Proposal details
This proposal is for a new Environmental Compliance Approval for industrial sewage works for Ontario Custom Aggregates Limited, located at 1151 Jigs Hollow Road, in West Montrose, Township of Woolwhich, Ontario.
This application is for the collection, transmission, treatment, and disposal of washwater from a new aggregate washing plant on the Jigs Hollow Pit property. The wash plant operation will consist of a closed-loop system with three ponds. Water will be taken from the Source Pond, where it will be used to wash aggregate. The run-off will drain to the Primary Settling Pond for settlement, followed by the Secondary Settling Pond for additional settling. Water will ultimately be directed back to the Source Pond to be re-used in a continuous cycle.
The ministry may require effluent monitoring for the discharge leaving the site.
