6.4.4 EXHIBIT D
This exhibit substantially changed with this submission due to the Division's adequacy items,
community input and project modifications. The new exhibit is provided to replace the previously
submitted exhibit.
6. The mine plan includes topsoil stockpile management and preservation with vegetation.
The narrative now reads as follows:
Topsoil stockpile erosion caused by wind will be minimized by strategically locating
the stockpiles on the east side of the mesas whenever possible, blocking effects of the
prevailing westerly winds. Topsoil that is not replaced on backfilled slopes in a time short
enough to avoid deterioration will be seeded with the seed mix presented in Exhibit E,per
the recommendation of Mr. Richard Rhoades on April 29,2016. Topsoil stockpiles will be
seeded during late fall.
7. Fremont commits to salvaging as much topsoil/growth medium as possible with a minimum
objective of six inches.
8. Because the Badger Hills area is a fragile semi-arid eco-system,effort will be made to
maintain historic stormwater flow onto native,undisturbed areas. The narrative now
reads:
Because Badger Hills is a semi-arid environment, stormwater best management
practices (BMPs) will filter and release storm water that falls on to or flows across the
affected area as much as possible. Berms and swales will be constructed that direct storm
water to detention basins or filtration outlets. Detention basins will be constructed in areas
where storm water will infiltrate within 72 hours. Straw bale or straw wattle filtration
outlets will be constructed along and in swales and berms filtering sediment, releasing
storm water onto undisturbed areas at historic flow rates wherever possible. Stormwater
BMPs (berms, swales and detention basins) will be constructed of overburden and/or
mining fines.
9. The narrative now reads:
The target reserve is the Cascajo gravel terrace that ranges in thickness from 10 to
15 feet. Gravel will be mined 10 to 15 feet deep to shale or clay loam the stratum
immediately below the target reserve.Topsoil and overburden is minimal with prominent
gravel outcrops.
10. The first paragraph of the exhibit includes the following sentence.
Gravel will be mined 10 to 15 feet deep to shale or clay loam,the anticipated
stratum immediately beneath the material to be mined.
