Modelling results assume all plant for a given activity operate at the same location, at the shortest distance from each receptor Corridor Provided by Western Power Distribution as of 6th October 2014 Layout Terrain In absence of terrain data the site and surrounding area is assumed to be flat at 0m. This is considered to be reasonable assumptions and reflects the observed change in terrain on and around the site. Screening No screening (i.e. buildings, structures, walls) are included within the noise model.

1 Introduction

1.1.1 RSK Environment Limited (RSK) was commissioned by Western Power Distribution Ltd (WPD) to carry out an air quality impact assessment in support of the EIA for the Brechfa Forest Connection (Proposed Development).

1.1.2 This study forms Appendix 15.1 of Chapter 15 of the Environmental Impact Assessment, and should be read in conjunction with that chapter.

1.1.3 The purpose of this document is to summarise the air quality assessment method and assessment results for the construction phase of the Proposed Development and identify appropriate mitigation measures. Sections in this document describe the:

. Air quality baseline;

. Scope and methodology;

. Air quality assessment; and

. Recommended mitigation measures

Appendix 15.1: Air Quality Technical Appendix – Volume 3

2 Air quality baseline

2.1 Introduction

2.1.1 This section sets out the air quality baseline relevant to the Proposed Development.

2.2 Key Legislation

2.2.1 UK air quality policy is published under the umbrella of the Environment Act 1995, Part IV and specifically Section 80, the National Air Quality Strategy (NAQS). The latest Air Quality Strategy for England, Scotland, Wales and Northern Ireland – Working Together for Clean Air, published in July 2007 sets air quality standards and objectives for ten key air pollutants to be achieved between 2003 and 2020.

2.2.2 The EU Air Quality Framework Directive (1996) established a framework under which the EU could set limit or target values for specified pollutants. The directive identified several pollutants for which limit or target values have been, or will be set in subsequent ‘daughter directives’. The framework and daughter directives were consolidated by Directive 2008/50/EC on Ambient Air Quality and Cleaner Air for Europe, which retains the existing air quality standards and introduces new

objectives for fine particulates (PM2.5).

2.2.3 These objectives are used in the review and assessment of air quality by local authorities under Section 82 of the Environment Act (1995). If exceedances of any of these objectives are measured or predicted through the review and assessment process, the local authority must declare an air quality management area (AQMA) under Section 83 of the act, and produce an air quality action plan (AQAP) to outline how air quality is to be improved to meet the objectives in the designated AQMA, under Section 84 of the act.

2.2.4 The key air pollutants of relevance to the local air quality management are

nitrogen dioxide (NO2) and fine particulate matter (PM10).

Appendix 15.1: Air Quality Technical Appendix – Volume 3

Table 1: Relevant Air Quality Objectives

Exceedances Ground level Substance Averaging period allowed per concentration year limit (g/m3)

1 calendar year - 40 Nitrogen dioxide (NO2) 1 hour 18 200

1 calendar year - 40 Fine particles (PM10) 24 hours 35 50

2.3 Existing ‘Baseline’ Air Quality

2.3.1 Existing or baseline air quality refers to the concentrations of relevant substances that are already present in ambient air. These substances are emitted by various sources, including road traffic, industrial, domestic, agricultural and natural sources. Baseline air quality data employed in this study have been obtained from diffusion tube monitoring locations maintained by CCC, and from the LAQM website operated by DEFRA.

Local Authority review and assessment of air quality

2.3.2 As directed by the Environment Act 1995, local authorities are required to review and assess air quality with respect to the standards and objectives for the pollutants specified in the Government’s National Air Quality Strategy (NAQS, 2007). Where objectives are not predicted to be met, local authorities must declare an AQMA and prepare an AQAP, which aims to improve air quality within the designated AQMA.

2.3.3 CCC has declared one AQMA within the council area. The Llandeilo AQMA was declared in 2011 and is for exceedances of the annual mean nitrogen dioxide

(NO2) objective. This AQMA is approximately 10 km from the Proposed Development.

Baseline monitoring data

Appendix 15.1: Air Quality Technical Appendix – Volume 3

2.3.4 There are no automatic air quality monitoring stations within the jurisdiction of

CCC. However, there are six NO2 diffusion tube sites, at a mixture of roadside and background monitoring locations. These tubes are located within 2km of the Proposed Development.

2.3.5 The 2012 and 2013 annual average measured NO2 concentrations obtained from CCC are reproduced in Table 2. There were exceedances of the annual mean

objective for NO2 at some of the monitoring locations in 2012 and 2013.

LAQM background data

2.3.6 In the absence of appropriate measured air quality data along the Proposed

Appendix 15.1: Air Quality Technical Appendix – Volume 3

Development, estimated background data available from the Local Air Quality Management (LAQM) Support website operated by Defra have been used.

2.3.7 The LAQM website provides estimated annual average background 2 concentrations of nitrogen oxides (NOx), NO2 and PM10 on a 1 km grid basis.

2 2.3.8 The 1 km grid squares have been identified for the project and are shown in Figure 15.1. The estimated annual average pollutant concentrations for each of these 1 km2 grid squares are shown in Table 3. The numbers for each square identified in the figure are replicated in the table.

2.3.9 Table 3 shows that that there are no exceedances of any air quality objectives predicted at ‘background’ locations along the Proposed Development, with all concentrations being well below the annual average objective limits.

3 Scope and methodology

3.1 Introduction

3.1.1 This section outlines the scope and methodology of the air quality assessment.

3.1.2 A qualitative assessment of the effects of the construction works on air quality has been carried out with reference to the Institute of Air Quality Management’s (IAQM) (2014) Guidance on the assessment of dust from demolition and construction.

3.1.3 The construction dust assessment looks at the baseline air quality, the potential impacts, the assessment of the risk of dust impacts, and it determines appropriate site-specific mitigation.

3.2 Study Area

3.2.1 The study area for the construction dust assessment has been derived according to the Institute of Air Quality Management (IAQM) guidance.

3.2.2 Figure 15.1 shows the Limit of Deviation for the Proposed Development, with 20m, 50m, 100m and 350m ‘buffer’ areas for potential sensitive receptors and ecological sites. These 'buffers’ have been derived from the IAQM guidance.

3.2.3 This area was identified based on the individual construction and transport information available for the project, in particular Chapter 2 Project Description and all temporary and permanent works proposed.

3.2.4 Construction elements and types of works taking place in the area have been considered.

3.3 Baseline data sources

3.3.1 Existing or baseline air quality refers to the concentrations of relevant substances that are already present in ambient air. These substances are emitted by various

Appendix 15.1: Air Quality Technical Appendix – Volume 3

sources, including road traffic, industrial, domestic, agricultural and natural sources. Baseline air quality is discussed in Section 2 of this document.

3.3.2 Baseline air quality can be considered to be the ‘do nothing’ scenario.

3.4 Assessment criteria and assessment of significance

3.4.1 An assessment has been made of the significance of effect, taking into account the sensitivity of the receptor, the magnitude of impact, the duration of the impact and the likelihood of the impact occurring. The criteria that have been used to make judgements on these matters are presented below.

Traffic assessment methodology

3.4.2 It has been agreed with CCC that the Proposed Development is not expected to generate significant amount of road traffic during the construction phase. Hence no assessment of the traffic emissions is included.

Construction dust assessment methodology

3.4.3 The construction dust assessment includes recommendations for mitigation of potential emissions from vehicles and machinery operation on site.

3.4.4 To assess the potential dust impacts, construction activities are divided into four categories for assessment, which are demolition, earthworks, construction and ‘track-out’ (the tendency for vehicles leaving sites to deposit material on roads near to the site). The descriptors included in this section are based upon the IAQM guidance. The assessment follows the steps recommended in the guidance.

3.4.5 Step 1 and Step 2 methods from the IAQM guidance are described here, to assign dust risk categories for each of the construction activities.

3.4.6 The tendency of dust to remain airborne is determined by the particle size and weather conditions. Eventually, particles will drop from suspension as a deposit. The previous Local Air Quality Management Technical Guidance document

(LAQM.TG(03)) identifies that PM10 concentrations fall-off rapidly with distance

Appendix 15.1: Air Quality Technical Appendix – Volume 3

from source. Figure 1 shows the fall-off in PM10 concentration from source for a

typical wind speed of 6m/s. At 100m from source, the PM10 concentration is predicted to be less than 20% of that at the point of generation.

Figure 1: Typical Fall-off in PM10 Concentration with Distance from Source

Step 1: Screen the requirement for assessment

3.4.7 The first step is to screen the requirement for a dust assessment. This is usually a somewhat conservative level of screening. An assessment is usually required where there is:

3.4.8 A ‘human receptor’ within:

. 350m of the boundary of the site; or

. 50m of the route used by construction vehicles on the public highway, up to

Appendix 15.1: Air Quality Technical Appendix – Volume 3

500m from the site entrance(s).

3.4.9 An ‘ecological receptor’ within:

. 50m of the boundary of the site; or

. 50m of the route(s) used by construction vehicles on the public highway, up to 500m from the site entrance(s).

3.4.10 A receptor is a location that may be affected by dust emissions, human receptors include locations where people spend time and where property may be impacted by airborne dust or dust soiling. Ecological receptors are habitats that might be sensitive to dust.

3.4.11 Based on the sensitivities assigned for the different types of receptors surrounding the proposed development site and numbers of receptors within certain distances of the site (20m, 50m, 100m, 350m), a sensitivity classification for the area can be defined.

3.4.12 As there are human and ecological receptors identified within 350m of the Proposed Development, there is deemed to be a requirement for an air quality assessment.

Step 2A: Defining the potential dust emission magnitude

3.4.13 For the Proposed Development, activities will occur in the following order:

. Track-out;

. Earthworks; and

. Construction.

Track-out

3.4.14 Track-out is defined in the IAQM guidance as the transport of dust and dirt from the works site onto the public road network, where it may be deposited and then

Appendix 15.1: Air Quality Technical Appendix – Volume 3

re-suspended by other vehicles. This can arise when heavy duty vehicles leave the site with dusty material which may spill onto the road, or by the transfer of dust and dirt onto the road network following travelling over muddy ground on site.

3.4.15 Track-out for the Proposed Development may occur along any roads onto which vehicles or plant exit a works area in particular along those designated haul routes from construction compounds.

3.4.16 Factors which determine the dust emission magnitude class of track-out activities are vehicle size, vehicle speed, vehicle number, geology and duration. Examples of the potential dust emission magnitudes (or classes) are provided in the guidance as follows:

. Large: >100 HDV (3.5t) trips in any one day, potentially dusty surface material (e.g. high clay content), unpaved road length >100m;

. Medium: 25 – 100 HDV (>3.5t) trips in any one day, moderately dusty surface material (e.g. high clay content), unpaved road length 50 – 100m; and,

. Small: <25 HDV (<3.5t) trips in any one day, surface material with low potential for dust release, unpaved road length <50m.

Earthworks

3.4.17 Earthworks are processes such as soil-stripping, ground-levelling, excavation and landscaping, all of which are likely to take place along the Proposed Development.

3.4.18 The dust emission magnitude category for earthworks is varied for each site in terms of timing, geology, topography and duration. Examples of the potential dust emission magnitudes (or classes) are provided in the guidance as follows:

. Large: Total site area >10,000m2, potentially dusty soil type (e.g. clay), >10 heavy earth moving vehicles active at any one time, formation of bunds >8m in height, total material moved >100,000 tonnes;

. Medium: Total site area 2,500 – 10,000m2, moderately dusty soil type (e.g.

Appendix 15.1: Air Quality Technical Appendix – Volume 3

silt), 5 – 10 heavy earth moving vehicles active at any one time, formation of bunds 4 – 8m in height, total material moved 20,000 – 100,000 tonnes; and,

. Small: Total site area < 2,500m2, soil type with large grain size (e.g. sand), <5 heavy earth moving vehicles active at any one time, formation of bunds <4m in height, total material moved <10,000 tonnes, earthworks during wetter months.

Construction

3.4.19 Construction works include the provision of new structure, structure modifications or refurbishment.

3.4.20 With regard to the Proposed Development, construction works are considered to include the construction of open cut trenching works and Horizontal Directional Drilling (HDD).

3.4.21 The dust emission magnitude category for construction is varied for each site in terms of timing, building type, duration, and scale. Examples of the potential dust emission magnitudes (or classes) are provided in the guidance as follows:

. Large: Total building volume >100,000m3, piling, on site concrete batching;

. Medium: Total building volume 25,000 – 100,000m3, potentially dusty construction material (e.g. concrete), piling, on site concrete batching; and,

. Small: Total building volume <25,000m3, construction material with low potential for dust release (e.g. metal cladding or timber).

Demolition

3.4.22 The Proposed Development does not include demolition of any structures. Hence this activity is not included in the assessment.

Step 2B: Defining the sensitivity of the area

3.4.23 The sensitivity of the area is defined for dust soiling, human health and ecosystems. The sensitivity of the area takes into account the following factors:

Appendix 15.1: Air Quality Technical Appendix – Volume 3

. The specific sensitivities of receptors in the area;

. The proximity and number of those receptors;

. In the case of PM10, the local background concentration; and,

. Site-specific factors, such as whether there are natural shelters such as trees, to reduce the risk of wind-blown dust.

3.4.24 Table 4 provides guidance on the sensitivity of different types of receptor to dust soiling, health effects and ecological effects.

of the land.

Examples include playing fields, farmland (unless commercially-sensitive horticultural), footpaths, short term car parks and roads.

3.4.25 Tables 5 to 7 show how the sensitivity of the area may be determined for dust soiling, human health and ecosystem impacts respectively. They take into account the number of factors which may influence the sensitivity of the area.

3.4.26 The sensitivity of the area should be derived for each of the three activities (construction, earthworks and track-out).

3.4.27 It should be noted that distances to the dust source may vary with activity and so a different area may be affected by track-out than by on-site works. For track-out, as per the guidance, it is only considered necessary to consider track-out impacts up to 50m from the edge of the road.

3.4.28 Based on the sensitivities assigned for the different types of receptors surrounding the site and number of receptors within certain distances of the site, a sensitivity classification for the area can be defined. The highest level of sensitivity should be determined and recorded.

3.4.29 These tables are prescriptive and professional judgement has been used to determine the sensitivity categories, alongside information such as receptor numbers.

Step 2C: Defining the risk of impacts

3.4.30 The final step is to use both the dust emission magnitude classification with the sensitivity of the area, to determine a potential risk of impacts for each

Appendix 15.1: Air Quality Technical Appendix – Volume 3

construction activity, before the application of mitigation. Tables 8 and 9 indicate the method used to assign the level of risk for each construction activity.

3.4.31 The risk of dust impacts for each activity (earthworks, construction, and track-out) is therefore identified for the Proposed Development, based on the sensitivity of the area and dust emission magnitude. The level of mitigation recommended for each activity is then determined, and this is commensurate with the identified risk (High, Medium, or Low risk). A ‘Negligible’ category is also used, however mitigation is not required for ‘Negligible’ risk category activities.

Appendix 15.1: Air Quality Technical Appendix – Volume 3

4 Environmental assessment

4.1 Environmental assessment: construction phase

4.1.1 Atmospheric emissions from construction activities depend on a combination of the potential for emissions (the type of activity and prevailing conditions) and the effectiveness of control measures.

4.1.2 Construction activities associated with the Proposed Development may give rise to dust emissions, although these will likely be temporary in nature and restricted to areas close to construction activity.

4.1.3 The potential for fugitive dust is most likely to arise from the movement of vehicles over soil, topsoil stripping, trench digging, storage of excavated subsoil, material transfers to and from lorries, material spills during transportation and handling, particularly during prolonged periods of dry weather.

4.1.4 Construction traffic leaving the site may also bear dust and mud from the working areas which can be spread as vehicles move along the local highway network, which is known as track-out.

4.1.5 Fugitive dust emissions arising from construction activities are likely to be variable in nature and will depend upon the type and extent of the activity, soil type and moisture, road surface conditions and weather conditions. Periods of dry weather combined with higher than average wind speeds have a higher potential to generate dust.

4.1.6 Construction activities that are considered to be the most significant potential sources of fugitive dust emissions are earthworks, construction, and track-out.

Construction phase dust impact assessment

4.1.7 With reference to the IAQM guidance criteria outlined in the methodology, the dust emissions magnitude for the Proposed Development for all activities (earthworks,

Appendix 15.1: Air Quality Technical Appendix – Volume 3

construction and track-out activities) are summarised in Tables 10 to 13. There are no impacts associated with demolition, as there is no demolition planned as part of the Proposed Development.

4.1.8 Heavy vehicle numbers have been determined from the Chapter 16 ‘Transport Assessment’; precautionary ‘worst case’ figures have been used.

Sensitivity of the area

4.1.9 As per the IAQM Guidance, the sensitivity of the area takes into account a number of factors, including:

. The specific sensitivities of receptors in the area;

. The proximity and number of those receptors;

. In the case of PM10, the local background concentration; and,

. Site specific factors, such as whether there are natural shelters, such as trees, to reduce the risk of wind-blown dust.

4.1.10 Based on IAQM guidance, sensitivity of people to dust soiling and health effects of

PM10 has been given a ‘high’ rating as there are residential receptors in close proximity to the site boundary. Sensitivity of receptors to ecological effects has been given a ‘high’ rating due to the existing SAC (River Towy) within the site boundary.

4.1.11 Consideration is given to the presence of human and ecological receptors while assessing the potential impacts from construction activities within the site boundary and track-out on the road network. Where track-out route is not yet known a conservative view on the likely route has been taken, which has, for example, looked at routes in all directions along the public network.

Appendix 15.1: Air Quality Technical Appendix – Volume 3

4.1.12 Caravan parks, footpaths and public rights of ways (PROW) are also considered, and have been taken into account as human receptors, as a worst case assessment.

4.1.13 The public rights of way which have been included are all of those within 100m of the Limit of Deviation of the Proposed Development. Seven of the 1km2 grid squares have been identified within which a public right of way is located.

4.1.14 It is considered that all human receptors are ‘high sensitivity receptors’ in terms of

dust soiling and health effects of PM10, as a precautionary assumption.

4.1.15 Figure 15.1 shows a map indicating the construction and track-out buffers for identifying the sensitivity of the area.

2 4.1.16 Table 14 identifies the number of human receptors by study area and 1km grid squares and Table 15 identifies the human receptors associated with track-out.

4.1.17 Human receptors were identified by interrogating a GIS linked address database including the National Land and Property Gazetteer (NLPG), Ordnance Survey’s OS MasterMap Address Layer and the Royal Mail Postcode Address File (PAF).

4.1.18 Ecological receptors were identified by Natural Resources Wales.

4.1.19 The River Towy (SAC and SSSI) is included here as an ecological receptor.

4.1.20 For the Proposed Development there is one human receptor within 20m of the site boundary, 2 receptors within 100m, and 1 ecological receptor (River Towy) within 20m.

Summary of the sensitivity of the area

4.1.21 The overall sensitivity of the Proposed Development is summarised in Table 16.

Summary of the risk of impacts

4.1.22 Looking at the defined sensitivity of each study area along with the determined dust emissions magnitude for each construction activity, the risk of dust impacts can be defined for the Proposed Development. These are shown in Table 17.

Table 17: Summary of the risk of dust impacts for the construction phase for the Proposed Development

Potential Impact Earthworks Construction Track-out

Dust Soiling Medium Low Medium

Human Health Low Negligible Low

Ecological High Low High

4.1.23 The risk of dust impacts shows that the highest risk category for the Proposed Development is ‘High Risk’ for Earthworks and Track-out, with a ‘Low Risk’ for Construction.

4.1.24 Nevertheless, it is recognised that the above assessment has been extremely precautionary and that given a more detailed appraisal of site-specific conditions and characteristics of the Proposed Development it can be concluded that the risk of dust impacts would be far less, for the following reasons:

. In situ soil conditions are expected to be wet/ moist such that there would be a low probability of dust formation due to earthworks (e.g. trenching);

. Actual area of the site being actively worked at any one time would place the earthworks site in the ‘small’ site category rather than the ‘large’ site category and hence would entail a lesser risk of dust arising;

. The very small number of site vehicles and equipment in use at any one time;

. Despite the nearby presence of the River Towy, which is classed as a highly sensitive receptor (as it is a SAC and SSSI), this ecological receptor is not

Appendix 15.1: Air Quality Technical Appendix – Volume 3

considered to be sensitive to dust impacts as the water flow would dilute and quickly remove any dust deposition.

4.1.25 The dust risk categories determined for the Proposed Development, have been used to define the appropriate, site specific mitigation measures to be adopted. In this instance, professional judgement has been used, in accordance with the IAQM Guidance, to determine suitable and appropriate measures, which are outlined in Section 5 of this document. These are the further mitigation measures in addition to the embedded mitigation measures discussed in Section 15.4.23 of Chapter 15.

4.1.26 With the recommended mitigation in place, the construction impacts are considered to be ‘not significant’ with ‘negligible’ residual effects.

Construction traffic air quality impacts

4.1.27 The traffic predicted to be generated by the construction phase of the Proposed Development has been considered to be ‘insignificant’. Hence it has been agreed with CCC that traffic impacts during the construction phase are not included in this assessment.

4.2 Environmental assessment: operational phase

4.2.1 It is not considered that there will be any significant air emissions arising from the operational phase of the Proposed Development, and as agreed during the scoping stage, this has not been assessed further.

Appendix 15.1: Air Quality Technical Appendix – Volume 3

5 Site-Specific Further Mitigation measures

5.1.1 Site-specific further mitigation measures are divided into general measures, applicable to all sites and measures specific to earthworks, construction and track- out. Depending on the level of risk assigned to each site, different mitigation is assigned. The method of assigning mitigation measures as detailed in the IAQM guidance has been used. Demolition is not proposed so no related mitigation measures are included.

5.1.2 For those mitigation measures that are general, the highest risk has been applied. In this case, the ‘high risk’ site mitigation measures have been applied, as determined by the dust risk assessment in Section 5.1. There are two categories of mitigation measure – ‘highly recommended’ and ‘desirable’, which are indicated according to the dust risk level identified in Table 17. Desirable measures are presented in italics.

Dust management

. Develop and implement a Dust Management Plan (DMP), which may include measures to control other emissions, approved by the Local Authority. The DMP may include monitoring of dust and/ or visual inspections during periods when weather conditions are conducive to dust generation and dispersal.

Site Management

. Record all dust and air quality complaints, identify cause(s), take appropriate measures to reduce emissions in a timely manner, and record the measures taken.

. Make the complaints log available to the local authority when asked.

Monitoring

. Undertake daily on-site and off-site inspection, where receptors (including

Appendix 15.1: Air Quality Technical Appendix – Volume 3

roads) are nearby, to monitor dust, record inspection results, and make the log available to the local authority when asked.

. Carry out regular site inspections to monitor compliance with the dust management plan, record inspection results, and make an inspection log available to the local authority when asked.

. Keep site fencing, barriers and scaffolding clean using wet methods.

. Remove materials that have a potential to produce dust from site as soon as possible

. Cover stockpiles to prevent wind whipping

Preparing and maintaining the site

. Plan site layout so that machinery and dust causing activities are located away from receptors, as far as is possible.

. Avoid site runoff of water or mud.

Operating Vehicles/ Machinery and Sustainable Travel

. Ensure all vehicles switch off engines when stationary - no idling vehicles.

Operations

. Only use cutting, grinding or sawing equipment fitted or in conjunction with suitable dust suppression techniques such as water sprays or local extraction, e.g. suitable local exhaust ventilation systems.

. Ensure an adequate water supply on the site for effective dust/ particulate matter suppression/ mitigation, using non-potable water where possible and appropriate.

Waste Management

. No bonfires or burning of waste material.

Appendix 15.1: Air Quality Technical Appendix – Volume 3

Specific to earthworks

. Re-vegetate earthworks and exposed areas/ soil stockpiles to stabilise surfaces as soon as practicable.

Specific to track-out

. Use water-assisted dust sweeper(s) where appropriate on the access and local roads, to remove, as necessary, any material tracked out of the site.

. Avoid any dry sweeping of large areas.

. Ensure vehicles entering and leaving sites are covered to prevent escape of materials during transport.

. Inspect on-site haul routes for integrity and instigate necessary repairs to the surface as soon as reasonably practicable.

. Record all inspections of haul routes and any subsequent action in a site log book.

. Implement a wheel washing system (with rumble grids to dislodge accumulated dust and mud) prior to leaving the site.

The content of the letter appears acceptable having regard to what was discussed at the meeting, although I wish to seek confirmation from Kevin before providing formal confirmation by letter that we can scope out what is listed.

I recall you said you would confirm the weight of the AILs and the number of loads? If we can get this confirmed asap we can scope out depending on the movements.

We would also request site and scale details of the Nantyci compound at your earliest convenience so that any issues can be ironed out before the application is submitted.

I am on leave next week so a formal letter won’t be forthcoming until I return on 3 rd Nov, however, you may use this e-mail and any subsequent confirmation from Kevin beforehand as comfort. Kevin are you ok with this approach?

Unscheduled interviews with users of public rights of way to understand their use of the area. The assessment methodology proposes to consider the spatial scope (defined study area), and temporal scope (development phases) and translation in terms of temporary or permanent impacts. Receptor sensitivity is proposed to be allocated based on a number of key questions considering the scarcity of the affected resources, the capacity of the receptors to accommodate the impact, the users, and the number of people likely to be affected. Magnitude of impact is proposed to be allocated based on a number

Appendix 17.1: Socio-economic Supporting Information – Volume 3

of key questions considering how an impact will affect the existing functioning of a resource, capacity of the resource to adapt, length of impact, and frequency of impact. Significance ranking is assigned based on allocation of receptor sensitivity and magnitude for each potential impact. The Scoping Opinion highlights the need to assess and relay any predicted adverse impact on tourism during construction and operational phases.
