Directive 1982/176 - Limit values and quality objectives for mercury discharges by the chlor-alkali electrolysis industry - Main contents

Maximum concentrations of certain industrial Mercury discharges

Directive 82/176/EEC sets limit values for mercury emissions standards in order to reduce discharges of mercury into waters in the European Union (EU). Furthermore, it establishes objectives for quality, methods of measurement and a monitoring procedure. This Directive is applicable until 22 December 2012.

ACT

Council Directive 82/176/EEC of 22 March 1982 on limit values and quality objectives for mercury discharges by the chlor-alkali electrolysis industry [See amending acts].

SUMMARY

This Directive complements the provisions regarding the discharge of dangerous substances in the aquatic environment in the European Union.

Objectives

This Directive:

• - 

  establishes limit values for emission standards for mercury for discharges from industrial establishments * (See Annex 1);
• - 

  sets quality objectives concerning mercury for the aquatic environment;
• - 

  establishes deadlines for compliance with the conditions set out in authorisations granted by the competent authorities in the Member States for existing discharges (See Annex II);
• - 

  sets reference methods of measurement enabling the mercury content in discharges and in waters to be determined (See Annex III);
• - 

  establishes a monitoring procedure for discharges (See Annex IV);
• - 

  invites Member States to harmonise their monitoring procedures in the event that discharges affect the waters of several Member States.

Waters

This Directive covers:

• - 

  inland surface waters;
• - 

  territorial waters; and
• - 

  internal coastal waters.

Groundwater is the subject of a specific directive. Consequently, it does not come under the scope of this Directive.

Mercury

‘Mercury’ is defined as:

• - 

  the chemical element ‘mercury’;
• - 

  the mercury contained in any of its compounds.

Authorisation

All discharges require the prior authorisation of the Member State concerned. This authorisation must set the emission standards that are at least as stringent as those provided for in this Directive.

Member States may grant authorisations for new plants only if these authorisations contain a reference to the standards corresponding to the best technical means available for preventing discharges of mercury.

Monitoring

Member States must ensure the monitoring of the aquatic environment affected by discharges from industrial establishments. When the discharges affect the waters of several Member States, the Member States concerned must cooperate in order to harmonise monitoring procedures.

The monitoring procedure is instituted in order to check whether the discharges comply with the emission standards which have been fixed in accordance with the limit values laid down in Annex I. This procedure provides for the taking each day of a sample, the measurement of the mercury concentration and the measurement of the total flow of the discharge over a 24-hour period.

The daily quantity of mercury discharged is calculated at the end of the month. The monthly total is then divided by the installed chlorine production capacity.

Context

This Directive is replaced by Directive 2008/105/EC establishing environmental quality standards applicable to surface water.

Key Terms of the Act

• - 

  Industrial establishment: the chlor-alkali electrolysis industry which uses mercury cathode cells.
