Botany Transformation Projects

Welcome, the purpose of this site is to provide information about Orica's various cleanup projects occurring or proposed at Botany.

Environmental Impact Statement for the Groundwater Cleanup Project

 

The Environmental Impact Statement (EIS) assesses the environmental impacts of the Groundwater Cleanup Project and describes the proposed mitigation measures to manage identified impacts. The objectives of the Botany Groundwater Cleanup Project are to use the best practice techniques and processes to:

  • achieve the required level of groundwater containment in both the Primary Containment Area and the Secondary Containment Area and prevent the discharge of contaminants at levels greater than the ANZECC (2000) trigger values into Penrhyn Estuary and Botany Bay
  • achieve a reduction of the concentration of contaminants in the groundwater at the Primary Containment Area to maximum extent practicable
  • clean up containment plumes by:
    • Preventing further contaminant migration through containment lines, allowing gradual cleanup of down gradient areas; and,
    • Assisting DNAPL removal projects by containing potentially increased concentrations of mobilised contaminants
  • minimise air emissions and generation of waste, according to ‘best practice' design standards
  • undertake sufficient monitoring, under the monitoring framework presented in the Groundwater Cleanup Plan to identify changes in concentrations and spatial distribution of the contaminants and groundwater levels, and to assess the effectiveness of the hydraulic containment

Joint Determining Authority Report

On 10 February 2005 the Joint Determining Authority Report was issued under Section 112 of the Environmental Planning and Assessment Act 1979 by the then Department of Environment and Conservation, Department of Infrastructure, Planning and Natural Resources, NSW Maritime, Sydney Water Corporation and Sydney Ports Corporation.

 

These agencies approved the Botany Groundwater Cleanup Project, as described in the EIS, subject to a series of detailed conditions. The Joint Determining Authority Report outlines these conditions and notes the following reasons for the conditions:

  • to ensure that adequate safeguards are in place to protect the environment and human health;
  • to mitigate the potential environmental impacts of the activity;
  • to ensure compliance with relevant statutes and statutory instruments; and
  • to restore the quality of groundwater in and around Botany Industrial Park.

EIS Overview Document

Given the technical nature of the EIS, Orica prepared an overview document that summarises the project scope and the assessment conclusions.
