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 shall be prohibited under the following conditions:

the snow is stored at or above grade and the storage area is:

more than 1 but not more than 5 hectares; or
more than 5 hectares

the snow is stored below grade and the storage area is:

- at least 0.01 but not more than 0.5 hectares; or
- more than 0.5 but not more than 1 hectare; or
- more than 1 but not more than 5 hectares; or
- more than 5 hectares.

Therefore, the storage of snow is designated for the purposes of s.57 of the Clean Water Act.

Notwithstanding clause (A.1) above, the storage of snow is not prohibited 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.

With regards to any snow storage sites existing as of the effective date of the Source Protection Plan, the policy takes effect eight months following the effective date of the Source Protection Plan.
