The habitable zone lake surface is dependent on whether the lake is considered to have the geological sub-type “Peat” or “Non-Peat”.

The habitable zone lake surface area means the proportion of the reference conditions1 lake surface area from the shore to a depth 5 metres deeper than the depth to which light penetration to the lake bed would be sufficient to enable the growth of rooted plants (macrophytes) or bottom-living algae.

In the absence of field data to the contrary, the depth to which light penetration to the lake bed is sufficient to enable the growth of rooted plants (macrophytes) or bottom-living algae may be taken to be 2 metres for lakes with the geological sub-type of “Peat” and 7 metres for “Non-Peat” lakes. The lake habitable zone extends 5m below the level of light penetration to account for impacts on the aphotic habitat.

1 The reference conditions lake surface area means the natural lake surface area in the absence of any abstractions, discharges or other man-made influences

1 This parameter is the Environmental Quality Standard expressed as an annual average value (AA-EQS). Unless otherwise specified, it applies to the total concentrations of all isomers of the pollutant concerned.

2 This parameter is the Environmental Quality Standard expressed as a maximum allowable concentration (MAC-EQS). Where the MAC-EQS are marked as “not applicable”, the AA-EQS values are considered protective against short-term pollution peaks in continuous discharges since they are significantly lower than the values derived on the basis of acute toxicity.

3 For the group of priority substances covered by brominated diphenylethers listed in Decision 2455/2001/EC, an EQS is established only for congener numbers 28, 47, 99, 100, 153 and 154.

4 For cadmium and its compounds the EQS values vary dependent upon the hardness of the water as specified in five class categories (class 1: <40mg CaCO3/l, class 2: 40 to <50mg CaCO3/l, class 3: 50 to <100mg CaCO3/l, class 4: 100 to <200mg CaCO3/l and class 5: ≥200mg CaCO3/l).

5 DDT total comprises the sum of the isomers 1,1,1-trichloro-2,2 bis (p-chlorophenyl) ethane (CAS number 50-29-3; EU number 200-024-3); 1,1,1-trichloro-2 (o-chlorophenyl)-2-(p-chlorophenyl) ethane (CAS number 789-02-6; EU number 212-332-5); 1,1-dichloro-2,2 bis (p-chlorophenyl) ethylene (CAS number 72-55-9; EU number 200-784-6); and 1,1-dichloro-2,2 bis (p-chlorophenyl) ethane (CAS number 72-54-8; EU number 200-783-0).

6 If the Department does not apply standards for biota it shall introduce stricter standards for water in order to achieve the same level of protection as the standards for biota set out in regulation 4. The Department shall notify the European Commission of the reasons and basis for using this approach, the alternative standards used, the data and the methodology by which the alternative standards were derived and the categories of surface water to which they would apply.
