A
prior thread discussed the subject of new California CARB (California Air Resources Board) requirements for OTR diesel vehicles.
We received a letter informing us that our DP coach, being over 14,000lbs GVW, needed to be registered with CARB and a fee paid. I went ahead and did this and, because of timing, our coach was considered in compliance until Feb, 2025. Meanwhile, my searches, including on the CARB web site, couldn't find a CARB testing station within several hundred miles.
A month or so ago a friend in the same predicament gave me a heads-up to a local CARB testing station, just a couple of miles from here, and a mile or so from where we store the coach.
I started getting CARB notices that the coach needed to be tested, and meanwhile was considered non-compliant. I tried calling CARB to get some relief on the deadline due to my protracted lack of mobility after knee replacement; I received an automated mesage saying "Your call is really important to us; There are 44 callers in line ahead of you".
We finally got the coach tested today, albeit after the deadline, and it passed with flying colors. The first hurdle was the need to find the Cummins emissions tag. The test guy needed access to the top of the engine, which I provided via the floor hatches in the bedroom and closet. No luck, so he crawled under the coach, and again no luck, then accessed the engine via the rear engine bay doors. After some poking and prodding he found the tag on the front/topside of the engine, hidden beneath a wire harness. A snip of some wire ties and the harness could be moved far enough to view, clean and photograph the tag. Without this, it was an automatic fail.
The guy suggested we leave the coach for him to run the tests. He called me a couple of hours later to let me know he was done.
Next was filing the test results; Unlike the CA smog testing for gas vehicles that sends test results real-time to the DMV, CARB test results have to be printed, scanned, and emailed by the testing facility. So, until a human receives and reads the results, our coach is still "non-compliant" in their database (I just checked).
Test and filing costs $309, paid up front, more than 3X what I pay for smog testing on our gas vehicles.
