1,4 INSTRUMENTATION STRATEGY AND THE REGULATORV PROCESS
It is difficult to specify in regulations which geotechnical measurement
techniques should be used, or when, why, where and how they should be
used. The basic need is for quality information and not necessarily
the specialized information from a single instrument or data analysis
technique. As experience in the mining and petroleum fields shows, first
a decision must be made as to what type of information is required, and
then the decision is made as to how to obtain it. For the case of a waste
repository, the information required will be related to the regulatory
requirements of that repository. These requirements will be related to
the stability of the underground openings and the long-term waste con-
taining ability of storage areas. Requirements for specific information
can be included in the regulation, but flexibility should be given to the
repository operator as to how to obtain it.
Iwo measurement phases need to be detailed, however, because they are
critically important in the regulatory cycle. These are (1) geot chnical
exploration—to determine the characteristics of site—and (2) geotechnical
monitoring—to detect and identify possible adverse conditions (especially
conditions favoring waste leakage) within a repository.
A. Comments on Exploration Strategy
The basic problem of exploration is to define the geologic nature of a
site, including the types and physical properties of rock present, the
geometric configuration of those rocks, the location and orientation of
structural features such as faults, joints, folds, and fractured areas,
and the groundwater system. Exploration must be sufficiently detailed
to provide adequate information to assess the rock stability and contain-
ment capabilities of a site. This information may be obtained from
large- or small-scale investigations—i.e,, from feasibility explora-
tion of an entire repository site or from analysis of a particular
storage panel underground.
