CAS No 56-23-5(2)
| a Among the industrial establishments referred to under heading A, point 3, of Annex I, reference is made in particular to plants using carbon tetrachloride as solvent. | ||||
| b A simplified monitoring procedure may be introduced if annual discharges do not exceed 30 kg a year. | ||||
| c In view of the volatility of carbon tetrachloride and in order to ensure compliance with Article 3 (6), where a process involving agitation in the open air of effluent containing carbon tetrachloride is used, the Member States shall require compliance with the limit values upstream of the plant concerned; they shall ensure that all water likely to be polluted is taken fully into account. | ||||
| d It is not possible at present to adopt limit values for this sector. The Council is to adopt such limit values at a later date, acting on a Commission proposal. | ||||

Textual Amendments
F1 Deleted by Directive 2008/105/EC of the European Parliament and of the Council of 16 December 2008 on environmental quality standards in the field of water policy, amending and subsequently repealing Council Directives 82/176/EEC, 83/513/EEC, 84/156/EEC, 84/491/EEC, 86/280/EEC and amending Directive 2000/60/EC of the European Parliament and of the Council.
The reference method of measurement to be used for determining the presence of tetrachloride in effluents and water is gas chromatography.
A sensitive detector must be used when concentration levels are below 0,5 mg/l and in this case the determination limit(3) is 0,1 μg/l. For concentration levels higher than 0,5 mg/l a determination limit(4) of 0,1 mg/l is acceptable.
The accuracy and precision of the method must be ± 50 % at a concentration which represents twice the value of the determination limit(5).
Article 5 applies in particular to use of carbon tetrachloride in industrial laundries.

The ‘determination limit’xg of a given substance is the smallest quantity, quantitatively determinable in a sample on the basis of a given working method, which can still be distinguished from zero.
