General duty
13.—(1) The well-operator shall ensure that a well is so designed, modified, commissioned, constructed, equipped, operated, maintained, suspended and abandoned that—
(a)so far as is reasonably practicable, there can be no unplanned escape of fluids from the well; and
(b)risks to the health and safety of persons from it or anything in it, or in strata to which it is connected, are as low as is reasonably practicable.
(2) The provisions of regulations 14 to 19 and 21 are without prejudice to the generality of the requirements of paragraph (1) save that, where regulation 17(2) places a duty on the duty holder for an installation, the well-operator is not under the same duty.
