Notes to Table A:
(1)The maximum allowable concentrations are to help manage short-term incidents. We are proposing that they are not used to classify the chemical status of surface waters.
(i) This parameter is the Environmental Quality Standard expressed as an annual average value ( EQS- AA). Unless otherwise specified, it applies to the total concentration of all isomers.
(ii) Inland surface waters encompass rivers and lakes and related artificial or heavily modified water bodies.
(iii) This parameter is the Environmental Quality Standard expressed as a maximum allowable concentration ( EQS- MAC). 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.
(iv) For the group of priority substances covered by brominated diphenylethers (No. 5) listed in Decision 2455/2001/EC, an EQS is established only for congener numbers 28, 47, 99, 100, 153 and 154.
(v) For Cadmium and its compounds (No. 6) the EQS values vary dependent upon the hardness of the water as specified in five class categories (Class 1: <40 mg CaCO 3/l, Class 2: 40 to <50 mg CaCO 3/l, Class 3: 50 to <100 mg CaCO 3/l, Class 4: 100 to <200 mg CaCO 3/l and Class 5: =200 mg CaCO 3/l).
(vi) This substance is not a priority substance but one of the other pollutants for which the EQS are identical to those laid down in the legislation that applied prior to the entry into force of this Directive.
(vii) 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).
(viii) If Member States do not apply EQS for biota they shall introduce stricter EQS for water in order to achieve the same level of protection as the EQS for biota set out in Article 2(1a). They shall notify the Commission and other Member States, through the Committee referred to in Article 21 of Directive 2000/60/EC, of the reasons and basis for using this approach, the alternative EQS for water established, including the data and the methodology by which they were derived, and the categories of surface water to which they would apply.
(ix) For the group of priority substances of polyaromatic hydrocarbons ( PAH) (No. 28), each individual EQS is applicable, i.e., the EQS for Benzo(a)pyrene, the EQS for the sum of Benzo(b)fluoranthene and Benzo(k)fluoranthene and the EQS for the sum of Benzo(g,h,i)perylene and Indeno(1,2,3-cd)pyrene must be met.
