6. Setting Standards

7. What is a Contaminated Site? 2. (1) For the purposes of section 111 of the Act, a site is a contaminated site if (a) the land use is agricultural, commercial, industrial, park or residential, and the concentration of any contaminant in the soil at the site is greater than or equal to (i) the generic numerical soil standards in Schedule 1, or (ii) the matrix numerical soil standards in Schedule 2; or (b) the surface water or groundwater which (i) is located on the site, or (ii) flows from the site is used or has a reasonable probability of being used for aquatic life, irrigation, livestock or drinking water, and the concentration of any contaminant in the surface water orgroundwater is greater than or equal to the concentrationof that contaminant specified for that use in Schedule 3

8. Setting Standards • Soil • Agricultural • Park • Residential • Commercial • Industrial • Groundwater • Aquatic Life (fresh water and marine) • Irrigation • Livestock • Drinking Water

9. Risk Assessment

10. Site Assessment Process Site Investigation (Phase I Assessment) Site Assessment (Phase II Assessment) Plan of Restoration developed to set out how contamination will be cleaned up

11. Selecting Restoration Standards • Numerical Standards • Generic Numerical Soil Standards • Matrix Numerical Soil Standards • Generic Numerical Water Standards • Background Concentrations • Risk Assessment Based Standards

12. Remediation Ex-situ – removal of contaminants from the site for treatment and/or disposal In-situ – treating contaminants without removing it from the environment Risk Management – reducing the risk to human health and the environment without removing the contaminants

13. Permits Relocation Permit – required to move material from one site to another Land Treatment Facility Permit – required to construct or operate to treat contaminated material Risk-based restoration permit – required to implement site-specific cleanup standards developed through a risk assessment process
