7 Biodiesel Deliveries

8 Biodiesel Challenges in a DPW Fleet Fuel Cost Fuel Cost Fueling System Maintenance Fueling System Maintenance Vehicle Maintenance Vehicle Maintenance

9 Biodiesel Challenges in a DPW Fleet Fuel Cost* Fuel Cost* – $2.67 for CNG – $2.85 for Gasoline – $3.45 for E-85 – $3.50 for Diesel – $3.91 for ULS B-20 Diesel $71,750 annual increase $71,750 annual increase –$0.41 X 175,000 * Gallon Equivalent Cost as of April 7, 2008

10 Biodiesel Challenges in a DPW Fleet Fueling System Maintenance Fueling System Maintenance – BioDiesel acts as a detergent agent and actually cleans out tanks. – 35 fuel filter replacements at diesel pumps to date. – Minor material cost increases. – Increased labor costs. – Increased pump down time.

11 Biodiesel Challenges in a DPW Fleet Vehicle Maintenance Vehicle Maintenance -400 fuel filter replacements in vehicles to date. – 35 Fuel tanks have been dropped. $200 to $1,000 each$200 to $1,000 each – Increased material costs. – Increased labor costs. – Manufacturer Warranties B5 vs B20B5 vs B20

12 So Why use Biodiesel in a DPW Fleet? Reduce carbon dioxide emissions by 15%. 1 Reduce carbon dioxide emissions by 15%. 1 Reduce particulate matter emissions by 10%. 1 Reduce particulate matter emissions by 10%. 1 Reduce carbon monoxide by 11%. 1 Reduce carbon monoxide by 11%. 1 Reduce unburned hydrocarbons by 21%. 1 Reduce unburned hydrocarbons by 21%. 1 Reduce life cycle petroleum consumption by 19%. 2 Reduce life cycle petroleum consumption by 19%. 2 1 (Source: U.S. Environmental Protection Agency, A Comprehensive Analysis of Biodiesel Impacts on Exhaust Emissions. 2According to a study by the National Renewable Energy Laboratory.

13 Impact of Nassau County’s Biodiesel DPW Fleet? Based on 175,000 gallons of B20 Biodiesel used in 2007 Nassau Co: reduced CO2 by 555,000 lbs reduced CO2 by 555,000 lbs reduced CO by 18,000 lbs reduced CO by 18,000 lbs reduced PM10 by 100 lbs reduced PM10 by 100 lbs reduced petroleum consumption by 33,000 gallons reduced petroleum consumption by 33,000 gallons
