Decision details
This decision concerns an amendment to Environmental Compliance Approval (ECA) No. 6991-BRJQVM for upgrades to the sewage works serving Lactalis' dairy products manufacturing facility located at 490 Gordon Street, Winchester, in the Township of North Dundas, United Counties of Stormont, Dundas and Glengarry, Ontario.
Domestic sewage generated at the facility is collected separately and discharged to the municipal wastewater treatment system. Treated effluent from the facility's wastewater treatment plant (WWTP) is discharged to the Annable Drain, which traverses the Lactalis property.
The amendment authorizes an increase in the rated capacity of the WWTP from 1,400 m³/day to 2,400 m³/day, with a maximum annual treatment volume of 876,000 m³. The increased capacity will be achieved through a combination of wastewater treatment system upgrades that have already been completed and revised effluent discharge provisions to the Annable Drain. The approval includes conditions respecting effluent quality and minimum dilution requirements to ensure the protection of the receiving watercourse.

Start the process to appeal
If you’re an Ontario resident, you can start the process to appeal this instrument decision.
First, you’ll need to seek leave (i.e. get permission) from the relevant appellate body to appeal the decision.
If the appellate body grants leave, the appeal itself will follow.

To seek leave to appeal, you need to do these three things:
- prepare your application
- provide notice to the minister
- mail your application to three parties

Original proposal
Proposal details
This proposal is for an amendment to the ECA 6991-BRJQVM to upgrade the sewage systems servicing Lactalis' dairy products manufacturing plant located at 490 Gordon Street, in Winchester, Township of North Dundas, United Counties of Stormont, Dundas and Glengarry, Ontario.
Domestic sewage at the manufacturing plant is segregated and discharged separately to the Municipal treatment plant. Treated effluent from the works discharges to the Annable Drain, which flows through the Lactalis property.
The proposed rated capacity increase for the Waste Water Treatment Plant to 2,400 cubic metres per day, or 876,000 cubic metres per year, is meant to be accommodated through a combination of completed wastewater treatment upgrades, and increased discharge to the Annable Drain within existing ECA restrictions for effluent quality and dilution rates.
