its by which they must be complied with, and the procedure for monitoring discharges 1.The limit valüs and the time limits for the industrial sectors concerned are set out together in the table below: >PLATZ FÜR EINE TABELLE> 00 2.Limit valüs expressed as concentrations which in principle must not be exceeded are given in the above table for the industrial sectors 2, 3, 4, 5 and 6. In no instance may limit valüs expressed as maximum concentrations be greater than those expressed as maximum quantities divided by water requirements per kilogram of cadmium handled. However, because the concentration of cadmium in effluents depends on the volume of water involved, which differs for different processes and plants, the limit valüs, expressed in terms of the quantity of cadmium discharged in relation to the quantity of mercury handled, given in the above table, must be complied with in all cases. 3.The daily average limit valüs are twice the corresponding monthly average limit valüs given in the above 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 valüs 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 the quantity of cadmium handled. Should the quantity of cadmium handled be impossible to determine, the monitoring procedure may be based on the quantity of cadmium 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 shall be taken. The quantity of cadmium discharged over a month must be calculated on the basis of the daily quantities of cadmium discharged. However, a simplified monitoring procedure may be instituted in the case of industrial plants which do not discharge more than 10 kilograms of cadmium per annum. In the case of industrial electroplating plants, a simpliefid monitoring procedure may only be instituted if the total volume of the electroplating tanks is leß than 1,5 m3. ANNEX II Quality objectives For those Contracting Parties applying quality objectives, emission standards shall be fixed so that the appropriate quality objective or objectives from among those listed below is or are complied with in the area affected by discharges of cadmium. The competent authority shall determine the area affected in each case and shall select from among the quality objectives listed in paragraph I below the objective or objectives that it deems appropriate, having regard to the intended use of the area affected, while taking account of the fact that the purpose of these programmes and measures is to prevent and eliminate all pollution. 1.The following quality objectives, which will be measured sufficiently close to the point discharge, are fixed(1), with the object of preventing and eliminating pollution within the meaning of Articles 1 and 4 of the Convention. 1.1The concentration of cadmium in solution in estuary waters up to the freshwater limit affected by discharges must not exceed 5 ìg/litre. 1.2The concentration of cadmium in solution must not exceed 2,5 ìg/litre in waters affected by discharges(2) as follows : (i)territorial waters; (ii)waters, other than estuary waters, on the landward side of the base line from which the breadth of the territorial sea is measured and extending in the case of watercourses up to the freshwater limit. 2.In addition to the above requirements, the results of the monitoring carried out in accordance with Article 2 must be compared with the following concentrations(1): 2.1In the case of estuary waters up to the freshwater limit, a concentration of cadmium in solution of 1 ìg/litre. 2.2A concentration of cadmium in solution of 0,5 ìg/litre in the case of water as follows: (i)territorial waters; (ii)waters, other than estuary waters, on the landward side of the base lines from which the breadth of the territorial sea is measured and extending in the case of watercourses up to the freshwater limit. 2.3If these concentrations are not complied with at any one of the points on the national network, the reasons must be reported to the Commission. 3.The concentration of cadmium in sediments and/or shellfish (mollusca and crustacea), if possible of the species Mytilus edulis, must not increase significantly with time. 4.Where several quality objectives are applied to waters in an area, the quality of the waters must be sufficient to comply with each of those objectives. ANNEX III Reference method of measurement 1.The reference method of analysis used for determining the cadmium content of waters, sediments and shellfish (mollusca and crustacea) is atomic absorption spectrophotometry after preservation and suitable treatment of the sample. The limits of detection must be such that the cadmium concentration can be measured to an accuracy of ± 30 % and a precision of ± 30 % at the following concentrations: -in the case of discharges, one-tenth of the maximum permitted concentration of cadmium specified in the authorization, -in the case of surface water, 0,1 ìg/litre or one-tenth of the cadmium concentration specified in the quality objective, whichever is the greater, -in the case of shellfish (mollusca and crustacea), 0,1 mg/kg wet weight, -in the case of sediments, one-tenth of the cadmium concentration in the sample or 0,1 mg/kg dry weight, with drying being carried out between 105 and 110 °C at constant weight, whichever valü is the greater. 2.Flow measurement must be carried out to an accuracy of ± 20 %. ANNEX IV Monitoring procedure for quality objectives 1.For each authorization the competent authority shall specify the restrictions, monitoring procedure and time limits for ensuring compliance with the quality objective(s) concerned. 2.The Contracting Parties shall, for each quality objective chosen and applied, report to the Commission: on: -the points of discharge and the means of dispersal, -the area in which the quality objective is applied, -the location of sampling points, -the frequency of sampling, -the methods of sampling and measurement, -the results obtained. 3.Samples must be sufficiently representative of the quality of the aquatic environment in the area affected by the discharges, and the frequency of sampling must be sufficient to show any changes in the aquatic environment, taking into account, in particular, natural variations in the hydrological regime. (1)A quality objective for the high seas is not fixed, on the understanding that the quality objective for territorial waters and other waters will protect the high seas from pollution. (1)All concentrations relate to the arithmetic mean of the results obtained over one year. (2)A quality objective for the high seas is not fixed on the understanding that the quality objective for territorial waters and other waters will protect the high seas from pollution.
