If the POCO installs it, it's their responsibility, so who cares what they do? Also, they follow the NESC, not the NEC.

Peter we did an entire town home complex where we underslabbed the load side of the meter to the interior panel The poco TECO ran pvc latterals to our meter but required our side to have RMC above grade.Oh we griped but to no avail if we wanted a meter we had to have RMC but they could run pvc.How does that make any kind of sense.It is in their specs for what we have to install but they are exempt,the meter was in a driveway wall but covered by brick when done that really didn`t make a bit of sense.

No, it doens't make sense but you have to play by their rules. In my area, the only time they require ridgid for a pole riser is on a sidewalk or parking area. But, utilities in neigboring states require ridgid for all risers no matter where they are. They all have different rules.

By jes25: Are you saying the NEC would require SCH 80? I cant find that,

300.5(D) Protection from Damage. Direct-buried conductors and cables shall be protected from damage in accordance with (1) through (5).
(1) Emerging from Grade. Direct-buried conductors and enclosures emerging from grade shall be protected by enclosures or raceways extending from the minimum cover distance required by 300.5(A) below grade to a point at least 2.5 m (8 ft) above finished grade. In no case shall the protection be required to exceed 450 mm (18 in.) below finished grade.

Schedule 80 is the only UL listed Non-metallic raceway for protection of conductors
