The presidents of the regional councils concerned sign the agreement between the regions, in the light of the concordant deliberations of the regional councils and, where applicable, the acceptances given under the conditions provided for in Article R. 5611-2.
This specifies in particular, in addition to the purpose and duration for which it is concluded, the foreseeable cost of the operations envisaged and the distribution of expenses.
The agreement designates the local authority or public establishment on whose behalf the work is carried out in application of article L. 4211-1 as well as, where applicable, that of the regions responsible for carrying it out.
Each president of the regional council is responsible for ensuring that the agreement is implemented, insofar as he or she is concerned.
