This report presents the results of the noise assessment for the proposed development. The noise assessment considers the construction and operational noise impacts at existing sensitive receptors surrounding the site. Planning permission was applied for previously and further information was requested. The period of the response lapsed and the application was deemed withdrawn. The below further information was requested as part of the FI previously. As part of the previous Further information request “Notwithstanding the information submitted, concerns remain regarding potential noise and general disturbance impacts on the surrounding area, particularly the adjacent residential properties along the roadside. By the numbers, there may be 1500 HCV trips to the site over the proposed period. Submit an assessment of potential impacts in respect of noise and general disturbance, which assesses the likely impacts during the operational phase of the proposed development on the nearest sensitive locations, i.e. the adjacent residential properties along the roadside. Whatever risks to the surrounding area are identified, please clearly demonstrate how same would be acceptably mitigated. The assessment should be specific to the characteristics of the subject site and the setting, and shall be carried out by a suitably qualified person. 1.1 Site Description This report has provided supporting information to accompany a planning application to Monaghan County Council. It primarily addresses the potential noise and vibrations related impacts from the infilling of the site at Binmore, Castleblayn ey, Co. Monaghan using soil and stones generated by construction and development projects across County Monaghan to restore it to a beneficial agricultural land-use. 1.2 Existing Use The site comprises an area of land currently Used for agricultural purposes. 1.3 Proposed Development The proposed development will consist of: • the re-contouring of existing undulating agricultural farmland to include the importation of soil, subsoil and inert material in order to raise the levels of part of the land together with all ancillary site development works. The lands will be recovered with topsoil and reseeded with ryegrass upon completion of the re-contouring works The Application Site (‘the Site’) is located at Binmore, Castleblayney, Co. Monaghan, A00AA00. The Site measures ca 1.37 (ha) in total. It is a green field site. The infilling operations will be carried out through the importation of inert material and soil and stones suitable for resto ration purposes. Importation of natural inert soil and stones waste will require a WFP or Article 27 approval from Monaghan County Council or the EPA respectively, in addition to planning permission. An operational vibration assessment has not been undertaken as previous experience and site survey information indicates that little or no vibration arises from activities of this nature and, as such, no vibration assessment is required. RECEIVED: 15/10/2025 Noise Impact Assessment 6 1.4 Potential Impacts Noise from the proposed development has the potential to impact surrounding existing residential receptors during the construction (infilling) and operational phases. This Noise Impact Assessment has addressed noise in relation to the construction (infilling) and operational phases. 1.4.1 Construction Phase Noise from HGV movements associated with the construction phase has the potential to impact existing noise sensitive receptors located along the routes to and from the site. 1.4.2 Operational Phase The following activities have been identified as having the potential to increase noise levels in the surrounding area during the operational phase. Figure 1: Site Location and site layout RECEIVED: 15/10/2025 Noise Impact Assessment 7 2.0 NOISE POLICY AND GUIDANCE This section outlines policy and guidance relevant to this Noise Impact Assessment. 2.1 Assessment of Noise A five-stage process to the assessment of noise, as detailed below. 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. RECEIVED: 15/10/2025 Noise Impact Assessment 8 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. 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. RECEIVED: 15/10/2025 Noise Impact Assessment 9 “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, d esign 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). RECEIVED: 15/10/2025 Noise Impact Assessment 10 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. • Short term measurements of existing baseline noise environment at a sample of areas representative of the most exposed noise sensitive receptors (NSRs) surrounding the proposed development; the monitoring locations. • Long-term Measurements of existing baseline noise environment at selected locations on the proposed site. The monitoring locations. • Review of proposed construction activities, locations, and noise data. • Calculation and assessment of construction noise at the most exposed sensitive receptors, following guidance pro- vided in BS5228-1:2009+A1:2-014; Code of Practice for Noise and Vibration on Construction and Open Sites. Com- puter noise modelling using Sound plan software has been used in the calculation of construction noise at sensitive receptors. • Review of proposed operational activities, locations, and noise data. • 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 infilling 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 exceed- ance 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 con- struction 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 ex- ceeds 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 signifi- cance, guidance provided in the RECEIVED: 15/10/2025 Noise Impact Assessment 11 • The significance criteria adopted within this noise assessment are shown in Table 2. Table 2: Significance Criteria for the Assessment of Construction Noise Significance Level Above Threshold Value dB(A) Definition Neutral < 0 No effect, not significant, noise need not be considered as a determining fac- tor in the decision-making process. Slight adverse < 0 to <3 These effects may be raised but are unlikely to be of importance in the deci- sion-making process. Moderate adverse <3 to <5 These effects, if adverse, while important, are not likely to be key decision-mak- ing issues. Large adverse <5.0 to <10 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 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. 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 (specifically HGVs associated with infill activities) 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 RECEIVED: 15/10/2025 Noise Impact Assessment 12 3.3 Operational Noise Assessment Target Criteria Proposed activities from the operations within the site are assessed following guidance provided in BS4142:2014. The noise criteria to be applied to operational industrial noise is summarised in Table 4. The table is used as follows. • Calculate the difference between the rated operational noise level (Lar, T) and the background noise (LA90, T) at each noise sensitive receptor, following principles defined in BS4142:2014. • This difference in levels is used to define the Sensitivity of Receptor, as shown in Table 4. Calculate the total noise at each noise sensitive receptor, including operational activity (LAeq, T). • The difference between the total noise including operational activity, and that before development at each sensi- tive receptor is used to define the Magnitude of Impact, as shown in Table 4. • The Significance of Impact is then defined, as shown in Table 4.

RECEIVED: 15/10/2025 Noise Impact Assessment 20 5.0 NOISE MODELLING 5.1 Noise Sensitive Receptors Six residential noise sensitive receptors have been chosen as being representative of those most exposed to noise from construction and operational activities at the proposed development. These are described in Table 20 above. Noise modelling and the site visit has determined that the most exposed properties are the 6 NSLs described in Table 13 above. 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 21 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 infilling / landscaping phases.

The HGV route will to on the existing road to the southeast of the site. HGV movements have been modelled using a worst case of 1 HGVs per hour. 5.2.5 Construction Noise Model Data Computer noise modelling of the various stages of infilling 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 17 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 Sound plan. o Heavy goods vehicles (HGVs) and dump trucks. o Moving construction plant. • All remaining sources (not outlined above) have been modelled within Sound plan as point sources. 5.2.7 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 17. Consideration should also be given to the addition of construction traffic along the site access routes. Access to the development site for construction t raffic 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. RECEIVED: 15/10/2025 Noise Impact Assessment 22 r1= is the distance at which LAX is expressed. r2= is the distance to the assessment location 5.3 Operational Noise Model Input Parameters 5.3.1 Operational Noise Data Computer noise modelling of operational activity at the proposed development has been carried out using Sound plan v9.0 software. Calculations were carried out using published data in BS5228:2009+A1:2014, to derive predicted noise levels at noise sensitive receptors. 5.3.2 Operational 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 reflec- tive surfaces. • Vehicle movements have been modelled as area sources within Sound plan.

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 23 below summarises the calculated noise level associated with passing haul vehicles during each phase, assuming the peak flows per day.

To calculate the rated sound level, the assessment considers the character of the sound being assessed at the receptor location. If present, corrections for impulsivity, intermittency and/or tonality are added to the specific sound level to calculate the rated sound level. A sound source may exhibit acoustic characters at source; however, the prominence of these features may be masked at the location of the noise sensitive receptors by the residual (background) sound at these locations. The amount by which the residual sound masks these features varies as the residual sound changes in level and possible character. Similarly, the sources acoustic character may also vary with time. To comply with WHO Requirements an acoustic fence is required between the infill site and the nearest residential houses.

Screening is an effective method of reducing the noise level at a receiver location and can be used successfully as an addi- tional measure to all other forms of noise control. Construction site hoarding will be constructed around the site boundaries as standard especially near the existing houses. The hoarding will be constructed of a material to reduce noise by 25dB along the boundaries of the site to protect the nearest receptors. This will ensure guidance limit for construction noise at nearest noise sensitive location is followed and potential impacts relating to noise nuisance and disturbance and vibration impacts are effectively minimised and controlled. A risk-based approach is to be used considering the locality, nature of the work and the expected duration of the work. The risk category of the site is high risk therefore the following mitigation measures are required. This document is produced by Monaghan County Council. 8.1.1 General Considerations • All site staff shall be briefed on noise mitigation measures and the application of the best practicable means to be employed to control dust. • Good Quality site hoarding should be erected to maximise the reduction in noise levels. • The contact details of the contractor and site manager shall be displayed to the public, together with the permit- ted operating hours, including any special permissions given for out-of-hours work. • The site entrance shall be located to minimise disturbance to noise sensitive receptors. • Internal haul routes shall be maintained, and steep gradients shall be avoided. • Material and plant loading and unloading shall only take place during normal working hours unless the requirement for extended hours is for traffic management (i.e. road closure) or health and reasons. 8.1.2 Plant • Ensure that each item of plant and equipment complies with the noise limits quoted in the relevant European Commission Directive 2000/14/EC. • Fit all plant and equipment with appropriate mufflers or silencers of the type recommended by the manufacturer. • Use all plant and equipment only for the tasks for which it has been designed. • Shut down all plant and equipment in intermittent use in the intervening periods between work or throttle down to a minimum. • Power all plant by mains electricity where possible rather than generators. • Maximise screening from existing features or structures and employ the use of partial or full enclosures for plant. • Locate movable plant away from noise sensitive receptors. • Due to the proximity to local residents and the likely use of generators to provide power to the cranes, generators will be placed at the most less intrusive location. Generators will have acoustic barriers/enclosures built around them in order to reduce sound levels at the nearest noise sensitive receptors. • The hours of operation during the demolition and construction phase shall be restricted to 7.00am to 6pm, Monday to Friday, and 8.00am to 2.00pm on Saturdays. Permission to work outside of these hours must be subject to the approval of Monaghan County Council. RECEIVED: 15/10/2025 Noise Impact Assessment 28 8.1.3 Vehicle activity • Ensure all vehicle movements (on site) occur within normal working hours. (other than where extension of work requiring such movements has been granted in cases of required road closures or for health and safety reasons). • Plan deliveries and vehicle movements so that vehicles are not waiting or queuing on the public roads. If unavoidable engines should be turned off. • Minimise the opening and closing of the site, access through good coordination of deliveries and vehicle movements. • Plan the site layout to ensure that reversing is kept to a minimum. • Where reversing is required use broadband reverse sirens or where it is safe to do so disengage all sirens and use banksmen. • Rubber/neoprene or similar non-metal lining material mating to line the inside of material transportation vehicles to avoid first dropping high noise levels. • Wheel washing of vehicles prior to exiting the site shall take place to ensure that adjoining roads are kept clean of dirt and debris. Regular washing of adjoining streets should also be carried out by the developer, as required by mechanical road sweepers. 8.1.5 Monitoring • Carry out regular on-site observation monitoring and checks/audits to ensure that BPM is being used at all times. Such checks shall include. o Hours of work o Presence of mitigation measures o Number and type of plant o Construction methods • Site reviews must be recorded and made available for inspection. • Monitor noise and vibration continuously during demolition, piling, excavation and sub and superstructure works at agreed locations and report to MCC at agreed intervals and in an agreed format. To comply with this the following must take place. • The monitoring locations for existing sites as agreed with officers of Monaghan County Council must remain in situ. If additional monitoring is required, this will be provided, and the new locations will be agreed with Monaghan County Council. • Provide the construction noise level as defined in British Standard 5228 and the peak particle velocity readings for the hours of operation of the site. This will include the construction noise level for any overtime period worked outside of normal working hours. Provide a report detailing and discussing the noise and vibration lev- els over the reporting period. If a breach is recorded the follow-up action that took place to prevent any fur- ther breaches must be included in the report. • Appraise and review working methods, processes, and procedures on a regular basis to ensure continuous development of BPM. • The ‘ABC’ Method detailed in Paragraph E.3.2 of BS 5228-1:2009 shall be used to determine acceptable noise levels for day, evening and nighttime work. • Vibration levels must be kept below 1.0 mm/sec (PPV) where possible. Where levels are expected to exceed this value residents must be warned, and an explanation given. • Appropriate dust suppression must be employed to prevent fugitive emissions affecting those occupying neighbouring properties or pathways. RECEIVED: 15/10/2025 Noise Impact Assessment 29 • Street and footpath cleaning must be undertaken during the demolition and ground works phase to minimise dust emissions. 8.1.6 Communication and Liaison • Contact details for the site manager and liaison officer should be displayed prominently on the site hoarding. • All staff should be briefed on the complaint’s procedure and the mitigation requirement and their responsibilities to register and escalate the complaints received. • Send regular updates at appropriate intervals to all identified affected neighbours post relevant information on the site hoarding. Also make the information available via email/website including weekly noise monitoring reports. • Arrange regular community liaison meetings at appropriate intervals including prior to commencement of the project. • Meet regularly with neighbouring construction sites to ensure activities are coordinated to minimise any potential cu- mulative issues. 8.1.7 Extensions of Working Hours in exceptional circumstances • The hours of operation during the demolition and construction phase shall be restricted to 7.00am to 6pm, Monday to Friday, and 8.00am to 2.00pm on Saturdays. Permission to work outside of these hours must be subject to the approval of Monaghan County Council. • Ensure at least 4 days’ notice is given to Monaghan County Council Planning Department when applying for extensions to normal working hours. Do not undertake out-of-hours work unless permission to do so has been granted. • The applicant must demonstrate in writing that the work required cannot be carried out during normal working hours. The documentation sent must be accompanied by a detailed engineering or/and traffic management or/and safety case as to why the work is required outside normal hours. • Power floating after 6pm is the only activity that will be permitted during the extensions where they relate to required large concrete pours. All reasonable and appropriate measures to minimise noise associated with these works must be put in place and no works other than those approved may be carried out during extended working hours. • The Developer/his agent must give the times and dates of the proposed work, and the mitigation measures that are to be used to minimise noise/disturbance. • Advise neighbours about the requirement for and duration of any permitted work outside of normal working hours and associated environmental mitigation measures being put in place during the course of the extended works, following receipt of approval from DCC. • All complaints will be referred directly to the site liaison person, and a reply must be issued to the complaint within 3 hours of receipt of the complaint. • A log of all complaints and a summary of how they were dealt with should be kept and be made available to DCC, as required. • Any breaches of permitted working hours or permitted extended working hours or developers or subcontractors not carrying out their requirements under this protocol may lead to enforcement action and may also result in the withdrawal of any extension of hours of work for a period that will be at the discretion of Monaghan County Council. 8.2 Operational Phase As the proposed development will be used for agricultural activities once infilling is complete there is no requirement for additional mitigation measures only standard agricultural best practices. . RECEIVED: 15/10/2025 Noise Impact Assessment 30 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 (infilling) noise on the nearest noise sensitive properties, based on BS 5228-1:2009+A1:2014.” Worst case combined construction (infilling) stages have been modelled using Sound plan v9.0 software. The outcome of the assessment is that mitigation measures including an acoustic fence to be installed between the site and the nearest houses is required to ensure compliance with WHO Requirements during the daytime periods. There will be no infilling activities during night-time. There will be no significant adverse impacts in noise terms providing mitigation measures are implemented. As the proposed development will be used for agricultural activities once infilling is complete there is no requirement for additional mitigation measures only standard agricultural best practices.
