The Water Environment (Controlled Activities) (Scotland) Amendment Regulations 2021 provide a regulatory framework for controlling activities which could have an adverse effect on Scotland’s water environment, including abstraction, impoundments, engineering, dredging, surface water drainage, and pollution, and are made in exercise of the The Water Environment (Controlled Activities) (Scotland) Regulations 2011 (CAR). Another part of these Regulations is to incorporate The Control of Pollution (Silage, Slurry and Agricultural Fuel Oil) (Scotland) Regulations 2003 (SSAFO) into CAR.
