Scientists regularly test air quality to determine if mining activities at the Ekati mine, such as blasting, construction, and operating diesel generators and vehicles, are affecting air quality.
We monitor air quality annually and issue an Air Quality Monitoring Report every three years which discusses various aspects of air quality. The Air Quality Monitoring Report includes results of snow and lichen monitoring.
Air quality monitoring stations sample air for tiny particles, dust, sulphur dioxide, and nitrogen dioxide year-round. The sampling results from 2014 were almost always within government guidelines. The quality of snow and lichen samples was slightly lower than that of 2008 and 2011, but higher than that of 2005.
Results from the 2012 to 2014 Air Quality Monitoring Program suggested that our efforts to mitigate the effects of the mine on air quality are effective.
Dominion Diamond is committed to the continual improvement of its environmental practices. To ensure we are making progress in the area of dust management, the company committed to conducting a pilot study in 2015 comparing the effectiveness of various dust suppression products. The results of that study showed that a product called EnviroKleen can work in the harsh conditions at Ekati to reduce dust from the roads. We are continuing with a larger project in 2016 and 2017.
