Alberta Environment has consolidated soils and groundwater remediation guidelines from a number of sources (Canadian Council of Ministers of the Environment, Health Canada, and Alberta Environment) into a single, comprehensive, Tier 1 guidance document. A companion Tier 2 guidance document has also been developed that details how Tier 1 guidelines can be modified based on site-specific information. Both guidelines maintain an equivalent level of ecological and human health protection. This workshop is intended to provide a general technical overview of the new Tier 1 and Tier 2 guidance documents, highlighting key regulatory requirements needed for site closure. AENV will be present at the workshops to discuss the regulatory requirements.
