Original proposal
Proposal details
Application has been made by Dufferin Aggregates, A Division of CRH Canada Group Inc. to amend the current site plan. The change would remove a portion of the 15-metre southern setback. This change would allow for the pond to connect with the adjacent proposed below water expansion application (application #626561). Application #626561 considered the removal of the setback on Licence 608621 and anticipated the two quarries would connect to form a single pond. A decision has not yet been made on application #626561. This proposal and the expansion application are being considered by the ministry concurrently.
