3. Safety, Health and Environment (SHE) Group SHE Code 41: ‘Controlling Pollution to Air, Water or Land’

4. Why a code to control pollution? STFC requires regulatory authorisation to discharge hazardous substances into site drains, or to air, land or water courses. The use of substances which deplete the ozone layer or act as greenhouse gasses may also require authorisation and the equipment using them should be carefully designed and maintained.

5. Key Features Always reduce any liquid or gaseous discharges to a minimum when planning new work or experiments. Environmental issues must be included as part of the risk assessment process. Controls should be implemented which reduce hazardous discharges as far as reasonably practicable. The assessment should include storage issues, for example bunding, as well as accidental spills.

6. Where discharges to air or drain are hazardous consult STFC Environment Officer/SHE Group in advance to see if regulatory authorisation is required. NEVER discharge hazardous waste to surface water drains. Ensure all liquid waste is directed to the right drain. STFC drains use the following marking scheme: Surface water – Blue Radioactive waste - Yellow/Black Foul (Domestic) – Red Trade waste – Yellow Key features

7. All use of Fluorinated Greenhouse Gases, for example HFCs, PFCs, SF 6, should be listed in site F-Gas register which is maintained by site Estates Groups. Installation and maintenance of equipment using F- Gases to be undertaken by certified personnel. All environmentally sensitive liquids stored outside buildings should, in general, be stored in bunded areas. Stores of oil greater than 200L must be bunded, the secondary container should hold at least 110% of the capacity. All Environmental incidents should be reported in SHE enterprise.

8. Additional information Where STFC modifies or stores waste, it may require additional regulatory authorisation. For example: –Composting –Bailing cardboard Contact SHE Group for more information.
