Typical installations underground, would include Type USE in service lateral in a Schedule 80 PVC, Sunlight resistant and with insulated bushing or bell end to protect from abrasion at end below at elbow in the ground and the "cover" is dictated by the location, as previously mentioned here.
2 feet is best and the Utility may have some requirements too.
If the PVC was continuous from the supply XFMR to the Meter Socket enclosure we need to install an expansion fitting, see 300.5(F).
Will look for some pictures and diagrams for later posting, on the way right now to California for the next 3 weeks.
