2.05.4 Reclamation Plan
According to Richard Domingue's inspection report .dated
June 24, 1981, "Wyoming Fuels must provide a description
and defense of the method used to provide compaction of
the overburden replacement in the pit by July 31, 1981.
As discussed in our April 14, 1981 permit application,
backfill compaction will be accomplished by benching the
backfill in several lifts and wheel rolling.
Because the blasted overburden material has excellent size
distribution, compaction should be excellent. The individ-
ual benches will be 50 to 75 feet high as dictated by
mining requirements, and will be constantly changing.
Generally, overburden from near the pit bottom will be
backfilled in the lower lifts and overburden from upper
pit levels will be backfilled in the higher lifts. This
will be both cost-effective and helpful in reestablishing
relative premining strata placement.
2.05.2(2)(e)(vii) Attachment No. 3 of this Addendum is an
example of Wyoming Fuel Company's soil
testing program.
2.05.4(2)(d) A series of backhoe pits will be dug in the area
of proposed topsoil removal. Operators will be
instructed as to color changes and depths in the
soil profiles to be removed. Vegetation will
also be used as an indicator for topsoil removal.
Proposed topsoil stockpiles are shown on Figure 2
of tl~e April 14, 1981 application. All topsoil
piles will be seeded with a mix presented in Table
VI of that application.
