RE: H-G Loadout A plication (C-92-081) Review
I have reviewed Peabody Coal Company's (PCC) application for the H-
G Loadout (C-92-081). Sections I reviewed include:
Soil Resources: Vol. I Tab 9 plus Exhibit 9-1
Vegetation: Vol. I Tab 10
Topsoil Handling Plan: Vol. II Tab 19
Revegetation Plan: Vol. II Tab 20
Soil Resources:
There are three existing topsoil stockpiles on the site.
Survey by the applicant estimates about 55,100 cu.yd. of
suitable topsoil material. The lower depths of the
stockpiles exhibit high carbonates and saline and sodic
conditions. The soil types in the surrounding
undisturbed sites exhibit elevated EC and SAR's as well.
the soil textures found in these stockpiles are silty
clays to silty clay loams. PCC has chosen plant species
adapted to salt affected soils in their seed mix.
PCC is not proposing at this time to create any new
disturbance than that which already exists on the site.
In the event that PCC may propose any increase in
disturbance, PCC proposes to salvage topsoil only to
depths that SAR and EC in the subsoil are not
restrictive. For the Morapos soil salvage depth would be
to 9" depth. In the un-named soil mapping unit 5AI
salvage depth would be to 24". PCC is requesting a
variance from salvage of the Spicerton variant mapping
unit due to high SAR of 13 below 1" depth and high EC
below 8" depth. This soil type also exhibits high
carbonates and bicarbonates.
