COMMISSION IMPLEMENTING DECISION (EU) 2024/365

of 23 January 2024

laying down rules for the application of Directive (EU) 2020/2184 of the European Parliament and of the Council as regards methodologies for testing and accepting starting substances, compositions and constituents to be included in the European positive lists

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Directive (EU) 2020/2184 of the European Parliament and of the Council of 16 December 2020 on the quality of water intended for human consumption [(1)](#ntr1-L_202400365EN.000101-E0001), and in particular Article 11(2), point (a), thereof,

Whereas:

|  |  |
| --- | --- |
| (1) | Testing and acceptance methodologies should be established for assessing the safe use of starting substances, compositions and constituents. |

|  |  |
| --- | --- |
| (2) | Inclusion or removal of an entry in a European positive list should be based on the identification of the starting substance, composition or organic cementitious constituent and the identification of its intended use. The physico-chemical properties of the starting substance, composition or organic cementitious constituent necessary for carrying out migration testing should be established. The starting substance, composition or organic cementitious constituent should be tested for migration. |

|  |  |
| --- | --- |
| (3) | Inclusion or removal of an entry in a European positive list should be based on the identification of chemical species that are relevant for the acceptance methodology, or risk assessment, because they may have an impact on the safe use of a material or product, such as an impurity, the constituent of a starting substance or a degradation product. These relevant chemical species should be determined on the basis of the information on the identification of the starting substance, composition or constituent and on the basis of its intended use as well as the results of migration testing. The toxicological properties of these relevant chemical species should also be identified. |

|  |  |
| --- | --- |
| (4) | For proportionality and efficiency reasons, testing for physico-chemical properties and toxicological properties as well as risk assessment should be more limited if a similar assessment has already been carried out at Union level within a reasonable period of time or if the substance has a stringent classification in Part 3 of Annex VI of Regulation (EC) No 1272/2008 of the European Parliament and of the Council [(2)](#ntr2-L_202400365EN.000101-E0002) or the applicant proposes such classification. For proportionality reasons, the testing requirements for toxicological properties should be stricter where there is a high exposure to a certain substance through migration. |

|  |  |
| --- | --- |
| (5) | In order to respect the precautionary principle and in order to cover the potential for significant exposure over a long period of time, the acceptance methodology should be based on a worst-case risk assessment of each relevant chemical species. The risk assessment should consider migration, including release, under the worst foreseeable conditions of use. In particular, the risk assessment should consider the expected long-term exposure to materials or products in contact with water intended for human consumption and, in the case of metallic compositions, the differences in the properties, such as composition and corrosivity, of all water in the Union intended for human consumption. |

|  |  |
| --- | --- |
| (6) | Economic operators and relevant authorities should be allowed sufficient time to adapt their national methodologies to the methodologies set out in this Decision. The application of this Decision should therefore be deferred. |

|  |  |
| --- | --- |
| (7) | The measures provided for in this Decision are in accordance with the opinion of the Committee referred to in Article 22(1) of Directive (EU) 2020/2184, |

HAS ADOPTED THIS DECISION:

Section 2. Comprehensive acceptance methodology

Part 1.   Introduction

|  |  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- | --- |
|  | 1.1. | The acceptance methodology for starting substances, compositions and constituents shall be based on a risk assessment. Such risk assessment shall result in:  |  |  | | --- | --- | | (a) | determining the maximum tolerable concentration at tap water (MTCtap) for each relevant chemical species; |  |  |  | | --- | --- | | (b) | ensuring that Ctap for each relevant chemical species is lower than its MTCtap. | |

|  |  |  |
| --- | --- | --- |
|  | 1.2. | In addition to the information required under Annexes I, II and III, a risk assessment shall take into account any other relevant technical or scientific information which is available addressing worst foreseeable conditions of use. Where appropriate, conditions of use shall be implemented. |

|  |  |  |
| --- | --- | --- |
|  | 1.3. | The information provided in the risk assessment shall allow the Committee for Risk Assessment of ECHA to evaluate and reach an opinion on whether the starting substance, composition or constituent complies with the criteria set out under Article 11(1) of Directive (EU) 2020/2184. |

Part 2.   Hazard assessment

|  |  |  |
| --- | --- | --- |
|  | 2.1. | Principles |

|  |  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- | --- |
|  | 2.1.1. | For accepting a starting substance, composition or constituent, the hazard assessment process, in relation to human health shall entail assessment of effects, comprising the following steps:  |  |  | | --- | --- | | (a) | hazard identification: identification of the adverse effects which the relevant chemical species have an inherent capacity to cause; |  |  |  | | --- | --- | | (b) | hazard characterisation: dose (concentration) – response (effects) assessment: estimation of the relationship between dose, or level of exposure to the relevant chemical species, and the incidence and severity of an effect, where appropriate. | |

|  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
|  | 2.1.2. | The hazard assessment for human health shall address the following potential toxic effects for the general human population and exposure by the oral route:  |  |  | | --- | --- | | (a) | mutagenicity; |  |  |  | | --- | --- | | (b) | systemic (target-organ) toxicity after repeated dose administration; |  |  |  | | --- | --- | | (c) | toxicity for reproduction; |  |  |  | | --- | --- | | (d) | carcinogenicity; |  |  |  | | --- | --- | | (e) | neurotoxicity; |  |  |  | | --- | --- | | (f) | immunotoxicity; |  |  |  | | --- | --- | | (g) | endocrine disruption for human health. | |

|  |  |  |
| --- | --- | --- |
|  | 2.1.3. | The hazard identification shall address the properties and potential adverse effects of the relevant chemical species that migrate from the material. |

|  |  |  |
| --- | --- | --- |
|  | 2.2. | Dose-response assessment |

|  |  |  |
| --- | --- | --- |
|  | 2.2.1. | The establishment of a quantitative dose (concentration)-response (effect) relationship is required and, where possible, a no observed adverse effect level (NOAEL) shall be identified. If it is not possible to identify a NOAEL, the lowest observed adverse effect level (LOAEL) shall be identified. Where appropriate, other dose-effect descriptors may be used as reference values. |

|  |  |  |
| --- | --- | --- |
|  | 2.2.2. | When carrying out the hazard assessment, special consideration shall be given to toxicity data derived from observations of human exposure where such data are available, e.g. information gained from manufacture, from poison centres or epidemiology surveys. |

|  |  |  |
| --- | --- | --- |
|  | 2.3. | Derived no effect level |

|  |  |  |
| --- | --- | --- |
|  | 2.3.1. | The derivation of a derived no effect level (DNEL) shall be carried out in accordance with Section 1.4 of Annex I to Regulation (EC) No 1907/2006. |

|  |  |  |
| --- | --- | --- |
|  | 2.4. | Maximum Tolerable Concentration at the tap (MTCtap) |

|  |  |  |
| --- | --- | --- |
|  | 2.4.1. | Subject to Part 2.4.2, the MTCtap is equal to a value calculated on the basis of the safe oral dose (DNEL), the body weight (60 kg), the drinking water ingestion rate of 2 l (litres) per day and an appropriate ALF (expressed as a percentage) to take into account multiple routes of exposure to the relevant chemical species, besides exposure via material used in products in contact with water intended for human consumption. MTCtap (μg/l) =  Formula  Formula |

|  |  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- | --- |
|  | 2.4.2. | By way of exception to Part 2.4.1:  |  |  | | --- | --- | | (a) | If the Ctap < 2,5 μg/l and genotoxicity tests are negative: MTCtap shall (1) not be lower than 0,1 μg/l for an organic cementitious constituent; and (2) not be higher than 2,5 μg/l, unless duly justified and the application fulfils the requirements of Table 2 of Annex V, in which case point (b) below applies. |  |  |  | | --- | --- | | (b) | If the Ctap is equal or above 2,5 μg/l but below 250 μg/l, the MTCtap shall not be higher than 250 μg/l. | |

Part 3.   Migration assessment

|  |  |  |
| --- | --- | --- |
|  | 3.1. | The Ctap to be compared against the MTCtap value shall be determined based on the worst foreseeable conditions of use, including in terms of representativeness of the concentration in the material matrix, water, surface area to water volume, and temperature, as determined by ECHA and published on its website for each test method taking into account, in particular, the requirements for determination based on the worst foreseeable conditions of use and the appropriate EN standard. |

Part 4.   Risk acceptance

|  |  |  |
| --- | --- | --- |
|  | 4.1. | Risk acceptance for starting substances for organic materials, organic cementitious constituents and compositions for enamels, ceramic and other inorganic materials  The starting substance, composition or constituent shall be accepted if Ctap < MTCtap for each relevant chemical species on the 10th day of testing according to point 5.2 in Table 1 of Annex IV. |

|  |  |  |  |  |  |  |
| --- | --- | --- | --- | --- | --- | --- |
|  | 4.2. | Risk acceptance for metallic materials  For the assessment of the test rig results (according to standard EN 15664-1) the arithmetic mean of the equivalent pipe concentrations MEPn(T) analysed from relevant contact waters (see Annex IV, Section 1.1) shall be considered.  The composition can be accepted for a product group with the assumed contact surface a (see Table 2 of Annex II), if the following criteria are met for all required test waters:   |  |  | | --- | --- | | (a) | MTCtap values are met for all analysed elements starting week 16 of testing; |  |  |  | | --- | --- | | (b) | Analysed metal concentrations are not showing increasing trend. | |
