For the application of 20° of article L. 3321-1, the constitution of provisions for risks and charges and for depreciation of assets is mandatory as soon as the risk arises.
The chairman of the departmental council must set aside the provision for the amount of the risk identified.
The provision must be adjusted annually in line with changes in the risk. It shall be written back when it has become redundant, i.e. when the risk materialises or when the risk is no longer likely to materialise.
The amount of the provision as well as its monitoring and use shall be recorded on the statement of provisions made attached to the budget and the administrative account.
