ALTERNATIVES TO SODIUM CHLORIDE AS A SNOW AND ICE CONTROL AGENT FOR USE ON CITY OF OTTAWA COLLECTOR ROADS

The City of Ottawa has explored a variety of alternatives to sodium chloride for deicing, including ice resistant pavements, calcium chloride mixtures, and urea. None of these alternatives has proven to be successful. Other jurisdictions have tried a "no salt" policy, but have found that driving conditions continued to deteriorate throughout the winter and that the economic costs of not salting far exceed the costs of salting. The pursuit of alternatives to sodium chloride has grown dramatically in recent years, and several U.S. state governments, provincial governments (including Ontario) and private agencies have examined various alternatives. Two in particular appear to be most promising: Calcium Magnesium Acetate (CMA) and Sodium Formate (NaFo). It is recommended that the City conduct a series of field trials to evaluate the relative effectiveness of sodium chloride, CMA and NaFo. The results of these field trials are summarized in a follow-up report "1987-1988 City of Ottawa De-icer Field Trials" (TRRL)
