CL:AIRE Materials Management Plan

Need a CL:AIRE Materials Management Plan?

Don't pay landfill tax on clean soil. If you are a developer or earthworks contractor planning to reuse excavated materials on or off-site, a CL:AIRE Materials Management Plan (MMP) is essential to remain legally compliant and highly cost-effective. SWEL can fully draft your MMP and arrange your Qualified Person (QP) to sign off your earthworks strategy. Need a quote for your project?

• Phase 1 Desktop Studies (Contaminated Land)
• Phase 2 Intrusive Site Investigations (Soil Sampling)

What is a CL:AIRE Materials Management Plan?

The CL:AIRE Materials Management Plan (MMP) is a document that is used to demonstrate that excavated materials can be reused without being classified as waste. It is a requirement of the CL:AIRE Definition of Waste Code of Practice, which is used in England and Wales.

The CL:AIRE MMP must include the following information:

• The type and quantity of materials to be reused
• The proposed use of the materials
• The assessment of the suitability of the materials for reuse
• The measures that will be taken to protect human health and the environment
• The certainty of use of the materials

Who Prepares a CL:AIRE Materials Management Plan?

The CL:AIRE MMP must be prepared by a qualified person and must be submitted to the Environment Agency before the materials can be reused.

The CL:AIRE MMP is a valuable tool that can help to reduce the amount of waste produced from construction projects. It can also help to save money and protect the environment.

Here are some of the benefits of using a CL:AIRE MMP:

• It can help to reduce the amount of waste produced from construction projects.
• It can help to save money by avoiding the cost of waste disposal.
• It can help to protect the environment by reducing the amount of waste that is sent to landfill.
• It can help to improve the sustainability of construction projects.

If you are involved in a construction project in England or Wales, you should consider using a CL:AIRE MMP. It is a valuable tool that can help you to reduce waste, save money, and protect the environment.

What Information is Required in a Materials Management Plan?

Here are some of the things to consider when creating a CL:AIRE MMP:

• The type and quantity of materials to be reused
• The proposed use of the materials
• The assessment of the suitability of the materials for reuse
• The measures that will be taken to protect human health and the environment
• The certainty of use of the materials

You can find more information about the CL:AIRE Materials Management Plan on the CL:AIRE website.

Materials Management Plan - Scenarios

There are 4 scenarios considered in an MMP, number 2 being the most common.

1. Reuse on the Site of Origin
2. Direct Transfer of clean naturally occurring soil / mineral materials
3. Cluster Project
4. Combination of any of the above

Materials Management Plan - Desktop Study

You will be required to attach copies or relevant extracts from the Desktop Study that demonstrate that there is no suspicion of contamination.

Sustainable Soil Reuse: CL:AIRE Materials Management Plans (MMP)

The CL:AIRE Definition of Waste Code of Practice (DoW CoP) provides a streamlined, professional framework for the reuse of excavated materials on development sites. By implementing a robust Materials Management Plan (MMP), developers can avoid the complexities of environmental permitting and waste exemptions while ensuring full regulatory compliance.

The Benefits of an MMP for Your Project

Utilizing an MMP is not just about compliance; it is a critical tool for site efficiency and sustainability.

• Cost Reduction: Avoid significant landfill tax and haulage costs by keeping suitable materials on-site.
• Sustainability: Support circular economy principles by minimizing the need for imported primary aggregates.
• Regulatory Clarity: A Qualified Person (QP) declaration provides the Environment Agency with the necessary assurance that materials are not being "discarded" as waste.

Our Technical Approach

Southwest Environmental Limited provides a comprehensive service to navigate the DoW CoP process.

• MMP Preparation: We draft detailed plans that define the "Origin" and "Destination" of materials, supported by a clear Remediation Strategy or Design Statement.
• Chemical Suitability: We conduct rigorous testing to ensure materials meet the required site-specific assessment criteria (SSAC) and do not pose a risk to human health or the environment.
• Qualified Person (QP) Review: Our independent QPs review the documentation and submit the required declaration to CL:AIRE.
• Verification Reporting: Upon completion, we provide the essential CL:AIRE Verification Report to close the audit trail.
