FAQs (previous)

What is the current status of the site?

The landfill and waste facility at Kerdiffstown has closed and is now undergoing the early stages of a clean-up or ‘remediation’ process. The Environmental Protection Agency (EPA) is using powers under the Waste Management Acts to clean the site and put in place appropriate aftercare measures to prevent and limit pollution from the materials on the site.

The facility at Kerdiffstown was operated by Neiphin Trading Limited under a waste licence issued by the EPA. The site consisted of an extensive recycling facility, now mostly dismantled, an authorised lined landfill which had been partially filled with waste and a large area in which substantial quantities of waste have been deposited.  There are also smaller quantities of waste stockpiled around the site.  The presence of such large quantities of waste and the lack of appropriate infrastructure to manage polluting emissions gives rise to the risk of environmental pollution.

What is the EPA doing to get this site cleaned up?

The EPA has undertaken enforcement proceedings (including three High Court cases) against those involved in the operation of this facility.  High Court orders are now in place preventing Neiphin Trading Limited depositing any further waste onto the Kerdiffstown Landfill site.  Orders were made by the High Court in 2010 requiring three companies previously involved in the site to clean it up.  This has not happened to date and the Agency has now begun to take measures to prevent and limit pollution from the materials on the site.   The holders of the waste remain responsible for this waste and we will continue to pursue the viable legal sanctions open to the Agency, in line with our enforcement policy, to recover public money.  Works already completed as part of the measures by the EPA to limit and prevent pollution include;

  • A team of security personnel on the site 24-hours a day.
  • Vulnerable access points to the site have been fenced and vehicle access points have been blocked off.
  • Immediate health and safety issues have been addressed; unsafe lengths of litter netting have been taken down; known excavations and pits have been filled; and two large, unsafe buildings on the site have been enclosed with fencing.
  • Wastes that posed an imminent risk of further fire and consequential pollution, such as the large stockpile of mixed plastic wastes and a stockpile of tyres, have been removed from the site.
  • Liquid leachate, a potential pollutant, continues to be removed from the landfill cell at the site.
  • Landfill gas wells have been installed in preparation for pipe work and landfill gas flares being installed in the coming weeks.

Planned works over the coming weeks:

  • Installation of pipelines to capture the landfill gas and pipe it to landfill gas flares, where it will be treated in a controlled manner to reduce the polluting nature and odour of the gas.
  • Commence the tender process for the detailed site investigation works and a specialist consultant to carry out the detailed design of the overall remediation of the site.
  • Continuation of health and safety works as necessary, to make the site a safe place to work for EPA and contractor personnel. This will include works to make safe damaged buildings on the site.
  • Maintenance of security and fencing at the site. Security surveillance requirements will be reviewed as required.
  • Continuation of environmental monitoring of air, water and groundwater. Results from this monitoring will be made available online to the public.
  • Setting up a community liaison group and establishing a dedicated project website. As mentioned above, the EPA is committed to an open communication policy on the remediation project.

What are the risks from this Site?

When waste is in a landfill it decomposes to produce a mixture of gas called landfill gas.  This gas consists primarily of carbon dioxide and methane but also contains trace amounts of other gases which have a pungent odour.  Landfill gas at the Kerdiffstown landfill is not being collected and treated to reduce its impact and as a result the gas is venting to atmosphere causing nuisance odours around the site.  Some components of landfill gas can be harmful at high concentrations and if they accumulate in confined spaces.  

As rainwater falls on the site it drains through the waste and becomes contaminated.  This contaminated liquid is called leachate and it is escaping into the ground and groundwater beneath the site.    

The EPA is continuing to monitor the air, the groundwater and the surface water around the site to assess the risk from landfill gas and leachate and to detect any pollution arising. The risk will remain until such time as the site is cleaned up and remediated.

Are houses near the site at risk from landfill gas?

A risk assessment recently undertaken by international experts identified that, because there is no cover on the landfill, there is currently a low risk of landfill gas migrating via the ground into off-site buildings.  However, the gas is escaping upwards into the atmosphere and causing odour.  The EPA has been testing for landfill gas ground migration at the installed monitoring wells since June 2010.  The results to date do not indicate a current cause for concern with respect to landfill gas migration via the ground at this time.

During the works to install gas collection wells, a number of gas migration wells were also installed around the site.

What can be done about the smell?

This site contains a large amount of waste which continues to produce odorous landfill gas. The waste is stored without adequate landfill gas management and control, as is required by current landfill regulations. The planned works described above will help reduce some of the odour. However, odour may continue to be encountered until full remediation is completed - and in particular during work phases where wastes will be disturbed. A priority for this project will be to minimise, as far as is practicable, the level of nuisance associated with this site.

What are the impacts on water?

The EPA employed international experts to carry out an environmental risk assessment of the site on our behalf.  This study allowed us to find out where leachate is entering groundwater and to track the direction and progress of any polluted groundwater.  Because of our concerns about the efficacy of existing monitoring wells, the EPA has installed ten groundwater and landfill gas monitoring wells around the site.  These wells are located in areas identified by geophysics techniques as being at the greatest potential risk.

Groundwater contaminated with leachate has been identified along the eastern boundary of the site.  The surface watercourses closest to the site include the ‘canal feeder’ channel, the Grand Canal and the River Morell.  EPA monitoring is concentrating on the River Morell as it was identified as being at the greatest potential risk from the migration of contaminated groundwater from the site.  Monitoring of the River Morell does not indicate an actual impact of concern at the moment, but the potential for a future impact to the river remains.  Kildare County Council is also monitoring the river regularly.

What is the EPA’s role in securing the site?

The site has been secured by the EPA for the duration of the remediation project. Full remediation will take a number of years. It is not planned that the site will be used again as a commercial landfill.

Where can I get access to information on the site?

The results of monitoring conducted by the EPA at this site from May 2010 will be made available on our website and on public file in the EPA’s Regional Inspectorate at McCumiskey House, Richview, Clonskeagh Road, Dublin 14, open during normal office hours.  The EPA’s reference number for the site licence is W0047-02.
