Retrofit Funding Sources
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
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
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
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
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
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
Program Provisions
• 100% for parts and installations• 1-2 years for CCV replacement filters• 1-3 years for DPF regeneration• Technical assistance
Challenges / Successes
Diesel emissions reductions vs. vehicle retrofits
(retrofits, idle reduction, emissions testing, engine maintenance, alternative fuels, education outreach, etc.)
Challenges / Successes
Meeting Customers Expectations:
• Schedules
• Communication
Challenges / Success:
Matching Retrofit Technology to Vehicle/Equipment
Challenges / Successes
CCV Filter Installations
Challenges / Successes

Challenges / Successes
Contractors should have:• Diesel engine expertise and good public
relations skills• Appropriate resources to meet schedules
Retrofit Programs Are Like Marriage Vows:
• For better, for worse;• In sickness and in health;• Till death do us part.
