York1 Environmental Waste Solutions Ltd., as general partner for and on behalf of York1 Environmental Waste Solutions LP - Environmental Compliance Approval (waste)

The subject property at 29831 Irish School Road in Dresden, Ontario is a 35-hectare property. The subject property has been used as an approved landfill site and an approved waste processing/transfer site. The subject property holds an existing Environmental Compliance Approval (ECA) No. A021304 for a 35-hectare waste disposal site with an 8-hectare landfilling area. The application is to amend ECA No. A021304 to re-open and operate the dormant landfill to meet current environmental standards.

The application is for an amendment to the existing waste disposal ECA No. A021304 for an 8-hectare landfill for the disposal of non-hazardous solid construction and demolition waste from industrial, commercial, institutional, and municipal sectors, including excess soil that cannot be beneficially reused (excluding any putrescible waste), from the Town of Dresden, within the Municipality of Chatham-Kent.

The application for amendment to the landfill is to allow a maximum fill rate of 1,000 tonnes per day, or 365,000 tonnes annually. At this fill rate, the 8-hectare landfill would reach capacity in 2032, assuming construction of the engineered landfill was completed in 2024.

The application for amendment seeks to incorporate the maximum theoretical capacity of the 8-hectare landfill area being 1,620,000 cubic metres. The theoretical capacity includes an estimated 40,000 cubic metres of previously landfilled material (predominantly fly ash from an incinerator) existing in non-engineered cells. The application for amendment also includes environmental improvements to the existing landfill, including converting the non-engineered landfill into an engineered landfill meeting current environmental standards, and consolidating the existing buried wastes into an engineered landfill cell located in the northeast corner of the property.

The application for amendment is also to allow operations at the landfill 24 hours per day, 7 days per week, 365 days per year.

The application for amendment to the landfill also includes the following construction details updating the landfill to current environmental standards:

• installation of several monitoring wells to detect potential impacts (if any) from the engineered landfill,
• construction of an engineered landfill with a compacted clay liner, a geomembrane liner, and a leachate collection and extraction system including a leachate pond
  • the site is currently underlain by several metres of competent clay, however the current environmental standards call for 750 millimetres of re-compacted clay liner;
  • above the re-compacted clay liner is a geomembrane liner and leachate collection system at elevation 179 metres above sea level (masl), or 2.5 metres (8 feet) below existing grade, and;
  • the maximum elevation of the landfill is 226 masl, or 35 metres (80 feet) above existing grade.
• construction of a stormwater management system including a stormwater management pond and stormwater collection and conveyance ditches, and;
• construction of screening berms along the south, west and north property boundaries.
