Regulatory management option analysis (RMOA) and Technical Reports (TRs)
Regulatory management option analysis (RMOAs) and technical reports (TRs) are not legal requirements but are both key tools to support HSE (as the Agency for UK REACH) and Appropriate Authorities in their regulatory work.
As part of both RMOAs and TRs, stakeholders, including other government departments and agencies, may be invited to contribute to the process by submitting information or through direct engagement with the Agency. Information can be provided by responding to a call for evidence, where available, or by contacting the REACH team in HSE directly.
This page provides information about ongoing and completed RMOAs and TRs.
RMOAs and TRs that have been completed will be published on this page.
Regulatory management option analysis
An RMOA is a technical dossier that provides an assessment of potential health and environmental risks associated with the use of a substance or group of substances, a description of the existing regulatory framework and specific controls relating to them.
Where the Agency considers existing regulatory controls may be insufficient, the RMOA will identify options to resolve this concern. This could include further regulatory measures but might also include voluntary actions that stakeholders could initiate.
An RMOA does not replace the statutory regulatory processes that the REACH regulation requires to identify a substance as a Substance of Very High Concern (SVHC), add a substance to the Annex 14 Authorisation List or propose a restriction. However, it will provide information about the reasons why these, or other, regulatory actions are being initiated.
The RMOA will also outline the reasons why no regulatory action is being initiated if this is the most appropriate approach.
HSE with support from the Environment Agency, will:
- complete RMOAs to describe the reasons why regulatory action is being considered
- document the existing regulatory landscape around the concern
- identify which regulatory action or actions might be needed to resolve concerns
- highlight any key areas of uncertainty in the available information.
Recommendations for regulatory action from RMOAs will have been shared with the Appropriate Authorities and relevant other government departments, to agree any future action.

Technical Reports
TRs summarise the scientific evidence around the hazard, exposure, use and risk information for substances chosen for review under UK REACH. TRs do not identify any regulatory action/s that might be needed to resolve concerns if these are identified.
TRs will be used to help inform on the regulatory needs for certain substances and for prioritisation. The Agency will inform the Appropriate Authorities and relevant other government departments of the publication of TRs.
