To ensure that an existing onsite sewage system and/ or onsite sewage system holding tank, with a design flow of greater than 10,000 Litres per day and regulated under the Ontario Water Resources Act, ceases to be a significant drinking water threat, where this activity is a significant drinking water threat, the Ministry of the Environment, Conservation and Parks shall review and, if necessary, amend Environmental Compliance Approvals to incorporate terms and conditions that, when implemented, ensure that these onsite sewage systems are managed to reduce the risk to drinking water sources.

Where the Source Protection Plan policies may result in amendments to an existing Prescribed Instrument or the issuance of a new Prescribed Instrument, the applicable ministry shall provide a summary of any 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.
