Cascades Canada ULC - Environmental Compliance Approval (waste)

Cascades Canada ULC, Trenton Containerboard Mill is applying to the Ministry of the Environment, Conservation and Parks (MECP) to amend existing Environmental Compliance Approval (ECA) No. A360205 for the processing of waste black liquor solids remaining from the pulp and paper manufacturing operations formerly conducted at the Mill, located at 300 Marmora Street, Trenton, Ontario.

The company has an existing ECA for the temporary storage of black liquor (by-product of the pulp and paper manufacturing process) in an on-site lined storage lagoon (ECA No. A360205). While the mill was operational, black liquor was sold as a product to third parties. As a result of the storage of black liquor in the lagoon, a black liquor precipitate (sludge) has accumulated within the lagoon. The Mill is no longer operating and as part of decommissioning of the lagoon, Cascades proposes to process the sludge as a non-hazardous solid waste and transport the waste to an off-site MECP-licensed waste disposal site.

The waste processing will occur within the Mill property using existing Mill equipment and facilities. The proposed operating hours for waste processing are 7 am to 7 pm, daily. Cascades expects that most of the processing will occur Monday to Friday; however, weekend work may be necessary based on the requirements of the disposal site.
