CL:AIRE Code of Practice Declarations

CL:AIRE Code of Practice Declarations

As regulators, we need to ensure measures are in place to protect the environment and human health.


Our regulatory guidelines support the Contaminated Land: applications in real environments code of practice (CL:AIRE cop), which if followed properly mean that under certain circumstances materials arising on site need not be considered waste.

The CLAIRE Code of Practice (CoP) is a voluntary framework for determining whether or not excavated material arising from site during remediation and/or land development works are waste. The CoP applies to excavated materials that are:

  • reused on the site of production;
  • transferred between sites and reused directly without treatment: or
  • transferred between sites and reused following treatment, as part of a Cluster project

Since the 1st April 2013 Natural Resources Wales has become the responsible body in Wales for developers in Wales to send their CL:AIRE Code Of Practice declarations to. They should be sent to the following address:

Via Email: permitreceiptcentre@naturalresourceswales.gov.uk

Via Mail:
Permit Receipt Centre,
Natural Resources Wales,
Ty Cambria
Cardiff
CF24 0TP

For an interim period Natural Resources Wales is continuing to use and follow the Environment Agency’s guidance.
