The policy applies in all vulnerable areas where the application of road salt is or would be a significant drinking water threat (existing activity or future activity).

Establishment of a Risk Management Plan is required. 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 200 square metres or 8 parking spots; 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;
b) employ the latest winter maintenance technologies;
c) 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.

Notwithstanding the above, a Risk Management Plan will also be required for any municipal properties where the activity is or would be a significant drinking water threat.

All locations for Risk Management Plans for existing activities shall be inventoried within three years and plans established within five years of the amendment to the Source Protection Plan taking effect.

Monitoring policies MP-24 and MP-25 apply.

MP-24: The Risk Management Official shall, by February 1 each year, provide to the local Source Protection Authority a summary report for the preceding calendar year that gives an inventory of the number of locations where Risk Management Plans will be negotiated. This inventory must be completed by February 1 of the year following the third anniversary of the effective date.

MP-25: The Risk Management Official shall, by February 1 each year, provide to the local Source Protection Authority a summary report for the preceding calendar year that gives information on the number of plans, a summary of the plans and a summary of any violations.
