My statutory powers in relation to the licensing of fish farming derive from the Fisheries Acts 1959 and 1980 and the Foreshore Act 1933.
The preparation and publication of comprehensive Environmental Impact Statements is mandatory for all licence applications for marine salmonid farms with a proposed annual output of over 100 tonnes and for freshwater salmonid installations.
The threshold limits, consultation procedures and data requirements, which are very strict by comparison to other EU countries, are set out under the European Communities (Environmental Impact Assessment) Regulation 1989 (SI 349/1989) and the Fisheries (Environmental Impact Assessment) Regulations 1990 (SIs 40 and 41/1990).
