   (a)  effective means of controlling and operating all relevant emergency
        shut-down valves for a pipeline; and

   (b)  a fail-safe system of isolating a pipeline in the event of failure of
        other safety devices for the pipeline.

(3) The Safety Case in respect of a facility must also specify:

   (a)  adequate means of mitigating, in the event of emergency, the risks
        associated with each pipeline connected to the facility; and

   (b)  a frequency of periodic inspection and testing of pipeline emergency
        shut-down valves that can reasonably be expected to ensure that they
        will operate correctly in an emergency.
