Connecticut Transit (CT) will receive 400,000 of ultra low sulfur diesel fuel from Sprague for the next year. The delivery makes CT compliant with 2006 EPA mandates nearly five years early. The clean diesel fuel, containing 95% less sulfur than conventional diesel, has been delivered to the Stamford facility for its 48 buses since September 1. "Ultra low sulfur diesel fuel gave us the most cost-efficient way to reduce emissions in our fleet," said Steve Warren, assistant general manager of CT. "Changing to [the fuel] required no major changes to our operations, infrastructure or labor force." The 2006 EPA standards mandate that the sulfur content in diesel fuel be reduced from 500 to 15 parts per million.
