The workshop attracted wide participation from relevant Russian and western organizations. International expertise from several related fields went together to produce a thorough understanding of the present status and how to develop the use of overall risk assessments and environmental impact assessments to ensure a sound use of resources when carrying out the tremendous work that must be carried out to clean up the cold war legacy. Important conclusions and recommendations have been produced and set out in the main report, providing a good basis for further development. Such development should note that safety and environmental performance can be addressed at three levels: Compliance-focused; Beyond compliance, towards best practice; and Continuous improvement. The aim is to progress from a) to b) and eventually reach c). The levels refer both to operators performance and regulators and other stakeholders expectations.
