Division 3.3.1 Hazard characterisation

Hazard characterisation shall be undertaken by characterising the potential for leakage from the storage complex, as established through dynamic modelling and security characterisation described above. This shall include consideration of, inter alia:

1. (a)

   potential leakage pathways;

2. (b)

   potential magnitude of leakage events for identified leakage pathways (flux rates);

3. (c)

   critical parameters affecting potential leakage (for example maximum reservoir pressure, maximum injection rate, temperature, sensitivity to various assumptions in the static geological Earth model(s));

4. (d)

   secondary effects of storage of CO₂, including displaced formation fluids and new substances created by the storing of CO₂;

5. (e)

   any other factors which could pose a hazard to human health or the environment (for example physical structures associated with the project).

The hazard characterisation shall cover the full range of potential operating conditions to test the security of the storage complex.
