Information Leaflet 1: Your Permitted Development Rights
Environmental Impact Assessment (EIA) is needed for development projects which are likely to have significant effects on the environment. For a project which needs planning permission, EIA takes place as part of the preparation and consideration of the planning application.
The Planning (General Development) Order (Northern Ireland) 1993 (S.R. 1993 NO. 278) (the GDO) grants planning permission, without the need for a planning application, for the classes of development described as permitted development.
The Planning (Environmental Impact Assessment) Regulations (Northern Ireland) 1999 (S.R 1999 NO. 73) (the EIA Regulations) amend the GDO to ensure that it does not grant planning permission for certain types of development which is likely to have significant effects on the environment. Such development has to be the subject of a planning application. The application must be accompanied by an environmental statement (ES); a publicly-available document setting out the developer's own assessment of a projects likely significant effects on the environment.
