Project Description

Hutchinson Builders engaged Epic on behalf of Bunnings to undertake an environmental investigation, remediation and validation works at the former Toowoomba Foundry. The site has been subjected to industrial activity since the late 1800s with a significant volume of foundry wastes incorporated into the site. A number of historical investigations have been undertaken at the site, which identified fill and groundwater contaminated with hydrocarbons and metals. The site was listed on the EMR and subject to a DEHP endorsed SMP. Epic was able to revise the proposed development strategy to enable the Site to be redeveloped for commercial use while minimising commercial risk and environmental liabilities.

By working in close collaboration with Hutchinson Builders and Bunnings, Epic was able to achieve the following outcomes:

  • The removal of two smaller lots (which formed part of the Toowoomba foundry property) from the Department of Environment and Heritage Protection (EHP) Environmental Management Register (EMR);
  • Development and implementation of a remediation strategy which allowed the majority of contaminated soil to be managed on site, resulting in a significant reduction in off-site soil disposal costs for the project;
  • Provided on site advice during remediation to ensure areas of unexpected impacts were assessed and managed in accordance with the SMP;
  • Developed a project specific Validation Sampling and Analysis Plan to the appointed Contaminated Land Auditor demonstrating a cost-effective approach to the management of legacy waste issues;
  • Provided cost effective design options for encapsulation of landscaped areas of the site and minimise surface water infiltration.
