  1. Criteria for Casella AFV Initiative• Business case positive. Pay for itself.• Does it meet Casella sustainability profile? Improved emissions.• Likelihood of successful operation and maintenance. Proven. Casella’s First CNG Collection Vehicle

  2. Time Line • 2007 – Initiated search for best AFV solution, purchased International Hybrid/Electric food waste truck, March demoed 2007 Autocar CNG truck (Cummins ISL Gas+) • 2008 – Applied for and received EPA grant through Granite State Clean Cities in NH for our Salem location. Site and other issues killed project. Shifted focus to All Cycle and Vermont Gas Systems. • 2009 - Tim Lyons of Vt Gas took an interest. Casella applied for DERA EPA grant for vehicle funding, received $205,000.00 for three trucks. • 2010 - Casella funded and built with help from Vermont Gas Systems and AVSG first CNG time fill station in Vermont for 6 refuse trucks, on line December. • 2011 – Purchasing 4 more trucks and have added infrastructure to fuel a total of 13 vehicles at All Cycle Also adding at least 6 trucks and building 2 more time fill stations in Geneva and Moreau, NY.

  3. The Dilemma:The transportation sector is “addicted” to liquid petroleum fuels

  4. Per Barrel Oil Prices 1973 thru 2009Volatility is the rule not the exception Approximate March 2011 price $100.00

  5. 35 gallons per day, 250 route days per year times 1.95= $17,000 savings per year per vehicle Ultimate build out at All Cycle Waste 13 trucks: Savings $221,000/year Business CaseDiesel Gallon Equivalent, (DGE) =136 cft cng = 130,000 btu’s approx 1 gallon diesel

  6. Business Case (cont) • Maintenance cost equal to or less than diesel and gas • No diesel particulate filter (DPF) or selective catalytic reduction (SCR) or maintenance associated. Installed 3 way catalyst, no maintenance. • Federal tax credits: .50/GGE and 50% of the cost of the fueling station or $30,000 whichever is less. • Natural gas reserves of at least 120 years • Federal and some state grant money available

  7. Truck Technology - Engines 2010 Diesel Exhaust Treatment 2010 Natural Gas Exhaust Treatment Natural Gas Benefits No Diesel particulate filter No Diesel emission fluid Increased operator visibility Less complexity 11

  8. Improved Emissions-Sustainability Replacing a diesel vehicle with a CNG or LNG vehicle provides the following reductions in exhaust emissions: • 70-90% carbon monoxide (CO) • 50-75% organics (NMOG) • 75-95% nitrous oxides (NOx) • 20-30% carbon dioxide • Or 45,000 lbs per year less CO2e per truck

  9. Sustainability (cont) • 15-20% quieter that diesel • Fuel is safer- ignition temperature 1100 to 1300 F vs. 400 to 500 F for diesel - lighter than air - does not pool • Will meet EPA’s standards without complicated exhaust after treatment for at least the next 10 years

  10. Natural Gas Engine Technology • Cummins-Westport • Joint Venture • ISL G met 2010 emissions standards ahead of schedule • 320 HP @ 1000 ft/lbs torque • Maintenance Free Exhaust System

  11. Hurdles • Gas must be compressed into the tanks to 3600psi • Infrastructure $250k to $1million • Infrastructure is a maintenance item, must be diligent with the care • Fleet is dependant on your fueling system • Trucks have a $30 - $50k incremental cost • CNG, even at 3600psi takes up 4X the volume of diesel • Maintenance shop must have methane detection and ventilation systems if the truck needs to be inside for more than 4 hours • Need access to natural gas!

  12. Casella first “Time Fill” CNG station in Williston, VT Time Fill Post Dispensers – K rail Compressors and Controls Time Fill Post Dispensers – Truck Hookup 16

  13. Time Fill Private CNG Station Time Fill Post Dispensers – K rail Compressors and Controls Time Fill Post Dispensers – In Ground Vocational Energy 17

  14. Truck Storage Tanks Fuel storage tanks are typically incorporated into the refuse body roof..
