• o Crushing Plant: This small 35' trailer consists of the crushing equipment. It is possible
that stormwater can fall on this, therefore silt fencing will be installed downgradient of
this equipment. Also, operators will be instructed on how to avoid spills of ore/waste
rock. They will be instructed to continually monitor this and scoop up spills that may
happen around the conveyor belts and return the rock to the process stream.
o Pipelines: There are process water/tailings pipelines located above grade at the site. The
tailings disposal line is a 2" HDPE double-walled pipe to provide for secondary
containment. The recycle water line is 1.25" HDPE double-walled pipe to provide for
secondary containment. A tailings process water analysis in provided in the appendix.
This pipeline shall be inspected on a monthly basis by walking the line to look for leaks.
Leaks shall be repaired immediately. If a leak occurs, the contamination does not
warrant high alarm. The leak shall be allowed to evaporate and any solid tailings
component shall be scooped up and disposed of in the lined Tailings Impoundment.
o Chemical Storage:
• Diesel fuel - A 500 gallon double-walled tank will be located at the vicinity of
the Mobile Mill Area. This will provide assurance that any potential tank leaks
will be contained in the secondary vessel. Personnel will be trained to use care
when re-fueling to avoid drips. Fill nozzle will not have a latching mechanism
so that an operator must be present when fueling. If a spill occurs, operators
will be instructed on the approved methods of clean-up.
Contact management immediately
• Identify the source of the spill
• Contain the spill and eliminate the source of additional spillage
• Use absorbents (OilDry, pads, etc.) to soak up spilled material
• Dispose of absorbent materials in approved manner
• • Collect any contaminated soil for proper disposal.
• Lubricating oils, hydraulic oils, etc. - Several 55 gal. steel drums of these sorts
of lubricants may be stored outside. They shall be stored on wooden pallets to
keep bottoms from rusting. All openings will have hand pumps, valves or plugs
installed to keep them closed from the environment. No open buckets will
allowed that may catch moisture. Good housekeeping practices will be taught to
operators to keep the area clean. If a spill occurs, operators will be instructed on
the approved methods of clean-up.
• Contact management immediately
• Identify the source of the spill
• Contain the spill and eliminate the source of additional spillage
• Use absorbents (Oi1Dry, pads, etc.) to soak up spilled material
• Dispose of absorbent materials in approved manner
• Collect any contaminated soil for proper disposal.
¦ Hydrated lime/soda ash - Bags of this material will be stored outside on top of
wooden pallets. The stack will be covered by a heavy plastic tarpaulin to keep
rain and snow off. These chemicals are fairly benign and special handling is not
required. Operators will be instructed to continually police this area for spills
and practice good housekeeping.
o Final Concentrate Product: The gravity and flotation concentrate products that are
collected are stored in Intermediate Bulk Shipping Containers which are palletized
polyethylene containers surrounded by a steel skeleton framework for protection from
impact and crushing. These containers measure approximately 42" cubic. At any time
there may be upto 30 of these such containers stored on site, staged prior to
transportation off-site. These containers provide excellent isolation from stormwater. In
the event one becomes damaged and spilled, operators are instructed to scoop it up and
return to a container that is not damaged.
