With the exception of personal domestic use the existing and future application of road salt 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 include terms and conditions to require a reduction in salt application, and comply with contemporary standards to ensure the application of road salt 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.
