2 Protecting Our Blue Planet We believe in the preservation of a Blue Planet... a cleaner, safer and healthier world where people thrive not just for today, but generations to come. We are guardians of our environment and have a responsibility to regenerate our planet with the materials we are entrusted to handle every day by driving increased recycling, generating renewable energy and helping our customers be more resourceful. We must lead by example, working diligently to improve our relationship with the environment and society through decreased vehicle emissions, innovative landfill technologies, use of renewable energy, community engagement and employee growth opportunities. This is not a fleeting cause. It is the foundation of our future, and the very heart of who we are as we work every day to protect our Blue Planet.

5 Why CNG? 1. It s the right thing to do and it s environmentally responsible 2. It s cleaner emissions are lower and increasingly alternative fuels are mandated 3. It s local natural gas is abundantly available from North American sources 4. It s cheaper current natural gas costs are lower than diesel 5. It s quieter customers like less noise

9 Natural Gas vs. Diesel (Forward Curves) Despite updated EIA projections, the current spread between diesel and natural gas continues to make economic sense. $/DGE $4.00 $3.50 $3.00 $2.50 $2.00 $1.50 $1.00 $0.50 $- '14 '15 '16 '17 '18 '19 '20 '21 '22 '23 '24 CNG $/DGE *EIA STEO Diesel *EIA STEO Spread *EIA STEO Source: Energy Information Administration ( EIA ), 20 YR Annual Price Projection April 2015 Update 6

gas continues to make economic sense. $/DGE $4.00 $3.50 $3.00 $2.50 $2.00 $1.50 $1.00 $0.

10 Site Development Opportunities Our primary focus continues to be sites with more than 50 trucks. There are still significant numbers of site/truck candidates for CNG.

11 CNG Challenges CNG conversion is not a one size fits all solution. Depending on site characteristics, CNG may not be practical. Engine size, payload Location, Location, Location Site feasibility Access to adequate gas and power Public infrastructure Shop Improvements Permitting & Zoning
