Map 1 of Appendix W depicts all previously planted parcels at the site. Each parcel identifies
the acres and the year seeding occurred.
Trapper permanently seeded zero acres of land in 2022. Acres seeded during 2022 are discussed in
section 1.2.4 of Appendix W. Revegetation seed mixes are discussed in section 7.3 and associated tables
of the report. Trapper included an invoice from Stevenson Intermountain Seed, Inc. in Section 7 of
Appendix W illustrating the reclamation seed mix utilized.
Section 1.2.5 of Appendix W discusses the cultural practices conducted in 2022. Separate sections in
the report discuss each unique practice. Cultural practices include and are not limited to:
o Drainage reconstruction
o Development drilling
o Topsoil pile construction
Rule 2.04.13 (2):
Section 3 of the report indicates that improvements and repairs were conducted on reconstructed
drainages. No new drainage construction occurred in 2022. Dredging of sediment pond No Name#2
occurred and dozer basins in East Pyeatt,Oak,Middle Flume and Deal systems were cleaned.
Table 5-1 in Section 5 of Trappers report provides geographic locations for each of the topsoil stockpiles
and the approximate volume stored in each pile. Topsoil stockpiles are depicted on the maps associated
with the submission in Appendix W. Over the course of 2022 four new topsoil piles were constructed,and
one topsoil pile nearly depleted as topsoil laydown in D Pit was staged.
Stock tanks and dozer basins are discussed in Section 6.0 of the report.
In accordance with section 3.6.3.5 of Trapper's permit, Trapper Mine must provide the Division with the
proposed list of plant species to be used each year. It appears,per Tables 7-Ithrough 7-4 of the ARR
submission, the number of species for plant type (grasses,forbs and, shrubs) and the amount of seeds to
be applied are in accordance with Trapper's approved seed mixtures.
No vegetation monitoring occurred in 2023.
Acres disturbed should not be greater than the sum of:
o Acreage in active mining
o Backfill and grading
o Long term facilities acres.
For the 2022 ARR Trapper's values provide the above result. However, DRMS calculates 6,906 acres of
disturbance versus Trapper's 6,900.7 acres.
