Westpork Pty Ltd – West Pinjarra (Formerly operated by GD Pork Pty Ltd)


GD Pork Pty Ltd (GD Pork) held Licence L9142/2018/1 for an intensive piggery at Lot 502 Sutters Lane in West Pinjarra, south of Perth.

The Department of Water and Environmental Regulation granted Works Approval W5687/2014/1 to GD Pork on 27 September 2015 allowing for works associated with a proposed expansion of the piggery to increase the production capacity from 3,121 standard pig units (SPU) to 6,854 SPU.

The works approval authorised the construction of new pig sheds, a new wastewater treatment system, including a covered anaerobic pond, a biogas flare and a carcass composting pad.

GD Pork lodged final works approval compliance documentation and a licence amendment application on 12 July 2018. The works approval expired on 27 September 2018. 

The department formed the view that works were not completed according to the works approval and there were significant design and construction shortcomings with what was built.

On 2 November 2018, we were advised that GD Pork had been placed into administration. The sale of the premises to Westpork Pty Ltd (Westpork) has now been finalised.

On 12 April 2019, Westpork became the occupier of the premises and applied to transfer licence L9142/2018/1 into its name. On 17 May 2019, we transferred the licence to Westpork, which is required to comply with the conditions of that licence.

There are no provisions under the Environmental Protection Act 1986 (EP Act) to allow the 12 July 2018 licence amendment application submitted by GD Pork to be transferred to Westpork and Westpork will need to re-apply at an appropriate time, if seeking amendments to the licence.

What is Happening Now?

Westpork has proposed a strategy to address issues associated with odour and waste management at the premises.

This includes desludging of the existing anaerobic pond, which has begun. Our officers visited the premises on 10 July 2019 to observe the progress of establishing an area for the dewatering of sludge.

Desludging of existing ponds is expected to reduce odour emissions once completed.

On 25 July 2019, we issued an Environmental Protection Notice (EPN) to Westpork Pty Ltd to restrict animal numbers on the premises.

This was considered appropriate and necessary to reduce odour emissions from piggery operations, if the proposed strategies to reduce odours and improve waste management, described above, were not carried out in a reasonable time.

Our officers visited the premises again on 12 August 2019 to observe the progress of maintenance works necessary for desludging to begin.

After visiting the premises, we hosted a community consultation at Lesser Hall, Pinjarra. Representatives of the department and Westpork provided an overview of the current and future management of the premises and responded to questions. 

On 24 September 2019 the department amended Westpork’s licence L9142/2018/1 to extend its duration to align with the destocking date specified on the EPN.

Public comment period

We have also recently received and accepted a works approval application from Westpork to carry out improvement works at the Pinjarra Piggery at Lots 502 and 503 Sutters Lane.

The proposed works include construction of a new anaerobic digester, biogas treatment system and flare, and two settlement trenches for primary wastewater treatment. The application is available online for public comment until 15 October 2019.

Desludging of the existing anaerobic pond has started and is likely to be completed by the end of December 2019.

We will continue to carry out regular inspections of the premises to assess compliance with the EPN and to monitor emissions.
