BC Ministry of the Environment: Stage 11 Webinar Recordings and Presentations Posted

FEBRUARY 8, 2018 – The PowerPoint presentations and audio recordings for the webinars hosted in November and December 2017 are now available on the ministry’s Presentations website.  These webinars were to help stakeholders understand the changes to the recently approved Stage 11 amendments to the Contaminated Sites Regulation.

The webinars covered the following topics:

• Webinar 1 – Stage 10 (Omnibus) and Stage 11 (Housekeeping) Amendments
• Webinar 2 – Provincial and Regional Background Concentrations in Soil and Summary of Risk Assessment Updates
• Webinar 3 – Updates to Provincial Vapour Standards and Policy
• Webinar 4 – OMRR amendments and Stage 11 CSRA process
• Webinar 5 – Protocol 27, Soil Leachate Tests for Use in Deriving Site-Specific Numerical Soil Standards.  Protocol 2, Site-Specific Numerical Soil Standards
• Webinar 6 – Screening Level Risk assessment (SLRA) Update

The following 2 documents have been updated:

• Technical Guidance 24 – Site Specific Numerical Soil Standards Model Parameters
• Protocol 2 – Site Specific Numerical Soil Standards

The changes in these documents provide clarity to questions received from stakeholders:

• Site-specific soil standards (SSSs) can only be derived on sites where groundwater has been or will be investigated
• For pH sensitive substances, site-specific values for pH in soil are required when deriving SSSs for inorganics
• The vertical distance between the base of the source and the water table cannot exceed 10 m
