“Member States shall adopt all measures necessary to ensure that, before consent is given, projects likely to have significant effects on the environment by virtue inter alia of their nature, size or location are made subject to a requirement for development consent and an assessment with regard to their effect. These projects are defined in Article 4.”
“(2) Whereas, pursuant to Article 130r(2) of the Treaty, Community policy on the environment is based on the precautionary principle and on the principle that preventive action should be taken, that environmental damage should as a priority be rectified at source and that the polluter should pay; (3) Whereas the main principles of the assessment of the environmental effects should be harmonised and whereas the Member States may lay down stricter rules to protect the environment; ,… (5) Whereas projects for which an assessment is required should be subject to a requirement for development consent; whereas the assessment should be carried out before such consent is granted;”
“(2) Screening opinions of the local planning authority Where it appears to the local planning authority by whom or on whose behalf an enforcement notice is to be issued that the matters constituting the breach of planning control comprise or include Schedule 1 development or Schedule 2 development they shall, before the enforcement notice is issued, adopt a screening opinion.”
“General considerations 32. The local planning authority must screen every application for Schedule 2 development in order to determine whether or not EIA is required. This determination is referred to as a “screening opinion”
“The number of cases of such developments will be a very small proportion of the total number of Schedule 2 developments. It is emphasised that the basic test of the need for EIA in a particular case is the likelihood of significant effects on the environment. It should not be assumed, for example, that conformity with a development plan rules out the need for EIA, nor is the amount of opposition or controversy to which a development gives rise relevant to this determination, unless the substance of opponents’ arguments reveals that there are likely to be significant effects on the environment.”
