I have been told on more than one occasion that in Europe our LP tanks are considered HP tanks. Can anyone confirm or deny? Anyone heard something similar?

Do you have a reference to the OSHA/DOT/CGA rules where it relates and states recreational SCUBA tanks and usage specifically? CGA is an association of industry manufacturers and sets standards, not laws.
A quick search of Occupational Safety and Health Administration - Home did not yield any reference to filling recreational scuba tanks. I saw a lot about commercial diving operations.
You are correct that CGA sets standards but those standards are referenced in the CFRs so in affect they are laws.
Here is a good example,look at the section:

As for OSHA I would have do some searching but they are all inter-rated. When it comes to overfilling - OSHA would probably cite for creating a hazardous situation by not following prescribed DOT rules.
I don't think there is a law for or against filling scuba tanks to a specific pressure. The pressure ratings on tanks are manufacturer guaranteed tested pressures. They have to do that in order to comply with DOT regulation. Filling and using scuba tanks is unregulated by law and self-regulated by the industry as far as I know.
So DOT requirements are not law?
I dive double Faber 95's. Recently a cave shop asked us what we wanted filled in the tanks. My new dive buddy said "pump em up to 4k" (I thought he was joking, the shop didn't). Which the shop did. When we got in the water, my computer read 3860psi. Hmmm. 3860psi = 139cu' of air each tank. That's alotta stinkin air in a set of LP tanks. Try that magic with HP tanks. Now granted, I wouldn't ask for 4k fills. But a cold 3600 is very common.
Not at all surprised. Nothing wrong with the advice. I just don't see a strong reason for absolutism, either way.Haha, I know the area and I know OP and people telling to go LP there is certainly some cave country tradition in this.
YES!!!What you might consider is AL80 doubles for wetsuit diving.
YES!!!
