THE LPI

FUELTANK

MAJOR ISSUES TO CONSIDER•Pilot a cutting edge program• Wanted to try an alternate fuel to be a part of the Green Initiative• Pending new regulations, additives etc. were changing for 2010• Battery powered electric too expensive•Clean burning fuel

o Minimal impact to the environment•EPA requirements for emissions were met with Propane power• Capacity size was not affected• Quiet ride

Planning for Propane•Decided to look at 3 types of Routes to measure efficiency.

oBus 1 - Long Distance Route to neighboring County – Few stops oBus 2 - Inter-city run. Congested traffic/Frequent stops oBus 3 - A1A Corridor / Long Run – Moderate to Frequent stops

•Found that buses would need to refuel daily as each could travel for approximately 1 ½ days on a tank of fuel.

•Results were satisfactory overall, with the exception of miles per gallon.

•Fuel for buses is significantly less expensive.

PROS AND CONS OFPROPANE ENGINES

PROS• LOWER FUEL COST• NO ROAD TAXES• LESS EMISSIONS• SMALLER CARBON FOOT PRINT• LESS GREEN HOUSE GASES• POSSIBLE GRANT MONEY AVAILABLE• PROJECTING LONGER BRAKE LIFE DUE

TO LESS WEIGHT• EXCEEDS EPA REGULATIONS WITH NO

CHANGE• NO SHELF LIFE WITH PROPANE• TAX REBATES ON EACH BUS

PURCHASED• FUEL TANK REBATES CURRENTLY

AVAILABLE AT $.50/GALLON OF LP• MINIMAL INFRASTRUCTURE COST AND

SET UP

CONS• DISTANCE BUS CAN TRAVEL BETWEEN

FILL-UPS• LOWER MILES PER GALLON OF FUEL• OPTION CHARGE FROM

MANUFACTURER (MAY BE RETURNED AS A TAX CREDIT)

Propane Fuel Rebates

• Congress Has Authorized an Alternative Fuel Rebate of $.50 per Gallon for Propane if Facility Has Their Own Fueling Station

• Must Register with IRS – Form 637• File IRS Form 4136 Annually

Comparison of Engine RelatedRepairs and Maintenance

SURVEY WAS CONDUCTED WITH:• Sixteen 2009 Bluebird “Vision” buses• All were 71 passenger capacity• Comparison was done after 17 months of service• 13 buses were powered by Cummins Diesel Engines• 3 buses were powered by General Motors Propane Engines

SURVEY RESULTS ON ENGINE RELATED ISSUES:• Average cost per bus (includes oil and filter)

• Diesel Powered: $118.95• Propane Powered: $102.58

Number of Road Service Calls• Diesel Powered: 4• Propane Powered: 0
