Proposal  for a Council  Directive  on the limit  values  for discharges  of aldrin,  dieldrin  and 
endrin  into  the aquatic  environment 
THE  COUNCIL  OF THE  EUROPEAN 
COMMUNITIES, 
Having  regard  to Council  Directive  76/464/EEC  of 
4 May  1976  on pollution  caused  by certain  dangerous 
substances  discharged  into  the aquatic  environment  of 
the Community  ('),  and  in particular  Article  6 
thereof, 
Having  regard  to the proposal  from  the Commission, 
Having  regard  to the  opinion  of the  European  Par-
liament, 
Having  regard  to the  opinion  of the  Economic  and 
Social  Committee, 
Whereas  Article  6 of Directive  76/464/EEC  provides 
for limit  values  to be laid  down  for  the  emission 
standards  relating  to discharges  of the  substances  in 
List I of the Annex  to that  Directive; 
Whereas  aldrin,  dieldrin  and  endrin  are  halogenated 
organic  compounds;  whereas  they  are included  in List 
(') OJ No L 129,  18. 5. 1976,  p. 23. I by virtue  of their  toxicity,  persistence  and  bioaccu-
mulation; 
Whereas  since  that  same  Directive  also  provides  for 
quality  objectives  to be laid  down,  the  latter  are 
defined  in Council  Directive  . 
Whereas,  since  the  water  pollution  caused  by the 
discharge  of  these  substances  emanates  almost 
entirely  from  plants  which  produce  them  and  from 
the mothproofing  of wool  and  wool  products,  limit 
values  should  be  fixed  for  these  two  industrial 
activities  and  discharges  should  be made  subject  to a 
system  of prior  authorization; 
Whereas  it should  be laid  down  that  Member  States 
should  fix the emission  standards  and  time  limits  in 
compliance  with  the  limits  determined  by  the 
Council; 
Whereas  provision  should  be made  for  the  authori-
zation  of discharges  of substitute  products  in order  to 
avoid,  a new  danger  to the  Community  aquatic 
environment; 
Whereas  ground  water  is to be covered  by a special 
Directive  and  is not therefore  included  in the scope  of 
this Directive, 
No C 146/6  Official  Journal  of the  European  Communities  12.6.79 
HAS  ADOPTED  THIS  DIRECTIVE:

ANNEX  I 
The limit  values  which  the  emission  standards  must  not  exceed,  the  time  limits  and  sampling 
frequencies  to be applied  to aldrin,  dieldrin  and  endrin  used  in industrial  plants 
1, Exsting  plants  which  manufacture  aldrin,  dieldrin  and/or  endrin 
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 m3  per  month, 
Q —  current  outflow  expressed  in m8  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, 
Q0 = 175  m3  per kg of pure  dieldrin  employed, 
Q —  quantity  of water  expressed  in m3  per kg of pure  dieldrin  employed. 
No C 146/8 Official  Journal  of the  European  Communities 12. 6. 79 
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-
naphthalene.

Gas chromatography  with  electron  capture  detection  after  extraction  with  the  appropriate 
solvents  and  purification: 
— limit  of detection  (*): the minimum  limit  shall  be 10 times  lower  than  the  monthly  con-
centration  required  at the sampling  point; 
where  the emmission  standard  is set at zero,  the detection  limit  must  be 10 ng/1; 
— accuracy  ('): ± 50 %; 
— precision  0): ± 30 %.

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; 
— accuracy  i1): ±  50%; 
— precision  (1): ±  30%.
