Notice: Biosolids Management Study

Thursday, June 9, 2022

In June, 2015 the City of Sault Ste. Marie completed a Schedule B Class Environmental Assessment to address challenges in mitigating odours and disposing of biosolids in the working face at the landfill.
At the conclusion of the study process there was a clear preference to process the biosolids using composting or alkaline stabilization with the proposed facility to be constructed at the landfill.  A final report (ie: Biosolids Management Study) was prepared which summarized the input received throughout the study and rationalized the design decisions made.
Since the completion of the final report, the City proceeded with a Request for Proposal Process (RFP) to select a preferred alkaline stabilization or composting technology vendor.  That RFP process resulted in the receipt of two vendor submissions each proposing a distinct composting methodology. No submissions were received for alkaline stabilization.  Furthermore, since the completion of the final report, the Province introduced the Food and Organic Waste Policy (Policy) which, in part, sets a target for larger municipalities in Northern Ontario for a “50% waste reduction and resource recovery of food
and organic waste generated by single-family dwellings in urban settlement areas”. This policy mandates the City of Sault Ste. Marie to collect and process Source Separated Organics (SSO) by approximately
An ADDENDUM has now been completed to the Biosolids Management Study Report to address the processing of SSO in addition to biosolids at the proposed facility.  The addendum provides details on the proposed changes relative to the conceptual design documented in the original Report.
By this Notice, the Addendum is being placed on the public record for review in accordance with the requirements of the Municipal Class Environmental Assessment.  Subject to comments received as a result of this Notice, the City intends to incorporate the proposed changes into the design of this project.
The project addendum is available at the locations noted below or on the City’s website at the following address:
Interested persons should provide written comment to the Municipality or the Consultant via email or hardcopy at either of the addresses noted below within 30 calendar days from the date of this Notice.
