  1. Washington Diesel Retrofit Programs Presented To: WRAP Mobile Sources Forum Workshop June 7, 2007 Portland, OR Presented By: Mike Boyer Diesel Programs Coordinator Washington Dept. of Ecology

  2. Motor Vehicle Account County-based $5 title transfer fee 5 Yrs / $24.4 M Retrofits: school buses (priority), public and privately owned vehicles Other Uses: administration, fuel infrastructure, operations modification that reduce toxic emissions, special studies, inventories, etc. Toxics Control Account 0.7% tax of wholesale value on hazardous substances 4 Yrs / $9.17 M Retrofits: transit buses, city/county vehicles, port equipment, school buses Other: fuel infrastructure or operations modification that reduce diesel emissions Federal Grants Retrofit Funding Sources

  3. State Retrofit Programs • Washington Clean School Bus Program: direct funds pass through to local air agencies • Local Governments Diesel Retrofits Program: Ecology operated grants program to cities, counties, port authorities, and transit authorities

  4. Roles and Responsibilities: • State Procurement Office: contract management • Ecology: state fiscal and project management, diesel technical support, grants management, use state funds to leverage federal funds • Seven Local Air Agencies: local fiscal and project management, use state funds to leverage federal funds • Puget Sound Clean Air Agency: “Diesel Emissions Solutions” Program: initiate and manage own contracts

  5. Department of Ecology’sDiesel Emission Reduction Strategy:Retrofit Priorities and Technologies • School Buses: DOC, DPF, or CARB Level 2 Device; CCV Filter • Transit Buses: DPF or DOC; CCV Filter • Refuse Vehicles: DOC or CARB Level 2 Device • Public Maintenance/Utility Vehicles: DOC • Other Vehicles and Equipment: DOC

  6. State Retrofit Contracts • GA’s State Procurement Office • Convenience Based Purchasing • Multiple Users: state agencies, local air authorities, Local governments, school districts • Fixed prices based upon vehicle type and engine HP • One Year Term – Renewable • EPA or CARB verified technologies

  7. State Retrofit Contracts: Three Contracts with Two Contractors • School Buses: DOC and CCV filter • City, county, state, transit, and port vehicles and equipment: DOC and CCV filter • School and transit buses: CARB Level 2 and CARB Level 3 Device • Other (Developing): DPF filter cleaning machines

  8. Program Provisions • 100% for parts and installations • 1-2 years for CCV replacement filters • 1-3 years for DPF regeneration • Technical assistance

  9. Challenges / Successes Diesel emissions reductions vs. vehicle retrofits (retrofits, idle reduction, emissions testing, engine maintenance, alternative fuels, education outreach, etc.)

  10. Challenges / Successes Meeting Customers Expectations: • Schedules • Communication

  11. Challenges / Success: Matching Retrofit Technology to Vehicle/Equipment

  12. Challenges / Successes CCV Filter Installations

  13. Challenges / Successes DPF Maintenance • Soot/ash loaded DPF • Cracked/melted DPF • DPF regeneration Pneumatic DPF Cleaner Thermal DPF Cleaner http://www.osti.gov/bridge/servlets/purl/827991-gPfYAF/native/827991.pdf

  14. Challenges / Successes Contractors should have: • Diesel engine expertise and good public relations skills • Appropriate resources to meet schedules

  15. Retrofit Programs Are Like Marriage Vows: • For better, for worse; • In sickness and in health; • Till death do us part.
