2. AGENDA Welcome Opening Remarks Overview of project What was the decision process Major issues to consider Data Analysis Recommendations Project Implementation Questions

7. THE LPI FUEL TANK

9. 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

10. Planning for Propane Decided to look at 3 types of Routes to measure efficiency. o Bus 1 - Long Distance Route to neighboring County – Few stops o Bus 2 - Inter-city run. Congested traffic/Frequent stops o Bus 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.

17. 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

18. Comparison of Engine Related Repairs 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
