Not at this time. It did take us nine months to get from our initial ask to getting our national emissions mark, which I find was quite lengthy. That being said, it's our first time around the bus.
Based on conversations I had with the department yesterday, we are still waiting for managerial approval to potentially expedite our engine C-U letter, which is incredible news. That being said, no firm timeline has been provided.
In terms of making this amendment, I have never really changed a regulation before, so I'm looking forward to your thoughts and concerns there.
