Proposal details

This proposal is for an Environmental Compliance Approval with Limited Operational Flexibility (air) which replaces all the current Environmental Compliance Approvals for air at this facility and includes the addition of new, or historically unapproved, sources for all emissions from CRH Canada Group Inc., a cement manufacturing facility located in the City of Mississauga, Ontario.

The application includes all sources at the facility, including:

  • stacks and mills
  • crushers
  • loading and transferring emissions
  • baghouses
  • natural gas material dryers
  • separators
  • diesel generators

Emissions to the air from this facility include:

  • suspended particulate matter
  • aluminum oxide
  • barium
  • calcium
  • chromium compounds (metallic, divalent and trivalent forms)
  • cobalt
  • nickel and nickel compounds
  • potassium
  • silicon
  • tin

The Environmental Compliance Approval with Limited Operational Flexibility (air), when issued, permits modifications to the facility subject to limits on operational flexibility that include a production limit for the facility to be specified on the Environmental Compliance Approval with Limited Operational Flexibility (air).

The limited operational flexibility conditions have an expiry date. The company will be required to make an application for amendment at that time to renew these conditions
