yes
Expert:  Mike replied 7 years ago.
EPVC Conduit should be buried 18" but there are a few exceptions, a couple of them being:

1)If you cover it with 2" thick concrete, it would only have to be 12" deep
2)If the circuit in the pipe is 120V or less and it's GFCI protected and protected by no larger than a 20A breaker, then it also would only have to be 12" deep
