Question referred

Are Articles 2(a) and 3(2)(a) of Directive 2001/42/EC ¹ on the assessment of the effects of certain plans and programmes on the environment to be interpreted to the effect that a regulatory order containing various provisions on the installation of wind turbines, including measures on safety, inspection, site restoration and financial collateral and permitted noise levels set having regard to town and country planning zones, such provisions setting a framework for the grant of administrative consent allowing a developer to install and operate installations which are automatically subject under national law to an assessment of their effects on the environment, must be considered to be a ‘plan or programme’ within the meaning of those articles?
