ResponseSpill and CountermeasuresNEWMONT •r the Cresson Project NORTH AA11FRICA Sustainability& External Relations At the Midway Fuel Farm,the underground lined area is not suitable to serve as secondary containment during the portion of the year when this ground is frozen and/or snow and ice-covered.This renders the subsurface soil impermeable and unable to function as secondary containment.Should a significant or catastrophic release occur from one of the single-walled fuel storage tanks the release would flow overland to the north and follow the road towards the Ironclad Facility and NTS. 1.3 External Reporting—Reportable Quantities Releases that occur out of doors and outside an engineered containment area and which meet or exceed the numeric thresholds known as"RQs"as listed in Table 1, require reporting to appropriate county,State and/or Federal agencies.Spills or releases of these substances should be immediately reported to S&ER and CC&V Team supervisors. Use Cintellate provided on the CC&V prospector page to document the spill or release. Provide the Cintellate Report to S&ER as soon as possible within the same shift of the occurrence so that external reporting can be accomplished within the required 24 hours.

Use Table 1 to calculate the amount of cyanide released from known quantities and concentrations. (4)CC&V internal reporting requirements Spills to land that exceed the RQ volume criterion in any 24-hour period must be reported to external agencies in accordance with this SRP(see Section 5.0 for more details).A S&ER representative will complete external notification, if and when necessary.Table 1 lists RQs of chemicals that require external spill reporting.SDS's for specific products are contained in Appendix B. 1.4 Engineering and Structural Controls to Guard against Spills The Cresson Project has been constructed with spill containment around fuel storage areas,chemical storage areas, maintenance areas,and the areas in which cyanide solutions are present.Secondary containment structures have been designed to prevent spilled materials from entering stream channels, escaping onto areas subject to stormwater runoff, and migrating off site.Such control features will be maintained and will function at their design ----- - ----- ----- ----- -I - - - Department THIS DOCUMENT IS UNCONTROLLED IN HARDCOPY FORMAT Doc d:NA-CCV-SER-PLAN- 1930 4----------------------------------------------------F------------ -------------------------------------------------------------------------------------------F-----------------------_---------.....-.......,......._......;
