(a) Different risk allocations are appropriate for High Risk Sites and Low Risk Sites, given their differing degrees of risk. These are detailed in sections 4.4.5 and 4.4.6 below.
(b) High Risk Sites may be identified by reference to any of the following characteristics:
(i) sites which would ordinarily be referred to as brownfield sites;
(ii) previous industrial, heavy commercial or hospital land use likely to give rise to contamination and with existing structures, or other site users, compromising accessibility for due diligence; and
(iii) sites where extensive contamination or latent geotechnical conditions are likely and a full investigative survey is commercially impractical.
(c) Low Risk Sites may be identified by reference to any of the following characteristics:
(i) sites which would ordinarily be referred to as greenfield sites;
(ii) previous land use limited to rural, residential, light commercial or light industrial (e.g. office or warehouse);
(iii) minimal structures on the site;
(iv) long-standing pre-existing reservation for the project; and
(v) accessible for private party due diligence investigation.
