The policy applies in all vulnerable areas where the establishment, operation or maintenance of a septic system would be a significant drinking water threat (existing activity).
The policy applies to approvals from the Ministry of the Environment and Climate Change related to the establishment, operation or maintenance of an on-site sewage system as regulated under the Ontario Water Resources Act.
It is recommended that the Ministry review all Environmental Compliance Approvals for on-site sewage systems to determine whether:
a) the system contains design standards that provide reductions in the level of Nitrogen and Phosphorus in the treatment unit effluent;
b) the conditions include requirements for an emergency plan in the event of a failure of the system; and
c) the conditions include requirements for onsite monitoring to ensure that the system is functioning as designed and require the proponent to have the system inspected regularly using a standard equal to or greater than the inspection protocols of the “On-Site Sewage Maintenance Inspection” document dated March 2011 as amended from time to time, developed by the Ministry of Municipal Affairs and Housing.
