Progress Reports

Progress Reports provide details of Orica's cleanup progress against the Voluntary Management Proposal (VMP), and associated Groundwater Remediation and Management Plan. In 2017 the frequency of groundwater and surface water monitoring was reduced from quarterly to biannual.

Groundwater Remediation Strategy Reviews

Orica conducts a review of the Botany Groundwater Remediation Strategy every three years, involving at least three international industry experts, local consultants, appropriate representatives of the Independent Monitoring Committee (IMC) and the NSW Environment Protection Authority (EPA).

 

 

Community Forum

A Community Forum was first held in 2017  following the Botany Groundwater Strategy Review Workshop and again in 2020 to share findings with the broader community with International experts and the IMC hydrogeologist.

Annual Technology Review Reports

In accordance with the VMP, Orica must consider best practice technology in the remediation of Dense Non-Aqueous Phase Liquid (DNAPL) and groundwater containing dissolved phase contaminants, through continued review of relevant, emerging technologies and ongoing investigation of the practical application and effectiveness of these technologies in relation to the remediation. Orica must also provide an annual written report to the EPA on the progress of the reviews and investigations.

Consolidated Human Health Risk Assessment

Human health risk assessments (HHRA) have been undertaken to assess potential human health risks in areas surrounding the Botany Industrial Park (BIP) since 1996. Assessments were first pulled together in a Consolidated Human Health Risk Assessment in 2005 and this document is updated every 5 years.

The 2015 CHHRA was submitted to the NSW EPA and was revised in 2017 to address comments received from NSW EPA and NSW Health. The report dated 2018 is provided below.  

 

GTP Environmental Impact Statement 

An Environmental Impact Statement (EIS) was prepared for the GTP in 2004 to assess the environmental impacts of the Botany Groundwater Cleanup Project. It described the proposed mitigation measures to manage identified impacts.                                                                                                                                                                                                                                                                                                                                    Back to top

Conceptual Site Model Report

A Conceptual Site Model (CSM) was developed for the Botany Groundwater Cleanup Project, and other current contamination projects at Botany Industrial Park (BIP). The objective of the CSM is to summarise and encapsulate pertinent information derived from the many studies undertaken at BIP and surrounding areas, including:

  • the history of industrial activity and land development at BIP and surrounding properties, including potentially contaminating activities and land uses;
  • the progression and scope of investigation and remedial works undertaken by Orica and its predecessor ICI associated with the Botany Groundwater Cleanup Project;
  • the environmental setting at BIP and surrounding affected properties;
  • the inferred sources, nature and extent of contamination, including the various media affected by the contamination;
  • the mechanisms for transport and attenuation of the contaminants, and exposure of identified receptors to the contamination;
  • the potential health and environmental risks which the identified contamination is inferred to pose; and
  • effects of current remedial practices, and the results of previous remediation work and trials.

Since the main contamination migration and exposure issues associated with the BIP are related to groundwater, the CSM is primarily a hydrogeological document. However, as indicated above, summary data and relevant information are also included for soil, surface water, sediment, biota and vapour phase contamination. This report is periodically updated, and the most recent update was completed in September 2017.
