To ensure Existing or New onsite sewage systems with a design flow of greater than 10,000 Litres per day and regulated under the Ontario Water Resources Act cease to be or never become a significant drinking water threat, where this activity is, or would be, a significant drinking water threat, the MECP shall review and, if necessary, amend Environmental Compliance Approvals to incorporate terms and conditions that, when implemented, ensure that the activity ceases to be or never becomes a significant drinking water threat.

The terms and conditions may include, as appropriate, requirements for the proponent/applicant to undertake mandatory monitoring of groundwater impacts, contingencies in the event that drinking water quality is adversely affected, regular and ongoing compliance monitoring, mandatory system inspections at least every five (5) years, and upgrading of these onsite sewage systems to current standards, if necessary.

In addition, the terms and conditions may include the proponent/applicant to provide annual reporting to the Source Protection Authority and Municipality of any monitoring and inspection programs required and their results.

(WC-CW-1.12): Where the Source Protection Plan policies may result in amendments to a Prescribed Instrument or the issuance of a new Prescribed Instrument, the applicable ministry shall provide a summary of the actions taken the previous year to implement the policies and provide a written report summarizing this information to the Source Protection Authority by February 1st of each year.
