Trillium CNG Inks Deal With Monterey Regional Waste Management District in Calif.

CHICAGO, IL--(Marketwired - Feb 16, 2015) - Trillium CNG™, a business unit of Integrys Energy Group, Inc. (NYSE: TEG) has signed a letter of agreement with the Monterey Regional Waste Management District in California to build, own and operate a new compressed natural gas (CNG) refueling station to power the district's CNG refuse trucks. The station will be built at the Monterey Regional Environmental Park located at 14201 Del Monte Boulevard in Marina, Calif.

By mid-2016, the District will extrude the methane gas produced at the Monterey Peninsula Landfill, a nearby sanitary facility, and convert the recovered natural gas into CNG to power their fleet. Trucks will begin and end the day at the site. "It's really sort of a perfect closed loop resulting in negative carbon impact," said Tim Flanagan, the district's assistant general manager.

"We are excited to partner with the Monterey Regional Waste Management District in this innovative and environmentally-advanced project," said Mary Boettcher, president of Trillium. "We congratulate the District in advancing their nationally recognized solid waste management and resource recovery efforts."

The new CNG station will feature time-fill posts to handle the district's 50 CNG refuse trucks today as well as a fast-fill dispenser that can be made available to other local City and County fleets. However, it will be expandable to accommodate up to 100 CNG vehicles as their fleet is fully converted.

Groundbreaking is scheduled in April with completion targeted for the end of July.
