CARB blasts EPA over diesel trucks
December 4, 2017
• State says EPA’s move will let high-polluting, older trucks on roads
• CARB opposes repeal of rule limiting “glider” kits for big rigs
California is formally opposing a federal move to loosen air pollution controls on diesel trucks.
The state says decades of clean air progress stand to be reversed if the U.S. EPA opts to repeal its rule on limiting production of so-called “glider kits,” says Steve Cliff, deputy executive officer of the California Air Resources Board.
A “glider kit” is a new truck chassis and cab that includes a refurbished diesel engine and power train. In almost every case, these kits include much older so-called “pre-emission” engines from 10, 15 and up to 20 years ago. These engines evade current diesel-powered truck tailpipe standards. As a result, compared to current clean trucks, CARB says, they emit massive amounts of smog-forming pollution and toxic carcinogenic soot, directly impacting public health.
“If you enjoy driving behind a truck belching clouds of black carcinogenic smoke, you can thank EPA for putting many more of them on the roads, rather than cleaner modern models,” says CARB Chairman Mary Nichols. “This illegal effort by EPA will open the floodgates to allow unlimited numbers of old and dirty trucks to pour onto our streets and highways masquerading as brand new clean trucks.”
