LYNNFIELD, MA - GreenMan Technologies, Inc., announced  that its American Power Group, Inc. subsidiary ("APG") has signed an EPA Test Vehicle Exemption agreement with Paper Transport, Inc. to launch an over-the-road test of APG's dual fuel system. The EPA exemption will allow APG to gather critical performance and emissions data on a pre-dual fuel and post-dual fuel basis to support recently announced EPA aftermarket approval requirements.

Paper Transport, Inc. is a regional fleet operator headquartered in Green Bay, Wis., with more than 280 power units delivering goods and services to customers in dedicated and regional configurations. Paper Transport Inc. has regional fleets in the Upper-Midwest, Southeast, and the Central Plains as well as Intermodal drayage operations and a logistics offering.

Lyle Jensen, GreenMan's President and Chief Executive Officer stated, "On April 8, 2011, the EPA formally amended the alternative fuel aftermarket conversion regulations for light medium, and heavy duty vehicles, which opens the market for properly engineered conversion systems to literally millions of diesel trucks on the road today. The positive performance attributes of our APG V-3000 Dual Fuel System are well positioned to take advantage of this opportunity."

APG's dual fuel system converts diesel engines and diesel generators to function more efficiently and at a lower operating cost (average net fuel cost savings of 25-35 percent) by seamlessly displacing 40-60 percent of the normal diesel fuel consumption with CNG, LNG, well-head gas, or bio-methane. APG's system is non-invasive to the OEM engine and operates within all OEM performance controls with the flexibility to return to 100-percent diesel operation at any time. APG's dual fuel conversion and emissions reduction systems can help users achieve their sustainability goals through lower carbon monoxide, nitrogen oxide, and particulate matter emissions. In addition, the introduction of natural gas through APG's dual fuel system does not impact diesel engine power or pulling torque and will assist in extending the engine's oil life as natural gas is a cleaner burning fuel compared to diesel.

Jensen continued, "Paper Transport is a regional pioneer in the promotion of natural gas as a transportation fuel and currently operates seven dedicated natural gas trucks. Paper Transport represents an ideal opportunity for us because they are already operating natural gas vehicles and are looking for a cost effective retrofit solution for a large portion of their remaining diesel vehicles. APG's Dual Fuel System offers a very robust solution at a price point that allows customers to retrofit multiple existing diesel engines for the cost of one dedicated natural gas engine."

He added, "We can help customers like Paper Transport to maximize their current fleet investment by retrofitting existing diesel engines with APG's Dual Fuel System and realizing the economic and environmental benefits from day one. The initial vehicle to be tested for Paper Transport will be a 2009 Freightliner Cascadia with a 14.8L Detroit Diesel DD15 Series engine."

Paper Transport, Inc.'s President, Jeff Shefchik stated, "Paper Transport is excited to further our position as the leader in natural gas vehicle operations by working with APG and their dual fuel technology. We are committed to offering our customers economical and environmentally friendly transportation solutions. Our agreement to move forward with APG expands our commitment to converting more of our fuel consumption to natural gas."
