The existing and future storage and application of agricultural source material to land is designated for the purposes of Section 58 of the Clean Water Act and therefore requires a risk management plan where the vulnerability score is less than 10 and the activities are or would be significant drinking water threats. The risk management plan, at a minimum, will be based on contemporary standards, reflect appropriate nutrient management practices, and ensure the activity 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.
