The Stink Over Diesels

• Its a Good Idea to Shut It Down Reducing
  Unnecessary Idling

The Decade of the Diesel

• Health Studies show problems with diesel exhaust
• Causes allergy symptoms, including inflammation
  and irritation of airways
• Exacerbates bronchitis and pneumonia decreases
  lung function triggers asthma
• Identified as a probable human carcinogen
• Causes premature mortality - death

3
The Decade of the Diesel

• Whats in Diesel Exhaust thats so bad?
• Carbon Monoxide
• Ozone Precursors VOCs and NOx
• Other Air Toxics and Greenhouse Gases
• Particulate Matter much more than cars
• Smoke what you see from the tailpipe
• TSP contributes to hazy skies
• PM 10 - invisible
• PM 2.5 inhalables go directly to the lungs

4
Where Does PM Come From?
NOW
AFTER NEW ENGINE FUEL RULES TAKE EFFECT
5
Smoke, TSP, PM 10 and PM 2.5

• Transport - mostly from states south and west of
  us, but theres always an exception

The Decade of the Diesel

• Public Policy will reflect Health Studies
• New engine standards
• New fuel standards (diesel and gasoline)
• Pressure to retrofit
• Enforcement actions
• Cleaner alternative fuels
• Anti-Idling campaigns

8
Whats Coming Federal New Engine Standards
9
Whats Coming Cleaner Fuel

• Current highway diesel has approximately 500 ppm
  sulfur content
• Ultra Low Sulfur Diesel (ULSD) with 30 ppm
  sulfur, is available now in limited quantities
• In 2006 Ultra Low Sulfur Diesel with 15 ppm
  sulfur is required nationwide for all highway
  vehicles

10
Whats Coming - Retrofits

• Oxidation Catalyst
• Doesnt need cleaner Ultra Low Sulfur Diesel
  fuel
• Very little maintenance
• Reduces PM 20 - 30
• Diesel Particulate Filter (DPFs)
• Requires Ultra Low Sulfur Diesel (ULSD)
• Needs regular maintenance
• Reduces PM 60 - 90

11
Whats Coming Effects of DPFs
12
Right Now - School Buses

• High and enviable safety record
• MA Schools Buses received a B pollution grade
  in 2002 from the Union of Concerned Scientists
• Look for increasing pressure to become greener
• School bus retrofits
• anti-idling

13
Whats Coming School Bus Retrofits

• Retrofits available
• Who pays?
• Schools?
• Companies?
• Other methods
• Supplementary Environmental Projects
• State revolving fund California
• Grants Puget Sound

14
Whats Coming School Bus Anti-Idling Actions

• Using the 30 year old MA Anti-Idling law
• Reduced Idling policies by bus companies and
  associations
• Schools actions - Pollution-Free School
• Annual State License Re-certification will
  include anti-idling training in the future
• Drivers Shut It Down You Hold the Key

15
School Buses Both Yellow Green

• Enviable safety record for your precious cargo
• Bad equation
• Fewer pupils riding buses
• More private vehicle trips More Pollution
• How green will school buses be?
• Drive Clean
• YOU Hold the Key
