ANNEX I

Limit values, time limits by which they must be complied with, and the procedure for monitoring discharges 1. The limit values and the time limits for the industrial sectors concerned are set out together in the table below: 1.2,3.4 // // // // // Limit value which must be complied with as from: // // 1.2.3.4 // Industrial sector (1) // 1 July 1986 // 1 July 1989 // Unit of measurement // // // // // 1. Chemical industries using mercury catalysts: // // // // (a) in the production of vinyl chloride // 0,1 // 0,05 // mg/l effluent // // 0,2 // 0,1 // g/t vinyl chloride production capacity // (b) in other processes // 0,1 // 0,05 // mg/l effluent // // 10 // 5 // g/kg mercury processed // // // // // 2. Manufacture of mercury catalysts used in the production of vinyl chloride // 0,1 1,4 // 0,05 0,7 // mg/l effluent g/kg mercury processed // // // // // 3. Manufacture of organic and non-organic mercury compounds (except for products referred to in point 2) // 0,1 0,1 // 0,05 0,05 // mg/l effluent g/kg mercury processed // // // // // 4. Manufacture of primary batteries containing mercury // 0,1 0,05 // 0,05 0,03 // mg/l effluent g/kg mercury processed // // // // // 5. Non-ferrous metal industry (2) // // // // 5.1. Mercury recovery plants // 0,1 // 0,05 // mg/l effluent // 5.2. Extraction and refining of non-ferrous metals // 0,1 // 0,05 // mg/l effluent // // // // // 6. Plants for the treatment of toxic wastes containing mercury // 0,1 // 0,05 // mg/l effluent // // // // The limit values given in the table correspond to a monthly average concentration or to a maximum monthly load. The amounts of mercury discharged are expressed as a function of the amount of mercury used or handled by the industrial plant over the same period or as a function of the installed vinyl chloride production capacity. 2. Limit values expressed as concentrations which in principle must not be exceeded are given in the above table for the industrial sectors 1 to 4. In no instance may limit values expressed as maximum concentrations be greater than those expressed as maximum quantities divided by water requirements per kilogram of mercury handled or per tonne of installed vinyl chloride production capacity. However, because the concentration of mercury in effluents depends on the volume of water involved, which differs for different processes and plants, the limit values, expressed in terms of the quantity of mercury discharged in relation to the quantity of mercury handled or to the installed vinyl chloride production capacity, given in the above table, must be complied with in all cases. 3. The daily average limit values are twice the corresponding monthly average limit values given in the table. 4. A monitoring procedure must be instituted to check whether the discharges comply with the emission standards which have been fixed in accordance with the limit values laid down in this Annex. This procedure must provide for the taking and analysis of samples and for measurement of the flow of the discharge and, where appropriate, the quantity of mercury handled. Should the quantity of mercury handled be impossible to determine, the monitoring procedure may be based on the quantity of mercury that may be used in the light of the production capacity on which the authorization was based. 5. A sample representative of the discharge over a period of 24 hours will be taken. The quantity of mercury discharged over a month must be calculated on the basis of the daily quantities of mercury discharged. However, a simplified monitoring procedure may be instituted in the case of industrial plants which do not discharge more than 7,5 kilograms of mercury per annum.
