5.0 SPILL PREVENTION AND SPILL RESPONSE PROCEDURES
This section summarizes the routine operating procedures that must be followed to prevent releases
of substances subject to control under this ERP/SPCC. This Section also provides procedures to
follow in the event of a specific type of chemical spill and procedures to monitor the potential migration
of spilled materials. These procedures are the subject of training sessions for CC&V Team Members,
and they apply to any activities conducted by CC&V on the mine site.
' 5.1 General Spill Prevention Procedures
The following procedures primarily relate to on-site movement and use of chemicals. Team Members
' involved in chemical handling (including oils) will receive instruction on safe handling of storage
containers and materials handling during product transfers:
• Storage Containers: (1) Driving vehicles (trucks and forklifts) carefully and in accordance
with conditions to avoid collisions or ruptures of storage containers; and (2) constructing
adequate berms and barriers to protect storage containers.
' • Storage Containers: Making certain that there is adequate clearance when positioning a
truck or equipment adjacent to storage areas or distribution points and ensuring that the
operator has examined the surroundings to identify where a spitl would go and how they
' would control it.
• Storage Containers: Checking to make sure containers are securely placed to prevent
' tipping and spilling and in a manner that prevents collisions with mobile equipment.
• Transfer of Materials: Examining fittings and transfer lines or hoses to be assured of tight-fits
that will not come apart during transfer,
' Transfer of Materials: Examining fittings to assure they are in proper working order and do not
leak or lose fluid during transfer.
• Transfer of Materials; Ensuring that valves are closed and transfer pipes are drained or
contained prior to disconnect.
• Transfer of Materials: Examining the "weak spots" of any transfer procedure and visualizing
where the substances would go and what control measures would be used should a transfer
line break or leak. Taking a second look at these "weak points" to see if anything can be
done to further prevent a release. "Cleaning up" spills.
Copies of the ERP/SPCC Plan are located in key areas. Refer to section 7.1 for a complete
' distribution list. The content of the ERP/SPCC will be included in training sessions.
Inspection of storage facilities is completed routinely (Appendix G). The NaCN, NaOH, and HCI
storage facilities are checked during routine operations by Process Department personnel to identify
and repair leaks and to maintain containment. Petroleum-based materials in the maintenance area
are checked routinely to identify and repair leaks and maintain containment. The inspection includes
checking for visible signs of leakage, checking containers and piping for any sign of weakness, tearing
' or rupturing, and checking for cracks or breaks in containment berms, as well as for any significant
reduction in the capacity of the containment. Any observed problem would be immediately reported to
a supervisor and repaired. Spillage wilt be cleaned up as appropriate for the substance involved.
Inspections are recorded and the records retained.
' Labels on storage containers are also part of the chemical spill prevention program and are posted at
material storage areas. These labels identify the contents of the permanent storage vessels and
' applicable sections of the fire code. These (abets are posted to remind team members of the nature
of the material, to promote safe practices, and to provide clear direction about the spill prevention and
control procedures to be employed.
