Discovery Kidd Creek Inc. - Environmental Compliance Approval (air)

This proposal is for an Environmental Compliance Approval with Limited Operational Flexibility (air and noise) 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 Discovery Kidd Creek Inc., a mining and mineral processing facility producing copper-zinc ore located in Timmins, Ontario.

The application includes all sources at the facility, including combustion equipment, dust collectors, welding operations, cooling towers, ventilation raises, fugitive roadway emissions, material handling emissions, and wind erosion.

Emissions to the air from this facility include:

• particulate aatter
• nitrogen oxides
• sulphur dioxide
• manganese, lead
• cadmium
• chromium (VI)

The Environmental Compliance Approval with Limited Operational Flexibility (air and noise), 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 and noise). 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.
