Thank you, Mr. Chairman. The current calcium program on the highway system in the Northwest Territories provides dust control treatment on a majority of the gravel system. However, it does not cover the entire system.
In some parts of the system where there are lower traffic volumes, those sections are not treated. There are sections on the Liard Highway, for example, and some sections of the Dempster Highway that do not receive treatment.
The criteria at this point sets it at a traffic volume level and, if I recall correctly, it is 50 vehicles per day. At this point, there are a number of sections of the system that do not receive that level of traffic. However, within those sections there are dust-free zones. Calcium is applied within those sections to provide opportunities for passing in a dust-free environment. Thank you, Mr. Chairman.
