Alberta Environment issues new contaminated site remediation guidelines
New guidelines from Alberta Environment for the remediation of contaminated sites are now in effect, with certain exceptions. Both Tier 1 and Tier 2 Soil and Groundwater Remediation Guidelines provide information on managing contaminated sites and set out common objectives for assessing and cleaning up all such sites.
The Tier 1 guidelines consolidate the most current guidelines from a number of sources (including the Canadian Council of Ministers of the Environment, Health Canada and Alberta Environment) into a single reference document. Building on this basic information, the Tier 2 guidelines describe how the Tier 1 guidelines can be modified using site-specific information.
Both documents replace the Alberta Soil and Water Quality Guidelines for Hydrocarbons at Upstream Oil and Gas Facilities (2001 Upstream Guidelines). However, Alberta Environment will continue to accept applications that comply with the 2001 Upstream Guidelines provided the laboratory analytical data report(s) from a Phase 2 environmental site assessment or confirmatory sampling event is dated on or before December 1, 2007.
Soil monitoring and management programs at approved facilities will transition to the new Tier 1 or Tier 2 Guidelines as required by the facility operating approval and the Soil Alberta Environment has also released for public review a draft Tier 2 Eco-contact Guideline Derivation Protocol. This document provides a protocol for developing site-specific eco-contact guidelines for petroleum hydrocarbons.
Comments on this protocol are due by September 28, 2007 and should be sent to Gordon Dinwoodie, Environmental Policy Branch, Alberta Environment, 10th Floor, 9820 - 106 Street, Edmonton T5K 2J6.
The guidelines and draft protocol may be viewed on-line at www3.gov.ab.ca/env/protenf/landrec/gw_remediation_guidelines.html.
