In the Callander Issue Contributing Area, where the threat could be significant, the following existing and future activities are designated for the purpose of specifying certain conditions to be placed on a Nutrient Management Act instrument:

The application of agricultural source material

The storage of agricultural source material

The application of non-agricultural source material

The handling and storage of non-agricultural source material

The application of commercial fertilizer

The use of land as an outdoor confinement area or farm-animal yard.

Where the threat from any of the activities listed above would be significant and a Nutrient Management Plan, Nutrient Management Strategy, and/or Non-Agricultural
Source Materials Plan is required, the instrument should include appropriate terms and conditions that demonstrate that best management practices
related to limiting and/or attenuating phosphorus have been implemented in the plan or strategy to meet the objectives of the Source Protection Plan (SP
Plan). All existing instruments shall be updated within two years of the date the SP Plan takes effect to
demonstrate that best management practices related to limiting and/or attenuating phosphorus have been implemented in the plan or strategy to meet
the objectives of the SP Plan.
