The Regional Municipality of Waterloo and Area Municipalities shall review and, if necessary, amend their Official Plans to require any development proposals for new storm water management facilities shall be subject to a study to assess impact and mitigation measures in accordance with the Regional Implementation Guideline for Source Water Protection Studies to the satisfaction of the Regional Municipality of Waterloo within the following areas:

i. In Wellhead Protection Area B where the vulnerability is equal to ten (10);

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