The policy applies in all vulnerable areas where use of land as an outdoor confinement area or a farm-animal yard is or would be a significant drinking water threat (existing activity or future activity).

The policy applies to the following provincial instruments:
- nutrient management strategies under the Nutrient Management Act

A nutrient management strategy shall satisfy the following provisions:
1. The nutrient management strategy shall not permit the expansion of an existing outdoor confinement area or a farm-animal yard beyond the number of square metres existing as of the effective date of the Source Protection Plan in all WHPA-A vulnerable areas where the activity is or would be a significant drinking water threat (existing activity or future activity); and
2. The nutrient management strategy shall not permit the establishment of a new outdoor confinement area or a farm-animal yard in all WHPA-A vulnerable areas where the activity would be a significant drinking water threat (future activity).

The Ministry of the Agriculture, Food and Rural Affairs shall:
A. review all existing nutrient management strategies in all vulnerable areas where the use of land as an outdoor confinement area or a farm-animal yard is a significant drinking water threat (existing activity); and
B. determine whether the approvals as described in clause (A) contain appropriate terms and conditions and require adequate measures to be in place to satisfy clauses (1) and (2) above; and
C. where the Ministry is of the opinion that the terms, conditions and measures contained in an approval as described in clause (B) are not adequate, cause such amendments to be made to the nutrient management strategy so as to satisfy clauses (1) and (2) above.

Existing approvals shall be reviewed within three years of the effective date of the Source Protection Plan. Where amendments are deemed necessary, the existing approval shall be amended within 12 months of the review.
