Council Directive

of 12 June 1986

on limit values and quality objectives for discharges of certain dangerous substances included in List I of the Annex to Directive 76/464/EEC

(86/280/EEC) (repealed)

THE COUNCIL OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Economic Community, and in particular Articles 100 and 235 thereof,

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(1), and in particular Article 6 thereof,

Having regard to the proposal from the Commission(2),

Having regard to the opinion of the European Parliament(3),

Having regard to the opinion of the Economic and Social Committee(4),

Whereas, in order to protect the aquatic environment of the Community against pollution by certain dangerous substances, Article 3 of Directive 76/464/EEC introduces a system of prior authorization laying down emission standards for discharges of the substances in List I in the Annex thereto; whereas Article 6 of the said Directive provides that limit values shall be laid down for such emission standards and also quality objectives for the aquatic environment affected by discharges of these substances;

Whereas Member States are required to apply the limit values except in cases where they may employ quality objectives;

Whereas the dangerous substances covered by this Directive have been chosen mainly on the basis of the criteria adopted in Directive 76/464/EEC;

Whereas, since pollution due to the discharge of these substances into the aquatic environment is caused by a large number of industries, it is necessary to lay down specific limit values for discharges according to the type of industry concerned and to lay down quality objectives for the aquatic environment into which these substances are discharged;

Whereas the purpose of the limit values and quality objectives is to eliminate pollution of the various parts of the aquatic environment which might be affected by discharges of these substances;

Whereas such limit values and quality objectives must be laid down for this purpose and not with the intention of establishing rules pertaining to consumer protection or to the marketing of products from the aquatic environment;

Whereas, to enable Member States to demonstrate that the quality objectives are being met, provision should be made for reports to the Commission for each quality objective chosen and applied;

Whereas Member States should seek to ensure that the measures taken pursuant to this Directive do not have the effect of increasing soil or air pollution;

Whereas, moreover, for the purposes of effective implementation of this Directive, provision should be made for the monitoring by the Member States of the aquatic environment affected by discharges of the substances in question; whereas the powers to introduce such monitoring are not provided by Directive 76/464/EEC; whereas, since the specific powers have not been provided for in the Treaty, recourse should be had to Article 235 thereof;

Whereas, in the case of certain significant sources of pollution by these substances other than sources subject to Community limit values or national emission standards, specific programmes should be devised to eliminate the pollution; whereas the necessary powers to that effect have not been provided by Directive 76/464/EEC; whereas, since the specific powers have not been provided for in the EEC Treaty, recourse should be had to Article 235 thereof;

Whereas ground water can be excluded from the scope of this Directive since it is the subject of Directive 80/68/EEC(5);

Whereas, for the purposes of effective implementation of this Directive, it is important that the Commission should forward to the Council, every five years, a comparative assessment of its implementation by the Member States;

Whereas this Directive will have to be amended and supplemented, on proposals from the Commission, in line with developments in scientific knowledge relating principally to the toxicity, persistence and accumulation of the substances referred to in living organisms and sediments, or in the event of an improvement in the best technical means available; whereas it is necessary, for that purpose, to provide for additions to this Directive, relating to measures in respect of other dangerous substances, and for amendments to the content of the Annexes,

HAS ADOPTED THIS DIRECTIVE:

Article 1U.K.

1.This Directive:

2.This Directive applies to the waters referred to in Article 1 of Directive 76/464/EEC, with the exception of ground water.

Article 8U.K.

This Directive is addressed to the Member States.

ANNEX IU.K.GENERAL PROVISIONS

This Annex is divided into three headings which set out the general provisions applicable to all the substances concerned:

The general provisions are amplified and supplemented in Annex II by a series of specific provisions applicable to individual substances.

HEADING ALimit values, dates set for compliance therewith and procedures for monitoring dischargesU.K.

1.

The limit values and the dates set for compliance therewith are set out in Annex II, under heading A, in respect of the different types of industrial plant concerned.

2.

The quantities of substances discharged are expressed in terms of the quantity of substances produced, processed or used by the industrial plant during the same period or, in accordance with Article 6 (1) of Directive 76/464/EEC, of another parameter characteristic of that activity.

3.

Limit values for industrial plants which discharge substances referred to in Article 2 (a) and which are not mentioned under heading A in Annex II will, where necessary, be determined by the Council at a later stage. Meanwhile, the Member States will independently set, in accordance with Directive 76/464/EEC, emission standards for discharges of such substances. Such standards must take into account the best technical means available and must not be less stringent than the most nearly comparable limit value set out under heading A in Annex II.

This paragraph will also apply where an industrial plant has activities other than those for which limit values have been set under heading A in Annex II and which are likely to be a source of discharges of the substances referred to in Article 2 (a).

4.

Limit values expressed as concentrations which, in principle, must not be exceeded are given in Annex II under heading A, in respect of the industrial plants concerned. In no instance may limit values expressed as maximum concentrations, when they are not the only values applicable, be greater than limit values expressed by weight divided by water requirements per element characteristic of the polluting activity. However, because the concentration of these substances in effluents depends on the volume of water involved, which varies for different processes and plants, the limit values expressed in terms of the weight of the substances discharged in relation to the parameters characteristic of the activity given under heading A in Annex II, must be complied with in all cases.

5.

A monitoring procedure must be instituted to check whether the discharges of the substances referred to in Article 2 (a) comply with the emission standards.

This procedure must provide for the taking and analysis of samples and for measurement of the flow of the discharge and the quantity of substances handled or, where appropriate, measurement of the parameters characteristic of the activity causing pollution as listed in Annex II, heading A.

In particular, should the quantity of substances handled be impossible to determine, the monitoring procedure may be based on the quantity of substances that may be used as a function of the production capacity on which the authorization was based.

6.

A sample representative of the discharge over a period of 24 hours must be taken. The quantity of substances discharged over one month must be calculated on the basis of the daily quantities of substances discharged.

Annex II may, however, lay down for discharges of certain substances quantitative thresholds below which the Member States may apply a simplified monitoring procedure.

7.

The sampling and flow measurement provided for in paragraph 5 shall normally be effected at the points of application of the limit values provided for in Article 3 (2).

However, where necessary to ensure that the measurements comply with the requirements of heading C of the Annexes, a Member State may allow the sampling and flow measurement to be effected at another point before that at which the limit values apply, provided that:

  • all waters discharged from the plant that may have been polluted by the substance in question are taken into account by those measurements,

  • regular checks show that the measurements are fully representative of the quantities discharged at the points of application of the limit values or are always higher.

HEADING BQuality objectives, dates set for compliance therewith and procedure for monitoring compliance with themU.K.

1.

For those Member States which opt for the exception provided for in Article 6 (3) of Directive 76/464/EEC, the emission standards which they must establish and apply, pursuant to Article 5 of that Directive, will be fixed so that the appropriate quality objective or objectives from those fixed pursuant to paragraphs 2 and 3 below is or are complied with in the area affected by discharges of the substances referred to in Article 2 (a). The competent authority will determine the area affected in each case and will select from the quality objectives fixed pursuant to paragraphs 2 and 3 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 this Directive is to eliminate all pollution.

2.

With a view to eliminating pollution, as defined in Directive 76/464/EEC, and pursuant to Article 2 of that Directive, the quality objectives and dates set for compliance therewith are set out under heading B in Annex II.

3.

Unless otherwise specified under heading B in Annex II, all the concentrations mentioned as quality objectives refer to the arithmetic mean of the results obtained over a year.

4.

Where more than one quality objective is applied to waters within one area, the quality of the water must be sufficient to comply with each of those objectives.

5.

For each authorization granted pursuant to this Directive, the competent authority will specify the detailed rules, monitoring procedures and dates for ensuring compliance with the quality objective or objectives concerned.

6.

In accordance with Article 6 (3) of Directive 76/464/EEC, the Member States will, 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.

7.

Samples must be taken at a point sufficiently close to the discharge point to be 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, having regard in particular to natural variations in hydrological conditions.

HEADING CReference methods of measurement and limit of detectionU.K.

1.

The definitions given in Council Directive 79/869/EEC of 9 October 1979 concerning the methods of measurement and frequencies of sampling and analysis of surface water intended for the abstraction of drinking water in the Member States(7) will apply in the context of this Directive.

2.

The reference methods of measurement to be used for determining the concentration of the substances in question and the limit of detection for the environment concerned are set out under heading C in Annex II.

3.

The limit of detection, the accuracy and the precision of the method are specified for each substance under heading C in Annex II.

4.

Effluent flow measurements must be carried out to an accuracy of ± 20 %.

CAS — 107-06-2

Heading A (59): Limit values for emission standards (37) U.K.

a

The purified EDC production capacity includes that fraction of the EDC which is not cracked in the vinyl chloride (VC) production unit associated with the EDC production unit and which is recycled to the EDC purification section of the plant.

Production or processing capacity is the capacity authorized by administration or, failing that, the highest annual quantity produced or processed over the four years prior to the granting or review of the authorization. The capacity authorized by the administration should not differ greatly from actual production.

b

A simplified monitoring procedure may be introduced where annual discharges do not exceed 30 kg/year.

c

These limit values relate:

  • for sectors (a) and (b), to purified EDC production capacity in tonnes,

  • for sector (c), to EDC processing capacity expressed in tonnes.

However, in the case of sector (b), if the processing and utilization capacity is greater than the production capacity, the limit values shall be applied in relation to the global processing and utilization capacity. If there are several plants on the same site, the limit values shall apply to the plants taken together.

d

Without prejudice to the provisions of heading A (4) in Annex I, these concentration limits relate to the following reference volumes:

(a)

2 m 3 /tonne of purified EDC production capacity;

(b)

2,5 m 3/ tonne of purified EDC production capacity;

(c)

2,5 m 3 /tonne of EDC processing capacity.

e

The limit values take account of all diffuse internal sources and/or of EDC used as a solvent within the industrial production site; this will ensure a reduction in EDC discharges of more than 99 %.

Nevertheless, the combination of the best available technology and the absence of any diffuse internal source enables reduction amounts greater than 99,9 % to be achieved.

On the basis of the experience acquired in the application of the present measures, the Commission will present to the Council in good time proposals for more severe limit values to be applied from 1998.

f

Where a Member State takes the view that, owing to the integration of EDC production with the manufacture of other chlorinated hydrocarbons, an EDC production process is unlikely to comply with these limit values by the 1 January 1993 deadline, it must advise the Commission thereof before 1 January 1991. A programme for the reduction of EDC discharges which will enable these limit values to be complied with by 1 January 1997 will be submitted to the Commission no later than 31 December 1993. The following limit value must, meanwhile, be complied with as at 1 January 1993:

  • 40 g EDC/tonne of purified EDC produciton capacity (monthly and daily averages).

The limit value expressed as concentration is deduced on the basis of the volume of water discharged by the plant(s) concerned.

g

The production of the folllowing substances specifically is involved here: ethylene diamine, ethylene polyamine, 1.1.1.-trichloroethane, trichloroethylene and perchloroethylene.
