The Oil and Pipelines Agency (OPA), as the operator of the Redcliffe Bay fuel storage depot has the duty under the Control of Major Accident Hazards Regulations (COMAH), to conduct and complete a risk assessment for the site.
The COMAH Regulations are enforced in England and Wales by a competent authority comprising of the Health and Safety Executive (HSE) and the Environmental Agency (EA).
OPA has produced a safety report which included the main results and arguments of the hazard analysis and risk analysis, and submitted this to the competent authority for assessment as required by COMAH. In the safety report, OPA was required to demonstrate that it has taken all measures necessary to prevent major accidents and to limit the consequences to people and the environment of any that might occur. The HSE has completed its part of the competent authority's assessment of the Redcliffe Bay Safety report, and this has been included in the competent authority's conclusions on its overall determination of the case for safety made by OPA in the report.
