Executive Summary |
Risk Management Program for Newmont Mining Corporation
Carlin South Area Operations
Newmont Mining Corporation takes very seriously its responsibility in operating at the highest degree of chemical safety. A number of accidental release and emergency response policies are implemented and recognized as daily practices to insure our commitment to safety and implementation of safe procedures. As such, Newmont Mining's Carlin South Area Operations has adopted the following Loss Control Policy Statement:
"It is the policy of Newmont Mining Corporation that we will produce gold in an efficient manner, in harmony with the environment, while protecting the safety and health of our employees.
Newmont Mining Corporation will comply with all government regulations. Newmont recognizes government regulations as minimum standards and in many situations will establish internal standards, which will exceed the government requirements.
Newmont believes that the safety and he
alth functions can be managed proactively and will develop, implement and maintain safe working policies, procedures, practices, rules, guidelines, standards, etc. and develop a management system that is concerned with the safety and health of each and every individual.
All of us working at Newmont must strive to make the Carlin Operations a safer and better place to work. Newmont will hold each employee responsible, within the bounds of his/her control, for the maintenance of safe and healthy working conditions; for compliance with safety, health, environmental regulations and company procedures, and to do their job in a safe and efficient manner."
With this commitment Newmont recognizes that our safety procedures are also meant to assure the surrounding community the same degree of safety assurances.
In Addition to Loss Control's Policy Statement, The Mission Statement of the Environmental Department is as follows:
"Mission Statement for Environmental Compliance

Newmont as a major producer of gold within the Gold Mining Industry is taking steps to limit the amount of 112-R regulated substances used in the extraction processes. However, as a leader in innovative technologies, the use of two substances above EPA threshold reporting quantities has proven to be invaluable for gold extraction. Each of these substances is used in minimum quantities to produce maximum economic results, and both substances are located in remote areas that do not have potential impact to public receptors.
To verify the possible impact, or lack thereof, Newmont Carlin Operations enlisted the services of JBR Environmental Consultants Inc. to verify Newmont Carlin Operations Environmental Department's conclusions that the public receptors would not be compromised in a "worst case release".
The two substances found to be above storage thresholds for
EPA 112r reporting purposes are chlorine and ammonia (concentration greater than 20%). Each of these is discussed here.
Chlorine is used as an integral part in one of the South Area Operation's mills for the purpose of mercury extraction and recovery. The EPA's reporting quantity for chlorine is 2,500 pounds. At present Newmont stores 3,000 pounds in 150-pound cylinders at one of its warehouses. The "worst case release" scenario as shown by EPA's RMP air dispersion model, and confirmed by JBR Environmental Consultants, Inc., would be a radius of eight tenths of a mile. Newmont owns or controls property for a 2.7 mile radius miles from the source location to the nearest "public receptor" (one house), and is therefore confident that any accidental release would be inconsequential to the public.
Ammonia in the form ammonium hydroxide is used as an integral part of one Newmont's South Area Operations gold leaching processes through a patented extraction process. The EPA's reporting quan
tity for ammonia is 20,000 pounds. At present Newmont stores up to 30,000 gallons of ammonium hydroxide at one leach process area. The "worst case release" scenario as shown by EPA's RMP air dispersion model, and confirmed by JBR Environmental Consultants, Inc., would be a radius of 2.0 miles. Again, Newmont owns or controls the land for a 2.8 mile radius from the source location to the nearest "public receptor" (one house), and is therefore confident that any accidental release would be inconsequential to the public.
As a part of the ongoing safety training conducted by Newmont's Loss Control Department, all employees in the afore-mentioned areas are periodically trained in evacuation procedures should a release of these substances occur. In conjunction with any evacuation that might be necessitated due to a release or spill, 24 hour on-call phone lines have been established with not only the Loss Control Department, but also the Environmental Department and the Security Departmen
t. In a case of substantial release, area supervisors have been instructed, at a minimum, that the Loss Control Department and Environmental Department should be contacted immediately. Loss Control will make the decision as to whether the Security Department and Local Emergency Planning Committee should be contacted. The Environmental Department would be responsible for alerting either the appropriate EPA or NDEP agencies if this should be necessary.
Newmont Mining Corporation prides itself on the high degree of safety and environmental training classes that all employees have been exposed to. As a result, in the last 5 years there have been no accidents resulting in either injury or death to any onsite or offsite individuals from any of the listed 112-R substances that Newmont has used over that period of time.
The Newmont Carlin Operations Emergency Response Plan addresses fire, chemical, medical, and earthquake emergencies, as well as upset conditions. It discusses evacuation of
specific areas and a general evacuation of the plant site. Newmont has signed a mutual aid agreement with the Local Emergency Planning Committee (LEPC) and participates in annual drills set up by the LEPC. Our emergency response teams train on a monthly basis and are proficient in handling chemical spills, fires, confined space and high angle rescues on the property. In addition, they have been called on a number of occasions to respond to off-site chemical and petroleum spills. There are 23 Hazardous Material technicians among emergency response members who are trained to the 40-hour level and who receive a minimum of 8 hours of training on a yearly basis. While other identities in the Elko area have Hazardous Material trained individuals, at present Newmont has the only Hazardous Material Teams in the county.
In addition, as a part of the "Emergency Response Team Charter" at Newmont South Area Operations:
The Emergency Response Team will consist of a minimum of eight people on each
shift in the South Areas Operations. The team will consist of 12 hour shift employees as listed below:
South Area--8 minimum
2-Emergency Medical Technicians (EMTs)
2-People trained in mine rescue
* A minimum of 3 people will come from the Process Departments. (Milling and Leach)
Fire training will be conducted every Monday on the employee's regular scheduled shift and will last for a full 12 hours. Each person will attend one session per month. Fire Training will take place for the first 2 months of the quarter and sometime during the third month a drill will be held for each crew.
Members who fail to attend 2 training sessions per year will be removed from the team. Members may be excused from their regular training session if they will call their Captain and attend another scheduled session.
EMTs will attend an 8-hour training session to be held in Elko on the employees scheduled day off. Employees will be paid a regular rate of pay for the training. Each
EMT must attend 4 sessions in a 2-year period to meet their rectification requirements. The 8-hour sessions will be repeated once per week throughout the month.
Team members who are trained in Mine Rescue Techniques will handle:
All Confined Space Rescues
Hazardous Material Spills that can't be rapidly contained and neutralized.
All High Angle Rescues and Vehicle Extrications.
Mine Rescue Training will be held on the First and Third Thursday of each month scheduled on a regular scheduled workday. Each Emergency Response Team member who will respond in a rescue situation must attend one training session per month.
Emergency Response Team members engaged in rescue activities must attend a minimum of 10 rescue training sessions per year.
Newmont also maintains identical such teams at its North Area Operations that could be called on for assistance should an occasion require the additional support.
Newmont not only makes a constant effort to provide trained individuals in ca
se of an emergency, but also to illuminate possible emergencies to begin with. In this regard, and as an outcome of investigations performed while complying with 112-R, Newmont is re-evaluating our stock on hand of Chlorine. Mill Operations has been asked to look at the necessity of having 3,000 pounds of chlorine on hand at the warehouse at any one time. It is hoped that more frequent deliveries of lesser amounts will minimize risk at the facility.
Finally, Newmont South Area Operations requires that all new inventory items have any associated MSDS reviewed by both the Loss Control and Environmental Departments prior to any product and subsequent amounts being shipped on site. In addition to this, our Purchasing Department is presently being made aware 112-R substance threshold process limits to further minimize chemical risks.
Newmont South Area Operations looks forward to maintaining excellence in its Risk Management Program through all available resources.
