Has the institution implemented technologies or strategies to reduce the environmental impacts of snow and ice removal?:
A brief description of the snow and ice removal program, policy, or practice:
The salt used on the Western campus is treated with a magnesium chloride additive. The greatest benefit is that the salt continues to work in extremely cold temperatures. Normally, once the thermometer dips below minus six degrees Celsius, most road salts lose their strength and some areas may need to be salted several times to compensate. On the other hand, magnesium chloride-treated salt is effective up to minus 20 degrees Celsius, making a single pass often enough.
In addition, less harmful formulation containing potassium acetate and corrosion inhibitors (green and blue coloured material) are being used in and around campus. The colour is a product feature to let workers identify areas that have already been treated, eliminating the tendency to over-apply.
