DECISION

PROCEDURES FOR THE CLOSURE/INACTIVATION OF CWPF

The Conference

Recalling that the Commission, in its PC-V/12, subparagraph 6.2(a), adopted the understanding that the set of procedures identified as being necessary for the closure/inactivation of CWPFs in the context of their subsequent destruction or, pending a final decision, their temporary conversion to chemical weapons destruction facilities or possible conversion for purposes not prohibited by the Convention, should apply in all of the above three cases,

Bearing in mind that the Commission recommended in paragraph 49.3.5 of its Final Report that the Conference adopt the above mentioned procedures and understanding,

Hereby:

1. Adopts the procedures necessary for the closure/inactivation of CWPFs in the context of their subsequent destruction or, pending a final decision, their temporary conversion to chemical weapons destruction facilities or possible conversion for purposes not prohibited by the Convention, annexed hereto, as well as the understanding that the above mentioned procedures should apply in all of the three cases.
