EPA’s assessment of the CBH Kwinana Fertiliser Project

The EPA has completed its assessment of the CBH Kwinana Fertiliser Project proposed by CBH Ltd and recommended to the Minister for Environment that the proposal may be implemented subject to conditions.

Proposal Kwinana Fertiliser Project Map Kwinana Industrial Site

To develop a facility for the import and storage of dry and liquid urea ammonium nitrate (UAN) fertiliser products. 

The offshore component of the proposal is located within Cockburn Sound, which is an inlet of the Indian Ocean with high environmental values. The proposal involves the construction of a pipeline within Cockburn Sound, which crosses the coastline and continues underground to the onshore facility located within the Kwinana Industrial Area.

Key environmental factors:

  1. Marine environmental quality
  2. Inland waters.

Potential impacts of the proposal on these factors:

  • Accidental spills of liquid UAN to the environment during the transfer of product from vessels to the onshore storage tanks.
  • Spill or leak of liquid UAN from the onshore facility from a fault in the underground pipeline, storage tanks or during the transfer of product for export. 
  • Leaks from the evaporation pond.
  • Uncontained stormwater filtering into shallow aquifer.
  • Diesel and other hydrocarbon spills from the trucks or diesel storage tank. 

Proponent’s measures to mitigate the impacts of the proposal: KGT

  • Using the existing Kwinana Grain Terminal jetty and ship berth (shown in the photo) to avoid additional impacts to the marine environment.
  • Not discharging waste and nutrients from the proposal to the marine environment. 
  • Constructing impervious bunds around the liquid UAN tanks to avoid spills or leaks.
  • Storing fertiliser in enclosed and sealed facilities to avoid spills.
  • Implementing an environmental management plan to minimise, manage and monitor any accidental spills of liquid urea ammonium nitrate.
  • Implementing a water management plan to manage wastewater, stormwater, groundwater and water conservation.

Other agencies and legislation that can regulate the impacts of the proposal:

  • Works approval and registration under Part V of the Environmental Protection Act 1986.
  • Planning approval under the Town Planning Scheme No 2.
  • Planning approval from the Fremantle Port Authority.
  • Building approval from the City of Rockingham.
  • Stormwater management under the Planning and Development Act 2005.

EPA’s recommended conditions:

  • Condition 1 to limit the extent of impacts from the proposal.
  • Condition 2 to protect the marine environmental quality of Cockburn Sound from any spills or leaks.


The EPA’s report is open for a two-week public appeal period, closing Tuesday 22 June 2021. Appeals can be made at www.appealsconvenor.wa.gov.au.
