Bonding without sepearte EGC in subpanel

[jzimmer238]

My home was built in 1994. The utility pole is 70' from my house. At the main panel at the pole the ground and neutral are bonded. A 150A breaker feeds a subpanel at the house through 3-4/0 AL conductors running underground without conduit. At the supanel in the house the the neutral and ground are bonded. A #4 bare copper wire runs from the neutral bar to a ground electrode. Should the ground and neutral be isolated? Does a seperate EGC need to be ran back to the main panel.
