Article 5
1
The emission standards laid down in the authorisations granted pursuant to Article 4 shall determine:
a
the maximum concentration of a substance permissible in a discharge. In the case of dilution, the emission limit value laid down by the Directives referred to in Annex IX to Directive 2000/60/EC shall be divided by the dilution factor;
b
the maximum quantity of a substance permissible in a discharge during one or more specified periods of time, expressed, if necessary, as a unit of weight of the pollutant per unit of the characteristic element of the polluting activity (e.g. unit of weight per unit of raw material or per product unit).
2
For each authorisation, the competent authority of the Member State concerned may, if necessary, impose more stringent emission standards than those resulting from the application of the emission limit values laid down by the Directives referred to in Annex IX to Directive 2000/60/EC, taking into account in particular the toxicity, persistence and bioaccumulation of the substance concerned in the environment into which it is discharged.
3
If the discharger states that he is unable to comply with the required emission standards, or if this situation is evident to the competent authority in the Member State concerned, authorisation shall be refused.
4
Should the emission standards not be complied with, the competent authority in the Member State concerned shall take all appropriate steps to ensure that the conditions of authorisation are fulfilled and, if necessary, that the discharge is prohibited.
