Intervention reports - 2012

Intervention reports are written by our inspectors following visits to the sites we regulate. They are used to record findings and, if appropriate, any significant actions we require the site operator to carry out in order to improve matters.

Publishing executive summaries of these reports is one part of ONR’s aim to be open and transparent by helping all of our stakeholders, including the public, understand our work.
