New CNG Station in Oak Creek, Wisconsin

Trillium CNG

Tolleson, AZ – EVO CNG and its joint venture partner, Trillium CNGTM are pleased to announce the opening of a new compressed natural gas (CNG) fueling station located at 7155 South First Street, Oak Creek, Wisconsin.

The station’s anchor tenant, Sheehy Mail Contractors, operates ten Freightliner Cascadia tractors with Cummins-Westport ISX G engines, and is planning to add more this summer.

The station is open to the public 24 hours a day, seven days a week. It has four dispensers and features Trillium CNG’s proprietary fast-fill technology. The station has been designed to accommodate Class 8 tractors and trailers, as well as smaller vehicles.

“EVO CNG is extremely excited for the opportunity to work with Sheehy Mail as they move into the clean fuel arena,” said Danny Cuzick, President of EVO CNG.  “We look forward to the future growth of clean natural gas stations providing Sheehy Mail to demonstrate their leadership as they expand their green fleet.  EVO CNG is proud to partner with Trillium CNG in the development of these stations.”

“We took delivery of our ten 12 Liter CNG Cascadias in July of last year”, said John Sheehy, President of Sheehy Mail Contractors in Waterloo, WI.” Since then we have driven 700,000 miles with these trucks in one of the toughest winters on record. The CNG fleet performed as well as the Diesel equipment in these severe conditions. Incorporating the clean burning, American sourced natural gas into our fleet is a priority for the US Postal Service, as well as our freight shippers, and we are proud to be a part of the pilot program with EVO CNG in the Milwaukee area. We are looking forward to increasing our CNG fleet this summer and have plans to expand our natural gas fueling needs to Iowa, Illinois and Indiana in the coming months”.

“We strongly support Sheehy Mail Contractor’s decision to convert their fleet to compressed natural gas (CNG) because of the compelling economic and environmental benefits”, said Mary Boettcher, Trillium CNG president. “It is a privilege to be working with both EVO CNG and Sheehy Mail Contractors who are committed to natural gas as a fuel source to power the nation’s heavy-duty fleets.”
