87. In the last paragraph on application page 2.05-3, it is stated that "topsoil will be salvaged
and stored in stockpiles". Will this also occur for subsoils (Section 2.05.4(2)(d))? Will
subsoils be segregated from topsoils? (DIH)

oS ~,3b topsoil piles. Please provide infotmation on the volumes of the topsoil stockpiles. This
'~, information is necessary for the Division to conduct cost estimate verification.
89. Permit application page 2.05-10 indicates that upon clearing of vegetation from the head-
of-hollow fill azeas, LCC proposes to burn the vegetation. However, text does not include
`,' any mention that topsoil will be removed prior to the contour mining cut. Please add this
~~,~ text. Rule 4.09.1(4) allows for utilization of the organic matter for mulch or to improve
b~ ~ the condition of the topsoil. The Division considers incorporation of the organic matter
into the salvaged topsoil beneficial to the soil fertility, provides a native amendment to

use overburden material as a plant growth material a demonstration adhering to rule

If excess soil exists iii other locations of the mine, along roads proposed to remain as
permanent, or location where available soil is in excess, RR loadout, these excess soils
may be proposed to be utilized at the surface mine area.
