(1) A person must not,
without the written authority of the electricity infrastructure
operator—
(a) cut
away, excavate or remove, or cause to be cut away, excavated or removed, earth
or material supporting electricity infrastructure so as to endanger the
stability of the infrastructure; or
(b) make
an excavation deeper than 0.3 metre within 3 metres of—
(i)
a pole structure or stand, not being a tower or tower
structure supporting electricity infrastructure; or
(ii)
any pole or bed log to which is affixed a staywire used
to support electricity infrastructure; or
(c) make
an excavation deeper than 0.5 metre within 10 metres of any tower or
tower structure supporting electricity infrastructure; or
(d) make
an excavation deeper than 0.3 metre within 0.6 metre of any wall,
fence or foundation of a substation; or
(e)
place any material, construct any artificial surface above ground level,
smooth the ground or remove vegetation—
(i)
below an electric line or within the vertical projection
of any points to which a conductor of the electric line may sway; or

in a manner that may—
(iii)
in any case—alter the level of the ground at any
place so as to infringe any permissible clearance distance under these
regulations; or
(iv)
in the case of smoothing of ground or removal of
vegetation—allow the ground to be used in a manner that was not possible
before the smoothing or removal.
(2) The allowable
depth of an excavation under subregulation (1) is, if the ground level
unaffected by previous works is known, to be determined by reference to that
level, but is otherwise to be determined by reference to the current ground
level.
