On-Road Section: Overview: On-Road Section: Overview Background
Diesel Exhaust and Health
Non-attainment Designation
National Efforts to Reduce Emissions from On-Road Vehicles
Need for Local Programs to Achieve Standards
Recommendations for On-Road Fleets
Regulatory Approach
Voluntary Approach
Background: Background Benefits of diesel power
Dominant power source for school bus fleets, transit buses, waste collection vehicles, public works vehicles, short-haul freight, dump trucks and cement mixers
Diesel Exhaust and Health: Diesel Exhaust and Health Link between diesel emissions and health
Respiratory hazard
Aggravates asthma
Sensitive populations
Risk of lung cancer
Carcinogenic properties of diesel exhaust
Average range of lung cancer risk
Premature death
Need more research – Recommended resources?
Non-attainment Designation: Non-attainment Designation Do not meet 8-Hr Ozone and PM2.5 Standards
SIP Deadlines
Ozone SIP – June 2007
Show attainment – 2009
PM2.5 SIP – April 2008
Show attainment - 2010
Non-attainment and On-Road Diesel Emission Reductions: Non-attainment and On-Road Diesel Emission Reductions Why are we looking at on-road diesel emission reductions to help us attain the ozone and PM2.5 standards?
What portion of the total central Ohio NOx and PM2.5 inventories are attributed to on-road diesel vehicle?
Review of National Efforts to Reduce Emissions from On-Road Diesel Vehicles: Review of National Efforts to Reduce Emissions from On-Road Diesel Vehicles 2007 Highway Diesel Rule
Applies to new engines only
11 million legacy diesels
Clean School Bus USA Grant Program
Limited funding available
SmartWay Transport Partnership
Voluntary, offer technical guidance, recognition opportunities
Critical Need for Local On-Road Emission Reduction Programs: Critical Need for Local On-Road Emission Reduction Programs National efforts will help, but still need to address on-road legacy fleets
11 Million diesels
If local and state govt.s do not address emissions from in-use diesel, it will be difficult to comply with Federal air quality standards
Regulatory Approach: Regulatory Approach Govt.-owned public works fleets
Urban transit fleets
Waste collection vehicles
Regulatory Approach –Cont.: Regulatory Approach –Cont. Fleet selection arguments:
Public sector leadership
Govt. should lead the way
Operating environment
Close proximity to dense populations
Regulatory Approach –Cont.: Regulatory Approach –Cont. Fleet selection arguments – Cont.:
Emission Characteristics
Transit buses emit more grams of NOx per mile than any other vehicle class
Public Works Vehicles – can we break these down into on GVWR class?
Waste Collection Vehicles – any ideas?
Regulatory Approach –Cont.: Regulatory Approach –Cont. Fleet selection arguments – Cont.:
Funding Sources
FTA Transit Bus Funding
Municipal Fleets can recoup their cost through higher utility service fees.
Waste collection fleets can renegotiate collection contracts
CMAQ
DERA
Regulatory Recommendations: Regulatory Recommendations OEPA should fund a study to obtain fleet inventories of all government-owned public works vehicles and waste collection fleets (public and private) in central Ohio’s six non-attainment counties.
Ohio EPA should develop new rules requiring these fleets to install best available control technology (BACT) on these vehicles phased in over a period of years.
Ohio EPA should define BACT guidelines, i.e., what control technology will best reduce PM and NOx emissions from particular model year engine.
Build into the program extensions and or exemptions for special circumstances. Smaller waste collection businesses and local governments may not be able to comply as quickly as a larger businesses and governments
Voluntary Program: Voluntary Program Short-haul freight trucks
Dump trucks and cement mixers
School Bus fleets
Voluntary Program – Cont.: Voluntary Program – Cont. Fleet Selection Arguments:
Incentive
Unlike public fleets, private fleets do not have much of an incentive to clean up their fleets
School Buses excluded, but lack funds
Local Fleets
All three fleets are restricted
Voluntary Program – Cont.: Voluntary Program – Cont. Fleet Selection Arguments:
Emission Characteristics
School buses are old and dirty. Emit more grams of NOx per mile than any other vehicle class
Children are highly susceptible to effects of particle pollution
Short-haul truck emissions – Are there any national statistics? Are these mostly Class 8B?
Cement mixers and dump trucks – suspect they are dirty but need to fund inventory analysis
Voluntary Program Recommendations: Voluntary Program Recommendations OEPA should fund a project to obtain fleet inventories for school bus fleets, short-haul freight trucks, and cement mixers and dump trucks in central Ohio’s six non-attainment counties.
OEPA should establish a state funded grant or loan program to assist both public and private fleets with the purchase and installation of emission control equipment.
Establish a marketing campaign to provide public and private fleet managers with the technical resources needed to install emission control equipment.
