Navistar files second suit against EPA; SCR proponent calls it ‘frivolous’

Navistar, alleging that operators can too easily “defeat” SCR systems, thus rendering EPA emissions-reduction rules “irrelevant,” has filed a second lawsuit against EPA.

The lawsuit, filed July 5 with the U.S. District Court for the District of Columbia, alleges that Navistar, a contractor the truck maker hired, and the California Air Resources Board (CARB), found that when drivers don’t keep diesel exhaust fluid (DEF) topped off, it makes EPA’s SCR rule “irrelevant,” because it allows nitrogen oxide emission levels to “skyrocket.”

“EPA has not tested SCR-equipped engines, nor has EPA required them to be tested, in the manner that reflects the way that EPA has authorized them to be driven on the highway,” the lawsuit states.

The suit also accuses EPA Director Lisa Jackson of not doing her duty to enforce the Clean Air Act and says the agency isn’t upholding its mission of protecting public health.

EPA’s first limits on nitrogen oxides emissions from large commercial trucks started in 2001, with the most recent mandated for last year.

I don't understand the lawsuit, isn't this kinda like cutting your own nose of just to spite your face?
 
What really gets me is they are still dealing with what comes out of the exhaust pipe, rather than getting the engine to be more efficient and pollute less to begin with.

The automotive manufacturers did this years ago, and today's gasoline engines are mach more efficient than they used to be (although they still have a long ways to go toward near perfect thermal efficiency).

If the diesel engine manufacturers would work more toward improving how combustion takes place inside the engine, there would be less pollutants to deal with in the tailpipe.
 
Yep keep voting Democrat N they'll let the treehuggers N sierra club run your operations tgmhrough lobbying and REGULATE YOU INTO BANKRUPTCY

To be fair the larger fleets likes of swift werner JBHUNT SCHNIDER EGGLAND and the like are also lobbying for these type of arcane regulations to drive O/Os and smaller carriers out of buisness knowing they cannot bear the costs the BIG FLEETS CAN
 
The air and water is. Much cleaner today than it was decades ago we the small guy are targets of advocacy groups and politicians while their billionaire ceo donors get exemptions for their firms that pollute more in a day than my truck does all years cause they have power through money

WE the little guy can't compete with that furthermore these fancy emissions controls have. Driven truck costs sky high
LOWER. FUEL MILEAGE AND MORE REPAIRS DO TO KINKS

WHEN I was a kid trucks blew big acrid clouds of smoke
NOWADAYS WE GOT THAT DOWN TO A FINE.BROWN MIST AND THE ADVOCATES STILL AINT HAPPY
 
Democrats and their advocacy groups are also pushing EOBRs and stricter HOS rules as well as governed engine speeds for all similar to ONTARIOs laws

So when you go to the polls if you see a D next to the name don't vote for that guy
