nonprofit, since 1967 • Protect everyone’s right to breathe clean air • Six program areas • Senior attorney • Philadelphia Diesel Difference Working Group (www.cleanair.org/dieseldifference) • Public/Private partnership, since 2003 • Voluntary adoption of clean diesel technologies and strategies • Retrofits, Clean Fuels, Idling Reduction • Co-coordinator with Philadelphia Air Management Services

  5. Philadelphia Diesel Difference (PDD) • Accomplishments… • Have held four clean diesel workshops, with a fifth one planned for Summer, 2010 • Convened three Mid-Atlantic clean ports conferences • Financial support from members • Successes: Wissahickon School District, West Chester S.D., N. Penn S.D., Upper Darby S.D., Unionville-Chadds Ford S.D., Upper Moreland S.D., Garnet Valley S.D., City of Philadelphia, School District of Philadelphia, Upper Darby S.D., Amtrak, SPC Corp., Packer Terminal, and Evans Network of Companies (to be completed by 2011) • 31 heavy duty fleets (representing 6,700 vehicles) have signed onto the “Interested Fleets” list

  6. Who I am NOT • A technology vendor • A scientist • A mechanic • An engineer • A professor • Anyone who has technical knowledge about diesel vehicles • BUT, PDD can connect you with the right people to answer your technical questions.

  7. Who is this story about? • YOU! • On Road • Heavy Duty • Diesel-powered • Trucks and buses • But, not construction, agricultural, marine, railroad or port equipment

  8. Who? What? When? Where? Why? How?

  9. New Rules • 2010 Heavy Duty Diesel Engine Rule • Promulgated by the U.S. Environmental Protection Agency • Nitrogen Oxides (smog-forming gases) must be reduced to 0.2 g/BHP-hr (83% expected reduction, on average) • Model Year 2010 • Pennsylvania Diesel Idling Restrictions - Act 124 of 2008 • Promulgated by the PA Department of Environmental Protection • No idling for more than 5 minutes an hour • “No Idling” signs must be posted • $150 - $300 in penalties

  10. Who? What? When? Where? Why? How?

  11. Time Line of Events • 2001 - Heavy Duty Highway Diesel Rule • 2006 – Ultra Low Sulfur Diesel Fuel • 2007 – Particulate Emission Standards • 2009 – PA Anti-Idling Law • 2010 – NOx Emission Standards • THIS MEANS THAT TODAY… • NOx and Particulate Emission Standards are in effect for any new heavy duty school bus you purchase • School buses cannot idle for more than 5 minutes an hour (15 minutes with passengers) • Facilities where 15 or more school buses park MUST have at least one “No Idling” sign in place

  12. Who? What? When? Where? Why? How?

  13. Geographic Scope • 2010 Heavy Duty Diesel Engine Rule – Federal • Any school bus produced or imported in the United States • Producer/manufacturer of the school bus is on the hook • Pennsylvania Diesel Idling Restrictions - Act 124 of 2008 • Applies Statewide • No new local anti-idling rules, but does not supersede existing rules (Allegheny County, Philadelphia) • Pennsylvania Department of Environmental Protection enforces, but so can local police departments as a traffic violation • Owners and drivers of the school bus are on the hook • Owners and operators of locations where 15 or more school buses park are on the hook for signage requirements

  14. Who? What? When? Where? Why? How?

  15. Diesel Emissions 101 • Fine Particulate Emissions • Particles that are mostly elemental carbon (soot) • <= 2.5 micrometers in size • 2006 fuel standards and 2007 heavy duty vehicle emission standards resulted in a 90% reduction • Ozone (Smog) • Nitrogen Oxide is a precursor to this gas • 2010 emission standards will result in 83% reduction ofNOx • Health impact of diesel exhaust • Respiratory illnesses, can cause or exacerbate asthma, decrease in lung function growth, premature death • Cancer risks associated with prolonged exposure • Large urban centers of Pennsylvania do not meet minimum federal health standards for ozone or fine particulates

  16. Diesel Emissions 101 – Cont’d • Global Warming • 1 gallon of diesel = 22 pounds of carbon dioxide • Current emission standards are not intended to address carbon dioxide, but idling reduction strategies can help reduce impact • PA statistics for diesel vehicles • 7.5% of total vehicle miles traveled in Pennsylvania • 48% of smog-forming compounds from highway vehicles • 65% of fine particulates from highway vehicles

  17. Who? What? When? Where? Why? How?

  18. Compare and Contrast • 2007 School Buses • The emissions reduction focus is on particulates • Relies on diesel oxidation catalysts and diesel particulate filters • Ultra low sulfur diesel fuel is required • Increased costs, but technology is not too much more expensive • 2010 School Buses • The emissions reduction focus is on nitrogen oxides • Most likely relies on selective catalytic reduction (SCR) or advanced exhaust gas recirculation (EGR) • Diesel exhaust fluid is needed for SCR in addition to ultra low sulfur diesel • Potential for significant increases in costs for technology

  19. In This Corner - SCR • Selective Catalytic Reduction • Catalyst reacts with exhaust downstream of DPF • Chemical reducing agent is sprayed into the catalyst • NOx altered to become N2 and H2O • Diesel Exhaust Liquid (DEF) • Chemical reducing agent is urea • Has separate storage container from the fuel • Reductant delivery system determines effectiveness • Manufacturers • Cummins, Detroit Diesel, Mack, Paccar, Volvo • OE experience outside the U.S. = 200,000 vehicles • Benefits – 60-80% NOx reduction; 20-40% PM, 70+% HC, slight possible fuels savings for on highway trucks

  20. In This Corner - EGR • Advanced Exhaust Gas Recirculation • Enhances existing technology to reduce NOx • Advanced high-pressure fuel injection technology • Combustion bowl optimization • Sophisticated air-management systems. • Advanced electronic calibration • Burns the exhaust a second time • Goal is to lower combustion temperatures in order to decrease production of NOx. • Manufacturers • Navistar/International • Limited experience with this strategy, but based on widely used technology • Slight possible fuel economy loss (recirculated exhaust has lower energy content) • Benefits – 40% NOx reduction

  21. FIGHT!

  22. Other Technologies • Lean NOx Catalyst • Different type of Catalyst • Diesel fuel as a reductant agent • 25% reduction in NOx • Compressed Natural Gas • Inherently cleaner fuel • No need for SCR or EGR • Hybrid Electric Diesel • Hydraulic Hybrids • Fuel Cell??

  23. Anti-Idling Technologies • Auxiliary Power Units • Automatic Start/Stop • Truck Stop Electrification • Anti-Idling Policies • PA School Bus Anti-Idling Campaign • Lower Merion, North Penn, Spring-Ford, Unionville-Chadds Ford, Romano School Bus Service • http://www.cleanair.org/Transportation/idling.html • IdleFreePA • NOTE: Does not meet 2010 NOx emission standards

  24. Funding Opportunities • Federal EPA – Diesel Emissions Reduction Act • Most recent opportunity = $500,000 to $2.5 million for the Mid-Atlantic Region in December, 2009 • Economic Stimulus opportunity = $1 to $7 million for the Mid-Atlantic Region last year • PADEP – Alternative Fuels Incentive Grant • Compressed Natural Gas • Hybrid Electric • Biodiesel • Become a Philadelphia Diesel Difference Interested Fleet • Philadelphia, Radnor, Colonial, Coatesville, Kennett Consolidated, Downingtown Area, Springfield, Lower Merion, Haverford, Krapf Bus Co.
