An increasing number of agencies have to adapt their winter maintenance operations because of environmental concerns over chlorides in groundwater, rivers, lakes, and streams. In this session, we will examine how chlorides can impact the environment and then focus on the methods identified as being appropriate to mitigate these impacts. Specifically, these methods are taken from various variance documents that agencies must commit to in their winter maintenance operations. As such, they are to some degree "approved ", and implementing them (if you are not already doing so) will allow you to "enviroproof " your winter maintenance.
