Environmental due diligence is considered legal or environmental necessity during property development, rezoning, and the acquisition of land in New South Wales. Two primary steps are known as the Preliminary Site Investigation NSW and Detailed Site Investigation NSW, which identify any potential contamination hazards and the suitability of a site for its intended use. We will look into what can happen during such investigations and why they matter.
What is Preliminary Site Investigation (PSI) in NSW?
It aims at identifying potential or known sources of contamination that may arise from the historical and current site uses. A PSI consists of:
● A desk-based review of pertinent previous reports and records maintained by governmental authorities and aerial imagery
● Identifying potential contaminants of concern (i.e., chemicals, fuel, heavy metals)
The goal of a PSI is to assess the likelihood of some form of contamination being present that would constitute a potential risk for further investigation. If there are no significant risks apparently evidenced from the investigation, the PSI may just be adequate to support planning approvals.
What does any Detailed Site Investigation (DSI mean for NSW)?
Whereas the PSI detects contamination risks, the Detailed Site Investigation NSW is to be conducted. This stage involves a more intensive level of study that includes sampling and laboratory testing of soil, groundwater, and surface water. In summary, here are the key components found in DSI include:
● Developing sampling and analysis quality plan (saqp)
● On-the-spot drilling and sample collection
● Laboratory contaminant testing
● Comparison of results to national environmental standards
● Human health risk assessment and ecological impact
No less is then required to be known by the remediation requirement or whether or not the site could then be used appropriately for its intended purpose.
Why Are These Investigations Important?
PSI and DSI contribute an essential aspect of responsible land management in NSW. Good management will ensure best practice for planning compliance, human health protection for future occupants, and reduced legal and financial liabilities for developers. Not only that, but these investigations also fit perfectly into the NSW Environment Protection Authority (EPA) guidelines, ensuring your project progress in a smooth and sustainable way.
Conclusion
Final investigative propaganda for you- Besides buying lands or redeveloping a site or simply applying for planning approval, a Preliminary Site Investigation NSW, along with Detailed Site Investigation NSW, if required, is the need of the hour. With this process, the environment and public health are protected, and, obviously, you are assured of building on a safe, compliant foundation in your endeavor.
