Management plan

On February 8, 2007, the Ministry of the Environment issued new regulations on the prevention of soil pollution and the management of polluted soils in France. Within this framework, a ministerial memorandum specified the management and redevelopment procedures for polluted sites, and in particular the two main types of management situation to be implemented:

• the environmental interpretation approach (IEM): this ensures that the state of the environment is compatible with the uses already established, thereby highlighting the situations that allow free use of the environment and those that are likely to pose a problem. The IEM is presented in the article [G 2 562] by J.R. Mossmann;

• the management plan (MP): depending on the situation, this enables action to be taken both on the site's condition (through development or decontamination measures) and on the uses, which can be chosen or adapted; the management plan is applied when it is possible to act on the uses (uses are under control).

The Ministry's various texts are available on the website dedicated to polluted sites (see "Find out more", under "Websites"). Appendix 2 of this note, entitled "How to identify a (potentially) polluted site/How to manage a polluted site problem/Methods for managing and redeveloping polluted sites", gives a detailed presentation of the management plan. .

This article deals with the various aspects to be considered in the context of a management plan, namely: analysis of the issues at stake, control of pollution sources, control of impacts, definition of the various management scenarios, cost/benefit balance, performance of remediation techniques, construction measures, management of cut/fill, analysis of residual risks, restrictions...
