Executive Summary

- 1 -

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-annual basis. Dust monitoring for Quarter 3, 2018 was conducted between the 4th September 2018 and the 4th October 2018.

4. Quarter 3, 2018 monitoring results for D1, D2, D3/D3a, and D4/D4a/D4b sampling positions were below the emission limit value for dust set in Waste Licence W0151-01.

5. 42 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 at Q3 2007, at D2 in Q2 2018, at D3 in Q2 2007, and at D4a in Q2 2018. The overall compliance rate for dust monitoring, since the commencement of dust monitoring at this site, is 98%.

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-annual1.

1.1.4 This report details the environmental dust monitoring which took place in and

around the Gormanston site during Quarter 3, 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

operating2 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 3, 2018 was carried out between the 4th September 2018 and the 4th October 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; ‘Type C’ sample bottle has a diameter of 7.5 cm; ‘Type D’ sample bottle has a diameter of 10.3 cm.

2.0.5 The gauges were left for a period of 30 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

*D3 and D4 were repositioned to D3a and D4a, respectively, in Quarter 3, 2013. This was conducted for access/Health & Safety reasons. 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 3, 2018 monitoring results for D1, D2, D3/D3a, and D4/D4a/D4b sampling

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

4.0 Discussion and Conclusions

4.1 Rainfall Data 4.1.1 Dust monitoring for Quarter 3, 2018 was conducted between the 4th September

2018 and the 4th October 2018. Rainfall amounts locally for the period are shown graphically in Chart 4.1 below. The total level of rainfall was recorded at 47.7 mm, with 9 days recording greater than 1 mm of rain and 3 days recording greater than 5 mm. The wettest day was 20th September 2018 when a total of 15.7 mm of rainfall was recorded.

4.1.2 The 30-year average (1981-2010) gives a mean monthly rainfall of 59.5 mm for

September and 79 mm for October. Rainfall amounts for the monitoring period were, therefore, significantly below average.

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 57.16 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. The level of dust measured at this point was 93.17 mg/m2/day, which is below the EPA licence limit of 350 mg/m2/day (as per Table 3.1).

D3a

4.2.3 The level of dust measured at D3a was 331.73 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 42.22 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 42 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 at Q3 2007, at D2 in Q2 2018, at D3 in Q2 2007, and at D4a in Q2 2018. The overall compliance rate for dust monitoring, since the commencement of dust monitoring at this site, is 98%.

4.4 Conclusion 4.4.1 The dust levels recorded during this monitoring period at the Murphy

Environmental Gormanston facility at sampling locations D1, D2, D3/D3a, and D4/D4a/D4b were deemed to be in compliance with the EPA licence W0151-01 limit of 350 mg/m2/day.

4.4.2 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:181009-100 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 factors

employed.

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.
