The application of road salt may only occur in accordance with an approved Risk Management Plan and is therefore designated for the purposes of s.58 of the Clean Water Act, where the following applies:
a) Where the activity is or would be a significant drinking water threat;
b) Salt is or could be applied to the property;
c) The salt application area is equal to or greater than 1,000 square metres and
d) The property is used for any land uses except residential consisting of four units or fewer.
As a minimum, the Risk Management Plan shall:
a) follow best management practices consistent with those used across Canada, and
b) identify actions to improve practices in the general use of road salts
The Risk Management Plan shall be renewed every five years or at the discretion of the Risk Management Official. Risk Management Plans for existing activities shall established within five years of the amendment to the Source Protection Plan taking affect. The Risk Management Official may accept a municipal Salt Management Plan in lieu of a Risk Management Plan.
