Whether the Court can be satisfied that the land will be remediated before the land is used for the purpose for the development is proposed to be carried out
According to Mr Norris, a Remedial Action Plan (RAP) prepared by Martens Consulting Engineers and dated July 2021 (Ex A, tab 24) was prepared to detail how the site is to be made suitable for the proposal. The RAP is based on the findings of the Detailed Site Investigation (DSI). The DSI identifies six phases of investigation comprising 226 test pits, 52 bore holes and six groundwater monitoring wells (Muscat Developments Pty Ltd v Wollondilly Shire Council [2021] NSWLEC 1738 at [120]). The DSI concludes that areas of the site, including the proposed location of the development, are contaminated with asbestos contaminated fill material (Ex A, tab 24, p 15). The RAP, in summary, proposes encapsulation of contaminated material beneath an appropriately designed capping layer and development of a long-term Environmental Management Plan (LTEMP).
The RAP proposes to excavate approximately 1,200m3 of material in Remediation Area 1, and to cap the material in Remediation Area 2 (Muscat Developments Pty Ltd v Wollondilly Shire Council [2021] NSWLEC 1738 at 145]). The RAP was the subject of a site audit prepared by an accredited site auditor, which resulted in the issue of a Section B Site Audit Statement (SAS) and an associated report (SAR) (Ex G) for the site. The SAS certifies that the site can be made suitable by implementing the RAP and conditions described in the SAS.
The contaminated material at the site, containing asbestos fines/friable asbestos (AF/FA), was notified to the Environment Protection Authority (EPA), by the site auditor on 2 August 2021 under s 60 of the Contaminated Land Management Act 1997 (Ex 4, tab F). Following the receipt of the notification on 25 August 2021, the EPA determined that the contamination at the site does not warrant regulation under the Contamination Land Management Act 1997, because the risk to human health associated with AF/FA contamination outside of the site is considered to be low and acceptable based on the location of the site in a rural area, and the potential exposure to intrusive maintenance works can be managed through appropriate work health and safety procedures (Ex 4, tab D).
Mr Clay has carried out his own testing and assessment to identify the extent of asbestos contamination on the site (Ex 3). Mr Clay is critical of the DSI, the RAP and the SAS.
According to Mr Clay, the SAS is deficient on a number of grounds (Ex 3, p 2). I accept Mr Norris' response regarding those identified deficiencies (Ex 3, pp 5-6). I accept the agreement of the civil engineering experts (Ex 5) that the concept civil engineering plans are adequate and that the Council's contentions regarding engineering are addressed by the proposal and conditions of consent.
According to Mr Clay, the vast majority of the asbestos on the site is a different sort of asbestos than AF/FA, and that contaminated material is not addressed by the EPA in the letter (Ex 4, tab D). In response, Mr Norris said that the EPA was provided with the DSI and the RAP by the site auditor, and so the EPA has not responded in ignorance of the actual contamination on the land, instead, the EPA had all the information necessary to fully consider the contaminated material on the site. In addition, Mr Norris noted that AF/FA is much more hazardous and hence the requirement for notification of AF/FA under the Contaminated Land Management Act 1997. Mr Clay agreed that the risk arising from the non-friable asbestos is much lower than the risk to human health from AF/FA.
According to Mr Norris, the Court can be reasonably satisfied that the land is able to be made suitable for the proposal, on the bases of the RAP and SAS. The conditions of consent impose a requirement that the land is certified as remediated and suitable for the proposal prior to the issue of an occupation certificate, ensuring that the site will be remediated before the land is used for the purpose for which the development is proposed to be carried out.
I accept the parties' agreement that pursuant to cl 4.6(1)(a) of SEPP Resilience and Hazards, the site on which the development is proposed is contaminated and the land requires remediation to be made suitable for the proposal. It is a jurisdictional threshold pursuant to cl 4.6(1)(c) of SEPP Resilience and Hazard that I must be satisfied that the land will be remediated before the land is used for the purpose for which the development is proposed to be carried out.
I accept and prefer Mr Norris' evidence. I am satisfied by the DSI, RAP and SAS supporting the application that the site can be remediated and will be suitable thereafter for use as an equestrian centre with roads. The imposition of conditions F.5 and F.8 on the consent ensures that the site will be remediated to be made suitable for the proposal in accordance with the RAP and the SAS and conditions, and certified as such by a Section A2 SAS, prior to the issue of any occupation certificate.
