Update from SBI GroupWednesday 30th November 2022

Climatic conditions experienced overnight, as reported by the BOM Frankston/Ballam weather station, were calm with no detectable wind. Whilst the permanent flare was operational consistently from 5am on the morning of Tuesday 29th November 2022, the lack of atmospheric air movement prohibits the dispersion of any gas or odour. Prior to extraction, landfill gas was accumulated within the waste mass. A significant volume of the gas remained within the landfill cell. While the volume is still high, due to the infancy of the flare, calm conditions reduce the atmospheric pressures which allows for the emission of gases lighter than ambient air to escape from the subsurface. As we continue to draw out the gases, the volume within the mass lowers, and has an inverse effect on the external impact of odour. Over time this impact will continue to progressively reduce.

Update from SBI GroupMonday 28th November 2022

After the modifications were completed on Friday, the permanent flare, though fewer than previously experienced, had a small number of shutdowns. Remote and onsite restarting proved successful. Run Energy are on site this morning adjusting the air plates at the base of the burner, with the intent to better control the LFG/air mix which should sustain a more robust flare.

Update from SBI GroupThursday 24th November 2022

The wire mesh sleeve installed this Monday proved less than optimal in its operation. Due to this subpar performance Run Energy have removed the sleeve on Wednesday 23rd November 2022 and flare operation has remained stable. This stability is likely due to the calmer weather experienced over the last two days in contrast to the upset weather conditions of the weekend past. Run Energy have scheduled down time tomorrow, Friday 25th November 2022, to install a smaller sleeve over the gas jet within the burner with the intention of assisting with the wind turbulence experienced in the burner. We anticipate the flare to be reinstated and ignited before close of business tomorrow and SBI with Run Energy will continue to monitor the flare performance over the weekend, remote starting the flare should it become necessary. SBI will provide an update on the modification to the burner and the performance over the weekend on Monday.

Update from SBI GroupMonday 21st November 2022

Close monitoring of the flare with its new burner over the weekend reported initial success through gusty weather experienced on site on Saturday. However, the increase of the extreme inclement weather on Sunday saw intermittent shutdowns. After reviewing the new burner’s performance over the weekend, Run Energy are installing a wire mesh inner sleeve within the burner configuration as well as minor modifications intended to interrupt the wind swirl within the burner which has impacted negatively on the consistency of the ignition. While all these numerous modifications may be seen as problematic, we note that any new plant installation goes through a commissioning phase which will always include infrastructure modifications to suit site specific conditions and optimise performance. SBI regret any inconvenience caused as a result of this commissioning phase and will continue to keep the community updated on our progress.

Update from SBI GroupFriday 18th November 2022

Due to the complexity of the logistics around a three-party swap of operating flares, the plan to swap back to the temporary flare has been postponed. The plan to return the temporary flare remains in place. While Run Energy continue to liaise with the other two parties, they have fabricated a new burner head for our existing permanent flare. This burner is a more robust design with the purpose of weathering extreme wind turbulence experienced within the original burner configuration. The new burner was installed on Thursday 17th November 2022 and reignited late that same day. Overnight monitoring reported the continuous operation of the flare since late yesterday afternoon through to this morning. Close monitoring of the new burner performance will continue through the entirety of the weekend. This new burner maintains the capability of remote restart, should this be necessary. SBI will update the community on Monday as to the flare’s performance over the weekend. Again, we thank you for your patience and apologise for any disruption experienced as a result.

Update from SBI GroupFriday 11th November 2022

As a result of the ongoing intermittent shut downs with the permanent flare experienced to date, SBI and Run Energy have been working in the background to secure the return of the original temp flare. The temporary flare’s original performance exceeded the current permanent flares, and we feel there would be better ongoing success by getting the original reinstated. The flare configuration of the temporary unit differs from the permanent flare and may prove more robust to our localised conditions given its previous operational success on site. The change over is tentatively scheduled for Wednesday and Thursday of next week. The installation has been configured so down time of the flare is as minimal as practical. Once complete, SBI will continue to provide updates as to the ongoing success from the changeover.

Update from SBI GroupTuesday 8th November 2022

The optimal performance of the flare has been inhibited by lower methane concentrations, the cause of which has been identified as the pooling of LFG condensate within the conveyance pipe that leads to the flare. This was the result of settlement of the conveyance pipe within the cell. After identification of the issue, the conveyance pipe has been lifted to allow condensate to gravity feed back to the existing Barrow/J-Trap, which allows for the condensate to drain back into the lined cell and LFG to be more efficiently conveyed through the extraction system as designed. These works were completed today while the flare was temporarily shut down. On completion the flare was restarted and remains operational at a marginally higher methane concentration. Run Energy and SBI will continue to monitor the performance of the LFG extraction infrastructure.

Update from SBI GroupFriday 4th November 2022

Run Energy have worked through several modifications on the permanent flare with varying success. Yesterday afternoon saw the completion of this round of modifications to the flare which reduced the intermittent temporary shut downs overnight to one event. Run Energy restarted the flare remotely and it has remained ignited to present. Close monitoring by Run Energy and SBI shall continue over the weekend with focus on inclement weather forecast towards the end of next week.

Update from SBI GroupThursday 27th October 2022

Work related to the commissioning of the permanent flare continues with the addition of a stainless steel skirt at the base of the flare as intermittent shut downs persist.  This skirt has been custom designed by Run Energy for our site conditions to further reduce the impact we have experienced from wind turbulence. We continue to update the EPA on the progress and are working together to ensure optimal performance.

Update from SBI GroupWednesday 26th October 2022

In response to the intermittent shut downs, Run Energy have been successfully restarting the flare remotely, however issues persist. While we initially attributed these to low methane concentrations from the 6 additional extraction bores, testing this week of individual bores reported sufficient methane concentrations.

High winds experienced on site was then thought to be the cause of the shut downs. As such, an inner funnel was fabricated and installed late yesterday afternoon to combat the suspected adverse wind circulation coursing through the infrastructure. This has allowed for the successful restarting and continuous operation of the flare.

Through the early hours of this morning, intermittent shut downs were once again experienced. Run Energy have again been remotely restarting the flare, which is currently operational. SBI and Run Energy continue to test and configure the parameters of the system. We continue to prioritise the successful extraction and flaring of the landfill gas. We appreciate your patience while we navigate the variables to achieve optimal performance.

Update from SBI GroupMonday 24th October 2022

The 6 additional extraction landfill gas bores were connected to the existing extraction network late last week.  Over the course of this weekend a drop in the methane concentration has been triggering the temporary shutdown of the flare.

Run Energy has been successfully able to remotely restart the flare however the lower methane concentration continues to cause the flare to be shut down for small periods of time.

SBI and Run Energy have today been workshopping options to overcome the lower concentration issue and confirm that the successful extraction and flaring of the landfill gas remains a top priority and we are continuing our efforts to overcome the technical hurdles.

Update from SBI GroupFriday 21st October 2022

On Thursday 20th October 2022 VCAT determined, having regard to the submissions and evidence of all parties, to stay the operation of the decision of EPA to suspend Operating Licence OL000220551, pending the final determination of the merits proceeding, or by further order of the Tribunal.

To this end, SBI will recommence the acceptance of solid inert waste to landfill from Monday 24th October 2022 in line with Operating Licence OL000220551.

Update from SBI GroupMonday 17th October 2022

Whilst we transition from the temporary to permanent landfill gas extraction system, we have just been informed by Run Energy, that the new electronic landfill gas management system has encountered a glitch. 

Whilst the system automatically shuts down and seals, preventing passive venting of landfill gas to atmosphere, active extraction and flaring is not possible until technicians attend. 

We wish to advise that some odour may be detected in the area, until the issue is resolved.  We assure the community that this is a minor problem and rectification thereof is our highest priority. 

Update from SBI GroupTuesday 4th October 2022

SBI received notification from the EPA yesterday that following the submitted response to the Notice of Intent on 13 September, they have decided to suspend the site’s landfill operating license.

This means both landfilling activities and the waste transfer station onsite are now closed.

Whilst extremely disappointed with the decision, SBI continue to liaise closely with the EPA to address current issues, including preparing responses to the outstanding improvement notices.

Update from SBI GroupFriday 30th September 2022

As part of ongoing works to calibrate and maximize performance of the landfill gas extraction system, additional wells will be drilled into the landfill cell to increase efficiency and capacity of the system.

This will be undertaken during the week commencing Monday 3 October 2022. Nearby residents may notice additional odour from the landfill during business hours.

Once complete these works will improve the performance of the landfill gas collection system, and management of landfill odour. 

Update from SBI GroupFriday 16th September 2022

With the onsite landfill gas extraction system now installed and operating, SBI have recommenced landfilling activities onsite this week.

Update from SBI GroupThursday 15th September 2022

The new flare for the onsite landfill gas extraction system was installed on Tuesday 13th September. This means the landfill gas extraction system can start drawing out and burning off (flaring) odourous landfill gas before it enters the atmosphere.

A team of technicians are onsite busy calibrating and balancing the flare to ensure it performs at optimal efficiency. This will be continually monitored and adjusted over the coming days.

Update from SBI GroupTuesday 30th August 2022

Reminder – there will be a community session run by EPA this afternoon (Tuesday 30 August, 4.30pm-6pm) focused on the regulatory response to the odour issue at the Mayone-Bulluk Family and Community Centre 66 Bradman Drive, Cranbourne West. Given the focus on regulatory response, EPA have not requested SBI attend this event.

Update from SBI GroupMonday 29th August 2022

Following a site inspection by EPA late last week and compliance with the appointment of an onsite environmental manager, EPA have now lifted the prohibition notice that was in place, meaning the site can now recommence accepting landfill.

SBI remain focused on improving odour conditions onsite, and therefore will not reopen the facility until we have undertaken further works planned for this week.

Trialing and testing of the landfill gas extraction system continues. While this work is underway, SBI are working to obtain the necessary approvals for the gas flaring system to ensure it is up and running as quickly as possible.

Thanks to the community for your ongoing patience.

If you have any questions about the installed landfill gas extraction system, please contact info@sbigroup.com.au or browse our FAQ’s.

Update from SBI GroupFriday 12th August 2022

On Wednesday 10 August, 2022 SBI received a prohibition notice from EPA preventing the landfill from accepting further waste onsite. The landfill remains closed and the transfer station is not in operation.

In addition to the specialists engaged to install the landfill gas extraction system, SBI has appointed a full time qualified Environmental Manager specialising in landfills, as required in the notice.

Installation of a new landfill gas extraction system was completed last week, allowing for testing to be undertaken this week. Preliminary results indicate that flaring is likely to be the most effective means to address the odour. Currently, SBI are working to obtain all necessary permitting approvals to activate use of a flare.

We apologise to the Cranbourne community and are committed to resolving this issue as quickly as possible.

Update from SBI GroupWednesday 3rd August 2022

The framework for the new landfill gas extraction system has now been installed and system testing will commence on Thursday 4 August and Friday 5 August.

The process of testing could possibly release some odour into the atmosphere.

Testing will be undertaken in the middle of the day when weather conditions are optimal for dispersion, however surrounding communities may experience some odour.

Update from SBI GroupTuesday 2nd August 2022

Works continue onsite to install the new landfill gas extraction and treatment system, with the final wells for this system being drilled this week.

These works have generated some additional odour in surrounding communities in recent days.

Once installed, the system will be tested and calibrated before being commissioned.

Thank you to everyone we spoke to on Friday and Saturday at the community information sessions. We have collated all questions received and have published answers to each here.

Nominations for the Community Consultative Committee close on Friday 5 August. If you would like a nomination form please email info@sbigroup.com.au.

We hope to hold the first meeting as soon as possible.

Update from SBI GroupFriday 22nd July 2022

Experts will be onsite at SBI Landfill from next week installing additional systems to capture, extract, and treat odour generated onsite. This work involves drilling gas wells into the existing landfill.

SBI will deploy onsite odour suppressants and works will be timed to minimize the potential for odour impacts on the community, however surrounding communities may detect increased odour from the landfill between Monday 25 July and Wednesday 3 August while these works are underway.

These improvements to the onsite landfill gas extraction system are needed to meet the requirements of the Environment Protection Authority’s Improvement Notice.

Update from SBI GroupThursday 21st July 2022

We have now concluded trucking the stagnant water offsite. Suction trucks continue to actively remove excess storm water to prevent any further pooling.

We are also undertaking further measures to improve onsite landfill gas management. This process includes implementing additional systems to capture, extract, and treat odour via our onsite gas collection systems.

We have engaged experts to provide system recommendations and will make the necessary changes to address the Environment Protection Authority’s Improvement Notice. We will provide further information as we progress with this process. 

Expressions of Interest now open for Community Consultative Committee

Going forward, SBI are planning to re-form a Community Consultative Committee providing a forum for discussion between the community, SBI and other stakeholders on issues relating to the landfill’s operations, and to act as a conduit to keep the community informed of activities at the landfill. 

If you would like to nominate yourself for this Committee, please email info@sbigroup.com.au by 5pm Friday 5 August.

Update from SBI GroupMonday 11th July 2022

SBI continues work to address odour issues at the landfill site in Cranbourne.

Trucking of stagnant water offsite has been ongoing and should be concluded this week.

Neutralising agents are being applied to the water and air in the immediate area while these works are underway.

The combination of these activities should result in the dissipation of odour in the coming days. 

We are in close contact with and continue to comply with all directions of the Environment Protection Authority (EPA).

We thank the community for reporting odour to EPA as this data, along with weather and onsite monitoring, are assisting with our understanding of the impacts to our local communities.

We sincerely apologise to our neighbours for the inconvenience this has caused. SBI has been part of the local community for over 30 years – we are employing all mitigations to address the issue and will not rest until it is fully resolved.

Update from SBI GroupThursday 7th July 2022

Progress has been made on the removal of stagnant water which has been the source of recent odour we have been working diligently to address.

Thank you to the community that has reached out to us and provided feedback. Based on these recent queries we have prepared a list of Frequently Asked Questions addressing the odour and the processes we have undertaken to resolve it.

SBI Landfill Cranbourne  – Frequently Asked Questions

What does SBI do?

SBI Group Cranbourne operates a solid inert waste landfill licensed to accept waste that cannot be further recycled including construction, demolition, commercial and industrial wastes.

How is this inert waste managed?

Waste is placed in purposefully engineered cells that are created meeting the Best Practice Environmental Management standards required by the Environment Protection Authority (EPA).

To ensure waste stays in place, daily cover is applied and compacted using heavy machinery. Any liquid generated from the waste is captured, pumped to a holding tank and transported off site.

What has happened to cause the odour at the SBI landfill?

Unfortunately SBI Group’s Cranbourne landfill has been releasing increased odour in recent weeks, which escalated late last week.

A pool of water had collected and remained stagnant after a high amount of rainfall. This water would normally have migrated into the dedicated groundwater collection system, however due to the high amount of rainfall the system was overrun with silt and did not allow the water to escape.

What is being done to resolve the issue?

SBI Group have been working tirelessly to resolve the issue. We are in close contact with the EPA as we work to address this issue.

A range of measures deployed onsite to treat, remove and mitigate the odour over a number of days have been implemented and unfortunately have been unsuccessful in completely removing odour.

In order to expedite removal of the odour, we have been trucking the stagnant water offsite since last Friday afternoon, and hope to complete this operation in the next week.

While this process is underway we are applying additional measures including:

  • The application of a neutralising spray to help mitigate odour in the immediate area 
  •  An odour neutralising solution is being added to the remaining stagnant water while we continue to remove it from site.

Why am I still smelling the odour?

Though measures to remove the source of odour have been successful, unfortunately due to limited wind and the presence of temperature inversions overnight, remnant odour has continued to impact surrounding communities.   

How long will this last?

With the odour source being removed from site, we expect that with changed weather conditions the issue will significantly dissipate in the coming days.

We sincerely apologise to our neighbours for the inconvenience this has caused.

Statement from SBI GroupTuesday 5th July 2022

Unfortunately SBI Group’s Cranbourne landfill has been releasing increased odour in recent weeks, which has escalated late last week.

The recent odour issue has been caused by stagnant water generated from a water pond in the former quarry void onsite. Due to prevailing winds this has had particular impact on neighbouring communities.

We have been working closely with the EPA to resolve this issue, but unfortunately attempts to treat the water onsite have been unsuccessful, and as a result we have been trucking this stagnant water offsite since Friday afternoon.

This along with a number of other efforts has assisted to reduce the odour, however air inversions overnight has meant nearby communities are still experiencing odour.

We sincerely apologise to our neighbours for the inconvenience this has caused and thank you for your patience while we address this issue.
