If you want some technical information about salt and other winter maintenance practices, try the following listserv. It may be too much, but you will see a LOT of different ideas. Also, conferences and references are posted regularly, so you may find more about it.

This is not an easy problem to solve, since safety requires that roads and lots be maintained. So far, there has been no "silver bullet". For example, potassium acetate, which is touted as friendlier to the environment, is very expensive and increases the rate of concrete breakdown. (Replacing concrete and bridges more often does not seem to be particularly sustainable!) Sand can be used and captured, but creates PM10 problems in urban areas. In Colorado, we try to use a variety of deicers to meet different weather conditions. We also use metered sand/salt dispensers so that the mountain roads are not over-sanded. Good equipment and well-trained operators seem to be the most important factor in using enough, but not too much material.

Interestingly, the main utilities in Colorado that are using rebates are the larger water utilities. Denver Water has offered different types of rebates over the past several years, including for high-efficiency washing machines. The rebates are for water savings, but happen to help with electrical savings, too. Maybe the electrical and water utilities should work together for mutual benefit...
