Iogen Corporation - Environmental Compliance Approval (air)

This proposal is for an amendment to the Limited Operational Flexibility for an Environmental Compliance Approval (air & noise) No. 4467-AP9RVX 3 for Iogen Corporation, an integrated fermentation production and cellulosic ethanol manufacturing facility producing cellulosic ethanol and liquid products, located in the City of Ottawa, Ontario.

The emission sources from the manufacturing and associated processes that discharge to the air include combustion equipment; utilities; refining (concentration, purification, modification); mixing and blending; as well as fumehoods, scrubbers, and baghouses. The amendment includes expansion of its operations to include biogas and biomethane production, in addition to its existing cellulosic ethanol production.

Emissions to the air from this facility include:

• odour
• ethanol
• carbon monoxide
• carbon dioxide
• acrolein
• nitrogen oxides, and
• particulate matter

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.
