Need / Rationale For the Undertaking

 Secure and viable source of clayey material (liner) and aggregate (rock) until end of projected landfill life;  Nine landfill cells scheduled to be built between 2020 and 2048;  Reduction of sourcing uncertainty;  Reduction in construction costs; and  Advantages of a clay liner.

Engineering Assessments

 Potential clay source on this property was known historically;  In Summer 2018, the potential clay source was assessed for:

• Quality (properties such as hydraulic conductivity, % clay, % moisture, plasticity, etc.);
• All lab tests show the material meets or exceeds required properties;
• Quantity - sufficient amount to complete all liners for the projected landfill life;

 Bedrock on the site was also assessed (quality and quantity);

• Bedrock can be processed and used for many materials in landfill construction:
• i.e., gas venting layer, berm material, sub-base, road materials, etc.; and
• Readily available on the site via existing access road and quarry faces.

Environmental Impact Assessment (EIA) Overview

Regulatory Requirements

The proposed project is specified as an undertaking outlined in Schedule A of the New Brunswick Environmental Impact Assessment Regulation 87-83 under paragraph: (v): all enterprises, activities, projects, structure, works or programs affecting two hectares of more of bog, marsh, swamp or other wetland.

Environmental Impact Assessment (EIA) Overview

EIA Methodology

• 1. Valued Environmental Components (VEC);
• 2. Boundaries + Methodology;
• 3. Existing Environment;
• 4. Potential Project Effects;
• 5. Mitigation Measures; and
• 6. Significant Residual Effects.

EIA – Valued Environmental Components (VEC)

 Atmospheric Environment;  Groundwater;  Aquatic Environment;  Wildlife and Wildlife Habitat;  Wetlands and Vegetation;  Archeological and Heritage Areas;  Land Use; and  Effects of the Environment on the Project.
