In addition, the results of the environmental (European Commission (EC), 2010); impact assessment (EIA) undertaken on marine mammals based on the proposed activities, including construction, operation and decommissioning are detailed.

Regulation 39(1) of the Habitats Regulations provides that “it is an (Marine Scotland, 2012). offence, with certain exceptions, to: 15 An activity that might otherwise constitute an offence may only be granted a licence if it can be demonstrated (a) deliberately or recklessly to capture, injure or kill a wild animal of a European protected species; that by granting the licence the licensing authority remains fully compliant with the requirements of the Habitats Regulations. In order to achieve this it must be demonstrated that: (b) deliberately or recklessly The activity is one of the licensable purposes listed in Regulation 44; (i) to harass a wild animal or group of wild animals of a European protected species; There is no satisfactory alternative; and (ii) to disturb such an animal while it is occupying a structure or place which it uses for shelter or protection; That the action authorised will not be detrimental to the maintenance of the population of the species concerned at a favourable conservation status in their natural range (SNH, 2012a). (iii) to disturb such an animal while it is rearing or otherwise caring for its young; 16 It is predicted that should consent be granted under Section 36 for the proposed development an application for (iv) to obstruct access to a breeding site or resting place of such an animal, or otherwise to deny the a European protected species Licence will be required as all species of whale, porpoise and dolphin are listed animal use of the breeding site or resting place; under Annex IV of the Habitats Directive (SNH, 2012a).
