Response to
Information Requests
Provides clarification on the
environment of deposition and
genetic aspects of the subsurface
deposits found on the DGR site
Provides additional information on
locations of Waste Rock
Management Area, shafts boreholes
and monitoring wells
Provides justification for the
sufficiency of hydrogeologic
modelling with respect to assessing
the influence of a laterally continuous
permeable unit at the base of the
sedimentary sequence
Provides clarification regarding: 1)
the confidence in the longevity of the
abnormal pressures observed at the
site, and 2) conservatism applied in
the hydrogeologic and safety
assessment modelling scenarios with
regard to abnormal pressure
evolution
Provides clarification as to how the
hydraulic parameters used to
represent the shale formations in the
hydrogeologic modelling were
derived
Provides justification for the
hydrogeologic modelling
discretization with respect to the
Guelph and Salina A1 Unit aquifers
