1 BACKGROUND AND CONTEXT
1.1 INTRODUCTION 1.1.1. Shropshire Council, as Highway Authority (hereafter referred to as ‘the Applicant’) is seeking to obtain planning permission for the proposed North West Relief Road (hereafter referred to as ‘the Proposed Scheme’) in Shrewsbury. The Proposed Scheme would be a single carriageway road with at-grade junctions, linking the A5 Shrewsbury Southern Bypass with the A5124 Battlefield Link Road. 1.1.2. WSP UK Limited (hereafter referred to as ‘WSP’) has been commissioned by the Applicant to undertake the preliminary design of the Proposed Scheme and to prepare an Environmental Statement (ES) as part of the Environmental Impact Assessment (EIA) process. This Outline Construction Environmental Management Plan (CEMP) has been prepared in support of the detailed planning application and outlines the environmental measures that will be undertaken by the Contractor of the Proposed Scheme during the construction phase. 1.1.3. The area of works required for the construction of the Proposed Scheme (hereafter referred to as ‘the Construction Site’) is approximately 120ha and is identical in size and extent with the Application Boundary for which planning permission is sought for. The Construction Site is shown in Annex A. 1.2 PURPOSE OF THE CEMP 1.2.1. This CEMP specifies the overarching construction management measures the Principal Contractor would implement in order to avoid or reduce environmental impacts during the construction phase of the Proposed Scheme. 1.2.2. This CEMP will inform the production of a final management plan that will be submitted to the Planning Authority for approval prior to the commencement of construction of the Proposed Scheme. This eventual document will be a live document and will be maintained by the Principal Contractor and reviewed and updated on a regular basis throughout the construction phase as new environmental construction measures are identified and implemented. 1.3 LEGAL COMPLIANCE 1.3.1. Considerable environmental legislation applies to the works to be undertaken. The expectation is that all relevant legislation, including requirements for licences, permits and/or consents will be identified by the Applicant and applied for at a later stage in the development of the Proposed Scheme. Working alongside the Principal Contractor the Applicant will identify what these consents are, who is best placed to obtain them and, following the detailed design process what project specific information is available to address the nature of information that these licences, permits and consents require. 1.3.2. For each relevant environmental aspect, the applicable environmental legislation and regulations would be identified from, but not limited to the list provided in Annex B. The list of relevant legislation and its applicability to the Construction Site and the works would be reviewed and updated where necessary by the Principal Contractor.

2 PROPOSED SCHEME DESCRIPTION
2.1.1. The Proposed Scheme comprises a new 7.3m wide single carriageway all-purpose 6.9km long road with a permitted speed of 60mph, along with associated landscaping and drainage. As a result of the severance of a number of local roads, footpaths and public rights of way (PRoW), a combined footway and cycleway would be provided, adjacent to the carriageway, with linkages to existing non- motorised user routes. The Proposed Scheme includes three new structures over the carriageway. Clayton Way would be diverted over a new bridge and would be designed to accommodate vehicles and all non-motorised users and the existing PRoWs in proximity to Shepherd’s Lane and Marches Way, would be diverted onto new bridges. In addition, at the B4380 Holyhead Road Roundabout the existing bridleway and footpath would be diverted underneath the Proposed Scheme via an underpass. 2.1.2. A climbing lane would be provided on the westbound approach to the proposed B4380 Holyhead Road Roundabout which would cross the River Severn and floodplain on an approximately 670m long viaduct. A second bridge crosses the Shrewsbury to Chester railway. Two flood storage areas would be provided to compensate for the loss of flood storage. 2.1.3. The Proposed Scheme includes two new roundabout junctions (one at the B4380 Holyhead Road and the other at the B5067 Berwick Road) and the improvement of two existing roundabouts (the A5 Churncote Roundabout and the A528 Ellesmere Road Roundabout). Traffic calming measures would be installed along Welshpool Road. PROPOSED ROUNDABOUT WORKS
A5 Churncote Roundabout (National grid reference 344766, 313518) alteration of the existing 4-arm roundabout to a 5-arm roundabout with the addition of an entry and exit to/from the Proposed Scheme; B4380 Holyhead Road Roundabout (National grid reference 346472, 313728) construction of a new roundabout enabling local traffic to access the Proposed Scheme as well as retaining the current thoroughfare and adding greater local connectivity; B5067 Berwick Road Roundabout (National grid reference 348146, 314356) construction of a new roundabout which would provide better links to the Shrewsbury Show Ground and Shrewsbury Railway Station; and A528 Ellesmere Road Roundabout (National grid reference 349688, 316563) alteration of the existing roundabout with the addition of a further roundabout to form a ‘dumb-bell’ arrangement. The existing 5-arm roundabout would become a 4-arm and an additional 4-arm roundabout would be included on the line of the Proposed Scheme to the south-west. The dumb-bell arrangement will allow the existing roundabout to remain in its current location. The existing roundabout would retain the arm to/from A528 Ellesmere Road to the north, the Battlefield Link Road and Knights Way. A new arm would be added to link with the proposed new roundabout. The proposed new roundabout would include arms to/from A528 Ellesmere Road to the south, Huffley Lane and to the Proposed Scheme as well as the link to the existing roundabout. Connectivity to Harlescott Lane would be maintained by way of a T-junction on to Ellesmere Road (south), similar to the existing arrangement.

PROPOSED STRUCTURES
Shepherd’s Lane Footbridge (National grid reference 345463, 313712) this single span bridge is proposed to accommodate pedestrians and cyclists which would help maintain connectivity and ensure safety with no formal at grade crossing; Clayton Way Overbridge (National grid reference 346025, 346025) this single span multi girder deck bridge is proposed to accommodate all road and non-motorised users, including equestrians, and to be part of the public highway; Equestrian Culvert East of Holyhead (National grid reference 46573, 313704) this multi- purpose underpass would maintain connectivity for pedestrian, equestrians and mammals close to existing routes for each of these; Shelton Rough River Severn Viaduct (National grid reference 346851, 313642) this structure would span over the River Severn. The total span would be approximately 660m; Willow Pool Wildlife Culvert (National grid reference 347810, 314093) to provide mammal crossing and serve as an overflow channel; Alkmund Park Culvert (National grid reference 34831, 314691) crossing an existing natural drainage ditch close to Alkmund Park Wood and would also act as a wildlife corridor for mammals; Marches Way Accommodation Overbridge (National grid reference 348530, 315205) the structure would comprise a single span ladder deck bridge which would maintain access for landowners and farmers and also serve as a safe crossing for pedestrians; Hencott Railway Bridge (National grid reference 348594, 315351) the structure would be a simply supported highway bridge crossing the Shrewsbury to Chester railway; and Hencott Pool Culvert (National grid reference 349338, 315811) crossing an existing natural drainage ditch south of Midland Meres and Mosses Phase 2 Ramsar Site and would also act as a wildlife corridor for mammals. 2.1.4. Other components of the Proposed Scheme include the following:
Provision of a climbing lane on the westbound approach to the B4380 Holyhead Road Roundabout due to a 3% uphill gradient and approximately 10% heavy good vehicles (HGV) predicted for the Design Year 2038, and to help reduce queueing at the roundabout. The climbing lane would start east of B4380 Holyhead Road and the River Severn (tapering out from the 7.3m single carriageway width to 10.0m) and terminate at the proposed B4380 Holyhead Road Roundabout; Provision of accommodation works, including access tracks and gates, to enable landowner access to land severed by the Proposed Scheme; Provision of a combined footway and cycleway along the length of the Proposed Scheme. This would follow the alignment of the carriageway and hence would not be a bridleway due to the close proximity of the fast-moving traffic; Provision of a bridleway between Calcott Lane and B4380 Holyhead Road, which would link with the existing bridleway 0443/34A/2 to the east along Shelton Lane; Provision of two flood storage areas to mitigate for the loss of floodplain; Badger tunnels; Demolition works at West View, Holyhead Road (Shrewsbury, SY3 8BH); Landscaping, planting, and environmental mitigation to enable habitat improvements; and

4 GENERAL ENVIRONMENTAL REQUIREMENTS
4.1 REQUIREMENTS AND CONSENTS 4.1.1. The Proposed Scheme would be carried out within the requirements (but not limited to) of the relevant legislation (see Annex B). CONSENTS REGISTER 4.1.2. A register of planning, highways and environmental consents would be prepared and maintained by the Applicant and the Principal Contractor to keep track of any progress. This would enable the Project Team to plan for consents to be applied for and obtained prior to the relevant works activity commencing. 4.1.3. The progress of the preparation, submission and internal approval of the consents identified as being required would be tracked using the consents register. 4.1.4. This CEMP would be the overarching document outlining and tracking the delivery and achievement of legal compliance. AUDITS AND INSPECTIONS 4.1.5. Once construction work commences, internal environmental inspections and audits would be conducted on a regular basis. These would be carried out by the Environmental Advisor / Manager in accordance with the EMS to assess the environmental performance of the Proposed Scheme and to check compliance with the legal and contractual requirements. 4.1.6. Regular inspections of the construction areas would be carried out to verify housekeeping or supporting controls are being implemented effectively. Those inspections would utilise the site environmental standards as the minimum standards that would be achieved, with necessary corrective actions being recorded and raised via the appropriate channels. Subsequent inspections would commence with a review of all outstanding actions from previous reports to verify that they have been completed. 4.1.7. Environmental deliverables required by the CEMP would be subject to regular inspections by either the Environmental Advisor / Manager or the relevant environmental specialists. These inspections would be used to confirm that:
Construction works are progressing in accordance with the agreed method statements; Agreed protection or mitigation measures are in place, prior to or during the implementation of construction activities; and Construction works have been completed in accordance with the design and commitments made during the statutory process. 4.1.8. The Environmental Advisor / Manager would carry out an assessment of the Proposed Scheme’s environmental performance at a frequency at no greater than monthly internals but could be held more regularly depending on the nature of the construction activities. An assessment of the performance over the month would be made and quantified. 4.1.9. The associated report detailing performance for the period would be provided to the Applicant and the Principal Contractor and would include a summary of environmental inspections completed, audits undertaken, complaints and incidents.
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 9 of 70
4.2 OBJECTIVES AND TARGETS 4.2.1. The objective of this CEMP is to ensure that all those involved in the construction phase of the Proposed Scheme follow a specific framework which outlines all environmental impacts associated with the proposed construction woks. It also ensures that the environmental risks are properly identified and outlines the mitigation to be employed throughout the construction phase of the Proposed Scheme. 4.3 SITE COMPETENCE, TRAINING AND AWARENESS 4.3.1. The Principal Contractor should identify the training needs of their employees and sub-contractors so that they can implement the requirements of this CEMP into briefings and construction method statements. The Principal Contractor will create a competence, training and awareness tracker for all construction site operatives to ensure employees and sub-contractor training requirements and training given is recorded and monitored throughout the construction phase. 4.3.2. Specific training needs would be developed for individuals to reflect the work to be carried out on the Proposed Scheme and the significant risks and opportunities identified. 4.3.3. The requirement is for all personnel to be aware of their general environmental management responsibilities, and for those whose work may cause, or has the potential to cause, a significant impact on the environment, to receive specific environmental awareness briefings. Environmental awareness would be reinforced through information, such as poster campaigns, environmental/sustainability performance indicator reports and environmental alerts available on site noticeboards. 4.3.4. All contractors (Principal Contractor and Sub-Contractors) are responsible for ensuring the competency of their staff in relation to environmental matters. In the event that environmental training is needed for staff, a contractor is responsible for ensuring that this requirement is fulfilled. Any training provided to members of the Project Team would be logged and any certification documents would be produced by the relevant members of staff as evidence that they hold the required competencies. 4.3.5. All persons visiting and working on the Construction Site would receive an induction upon first arrival. The CEMP and other relevant management plans (e.g. SWMP, MMP, SMP) would be briefed to all during the induction. CONTRACTOR TRAINING 4.3.6. It is important to raise awareness of environmental issues so that all personnel on site are aware of what good environmental practice entails and where to obtain further information. Training will be provided on site to disseminate good practice guidance relevant to the Proposed Scheme. For a training programme to be successful and effective it is vital to:
Appoint a trainer with appropriate knowledge, skills and experience; Make training specific to the audience; Posting key environmental issues relating to the construction programme/phases on notice boards or in communal areas can keep awareness raised to all the workforce; Make training engaging and relevant; Follow up and refresh training to keep abreast of changes in legislation and codes of practice;

Use refresher training and inductions as a response to corrective actions raised (e.g. misuse of spill kits, incorrect refuelling methods); Check the understanding of the training with the attendees through tests, discussions, inspections and audits etc; and Maintain records of all training undertaken and planned. 4.3.7. This CEMP would form part of all tender documents circulated to all associated with the Proposed Scheme to ensure that the agreed principles are communicated. 4.3.8. Site specific inductions completed by the Site Manager for all staff and contractors new to the Proposed Scheme would include reference to the key sensitivities outlined in this CEMP. 4.3.9. The Site-specific induction would include training regarding the importance of the surrounding habitats, which would identify the required preventative steps the Site operatives are required to take to minimise the risk of damage to these habitats. Specific reference should be made to the adjacent water bodies as they are highly sensitive habitats. 4.4 INTERNAL COMMUNICATION 4.4.1. Communication on environmental issues within the Project Team would take place through face-to- face conversation, email and telephone. All staff on the Construction Site would be made aware of all environmental issues at the earliest possible opportunity. Communication on environmental matters would be maintained through regular meetings chaired by the Construction Site Manager. 4.4.2. Environmental issues identified by any member of the Construction Site Project Team would be entered into an environmental tracker, communicated to the relevant personnel to ensure any required actions are carried out, and closed out within an appropriate timeframe. Dissemination of information would take place in several forms as appropriate, including meetings to discuss particular project issues, method statements, task/activity briefings, toolbox talks, inductions, environmental notices and environmental alerts. Records that these have been carried out and who received them would be recorded on briefing registers and collated by the project administrator. The Environmental Advisor / Manager would provide updates to the supervisors to ensure policies and procedures on display are up to date. Supervisors would also be notified of any legislation changes which may affect working practices on the Construction Site. 4.4.3. Any unexpected finds/occurrences by site staff can be reported to their supervisors, who would then give notification to the Construction Site Manager who would advise on the course of action to be taken. 4.5 EXTERNAL COMMUNICATION COMMUNICATION WITH THE APPLICANT 4.5.1. The Principal Contractor would liaise regularly with the Applicant and their representatives regarding the programme of works, nature of the operations and the methods to be employed to reduce adverse environmental impacts. This would include progress meetings as well as the production and submission of progress reports which would cover environmental/sustainability issues. The Principal Contractor would also supply all relevant supporting information and documentation to the Applicant for matters concerning consents and the environment in accordance with the appropriate timescales.

COMMUNICATION WITH STATUTORY AND NON STATUTORY STAKEHOLDERS 4.5.2. The Principal Contractor would identify the requirement for liaison with statutory and non-statutory stakeholders and seek authorisation from the Applicant to undertake these. Where consultation is required, a representative from the Applicant would be invited to attend alongside the relevant Principal Contractor personnel. 4.5.3. Project staff would keep an archive of any e-mail correspondence between themselves, statutory and non-statutory stakeholders concerning the activities taking place. In the event that any complaints are received, a log of correspondence and complaints would be kept up to date by the Principal Contractor. 4.5.4. As a minimum, the Principal Contractor would be responsible for regular communication with the affected occupants and stakeholders including, but not limited to, those listed in Table 4-1.

PUBLIC RELATIONS 4.5.5. A minimum of 14 days prior notification by letter drop to those properties likely to be directly impacted before works are due to commence would be adhered to. The Principal Contractor would seek authorisation from the Applicant in advance of communicating with affected properties. The letter would outline where works are taking place, what activities are involved, timescales for the work and potential impacts and mitigation. 4.5.6. The process for distributing letters to the public is as follows:
Draft correspondence prepared by the Principal Contractor; Draft correspondence submitted to the Applicant for approval; Final correspondence returned to the Principal Contractor with appropriate distribution list; and Correspondence circulated to residents a minimum of 14 days prior to works commencing. 4.5.7. In addition, a Communication Plan would be developed by the Applicant and the Principal Contractor post-tender award and would be adhered to during the construction phase.

COMPLAINTS PROCEDURES 4.5.8. As part of the Construction Site set-up process, site notice boards would be erected, maintained and kept clearly visible to third parties. A contact telephone number for environmental complaints (as well as any comments and/or concerns) would be published local to the Construction Site. The Construction Site Manager would be responsible for dealing with any complaints and would have the appropriate authority to resolve any issues that may occur. Should they be required, an ‘out of hours’ telephone numbers would be available. 4.5.9. During any site work, if any complaints are received directly by the Principal Contractor or its sub- contractors, the Applicant and the Construction Site Manager would be notified as soon as is practicable but within twelve hours of the complaint being received. It would be the responsibility of the Construction Site Manager to investigate complaints in the first instance. Once the investigations have been concluded, the Construction Site Manager would ensure that the necessary corrective actions are implemented and monitored to ensure that they are appropriate. 4.5.10. The Environmental Advisor / Manager would maintain a close liaison with Shropshire Council’s Public Protection Officer at all times and should any complaints regarding environmental nuisance (e.g. dust or noise) be received by the Construction Site Manager, the details would be passed to the Public Protection Officer for verification purposes. 4.5.11. The formal procedure for handling project complaints / concerns would be developed by the Construction Site Manager and agreed with the Principal Contractor and Applicant but may include a procedure similar to that detailed below:
All stakeholders would be able to report any concerns, complaints or other comments to Principal Contractor in writing, by email or in person at the construction site offices. Site contacts details would be provided at the construction site entrances, on perimeter hoardings and possibly at appropriate community locations; The Principal Contractor would take full details of the concerns expressed and ensure that a formal assessment is commenced of the reported concern. They would also issue an initial response to the person who has submitted the complaint / concern confirming its receipt; The Construction Site Manager would record the date and contact information associated with a complaint / concern on a standard form and place a copy in a project complaints register; The Principal Contractor (or nominated representative) would undertake an investigation to assess what corrective and preventive action, or further investigation is necessary; The Principal Contractor (or nominated representative) would respond within a reasonable timescale (typically not more than 30 days) and place details of the completed corrective and preventive actions within the project complaints register. If a longer-term programme is required to provide an adequate solution, then this programme would be detailed on the complaints register against the specific issue; The Principal Contractor (or nominated representative) would notify the relevant stakeholder of the proposed corrective and preventive actions to be adopted; Any corrective measures / actions would be implemented with associated implementation dates being recorded; For long term corrective action, the complainant would be informed of the proposed action; and Following the implementation of the corrective action and agreement with the relevant stakeholder that the complaint has been adequately addressed the case would be closed and date recorded.

4.5.12. All complaints would be entered into the complaints register, each assigned an action, responsible person and close out date. The complaints register should be made available to Shropshire Council on request. 4.5.13. In the event that a complaint is not resolved to the satisfaction of the complainant directly with the Principal Contractor the following levels of mediation would be available:
If the grievance cannot be adequately addressed by the Principal Contractor, the complaint / concern would be escalated to an appropriate contact within the Applicant’s organisation; and If the grievance is still not adequately resolved the issue would be taken to Shropshire Council as the LPA for a final decision to be made. 4.6 RISK ASSESSMENTS 4.6.1. All construction activities would be subject to a risk assessment. Risk assessments would be undertaken by trained staff following an approved procedure which would:
Identify the significant environmental and Health & Safety impacts that can be anticipated; Assess the risks from these impacts; Identify the control measures to be taken and re-calculate the risk; Report where an inappropriate level of residual risk is identified so that action can be taken through re-scheduling of work or alternative methods of working in order to reduce the risk to an acceptable level; The results of risk assessments, and their residual risks are only considered acceptable if; the severity of outcome is reduced to the lowest practical level; the number of risk exposures are minimised; all reasonably practical mitigating measures have been taken and the residual risk rating is reduced to a minimum; and The findings of the risk assessment and the necessary controls would be explained to site operatives before the commencement of the relevant tasks using an agreed instruction format. 4.7 METHOD STATEMENTS 4.7.1. Method statements would be completed by the Principal Contractor or sub-contractor(s) by trained engineers or other appropriately experienced personnel, in consultation with on-site staff and, where necessary, environmental specialists. Their production would include a review of the environmental risks and commitments, so that appropriate control measures are developed and included within the construction process. 4.7.2. Method statements would be reviewed by the Environmental Advisor / Manager as well as the Principal Contractor and, where necessary, by the ECoW. Where required, method statements would also be submitted to the enforcement agencies for information (Environment Agency, Shropshire Council’s Public Protection Officer etc.). As a minimum, method statements would contain the following:
Location of the activity and access/egress arrangements; Work to be undertaken and methods of construction; Plant and materials to be used; Labour and supervision requirements; Health, safety and environmental considerations; and Any permit or consent requirements beyond those already obtained.

4.8 INCIDENT RESPONSE AND EMERGENCY PROCEDURES 4.8.1. An Incident Response Plan would be developed by the Principal Contractor to highlight the potential pollution receptors specific to each works area. Each document should be in place before construction activities commence and should be available for viewing and be briefed to the workforce on site. The documents would be reviewed and updated at least every six months. The key components of each Incident Response Plan would be as follows:
A brief scope of works taking place on site; Types of environmental incident that have the potential to occur (however low the risk); Types of hazardous material likely to be present on site; A list of pollution receptors and maps showing their location in relation to the site; The procedure for responding to environmental incidents, reporting them and investigation (including spill or leak events); Key contact numbers for reporting of environmental incidents; and Recommendations to help reduce the likelihood of environmental incidents. 4.8.2. The Principal Contractor would advise Shropshire Council within 24 hours of any incidents of non- compliance with the CEMP and would respond to any reported incidents within 24 hours, or as soon as reasonably practicable. In the event of working practices being deemed dangerous either by Shropshire Council or the Safety, Health and Environment Advisor, immediate remedial action would be taken. 4.8.3. The formal procedure for handling Environmental Incidents would be developed and agreed by the Principal Contractor and the Environment Manager but may include a procedure similar to that detailed below:
Environmental Incidents are to be reported to the Principal Contractor or Environment Manager; The Environment Manager would record full details of the Environmental Incident and ensure that they are responded to as soon as reasonably practicable (preferably within one hour but always within 24 hours); The Principal Contractor (or nominated representative i.e. Environment Manager) would monitor and ensure that appropriate action is taken; and The Principal Contractor (or nominated representative) would undertake an investigation to assess what corrective and preventive action, or further investigation is necessary to avoid recurrence of the Environmental Incident. 4.8.4. In the event of a spill or leak, the following process shown in Figure 4-1 would be followed. This would be briefed to the workforce and displayed on site notice boards. 4.8.5. All appropriate staff would be trained and made aware of the Incident Response set in place, following Environment Agency Pollution Prevention Guidelines 21 and 22 as best practice. In the event of any incident the Applicant would be notified. Additionally, the Environment Agency and any other interested bodies would be notified as required. 4.8.6. Procedures would also be set in place to respond to any emergency incidents which may occur on site. As the works progress the plan would be updated to reflect the construction stage.

5 CONSTRUCTION INFORMATION
5.1 CONSTRUCTION PROGRAMME AND PHASING 5.1.1. Construction work is currently targeted to commence in Spring 2022 and carried out until road opening in Autumn/Winter 2023. Full project completion is planned for Spring 2024. This construction programme is indicative and preliminary and would be revised and programmed in detail by the Principal Contractor. 5.1.2. An indicative construction programme is given below:
Site clearance (winter months leading up to Spring 2022; Establishment of accesses and compounds (months 1-3); Earthworks and cut and fill, drainage (months 1-19); Existing highway tie-ins (months 6-16); Structures (months 5-20); Offline surfacing (months 14-24); and Topsoiling, landscaping, fencing and signage (months 14-24). DEMOLITION PHASE 5.1.3. The implementation of the Proposed Scheme would result in the demolition of West View, Holyhead Road, Shrewsbury, Shropshire, SY3 8BH. This property is a two-storey brick-built house with pitched roof constructed in the 1900’s. Separated from the house is a double garage with pitched roof. The property has already been purchased by Shropshire Council the Applicant with services already disconnected and the premises boarded up and fenced off. It is anticipated that the property would be demolished ahead of the commencement of the main works for the Proposed Scheme. 5.1.4. The duration of the demolition works is unknown at the time of writing this report. It is estimated that approximately 320 tonnes of mixed construction waste would be produced. Where possible site arisings would be reused on site and/or recycled for use of other development schemes, but as a worst-case scenario it would be sent to landfill. PLANNED FUTURE WORKS 5.1.5. The Uplands Care Home and Severn Hospice has planning permission for the following works:
19/05426/OUT: Outline application (all matters reserved) for the erection of an extra care facility (C2 Use) to provide a maximum of 28 units. Proposed Residential Nursing Home, The Uplands, Clayton Way Bicton Heath Shrewsbury SY3 8GA 5.1.6. At the time of writing this CEMP the construction programme dates for this development are unknown. The Proposed Scheme is not expected to impact this future development, however full details would be passed onto the Principal Contractor to avoid any potential conflict and unnecessary disruption.
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 18 of 70
5.2 DIVERSIONS OF LOCAL ROADS, FOOTPATHS AND PUBLIC RIGHTS OF WAYS (PROWS) 5.2.1. The implementation of the Proposed Scheme is anticipated to result in the temporary and/or permanent diversion of some local roads, footpaths and PRoWs (Refer to General Arrangement Plans Sheets 1 to 32 and Plan and Longsections Sheets 1 to 7). 5.2.2. The permanent diversion of the following routes would be locally diverted to make use of the proposed highway (and combined footway and cycleway) and, where required, would cross the proposed highway by way of an overbridge or underpass. According to the current design, these include the following:
Calcott Lane would be severed by the Proposed Scheme. Therefore, ‘cul-de-sacs’ would be created and vehicular traffic would be able to access the northern section of Calcott Lane from the B4380 Holyhead Road and the southern section from the A458 Welshpool Road. A link between the south cul-de-sac and the combined footway and cycleway would be included, which would direct users to the Shepherd’s Lane Footbridge and link back to the north cul-de-sac by way of that route. Footpath 0408/7/1 runs from A458 Welshpool Road in a north-west direction to join Calcott Lane and would be intersected by the Proposed Scheme. Therefore, this footpath would link to the combined footway and cycleway and users would be diverted (along the southern side of the carriageway) to the safe crossing point (Shepherd’s Lane Footbridge) and via the diverted Footpath 0408/9/1 on the northern side. Footpath (0408/9/1) would be diverted along the northern field boundary to follow the direct desire line. A bridleway is proposed adjacent to this and would allow equestrian and cycleway connectivity between Calcott Lane and Shepherd’s Lane. Shepherd’s Lane would be severed by the Proposed Scheme where they intersect and as such would become a cul-de-sac on each side. Vehicular traffic would be able to access the northern section of Shepherd’s Lane from the B4380 Holyhead Road and the southern section from the A458 Welshpool Road. A direct connection would be made from the south section of Shepherd’s Lane for foot and cycle users and the provision of Shepherd’s Lane Footbridge would maintain foot and cycle access to the north section of Shepherd’s Lane. Little Oxon Lane would be severed by the Proposed Scheme where they intersect and would no longer be a vehicular route. Access to and from the Oxon Touring Park would be provided by way of the proposed Clayton Way Overbridge or for pedestrians and cyclists via the Shepherd’s Lane Footbridge. On the south side of the Proposed Scheme, Little Oxon Lane would be connected to the combined footway and cycleway. Footpaths 0443/46/1 and 0408/13/1: Footpath 0443/46/1 runs north from A458 Welshpool Road in a north-east direction to connect with Footpath 0408/13/1 which then runs in a north-east direction to join B4380 Holyhead Road. Footpath 0443/46/1 would remain as existing; however, footpath 0408/13/1 would be severed by the Proposed Scheme. Therefore, a link would be provided to the combined footway and cycleway on the south side, for pedestrians who would be diverted over Clayton Way Overbridge and link back into the existing footpath at the Oxon Hall Touring Park access. Clayton Way would remain open as access to the Oxon Hall Touring Park, Severn Hospice and Uplands Care Home but would be realigned onto a bridge over the Proposed Scheme. The bridge would also provide a safe crossing for pedestrians, cyclists and equestrians between the
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 19 of 70
north and the south sides of the Proposed Scheme and would connect with the combined footway and cycleway. A new bridleway route, outside the highway boundary fence and to the north of the Proposed Scheme, would be included for equestrians to link Clayton Way with B4380 Holyhead Road. B4380 Holyhead Road/Sustrans National Cycle Route 81: National Cycle Route 81 runs along B4380 Holyhead Road and connects Aberystwyth and Wolverhampton via Shrewsbury and Telford. The section of the National Cycle Route 81 along B4380 Holyhead Road is an ‘on road’ section of the route and would remain as such. However, cycleway and footway provision would be provided on all arms of the B4380 Holyhead Road Roundabout. Crossing points would be non-signalised via splitter islands with dropped kerbs and tactile paving. Cyclists travelling along B4380 Holyhead Road//Sustrans National Cycle Route 81 would be provided with on/off provision before and after the roundabout Bridleway 0408/14/4 and 0443/34A/2: a short section of Bridleway 0408/14/4 adjacent to B4380 Holyhead Road would be diverted to follow the existing track to the north-east of the roundabout. It would then pass through the proposed Equestrian Culvert East of Holyhead reconnecting with Bridleway 0443/34A/2 on the south side of the underpass (Shelton Lane). Footpath 0443/112/1: a short section, from a point north of the Proposed Scheme, would be diverted west to join the re-routed Bridleway 0408/14/4 and pass through he proposed Equestrian Culvert East Holyhead. The footpath would then follow the route of Bridleway 0443/34A/2. Footpath 0443/89/2 would be intersected by the Proposed Scheme and provision would be made for it to join the combined footway and cycleway. Where this footpath would intersect with the Proposed Scheme the footpath currently terminates and hence no diversion route would be required. Restricted By Way 0443/114/2 would be diverted through the formalised junction for the West Mid Showground. Footpath 0443/89/1 would be diverted along the existing Restricted By Way 0443/114/1 and would tie back into Footpath 0443/89/2 Footpath 0443/91/1 and 0443/92/1: Both footpaths would be diverted to follow the field boundary to the west of the Shrewsbury to Chester railway and would tie back into Footpath 0443/93/1 at the existing railway bridge. Access to the north of the Proposed Scheme would be facilitated via the Marches Way Accommodation Overbridge which would tie back into Footpath 0429/92A/1. Footpath 0443/94/1 would be intersected by the Proposed Scheme .This footway would be locally diverted to pass over the Proposed Scheme by way of the proposed Marches Way Accommodation Overbridge and return to its current route at the west end of the existing railway bridge. On the south side of the Proposed Scheme, a link would be added from this footpath to the combined footway and cycleway. North of the Proposed Scheme, the re-aligned Footpath 0443/104/1 (see below) would link with Footpath 0443/94/1 between the proposed Marches Way Accommodation Overbridge and the railway. Footpath 0443/93/1 Marches Way (west of the railway): To the south of the Proposed Scheme the existing route (as shown on maps) appears to have little use because an alternative route has been created by walkers/ramblers, closer to the railway. As such the path that is currently used would become the formal route, alongside the railway fence line. Both routes would re-align at the west end of the existing bridge over the railway, and approximately 600-700m south of this point. Footpath 0443/104/1 would be intersected by the Proposed Scheme. To the north the footpath would be re-routed, firstly, along the existing track (to remove the current ‘zig-zag’) in the field, and then west, alongside the highway boundary. The footpath would then pass over the
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 20 of 70
Shrewsbury to Chester railway, using the proposed Hencott Railway Bridge (by way of a footpath constructed on the north verge) and then the proposed Marches Way Accommodation Overbridge. The footpath would them link with Footpath 0443/94/1 (as referred to earlier). This footpath would then join with Footpath 0443/93/1 (Marches Way) on the south side of the Proposed Scheme, to link with the existing route to continue south or east, as it does already. The section of Footpath 0443/104/1, on the south side of the Proposed Scheme, would become a ‘cul-de-sac’ from Hencote Lane to the boundary of the Proposed Scheme. Footpath 0443/95/2: The existing footpath runs along Hencote Lane and ‘zigzags’ across the field to the north. As the direct desire line, this ‘zigzag’ section would be diverted along Hencote Lane. Footpath 0443/96/1 would be intersected by the Proposed Scheme. To avoid an unsafe crossing of the Proposed Scheme, the footpath would be diverted west from the junction of Crosshill Farm, joining Footpath 0443/95/2 along Hencote Lane and over Marches Way Accommodation Overbridge and join Footpath 0443/104/1 (see above). While it is not proposed to be encouraged, should users of the footpath wish to cross the highway and not follow the safe diversion, gates would be provided in the fence lines on both sides of the Proposed Scheme, in addition to steps to navigate the slope on the south side. Towards the northern end of the existing Footpath 0443/104/1, the route would make use of an existing permissive route to the south of Midland Meres and Mosses Phase 2 Ramsar Site’s boundary (created by walkers/ramblers) and would link back to the existing Footpath 0443/96/1. 5.2.3. All of the aforementioned local roads, footpaths and Public Rights of Ways (PRoWs) would require localised temporary diversions to facilitate the works and for the safety of the users. These diversions would be kept to as short a length as possible and, if any are required to be temporarily closed, for as short a time as possible. 5.3 CONSTRUCTION ACCESS / HAULAGE ROUTES, PARKING AND TRAFFIC 5.3.1. It is anticipated that construction traffic would be through the primary haul routes along the length of the construction site excluding the River Severn. There would be no access from any minor roads other than B4380 Holyhead Road, B5067 Berwick Road and A528 Ellesmere Road or through the surrounding towns and villages. 5.3.2. Any plant travelling to and from the construction site would use the SRN insofar as reasonably practicable. 5.3.3. During construction, the number of heavy good vehicles (HGV) and light good vehicles (LGV) movements would depend on the size and number of vehicles operated by the Principal Contractor once appointed on site. However, for the purposes of this ES, it is anticipated that the average daily two way movements of HGVs and LGVs would be 35 each. It is anticipated that the vehicle movements would be greatest, and potentially up to 180 each, during the importation of bulk materials to the construction site, the earthworks and the pavement works which are anticipated to last from four to six months. TRAFFIC AND HIGHWAYS 5.3.4. In agreement with Shropshire Council’s Highways Officer and Highways England as appropriate, signage directing vehicles to the site entrances will be installed. All site entrances will be clearly signed with adequate manoeuvring room.
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 21 of 70
5.3.5. The location of the signs is to be agreed prior to installation with Shropshire Council’s Highway Officer. The signs would be maintained throughout construction period. All construction traffic would be managed in accordance with the Construction Traffic Management Plan (CTMP) to be developed and implemented by the Principal Contractor. MAINTAINING ACCESS 5.3.6. During the construction of the Proposed Scheme there would be some disruption to the existing access arrangements within the local area. The Principal Contractor would be responsible for managing and co-ordinating this through ongoing communication with affected residents and local businesses. Approximately 100 land parcels would be affected across the Proposed Scheme to varying degrees by the associated owners and users of the accesses. 5.3.7. Exact proposals for the operation, phasing and sequencing of the works are yet to be determined, however this would need to remain flexible and adaptable throughout the works to accommodate changing needs and circumstances. The Principal Contractor must inform emergency services in advance of any diversion routes being put in place and land and property users would also be notified of the temporary arrangements. Users of Clayton Way And Little Oxon Lane 5.3.8. Specifically, there are three sites located to the north of the Proposed Scheme, that are accessed either via Clayton Way and/or Little Oxon Lane, which have expressed concerns regarding access arrangements during both the construction and operational phase of the Proposed Scheme. These sites are:
Severn Hospice; The Uplands Care Home; and Oxon Hall Touring Park. 5.3.9. The following sections outline the commitments from the Principal Contractor with relation to these facilities, the available access options at the time of writing this report and the indicative arrangements that would be further developed and agreed by the Principal Contractor once appointed. 5.3.10. The Principal Contractor would ensure that unfettered public and emergency vehicle access is maintained 24/7, 52 weeks a year to these sites despite any road closures that may need to take place. Outlined below are the options that have been studied and indicative arrangements that can be further developed and agreed by the Principal Contractor. Existing Access Arrangements 5.3.11. Existing access to these three sites is by means of side roads off A458 Welshpool Road (see Figure 5-1). The Severn Hospice and the Uplands Care Home are accessed via Clayton Way, and the Oxon Hall Touring park is accessed via Little Oxon Lane.

Figure 5-1 – Existing Access Arrangements
Permanent Access Arrangements 5.3.12. Clayton Way would remain open as access to the Oxon Hall Touring Park, Severn Hospice and Uplands Care Home but would be realigned onto a bridge over the Proposed Scheme. Little Oxon Lane would be severed by the Proposed Scheme where they intersect and would no longer be a vehicular route. Access to and from the Oxon Touring Park would be provided by way of the proposed Clayton Way Overbridge or for pedestrians and cyclists via the Shepherd’s Lane Footbridge. On the south side of the Proposed Scheme, Little Oxon Lane would be connected to the combined footway and cycleway (see Figure 5-2 and Figure 5-3).

Figure 5-3 – Proposed Permanent Access Arrangements
Temporary Access Arrangement Options 5.3.13. During the construction of the Proposed Scheme, there would be some disruption to access to these three sites. The Principal Contractor will be responsible for delivering a solution that allows temporary access to these sites during the construction phase of the Proposed Scheme which could be via Little Oxon Lane or a temporary access road. River User Access 5.3.14. Throughout the construction of the Proposed Scheme, the Principal Contractor would ensure that works within the area of the River Severn are managed and monitored effectively so that they do not unnecessarily impact river users. 5.3.15. It is envisaged that the river would remain navigable during large proportions of the works, however it should be acknowledged that at times, restrictions would be required during key operations for health and safety reasons. 5.3.16. The Principal Contractor would be responsible for ensuring advanced notice of timings and methodology to facilitate stakeholder communications. 5.3.17. Notably, one company operates canoe hire from Montford Bridge through to Shrewsbury Town Centre and would need to be consulted with throughout the construction works. Bus routes 5.3.18. The following ten bus stops and the roads on which they are located within the boundaries of the Construction Site are as follows:
Gains Park Way (bus stop: A458 Welshpool Road Junction) with bus services 74 and X75; A458 Welshpool Road (two adjacent bus stops: Heath Cottage) with bus services 70A, 74A and X75;

A458 Welshpool Road (bus stop: A458 Welshpool Road) with bus service 70A; Within Oxon Park and Ride (bus stop: Oxon Park and Ride) with unknown bus service number; A458 Welshpool Road (bus stop: A458 Welshpool Road, Adjacent Co-op) with bus services 70A, 74A and X75; A458 Welshpool Road (bus stop: Shelton Hospital) with bus services 74A and X75; A458 Welshpool Road (bus stop: Oxon Business Park) with bus services 70, 74A and X75; A458 Welshpool Road (bus stop: The Oxon Priory) with bus services 70, 74A and X75; The B4380 Holyhead Road (bus stop: The Oxon Priory) with bus service 70; and Knights Way (bus stop: Audi Garage) with bus service 501. 5.3.19. At the time of writing this CEMP, there is no intention to make any alterations to the existing bus routes. Bus operators looking to access sites north of Clayton Way would however, be required to use the diversions in place at the time, as described above. 5.4 CONSTRUCTION COMPOUNDS 5.4.1. The exact location of the compounds and the material storage areas is not available at the time of writing this CEMP and would be agreed once the Principal Contractor is appointed on site. However, for the purposes of the Environmental Statement, the main construction compound is located within the existing Oxon Park and Ride site as this will have been decommissioned by the time the construction of the Proposed Scheme starts. Two satellite compounds are also intended to be located to the north-west of the proposed B5067 Berwick Road Roundabout and to the north-east of the existing A528 Ellesmere Road Roundabout. A number of top soil storage areas and soil processing sites are intended to be located along the route of the Proposed Scheme. 5.4.2. The indicative location of the construction compounds and soil storage areas is shown in the Stripped Land Plan (Drawing Reference: 70056211-WSP-EBD-AS-SK-LE-00001). 5.4.3. All soil storage and compound areas would be secured and bunded during construction. Plant and equipment would also be stored in areas that are less susceptible to potential pollution incidents. Spill kits would be available for use in the event of an incident. 5.4.4. All materials would be offloaded and where possible distributed to the place where they are needed for incorporation into the permanent works. Materials would be stored in an appropriate environment with containers of liquid stored in a bunded area to prevent accidental spills. All material deliveries would be supervised by a responsible person. Any fuel deliveries would take precautions to ensure that the fuel storage tanks are checked before and during delivery to prevent overfilling. 5.4.5. The Construction Site Manager would make adequate provision to avoid accumulation of bulk materials on the construction site in order to prevent inconvenience or disruption and to eliminate the risk of fire, and dust. The Principal Contractor and Sub-Contractors would also ensure the construction site is left in a clean and tidy manner both during and outside working hours. 5.5 UTILITIES DIVERSIONS 5.5.1. The Proposed Scheme is anticipated to result in the permanent diversion of a number of overhead and underground utilities and/or the protection of existing services that are to remain in place. The locations and details of these diversions are listed in Table 5-1. 5.5.2. The exact location, including depth (by trial hole investigation) of many of the key components of the Proposed Scheme would determine the full extent of diversions required. Wherever possible,
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 25 of 70
temporary diversions would be avoided, but would be dependent on the permanent route being immediately available. 5.5.3. Discussions with a number of Statutory Undertakers have taken place and would continue during detailed design and construction in order to enable the timely diversion or extinguishment of services as appropriate. 5.5.4. The permanent diversion routes would also be determined by the relevant Statutory Undertakers especially where these might align with other planned works by them. It is envisaged that the relevant Statutory Undertakers would use their own Permitted Development rights under The Town and Country Planning (General Permitted Development) (England) Order 2015 to carry these works out. 5.5.5. The Principal Contractor would ensure that an uninterrupted supply of services is maintained to the Oxon Hall Touring Park, Severn Hospice and The Uplands Care Home. Precautions would be taken to identify and if necessary, protect existing services including British Telecom (BT), internet, water, gas, and electric during the works. The Principal Contractor would also provide an emergency plan developed in conjunction with the utility companies in the event of any planned or unexpected interruption to the existing services as a result of the works.

5.6 PRIVATE FARM SERVICES 5.6.1. Given that the Proposed Scheme goes through predominately arable farmland, there may be instances where private services would be impacted during the construction works. The Principal Contractor would ensure these services are maintained or a temporary equivalent provided; until the permanent solutions are in place. 5.7 WORKING HOURS AND RESTRICTIONS 5.7.1. The hours of working for normal construction activities would be from 07:00 to 19:00 Monday to Friday and 07:00 to 15:00 on Saturday. Construction operations outside of these hours will be by prior notification to the Planning Authority and will be for the following:
Nights: 22:00 to 06:00 for infrequent events, most likely towards the end of the construction phase to allow tie in surfacing between the Proposed Scheme and existing roads; and Rail interface works: Overnight works, with the agreement of Network Rail, which can only be undertaken either when the railway is not being used, or when the line is closed under a ‘possession’. 5.8 SITE SECURITY 5.8.1. Site security is an important component of good environmental management and the Principal Contractor will be responsible for the safety of the Site. Only authorised persons would be allowed on the construction site and a secure boundary would be established. The Principal Contractor
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 27 of 70
would inspect the boundary fencing weekly and, if damaged, would undertake repairs immediately. A record of these inspections and repairs would be kept. 5.8.2. Security would be controlled by physical locks and a signing in policy. It is also expected that CCTV would be installed at the construction site. No cameras would be capable of viewing neighbouring properties. 5.8.3. The Principal Contractor would maintain a 24-hour helpline during works. Signage would be provided on the hoardings to inform the public of the helpline number for reporting security incidents or concerns. The Principal Contractor would follow up security incidents and concerns reported and would arrange implementation of any further measures required. 5.8.4. The following security measures would also be considered by the Principal Contractor:
Do not stack materials against the inside or outside of the construction site boundary as this can provide an opportunity for unauthorised individuals to enter the construction site; Position fuel tanks, hazardous materials and waste away from the construction site boundary to deter theft and arson; Ensure that potentially hazardous materials are well secured and where possible located away from watercourses. For storage contains with a capacity in excess of 200 litres it is a legal requirement and also good practice, to lock fuel outlets when they are not in use, and provide secondary containment for oil in storage (e.g. bunds); Secure and immobilise plant and equipment overnight to prevent vandalism; Monitor the movement of people on and off the construction site using passes or swipe cards; Inform local police about the construction site and ask for their advice on security; Consult the Fire Service for advice on storing fuel and flammable materials on the construction site (where necessary); and If the construction site experiences a problem such as vandalism, ensure that appropriate measures are taken to clean up/repair and problems promptly, to discourage further problems from occurring. 5.9 CONSTRUCTION EMPLOYMENT 5.9.1. The exact numbers of construction workers are not known at the time of writing this report. It is anticipated that the construction of the Proposed Scheme would result in the creation of approximately 50 to 100 employment opportunities for the duration of the works. 5.10 SITE OFFICE AND WELFARE FACILITIES 5.10.1. It is anticipated that the main site office would be located within the main construction compound to be located at the Oxon Park and Ride site. 5.10.2. There would be a number of satellite welfare facilities around the construction site, particularly close to proposed structures. Indicatively, it is intended to locate welfare facilities:
North-east of A5 Churncote Roundabout; South-east of Clayton Way; West and east of the Shelton Rough River Severn Viaduct; and One on each side of the Hencott Railway Bridge. 5.10.3. The indicative location of the construction compounds and soil storage areas is shown in the Stripped Land Plan (Drawing Reference: 70056211-WSP-EBD-AS-SK-LE-00001).
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 28 of 70
5.10.4. Welfare facilities would be provided in accordance with Schedule 2 of the Construction (Design and Management) Regulations 2015. 5.11 TEMPORARY DRAINAGE SOLUTION 5.11.1. It is understood that as soon as topsoil is stripped and/or existing carriageways are altered, the permanent drainage system will be used in a temporary state to manage runoff 5.11.2. Runoff would be collected in containment areas in order that silts and any pollutants can be captured, and outlet flows can be controlled to agreed rates of discharge. For the works close to the River Severn, in particular, it may be necessary to apply to the Environment Agency (EA) for a discharge licence to ensure that any water discharge into the River Severn is within the limits set by the EA. 5.12 SITE CLEARANCE 5.12.1. The clearance of trees and hedgerows would be programmed to align with environmental restrictions, for example, bird nesting season. If appropriate, some cleared vegetation could be used for ecological features, such as hibernacula or refugia; other vegetation would be chipped or shredded but not burnt. Topsoil would be stripped in advance of earthwork excavations, so as not to mix the materials, with due consideration for any archaeological investigations that are to be undertaken in advance of the construction works. Existing street furniture would be dismantled and taken to the Highway Authority Depot for reuse/recycling where at all possible. Underground utilities would be first diverted before removing the redundant services. 5.13 EARTHWORKS AND SITE LEVELS 5.13.1. The earthworks within the Proposed Scheme would comprise both embankments and cuttings. The cut and fill balance is approximately 50,000m3 of soil to be imported to the site. The earthworks would be the first main works during the construction stage, once the haulage routes and construction compounds were established and the topsoil strip completed. 5.13.2. The cut and fill balance philosophy would be the main driver for the movement of earthworks. For example, it is planned that a volume of excavated material from one cutting would be transported across the construction site to form the fill to an embankment which would release the follow on phase of works (either structures or road construction). This would be done in order to maximise the material re-use and reduce the volume of material being removed off-site although some temporary stockpiling and screening/processing of material may be required. 5.13.3. The majority of the earthworks would be planned to take place between March and October inclusively. This is due to the uncertainty over the material type and suitability to excavate, haul and place over the winter and wetter periods. 5.14 CONSTRUCTION PLANT/EQUIPMENT 5.14.1. At this stage, the precise plant and equipment which may be used in the construction of the Proposed Scheme is not precisely determined as the Principal Contractor would set out detailed construction methods and plant/equipment requirements. In practice, the plant items identified would move around the site, operating at different times, durations and locations on any one day.
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 29 of 70
5.15 CRANES 5.15.1. All proposed structures would require the use of cranes. At this stage, the number of cranes used during construction is not precisely determined but it is anticipated that each structure would require at least a utility crane for a large proportion of the required construction time. In addition, there would be a number of larger cranes required for (e.g.) beam lifts and deck construction. 5.15.2. Smaller cranes would be required to install the precast concrete units for the proposed underpass and culverts. There would also be the need to employ concrete pumps for a number of the concrete pours at the structures, particularly to construct the decks. 5.16 CONSTRUCTION MATERIALS 5.16.1. For the purpose of the EIA, the typical material used in the construction of a scheme similar to the Proposed Scheme has been assumed to be as follows:
Earthworks and topsoil fill; Top soil; Hot rolled asphalt; Unhardened normal weight reinforced concrete; Hardened normal weight reinforced concrete; Aggregates i.e. capping and sub-base; Bitumen binders; Precast concrete kerbs; Dry stone wall; Normal fill; Structural backfill; Concrete (pre-cast concrete products only); Precast concrete box crushed stone (access track surfacing); Steel; Blinding concrete; Waterproof membrane or sprays; Fly ash (PFA); Timber and post rail fencing; Mortar for stonework; Safety barriers; Gates; and Seeding. 5.16.2. Topsoil would be stripped as a specific activity during the earthworks phase, and would be re-used on the Proposed Scheme on embankments and cutting slopes and verges. 5.17 DELIVERIES TO SITE 5.17.1. All sub-contractors and suppliers would be provided with clear instructions regarding deliveries to the Construction Site, unloading, storage and site distribution of materials. There would be clear signage for pedestrians to understand the delivery system as well.
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 30 of 70
5.17.2. All staff and supply chain personnel would comply with the Shropshire Council’s traffic management regulations and parking restrictions. This includes reversing back into spaces which is safer when leaving the parking space. 5.17.3. The Principal Contractor would manage deliveries to reduce daily truck movements to what is necessary. When there is a raised number of deliveries, for example a concrete pour, then the construction compound(s) would be used as a holding area. 5.17.4. All loading and offloading would be carried out within the boundary of the Construction Site. 5.17.5. Details of any requirements for abnormal or large loads (if required) would to be provided by the Principal Contractor in advance to Shropshire Council’s Highways Officer, and Highways England as appropriate, and routing and timings are to be agreed. 5.17.6. Any fuel deliveries would take precautions to ensure that the fuel storage tanks are checked before and during delivery to prevent overfilling. 5.17.7. In order to reduce the risks associated with construction traffic and deliveries, the following measures would be implemented:
Deliveries would be planned to happen outside of busy periods where feasible; Construction traffic would be directed via designated routes and under the direction of a banks man if the need for reversing is undertaken; Construction deliveries would be staged, if required. Initially this would be as directed by the banks man; Deliveries would be restricted to the Construction Site’s working hours to reduce disruption to local residents and businesses. Any deliveries outside working hours should be made in agreement with Shropshire Council; Plant operations and deliveries which are adjacent to areas such as pedestrian routes, non-site vehicular routes or work areas would be accompanied by a designated banks man at all times during its operation; The gate marshal would be required to direct pedestrians at access points to the Construction Site; and Any pedestrians visiting the Site office would be segregated from the vehicle movements by a dedicated fenced walkway. 5.18 MATERIAL STORAGE AND HANDLING 5.18.1. A Materials Management Plan (MMP) would be produced and implemented by the Principal Contractor in accordance with CL:AIRE for the generation, movement and storage of site won material. 5.18.2. Materials should be stored on site efficiently to reduce the risk of damage, environmental incidents, injury to site-based staff and theft. The following measures should be considered by the Principal when determining the storage of materials:
Materials should be stored at least 10m away from sensitive receptors and not within the flood plain; Material storage should be planned to avoid double handling; Ensure that any suppliers instructions are followed; Plan any storage areas so that frequently used items are easy to access;
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 31 of 70
Store valuable materials, or those that are hazardous or attractive to thieves, in a secure area, out of sight of the public; Store materials away from waste storage containers and from vehicle movements that could cause accidental damage; Materials should be covered to protect them against the elements; Secure any lightweight materials to protect them from wind damage or loss; and Take special care over the storage of materials that are potentially polluting. 5.18.3. The waste management area would contain separate waste stream skips, hazardous waste stations, and a recycling area for construction materials found within the waste, to be salvageable and usable. The records of the waste movements would be kept within the site office. 5.18.4. Material may be stockpiled on site within designated areas. It should be noted that excavated material should not be stockpiled for more than 12 months in accordance with The Environmental Permitting Regulations1. 5.18.5. A secure and bunded storage area would be located on site within the site compound(s) to contain and prevent the release of fuel, oils and chemicals associated with plant, refuelling and construction equipment into the water environment. This would be provided for the duration of the construction period. Secondary containment must be used with a capacity of no less than 110% of the container's storage capacity. 5.18.6. Plant and equipment would be stored in areas that are less susceptible to possible pollution incidents, or in dedicated areas of hard standing. A spill kit would be available for use in the event of an incident. 5.18.7. Any refuelling would take place away from any drains and would be adequately signposted to ensure the refuelling area is clearly visible to all. 5.18.8. Where possible, pre-cast and prefabricated elements would be delivered directly to their final position; thereby limiting the number of plant movements associated with double handling. All deliveries would be dealt with at the designated materials handling locations. 5.18.9. All sub-contractors would be required to produce the appropriate product data sheets and COSHH Assessment prior to using substances, which may be deemed hazardous to health. A copy of all COSHH Assessments would remain on site and may be required to form part of the Health and Safety File. 5.19 WHEEL WASHING FACILITIES 5.19.1. Details about wheel washing facilities are not available at the time of writing this outline CEMP. Wheel washing facilities would be installed on the Construction Site and remain for the duration of the construction period to reduce the spread of mud and debris onto the roads during excavations and material movements. All waste aggregates, water and sludge type materials resulting from the ‘cleaning’ process would be removed from the Construction Site by a licensed waste carrier and taken to a licensed waste disposal facility.

SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 32 of 70
5.19.2. Existing roads would be cleaned, as necessary, depending upon climatic conditions which would be monitored by the Construction Site Manager to ensure they are always kept clean. Monitoring of this would form part of the Principal Contractors’ Environmental Audits. 5.20 LIGHTING 5.20.1. Details about the lighting of the Construction Site are not available at the time of writing this outline CEMP. The extent of the area(s) to be lit would vary during the different stages of construction according to area of construction, security and health and safety requirements. There would be careful selection and planning of temporary lighting to reduce the potential effects of light pollution, including:
Identify sensitive receptors surrounding the Construction Site and position/direct lighting away from sensitive receptors so long as it doesn’t comprise health and safety; Use an appropriate powered light. The maximum considered to be suitable for exterior security lighting is 2000 lumens or 150 watts; Use appropriate levels of illumination; Install movement sensors with timers, as this would reduce the amount of time a certain area is constantly lit; Light areas only when and where required; Use the minimum amount of lighting, without compromising health and safety; and Install hoods, louvers, shields, reflectors and baffles to mitigate or reduce any light spillage. 5.20.2. An alternative to using traditional security lighting could be to install infrared security systems which would remove the need to light particular areas. 5.21 CONSTRUCTION WASTE 5.21.1. It is estimated there would be 10 waste collections required per week, travelling up to 25km to the expected treatment facilities by HGV during the construction of the Proposed Scheme. 5.21.2. Construction waste would primarily comprise class U12 arisings, which would require disposal. 5.21.3. Where at all possible (and as permitted by the specification and/or the Contractor) other construction materials would be recycled into the works or to another location. All the redundant signs, sign posts, and other street furniture would be recycled where possible. Construction waste that cannot be incorporated into the works would be segregated on site to assist with onward recycling. 5.21.4. Once a Principal Contractor is appointed, they would produce and implement a Site Waste Management Plan (SWMP). This would cover and enable the following:
Comply with duty of care regulatory requirements; Reduce the amount of waste generated in accordance with the Waste Hierarchy; Reduce waste sent to landfill and for combustion without energy recovery; and Maintain duty of care records. 5.21.5. The SWMP must be available on site at all times. All subcontractors must be made aware of the SWMP, its requirements and its location on site and it would be communicated at site induction.
2 Class U1 material is classified in two categories, Class U1A and Class U1B. This material excavated from within the site, unless processed to meet the necessary requirements shall not be used in the permanent works.
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 33 of 70
5.21.6. Wastes generated by the Proposed Development must be classified in accordance with the European Waste Catalogue (or List of Wastes). The six-digit waste codes that apply to wastes must be used on Waste Transfer Notes and Hazardous Waste Consignment Notes, as appropriate. 5.21.7. Some wastes may require chemical analysis testing to establish the correct waste code – this is particularly the case for soils, asphalt and other excavated materials. Chemical tests must be accompanied by interpretive reports giving the waste code, is appropriate. Waste Acceptance Criteria tests must not be used to classify waste; these tests are used to identify suitable landfill sites (inert or non-inert (non-hazardous or hazardous)). 5.22 KEY CONSTRUCTION PRACTICES 5.22.1. Construction works would be undertaken in accordance with the UK’s ‘Considerate Constructors Scheme’ to help ensure that contractors carry out their operations in a safe and considerate manner, and actively minimise environmental risks. In addition, all construction works would be undertaken with suitable temporary drainage and pollution prevention measures in place, in accordance with the Environment Agency’s Pollution Prevention Guidance Notes. 5.23 HEALTH AND SAFETY 5.23.1. This CEMP provides an overview of the measures and processes that are likely to be adopted during the construction phase of the Proposed Scheme. However, it is not intended to fulfil any legislative obligations of the Principal Contractor with regard to occupational health and safety. These obligations should be met within a standalone construction Health and Safety Plan. 5.23.2. Before works commence on site the Construction Site Manager is required to issue a Construction Phase Health and Safety Plan (CPHSP) to the Applicant. This would detail the initial health and safety procedures as works commence on site. The CPHSP would be regularly updated as the works progress and take into account all upcoming works. The specific content and requirements of the CPHSP plan would be briefed to all site staff during inductions. 5.23.3. The Principal Contractor would be required to audit safety on site monthly and provide a monthly report to the Applicant detailing numbers on site, accidents (if any), dangerous occurrences and any visits from the Health and Safety Executive (HSE) inspectors. 5.23.4. All works would be subject to approve risk assessments and method statements (RAMS). 5.23.5. Everyone employed on site would receive a Site-specific induction to inform them of the health and safety arrangements, welfare on site and to ensure they understand the requirements of the risk assessment and method statement relevant to their work. Workers would be informed of their legal obligation to comply with health and safety. The Construction Site Manager would be responsible for the health and safety of all visitors to the site at all times. 5.23.6. Barriers, platforms and hoardings would be erected, adapted and maintained throughout the construction phase to completely segregate the public from construction activity.

Receptors Description
Heritage Designated heritage assets assets The Grade II Berwick Park Registered Park and Garden is located immediately adjacent to the Application Boundary. The north-western most point of the Shrewsbury Conservation Area is located 320m to the south. Forty listed buildings are located within 1km of the Application Boundary, including 12 located within Berwick Park and four located within the Shrewsbury Conservation Area. Non-designated heritage assets There are several known non-designated features of heritage interest within the Application Boundary. These comprise undated cropmarks, which may indicate activity during the later prehistoric and Romano-British periods; a sub-rectangular enclosure of possible Iron Age to Romano-British date, east of B5067 Berwick Road; and ploughed out remains of medieval or post-medieval ridge and furrow have been identified at various locations across the Application Boundary. Ivy Cottage is a small road-side house located within the Application Boundary, which probably dates to the 19th Century.
Landscape Berwick Park, a Grade II listed registered park and garden is located to the north of the features Application Boundary and Alkmund Park Wood, an Ancient Replanted Woodland, is located immediately adjacent to the north of the Application Boundary. The Proposed Scheme lies wholly within National Character Area 61 – Shropshire, Cheshire and Staffordshire Plain.
Transport Existing receptors comprise users of the following: Network Local highways network including, but not limited to, A458 Welshpool Road, A5 Shrewsbury Southern Bypass, A528 Ellesmere Road, A5124 Battle Link Road, B4380 Holyhead Road, B5067 Berwick Road, Calcott Lane, Shepherd’s Lane, Shelton Lane, Gravel Hill Lane, Hencote Lane and Ellesmere Road Roundabout; Local bus services including, but not limited to, 70, 70A, 74, 74A, X75 and 501; Fiftteen Public Footpaths, two Public Bridleways, two Restricted Byways and 12 footways and one footway and cycleway within the Application Boundary.

SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 35 of 70
Receptors Description AQMA, in Bridgnorth, declared in 2005 referenced as Bridgnorth AQMA, lies approximately 30km south-east of the Application Boundary.
Geology and The Application Boundary predominantly comprises arable farmland, which has remained soils unchanged since earliest available historical mapping dated 1884. The superficial geology of the Application Boundary comprises Made Ground, Alluvium, River Terrace Deposits, Peat, Glaciofluvial Deposits, Glacial Till, Glacial Sand and Gravel (also referred to as the Basal Sand and Gravel), Kinnerton Sandstone Formation (formerly Bridgnorth Sandstone), Chester Formation and Wilmslow Sandstone Formation.
Agricultural Detailed surveys have shown that agricultural land quality to the west of the River Severn is land mostly affected by soil wetness and workability and is classified as mostly Subgrade 3a and Subgrade 3b. Land to the east of the river is mostly affected by soil droughtiness and limited variably to Grades 1 to 3b. The soil profiles include medium textured topsoils of sandy loam, sandy clay loam or medium clay loams. The topsoils are slightly stony. The upper subsoil textures are similar, with heavier textures of heavy clay loam and clay becoming more common as the profiles pass into lower subsoil horizons. In a localised area west of B5067 Berwick Road the subsoil becomes stonier and coarser textured with depth. There are eight agricultural land holdings within the Application Boundary, including but not limited to arable, dairy and beef farming.
Ecological The following statutory and non-statutory designated sites have been identified in the Designations ecological baseline: and Receptors Midland Meres and Mosses Phase 2 Ramsar – Hencott Pool – The Meres and Mosses such as 18 component sites comprise nutrient-rich open water bodies (meres) with a range of fauna and fringing habitats. These are features which have developed in depressions made by flora receding glacial drift; Hencott Pool SSSI (also designated as a Ramsar Site); Old River Bed, Shrewsbury SSSI – a cut-off meander of the River Severn, this site is of particular value for its extensive sedge fen; Seven ancient woodland sites have been identified within 2km of Application Boundary, including Alkmund Park Wood, and three ancient woodland sites more than 2km of Application Boundary, but within 200m of the Affected Road Network; Seven Local Wildlife Sites within 2km of Application Boundary; Five Local Wildlife Sites greater than 2km of Application Boundary, but within 200m of the Affected Road Network (i.e. the road network that will experience a notable change in flow as a result of the Proposed Scheme); and One Local Nature Reserve (Rea Brooke Valley) beyond 2km from the Application Boundary but on the Affected Road Network. A total of 27 different habitats were recorded within the Application Boundary across all surveys, including the following habitats likely to meet the criteria as Habitats of Principal Importance (HPI).

Receptors Description
The main species identified within the Application Boundary and the surrounding area are as follows: Amphibians including great crested newt (GCN) Triturus cristatus and common toad Bufo bufo; Aquatic macroinvertebrates; Fish; Macrophytes; Badger Meles meles; Bats (foraging and roosting, all species); Wintering and breeding birds (all species); Riparian mammals: otter (Lutra lutra) and water vole (Arvicola amphibius); Reptiles including grass snake (Natrix Helvetica) and adder (Vipera berus) Terrestrial invertebrates; Invasive plant species listed on schedule 9 of the WCA, 1981, Himalayan balsam.
Water The Proposed Scheme would cross the River Severn, which is a main river, and would Environment cross or require diversion of four ordinary watercourses Calcott Lane Ditch, Oxon Ditch, Alkmund Park Stream, Hencott Stream. Furthermore, the middle pond of Willow Pool, which consist of three ponds separated by farm access tracks would be crossed by the Proposed scheme. Other main rivers and watercourses within 1km of the Application Boundary, but not crossed by the Proposed Scheme include: Unnamed ordinary watercourse (located towards the western boundary of the Proposed Scheme approximately chainage 300m); Ordinary watercourse, Bicton Brook; Unnamed drain (south of the Proposed Scheme approximately chainage 1350m); Ordinary watercourse, Bagley Brook West; Ordinary watercourse, Battlefield Brook; Bowbrook (or Rad Brook; main river); and Unnamed stream, herein referred to as Udlington Drain (approximately 780m upstream of the proposed Shelton Rough River Severn Viaduct, just south of Berwick House). Fifteen other surface water features are located within 1km of the Application Boundary. The most notable of these are: Oxon Pool Country Wildlife Site, Midland Meres Phase 2 Ramsar Site and Hencott Pool SSSI, Old River Bed SSSI, Old Riverbed Bed Local Wildlife Site, two smaller ponds within the Oxon Ditch catchment and immediately adjacent to the Proposed Scheme, and other small ponds that have no known designations. A surface water abstraction point, managed by Severn Trent Water Limited (STWL), located at Shelton Rough approximately 100m upstream of the proposed Shelton Rough River Severn Viaduct. This abstracts water from the River Severn and supplies a significant component of the potable water for Shrewsbury. STWL have a licence to abstract up to 14.1million m3 a year or 38,641 m3 a day. Because of this abstraction and other nearby groundwater abstraction boreholes, the Study Area is classed as a Drinking Water Protected Area. It is not classed as a Nitrate Vulnerable Zone. There are six other surface water abstractions up to 5km downstream of the Proposed Scheme, which are directly hydrologically connected to the Proposed Scheme. The Application Boundary between chainage 0m and 2350m lies within Source Protection Zones (SPZ) Zone 1 to Zone 3. The abstractions are drawing from the Kinnerton Sandstone Formation (Principal Aquifer) which forms part of the Triassic Sherwood Sandstone Aquifer system. The source of local groundwater recharge to the superficial deposits is predominantly from rainfall. Due to the low permeability of soil and superficial deposits, groundwater recharge in the area is considered relatively low, and run-off and evaporation
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 37 of 70
Receptors Description relatively high. The Kinnerton Sandstone Formation is an extensive Principal Aquifer that receives recharge from multiple sources within the wider catchment. The Proposed Scheme transects two difference Groundwater Management Units (GMU) within the above groundwater body including the Alberbury GMU and Merrington GMU. The Proposed Scheme crosses Flood Zone 2 and Flood Zone 3 of the River Severn, furthermore Flood Zone 2 and 3 have also been identified in the vicinity of Alkmund Park Stream crossing. There are pockets of high, medium and low flood risk from surface water throughout the Study Area and within the Application Boundary. There has been no historical recorded incidents of groundwater flooding from groundwater sources in the Shropshire Strategic Flood Risk Assessment (SFRA).
Noise and The study area includes the following sensitive receptor types: dwellings; schools; Vibration churches; hospitals and other medical facilities; and ecologically designated areas. Existing manmade noise and vibration sources in the Proposed Scheme area have been identified as: dominated by road traffic noise, including the A5 Shrewsbury Southern Bypass, A458 Welshpool Road, A528 Ellesmere Road and other local roads; secondary sources being more localised railway noise and some limited aircraft noise. There are no Noise Important Areas within 1km of the Application Boundary, with the closest approximately 1.5km from the Application Boundary.
Local The closest local communities to the Application Boundary include Calcott, Bicton, Bicton communities, Heath, Bowbrook, Shelton, Berwick, Rosehill, Coton Hill, Mount Pleasant and Battlefield. community Ten open spaces located within the 1km study area. and private land Oxon Pool and Pool Wood, and Waincott Park/Playground is located directly adjacent to the Application Boundary. One private property which is located off the B4380 Holyhead Road is located within the Application Boundary.
Arboriculture The following arboricultural features were identified within the Application Boundary and the surrounding area: 114 high-quality features – comprising of 110 individual trees and four wooded areas, including Alkmund Park Wood; 126 moderate-quality features; 164 low-quality features; and One very-low quality feature.

6.2 POTENTIAL ENVIRONMENTAL IMPACTS 6.2.1. A schedule of potential construction phase environmental impacts that may require management is provided in Table 6-2.
Table 6-2 – Potential Environmental Impacts
Topic Potential Environmental Impacts
Air Quality Dust and particulate matter (PM) emissions from on-site related construction activities including the following: Annoyance / loss of amenity due to dust soiling; Risk to health and safety due to an increase in PM exposure; and Impacts to ecological receptors.
Agriculture and Soil Loss of best and most versatile agricultural land; Resources Restoration of land used temporarily for construction to agriculture; and Loss and severance of land from farm holdings.
Arboriculture Removal of arboricultural features directly located within the footprint of the proposed carriageway, pavements, earthworks, drainage features, sightlines, haul roads, site compounds and areas of temporary and permanent land strip. Impacts associated with the construction of the carriageway, pavements, drainage features and highway fencing within the root protection areas of trees which may otherwise be retained. Impacts associated with the stripping of land within the root protection areas of trees which may otherwise be retained. Impacts associated with construction activities (i.e. access and storage) within the root protection areas of trees which may otherwise be retained.
Biodiversity Loss of small areas of woodland, hedgerows and trees; and of continuous scrub, to accommodate construction, is of moderate severity and is significant, notably given that the wider landscape is largely intensively managed arable land. Disturbance to bankside habitats near the River Severn, and siltation and run- off during viaduct works. Siltation and run-off during viaduct works, minor scale but significant, leading to damage to habitats and direct harm from pollutants entering the watercourse including chemicals, sediment and oils. Significant disturbance through light, noise and vibration, leading to avoidance behaviour in fish. Accidental pollution from construction drainage for ponds, including any macroinvertebrates within them would be of negligible scale and not significant. Significant temporary vegetation clearance around the existing pond at Chainage 450m near the A5 Churncote Roundabout; and in wet woodland at Alkmund Park Wood, the latter affecting a medium metapopulation of GCN. Potential disturbance of badgers arising from construction noise, vibration, traffic and human activity, and from vegetation clearance for construction. Construction noise, vibration and lighting has the potential to disturb bats if they are roosting in trees during 2022 and 2023; and lighting may disrupt foraging activities. Vegetation clearance for construction only is not a significant loss of habitat for bats, but some of the operational planting required for permanent loss would be included pre-construction to ensure that the temporary loss is further minimised, and to allow time for the operational mitigation planting to establish in some

Topic Potential Environmental Impacts
cases. Some areas would also be retained to ensure continuity of habitat through the period of construction. Demolition of West View would be a minor and significant loss of an occasional summer roost. Construction noise, vibration, traffic and activities would result in significant disturbance of otters using the River Severn near the viaduct works in particular. Construction noise, lighting and activity would present a significant disturbance to breeding birds in habitats adjacent to construction, storage and compound areas. Temporary vegetation clearance includes some of the wet woodland corridor south of Alkmund Park Wood; of moderate severity and significant for terrestrial invertebrates. Significant risk of accidental spread of Himalayan balsam. Damage to the root protection areas (RPA) of trees.
Climate Change The impacts of Greenhouse Gas (GHG) emissions relate to their contribution to global warming and climate change. These impacts are global and cumulative in nature, with every tonne of GHGs contributing to impacts on natural and human systems. GHG emissions result in the same global effects wherever and whenever they occur. Risks associated with climate and weather-related changes (Climate Resilience) during the construction period phase include the following: Increasingly difficult working conditions caused by extreme rainfall, high temperature events or storm events, including time available to undertake works, which may result in delays; Increased precipitation resulting in the potential of flooding of the site, overwhelming of drains, excessive moisture in materials and destabilisation of materials; and High temperature events leading to deformation and melting of materials, Shorter drying times of materials in summer and the potential for overheating of machinery.
Potential congestion, pedestrian facilities and bus services changes during Equality construction. Potential reduced air quality and increased noise levels during construction. Change on road and footpaths layout.
Geology and Soils Impacts on best and most versatile agricultural land within the construction site. Sterilisation of sand and gravel as a mineral resource. Soil erosion from earthworks leading to sediment loading of nearby surface water bodies. Soil compaction and de-vegetation as a result of increased hardstanding cover leading to reduction in infiltration and increase in surface water run-off. The introduction of contaminative materials such as inappropriate storage and use of fuels, cement grouts, etc which may impact on soils and water resources. Impact to human health of current site users, neighbouring land users and construction works from potential contaminants via direct contact, ingestion and inhalation and wind-blown dust. Impact to groundwater and potable abstraction points through the construction of piles creating a preferential pathway for contamination and increased turbidity, leading to indirect impact of public water supply.

Topic Potential Environmental Impacts
Historic Environment Potential for the partial or complete loss of buried heritage assets. Light spillage at B5067 Berwick Road Roundabout into the setting of Berwick Park Grade II Registered Park and Garden and the Grade II listed Gravelhill.
Landscape and Removal of existing landscape features including mature hedgerows and trees; Visual Increased visibility from the loss of screening vegetation; Earth forming; Temporary stockpiles of soil; Construction traffic and plant activity; Site compound and material stockpiles visible; and Views of cranes during the construction of the Shelton Rough River Severn Viaduct.
Materials and Waste Direct impacts: Consumption of natural and non-renewable resources; and Generation and disposal of waste and reduction of landfill capacity. Indirect impacts: Release of greenhouse gas emissions; Water consumption scarcity; Nuisance to communities (visual, noise and health); Generation and disposal of waste; and Public health issues.
Noise and Vibration Noise arising from construction works; Increase in noise levels associated with increased traffic as a result of the construction vehicles; and Increase in vibration effects, during construction (vibratory compaction/piling etc).
Population and Temporary and permanent requirement of land from private properties and Health housing allocations. Temporary severance between communities and community land and assets. Temporary loss of land for development and businesses and potential a temporary impact on business viability. Temporary and permanent loss of land from agricultural land holdings; and the temporary and permanent severance of agricultural land holdings. Temporary and permanent changes in journey length and route diversion for PRoW and other WCH routes. Impact on human health resulting from potential increases in noise and reduced air quality (due to dust) associated with construction activities. Construction employment opportunities may also have temporary impacts on human health outcomes through improved mental and physical health and opportunities for social contact. Changes to driver stress due to likely increases in drivers’ frustration, fear and uncertainty due to the traffic management measures and road diversions or closures implemented during construction. Changes to drivers view on the existing road network. Changes in journey amenity due to the reduced amenity along WCH routes which are located in proximity to the construction works, where increased visual intrusion is anticipated.

7 ENVIRONMENTAL CONTROL MEASURES
7.1 ENVIRONMENTAL PROCEDURES 7.1.1. The Principal Contractor would ensure that all sub-contractors adhere to the relevant local policies and good practice guidelines for implementation during all Site activities. 7.1.2. In order to avoid/mitigate against any significant environmental effects, a series of indicative Project Environmental Procedures (PEPs) have been proposed. 7.1.3. Responsibilities for the implementation of each PEP has been assigned to specific members of the project team, which it is envisaged would comprise:
Principal Contractor (site based); Health, Safety and Environment Manager (site based); and Environmental Consultant (air quality, ecology and noise specialists for example). 7.1.4. A list of the indicative PEPs is provided in Table 7-1. Further details relating to each PEP are contained within Annex C of this CEMP.

7.2 AIR QUALITY 7.2.1. In line with the best practice to be implemented at the Site, IAQM guidelines, and in order to manage the nuisance and impact arising from dust produced during the construction phase, the following measures are to be implemented: GENERAL COMMUNICATION
A Stakeholder Communications Plan that includes community engagement before construction work commences on Site would be developed by the Applicant in collaboration with the Principal Contractor and implemented.
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 43 of 70
The name and contact details of person(s) accountable for air quality and dust management issues would be displayed on the construction site boundary. This may be the Environment Manager/Engineer or the Site Manager. The head or regional office contact information would also be displayed. GENERAL DUST MANAGEMENT
A Dust Management Plan (DMP), which may include measures to control other emissions, in
addition to the dust and PM10 mitigation measures given in this report, would be developed and implemented by the Principal Contractor, and approved by Shropshire Council’s Public Protection Officer. SITE MANAGEMENT
All dust and air quality complaints would be recorded and causes identified. Appropriate remedial action would be taken in a timely manner with a record kept of actions taken including of any additional measures put in-place to avoid reoccurrence. The complaints log would be made available to the SC’s Public Protection Officer on request. Any exceptional incidents that cause dust and/or air emissions, either on- or offsite would be recorded, and then the action taken to resolve the situation recorded in the log book. Regular liaison meetings with other high-risk construction sites within 500m of the Application Boundary would be held, to ensure plans are coordinated and dust and particulate matter emissions are minimised. It is important to understand the interactions of the off-site transport/deliveries which might be using the same strategic road network routes. MONITORING
Daily on-site and off-site inspections would be undertaken during dust generating activities, where receptors (including roads) are nearby to assess dust. The inspection results would be recorded and made available to the Local Authority on request. This would include regular dust soiling checks of surfaces such as street furniture, cars and windowsills within 100m of the Application Boundary, with cleaning to be provided if necessary. Regular site inspections to monitor compliance with the DMP would be carried out, inspection results recorded, and an inspection log made available to SC’s Public Protection Officer on request. The frequency of site inspections would be increased when activities with a high potential to produce dust are being carried out and during prolonged dry or windy conditions.
Dust deposition, dust flux, or real-time PM10 continuous monitoring locations would be agreed with the SC’s Public Protection Officer. Where possible baseline monitoring would start at least three months before work commences on the construction site or, if it is a large site, before work on a phase commences. PREPARING AND MAINTAINING THE SITE
Plan the construction site layout so that machinery and dust causing activities are located away from receptors, as far as is practicable. Where practicable, erect solid screens or barriers around dusty activities or the Application Boundary that are at least as high as any stockpiles on the construction site. Where practicable, fully enclose the construction site or specific operations where there is a high potential for dust production and the site is active for an extensive period.
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 44 of 70
Avoid site runoff of water or mud. Keep site fencing, barriers and scaffolding clean using wet methods. Remove materials that have a potential to produce dust from the construction site as soon as possible, unless being re-used on site. If they are being re-used on-site cover appropriately. Where practicable, cover, seed or fence stockpiles to prevent wind whipping. OPERATING VEHICLE/MACHINERY AND SUSTAINABLE TRAVEL
Ensure all vehicle operators switch off engines when stationary; no idling vehicles. Avoid the use of diesel- or petrol-powered generators and use mains electricity or battery powered equipment where practicable. A maximum-speed-limit of 15 mph on surfaced and 10 mph on unsurfaced haul roads and work areas would be imposed. If long haul routes are required these speeds may be increased with suitable additional control measures provided, subject to the approval of the nominated undertaker and with the agreement of SC’s Public Protection Officer, where appropriate. A Construction Logistics Plan would be produced by the Principal to manage the sustainable delivery of goods and materials. A Travel Plan that supports and encourages sustainable travel (public transport, cycling, walking, and car-sharing) would be considered. OPERATIONS
Only use cutting, grinding or sawing equipment fitted or in conjunction with suitable dust suppression techniques such as water sprays or local extraction, e.g. suitable local exhaust ventilation systems. Ensure an adequate water supply on the construction site for effective dust/particulate matter suppression/mitigation, using non-potable water where possible and appropriate. Use enclosed chutes and conveyors and covered skips. Minimise drop heights from conveyors, loading shovels, hoppers and other loading or handling equipment and use fine water sprays on such equipment wherever appropriate. Ensure equipment is readily available on the construction site to clean any dry spillages and clean up spillages as soon as reasonably practicable after the event using wet cleaning methods. WASTE MANAGEMENT
Avoid bonfires and burning of waste materials. MEASURES SPECIFIC TO DEMOLITION
Soft strip inside buildings before demolition (retaining walls and windows in the rest of the building where possible, to provide a screen against dust). Ensure effective water suppression is used during demolition operations. Handheld sprays are more effective than hoses attached to equipment as the water can be directed to where it is needed. In addition, high volume water suppression systems, manually controlled, can produce fine water droplets that effectively bring the dust particles to the ground. Avoid explosive blasting, using appropriate manual or mechanical alternatives. Bag and remove any biological debris or damp down such material before demolition.
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 45 of 70
MEASURES SPECIFIC TO EARTHWORKS
Re-vegetate earthworks and exposed areas/soil stockpiles to stabilise surfaces as soon as practicable. Use Hessian, mulches or tackifiers where it is not possible to re-vegetate or cover with topsoil, as soon as practicable. Where practicable, only remove the cover in small areas during work and not all at once. Stockpile surface areas would be minimised (subject to health and safety and visual constraints regarding slope gradients and visual intrusion) to reduce area of surfaces exposed to wind pick- up. Where practicable, windbreak netting/screening would be positioned around material stockpiles and vehicle loading/unloading areas, as well as exposed excavation and material handling operations, to provide a physical barrier between the Application Boundary and the surroundings. Where practicable, stockpiles of soils and materials would be located as far as possible from sensitive properties, taking account of the prevailing wind direction. During dry or windy weather, material stockpiles and exposed surfaces would be dampened down using a water spray to minimise the potential for wind pick-up. MEASURES SPECIFIC TO CONSTRUCTION
Reduce scabbling (roughening of concrete surfaces) where feasible. Ensure sand and other aggregates are stored in bunded areas and are not allowed to dry out, unless this is required for a particular process, in which case ensure that appropriate additional control measures are in place. Ensure bulk cement and other fine powder materials are delivered in enclosed tankers and stored in silos with suitable emission control systems to prevent escape of material and overfilling during delivery. For smaller supplies of fine powder materials ensure bags are sealed after use and stored appropriately to prevent dust. All construction plant and equipment would be maintained in good working order and not left running when not in use. MEASURES SPECIFIC TO TRACKOUT
Use water-assisted dust sweeper(s) on the access and local roads, to remove, as necessary, any material tracked out of the Application Boundary. This may require the sweeper being in frequent use. Avoid dry sweeping of large areas. Ensure vehicles entering and leaving the Application Boundary are covered to prevent escape of materials during transport. Inspect on-site haul routes for integrity and instigate necessary repairs to the surface as soon as reasonably practicable. Record all inspections of haul routes and any subsequent action in a site log book. Where practicable, hard surfaced haul routes would be installed, which would be regularly damped down with fixed or mobile sprinkler systems, or mobile water bowsers and regularly cleaned. Implement a wheel washing system (with rumble grids to dislodge accumulated dust and mud prior to leaving the Application Boundary where reasonably practicable).
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 46 of 70
Ensure there is an adequate area of hard surfaced road between the wheel wash facility and the Application Boundary exit, wherever Application Boundary size and layout permits. Access gates to be located at least 10m from sensitive receptors where possible. 7.2.2. Detailed mitigation measures to control construction traffic would be agreed between the Principal Contractor and Shropshire Council to establish the most suitable access and haul routes for the construction site traffic. The most effective mitigation would be achieved by ensuring that construction traffic does not pass along sensitive roads (residential roads, congested roads, via unsuitable junctions, etc.) where possible, and by ensuring that vehicles are kept clean (through the use of wheel washers, etc.) and sheeted when on public highways. Timing of large-scale vehicle movements to avoid peak hours on the local road network would also be beneficial. 7.2.3. Particulate monitoring would also be undertaken during the construction phase of the Proposed Scheme. A methodology monitoring would be agreed with SC’s Public Protection Officers through the CEMP process as part of the discharge of planning conditions. 7.3 AGRICULTURE AND SOIL RESOURCES 7.3.1. There are no universally applicable measures available to mitigate the direct loss of agricultural land. 7.3.2. The primary measures to mitigate the effects on soil resources would be set out in a Soil Resource and Management Plan that would need to be developed during the pre-construction phase and implemented by the Principal Contractor. The plan would confirm the different soil types based on the soil survey already undertaken (refer to Appendix 7.1 of Chapter 7: Agriculture and Soil Resources); the most appropriate re-use for the different types of soils within the design of the Proposed Scheme; and the proposed methods for handling, storing and replacing soils on-site. 7.3.3. The quality of soils retained on-site and exported off-site (if required) would be maintained by following good practice guidance on soil handling and storage, in accordance with Defra’s Code of Construction Practice for the Sustainable Use of Soils on Construction Sites. In particular, it would be necessary to avoid compaction and biodegradation of soils that are to be retained on site in storage. In this respect, topsoil must be stockpiled separately to subsoil. 7.3.4. With the adoption of appropriate mitigation for soil handling and restoration, the soils would be able to continue their various ecosystem functions, principally as a medium for producing food and biomass; for storing and cycling water and carbon; and for supporting habitats; biodiversity and landscape planting. 7.4 ARBORICULTURE PROTECTION OF RETAINED ARBORICULTURAL FEATURES Arboricultural Method Statement 7.4.1. The Arboricultural Method Statement (AMS) included in Annex C of Appendix 8.20: Arboricultural Impact Assessment has adopted a precautionary approach to tree protection and has addressed those activities which have the potential to cause damage to retained trees. Arboricultural features which are to be retained and protected are identified Figure 3: Arboricultural Protection Plan included in Annex I of Appendix 8.20: Arboricultural Impact Assessment. Areas within the Application Boundary where protection measures should be applied are referenced as Construction
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 47 of 70
Exclusion Zones (CEZ). These are the areas within which any construction activities should have due regard for the physical and biological requirements of retained features. 7.4.2. For the purposes of the Proposed Scheme these should reasonably include all activities within the CEZ of any retained arboricultural feature and include:
Arboricultural monitoring; Removal of arboricultural features; Access facilitation pruning; Protective barriers; Land stripping; Earthworks; Pavement construction; Highway drainage; Highway fencing; Carriageway removal; Soft-landscaping activities and, Badger sett construction. 7.4.3. The AMS included in Appendix 8.20: Arboricultural Impact Assessment includes reference to the above activities where sufficient design information exists for a design and construction methodology to be identified. It is envisaged that the AMS would increase in scope and detail once more information becomes available during detailed design. 7.5 LANDSCAPE AND VISUAL 7.5.1. The Landscape Design Plans (Drawing Reference: 70056211-WSP-ELS-R1-DR-LE-30001 to 70056211-WSP-ELS-R1-DR-LE-30032) make provision for the planting of a wide range of arboricultural features including woodland, linear belts of trees and shrubs, scattered trees, individual trees and native hedgerows. 7.5.2. Included within these proposals are the establishment of 16 individual trees. These trees have been specified as compensation for the loss of veteran trees and have been designed to ensure that:
They are of the same species as the veteran trees which are being removed; They are planted in sustainable locations; They are as near as possible to the location of the veteran trees which are being removed and/or the location of retained ancient, veteran or notable trees; and, They are within areas where the intact hulk of removed veteran and other large diameter trees can be placed to benefit habitat creation. 7.5.3. Trees planted to compensate for the removal of veteran trees cannot mitigate their loss nor would they reduce the associated adverse effects. They would however increase the likelihood of future veteran tree formation. 7.5.4. It is envisaged that the Landscape Design Plans would be developed during detailed design and would include particular reference to the development of a strategy which compensates for the loss of veteran trees. This should include:
The development of a detailed planting specification for replacement trees; The development of a long-term maintenance plan for replacement trees;

Further inspections of retained ancient, veteran and notable trees with recommendations for landscaping measures to improve their rooting environment, habitat potential and general health; Further inspections of trees within Alkmund Park Wood with recommendations for landscaping measures to improve their rooting environment, habitat potential and general health; and, The development of a monitoring programme for retained ancient, veteran and notable trees such that management operations can be varied or implemented where these would benefit their long-term health and viability. 7.6 BIODIVERSITY HABITATS: WOODLAND, TREES, SCRUB, HEDGEROWS AND GRASSLAND 7.6.1. Landscape planting, some of which is required to mitigate operation phase impacts, but which would also mitigate temporary loss of habitats due to construction. Of note for construction impacts are:
Woodland, shrub, hedgerow, grassland and wildflower planting as presented on the Landscape Drawings (70056211-WSP-ELS-R1-DR-LE-30001 to 70056211-WSP-ELS-R1-DR-LE-30032) Shrub planting along the species rich grassland to the west of Calcott Lane. Grassland and woodland/scrub at Chainage 350m is to be planted pre-construction, around the GCN pond that is included in the design at this location. Woodland and grassland would be planted around the attenuation basins at Chainages 410m and 4300m. Scrub and fruit trees to be planted pre-construction, to accommodate the replacement badger sett, would also replace some of the scrub and trees temporarily lost under the scheme footprint. 7.6.2. Planting to ensure habitat connectivity would be required for bats, but would also mitigate temporary loss of scrub and woodland habitats. 7.6.3. Pre-construction Phase 1 habitat survey of the Severn Viaduct flood storage area, as a survey of this area was not possible due to access arrangements. This survey should confirm the findings of the aerial imagery-based assessment that has been carried out to inform this assessment. Where the field survey indicates the need for additional protected species surveys, these would then be required to be carried out, and any relevant licensing or updates to the assessment would be required prior to construction. HABITATS: RUNNING AND STANDING WATER
Vegetation clearance along banks would be minimised and reinstated. Where feasible, discharges would not be direct to any watercourse, but would be made to ground (where appropriate). However, little opportunity is likely to be available for this approach. Therefore, for the most part, sediment laden water generated on site would be appropriately treated before discharge. This may be using silt fences, silt traps, filter bunds (possibly straw bales or gravel bunds), settlement ponds and/or proprietary units such as a ‘siltbuster’. Local weather forecasts would be monitored and works scheduled accordingly. Earthworks and in-stream works may be stopped, or otherwise adequately controlled, during storm events. Emergency response plans would be developed, and spill kits made available on site. Construction compounds and stockpiling areas would be located at least 50m from sensitive watercourses. Fuels and potentially hazardous construction materials would be stored in bunded areas with external cut-off drainage; fuel would be stored in double skinned tanks with 110% capacity.

Construction plant would be checked regularly for oil and fuel leaks, particularly when construction works are undertaken in or near the existing site waterbodies. Waste fuels and other fluid contaminants would be collected in leak-proof containers prior to removal from site to an approved processing facility. Washing out of any cement or concrete lorries would be carried out off site. PONDS
Measures outlined for management of road drainage and the water environment in construction, as described under running water and standing water above, would mitigate any accidental pollution of ponds. AQUATIC INVERTEBRATES
Measures outlined for management of road drainage and the water environment in construction, as described under running water and standing water above, would mitigate any accidental pollution of the River Severn (and other watercourses). FISH
Measures outlined for management of road drainage and the water environment in construction, as described under running water and standing water above, would mitigate any accidental pollution of the River Severn (and other watercourses). Low impact piling methods should be used where possible. A soft start to piling operations should be used whereby low impact noise is generated before impulsive noise to deter fish from the immediate area. Break periods in piling activity should be implemented to allow fish to pass through areas affected by underwater noise. AQUATIC MACROPHYTES
Measures outlined for management of road drainage and the water environment in construction, as described under running water and standing water above, would mitigate any accidental pollution of the River Severn (and other watercourses). AMPHIBIANS: GREAT CRESTED NEWTS
Shrub planting along the species rich grassland to the west of Calcott Lane would be required for operational impacts, but also would mitigate for loss of the terrestrial GCN habitats due to construction in this area. Grassland and woodland/scrub at Chainage 350 is to be planted pre-construction, around the GCN pond that is included in the design at this location. Planting for the Proposed Scheme that aims to ensure habitat connectivity at would also mitigate for construction-related loss of terrestrial habitats for amphibians in the Alkmund Park Wood area. Brooklime and water mint would also be included in pond planting for attenuation basins and any amphibian/GCN ponds, such as the proposed GCN pond at Chainage 350m. Measures outlined for management of road drainage and the water environment in construction, as described under running water and standing water above, would mitigate any accidental pollution of ponds

MAMMALS: BADGER 7.6.4. A zone of 30m and 50m around individual sett entrances, including the sett that would replace MS1, should be clearly demarcated during construction in which no construction works are permitted. Any works required within these exclusion zones should be discussed with the ECoW prior to works, to ensure necessary mitigation and/or licensing is in place. The ECoW would carry out pre-works surveys of all setts to confirm their status prior to commencing of works, allowing sufficient time to apply for and obtain any licences to disturb badgers if these are required once the sett statuses are re-confirmed. Where possible this should be fenced (for example with Netlon or similar highly visible material), with fencing clearly labelled to avoid the risk of re-alignment or removal of fencing (fencing should be at least 180mm above ground level to enable badgers to pass beneath). All construction activities within 30m of a sett should be avoided during the breeding season (i.e. they should be completed between July and November inclusive); and pile driving, or other high vibration activities should be avoided within 100m of a sett (though specific consideration should be given to each situation as described above). Unavoidable vegetation removal within 30m of a sett should be completed sensitively using hand tools (to include chainsaws and brushcutters) rather than tracked machinery. 7.6.5. A replacement sett would be constructed in land north of the footprint of the Proposed Scheme. The new sett location is confidential and would be along an existing foraging rote for badgers. Tie-in works for a proposed access track would also be completed in 2021 as these works would be within 30m of the replacement sett. This would be completed prior to the closure of the Holyhead Sett in 2021. 7.6.6. A license to close the existing Holyhead sett would be sought in 2021, avoiding the period December 2021 to June 2022. Use of fencing and one-way gates to exclude badgers form the existing sett, along with monitoring and food provision at the new sett. This would be carried out pre- construction. Any new badger setts which are found in 2021 during pre-construction checks may also require a licence. 7.6.7. Planting to help funnel badgers towards crossing points at culverts and the Equestrian Underpass, along with planting of fruit trees and suitable habitat around the proposed replacement sett, would reduce the effects of habitat loss on badgers to negligible levels. MAMMALS: BATS 7.6.8. Construction noise within 30m of any identified roosts identified in pre-construction surveys should be supervised by an ECoW and techniques such as soft start working, avoiding leaving machinery or vehicles running when idling, and limiting works around dusk and dawn where they are within 30m of a confirmed roost, would mitigate for these effects. Hoods, louvres and cowls should be used to direct site lighting away from roost features and from foraging routes. 7.6.9. Pre construction emergence/re-entry surveys would be required at the buildings at Ivy Cottage prior to construction to ensure that any licensing is based on up to date information. Preferably, access for emergence/re-entry would be gained the summer prior to construction to ensure that up to date pre-construction data are gathered to inform the need for any licensing of works within 30m of Ivy Cottage. 7.6.10. Foraging and commuting routes for bats would be monitored during construction, to confirm the need for any additional mitigation measures such as the use of artificial hedgerows or controls of
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 51 of 70
lighting, hours of working or other measures required to mitigate disturbance to bats. This would include repeating Local and Landscape scale bat surveys in as described in Appendix 8.10 on one occasion during the construction phase. 7.6.11. Along with pre-construction bat surveys in 2021, a bat licence would need to be sought from Natural England for the demolition of West View, and any new bat roosts found during the pre-construction surveys would also require a licence from Natural England prior to any works commencing. 7.6.12. Bat boxes would be provided to replace the roost at West View; these should be sited and installed under the supervision of a suitably qualified ecologist prior to demolition. 7.6.13. Planting for the Proposed Scheme also includes the below elements that would, once established post-construction, mitigate for some of the temporary construction-related losses. Temporary artificial hedgerows would also be used to maintain some continuity of habitat where feasible during the construction process:
Woodland planting at Chainages 200m to 240m would be included to maintain a dark corridor for bats using this area. Pre-construction planting at Clayton Way (as far as feasible), use of temporary artificial hedgerows at crossing points, and retention of dark commuting corridors for bats would reduce the effects of lighting and noise, but there would still be a significant residual effect as most of the hop-over planting for bats would not be established until after construction. Woodland edge mix with scattered trees for a bat hop-over at Chainages 3500m to 3900m, tied in to an existing hedgerow which would be retained. Woodland and scrub with fruit trees to accommodate the replacement badger sett for MS1 would provide continuity of habitat for bats during construction. Planting of woodland, scrub and unmanaged grassland immediately west of Alkmund Park Wood would provide for habitat connectivity at the crossing point identified here. Replacement trees and woodland planting would be required for bats to use the area around the planned crossing at Alkmund Park Wood to minimise the loss of habitats from the construction process. RIPARIAN MAMMALS: OTTER
Pre-construction checks for signs of otter, including confirmation or otherwise of the presence of any holts or couches, would be carried out prior to construction. These checks would inform the need for any derogation licensing required for the works; at present no signs of otter have been observed on within the Application Boundary. Soft start techniques would be used where practicable, and vehicles and machinery would be switched off when not in use. In addition, hoods, louvres and cowls to direct site lighting away from sensitive areas would be used. Works during the hours of darkness would be kept to a minimum near the River Severn. Although risks of injury and mortality to otters is negligible, any excavations would be safely fenced off at night, with boards placed to allow any mammals, including otters, to safely egress should they fall in. Site staff would all be made aware of the potential for otters to be present on within the Application Boundary. BREEDING BIRDS 7.6.14. Timing of vegetation clearance would aim to avoid the bird nesting season (March – August inclusive), however where it not possible, pre-construction checks for breeding birds should be
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 52 of 70
carried out not more than 48 hours prior to any work beginning. Active nests would be monitored by a suitably qualified ECoW and left undisturbed until no longer in use by breeding birds and their young. Soft start techniques would be used where practicable, and vehicles and machinery would be switched off when not in use. In addition, hoods, louvres and cowls to direct site lighting away from sensitive areas would be used. TERRESTRIAL INVERTEBRATES
Wet woodland habitats are retained as far as practicable during construction. Planting for the Proposed Scheme would also mitigate for the temporary losses of these terrestrial invertebrate habitats, with planting of woodland and grassland habitats near the attenuation basin at Chainage 4300m, hedgerow and scrub planted at Chainages 440m to 4600m; and scattered trees at Chainages 4500m to 4520m near the wingwalls for the proposed culvert at Alkmund Park Wood. INVASIVE SPECIES 7.6.15. Working areas should be surveyed for signs of Himalayan balsam and other invasive species prior to construction, to map their extent and to inform a suitable plan for avoiding accidental spread. Where works areas would overlap with areas of Himalayan balsam, cutting of the plant between March and May prior to construction, ensuring that stems are cut below the lowest plant node, and before they flower, would help to avoid accidental spread. If space allows, cut materials should be covered with an impermeable membrane to compost. Soil that has contained Himalayan balsam would not be re-used. If this is not possible, any arisings would be disposed of at a suitably licensed waste treatment facility. 7.7 CLIMATE CHANGE GREENHOUSE GASES 7.7.1. The following mitigation measures to minimise greenhouse gas emissions are to be implemented:
Site won materials (earthworks, topsoil) would, where possible, be re-used to reduce the quantity of imported earthworks and resultant impacts associated with extraction and transport of material. 7.7.2. Other best practice construction methods that are expected to reduce emissions where implemented include:
Design optimisation to reflect the carbon reduction hierarchy (detailed below and found in clause 6.1.4 of BSI (2016) Publicly Available Specifications:2080 Carbon management in Infrastructure): Reduce the elements required for the Proposed Scheme; Reduce the requirement for construction materials; Substitute construction materials for lower-carbon alternatives; and Use efficient construction processes, such as design for manufacture and assembly.
Adoption of vehicles with best-in-class efficiency for construction, and delivery. Adoption of efficient logistics management for transport of construction materials and excavated material.
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 53 of 70
Minimise energy consumption including fuel usage by, for example, minimising plant use, idling and specifying efficient plant (or hybrid or electric plant). Maximise the local sourcing of materials and the use of local waste management facilities; Adoption of plant and processes with best-in-class efficiency for construction. Designing, specifying and constructing the Proposed Scheme with a view to maximising the operational lifespan of design elements and therefore minimising the need for maintenance and replacement (and all associated emissions). Designing, specifying and constructing the Proposed Scheme with a view to maximising the potential for reuse and recycling of materials/elements at the end-of-life stage. Designing, specifying and constructing the Proposed Scheme with a view to minimising maintenance requirements. CLIMATE RESILIENCE 7.7.3. The measures identified in Table 7-2 ensure the construction process is resilient to the changes in climate identified in Chapter 9: Climate Change of the ES. The measures have been used to inform the assessment of effects as presented in Chapter 9.

7.8 EQUALITY 7.8.1. The following mitigation measures would be adopted by the Principal Contractor to mitigate potential impact on equality protected characteristics during construction, including age, disability and gender.
Consultation with Earlyworld Nursery, Shrewsbury Prepatoria Nursery and Pre-School, Tiddlywinks Nursery and Dog A.I.D. should be undertaken and measures should be in place to minimise impact to their pupils and users during construction. Further consideration should be given during detailed design to identify measures which may be required to mitigate potential reduced air quality (at The Coppice, Marches Care/The Uplands and Severn Hospice (Hospice Bicton) and increased noise levels (at The Uplands) during construction along the Proposed Scheme between Clayton Way Overbridge and B4380 Holyhead Road Roundabout. Further consultation with care homes and the Royal Shrewsbury Hospital should be undertaken to understand if any specific issues and remedial actions are required regarding potential impacts on people with dementia during construction and operation. Careful consideration on sign posting at footway junctions, safety and design of footpaths and greenspaces should be considered during the detailed design stage. Earlyworld Nursery, Shrewsbury Prepatoria Nursery and Pre-School, Tiddlywinks Nursery and Dog A.I.D. are potential sensitive receptors during construction, where attention should be given by the Principal Contractor when developing the Traffic Management Plan. A Communications
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 56 of 70
Plan should be developed by the Principal Contractor in collaboration with the Applicant and be implemented to enable closures or diversions of any routes or bus services be communicated directly to these facilities. Air quality and noise monitoring should be undertaken at The Coppice, Marches Care/The Uplands and Severn Hospice (Hospice Bicton) during construction (see Sections 7.2 Air Quality, 7.13 Noise and Vibration of this CEMP). A Communication Plan should be developed by the Principal Contractor in collaboration with the Applicant, and be implemented to enable any commencement of noise generation activities to be communicated directly to these facilities. Emergency services should be consulted with when the Principal Contractor is developing the traffic management plan, especially if temporary works have the potential to interfere with access, including the Royal Shrewsbury Hospital Accident and Emergency department and healthcare facilities which provide palliative care or services for people with dementia. 7.9 GEOLOGY AND SOILS DECOMMISSIONING BOREHOLES 7.9.1. The Interim Borehole Decommissioning Plan (provided in Appendix 10.4 of Chapter 10: Geology and Soils) details the methodology and borehole locations which require decommissioning prior to construction works commencing in the area. The plan also provides detail on the borehole locations requiring protection (for continued monitoring purposes during and post construction). 7.9.2. These works are required in order to prevent the boreholes being a preferential pathway for potential contaminants being introduced at the surface. MONITORING ACTIVITIES 7.9.3. The Interim Baseline Water Quality and Construction Monitoring Strategy (provided in Appendix 10.5 of Chapter 10: Geology and Soils) details the surface water and groundwater monitoring required across the Proposed Scheme. It would include baseline (pre-construction), during and post construction monitoring works. It includes details on locations, frequency of monitoring and sampling, the laboratory testing required and trigger values / thresholds for specific determinands. If concentrations exceed these trigger values, these would be reported to Shropshire Council and Environment Agency within 48 hours of receipt of the results and further advice obtained from the Environmental Manager/Advisor. 7.9.4. The Interim Piling Works Risk Assessment (provided in Appendix 10.3 of Chapter 10: Geology and Soils) details requirements on turbidity monitoring. This utilises sensor technology to complete continuous monitoring (30 minute recording frequency), including the collection of pre-piling baseline groundwater turbidity data, during the piling works and post-piling works to demonstrate there is no long-term impact to the underlying aquifer from piling activities. It includes turbidity trigger values and proposed actions, if exceeded. 7.9.5. It should be noted that non-asbestos fibres were identified by the chemical testing laboratory at some locations (refer to Appendix 10.1: Interim Baseline Contamination Study Report of Chapter 10: Geology and Soils). Whilst this has not been identified as asbestos, further sampling and testing may be prudent to try and identify the material, assess potential risks and confirm whether remedial actions are necessary.
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 57 of 70
MATERIALS MANAGEMENT 7.9.6. Details on materials management and waste is provided in Sections 5.18 and 5.21 with some brief measures outlined below:
Construction compounds and stockpiling areas would be located at least 50m from sensitive watercourses. All topsoil and subsoil would be handled and stored carefully to minimise the potential for damage to the soil structure. A detailed method statement would be produced by the Principal Contractor clearly identifying correct stripping, soil handling, storage, and placement and programming requirements to avoid compaction and moving the material in unsuitable weather conditions. The Earthworks Series 600 Specification must be followed. This includes the frequency and testing requirements for the importation of material or reuse of site won material. A Definition of Waste Code of Practice (DoW CoP) Materials Management Plan should be in prepared, approved by a Qualified Person (QP) and uploaded onto the Contaminated Land: Applications in the Real Environment (CL:aire) website, for use on site for the reuse of site won materials. PREVENTATIVE MEASURES 7.9.7. All construction related refuelling activities should be undertaken on hard standing in dedicated re- fuelling areas. 7.9.8. There is also a potential risk that the Principal Contractor could import unsuitable fill or landscaping soils to the site which could pose a risk to human health and the environment. This can be mitigated through appropriate clauses in the Contract Specification document including testing of imported materials. 7.9.9. A watching brief would be maintained during earthworks activity to ensure that unexpected contaminated materials if encountered are managed in an appropriate manner and in accordance with statutory requirements. 7.9.10. There is potential for impact to human health including current and neighbouring site users, and construction works from potential contaminants via direct contact, ingestion and inhalation. 7.9.11. It is the responsibility of the Principal Contractor to assess the related risks and implement controls and procedures to ensure this risk is minimised, including following best practice procedures such as workers wearing appropriate Personal Protective Equipment (PPE), good hygiene practices, and ensuring appropriate dust suppression techniques and vehicle washing carried out. 7.9.12. Potential construction phase environmental impacts have been identified relating to hydrogeology and hydrology. These mechanisms are as follows:
Direct and indirect contamination of surface water due to mobilisation of soils, existing contamination and spillage of oils and the like from construction plant. Direct and indirect flooding and changes to baseline drainage hydrology due to disturbance of the ground during construction works. 7.9.13. The discharge of suspended solids to watercourses and groundwater would be avoided by prohibiting any temporary construction discharge without the prior approval of the Environment
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 58 of 70
Agency. Discharges of waters resulting from construction activities would generally be directed to foul sewers, subject to approval of the drainage authority. 7.9.14. There is the potential for fuel oil spillage from stored materials supplying site plant, this potential impact would be controlled by storing such materials within bunded tanks. The works would be completed in a manner that is consistent with the need to protect the soils, and the water resources. 7.9.15. There is potential for piling operations to create a preferential pathway for contamination and increased turbidity, leading to indirect impact of the public water supply. 7.9.16. It would be incumbent on the Principal Contractor to assess working practice related risks and effects before implementation and control such by employing industry good practice techniques. Furthermore, the Principal Contractor would be required to develop emergency spillage, flood, fire and contamination control procedures such that any inadvertent incidents are immediately controlled to minimise the potential impact. All works would be completed in accordance with the up to date government regulatory requirements including guidance from Environment Agency documents, PPG 6 Working at Construction and Demolition Sites and PPG21 Pollution Incident Response Planning together with current best practice measures for the management of construction activities. 7.9.17. The Principal Contractor would not be permitted to temporarily store materials or introduce ‘borrow pits’ or the like in areas that may affect drainage flow paths. 7.9.18. All fuels, oils, chemicals, etc. would be stored in appropriate containers in accordance with good site practice and the above-mentioned documents. This would mitigate the potential for spills. 7.9.19. Oil absorbent booms would be installed, as appropriate, on the surface watercourses immediately downstream of the works area and would be regularly inspected and maintained. Spill kits should be in the work area ready for use if required and emergency procedures in place should an incident occur. 7.9.20. The Environmental Advisor/Manager would be responsible for disseminating good practice to the construction team and for checking the Contractors’ initial plans and that the work is being carried out in accordance with them. 7.10 HISTORIC ENVIRONMENT ARCHAEOLOGICAL REMAINS 7.10.1. Further archaeological evaluation is proposed which would include a further phase of geophysical survey as well as trial trenching. The results of the evaluation would enable the formulation of an appropriate mitigation strategy for any significant archaeological assets (e.g. design changes/avoidance and/or targeted excavation and/or 'strip, map and sample'). Alternatively, the preliminary investigations may indicate that no further work is necessary in certain areas. 7.10.2. The scope of archaeological mitigation would depend upon the results of the evaluation stage, and the nature, significance and survival of archaeological remains. For heritage features of high or very high (national) significance, where feasible these could be preserved in situ, i.e. through modifications to the design (e.g. foundations and formation levels or avoidance) or preservation by record (archaeological excavation and recording). For other remains, mitigation could take the form of a targeted excavation (preservation by record) well in advance of the commencement of ground works across all areas where disturbance is proposed. Alternately a programme of 'strip, map and record' could be employed alongside the preliminary construction works (site strip) to ensure all
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 59 of 70
potential archaeological remains were not removed without record. This would need to be programmed with adequate time for the recording of archaeological features. This would ensure that any archaeological assets were not removed without record prior to construction works. 7.10.3. The scope of further archaeological evaluation and any subsequent mitigation required by the results of the evaluation would be agreed with the Shropshire Council Historic Environment Team. ABOVE GROUND HERITAGE ASSETS 7.10.4. The lighting of the Construction Site would be designed in order to avoid light spillage on Berwick Park Grade II Registered Park and Garden and the Grade II listed Gravelhill. 7.11 LANDSCAPE AND VISUAL 7.11.1. Measures to avoid and/or reduce potential impacts during construction would include the following:
Avoiding the loss of existing vegetation where possible, with removal to be limited to the minimum required, such as only clear felling trees/woodland within the site extents if required to enable works. Retained trees and woodland would be protected by barriers and/or ground protection in accordance with BS 5837:2012 (Trees in relation to design, demolition and construction – Recommendations) before any materials or machinery are brought onto the site, and before any demolition, development or stripping of soil commences. Construction compounds to incorporate hoarding of minimum height 2.5m to screen views of materials and plant. 7.11.2. Measures to manage soils on site would be in accordance with the Construction Code of Practice for the Sustainable Use of Soils on Construction Sites and would include the following:
Undertaking a soil resource survey on site by a suitably qualified and experienced soil scientist or practitioner prior to any earthworks operation and incorporate the results of this into the site working strategy. Prepare a Soil Resource and Management Plan showing the areas and types of topsoil and subsoil to be stripped, haul routes, the methods to be used, and the location, type and management of each soil stockpile. When stripping, stockpiling or placing soil, do so in the driest condition possible and use tracked equipment where possible to reduce compaction. Follow appropriate soil stockpiling methods according to whether they are ‘dry non-plastic’ or ‘wet plastic’ soils. To avoid damage to soils, confine traffic movement to designated routes. Keep soil storage periods as short as possible. Clearly define stockpiles of different soil materials. If stockpiling soil for more than six months, the surface of the stockpiles should be seeded with a grass/clover mix. 7.11.3. The mitigation measures described above are not exhaustive. Landscape and visual mitigation should be reviewed and discussed with key stakeholders and the Principal Contractor to help inform the identification and agreement of further measures required during construction.

7.12 MATERIALS AND WASTE 7.12.1. The management of materials and waste in accordance with best practice principles, to achieve a circular economy, is a central tenet of sustainable development. The key principles that underpin this ethic are:
A change in mindset where action is taken to ‘increase resource productivity’ rather than simply ‘manage waste’; Application of the Waste Hierarchy, as set out by the Waste Framework Directive (2008/98/EC), which outlines and details the action to reduce the production and disposal of waste, and to recover materials, arisings and waste so that they are redeployed at the end of each service life Application of the Proximity Principle, which highlights the need to manage, treat and/or dispose of wastes as close as practicable to their point of generation. 7.12.2. These principles lay the foundation for the following requirements for managing materials and waste during construction of the Proposed Scheme. LEGAL REQUIREMENTS 7.12.3. The Principal Contractor would comply with legislation regarding Materials and Waste (provided in Annex B) with particular attention drawn to the following regulations:
The Waste (England and Wales) Regulations: These regulations require businesses to confirm that they have applied the waste management hierarchy when transferring waste and include a declaration to this effect on their waste transfer note or consignment note. Hazardous Waste (England and Wales) Regulations: These regulations introduce measures to control the storage, transport and disposal of hazardous waste. It provides a means to ensure that hazardous waste and any associated risks are appropriately managed. Environmental Permitting (England and Wales) Regulations 2016: These regulations dictate the licencing of persons or businesses involved in the management of waste. They also relate directly to the licencing of a site or activity (including exemption) to carry out the management, processing and disposal of wastes. COMPLIANCE WITH SUSTAINABILITY PRINCIPLES 7.12.4. The Principal Contractor would manage and facilitate the separations of wastes and materials, ready for potential diversion from landfill in accordance with the Waste Hierarchy (Figure 7-1). The principles of which are Prevention, Preparing for reuse, Recycling, Recovery, and Disposal.
Figure 7-1 - The Waste Hierarchy
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 61 of 70
7.12.5. The Principal Contractor would provide evidence that management of waste and materials has been in line with the Proximity Principle. That is, the management, treatment and/or disposal of wastes in reasonable proximity to their point of generation. REQUIRED CONSTRUCTION MITIGATION MEASURES 7.12.6. The Proposed Scheme should achieve the regional aggregate recycled content of 27%, or at least the England Average of 25%. Therefore, the Principal Contractor would identify opportunities to include materials (aggregate) with recycled content subject to the regional percentage. Materials would be subject to quality protocol to ensure they comply with this parameter. OTHER MEASURES RECOMMENDED TO ACHIEVE GOOD PRACTICE Contaminated Arisings and Hazardous Waste 7.12.7. The Principal Contractor would implement a Site Waste Management Plan (SWMP), to ensure that all hazardous wastes (as well as other arisings on site) are collected, transported, stored and disposed of in a manner that protects human health and the environment. Materials Management Plan 7.12.8. Materials storage should be discussed and agreed between the Principal Contractor and the Applicant. Arrangements for materials storage should be included in the Construction Phase plan. 7.12.9. Excavated soil should be re-used in line with an MMP meeting CL:AIRE Code of Practice requirements. Compliance would avoid the unnecessary disposal of re-usable material and the subsequent effect on landfill capacity. 7.12.10. The Environment Agency states that the following steps in waste management must be ensured by the Principal Contractor:
The waste must be classified. Any hazardous waste must be separated and stored safely. Authorised waste carriers must be registered, and waste sites should have environmental permits. Consignment notes must accompany all waste which is moved (one copy for the Principal Contractor and two copies for the carrier collecting the waste). Records must be kept in a register for 3 years at the premises that produced or stored the waste. RESPONSIBLE PURCHASING AND SUSTAINABILITY 7.12.11. The Principal Contractor would adopt resource efficient procurement practices that respond to any requirements set out in the Materials and Waste Chapter (Chapter 14 of the ES)and (where different) by:
Encouraging the use of materials with low embodied impacts, particularly re-used and recycled materials (e.g. aggregates) for use in the construction of roads, footpaths, cycleways and hard landscaping. Sourcing materials from suppliers that are located as close as possible to the Proposed Scheme. Sourcing timber from sustainable sources, which includes verifiable sustainably-managed forests (sources registered with the Forest Stewardship Council, Pan European Forest Certification or the UK Woodland Assurance Scheme).

7.13 NOISE AND VIBRATION 7.13.1. Legislative safeguards under section 60 and 61 of the Control of Pollution Act 1974 (CoPA) that limit noise emissions of construction plant are available to minimise the impacts of noise and vibration during the construction of the Proposed Scheme. 7.13.2. In addition to the legislative controls under CoPA, the adoption of Best Practicable Methods (BPM) is usually the most effective means of controlling noise and vibration from construction hot spots along the Proposed Scheme. This includes the adoption of the advice contained within BS 5228: 2009+A1:2014 Code of practice for noise and vibration control on construction and open sites. Part 1 – noise and part 2 – vibration. 7.13.3. Based on the principles of BPM, appropriate noise and vibration mitigation measures are likely to include the following, where reasonably practical:
Maintain good public relations with residents that may be affected by noise and vibration from the Proposed Scheme. Effective means of communication would be established, keeping residents informed of the type and timing of works involved; The Contractor would operate a telephone line which would provide the public and any stakeholders with a number to call if they have any complaints to make about the Contractor’s performance or if they wish to raise a concern. On receipt of any complaint, the Contractor would agree an approach to dealing with the complaint, including any changes to planned operations or procedures. Once all necessary measures have been put in place, the Contractor would formally respond confirming what measures have been taken to avoid any potential reoccurrence of an issue. Details of complaints, including the close out timescales to be formally recorded; Careful planning of construction activities and selection of appropriate plant to reduce noise emissions; All plant, equipment and noise control measures applied to plant and equipment would be maintained in good working order and operated such that noise emissions are minimised as far as reasonably practicable. Every effort would be made to ensure that plant, equipment or items fitted with noise control equipment found to be defective, are not operated until repaired; Noisy plant would be kept as far away as possible from sensitive receptors (and may need localised acoustic and visual screening); Fixed items of construction plant should be electrically powered in preference to diesel or petrol driven; Fabrication would take place off site; Noise from reversing alarms would be controlled or limited but cannot be eliminated for health and safety reasons. This would be undertaken through following a hierarchy of techniques: The site layout would be designed to minimise reversing; Banksmen would be used to avoid, so far as reasonably practicable, the use of reversing alarms; and Reversing alarms would incorporate, where reasonably practicable, features such as broadband signals to reduce the level of noise.
Shutting down equipment when not in use; Use of temporary barriers to screen noisy activities; Using silenced equipment where possible, in particular, silenced power generators if night-time power generation is required for site security or lighting;
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 63 of 70
Ensuring that vehicles do not park or queue for long periods outside sensitive receptors with engines running unnecessarily; Generators and water pumps required for 24-hour operation would be silenced and/or screened as appropriate; Soft start procedures for piling would be used; Avoid noise and vibration generating works outside standard working hours wherever possible, with works outside standard hours to be agreed pursuant to an application for ‘prior consent’ from Shropshire Council under Section 61 of the CoPA; A Toolbox talk and information leaflet would be provided to operatives when working outside of standard working hours to brief them on the requirements to be considerate to residents and any specific control measures required with each specific task being undertaken; For works outside standard working hours, silenced equipment and plant would be used, and/or temporary barriers would be installed to reduce noise at sensitive receptors to below BS 5228-1 threshold values where practicable; and At least two weeks prior to relevant works being carried out, the Contractor would distribute community notification letters to properties within 100 m of the Site, identifying the construction activities to be carried out and detailing expected disruptions and the measures being taken to minimise or mitigate adverse effects. 7.13.4. The potential attenuation of noise from construction activities through the use of the localised use of temporary site hoardings or noise barriers has not been included in the assessment of construction noise in order to represent a worst-case scenario. BS 5228 advises that noise barriers can provide a reduction in noise levels of 5dB when the top of the plant is just visible over the noise barrier, and 10dB when the plant is completely screened from a receptor. The effectiveness of a noise barrier depends upon its length, effective height, position relative to the noise source and to the receptors, and the material from which it is constructed. Therefore, the potential attenuation provided by any such barriers cannot be quantified at this stage. 7.13.5. Restricted working hours would be proposed adjacent to sensitive locations, such as residential dwellings and care home facilities. SURVEYS 7.13.6. Surveys would include physical measurements and observational checks/audits. Regular onsite observation surveys and checks/audits would be undertaken to ensure that BPM are being employed at all times. The site reviews would be logged, and any remedial actions recorded. Such checks would include:
Compliance with hours of working; Presence of mitigation measures e.g. engine doors closed, airlines not leaking and site hoarding in place; and Compliance with agreed working methods 7.13.7. Any required monitoring surveys during construction would be discussed with Shropshire Council and agreed as part of the finalised CEMP that the Principal Contractor would produce. 7.14 POPULATION AND HUMAN HEALTH 7.14.1. This section sets out the mitigation measures in minimising potential impacts on private property and housing; community land and assets; development land and businesses; agricultural land holdings;
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 64 of 70
walkers, cyclists and horse-riders (WCH); human health; driver stress; views from the road; and journey amenity. 7.14.2. The mitigation measures to be implemented in order to avoid, reduce or remedy potential impacts include the following:
WCH routes would remain open, where practicable, and where closures are necessary, route diversions would be in place where practicable; Public Rights of Way diversions would be agreed in advance with Shropshire Council; The design of routes for WCH would incorporate good practice with regards to safety, including street lighting provision; The design of the Proposed Scheme would ensure continual agricultural access to land during (where practicable) and following construction of the Proposed Scheme. Alternative access would be provided if inhibited; A Construction Traffic Management Plan would be prepared by the Principal Contractor and followed during construction. Any temporary road diversions or closures during construction phase would be clearly advertised and signed, and any diversionary routes should not lead to route uncertainty; An appropriate planting strategy as stated in Section 7.11 Landscape and Visual should be implemented to address areas of potential adverse visual effects due to the construction of the Proposed Scheme; and Mitigation for human health receptors are outlined in Sections 7.2 Air Quality, 7.13 Noise and Vibration and 7.15 Road Drainage and Water Environment. 7.14.3. Mitigation beyond the design commitments described above and to be adopted by the Contractor:
Access to residential properties and business premises would remain open, where practicable. Alternative access would be provided if inhibited; Local communities would be notified of any route diversions prior to commencement of construction; Temporary severance during construction would be reduced through careful siting of construction compounds and lay down areas, and careful planning of construction activities through consultation with landowners. Where the agricultural land holdings would be severed, efforts would be made to ensure continued access between severed land parcels during construction. Specific access requirements would be dependent on the nature of the farm holding and the scale of the impact or severance; Temporary land take from agricultural land holdings would be returned to former use and of at least equivalent quality once construction works have been completed. A detailed method statement would be produced, clearly identifying correct stripping, soil handling, storage, and placement and programming requirements to avoid compaction; Material storage would be in accordance with good site practice and the measures and documents as provided in Section 7.9 Geology and Soils; Diverted WCH routes and roads would be clearly signed to reduce route uncertainty; Measures would be put in place to maximise the potential for workforce and project supply chain to be sourced locally with local people and local businesses, where possible. This would ensure investment from the Proposed Scheme would stays in West Midlands; Monitoring would be undertaken to ensure acceptable working limits are adhered to using best practice methods;
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 65 of 70
As stated in Section 7.13 Noise and Vibration, restricted working hours would be proposed adjacent to sensitive locations, such as residential dwellings and care home facilities, to limit the exposure to noise pollution; A Flood Action Plan would be adopted and implemented to minimise the potential impact of flooding. In addition, works in the floodplain or watercourse during high flow events, intense rainfall events or when a flood warning is issued, would be avoided; and A Dust Management Plan, which may include measures to control other emissions, in addition to the dust and PM10 mitigation measures given within Section 7.2 Air Quality, would be developed and implemented by the Principal Contractor, and approved by Shropshire Council. 7.15 ROAD DRAINAGE AND WATER ENVIRONMENT 7.15.1. The commitments relating to the water environment within this CEMP have been drawn from the assessment of significant effects upon the water environment (surface water and groundwater) which is included in Chapter 10 and Chapter 17 of the ES (including all associated appendices). 7.15.2. The Principal Contractor should implement standard good practice pollution prevention measures in construction to protect the surrounding water environment (surface water and groundwater). These could include: SEDIMENT AND POLLUTION CONTROL
Avoid the positioning of stockpiles near to watercourses, ensure they are located outside of the flood zone; Stockpiles should be located a minimum of 10m from the top of bank of any watercourse; Cover stockpiles when not in use; Contain stockpiles with bunds or sediment fences; Use a sediment trap to treat surface runoff; Control of runoff during construction. This may include creating temporary drainage systems to both alleviate flood risk and help to prevent sediment laden runoff entering the watercourse; Cut-off drains would be used uphill and downhill of the working areas to prevent clean runoff entering and dirty water leaving the working area without appropriate treatment; All drains within the construction area would be identified and labelled and measures implemented to prevent polluting substances from entering them; All proposed road drainage outfalls would be constructed to current good practice standards to reduce the impact on the geomorphology of the relevant watercourses. This would include construction of the outfall structures which would be generally constructed to the watercourse bank slope profile. Outfall structure headwalls, wingwalls and erosion protection aprons, if required, would be designed to prevent erosion of the bed and banks of the watercourse; Areas with a great risk of spillage (e.g. vehicle maintenance and storage areas for hazardous materials) would be carefully sited (e.g. away from drains or areas where surface waters may pond); Emergency response plans would be developed, and spill kits made available on site; Measures to be put in place to prevent pollution from construction plant, vehicles and machinery including refuelling and lubricating in designated areas, on an impermeable surface, with appropriate cut-off drainage located away from watercourses; plant to be maintained in a good condition with wheel washing in place (avoiding vehicle cleaning near to existing watercourses), all refuelling would be supervised and carried out in a designated area. In the event of plant
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 66 of 70
breakdown, drip trays would be used during any emergency maintenance and spill kits would be available on site; Fuels and potentially hazardous construction materials would be stored in bunds that have areas with external cut-off drainage; fuel would be stored in double skinned tanks with 110% capacity; Construction plant would be checked regularly for oil and fuel leaks, particularly when construction works are undertaken in or near existing waterbodies; Waste fuels and other liquid contaminants would be collected in leak-proof containers prior to removal from site to a permitted recycling processing facility; Oil absorbent booms would be made available on site and deployed in the event of a significant spillage; Procedures to control dust and contain debris associated with demolition works; Control and treatment measures would be regularly inspected to ensure they are working effectively; Concrete wash out would only take place at designated concrete washout areas; Avoid pumping or similar processes of concrete over or adjacent to open water where possible and close observation to swiftly shut off any pumps if a spillage occurs; Surface water run-off and excavation dewatering would be captured and settled out prior to disposal to sewer as appropriate. Any contaminants to be removed prior to disposal; The use of temporary cofferdams to exclude work areas from the main River Severn waterbody, thus reducing the risk of increased sediment loads or hazardous substances entering the main water flow; Provide sediment barriers between earth works and the construction zone and the watercourse to prevent sediment from washing into the river. Silt management needs to be considered not only adjacent to the watercourse, but also up the valley sides to minimise fine sediment input to the watercourse. An exclusion zone of 8m from the watercourse and top of the valley sides should be maintained as far as practicable; The use of silt fences, silt traps, filter bunds, settlement basins and/or proprietary units such as a ‘siltbuster’ to treat sediment laden water generated on site before discharge; Sewage generate from site welfare facilities would be disposed of appropriately. This may be by discharge to the foul sewer network or by collection in septic tank for disposal off site; Compliance with the relevant sections of BS6031:2009 Code of Practice for Earthworks (British Standards, 2009) with respect to protection of water quality and control of site drainage including washings, dewatering, abstractions and surface water; and The creation of a dry-working area for pier construction is within the floodplain; temporary measures to prevent inundation during out of bank flow would reduce the risk of silt laden runoff from draining from the excavation site. Impacts on flow would occur in the event of out-of-bank flows that encroach on the construction zone; and, The use of soft start piling techniques to minimise the disturbance and subsequently mobilisation of contaminated sediment within the River Severn during construction of the viaduct substructures. CONTROL OF HYDROLOGICAL IMPACT
Minimise as far as practicable the construction zone for the installation of the piers to reduce the impacts of flow constriction should out-of-bank flows occur during the construction period;
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 67 of 70
Avoid undertaking works adjacent to the watercourse, where practicable. When working adjacent to the watercourse is required, maintain the maximum distance possible from the watercourse along with appropriate mitigation outlined above for fine sediment management. VEGETATION CLEARANCE
Limit the clearance of vegetation on the channel banks, valley sides and riparian zone. Where practicable, maintain a vegetated buffer strip between the construction zone and the watercourse. Ideally, a minimum buffer strip of 8m should be retained where possible. Where works are required on the watercourse banks, or in-channel, vegetation clearance should be restricted to the working area and should be undertaken only immediately prior to the commencement of those works, except for other circumstances where earlier clearance may be required due to the presence of protected species. Vegetation should be re-established as soon as practicable. If necessary, additional measures such as geotextiles (biodegradable and non- biodegradable), willow spiling, mulching, brushwood mattresses etc. should be used to protect soils before vegetation has re-established, particularly on the watercourse banks; Use seeded biodegradable fibre matting to encourage re-vegetation after works on, or near, the banks as appropriate. Installation of willow spiling to both provide green bank protection and to mitigate loss of riparian habitat; and, Maintaining, where possible, vegetation cover on the banks close to the river and prompt reinstatement of vegetation to minimise the impact of reduced roughness, which would have knock-on impacts on flow velocity, stream power and shear stress and thus sediment transport capability through the construction zone. TIMING OF WORKS
Avoid works during high flow events to reduce the risk of fine sediment release. Target the construction activities for the drier summer months to reduce this risk, taking into account the window for construction activities in relation to aquatic ecology and, in particular, the fish migratory season; Avoid critical periods for fish migration and spawning. The window for undertaking works in or near rivers is typically toward the end of May to October; Undertaking the construction works during the late-spring and summer period typically coincides with lower flow conditions, less precipitation and reduced risk of high flow events, thus reducing the risk of the impacts listed above; Avoid construction activities during high flow events and heavy rainfall. Monitoring of flows and rainfall within the upstream catchment should be undertaken and action taken to holt works should high flows be anticipated due to prevailing weather conditions; and, All relevant consents should be sought from the EA for temporary discharges and in-stream works affecting Main Rivers, and from Shropshire Council for in-channel works in ordinary watercourses. 7.15.3. A programme of water quality (surface water and groundwater) monitoring may also be required to satisfy potential discharge consent conditions. If licences are required, it would be agreed with the relevant stakeholders prior to the regulated activity commencing, and works would be carried out under the licence conditions. 7.15.4. Prior to construction the Principal Contractor would:
SHREWSBURY NORTH WEST RELIEF ROAD PUBLIC | WSP Project No.: 70056211 | Our Ref No.: 70056211-WSP-EGN-AS-RP-LE-00008 February 2021 Shropshire Council Page 68 of 70
Follow the Environment Agency's Approach to Groundwater Protection Guidance to avoid potential contamination risks in aquifers and groundwater abstractions; Ensure that dewatering rates would be such that no infringement upon the licensed abstraction zone of influence for both the construction and post-construction (6 months post construction) phases; and The construction dewatering method of discharge has yet to be determined. The groundwater collected would either be discharged to surface water, sewer, disposed off site or a combination of these three methods. If the water is to be discharged to sewer or a surface waterbody then a discharge consent(s) may be required. The permitting process would be completed by the Contractor once a dewatering and discharge management methodology has been agreed upon. The Contractor would be responsible for acquiring the relevant consents and adhering to the conditions of said consents. 7.16 FLOOD RISK 7.16.1. The impact assessment has informed the development of the planning and design proposals in the form of relevant measures targeted at mitigating potential flood risk impacts associated with the Proposed Scheme. 7.16.2. The measures to avoid, reduce or remedy potential flood risk impacts associated with the operation of the Proposed Scheme are detailed in Chapter 17 of the ES and the accompanying FRA (Appendix 17.2). 7.16.3. Mitigation beyond the design commitments described above and which would be incorporated by the Principal Contractor where practicable would include:
Adoption and implementation of a Flood Action Plan; Sign up for flood warnings and check online warnings regularly when appropriate i.e. following periods of heavy rainfall; Avoid works in the floodplain or watercourse during high flow events, intense rainfall events or when a flood warning is issued; A description or map showing locations of key property, protective materials and service shut-off points; Basic strategies for protecting property, preventing business disruption and assisting recovery; Checklist of procedures that can be quickly accessed by staff during a flood; Site compound(s) to be located outside of the floodplain; Materials and mobile machinery to be stored outside the floodplain; If a flood warning is received from the EA, move all machinery and equipment out of the floodplain. If this cannot be completed in a safe time, secure equipment to prevent it being washed away; All relevant consents would be sought as required from the EA for any temporary works or permanent structures within 8m of a ‘main river’ watercourse and from SC in relation to works impacting on ordinary watercourses; and, Discharges would be limited to discharge rates for temporary drainage systems agreed with Shropshire Council during the consent process. 7.16.4. There is potential risk of groundwater flooding during construction. Any residual groundwater flooding risk during construction should be managed using the flood management plan and anyone working on site should be made aware that there is potential groundwater flooding to the site.

Procedure Waste and Materials Management
Ref: PEP/01
Action by: Principal Contractor and Site Environmental Manager
Purpose: Management of storage, handling, movement and disposal of waste materials
Materials General: management: The Principal Contractor should be responsible for implementing management systems and processes that consider the resource efficient management of materials at site. Any materials or arisings generated during on-site works would be identified and classified at Site, to facilitate separation, correct storage, reuse and disposal. For structure or their components, materials would be purchased in a form that minimises the creation of offcuts/waste e.g. prefabricated assets. Use of materials with recycled or secondary content would be prioritised, where safety and quality can be assured. Excavations that can be reused as landscaping and/or fill, either on (or off) site would be managed in accordance with an MMP that is compliant with the CL:AIRE Definition of Waste - Code of Practice. Materials and products designed for deconstruction and easy access / adaptability, would be prioritised. The Principal Contractor would be responsible for collating and providing to the Client information on resource efficiency measures adopted, alongside quantified achievements / savings made. The Client would agree with the Principal Contractor the extent of the information to be provided, but it should include (for example), material consumption avoided, quantity or recycled or secondary material installed, volume of and waste avoided. Segregation and storage:
Any materials kept on at Site would stored so as to reduce the risk of wastage. Where feasible, materials would remain in their protective packaging until they are used. Materials to be used on the Scheme may be temporarily stored and used as temporary screening, where safe to do so. The Principal Contractor would, where possible, engage with suppliers using returnable or practicably recyclable packaging. Hazardous materials:
In general, the use of hazardous materials should be minimised wherever practicable. The Principal Contractor would be responsible for identifying suitable areas for the storage of oils, fuels, chemical and other hazardous construction materials.
Waste General: management: The Principal Contractor should be responsible for implementing management systems and processes that manage of Site waste in accordance with the highest tiers of the Waste Hierarchy and the Proximity Principle.
