RNG Math• Four Facilities – NY, OH, KS, OK• Combined Production Capacity

– 11,000 MMBtu/Day

• MMBtu to GGE of CNG = 12.98*• 142,780 GGE per day• Annually displaces 52 million gallons of gasoline• Annual reduction of 124 million tons of CO2

emissions* from gasoline

* Based on USEPA conversion factors

16

RNG Math• Seneca New York Facility• Production Capacity

– 2,000 MMBtu/Day• 25,960 GGE per day• The average convenience store sells 4,000 gallons of

gasoline per day *• 6 ½ average stations to sell output from Seneca based on

gasoline sales• Access to national pipeline network mandatory to move

production to markets* Based on NACS bulletin
