Releases to Ground Water
CC&V operates a VLF monitoring system and ground water monitoring wells to determine if
i
releases are occurring from its leaching operations such that ground water quality may be
impacted. Releases to ground water, should they occur, are generally not rapid or instantaneous,
thus providing appropriate time for evaluation and remediation. CC&V is committed to a
DRMS regulatory required response to an increase in certain water monitoring parameters that is
contained in Amendment No: 8, Volume I, Project Description page 98 and also in Appendix VII
of this document.
Spill Path Monitoring
If a spill or leak has the potential to migrate from the point of occurrence, spill monitoring will
be implemented following clean up. Development of the monitoring plan will be determined by';
the nature and extent of the spill and the potential environmental effects created by the spill. Ally
monitoring and sampling will be completed under the direction of the Environmental Resources ~
Department.
The potential for spills to migrate from the point of occurrence is minimal. These materials will
be quickly absorbed into soil material. If a spill of these materials has the potential to migrate to
surface water, a berms) will be placed upgradient of the potential point of entry to the water and
surface water monitoring will be implemented downstream, if necessary. All monitoring and
sampling will be completed under the direction of the Environmental Resources Department.
• Spill monitoring equipment is available on site. Soil along the spill pathway will be monitored
and decontaminated and/or moved as necessary. If there is a potential for the spill to migrate off,-
site, samples will be obtained expeditiously from down-gradient, existing surface and ground
water. stations and any. additional water monitoring points deemed appropriate to monitor the
potential migration pathways. The spilled material also may be tested to evaluate the
effectiveness of mitigation.
VIII. Review, Evaluation, and Revision of Response Procedures
All exposure and release incidents and accidents shall be evaluated to identify their cause and
determine the measures to be implemented designed to prevent their reoccurrence. Such
measures may include equipment changes, revised standard operating procedures, or new or
enhanced worker training. ~,
CC&V shall review and evaluate the CERP annually and after any incident requiring its
implementation. Based on these reviews, the CERP shall be revised as necessary to ensure that it
remains current and effective. The date of the most recent review shall be noted on the CERP's
title page.
CC&V shall- conduct mock emergency drills annually to test its response procedures and
capabilities. Some of these drills may be specific to cyanide releases while others may simulate i
