Decision details
expansion of sewage works for the collection, transmission and disposal of stormwater as well as spill containment works servicing a newly proposed battery energy storage system (BESS) facility and the existing transformer station located at 6531 Rutherford Road, City of Vaughan, which provide Enhanced Level Total Suspended Solids (TSS) removal.
The works consist of:
- The facility includes nine oil containment pits with individual storage capacities ranging from 2,501 L to 8,709 L of insulating transformer mineral oil. Each containment pit is equipped with a dedicated oil collection sump and sub-drainage system designed to collect and convey accumulated liquids within the containment area.
- Drainage from the site will be collected and conveyed through the proposed on-site swales to a dry pond designed to provide stormwater quantity control. The controlled discharge from the dry pond will be released through a riprap outlet located at the south property boundary. Following discharge, runoff will be conveyed via overland flow across the adjacent property before ultimately draining to Rainbow Creek.
