(2) 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. (3) Inland surface waters encompass rivers and lakes and related artificial or heavily modified water bodies. (4) 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 10 [77] protective against short-term pollution peaks in continuous discharges since they are significantly lower than the values derived on the basis of acute toxicity. (5) Unless otherwise indicated, the biota EQS relate to fish. An alternative biota taxon, or another matrix, may be monitored instead, as long as the EQS applied provides an equivalent level of protection. For PAHs, the biota EQS refers to crustaceans and molluscs. For the purpose of assessing chemical status, monitoring of PAHs in fish is not appropriate. For Dioxins and dioxin-like compounds, the biota EQS relates to fish, crustaceans and molluscs, in line with section 5.3 of the Annex to Commission Regulation (EU) No. 1259/2011 of 2 December 2011 amending Regulation (EC) No. 1881/2006 as regards maximum levels for dioxins, dioxin-like PCBs and non-dioxin-like PCBs in foodstuffs (O.J. L 320, 3.12.2011, p. 18) (6) The EQS for this substance shall take effect from 22 December 2015, with the aim of achieving good surface water chemical status in relation to these substances by 22 December 2021 by means of programmes of measures included in updates of river basin management plans produced in accordance with Article 13 of the 2003 Regulations. (7) 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. (8) For Cadmium and its compounds the EQS values vary dependent upon the hardness of the water as specified in five class categories (Class 1: <40 mg CaCO3/l, Class 2: 40 to <50 mg CaCO3/l, Class 3: 50 to <100 mg CaCO3/l, Class 4: 100 to <200 mg CaCO3/l and Class 5: 200 mg CaCO3/l). (9) No indicative parameter is provided for this group of substances. The indicative parameter(s) must be defined through the analytical method. (10) For the group of priority substances of polyaromatic hydrocarbons (PAH), the biota EQS and corresponding AA-EQS in water refer to the concentration of benzo(a)pyrene, on the toxicity of which they are based. Benzo(a)pyrene can be considered as a marker for the other PAHs, hence only benzo(a)pyrene needs to be monitored for comparison with the biota EQS or the corresponding AA- EQS in water. (11) The EQS for this substance shall take effect from 22 December 2018, with the aim of achieving good surface water chemical status in relation to this substance by 22 December 2027 and preventing deterioration in the chemical status of surface water bodies in relation to this substance. (12) There is insufficient information available to set a MAC-EQS for these substances. (13) PCDD: Polychlorinated dibenzo-p-dioxins; PCDF: polychlorinated dibenzofurans; PCB-DL: dioxin-like polychlorinated biphynels; TEQ: toxic equivalents according to the World Health Organisation 2005 Toxic Equivalent Factors.” 5. The 2009 Regulations are amended in Schedule 6 by the substitution of the following Table for Table 13 as inserted by the 2015 Regulations: “Table 13 Watch list of substances for Union-wide monitoring as set out in Article 8b of Directive 2008/105/EC Name of substance/group of substances CAS number (1) EU number (2) Indicative analytical method (3) (4) Maximum acceptable method detection limit (ng/l) 17-Alpha-ethinylestradiol (EE2) 57-63-6 200-342-2 Large-volume SPE – LC – MS-MS 0.035 17 - Beta-estradiol (E2), Estrone (E1) 50-28-2, 53-16-7 200-023-8 SPE – LC-MS-MS 0.4 Macrolide antibiotics (5) SPE – LC-MS-MS 19 Methiocarb 2032 -65 -7 217-991-2 SPE – LC-MS-MS or GC-MS 2 Neonicotinoids (6) SPE – LC-MS-MS 8.3 [77] 11 Metaflumizone 139968-49-3 604-167-6 LLE – LC-MS-MS or SPE – LC-MS MS 65 Amoxicillin 26787-78-0 248-003-8 SPE – LC-MS-MS 78 Ciprofloxacin 85721-33-1 617-751-0 SPE – LC-MS-MS 89 (1) Chemical Abstracts Service.

EOGHAN MURPHY, Minister for Housing, Planning and Local Government. 12 [77] EXPLANATORY NOTE (This Note is not part of the Instrument and does not purport to be a legal interpretation.) These Regulations amend the European Communities Environmental Objectives (Surface Waters) Regulations 2009 (S.I. No. 272 of 2009), as amended by the European Communities Environmental Objectives (Surface Waters) (Amendment) Regulations 2012 (S.I. No. 327 of 2012) and the European Union Environmental Objectives (Surface Waters) (Amendment) Regulations 2015 (S.I. No. 386 of 2015). The purpose of the Regulations is to give effect to Commission Implementing Decision (EU) 2018/229 of 12 February 2018 establishing, pursuant to Directive 2000/60/EC of the European Parliament and of the Council, the values of the Member State monitoring system classifications as a result of the intercalibration exercise and repealing Commission Decision 2013/480/EU; and Commission Implementing Decision (EU) 2018/840 of 5 June 2018 establishing a watch list of substances for Union-wide monitoring in the field of water policy pursuant to Directive 2008/105/EC of the European Parliament and of the Council and repealing Commission Implementing Decision (EU) 2015/495. To ensure an acceptable level of comparability and consistency between Member States in the use of biological assessment methods and ecological quality ratios, a European-wide intercalibration exercise was undertaken. The results of these intercalibration exercises and intercalibrated values used in classification have been published as a series of Commission Decisions. The latest Decision contains a number of new intercalibrated methods and values for use in the classification of Irish surface waters, which are now given effect in these Regulations. The Regulations update existing environmental standards used in the assessment of ecological status, mainly by providing additional boundary values for existing environmental quality standards and the inclusion of a new environmental quality standard for total phosphorus in lakes and also correct some footnote errors. The Regulations also provide for an updated watchlist to monitor concentrations of emerging pollutants and other substances of concern in the aquatic environment.
