Activities such as mining, milling and transportation at our Red Dog Operations, located in the territory of the Iñupiat people of Northwest Alaska, generate dust, which has the potential to affect the environment.

The Iñupiat have long engaged in subsistence hunting, fishing and gathering on their lands. A Subsistence Advisory Committee, made up of residents from the communities of Noatak and Kivalina meets regularly with NANA and Teck representatives to review all subsistence-related issues and to guide subsistence protection activities at the mine and associated facilities, including the management of fugitive dust.

We recognize that dust mitigation is important in order to ensure the Iñupiat people’s way of life is protected and, as such, we take measures to protect air quality through our fugitive dust mitigation program.

Since mine operations commenced in 1989, Red Dog has invested more than $24 million in an aggressive program to reduce fugitive dust emissions through operational and facility improvements and activities including:

• Designing engineering controls to either prevent dust from occurring or to keep it contained
• Installing air quality control devices, such as baghouse dust collectors, in storage and transport buildings to more efficiently remove dust from the air
• Enclosing buildings and conveyors at Red Dog’s port and mine to keep the amount of dust on-site to a minimum
• Applying a mixture of non-toxic calcium chloride and water to the 52-mile road between our mine and the port to control dust generation
• 将卡车车队更换为硬覆盖的拖车以运输集中权

由于这些措施，2007年进行的风险评估得出结论认为，在没有限制的情况下，可以在所有地区消耗生存的食物是安全的。两种社区的粉尘监测研究最靠近雷诺州（35英里）和Kivalina（50英里外）Žalso得出结论，环境中存在的灰尘水平不会对人类带来任何健康问题。我们认识到需要不断监测和测试水质，空气排放，鱼类，当地驯鹿种群，植物和浆果以及其他潜在的食物来源，以确保生命性食物是安全的。这些评估和研究是与纳纳的合作制定和实施，并与社区分享。

We continue to monitor and evaluate our performance and look for opportunities for further improvement. For example, trials for potentially more effective road dust suppression products are planned for 2016 and we continue to invest in dust control products. Protecting air quality through continual reduction of dust is just one of our commitments to the communities near our operations and our employees to safeguard human health and the environment.
