EXPLANATORY NOTE.

These Regulations prescribe quality standards to be applied by local and sanitary authorities when licensing discharges of effluents containing carbon tetrachloride (CC1

4

), DDT and pentachlorophenol to waters or to sewers under the provisions of the

Local Government (Water Pollution) Act, 1977

as amended by the

Local Government (Water Pollution) (Amendment) Act, 1990

. The Regulations give effect to Council Directive No. 86/280/EEC on limit values and quality objectives for discharges of certain dangerous substances included in List I of the Annex to Council Directive 76/464/EEC.

5. Without prejudice to the provisions of article 4, a local authority or sanitary authority shall ensure that the best technical means are used where necessary for the elimination of pollution in granting a licence for the discharge of trade effluent from a new plant.

6. A local authority or sanitary authority shall review a licence in respect of trade effluent referred to in article 4 at least every four years.

7. A local authority or sanitary authority shall ensure as far as possible that the granting of a licence will not result in an increase in the pollution, by the substances in respect of which quality standards are prescribed in these Regulations, of other environmental media, in particular soil and air.
