Stage 3: Remediation Action Plans and Site Management Plans

Once a site has been fully characterised for site contamination, commercial decisions can be made on whether to progress to remediation the next stage of the assessment process. Often a site is developed to increase its value and part of this value is used to remediate the site. Often, to progress from a commercial/industrial use to a residential use, remediation and or management for the site is required to ensure an acceptable risk to site users.

The site characterisation in part outlines the risks to site users associated with the site contamination. Occasionally it will be cost efficient to derive site based criteria or complete a site specific risk assessment in order to reduce the remediation costs. 
Remediation can take on many forms, from on-site bioremediation, green chemistry, phytoremediation, bioavailability reduction, active barriers, pump and treat, on-site disposal or encapsulation and ‘dig and dump’ or off-site disposal.

The key to good remediation strategies is matching the remediation technique to the client’s desired outcome. As well as offering the clients a range of options for their site in order that they can make the correct commercial decision for their circumstances.
A Remediation Action Plan (RAP) is a statutory document that outlines the sites contamination, the suggested pathways for its remediation and the management of the site during the remediation process. 

A RAP can be produced for a site, along with a Site Management Plan (SMP) to manage the contamination. The site can then remain on the Environmental Management Register (EMR) and be sold with the RAP and SMP attached to the site or the client can keep the site and remediate at a more commercially viable later stage.

A remediation strategy is not a statutory document and is used, when the client wishes to remediate a site following characterisation of the site contamination.  Often a client may decide that the best commercial option is to maximise the potential value of a site and progress through all four stages of assessment in one go. This has the added advantage of reducing reporting costs and can lead to savings of mobilisation of contractors and equipment.
