The EPA appears to be close to releasing its proposal for medium and heavy-duty truck fuel economy standards. As you may remember, the Obama Administration called for the first-ever standards for large work vehicles earlier this year. According to The New York Times, a spokesperson with the EPA has said that the initial proposal will be out soon. Analysts had expected the numbers to show up this week, but that's looking less and less likely by the hour.

Surprisingly enough, heavy truck manufacturers don't seem to be up in arms over the thought of new fuel economy standards. The New York Times says that the EPA has a history of working closely with big truck makers to reduce emissions, and that this is the next logical step. The EPA and truckmakers say agree that today's diesel rigs crank out 60 times less particulate matter than similar equipment did in 1988. That's thanks in no small part to the EPA's clean trucks program, which is geared toward promoting clean-diesel technology.

The new fuel economy standards are expected to show up in a climate bill that already regulates fuel consumption for passenger cars, light-duty trucks and stationary devices like generators.

60 times reduction in particules....to make a comparison, today's ULSD has 97% less sulfur than before and 90% less particulates. So that's a very small part of the 6000% reduction.

I remember when pretty much all trucks accelerating on the highway would belch heavy smoke and make your eyes water.
