Tom,

I don't know if uncured epoxy will dissolve the styrofoam, or not.
You would certainly end up with a very rough surface on the interior
of your tank, and this would prevent it from ever being completely
cleaned out.  Worse, I don't think that the epoxy laminate will be
impervious to odors.  I wouldn't recommend a glass laminate, even 
using epoxy resin, for a holding tank.  I, personally, wouldn't use
anything but HD polyethylene.
