Rexdale Building Supply Ltd. - Environmental Compliance Approval (air)

The proposal is for an amendment to Environmental Compliance Approval 9502-AKPJSW (air & noise) for Rexdale Building Supply Ltd., a ready-mix concrete batching plant located at 19 Taber Road, in the City of Toronto, Ontario.

Emissions sources at the facility include:

• two baghouse dust collectors controlling emissions from two storage silos, and
• fugitive emissions from the delivery, storage and transfer of materials associated with the ready-mix concrete batching operations

This amendment is to reflect the addition of a new loading point dust collector and the replacement of the natural gas fired boiler.

Contaminant emissions from the atmosphere include:

• particulate matter
• portland cement
• slag
• respirable crystalline silica (quartz)
• nitrogen oxides
