The policy applies in all vulnerable areas where the establishment, operation or maintenance of a system that collects, stores, transmits, treats or disposes of sewage is a significant drinking water threat, in particular:

combined sewer discharge to surface water (existing activity)
sewage treatment plant bypass discharge to surface water (existing activity)

Municipalities shall give due consideration to establishing or continuing programs that separate combined sewers, as much as is feasible, to alleviate the amount of wastewater transported to the wastewater treatment plants.

An initial review shall be completed within three years of the effective date of the Source Protection Plan.

Monitoring policy MP-19 applies.

MP-19: Municipalities shall, by February 15 each year, provide to the local Source Protection Authority a brief summary report for the preceding calendar year that gives information on the activities taken toward implementing the policy.
