9.3. The monitoring and surveillance programme for a waste disposal facility should be capable of providing data in support of decisions that will be made over the entire lifetime of the facility. Since the lifetime of a disposal facility is very long, it follows that the management system established should be such as to maintain continuity of data collection, continuity of data management, and adaptability to new approaches for the collection and interpretation of data. Some types of monitoring and surveillance require consistent, long term funding to be useful, and the management system should establish approaches to ensure the necessary continuity of funding. For instance, many field experiments may require years before they produce credible and useful data. Such experiments can be important to establishing a credible safety case, but they might also be subject to transitory funding restrictions that can end the experiment too early, limiting its usefulness. The management system should additionally establish provisions to ensure proper planning for financial resources and qualified human resources when necessary.
