Where the future taking of water from an aquifer without returning it to the same aquifer would be a significant drinking water threat, Planning Approval Authorities shall only permit new development or site alteration where it has been demonstrated that any increase in water demand beyond the allocated demand is sustainable as determined by the MOE in accordance with the Source Protection Plan and Ontario Water Resources Act.

MON-1: By February 1 of each year, municipalities shall report to the local source protection authorities on the steps taken in the previous calendar year to implement these significant threat policies and recommendations, where appropriate.
