iEnvi provided an independent asbestos source assessment and post‑removal clearance at a greenfield development in Catherine Field. The assessment determined the fragment originated from a historic stockpile, verification testing returned no asbestos detected, and the site was cleared to progress with development.
How a targeted investigation, waste classification testing and a pragmatic remediation strategy closed data gaps for asbestos‑contaminated imported fill in north‑west Sydney — turning a NSW EPA Clean‑Up Notice into a compliant, cost‑efficient remediation pathway.
iEnvi expanded its network of independent contaminated‑land sub‑consultants in 2022 to improve local availability, technical depth and delivery flexibility for clients across Australia.
iEnvi provided site sampling, waste classification and VENM assessment for Transport for NSW during Jenolan Caves Road remediation works, enabling compliant reuse and reducing disposal costs while keeping the project on schedule.
Targeted soil assessment of a former oyster farm footprint identified low-risk PAH sources (asphalt fragments) rather than residual coal tar, resolving a data gap and enabling council approval for low-density residential development.
iEnvi completed an in‑situ waste classification and Excavated Natural Material (ENM) assessment for a Southern Highlands council road upgrade. Of 20 samples collected at 30 m intervals, 17 met ENM criteria, two were restricted solid waste and one was hazardous — enabling reuse of most material and avoiding excavation‑stage delays.
iEnvi completed urgent preliminary site investigations at three metal fabrication sites (QLD, NSW, SA) for M&A due diligence, delivering PSI reports within one week and recommending targeted soil testing where moderate–high risks were identified.
iEnvi assessed a 1,800 m3 soil stockpile for an inner-west Sydney council to determine suitability for reuse. Targeted test pits and laboratory analysis showed the material generally met the Excavated Natural Material Order 2014 criteria but required processing and a Specific Resource Recovery Order/Exemption from the NSW EPA before reuse as bunding engineering fill.
iEnvi prepared an Operational Environmental Management Plan (OEMP) and a Pollution Incident Response Management Plan (PIRMP) for a new regional brewery and onsite wastewater treatment plant. The plans incorporated the site’s EPL and local council Trade Waste Agreement to manage wastewater, odour, spills and regulatory obligations ahead of commissioning.
iEnvi completed a confidential PSI and UPSS investigation at a commercial inner-Sydney property to define hydrocarbon impacts to soil, groundwater and soil vapour, and to quantify the likely remediation and compliance implications if the site is converted to residential use.
