# Commission Decision of 20 November 2008 on guidelines for the purpose of the risk-based animal health surveillance schemes provided for in Council Directive 2006/88/EC (notified under document number C(2008) 6787) (Text with EEA relevance) (2008/896/EC), Division 6.5.3: Examples of low risk for the spread of disease via water and due to the geographical proximity of farms and mollusc farming areas:

Extent: E+W+S+N.I.

(a)farms and mollusc farming areas with no discharge into natural waterways;
(b)farms and mollusc farming areas which disinfect, or in any other manner treat the water discharge, to prevent the spread of pathogens;
(c)farms and mollusc farming areas which discharge their water into public sewage systems provided that the public sewage system contains a form of treatment of the sewage water; however, if the sewage water is discharged into natural water ways without any treatment, such farms and mollusc farming areas should not be regarded as constituting a low likelihood;
(d)farms and mollusc farming areas with no discharge into waters with aquaculture or wild aquatic animals of species susceptible to the relevant listed disease(s);
(e)inland water basins, including ponds and lakes, which are isolated from other water sources; in determining whether the water basin should be regarded as isolated, consideration should be given to seasonal changes such as the possibility of any contact with other water sources through flooding;
(f)coastal farms and mollusc farming areas which are protected by a safe distance from other farms and mollusc farming areas keeping species which are susceptible to the same diseases as the species kept in the farm or mollusc farming areas concerned; what should constitute a safe distance needs to be determined by the competent authority taking into account factors such as the ability of the relevant pathogens to survive in open waters, the water currents, and the length of tidal excursions.
