I count three stations currently running illegally, that is dead air without station ID's and presumably without any operator controls over them (unless there is an engineer at each transmitter site). Aren't full power stations required to have failsafe controls at transmitters at remote sites? Failsafe meaning when dead air or loss of transmitter control is detected for a certain amount of time, the transmitter shuts off. Will there be fines?
I would say there is zero chance of fines, at least from the FCC.
Dead air, while not a good idea, isn't illegal.
A station operating attended (with personnel either at the transmitter or, more likely, at a remote control point) must have the ability to turn the transmitter off within 3 minutes. Stations operating unattended must be wired such that the transmitter is automatically shut down within three minutes if it is operating in such a way "...that is likely to significantly disrupt
the operation of other stations," Examples include operation on the wrong antenna pattern (only likely at AM stations).
Operation otherwise at variation with the station license or FCC rules requires that the transmitter be shut down within three hours. Strangely, operation at excessive power is specified as an example in this paragraph -- you would think it would be a condition that could "...significantly disrupt the operation of other stations." and would require a 3-minute shutdown.
It is very unlikely any station on this list besides KOMO(AM) could end up in a mode that would interfere with other stations. There is a remote possibility of a frequency drift but that's unbelievably rare. Their transmitters, even if turned all the way up, are not capable of running enough power to interfere. KOMO AM is the only station on the list that *has* more than one antenna pattern mode.

If the STLs were out, I suppose the stations would probably lack the ability to run a station identification. So if the outage ran across the top of an hour, there would likely be a violation. Arguably, however, violation of the legal ID rule would fall under paragraph (d) of 73.1350, and the station could continue operation for three hours without an ID.
Many stations have used the failure of the studio-transmitter link as an interlock to the transmitter. It certainly serves as an easy means of compliance with paragraph (b)(2) of 73.1350. It's not the only way though; it's not mandatory.
