A stormwater management facility that is not governed by a Prescribed Instrument (Certificate of Approval or Environmental Compliance Approval) is designated for the purpose of Section 58 of the Clean Water Act, requiring a Risk Management Plan in the following situations:

An existing stormwater management facility that is a significant threat as described in Appendix B
A future stormwater management facility that would be a significant threat as described in Appendix B located within the:
Intake Protection Zone with a vulnerability score of 8, 8.1 or 9;
Wellhead Protection Area A; (under the exemption described in policy SEW-9-LB-PI/PA-MC); and
Wellhead Protection Area B; with a vulnerability score of 10.

Where the Risk Management Official considers it appropriate, Risk Management Measures will require that a new stormwater management facility be built to Enhanced Level Protection Standards as described in the Stormwater Management Planning and Design Manual, MOE 2003. Risk Management Plans for existing stormwater management facilities shall be established within three years from the date the Source Protection Plan takes effect.
