First, someone will give an overview of air quality concerns and current statistics. Next, there will be a presentation of propane buses and how they fit with improving air
quality and cutting costs. Next, administrators will talk about how their districts have incorporated language into their RFP and contracts to encourage more environmentally friendly buses for their students.
2. Asthma is a problem
Every day in America:
40,000 people miss school or work due
to asthma
30,000 people have an asthma attack
5,000 people visit the emergency room
due to asthma
1,000 people are admitted to the
hospital due to asthma
11 people die from asthma
3. What is Asthma?
• An immune response in the small airways
of the lungs, characterized by
– Inflammation and edema (swelling)
– Mucus production (snot)
– Bronchospasm (muscle tightness)
Drawings from M. Tsutsumi
4. Asthma triggers
• Asthma can be triggered by
many airborne factors:
– Pollen (trees, grasses, ragweed)
– Mold spores
– Air pollution
• Exhaust from vehicles
– School buses, trucks
– Small engines (eg, lawn mowers)
– Boats and cars
• Factory smoke / exhaust
5. Air Pollution
• Ozone (O3)
– An invisible gas formed through chemical reactions of
nitrous oxides and volatile organic compounds
– Able to chemically react with lung tissue leading to tissue
damage

8. Air Pollution
• Particle Pollution
– A mix of airborne solids and liquids
– Comes from burning fossil fuels in factories, power plants,
steel mills, smelters, diesel/gasoline, wood (even from
residential fireplaces).
– May trigger asthma possibly leading to hospitalization and
death
10. Particle Size
• Size matters
– > 10 µm impact in the nose and mouth
– < 5 µm can impact in the lungs
nose and mouth
trachea (large airways)
bronchioles (small airways)
bronchioles and alveoli
3
From: Heyder J. Proc Am Thorac Soc. 2004;1:315.
11. Particle Deposition
• Larger particles (> PM10)
deposit in the upper
respiratory tract
• Inhalable particles (< PM10)
penetrate into lungs
• Some particles (e.g.,
less than 0.1 um) may
enter bloodstream
• Particles may react,
accumulate, be cleared
or absorbed
14. Health Impact of Diesel Emissions
Data from 2010 Clean Air Task Force
15. Does exhaust really matter to
people with asthma?
A study examined the 1996 summer Olympic games in Atlanta
To reduce traffic for the games:
• Around-the-clock public transportation was provided
• 1,000 buses added to the existing fleet
• Downtown city streets were closed to private cars
• Downtown delivery schedules altered to ease morning rush hour
• Allowed flexible work schedules and telecommuting
These changes resulted in marked declines in ozone and other air
pollutants known to trigger asthma exacerbations.
Friedman MS, et al. JAMA. 2001;285:897-905
16. Results for people with asthma
• When compared to pre-Olympics data, the
frequency of asthma events (emergency room
and/or hospitalizations) decreased by
–
–
–
–
42% (Georgia Medicaid claims)
44% (Health Maintenance Organization data)
11% (data from two Pediatric Emergency Depts)
19% (data from the Georgia Hospital Discharge
Database)
• So, reducing pollutants and ozone reduced the
burden of asthma!
Friedman MS, et al. JAMA. 2001;285:897-905
17. Health Recommendations
• Check Air Quality Daily:
– 1-866-DAILY AIR
– (1-866-324-5924)
– www.epa.gov/airnow
– Orange level means air quality is
bad for sensitive groups including
older adults, all children, and
people with respiratory illness.
• On bad air quality days:
– Stay indoors
– Do not exercise outside
22. Education is the key!
• Drivers given DNR and EPA literature
showing effects of idling.
• Drivers given window clings to remind them
to shut off vehicles.
• Bus drivers given magnets to remind them
to shut off vehicles.
• Drivers complying receive a magic school
bus key ring as a thank you.

28. Diesel Oxidation Catalyst Required
On 2011 And Newer Buses
*
1. Beginning with the 2011-12 school year, all 2011 model school buses shall have
EPA verified crankcase filter systems and diesel oxidation catalyst systems.
2. Beginning with the 2010-2011 school year contractors will be required to install the
MPS Automatic Vehicle Locator (“AVL”) system on buses designated by MPS.
29. MPS Bus Contract Anti-Idling
Language
The purpose of this policy is to implement current US EPA standards by eliminating all
unnecessary idling of contracted school buses. This policy applies to the operation of all
contracted school buses.
1. When school bus drivers arrive at loading or unloading areas to drop off or pick up
passengers, they should turn off their buses as soon as possible to eliminate idling time
and reduce harmful emissions. The school bus should not be restarted until it is ready
to depart and there is a clear path to exit the pick-up area. Exceptions include
conditions that would compromise passenger safety, such as:
a. Extreme weather conditions
b. Idling in traffic
2. Limit the idling time during early morning warm-up to what is recommended by the
manufacturer (generally 3-5 minutes) in all but the coldest weather.
3. In colder weather, schools will be directed to provide a space inside the school where
bus drivers who arrive early can wait.
4. In colder weather, if the warmth of the bus is an issue, idling is to be at a very minimum
and occur outside the school zone. The “Warmed” school bus is to enter the school
zone as close to pick-up time as possible to maintain warmth and then shut down.
5. Bidders must have a detailed strategy to train drivers on this policy, including anti-idling
procedures in driver training materials. Anti-idling signage will be posted at all bus
company locations.
6. Bidders shall conduct regular on-site inspections of school sites to ensure procedures
are followed. Bidders shall take immediate action to rectify the occurrence.

63. Healthy Transportation
Studies show that more than 70% of ambient air
pollution comes from diesel emissions alone.
– Diesel particulates are dangerous because they are so tiny, and can
lodge into the deepest areas of human lungs.
– Children, in particular, are susceptible because they breathe 50
percent more air per pound of body weight than adults.
Propane powered buses emit virtually zero particulate
matter.
– In essence, this is a 100% decrease in unhealthy particulate
emissions when compared to diesel school buses.

February 1, 2013
-13 air temperature, -25 wind chill in Minneapolis
Chaska, MN: buses started at 5:00am to begin 6:00am driver check-in
Two diesels were no starts and were plugged in over night
All Propane Units started right up and did not need to be plugged in
Within ten minutes all propane units were starting to heat and take the extreme cold out of
the air; nearly all of the diesel still were below zero due to the cold.
By 7:30am some diesels were warmed up; plenty other diesels you could still see the
breath in the air.
“Propane unit drivers were so warm they were able to shed jackets and wear a sweater, or
even a short sleeve shirt with “house temperatures”
“Many old school bus drivers that were around in the 60’s and 70’s that used propane units
then experienced buses freezing up in the winter time or hard starts. With today’s propane
converted equipment we have experienced none of that. Everything has been easy
starting, fast heating, and few issues if any.”

“With today’s tight school budgets, using a transportation fuel that saves
taxpayers money, keeps the environment clean, and keeps jobs within our
national borders is a win-win for everyone. Plus, our drivers love how quiet the
propane buses perform.”
–
“Before tax credits, we pay nearly half the price of diesel for propane, cutting our
fuel expenditures by more than 50%. So far we’ve saved $10,000 on the five
Blue Bird buses alone.”
–
Kevin Neafie (Director of Transportation, Tippecanoe School Corp IN)
“In their first year of operation, these propane autogas school buses (81) are
expected to save $500,000 to $700,000 in fuel and maintenance costs over
their diesel counterparts.”
–
William Schofield (Superintendent, Hall County Schools GA)
Mark Elias (Area General Manager, First Student OR)
We are saving $0.37 per mile in operating costs; any-one who works with
