How to assess if there's unacceptable risk, decide which options are the most suitable to manage the risk and implement remediation if needed.
This guidance is based on the Model procedures for the management of land contamination - contaminated land report (CLR11). The scope, framework and purpose remain the same.
The Environment Agency asked for feedback for 6 months in June 2019. We thank everyone who responded.
We are currently looking at the feedback and will republish in early 2020. We will withdraw CLR11 when this updated guidance is published.
To find more information see the CL:AIRE news item.
