Just a guess...

But, I would think those being STV'd will be notified well in advance of the monthly bid. Think about it. They'll know in a couple weeks, just how short they are of permanent crews.

The voluntary STV's will probably be bid on like SIBA is now. And, that's 7 weeks or so, in advance of the 1st monthly bid closing.

However, I'm just trying to use logic...What was I thinking???
