This is not that un-common.
There are STAs issued quite often for operations in and around multiple amateur bands.

Hey Guys,
?
I know you're not in Southern California however, we've recently had the FCC issue Experimental Licenses to a company that is testing a Radar System with 10KW ERP causing interference to several Amateur Repeaters in the Los Angeles basin. The FCC Enforcement Bureau from the Cerritos Office was successful to get them off the air as we are Primary on the band.
?
But, now the same company has received a Experimental License to conduct the same testing at the Yuma, Arizona proving grounds with an ERP of 7KW which will cause interference to 220 repeaters from Arizona to southern mountains bordering Imperial, San Diego, Riverside and even San Bernardino County. This is a serious threat to our spectrum and we need to protect it. If you were around during the UPS spectrum grab of 220-222MHz you'll know what I mean.
?
I am the President of the 220 Spectrum Management Association which is the Radio Amateur organization who coordinates repeater channels in Southern California (). Please check this out, if this can happen in LA, it can and left uncheck will anywhere else.
