9.
SPS 385.30(2)(a)(a) Redoximorphic features or mottles shall be interpreted as zones of seasonal or periodic soil saturation or groundwater, except as provided under
sub. (3).
SPS 385.30(2)(b)
(b) Unless otherwise determined under

SPS 385.30(2)(b)2.
2. The lower boundary of overlying fill material where no buried A horizon exists.
SPS 385.30(3)(a)(a) Without filing a report under
s. SPS 385.60 (2), a certified soil tester may discount the following conditions, not limited by enumeration, as indicators of seasonally saturated soil:
SPS 385.30(3)(a)1.
1. Fossilized soil color patterns formed by historic periodic soil saturation.
SPS 385.30(3)(a)2.
2.

SPS 385.30(3)(a)3.
3. A soil profile where redoximorphic features are confined within 24 inches of tension saturated silt loam or finer textured soil immediately overlying unsaturated coarse loamy sand or coarser textured soil that has a depth in the coarser material adequate to accommodate a distribution cell and dispersal zone.

The governmental unit or department may decline to provide such assistance, and defer to the use of soil saturation determinations pursuant to
s. SPS 385.60 or some other method.
