CL:AIRE has produced a new Guidance Bulletin (GB3) which is freely available to download. This bulletin provides a non-technical summary of the DoW CoP.
DoW CoP Guidance Documents
The Definition of Waste: Development Industry Code of Practice (DoW CoP) sets out good practice for industry to follow in the management of excavated materials. It describes an auditable system to demonstrate that the DoW CoP has been applied correctly. CL:AIRE introduced the auditing of projects applying the DoW CoP in 2019 to support its commitment to maintaining and improving industry standards.This work comprises 3 types of audits:
To provide users of the DoW CoP with more transparency and an understanding of what to expect when selected for audit, the following pages provide a summary of the auditing procedures followed by CL:AIRE.

CL:AIRE aims to help QPs understand what the rules and procedures are for the Definition of Waste: Development Industry Code of Practice (DoW COP) and how they are to be used to manage disciplinary and grievance situations which may arise.
Fairness and transparency must always be promoted through clear, specific rules and procedures.
Where formal action is needed, it must be reasonable, fair and justified depending on the circumstances.
This will be achieved by considering the following:

In the usage of this Procedure:
Complainant means any person or persons who have made a written allegation of improper conduct (for example see section 6) against a QP.
Respondent means the QP against whom a written allegation of improper conduct has been made to CL:AIRE.
The Chair is the Chair of CL:AIRE.
An Investigation Panel is a panel which may comprise a member of the CL:AIRE Executive or Board and a representative (or nominated representative) of the Environment Agency (EA) or Natural Resources Wales (NRW), depending on the geographical location, that is appointed to decide whether or not there are grounds for a detailed examination of a specific allegation made by the Complainant against a QP. As such all members of the panel will have significant experience of use or management of the DoW CoP.
A Disciplinary Panel is a panel comprising not less than one representative of the CL:AIRE Executive, one independent representative QP, and may also include one representative of the EA / NRW which is convened for the purpose of a Disciplinary Meeting. Disciplinary panel members will not have acted on the Investigation Panel.
A Disciplinary Meeting is a hearing organised by the Disciplinary Panel, at which the Complainant and Respondent are invited to present their case.
Review meeting is a meeting which may be held in advance of a “Disciplinary Meeting” with the Qualified Person to help establish the facts of any complaint.
Appeal Panel acts in the event of an appeal to the decision of the Disciplinary Panel and can uphold or overturn or vary.

A complaint that a QP has behaved contrary to the expected manner required by the DoW CoP, must be submitted in writing to CL:AIRE outlining the details. Such a complaint can be made by any individual or organisation.
Complaints will be reviewed by the Investigation Panel, which may –
In coming to its decision, the Investigation Panel may call for submissions from either the Complainant or the QP or both.
It is important to carry out necessary reviews of disciplinary matters without unreasonable delay when establishing the facts of the situation. In some cases this will require holding a review meeting with the QP before proceeding to any disciplinary meeting. In others, the review stage will be the collation of evidence by CL:AIRE for use at any disciplinary meeting.
If it is decided that there is a disciplinary case to answer, the QP should be notified of this in writing. This notification will contain information about the alleged misconduct or poor performance to enable the QP to prepare to answer the case at a disciplinary meeting.
The Respondent and the Complainant shall be notified of the process by which the allegations are to be dealt with.
The Respondent shall be given 21 working days from the date by which CL:AIRE informs of the details of the allegations made by the Complainant, to respond in writing to the allegations (including submitting evidence).
Meetings will be held without unreasonable delay whilst allowing the QP adequate time to prepare their response. CL:AIRE shall give 21 working days notice of a disciplinary meeting. The notice shall be issued in writing and shall outline the allegations. Reasonable steps will be taken to agree a convenient date, time and location for the meeting and arrange any special needs of the attendees (online meeting facilities may be used if most convenient for all parties).
The following steps will be taken prior to a disciplinary panel meeting:-
The QP will make every effort to attend the meeting, at which CL:AIRE will explain the complaint against the QP and go through the evidence that has been gathered. The QP will be allowed to set out their case and answer any allegations that have been made. The QP will be given a reasonable opportunity to ask questions and present evidence or witnesses.
The QP has the right to be accompanied by no more than one representative or advisor. They must be agreed in advance of the meeting with CL:AIRE for practical purposes e.g. venue size, accessibility. A request to be accompanied should provide enough time for CL:AIRE to make the necessary arrangements with regards venue size and facilities for the companion’s attendance at the meeting.
The companion should be allowed to address the meeting, to put and sum up the QP’s case, respond on behalf of the QP to any views expressed at the meeting and confer with the QP during the meeting. The companion does not, however, have the right to answer questions on the QP’s behalf, address the meeting if the QP does not wish it or prevent CL:AIRE from explaining their case.
The QP may submit supplementary evidence to the disciplinary meeting. This must be received by the Disciplinary Panel not less than 5 working days before the date set for the meeting.
The Disciplinary Panel will determine the procedure to be followed in the presentation of the documentation prior to, during, and in the conduct of the meeting. The decision of the Disciplinary Panel will be final in such matters in determining the conduct of the meeting which shall be in accord with natural justice.
The Disciplinary Panel shall consider the case, may call for independent technical advice, and shall determine whether the complaint against the Respondent has been made out or not.
The Panel may reach a decision in absentia if a Respondent refuses to attend the meeting.
After the meeting, the Disciplinary Panel will decide whether or not disciplinary or any other action is justified and inform the QP accordingly in writing.
If the finding is that the complaint has been made out, the Panel may:
Where misconduct is confirmed, or the QP is found to be performing unsatisfactorily, it is usual to give the QP a written warning. A further act of misconduct or failure to improve performance within a set period would normally result in a final written warning.
A first or final written warning should set out the nature of the misconduct or poor performance and the change in behaviour or improvement in performance required (with timescale). The QP should be told how long the warning will remain current.
The QP should be informed of the consequences of further misconduct, or failure to improve performance, within the set period following a final warning. For instance that it may result in dismissal from the QP register.
If a QPs first misconduct or unsatisfactory performance is sufficiently serious (termed gross misconduct), it may be appropriate to move directly to a dismissal from the QP Register without notice for a first offence. This might occur where the QP’s actions have had, or are liable to have, a serious or harmful impact on the DoW CoP.
A decision to dismiss from the QP register should be taken by the CL:AIRE Board of Trustees. The QP should be informed as soon as possible of the reasons for the dismissal, the date on which their QP status will end, and the appropriate period of notice.
Upon removing a QP from the Register, CL:AIRE will also notify their Professional Institute of this action and their employer.

The Qualified Person has the right to appeal on the following grounds:
Any appeal shall be made in writing to the CL:AIRE Executive, setting out the grounds, to be received within 21 working days of the date of notification of the decision of the Disciplinary Panel. An appeal shall include any new evidence if this ground is relied upon.
Upon receipt of an appeal, the Executive shall appoint an Appeal Panel to consist of three appropriate persons who may not include any person who was a member of the Investigation Panel or Disciplinary Panel sitting for the case in question (for example members of the CL:AIRE Technology & Research Group, Trustees, legal advisor).
The Appeal Panel shall consider the appeal and shall determine whether the decisions of the Disciplinary Panel should stand in whole or part or not. Generally the Appeal Panel will deal with matter based on written representations by the appellant.
The decision of the Appeal Panel, which may be taken by simple majority, shall be binding and shall be communicated to the CL:AIRE Executive. Such a decision may be to uphold or overturn or vary; the decision and/or sanction of the Disciplinary Panel and shall be final.
The CL:AIRE Executive shall inform the Respondent and the Complainant in writing of the decision of the Appeal Panel.

The proceedings of the Investigation Panel, Disciplinary Panel and Appeals Panel shall remain confidential to the CL:AIRE Executive and members of the panels and shall not be disclosed to third parties, other than to the Respondent and Complainant, their representatives and regulators (EA / NRW).
Where the final decision results in the complaint being upheld and removal of the QP permanently from the Register, the outcome may be made public on the CL:AIRE website. Furthermore, the QPs Professional Institute and employer will also be notified of the decision.
Where a complaint is found not to be upheld, the proceedings and outcome will not be made public unless the Respondent specifically requests this.
If the Respondent tenders their resignation as a QP from the Register during the main or appeals procedure, the process will be continued to a conclusion. If the complaint is upheld, the result may be made public on the CL:AIRE website and the QPs Professional Institute and employer will also be notified of the decision.


CL:AIRE aims to help Project Teams understand what the rules and procedures are for the CL:AIRE Definition of Waste: Development Industry Code of Practice (DoW CoP) and how they are to be used to manage disciplinary and grievance situations which may arise, either during or after a project.
Fairness and transparency must be promoted through clear, specific rules and procedures.
Where formal action is needed, it must be reasonable, fair and justified depending on the circumstances.
This will be achieved by consideration of the following:
In the usage of this Disciplinary & Grievance Procedure:
A complaint that a Project Team has behaved contrary to the expected manner required by the DoW CoP, must be submitted in writing to CL:AIRE outlining the details. Such a complaint can be made by any individual or organisation and this procedure will be followed to its conclusion.
Complaints will be reviewed by the Investigation Panel, which may –
In coming to its decision, the Investigation Panel may call for submissions from either the Complainant or the Project Team / Organisation or both.
It is important to carry out necessary reviews of disciplinary matters without unreasonable delay when establishing the facts of the situation. In some cases this will require holding a Review Meeting with the Project Team before proceeding to any disciplinary meeting. In others, the review stage will be the collation of evidence by CL:AIRE for use at any Disciplinary Meeting.
If it is decided that there is a disciplinary case to answer, the Project Team should be notified of this in writing as soon as practicable. This notification will contain information about the alleged misconduct or poor performance to enable the Project Team to prepare to answer the case at a disciplinary meeting.
The Respondent and the Complainant shall be notified of the process by which the allegations are to be dealt with.
The Respondent shall be given 21 working days from the date by which CL:AIRE informs of the details of the allegations made by the Complainant, to respond in writing to the allegations (including submitting evidence). No response will automatically trigger the need for a Disciplinary Meeting.
Meetings will be held without unreasonable delay whilst allowing the Project Team adequate time to prepare their response. CL:AIRE shall give 21 days notice of a Disciplinary Meeting. The notice shall be issued in writing and shall outline the allegations. Reasonable steps will be taken to agree a convenient date, time and location for the meeting and arrange any special needs of the required attendees (online meeting facilities may be used if most convenient for all parties).
The following steps will be taken prior to a disciplinary panel meeting:-
The Project Team will make every effort to attend the meeting, at which CL:AIRE will explain the complaint against them and present the evidence that has been gathered. The Project Team will be allowed to set out their case and answer any allegations that have been made. The Project Team will be given a reasonable opportunity to ask questions and present evidence or witnesses.

The companion does not, however, have the right to answer questions on behalf of the Project Teams, nor address the meeting if the Project Team does not wish it or prevent CL:AIRE from explaining their case.
The Project Team may submit supplementary evidence to the Disciplinary Meeting. This must be received by the Disciplinary Panel not less than 5 working days before the date set for the meeting.
The Disciplinary Panel will determine the procedure to be followed in the presentation of the documentation prior to, during, and in the conduct of the meeting. The decision of the Disciplinary Panel will be final in such matters in determining the conduct of the meeting which shall be in accord with natural justice.
The Disciplinary Panel shall consider the case, may call for independent technical advice, and shall determine whether the complaint against the Respondent has been made out or not.
The Panel may reach a decision in absentia if a Respondent refuses to attend the meeting.
After the meeting, the Disciplinary Panel will decide whether or not disciplinary or any other action is justified and inform the Project Team accordingly in writing.
If the finding is that the complaint has been made out, the Panel may:
Where misconduct is confirmed, or the Project Team is found to be performing unsatisfactorily, it is usual to give them a written warning and inform the relevant regulator. A further act of misconduct or failure to improve performance within a set period would normally result in a final written warning.
A first or final written warning should set out the nature of the misconduct or poor performance and the change in behaviour or improvement in performance required (with timescale). The Project Team shall be told how long the warning will remain current.
The Project Team shall be informed of the consequences of further misconduct, or failure to improve performance, within the set period following a final warning. For instance that it may result in restriction of future use of the DoW CoP.
If a Project Teams first misconduct or unsatisfactory performance is sufficiently serious (termed gross misconduct), it may be appropriate to move directly to restriction of future use of the DoW CoP without notice for a first offence. This might occur where the Project Teams actions have had, or are liable to have, a serious or harmful impact on the DoW CoP.
A decision to restrict future use of the DoW CoP should be taken by the CL:AIRE Board of Trustees. The Project Team be informed as soon as possible of the reasons for the dismissal, the date on which their use of the DoW CoP will end, and the appropriate period of notice. The restriction will apply to the organisation(s) in question, not individuals e.g. should individuals move to a different organisation not involved, the restriction will not apply to them.
The Respondent has the right to appeal on the following grounds:
Any appeal shall be made in writing to the CL:AIRE Executive, setting out the grounds, to be received within 21 days of the date of notification of the decision of the Disciplinary Panel. An appeal shall include any new evidence if this ground is relied upon.
Upon receipt of an appeal, the CL:AIRE Executive shall appoint an Appeal Panel to consist of three appropriate persons (for example members of the CL:AIRE Technology & Research Group, Trustees, legal advisor) who may not include any person who was a member of the Investigation Panel or Disciplinary Panel sitting for the case in question.

The CL:AIRE Executive shall inform the Respondent and the Complainant in writing of the decision of the Appeal Panel.
The proceedings of the Investigation Panel, Disciplinary Panel and Appeals Panel shall remain confidential to the CL:AIRE Executive and members of the Panels and shall not be disclosed to third parties, other than to the Respondent and Complainant, their representatives and regulators (EA / NRW) who may notify HMRC.
Where the final decision results in the complaint being upheld and restriction of future use of the DoW CoP, the outcome may be made public on the CL:AIRE website.
Where a complaint is found not to be upheld, the proceedings and outcome will not be made public unless the Respondent specifically requests this.

The DoW CoP (launched in September 2008) has significantly increased the sustainability of land remediation and development projects.
It has become a common approach for the management of excavated materials on development sites.
The DoW CoP enables the direct transfer and reuse of clean naturally occurring soil materials between sites.
It supports the establishment and operation of fixed soil treatment facilities and it enables the reuse of both contaminated and uncontaminated materials on their site of origin, and between sites within defined Cluster projects.
