3 1. Introduction Ambient Dust levels were measured at KMK Metals Recycling Ltd, Cappincur Industrial Estate, Daingean Road, Tullamore, Co Offaly from the 02 nd June to the 30 th June 2016 by Q.E.D. Engineering Ltd, as part of the company s Waste Licence No. W , Schedule C.6. A total of four locations were set up for the annual dust monitoring. A map showing the ambient dust monitoring locations is provided in Appendix 1. All monitoring locations were defined in the licence W in Schedule C Methodology and Instrumentation Ambient dust monitoring was carried out by Anthony Meehan, BSc in Environmental Science & Technology, of Q.E.D Engineering Limited, using the following method; Standard method VDI 2119 (Measurement of Dustfall, Determination of Dustfall using Bergerhoff Instrument (Standard Method) German Engineering Institute). Prior to going on-site, the collecting pots and lids were cleaned thoroughly with DECON 90 cleaning solution and rinsed with distilled water. The lids were then placed on the pots and the site name and date were marked onto the pots. The Bergerhoff dust gauges were set up on the site on the 02 nd of June Four gauges were put in place, in the following locations; Ref. No. Location A2-1 E yard at wall of northern boundary A2-2 Eastern boundary inside wall A2-3 Fence at southern boundary A2-4 Fence at western boundary The Bergerhoff dust gauges were left at the site for 28 days and removed on 30 th of June Met data for the period of monitoring was obtained from Gurteen Agri College, 42km distant, from Met Eireann data. The collection pots were sent to BHP Laboratory for analysis. The determination of total dust precipitation was calculated following the stages stipulated in VDI Inorganic Dust Deposition analysis was carried out on dust pot A2-3 due to significant algae growth in the pot. Results are compared to a limit value of 350mg/m2/day, as stipulated in licence W in Schedule C.6. 2 EPA Export :15:29:51

4 3. Results The total dust precipitation obtained at each location is provided in Table 1.0 and the results for metal content in the same samples is provided in Table 2.0. The laboratory report is included in Appendix 2. Visual observations on collection of dust pots are noted in Appendix 3 along with photos of the dust pots on the day of collection. Details of weather conditions during the monitoring period are provided in Appendix 4, which show that there were 9 days with no rain during the monitoring period and 5 days with <1mm of rain. The average wind strength was 6.78 knots which based on the Beaufort Scale of Wind Force could be classified as a wind force of 3 (Gentle Breeze) i.e. leaves and small twigs in constant movement. In addition, there were 17 recorded wind speeds greater than average for the period. The June 2016 Met Eireann summary report showed that all monthly mean air temperatures were above their Long-Term Average (LTA). Over three-quarters of stations reported it was their warmest June in six or seven years. Rainfall was variable across the country. Occasional heavy showers in places lead to variable percentage of LTA rainfall values being recorded. Gurteen weather station which is located 42km from the site showed above average rainfall with a percentage of Long Term Average value of 132%. The monthly mean wind speeds ranged from 4.6 Knots (8.5km/h) at Mullingar, Co. Westmeath, to 11.3 knots (20.1km/h) at Mace Head, Co. Galway. Weather conditions can have a noticeable impact upon dust creation and dust entrainment in the air. Rain falling on the site will dampen down dust generated and drier weather will increase the ambient dust on the ground and will lighten small particles. Wind strength will determine the size of particles that can be entrained in the air and the distance they can be transported. 3 EPA Export :15:29:51

6 4. Discussion Dust monitoring was carried out between the 02 nd of June and the 30 th of June The period of monitoring was a typical operational month at the site, with unsettled wind conditions and above average temperatures and rainfall, when compared to Long Term Average s. These climatic conditions were favourable for dust creation and movement. From the results of dust monitoring conducted in June 2016, all four dust monitoring locations at KMK Metals Recycling Ltd. were below the EPA limit value of 350 mg/m3/day. Inorganic Dust Deposition analysis was carried out on dust pot A2-3 due to significant algae growth in the pot as can be seen in the photos in Appendix 3. Dust monitoring location A2-3 has always shown low results due to its positioning at the rear of the WEEE building on the southern boundary. The highest result recorded was at dust monitoring location A2-1, which is situated in the E yard area on the northern boundary adjacent to the car park. Previous dust monitoring at the site has also resulted in the highest levels being recorded at this location. The E yard area sees a significant amount of HGV traffic as vehicles weigh-out over the weighbridge through the yard. The yard is also used for skip drop off and collection and by forklifts when transporting WEEE components to storage areas. This regular movement of vehicles rises dust which otherwise is not obviously noticeable on the yard. The site keeps the E yard area in a tidy state and the yard is swept frequently to maintain a clear thoroughfare for vehicles. In addition, the predominant wind direction in the area is from the south west, which will blow dust in the direction of dust monitoring location A2-1. An analysis of the metal content in the four dust deposition samples was also carried out. There are no Emission Limit Values specified for the metals content in the licence. Results of metal sampling show that all metals in the dust samples collected are relatively low. Results for all samples are broadly similar. 5

7 5. Conclusion Dust monitoring was carried out at KMK Metals Recycling Ltd. between the 02 nd of June and the 30 th of June All four dust monitoring locations at KMK Metals Recycling Ltd. were below the EPA limit value of 350 mg/m3/day. The highest result recorded was at dust monitoring location A2-1, which is situated in the E yard area on the northern boundary adjacent to the car park. This location sees a significant amount of traffic and skip drop offs and the transporting of WEEE components to storage areas. 6
