Site Preparation:

Soil preparation is a critical first step to re-vegetation. Given the location of this site and
feasibility of hauling in topsoil, it was decided upon to eliminate hauling topsoil to the
site or haul from the existing topsoil piles onsite and utilize the soil conditioners outlined
below. The soil conditioners provided below have been used by QB Energy Oper ating
on many disturbances across the bookcliffs at similar elevations/terrains and has been
very successful over the years. The existing top-soil piles were constructed during the
1980’s. The piles currently have very good, dense vegetation growth over the piles and
utilizing the topsoil would create more of a disturbance. Also, the inner portion of the
topsoil has now been buried for approximately 40 -45 years resulting in a deterioration of
organics which would not be suitable for placing over newly disturbed areas and
resulting in the use of soil conditioners, nevertheless.

The following steps should be completed prior to seeding. If the operator is reclaiming
an area where no contouring is required, a single ripper behind a dozer shall be utilized
for deep de-compaction promoting growth for the area. A disc will likely not alleviate
compaction enough in these areas to promote growth. By loosening these soils it will
promote root growth and firm enough for good seed to soil contact. It is ideal for the
surface to be relatively free of rocks, debris, and dirt clods greater than 3 inches in
diameter. If the operator is reclaiming an area that required re-contouring efforts, the
soil will already be loosened their for deep de-compaction will not be necessary. A rome
disc behind a tractor can be utilized to alleviate the surface an d prep for seeding efforts.
Given the existing conditions of some areas within the Colony Mine, there may be spots
that are difficult to achieve all that is stated above and are not required but within good
reason may be attempted.

There are several other types of implements that can be used to achieve this that can
be pulled behind tractors or dozers. These implements consist of disk, chisel plow,
subsoilers, and harrows. Depending on the contractor’s choice, these are acceptable
options to achieve soil preparation. These types of implements are typically used on
slopes less than 2:1. Areas of the Colony Mine can be steeper than a 2:1 and an
excavator can be used for soil preparation, which is also an acceptable choice.

Seeding:

There are many types of seeding techniques that can be used, but for the Colony Mine,
two main types of seeding will be used given the past success rate of each from
surrounding locations. One will be drill seeding and the other will be broadcast. The
intent is to take advantage of drill seeding, which has the highest amount of success,
where this can feasibly be completed. Slopes that or 2:1 or less will be drill seeded .
Contractor shall verify and calibrate the seeder to achieve the intended seed mix note d
above.

Where steeper slopes are encountered and prohibit the use of tractor or dozer,
hydroseeding or broadcast seeding shall be completed. The Colony Mine has large
areas of re-seeding which allows the use of handheld broadcast seeder. If any areas
are prohibiting the use of the broadcast seeder, hand broadcast seeding can be
completed. In either method, to achieve the highest amount of success, the recently
