Thank you, Madam Chair. We actually use quite a bit of sand in our maintaining friction on highways. When temperatures are between zero and minus 15 or minus 20, it’s most effective to use sand and salt in combination. The salt will help to actually take the ice off of the surface and allows the salt that is applied to stick to the surface a little longer. Once you get below minus 20 or minus 25, then salt becomes ineffective and then we use sand. The challenge there is getting the sand to stick to the surface of the road. We’ll put sand on in the morning, and if it’s cold enough and with enough traffic, then all the salt will be blown off the road by the vehicles that
use it, so we’ll have to come back and keep applying sand. That’s just the reality of life and doing highway operations in the North. But it is effective to use both a combination of sand and salt in our O and M practices.
