Air Emissions Permit Amendment for Cabot Carbon Black Plant - Sarnia

Official title: Cabot Canada Ltd. - Environmental Compliance Approval (air)

Open Regulations & Permits Environment & Climate
Cabot Canada wants to swap out two old boilers for a rental boiler at their carbon black manufacturing plant in Sarnia. The facility releases pollutants including nitrogen oxides, benzene, and particulate matter. Ontario's environment ministry is deciding whether to approve this equipment change.

Why This Matters

Live near Sarnia's industrial corridor? This plant already releases benzene and other pollutants into the air. Equipment changes can affect local air quality. If you're concerned about emissions in Chemical Valley, this is your chance to weigh in.

What Could Change

If approved, Cabot can install a rental boiler to replace their existing #1 and #2 Coil Tube boilers. The permit sets production limits and operational flexibility conditions with an expiry date. The company must reapply when those conditions expire.

Key Issues

  • Should the boiler replacement be approved given current air emissions from the facility?
  • Are the proposed operational flexibility limits adequate to protect air quality?
