Tell the EPA to Close this Truck-Size Loophole

Ask the Environmental Protection Agency to keep the cap on polluting glider trucks.

All new trucks sold in the U.S. need to meet pollution requirements. But on the day Scott Pruitt resigned from the Environmental Protection Agency, he handed a big giveaway to some of the biggest polluters on the road.

Glider kits allow dirty, old engines to be sold in new semi truck bodies. They save shipping companies money, but they cost us all by polluting up to 55 percent more. That’s why the EPA planned to place a sales cap on manufacturers of 300 glider kits per year. Annually, the cap could prevent 350 to 1,600 premature deaths from lung cancer and other causes.

But Pruitt killed the plan to enforce the cap, creating a giant loophole for dirty engines.  Environmental groups are suing the EPA to reverse direction, and although the courts have placed a stay on Pruitt’s plan, the EPA could still go either way.

This week, act on climate by asking the EPA to keep the cap. In 2015, about 10,000 glider kits were sold in the United States, and without regulation the numbers are expected to return to that level.

To the Office of Transportation and Air Quality,

I’m writing to ask the Environmental Protection Agency to enforce the cap on the number of glider kits sold in the United States. The rule limiting manufacturers to 300 kits per year is a sensible measure to improve air quality and reduce the number of health risks associated with heavily polluting truck engines.
