The Facility Agreement between the Czech Republic and the Organisation for the Prohibition of Chemical Weapons Regarding On-Site Inspections at a Schedule 1 Protective Purposes Facility, signed in The Hague on 15 June 2011, entered into force on 13 February 2012. This agreement provides for arrangements governing the on-site inspections conducted by OPCW inspection teams at the protective purposes facility producing established maximum quantities of Schedule 1 chemicals. The Agreement is part of the legal framework enabling the Czech facility to produce Schedule 1 chemicals in aggregate quantities not exceeding 10 kg per year, in accordance with the relevant provisions of the Chemical Weapons Convention. This amount is sufficient to cover the needs of the training and research activities in the field of protection against chemical weapons in which the Czech Army has special expertise.
