1.0 Introduction and Reporting Period Kerry County Council (KCC) operated a municipal solid waste landfill facility at Muingnaminnane, Kielduff, Tralee, Co. Kerry. It is located approximately 8km northeast of Tralee, in the Stacks Mountains. The landfill site accepted solid waste for disposal and is operated under licence W0001-04. This Annual Environment Report is prepared in accordance with Condition 12.6 and Schedule F of Waste Licence W0001-04. The reporting period for this Annual Environmental Report is from January 1st, 2018 to December 31st, 2018. The acceptance of waste for landfilling and for recycling ceased on site on the 11th July 2014. Both the landfill site and the civic amenity site are now closed to all customers. Kerry County Council is now looking at alternative options for North Kerry Landfill and the Agency will be advised and consulted on the same as this progresses. 2.0 Waste Activities carried out at the Facility Waste disposal activities carried out at North Kerry Landfill were in accordance with Part 1 of Waste Licence W0001-04. Licenced activities include; Class 2 Land treatment, including biodegradation of liquid or sludge discards in soils. Class 4 Surface impoundment, including placement of liquid or sludge discards into pits, ponds or
lagoons. Class 5 Specially engineered landfill, including placement into lined discrete cells which are capped
and isolated from one another and the environment. Class 6 Biological treatment not referred to elsewhere in this Schedule which results in final
compounds or mixtures which are disposed of by means of any activity referred to in paragraphs 1 to 10 of this Schedule.
Class 7 Physico-chemical treatments not referred to elsewhere in this Schedule which results in final
compounds or mixtures which are disposed of by means of any activity referred to in paragraphs 1 to 10 of this Schedule.
Class 11 Blending or mixture prior to submission to any activity referred to in a preceding paragraph of
this Schedule. Class 12 Repackaging prior to submission to any activity referred to in a preceding paragraph of this

6.0 Summary Report on Emissions for the Reporting Period. Emissions to Water. A full report prepared by the Environmental Laboratory of KCC is included in this document in Appendix B. Also included are the Invertebrate Results and Biological Assessment. The verified lab results are also provided in Appendix B. David Lenihan SE Chemist and his team members Caroline Markey, Iona McGloin, Andrew Scanlon and Tim Supple carried out the sampling, testing and reporting for the North Kerry Landfill. Emissions to Air. Gas management practices at North Kerry Landfill are an interlinked system of actions no one of which can fully control or manage the generation of LFG from the deposited waste mass. In combination however, they comply fully with the requirements of the licence. The Systems and operations include:
o Active management of the gas control infrastructure o Odour patrol o Monitoring and testing of infrastructure
The infrastructure in place at North Kerry Landfill includes the construction of a basal liner and capping system. Outside the footprint of the landfill is a network of LFG monitoring boreholes. There are constructed in a grid around the footprint of the area that waste has been deposited within. These wells are monitored on a monthly basis for the presence of a suite of indicator gases that would signal the possible migration of LFG. Perimeter Gas Wells No. 6 through to 6d continues to show CH4 and CO2 concentrations above the allowable limits. These are historically problematic wells. In 2004 wells 6a to 6d were constructed to monitor the gas migration in the vicinity of gas well 6. These perimeter gas wells also showed gas concentration levels in excess of the allowable at times during the year. It is noted however that there is no odour nuisance at the location of gas wells 6 through to 6d or any evidence of vegetation die back. The likely cause was due to historical contamination issues. The perimeter Gas Wells 6, 6a to 6d were constructed on a man-made embankment. Perimeter gas well 6 is currently connected to the gas extraction system and is under a low negative pressure. In November 2011, the gas to energy project was successfully commissioned. A Genset of nominal rating -330 kW is in operation at the facility. The demand of the generation plant has been balanced against the generation output of the field. Field balancing and network management are vital components of a successful operation of the gas to energy project. These are actively managed by B9 to ensure maximum production. Over the last 12 to 18 months, gas production has reduced considerably. B9 Power Ltd have operated the engine continuously throughout the year. In relation to the flare downtime, B9 Power Ltd has been only operating the engine due to the reduced quantity of landfill gas produced on site, as shown on the SCADA graphs over the last year. In accordance with the licence condition 3.15.3, 'landfill gas shall be utilised as an energy resource where feasible and possible as maybe agreed by the Agency' which is why the engine takes preference to the flare. The engine is only operating at part load due to the limited gas available and there is insufficient gas to operate the gas flare. This was noted to the EPA on previous discussions and in particular at the site visit SV14537 and the Gas and Leachate Management Report 2018 under licence return LR034773.

B9 Power Ltd and KCC have been proactive in trying to identify any potential issues and ways of increasing gas production/recovery over the last couple of years. As shown in the Gas & leachate Management Report 2018, KCC installed 9 no. additional gas wells and have carried out remedial works but with limited improvement to gas yields. Furthermore, KCC are currently carrying out works to dewater a number of wells. On an annual basis, KCC procure competent odour consultants to check for fugitive emissions. Odour Monitoring Ireland Ltd carried out such surveys in the past at the request of the EPA and in 2018, when the gas abstraction was on in accordance with best practice, there were no fugitive emissions highlighted. This showed that KCC could continue with the gas engine (Capacity at 400m3/hr @ 26% CH4) as the gas engine has more than enough capacity to deal with actual flows. The gas levels on the SCADA monitor is as follows recorded in early Jan 2019:
The integrity of the gas infrastructure is very good as illustrated by the constant suctions recorded across the site (i.e. no pressure drops caused by condensate blockages in the pipework) & the low oxygen levels. However, the quality of methane produced is very low and this has been the case for a while but B9 Power Ltd continues to balance the gas extraction system on a frequent basis to optimise the gas where possible. To prove that gas production has been reducing over the last while, KCC procured Fehily Timoney & Co to look at the gas model and update it. This is included in Appendix C Gas Balancing records, Landfill Gas Survey, Engine Stack Monitoring are included in are Appendices: D, E, and F.

7.0 Resource and Energy Consumption. The following is the energy consumption for North Kerry Landfill for the reporting period. Diesel The diesel usage for the reporting period (1st January to 31st December 2018) was 276 litres. This is a significant decrease in diesel of 551 litres from the previous reported year (827 litres). Electricity The total usage for 2018 was 70,750 kWh. This is a significant decrease in energy consumption of 5,400 kWh. This is primarily due to the installation of the SCADA system and more prudent management of resources. 8.0 Energy Efficiency and Audit Report Summary Electricity The kW hour usage on site for 2018 is set out in the attached table.

These figures were used in the estimation of landfill gas generation over the reporting period and submitted as part of the Landfill Gas Survey 2018 (Appendix E) and the PRTR 2018 (Appendix G) online Kerry County Council engaged Fehily Timoney & Co to carry a review of the Gas Model in Dec 2018. The development of Gas Predication model for future PRTR estimates that historical landfill gas prediction modelling for the landfill significantly overestimated the potential generation of landfill gas. This over-estimation when referenced to utilisation and flaring flow rates suggested that there were significant fugitive emissions escaping from the waste body. This is not the case as evidenced by:
• VOC emission survey results • No odour issues • No evidence of vegetation die-back
B9 Power Ltd. has a financial incentive to capture landfill gas for utilisation. The audit findings in 2018 suggest that the gas that is being produced is being utilised by the gas engine. FTC believes that gas production flow rates on the site will be similar to current flow rates and will most likely remain low for many years. As leachate drains and is removed following secondary consolidation of the waste, breakdown of the waste body will be initiated in what were leachate saturated pockets and gas production is likely to continue for many years albeit at lower gas production rates. The graphs below presents a range of indicative gas production curve of future gas production flow rates. The calibration is based on existing available information

20.0 Summary of Procedures Developed by the Licensee during the reporting period No additional procedures were developed by the Licensee during the reporting period. 21.0 Tank, Pipeline and Bund Testing and Inspection Report Integrity testing was completed on leachate lagoons 1 and 2 in 2016. Integrity testing is to be carried out every 3 years as per Waste Licence Conditions. It is due again for re-testing in 2019. 22.0 Environmental Incidents and Complaints Environmental Incidents The incidents reported to the agency refer to exceedances experienced in perimeter gas wells 6 to 6d and PGDW E9. It is noted that there were no odour nuisances in the perimeter gas well exceedances or no vegetative die back and so it is thought that the readings in gas well 6 to 6d refer to a sump effect in a rock fill embankment that is at a finished construction height above the original ground level. Well 6 is currently connected to the gas extraction system and this is noted in the monthly returns to the Agency. Complaints There were no complaints received for the reporting period (2018). There were none in 2017, 2016, 2015, 1 in 2014 and 10 in 2013 Table 18.1: Breakdown of complaints received over last five years

24.0 Report on Financial Provision Kerry County Council has a Landfill Aftercare and Development Fund. The CRAMP report as submitted to the agency and approved in March 2015 requires the Kerry County Council to maintain the landfill site both during its active phase and closed phase. A review by Kerry County Council was completed in Dec 2016 and submitted to the Agency for approval. Kerry County Council is well positioned to meet its financial liabilities. The EPA have corresponded with the Local Authorities to make financial provisions to cover any liabilities associated with the operation (including closure and aftercare) of the facility, as per Condition 13.3.3. Kerry County Council have submitted licensee returns to deal with these liabilities.

26.0 Programme of Public Information The site has been closed since 11th July 2014. Therefore, all relevant files are available on site for the Agency’s inspection 27.0 Training of Staff 2018 The Landfill Manager is up to date with regards to training in SAFEPASS, First Aid and Fire Marshalling. The site manager completed all remaining waste management modules in 2018. The Landfill Manager has completed the Waste Management Training Programme Module 1 to 6 28.0 Cost of Landfill / Community Fund.
Please see Condition 13.5 of Waste Licence referenced W000 1-04 The licensee shall provide the sum of €57,419 per annum (index linked) for local environmental and community initiatives for each year that the landfill accepts waste for disposal. A report on the use of this annual fund shall be included in the Annual Environmental Report to the Agency. The Community Fund is operated under the Local Government Act 2001 – Section 109 – (1) In this section "community initiative" means any project or programme which in the opinion of the local authority will benefit the local community and includes the provision or improvement of amenity, recreational, cultural or heritage facilities, the protection or enhancement of the environment and programmes to promote social inclusion and community development. As no waste was accepted at North Kerry Landfill in 2017, Kerry County Council did not allocate any money to the Community Fund. There is a balance of approximately €50,000 remaining in the Community Fund. Kerry County Council, Environment Section has been in contact with community leaders & asked them to submit a viable community initiative project (or projects), for consideration. The Environmental Management Team have met with the Landfill Committee to discuss possible projects in 2018.

Sathorlann CCC North Kerry Landfill: AER Report 2018: Laboratory Monitoring 26th Mar 2019 KCC Laboratory
David Lenihan 2 of 18
In 2018 a total of 286 samples were sampled by KCC Laboratory personnel compared to 200 in 2017. The extra samples were due mainly to further research projects. Altogether 2000 tests were analysed to satisfy requirements of licence monitoring. Of these 1980 tests were analysed in KCC laboratory. The outsourced tests were analysed by ELS laboratories. The latter included Cyanide and List1 / 2 organics as required on an annual basis for three groundwater locations It must however be stressed that each test for SVOCs or VOCs comprises analysis for 153 specific compounds. These are included as appendix to this report The monitoring locations monitored are as per requirements of licence. APP1 outlines locations and associated northing’s and easting’s Trigger limits Trigger limits are required to be set for certain parameters in groundwater and submitted to EPA. Perhaps the best such limits to use are groundwater threshold values as set out in groundwater regulations 2009. Other standards used, correspond to drinking water regulatory standards. However, where drinking water limits cannot be adhered to because of natural conditions (non-anthropogenic effects) i.e. Ph the trigger value would have to be more flexible. The trigger values for Boreholes 1 to 4 are as highlighted in Table 1. Borehole 5 appears to be monitoring an aquifer which contains a lot of decaying organic matter more than likely from natural sources. Table I Parametric Trigger values for Groundwater Parameter units Trigger value ( max) Trigger value(min) Ammonium mg/L 0.225 Nitrite mg/L 0.38 Total Oxidised Nitrogen mg/L
Pesticides2,3 ug/L 0.375 1 PAHs neasured should include at least benzo(b)Fluoranthene, benzo(k Fluoranthene, benzo(ghi)perylene,indeno(123-cd)pyrene Fluoranthene 2 the trigger value applies to each individual pesticide measured. 3Pesticides include organic insecticides, Organic herbicides, Organic nematocides, organic acaricides, organic algicides, organic rodenticides, organic slimicides, related products (inter alia, growth regulators
List 1 and List 2 Organics Under the provisions of monitoring requirements, we are required to monitor List 1 and List 2 organic compounds in three groundwater locations on an annual basis. These locations have to be agreed with EPA. In this report we report on four groundwater locations which were monitored for these compounds i.e. Borehole 4, GWML-E3, GWML-E1 and Sugrues well (well on adjoining property to Landfill) The compounds analysed comprised of two types Volatile Organic compounds (VOCs) and Semi Volatile organic compounds (SVOCs). VOCs comprise of organic compounds with boiling points close to or less than that of Water i.e. Petroleum products and common solvents –up to 79 compounds were screened for using Purge and Trap GC MS. Semi Volatile compounds comprise of higher boiling point organics and comprise of classes of compounds such as pesticides, herbicides, PCBs (polychlorinated Biphenyls) and PAHs (Poly aromatic Hydrocarbons). Up to 63 different compounds in this category were screened for. A list of these compounds, together with limits of detection is given in Appendix 2. Original report from contract laboratory is also enclosed
All parameters analysed were below their respective detection limits Heavy Metals As we possess and use *ICP-MS instrument we monitored many more locations for heavy metals than were strictly required i.e. 14 surface water, 6 Leachate, and 8 groundwater locations *Inductively coupled Plasma Mass spectrometer

INTERPRETATION OF RESULTS Groundwater
All boreholes are showing evidence of surface water contamination to a greater or lesser extent – borehole 2 been least affected. This is evident from turbidity colour and Total Organic carbon levels. The source of this surface water contamination is undoubtedly exacerbated by rainfall. There was evidence of some contamination in in Borehole 2 in November judging by higher than normal Ammonia and phosphate concentrations but latest results from Feb indicate a return to background levels. Borehole 4 had also momentary spike in ammonia levels in Feb after very heavy rainfall Borehole 5 exhibits evidence of presence of substantial Iron pan judging by high Iron, manganese and even Arsenic results which is a natural occurrence from the bedrock on site. There is stagnant water at borehole 5 and this has shown a rise in ammonia in 2018. Due to a suspected collapse in the borehole, it is not possible to purge the well and it proposed to either remediate the area or install a new well. These works will take place in 2019 Fig 1 Ammonia levels in Borehole 5 between 2014 and 2018
Boreholes GWML E1 and E3, 4 and Sugrues well were tested for list 1, 2 organics. No organic compounds were detected above their respective detection limits Surface water: Impact of Suspended solids: Results from monitoring over last 10 years indicates that most significant threat or impact from Landfill activities in surrounding waters is suspended solids. Samples were obtained “in site monitoring” from Stations SWML 1, 2, 3, 4, 5, 10, 11 and new lagoon SWMLE1. Suspended solids have declined significantly since 2014 at on-site surface water lagoons (SWMLE1) and SWML 10 in Nov. Figs 4 and 7. No significant levels of Suspended solids were noted.

In the case of surrounding sites spikes of suspended solids appear occasionally during or after heavy rain. However, in general levels of suspended matter are low There were some suspended solids noted in samples taken in February and November corresponding to high bursts of rainfall High suspended solids in river waters may impair fish spawning grounds particularly in winter and spring. Occasional pulses of suspended matter entering these sites are more than likely the main contributory factor for unsatisfactory biological quality in the past. In the case of O’ Brennan’s bridge it was agreed following unsatisfactory result in 2017 that biological monitoring would be undertaken twice i.e. May and September. The May 2018 result was favorable i.e. Q 4-5. However, by September 2018 this value had deteriorated to 3-4 All other impact sites monitored i.e. E1, N1, G1, G2 Note deterioration in site E2 from Q4 to Q 3 See summary of Biological report in APP 3 An example of suspended solids impact is shown in Fig 2
Impact of Ammonia levels on receiving waters No significant levels of ammonia were recorded in period 2014 to 2018 unlike in 2013, where up to Nov 2013 significant levels were recorded in new lagoon SWML E1 Leachate results There was a low leachate detection in detection manholes monitored LD1 and LD2 but it is negligible by the time it enters LD3

Subject: Biological Assessment of impact sites at North Kerry landfill. Date: September 2018 Introduction: Under the EPA License granted to North Kerry Landfill at Muingnaminnane surface waters draining the landfill are continually monitored. Condition 9.9 of the license requires biological assessment to be carried out annually. Seven sites are included for assessment as follows: W1, W2, E1, E2, G1, G2 and N1 (See Map app a). Biological Q Rating: The samples were classified using the Biological Quality Rating System for Rivers (Q Rating System) as outlined by the Environmental Protection Agency (EPA). The Biological Quality Rating System for Rivers (Q ratings) ranges from Q1 to Q5 where a Q5 denotes a pristine river and Q1 indicates serious pollution (see Quality Rating Table below). From the point of view of the Water Framework Directive all rivers and streams must be at least Good status i.e. Q4. High status river stations are not allowed to deteriorate. There are different classifications for depositing and eroding substrates. The Q system is aimed particularly at larger streams and rivers and is carried out between May and September. Three-minute kick samples are carried out at each station accompanied by stone examinations and weed sweeps.

Table 2: Chemical Results
Discussion: W1 biological station drains the western side of North Kerry Landfill. It is a very small stream just downstream of the landfill and a tributary of the river Lee. The terrain is very steep, the stream is very narrow and the water flows over a series of small falls. When last sampled. In September 2014 this site was found to be inaccessible due to (i) A new high wire fence with barbed wire on top running the length of the stream. (ii) Trees and bushes cut down and allowed to fall over the stream. The situation remains the same in September 2018.Therefore this station could not be sampled. W2: NKL Biological station W2 is at O’Brennan’s Bridge on the River Lee approximately 3km downstream of W1. It drains the Western side of the landfill including many of the surface water drains. This Station was sampled twice in 2018. May 2018: In May this site merits a Q value of 4-5 denoting very good quality and a high WFD quality status. Four A group species were found in numerous abundance. Group C is abundant but mainly due to Baetis rhodani with low numbers and good diversity of other Group C species. The tolerant Group D and E are absent and scarce respectively.

September 2018: In September this site merited a Q rating of 3-4 denoting a WFD quality status of “Moderate” and “slightly polluted” water quality. The reasonably good representation of Group A (two species in fair numbers) is offset by the abundance rating of “Superabundant /Excessive” for Group C. This is mainly due to the numbers of Simuliidae and Baetis rhodani present. Simuliidae make up 60% of Group C. This is a significant dominance. There is an overall decrease in Group A from 33% in May to 6% in September and an increase in Group C from 51% to 79% in the same period. Group D and E are scarce and absent respectively. E1 biological station is a small stream draining the Eastern side of the landfill. It runs through bog land. It merits a Q4-5 indicating very good water quality and a High WFD Quality status. There are four Group A species in an abundance category of “Numerous/Abundance”. Group C are represented by six species with low numbers of each and the tolerant Group D and E are absent. This site is of very high-quality veering on the high side of the Q4-5. E2 biological station also drains the Eastern side of the landfill. It is a tributary of the Smearlagh River. It obtains a Q3 indicating a poor WFD Quality status. Group A is absent. There is low diversity with 64% of the species present being made up of Baetis rhodani (33%) and Simuliidae (31%) both of which belong to Group C. The pH at this site is acidic at 5.3 and invertebrate abundance tends to be lower for the entire community at pH values less than 6. Group A Ephemeroptera (Mayfly) species are one of the most sensitive groups of aquatic insects to low pH, Plecoptera (Stoneflies) and Trichoptera (Caddisflies) are generally less sensitive. The high iron reading of 1678ug/l found at E2 combined with the low pH may contribute to the low diversity and density found here. G1 The Glashoreag River drains the Northern side of the landfill. G1 biological station is on the Glashoreag River upstream of the Northern stream confluence. It scores a Q4-5 rating which indicates very good quality and a “High” WFD quality status. Four A group species were found in “Numerous” abundance. The more tolerant and diverse C group are abundant in numbers but mainly due to Baetis rhodani and the tolerant D and E groups are absent. These factors are significant in its rating. N1 biological station is situated on a small stream which drains forestry on the northern side of the landfill. For the purposes of this report it will be referred to as the Northern Stream. It is a tributary of the Glashoreag River, its confluence lying between biological stations G1 and G2. It scores a biological Q rating of 4-5 indicating very good water quality and a high WFD quality status. Two Group A species in “Common/Numerous” abundance, Group C abundant with good diversity and a total absence of Groups D and E were found. G2 biological station is located on the Glashoreag River downstream of the N1 confluence. Access is through private land densely planted with trees with a heavy overgrown ditch at the access point to the river. It has always been a difficult site to access but has become inaccessible due to increased growth in the last four years. Due to this it could not be

sampled in 2016, 2017 or this year 2018. It was decided in 2016 to sample further downstream at Ivy Bridge. Ivy Bridge: The Glashoreag River at Ivy Bridge is further downstream of G2 and upstream of the confluence with the River Smearlagh. It scores a biological Q rating of 4-5 indicating very good water quality and a high WFD quality status. Three Group A species in “Numerous” abundance coupled with a good spread of low numbers in the more diverse Group C and the total absence of Group D and E are indicative of the high score obtained.

PROJECT: North Kerry Landfill FILEC:\Users\DAVID~1.DON\AppData\Local\Temp\p1820%20north%20kerry%20gas%20model%20review%20rev%202%2018%20dec%20208.xls-1.xlsm
The model make no allowance for waste compositions that differ from average US conditions. Adjustments are therefore required if waste composition of the subject landfill differs from US historical averages. This calibration tool is not suited to residual waste where organic content of the waste may be very low.
The model applies a best fit result for the target date and only selects the five closest curves to that date. The selection does not by default represent the most appropriate curve.
Users when entering flow data must make allowance for fugitive emissions.
The gas prediction tool uses spreadsheets developed by the US Environmental Protection Agency. The manual and software of LandGEM version 3.02 can be obtained from the following web addresses respectively:
Attached is an example of a typical audit report generated by the FTC as balancing software tool
Thereafter the five curves that provide the closest match to the gas extraction flow rate observation at the specified audit date (Table 1.3) are selected and presented graphically in Figure 1.1.
These graphs (Figure 1.1) present prediction model outputs against audit flow records and allow inputs also from one other prediction curve (GasSim or other).
Thereafter the best fit curve from the 5 generated LandGEM curves can be selected (Table 1.7) and the k and Lo values determined for the best fit curve.
The algorithms used to develop the spreadsheet are documented in Ref 2.
The model requires representative audit results over an extended period and on the basis of such produces a best fit curve using LandGEM algorithms.
This landfill gas calibration tool is one of a suite of programs developed by FTC designed to facilitate balancing of landfill gas extraction.This tool was developed because historical audits of sites invariably show significant differences between audit results and the theoretical gas prediction curve developed for the facility.This software tool is designed as a validation check when using theoretical gas prediction models. Following inputs of MSW waste and historical gas extraction audit results, algorithms develop a locus of curves using the LandGEM software for respective k and Lo selections.

1.5 Database calculations
Ref 5
This Landfill Gas Review should not be used for Pollutant Release & Transfer Policy (PRTR) as data was provided only from the months of January to September.The results from the Landfill Gas Review will not comply with the (PRTR) annual report for 2018, which is an EPA requirement for all licenced facilities.
The best fit curve for the Year 2015 is Model 5 (illustrated with a purple line) in the LandGEM Landfill Gas Prediction Model. The associated Model data is attached in "8.1E LandGem Model 5" and give an estimate of gas predictions to facilitate PRTR returns
The purpose of the landfill gas review is to update the gas prediction model with the use of historical has flow rate records.
Kerry County Council provided Gas Audits for 2016, 2017 & 2018. Each Gas Audit contained monthly data on the well monitoring of gas extraction at North Kerry.
For the purpose of the gas review, all monthly values of the historical landfill gas flow rate were tabularised and averaged to find an average yearly value that could be inputted into the model. See Appendix 1.
For the purpose of the gas review, all monthly values of the methane content were tabularised and averaged to find an average yearly value that could be inputted into the model. See Appendix 2.
The gas prediction model was trialed with the values of historical landfill gas flow and methane percentage for the years 2015, 2016, 2017 and 2018 following the instructions of LandGEM Calibration Curve. The best-fit prediction curve was selected.
The curves are created using waste inputs and different factors for k and Lo. These calculations are carried out in the background but if the user wishes to view them they can be unhidden.
Some worksheets are also password protected to prevent inadvertent errors with macros, should the user want to unprotect them the password is 1234
2.0. Landfill Gas Review
Rev 2 flows in 2017 and 2018 were normalised to 50% as advised by Ref 5 email and the model calibration was conducted for 50% methane.
The year 2015 generates the five gas flow prediction curves that represent the best fit of the North Kerry landfill when compared to the values of 2016, 2017 and 2018.

Select best-fit prediction curve from Fig.1.1 and enter best fit in Table 1.7. This model number curve will be used for PV analysis.9. Table 1.8 allows manual selection of k and Lo.NOTE Default year settings on x axis of Fig 1.1. If dates outside these years are required reformatting of the axis is required
IMPORTANT NOTE:This model is only accurate for methane concentrations between 40 and 60 percent. UsingLandGEM at landfills that have methane content outside the range of 40 to 60 percent is notrecommended. The first-order decomposition rate equation used by LandGEM to determineemissions may not be valid outside of this range.Note also that LandGEM uses waste stream composition based on average of US sites

Gas quality is holding but suction is increasing gradually,
when barometric pressure increases it puts pressure on
the gasfield
Comments: Gasfield is being over extractedPoor gas recovery - extremely difficult to utilse the poor gas yield & operating the engine in reduced methanogenesis activity.

A survey of landfill sites to determine the quantity of methane flared and or recovered in utilisation plants for 2018
Please choose from the drop down menu the license number for your site
Please choose from the drop down menu the name of the landfill site
Please enter the number of flares operational at your site in 2018
Please enter the number of engines operational at your site in 2018
Once completed please send the completed file as an attachment clearly stating the name and or license number of the landfill site (e.g. W000 Xanadu landfill_2018) to:
Please note that the closing date for reciept of completed surveys is 31/03/2019
The Office of Environmental Sustainability (OES) of the Environmental Protection Agency acts as the inventory agency in Ireland with responsibility for compiling and reporting national greenhouse gas
inventories to the European Commission and the United Nations Framework Convention on Climate Change. In addition to meeting international commitments Ireland’s national greenhouse gas
inventory informs national agencies and Government departments as they face the challenge to curb emissions and meet Ireland’s emission reduction targets under the Effort Sharing Decision (No.
406/2009/EC). The national inventory also informs data suppliers, making them aware of the importance of their contributions to the inventory process and a means of identifying areas where input data
may be improved.
It is on this basis that the Environmental Protection Agency is asking landfill operators to partake in this survey so that the most uptodate information on methane flaring and recovery in utilisation plants
at landfills sites is used in calculating the contribution of the landfill sector to national greenhouse gas emissions
The Environmental Protection Agency wishes to thank you for partaking in this survey. If you have any questions about the survey and how to complete it please view the "Help sheet" worksheet. If
however, your query is not answered by viewing the "Help sheet" worksheet please contact:

This 2018 assessment is in accordance with Condition 8.11.1 of the EPA waste licence issued to the site (Current IED Licence No: W0001-04)
1.2 Site Description
The facility is situated in north County Kerry, approximately 11 km west of the town of Tralee in the townland of Muingnaminnane.
The site was developed as a municipal landfill facility and recycling centre. The site ceased receiving waste for deposition in 2014. Kerry County Council is currently undertaking various works associated with the sites aftercare.
Kerry County Council’s Chartered Engineer completed a site walkover of the site on 18th May 2018 to examine the existing landfill slopes at North Kerry Landfill. All slopes within the site were inspected as part of the visual assessment with written and photographic notes taken. Slopes were inspected on foot generally traversing from toe to crest across the entire length of the slope.
The heavy growth of vegetation and grass was cut back during Q4 2017 and Q1 2018 where the landfill cap at Cells 1 – 19 were flailed. Long grasses, scrubland and rushes with some trees and larger bushes were cut back. Re-profiling and installation of drainage within the landfill cap across Cells 1 to 16 to shed runoff was completed in Q1 2018 which has substantially reduced surcharge loading.
No visibly unstable slopes were observed on the site and no tension cracks were observed in any of the slopes which may have suggested potential instability.
1.3 Previous Slope Stability Assessments A previous slope stability assessment for the landfill was undertaken during March 2017. The reported issues noted during this visual assessment in 2017 have since been completed as outlined below:
1. Vegetation growth on slopes to be cut back and maintained such that more effective visual
inspections can be completed on the landfill slopes for future annual inspections as required by the conditions attached to IED Licence No. W0001-04.
2. Re-profiling and installation of drainage within the landfill cap across Cells 1 to 16 to shed
runoff, improve trafficability and reduce surcharge loading. The localised depressions noted across the capping may have been caused by settlement following waste degradation or additional surcharge loading caused by the waterlogging of the capping material.
Where areas are noticeably waterlogged waste below the liner may also be saturated in the event that the cap liner has been compromised. If materials above the cap liner remain saturated there is an increased risk of a translational failures. If the waste is saturated there is an increased risk of a rotational failure within the waste body as any tension cracks that develop become water filled allowing water ingress deeper into the slope.

1.4 Site Walkover Kerry County Council completed a site walkover of the site on the 18th May 2018. All slopes within the site were inspected as part of the visual assessment with written and photographic notes taken. Slopes were inspected on foot generally traversing from toe to crest across the entire length of the slope.
All slopes were assessed for signs of instability or identification of potential factors which may impact the future stability of the landfill slopes.
A Site Layout Plan is included in Appendix 1 to this document.

2 CONDITIONS OF SURVEY
The condition survey completed was limited to a visual inspection of the exposed elements of the landfill slopes only and limited to readily accessible areas. The purpose of the condition survey was to assess and advise of issues relating to the stability of the landfill slopes as required by Waste License W0001-04 (IED).
No intrusive investigations or prolonged monitoring of defective areas were carried out by Kerry County Council. No structural analyses, testing or measurements were undertaken when compiling this report. This report reflects Kerry County Councils interpretation of the site condition from a visual inspection only.

3 SLOPE STABILITY OBSERVATIONS
3.1 CELLS 17, 18 and 19
Cells 17, 18 and 19 are shown in the Appendix 1: Site Layout Plan. These cells are the most recently filled and capped cells.
The main slopes were observed to be vegetated by grass.

3.2 CELLS 1 to 16
Cells 1 to 16, the oldest in the landfill, are shown in Appendix A: Site Layout Plan. All cells in this area have been capped. The slopes to cells 1 to 16 vary in steepness from 1:1 to 1:10 approximately. The slopes were vegetated with scrubland and rushes which have been cut back and maintained in Q4 2017 and Q1 2018 making it easier to transverse through the capping.
The slopes are considered to be stable.

Section 4 Kerry County Council North Kerry Landfill: Slope Stability Assessment
4 SUMMARY AND CONCLUSIONS
Kerry County Council completed a site walkover and visual slope stability assessment of North Kerry Landfill on the 18th May 2018.All slopes were walked in a toe to crest survey, photographed and examined for indications of instability.
The results of this visual assessment indicate that the landfill body main slopes are generally considered to be stable. Reprofiling of a small section of the service track along Cell 17 (Side slope to access road) at the South West slope (to the rear of site office) is to be completed by the end of 2018. Kerry County Council will ensure that:
1. Reprofiling of a small section of the service track along Cell 17 (Side slope to access road) at the South West slope (to the rear of site office).
2. The vegetation growth on the slopes must be flailed and maintained every 2 years which will ensure
effective visual inspections are completed on the landfill slopes as required by the conditions attached to IED Licence No. W0001-04.As such any hidden hazards such as gas well enclosures below ground level (which may be hidden by vegetation) are identified.
3. Maintenance of the recently constructed drainage system within the landfill caps which help runoff,
improve trafficability and reduce surcharge loading.
