Figure 16.2 Societal Risk Acceptance Criteria.
16.2.4 Environmental Risk
AI1 incidents considered as initiating in the assessment of individual and societal risks during
the operational phase are considered to be initiating for the purposes of determining the
Environmental Risks.
Loss of containment incidents during operation of pipeline will have minor local
environmental effects.
The environmental consequences of loss of containment incidents are therefore classified as
being Category 1 (Table 16.1), i.e. the recovery period will be less than 1 year.
In addition any incidents having the potential to result in the release of corrosion inhibitors
during commissioning of the pipeline are considered to be initiating with respect to
Environmental Risks.
Acceptance of the environmental risks associated with the construction and operation is
normally based on the operator’s criteria which is established based on economical and
political considerations.
