Monaghan. The assessment has been updated in response to Further Information Item 1(a), which requires consideration of the existing background noise environment and the proposed increase in noise arising from the development. This fi nal Further Information assessment incorporates the clarified operational scope, including the enclosed Debris Reception Building, the JC Environmental-only waste stream, the 2,000 tonnes per annum intake limit, the recycler vehicle process, the revised operating hours and the updated biofilter/odour-control unit design basis. Construction and operational noise impacts are assessed at the nearest noise-sensitive receptors, with operational industrial/commercial sound assessed having regard to the principles of BS 4142:2014+A1:2019. 1.2 Site Description The proposed development is located at Mullanarry on the south-western outskirts of Carrickmacross, Co. Monaghan. The surrounding receiving environment comprises a mixture of residential, commercial, industrial and agricultural land uses. Residential properties in the vicinity are treated as high-sensitivity noise receptors. The local and regional road network and existing commercial/industrial activities contribute to the prevailing acoustic environment. 1.3 Existing Use The application site is occupied and operated by JC Environmental, which provides drainage and environmental contracting services. Existing activities include vehicle and tanker movements, vehicle parking, loading and unloading, movement of plant and equipment, and vehicle/equipment cleaning. Baseline monitoring identified road traffic as the dominant source within the local acoustic environment, with existing JC Environmental truck and tanker movements and occasional clattering/banging also audible. The measured baseline therefore represents the existing receiving environment with current site activities in operation. 1.4 Proposed Development The proposed development has been revised as part of the Further Information response. The existing machinery shed/bays will no longer be used for waste reception, unloading, screening or other waste-processing activities. No change of use of an existing machinery-shed bay to waste processing is therefore proposed under the revised development. All routine waste reception, unloading, secondary/final screening and associated waste-handling operations will instead take place within the dedicated enclosed Debris Reception Building, which has a floor area of approximately 192 m². The proposed development also includes the associated biofilter/odour-control system, controlled extraction system, covered/underground wastewater-storage infrastructure, structure associated with the existing wastewater tanks, concrete apron and associated ancillary site-development works. The site will be used solely for material arising from JC Environmental's own gully, drain and sewer-cleaning activities, and no third-party waste will be accepted. Specialist recycler/vacuum tanker vehicles undertake the majority of liquid/solid separation and water recovery before returning to the site. Material returned to Mullanarry therefore principally comprises residual grit, screenings, sediment and debris together with a limited residual liquid fraction. The maximum annual intake will be limited to 2,000 tonnes per annum. All routine unloading and secondary/final screening will take place within the enclosed Debris Reception Building. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 6 1.5 Potential Impacts Noise from the proposed development has the potential to impact surrounding existing residential receptors during the construction and operational phases. This Noise Impact Assessment has addressed noise in relation to the construction and operational phases. 1.5.1 Construction Phase Construction noise will arise principally from construction and fit-out works associated with the enclosed Debris Reception Building, installation of the biofilter/odour-control equipment, works associated with the covered tank area and concrete apron, and associated ancillary works. Temporary construction vehicle and plant movements have the potential to affect nearby noise-sensitive receptors and are therefore assessed on a conservative basis. 1.5.2 Operational Phase Most liquid/solid separation is completed within the recycler vehicle during the off-site gully and drain-cleaning operation. On-site activity is therefore limited to controlled unloading of the residual material, secondary/final screening where required, short-term contained storage and onward transfer. The following activities have been identified as the principal operational noise sources: • JC Environmental recycler/vacuum tanker arrival, departure and on-site manoeuvring; • controlled unloading of residual gully and drain-cleaning material within the enclosed Debris Reception Building; • secondary/final screening of residual grit, sediment and debris within the building; • transfer of the limited residual liquid fraction to the covered/underground storage system; • process and transfer pumps; • the proposed biofilter/odour control unit (OCU) extraction fan and associated mechanical equipment; • vehicle and equipment washing; and • other ancillary activities associated with normal operation of the facility.

Stage 1: Initial Process The development is categorised according to whether it has the potential to generate noise i.e. a Noise Generating Development (NGD) or be affected by the existing noise i.e. a Noise Sensitive Development (NSD). All Noise Sensitive Receptors (NSRs) that have the potential to be impacted by the proposed development are identified and prioritised according to their level of sensitivity. Residential NSRs are noted to be of high sensitivity. Stage 2: Quantitative Assessment The quantitative assessment method depends on the type of development proposed i.e. Noise Sensitive Development (NSD) or Noise Generating Development (NGD). Typically, the assessment will compare absolute levels (predicted or measured) with an agreed target. The magnitude of the impact is then defined by assessing the amount the predicted noise level exceeds the agreed assessment target criteria for either day or nighttime periods. The agreed target and magnitude of impact scales used in this assessment are presented in Section 3. Stage 3: Qualitative Assessment The qualitative assessment allows the magnitude of the impact established in Stage 2 to be adjusted accordingly to account for additional factors not addressed in the quantitative assessment. Stage 4: Level of Significance The level of significance of the noise impact at the NSR is obtained through the relationship of the receptor’s sensitivity to noise and the magnitude of the noise impact. The prescribed level of significance is used to determine whether or not noise is a key decision-making issue for the NSR in question. Stage 5: The Decision Process Stages 2 to 4 are repeated for all identified NSRs, and a Summary Table of Significance is completed which provides an overview of the level of significance of the noise impact on all NSRs. 2.2 Calculation of Road Traffic Noise Sound PLAN Version 9.0 noise modelling software has been used which is based on the Department of Transport Calculation of Road Traffic Noise (CoRTN) and ISO 9613 noise propagation methodology. 2.3 World Health Organization Guidelines for Community Noise In Guidelines for Community Noise, 55 dB LAeq,16h is indicated as a criterion threshold below which few people are seriously annoyed for an outdoor living area, during daytime and evening hours. A lower guideline value of 50 dB LAeq,16h is provided as a criterion below which few people are annoyed. In addition, the guidance identifies that negative sleep impacts are avoided at 30 dB LAeq,8h for continuous noise sources. It is stated that “for a good sleep, it is believed that indoor sound pressure levels should not exceed approximately 45 dB LAmax more than 10 – 15 times per night”. It should be noted that these limits are typically understood to relate to the onset of adverse impact. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 8 2.4 BS5228-1:2009+A1:2014; Code of Practice for Noise and Vibration Control on Construction and Open Sites. Methods for calculating noise and vibration produced by construction and open sites are provided in BS5228- 1:2009+A1:2014. Annexes C and D of Part 1 provide generic source data for different types of noise source, as well as methods for calculating noise from stationary and mobile plant. 2.5 BS 4142:2014+A1:2019, Methods for rating and assessing industrial and commercial sound. BS 4142:2014+A1:2019 provides methods for rating and assessing sound of an industrial and/or commercial nature, which includes: a) Sound from industrial and manufacturing processes. b) Sounds from fixed installations which comprise mechanical and electrical plant and equipment. c) Sound from loading and unloading goods and materials at industrial and/or commercial premises; and d) Sound from mobile plants and vehicles is an intrinsic part of the overall sound emanating from premises or processes, such as that from forklift and truck movements in or around an industrial and/or commercial site. The methods described use outdoor sound levels to assess the likely effects of sound on people who might be inside or outside a dwelling or premises used for residential purposes upon which sound is incident. The measured specific sound source is corrected for acoustic features (if present) of intermittency, impulsivity, and tonality to give the rated noise level. The assessment considers the impact of the specific sound by subtracting the measured background sound level from the rating level and considering the following. a) Typically, the greater this difference, the greater the magnitude of impact. b) A difference of around +10dB or more is likely to be an indication of a significant adverse impact, depending on the context. c) A difference of around +5dB(A) is likely to be an indication of an adverse impact, depending on the context. d) The lower the rating level is relative to the measured background sound level, the less likely it is that the specific sound source will have an adverse impact, or a significant adverse impact. 2.6 Monaghan County Council Development Plan The Monaghan County Development Plan 2025 - 2031 currently in place has been considered in this Noise Impact Assessment. “8.11 Noise 8.11 Noise The impact of noise pollution is an important consideration in assessing all development proposals as it can impact on people’s quality of life and health. The Environmental Noise Regulations 2018 (as amended 2021) give reference to the EU Directive 2002/49/EC relating to the assessment and management of noise pollution. A Noise Action Plan is in place by the Council for major roads within County Monaghan carrying more than 3,000,000 vehicles per year. Using the provisions of the development management process, the Planning Authority will aim to take account of and mitigate noise and/or vibration at site boundaries or adjacent to noise sensitive locations, in particular residential properties with reference to layout, design and/or noise attenuation measures. Consideration also needs to be given to avoid adverse impacts when introducing noise sensitive uses in proximity to existing and future national roads. Where warranted, proposals should include mitigation and should have regard to Section 3.7 of the DECLG Spatial Planning and National Roads Guidelines (2012). Noise Objectives NO 1 To promote the implementation of the Noise Directive 2002/49/EC and associated Environmental Noise Regulations 2006. NO2 To ensure development design considers noise alleviation measures, were appropriate, to reduce noise and vibration impacts on surrounding amenities, particularly residential amenity and other noise sensitive locations (e.g., places of worship, healthcare facilities). REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 9 3.0 METHODOLOGY AND TARGET CRITERIA 3.1 Methodology The noise assessment was undertaken to establish the impact of construction and operational activities on noise sensitive receptors surrounding the Site. The assessment involved the following stages. • Long-term baseline noise monitoring was undertaken at NML1 to characterise the existing daytime and night- time acoustic environment. The monitoring location was selected having regard to its position within the appli- cation site and the influence of existing road traffic and commercial/industrial activity. The measured baseline is used to establish representative existing ambient and background sound levels for the operational assessment. • Review of proposed construction activities, locations, and noise data. • Calculation and assessment of construction noise at the most exposed sensitive receptors, following guidance provided in BS5228-1:2009+A1:2-014; Code of Practice for Noise and Vibration on Construction and Open Sites. Computer noise modelling using Sound plan software has been used in the calculation of construction noise at sensitive receptors. • Review of proposed operational activities, plant locations, duty cycles and source noise data, including recy- cler/vacuum tanker movements, controlled residual-material unloading, secondary/final screening within the enclosed building, process/transfer pumps, the OCU fan and vehicle/equipment washing. • Prediction of operational noise using Sound plan V9.0 software at locations of exposed sensitive receptors; and • Assessment of operational noise, using principles defined in BS4142:2014. 3.2 Construction Noise Assessment Methodology and Target Criteria 3.2.1 BS5228-1:2009+A1: 2014 – Methodology (ABC Method) The assessment of construction noise is conducted in accordance with guidance provided in BS 5228-1:2009+A1:2014 ‘Code of Practice for Noise and Vibration Control on Construction and Open Sites – Part 1 Noise’. The standard describes methods for evaluating the potential significant effects of construction noise, one of which is the ‘ABC’ method which is based on exceedance of fixed noise limits. The ABC method, as detailed within Annex E.3.2 has been used within this noise assessment, as it considers the pre-existing industrial noise climate at the receptors. The ABC method considers that a potential significant effect occurs when the total noise level at a dwelling, including construction activity, exceeds the appropriate category values shown in Table 1. The table is used as follows. • The ambient noise is determined and rounded to the nearest 5dB. • The rounded ambient noise level is then compared with the total noise level, including construction. A significant effect at a noise sensitive receptor is considered to occur when the total noise, including construction activity exceeds the appropriate category values, shown in Table 1. • The ABC method of BS5228-1:2009+A1:2014 does not provide specific guidance on determining the magnitude and significance of noise impacts above the threshold values shown in Table 1. In order to determine the level of significance, guidance provided in the • The significance criteria adopted within this noise assessment are shown in Table 2. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 10 Table 1: Threshold of Significant Effect at Dwellings Period Category A Category B Category C Night-time (23:00 to 07:00) 45 50 55 Evenings weekday (19:00-23:00), Saturdays (13:00-23:00) and Sundays (07:00-23:00) 55 60 65 Daytime weekday (07:00-19:00) and Saturdays (07:00-13:00) 65 70 75 Note 1: A significant effect has been deemed to occur if the total LAeq noise level, including construction, exceeds the threshold level for the Category appropriate to the ambient noise level. Note 2: If the ambient noise level exceeds the Category C threshold values given in the table (i.e. the ambient noise level is higher than the above values), then a potential significant effect is indicated if the total LAeq, T noise level for the period increases by more than 3 dB due to site noise. Note 3: Applied to residential receptors only. Category A: threshold values to use when ambient noise levels (when rounded to the nearest 5dB) are less than these values. Category B: threshold values to use when ambient noise levels (when rounded to the nearest 5dB) are the same as category A values. Category C: threshold values to use when ambient noise levels (when rounded to the nearest 5dB) are higher than category A values. D) 19.00-23.00 weekdays, 13.00-23.00 Saturdays and 07.00-23.00 Sunday Table 2: Significance Criteria for the Assessment of Construction Noise Significance Level Above Threshold Value dB(A) Definition Neutral < 0 dB No effect, not significant, noise need not be considered as a determining fac- tor in the decision-making process. Slight adverse < 0 to <3 dB These effects may be raised but are unlikely to be of importance in the deci- sion-making process. Moderate adverse <3 to <5 dB These effects, if adverse, while important, are not likely to be key decision-mak- ing issues. Large adverse <5.0 to <10 dB The effects are likely to be important considerations but where mitigation may be effectively employed such that resultant adverse effects are likely to have a moderate or slight significance. Very large adverse >10 dB These effects represent key factors in the decision-making process. They are generally, but not exclusively, associated with impacts where mitigation is not practical or would be ineffective. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 11 3.2.2 Methodology and Target Criteria - Change in Road Traffic Noise The change in road traffic noise as a result of development-generated road traffic during the construction phase, includ- ing construction deliveries and plant movements, is assessed in accordance with methodology provided in CoRTN and ISO 9613. The magnitude of impact is defined by assessing the change in road traffic as a result of development generated traffic during the daytime periods at existing noise sensitive receptors. The site will not operate for construction during night-time periods, other than that required in respect of emergency works the classification of the magnitude of impacts used in this assessment is shown in Table 3. Table 3: Classification of Magnitude of Noise Impacts; Construction Road Traffic Noise Change in Noise Level, x LAeq, T dB Magnitude of Impact x > 5 Major adverse 3 < x <5 Moderate adverse 1< x <3 Minor adverse 0< x < 1 Negligible adverse x = 0 No change 3.3 Operational Noise Assessment Methodology Operational noise associated with the proposed development has been assessed using SoundPLAN Version 9.0 and hav- ing regard to the principles of BS 4142:2014+A1:2019. Long-term baseline monitoring at NML1 identified daytime background sound levels ranging from approximately 36 to 45 dB LA90,T and night-time background sound levels ranging from approximately 33 to 37 dB LA90,T. Representative background sound levels of 39 dB LA90,T during the daytime and 35 dB LA90,T during the night-time have been adopted for the purposes of the assessment. Representative existing ambient sound levels of 45 dB LAeq,T during the daytime and 38 dB LAeq,T during the night-time have similarly been adopted. The operational noise model incorporates the principal development-related noise sources, including recycler/vacuum tanker movements, residual-material unloading and transfer, secondary/final screening within the enclosed Debris Re- ception Building, process/transfer pumps, the biofilter/OCU extraction fan and vehicle/equipment washing. The available SoundPLAN receptor outputs for the operational assessment are expressed as Lden and Lnight. These met- rics are used to assess the relative contribution of the proposed development within the existing acoustic environment. Lden is not directly equivalent to a daytime BS 4142 specific sound level over the relevant reference period. The compar- ison with the measured LA90,T background sound level is therefore presented as a contextual assessment and shall not be interpreted as a formal BS 4142 LAr,Tr minus LA90,T rating assessment. BS 4142 principles are nevertheless applied in considering the character of the proposed sound, including the potential for tonality, impulsivity, intermittency and other readily distinctive acoustic characteristics. The potential change in total ambient sound level is additionally assessed by logarithmically combining the representative existing ambient sound level with the predicted development-related contribution. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 12 4.0 BASELINE MONITORING 4.1 Baseline Background Noise at Proposed Site A long-term noise survey was conducted on the proposed development site during day and night-time periods between 29th September 2025 to the 06th of October 2025. The purpose of the survey was to establish day and night-time background noise levels at the proposed site including weekends. Measurements were conducted using a Larson Davis Sound Expert 831, Larson Davis Sound Expert LXT and calibrated using a Cirrus calibrator before and after measurements, with a maximum drift of 0.3 dB noted. Calibration certificates are available on request. Measurements were conducted 1.5 m above ground using a fast time weighting. 4.1.1 Background Noise Monitoring Locations The noise monitoring locations are described in Table 4 and shown in Figures below.

REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 15 5.0 NOISE MODELLING 5.1 Noise Sensitive Receptors Four representative residential noise-sensitive receptor locations have been selected as being representative of the properties most exposed to construction and operational noise from the proposed development. These are shown in Figure 3. Assessment points are positioned at the façades orientated towards the application site to provide a conservative assessment. 5.2 Construction Noise Model Input Parameters 5.2.1 Predicted Construction Noise Levels and Modelled Scenarios Predicted noise levels for construction of the Proposed Development have been based upon construction methods used for other similar developments. As a worst-case approach, it is assumed that all plant and activities will be taking place at the closest approach to each NRSs, whereas in reality this will not always be the case and, in any event, activities are unlikely to occur for any significant duration. It is possible to predict typical noise levels using guidance set out in BS 5228- 1:2009+A1:2014. Table 9 outlines typical plant items and associated noise levels that are anticipated for various phases of the construction. Noise modelling scenarios have been set up to account for the cumulative impact of the construction activities for the construction phases.

REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 16 5.2.4 Associated HGV movements Construction deliveries have been assessed using a conservative worst-case allowance of up to 1 HGV movement per hour. Construction materials and plant will access the site via the existing road network and the site access to the southeast. This assumption is retained as a conservative construction traffic input and is not related to any infill activity. 5.2.5 Construction Noise Model Data Computer noise modelling of the various stages of construction activity at the site has been carried out using Sound plan software. Details on worst case construction activities, operating times, and associated items of noise generating plant for each phase of construction has been model. Calculations were carried out using noise data and guidance provided in BS5228-1:2009+A1:2014, to derive predicted noise levels at noise sensitive receptors. Full details of the items of modelled construction plant for each of the considered scenarios is shown in table 9 above. 5.2.6 Construction Noise Model Assumptions A number of assumptions have been established during the Sound plan modelling exercise, as detailed below: • Predicted levels are calculated in the free field environment. • Ground absorption has been set to 1 for areas of soft ground. Areas of hard ground have been set to 0.1 for reflective surfaces. • The noise model assumes locations of plant based on descriptions of construction activities. • Worst case scenario combinations of construction activities are likely to occur in any one day. during the considered assessment periods have been assumed. • The following sources have been modelled as line sources within Soundplan. o Heavy goods vehicles (HGVs) and dump trucks. o Moving construction plant. • All remaining sources (not outlined above) have been modelled within Soundplan as point sources. 5.2.7 ABC Category Thresholds The appropriate ABC category thresholds above which there is considered to be a noise impact from construction noise have been calculated following guidance provided in BS5228-1:2009+A1:2014 (refer to Section 3.2.1). 5.2.8 Change in Road Traffic during Construction Phase The noise levels associated with mobile plant items such as concrete mixer trucks, loaders etc. operational on site have been included as part of the construction noise assessment and calculated noise levels in Table 9. Consideration should also be given to the addition of construction traffic along the site access routes. Access to the development site for construction traffic will be via the road to the southeast proposed development. It is possible to calculate the noise levels associated with the passing vehicle using the following formula. LAeq,T = LAX+ 10log 10(N) - 10log10(T) + 10log10(r1/ r2) dB Where: LAeq,T = is the equivalent continuous sound level over the time period Tin seconds. LAX = is the "A-weighted" Sound Exposure Level of the event considered(dB). N = is the number of events over the course of time period T. r1= is the distance at which LAX is expressed. r2= is the distance to the assessment location REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 17 5.3 Operational Noise Model Input Parameters 5.3.1 Operational Noise Data Operational noise has been assessed using SoundPLAN v9.0. The revised source schedule below reflects the clarified JC Environmental operation. It represents a conservative peak-hour condition notwithstanding that the site is limited to JC Environmental's own material, has a maximum annual intake of 2,000 tonnes per annum, and the majority of liquid/solid separation occurs in the recycler vehicle before the residual material returns to Mullanarry. Manufacturer-specific data are used where available; otherwise, recognised source-library or comparable waste-facility data are adopted. Routine waste reception and processing hours are Monday to Friday 08:00-19:00 and Saturday 08:00-16:00. No routine waste reception or processing will occur on Sundays or Public Holidays. The OCU fan is conservatively assessed as capa- ble of operating outside these hours where required for odour control.

REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 18 5.3.2 Operational Noise Model Assumptions The following assumptions are applied to the operational noise model: • predicted receptor levels are calculated in the free-field environment; • ground absorption is set to 1.0 for soft ground and 0.1 for hard/reflective surfaces; • JC Environmental recycler/vacuum tanker movements are represented as mobile line/area sources along the internal route; • the site will serve JC Environmental only and no third-party waste deliveries are included in the operational traf- fic scenario; • the maximum annual waste intake is limited to 2,000 tonnes per annum; • most liquid/solid separation occurs within the recycler vehicle before return to site, so on-site screening is a sec- ondary/final step and only a limited residual liquid fraction is handled; • routine waste reception and processing are limited to 08:00-19:00 Monday-Friday and 08:00-16:00 Saturday; • no routine waste reception or processing occurs on Sundays or Public Holidays; • all routine unloading and secondary/final screening occurs within the enclosed Debris Reception Building (ap- proximately 192 m2 floor area); • fixed mechanical plant is represented as point or area sources as appropriate; • Secondary/final screening and residual-material handling are located within the enclosed Debris Reception Building. The operational acoustic model incorporates attenuation through the building envelope for these internal sources. • The modelled building envelope assumes a minimum acoustic reduction 30dB for the relevant wall/roof/door construction. The final building specification shall provide acoustic performance equal to or better than this modelled value. • Roller-shutter doors shall remain closed during unloading, transfer and screening activities except for the mini- mum period required for vehicle entry and exit. The acoustic model represents normal processing with the building enclosed. • The final construction specification shall provide an acoustic performance equal to or better than that as- sumed within the operational noise model. • the duty/standby OCU arrangement is represented by one duty fan operating; the standby fan is not assumed to operate simultaneously; • the OCU fan is conservatively assessed as capable of continuous operation, including outside routine waste- processing hours where required for odour control. Accordingly, the night-time operational assessment represents a conservative scenario in which the OCU fan may operate when routine waste reception, unloading, screening and vehicle/equipment washing activities have ceased. • the duty-cycle assumptions in Table 10 represent conservative peak-hour operation rather than average daily utilisation; • relevant sources are assumed capable of operating concurrently where this gives the conservative assessment; and • appropriate acoustic feature corrections for tonality, impulsivity and intermittency are considered in accordance with BS 4142:2014+A1:2019. • The final OCU arrangement incorporates the revised 7.45 m vertical treated-air discharge. The acoustic assessment shall include any sound radiated from the OCU fan, ductwork and terminal exhaust arrangement. Where the exhaust outlet constitutes a separate radiating source, its source height and acoustic emission shall be represented in the final acoustic model.

The site will not operate during night-time other than required emergency works. The outcome of the BS5228 assessment is that Neutral impacts are predicted at the surrounding residential receptors as a result of all construction phases during the day periods with proposed mitigation measures. 6.2 Construction Road Traffic Noise Levels A calculation distance of 5m from the road has been used to assess noise levels at the closest buildings along the construction routes. The mean value of Sound Exposure Level for truck moving at low to moderate speeds (i.e. 15 to 45km/hr) is of the order of 82dB Lax at a distance of 5 metres from the vehicle. This figure is based on a series of measurements conducted under controlled conditions. Construction vehicles are predicted in the table below for peak hours associated with each key phase. Table 15 below summarises the calculated noise level associated with passing haul vehicles during each phase, assuming the peak flows per day. Table 15: Calculated Construction Traffic Noise Levels at Edge of Road Construction Scenario /Phase No. of Trucks/peak hour Calculated Noise at edge of road (5m), dB LAeq, 1hr 1 1 63 2 1 63 The calculated noise levels associated with the various phases are in the 63dB LAeq,1hr. The calculated noise levels are below the construction noise criterion of 65dB. In addition, it should be noted that, in order to assess a worst­ case sce- nario, a large proportion of the daily vehicle numbers have been assumed to arrive/depart over a daily period.

The principal potentially continuous source is the OCU extraction fan. Pumps and mechanical equipment may also exhibit tonal characteristics if inadequately selected or maintained, while unloading, debris handling and vehicle movements may generate intermittent or impulsive sound. The operational noise model outputs are expressed as Lden and Lnight and are therefore not presented as formal BS 4142 specific or rating levels. No numerical BS 4142 character correction has consequently been added directly to the Lden/Lnight model outputs. Notwithstanding this, the final OCU fan, pumps and other fixed plant shall be selected to avoid prominent tonal, im- pulsive or other readily distinctive characteristics at the nearest residential receptors. Where manufacturer data or commissioning measurements identify such characteristics, appropriate attenuation shall be installed. The existing receiving environment is influenced principally by road traffic together with existing commercial and in- dustrial activity. The significance of the proposed development has therefore been considered both in terms of pre- dicted development-related sound and the potential change in the existing measured acoustic environment. . 7.2 Revised Operational Noise Model Results The operational noise model has been updated using the revised operational source schedule presented in Table 10. The model incorporates the principal operational noise sources associated with the proposed development, including recycler/vacuum tanker movements, residual material unloading and transfer, secondary/final screening within the enclosed Debris Reception Building, the process/transfer pump, the biofilter/odour control unit fan and vehicle/equip- ment washing. The model represents a conservative operational scenario based on the source levels and duty cycles presented in Table 10. Predicted noise levels have been calculated at the four representative residential noise-sensitive receptors identified in Section 5.1. The predicted operational noise levels are summarised in Table 16 below. Table 16: Predicted Operational Noise Levels at Noise-Sensitive Receptors Noise-sensitive receptor Predicted Lden dB Predicted Lnight dB NSL 1 36.6 29.7 NSL 2 32.8 28.5 NSL 3 41.7 38.2 NSL 4 31.0 24.8 The highest predicted operational noise level occurs at NSL3, where a maximum level of approximately 42 dB Lden and 38 dB Lnight is predicted.. Predicted levels at the remaining receptors are lower, with Lden values ranging from approximately 31.0 to 36.6 dB and Lnight values ranging from approximately 24.8 to 29.7 dB. These results indicate that operational noise from the proposed development will remain relatively low at the surround- ing residential receptors. The results are also considered in the context of the measured existing acoustic environment presented in Section 4. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 23 7.3 Representative Background Sound Level Long-term monitoring at NML1 identified the existing acoustic environment over a seven-day monitoring period. The daily daytime LA90,T values were 39, 40, 39, 41, 45, 37 and 36 dB, giving a median representative daytime background sound level of 39 dB LA90,T. The corresponding daytime LAeq,T values were 43, 45, 44, 46, 50, 47 and 39 dB, giving a median representative ambient level of 45 dB LAeq,T. The daily night-time LA90,T values were 37, 35, 33, 36, 35, 34 and 37 dB, giving a median representative night -time background sound level of 35 dB LA90,T. The corresponding night-time LAeq,T values were 40, 38, 36, 39, 37, 36 and 39 dB, giving a median representative ambient level of 38 dB LAeq,T. These levels have been adopted as representative of the existing acoustic environment for the purposes of assessing the potential change associated with the proposed development. 7.4 Predicted Change in Existing Acoustic Environment Table 17: Indicative Daytime Change in Existing Ambient Noise Level due to Proposed Operations Receptor Existing representa- tive ambient, dB LAeq,T Modelled opera- tional level, dB Calculated total, dB Indicative increase, dB NSL1 45 36.6 45.6 +0.6 NSL2 45 32.8 45.3 +0.3 NSL3 45 41.7 46.7 +1.7 NSL4 45 31.0 45.2 +0.2 On this basis, the modelled development contribution would result in an indicative daytime change of approximately +0.2 to +1.7 dB, with the greatest change predicted at NSL3 to the east of the site. Changes of this magnitude are small relative to the existing measured acoustic environment. The highest indicative daytime increase is approximately +1.7 dB at NSL3, with increases at the remaining receptors not exceeding approximately +0.6 dB. As the daytime model output is expressed as Lden rather than daytime LAeq,T, these calculations are presented as a contextual indication of the likely magnitude of change and not as a formal like-for-like daytime LAeq,T comparison.

The night-time modelling represents the conservative operational condition associated principally with the OCU fan, which is assumed capable of operating outside routine waste -processing hours.

The predicted development-related contribution at this location is approximately 41.7 dB Lden and 38.2 dB Lnight. During the daytime, logarithmic combination of the predicted development contribution with the representative existing ambient sound level indicates an increase of approximately +1.7 dB at NSL3. The conservative night-time scenario, associated principally with operation of the OCU extraction fan, indicates an increase of approximately +3.1 dB in total sound level at NSL3. These changes are presented as contextual indicators rather than a formal BS 4142 rating-level assessment because the operational model outputs are expressed as Lden and Lnight. The night-time result reinforces the requirement for the final OCU fan and associated ductwork to meet the acoustic design limit adopted within the model and to avoid prominent tonal characteristics. Compliance shall be verified following commissioning.

REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 8.0 MITIGATION MEASURES 8.1 Construction Phase With regard to construction activities, best practice control measures for noise and vibration from construction sites are found within BS 5228 (2009 +A1 2014) Code of Practice for Noise and Vibration Control on Construction and Open Sites Parts 1 and 2. Whilst construction noise and vibration impacts are expected to vary during the construction/demolition phase depending on the distance between the activities and noise sensitive buildings, the contractor will ensure that all best practice noise and vibration control methods will be used, as necessary in order to ensure impacts at off -site noise sensitive locations are minimised. The best practice measures set out in BS 5228 (2009) Parts 1 and 2 includes guidance on several aspects of construction site mitigation measures, including, but not limited to: • Selection of quiet plants. • Noise control at source. • Screening. • Liaison with the public • Monitoring A detailed comment is offered on these items in the following paragraphs. Noise control measures that will be considered include the selection of quiet plant, enclosures, and screens around noise sources, limiting the hours of work and noise and vibration monitoring, where required. Selection of Quiet Plant This practice is recommended in relation to static plant such as compressors and generators. It is recommended that these units be supplied with manufacturers' proprietary acoustic enclosures. The potential for any item of plant to generate noise will be assessed prior to the item being brought onto the site. The least noisy item should be selected wherever possible. Should a particular item of plant already on the site be found to generate high noise levels, the first action should be to identify whether or not said item can be replaced with a quieter alternative. Noise Control at Source If replacing a noisy item of plant is not a viable or practical option, consideration will be given to noise control "at source". This refers to the modification of an item of plant or the application of improved sound reduction methods in consultation with the supplier. For example, resonance effects in panel work or cover plates can be reduced through stiffening or application of damping compounds; rattling and grinding noises can often be controlled by fixing resilient materials in between the surfaces in contact. Referring to the potential noise generating sources for the works under consideration, the following best practice mitigation measures should be considered: • Site compounds will be located as far as reasonably practicable from the nearest noise-sensitive receptors, hav- ing regard to the physical constraints of the application site. For mobile plant items such as dump trucks, exca- vators and loaders, the installation of an acoustic exhaust and/or maintaining enclosure panels closed during operation can reduce noise levels by up to 10dB. Mobile plant should be switched off when not in u se and not left idling. • For steady continuous noise, such as that generated by diesel engines, it may be possible to reduce the noise emitted by fitting a more effective exhaust silencer system or utilising an acoustic canopy to replace the normal engine cover. For concrete mixers, control measures should be employed during cleaning to ensure no impulsive hammering is undertaken at the mixer drum. • For all materials handling ensure that materials are not dropped from excessive heights, lining drops chutes and dump trucks with resilient materials. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 27 • For compressors, generators, and pumps, these can be surrounded by acoustic lagging or enclosed with acous- tic enclosures providing air ventilation. • Demountable enclosures can also be used for screen operations using hand tools and will be moved around site, as necessary. • All items of plant should be subject to regular maintenance. Such maintenance can prevent unnecessary in- creases in plant noise and can serve to prolong the effectiveness of noise control measures. Screening Screening is an effective method of reducing the noise level at a receiver location and can be used successfully as an additional measure to all other forms of noise control. Where required to control construction noise, solid close-boarded construction hoarding or an equivalent temporary acoustic screen will be installed along the relevant site boundary. The hoarding shall be continuous, without significant gaps, and positioned to interrupt the direct line of sight between significant construction noise sources and nearby residential receptors. Liaison with the Public A designated environmental liaison officer will be appointed to site during construction works. Any noise complaints should be logged and followed up in a prompt fashion by the liaison officer. In addition, where a particularly noisy construction activity is planned or other works with the potential to generate high levels of noise, or where noisy works are expected to operate outside of normal working hours etc., the liaison officer will inform the nearest noise sensitive locations of the time and expected duration of the noisy works. Monitoring Where required, construction noise monitoring will be undertaken at periodic sample periods at the nearest noise sensitive locations to the development works to check compliance with the construction noise criterion. Noise monitoring should be conducted in accordance with the International Standard ISO 1996: 2017: Acoustics - Description, measurement, and assessment of environmental noise. 8.2 Operational Phase • All routine residual-waste unloading, secondary/final screening and transfer operations shall be undertaken within the enclosed Debris Reception Building. • The site shall be used solely for JC Environmental operations; no third-party waste shall be accepted. • Routine waste reception and processing shall be limited to 08:00-19:00 Monday-Friday and 08:00-16:00 Saturday, with no routine waste reception or processing on Sundays or Public Holidays. • The majority of liquid/solid separation shall occur in the recycler vehicle before return to site; on-site screening is limited to a secondary/final step. • External doors associated with the Debris Reception Building shall remain closed during unloading and screening except for the minimum period necessary for vehicle entry and exit. • Fixed mechanical plant shall be selected so that installed sound emissions do not exceed the source levels adopted in Table 10 unless additional acoustic attenuation is provided. • The nominal 4,000 m3/hr biofilter/OCU fan shall be appropriately specified and, where required, fitted with acoustic attenuation so that the installed sound emission does not exceed the source level adopted in Table 10 and compliance is achieved at the nearest residential receptors. • Pumps and other continuously operating equipment shall be acoustically enclosed or attenuated where required. • Plant shall be maintained in accordance with manufacturer recommendations to prevent unnecessary increases in noise. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 28 • Recycler/vacuum tanker engines shall not be left idling unnecessarily and vehicle manoeuvring shall be organised to minimise reversing where reasonably practicable. • Residual-material unloading, transfer and handling shall be undertaken to minimise impact, dropping and clattering. • Vehicle/equipment washing shall be restricted to routine operational hours. • Any noise complaint shall be recorded, investigated promptly and corrective action implemented where necessary. • Where warranted following commencement of operations, attended compliance monitoring shall be undertaken at the nearest noise-sensitive receptors. • Prior to commencement of full operation, the final OCU fan acoustic specification shall be reviewed and veri- fied against the source level adopted within the operational acoustic model. Where required, silencers, acous- tic enclosures, duct attenuators or other appropriate noise-control measures shall be installed. • Following commissioning of the OCU and associated mechanical plant, attended environmental noise moni- toring shall be undertaken at the nearest representative residential receptor(s), including NSL3. • Commissioning monitoring shall include LAeq,T, LA90,T and appropriate frequency-domain observations suffi- cient to identify any tonal or other distinctive acoustic characteristics associated with the OCU or other fixed plant. • Where commissioning measurements identify a material exceedance of the acoustic design assumptions or prominent tonal characteristics, additional attenuation shall be installed before unrestricted routine operation. • Any subsequent substantiated noise complaint shall be investigated promptly and shall trigger additional at- tended monitoring where appropriate. 9.0 CONCLUSIONS 9.1 Construction Noise Assessment in accordance with BS 5228-1:2009+A1:2014 A noise assessment was carried out to establish the potential impact of construction noise on the nearest noise -sensitive properties, based on BS 5228-1:2009+A1:2014. Conservative construction scenarios have been modelled for site preparation and general construction activities associated with the construction and fit-out of the enclosed Debris Reception Building, biofilter/OCU installation, covered tank area, concrete apron and ancillary works. The outcome of the assessment is that Neutral impacts are predicted during the daytime periods during all construction phases. There will be no significant adverse impacts in noise terms providing mitigation measures are implemented. 9.2 Operational Noise Assessment Having Regard to BS 4142:2014+A1:2019 The operational noise assessment has been updated to reflect the revised development proposal and operational source schedule. All routine residual-material unloading, secondary/final screening and associated waste-handling activities will take place within the dedicated enclosed 192 m² Debris Reception Building. The site will be used solely in connection with material arising from JC Environmental's own operations, with no third-party waste accepted and a maximum annual intake of 2,000 tonnes per annum. Routine waste reception and processing will be limited to 08:00–19:00 Monday to Friday and 08:00–16:00 Saturday, with no routine waste reception or processing on Sundays or Public Holidays. The operational assessment includes recycler/vacuum tanker movements, controlled residual-material unloading and transfer, secondary/final screening, process/transfer pumps, the OCU extraction fan and vehicle/equipment washing. The model predicts development-related levels of approximately 31.0–41.7 dB Lden and 24.8–38.2 dB Lnight at the four representative residential receptors, with NSL3 representing the controlling receptor. REC E I V E D : 1 6 / 0 9 / 2 0 2 6 Noise Impact Assessment 29 Long-term monitoring identified representative background sound levels of approximately 39 dB LA90,T during the daytime and 35 dB LA90,T during the night-time, together with representative ambient levels of approximately 45 dB LAeq,T during the daytime and 38 dB LAeq,T during the night-time. Logarithmic combination of the predicted development contribution with the representative existing ambient environment indicates an approximate change of +0.2 to +1.7 dB during the daytime and +0.2 to +3.1 dB during the conservative night-time scenario. The operational SoundPLAN outputs are expressed as Lden and Lnight and the comparison with measured background levels is therefore presented as a contextual assessment having regard to BS 4142 principles, rather than as a formal LAr,Tr minus LA90,T assessment. The conservative night-time assessment is associated principally with potential operation of the OCU extraction fan outside routine processing hours. No routine waste reception, unloading, screening, transfer or vehicle/equipment washing will occur during the night-time period. The final OCU fan and associated ductwork shall be selected and acoustically attenuated as necessary to achieve the acoustic source specification adopted within the model and to avoid prominent tonal or other distinctive characteristics at residential receptors. Following installation and commissioning, attended noise monitoring shall be undertaken at the nearest representative receptor(s), including NSL3, to verify the model assumptions and the effectiveness of the installed noise-control measures. Subject to the enclosure of principal processing activities, implementation of the mitigation measures specified in Section 8.2 and verification of fixed-plant acoustic performance following commissioning, the proposed development is not predicted to result in a significant adverse noise impact at the nearest residential noise-sensitive receptors.
