Jungbunzlauer Canada Inc. - Environmental Compliance Approval (sewage)

This proposal is to amend ECA#4379-DB8JUE, issued on November 28, 2024, to Jungbunzlauer Canada Inc. for approval of sewage works serving the citric acid production facility (JBL Citric Plant), the corn-derived glucose manufacturing facility (JBL Glucose Plant), and the xanthan gum production facility (JBL Xanthan Gum Plant) located at 1555 Elm Street, in the City of Port Colborne, Regional Municipality of Niagara.

The previously approved sewage works were designed for the collection, transmission, treatment, and disposal of process wastewater and once-through non-contact cooling water from the JBL Citric Plant, JBL Glucose Plant, JBL Xanthan Gum Line, and the associated stormwater runoff.

The proposed amendment application is for approval to expand the existing sewage works to accommodate an increase in production across JBL’s mixed product campus to meet market demands. The proposed amendments are for approval of:

• addition of a seventh, eighth, and ninth aeration basin
• addition of a fourth and fifth clarifier
• addition of a second gravity thickener
• an increase to the treated process water discharge from JBL’s mixed product campus from the existing maximum one-day discharge rate of 35,000 cubic metres per day to 45,000 cubic metres per day. The annual daily average flow will increase from 28,000 cubic metres per day to 35,000 cubic metres per day
• an increase to the discharge of once-through non-contact cooling water from up to 233,500 cubic metres per day to 520,000 cubic metres per day
• addition of a second effluent diffuser discharging to the Welland Canal
• a new stormwater management system, serving the Xanthan Gum facility, consisting of collection ditches, detention pond of 2,090 cubic metres capacity, and oil and grit treatment system, discharging ultimately to the Welland Canal
