Highway Deicing Management

Effective management of highway deicing practices can lessen receiving water impacts associated with chlorides, sodium, and suspended solids. Recommended alternatives for modifying deicing practices include: (1) judicious application of salt and abrasives; (2) reducing application rates using sodium and calcium salt premixers; (3) using better spreading and metering, and calibrating application rates; (4) prohibiting use of chemical additives; (5) providing improved salt storage areas; and (6) educating the public and operators about the effect of deicing technology and best management practices.
