Remediation is the third stage of a phased contaminated land assessment that is often required to discharge planning conditions to ensure safe development. Remediation is typically required following submission and approval of a Phase 2 Site Investigation, and is designed to break the pollutant linkages identified or appropriately reduce the associated risks of pollution to an acceptable level.
The first and possibly most fundamental part of remediation is the preparation of a Remediation Strategy (also known as a Remediation Plan). The Remediation Strategy identifies the most suitable remedial option for the site.
Lustre Consulting considers this to be a vital part of the process, which ensures that both the client and relevant regulators agree on a methodology at an early stage, providing a more efficient and cost effective solution. The chosen remedial option will depend on a number of factors including the nature of contamination, proposed development, geology, access, timescales and budget. The Remediation Strategy allows each factor to be assessed in turn to ensure that the most suitable remedial option has been chosen.
When complete, the Remediation Strategy is submitted to the local planning authority and any other relevant regulators (such as the Environment Agency) for approval prior to commencing with the works.
There are a range of remediation techniques available; constantly evolving as the industry advances. As an environmental consultancy it is vital to have a sound knowledge of all available options and remain up to date with new technologies within the industry. Common examples include:
Engineered capping layer.
Localised hotspot removal.
Stabilisation and solidification.
Bioremediation (windrows, biopiles, insitu bioremediation).
Pump and treat.
At Lustre Consulting we pride ourselves on designing cost effective and compliant remediation schemes that effectively target identified sources of contamination.
To meet your requirements and ensure you remain compliant, all our Remediation Strategies are prepared by qualified and competent consultants in accordance with current guidance such as the recommended approach set out in the Environment Agency’s Model Procedures for the Management of Land Contamination (CLR11).
Some important points to consider when commissioning a Remediation Strategy:
Do you have any planning conditions attached to your planning permission? Or is the purpose of the Remediation Strategy to minimise potential environmental liabilities that may be associated with the site?
Are there any access constraints that may restrict the use of some of the remediation methods described above? Is the site operational or vacant?
In terms of timescales, this will depend on the type of remediation employed, the nature of the ground conditions and extent of contamination. Is it possible to carry out remediation as part of the site enabling works?
