If I wanted to run PVC under the hangar slab, is it really required to be concrete encased?

501.10(A)(1)(a) Exception states 2" concrete encased for the PVC, but then goes on and says the concrete encasement can be omitted if you comply with 514.8 Excep 2 AND 515.8(A).

In the Handbook there is a explanation section on this: "These provisions are for specific occupanceies where there has been considerable experience with underground nonmettallic conduit." What does that mean?:?

Thanks for any feedback.
