|Creiterion||Assessment Criteria||Applicable Answer|
|1.||An assessment of the risks from potential land contamination associated with the asset’s site has been performed by a contaminated land professional or conducted under the supervision of a contaminated land professional within the last 5 years.||C-E|
The assessment comprises review or compilation of the following as appropriate to the site’s condition:
Where any of the above tasks have previously been performed, e.g. as part of the construction of the asset or through environmental due diligence work, this information may be used to demonstrate compliance with this assessment issue. Where this information is older than 5 years, a contaminated land professional must review the status of the information and confirm that the assessment is still valid.
|-||The evidence below is not exhaustive, please also refer to the ‘BREEAM evidential requirements’ section in the scope of the Guidance for appropriate evidence types which can be used to demonstrate compliance.|
|All||Report(s) from contaminated land professional(s).|
|All||Written confirmation from the asset or site owner that further intrusive investigation and/or remedial works have been planned.|
Contaminated land professional:
An individual that holds a degree or equivalent qualification in chemistry, environmental science or management, earth sciences, civil engineering, or a related subject, and has a minimum of three years relevant experience (within the last five years) in site investigation, risk assessment and appraisal. Such experience must clearly demonstrate a practical knowledge of site investigation methodologies and understanding of remediation techniques and national legislation on the subject; as well as acting in an advisory capacity to provide recommendations for remediation.
Any substance or agent in or on the ground, which presents an unacceptable risk to human health, property or the environment.
Any activity undertaken to prevent, minimise, remedy or mitigate the risk to human health, property or the environment caused by land contamination.
Land contamination is usually caused by previous industrial uses on or within the vicinity of a site but may also be present due to spills or leaks from current or recent activities on or near the site. However, it cannot be ruled out in other locations including in rural areas (e.g. by inappropriate spreading of materials such as sludge, or as a result of contamination being moved from its original source). In addition, some areas may be affected by the natural or background occurrence of potentially hazardous substances, such as radon, methane or elevated concentrations of metallic elements.
