Irving Oil's travel plaza in Kittery, Maine is now equipped with a diesel exhaust fluid pump, making it the most northern DEF pump dispenser in New England.

Currently, this Irving location offers the only DEF pump in Northern New England, which is made up of Maine, Vermont and New Hampshire. 
The location, by the U.S. Route 1 bypass, has a combination pump designed to dispense DEF and diesel fuel in one spot and in one transaction.

"Installing a combo-pump in the diesel fueling lane saves drivers time and eliminates the hassle of having to reposition the truck or fill up the DEF tank using portable jugs," says Harry Hadiaris, general manager of Irving Oil Marketing. "In just one transaction, our customers can fill up on both DEF and diesel." 

Irving is planning to expand its DEF offer to other parts of its network in the future.

DEF is an ammonia-based solution used to clean exhaust and reduce emissions from diesel vehicles. Since Jan. 1, 2010, the Environmental Protection Agency's tailpipe emissions standards have required heavy-duty highway trucks and buses manufactured after 2009 to meet more stringent emissions limits for NOx and particulate matter.

Most heavy-duty vehicle manufacturers have added selective catalytic reduction to their exhaust system design to meet these tougher standards. The SCR technology uses DEF to chemically reduce NOx, or smog-creating emissions, to near zero.
