The emission sources from the manufacturing and associated processes that discharge to the air include dryers, filters, storage tanks, tail gas burners, an incinerator, vacuum systems, boilers, and other ancillary equipment. The amendment includes:

Emissions to the air from this facility include:
- nitrogen oxides
- particulate matter
- benzene
- carbon black
- hydrogen cyanide

The Environmental Compliance Approval with Limited Operational Flexibility (air & 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 & 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.
