(This note is not part of the Regulations)
These Regulations prescribe a system for classifying the quality of controlled waters which are coastal or brackish waters and which need protection or improvement in order to support shellfish life and growth.
The classification SFW reflects the mandatory values assigned by Directive 79/923/EEC (the quality required of shellfish waters) to the parameters listed in the Schedule to these Regulations.
The Regulations also incorporate the reference methods of measurement, and the minimum frequency required for sampling and analysis, laid down in that Directive for those parameters.
The Regulations, together with the Surface Waters (Shellfish) Directions 1997, transpose Directive 79/923/EEC in relation to England and Wales. Copies of the Surface Waters (Shellfish) Directions 1997 may be obtained from:
