INERT FILL NOTICE (RULE 3.1.5(9))
Firestone Gravel Resource M-1996-052
From time to time over the life of the mine we may import inert materials as defined in
Rule 1.1(20), into this mining operation. It will be recycled and sold or used to partially
construct the slopes that will be left when mining ends. Some may also be used io backfill
portions of the mined area. If courser fill is used it will then be covered with finer material and
revegetated where required by the permit. If the material is good dirt we will use it to
supplement the topsoil needs for the mined area. Sloping will not be delayed if fill is not
available since the fill will supplement material on the site at this time.
The exact amount of material to be imported is unknown. We will record the volume
imported each year and keep a running total. If needed, the total can be supplied to the Division
so that the Division will know how much material was imported and how it was disposed of.
Importing fill will begin when operations at this mine resume. We will continue to
import inert fill until reclamation is complete or we no longer have a source.
No specific compaction rates are proposed for the fill. The material usually available
contains smaller pieces of concrete, or dirt mixed with the larger pieces of the same material.
This makes it very difficult to achieve a specific compaction rate. While we take no action to
reach a specific compaction rate, the way the material is placed tends to compact it. We run
heavy equipment over the newly placed inert fill and the material is compacted in that area as a
result. Stabilization of this fill material is not a concern because of the limited amount used in
the slopes and the way it is placed. What voids do remain are usually under large pieces of
material and little settling is possible. No structures will be built on the fill, nor will the depth of
the fill be so great as to affect offsite lands if settling occurred.
