Air and Noise Permit for Mobile Crushing Plant - Teranorth Construction
Official title: Teranorth Construction & Engineering Limited - Environmental Compliance Approval (air)
Teranorth Construction wants approval to operate a portable rock crushing plant anywhere in Ontario. The equipment includes crushers, a screener, and diesel engines that emit particulate matter, silica dust, and exhaust gases. It could run 24/7, year-round.
Why This Matters
This is a mobile facility that could operate near any community in Ontario. If it sets up near you, you'd hear the noise and breathe the dust. The permit allows round-the-clock operation with no seasonal limits.
What Could Change
If approved, Teranorth gets a blanket permit to crush aggregate anywhere in Ontario. The approval would set limits on particulate matter, silica, and noise emissions. Operating conditions may restrict hours or require dust controls.
Key Issues
- Should a mobile crushing plant be allowed to operate 24/7 year-round?
- Are the proposed emission controls adequate for particulate matter and silica dust?
- What noise limits should apply when operating near communities?
