Based on criteria, the prescribed instrument application may be flagged for a more detailed ‘secondary screening’ to determine if the activity associated with the application is a significant drinking water threat. If yes, the appropriate standard operating policy is applied. As legally required, where a source protection policy that relies on a prescribed instrument to prohibit an activity that is a significant drinking water threat, the ministry is conforming to the policy by refusing to issue an instrument for the activity.

Policy Text:

To ensure the new discharge from a stormwater management facility does not become a significant drinking water threat within vulnerable areas where this activity would be a significant drinking water threat:

a. The Ministry of the Environment, Conservation and Parks shall prohibit the new discharge from a stormwater management facility within the Environmental Compliance Approvals process in the following areas as appropriate:.

i. In Wellhead Protection Area A;
ii. In Intake Protection Zone one One (1).

b. The Ministry of the Environment, Conservation and Parks shall ensure that the Environmental Compliance Approval that governs the new discharge from a stormwater management facility includes appropriate terms and conditions to ensure the activity does not become a significant drinking water threat when permitted in the following areas as appropriate:

i. In Wellhead Protection Area B where the vulnerability is equal to ten (10);
ii. In Wellhead Protection Area E where the vulnerability is greater than or equal to eight (8);
iii. In Intake Protection Zones Two (2) and Three (3) where the vulnerability is greater than or equal to eight (8);
iv. Where a Nitrate and/or Chloride Issue has been identified, in all Issue Contributing Areas except Wellhead Protection Area A.

The Environmental Compliance Approval should include, as a minimum, water quality monitoring measures and reporting annually to the Ministry of the Environment, Conservation and Parks, as appropriate. Where there is a Nitrate, and/or Chloride Issue, groundwater and/or surface water quality shall be monitored for Nitrate and Chloride, respectively.

Monitoring Text:

(RW-CW-1.12) Where the Source Protection Plan policies require a Provincial Ministry to undertake an activity under the Environmental Compliance Approval process or review, issue or amend a Prescribed Instrument, the applicable Provincial Ministry should:

a. Provide a copy of the Prescribed Instruments to the Regional Municipality of Waterloo;
b. Provide a written report to the Region of Waterloo and the Source Protection Authority summarizing where Prescribed Instruments have been issued and/or amended and for each instrument a summary of the conditions included for source protection purposes.
