The 1996 Waste Management Act provided for local authorities to identify sites within their jurisdictions at which waste disposal or recovery activities had been carried on, to assess any risk of environmental pollution and to identify remedial measures.
As well as municipal landfills, this included unregulated waste disposal sites. However, this requirement was generally not actioned as there was no national standard for the local authorities to follow in assessing risk and in identifying the necessary remediation works. That deficit was addressed in 2007 with the publication by the EPA of a code of practice for environmental risk assessment of unregulated waste disposal sites.
The legal obligations on local authorities for landfills were expanded in 2008.1 In addition to having to register sites they themselves had operated in the period between July 1977 and March 1997 (at which time the EPA became responsible for licensing and regulating landfill operations) and to carry out an environmental risk assessment, local authorities now had to make applications to the EPA for approval and authorisation of any proposed remediation works.
At July 2020, the total number of identified landfill sites was 611.
This included 117 sites licensed and regulated by the EPA since March 1997, and which it continues to monitor — consisting of 64 sites operated by local authorities and 53 operated privately.
494 unregulated sites registered by local authorities on a web-based register established by the EPA.
Over 70% of the sites are former local authority-operated landfills.
Around 21% were privately operated sites, while just over 8% were illegal dump sites.
Landfill sites on the Section 22 register, as at 31 December 2019
The environmental risk assessment of the sites on the Section 22 register involves three progressive stages.
Tier 1 assessment — development of a conceptual site model and risk assessment — this allows for the categorisation of sites into low, moderate and high risk.
Tier 2 assessment — more detailed site investigations and testing.
Tier 3 assessment — refinement of the conceptual site model and completion of a quantitative risk assessment for all moderate and high risk sites.
On completion of the three-tier risk assessment process, local authorities are required to prepare remediation plans to address the risks identified for a site.
Section 22 register number: S22-02296

The site covers an area of 9 ha.
Quantity of waste at facility: Approximately 147,784 tonnes. 106,000 m3
Killycronaghan historic landfill is not owned by Monaghan County Council (landowner is a local farmer)
The site is located almost 7km north-east of Clones on privately owned land and covers an area of 9ha.
The site is surrounded by agricultural lands and is bounded by the Kilgormly river to the
south-east, east and north, and by the Magheramey river to the north-west.
There are poultry houses adjacent to the north-east of the site and three dwellings within 500m of the site boundary, the nearest of which is located 230m from the north-eastern boundary.
The landfill was operational from 1970 to circa 1984 and comprises of approximately 147,784 tonnes of municipal solid waste (MSW).
An appropriate assessment of the activity was carried out as it was determined that there is a hydrological connection between the closed landfill and one SPA site and two SAC sites, the nearest of which is located 16.2km south-west of the closed landfill.
Post remedial works, Monaghan County Council intend to use the site for low intensity grazing.
The risk assessment has categorised the site as High risk (Class A) with high scoring pollutant linkages identified as:
– Leachate migration into groundwater, and, via groundwater, to surface waterbodies;
– Migration of leachate, via groundwater, to Surface Water Body Protected Areas;
– Migration of leachate, via surface water drainage/runoff, to surface water bodies;
– Human health exposure pathway of off-site lateral migration of landfill gas into nearby buildings; and
– Vertical landfill gas migration.
The Technical Commitee notes that the Tier 1 and Tier 2 assessment determined the overall risk score for the closed landfill as high due partly to the risk of migration of landfill gas into the adjacent buildings i.e. the poultry houses, located to the north east, and the farm buildings, situated to the east of the site. The TC further notes that modelling showed that landfill gas will continue to be generated for several years although in minimal quantities. As landfill gas monitoring is carried out in the existing groundwater monitoring boreholes, the TC considers it prudent that monitoring is carried out in the additional boreholes to be installed for groundwater monitoring as required under condition 3.1(i).
The TC notes the high-risk classification of the site is partially due to the risk to the groundwater aquifer from the migration of leachate from the waste body. The TC also notes that the site investigations determined that the groundwater table likely transects the waste body and that groundwater monitoring results show that leachate is having a deleterious effect on groundwater quality.
The site investigations carried out as part of Tier 1, 2 and 3 assessments established the following facts:
– the closed landfill has been capped with soil but the cap allows rainfall to infiltrate into the waste body;
– the landfill is unlined;
– there is migration of landfill leachate into groundwater;
– the landfill is contributing to a deterioration in groundwater quality;
– the waste material is deposited in a single infill area tending west to east in the centre of the site and between approximately 150m in length and 130m in width;
– the average thickness of the waste body is 5m and there is a layer of leachate contaminated sands and gravels below waste;
– the groundwater table appears to be intersecting the waste body;
– leachate seepage was observed near the centre of the site;
– landfill gas is being generated;
– there are two wells present on-site. The Council believes these to be old methane wells;

The Clonbullogue Ash Repository is located approximately 8 km South West of the Town of
Edenderry and 2 km North West of Clonbullogue village. It is located on Cloncreen bog, a cut-away peatland area within the Allen Group of Bogs
Drainage ditches evacuated in the surrounding peatlands by Bord na Mona are orientated in an East – West axis and essentially divert any seepage or drainage water from the peatlands. Drainage from the site is along a West – East drainage ditch which discharges ultimately to the Figile River.
Clonbullogue Ash Repository was to dispose of waste products (fly ash and bottom ash), arising from peat combustion within the boiler of the Edenderry Power Station. Bord na Mona was successful in 2006, in a review process of the facility licence to co-fuel peat with biomass and or meat and bonemeal.
Sligo County Council
Complex historical unregulated landfill site formerly operated by Council
The former landfill covers an area of 13 hectares (ha) on the southern shores of the Garavogue River estuary approximately 1.5km North West of Sligo City Centre.
The former landfill was classified as a high risk site.
Tier 1 Risk Screening, Tier 2 Site Investigation and Testing, Tier 3 CSM (Conceptual Site Model) and Quantitative Risk Assessment (QRA) were completed in accordance with the methodology detailed in the EPA CoP.
Extensive Investigative and monitoring works were completed to provide sufficient information to determine whether linkages existed between the identified source-pathway-receptor linkages including groundwater, surface water, soil, leachate and landfill gas monitoring.
The key risk driver for the former landfill was landfill gas so detailed LFG monitoring and modelling were carried out.
The EPA issued a Certificate of Authorisation to Sligo County Council in 2018. This was the first certificate issued by the EPA for a high risk legacy landfill Site.
SLIGO County Council has published plans for a 4.8 hectare public park on part of the former dump site at Finisklin
Landfill waste (Roscommon Landfill, closed)
Combined sewer overflows
The main pathway in the urban environment will be pipes in the form of primary or secondary discharges from WwTp, Combined Sewer overflows, pumping stations and misconnections.
Hydromorphology (the river has been heavily modified for flood risk)
The CoP follows international best practice and is primarily aimed at providing guidance for historic unregulated waste disposal sites but it shall also be used in relation to illegal landfills.
It is not intended that the CoP be used directly for contaminated land however the general principles may be applied
