Why would a 30A-250V outlet still have power with breaker off?

It sounds like the breaker is unserviceable. Seeing as it supplies 240 volt outlet it must be a two pole breaker. If it is a single handle two pole breaker then one pole set inside the breaker is not disconnecting one of the lines. If it is supplied from two single pole breakers that has a common tie, the common tie might be loose and does not shut off both poles when thrown to the off position. If there is no common tie then both breakers must be turned off to interrupt the 240 volt supply.

Slam shut valve?

Slam Shut-off valve is installed immediately after the filter & prior to the Regulator.
