Executive Summary

1. Murphy Environmental (a division of Murphy Concrete Manufacturing Ltd.)

operates an inert waste facility at its site at Sarsfieldstown, Gormanston, Co. Meath. Restoring the site (a sand and gravel pit) will serve to return it in line with pre-quarrying conditions and integrate it into the surrounding landscape.

2. The facility is licensed by the Environmental Protection Agency (EPA) and operates under Waste Licence W0151-01. The licensee (Murphy Environmental) must manage and operate the facility to ensure that the activities do not cause environmental pollution. Murphy Environmental is required to carry out regular environmental monitoring and submit all monitoring results to the EPA.

3. Dust deposition must be monitored at four locations within or around the site on a bi-annual1 basis. Following a an exceedance in the Dust monitoring round for Quarter 2, 2018, carried out between the 2nd May 2018 and the 31st May 2018, a supplementary monitoring round was carried out between the 1st August 2018 and the 31st August 2018.

4. Quarter 2 supplementary, 2018 monitoring results for D1, D3/D3a and D4/D4a/D4b sampling positions were below the emission limit value for dust set in Waste Licence W0151-01.

5. Quarter 2 supplementary, 2018 monitoring results for D2 were not sent to the lab

as there was evidence the bottle had been tampered with. 6. 41 No. dust monitoring rounds (with 4 No. monitoring points per round) have been

completed at the facility under EPA Licence W0151-01, commencing in Quarter 4, 2003. In that time, the EPA licence limit of 350 mg/m2/day has been exceeded on 6 No. occasions only: at D1 during Q3, 2004, Q2, 2007 and Q3, 2007, at D3 in Q2, 2007, and at D2 and D4b in Q2 2018. The overall compliance rate for dust monitoring, since the commencement of dust monitoring at this site, is 96%.

1.0 Introduction

1.1 Background 1.1.1 Murphy Environmental (a division of Murphy Concrete Manufacturing Ltd.)

operates an inert waste facility at its site at Sarsfieldstown, Gormanston, Co. Meath. Restoring the site (a sand and gravel pit) will serve to return it in line with pre-quarrying conditions and integrate it into the surrounding landscape.

1.1.2 The facility is licensed by the Environmental Protection Agency (EPA) and operates

under Waste Licence W0151-01. The licensee (Murphy Environmental) must manage and operate the facility to ensure that the activities do not cause environmental pollution. Murphy Environmental is required to carry out regular environmental monitoring and submit all monitoring results to the EPA.

1.1.3 In accordance with Schedule D of Waste Licence No. W0151-01, Murphy

Environmental is required to carry out dust monitoring on a quarterly basis. EPA correspondence (19/07/2011) subsequently amended the sampling interval for dust to once per annum. The current frequency of dust monitoring is bi-annual2.

1.1.4 This report details the supplementary environmental dust monitoring which took

place in and around the Gormanston site between the 1st August 2018 and the 31st August 2018, including the sampling and analytical methods used. This report also includes an interpretation of the results obtained.

1.2 Dust Particle Size 1.2.1 Dust particle size is important in determining the way in which these particulates

move through the air. When dust particles are released to air they have a tendency to fall back to ground at a rate that is proportional to the particulate size, this effect is known as the settling velocity. Fine dust particles may have the potential to disperse over an extensive area but it is usually the larger particulates that cause most nuisance. The main reason for larger particles being perceived to be a greater nuisance is that: They are more visible to the naked eye

They are the particulates which more readily settle out of suspension

1.2.2 For this reason deposition monitoring for nuisance dusts concentrates mainly on

dust particles of 20 µm diameter and above. 1.3 Monitoring Locations 1.3.1 The dust monitoring locations as prescribed by the Waste Licence W0151-01, are

outlined in Table 1.1 below and illustrated in the attached map, see Figure 1.

D1 North western boundary of the site

D2 Near site entrance – to the southern boundary of the site

D3a* North east boundary of the site, within Zone 5

D4b* West of site

*D3 and D4 were repositioned to D3a and D4a, respectively, in Quarter 3, 2013. This was conducted for access/Health & Safety reasons. In Q2, 2015, monitoring location D4a was moved to D4b, located adjacent to TW-2, for security reasons (dust gauge had previously been knocked over at D4a). The distance between the original and the repositioned locations was minimal. The locations of D3a and D4b are shown in Figure 1.

1.4 Site Activities 1.4.1 To aid in interpretation of monitoring reports, the type and level of activity

operating3 during the period is detailed below. 1.4.2 The W0151-01 licensed tonnes per annum is 750,000; this equates to a licensed

tonnes per month of 62,500. The level of activity on site has been banded as follows: Normal level of activity: Waste acceptance of 45,000 - 65,000 tonnes per

month

High level of activity: Waste acceptance of >65,000 tonnes per month

Low level of activity: Waste acceptance <45,000 tonnes per month

1.4.3 On this basis, the level of activity at the site for the monitoring (and preceding)

period can be categorised as follows:

July 2018: Low level of activity

August 2018: Low level of activity

September 2018: Low level of activity

2.0 Methodology

2.0.1 Dust monitoring for Quarter 2, 2018 was carried out between the 1st August 2018 and the 31st August 2018.

2.0.2 The type of dust deposition gauge used was the Bergerhoff dust gauge which was

exposed over a 30-day period to collect bulk dust deposition (see Plates 1 and 2). The method is based on the German Standard Method VDI 2119 and collects total particulate matter.

2.0.3 The apparatus consists of a collection vessel in the form of a plastic sample bottle,

supported on a stand of approximately 1.5 metres high. The gauges were located at four positions as outlined in Schedule D of Waste Licence W0151-01 (see Section 1.3 and Figure 1, Monitoring Locations Drawing).

2.0.4 The size of the sampling bottle used was recorded, as the diameter of the bottle

impacts on the dust calculation, as per Appendix 4. For calculation purposes, ‘Type A’ sample bottle has a diameter of 8.8 cm; ‘Type B’ sample bottle has a diameter of 9.2 cm.

2.0.5 The gauges were left for a period of 29 days, as per Appendix 1. When the sample period had elapsed the sample bottles were checked for the presence of any unusual deposits such as leaves or insects and these were removed before analysis of the samples took place.

2.0.6 The samples collected were then transferred to Alcontrol Laboratories for

gravimetric analysis to determine the concentration of deposit material in each gauge bottle, as per Appendix 2.

3.0 Results

3.0.1 Results obtained from the laboratory were expressed as total milligrams of dust per sample, for each of the monitoring points (see Appendix 3). Conversion factors were applied to convert laboratory results to milligrams per metre squared per day, based on a 30-day monitoring period (see Appendix 4). Results are listed in Table 3.1 and illustrated in Chart 3.1 below. Table 3.1: Environmental Dust Monitoring Results for Gormanston Landfill (W0151-01) – all results in mg/m2/day Monitoring Location

Monitoring location D4a was moved to D4b, located adjacent to TW-2, for security reasons (dust gauge had previously been knocked over at D4a). The distance between the original and the repositioned locations was minimal. The locations of D3a and D4b are shown in Figure 1.

3.0.2 EPA Waste Licence W0151-01 sets a limit in Schedule C.3 for dust deposition of 350mg/m2/day.

3.0.3 Quarter 2, 2018 monitoring results for D1, D3/D3a and D4/D4a/D4b sampling

positions were below the emission limit value for dust set in Waste Licence W0151-01.

3.0.4 Quarter 2, 2018 monitoring results for D2 were not sent to the lab as there was

evidence the bottle had been tampered with.

4.0 Discussion and Conclusions

4.1 Rainfall Data 4.1.1 Supplementary dust monitoring for Quarter 2, 2018 was conducted between the

1st August 2018 and the 31st August 2018. Rainfall amounts locally for the period are shown graphically in Chart 4.1 below. The total level of rainfall was recorded at 48.2mm, with 11 days recording greater than 1mm of rain and 3 days recording greater than 5mm. The wettest day was 26th August 2018 when a total of 15.6mm of rainfall was recorded.

4.1.2 The 30-year average (1981-2010) gives a mean monthly rainfall of 73.3mm for

August. Rainfall amounts for the monitoring period were, therefore, below average; for this month.

Chart 4.1: Daily rainfall at Dublin Airport during monitoring period

4.2 Interpretation

D1 4.2.1 D1 is located at the north-western boundary of the site and is in close proximity to

the road. The level of dust measured at this point was 25.26 mg/m2/day, which is below the EPA licence limit of 350 mg/m2/day (as per Table 3.1).

D2

4.2.2 D2 is located close to the site entrance, along the southern boundary of the site. Monitoring results for D2 were not sent to the lab as there was evidence the bottle had been tampered with. (as per Table 3.1).

D3a

4.2.3 The level of dust measured at D3a was 149.30 mg/m2/day, which is below the EPA licence limit of 350 mg/m2/day (as per Table 3.1).

D4b 4.2.4 The level of dust measured at this point was 106.34 mg/m2/day, which is below

the EPA licence limit of 350 mg/m2/day (as per Table 3.1).

4.3 Historic Dust Monitoring Results 4.3.1 41 No. dust monitoring rounds (with 4 No. monitoring points per round) have been

completed at the facility under EPA Licence W0151-01, commencing in Quarter 4, 2003. In that time, the EPA licence limit of 350 mg/m2/day has been exceeded on 6 No. occasions only: at D1 during Q3, 2004, Q2, 2007 and Q3, 2007, at D3 in Q2, 2007, and at D2 and D4b in Q2 2018. The overall compliance rate for dust monitoring, since the commencement of dust monitoring at this site, is 96%.

4.4 Conclusion 4.4.1 Quarter 2 supplementary, 2018 monitoring results for D1, D3/D3a and

D4/D4a/D4b sampling positions were below the emission limit value for dust set in Waste Licence W0151-01.

4.4.2 Quarter 2 supplementary, 2018 monitoring results for D2 were not sent to the lab

as there was evidence the bottle had been tampered with. 4.4.3 It is recommended that Murphy Environmental continue to employ the use of dust

control measures in and around the site, e.g. sprinklers, bowsers and road sweepers, as required, especially during prolonged dry periods, and quarterly dust monitoring is continued

CERTIFICATE OF ANALYSIS

SDG: Client Reference:180905-113 MU0122Location: Order Number:



Kerstie

Appendix1. Results are expressed on a dry weight basis (dried at 35ºC) for all soil analyses except for the following: NRA and CEN Leach tests, flash point LOI, pH, ammonium as NH4 by the BRE method, VOC TICs and SVOC TICs.

2. Samples will be run in duplicate upon request, but an additional charge may be incurred.

3. If sufficient sample is received a sub sample will be retained free of charge for 30 days after analysis is completed (e-mailed) for all sample types unless the sample is destroyed on testing. The prepared soil sub sample that is analysed for asbestos will be retained for a period of 6 months after the analysis date. All bulk samples will be retained for a period of 6 months after the analysis date. All samples received and not scheduled will be disposed of one month after the date of receipt unless we are instructed to the contrary. Once the initial period has expired, a storage charge will be applied for each month or part thereof until the client cancels the request for sample storage. ALS reserve the right to charge for samples received and stored but not analysed.

4. With respect to turnaround, we will always endeavour to meet client requirements wherever possible, but turnaround times cannot be absolutely guaranteed due to so many variables beyond our control.

5. We take responsibility for any test performed by sub-contractors (marked with an asterisk). We endeavour to use UKAS/MCERTS Accredited Laboratories, who either complete a quality questionnaire or are audited by ourselves. For some determinands there are no UKAS/MCERTS Accredited Laboratories, in this instance a laboratory with a known track record will be utilised.

6. When requested, the individual sub sample scheduled will be analysed in house for the presence of asbestos fibres and asbestos containing material by our documented in house method TM048 based on HSG 248 (2005), which is accredited to ISO17025. If a specific asbestos fibre type is not found this will be reported as “Not detected”. If no asbestos fibre types are found all will be reported as “Not detected” and the sub sample analysed deemed to be clear of asbestos. If an asbestos fibre type is found it will be reported as detected (for each fibre type found). Testing can be carried out on asbestos positive samples, but, due to Health and Safety considerations, may be replaced by alternative tests or reported as No Determination Possible (NDP). The quantity of asbestos present is not determined unless specifically requested.

7. If no separate volatile sample is supplied by the client, or if a headspace or sediment is present in the volatile sample, the integrity of the data may be compromised. This will be flagged up as an invalid VOC on the test schedule and the result marked as deviating on the test certificate.

8. If appropriate preserved bottles are not received preservation will take place on receipt. However, the integrity of the data may be compromised.

9. NDP - No determination possible due to insufficient/unsuitable sample.

10. Metals in water are performed on a filtered sample, and therefore represent dissolved metals - total metals must be requested separately.

11. Results relate only to the items tested.

12. LoDs (Limit of Detection) for wet tests reported on a dry weight basis are not corrected for moisture content.

13. Surrogate recoveries - Surrogates are added to your sample to monitor recovery of the test requested. A % recovery is reported, results are not corrected for the recovery measured. Typical recoveries for organics tests are 70-130%. Recoveries in soils are affected by organic rich or clay rich matrices. Waters can be affected by remediation fluids or high amounts of sediment. Test results are only ever reported if all of the associated quality checks pass; it is assumed that all recoveries outside of the values above are due to matrix affect.

14. Product analyses - Organic analyses on products can only be semi-quantitative due to the matrix effects and high dilution factorsemployed.

15. Phenols monohydric by HPLC include phenol, cresols (2-Methylphenol, 3-Methylphenol and 4-Methylphenol) and Xylenols (2,3 Dimethylphenol, 2,4 Dimethylphenol, 2,5 Dimethylphenol, 2,6 Dimethylphenol, 3,4 Dimethyphenol, 3,5 Dimethylphenol).

16. Total of 5 speciated phenols by HPLC includes Phenol, 2,3,5-Trimethyl Phenol, 2-Isopropylphenol, Cresols and Xylenols (as detailed in 15).

17. Stones/debris are not routinely removed. We always endeavour to take a representative sub sample from the received sample.

18. In certain circumstances the method detection limit may be elevated due to the sample being outside the calibration range. Other factors that may contribute to this include possible interferences. In both cases the sample would be diluted which would cause the method detection limit to be raised.

19. Mercury results quoted on soils will not include volatile mercury as the analysis is performed on a dried and crushed sample.

20. For leachate preparations other than Zero Headspace Extraction (ZHE) volatile loss may occur.

Identification of Asbestos in Bulk Materials & Soils

The results for identification of asbestos in bulk materials are obtained from supplied bulk materials which have been examined to determine the presence of asbestos fibres using ALS (Hawarden) in-house method of transmitted/polarised light microscopy and central stop dispersion staining, based on HSG 248 (2005).

The results for identification of asbestos in soils are obtained from a homogenised sub sample which has been examined to determine the presence of asbestos fibres using ALS (Hawarden) in-house method of transmitted/polarised light microscopy and central stop dispersion staining, based on HSG 248 (2005).

Visual Estimation Of Fibre Content

Estimation of fibre content is not permitted as part of our UKAS accredited test other than: - Trace - Where only one or two asbestos fibres were identified.

Further guidance on typical asbestos fibre content of manufactured products can be found in HSG 264.

The identification of asbestos containing materials and soils falls within our schedule of tests for which we hold UKAS accreditation, however opinions, interpretations and all other information contained in the report are outside the scope of UKAS accreditation.

Sample Deviations

Asbestos

General21. For the BSEN 12457-3 two batch process to allow the cumulative release to be calculated, the volume of the leachate produced is measured and filtered for all tests. We therefore cannot carry out any unfiltered analysis. The tests affected include volatiles GCFID/GCMS and all subcontracted analysis.

22. We are accredited to MCERTS for sand, clay and loam/topsoil, or any of these materials - whether these are derived from naturally occurring soil profiles, or from fill/made ground, as long as these materials constitute the major part of the sample. Other coarse granular material such as concrete, gravel and brick are not accredited if they comprise the major part of the sample.

23. Analysis and identification of specific compounds using GCFID is by retention time only, and we routinely calibrate and quantify for benzene, toluene, ethylbenzenes and xylenes (BTEX). For total volatiles in the C5-C12 range, the total area of the chromatogram is integrated and expressed as ug/kg or ug/l. Although this analysis is commonly used for the quantification of gasoline range organics (GRO), the system will also detect other compounds such as chlorinated solvents, and this may lead to a falsely high result with respect to hydrocarbons only. It is not possible to specifically identify these non-hydrocarbons, as standards are not routinely run for any other compounds, and for more definitive identification, volatiles by GCMS should be utilised.

24. Tentatively Identified Compounds (TICs) are non-target peaks in VOC and SVOC analysis. All non-target peaks detected with a concentration above the LoD are subjected to a mass spectral library search. Non-target peaks with a library search confidence of >75% are reported based on the best mass spectral library match. When a non-target peak with a library search confidence of <75% is detected it is reported as “mixed hydrocarbons”. Non-target compounds identified from the scan data are semi-quantified relative to one of the deuterated internal standards, under the same chromatographic conditions as the target compounds. This result is reported as a semi-quantitative value and reported as Tentatively Identified Compounds (TICs). TICs are outside the scope of UKAS accreditation and are not moisture corrected.
