With the exception of personal domestic use, the existing and future storage of snow is designated for the purposes of Section 58 of the Clean Water Act, and therefore requires a risk management plan where the activity is or would be a significant drinking water threat within WHPA-A of the ICA. The risk management plan, at a minimum, will be based on contemporary standards, and shall ensure that the storage of snow ceases to be or does not become a significant drinking water threat.

MON-6: By February 1 of each year, risk management officials shall report annually to the local source protection authority with the information required in Section 65 of Regulation 287/07 related to the previous calendar year on the significant threat policies that designate an activity for the purpose of Section 58 risk management plans or Section 57 prohibition.
