(OP)
Is there a requirement to place bedding of a certain minimum thickness below a buried pipe? I am trying to find a source that says that if the soils under the pipe have sufficient capacity, then there is no minimum requirement for bedding materials.

Bedding may be just rearranging the existing soil a little or importing new material. As CVG stated, it depends on what, where and the guy that writes the check.

The purpose of specifying bedding is well described here by several commenters. The reason bedding is normally specified, even when native soils may appear satisfactory is quality control. Uniform bedding support is critical to long buried piping system life and reuse of native soils, removed, possibly screened, reapplied and satisfactorily compacted is a common practice. However, just laying piping in an excavated trench is asking for future problems and is not allowed in many piping standards.
