The handbook will also help you under- <br />stand when to use and when not to use these tools and prac- <br />tices. In addition, it encourages progressive changes in snow <br />and ice control practices that will help you reduce salt /sand <br />use and environmental impacts while meeting the safety and <br />mobility needs of roadway users. <br />Improved practices such as anti- icing, prewetting, and pre - <br />treating are emphasized in this field handbook. Also included <br />are standard best practices expected in a quality snow and ice <br />control program. <br />Throughout the field handbook you will find environmental <br />tips shown with this fish symbol )' * . These tips are provid- <br />ed to help you reduce environmental impacts from snow and <br />ice control operations. <br />A blanket approach will not work for the broad range of condi- <br />tions Minnesota experiences; different strategies are needed <br />for different regions and different conditions. We encourage <br />you to continue to test, document, and refine the practices <br />from this field handbook. <br />Less material on <br />roads means less <br />material in lakes <br />and streams. <br />
