State Property Authority Award Hunters Hill

Overview

Enviropacific Services has been awarded the contract with State Property Authority (SPA), NSW to remediate the Hunters Hill Site. The site is located on Sydney Harbour and the foreshore area is included within the remedial area of the site. The remediation work will involve the excavation and removal of all material within the site to bedrock. The remediation of the Hunters Hill site is considered a high profile environmental and civil engineering project taking in to consideration, the narrow site access, steep site topography, sensitive site location on Sydney Harbour foreshore, close proximity to surrounding residential community and environment, and radioactive nature of the waste. The design of the remediation process for the Hunter’s Hill site was developed by Enviropacific Services in conjunction with the relevant authorities to ensure potential environmental and health risks related to the project are minimised or eliminated where possible. Detailed health and environmental planning processes are being undertaken as part of the State Planning Approval process, and the project will operate under stringent safety and environmental protocols as developed in conjunction with the Australian Nuclear Science and Technology Organisation (ANSTO). Preliminary works currently undertaken include the development of the Remediation Action Plan and Site Safety Management Plans. Due to the steep topography of the site and absence of vehicular site access Enviropacific will construct and utilise a tower crane for the duration of the project to move equipment and materials in and out of the site. All material will be transported using lined and sealed containers to minimise the risk of impacts on external traffic during transportation. In addition to the detailed excavation and disposal activities, a portion of the excavated soil will be immobilised under the DECCW Waste Immobilisation Approval, and all stormwater and any groundwater will be processed through an onsite water treatment plant to ensure discharged water complies with relevant water quality standards. Civil components of the project will include the construction of crane footings and loading platforms, diversion and reconstruction of services, backfilling of foreshore area following excavation, and the reconstruction or repair of the sandstone seawall.

Remediation of Evans Head Memorial Aerodrome

Overview

Enviropacific are currently undertaking the remediation of the Evans Head Memorial Aerodrome for the Richmond Valley Council on the NSW Far North Coast.  The contaminants are confined to the soil surface; as such the site remediation involves a surface scrapping of the air field (45,000m2) with all stockpile soil characterised through laboratory analysis.   Contaminated soil will be bioremediated to reduce hydrocarbon concentrations and allow reuse of material onsite.  Any material impacted by asbestos will be removed from site to a licensed landfill.  We anticipate a 95% recovery and reuse of excavated material at the Aerodrome.

Summary

  • Excavation of over 27,000 m3 soil from the 4.5 hectare site
  • Demolition of concrete and asphalt structures
  • Bioremediation of impacted soils to allow reuse on-site
  • Segregation and management of asbestos material
  • Development & implementation of detailed management plans
  • Stringent environmental monitoring programme
  • preparation of the Groundwater and Validation SAP QA/QC plans

Progress at Port Pirie

Overview

Enviropacific are undertaking a project at Nyrstar Port Pirie, approximately two and a half hours drive to the north of Adelaide. The project involves the  immobilisation of approximately 2200 tonne of contaminated roaster bricks using Enviropacifics Hitachi Soil Recycler. The bricks are initially pre-treated onsite to 12mm minus given the amount of oversize material. Enviropacific are currently treating the material onsite. The treatment process is designed to reduce the leachable concentrations of the heavy metals to below Low Level Contaminated Waste Criteria (LLCW) to allow disposal of the material to a landfill authorised to receive LLCW and treated LLCW with EPA approval. Samples will be collected of the material to confirm successful treatment via ASLP and MEP analysis. The project is expected to be completed by late March this year.
