(2) If he determines that it is made in relation to a project which falls within Annex I, or a project which falls within Annex II and whose characteristics require that it should be made subject to an environmental assessment, he shall direct the applicant to supply him in such form as he may specify with the information referred to in Annex III to the Directive to the extent that he considers—
(a)that it is relevant to any stage of the procedure set out in this Part and to the specific characteristics of the project to which the application relates and of the environmental features likely to be affected by it; and
(b)that (having regard in particular to current knowledge and methods of assessment) the applicant may reasonably be required to gather that information,
and including at least—
(i)a description of the project comprising information on the site, design and size of the project;
(ii)a description of the measures envisaged in order to avoid, reduce and, if possible, remedy significant adverse effects;
(iii)the data required to identify and assess the main effects which the project is likely to have on the environment;
