Air & Noise Permit for Concrete Plants in Bowmanville
Official title: St. Marys Cement Inc. (Canada) operating as CBM Ready Mix - Environmental Compliance Approval (air)
A concrete company wants approval to operate three ready-mix batching plants on Bowmanville Avenue. The plants would release dust particles, silica, and trace metals into the air. Ontario's environment ministry is deciding whether to issue the permit.
Why This Matters
Live or work near 410 Bowmanville Avenue? These plants would release dust and silica particles into your neighbourhood air. Silica dust can cause serious lung problems with long-term exposure. Noise from operations could also affect nearby residents.
What Could Change
If approved, CBM Ready Mix could operate three concrete batching plants at this location. The permit would set limits on dust, silica, and metal emissions. Conditions may require pollution control equipment like baghouses to capture particles.
Key Issues
- Should this facility be approved to release particulate matter and silica into the air?
- Are the proposed emission controls adequate to protect nearby residents?
- What noise impacts will the operations have on the surrounding area?
How to Participate
- Review the proposal details on this consultation page. Note the list of contaminants that would be released.
- Submit your comments through the Environmental Registry by the December 19, 2025 deadline, or email enviropermissions@ontario.ca.
