The Director-General shall promptly submit a report to the Executive Council, the Conference, and all States Parties containing his recommendations on the measures necessary to convert the facility to purposes not prohibited under this Convention and to provide assurance that the converted facility will be used only for purposes not prohibited under this Convention.
74. If the facility has been used for purposes not prohibited under this Convention before this Convention enters into force for the State Party, and is continuing to be in operation, but the measures required to be certified under paragraph 68 have not been taken, the Director-General shall immediately inform the Executive Council, which may require implementation of measures it deems appropriate, inter alia, shut-down of the facility and removal of specialized equipment and modification of buildings or structures. The Executive Council shall stipulate the deadline for implementation of these measures and shall suspend consideration of the request pending their satisfactory completion. The facility shall be inspected promptly after the expiration of the deadline to determine whether the measures have been implemented. If not, the State Party shall be required to shut down completely all facility operations.
75. As soon as possible after receiving the report of the Director-General, the Conference, upon recommendation of the Executive Council, shall decide, taking into account the report and any views expressed by States Parties, whether to approve the request, and shall establish the conditions upon which approval is contingent. If any State Party objects to approval of the request and the associated conditions, consultations shall be undertaken among interested States Parties for up to 90 days to seek a mutually acceptable solution. A decision on the request and associated conditions, along with any proposed modifications thereto, shall be taken, as a matter of substance, as soon as possible after the end of the consultation period.
76. If the request is approved, a facility agreement shall be completed not later than 90 days after such a decision is taken. The facility agreement shall contain the conditions under which the conversion and use of the facility is permitted, including measures for verification. Conversion shall not begin before the facility agreement is concluded.

Detailed plans for conversion

77. Not less than 180 days before conversion of a chemical weapons production facility is planned to begin, the State Party shall provide the Technical Secretariat with the detailed plans for conversion of the facility, including proposed measures for verification of conversion, with respect to, inter alia:
    1. Timing of the presence of the inspectors at the facility to be converted; and
    2. Procedures for verification of measures to be applied to each item on the declared inventory.
78. The detailed plan for conversion of each chemical weapons production facility shall contain:
    1. Detailed time schedule of the conversion process;
    2. Layout of the facility before and after conversion;
    3. Process flow diagram of the facility before, and as appropriate, after the conversion;
    4. Detailed inventory of equipment, buildings and structures and other items to be destroyed and of the buildings and structures to be modified;
    5. Measures to be applied to each item on the inventory, if any;
    6. Proposed measures for verification;
    7. Security/safety measures to be observed during the conversion of the facility; and
    8. Working and living conditions to be provided for inspectors.

Review of detailed plans

79. On the basis of the detailed plan for conversion and proposed measures for verification submitted by the State Party, and on experience from previous inspections, the Technical Secretariat shall prepare a plan for verifying the conversion of the facility, consulting closely with the State Party. Any differences between the Technical Secretariat and the State Party concerning appropriate measures shall be resolved through consultations. Any unresolved matters shall be forwarded to the Executive Council for appropriate action with a view to facilitate the full implementation of this Convention.
80. To ensure that the provisions of Article V and this Part are fulfilled, the combined plans for conversion and verification shall be agreed upon between the Executive Council and the State Party. This agreement shall be completed not less than 60 days before conversion is planned to begin.
81. Each member of the Executive Council may consult with the Technical Secretariat on any issue regarding the adequacy of the combined plan for conversion and verification. If there are no objections by any member of the Executive Council, the plan shall be put into action.
82. If there are any difficulties, the Executive Council should enter into consultations with the State Party to reconcile them. If any difficulties remain unresolved, they should be referred to the Conference. The resolution of any differences over methods of conversion should not delay the execution of other parts of the conversion plan that are acceptable.
83. If agreement is not reached with the Executive Council on aspects of verification, or if the approved verification plan cannot be put into action, verification of conversion shall proceed through continuous monitoring with on-site instruments and physical presence of inspectors.
84. Conversion and verification shall proceed according to the agreed plan. The verification shall not unduly interfere with the conversion process and shall be conducted through the presence of inspectors to confirm the conversion.
85. For the 10 years after the Director-General certifies that conversion is complete, the State Party shall provide to inspectors unimpeded access to the facility at any time. The inspectors shall have the right to observe all areas, all activities, and all items of equipment at the facility. The inspectors shall have the right to verify that the activities at the facility are consistent with any conditions established under this Section, by the Executive Council and the Conference. The inspectors shall also have the right, in accordance with provisions of Part II, Section E, of this Annex to receive samples from any area of the facility and to analyse them to verify the absence of Schedule 1 chemicals, their stable by-products and decomposition products and of Schedule 2 chemicals and to verify that the activities at the facility are consistent with any other conditions on chemical activities established under this Section, by the Executive Council and the Conference. The inspectors shall also have the right to managed access, in accordance with Part X, Section C, of this Annex, to the plant site at which the facility is located. During the 10-year period, the State Party shall report annually on the activities at the converted facility. Upon completion of the 10-year period, the Executive Council, taking into account recommendations of the Technical Secretariat, shall decide on the nature of continued verification measures.
86. Costs of verification of the converted facility shall be allocated in accordance with Article V, paragraph 19.
