Spending Review 2022: Landfill Remediation Grant Scheme

Feb 2023

Available Data and Data Limitations

All of the available performance and financial data of this scheme, was provided for the completion of this report.
This is managed through the national steering group for the programme which was established in 2019. The steering group, which is chaired by DECC, meets quarterly and allows for both the allocation and re-allocation of funding in response to project progress and allows for standardised data collection on project progress for every site in receipt of funding, annually.

Site data includes the following variables

Site ID, remediation status, risk rating (if available), site type, region, local authority/payee, project name, amount in euro (nominal terms), purpose of payment, source of funds (Vote or EF), year incurred, invoice date, subhead, and additional notes

Note submitted from DECC to PAC on Landfill Remediation Programme

Further details of the 494 sites in the landfill remediation programme to include their location, what are the outstanding issues, and what actions are being taken to minimise costs being borne by the State

The Regional Waste Management Plans are being updated and consolidated with a view to publishing a single National Waste Management Plan for a Circular Economy in Q1 2023. This will set out the renewed roadmap for delivery of the national policy for the landfill remediation grant programme for the next 7 years.

Attached at Appendix I is a spreadsheet which provides the current position on the status of all 494 sites.

The term ‘commenced’, as referenced in Appendix I, has been used to broadly include sites where local authorities have sought funding under the grant programme e.g., some level of works has commenced; ‘authorised’ means sites now regulated under the Waste Management Act (as amended), 1996; and ‘resolved’ means sites addressed by local authorities without drawdown of grant funding and no further works are envisioned.

2019 Anti-Dumping Initiative:

Kildare County Council Silliot Hill, Private/illegal dump (remediated historic landfill, Euro 6.42m costs)

Kildare Kerdiffstown, Illegal dump (not on closed landfill register, €14m costs – Kerdiffstown was a licensed site which invoked waste enforcement intervention due to operating outside of its licensing conditions)

Coolock/Darndale landfill remediation programme. Large scale illegal dumping site on a green space between the R139 road and a
residential area in Moatview, Darndale. Managed via National Waste Enforcement Steering Committee (NWESC). Enforcement actions at the site have included the prosecution of individuals under the Waste Management Act and the revocation of the waste collection permit of a local resident. Specialist Environmental Consultants have been engaged by DCC to undertake Environmental Assessments to gauge both the scale and type of waste involved and to advise on the subsequent means and level of clean up required.

John Ronan & Sons

Dudley’s Mills, Clonmel, Tipperary

P0225-01 Tipperary

Inspections cover Bawnard Landfill and associated discharge locations, general site conditions, lagoon liner and perimeter

Historic plant for Tanning and Fellmongering, plus related landfill

John Ronan & Sons group operated a small landfill (c.1ha) which is located c.4km east of the factory site. This site which is included in the IPC application is leased from a farmer. The only wastes accepted, aside from restoration and road maintenance inert fill, were from the tannery. Some 3000t tonnes per annum were placed in the site. This comprises c.2000t solid waste (trimmings, sweepings, waste wool, hooves, horns, and similar), and c.1000t sludge from the waste water treatment plant.

Crag Arklow Limited

P0031-02 Wicklow

The licence transfer request (Ref. LT00196) for the licence to be transferred to Crag Arklow Limited was accepted by the EPA on the 4th August 2021.

Surface water emission point previously at site (EFF1) is no longer operational. There were no aqueous discharges to the Avoca River in 2021. Biannual-monitoring of onsite surface water monitoring points continued

A Quantitative Risk Assessment and Natural Monitored Attenuation Programme for the site was submitted and accepted by the EPA in 2012. This includes biannual monitoring completed on stormwater, groundwater and leachate to confirm the natural attenuation of the legacy pollutant plumes at the site.

The licensee changed its name in 2017 from Holfeld Plastics Ltd. to Avoca River Park Ltd.

Inagh Landfill

W0109-02 Clare

Ballyduff Beg, Inagh, Clare

The site is a closed landfill site with an operational bring centre

Tank 1 is a covered lagoon area that stores collected surface water runoff from the main site yard and green waste processing area. Tank 2 is an above ground storage tank containing a combination of leachate collected from the main landfill body via the leachate collection and pumping system and overflow water from Tank 1.

All water within Tank 1 is transferred to Tank 2 before being transported off site for treatment at the Clare Co. Co. Wastewater Treatment Plant

Ballymurtagh Historic Landfill, Wicklow

Waste Licence: W0011-02

Ballymurtagh Landfill closed for waste acceptance in 2002. The capping of the landfill was complete in 2006. It is located on a previously used open cast copper mines. Today, the landfill is on aftercare and a small recycling centre operates adjacent to the landfill

There have been no complaints arising from the activities at Ballymurtagh for over 20 years.

Groundwater Pollutants Identified:
Copper, Lead, Nickel, Sulphate & Ammonia.

The landfill is located in the area of the old Avoca Mines. Groundwater in the entire area shows excessively high levels of metals, which are detected in the quarterly analysis. At one location, Ammonia from the landfill leachate discharge is also detected. This level has been demonstrated to be decreasing over time.

EPA agreed financial provision is in place. CRAMP & ELRA last agreed by the Agency in 2017

The annual slope stability assessment was last undertaken in 2016. The most recent slope stability assessment report submitted to the Agency was on 03/12/2013 (ref. LR006371). This is a Non- Compliance with Condition 6.17.

The topographical survey for 2021 was not undertaken at the site. This is a Non-Compliance with Condition 6.18. It is noted that a topographical survey for 2022 has been partially undertaken at the site in 2022 in response to the landfill cap breach (ref. INCI022640).

Actions Required:

Comply with Conditions 6.17 & 6.18. With regard to the 2016 slope stability assessment, the Licensee shalloutline how and when the recommendations outlined in the report were implemented.

The Licensee shall ensure all future slope stability assessments shall investigate the slope integrity at bothsurface and subsurface levels.

The landfill gas collection infrastructure has not been maintained and is not fit for purpose – pipelines have sagged and become blocked with condensate and/or disconnected from the flare. This has resulted in a 50% loss of the landfill gas collection network, low volumes of landfill gas reaching the flare, higher volumes of oxygen being drawn into the gas field and difficulties in balancing the gas field and maintaining the run- time of the flare.

This is a Non-Compliance with Condition 3.6

On occasion the flare has been used to drain the pipework of leachate, which poses a risk of over-drawing the gas field and pulling oxygen into the gas collection network.

There are two functioning leachate wells at the site – Condition 6.15.2 requires five wells to be maintained at the site.

This is a Non-Compliance with Conditions 6.15.1 & 6.15.2.

The landfill gas collection system was disconnected from the enclosed landfill gas flare and connected to a low calorific high temperature open flare in 2020.

This was done in the absence of assessing the performance of the landfill gas collection network, and despite the Licensee being aware of issues in the network.

The Licensee failed to submit a Specified Engineering Works (SEW) proposal and obtain the written approval of the Agency prior to undertaking these works. This is a Non-Compliance with Conditions 1.4 and 3.3.1.

While the low calorific high temperature flare is being operated at temperatures around 1,020oC, the Licensee could not confirm the burn chamber residence time during the site visit, to demonstrate compliance with Condition 6.16.3.

The Licensee has undertaken one landfill cap performance assessment report since the licence was granted. The Licensee is required to undertake a landfill cap performance assessment once every three years and report to the Agency on each occasion. The Licensee has not submitted this report to the Agency in three years prior to 31/12/2021.

This is a Non-Compliance with Condition 6.20.

Monitoring of leachate levels is required to be undertaken monthly. Licensee return LR065199 shows the Licensee is undertaking this monitoring on a quarterly basis.

This is a Non-Compliance with Condition 6.1 & Schedule C.3.

Landfill gas balancing records are maintained on a monthly basis. However additional balancing undertaken more frequently at a smaller number of wells is not recorded.

The quality of balancing records does not allow for the interrogation of actions taken during the balancing exercise i.e. the balancing sheets do not record the:

• Existing state of the valve at the wellhead (for example, closed, 10% open, 100% open);
• Changes made to the valve during the balancing event;
• Gas concentrations prior to making changes and after making changes (if applicable);
• Any observations made during the balancing exercise, such as infrastructure repairs needed, condensate draining needed/undertaken, issues/odours noted/addressed

While it is noted the site is visited daily by Council staff, the flare is not connected to an out of hours call out/alarm system.

This is a Non-Compliance with Condition 6.1 & Schedule C.1.1.

The annual VOC monitoring was not undertaken at the landfill in 2021.

Surface water drainage and infrastructure used to divert surface water away from the landfill waste body has not been maintained – these include the:

• Surface water drains and swales (which were not sufficient to divert surface water away from the cap, evident by the cap being wet underfoot, rushes growing and swales had long grass growing in them);
• Landfill cap depressions (allowing ponding of water on the cap); and
• Surface water retention pond (which was overgrown and inaccessible, and fencing around the pond was damaged).

The failure to maintain surface profiles, water collection drainage infrastructure and the storm water retention pond at the site is a Non-Compliance with Conditions 3.17 & 10.4.1.

The failure to demonstrate the integrity of the surface water retention pond is in Non-Compliance with Condition 6.9.

T.E. Labs monitor surface water, groundwater and leachate.

In compliance with Condition 6 of Waste Licence W0011-02, Wicklow County Council is required to carry out environmental monitoring at Ballymurtagh Landfill at such locations and frequencies as set out in Schedule C: Control & Monitoring of the licence.

Schedule C.5 details the requirements for the monitoring of receiving water, Schedule C.4 details the requirements of groundwater monitoring and C.3 the leachate monitoring.

Quarterly reports are submitted in line with the requirements set out in the licence.

Groundwater in the immediate area of the landfill and beyond is heavily polluted from the workings associated with Avoca mines. Specifically, extremely high levels of metals and resulting conductivity are observed along with low pH.

The groundwater-monitoring programme includes monitoring wells:
 Twin Shafts
 G1/04
 G1/05
 G2/05
 RC6
 SW3 (Ballymurtagh Road Adit)
and at five private wells.

Current landfill gas collection infrastructure on the facility

There is a total of 42 vertical wells and 2 pumped condensate knock out pots on the facility. Horizontal and Vertical landfill gas abstraction is employed in the facility. There is one operational installed landfill gas enclosed flare (500 m3/hr).

Leachate Monitoring:

TelLab undertake leachate monitoring on a quarterly basis. Leachate analysis is undertaken at all wells that are not dry.
