asked the Minister for the Environment if he will outline Government policy with regard to the environmental impact of mineral exploration and development; the implications of the Mineral Development Act, 1940 in this regard; whether he has made any representations to the Minister for Energy to have that Act amended or to introduce legislation or regulations concerning the environmental impact of all stages of prospecting and mining; and if he will make a statement on the matter.

Mineral exploration and development must be carried out in accordance with acceptable environmental standards, determined in the context of relevant statutory environmental controls.
Prospecting for and mining of minerals requires the authorisation of the Minister for Energy under the Minerals Development Acts, 1940 to 1979. However, it is primarily a matter for a local authority in whose area mining activities are proposed to ensure, in the context of planning and other statutory controls, that they are managed in a manner which avoids or minimises adverse effects on the environment.
Since 1977, planning law has specifically required an environmental impact assessment for certain mining development which could give rise to pollution or nuisance. Further requirements as to environmental impact assessment, in line with EC Directive 85/337, were notified by my Department in July 1988. An environmental impact study will accordingly have to be prepared for any mining project for which planning permission is sought which is adjudged likely to have significant effects on the environment.
By identifying the potential impact of a development clearly and comprehensively, such studies should result in a better assessment of the action necessary to prevent or limit environmental damage. Work is in progress in my Department on measures to give statutory effect to this Directive in respect of mining and other development, and if is hoped to finalise these measures as soon as possible.
