§ Mr. KynochTo ask the Secretary of State for Scotland what progress he has made with the identification of sensitive areas and high natural dispersion areas in connection with the urban waste water treatment directive; and if he will make a statement.
§ Sir Hector MonroThe Scottish waters identified as sensitive areas and high natural dispersion areas —HNDAs —in connection with the urban waste water treatment directive are set out in the table.
The general requirement of the directive is that all discharges of urban waste water from a population equivalent of 2,000 or more to freshwaters or estuaries, or 10,000 or more to coastal waters, should receive secondary treatment.
In areas identified as sensitive, more stringent treatment will be required while in HNDAs, the directive permits less stringent treatment—but at least primary treatment. The adequacy of less stringent treatment to prevent adverse effects on the environment requires to be demonstrated by comprehensive studies and confirmed by subsequent monitoring.
A map showing the locations of these areas has been prepared and will be forwarded to the European Commission. It will be made available for public inspection at the offices of the river purification authorities and meanwhile has been placed in the Library of the House.
