Houston goes with Extengine for city fleet

Funded by Texas Emissions Reduction Plan (TERP) grant funds, the purchase represents a major step in Houston's aggressive campaign to reduce diesel emissions from thousands of city-owned vehicles according to Pamela Berger, director, Mayor's Office of Environmental Policy.

"We believe that once the commercial durability of our ADEC system has been verified under either federal EPA or California Air Resources Board protocols, many other cities, fleet operators and engine manufacturers will follow Houston's lead and immediately begin retrofitting ADEC systems in a timely manner," said Extengine president Phillip Roberts.

Under federal law, the eight-county region is required to meet strict new federal air quality standards or risk the loss of federal highway funds and capacity for industrial growth; as well as, the imposition of a Federal Implementation Plan.
