Regime III Declarations of Group III chemicals should encompass all the chemicals in chemical weapons stocks as under Regime I as well as stocks for permitted purposes and aggregate annual production of each of the Group III chemicals, stating also their respective end uses. Facilities for production of Group III chemicals should be declared as under Regime I if the production has been for chemical weapons purposes or exceeds certain quantities, stating the aggregate capacity for each compound as well as the locations of the facilities. Elimination . The elimination of the Group III chemicals in chemical weapon stocks could be carried out through destruction or diversion for permitted purposes. Elimination of facilities having produced these chemicals for chemical weapons purposes shall take place through destruction or dismantling if the total production capacity exceeds what is consistent with production for permitted purposes . Production . No limitations in amount or place of production is envisaged. Verification . The verification measures applicable under Regime III would comprise data-reporting on each individual chemical and systematic international on-site inspection.

**Analysis**
The text appears to be discussing the regulation and control of chemical weapons and the measures to eliminate them. It mentions different groups of chemicals, their production, and the verification measures to ensure compliance. The text seems to be focused on international cooperation and agreement, as it refers to "Regime I", "Regime II", and "Regime III", which suggests a framework for international law.
