MINE REHABILITATION

EI Australia managed the excavation, waste classification and off-site disposal of embankment materials as part of a Mine Rehabilitation Project. EI Australia’s involvement included in-situ assessment of mined overburden soils, excavation and stockpiling of slag filling and naturally-occurring PAH-rich soils, prior to waste classification testing and landfill disposal.

Landfill disposal volumes and costs were minimised by separating, large volumes of validated soils for reuse as filling on a nearby residential estate, in accordance with a site-specific Remedial Action Plan (RAP) and with NSW EPA Site Auditor approval.

Value Added / Beneficial outcomes for Client:

Through strategic waste segregation and careful waste classification assessment and material movement tracking, EI enabled the Client to comply with current relevant waste regulations and recover over 90% of the waste soils for approved reuse on a nearby residential estate, while minimising waste disposal costs for impacted soils disposed to licensed waste landfill.

WASTE TRANSFER SITE

As part of a long-term, waste soil quality monitoring programme at a former EPA-approved, waste transfer station located close to the central Sydney urban area, EI Australia managed the routine material characterisation, waste classification and reporting process for waste soils intended for off-site disposal to licensed waste landfill facilities.

All waste classification reporting was conducted in accordance with relevant environmental guidelines, in compliance with current waste regulations at the time of the project.

Value Added / Beneficial outcomes for Client:

Assisted the Client in achieving compliance with EPA license conditions and other regulatory requirements.

LAND REDEVELOPMENT FOR COMMERCIAL & RESIDENTIAL AREAS

This 6000 square metre former industrial site, which included a former James Hardie factory, Camellia Chemical factory and a solvent drum recycling facility, was to be redeveloped for commercial, residential and recreational uses with basement car parking.

With the goal of making the site suitable for the proposed land uses EI assessed soils, groundwater and geotechnical conditions and developed a preliminary RAP for the on-site encapsulation of over 70 000 cubic metres of buried, asbestos-containing materials and localised, TRH/PAHs-impacted clinker waste.

The remediation strategy included onsite bio-pile treatment of soils impacted with petroleum and VOCs. EI also provided technical inputs to the landfill cell design concept.

VALUE ADDED / BENEFICIAL OUTCOMES FOR CLIENT:

EI progressed the site characterisation process to enable RAP revisions and to better inform related disciplines and consenting authorities during the review and approval process.
