NQMS for Land Contamination Management
The National Quality Mark Scheme for Land Contamination Management (NQMS) is developed by the National Brownfield Forum to provide visible identification of documents that have been checked for quality.

CL:AIRE is keeping a register of materials and services which may fall within the Definition of Waste Code of Practice (DoWCoP). We aim to link material holders with service providers or organisations requiring materials in order to make the process of finding project partners an easier and quicker process.

Organisations involved in the management of development sites are urged to register key information on materials and services which fall within the DoWCoP which will be held confidentially by CL:AIRE.  For example - which sites are being or are due to be remediated/developed?  What treatment options are in use or available in an area of the country? Where are there site imbalances of soils or fill materials?

CL:AIRE will review the information provided against the Register and contact organisations where we see possible project partnerships for 'finding homes' for materials.  The information submitted to the Register will be circulated amongst all members on a regular basis; should an entry be of particular interest to a member they should notify CL:AIRE who will act to make the necessary introductions such that further discussions and information transfer can take place. 

CL:AIRE's independence in the market and its familiarity with the DoWCoP positions it perfectly to act as a trusted administrator of such an initiative.

What Information is Required?

Nothing above and beyond what will already exist - site details, information surrounding the materials for example analysis data, information on treatment capabilities or reuse criteria. CL:AIRE will only circulate information which members are willing to distribute; CL:AIRE will not amend any submissions, the information contained on the register remains the responsibility of the submitting organisation for its accuracy.

To add an entry to the Register simply email nick.willenbrock@claire.co.uk - Mark the Subject line as either ROM Donor / ROM Receiver / ROM STF depending on the nature of the site you would like to add. Then in the email body provide the following details -

Donor Site Example

Location - Middlesex

Quantity - 20,000m3

Availability From / To - Nov 2013

Material Type - Soils & stones

Chemical Analysis Available? - Available on request

 

Receiver Site Example

Location - Chippenham

Quantity needed - 40,000 m3

Availability From / To -Late 2011/Early 2012

Material Type - Clay

 

Specified End Use - Clean materials for an engineering fill

Soil Treatment Facility Example

Location - Derby

Yearly Intake - 100,000 m3

Timescale - Immediate

Treatable Material/ContaminantsNotes - Excavated fill / VOCs, PAHs

For clarification, sections 1.10 and 1.11 of the Code of Practice outline clearly which materials are covered by the CoP and which are not. It is the responsibility of the users of the Register to make the decision on whether the CoP applies; CL:AIRE only act to support the linking of possible project partners. Inclusion of materials on the register is not an indication that they are suitable for reuse following the CoP.  For information on the CoP pleaseclick here>>


How Much Does it Cost?

To submit details to the register costs nothing. CL:AIRE as a charity and NGO relies heavily on various organisations for funding and support amongst its many projects and initiatives. We strongly encourage all users of the Register to consider CL:AIRE Membership; money raised from the scheme covers the cost of running the Register. Should CL:AIRE be successful in assisting in developing project partnerships we would request a discussion with project partners upon successful completion to agree a possible financial donation appropriate to the benefits gained by the project.

Who Should Use the Register?

  • Anyone involved in the management of development sites for example site owners, consultants or contractors.
  • Soil Treatment Providers who wish to link their facilities using the Cluster approach.
  • Large development site owners with on site treatment facilities which could form the Hub of the Cluster network.

How Long Will it Take to Find Partnerships?

As CL:AIRE cannot guarantee that sites or materials will be available at any one time or location, an answer cannot be given. The more organisations linking with the scheme however will increase the likelihood of finding possible partnerships as such we encourage as many individuals and organisations to join the scheme as possible.

Who Do We Contact?

If you are interested in any of the sites, please contact Nicholas Willenbrock on +44 (0)​118 228 1488​ or email nick.willenbrock@claire.co.uk.
