               The limit value for the monthly overall concentration of aldrin, dieldrin and endrin (*)
              discharges in an outflow of 750 000 m:l of waste water per month shall be fixed as follows:
              — from 1 January 1982, 20 /^g/1 for a monthly load of 15 kg;
              — from 1 January 1986, 4 ug/1 for a monthly load of 3 kg.
              In order to verify that the limit values are being observed, measurements are to be taken at
              least once a day from samples which are statistically representative of the discharges.
              The monthly concentration is to be calculated by taking the arithmetical mean of the daily
              mean values or, if this is not possible, of the available values. No value measured must be
              more than five times as high as the mean monthly value.
              If the outflow is greater or less than 750 000 nv1 per month, the limit values for the con-
              centrations shall be adjusted by means of the following formula:
              L    = adjusted limit value expressed in /^g/1,
              1     - 20 /<g/l from 1 January 1982,
                       4 fxg/I from 1 January 1986,
              Q0 =     750 000 m 3 per month,
              Q   — current outflow expressed in m 8 per month.
              With regard to the prescribed values which shall apply from 1 January 1986, if a manu-
              facturer can prove at least nine months before the time limit expires, i.e. in the first instance
              before 1 April 1985, that the limit values referred to cannot be achieved by using the best
              technical means available, the Member State concerned may extend the above time limit
              with the prior agreement of the Commission.
          2. Existing plants for mothproofing    ivool and wool products
             The limit value for the monthly concentration of dieldrin in the discharges shall be fixed
              from 1 January 1986 by the following formula:
               L   = limit value expressed in ^g/l,
                1   = 60 /ig/1,
              Q 0 = 175 m 3 per kg of pure dieldrin employed,
              Q   — quantity of water expressed in m 3 per kg of pure dieldrin employed.

                   In order to verify that the limit values are observed, measurements are to be taken at least
                   once a week from samples which are statistically representative of the discharges.
                   The monthly concentration must be calculated by taking the mean of the daily mean values
                   or, if this is not possible, of the values available. No measured value must be more than five
                   times as high as the mean monthly values.
             3. New plant manufacturing               aldrin, dieldrin and/or endrin and using dieldrin to mothproof
                   wool and wool products
                   The concentration in the discharges of aldrin, dieldrin and endrin (') taken together shall be
                   zero from the dare when the plant starts operating.
                   For the purposes of this Directive 'zero concentration' means a concentration of aldrin,
                   dieldrin or endrin which cannot be detected by the analytical method described in Annex II
                  or by a similar method.
                   With the Commission's prior agreement, Member States may grant an exemption based on
                   the production technique involving the lowest emission and the best technical means available
                   for purifying effluent.
             (') If the effluent resulting from the production of endrin also contains isodrin, the limit values laid down above
                  shall also apply to the total discharges of aldrin, dieldrin, endrin and isodrin.
                 Isodrin is the chemical compound l,2,3,4,10,10-hexachlor-l,4,4a,5,8,8a-hexahydro-l,4-endo-5,8-endo-dimethano-

                                                             ANNEX      I
                                         Quality objective for aldrin, dieldrin and endrin
           1. The sum of these three substances must not exceed 5 ng/1 (five nanograms per litre) in fresh
               or sea water.
               The quality objective must be achieved by 1 January 1982.
          2. With the Commission's agreement, a Member State may set a less stringent quality objective
               than that mentioned above for a limited area, provided that the quality objective of 5 ng/1 is
               generally met in the waters outside that area.
                                                            ANNEX 11
                                                       Monitoring procedure
          1. Three zones must be determined for each area affected by the discharges:
               A. The immediate mixing zone next to the outlet, where hardly any dilution occurs.
               B. The dispersion zone, further away from the outlet, which is characterized by greater
                   diffusion and dilution of the discharges.
               C. The unaffected zone, where the discharges produce no measurable effect.
          2. A network of sampling points must be established in zone B, in such a way that the water
               samples are properly representative of the water quality for the entire zone.
               The frequency with which samples are taken must be sufficiently high to show changes in
               the state of the aquatic environment in zone B; in any case, samples should be taken at least
              once a week.
          3. The analytical method for determining the concentration of aldrin, dieldrin and endrin in
               the water samples shall be as follows:
               Gas chromatography with electron capture detection after extraction with the appropriate
               solvent and purification:
              — detection limit (1):        at least twice as low as the quality objective;
                               1
              — accuracy i ):               ± 50%;
                               1
              — precision ( ):              ± 30%.
