Environment Agency replaces CLR11 (June 2019)

The Environment Agency has recently published an update to the 2004 Model Procedures for the Management of Contaminated Land (CLR11), that was the bible for the investigation and remediation of contaminated sites since 2004. CLR11 was also used in Ireland in a similar fashion to that in the UK. 

The new update is known as Land Contamination: Risk Management (LCRM). Whilst the scope, purpose and framework of CLR11 remains largely the same, LCRM brings it up to date in a more accessible format.  All practitioners dealing in contaminated land should become familiar with the new guidance.   CLR11 will be shelved in six months.

The original CLR11 guidance was a technical framework for applying a risk management process in dealing with sites affected by contamination.  In broad terms, it set out a model of identifying, making decisions on, and taking appropriate and measured action to deal the issue in a consistent way that is in line with current policies, standards and legislation.

CLR11 had three parts:

  • Procedures – The Risk Management Process
  • Supporting Information – Technical Detail to Support the Process
  • Information Map – Sources of Further Information.

This provided a hierarchy of information to assist stakeholders involved in dealing with contamination including landowners, developers, professional advisors, regulatory bodies and finance providers.

LCRM is designed to be a more user-friendly both for experienced practitioners and first-time users. It sets out what types of reports are required, and the information that should be included.  It also references some external industry guidance such as the LQM/CIEH S4ULs (for assessing human health risks), and also the CL:AIRE WALL (Water and Land Library).  In addition, there are links to relevant standards such as BS5930 and the CIRIA guidance.

It is important to note that LCRM requires that a Suitably Qualified Professional (SQP) must produce the relevant reports.  An SQP must for example

  • Have a recognised relevant qualification
  • Have sufficient experience with risk management and the type of contamination you’re dealing with
  • Be a member of a relevant professional organisation
