Environmental management systems

If you are implementing an environmental management system for your business, you'll need to compile a legislation directory. In Scotland you may need to add the Water Environment (Controlled Activities) (Scotland) Regulations 2005 (SI 2005/348) to your directory. These regulations require that all new developments use SuDS to control surface water run-off to the water environment, unless the run-off is from a single dwelling or is to coastal waters.


Scottish SuDS Legislation

The Water Environment (Controlled Activities) (Scotland) Regulations 2011 Read the section on the Pollution Control Regime for information on the levels of authorisation you may need if you intend to use SUDS in a development.

The Water Environment (Controlled Activities)(Scotland) Amendment Regulations 2013These regulations amend the rules governing a number of activities that affect the water environment, including works close to or in watercourses, certain agricultural activities and the storage and use of pesticides.

The Water Environment (Miscellaneous) (Scotland) Regulations 2017

The Regulations amend existing general binding rules (GBRs) 3, 9 to 13, 15, 17 to 20, 23 and 24, and inserts new GBRs 25 to 28. Consolidate the oil storage regulations into the Controlled Activities Regulations (CAR) and extend them to include storage in depots for the onward distribution of oil.
