New Post

According to an article found on Dieselnet the California Coast Guard is not happy with the new DPF requirements that ships will have to undergo by the end of the year.

If you have dealt with big trucks and equipment that have these systems you know these vehicles have to stop routinely to undergo ‘regeneration.’ When this happens the engines tend to rev up particularly high (which seems counterintuitive to burning as little fossil fuels as possible for a supposed environmental reason). Because of this the the Coast Guard is concerned with high exhaust temperatures and the fire safety of the vessels in the water.

California has always been the worst for these standards in terms of how strict they are, but even those whos job is to explicitly protect the state are now pushing back. A letter was wrote to Governor Newsom by the American Waterways Operators requesting CARB (California Air Resources Board) reconsiders the DPF requirements.

“Coast Guard regulations do not explicitly address DPF installations onboard commercial vessels,” says the letter to CARB. “Please note that DPFs verified by CARB may not necessarily be accepted by the Coast Guard for installation on inspected commercial vessels.”

Each vessel has to demonstrate federal regulatory compliance, and it is the engine manufacturer’s responsibility to ensure that the engine systems are certified by the US Environmental Protection Agency for marine use and the applicable emission standards. The Coast Guard’s inspectors will not perform emissions tests, the letter says, and therefore the Coast Guard will not enforce California’s DPF regulations.

The above sums up the article but the rest will be my sole opinion. I hope more of this happens. I hope to see more of the industry throw proverbial ‘middle fingers’ to government bodies. People are making decisions so far from the actions and functions of the society they live in. These same people love having a Starbucks on the corner of their street and ignore the delivery truck and every other piece of industrial equipment that helps create their latte. So bravo to the coast guard and I hope more and more organizations(Especially government orgs) push back on the stupidity of emissions control bureaucracy.

On a more positive note if are interested in a cool truck rebuilding project you can check out my latest Youtube video going over the projects I am working on this year: Click here to see that video.

Also if you are interested in becoming more skilled at working on diesel engines or need help with your own equipment whether it be truck, tractor, or construction you can click here to check out the Diesel Den group on Skool.

Have a good weekend and we will write again next week. Thanks,
