West Erregulla Processing Plant and Pipeline

Closed 11 Jun 2021

Opened 4 Jun 2021


AGI Operations Pty Limited propose to construct and operate a gas processing plant and pipeline associated with the development of the West Erregulla gas field, located approximately 230 kilometres (km) north-east of Perth, and 50 km south-east of Dongara, Western Australia.  

The processing plant will process gas produced from third party owned upstream wells. The processed gas will then be transported via a new interconnecting pipeline to the Dampier to Bunbury Natural Gas Pipeline (DBNGP). 

The proposal includes a gas processing facility with a nominal production capacity of 87 terajoules per day, a 16.5 km interconnecting buried gas pipeline, a custody transfer metering facility at the DBNGP tie in point, a pig launcher station, evaporation pond, a power generation system, flare system, incinerator, fire water system, accommodation and office facilities, water treatment package, back up diesel generator and communications system.  

The proposal will result in the clearing of up to 90 hectares (ha) of native vegetation within a 213 ha Development Envelope. 

The life of the proposal is for 60 years.

Why your views matter

At this initial stage of the EIA process, comment is simply sought on whether or not the EPA should assess a proposal and, if so, what level of assessment is considered appropriate.

What happens next

Following the seven day public comment period and consideration of any comments received, the EPA will decide whether or not this proposal requires environmental impact assessment and, if so, what level of assessment will be applied.

The EPA's decisions on level of assessment are released each Monday on the EPA's website.
