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 can be demonstrated that any increase in water demand can be demonstrated on a sustainable basis 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.
