Article 5
1. The Contracting Parties shall implement these programmes and measures by 1 January 1986. 2. Contracting Parties shall communicate to the Commission the text of the provisions of internal law which they adopt in the field governed by these programmes and measures. N° L 375/ 30. 12. 85 00 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: >TABLE> 00 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 shall 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. N°tes 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. 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 mercury. The competent authority shall determine the area affected in each case and shall select from among the quality objectives listed in paragraph 1 below the objective or objectives that it deems appropriate, having regard to the intended use of the area affected, taking account of the fact that the purpose of these programmes and measures is to prevent and eliminate all pollution. 1.In order to prevent and eliminate pollution as defined in Article 1 of the Convention and pursuant to Article 4 of the said Convention, the following quality objectives are set: 1.1The concentration of mercury in a representative sample of fish flesh chosen as an indicator must not exceed 0,3 mg/kg wet fish. 1.2The concentration of mercury in solution in estuary waters up to the freshwater limit affected by discharges must not exceed 0,5 ìg/l as the arithmetic mean of the results obtained over a year. 1.3The concentration of mercury in solution in the following waters(1) must not exceed 0,3 ìg/l as the arithmetic mean of the results obtained over a year: (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.The concentration of mercury in sediments or in shellfish (mollusca and crustacea) must not increase significantly with time. 3.Where several quality objectives are applied to waters in an area, the quality of the waters must be sufficient to meet each of them. 4.The numerical values of the quality objectives specified in paragraphs (2) and 1 (3) may, as an exception and where this is necessary for technical reasons, be multiplied by 1,5 until 1 July 1989. ANNEX III Reference method of measurement 1.The reference method of analysis used for determining the mercury content of waters, the flesh of fish, sediments and shellfish (mollusca and crustacea) is flameless atomic absorption spectrophotometry after suitbable pre-treatment of the sample which takes account in particular of pre-oxidation of the mercury and of successive reduction of the mercury ions Hg(II). The limits of detection must be such that the mercury 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 mercury specified in the authorization, -in the case of surface water, one-tenth of the mercury concentration specified in the quality objective, -in the case of the flesh of fish and shellfish (mollusca and crustacea), one-tenth of the mercury concentration specified in the quality objective, -in the case of sediments, one tenth of the mercury concentration in the sample or 0,05 mg/kg dry weight whichever value 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 or objectives 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 of measurement, -the results obtained. 3.Samples must be properly 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. The salt-water fish analysis must be carried out on a sufficiently representative number of samples and species. 4.With regard to the quality objective in paragraph 1.1 of Annex II, the competent authority shall choose the species of fish to be adopted as indicators for analysis. For salt waters the species chosen from among those inhabiting coastal waters and caught locally may include cod (Gadus morhua), whiting (Merlangius merlangus), plaice (Pleuronectes platessa), mackerel (Scomber scombrus), haddock (Melanogrammus aeglefinus) and flounder (Platichthys flesus).
