ResponseSpill and CountermeasuresNEWMONT .r the Cresson Project • Sustainability& External Relations capacity.To ensure that synthetically lined earthen containment berms are working properly,they will be inspected monthly,they will be cleaned out when foreign objects or trapped water threatens to diminish the containment capacity, and they will be repaired whenever cracks in the berm or tears in the liner compromise containment. Concrete containment structures will also be inspected, cleaned out,and repaired as required. The mining areas,vehicle maintenance facilities, and leaching/processing facilities all have built-in protections against spills and leaks. Specific design criteria,which emphasize attention to spill and leak prevention, containment,chemical storage,and environmental monitoring, have been incorporated into the overall plan. Examples of specific facility designs that help control spills include: (1) high level alarms and continuous recording of tank volumes in the Ironclad and New Truck Shop bulk oil storage facilities; (2)designed and constructed floor sumps in the Ironclad small vehicle shop and truck shop; (3)engineered oil skimmers and a water filtration system in the large truck wash bay;and (4)aerosol can depressurizing units mounted on used paint storage drums within over-pack drums at various locations throughout the site. Certain facilities at the Cresson Project have been located to provide for optimum environmental control.Such facilities are located outside of drainages and flood plains or,surface water diversions have been installed to minimize surface water run-on and run-off. Transfers of materials subject to control under this Plan will be conducted in accordance with CC&V procedures described in Section 4.1.12. CC&V Team Members assigned to operations involving transfer of chemicals or fuels and lubricants are responsible for implementing these procedures. 1.5 Management Controls to Guard against Spills The Cresson Project recognizes certain Best Management Practices(BMPs),which can prevent many spills from occurring.Among the more important BMPs employed at the Cresson Project are the following: • Good Housekeeping-This refers to the conscientious effort of employees to maintain work areas so that spilled materials are not allowed to be released into the environment. Clean, uncluttered work areas promote safety and help prevent spills. • Preventive Maintenance-CC&V personnel utilize the inspection and monitoring function as a means to identify where and when BMPs need to be updated. CC&V management is committed to updating and improving BMPs through periodic inspections(see below)and follow-up. • Material Handling Practices-Environmentally safe handling of materials which could be spilled is an important practice at the Cresson Project. Hazardous materials are stored inside curbed containments in the ADR plant, bulk oil is stored within concrete-walled or lined earthen berm containments described elsewhere in this plan, and employees are instructed in the environmentally safe handling of these products.These are some of the examples of materials storage practices utilized by CC&V team members to reduce the likelihood of material spills. • Visual Inspections-Visual inspections are conducted periodically and records are maintained onsite. r---------------------- ------------------------ ---------------------------------------------------------------------------------------------------------- - - PLAN - Department THIS DOCUMENT IS UNCONTROLLED IN HARDCOPY FORMAT Doc Id:NA-CCV-SER- 1930 f--------------------------------------------------------------------------------------------------------I---------------------------------------------'------4-------------_---..----.----------------------------1
