Within a WHPA-Q1 where the taking of water from an aquifer is or would be a significant drinking water threat, the MOE is encouraged to adopt and fund the on-going maintenance of the Tier 3 numerical models. The on-going maintenance of the Tier 3 numerical models includes:

1) Supporting environmental monitoring efforts to address data gaps and improve simulations of cumulative impacts; and,
2) Incorporating new information as appropriate into the Tier 3 models to provide decision makers with a tool to make informed water management decisions, and to ensure the activity ceases to be or does not become a significant drinking water threat.

MON-4: By February 1 of each year, Provincial Planning Approval Authorities shall report to the local source protection authority on the steps taken in the previous calendar year to implement the significant threat policies and recommendations, where appropriate.
