The existing and future application, handling and storage of commercial fertilizer to land is designated for the purposes of Section 58 of the Clean Water Act, and therefore requires a risk management plan for those not phased in under the Nutrient Management Act, where the vulnerability score is less than 10. The risk management plan, at a minimum, will be based on contemporary standards and shall require:

Application
1) all fertilizers to be applied using best agronomic practices based on the advice of a certified crop advisor;
2) that soil tests (NPK) be conducted; and
3) that proper farm practices regarding crop rotation be applied, as appropriate.

Handling and Storage
1) liquid fertilizer to be stored in double-walled tanks or secondary containment facilities, with collision protection;
2) dry fertilizer to be stored under cover on impervious floor surfaces with no drainage outlets
so that the application, handling and storage of commercial fertilizer 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.
