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

The storage of snow may only occur in accordance with an approved Risk Management Plan under the following conditions:
the storage of snow where the snow is stored at or above grade and the storage area is at least 0.01 but not more than 0.5 hectares; or
the storage of snow where the snow is stored at or above grade and the storage area is more than 0.5 but not more than 1 hectare.
Establishment of a Risk Management Plan is required. Therefore, the storage of snow is designated for the purposes of s.58 of the Clean Water Act.

As a minimum, the Risk Management Plan shall address:
1) runoff management;
2) implementation of best management practices;
3) consideration of alternative sites outside of the affected vulnerable area

Notwithstanding clause (A) and (B) above, a Risk Management Plan is not required where:
the snow storage constitutes the snowbanks immediately adjacent to a travelled roadway; and
the snow storage is contained within the road allowance for the travelled roadway.
The Risk Management Plan shall be renewed every five years or at the discretion of the Risk Management Official.
All locations for Risk Management Plans for existing activities shall be inventoried within three years and plans established with five years of the effective date of the Source Protection Plan.

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.
