PINPOINTING YOUR ENVIRONMENTAL WEAK SPOTS

This article outlines the steps winter highway maintenance crews must take to protect the environment from the high levels of salt and deicing chemicals that are necessary to keep roads clear. The article looks at the general concept of “Sensible Salting” and relates that while the proper use of salt and deicers can result in a significant reduction in winter crashes, this winter maintenance technique can have highly detrimental environmental effects when distributed in a condensed area such as a roadway. Some environmental factors that involve salt are the species of plant and soil types that are sensitive to chloride. In order to prevent unneeded maintenance of these plants in the unlikely event that they survive salt-runoff, the article recommends that highway crews use plants that are more chloride tolerant. The article also recommends that engineers perform a survey of affected roadways to determine where there is evidence of salt damage. Upon the completion of such a survey, engineers can form a plan to divert chlorinated runoff into less sensitive areas.
