Comment
In section 5.4.1 reference is made to multiple gas probes being installed in a single borehole. Clause 12 (a) vi of Table 4 of Schedule E of O.Reg 153/04 prohibits the installation of multiple probes in a single borehole, for MGRAs. The guidance manual should be revised to indicate that for MGRAs multiple gas probes in a single borehole are not permitted under the Regulation.
