APEGBC on Bill Bennett's resignation ....... Mary soon to follow




APEGBC is reviewing the report in detail to determine what impacts it may have on members and the practice of engineering and geoscience in BC.  As a regulator, APEGBC’s primary interest is in seeking to minimise risk to public safety.

APEGBC currently has an investigation underway on the role of engineering professionals involved in the Mount Polley Mining Dam collapse.

Following up on the recommendations of the Independent Engineering Expert Panel Report on Mount Polley, APEGBC is continuing to provide input on the Ministry of Energy and Mines’s development of new codes for the mining industry and is working to clarify the role and responsibilities of Professionals of Record within this sector. APEGBC Council also recently approved the APEGBC Professional Practice Guidelines: Site Characterisation for Dam Foundations in British Columbia at their April meeting, with publication targeted for summer 2016.




Site Characterisation for Dam Foundations in British Columbia
Pleistocene valley fills containing glaciolacustrine and other fine-grained sediments commonly occur in many British Columbia valleys. Many of these deposits contain multiple glaciolacustrine units separated by glacial tills and outwash gravels, sometimes displaying complex stratigraphy. Processes active during and following deglaciation often shows evidence of glacial induced deformation and shearing. Many mine tailings and waste rock embankments in British Columbia are situated on these complex glacial foundations. It is imperative that site investigation methods adequately characterize the distribution and key geotechnical conditions governing stability and deformation of tailings dams and other containment structures situated on weak valley sediments.
