TruStar Energy, in conjunction with Arizona-based D.L. Withers Construction, has been contracted to refurbish the compressed natural gas (CNG) station for the City of Tucson, Ariz., the fueling infrastructure developer announced.

The 20-year-old station’s 3,000 psi fueling system will be upgraded to the newer industry standard of 3,600 psi, and a 90-truck time-fill fueling area will be developed, allowing for more capacity and faster fueling, according to TruStar.

“The existing plant is at the end of its useful life, and city administrators felt it was time to upgrade, given our intention to continue our fleet migration to CNG,” said Brian Conte, senior engineering associate with the City of Tucson. “We currently have 45 CNG transit buses fueling and have plans to expand our refuse collection fleet to 90 trucks, so the station upgrade is essential.”

The station’s existing fast-fueling dispensers, compressors, and dryers will be replaced with new, state-of-the art systems, including Ariel compressors, ANGI-Gilbarco fast-fill dispensers, and a PSB gas dryer, according to TruStar. In addition, a time-fill parking area will be installed to allow for the fueling of the City’s CNG-powered garbage trucks.

Completion of the project is scheduled for the first quarter of 2016, a TruStar official said.
