Dust Management in the Elk Valley

We take extensive measures to monitor and manage dust at our operations and are working to identify new methods to improve dust management and air quality.

Air Quality and Dust Management

Managing air quality is critical to people, communities and the environment. Teck understands that dust generated from our operations is visible from communities in the Elk Valley. We are deploying known effective dust mitigations, and looking at other innovative mitigations and monitoring systems to drive continued improvement at our operations. We are gaining ground, but recognize that more work is needed. We value your input and have included your feedback into our practices.


  • Teck is continuously improving dust management practices by working on new and innovative solutions, focusing on minimizing and managing dust generation.

  • Teck is excited to continue our partnership with the Massachusetts Institute of Technology (MIT) to explore various monitoring techniques to collect data in and around the mine and Sparwood. The data will inform mitigation activities at site. Learn more at http://senseable.mit.edu/cityscanner/

  • Elkview Operations is implementing full-scale use of an in-pit chemical suppressant to improve effectiveness of the water truck fleet, this is being considered by other Teck operations’ based on EVO success

  • Elkview Operation continues to investigate software to predict and determine dispersion of dust from its operations. This information will inform blasting practices and placement of mitigations such as water trucks, misters and mulch material.

 

The Socio-Community and Economic Effects Advisory Committee (SCEEAC) acts as a conduit for our Elkview Operations and the District of Sparwood to reach citizens and for citizens to reach Teck EVO and District of Sparwood. SCEEAC provides recommendations to Council and Teck for consideration with respect to implementing Elkview’s Baldy Ridge Extension Environmental Assessment Certificate Condition 21.

  • Water trucks are on site at all times to keep active road and pit areas wetted to minimize dust generation during above zero temperatures. Water trucks receive priority maintenance.

  • Hydro seeders are used to apply mulch and chemical suppressants to reduce dust from various locations around the mine site known for dusting ((i.e. lagoons, coarse coal refuse, clean coal stockpiles, high walls). Mulch has been proven to be effective at minimizing airborne dust due to wind.

  • Mister trucks, mister trailers or mister cannon systems are deployed throughout site, including high walls, spoils and blast areas. Watering these surfaces helps to prevent airborne dust caused by wind.

  • Chemical dust suppression is applied to roads and rail cars to prevent dust generation

  • Expedited reclamation of former mining areas, specifically targeting visible areas from the community of Sparwood, including the new 6 Mile Access Road, areas below the Baldy Ridge II pit and unclaimed areas of the Bodie spoil and areas of the Baldy Ridge VI spoil.

  • Elkview Operations continues to evaluate mine design and sequencing to reduce community impact. This includes blasting changes, bottom up spoiling.

  • Closing access, capping, and seeding portions of the Natal Spoil with coarse rock to reduce dust from fine surface material – IN PROGRESS

  • Focusing on material size and selective dumping to reduce fines on wind-affected spoils – PILOT COMPLETE

  • Implemented Trigger Action Response Plans (TARP) for ‘high’ and ‘excessive’ risk fugitive dust sources – COMPLETE/ONGOING 

  • Investigated the use of MicroPulse LiDAR to observe dust source generation and movement – COMPLETE

  • Teck formed a Dust Management Committee in 2016 comprised of Senior Management and currently leads a Regional Air Working Group encompassing all five mines in the Elk Valley. Under the working group, operations are working together to share and develop best management practices, robust monitoring systems and to carry out open and transparent community engagement on this issue.

  • All Teck operations participate in a valley-wide ambient air-monitoring program, consisting of eight continuous air quality monitoring stations in and around the Elk Valley. These stations are maintained and assured by a qualified third party.  This data is evaluated and reported to the BC Ministry of Environment.

  • The Sparwood monitoring results are reported to the District of Sparwood and to the community annually.

  • Teck is evaluating the Regional Air Monitoring Network to ensure the network remains suitable and relevant.

  • Live monitoring via intermittent and real-time cameras directed at operations to help personnel understand what site looks like from the community and to aid dust management planning.

Elk Valley Dust Monitoring Stations

Fine Particulate Classification

PM2.5: a particulate 2.5 microns or smaller in diameter.
The Provincial Government’s objective is 25 micrograms per cubic meter.

PM10: a particulate 10 microns or smaller in diameter.
The Provincial Government’s daily objective is 50 micrograms per cubic meter.

TSP: the overall Total Suspended Particles.
The Provincial Government’s daily objective is 120 micrograms per cubic meter.

Elk Valley Operations Blasting Schedule

Teck may conduct daily blasting at our Operations. We monitor wind direction and plan our blasts for when favourable weather conditions exist.

Elkview Operations blasts are scheduled for 12:30 p.m. or 4:30 p.m., there are minimal instances of blasting outside of this timeslot.

Greenhills Operations blasts are scheduled between 1:00 p.m. and 1:30 p.m., there are minimal instances of blasting outside of this timeslot.

Line Creek Operations blasts are scheduled for 2:00 p.m. or 5:00 p.m., there are minimal instances of blasting outside of this timeslot.

Fording River Operations blasts are scheduled for 1:30 p.m. but blasting times can vary between 10:30 a.m. and 4:00 p.m.

Fording River Operations may blast more than once per day.

Coal Mountain Operations has ceased blasting as the site prepares to transition to care and maintenance.


Feedback

We welcome feedback from the community to help us to understand whether our mitigation measures are working, and if there are new issues that we need to address. Feedback can be left anonymously but if you leave your contact details we will always follow up with a response. We welcome your questions, feedback and suggestions on an ongoing basis.
