We believe that all employees, our host communities, government, and all other stakeholders have a right to expect a high standard of environmental performance from Teranga. Since our mining operations may have both temporary and long-lasting effects on the environment, we take a precautionary approach throughout the life of mine. We first assess any potential environmental impact and then evaluate how to avoid or mitigate it, with the aim of preserving the long-term health, function and viability of the natural environments affected by our operations.
Committed to the highest standards of environmental management, we conduct our activities in compliance with the laws and regulations of Senegal. A legal register has been compiled and is updated regularly to ensure that we are kept abreast of regulatory changes and that our standards are in compliance with the best practices available. An inspection program monitors the environmental performance of each of our departments at site and performance indicators are disseminated on a weekly basis to department managers. Incidents or failures to respect the environmental management standards are addressed through corrective actions.
Teranga's activities are energy dependent. We rely on a 36 megawatt power plant located on site and our main energy sources are heavy fuel oil and light fuel oil sourced from Dakar. While our energy consumption has increased commensurate with growth in our operations, Teranga continues to pursue energy efficiency initiatives that reduce greenhouse gas emissions.
Teranga recognizes the impact that its activities can have on climate change and the risks associated with this issue and we have taken actions to reduce our greenhouse gas emissions, including the implementation of a video-conference system to reduce flight travel and the installation of an incinerator to burn waste and limit emissions through fume confinement. Additionally, we have a preventative maintenance policy for our mining equipment fleet to ensure optimal efficiency.
As water is critical to our operating activities and to the communities surrounding our mine site, we take strides to reduce water use and to minimize our impact on the availability of this resource. A monthly monitoring program is in place as part of the environmental management system to ensure the quality of surface and ground water. Drinkable water is maintained in compliance with the World Health Organization standards.
In order to minimize our environmental impact, we are focused on limiting the use of raw materials, hazardous materials and critical consumables, such as explosives and tires for our mining equipment. Teranga fully complies with chemical and hazardous products legislations and has established procedures to ensure that chemicals are handled appropriately. Each hazardous or chemical product is registered and pre-approved before being accepted on site. Enhancements made to our fleet management in 2014, increased the life of tires for our mining fleet by 10% over the prior year and reduced the number of tires used per ton of ore mined by 24%.
All of our projects have a specific mitigation plan for land use and rehabilitation. These plans are included in our Environmental and Social Management and Monitoring Plan and agreed to by stakeholders. Rehabilitation plans are operational documents regularly reviewed and updated to ensure they are kept current with mining operation developments.
Our site is located in the Faleme hunting area approximately 40 kilometres away from the Niokolo Koba National Park. We recognize that our activities have an impact on biodiversity and on ecosystems services and that our activities cannot be dissociated from these ecosystems. Therefore, all of our projects have a specific management plan for biodiversity protection and promotion. Biodiversity is fully integrated into our Environmental Management System and is part of all Environment & Social Impact Assessments that we undertake.
Waste is a by-product of our activities and therefore waste management improvement is one of our top priorities. We continue to work with our employees and business partners and, in 2014, implemented better waste management controls and partnered with several suppliers to dispose of waste off site.
Air quality is assessed through Teranga’s environmental monitoring program. A key air quality issue is related to dust generated by traffic from our supply chain and blasts. In 2014, Teranga worked with one of its suppliers to test a dust reduction program that involved spraying molasses on the roads. Additional testing is required before implementation in nearby affected villages.
