Table 4.1, Description of Potential Pollutant Sources
PS # Potential
Pollutant Location Purpose Outfall
Likelihood
of Contact
with Storm
Water
Basis
11 Oils and lubricants. Bulk Oil Storage
northwest of #1 Shaft
Bulk oil storage OF-3
(W. Fork Clear Creek)
Unlikely Storage is within a building and spills during loading and loading would be quickly realized and
cleaned up. Building has a bermed containment capacity that exceeds the volume of the largest
single container in the storage area.
12 Used lubricating oil. Used Oil Storage Tank
northwest of #1 Shaft
Used oil storage and transfer. OF-3
(W. Fork Clear Creek)
Unlikely Tank is inside concrete containment. Spills during truck loading are unlikely and would be quickly
realized and cleaned up.
13 Gasoline and diesel
fuel.
Lower Yard Fuel
Island
Fuel Island-Lower Yard OF-3
(W. Fork Clear Creek)
Probable Spills are quickly realized and cleaned up. Tanks are within containment. Unloading and fueling
equipment is covered.
14 Oils and/or antifreeze. Staging Area South of
#2 Shaft
Storage of equipment and
containers in the area south of #2
Sh
0F-8a
(Butler Gulch)
Likely Containers are outside.
15 Oil, diesel fuel,
lubricants and
miscellaneous.
contaminates.
5-Shaft Salvage &
Equipment Yard
Staging area for lumber,
construction equipment and
materials, pipe, good steel, new
fill material, unattended vehicles
scheduled for salvage, sale, long
term storage, or repair.
OF-4, OF-5
(W. Fork Clear Creek)
Likely Unattended vehicles scheduled for salvage, sale, long term storage, or repair could have the
potential for oil and fuel leaks that could report to storm water.
16 Oils, greases, fuel, and
explosives.
Emrick and Hill
Contractor Yard
Storage of explosives and mixing
of ANFO.
OF-6
(W. Fork Clear Creek)
Probable Presence of outdoor diesel tank and loading and unloading of products.
17 Fuel, oil and
lubricants.
Underground fuel
transfer station/#5
Shaft Fans and Motors
Unloading and storage of fuel for
use underground.
OF-5
(W. Fork Clear Creek)
Probable Unloading/fueling occurs in a depressed area designed to capture a release should one occur during
transfers and tank is within containment. The #5 Shaft fans/motors could have the potential for oil
or lubricant leaks that could report to storm water. Spills are quickly realized and cleaned up.
Fans and motors are inspected, maintained and repaired, as necessary.
18 Oils, lubricants and
anti-freeze (new
products).
Mine Surface
Warehouse
Storage of new products including
oils, lubricants, and anti-freeze.
OF-7, OF-8a, OF-14 Unlikely Storage is within a building and spills during loading and loading would be quickly realized and
cleaned up. Building has a bermed containment capacity that exceeds the volume of the largest
single container in the storage area.
M-3 Flows from process
area and runoff from
Coherex Station
Coherex Station Coherex Storage OF-M1
(Williams Fork)
Unlikely Marginal separation from Coherex Station to either process area or adjacent storm water area
increases potential for storm water from process area or runoff from Coherex Station to flow
outside the process area during storm events. An existing shallow swale currently provides
separation.
M-4 Oils, greases, and
other pollutants from
stored equipment.
Storage Area across
from Pond
Maintenance Building
Storage of electrical equipment
and other material.
OF-M1
(Williams Fork)
Likely Some of storm water runoff from storage area drains away from process area. Oils, greases and
other pollutants from stored equipment could report to storm water.
