8 CNG Fuel Station Cost $ 2,000,000 Sale of CNG to the General Public = $ 315,000 Sanitation Fuel Savings = $ 540,000 (40% of CNG Fleet) Contract Maintenance of Facility $ 114,000 ROI = 2.69 Years Renewable Fuels Facility Capital Cost $ 12,000,000 Annual Sale (Brown) Natural Gas via Pipeline = $ 1,034, scfm LF 54% Methane = mmbtu / day x 365 x $4.00 est. Henry Hub Price x 0.90% operation efficiency = $ 1,034,026 Annual Sale of RIN s (D3 rating) = $ 3,031, x 365 x D3 RIN x 0.90 % efficiency = $ 3,031,505 10% CNG/LNG Facility + 15% 3 rd Party Fees + EM = $ 774,377 Maintenance of Facility including Utilities $ 784,000 ROI = 4.79 Years

9 Sanitation began operating CNG vehicles in April ) in 2012, 2) in 2013, 45) in 2014, (40 Solid Waste, 5 Senior Citizen Buses) 86) total CNG Conversion Units 29% of Solid Waste Fleet Sanitation operates 280 over the road vehicles Tractor Trailer (Transfer Station) Vehicles 3.1MPG Front End Loader (Commercial) Vehicles 2.1 MPG Rear End Collection (Residential) Vehicles MPG Roll-off Container (Commercial) Vehicles 4.3 MPG Other Solid Waste (Heavy Duty)Vehicles 3.5 to 5.1 MPG Employee Van Shuttles (E-350) 17.6 MPG Supervisor Pick ups (F-250) 12.8 MPG Pool Sedans (Honda Civics) MPG

10 Conversion Cost - 90% is cost for Storage for Heavy Duty Vehicles $15,000 (30 Gallons) $45,000 (60 Gallons) $30,000 (45 Gallons) $60,000 (75 Gallons) Example 1A Residential Rear Loader Private CNG Fueling Station 75 Miles per Collection Day = 18,750 Miles per Year Fuel Cost $ 2.25 Diesel $ 3.75 Difference $ ,750 miles 2.0 MPG = 9,375 x $ 1.50 = $ 14,062 Savings / Year 60 Gallon CNG $45,000 $ 14,062 = 3.20 Years ROI Example 1B Residential Rear Loader Owned CNG Fueling Station 75 Miles per Collection Day = 18,750 Miles per Year Fuel Cost $ 0.75 Diesel $ 3.75 Difference $ ,750 miles 2.0 MPG = 9,375 x $ 3.00 = $ 28,125 Savings / Year 60 Gallon CNG $45,000 $ 28,125 = 1.60 Years ROI Average Depreciation Life 9 Years Storage Tanks Life 20 years
