I really hate this post-truth timeline. The lying is so blatant, and so everywhere.

4. Regarding emissions, this is straight from the horse's mouth

https://ww2.arb.ca.gov/truck-bus-regulation-basics-exemptions-truckstop

Diesel trucks and buses with a gross vehicle weight rating(GVWR) that are greater than 14,000 pounds (lbs), must reduce exhaust emissions by meeting particulate matter (PM) filter requirements and upgrading to a 2010 or newer engine model year (EMY).

The Regulation does not apply to:

Public Agency and Utility Vehicles (Not Federal)

Since fire departments are non-federal public agencies, the State of California wouldn't be able to stop them from coming in and helping. Besides...uhh...2010 (the year selective catalytic reduction first became required on diesel engines) was fifteen years ago. I suspect the State of Oregon has enough fire apparatus that's no older than 2010 that they could have sent that equipment to California and not worried about the ARB's regulation if it applied to fire apparatus in the first place - which it does not.
