EXHIBIT D-MINING PLAN
The applicant LEONE SAND and GRAVEL, LLC will prepaze a Storm Water
Management Plan (SWMP) and a Spill Prevention Control and Counter measure (SPCC)
plan, for this site. As you know each SPCC plan, while unique to the facility it covers,
must include certain elements. The elements required aze that the SPCC plan be carefully
thought out, prepared in accordance with good engineering practices, and should address
operating procedures that prevent oil spills; control measures installed to prevent a spill
from reaching navigatable waters; and counter measures to contain, cleanup, and
mitigate the effects of an oil spill that reaches navigable waters. To meet the above
requirements a Storm Water Management Plan and a Fuel Berm Management Plan, plus
a Spill Prevention Control and Counter Measure Plan will be done for this site. A pemut
from the Colorado dept. of Health & Environment Water Quality Control Division will
also be obtained. Copies of all of the above plans and permits will also be sent to the
Division of Reclamation, Mining and Safety.
LEONE SAND and GRAVEL, LLC will commit to placing topsoil and overburden
stockpiles along the entire low edge of all the mining phases as a first step of the mining
operations, the berms and pits created will control erosion and sedimentation. The
operator is committed to control (prevent) erosion and sedimentation from reaching any
drainage. All methods of control will be used, sediment traps, riprap, straw bales, earthen
berms and liners.
Bulk storage of fuel, and small amounts of lubricants, will be stored on site in an earthen
berm with an approved liner azound and below the storage containers. The earthen
structure will have a capacity of at least 110% of the tanks and containers tanks. This
type of structure will be leak proof and readily cleanable if a spill does happen. The liner
will form a pool that the liquid cannot escape to the surrounding areas. The other features
of this structure is that it will be designed in such a way that it will be easy to clean up
any possible spills. All spills will be soaked up with an absorbent material such as sand or
other substances that can absorb the spilled oils or lubricants. After the mixture of
absorbents and oil are cleaned up all the waste materials will be transported to the nearest
approved disposal site.
LEONE SAN and GRAVEL, LLC does agree and will commit to Division of
Reclamation, Mining and Safety permit condition as stated on page (b) six in the
