SECTION 7 - NOISE

7.1 INTRODUCTION

7.1.1 Planning consent for extraction of sand at Grandcourt Quarry, East Winch was granted to Sibelco by Norfolk County Council in 2007. Sibelco is now seeking to extend the area of mineral extraction into land to the east of the consented reserves. Transport of the extracted sand from this site to the existing stockpiling and plant feed site at Leziate will continue to be by articulated dumptrucks using the internal dedicated haul route.

7.1.2 An assessment of the potential impact at the closest noise sensitive properties, due to noise arising from proposed quarrying activity has been undertaken and the findings are set out in the following report.

7.2 BASIS OF ASSESSMENT

7.2.1 The proposed quarry extension will entail mobile plant operating closer a number of noise sensitive residential properties. In order to evaluate the impact of the proposals scheme on these noise sensitive properties, a quantitative assessment has been conducted. The basis of this assessment is as follows:-

. Identification of significant noise sources and noise generating activities. . Assessment of sound pressure levels from main sources and activities to determine sound power levels. . Measurement of existing background and ambient noise levels at the noise sensitive properties. . Calculation of received noise levels at the properties arising from the proposed site activities. . Comparison of predicted noise levels with existing noise levels and with relevant noise criteria. . Proposals for mitigation of impacts (if required)

7.3 SITE DESCRIPTION

7.3.1 The Grandcourt Quarry site is situated approximately one mile south east of the mineral processing site at Leziate. The site is located on the northern side of the A47 trunk road with East Winch village to the east. The current quarry is located to the west and north- PART TWO NOISE

west. The existing haul route to transport sand between the quarry and processing plant will remain in use with a short additional section at the eastern end to link into the new deposit.

7.3.2 The extension area land varies from an elevation of around 26m above ordnance datum (AOD) in the south west, falling towards the north and east to an elevation of 14m AOD. There are no existing landforms or topographical features within the site that would significantly influence noise propagation towards neighbouring noise sensitive properties. The land is currently used as arable farm land and in acoustic terms, is soft.

7.4 NOISE SENSITIVE PROPERTIES

7.4.1 There are only two occupied residential properties in close proximity on the western side of the application area. Grandcourt Farm is located north-west of the site at 75 metres from the proposed extraction area and another property also known as Grandcourt Farm (here referred to as Carrpit Cottage to avoid confusion) located next to the A47 at a distance of 100 metres from the proposed extraction area. Holland House, situated just off the A47 is the closest property to the south east of the application area at a distance of 100 metres from the proposed extraction area.

7.4.2 Grandcourt Bungalow is situated at the western edge of the application site and it is proposed that this property will, subject to mineral planning consent, be demolished.

7.4.3 A larger number of noise sensitive residential properties are located in East Winch village to the east of the application site. No.63 Town close is situated at 270m from the north eastern edge of the application area.

7.5 ENVIRONMENTAL NOISE CRITERIA

Site Specific Noise Criteria

7.5.1 For the ongoing sand extraction operations at Grandcourt Quarry, planning consent was granted by Norfolk County Council in 2007 (Planning Ref No. C/2/2004/2034). Condition 5 of the consent specifies a limit on received noise from site operations as follows:

‘With the exception of noise generated during soil movement and bund/baffle mound construction and removal, noise emitted from the site shall not exceed:

49dB(A) LEQ (1 hour) at Grandcourt Farmhouse PART TWO NOISE

50dB(A) LEQ (1 hour) at Grandcourt Bungalow

46dB(A) LEQ (1 hour) at Carrpit Cottage

National Planning Policy Framework and Technical Guidance

7.5.2 The National Planning Policy Framework (NPPF) was issued by the Department for Communities and Local Government in March 2012. The NPPF simplifies and replaces over a thousand pages of planning policy with a single, concise document.

7.5.3 The NPPF is supplemented by a Technical Guidance document which provides additional guidance to planning authorities to ensure effective implementation of the planning policy set out in the NPPF on development in relation to mineral extraction. The Technical Guidance sections relating to assessment and control of noise from proposed mineral developments are outlined below.

Noise Emissions

7.5.4 Under the National Planning Policy Framework, planning authorities need to ensure that unavoidable noise emissions are controlled, mitigated or removed at source. Planning authorities should also establish appropriate noise limits for extraction operations taking place in proximity to noise sensitive properties

7.5.5 Those making development proposals should carry out an assessment of noise emissions which should identify all noise sources and consider the proposed locations, procedures and duration of operations. Proposals for the control or mitigation of noise emissions should consider:

• the main characteristics of the operations process and its environs, including the location of noise-sensitive properties;

• proposals to minimise, mitigate or remove noise emissions at source; • assessing the existing noise climate around the site of the proposed development operations, including background noise levels at nearby noise sensitive properties; • estimating the likely future noise from the development and its impact on the neighbourhood of the proposed operations: • monitoring noise emissions to ensure compliance with appropriate environmental standards

PART TWO NOISE

Noise Standards

7.5.6 Subject to a maximum of 55dB(A) LEQ 1 Hour (free-field), Mineral Planning Authorities should aim to establish a noise limit at the noise sensitive property that does not exceed background level by more than 10dB(A). It is recognised, however that in many circumstances it will be difficult to not exceed background level by more than 10dB(A) without imposing unreasonable burdens on the mineral operator. In such cases the limit set should be as near that level as practicable during normal working hours (07:00 – 19:00) and

should not exceed 55dB(A) LEQ.

7.5.7 Evening (19:00 – 22:00) limits should not exceed background level by more than 10dB(A)

and night-time limits should not exceed 42dB(A) LEQ.

7.5.8 Where tonal noise contributes significantly to the total site noise, it may be appropriate to set specific limits for this element. Peak or impulsive noise, which may include some reversing bleepers, may also require separate limits that are independent of background noise and should not be allowed to occur regularly at night.

7.5.9 For noisy, short-term activities such as soil stripping, construction and removal of baffle/soil storage mounds and spoil heaps or construction of new permanent landforms, it may not be possible to meet the noise limits set for normal operations.

7.5.10 Increased daytime noise limits of up to 70dB(A) LEQ for periods of up to eight weeks in a year at specified noise sensitive properties should be considered for essential site preparation and restoration work where it is clear that this will bring longer term environmental benefits to the site or its environs.

7.5.11 Where work is likely to take longer than eight weeks, a lower limit over a longer period should be considered. In some wholly exceptional cases, where there is no viable alternative, a higher limit for a very limited period may be appropriate in order to attain the

environmental benefits. However, within this framework the 70dB(A) LEQ limit referred to previously should be regarded as the normal maximum.

7.6 MONITORING OF EXISTING NOISE LEVELS

7.6.1 Measurement of background/ambient noise levels has been undertaken in the vicinity of the closest noise sensitive residential properties on each side of the application site (see Figure PART TWO NOISE

7.1). The monitoring procedure and instrumentation used are set out in Appendix 7.1 and the recorded noise levels are shown in Appendix 7.2.

7.6.2 Noise monitoring was conducted at three locations over periods of twelve hours (during separate visits in May and July 2012 and March 2013) corresponding to the maximum proposed working periods. Readings were obtained over twelve consecutive one-hour periods commencing at 7:00 and ending at 19:00. Monitoring at one location was conducted over a nine hour period, commencing at 10:00 and ending at 19:00.

Town Close, East Winch

7.6.3 Town Close in East Winch is situated on the north eastern side of the application area. There are a number of residential properties on the close and noise monitoring was conducted in the back garden of No.63. Traffic on the A47 road was the most significant noise source and was audible throughout the survey period.

7.6.4 The range of one hour LEQ levels was from 52.1dB(A) to 56.8dB(A) with the highest levels

recorded around midday and early afternoon. The range of L90 levels was from 42.0dB(A) to 49.0dB(A) with the highest levels occurring between 7:00 and 9:00.

Grandcourt Farm

7.6.5 Grandcourt Farm is located at the north western edge of the application site and adjacent to the existing quarry. Although the property is situated 500 metres from the A47, road traffic is the most significant noise source, being audible as a continuous drone. Other noise sources noted during the monitoring included birdsong (almost continuous) and aircraft (intermittent).

7.6.6 The measured one hour LEQ levels were quite variable, with the lowest (46.4dB(A)) and

highest (57.4dB(A)) values recorded in consecutive hours during the afternoon. L90 levels were lowest mid-morning at 36.5dB(A), rising to 45.0dB(A) in the evening.

Carrpit Cottage

7.6.7 Carrpit Cottage is located adjacent to the A47 at the south west corner of the application area. The monitoring equipment was set up at 30 metres from the edge of the road; an

equivalent distance from the roadside as the façade of the property. Measured LEQ levels were consistently high due to the influence of road traffic, ranging from 64.1dB(A) to

66.1dB(A). L90 levels ranged between 52.0dB(A) to 57.0dB(A). A traffic count over twenty PART TWO NOISE

minutes during the afternoon gave pro-rata hourly figures of 780 cars/light goods vehicles and 117 heavy goods vehicles/buses.

Holland House

7.6.8 Holland House is a detached residential property located adjacent to the A47 at the south east corner of the application area. The monitoring equipment was set up at 17 metres from the edge of the road; an equivalent distance from the roadside as the façade of the property. Monitoring of background noise was conducted over a nine hour period

commencing at 10am. Measured LEQ levels ranging from 59.1dB(A) to 63.1dB(A) whilst L90 levels were more variable, ranging from 44.0dB(A) to 54.0dB(A).

7.6.9 Road traffic noise was again the dominant noise source. Traffic counts on the A47 were conducted at during the first and last hours of the survey and also in the early afternoon. The pro-rata hourly figures were 660 to 741 cars/light goods vehicles and 48 to 180 heavy goods vehicles/buses.

7.7 PROPOSED SITE OPERATIONS

7.7.1 Quarrying operations within the application area will employ similar methods to those which are currently taking place within the existing Grandcourt Quarry. The standard earthmoving team will typically consist of a Volvo EC700BLc hydraulic excavator, five Volvo A40 articulated dumptrucks and a Komatsu D65WX bulldozer.

Soil Removal and Screening Bund Construction

7.7.2 Soil will be excavated and loaded into articulated dumptrucks which will transfer this material to the site perimeter. A bulldozer will be used to place the soil into screening bunds of between 2.5m and 3m high, in accordance with the proposed working scheme. The screening bunds will be constructed as part of the site preparation work in advance of the main quarrying operations to ensure that the subsequent operations are fully acoustically screened. Soil from some areas of the application site may have been excavated in advance and placed into windrows within the site as part of archeological investigations.

Overburden Excavation

7.7.3 The overburden in the application site consists primarily of carrstone in thicknesses from 8m to 10m. The material will be excavated in two or three lifts and loaded into articulated PART TWO NOISE

dumptrucks. Where possible, the overburden will be transferred directly to areas of site reinstatement to minimize double handling and vehicle movements. However, some of the overburden will be placed into stockpiles for long term storage.

Sand Excavation and Haulage

7.7.4 The mineral deposit will be excavated and loaded into articulated dumptrucks for transfer to the mineral processing site at Leziate. The existing haul route with a short extension into the application site (and a modified alignment in the current quarry to facilitate restoration works) will continue to be used. Continuing use of the current haul route means that there will be no change in the noise impact from the proposed haulage activity, compared to the present. The internal haul route within the current quarry will, in fact, be further from Grandcourt Farm than at present.

Backfilling and Reinstatement

7.7.5 As indicated above, backfilling and reinstatement operations will take place concurrently with overburden excavation to allow direct transfer of the excavated material and avoid double handling where possible. The overburden will be deposited by articulated dumptruck and then graded/compacted by bulldozer into agreed profiles. On completion of the quarrying activity, the soil which is stored in screening bunds will be transferred and spread onto the restored ground.

7.8 NOISE PREDICTIONS – CALCULATION PROCEDURES

7.8.1 The methods set out in BS 5228-1:2009 – Code of Practice for noise and vibration control on construction and open sites – Part 1: Noise; have been used as a basis for the predictions of received noise. The procedures used in this noise impact assessment which are given in Annex F, are as follows:-

Determination of Sound Power Levels

7.8.2 The sound power outputs of the various noise sources in operation can be obtained from sound pressure level measurements taken during operation of the plant in comparable situations. Alternatively, the manufacturer’s rated sound power outputs for certain types of mobile plant may be used, although the figures may not represent actual operating conditions and the resultant noise emissions. PART TWO NOISE

7.8.3 The numbers, types and models of machines likely to be used in the proposed quarry extension at Grandcourt Farm are assumed to be similar those used in the existing quarrying operation.

7.8.4 Currently there is one quarrying gang in regular operation. This consists of a Volvo EC700BLc hydraulic excavator and four Volvo A40F articulated dumptrucks and a Komatsu D65WX bulldozer.

7.8.5 In order to calculate the impact of the proposed quarrying operations, sound pressure level measurements were taken in May 2012 for the mobile plant used at Grandcourt Quarry. The activities and items of mobile plant for which sound power levels have been calculated are shown below.

Backfilling and Reinstatement 1 x Komatsu D65WX bulldozer 104.4dB(A)

5 x Volvo A40F dumptrucks

Distances from Source to Receiver

7.8.6 As noise arising from the proposed tipping activities will be from mobile sources, the distances from source to receiver will be continually changing and the received noise levels will therefore fluctuate.

7.8.7 In order to assess the maximum possible impact of the workings on noise sensitive properties, calculations have been prepared based on worst case scenarios (i.e. when mobile plant is operating at the working limit adjacent to residential properties). PART TWO NOISE

Screening by Barriers

7.8.8 The presence of barriers situated between noise source and receiver will provide some attenuation of noise. In the planned quarry workings, screening will be provided by topography and by the quarry faces. The degree of attenuation due to screening will depend on the relative positions of source, barrier and receiver.

7.8.9 BS 5228 details a method to predict noise due to screening based on the calculation of path difference from source to receiver due to presence of a barrier. Spectral data for the source is used to plot the attenuation at frequencies from 125Hz to 2000Hz for the given path difference, using the graph shown in Figure F.3 of the standard. Barrier attenuation values between 5dB and 27dB can be obtained from this method

7.8.10 An alternative more general approach is to allow 5dB attenuation when the source is partially screened from the receiver position and 10dB attenuation when the source is fully screened. This method which tends to give more conservative predictions of the attenuation which can be achieved by screening has been used in calculating received noise levels within this noise impact assessment.

Soft Ground Attenuation

7.8.11 Noise propagating over soft ground will be attenuated to a greater degree than noise propagating over hard ground. The land between the application site and the nearest noise sensitive properties is primarily arable farm land and is therefore acoustically soft ground.

7.8.12 Calculation of soft or mixed hard/soft ground attenuation has been conducted following the procedures given in BS 5228. Attenuation due to soft ground has been calculated for source - receiver distances up to a maximum distance of 300m as meteorological effects introduce a significant element of uncertainty at distances greater than this.

7.8.13 In instances where barrier screening is present, no allowance has been made for soft ground attenuation as it is accepted that barriers intercept much of the noise that would otherwise be absorbed by soft ground.

PART TWO NOISE

7.9 PREDICTED NOISE IMPACT

7.9.1 Based on the assessment procedure outlined above, received noise levels have been calculated at four of the closest noise sensitive properties to the application site (Appendix 7.3).

7.9.2 The calculated received noise levels have been compared to the average of the daytime L90 values measured at each property and in all cases are predicted to be within both the

55dB(A) LEQ limit and no more than ten decibels above the existing average daytime background noise levels.

7.9.3 For the short-term activities including soil stripping and construction and removal of screening bunds, received noise levels will be higher but are predicted to remain well below

the 70dB(A) LEQ noise limit defined for these short term site preparation operations.

7.9.4 The duration of such short-term works will be phased so that it will take place for no more than eight weeks per year adjacent to the specified noise sensitive properties.

7.10 MANAGEMENT OF SITE OPERATIONS

Reversing Alarms

7.10.1 All mobile plant in use at Grandcourt Quarry is fitted with audible reversing alarms for safety purposes. Although planning noise limits do not apply to these devices, it is recognised that they are a major potential source of noise nuisance.

7.10.2 Sibelco has undertaken to address this issue by replacing the standard tonal noise alarms with ‘white noise’ alarms. The alarms emit a directional broadband noise which is designed to aid source perception when set at a lower sound pressure level. Additionally, approved contractors operating mobile plant on Sibelco sites are required to equip their machines with broadband reversing alarms.

Complaints Reporting and Investigation

7.10.3 An environmental complaints register is maintained by Sibelco and any nuisance/disturbance issues relating to site operations being logged and investigated by site management in accordance with company procedures. If site activities are shown to have caused problems, appropriate corrective/remedial measures will be implemented. PART TWO NOISE

Quarrying operations taking place at Grandcourt Quarry under the current planning consent have not generated any noise complaints. A noise monitoring and management scheme is proposed as part of the Planning Statement.

Working Hours

7.10.4 The proposed working hours for quarrying operations would be in accordance with the standard daytime periods indicated in the NPPF Technical Guidance. This should avoid any potential for sleep disturbance associated with site activity in the early morning and late evening.

Monitoring of Quarry Noise Levels

7.10.5 Periodic environmental monitoring has been undertaken at Grandcourt Quarry to assess received noise levels arising from the current quarrying operations. All survey results to date have been within the relevant limits specified in the planning consent (see Appendix 7.4 for most recent noise results).

7.11 CONCLUSIONS

7.11.1 The proposed extension of operations to extract proven high quality sand resources in land to the east of Grandcourt Quarry will involve mobile plant working in closer proximity to a number of noise sensitive residential properties. A comparison of measured background noise levels and predicted worst-case noise levels arising from the proposed development indicates that the impact will be within planning guidance standards.

7.12 GRANDCOURT QUARRY NOISE ASSESSMENT AND RESULTS

7.12.1 In the 2004 Environmental Statement for Grandcourt Farm, noise levels from the Site were predicted using the methodology of BS 5228:19974 and compared with the guidelines in the then Mineral Planning Guidance Note MPG11 (now compared to Planning Practice Guidance for minerals).

7.12.2 The noise predictions assumed the worst case scenarios, consistent with the relevant standard, including mobile plant working at full power for much of the time and operating at the closest proximity to any affected properties. In practice the noise levels will be lower as mobile plant is not static and will be at greater distances than those assumed. Noise predictions were made for: PART TWO NOISE

• Site preparation and baffle mound construction

• Overburden removal and stockpiling

• Sand extraction and transfer to Leziate processing plant

7.12.3 During this preparatory and temporary work the predicted noise levels at the farm and the

bungalow were 67 dB LAeq,1hour and 68 dB LAeq,1hour respectively. Similarly, the predicted

noise level at the dwelling on the A47 will be 64 dB LAeq,1hour, although construction of this section of baffle mound would take place some years later in the quarrying operations. MPG 11 suggested (and PPG Paragraph: 022 Reference ID: 27-022-20140306 reiterates)

a limit of 70 dB LAeq,1hour for baffle mound or bund construction for periods of up to 8 weeks in a year recognizing that this may cause some temporary inconvenience to local residents, but will lead to long term benefits. All of the predicted noise levels at the three properties under consideration were lower than this suggested limit.

7.12.4 Overburden removal was assessed to be most significant when working in the northeast sector, as there will be concurrent construction of a clay stockpile approximately 250 m north of the farmhouse and the need to transport clay from the quarry to this location. The predicted worst case noise level at Grandcourt Farm house during these works was 49 dB

LAeq,1hour. As the quarry progresses to the south overburden will be a thin layer of soil and there will be no concurrent work on stockpiles, allowing for work closer to the bungalow, the

predicted worst case noise level was 50 dB LAeq,1hour and that at the dwellings on the A47

would be below 46 dB LAeq,1hour.

7.12.5 The only noise received at Sandpit Cottage will be that during the contouring operation in the northwest sector of the site. Sandpit Cottage is over 500 m from this area of works and

the predicted worst case noise level was the low 40’s dB LAeq,1hour.

7.12.6 Sand extraction will produce similar noise levels to overburden removal, but slightly lower due to the enhanced screening due to protection by quarry faces. At this time sand will be transported off site to the Leziate processing plant and the combined effect of noise from the dump trucks on haul with the sand extraction will be very similar to the predicted noise from overburden removal.

7.12.7 MPG 11 proposed (and PPG Paragraph: 021 Reference ID: 27-021-20140306 proposes) a

limit of noise of 55 dB LAeq,1hour.

PART TWO NOISE

7.12.8 Following the former assessment and the granting of planning consent, the present Grandcourt Quarry has Condition 5 attached to consent number C/2/2004/2034 which states that

With the exception of noise generated during soil movement and bund/baffle mound construction and removal, noise emitted from the site shall not exceed:-

49 dBLAeq (1 hour) at Grandcourt Farmhouse

50 dBLAeq (1 hour) at Grandcourt Bungalow

46 dBLAeq (1 hour) at Carrpit Cottage

7.12.9 Noise monitoring results are tabulated below:-

7.12.10 Carrpit Cottage is located on the A47 and is subject to significant road noise. The property had not been occupied during the development period to the end of 2017. The marginal exceedance at Grandcourt Bungalow in November 2016 does not take account of soft ground attenuation. Operations are now further from the property and the property is unoccupied and not likely to be occupied in future.

7.12.11 The noise results show compliance with the noise condition and with national noise guidance for mineral operations.

7.12.12 Operations at Grandcourt Quarry have already been undertaken at the closest proximity to Grandcourt Farm and Carrpit Cottage (see Figure 7.1). Grandcourt Bungalow is now remaining unoccupied. Previous workings at Grandcourt Quarry were within 75 metres of Grandcourt Farm and are presently some 400 to 500 metres distant. Future permitted PART TWO NOISE

workings in Grandcourt Quarry will be between 500 metres and 1.2 km from Grandcourt Farm.

7.2.13 Previous workings at Grandcourt Quarry were within 55 metres of Carrpit Cottage and are presently some 100 to 300 metres distant. Future permitted workings in Grandcourt Quarry will be between 300 metres and 1.3 km from Carrpit Cottage.

7.2.14 The increasing distances of the active quarry areas now from the properties is reflected in the most recent noise results which are significantly below permitted levels. Activities in the current permitted quarry area will increase still further from these three properties over the life of the site. KEY 568400 568600 568800 569000 569200 569400

APPENDIX 7.1 AMBIENT/BACKGROUND NOISE LEVEL MONITORING EQUIPMENT AND PROCEDURES

APPENDIX 7.1 – AMBIENT/BACKGROUND NOISE LEVEL MONITORING EQUIPMENT AND PROCEDURES

NOISE MONITORING PROCEDURE Noise measurements were conducted at four locations adjacent to the closest noise sensitive properties to the application site. Sound pressure level measurements were taken between 7:00 and 19:00 to assess existing background noise levels during the proposed working period.

At each monitoring location the equipment was set up with the microphone at between 1.3 and 1.5 metres above ground level and at a minimum distance of five metres from vertical reflecting surfaces.

The sound level meter was programmed to measure and record the following parameters in both dB (linear) and dB(A) over consecutive one-hour periods.

Leq - equivalent continuous noise level averaged over whole period L10 - noise level exceed for 1% of measurement interval L50 - noise level exceeds for 10% of measurement interval L90 - noise level exceeds for 50% of measurement interval L95 - noise level exceeds for 90% of measurement interval L99 - noise level exceeds for 99% of measurement interval Lmax - maximum sound pressure level in measurement interval

A CEL 593.C1 type 1 sound level meter was used to measure environmental sound pressure levels. The instrument was programmed with a fast time-weighting and a dynamic range from 25 to 100 dB. A free-field response microphone setting was used for all measurements.

The sound level meter was contained within a weatherproof case along with a twelve volt power supply and connected to the preamplifier and microphone via ten metre digital extension cable.

A windshield, rain cage and bird spike were used to protect the microphone and preamplifier. A survey sheet detailing the monitoring location and instrument settings was completed for each survey period.

Weather observations were noted and measurements of wind velocity and air temperature were measured using a Testo 425 Thermo-Anemometer. Atmospheric pressure was recorded using a Suunto Digital Barometer and relative humidity was measured using a Casella aspirated psychrometer. The grid references of the monitoring locations were established using Garmin e-Trex Legend or Garmin Dakota 20 GPS receivers.

The noise monitoring equipment was calibrated using a CEL 284/2 acoustical calibrator at the start and end of each survey period to identify any drift in values.

Environmental noise monitoring was carried at Kings Lynn Quarry, Norfolk, Grandcourt Farm Area, on the 17th June 2016.

The calculated LAeq,1hr measurements at Grandcourt Farmhouse, Grandcourt Bungalow and Carrpit Cottage were found to be below the permitted noise levels set within Grandcourt Quarry consent number C/2/2004/2034 dated 7th September 2007 with screening attenuation taken into account.

1 INTRODUCTION

1.1 ESG was requested by Mr S Ford, Sibelco Europe to undertake an environmental noise survey at Kings Lynn Quarry, Norfolk, Grandcourt Farm Area.

1.2 Monitoring was carried out on the 17th April 2016, at one location within the Grandcourt quarry . The quarry was undertaking normal operations during the monitoring period, which includes:

 Face operations, 1 x Volvo 360 excavator loading five Volvo A30E loading shovels which are transporting sand from face to central stock piles.

1.3 Monitoring was carried out by Robert Preston, Occupational Hygiene Technologist, ESG.

2 SCOPE AND EXCLUSIONS

2.1 The survey was required to monitor the levels of environmental noise at the nearest noise sensitive receptors and compare with permitted noise levels specified within the Grandcourt Quarry consent number C/2/2004/2034 dated 7th September 2007.

2.2 The permitted noise levels are as follows:

Permitted LOCATION: Noise Level dBLAeq (1hour) 1 Grandcourt Farmhouse 49 2 Grandcourt Bungalow 50 3 Carrpit Cottage 46

3 BACKGROUND INFORMATION

3.1 The nature of the response to noise can vary widely between individuals from no response at all to disturbance that can develop into annoyance or anger. Some individuals may experience physical effects arising as a result of emotional stress, such as sleep disturbance or loss of appetite.

3.2 The effects of noise are made up of two components - its energy (an objective component) and its tendency to annoy (a subjective component which differs according to the noise source). Thus noise has a plethora of measurement units, supported to varying degrees by social survey data establishing they’re subjective, annoyance factors. All this reflects the fact that, in general, noise affects people rather than the environment itself.

16_06_040774-1_RP_01 Page 4 of 14 3.3 A survey of environmental noise, published in 1993 by the Building Research Establishment (BRE), revealed that 56% of individual homes were exposed to daytime noise levels in excess of the levels recommended by the World Health Organisation (WHO) to prevent significant community annoyance. The survey showed that:

 At night 63% of the population is exposed to noise levels exceeding those which WHO claim are desirable to meet sleep criteria.

 Traffic noise was noticeable outside over 90% of dwellings, although only 5% face main roads. Aircraft were heard at more than 60% of homes.

3.4 Noise is a significant environmental pollutant, with complaints to local authorities on neighbour noise rising four-fold between 1984 and 1994, and similar notable rises about other noise sources such as construct and road noise.

4 MONITORING METHODS

4.1 See Appendix A – Methods for the test method and equipment used.

4.2 The sound level meter microphone was equipped with a windshield at all times and the following parameters were set on the sound level meter during the noise measurements:

Time weighting: Fast Frequency weighting: A Logging Intervals: 5 minute Parameters: LAeq; LAmax; LA10; LA90 (dB)

4.3 All readings taken were “free field”, i.e. at least 3.5m away from any facade or reflecting surface other than the ground. The microphone was located 1.2 to 1.5m above ground level.

4.4 British Standard BS4142:1997/2014 defines weather conditions for environmental noise surveys as mean wind speed less than 5 ms-1 and no significant rainfall.

4.5 The LEQ levels calculated for each property, arising from quarrying noise sources are listed in the results section.

4.6 The procedure to assess received noise levels, which has been agreed with Sibelco Europe, involves measurement of noise levels close to each sound source and calculation of total noise levels received at each property allowing for attenuation due to distance and screening.

16_06_040774-1_RP_01 Page 5 of 14

4.7 Received noise levels from each activity have been calculated using normal hemispherical propagation from either a point or line source making a nominal allowance of -5 dB(A) or -10 dB(A) for barrier attenuation as described in BS5228:1997 – Noise and Vibration Control on Open Construction Sites.

4.8 ESG personnel were present throughout the monitoring period, thereby ensuring that an accurate representation of the prevailing noise climate was recorded.

5 RESULTS

The measurement taken is shown below. A plan showing the measurement locations and receptor positions can be found in Appendix C.

The main noise sources at this location were engine and reversing sirens from excavator and five loading shovels.

5.2 The following weather conditions were recorded during the survey:-

Overcast, dry, 52% Cloud cover, Wind N 8mph (< 5 ms-1) 17 June 2016 Temp 16oC.

This satisfied the conditions defined in British Standard BS4142:1997/2014.

6 DISCUSSION

6.1 Environmental noise monitoring was carried out in one area Kings Lynn Quarry, Norfolk, Grandcourt Farm Area where significant quarrying activity was taking place.

6.2 The calculated LAeq,1hr measurements at Grandcourt Farmhouse, Grandcourt Bungalow and Carrpit Cottage were found to be below the permitted noise levels set within Grandcourt Quarry consent number C/2/2004/2034 dated 7th September 2007 with screening attenuation taken into account.

6.3 The main contributors to the noise climate throughout the monitoring period were as follows:

 Engine and reversing sirens from excavator and five loading shovels.

7 CONCLUSIONS & RECOMMENDATIONS

7.1 The results of the survey indicated that the calculated LAeq,1hr at all of the specified locations were below the respective specified limit during the monitoring period.

7.2 In addition to the 3m high top soil bunding observed at each of the three locations; the working level of the excavator was approximately 10 metres below ground level at the receptors locations. As a result additional screening was offered by the quarry faces. Further attenuation was also offered by the top soil windbreaks designed to minimise fugitive dust from site. During a walk to the Carpitt cottage location it was noted that quarry operations were not audible at this location as a result of the aforementioned bunding and also the A47 road noise. During a brief period when road noise was not present the quarrying operations were still not audible at Carpitt cottage.

7.3 The following ‘good housekeeping’ measures should continue to be considered when quarry operations are carried out on site to ensure that noise levels emanating from site are kept to a minimum:

 Ensure that inspection plates and any acoustic panels on mobile and static plant are in place and fitted correctly.

 Repair or replace any defective exhaust systems on mobile plant (i.e. missing clamps or locating pins) as soon as possible after any defects are discovered.

 Ensure that mobile plant is driven and operated correctly, and that all site speed limits are properly observed.

16_06_040774-1_RP_01 Page 8 of 14

 Inspect the equipment used on site to ensure it is not damaged or requiring maintenance.

1 INTRODUCTION

1.1 ESG was requested by Mr S Ford, Sibelco Europe to undertake an environmental noise survey at Kings Lynn Quarry, Norfolk, Grandcourt Farm Area.

1.2 Monitoring was carried out on the 16th November 2016, at one location within the Grandcourt quarry . The quarry was undertaking normal operations during the monitoring period, which includes:

 Face operations, 1 x Volvo 360 excavator loading five Volvo A30E loading shovels which are transporting sand from face to central stock piles.

1.3 Monitoring was carried out by Robert Preston, Occupational Hygiene Technologist, ESG.

2 SCOPE AND EXCLUSIONS

2.2 The permitted noise levels are as follows:

Permitted LOCATION: Noise Level dBLAeq (1hour) 1 Grandcourt Farmhouse 49 2 Grandcourt Bungalow 50 3 Carrpit Cottage 46

3 BACKGROUND INFORMATION

16_11_040774-2_RP_01 Page 4 of 12 3.3 A survey of environmental noise, published in 1993 by the Building Research Establishment (BRE), revealed that 56% of individual homes were exposed to daytime noise levels in excess of the levels recommended by the World Health Organisation (WHO) to prevent significant community annoyance. The survey showed that:

 At night 63% of the population is exposed to noise levels exceeding those which WHO claim are desirable to meet sleep criteria.

 Traffic noise was noticeable outside over 90% of dwellings, although only 5% face main roads. Aircraft were heard at more than 60% of homes.

4 MONITORING METHODS

4.1 See Appendix A – Methods for the test method and equipment used.

4.2 The sound level meter microphone was equipped with a windshield at all times and the following parameters were set on the sound level meter during the noise measurements:

Time weighting: Fast Frequency weighting: A Logging Intervals: 5 minute Parameters: LAeq; LAmax; LA10; LA90 (dB)

4.3 All readings taken were “free field”, i.e. at least 3.5m away from any facade or reflecting surface other than the ground. The microphone was located 1.2 to 1.5m above ground level.

4.4 British Standard BS4142:1997/2014 defines weather conditions for environmental noise surveys as mean wind speed less than 5 ms-1 and no significant rainfall.

4.5 The LEQ levels calculated for each property, arising from quarrying noise sources are listed in the results section.

16_11_040774-2_RP_01 Page 5 of 12 4.7 Received noise levels from each activity have been calculated using normal hemispherical propagation from either a point or line source making a nominal allowance of -5 dB(A) or -10 dB(A) for barrier attenuation as described in BS5228:1997 – Noise and Vibration Control on Open Construction Sites.

4.8 ESG personnel were present throughout the monitoring period, thereby ensuring that an accurate representation of the prevailing noise climate was recorded.

5 RESULTS

The measurement taken is shown below. A plan showing the measurement locations and receptor positions can be found in Appendix C.

6 DISCUSSION

6.1 Environmental noise monitoring was carried out in one area of Kings Lynn Quarry, Norfolk, Grandcourt Farm Area where significant quarrying activity was taking place.

6.3 The main contributors to the noise climate throughout the monitoring period were as follows:

 Engine and reversing sirens from excavator and four loading shovels.

7 CONCLUSIONS & RECOMMENDATIONS

7.1 The results of the survey indicated that the calculated LAeq,1hr at all of the specified locations were below the respective specified limit during the monitoring period.

 Ensure that inspection plates and any acoustic panels on mobile and static plant are in place and fitted correctly.

 Repair or replace any defective exhaust systems on mobile plant (i.e. missing clamps or locating pins) as soon as possible after any defects are discovered.

 Ensure that mobile plant is driven and operated correctly, and that all site speed limits are properly observed.
