Berkeley Lewis (Environmental Restoration and Reclamation Co., LLC)
Reclamation within each active mining zone will occur when processing materials in that zone have been
completed for the season. Following the completion of the year’s active mining area, the disturbed area will be
immediately reclaimed before moving to a new 1.4 acre zone to be mined in the subsequent year. Reclamation
will include backfilling the mined area with the overburden generated by mining the excavation area, and graded
to match the topography of pre-mining conditions. Backfilled material will be compacted to 90% maximum
density. Stockpiled topsoil will be re-distributed evenly over the disturbed area, and compacted to 70%
maximum density. The area will be covered with jute netting and straw wattles, and then seeded and planted
with native species

All old equipment and scrap steel has been removed, with the exception of the water storage tank and the 40' Conex
container. At the end of our mining efforts, the small processing shed, the concrete slab and any remaining pieces of
small materials will be removed from the site. The old log cabin and the water well system will be left intact.
The processing shed is portable, and needs ot only be unbolted into its component parts. The water storage tank and 40'
container will be given to local haulers in exchange for their removal. The slab will be jack hammeres into small pieces
and buried as land fill in one of the ponds to be filled in. Small parts will also be guven to the haulers.

*NOTE This is the value of plant structures, buildings and equipment on a salvage basis -- e.g. after the
structures and equipment have been removed for sale or use off-site. In order to include net salvage
value in the financial assuranace calculation, the operator must provide a letter of agreement, signed
contract, bid, or quote from an independent company which provides industrial dismantling or equipment
salvage services, or is in the business of buying and selling scrap metals or similar products.

**Note This value must be obtained by manually adding items previously entered in sections
A, B, & C that are related to removal of items for which salvage value is being claimed.
This manual step is necessary in order to apply salvage value only towards costs of
removing equipment for which salvage is being claimed, not towards other demolition
costs.
