Where does our Natural Gas come from ?

Renewable Sources• Landfills• Dairy Farms• Food Waste

North America Gas Fields• 29 states have reserves• Large reserves off shore

Imports• Russia has 30% of world

Casella’s Path to CNG Power

2006 – Rise in fuel prices and new sustainability objectivesprecipitated a search for alternatives.

2007 – short dance with HD hybrids, investigated fuelcatalysts, some bio-fuels (still used), propane, LNG.

2008 - 2009 –strategic plan, budget, project plan, time line

2010 – first station on line, first 3 trucks purchased,Williston, Vermont.

2011 – 2013 3 more stations in NY; 30 trucks, NY & VT

• Produces less CO, VOCs, NOX and PM than gasoline or diesel,equates to 23 - 25% less GHG emissions

• Simpler solution amid forever tightening EPA requirements

• Non hazardous, will not pollute the ground or water

• 15% quieter than diesel trucks (happier drivers, customers, andneighbors)

• For RNG the decomposed waste can be traced back to the organicsource that replenished it; leads to even higher GHG emissionreductions over carbon life cycle

Environmental Considerations

• Provides positive investment returns andreduced fuel cost volatility. Domestic!

• Maintenance about equal to diesel and canbe lower. No DPF or SCR, installed 3 waycatalyst only.

• Natural gas delivered is one-half the cost ofdiesel fuel

• Natural gas prices historically less volatileand reserves estimated at 120 years??

Business and Operating

Casella’s first CNG front load truck

• Autocar with Cummins-Westport ISL G CNG engine with Agility 63 DGECNG Tank, in service in April 18, 2011.

CNG makes economic sense for waste trucks

Equipment costs

• CNG trucks cost roughly $40-50k more than a diesel truck (fuel cylindersand system)

• Chassis cost is equal

• CNG time fill fueling station costs $695k to $990k

• Federal and some state grant money available.

Transportation Petroleum Dependence

GLOBAL COMPETITION FOR OIL INCREASING

• Time fill station - $600k – $850k

• CNG waste vehicle incremental - $35k - $40k

• Maintenance facility modifications - $50k - $90k

• Training, maintenance and ops - $10k

Implementation Costs

Decoupling of natural gas and oil due to the “Shale Gale”

Gap Analysis

1) Station load profile, gas and electricity vs demand, time fill fast fill?

2) Adequate gas supply

3) Emergency procedures, emergency power

4) Shop upgrade

5) Vehicle specifications

6) Vehicle fuel capacity, range anxiety!

7) Mileage penalty is a reality, use +- 10%

8) O&M

9) Sighting/permitting

10) CAPEX

11) Training

12) Fueling redundancy26
