The conduit on the right is EMT.
The "attachment mast" (for lack of a better term) is GRC.
So Ca Edison is the utility serving this installation, and no, they won't attach the drop to EMT....GRC or IMC is the only approved attachment point.
The entire service could have been relocated to the left 6" or so and avoided the offset around the rain gutter altogether......after all, the feeder to the panel is on the surface.
Strange install, I've never seen anything quite like it
