The role of the Environment Agency

Valencia Waste Management Limited holds an environmental permit for waste activities (disposal by landfill) and the Environment Agency regulates the site to monitor compliance with the conditions in the permit.

The Environment Agency’s job is to balance the needs of people and the environment. As part of this we are responsible for permitting and regulating landfill sites, so they don’t harm people or the environment. We can never totally remove the impact, but it is our duty to set high standards for operators and require them to meet these even where that is difficult.

The Environment Agency carries out monitoring and checks to see if an operator is meeting the standards we set. When they don’t, we investigate and take action. In doing this we have to follow both the law and the Regulator’s Code (set by government) which ensures we treat operators fairly.

What is the Environment Agency doing?

Our focus is to make sure that the site operator, Valencia, takes the right actions to minimise odour. We know that odour is very distressing for people, and it affects all aspects of wellbeing.

We are:

• Increasing our compliance inspection frequency of the site.
• We have worked with the operator to improve their existing management plans for the site (which includes gas, odours and surface water management) so that we do not see a return to the unacceptable odour issues of later 2023 and early 2024.
• We are inspecting new engineering work and existing infrastructure at the site to ensure it is of standard to deal with the permitted site activity.
• We have carried out a 103-day period of monitoring from 10^th May 2024 until 20^th August 2024. The Mobile Monitoring Facility known as an MMF was installed at Our Lady and St Pauls RC Primary School, Sutherland Rd, Heywood, which is near to Pilsworth South Landfill Site. 
• The preliminary report from this study shows that H2S (hydrogen sulphide which is often associated with landfill smells) had no exceedances measured against World Health Organisation health limits.
• The MMF is still in situ and is continuing to measure the air quality and will do so for at least 3 months after the site re opens.

Who else is involved.

The Environment Agency is leading a multi-agency group that has been set up in response to the odours coming from Pilsworth South Landfill Site. The other members of the group are UK Health Security Agency (UKHSA), Bury Council and Rochdale Borough Council.

Reporting Odour

We would like to thank the people who have taken the time to report odours.

This information is instrumental and helps us to build a picture of the extent and impact of the issue.

We encourage residents to continue to report odour to our free 24/7 incident hotline on:

0800 80 70 60

Health related concerns:

We understand that unpleasant strong smells can impact on wellbeing, so we would like to explain more about the effects of odour on health, and what we can do to provide you with further information about this going forwards.

The Environment Agency is working with UKHSA, Bury Council, and Rochdale Borough Council to further understand the impact of the odour issues on your health and wellbeing. We appreciate that this will be concerning, and you will want the problem resolved.

The environmental permits issued by the Environment Agency include conditions that require the operator of the site to ensure they protect the environment and human health. In the case of odour pollution, the operator of the permitted site is required take steps to “prevent or where that is not possible, to minimise odour to a level that is not likely to cause pollution, as perceived by an Environment Agency officer”.

Sites that have the potential to cause odour are required to use appropriate infrastructure, management techniques and abatement equipment to tackle the odour pollution. As the regulator it is our role to robustly challenge the operators of these sites to ensure their systems are fit for purpose and operate effectively.  Where sites are not doing this and we are made aware of odour reports, we will provide advice and guidance, use our enforcement powers or in serious cases, prosecute the operator of the site.

This message has been developed by the Environment Agency, UKHSA, Bury and Rochdale Borough Councils to address heath concerns raised by the community affected by Pilsworth South Landfill Site.

What could I smell late 2023 / early 2024?

The odour pollution from landfill sites falls into two broad categories.

The first is the waste odour, this is caused by fresh waste rapidly decomposing and tends to come from vehicles traveling to and from the site and whilst it is tipped. This is similar to the odours that are contained within a domestic bin. This can be tackled by depositing the waste quickly and covering it with soils called “daily cover”.

The second type of odour is landfill gas. This is gas generated by the breakdown of the waste inside the body of the landfill site. Landfill gas is mostly methane and carbon dioxide, which are odourless and colourless. However, the landfill gas also contains trace components such as hydrogen sulphide that, even in very small quantities, has a strong smell of rotten eggs, which the human body is very sensitive to. Although the smell caused by the trace levels of hydrogen sulphide gas can be strong and unpleasant, it does not automatically mean that it is harmful. Our sense of smell is very sensitive and we can smell hydrogen sulphide at very low levels.

Are the smells causing or going to cause health effects?

The human nose is very sensitive. There are many things that have a strong smell at levels at which there are no direct harmful effects to health. However, strong smells are unpleasant and can impact on wellbeing leading to stress and anxiety. Some people may also experience symptoms, such as nausea, headaches or dizziness, as a reaction to strong smells, even when the substances that cause those smells are themselves not harmful to health.

Short-term transient health effects may be experienced such as irritation to the eyes, nose and throat. People who have health conditions that affect breathing, such as asthma, may experience increased frequency and/or severity of symptoms. With continuing exposure these effects may be prolonged but are not anticipated to continue long-term once exposure is reduced.

Following exposure to any substance, the adverse health effects depend on several factors, including the amount to which you are exposed (dose), the way in which you are exposed, the duration of exposure, the form of the chemical and if you were exposed to any other chemicals. The first noticeable effect of hydrogen sulphide at very low concentrations is its unpleasant odour, which may cause discomfort and some short-term health effects. At higher concentrations it may cause eye, nose and throat irritation. It may also disturb sleep if experienced at night at low levels.

What can I do to reduce symptoms caused by odour?

In order to limit the effects of the odour as much as possible, we would advise:

• Close windows if there is an outdoor odour and open them once any outdoor odour has reduced.
• You could consider closing windows at night and opening them in the morning in the absence of odour.
• Ventilate your property when there is no odour outdoors.
• Contact NHS 111 or your GP if you have concerns about your individual circumstances and require health advice.

Odours can be transient and are more likely to occur overnight and in the early hours of the morning when weather conditions are calm and still. Close windows in the evenings if there is an outdoor odour, and open them in the morning once any outdoor odour has reduced

Recent updates - November 2024

We continue to regulate Pilsworth South Landfill Site in accordance with the environmental permit focussing on engineering works for the construction of new cells along with the assessment of monitoring data and operational plans. We are also still carrying out regular onsite inspections.

The Mobile Monitoring Facility (MMF) remains in situ and is continuing to measure the air quality.

The preliminary results obtained in the 103 day period between 10^th May and 20^th August 2024 indicate that H2S (hydrogen sulphide which is often associated with landfill smells) had no exceedances measured against World Health Organisation health limits.

The full report will be made available when it is ready late November 2024.

We are aware that the site was closed during the monitoring period. The data produced will provide a good baseline for any future data sets that we will monitor in the area.

Odour Pollution Reports

See the table below for a summary of the odour pollution reports received from the public to our National Incident Reporting System (NIRS). The summary is based on their proximity to the Pilsworth South Landfill Site from 1 September 2023 until 31 October 2024.

The Environment Agency has undertaken many recent site inspections at a regular frequency. We were not able to substantiate any odour complaints as part of our recent visits.

FAQ's

What guarantees do the public have that the control of the smell is long-term (i.e. that there won't be significant breaches in the future)

The permit stipulates the level of controls that must be implemented by Valencia for the life of the site. The Environment Agency ensure the permit is being followed and takes appropriate regulatory action where the permit is not being adhered to. 

What enforcement action is being (or will be) taken by Environment Agency against Valencia for the breaches?

The operator is currently subject to an investigation so the details cannot be shared. The enforcement action will follow our enforcement and sanctions policy as found at: Environment Agency enforcement and sanctions policy - GOV.UK (www.gov.uk)

When will the public get to see results from air testing & health advice/info?

We have carried out a 103-day period of monitoring from 10^th May 2024 until 20^th August 2024. The Mobile Monitoring Facility known as an MMF was installed at Our Lady and St Pauls RC Primary School, Sutherland Rd, Heywood, which is near to Pilsworth South Landfill Site. The preliminary report from this study shows that H2S (hydrogen sulphide which is often associated with landfill smells) had no exceedances measured against World Health Organisation health limits.

The MMF is still in situ and is continuing to measure the air quality and will do so for at least 3 months after the site re opens.

We will be able to share the full report from the MMF as soon as it's available around the end of November 2024.

Will the issues of the past 12 months impact on Valencia getting extensions to their licence in the future?

This is purely a decision for the Planning Authority.

What are the longer-term plans for the site?

We have received an application to vary the permit from Valencia. It is to add a recycling centre onto the site to remove metals from waste entering the site in the future. Planning permission has been granted for this activity.

We have a duty under the Environmental Permitting Regulations to consult with the public on new high public interest permit applications, and we want to ensure that we take all relevant information including local information into account as part of our decision-making process.

We also consult other stakeholders who can provide expert advice on the environmental impact of the proposal including the UK Health Security Agency, the Food Standards Agency and the local authority’s Director of Public Health.

The public consultation for this application was open from 25 July 2024 until 23 August 2024.The Environment Agency are currently working through the responses received.

The current planning permission for the landfill site extends until 31^st December 2028. We have required the operator to provide us with comprehensive plans to operate the site within the terms of the Environmental Permit whilst the site is operational.

We have asked the Operator to provide future plans for the site on their agreed public engagement platform to keep communities updated.
