APP2026-00001781 - Kames Fish Farming Limited: Loch Tay, Acharn, Aberfeldy, Perth and Kinross, PH25 2HP - EASR Variation

Overview

SEPA is one of a number of organisations regulating finfish aquaculture. Anyone who operates a fish farm must have an authorisation from SEPA, under The Environmental Authorisations (Scotland) Regulations 2018 (EASR). When we receive an application for a new fish farm or to modify the operation of an existing fish farm, as part of our determination we will consider the risks to the water environment (including potential impacts to species and habitats), and the interests of other users of the water environment.   

If we decide to grant or vary an authorisation it will include conditions to protect the water environment. The person authorised to carry on the activity must do so in accordance with the conditions of the authorisation. 

We may also review the conditions of an existing authorisation from time to time to make sure they are still effective in achieving these aims.
