Eastern Creek

Update on Eastern Creek Landfill Facility

Published on 13th May 2022

Update 13 May

BINGO continues to progress odour mitigation activities in its landfill facility in Eastern Creek.
 
Since 3 May, this has included:
  • The relocation of one flare to the South-Eastern corner of the landfill to assist in gas extraction within the area
  • Adding an additional gas extraction line to the leachate riser (two extraction lines are now installed)
  • Completing raised clay capping around the entry to the leachate riser to mitigate water entry to the leachate riser
  • The installation of six pin wells at depths of six metres on the South wall of the landfill. 

The drilling of wells can sometimes result in temporary emission spikes, but the wells are immediately capped following drilling until they are connected to the gas pipeline.
 
On 14 and 15 May pipework will be laid on the surface (to avoid digging) to allow the six new wells to be connected to the main gas line. All six wells are expected to be connected by Sunday evening.
 
All six flares in the landfill are operating. A seventh flare has been ordered to add further capacity. This should arrive onsite in early July.
 
BINGO continues to keep the NSW Environment Protection Authority (EPA) informed of its work activities.

Update 3 May

BINGO continues to undertake remedial and preventative measure to address any potential odour from its landfill facility at Eastern creek.

Over the past week BINGO has:

  • connected five additional gas collection wells in the south-east area of the landfill to improve capture capacity; and
  • repaired damage to Flare 2 sustained during the heavy rains of March and April. All six flares within the landfill are now fully-operational.


BINGO would also like to inform the community that works to increase the height of the leachate riser have been postponed for approximately two months when weather conditions are expected to be more favourable. We will provide the community with notice and details of the leachate riser works in advanced of commencing activities.

We encourage community members to contact our environmental hotline on 1300 032 747 or contact us, if they have any concerns.

Update 22 April

BINGO continues to take preventive actions at its Eastern Creek facility to manage odour emissions triggered by environmental factors. This includes the engagement of an additional independent expert to investigate and identify potential sources of odour at the Eastern Creek facility, and  to recommend immediate and intermediate mitigation measures to fix identified potential sources of odour.  
 
This independent expert has identified that the substantial increase in rainfall associated with persistent La Nina conditions along the east coast of Australia impacted the efficacy of the sites integrated landfill gas (LFG) collection and treatment system.

BINGO is in the process of  implementing the following measures:
  • Establishing four additional gas collection wells for connection in the south-east area of the landfill to improve capture capacity;
  • Removing all water, leachate and sludge pooled around the leachate riser to allow for the re-seal of the leachate sump and re-establish LFG extraction at the leachate sump;
  • Ensuring that the intermediate cover surface across the landfill in all areas not being actively used is maintained by compacting, rolling and grading to remove rutting and reduce local pooling;
  • Installing five new LFG extraction wells into ‘recently tipped wastes’ areas of the landfill;
  • Completing the repair of 2 damaged gas wells at the riser – which wasflooded during March rainfall - and the installation of a temporary pipeline to reconnect these to flares while the riser lift and rectification work is in progress;
  • Working with Sydney Water to increase rates of leachate extraction while continually pumping pooled surface water to the sewer.

In addition, BINGO has:
  • Secured development approval for the installation of a permanent landfill gas capture and flaring system, approved under MOD10. The project is currently under construction with operation forecast for late 2022;
  • Undertaken essential maintenance and rectification works of gas collection wells in the vicinity of riser impacted by March flooding event;
  • Finalised planning for a new leachate riser lift
  • Undertaken critical maintenance works and commissioning of a sixth flare scheduled for completion on 27 April 2022;
  • Commenced the replacement of the leachate extraction pump. scheduled for installation at the end of April;
  • Commenced trenching and connection works to five recently installed gas collection works with 5 wells to be connected to the main landfill gas lines by  the end of April.

If you do experience odour, please let us know through our environmental hotline at 1300 032 747 or contact us.

Easter Weekend Operations

BINGO would like to inform the local community adjacent to our Eastern Creek site that we will continue to have a team in our landfill working to monitor and manage landfill gas and odour over the Eastern Weekend (15-18 April 2022).
 
This team will also be continuing to carry out repairs to damage sustained to our landfill gas management system caused by the excessive rains in March.
 
These works will include:
  • Surveying landfill for potential odour sources.
  • Continued pumping of ponded water in preparation for remediation of wells situated around the riser.
  • Regrading of any locally ponded areas.
  • Pumping of water catchment dam at base of access ramp.
  • Applying cover material to all areas that have been affected by heavy rains.
 
We encourage members of the public who may have any questions or concerns to contact us on our environmental hotline at 1300 032 747 during this time.

Update 11 April

BINGO advices that today Monday 11 April 2022, drilling has commenced on an additional five wells in our Eastern Creek Landfill facility as part of improvements to our landfill gas management system following recent impacts due to heavy rain events in March and April 2022.
 
We advise the community that drilling operations may result in a temporary increase in odour from the site. Drilling operations are expected to continue for the next eight days. These works are expected to improve the long term performance of our landfill gas capture and treatment system.
 
If you do experience odour, please let us know through our environmental hotline at 1300 032 747 or contact us.

Update 8 April

BINGO continues to undertake remedial and preventative measures to address any potential odour from its landfill facility at Eastern Creek.

 Activities in the past week have included: 

  • The installation of sixth flare on 2 April. This is now operating.
  • Maintaining the operation of a minimum of four flares while moving two flares to higher ground
  • The ongoing repair of flare two, which will be offline until mid-April. Replacement parts are being air freighted from the UK   
  • The connection of four additional gas collection wells that were originally planned for connection with the commissioning of the permanent flare system.  This will further improve the collection of gas along the southern side of the landfill
  • The arrival of the drill rig onsite on 7 April, ready for works to commence next week
  • Daily control checks and maintenance of the leachate treatment plant (LTP), and the trialling of chemical treatments to reduce odour
  • Preventative maintenance on one of four tanks in the LTP, while ensuring the remainder of the treatment plant remained online
  • Surface water catchment at base of access road and the installation of additional pumps
  • Daily monitoring for surface gas and odour

We are also accelerating our ~$4 million landfill upgrade program, otherwise known as our permanent flare system, which was approved by the NSW Department of Planning in March. 

This program includes the following activities being carried out over the following week:

  • The drilling of five additional 32 metre wells in the centre of the landfill (a further seven will be drilled at a later date as part of the same system)
  • The laying and connecting of pipelines to the main line, which will transport the gas to the  flares

The unprecedented recent rain events have made operations in the landfill challenging but the team is working around the clock to ensure the issue is properly managed.

Update 28 March

Since 15 March 2022, BINGO has a received a small number of complaints from the local community regarding odour in the Eastern Creek area. We’d like to provide the local community with an update on the actions we have taken to address these complaints.
 
While our integrated landfill gas management system has been operating effectively, the heavy rainfall event through January to March this year (which recorded the highest rainfall on record since 1859) has temporarily impacted the efficacy of the system due to localised flooding within the landfill. Covering and capping within the landfill has also become more difficult due to the continued heavy rainfall.
 
What have we done to respond to the issue? 
  • BINGO previously identified that three of our five temporary flares were not operating at full efficacy from 10 - 15 March due to condensation/moisture from the recent heavy rain entering the electrical control systems. Four flares continue to operate efficiently, including one high capacity flare (with a capacity double the other flares).
  • A fifth flare is expected to have completed maintenance and refurbishment activities whereby it is expected to be operational by the end of March 2022
  • A sixth flare is expected to be operational by the 5th April 2022.
  • BINGO continues to undertake offsite odour monitoring in neighbouring community residential areas
  • BINGO continues to undertake onsite landfill gas monitoring
  • BINGO landfill Filling Plan has been approved and is being executed.
  • Working with Sydney Water to increase rates of leachate extraction while continually pumping pooled surface water to the sewer. Sub-surface and surface water pumping recommenced on 22 March 2022
  • We are continuing to monitor and repair as necessary damage to cover, and capping caused by excessive rainfall
  • We have completed a review of the gas extraction system and expedited correction of issues such as build-up of condensate in the pipes
 
Actions currently underway
Further actions currently underway include the following: 
  • The implementation of the permanent flare system, which was approved this month
  • Establishing four additional gas collection wells proposed for connection in the south-east area of the landfill to improve capture capacity when the full six flares are operational by 5 April 2022
  • Reviewing options for upgrading monitoring requirements
  • Procurement of permanent flare and early site establishment preparatory works. CAPEX of $3.5M has been approved
  • Planning for a new leachate riser lift is in the final stages and ready to activate when conditions permit
  • Evaluating leachate management plant upgrade and interim management solutions, with a focus on improving plant reliability and availability
 
We encourage members of the public who may have any questions or concerns to contact us on our environmental hotline at 1300 032 747 or through our contact us page. 

Update 17 March

BINGO advises that four of the five flares in its Eastern Creek landfill are now operating at full capacity. The fifth flare is undergoing further repair but is expected to be back online by 24 March, and a new, sixth flare is expected to be operational by the end of March 2022. BINGO’s development application for the permanent flare system was recently approved by the NSW Department of Planning and Environment. The installation of the permanent flare system is being progressed as quickly and possible and is expected to be completed later this year.

Update 16 March

BINGO’s Eastern Creek facility received an odour complaint on 14 August, and a second on 16 August. In light of these complaints, on 16 August BINGO made the decision to relinquish its temporary approval to accept putrescible waste into its Eastern Creek recycling facility. This approval had been granted to alleviate the pressure on Greater Sydney’s putrescible waste network caused by the recent heavy rain event. All putrescible waste will be removed from the recycling facility by 18 March and no more will be accepted in the facility.
 

BINGO continues to undertake ongoing odour mitigation activities on site. If you do detect odour, please contact BINGO’s environmental hotline on 1300 032 747.

Update 15 March

Flare maintenance

BINGO advises that three flares in its landfill are currently undergoing repair and maintenance today in response to impacts posed by recent heavy rainfall events. Two flares are expected to be back online on Thursday, 17 March. Two flares continue to operate efficiently, including one high capacity flare (with a capacity double the other flares). A sixth flare is expected to be operational by the end of March 2022.
 

Update 14 March

BINGO Eastern Creek facility to assist in critical flood clean up

Following the recent destructive flooding events across NSW, the state government has requested assistance from BINGO’s Eastern Creek facility to assist in the safe disposal of flood waste. BINGO would like to inform the community that the Environmental Protection Agency (EPA) has given BINGO approval to accept flood waste into its Eastern Creek landfill. We would like to provide an assurance to community members that disposal of flood waste will not cause odour issues at BINGO’s facility. BINGO have put in place a number of odour mitigation processes, including our Eastern Creek landfill gas collection and management system. Our Eastern Creek landfill gas collection and management system has been operational since June 2021 and continues to be working effectively.
 
We encourage any concerned community members to call our environmental hotline on 1300 032 747

Update 27 August

Flares back online
 

BINGO advises that all three flares in its landfill facility at Eastern Creek are now back online.

Update 25 August

Landfill flare maintenance

BINGO advises that maintenance on one of the flares in our Eastern Creek landfill is close to completion and the flare is expected to be back online tomorrow, Thursday 26 August.

Update 13 August

Landfill flare under maintenance at Eastern Creek


BINGO advises that one of the flares in our Eastern Creek landfill has been shut down today for maintenance and is currently not operating. The remainder of the gas collection and management system, including the two remaining flares, is operating effectively. 
 
BINGO will provide further updates on the status of the flare as appropriate.

Update 22 June

Drilling for final wells underway

 
Drilling has commenced for the final four wells as part of the advanced gas collection and management system being installed at BINGO’s Eastern Creek facility.
 
After a significant reduction in odour emissions from the site over the past two weeks since the installation of the third flare, drilling operations may result in a temporary increase in odour emissions from the site.
 
Drilling operations are expected to continue for the next two to three days.
 
If you do experience odour, please let us know through our environmental hotline at 1300 032 747 or at bingoindustries.com.au/contact-us

Update 17 June

Third flare now operational. Fourth flare to be added, along with additional wells

 
BINGO has installed a third flare as part of its advanced gas collection and management system at its Eastern Creek landfill. The three flares and 27 wells are now operating at close to 100%, and we now intend to add a fourth flare and drill an additional four wells.
 
The system continues to operate effectively. This has resulted in a substantial reduction in odour emissions from the facility, and subsequently we have not received an odour complaint since 6 June 2021. The EPA has confirmed that they have experienced a similar reduction in odour complaints. 
 
The installation of the gas collection and management system was fast-tracked in order to resolve the issue as expeditiously as possible. The international contractor installing the new system has advised us that they have never seen a comparable system installed in such a short time-frame.
 
We continue to conduct odour surveys in surrounding communities multiple times per day, and we have a dedicated team monitoring the surface of the landfill. If an emission site is identified in the landfill, measures are taken as soon as possible to provide further compaction and cover to the area.
 
While there is further work to be undertaken, we are confident that we now have the matter well in hand.

Update 31 May

Two flares operating at Eastern Creek


BINGO now has two flares operating at its Eastern Creek site as part of the company’s odour mitigation activities (see photo below). The plumes from the flares are a result of the combustion of gas from the landfill, a process that eliminates the odour from this gas. By the close of business on Tuesday 1 June all wells are expected to be connected to these flares and the gas collection and management system will be fully operational. 

The system is already operating efficiently and since the commissioning of the second flare no odour has been detected from the site. BINGO believes it now has the matter well in hand.

It should be noted that there are a significant number of other potential sources of odour in this area, including other landfills, waste transfer stations, food manufacturers, composting facilities, bitumen producers, and major sewer lines.  Ongoing complaints from the community are increasingly unlikely to be caused by BINGO’s facility. The EPA has already confirmed that recent odour surveys have detected odour from other facilities.

Update 24 May

Stage 1 of gas collection and management system installed and operational; Stage 2 to be installed this week

 
BINGO has completed the installation of Stage 1 of the gas collection and management system at Eastern Creek as part of the company’s ongoing odour mitigation activities.
 
Stage 1, which includes the installation of a flare and 15 gas wells, was completed last week and work on Stage 2 is well underway. Stage 2 comprises a second, larger flare and an additional six wells and is expected to be completed by the end of this week.
 
Stage 2 is expected to resolve the matter for the long-term. The modular system currently being installed will allow for future expansion to ensure effective control of odour for the life of the landfill.

Once the landfill gas collection and management system has been installed it will be continually monitored to ensure it is operating effectively.

Update 17 May

BINGO installing odour mitigation gas collection and management system


As part of BINGO’s ongoing odour mitigation activities at Eastern Creek, we have engaged a leading international contractor to install a gas collection and management system in our landfill. 

Work commenced on 13 May 2021 and included the following activities:
 
  • monitoring of landfill gas emissions in the surface of the landfill to identify hot spots for targeted control; and
  • drilling and installation of gas wells connected to a flare which will collect and destroy odorous gases before they reach the surface of the landfill.

The system has a modular design that will allow for future expansion to ensure effective control of odour from the site upon operation and in future as landfilling continues

Following commissioning of the landfill gas collection and treatment system it will be continually monitored to ensure it is operated effectively.

The landfill gas and treatment system currently being installed will result in a significant improvement in odour emissions currently emanating from the site. These systems are routinely employed on landfills across the world for treatment of odour arising from landfill gas emissions.

There may be the potential for temporary unpleasant odour during well installation. A number of measures will be employed to control potential odour emissions as a result of drilling, including:
 
  • work will only be undertaken during daylight hours when odours are more readily dispersed and controlled;
  • a deodoriser will be employed on site at the drilling locations to treat any odours at the source of drilling;
  • any waste exhumed during drilling will be landfilled and covered immediately; 
  • gas wells will be covered and capped when left overnight if incomplete; and
  • odour monitoring will continue to be undertaken to allow responsive management.

Given BINGO’s commitment to resolving this issue we continue to expedite the delivery of all actions required to mitigate the odour issue at our site. 

The timeline for the installation of the gas management infrastructure is as follows: 
 
Action Timeframe
Gas drilling contractor and equipment arrives on site 13 May 2021
Gas well drilling and installation commences 14 – 17 May 2021
Connect gas wells to collection infrastructure 15 – 17 May 2021
Install and connect flare to gas collection system 15 – 18 May 2021
Commission flare Week commencing 17 May 2021
Progressive installation and connection of additional gas wells (as required) to the flare for the period 17 May – 27 May 2021

Update: 10th May 2021

BINGO would like to provide the local community with an update on the actions we have taken to address the odour issue at our Eastern Creek landfill facility and to apologise for its occurrence.

As soon as we were made aware of odour within the local community in early April, we took the following immediate actions:

  • commissioning an odour audit and review to assist in identifying potential sources of odour;
  • commencing additional daily inspections of the landfill, including leachate tanks, to identify any areas of odour; and
  • if areas of odour were identified in the landfill, additional cover, in excess of licence requirements, was applied.


The NSW Environment Protection Agency (EPA) advised BINGO that two potential sources of odour were identified in the landfill - the leachate riser and vent pipe. The high levels of leachate impacting the leachate riser was the result of a one in a hundred-year rain event in March where significant volumes of water entered the landfill, increasing the potential for the production of odour.  Our landfill accepts inert, non-putrescible waste typically derived from construction and demolition and commercial and industrial sources and does not accept putrescible waste (such as waste in domestic red bins and food waste).  Odour is therefore not a typical issue at our facility, as it may otherwise be for other surrounding facilities.

BINGO took the following immediate actions in consultation with the EPA:

  • to manage any immediate odour within the vicinity of the leachate riser and vent, applied lime to those areas to disperse any potential odour;
  • expanded the scope of the odour audit given feedback on the location of the community complaints from the EPA;
  • commissioned a consultant to undertake a gas assessment (taking samples from the leachate tanks and riser) to determine whether there were specific chemical compounds responsible for the odours detected;
  • significantly reduced the tip face and application of additional cover and further compaction of fill at various locations across landfill; and
  • appointed staff to attend site outside of operating hours to monitor odour.

We then sealed the gaps or cracks in the riser, added mulch as a bio-filter to both the riser and the vent and applied additional cover.

In addition, we have:
  • applied activated carbon to impacted areas, as advised by our consultants;
  • undertaken leachate riser extension, including waterproofing and leachate pump replacement;
  • commenced an investigation into the effectiveness of an activated carbon filter to fit the leachate riser;
  • undertaken further monitoring and “hot spot” identification;
  • worked with Sydney Water to increase rates of leachate extraction;
  • increased the volume of clean soil we apply across the entire landfill and
  • investigated gas capture and management options.

We are expediting the installation of new infrastructure to collect and treat landfill gas. This infrastructure will resolve the problem for the long-term.

We are very conscious of the impact odour can have on local residents and once again we sincerely apologise for any discomfort and inconvenience this may have caused you in recent weeks. We are doing everything we can to manage the issue on our site.

We intend to fully resolve this matter as soon as possible and ensure it does not occur again in the future.

We encourage members of the public who may have any questions or concerns to contact us on our environmental hotline at 1300 032 747 or at bingoindustries.com.au/contact-us.
