HSE has published a rolling action plan (RAP) of substances to be evaluated. Substance evaluation under UK REACH aims to clarify concerns that the manufacture and/or use of these substances could pose a risk to human health or the environment. In line with our obligations under Article 44 of UK REACH and as stated within the 2022-2023 work programme, HSE has published aRAP of substances which will be evaluated. HSE has one year from the date of publication of the RAP to evaluate substance(s) added to the RAP that year and, where necessary, to prepare a draft decision requesting further information from the registrants to clarify the identified concern. In 2023-2024 HSE, working with the Environment Agency, will evaluate one substance: As part of this process HSE has worked with the Appropriate Authorities to develop and agree criteria for prioritising substances for substance evaluation. These criteria have been published on the HSE website. They will be used to prioritise substances for evaluation in subsequent years. |
