This case study reviews the merger of the Environmental Protection Agency (EPA) with the former Radiological Protection Institute of Ireland (RPII), which took place in August 2014. The merger happened within the context of an extensive programme of public service cost reduction and agency rationalisation.

It is recognised that it is too early to reach definitive conclusions with regard to the longer-term outcome of the merger.  However, three years after the event it was considered appropriate to review the merger with the objectives of:

1. documenting the merger process and, in particular, acknowledging the significant work involved;
2. discussing the merger with EPA staff and identifying areas where consolidation is still required; and
3. sharing with other public bodies the considerable learning achieved within the EPA as a result of the merger.
