1 INTRODUCTION

1.1 Introduction

1.1.1 This planning application has been submitted by Dial-A-Bin (The Applicant) and seeks planning permission for the installation and operation of a small scale biomass boiler and associated drying unit, utilising collected waste wood as a fuel source to dry animal bedding products at Blackpitts Barn, Helmdon.

1.1.2 The installation of the boiler and use of the associated mobile drying unit will require the reorientation of the maintenance building, as permitted by planning permission 14-00098-WASFUL, to enable the most efficient use of the yard. A small increase in the height of the building is also required to allow sufficient clearance for plant and machinery.

1.1.3 The boiler will stand on the yard consented by planning permission 14-00098-WASFUL.

1.1.4 The planning application is supported by the following documents: GPP-DAB-H-14-01 Site Location Plan GPP-DAB-HB-16-02 Site Plan v2 GPP-DAB-HB-16-03 Site Layout Plan v2 GPP-DAB-HB-16-04 Elevations - Boiler and Drier GPP-DAB-HB-16-05 Elevations - Storage Maintenance Building GPP-DAB-HB-16-06 Photograph Panels A GPP-DAB-HB-16-07 Photograph Panels B D0B-01a Landscaping Plan Planning Form D011-02 Planning Statement 160824

1.2 Blackpitts Barn and Its Surrounding Context

1.2.1 Blackpitts Barn is located over 1km away from the nearest village of Helmdon, and as such there are only a few sensitive receptors in the immediate area. The closest of these receptors is Redlands House at 320m to the North. This property is occupied by the owner of the Farm.

1.2.2 Beyond this the other receptors are as follows: Glasshouses Gwebi Ashvale – 500m North West Glebe Farm – 525m North East Fatlands Farm – 670m North Falcutt Hall – 1100m South East Manor Farm – 1100m North East Falcut Village – 1250 North East Helmdon Village – 1700m North East Site Access and Highway Network

1.2.3 The access into Blackpitts Barn is from the B4525. The B4525 east from the site joins the A43 at a grade separated junction near Syresham, 2 miles north of Brackley. From the farm access to the A43 is a distance of 3 miles. The A43 has been improved to dual-carriageway standard from the M40 (Junction 12) to the M1 (15a) and on into Northampton.



1.2.4 To the west the B4525 joins the A422 just east of the M40 (Junction 11) and at Banbury, a

distance of 7 miles. Public Rights of Way

1.2.5 The nearest public right of way is footpath AP20 which is located to the east of the Application Site and along the eastern boundary of the adjacent field. The footpath runs south towards the village of Halse.

1.2.6 Beyond this the most proximate footpaths are the AX6 which runs from the Radstone Road, to the north of Radstone, in a westerly direction towards Halse Copse. The footpath is approximately 1.1Km to the south of the Application Site.

1.2.7 A bridleway, reference AX18, is located approximately 1.4km to the south of the Application Site. The bridleway connects the village of Radstone to Greatworth to the west. Surrounding Landform

1.2.8 Blackpitts Barn lies in generally undulating countryside and, in particular, on a south facing slope. The countryside is typified by large fields with boundary hedgerows, with scattered trees and copses. The landform provides a degree of natural screening from several aspects. Land Use

1.2.9 A number of waste management uses are operational at Blackpitts Barn. They comprise the following uses: Green waste composting operations; Dry recyclables and inert waste management operations; Mixed waste acceptance and sorting activities; and Anaerobic Digestion Plant currently processing energy crops but with consent to accept and

process food waste.

1.2.10 The surrounding land is in agricultural use and owned by B.F. Humphrey and Sons.

Ecological Designations

1.2.11 The closest site of ecological interest is the Helmdon Disused Railway. This site has been designated as a Site of Special Scientific Interest (SSSI) and is located 300m east of the Application Site. It is designated for its Jurassic limestone grassland habitat.

1.2.12 There are two sites of ecological interest to the west of the Application Site; these are Biodiversity Action Plan Priority Habitats of wet woodland. They appear on OS maps as two parts of Halse Copse, which lie 1km west of the proposed development and 800m southwest.

1.3 The Application Site

1.3.1 The Application Site is located within Dial-A-Bin Ltd.’s waste management and storage yard which is situated in the eastern section of the wider Blackpitts Barn complex, as described above.



1.3.2 The Application Site is 572m2 in area and is located in the north-west corner of the yard. The northern boundary of the Application Site sits adjacent to a mature hedgerow standing at circa 4m in height. A mature oak tree stands to the north of the Application Site and within the hedgerow.

1.3.3 The yard, consented in 2015 and conditions discharged in 2016, is due to commence construction in the near future.

1.3.4 The western side of the Application Site is bounded by a silage clamp associated with the Blackpitts Barn Anaerobic Digestion Plant. The southern and eastern sides of the Application Site are bounded by the remainder of Dial-A-Bin Ltd’s waste management and storage yard.

1.3.5 The yard is well screened by perimeter bunds at circa 2m high on the southern and eastern boundaries. The bunds have been planted up in line with a consented landscape masterplan that is in place across the whole Blackpitts Barn site.

1.3.6 Access to the Application Site will be gained from the east through the yard.

2 THE DEVELOPMENT

2.1 Description of Development

2.1.1 The description of development is as follows:

‘Installation of a small scale biomass boiler, associated mobile drying unit, exhaust stack, increase in height of maintenance building and its reorientation.’

The Biomass Boiler and its Components

2.1.2 The proposal is to install a small scale biomass boiler to generate renewable heat to dry animal bedding products.

2.1.3 The 130Kw biomass boiler and associated dryer are contained within a single steel container unit. The unit comprises a ‘fuel room’, fuel extraction screw, the boiler and heat exchanger. The unit dimensions are 12.9m in length by 2.45m wide by 2.89m high and will be finished in Juniper Green. A cylindrical exhaust flue will stand at a maximum of 5.8m high (above ground level)and connected to the boiler unit.

2.1.4 Another container (drying unit), which holds the materials for drying, sits separately from the boiler unit. This unit is mobile and is a modified ‘Roll on Off’ container. It connects to the boiler unit via a removable flexi pipe, which transfers the renewable heat. The drying unit will have a capacity of circa 40m3 and will have the following dimensions, 9.1m in length by 2.4m wide by 2m high.

2.1.5 The elevations of the various items of kit are shown on drawings GPP-DAB-HB-16-04 Elevations - Boiler and Drier and GPP-DAB-HB-16-05 Elevations – Storage Maintenance Building Rev 1. The units are further detailed by drawing GPP-DAB-HB-16-06 Photograph Panel. The Process

2.1.6 Collected waste wood will be chipped on an as necessary basis to provide a consistently sized fuel for use by the biomass boiler. The chipping takes place on the wider yard. There is sufficient waste wood at Blackpitts Barn, derived from Dial-A-Bin’s current waste management activities. The operations require 500 tonnes of waste wood fuel per annum.

2.1.7 After processing, the fuel is loaded into the fuel room of the Biomass Boiler. Consistent fuel delivery is ensured by a fuel extraction screw, a type of auger, which feeds the chipped wood from the fuel room into the boiler chamber. The fuel is combusted in the chamber and under influence of primary and secondary air, which is air fed from below and above respectively.

2.1.8 The heat generated in the boiler chamber is directed to the heat exchanger where it is transferred to the drying unit by a flexi pipe.

2.1.9 The material within the drying unit that is to be dried is brought to the site already processed. The material is loaded into the unit at the processing site and transported on a hook loading HGV. The material remains within the covered container until dry and then taken off site to market. A ‘wet’ load is then loaded into the drying unit and then back loaded to the site. The cyclical process ensures that there is a consistent requirement for renewable heat.



2.1.10 Dial-A-Bin Ltd has a business agreement with a local producer of animal bedding. The

development will therefore serve local businesses with a renewable and efficient heat source.

2.1.11 If required, the boiler can be used for drying agricultural products such as crops etc, and can be put to good use supporting the surrounding farm activities. Site Layout Arrangements

2.1.12 To accommodate the boiler and drying unit, it will be necessary to reorient the maintenance building that was consented by permission 14/00098/WASFUL. The building will be turned anticlockwise through 90º. The boiler, which is static, will sit to the west of the reoriented building away from the main yard circulation and area of activity. The exhaust stack will sit alongside the boiler unit.

2.1.13 As regular access is required to the drying unit, it will be located to the south of the boiler and maintenance unit, making an ‘L-shape’ with the boiler.

2.1.14 The site layout is shown by drawing GPP-DAB-HB-16-03 Site Layout Plan v2.

2.1.15 To accommodate the changes in the arrangement and to allow for access to the maintenance building, it will be redesigned so that two main access points are located along the eastern elevation with a personnel access on the southern boundary. The arrangements are shown on drawing GPP-DAB-HB-16-05 Elevations - Storage Maintenance Building. It is also proposed to increase the height of the building by 1m in order to provide sufficient clearance for plant and machinery which is also reflected on the elevations. Other Arrangements

2.1.16 Operations associated with the loading of shredded fuel material, loading of fuel material into the feed hopper, and the delivery and removal of the drying unit will be confined to the normal operating hours of the site. The permitted operational hours are: 06:30 to 18:00 Monday to Friday 06:30 to 12:00 Saturday No working on Sundays and Bank Holidays

2.1.17 The boiler and dryer will operate for 24 hours per day.

2.1.18 To ensure that the development does not have an adverse impact upon the existing hedgerow

and trees, appropriate standoffs have been incorporated into the scheme design. These are 8.5m from the boiler to the existing Oak and a general 5m standoff from the hedgerow, as shown on GPP-DAB-HB-16-03 site layout plan v2.



3 PLANNING POLICY

3.1 Introduction

3.1.1 This chapter provides an indication of the main Development Plan policies and national planning guidance that has been considered and assessed in the preparation of this planning application.

3.1.2 The Development Plan in this instance consists of: Northamptonshire Minerals and Waste Local Plan (October 2014)

3.1.3 The main objectives and planning policies that are relevant to the proposal are set out below.

3.2 The Development Plan

Northamptonshire County Council’s Mineral and Waste Local Plan

3.2.1 Policy 11 of the plan identifies the capacity waste management capacity requirement that is to be provided across the County for the plan period. The policy also identifies that the:

‘provision will come from a mix of extensions to existing sites, intensification or re-development of existing sites and new sites, providing they all meet the spatial strategy for waste management and are assessed as meeting environmental, amenity and other requirements.’

3.2.2 Policy 12 sets out NCC’s spatial strategy for waste management. It provides that:

Northamptonshire’s waste management network, particularly advanced treatment facilities with a sub-regional or wider catchment, will be focused within the central spine and the sub-regional centre of Daventry. Development should be concentrated in Northampton, Wellingborough, Kettering, Corby and Daventry. Development in the smaller towns should be consistent with their local service role.

Facilities in urban areas should be co-located together and with complementary activities.

3.2.3 Policy 13 provides development criteria for waste management facilities which are not

allocated: Proposals for waste management facilities on non-allocated sites (including extensions to existing sites and extension to allocated sites) must demonstrate that the development: Does not conflict with the spatial strategy for waste management; Promotes the development of a sustainable waste network and facilitates delivery of Northamptonshire’s waste management capacity requirements; Clearly establishes a need for the facility identifying the intended functional role, intended catchment area for the waste to be managed, market base for any outputs, and where applicable the requirement for a specialist facility; Is in general conformity with the principles of sustainability (particularly regarding the intended catchment area); Facilitates the efficient collection and recovery of waste materials; and Where intended for use by the local community, is readily and safely accessible to those it is intended to serve.



3.2.4 Policy 22 is concerned with addressing the impact of proposed minerals and waste

development: Proposals for minerals and waste development must demonstrate that the following matters have been considered and addressed: Protecting Northamptonshire’s natural resources and key environmental designations

(including heritage assets); Avoiding and / or minimising potentially adverse impacts to an acceptable level,

specifically addressing air emissions (including dust), odour, bioaerosols, noise and vibration, slope stability, vermin and pests, birdstrike, litter, land use conflict and cumulative impact;

Impacts on flood risk as well as the flow and quantity of surface and groundwater; Ensuring built development is of a design and layout that has regard to its visual

appearance in the context of the defining characteristics of the local area; Ensuring access is sustainable, safe and environmentally acceptable, and Ensuring that local amenity is protected.

3.2.5 Policy 23 relates to encouraging sustainable transport and provides that minerals and waste related development should seek to minimise transport movements and maximise the use of sustainable or alternative transport modes. Where possible, minerals and waste related development should be located, designed and operated to enable transport by rail, water, pipeline or conveyor. It states that minerals and waste related development should be well placed to serve their intended markets or catchment area(s) in order to reduce transport distances and movements in order to support the development of sustainable communities that take responsibility for the waste that they produce and work towards self-sufficiency. Proposals for new development or development that would result in a significant increase in transport movements should include a sustainable transport statement to demonstrate how the above has been taken into consideration.

3.2.6 Policy 24 is concerned with natural assets and resources. It states that: Minerals and waste development should seek to achieve a net gain in natural assets and resources, through: protecting and enhancing international and national designated sites, delivery of wider environmental benefits in the vicinity where development would adversely

affect locally designated sites or other features of local interest, protecting and enhancing green infrastructure and strategic biodiversity networks, in

particular the River Nene and other sub-regional corridors, and contributing towards Northamptonshire Biodiversity Action Plan targets for habitats and

species. Proposals for minerals and waste development will be required to undertake an assessment (where appropriate) in order to: identify and determine the nature, extent and level of importance of the natural

assets and resources, as well as any potential impacts, and identify mitigation measures and / or requirement for compensation (where

necessary) to avoid, reduce and manage potentially adverse impacts.

3.2.7 Policy 25 is concerned with Landscape Character. It provides that: Minerals and waste development should seek to reflect Northamptonshire’s landscape character. Development should mitigate potentially adverse impacts on the local character and distinctiveness of Northamptonshire’s landscape where



necessary during the development, operational life, restoration, aftercare and after-use. Opportunities for enhancement should be maximised through restoration, aftercare and after-use. Proposals for minerals and waste development will be required to undertake a landscape impact assessment (where appropriate) based on the landscape character assessment in order to identify:

the presence of landscape values (including their nature, extent and level of importance) and determine any potential impacts,

any necessary measures to mitigate potentially adverse impacts, and opportunities to protect and enhance particular features that create a specific

aspect of local distinctiveness or character. 3.2.8 Policy 27 provides guidance on layout and design quality:

The layout and overall appearance of waste management facilities, and where appropriate minerals development, will be required to demonstrate that the development:

Supports local identity and relates well to neighbouring sites and buildings; Is set in the context of the area in which it is to be sited in a manner that

enhances the overall townscape, landscape or streetscape (as appropriate); Utilises local building materials as appropriate; Incorporates specific elements of visual interest; and Builds-in safety and security.

National Planning Policy for Waste (October 2014)

3.2.9 Paragraph 1 of the NPPW states that ‘Positive planning plays a pivotal role in delivering this country’s waste ambitions through:

Delivery of sustainable development and resource efficiency, including provision of modern infrastructure, local employment opportunities and wider climate change benefits, by driving waste management up the waste hierarchy…

3.2.10 Paragraph 5 provides guidance on suitable sites and areas: Waste planning authorities should assess the suitability of sites and/or areas for new or

enhanced waste management facilities against each of the following criteria: The extent to which the site or area will support the other policies set out in this document; Physical and environmental constraints on development, including existing and proposed

neighbouring land uses, and having regard to the factors in Appendix B to the appropriate level of detail needed to prepare the Local Plan;

3.2.11 Paragraph 7 is concerned with determining planning applications. It provides that: When determining waste planning applications, waste planning authorities should: Consider the likely impact on the local environment and on amenity against the criteria set

out in Appendix B and the locational implications of any advice on health from the relevant health bodies.

Ensure that waste management facilities in themselves are well-designed, so that they contribute positively to the character and quality of the area in which they are located.



National Planning Practice Guidance (2014)

3.2.12 Planning Practice Guidance provides advice on determining waste related planning applications. In particular it advises on when unallocated sites can be used and recognises that there may be changes that give rise to opportunities not envisaged in the Local Plan. In the case of waste facilities, the onus is on applicants to demonstrate that the facility will not undermine the waste planning strategy through prejudicing the movement of waste up the hierarchy. Waste Management Plan for England December2013

3.2.13 The Government’s latest thinking on waste management was published in December 2013 in the Waste Management Plan for England. It sets out how it will support the implementation of the objectives and provisions of the revised Waste Framework Directive. It continues to promote compliance with the waste hierarchy.

3.2.14 The document states: The Government supports efficient energy recovery from residual waste – of materials which cannot be reused or recycled - to deliver environmental benefits, reduce carbon impact and provide economic opportunities. Our aim is to get the most energy out of waste, not to get the most waste into energy recovery.

National Planning Policy Framework, March 2012

3.2.15 The National Planning Policy Framework was published on the 27th March 2012 and came into force immediately with respect to plan and decision making. The NPPF states at paragraph 5 of its introduction that it does not contain specific waste policies 'since national waste planning policy will be published alongside the National Waste Management Plan for England'. However, paragraph 5 goes on to say that local authorities should have regard to the policies in the National Planning Policy Framework in preparing their waste plans.

3.2.16 The NPPF provides a presumption given in favour of development with sustainable credentials. Paragraph 14 of the NPPF states:

At the heart of the planning system is a presumption in favour of sustainable development, which should be seen as a golden thread running through both plan making and decision taking. For decision-taking this means

Approving development proposals that accord with the development plan without delay and

Where the development plan is absent, silent or relevant policies are out of date, granting planning permission unless:



o Any adverse impact of doing so would significantly and demonstrably outweigh the benefits, when assessed against the policies in this Framework taken as a whole or

o Specific policies in this Framework indicate development should be restricted.



4 ASSESSMENT OF THE PROPOSED DEVELOPMENT

4.1 Introduction

4.1.1 The starting point for the assessment of this proposal is the Development Plan. From an assessment of the pertinent Development Plan policies and other planning considerations the ‘main’ issues in the determination of this planning application are considered to be: Compliance with Northamptonshire’s waste spatial strategy and Sustainability Criteria Environmental and Amenity Considerations (including Landscape Character and Visual

Amenity, Noise, Air Quality and Dust, Ecology and Biodiversity and Drainage) Layout and Design Quality Transport and Highway Capacity

4.2 Compliance with Northamptonshire’s Waste Spatial Strategy and

Sustainability Criteria

4.2.1 Policy 12 of Northamptonshire’s Mineral and Waste Local Plan identifies the locations that are considered acceptable when considering the merits of locating specific types of waste management development. The policy directs development to the central spine, sub regional centre of Daventry and rural service centres.

4.2.2 The proposed development directly relates to an existing waste management operation. The direct relationship is twofold, in that it is located at a waste management yard at Blackpitts Barn and it will source its fuel from the wood waste that already passes through Blackpitts Barn in association with existing Dial-A-Bin waste management activities.

4.2.3 The acceptability of the yard and the Application Site, in terms of compliance with the spatial strategy, has been considered as recently as 2015 during the determination of planning application 14/00098/WASFUL for the yard. The officer’s delegated report at paragraph 6.3 stated:

‘Policy 12 sets out the spatial strategy for the county’s waste management network concentrating the majority of facilities within the central spine, i.e. the main urban areas of the county extending from Northampton in the west to Corby in the north-east, and encompassing Wellingborough. Although this proposal does not sit within the central spine, it relates to an existing waste management operation and is linked with existing employment uses at the Blackpitts Farm site. The establishment of the yard will allow the applicant to improve the recovery rates of recyclable waste streams. It should also be noted that the application site has extant planning permission for the storage and processing of waste wood (SN/03/0544). These circumstances carry significant weight in support of the current application.’

4.2.4 Planning permission 14/00098/WASFUL has now been granted further strengthening the

principle of waste management at the Application Site.

4.2.5 Policy 11: Northamptonshire’s Waste Management Capacity, identifies that where new waste management development proposals comes forward there is an expectation that some will be



located at existing waste management sites. On the basis of the above and its location at an active waste management site, the proposed development is situated at an appropriately located site. These are material considerations that weigh heavily in the favour of the development.

4.2.6 In support of the strategy set by Policy 12, Policy 13 sets out the main criteria that should be assessed in determining the acceptability of the location of waste development. Specifically the policy requires that development:

Does not conflict with the spatial strategy for waste management; Promotes the development of a sustainable waste network and facilitates

delivery of Northamptonshire’s waste management capacity requirements; Cearly establishes a need for the facility identifying the intended functional

role, intended catchment area for the waste to be managed, market base for any outputs, and where applicable the requirement for a specialist facility;

Is in general conformity with the principles of sustainability (particularly regarding the intended catchment area); and

Facilitates the efficient collection and recovery of waste materials.

4.2.7 It has been shown that the location of the development in the context of the waste spatial strategy is acceptable. The co-location of the development with the existing operations promotes the development of a sustainable waste network as it will enable operational efficiencies to be gained. Furthermore, the utilisation of waste from already collected waste streams at the site will support the waste management capacity requirements identified by Policy 11.

4.2.8 The development will enable a proportion of the collected waste stream that is collected by the associated Dial-A-Bin Ltd waste management activities to be utilised on site for a beneficial purpose. The National Planning Policy for Waste identifies that waste management activities should strive to move waste up the hierarchy from disposal to prevention. The heat recovered from the biomass process will be beneficially used in supporting a local business that requires a heating source to dry their animal bedding material. The proposed development will support existing recycling operations at the site through utilising the recycled waste wood for the recovery of renewable heat and energy. The development therefore facilitates the efficient collection and recovery of waste materials.

4.2.9 The development therefore complies with the criteria set out in Policy 13 and the requirements of the waste hierarchy.

4.3 Environmental and Amenity Considerations

4.3.1 Policy 22 is the key policy that guides development so that environmental and amenity impacts are avoided, minimised or mitigated. The key criteria in the context of the proposed development are considered and addressed below: Landscape and Visual Amenity

4.3.2 In addition to the requirements of Policy 22, which requires that development must have‘regard to its visual appearance in the context of the defining characteristics of the local area’, Policy 25 deals with Landscape Character. The Policy requires that:



‘….development should mitigate potentially adverse impacts on the local character and distinctiveness of Northamptonshire’s landscape where necessary during the development, operational life….’

Visual Amenity

4.3.3 The Application Site sits within the wider Blackpitts Barn complex as shown by drawing GPP-DAB-HB-16-02 Site Plan v2 and will be located on a relatively small parcel of land in the north western corner of the existing yard. The Application site is bounded on its northern side by a mature hedgerow which stands at 4m high. Immediately to the north of the Applications Site and within the mature hedgerow stands a mature Oak tree at approximately 9m tall. The hedgerow and tree is shown on drawing GPP/DAB/HB/16/07 Photograph Panel B.

4.3.4 The yard that the development is to be located within is bounded on its eastern and southern side by an existing earth bund which stands at approximately 2 to 2.5m tall. A planting scheme shown by drawing DOB-01a Landscape Scheme, consented in line with permission 14/00098/WASFUL for the storage and waste management yard, is to be implemented during the next planting season. The scheme provides a substantial tree belt along the eastern and southern boundaries of the yard and will provide substantial screening once mature.

4.3.5 The development includes the permanent installation of a containerised unit along with a ‘Roll-on-off’ type unit, which is by its nature a mobile unit. These units are a maximum of 3m in height. The biomass boiler also requires an exhaust stack, standing at 5.8m tall from ground level, to be installed. Furthermore, in reorienting the building it is also proposed to increase the height of the building by 1m to 6m at the ridge to provide sufficient clearance for plant and machinery.

4.3.6 The height of the mature hedgerow, the location next to the reoriented maintenance building, the existence of the perimeter bund around the yard and the consented planting scheme will mean that the containerised unit and mobile drying unit will be screened from view. It is therefore the stack and the increased building height that will be the most sensitive elements of the development in visual terms.

4.3.7 Form the north and west the Application Site will be screened by existing vegetation and intervening structures on the Blackpitts Barn site and will therefore not be adverse affected by the development. The most sensitive views will therefore be from the public rights of way to the east along footpath AP20 and long distance views from footpath AX6 and bridleway AX18 to the south of the site towards the village of Radstone.

4.3.8 The view of the site from footpath AP20 is shown on drawing GPP/DAB/HB/16/07 Photograph Panel B. The perimeter bund is identifiable and will screen a significant amount of the development, particularly once the planting has matured. It is the building that has the greatest potential to be seen in these views as the exhaust stack will sit behind the building out of sight. The building will sit at the far end of the site away from the eastern perimeter bund. As consented by planning application 14/00098/WASFUL, the finished land levels fall from north east to south west across the consented yard. It is not proposed to alter the consented finished topographical levels. The building will sit at a lower ground level that that of the existing bund, a difference of circa 0.5m, thus providing some further screening benefits when the site is viewed from footpath AP20. Footpath AP20 sits at a similar topographical level to that of the bottom of the bund and therefore views for the site will generally be directed over the bund, skywards.



4.3.9 Views from public rights of way AX8 and AX18 will be long distance views. They are shown on drawing GPP/DAB/HB/16/07 Photograph Panel B. The development proposed development will not have a significant alter the view of the current view of the site as shown on the drawing. The mass of the building will also be reduced due to its reorientation. The scale of the proposed development is not of a sufficient size to be distinguishable in views from the identified locations.

4.3.10 Furthermore the principle and potential impacts of the maintenance building (at a maximum height of 5m) has already bene considered by planning application 14/00098/WASFUL. The officer’s report (attached at Appendix 1) for that applications states at paragraph 6.11:

‘The building will be situated along the mature hedgerow on the northern boundary which is approximately 3 to 4m high. Given that the yard surface is to be re-graded, only the top 1 to 1.5m of the building is likely to be visible above the existing mature hedge. The nature and small scale of the proposed building would not have a significant landscape impact in the context of all existing and planned buildings at Blackpitts Barn Farm and would therefore have a minor affect on the visual impact of the site.’

4.3.11 The development will therefore not have an adverse impact in visual amenity terms as it is not substantially different to the type and scale of development permitted by planning permission 14/00098/WASFUL. Landscape Character

4.3.12 The proposed development is of a relatively small scale in comparison to the development across the wider Blackpitts Barn site. The development is of a type that fits with the adjacent development at Blackpitts Barn and thus the character of the land use at Blackpitts Barn.

4.3.13 The small scale nature of the development means that it will not materially change the nature of the Application Site, the yard or the wider Blackpitts Barn site within the landscape character area. The officer’s report written in conjunction with the determination of planning application 14/00098/WASFUL identified the following in relation to the construction of the yard and maintenance building:

‘The landscape and visual amenity impacts of the proposals are considered acceptable having regard to Policies 24 and 25 of the NMWLP (2014).’

4.3.14 The development is also considered acceptable having regard to policies 24 and 25 of the NMWLP. Air Quality and Dust

Air Quality

4.3.15 The proposed development is a small scale biomass boiler of circa 130kw energy output. The boiler will accept grades A, B and C waste wood as a fuel source. However the fuel input is relatively small, equating to 500 tonnes of wood waste per annum.

4.3.16 The boiler has been certified as meeting ‘the air quality requirements of the non-domestic Renewable Heat Incentive (RHI) – Reg 5A(3) and Schedule A1’. Certification is provided at Appendix 2.



4.3.17 The development will therefore not have an adverse impact on air quality.

Dust

4.3.18 There is some potential for dust generation in preparing the wood waste for use through shredding. It is however only proposed to use a small mobile shredder/chipper which will be on site solely for the purpose of preparing wood material for fuel use. The shredding will be carried out on the wider yard. Due to the small tonnages required to fuel the boiler, the shredding operation will not be an intensive activity. It will be carried out on the yard, where there will be water available for dust suppression purposes if necessary.

4.3.19 Therefore there will not be an adverse impact in dust emission terms. Noise

4.3.20 The development is for a small scale biomass boiler. The greatest noise potential is associated with the shredding of waste wood during the fuel preparation process. The normal working hours of the site are: 06:30 to 18:00 Monday to Friday 06:30 to 12:00 Saturday

4.3.21 However as a mitigation measure shredding will not be carried out before 07:30 hours on week

days and 08:00 hours on a Saturday.

4.3.22 The noise associated with the shredding are consistent with the type of the operations carried out at across Blackpitts Barn, particularly those associated with the composting operations. As the proposed shredder is of a significantly smaller scale than the mechanical shredder used by the composting operations it is likely to have a significantly lower noise output. Furthermore, the shredding operations will only be periodic as only wood to be used as a fuel source will be shredded.

4.3.23 The boiler will produce some low level noise emissions. The boiler however will be contained with an acoustic housing and will benefit from the screening offered by its location next to the maintenance unit and the silage clamps. There are a number of intervening buildings and areas of dense vegetation between the Application Site and the nearest sensitive residential receptors which will reduce the potential for adverse noise impacts.

4.3.24 The nearest residential receptor is Redlands House, located to the north of the Application Site along the main access track into Blackpitts Barn. The occupier of Redlands House has a vested interest in the operations undertaken at the Blackpitts Barn site, as the landowner of the farm.

4.3.25 It is not considered that the development will generate adverse noise impacts. Ecology and Biodiversity

4.3.26 The development will not have an adverse ecological or biodiversity impact as it will be located at an already constructed yard. The yard has recently been constructed following the detail of an agreed Construction Environmental Management Plan, as required by planning permission 14/00098/WASFUL.



4.3.27 The proposed development scheme has been designed to ensure that sufficient stand off from the northern hedge boundary and mature trees have been incorporated, thus accounting for the root protection area. The stand-off areas are shown on drawing GPP-DAB-HB-16-03 Site Layout Plan v2.

4.3.28 The principles agreed for tree protection through the discharge of condition 13 of planning permission 14/00098/WASFUL will be adopted in the construction of the proposed development. These are mainly ensuring that the following strand-offs are maintained: Stand off from Pedunculated Oak – 8.5m Stand off from hedgerow – 5m

4.3.29 The above distances have been calculated in line with guidance set out in BS 5837: 2012.

Drainage

4.3.30 The existing drainage infrastructure will be retained. The scheme comprises the: Perimeter drainage ditches to collect site surface water The limitation of discharge rates to lower than pre-development conditions Surface water diverted to the existing (remodelled) balancing pond which is of sufficient

capacity to incorporate a 100 year storm plus a 20% allowance for climate change based on the FEH data.

Inclusion of a bypass interceptor to protect the receiving watercourse from contamination

4.3.31 The detailed drainage scheme was agreed through the discharge of condition 22 of planning permission 14/00098/WASFUL (13th April 2016) and is therefore compliant with the most recent guidance. The agreed drainage scheme is attached at Appendix 3.

4.3.32 There will be no adverse impact in drainage terms generated by the scheme.

4.4 Layout and Design Quality

4.4.1 Policy 27 of the Northamptonshire’s Mineral and Waste Local Plan identifies the need for considerate design to be incorporated into new development proposals. In the case of this application it is the following tests of Policy 27 that are relevant:

‘The layout and overall appearance of waste management facilities, ….., will be required to demonstrate that the development:

supports local identity and relates well to neighbouring sites and buildings, is set in the context of the area in which it is to be sited in a manner that

enhances the overall townscape, landscape or streetscape (as appropriate), …….. builds-in safety and security.

4.4.2 The additional elements of the new development; the boiler unit, dryer unit and stack are

consistent in relation to the type and nature of existing waste management development in the surrounding Blackpitts Barn site. The site layout has been arranged so that the units benefit from the existing screening offered by mature hedgerows, and the proposed maintenance building, the principle of which has already been consented and the landscaping proposals



agreed as appropriate. The proposed development does not detract from the overall landscape context due to these arrangements.

4.4.3 The location of the proposed development to the west and south of the maintenance building provides sufficient separation between the proposed use and the main waste management and storage activities that are to be carried out on the wider yard. A barrier will be located between the personnel entrance at the southern elevation of the maintenance building and the proposed location of the drying unit to ensure safe operations in that area.

4.4.4 Sufficient standoffs have been incorporated between the boiler unit and the perimeter fence to be constructed on the western boundary, adjacent to the silage clamps. The fence is permitted by permission 14/00098/WASFUL.

4.4.5 The development complies with the requirements of Policy 27.

4.5 Sustainable Transport and Highway Capacity

4.5.1 Policy 23 encourages development to adopt sustainable transport principles. The fundamental principle is to minimise transport movements as much as possible. The development will utilise incoming wood waste materials as a fuel source. The wood waste is collected in relation to Dial-A-Bin Ltd’s bin and skips service. The material is currently sorted and bulked up at the Blackpitts Barn site and then transported to an alternative site for further use or processing.

4.5.2 The diversion of a proportion of the wood waste (circa 500 tonnes) for use as fuel on site in the biomass boiler will reduce the amount of bulked loads of wood waste leaving Blackpitts Barn. Thus reducing the amount of HGV movements generated by Dial-A-Bin Ltd’s waste management activities at Blackpitts Barn. The bulked loads are on average 10 tonne loads and on average generate 1 load (2 movements) per week. It is only proposed to operate a single drying unit in connection with the Biomass Boiler. The unit will circulate between the Application Site and the site where the Animal bedding is to be prepared (away from Blackpitts Barn). The process will be to unload dried material at the preparation site and then to backhaul a load of ‘wet’ material for drying. The drying process takes in the region of two to three days to complete. The development will therefore generate in the region of 6 additional movements to and from the site each week.

4.5.3 The proposed development will therefore generate a small amount of additional HGV movements to and from the Blackpits Barn site. The increase however will be negligible in the context of the total HGV movements generated by waste management operations at Blackpitts Barn.

4.5.4 The development will not have an adverse impact in Sustainable Transport and Highway Capacity terms.



5 CONCLUSION

5.1 The Planning Balance

5.1.1 The development proposed incorporates the installation of a small scale biomass boiler and drying unit at an existing waste management site, Blackpits Barn, Helmdon. The development will require the reorientation of the permitted maintenance building. It is proposed to increase the building by 1m to provide sufficient clearance for plant and machinery.

5.1.2 In strategic spatial policy terms, whilst the development is not in strict compliance with policy 12 of the Minerals and Waste Local Plan, the development is located at an existing waste management complex which has a number of extant planning permissions in place. The Application Site is located at a site (within the wider complex) that has a detailed waste planning history, the most recently determined planning permission (14/00098/WASFUL) granted as recently as April 2015.

5.1.3 Policy 11 of the Minerals and Waste Local Plan directs new waste management proposals to existing waste management sites. Furthermore, whilst only being a relatively small scale development it will contribute to the waste management capacity requirements identified by the same policy.

5.1.4 The development complies with Policy 13 through co-location with other waste management operations, generating efficiencies between co-located waste development and driving waste up the hierarchy.

5.1.5 This application is also compliant with Policy 22 of the Minerals and Waste Local Plan which deals with environmental and amenity matters. The small scale nature of the development and the surrounding context means that the development will not have an adverse impact in environmental and amenity terms.

5.1.6 The development, in landscape character terms, will not be materially different from the principles established by planning permission 14/00098/WASFUL. Furthermore, the development has been designed so that it utilises the benefits of screening from existing mature hedgerows, buildings and committed landscape planting scheme. The development therefore complies with both requirements of Policy 23 and 27 of the Minerals and Waste Local Plan.

5.1.7 The operations will have an imperceptible impact in terms of the HGV movements to be generated and will therefore not have a significant adverse impact in sustainable transport, highway capacity or access safety terms.

5.1.8 The proposed development does not to conflict with the waste spatial strategy due to its links with an existing waste management site. There is substantial co-location, waste management efficiency and waste recovery benefits that weigh heavily in favour of the development. Furthermore, the development complies with the environmental, amenity, design and sustainable transport requirements of the Mineral and Waste Local Plan.

5.1.9 There are no other material considerations that would warrant a refusal of planning permission.

1.0 Introduction 1.1 Abington Consulting Engineers have been appointed to produce a surface water drainage report in support of an application to discharge a planning condition for a waste management operation at Blackpits Farm, Helmdon in Northamptonshire. 1.2 The site is located on a permitted wood storage area which is rough ground with limited vegetation. It has an area of approximately 0.4 hectares and slopes towards the south west. 1.3 It is proposed that approximately half of the yard will be concreted where waste is handled and stored. The remainder will be constructed in hardcore and used for skip and bin storage. Eventually it is anticipated that the whole of the yard will be concreted at some time in the future. 2.0 Existing Surface Water Drainage 2.1 There is no formal drainage to the existing site. 2.2 The British Geological Survey mapping shows the site is set on a mudstone bedrock with superficial deposits described as Oadby Member – Diamicton (refer to mapping in Appendix 1). This can be lenses of sand and gravel or clay and silt. 2.3 The nearest watercourse is approximately 0.6km to the south of the site. 2.4 Calculations set out in Appendix 2 show that the green-field run-off rate of 1.5 l/s might be expected for a 1 year return period. 3.0 Surface Water Disposal Options 3.1 Table 1 below is an extract from ‘SUDS a Practical Guide’ published by the Environment Agency Thames Region (2006). The most suitable surface water disposal technique should be selected from this table based on the limitations of the site.

Table 1 - SUDS Hierarchy 3.2 Based on the geological mapping, the ground may be sufficiently permeable to allow infiltration.


3.3 The nearest watercourse is 0.6km to the south of the site and the land between is in the control of the Applicant. Therefore, it is possible to drain the development to the watercourse. 3.4 The existing Anaerobic Digestion Plant adjacent to the site already discharges to the watercourse via a balancing pond located to the south of the site. Construction was carried out in 2014 in accordance with the requirements of a Flood Risk Assessment, extracts of which are presented in Appendix 3. No assessment of the permeability of the ground was carried out in the FRA and therefore the design of the balancing pond was based on a limited discharge to the watercourse. There is plenty of room to extend the pond to accommodate the run-off from the proposed development. 4.0 Proposed Surface Water Drainage Scheme 4.1 Ditches will be constructed along the western and southern boundaries of the yard area. These will be drained to the south west corner and the run-off passed through a bypass interceptor to ensure oil is prevented from discharging into the receiving watercourse. 4.2 A swale will be constructed between the bypass interceptor and the existing balancing pond. Run-off from the yard will either soak into the ground or be transported to the balancing pond. The run-off reaching the balancing pond will either be attenuated and discharged at a limited discharge rate into the watercourse, or soak into the ground under the balancing pond. 4.3 As a worst case scenario, it has been assumed that the ground will be found to be impermeable and therefore all of the run-off will reach the balancing pond. Therefore, the pond will need to be large enough to accommodate the additional run-off. No change to the flow control device is proposed and therefore there will be an overall reduction in the rate of run-off from the development. 4.4 Calculations from the original FRA for the balancing pond are presented in Appendix 3. These are based on FSR data which is less onerous than the comparable FEH data for this location. Surface water is attenuated on site for a 100 year return period with a 20% allowance for climate change in accordance with NPPF requirements. The calculations show that the total storage volume requirement of 1612m3 is required for the AD Plant. 4.5 Calculations presented in Appendix 2 show the same model with an additional area of 0.4 hectares added (the yard area). The same discharge rates are retained and the resulting volume requirement is 2416m3 based on FEH data. The drawing presented in Appendix 4 and supporting calculations in Appendix 2 show that the capacity of the existing balancing pond is 2700m3 which is of a sufficient size to accommodate the new development. Ditches, swales and other proposed drainage features are also shown. 4.6 The levels quoted on the original FRA storage model vary from the as built levels shown for the pond. Therefore, before construction of the works, an assessment of the flow control chamber should be carried out to ensure flow controls are set at the appropriate level and that the balancing pond functions as originally designed.


5.0 Conclusions 5.1 Additional run-off will either be discharged into the ground or into the existing balancing pond which is of sufficient size to cope with the new development. The existing drainage system will limit the discharge rate to a lower rate than pre-development conditions. 5.2 The existing balancing pond will be designed and modified to incorporate a 100 year storm plus a 20% allowance for climate change based on the more onerous FEH data. 5.3 Providing a bypass interceptor will protect the receiving watercourse from contamination.

Blackpits Barn Anaerobic Digestion Facility, Helmdon - Flood Risk Assessment July2011

Page 7 of 18

4.3 Site Run-off - The probability of flooding in the downstream catchment due to run-off from the site is an important aspect of this assessment, particularly given the flooding on the receiving watercourses indicated on the SFRA and EA mapping.

A detailed revision of the original site drainage proposals to accommodate the change in site layout has yet to be developed at the time of carrying out this assessment. However the extant planning permission for previous phases of the development was subject to planning conditions requiring detailed design and calculations for an attenuation system to limit off-site storm flows. These were carried out by Infrastructure Design Studio. The design was developed to replicate pre-development run-off rates as agreed with the Environment Agency. We have been assured that the Applicant is committed to providing a revised drainage system that continues to meet the originally agreed run-off rates using an equivalent control mechanism to limit surface water run-off and with adjustment to the storage volume to match the changes in impermeable area. With the drainage proposals fully implemented there will be no increase in flood risk to the downstream catchment for all events up to the 100 year (1% annual probability) storm event.

Section 6 describes in more detail the methodology for addressing run-off reduction.

5 Climate Change

5.1 The design life of the various installations included in the application would be a maximum of 60 years. Planning Policy Statement 25 Annex B suggests that by the period 2055-2085, peak rainfall intensity will have increased and flooding would therefore tend to be more serious than 2011 conditions. Table B.2 of PPS25 suggests that a climate change allowance of 20% should be included in the run-off assessment. Drainage installations described in Section 6 will therefore use rainfall rates factored by 1.2 at detailed design stage to ensure that downstream conditions do not worsen should future climate change

predictions become a reality.

6 Detailed Development Proposals

6.1 The proposed layout of the development is shown in Figure 2. The main differences in the layout compared to the extant planning permission are as follows:

The roofed anaerobic digestion building is replaced with two separate circular units set in a largely gravelled surface with additional paved hardstandings and access tracks

Opposite the anaerobic digestion area will be a silage storage area set into the ground with a retaining wall to the sides and rear and open to the main site access track on its western side

The net effect of the changes in terms of additional impermeable area has been calculated by comparing a like for like site area encompassing the whole anaerobic facility and the silage store. The total increase in impermaeable area is 4624m2. Although on the face of it the introduction of the silage area would increase impermeable area by replacing a previously unsurfaced area of the site, current silage regulations dicate that all run-off will be separately drained and retained on site in order to limit risk of polluting the receiving watercourse. The relevant regulations are the Water Resources (Control of Pollution) (Silage Slurry and Agricultural Fuel Oil) Regulations 2010. These are commonly referred to as SSAFO.

To comply with these regulations the silage area will have perimeter cut off drains and will be sloped away from adjacent surfaces so that any run-off is contained. The collected run-off will then be pumped into the site’s anaerobic treatment system at a controlled rate, using a suitably sized pumping station holding tank buffer the run-off rate against the pump capacity.

Having complied with these regulations, there remains the potential that


Page 8 of 18

the silage area may become disused at some point in the future so using a similar strategy to that agreed for the green waste maturation slab area, the area of silage hardstanding has been included in the potential impermeable area contributing to the attenuation pond.

6.2 Figure 3 shows an overview of the drainage layout pepared for the extant planning application and has been annotated to describe the main principles of the original drainage design.

6.3 The parameters for limiting the site discharge will remain as for the extant planning permission and the proposed discharge rates for the 1, 30 and 100 year return period storm events are summarised in Table 1 below.

100 Year (1%)

Agreed Pre-Development

Discharge Rate

13.957l/s 35l/s 52l/s

Table 1 Pre development run-off rates

6.4 Detailed re-design of the drainage network is beyond the scope of this

assessment and will follow any grant of planning permission, however apart from some minor re-routing of drain runs in the vicinity of the proposed anaerobic treatment facility the only design change required to the original design shown in Figure 3 is adjustment of the storage volume of the attenuation pond. At the time of preparing this assessment the originally consented pond design has been instigated in as far as the bulk excavation has taken place in preparation for profiling to the organic shape shown in the original design. The outfall structure and flow control device (see Figure 4) have yet to be installed as there was a perception that until the final design for the anaerobic digestion system was resolved, building the outfall may result in abortive construction work.

6.5 In order to establish the extent of pond enlargement required we have

re-run the original pond design calculations with an additional area of 4624m2 included in the 0-4 minute portion of the time/area diagram. Appendices A, B and C show the relevant Microdrainage pond calculations for the 1, 30 and 100 year return period storms respectively. The critical storms highlighted in red in the calculations show that the discharge rates are met in each case. The pond size has been scaled up to match the new contributing area and the required pond size at each level increment is shown on Page 4 of each the three sets of calculations. This size of pond can easily be accommodated through adjustments to the the bulk earthworks that have already taken place. The change in hydraulic characteristics has resulted in slight changes to the complex outfall control shown in Figure 4. The two orifices and the overflow weir all stay at the same level but the central orifice has been reduced in size to 110mm dia. and the overflow weir has been widened to 315mm to match the required 100 year outflow rate of 52 l/s. These changes will be indicated on a new version of the outfall drawing in response to a planning approval.

7 Flood Risk Management Measures

7.1 As far as practicable, the site drainage systems have been designed to operate passively without the need for excessive maintenance or intervention. Where appropriate, open ditches have been used instead of piped drains to minimise the risk of blockages caused by siltation. This is especially relevant for this site given the number of HGV movements that have potential to bring mud and rod silt onto the property. The applicant has also committed to provide the following range of maintenance procedures in order to ensure the successful long term performance of the drainage and attenuation systems:

Regular checking and clearing of silt traps.

Regular removal of silt from drainage gullies.

30th November 2016 Nathan Maddox GP Planning Ltd The Stables, Long Lane East Haddon Northampton NN6 8DU Dear Nathan Re: Potential Impact on the Helmdon Disused Railway SSSI of Emissions from

the Proposed Biomass Boiler at Blackpitts Barn Farm, Helmdon

I write in connection with the comments made by Natural England in relation to the potential impact of emissions of oxides of nitrogen (NOX) and sulphur dioxide (SO2) from the proposed biomass boiler installation at Blackpitts Barn Farm, on the integrity of the Helmdon Disused Railway SSSI.

The proposal is to install a 130 kWth biomass boiler to generate renewable heat to dry animal bedding products. Collected waste wood will be chipped on an as-required basis to provide a consistently sized fuel for use by the biomass boiler. The waste wood will be processed to Biomass Supplier List standard, ensuring that the fuel material is clean. After processing, the fuel will be loaded into the fuel store of the biomass boiler. Consistent fuel delivery will be ensured by a fuel extraction screw, a type of auger, which will transfer the wood chip fuel from the fuel store into the combustion chamber of the biomass boiler. Renewable thermal energy generated by the combustion of the wood chip fuel will be recovered in a heat exchanger where it will be transferred as hot water to the drying unit. Emissions from the biomass boiler will be discharged to atmosphere via a 5 metre high chimney.

The following comments were made in Natural England’s consultation response of 24th October 2016. SSSI – Further information required This application is in close proximity to Helmdon Disused Railway Site of Special Scientific Interest (SSSI). Natural England advises there is currently not enough information to determine if the development, as submitted, is likely to damage or destroy the interest features for which Helmdon Disused Railway has been notified. Our concerns are set out below. The interest features of the site listed above includes grassland, which may be sensitive to impacts from aerial pollutants, such as those emitted from this proposed development. The consultation documents provided do not include any assessment of air quality impacts. Natural England advises that an initial screening for air quality impacts should be completed prior to determination of this application. Simple screening tools are available via the internet or by contacting the Environment Agency. The results of this screening should inform the need for any further, more detailed assessment which may be required to fully assess the impacts of the proposal. Where screening results indicate a more detailed assessment is necessary this should be carried out and completed prior to determination.

The SSSI is a disused railway cutting and embankment that, according to its citation, “supports plant types typical of Jurassic limestone grassland, which are now scarce throughput the UK, and particularly so in Northamptonshire”. According to information from the APIS website1, current levels of nitrogen deposition at locations within the habitat, and near to the development site (24.22 kgN/ha/yr), exceed the lower critical load of 5 kgN/ha/yr, and are also close to exceeding the upper critical load of 25 kgN/ha/yr. These values are based upon 2012 to 2014 estimates of background NOX concentrations, and associated nitrogen and acidity deposition in the vicinity of the development

site. The corresponding values for acidity deposition are 1.73 keqN/ha and 0.28 keqS/ha, which are within their respective critical loads of 4.75 keqN/ha (maximum) and 3.89 keqS/ha.

It should also be noted that exceedence of a Critical Load is not a quantitative estimate of damage to a particular habitat, but represents the potential for damage to occur. There is no evidence in the available literature to indicate that the Helmdon Disused Railway SSSI is suffering as a consequence of excess nitrogen deposition from nearby sources.

The location of the biomass boiler installation and its proximity to the Helmdon Disused Railway SSSI is shown in the following figure. Five locations within the SSSI were selected for inclusion in the assessment, and are also shown in the following figure. The red star denotes the approximate location of the chimney of the biomass boiler.

The SCAIL (Simple Calculation of Atmospheric Impact Limits) website2 was used to undertake a screening assessment of the potential impact on the Helmdon Disused Railway SSSI due to emissions of NOX and SO2 from the proposed biomass boiler installation. Existing levels of nitrogen and acidity deposition, taken from the SCAIL website, are summarised in the following table.

Receptor Number

Existing Nitrogen Deposition Rate (kgN/ha)

Critical Load (kgN/ha)

% Critical Load

Existing Acidity Deposition Rate (keq/ha)

Critical Load (keq/ha)

% Critical Load

1 24.4 5.0 488 1.9 4.0 48 2 24.4 5.0 488 1.9 4.0 48 3 24.4 5.0 488 1.9 4.0 48 4 24.4 5.0 488 1.9 4.0 48 5 24.4 5.0 488 1.9 4.0 48

Due to their close proximity, current levels of nitrogen and acidity deposition are estimated to be the same at each of the five receptor locations. The above data show that current levels of nitrogen deposition exceed the lower critical load by a factor of ~4.9, while current acidity deposition rates are about half of the critical load.

As stated above, exceedence of a Critical Load is not a quantitative estimate of damage to a particular ecological habitat, but represents the potential for damage to occur. There is no evidence in the available literature to indicate that the Helmdon Disused Railway SSSI is suffering as a consequence of currently estimated nitrogen and acidity deposition from nearby sources.

and are summarised in the following table, and appended to this report (APPENDIX 1).

Parameter Biomass Boiler Chimney Height (m) 5.0 Diameter (m) 0.16 Efflux Temperature (ºC) 112 Efflux Velocity (m/s) 4.6 NOX Emission Rate (g/s) 0.021 (142 g/GJ) SO2 Emission Rate (g/s) 0.003 (21 g/GJ) Location (x,y) 458430,242242

The NOX and SO2 discharge rates were calculated from their respective emission factors (g/GJ) and based upon the thermal input to the 130 kWth(output) biomass boiler (GJ/s), assuming 90% boiler efficiency.

In line with the SSSI citation the assessment was carried out on the basis of the habitat characteristics of the Helmdon Disused Railway SSSI being calcareous grassland. The SCAIL website was used to calculate nitrogen and acidity deposition at the five above locations within the SSSI, and the results are presented in the following table.

Receptor Number

Nitrogen Deposition Rate (kgN/ha)

Critical Load (kgN/ha)

% Critical Load

Acidity Deposition Rate (keq/ha)

Critical Load (keq/ha)

% Critical Load

1 ~0.057 5.0 ~1.1 ~0.0063 4.0 ~0.16 2 ~0.052 5.0 ~1.0 ~0.0056 4.0 ~0.14 3 ~0.033 5.0 ~0.7 ~0.0035 4.0 ~0.09 4 ~0.024 5.0 ~0.5 ~0.0026 4.0 ~0.07 5 ~0.015 5.0 ~0.3 ~0.0015 4.0 ~0.04

As can be seen, the Process Contribution (increase in nitrogen deposition due to emissions of NOX from the biomass boiler) is ~1% or less of the lower critical load of 5 kgN/ha at all five of the receptor locations within the Helmdon Disused Railway SSSI. In line with Environment Agency guidance3 an increase of this magnitude can be screened out as insignificant. The corresponding values at locations father away would be proportionately lower in relation to their distance from the biomass boiler chimney. The above screening assessment confirms the insignificance of the impact of emissions from the biomass boiler on nitrogen deposition within the Helmdon Disused Railway SSSI. Similar conclusions can be drawn for the impact of emissions from the biomass boiler on acidity deposition within the Helmdon Disused Railway SSSI, where process contributions are ~0.2% or less of the site-specific critical load.

Accordingly, the incremental increase in nitrogen and acidity deposition attributable to emissions from the proposed biomass boiler installation at Blackpitts Barn Farm is likely to be small, and is unlikely to have a measurable effect on the integrity of the Helmdon Disused Railway SSSI. In line with Environment Agency guidance, generally accepted by Natural England as the basis for determining significance for air quality impacts at ecological receptors, the impact of emissions of NOX and SO2 from the proposed biomass boiler installation, on nitrogen and acidity deposition within the Helmdon Disused Railway SSSI, can be screened out as insignificant.

I hope that the above information responds in sufficient detail to the consultation comments received from Natural England, and will enable Northampton County Council to approve the planning application for the biomass boiler installation at Blackpitts Barn Farm.

If I can be of further assistance, or if you or anyone from Natural England has any questions relating to the above screening assessment, then please feel free to call me on the office telephone number at the head of this letter.

Yours sincerely
