Environmental Impact Assessment (EIA) Crane Mountain Landfill Clay - PowerPoint PPT Presentation

Environmental Impact Assessment (EIA) Crane Mountain Landfill Clay and Aggregate Quarry Saint John, New Brunswick

EIA – Crane Mountain Clay and Aggregate Quarry  Rationale / Need for the Undertaking;  Engineering Assessment;  Environmental Impact Assessment (EIA) Overview;  EIA – Valued Environmental Components;  Timeline + Next Steps; and  Questions.

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 LANDFILL built between 2020 and 2048;  Reduction of sourcing uncertainty;  Reduction in construction costs; and  Advantages of a clay liner.

Site Location Plan

Engineering Assessments  Potential clay source on this property was known historically;  In Summer 2018, the potential clay source was assessed for: o Quality (properties such as hydraulic conductivity, % clay, % moisture, plasticity, etc .); o All lab tests show the material meets or exceeds required properties; o Quantity - sufficient amount to complete all liners for the projected landfill life;  Bedrock on the site was also assessed (quality and quantity); o 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 o 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.
