i) Phase I: not later than two years after entry into force of this Convention, testing of its first destruction facility shall be completed. Not less than 1% of the category 1 chemical weapons shall be destroyed not later than three years after the entry into force of this Convention;

it) Phase 2: not less than 20% of the category 1 chemical weapons shall be destroyed not later than five years after the entry into force of this Convention;

Hi) Phase 3: not less than 45% of the category 1 chemical weapons shall be destroyed not later than seven years after the entry into force of this Convention;

iv) Phase 4: all category 1 chemical weapons shall be destroyed not later than 10 years after the entry into force of this Convention;

b) The destruction of category 2 chemical weapons not later than one year after this Convention enters into force for it and shall complete the destruction not later than five years after the entry into force of this Convention. Category 2 chemical weapons shall be destroyed in equal annual increments throughout the destruction period. The comparison factor for such weapons is the weight of the chemicals within category 2; and

c) The destruction of category 3 chemical weapons not later than one year after this Convention enters into force for it, and shall complete the destruction not later than five years after the entry into force of this Convention. Category 3 chemical weapons shall be destroyed in equal annual increments throughout the destruction period. The comparison factor for unfilled munitions and devices is expressed in nominal fill volume (m3) and for equipment in number of items.

18 — For the destruction of binary chemical weapons the following shall apply.

• a) For the purposes of the order of destruction, a declared quantity (in tonnes) of the key component intended for a specific toxic end-product shall be considered equivalent to the quantity (in tonnes) of this toxic end-product calculated on a stoichiometric basis assuming 100 % yield;

b) A requirement to destroy a given quantity of the key component shall entail a requirement to destroy a corresponding quantity of the other component, calculated from the actual weight ratio of the components in the relevant type of binary chemical munition/device;

c) If more of the other component is declared than is needed, based on the actual weight ratio between components, the excess shall be destroyed over the first two years after destruction operations begin;

d) At the end of each subsequent operational year a State Party may retain an amount of the other declared component that is determined on the basis of the actual weight rauo of the components in the relevant type of binary chemical munition/device.

19 — For multicomponent chemical weapons the order of destruction shall be analogous to that envisaged for binary chemical weapons.'

Modification of intermediate destruction deadlines

20 — The Executive Council shall review the general plans for destruction of chemical weapons, submitted pursuant to article in, paragraph 1, a), v), and in accordance with paragraph 6, inter alia, to assess their conformity with the order of destruction set forth in paragraphs 15 to 19. The Executive Council shall consult with any State Party whose plan does not conform, with the objective of bringing the plan into conformity.

21 —If a State Party, due to exceptional circumstances beyond its control, believes that it cannot achieve the level of destruction specified for phase 1, phase 2 or phase 3 of the order of destruction of category 1 chemical weapons, it may propose changes in those levels. Such a proposal must be made not later than 120 days after the entry into force of this Convention and shall contain a detailed explanation of the reasons for the proposal.

22 —■ Each State Party shall take all necessary measures to ensure destruction of category 1 chemical weapons in accordance with the destruction deadlines set forth in paragraph 17, a), as changed pursuant to paragraph 21. However, if a State Party believes that it will be unable to ensure the destruction of the percentage of category 1 chemical weapons required by an intermediate destruction deadline, it may request the Executive Council to recommend to the Conference to grant ah extension of its obligation to meet that deadline. Such a request must be made not less than 180 days, before the intermediate destruction deadline and shall contain a detailed explanation of the reasons for the request and the plans of the State Party for ensuring that it will be able to fulfil its obligation to meet the next intermediate destruction deadline.

23 — If an extension is granted, the State Party shall still be under the obligation to meet the cumulative destruction requirements set forth for the next destruction deadline. Extensions granted pursuant to this section shall not, in any way, modify the obligation of the State Party to destroy all category 1 chemical weapons not later than 10 years after the entry into force of this Convention.

Extension of the deadline for completion of destruction

24 — If a State Party believes that it will be unable to ensure the destruction of all category 1 chemical weapons not later than 10 years after the entry into force of this Convention, it may submit a request to the Executive Council for an extension of the deadline for completing the destruction of such chemical weapons. Such a request must be made not later than nine years after the entry into force of this Convention.

25 — The request shall contain:

a) The duration of the proposed extension;

b) A detailed explanation of the reasons for the proposed extension; and

c) A detailed plan for destruction-during the proposed extension and the remaining portion of the original 10-year period for destruction.
