1.13. This Safety Guide emphasizes the integration of monitoring and surveillance activities necessary for development of and compliance with the safety case. The safety case includes information related to siting, construction, operation, closure and the period after closure that is necessary for supporting decisions on managing the disposal programme, as well as information that is of particular interest to interested parties such as local parties and the wider public [2, 13]. Technical details on monitoring and surveillance methodologies are beyond the scope of this Safety Guide; however, Refs [8?11] contain such information, and Annexes I and II provide examples of monitoring programmes for geological disposal programmes and for near surface disposal programmes.
