The following is an MECP update that was received by the City of Hamilton September 11, 2023.
The ministry continues to ensure GFL is taking all available and feasible steps to mitigate the odour impacts from the GFL Stoney Creek Regional Facility (SCRF) landfill. Ministry Environmental Officers continue to attend the SCRF and surrounding residential areas daily in response to the odour complaints.
GFL is continuing to take the following actions to address odours from leachate at the site:
- GFL has now commenced the operation of a treatment control system at the interim leachate pump station to mitigate odours during the processing of leachate prior to discharge to the sanitary system. The treatment system is a wood biofilter that will treat the odours generated from the leachate in the pumping station which is located at the southeast corner of the SCRF.
- GFL has deployed an odour neutralizing system (fan and misting systems) throughout the site in four locations.
- The company continues to truck exposed leachate off site for disposal to help accelerate the removal of the excess leachate at the site.
- Any exposed leachate on-site is being treated to mitigate the odours.
GFL continues to work with their consultant to assess all other available technologies to mitigate offsite odours.
The ministry initiated air monitoring around the landfill. The air monitoring results have now been received. The monitoring campaign confirmed the presence of odorous compounds on multiple occasions, however all measurements were below the relevant air standards. The ministry has now met with Hamilton Public Health Services to discuss and have shared the results for their health interpretation.
The ministry will be coordinating additional air monitoring campaigns in response to the community’s concerns and will ensure Environmental Officers are responding to the site regularly to assess any odour impacts and follow up with GFL to ensure that they are taking all possible steps to minimize odour impacts.
