4 1. Introduction The client is required to carry out a noise survey at various specified locations in the vicinity of the site in accordance with the terms of its Industrial Emissions licence. This document reports the results of the noise survey. 2. Executive Summary A noise survey to the EPA s NG4 guidance document was undertaken on 9-May 17. A summary of compliance detailing noise levels recorded at each noise boundary for each noise run and comparing these levels with the relevant noise limit values is shown in the table below. It is noted that off-site noise sources contributed significantly to measured noise levels.

7 5. Sampling Methodology 5.1 Instrumentation Used The equipment shown in the table below was used during the noise survey. All Sound Level Meters are Type I. The SLMs and calibrators are identified by a LEN (Laboratory Equipment Number) and this is shown in the table below. Calibration certificates for the equipment, where appropriate, are shown in the appendices and are referenced by the LEN. Table 5-1 Equipment Used Equipment used LEN (Lab equipment Number) Make/Model Serial Number Cal cert First SLM LEN 088 Svantek SV Yes First Calibrator LEN 071 Cirrus Yes Anemometer N/A Kestrel N/A N/A All noise measurements were A weighted and the time-weighting Fast was applied (to equate to human ear hearing). Each SLM is calibrated in the field before the start of the survey and again at the end of the survey. Unless stated otherwise in this report, there was no drift in calibration greater than 0.1 db over the duration of the survey. All SLMs used are capable of third band octave measurement. Third band octave readings were recorded at all locations where tonal noise was subjectively detected by the survey personnel. Where tonal noise was detected, the third band octave readings were analysed off site to verify the presence of tonal. The simplified methodology for the objective identification of tones specified in Annex D of ISO 1996K2:2007(E) is used for this purpose. 5.2 Noise Survey Personnel The noise survey was undertaken by Environmental Efficiency staff as follows: Lead consultant Ronan Sutcliffe, Dip Environmental Protection, IOA Certified Environmental Noise Assessor 5.3 Meteorological Conditions Weather conditions on the day of monitoring were considered appropriate for surveying purposes and therefore did not affect the readings i.e. conditions were dry and wind speed was less than 5 m/s (the normal upper limit for taking measurements). The Sound Level Meter was also fitted with a windshield to minimise interference from potential meteorological conditions, in keeping with good practice. The meteorological conditions during the survey periods are shown below. Environmental Efficiency Page 7 of 25

11 5.5 Ground attenuation If the intervening ground between a noise source and a measurement location is acoustically absorptive, this can result in a reduction in noise level at the receptor due to absorption of sound energy by the ground itself. On the contrary, if the intervening ground is acoustically reflective ground, its products the opposite effect The details of the intervening ground between sources and measurement positions are described in the following table: Table 5-4: Ground attenuation Location % Soft Ground % Hard Ground Comments N No comment N No comment N No comment N No comment Environmental Efficiency Page 11 of 25

12 6. Noise Survey The measurement parameters LAeq,T, LAF90 and LAF10 plus the derived parameter LAr,T are tabulated below in the tables for each monitoring location. Associated particulars such as a description of the on-site noise and off-site noise noticed at each location are also provided where relevant. A graphical representation of the parameters LAeq,T, LAF90 and LAr,T over each monitoring period is provided in the graphs above each table. The derived noise parameter LAr,T, termed the Rated Noise Level, includes a penalty of 5 dba for tonal or impulsive noise where such noise is present. This penalty is normally added to LAeq,T. Where traffic or other off site noise sources are significant, the parameter LAF90 may be a better descriptor of site noise and where this is the case the Rated Noise Level is equal to LAF90 plus the penalty. In the tables below, where LAF90 is considered a better descriptor of site noise, an asterisk is appended to the measurement. The penalty for on-site tonal noise and/or on-site impulsive noise is only applied during the daytime and evening periods. No tonal or impulsive noise is permitted during night-time; if such noise is present then this is a breach regardless of the LAeq,T or LAF90 noise level. Where on site tonal is subjectively heard this is noted in the tables below in the column On site tonal?. In all cases where on-site tonal is heard the simplified methodology for the objective identification of tones specified in Annex D of ISO 1996K2:2007(E) is used to confirm the presence of tonal. Where on site tonal is confirmed, this is shown in the tables below in the column Tonal confirmed. The third octave graphs used to confirm on site tonal are shown in the discussion section. The parameter LAFmax has no bearing on compliance and is not shown in the tables below; however, as it is may be required to be reported separately (e.g. in an Annual Environmental Report) it is included in the appendices. The column headed On site impulsive states whether impulsive noise was heard by the monitoring personnel. Environmental Efficiency Page 12 of 25

21 7. Conclusion The rated noise level at all noise monitoring locations during night-time monitoring exceeded the relevant, prescribed night-time noise limit of 45 db. In addition, the rated noise levels at N4 during day-time monitoring exceeded the relevant, prescribed daytime noise limit of 55 db. The LAF90 noise recorded was determined to be the better descriptor of noise in all instances where there was an exceedance of noise limits as it was determined that intermittent off-site noise sources from traffic on local roads contributed significantly to noise levels. It is noted that off-site noise originating from the operations of an adjacent transportation company situated directly North of the Schloetter facility, in particular truck idling on adjacent roadways, had a signficant effect upon noise readings. It is therefore highly probable that the noise levels causing the exceedance of the emission limit value is not emanating or attributable to the Schlotter site. Locations of truck idling on adjacent roadways are shown in the aerial photo below. Truck Idling Truck Idling Figure 7-1 Overview of truck idling noise sources Environmental Efficiency Page 21 of 25

22 Appendix 1 Report Terminology Survey Run or monitoring run db(a) Noise Monitoring Parameters The measurement of noise over one or more days and is made up of a number of monitoring runs with one or more noise meters. A single measurement at one location to determine noise level. A number of monitoring runs will be typically be made at each location. The duration of a monitoring run is typically 15 or 30 minutes and is stipulated in the licence. This is the unit used to quantify noise measurements. "db" stands for decibel and the "A" indicates that the noise reading is A-weighted and therefore is a measurement of noise audible to the human ear. The scale is logarithmic. L Aeq,T This parameter is measured on-site using a noise meter for a specified time period (T minutes). It represents the average noise level that occurred over that period. Rated Noise Level or L Ar,T L AF10 and L AF90 L AFmax Continuous Impulsive Noise Intermittent Noise Tonal Noise The Rated Noise Level is equal to L Aeq,T plus any penalty for confirmed tonal and/or subjective impulsive. The penalty is only added for daytime and evening monitoring. The L AF10 and L AF900 are both statistical noise levels. L AF10 indicates that for 10% of the monitoring period, the sound levels were greater than the quoted value. L AF90 indicates that for 90% of the monitoring period, the sound levels were greater than the quoted value. The L AF90 indicates the background noise levels if short-term, intermittent noise sources were ignored e.g. a passing car. The L AF10 can be used to determine the effect to which these short-term noise sources effect the overall average reading i.e. if the L AF10 is very different to the L AF90, then intermittent noise is a significant source of noise The maximum RMS A-weighted sound pressure level occurring within a specified time period. Measured using the Fast time weighting. Noise produced without interruption. A noise of short duration (typically less than one second), the sound pressure of which is significantly higher than the background; brief and abrupt. Noise produced on discontinuous basis e.g. equipment operating in cycles or events such as single passing vehicle or aircraft. Noise, which contains a clearly audible, tone i.e. a distinguishable, discrete or continuous note (whine, hum, drone, screech, etc.). Environmental Efficiency Page 22 of 25
