COMMISSION 
Proposal for a Council Directive amending and supplementing Annex II to Directive 
86/280/EEC on limit values and quality objectives for discharges of certain dangerous 
substances included in List I of the Annex to Directive 76/464/EEC 
COM(88) 432 final 
(Submitted by the Commission on 19 September 1988) 
(88/C 253/05) 
THE COUNCIL OF THE EUROPEAN COMMUNITIES, 
Having regard to the Treaty establishing the European 
Economic Community, and in particular Article 130s 
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 ('), and in particular Articles 6 and 12 
thereof, 
Having regard to the proposal from the Commission, 
Having regard to the opinion of the European 
Parliament, 
Having regard to the opinion of the Economic and 
Social Committee, 
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 the 
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 Council Directive 86/280/EEC (2), as amended 
by Directive 88/347/EEC (3), needs to be adjusted and 
supplemented, on proposals from the Commission, in 
line with developments in scientific knowledge relating 
principally to the toxicity, persistence and accumulation 
of these substances in living organisms and sediments, or 
in the event of an improvement in the best technical 
means available, 
HAS ADOPTED THIS DIRECTIVE: 
Article 1 
Annex II to Directive 86/280/EEC is hereby amended as 
set out in the Annex hereto. 
Article 2 
1. The Member States shall bring into force the laws, 
regulations and administrative provisions necessary to 
comply with this Directive by 1 January 1990. They shall 
forthwith inform the Commission thereof. 
2. Member States shall communicate immediately to 
the Commission the texts of the main provisions of 
national law which they adopt in the field governed by 
this Directive. 
Article 3 
This Directive is addressed to the Member States.

(') A simplified monitoring procedure may be introducted if annual discharges do not exceed 30 kg/year. Where this 
applies to the users referred to in (b), the concentration limits are 1 mg/1 (monthly average) and 2 mg/1 (daily 
average). 
(2) In view of the volatility of trichloroethylene and in order to ensure compliance with Article 3(6), where the process 
used involves open-air agitation of the effluents containing trichloroethylene, the Member States must require 
compliance with the limit values upstream of the plants concerned; they must ensure that all waters likely to be 
polluted are properly taken into account. 
(') The industrial plants referred to in Heading A(3) in Annex I include those making any use of TRI as a solvent, in 
particular for extracting fats or aromas. 
(4) For sector (a), the limit values for TRI discharges are given in relation to the total TRI + PER production capa­
city. 
In respect of the four-yearly review of the discharge authorizations referred to in the second subparagraph of 
Article 3(3), the production capacity to be taken into consideration is based on the highest annual production 
recorded during the four years which have elapsed prior to the granting or review of the discharge authorization 
concerned. 
(') Notwithstanding the provisions of Heading A(4) in Annex I, the TRI concentration limits are given in relation to 
the following reference volumes: 
(a) 5 mVtonne of TRI + PER produced 
(b) 10 mVtonne of metal treated 
(c) 0,25 mVtonne of goods treated. 
For sectors (b) and (c), the provisions of Heading A(4) in Annex I are applied by taking the product of the 
concentration limit multiplied by the reference volume. 
(*) A further period of five years is granted to existing plants equipped with machines of the 'open' type which do not 
enable them to comply with this limit value.

(c) 0,25 mVtonne of goods treated 
(d) 10 mVtonne of metal treated. 
For sectors (c) and (d), the provisions of Heading A(4) in Annex I are applied by taking the product of the

(') A further period of five years is granted to existing plants equipped with machines of the 'open' type which do not 
enable them to comply with this limit value. 
(') At present it is not possible to lay down limit values for this sector. The Council will do so at a later date, on a 
proposal from the Commission. For the time being, the Member States will lay down national emission standards 
in accordance with the provisions of Heading A(3) in Annex I.

XI. Specific provisions relating to Trichlorobenzene (TCB) (117, 118) (') 
Standstill: The concentration of TCB in the water environment, sediments and/or molluscs and/or 
shellfish and/or fish must not increase significantly with time. 
(') TCB may occur as one of the following three isomers: 
— 1,2,3-TCB CAS-87-61-6 
— l,2,4-TCBCAS-120-82-l (No 118) 
— l,3,5-TCBCAS-180-70-3. 
Technical TCB (No 117) is a mixture of these three isomers, with a preponderance of 1,2,4-TCB, and may 
also contain small quantities of di- and tetrachlorobenzene. 
In any case, these provisions apply to the total TCB (the sum of the three isomers).

(2) The industrial plants referred to in Heading A(3) in Annex I include those making non-captive use of TCB, in 
particular as a solvent or base for dyes in the textile industry. 
(5) The limit values for discharges of TCB (sum of the three isomers) are given: 
— for sector (a): in relation to the total TCB production or processing capacity, 
— for sector (b): in relation to the total production or processing capacity for mono- and dichlorobenzenes. 
(4) Notwithstanding the provisions of Heading A(4) in Annex I, the concentration limits are given in relation to the 
following reference volumes: 
For sector (a): 10 m3 per tonne of TCB produced or processed, 
For sector (b): 10 m3 per tonne of chloro- and dichlorobenzenes produced or processed.
