  5. 5. North Doncaster Chord Environmental Statement1. Introduction1.1 BackgroundThis Non-Technical Summary (NTS) provides a summary of the Environmental Statement (ES) whichaccompanies an application for a Development Consent Order to the Infrastructure Planning Commission(IPC) for the proposed North Doncaster Chord scheme. Network Rail commissioned Mott MacDonald toassist with the delivery of the detailed design for the proposed chord.The scheme consists of a new railway viaduct over the East Coast Main Line (ECML) and 3.2 kilometres(km) of associated railway line connecting two freight lines, the Askern line and the Skellow line. As part ofthe scheme, Network Rail is also proposing to provide a highway bridge over the ECML to the north ofJoan Croft level crossing. Once the highway bridge has been completed, it is the intention to close theJoan Croft level crossing. This is designed to increase the capacity of high speed traffic on the ECML, aswell as enhancing freight movements on both the Skellow and Askern lines.1.2 Role of the Environmental StatementAn Environmental Impact Assessment (EIA) involves the collection of extensive environmental informationto help identify and assess any environmental effects that are likely to arise from the proposed scheme.The Environmental Statement (ES) reports the findings of the EIA and has been prepared to accompanythe application for a Development Consent Order.The ES reports: any significant environmental effects that the North Doncaster Chord scheme may have; the means of mitigating these effects, where appropriate; and any significant residual effects which remain after mitigation has been applied.A significant effect is one that, in the opinion of the EIA specialists, needs to be brought to the attention ofthe decision maker; in this instance, the IPC. It may be beneficial or adverse, and temporary or permanent.Mitigation measures are actions that are implemented to reduce the significance of an environmental effect.The effect that remains after the implementation of mitigation measures is known as the significant residualeffect.This Non-Technical Summary provides an overview of the main findings of the ES for the North DoncasterChord scheme. 1
  6. 6. North Doncaster Chord Environmental Statement2. LocationThe site of the proposed scheme is located approximately 5 km north of Doncaster, South Yorkshire asshown in Figure 1. The purple shading depicts the approximate extent of the construction corridor for theroute of the new chord.Figure 1: Site Location Askern Line Askern Line ECML ECML Applehurst Chord Applehurst Chord Skellow Line Skellow Line South to Doncaster Town Centre South to Doncaster Town CentreSource: Mott MacDonald, 2011 2
  7. 7. North Doncaster Chord Environmental Statement3. Need for the North Doncaster Chord3.1 Need for the North Doncaster ChordThe ECML provides a rail link between London and Scotland and is becoming increasingly busy. Freighttrains currently join the ECML passenger line from Applehurst Chord (see Figure 1). Over the past decade,there has been a 35% increase in passengers travelling between Doncaster and York and a 60% increasein the amount of freight carried by rail across the UK, and passenger growth is expected to continue.The proposed scheme allows freight trains to travel on a flyover over the ECML and therefore removingslow moving freight trains from the busy ECML. By removing the freight trains, there will be moreopportunities for increased passenger services on the ECML in the future.3.2 Scheme BenefitsCreating a new railway that crosses over the ECML will support national Government policies on climatechange, air quality and train service performance as outlined in ‘The Case for Rail, 2007.’ This is just one ofthe projects that make up part of a programme of works to create extra capacity on the ECML by removingslow moving rail freight trains.The benefits associated with the project include increased passenger numbers, and a consequentialincrease in revenue, through greater reliability. In North Doncaster, the proposed scheme will: create extra capacity to run more passenger services on the ECML; create the potential for extra freight trains to run, taking more traffic off roads; an average freight journey typically takes approximately 50 lorry journeys off the road; environmental benefits relating to reduced road traffic emissions if more freight is carried by train rather than by road; and increase the frequency and improve long distance passenger services throughout the day.In addition, it is expected that there will be wider socio-economic benefits arising from the scheme throughimprovements to passenger rail services. These improvements will allow easier access for business traveland recreational opportunities in other towns and cities.3.3 Consideration of AlternativesThe North Doncaster Chord scheme has been in development since 1997 and during this time a widerange of different engineering layouts and options have been considered, including do nothing, timetableamendments, consideration of alternative routes in the nearby region, etc. However, alternatives to thelocation of the scheme are limited due to the overall aim of removing freight from the ECML in this area,and provision of a direct link between the Askern and Skellow lines was determined to be the obvioussolution. Whilst slightly varying alignments of the new chord have been considered, the general location ofthe chord has been relatively fixed since commencement of design work on the scheme.The design of the North Doncaster Chord scheme has included a range of feasibility studies, signallingconsiderations, environmental assessments etc. This has resulted in consideration of a number of differentoptions. The recommended option was amended during the design process to include a highway bridgefollowing public consultation undertaken in June 2010. 3
  8. 8. North Doncaster Chord Environmental StatementIn addition to the alignment, consideration has also been given to a number of alternatives concerning theconstruction access routes, type of viaduct structure and embankment fill that will be used in the scheme.As part of this process, the results from the environmental surveys were used to influence the design andreduce environmental impact. This has included using the results of the ecology and tree surveys toposition passing places on Rockley Lane and Holme Lane to avoid the need to remove mature trees. Theintroduction of the highway bridge in the scheme has also allowed a reduction in height of the viaduct andassociated embankments, which helps to reduce the visual impact of the proposed scheme. 4
  9. 9. North Doncaster Chord Environmental Statement4. Scheme Overview4.1 Site AreaThe site is located approximately 5 km north of Doncaster, South Yorkshire as shown in Figure 1 above.The area where the proposed scheme is to be located is predominantly rural, with the surrounding landused mostly for agricultural purposes as shown in Figures 2 to 4 below.Figure 2: Existing view looking north-west from Bell Croft LaneSource: Mott MacDonald, 2010Many of the fields in the area are bordered by mature hedgerows and occasional trees and the roads whichpass through the area are narrow, single track roads with occasional passing places. The area is alsocrossed by several existing railway routes. This includes the busy ECML, in addition to the Skellow freightline and the Askern Line, which is predominantly freight but has a limited number of passenger serviceseach day. As a result, there are numerous existing level crossings in the area; some of them are for useonly by farm vehicles, whilst others are located on the roads passing through the area such as thecrossings over the ECML and the Askern Line on Joan Croft Lane. 5
  10. 10. North Doncaster Chord Environmental StatementFigure 3: Existing view looking south-west from Airey LaneSource: Mott MacDonald, 2010The main feature of the landscape aside from the railway infrastructure is the currently disused ThorpeMarsh Power Station, which is located directly south of the Skellow Line. Thorpe Marsh Power Ltdsubmitted an application in February 2010 to the Department of Energy and Climate Change under theElectricity Act to build a new combined cycle gas turbine (CCGT) power plant on the site of the old ThorpeMarsh Power Station. There is a possibility that the construction programme for the CCGT plant will overlapwith the proposed construction programme for the North Doncaster Chord scheme. However, it isconsidered that the key cumulative impacts of the two schemes will relate solely to construction effectsresulting from a temporary increase in construction-related road traffic. Ongoing consultation is being heldbetween Network Rail and Thorpe Marsh Power Ltd to aim to minimise any potential cumulative impacts.Figure 4: Existing view looking west from Thorpe Gates towards Joan Croft level crossingSource: Mott MacDonald, 20104.2 Environmental DesignationsAccording to the Doncaster Metropolitan Borough Council (DMBC) Unitary Development Plan (UDP) landallocation map, all land to the west of the ECML is designated as greenbelt land. Part of the new railwaywill therefore be located within land classified as greenbelt. 6
  11. 11. North Doncaster Chord Environmental StatementThe proposed scheme does not intrude into any environmentally designated sites.There are a number of designated sites located within 2 km of the proposed North Doncaster Chord andthe construction haul routes including Owston Hay Meadows and Shirley Pool Site of Special ScientificInterest.4.3 Scheme DescriptionThe scheme combines the construction and operation of a new railway flyover over the ECML (referred toas a chord) from the Skellow Line to the Askern Line in the vicinity of Joan Croft level crossing, north ofDoncaster. As part of the scheme, Network Rail is proposing to close Joan Croft level crossing and replacethis with a highway bridge over the ECML, as shown in Figure 5 below.Figure 5: Visualisation of proposed scheme, showing new highway bridgeSource: Mott MacDonald, 2010The new chord will consist of two embankments from the Askern and Skellow lines leading to a multi-spanviaduct which crosses Joan Croft Lane and the ECML, as shown in Figure 6 below. 7
  12. 12. North Doncaster Chord Environmental StatementFigure 6: Visualisation of proposed scheme, showing new viaductSource: Mott MacDonald, 2010The new multi-span viaduct and highway bridge will be constructed from steel and concrete. Deliveries offill material required for the embankments will be partly by rail to reinstated sidings located to the east ofthe ECML to help minimise the number of road deliveries needed. 8
  13. 13. North Doncaster Chord Environmental Statement5. Construction, Operation and Decommissioning5.1 ConstructionA detailed construction plan documents the order and timing of construction activities including therefurbishment of the rail sidings at Thorpe Marsh Power Station, signalling works, highway improvements,site clearance, earthworks and the construction of the viaduct and highway bridge.It is anticipated that construction works will commence in July 2012 for advance works which will includethe diversion of utilities and setting up site accommodation. The main construction works will take placeover a 17 month period between December 2012 and April 2014. The core construction working hours willbe from 0700 hours to 1900 hours Monday to Friday and from 0800 hours to 1300 hours on Saturdays,although there may be some night time deliveries by rail to the reinstated sidings.In addition to the scheme specific mitigation and best practice guidance, Network Rail is committed toenvironmental protection and this is managed predominantly by the Contract Requirements – Environmentdocument, which all contractors involved in the scheme will be required to abide by.5.2 OperationIt is the aspiration to increase the number of off peak Long Distance High Speed (LDHS) services on theECML from 6 trains to 7 trains per hour and for high peak trains from 6 trains to 8 trains per hour. TheNorth Doncaster Chord scheme allows freight traffic to be routed to a more direct route avoiding the ECML,enabling paths to be used by passenger services in line with predicted growth demands.5.3 DecommissioningDecommissioning has to be considered as part of the design life cycle, in line with the Waste Managementplan in accordance with Contract Requirements – Environment documentation and other Network Railguidance notes, the railway structures are designed for 120 years, taking into account regular routinemaintenance. In the event that the viaduct and highway bridge are removed at some point in the future, itshould be possible to separate the individual materials for potential reuse or recycling due to the relativelysimple construction materials of the railway chord and viaduct. Fill material to be used for embankmentconstruction could also be reused where appropriate and in accordance with the Waste Management planand Network Rail’s environmental management objectives for recycling. 9
  14. 14. North Doncaster Chord Environmental Statement6. Environmental Impact Assessment6.1 EIA ScopingAn EIA Scoping Report was prepared for the scheme and formally submitted to the IPC in July 2010. Theobjective of the scoping exercise was to identify which aspects of the scheme are likely to give rise toenvironmental effects, and to determine the scope of work required for the preparation of the ES. The IPChas a duty to consult widely before adopting a scoping opinion. The IPC circulated the scoping report to awide range of consultees including the relevant statutory undertakers, such as Natural England, and localauthorities to seek the views from consultees on the scope and method of the EIA.The Scoping Opinion was provided by the IPC in September 2010. The Scoping Opinion indicated thatoverall, the IPC was satisfied that the topics identified in the EIA Scoping Report were suitable for thescheme.In addition to the formal scoping consultation process, ongoing liaison has been undertaken with relevantbodies during the design process to address particular aspects during the scheme design anddevelopment. For example, this has included discussions with the Environment Agency to incorporateconsideration of the flood plain and to aid in the creation of an appropriate drainage design for the scheme.6.2 EIA ConsultationConsultation has been undertaken throughout the scheme development process providing opportunities forothers including the general public to influence and inform the proposals.This has included: ongoing liaison with members of DMBC; public consultation including exhibitions, flyers and questionnaires; meetings with local landowners; meetings with statutory consultees; information in the local press; and community workshop.6.3 Planning PolicyNational, regional and local planning and other policies relevant to the EIA for the scheme were identified.These policies were reviewed to assess compliance of the proposed scheme with all regulations. APlanning Statement has been produced and will accompany the planning application to providecommentary on how the proposed development aligns and is compliant with all relevant policies.6.4 Environmental EffectsA summary of the findings of the technical assessments undertaken for the North Doncaster Chord EIA ispresented below.6.4.1 Air QualityIn line with best practice, the air quality assessment has considered vulnerable receptors, focusing onresidential properties located near to the proposed scheme. The construction assessment has focused on 10
  15. 15. North Doncaster Chord Environmental Statementchanges in air quality from construction dust and traffic emissions. The operational assessment hasconsidered the potential for the scheme to influence traffic flows and generate air pollutants. Operationaleffects have been scoped out from further consideration as no significant effects were predicted.Construction EffectsNetwork Rail requires all contractors to abide by their specific requirements for controlling dust emissionsthrough implementation of the Nuisance Management Plan. Measures will be put in place to avoid creationof significant effects caused by dust from the scheme, including damping down stock piles of earth withwater, wheel washing and covering up of supplies, enclosed rubble chutes, use of prefabricated materialsto minimise grinding, sawing and cutting on site and ensuring compliance through site inspections. Thecontractor will be required to strictly adhere to the Nuisance Management Plan and these dust controlmeasures as part of the incorporated mitigations. Such measures will help towards prevention ofsignificant air quality effects on the local residential properties.Operational EffectsThe proposed scheme is not predicted to significantly affect traffic flows on local roads, nor will itsignificantly alter the nature or location of locomotive emissions. Further evidence of this was obtainedthrough a detailed traffic assessment; see section 6.4.8 of this Non Technical Summary.Residual EffectsOn the assumption that appropriate mitigation measures are implemented, as outlined within theEnvironmental Statement, it is considered that there will be no significant adverse residual effects on airquality within the study area.6.4.2 CommunityNetwork Rail has undertaken engagement and consultation activities to identify the issues that areimportant to local residents, landowners and other stakeholders. The issues raised by members of thecommunity during the engagement and consultation have helped to inform the design of the scheme,including the selected construction access routes and the inclusion of the highway bridge in the scheme.Construction EffectsThe proposed scheme is expected to create around 50 additional construction jobs, and will have abeneficial impact on employment. The temporary use of farm land for construction activities is likely toresult in a disruption to farming activities and this is expected to have an adverse effect on local farmers.Effects on journey times, public rights of way and other indirect effects have been assessed and are notconsidered to be significant.Operational EffectsThe closure of Joan Croft level crossing will result in the redeployment of Network Rail staff currentlyworking at this site. The replacement of the level crossing with a highway bridge is likely to result in abeneficial effect on the local community from more reliable and shorter journey times. 11
  16. 16. North Doncaster Chord Environmental StatementResidual EffectsThe assessment of community effects has identified potentially significant residual effects during theconstruction phase and the operational phase. The construction phase is predicted to result in beneficialeffects from employment and adverse effects from disruption to agricultural activity. The operational phaseis predicted to result in adverse effects from a possible loss of jobs and beneficial effects from improvedaccess for the community from the replacement of Joan Croft level crossing with a highway bridge.6.4.3 EcologyThe assessment takes into account the combined results of a desk-based assessment and protectedspecies surveys to identify the presence of ecological features of importance within the areas of theproposed scheme.The scheme will not have an impact on any designated sites and the scheme design was amended toavoid any effects on trees of high ecological importance resulting from the new passing places for the haulroutes. Protected species surveys identified the presence of bats, badgers, reptiles and great crestednewts (see Figure 7) within the study area.Construction EffectsWork associated with the construction phase of the scheme will have an adverse effect on habitats due tothe removal or infilling including hedgerows, scrub, scattered trees, grassland and ditches. Speciesaffected by the construction phase include the temporary removal of terrestrial habitat of great crestednewts, foraging habitat for badgers, reptiles and bats, and potential nesting habitat for birds. Mitigation hasbeen incorporated into the scheme design in order to reinstate habitats prior to the operational phase toreduce these effects to an acceptable level. Figure 7: Great Crested Newt surveys undertaken as part of the EIA Source: Mott MacDonald, 2010 12
  17. 17. North Doncaster Chord Environmental StatementOperational EffectsWork associated with the operational phase of the scheme will have an adverse effect on habitats due totheir permanent loss including hedgerows, scrub, scattered trees, ruderal, grassland and ditches, althoughthis has been minimised through careful design iteration. Species will be affected by the operational phasedue to the permanent loss of the terrestrial habitat of great crested newts, foraging habitat of badgers,reptiles and bats and nesting habitat for birds. Incorporated mitigation to reinstate habitats and creatingplanting to maintain foraging and commuting flight lines for bats will reduce these effects to an acceptablelevel.Residual EffectsFollowing incorporated mitigation, there are no significant residual impacts predicted for any of theecological features in the North Doncaster Chord study area during either construction or operation.6.4.4 Geology and SoilsThe ground conditions beneath the site are variable, although the investigations completed along theproposed route have not identified the presence of any contamination.Construction EffectsThe construction works will involve the disturbance, excavation and movement of soil during generalearthworks and ground improvement. The adoption of best practicable means during construction willminimised potential risks to construction workers from exposure to any previously unidentifiedcontaminants. In addition, the contractor will be required to follow guidance from the Environment Agencyon ground works to mitigate the risk to groundwater.With regards to geology, the implementation of an earthworks specification will help any excavated materialto be reused on site where possible.Operational EffectsIt is not anticipated any ground contamination will be caused by normal operation of the new chord, otherthan in the event of an emergency. Assessment of operational effects on geology and soils has thereforebeen scoped out of this EIA.Residual EffectsOn the assumption that appropriate mitigation measures are implemented, as outlined within theEnvironmental Statement, it is considered that there will be no significant adverse residual effects onground conditions within the study area.6.4.5 Historic EnvironmentThe historic environment assessment included desk-based research and a geophysical survey to identifythe potential for previously unrecorded remains. The assessment concluded that the proposed schemewould not have an impact on any designated heritage assets or non-designated assets of nationalimportance. 13
  18. 18. North Doncaster Chord Environmental StatementConstruction EffectsConstruction work associated with the scheme will have an effect on several locally important historicallandscape features, such as a parish boundary, and a green lane (as shown in Figure 8 below). Mitigationmeasures will include checks by an archaeologist during excavation works in sensitive areas, photographicrecording and hedgerow reinstatement. Figure 8: Honey Lands Lane – a characteristic “green lane”, looking south-east towards Thorpe Marsh power station Source: NAA, 2010Incorporation of survey findings during the design process has enabled the route of the temporaryconstruction access road off Holme Lane to be changed to avoid any impact on the well-preserved ridgeand furrow earthworks (as shown in Figure 9). 14
  19. 19. North Doncaster Chord Environmental Statement Figure 9: Surviving ridge and furrow earthworks in a small paddock located to the rear of Holme Cottage, looking north-west towards Holme Lane Source: NAA, 2010Operational EffectsThe visual setting of the former railway cottages at Joan Croft Junction will be affected by the operation ofthe new viaduct and highway bridge. Mitigation through sympathetic planting to form a screen on theproposed embankments has been incorporated to reduce the effect on these cottages within 15 years ofoperation.Mitigation will reduce, but not totally remove, adverse effects on the character of the historic landscape.These effects will be associated with the loss of sections of the historic boundaries, including the parishboundary. The operational effect on the cottages at Joan Croft Junction will reduce as the mitigationplanting matures, as shown in Figures 10 and 11 below. The adverse effect on any sub-surfacearchaeological remains will be off-set by the beneficial effect of the archaeological investigations providinginformation that could lead to an improved understanding of past activities in this area.Residual EffectsSignificant residual effects will remain following mitigation during construction the construction phase as aresult of the loss of sections of historic field boundaries and a parish boundary. There will also be asignificant adverse effect during operation as a result of the changes to the setting of the unlisted buildingsof local historic interest at Joan Croft Junction. However, these effects will gradually reduce in significanceduring operation as trees planted as part of the scheme mature, reducing the visual intrusion of thestructures. 15

There are no conservation areas within thesite of the proposed scheme; however the western part of the site lies within an Area of Special LandscapeValue (ASLV). In addition, there are a small number of nearby houses affected by the proposed schemeand the Trans Pennine Trail crosses the site. A Landscape Character Assessment was undertaken todetermine the value of the landscape, both of character areas and individual features and elements.Construction EffectsAn iterative design process has ensured that the design has a minimum impact on landscape features suchas mature trees and hedgerows during the construction phase. Where hedges are removed for theconstruction of the haul roads, new hedgerows will be planted in replacement.Operation EffectsIt is considered that the operation effect on landscape and visual amenity as a result of the NorthDoncaster Chord scheme will have some significant effects. This is because two significant structures,namely the viaduct and highway bridge, will be constructed in a relatively rural landscape. However, theplanting of trees and hedgerows in areas surrounding the scheme and on the embankments will help to 16
  21. 21. North Doncaster Chord Environmental Statementscreen the structures from nearby residential properties and public rights of way. The effect of the viaductand highway bridge can only be mitigated to a certain extent by planting due to the height of the structuresabove ground level. Figures 12 to 15 show how the scheme will look, from different viewpoints, withmitigation planting in Year 1 and Year 15.

However, the level of these visual effectswill reduce in time as the landscape planting to be provided as part of the scheme matures and thestructures become more integrated into the local landscape.6.4.7 Noise and VibrationDue to the rural location of the proposed scheme, the noise level in the area of dwellings close to thescheme extents is relatively tranquil in the absence of noise from the existing railways. The noise andvibration monitoring (as shown in Figure 16) and assessment examined the potential effects on residentialproperties due to the construction and operation of the proposed scheme. 18
  23. 23. North Doncaster Chord Environmental Statement Figure 16: Noise monitoring undertaken as part of the EIA Source: Mott MacDonald, 2010Construction EffectsConstruction works will be limited to weekday daytime and Saturday morning periods, although somelimited activities will need to be undertaken at night to avoid disruption of rail services, in addition topossible night time delivery of fill materials by train. The contractor will minimise any disturbance inaccordance with best practice and consideration of factors identified within the Construction EnvironmentalManagement Plan and Nuisance Management Plan to be prepared for the works. The assessment showedthat overall average noise levels from construction works that are expected to occur during the daytimewould not exceed the lowest threshold for significant effects at dwellings.Construction methods expected to be used in the railway and road bridge embankment works are unlikelyto cause disturbance at the nearest dwellings. Some short term noise and vibration effects are expected atthe closest residential properties during night works, otherwise there will be no significant noise andvibration effects on residential properties during construction. Noise and vibration from construction traffic isnot expected to be significant, provided movements accessing the site are restricted to normal daytimehours of work.Operation EffectsOperational noise and vibration effects resulting from the proposed scheme are mainly associated with thetransfer of freight trains from the ECML to the proposed chord. The assessment accounts for noise fromadditional passenger trains that could run on the ECML in place of freight trains. The assessmentconcluded that there is an increase in noise at two residential properties to the north end of the proposedscheme and a reduction in noise at the four residential properties at Joan Croft level crossing, which arecurrently exposed to the highest levels of railway noise. Network Rail is committed to minimisingdisturbance from the railway and a detailed assessment for the entitlement to noise insulation will beundertaken. 19
  24. 24. North Doncaster Chord Environmental StatementResidual EffectsAlthough mitigation measures will reduce noise and vibration levels, it is anticipated that there will be asignificant residual effect as a result of an increase in operational railway noise at Crossing Gate Farm, andto a lesser extent at Blacker Green Farm.6.4.8 Traffic and TransportThe traffic and transport assessment considered the potential effects of construction and operational trafficin terms of other road users including pedestrians, cyclists and equestrians. Detailed traffic surveys havebeen undertaken through consultation with DMBC in order to define existing traffic flows in the study area.The local road network has been identified as comprising of rural roads which are often narrow with tightcorners and limited passing places, and the amount of traffic which can use them is therefore restricted.The Trans Pennine Trail runs through the area and is popular with pedestrians, cyclists and equestrians,especially during the summer months.Construction EffectsEffects on other road users will result from construction traffic which will need to access both the east andwest sides of the site. Improvements to the existing roads, appropriate scheduling of traffic movements,creation of temporary sections of haul roads and the use of the rail network for the delivery of fill will help tominimise the impacts from construction traffic.Operational EffectsOnce the scheme is operational, the highway bridge at Joan Croft will allow more reliable access to theproperties in the local area. This will also provide a safety benefit through removal of the interface of a roadtraffic with a busy railway line.Residual EffectsOn the assumption that appropriate mitigation measures are implemented, as outlined within theEnvironmental Statement, it is considered that there will be no significant adverse residual effects on trafficflows within the study area.6.4.9 Waste ManagementThe scheme will develop a Waste Management Plan to manage waste generated during construction andwill adhere to relevant waste management policies. Operational waste effects were scoped out fromfurther consideration as no significant effects were predicted.Construction EffectsConsiderable volumes of material will be generated during construction, including spoil from excavationworks and off-cuts of construction materials such as concrete, bricks, metal and packaging waste. Materialwill need to be reused on site wherever possible to aid the construction and landscaping process.Inevitably, some material which cannot be reused or recycled will be removed from the site for disposal;however, opportunities for recycling will be maximised. Any contaminated materials will be removed from 20

A Waste Management Plan will be developed toensure that waste management procedures and environmental risks are minimised.Residual EffectsOn the assumption that appropriate mitigation measures are implemented, as outlined within theEnvironmental Statement, it is considered that there will be no significant adverse residual effects on wastemanagement as a result of the scheme.6.4.10 Water ResourcesThe assessment on water resources considered the potential effects on surface water and groundwater interms of water quality, changes in flows, changes in groundwater levels and flood risk relating to theproposed scheme. A separate flood risk assessment was also prepared in support of the water resourcesassessment.Construction EffectsThe River Don and its tributary Ea Beck are located to the south and east of the site. These are unlikely tobe affected by construction. Numerous ditches managed by the Internal Drainage Board also cross theproposed site. These ditches may be affected by contamination from construction activities. An alluviumand a sandstone aquifer are also located under the site. Across much of the site, the sandstone isprotected by a layer of impermeable deposits, which limit the transfer of water from the surface to theunderlying sandstone. In the area of the proposed scheme the only potential pathway for surface water toreach the bedrock is via piling activities which will be used to construct the viaduct and highway bridge. Inthis area, the sandstone aquifer is not used for water supply.Industry guidance and Network Rail’s Contract Requirements – Environment documentation will befollowed to limit the risk of contamination of the groundwater in the aquifer. A Pollution Incident ControlPlan will also be developed in order to help limit/contain any pollution; on this basis, there should be noeffects on water resources during the construction phase.Operational EffectsThere are not anticipated to be any operational effects on water resources.Residual EffectsOn the assumption that appropriate mitigation measures, as outlined within the Environmental Statement,are implemented, it is considered that there will be no significant adverse residual effects on waterresources within the study area. 21
  26. 26. North Doncaster Chord Environmental Statement7. ConclusionsThe environmental assessment has identified that, through careful design and implementation ofappropriate mitigation measures, significant adverse effects on the environment can be largely avoided.However, whilst Network Rail is committed to implementing appropriate mitigation measures for thescheme, mitigation cannot entirely prevent residual effects, given the size and scale of the structures andthe topography and rural nature of the surrounding landscape.The main environmental effects arise from introduction of the two structures which form part of the scheme,namely the viaduct and highway bridge. The visual impact of these structures during both construction andoperation can only be reduced to a certain extent by screening and planting due to the height of thestructures above ground level. As a result, there will be an adverse effect on the views of this area fromproperties within close proximity of the structures and from some of the local rights of way which pass closeto the existing Joan Croft level crossing. The presence of the new structures will also affect the setting ofthe railway cottages at Joan Croft, which are properties of local historic interest. However, the level of thesevisual effects will reduce in time as the landscape planting to be provided as part of the scheme maturesand the structures become more integrated into the local landscape.Additional residual environmental effects comprise the loss of sections of historic field boundaries and aparish boundary during the construction works, and the permanent diversion of a bridleway as a result ofthe closure of the Owston Grange crossing. An increase in railway noise is also expected at Crossing GateFarm due to operation of the new chord, and to a lesser extent at Blacker Green Farm.The scheme will also have beneficial environmental effects arising from reduction in journey times as aresult of the new highway bridge and potential employment opportunities during the construction phase. Inaddition, the scheme will provide efficiencies for freight train services using the North Doncaster Chord andwill contribute to the overarching aim to increase capacity on the ECML, which may lead to an increase inthe use of rail services over road or air travel. As such, the scheme is predicted to have a beneficial effectwith respect to carbon dioxide emissions and climate change.7.1 Your CommentsThe full ES and supporting documents will be made available for public inspection at suitable locationsincluding the following: Doncaster Borough Council office: Council House, College Road, Doncaster, DN1 1BR; Askern Library, Station Road, Askern, Doncaster, DN6 0JA; Post Office (Barnby Dun), 2 Stainforth Road, Barnby Dun, DN3 1AA; and Central Library, Waterdale, Town Centre, Doncaster.The full set of ES documents can also be purchased from Network Rail at the address identified on thefront of this NTS document.
