PART 1 – INTRODUCTION AND PROJECT STRUCTURE



(CEMP)


1. INTRODUCTION

1.1 Background and Context

1.1.1 This Construction and Environmental Management Plan (CEMP) has been prepared for Warwickshire County Council (hereinafter referred to as the ‘Employer’) for use on the A46 Stoneleigh Road Project.

1.1.2 It sets out the strategy for how the Principal Contractor will meet and manage the Construction and Environmental Requirements associated with the project and reports on how the construction activities associated with the junction improvement works are undertaken. This Plan shall only be for the works associated with the A46 Stoneleigh Road junction in Warwickshire (hereafter referred to as the ‘Site’), located at Ordnance Survey Grid Ref SP320734.

1.1.3 The existing junction comprises of a single carriageway bridge carrying the C32 Stoneleigh Road above the three lane A46 dual carriageway. Two slip roads allow unrestricted access north and south from the C32 onto and off from the A46. At the point where the slip roads meet the C32, there are two priority crossroads.

1.1.4 The C32 continues from the A46 bridge north west towards the University of Warwick and approximately 300m from the bridge, there is an existing roundabout at the junction of Stoneleigh Road and Dalehouse Lane. Stoneleigh Road then continues to the north west, crossing Finham Brook and heads towards Coventry.

1.1.5 The project will seek to deliver major improvements in the operation of the A46Stoneleigh Road junction, through the introduction of an elevated gyratory and improved junction approaches. This would improve highway safety, highway capacity, accesses to local businesses and reduce journey times. The project would also help address existing congestion and safety issues at the junction, whilst also improving access to the University of Warwick and Stoneleigh Park.

1.1.6 The project proposals (hereinafter referred to as the ‘Works’) include the installation of a new bridge over the A46 to the north-east of the existing junction, thereby creating a new grade separated gyratory roundabout over the A46. This roundabout will be partially signal controlled to help the flow of traffic around the gyratory and local roads. The existing bridge will be retained, but reconfigured to create an additional lane added within the bridge deck.

1.1.7 The Works will also involve constructing a new Stoneleigh Road/Dalehouse Lane roundabout and a new bridge over Finham Brook. Comprehensive shared footway/cycleway facilities will be provided throughout the scheme and this will include four signalised toucan crossings on all four slip roads.

1.1.8 The permanent speed limits on the local roads will all be amended to be a proposed 50mph throughout. The main A46 and slip roads will be retained as national speed limit.

1.1.9 The construction process will comprise extensive disturbance throughout most of the Site footprint lying within the application boundary, not only for the new bridges and road and road junctions but also in relation to the construction of access roads and any areas required for storage of materials.

1.1.10 The production of a Construction and Environmental Management Plan (CEMP) is required by Condition 20 of the Planning Permission Decision Notice (dated 17th July 2018) Application Number WDC / 17CC015. This is discussed in more detail in Section



(CEMP)


1.2 Objectives and Purpose of the CEMP

1.2.1 This CEMP has been drafted to document the procedures and working practices that shall be employed on this project to deliver the Works whilst also mitigating any potential adverse impacts on the environment that may arise due to the construction operations.

1.2.2 It is intended to focus on the targeted pre-commencement checks and appropriate communication lines to ensure all who are required to know are familiar with the information and processes contained within this document.

1.2.3 The CEMP will largely follow the requirements outlined in ISO 14001, the guidance contained within the Institute of Environmental Management and Assessment's “Best Practice Series Volume 12, December 2008 "Environmental Management Plans" and CIRIA guidance C692 "Environmental Good Practice on Site (Third Edition)" as well as Interim Advice Note (IAN) 183/14.

1.2.4 As such the objectives of this CEMP are to:

i. Registering all applicable environmental aspects (effects of the Works);

ii. Establish Project Team roles and responsibilities and assign a line of communication that extends to other parties involved in the Contract, e.g. sub-Principal Contractors;

iii. Outline and document all key environmental risks and the measures for addressing them;

iv. Describing the key consents, approvals and permissions for environmental aspects of the works;

v. Documenting the methodology for dealing with changes on site that may require the methodologies and working practices outlined in this document to be changed added to or removed;

vi. Determining the methods by which the appropriate environmental data required for handover and maintenance will be captured;

vii. Instituting procedures for the periodic review and monitoring compliance with the measures described in this CEMP; and

viii. Establishing emergency procedures in the event of an environmental emergency.

1.2.5 The CEMP is a practical working document which shall be monitored and updated during the life of the project. Adherence to the CEMP does not substitute any legal or planning obligations on the Employer or Principal Contractor, or the need for an on-going appraisal of site activities to determine unforeseen events and the design of any appropriate remediation measures. However, the CEMP provides a set framework against which to manage and monitor activities on the site.

1.2.6 All records required and associated with this plan will be maintained in a suitably referenced filing structure and shall be accessible for any user and subsequent archiving.



(CEMP)


1.3 Structure of the CEMP

1.3.1 This CEMP has been split into four parts as follows:

i. Part 1 – Introduction and Project Structure;

ii. Part 2 – Existing Site Information and Baseline Conditions;

iii. Part 3 – Active Measures – CEMP Site Specific Controls; and

iv. Part 4 – Reactive Measures – Incident Procedures

1.3.2 The project and this CEMP acknowledges that there needs to be a distinction made between different type of procedures and monitoring during the construction of the Works. Therefore, Part 3 details Active Measures which are controls that are put in place designed to stop an environmental incident occurring whereas Part 4 details the Reactive Measures which are to be implemented in case of an incident occurring.

2. REGULATORY FRAMEWORK & PLANNING CONDITIONS

2.1 Relevant Legislation

2.1.1 There are a number of legislations in place that govern how the environment is monitored and to ensure it is not adversely affected. The key Legislation believed to be applicable to this CEMP are outlined in Table 1 below.

Planning Condition Number

Planning Condition Text Environmental Discipline Affected

3 Work which is likely to give rise to noise levels that are above 34dBA where background noise levels are no more than 24dBA, or 10dBA above the background noise level if this is more than 24dBA shall be restricted to the following hours:

Mon-Fri 0700 – 1900, Sat 0730 – 1300

Piling and activities such as hydro demolition shall be restricted to Monday – Friday between the hours of 0800 and 1700.

No construction operations shall take place on Sundays or Public Holidays unless otherwise agreed in writing with the County Planning Authority.

Noise

5 In the event that contamination is found at any time when carrying out the approved development that was not previously identified, it must be reported in writing immediately to the County Planning Authority. An investigation and risk assessment must be undertaken, and, where remediation is necessary, a remediation strategy must be submitted to and approved in writing by the County Planning Authority. Following completion of measures identified in the approved remediation scheme, a verification report must be prepared and approved in writing by the County Planning Authority.

Contaminated Ground

6 Prior to the commencement of development, a construction management plan shall be submitted to and approved in writing by the County Planning Authority. The construction management plan shall include details of:

• Any temporary measures required to manage traffic during construction

• Plans and details of haul roads within the site and for the turning and unloading and loading of vehicles within the site during construction

• Dust management and suppression measures – level of mitigation determined using IAQM guidance

• Wheel washing

• Noise assessment and mitigation method statements for the construction activities in accordance with the provisions of BS 5228:2009 Code of Practice for Noise and Vibration Control on Construction and Open Sites – Parts 1 and 2

• Concrete crusher if required or alternative procedure

• Site lighting

Noise, Dust, Non-motorised users



(CEMP)




• Access and protection arrangements around the site for pedestrians, cyclists and other road users

• Restrictions on burning and details of all temporary Principal Contractors’ buildings

• Plant and storage of materials associated with the development process

• External safety and information signing notices

• Complaints procedures, including complaints response procedures and dedicated points of contact

Construction activities shall be carried out in accordance with the approved scheme.

7 A landscape and ecological management plan (LEMP) shall have been submitted to and approved in writing by the County Planning Authority prior to the commencement of the development. The content of the LEMP shall include the following:

• Description and evaluation of features to be managed

• Ecological trends and constraints on site that might influence management

• Aims and objectives of management

• Appropriate management options for achieving aims and objectives

• Prescriptions for management actions

• Preparation of a work schedule (including an annual work plan capable of being rolled forward over a five-year period)

• Details of the body or organisation responsible for implementation of the plan

• Ongoing monitoring and remedial measures

The LEMP shall also include details of the legal and funding mechanism(s) by which long term implementation of the plan will be secured by the developer with the management body(ies) responsible for its delivery. The plan shall also set out (where results from monitoring show that conservation aims and objectives of the LEMP are not being met) how contingencies and/or remedial action will be identified, agreed and implemented so that the development still delivers the fully functioning biodiversity objectives of the originally approved scheme. The approved plan shall be implemented in accordance with the approved details.

Landscaping, Ecology

8 No development shall commence unless and until a scheme ("the scheme") to ensure that there is no net biodiversity loss as a result of the development has been submitted to and agreed in writing by the County Planning Authority. The net biodiversity impact of the development shall be measured in accordance

Landscaping, Ecology



(CEMP)




with the DEFRA biodiversity offsetting metric as applied in the area in which the site is situated at the relevant time and the scheme shall include:

• proposals for on-site mitigation (full details of which will be provided in relation to each phase of development in accordance with Condition 7 of these conditions)

• if and to the extent that a net biodiversity loss cannot be avoided by on-site mitigation alone, proposals for off-site offsetting

• a methodology for the identification of any receptor site(s) for off-site offsetting measures;

• the identification of any such receptor site(s);

• the provision of arrangements to secure the delivery of any off-site offsetting measures (including a timetable for their delivery); and

• a management and monitoring plan (to include arrangements for the provision and maintenance of any off-site offsetting measures in perpetuity).

The written approval of the County Planning Authority shall not be issued before the arrangements necessary to secure the delivery of any off-site offsetting measures have been executed. The scheme shall be implemented in full accordance with the requirements of the scheme or any variation so approved.

9 The development hereby permitted shall not commence until a Construction and Ecological Management Plan has been submitted to and approved in writing by the County Planning Authority. The Plan shall include details of monitoring of the otter couch and any otter nesting sites prior to and during works, pre-commencement checks for badgers, bats, breeding birds, otters, reptiles and amphibians, and appropriate working practices and safeguards for wildlife and habitats plus any mitigation required that is to be employed whilst works are taking place on site. The agreed Construction and Ecological Management Plan shall thereafter be implemented in full.

Ecology

10 The development hereby permitted shall not commence until a qualified ecologist has been appointed by the applicant to inspect the structures and vegetation to be cleared on site for evidence of nesting birds immediately prior to works. If evidence of nesting birds is found works may not proceed in that area until either the nesting bird season (March to September inclusive) has ended or until after the young have fledged, as advised by the ecologist.

Ecology

12 No part of the development hereby permitted shall be commenced and no equipment, machinery or materials shall be brought onto the site until a scheme for the protection of all existing trees and hedges to be retained on site has been submitted to and approved in writing by the County Planning Authority and has been put in place. The scheme must include details of the erection of stout protective fencing and be in accordance with British Standard BS5837:2012, Trees in relation to design, demolition and construction. Nothing shall be stored or placed in those areas fenced in accordance with this condition and nor shall the ground levels be altered or any excavation take place in those areas without the prior consent in writing of the County Planning Authority. The approved scheme shall be kept in place until all parts of the

Aboriculture



(CEMP)




development have been completed and all equipment and machinery and surplus materials have been removed.

13 No development shall take place until a programme of archaeological survey work has been implemented in accordance with a written scheme of investigation which has been submitted by the applicant and approved in writing by the County Planning Authority.

Cultural Heritage

14 The development permitted by this planning permission shall be carried out in accordance with the approved Flood Risk Assessment (FRA) and associated Flood Risk Assessment Report - Addendum 06/03/2018 and in particular flood plain compensation will be created upstream of the bridge.

Flood Risk

20 No development shall commence until a Construction Environmental Management Plan for the development has been submitted to, and approved in writing by, the County Planning Authority. The approved Plan shall be adhered to throughout each construction phase.

All disciplines

2.2.3 Planning conditions 3 (noise), 5 (contaminated ground) and 14 (flood risk) do not require pre-commencement conditions to be discharged but the conditions need consideration in the CEMP and so will be reported under the appropriate sections of this document.

2.2.4 Planning condition 10 requires an ecologist to be appointed to inspect various items before any site clearance takes place. An application has already been made to the Planning Authority and this condition was discharged on 04th September 2019. However, the mechanisms by which the ecologist will undertake these inspections is documented in the Ecological – Construction Environmental Management Plan (E-CEMP) required under Condition 9.

2.2.5 Condition 13 required a programme of archaeological survey work to be undertaken which has been already been completed and the planning condition was discharged on 29th August 2019.. However, there is a requirement for part of the Works to be carried out under archaeological control and the mechanisms for this brief shall be captured in this CEMP.

2.2.6 Condition 8 requires information for the biodiversity offsetting produced by the scheme proposals. This is considered to be outside the scope of this CEMP and is indirectly related to the long-term landscaping maintenance after the scheme construction is completed. This will be tied into Condition 7 which outlines the need for a long-term landscaping management plan (LEMP), the first year of which will fall under the Works.

2.2.7 Conditions 6 (Construction Management Plan), 7 (LEMP), 9 (E-CEMP), 12 (Tree Protection Plan), 20 (Production of the CEMP) are conditions that require discharge pre-commencement of the works. As these individual conditions will be collected under the umbrella of the CEMP - but still need to be distinctive items to allow for application for condition discharge - it is proposed to have these documents as standalone sections within the CEMP.

PART 2 – EXISTING SITE INFORMATION AND BASELINE CONDITIONS



(CEMP)


4. SITE LOCATION AND EXISTING SITE CONDITIONS

4.1.1 The A46 Stoneleigh Junction is located on the A46 between Coventry and Kenilworth at the junction with the C32 Stoneleigh Road. It provides principal access from the Strategic Road Network (SRN) to Warwick University and the National Agriculture and Exhibition Centre (NAEC) at Stoneleigh.

4.1.2 The existing junction compromises a single carriageway bridge carrying the C32 Stoneleigh road above the three lane A46 dual carriageway. Two Lane slip roads allow unrestricted access north and south from the C32 onto and off from the A46. At the point where the slip roads meet the C32, there are two priority cross roads.

4.1.3 The C32 continues from the bridge north west towards the University of Warwick and approximately 300m on from the bridge, there is an existing roundabout at the junction of Stoneleigh Road and Dalehouse Lane which provides connectivity into Kenilworth from the east. The road crosses Finham Brook to the north west of the Dalehouse Lane Roundabout.

4.1.4 Heading south east from the existing A46, the C32 links into the B4115 which provides onwards connections towards Leamington Spa.

4.1.5 Stoneleigh Road does include for footway provision on the existing A46 overbridge and along a section of the road to the east of the junction. However, there is no other footway access on the main C32 road itself. A public footpath – Centenary Way - passes alongside the A46 northbound off slip and along a section of Stoneleigh Road until the Stoneleigh Road/B4115 junction.

4.1.6 The surrounding land is dominated by arable land with some improved and semi improved grassland, small areas of woodland, hedgerows, scrub and ponds. Finham Brook lies to the west and north of the junction and flows from the southwest to the northeast.

4.1.7 The earliest historical maps dating from 1886 shows the area of the A46 junction was used as agricultural fields. A track along the alignment of Stoneleigh Road is shown to be present at this time. Dalehouse Lane is present on its original alignment close to, and parallel with Finham Brook. Dalehouse Lane has a junction with Stoneleigh Road approximately 50m from Finham Brook.

4.1.8 There was very little change until the construction of the A46, first shown on mapping from 1983. This map also shows the realignment of Dalehouse Lane on the approach to Stoneleigh Road with a new triangular junction. This triangular junction has changed to the current roundabout on 2006 mapping.

4.1.9 An assessment of neighbouring land uses was undertaken in 2018 and identified the current neighbouring land as follows:

i. North – A46 and agricultural fields;

ii. South – A46 and agricultural fields;

iii. East – Agricultural fields; and

iv. West – Agricultural fields and Finham Brook.

An aerial image of the existing junction from 2018 is shown in Figure 5.



(CEMP)


Figure 5: Aerial Image of Existing Junction circa 2018

5. EXISTING SITE – NEARBY FEATURES

5.1.1 There are a number of residential properties to the north of Dalehouse Lane, including: Croyde Hoe, Knysna, Finbrook, Barnfield, Westley House, High Lo and the Cottage. There are other farmhouses in the area including Manor Fields Farm, Kingswood House and Kingswood Farmhouse.

5.1.2 An area of land to the south of Stoneleigh Road (between Dalehouse Lane and Finham Brook) is currently used for beekeeping activities. North of Finham Brook (along Stoneleigh Road), is an area of land used for commercial use at Brook Farm. There are a number of agricultural accesses to fields either side of Stoneleigh Road between the A46 and Finham Brook.

5.1.3 Approximately 800m south of the existing A46/Stoneleigh Road junction, there is proposed to be the crossing of the High Speed 2 (HS2) railway line. Traffic associated with the HS2 works is expected to use the Stoneleigh junction as a haulage route, thereby increasing traffic flows (particularly lorries) in the area for a number of years.

5.1.4 In the field to the north of Stoneleigh Road east, there is a proposal to construct the Rugby Farmers’ Market which is a new development.

5.1.5 In the fields to the south of Dalehouse Lane, there is an existing Public Right of Way (PROW), route K29. The PROW crosses over the field before running along the boundary of the A46 northbound off slip road before finally providing a stepped access to the road at the top of the northbound off slip.



(CEMP)


6. ECOLOGICAL BASELINE CONDITIONS

6.1.1 An Ecological Impact Assessment (EcIA) was completed by the Employer in December 2017 and was used to support the planning application. This EcIA document formed the basis of a baseline assessment of ecological conditions and more detail can be found in the Ecological – Construction Environmental Management Plan (E-CEMP) contained in Appendix B.

6.1.2 The E-CEMP document is to be read in conjunction with this CEMP. To provide a distinction between the Construction Environmental Management Plan and the Construction Ecological Management Plan, the former is abbreviated to CEMP (and is this document), whereas the latter is abbreviated to CEMP with the E prefix (e.g. E-CEMP) and is contained in Appendix B.

7. EXISTING GROUND CONDITIONS

7.1.1 Ground investigation work has been undertaken during the development of the scheme which outlines that the ground largely comprises Kenilworth Sandstone Formation which comprises both sandstone and mudstone. The Formation was typically described as a medium dense silt/gravel sand which may in areas be cohesive.

7.1.2 Made ground is present close to the A46 as part of the northbound off-slip which is to be constructed on an embankment. Further made ground is located near Finham Brook and there are also alluvial and river terrace deposits in proximity to the Brook and these extend to depths of 3, to 4m below existing ground level.

7.1.3 No areas of contamination were noted during any ground investigation testing undertaken during the design development. However, it is expected that the ground in the area around Finham Brook is contaminated with the seed for Himilayan Balsam and this is documented further in the next section.

7.1.4 No mines or mineral deposits were identified within 500m of the site and no recorded landfills are present within 1km of the site.

7.1.5 Information from the Environment Agency revealed that the bedrock of the site is a Principal aquifer and the superficial deposits are a Secondary A aquifer. The site lies entirely within Zone 3 of a groundwater source protection zone.

7.1.6 An archaeological evaluation was undertaken between January and February 2017. This revealed no features were recorded to the west of the A46. An undated ditch parallel to the existing boundary was recorded to the east of the A46. No archaeological finds were made.

8. AREA IN AND AROUND FINHAM BROOK

8.1.1 The Works are required to take place in and around Finham Brook. Finham Brook is a salmonid river and there are risks to the environment of the river during any construction operations. The main environmental issues when working in the vicinity of the Brook are as follows:

i. Finham Brook is located in a flood zone;

ii. It is a salmonid watercourse; and



(CEMP)


iii. Areas around the river contain Himalayan Balsam.

8.1.2 Following discussions with the Environment Agency, the risks to the river are deemed to be as follows:

iv. The construction operations create a flood risk;

v. Damage to the ecology of the river through construction operations; and

vi. The construction operations allow the spread of Himalayan Balsam which is in the area.

8.1.3 A summary of the environmental risks in this area is shown on drawing 9.2-A46-083-190 which is contained in Appendix C.

9. EXISTING TREES

9.1.1 A survey of existing trees has been undertaken which has identified a number of critical mature trees to be retained in and around the site. These trees are to be retained during the Works and a Tree Protection Plan has been put in place which outlines the methods by which this shall be done. A copy of this plan is contained in Appendix K.



(CEMP)


PART 3 – ACTIVE MEASURES – CEMP SITE SPECIFIC CONTROLS



(CEMP)


10. GENERAL

10.1.1 The following control measures have been developed to best reflect the actual methods of working during the construction period.

10.1.2 The environmental standards for the site have been determined and detail the minimum measures that will be applied for general operations that fall outside the risk assessment and/or method statements.

10.1.3 Where necessary, these are outlined in the relevant sections below.

11. ENVIROMENTAL RISK ASSESSMENTS

11.1.1 All activities to be undertaken on site have had an Environmental Risk Assessment carried out by the Principal Contractor. The Risk Assessment has been undertaken by trained staff following an approved procedure. The assessment has:

i. Identified the significant environmental impacts that can be anticipated;

ii. Assessed the risks from these impacts;

iii. Identified the control measures to be taken and re-calculate the risk; and,

iv. Report where an inappropriate level of residual risk is identified so that action can be taken through design changes, re-scheduling of work or alternative methods of working to reduce the risk to an acceptable level.

11.1.2 The results of a risk assessment and their residual risks are only considered acceptable if:

i. the severity of outcome is reduced to the lowest practical level;

ii. the number of risk exposures are minimised;

iii. all reasonably practical mitigating measures have been taken and the residual risk rating is reduced to a minimum.

11.1.3 The findings of the risk assessment and the necessary controls will be explained to all operatives before the commencement of the relevant tasks using an agreed instruction format.

11.1.4 The Risk Assessments are contained in Appendix H.

12. METHOD STATEMENTS

12.1.1 Method Statements have been prepared by the Principal Contractor (or, where necessary by Sub Contractor or Suppliers) by competent, trained experienced personnel. These documents have been prepared in consultation with on-site environmental staff and, where necessary, environmental specialists.

12.1.2 Their production has included a review of the environmental risks and commitments, (as identified in the risk assessment outlined in the previous section), so that appropriate control measures are developed and included within the construction processes.



(CEMP)


12.1.3 Method Statements have been reviewed by the SHEQ Manager, and, where necessary, by an appropriate environmental specialist. Where necessary, Method Statements will be submitted to the enforcement agencies (Environment Agency, Natural England, Environmental Health Officer etc) as appropriate.

12.1.4 The Method Statements are contained in Appendix H.

13. AIR QUALITY - DUST & EMISSIONS

13.1.1 Dust deposition can harm vegetation and cause potential habitat loss, particularly if present in significant quantities. There is potential for dust to reach both on-Site and adjacent designated sites and habitats as a result of construction activity.

13.1.2 Dust levels during construction are not expected to be problematic, although dust suppression will be required during dry conditions. Care will be required to maintain dust emissions at a practicable minimum when working in the vicinity of residential properties and environmentally sensitive areas. Best practice mitigation will be required during dry conditions.

13.1.3 The site will adopt a control of dust at source approach by limiting where possible the materials and operations that will produce dust. The following protocols will be adopted for this site:

Site Vehicle Usage

i. Reuse or construction of new road surfaces to limit the dust arisings that may occur from moving vehicles across the site. Where necessary, this will be in the form of a haul road constructed from suitably compacted material to prevent dust arising;

ii. The implementation of a site wide policy to not have idling engines for vehicles not in use. These shall be switched off;

iii. Routing all site vehicles aware from sensitive environmental and ecological features where possible;

iv. Limiting the fall distance for materials onto lorries or into the Works; and

v. Ensuring that all vehicles are suitably well maintained so that exhaust emissions do not breach statutory limits.

Equipment and Material Usage

vi. Restrict cutting or grinding operations (such as cutting concrete or any cutting activity likely to result in a lot of dust arising) to certain locations and away from environmentally sensitive areas;

vii. Wherever possible, fitting equipment likely to produce a lot of dust with suppression equipment, e.g. vacuums or water sprays;

viii. Limiting the fall distance for materials onto lorries or into the Works;

Other Measures

ix. Stockpiling and storing materials in an appropriate manner to ensure that dust particles are prevented from becoming airborne. This may include sealing and seeding of the stockpiles;



(CEMP)


x. Where necessary, damping down construction operations – particularly bulk earthworks – during dry weather to minimise dust particles becoming airborne;

xi. Erecting fencing and/or hoarding to limit dust dispersion and prevent any unauthorised access from wildlife;

xii. Banning the use of fires or any form of burning on site; and

xiii. Regularly sweeping all roads, footways and/or hard standing areas.

13.1.4 Construction operations will be monitored for dust. Colas SIAC site staff will visually monitor activities which can be reponsible for production of dust. Preventative measures will be implemented to prevent production of dust. Colas SIAC control methods are presented in point 3.8.2 of the CPP.

13.1.5 The Construction Project Manager will ensure that the source of any identified air quality problem is determined and immediately implement the appropriate mitigation action to address the issue. The action taken shall be recorded and shall include for a period of monitoring whereby the effectiveness of the mitigation action shall be determined.

13.1.6 Where the mitigation action successfully controls the spread of dust, this shall be recorded and no further action is necessary. Where it does not, the Construction Project Manager will work up an action plan to address the issue and implement it as soon as possible. If necessary, this may include suspending the operation until appropriate control measures can be put in place.

13.1.7 All records shall be kept and made available as part of the regular review of the effectiveness of the CEMP.

14. ARCHAEOLOGY & CULTURAL HERITAGE

14.1.1 In 2017, the Employer undertook a series of on site archaeological investigations that formed part of the planning application. The work was carried out in accordance with the Chartered Institute for Archaeologists Standards and Guidance for Field Evaluation 2014.

14.1.2 Twenty-eight trial trenches were excavated across the site and locations of the trenches can be seen in the plan in Appendix I. The single feature found was a shallow and undated ditch. No archaeological remains of national significance were found as part of the investigations.

14.1.3 However, there remains a requirement for archaeological control and potential investigation on any other area within the Works that has not already been subjected to any assessment.

14.1.4 Drawing 9.2-A46-083-6110D in Appendix I outlines the areas within the Works which shall be carried out under archaeological control . The project archaeologist will be present on site for any topsoil strip and early excavations for material up to a 1m deep in the first instance.

14.1.5 The scheme archaeologist will be as listed in Table 3 of this document.

14.1.6 The Principal Contractor shall provide no less than five working days notice of the plan to carry out topsoil strip/excavation works in each of the locations identified on Drawing 9.2-A46-083-60. This is to allow sufficient time for the scheme



(CEMP)


archaeologist to make arrangments to attend site.

14.1.7 Before any excavation works take place, the scheme archaeologist will prepare a Written Scheme of Investigation (WSI) and submit it for approval by the Planning Archaeologist. The WSI should include the following information:

i. A description of the proposed methods of excavation and recording system;

ii. An explanation of the sampling strategies to be used;

iii. A project timetable for the work on site, including numbers of staff and machines (and for post excavation work, including staff numbers and specialist sub-Principal Contractors); and

iv. Any significant variations to the proposal by the Planning Archaeologist.

14.1.8 The areas will be stripped under the supervision of the scheme archaeologist up to a depth of circa 1.0m initially. The Principal Contractor will use a toothless ditching bucket to undertake the excavation and will work in spits based on the direction of the archaeologist. Excavation will continue until the top of any archaeological remains are reached, or the geological natural ground is encountered or the required dig level – whichever is first. The scheme archaeologist will make the assessment on site as to the point where excavation ceases.

14.1.9 If no archaeological features are found, the scheme archaeologist will record this and work shall continue. No excavation shall continue until the scheme archaeologist has reviewed, documented everything they require and confirmed that it can proceed.

14.1.10 If archaeological features are discovered, excavation shall be halted and time will be allowed in the programme for the scheme archaeologist (with assistance from other archaeologists as required) to excavate and record the features exposed. This may require additional excavation to clarify the character or extent of any archaeological feature exposed.

14.1.11 The scheme archaeologist will have the authority to halt any excavation works if necessary on the identification of possible areas of archaeological interest. Excavation work shall not recommence until the scheme archaeologist has documented what they require and then confirmed it can proceed.

14.1.12 Any human remains which are encountered must initially be left in situ until confirmed by the scheme archaeologist who will consult with the Planning Archaeologist as required.

14.1.13 Any areas of exposed archaeological remains will not be available for any form of construction work or for plant/vehicle crossing until permission is granted by the Planning Archaeologist. The scheme archaeologist will arrange for all necessary information to be provided to the Planning Archaeologist to enable that permission to be granted.

15. CONSTRUCTION LIGHTING

15.1.1 In determining the lighting arrangement on site, consideration will be given to residents and other environmental sensitive receptors that may experience a nuisance by light. Where appropriate, measures will be implemented to reduce obtrusive light.



(CEMP)


15.1.2 Where possible, a daylight only construction schedule will be adopted to minimise adverse lighting. It is unavoidable that construction work may require work during the hours of darkness in consideration of shorter daylight availability during winter months.

15.1.3 Where appropriate the following measures will be adopted for implementation:

i. Dim or switch off lights (including flashing beacons) where it is safe to do so

ii. Use specifically designed equipment

iii. Position lights sensibly and pointing away from boundary edges, residents and other environmental sensitive receptors.

15.1.4 Habitats on site including the linear scrub/trees and hedgerows on both phases are suitable for commuting and foraging bats. Further information on lighting and ecology can be found in the E-CEMP.

15.1.5 No night working is to be undertaken with working hours restricted to 1900 and 0700, as approved by the Overseeing Organisation. Should the use of lighting be required during these hours, (due to reduced daylight during winter and spring months), all lighting equipment will be directed away from habitats of value to faunal species such as trees, hedgerows and watercourses.

16. ECOLOGY

16.1.1 All matters pertaining to ecology are contained in the Ecological – Construction Environmental Management Plan (E-CEMP) which is contained in Appendix B.

16.1.2 Detailed habitat management descriptions for retained habitats and ecological enhancement measures are proposed via the production of a Landscape and Ecological Management Plan (LEMP), which is contained in Appendix J. The procedures for the LEMP will largely apply after the construction works have concluded and the landscape maintenance is underway.

17. GEOLOGY, SOILS AND CONTAMINATED GROUND

17.1.1 The permanent Works are to be constructed on a granular core of Class 1 acceptable material laid to a slope gradient averaging 1 in 2.5. Site won materials will be incorporated into the works providing that the necessary grading and materials specifications are met.

17.1.2 No contaminated ground was encountered during the ground investigation works and so is not anticipated to be discovered during routine earthworks operations. Should contaminated ground be detected, the procedure for dealing with it is outlined in Part 4.

17.1.3 The area around Finham Brook has been identified as having the presence of Himalayan Balsam. The design includes for a strategy for dealing with this plant in order to prevent its spread. This is outlined in more detail in the next section.

17.2 Treatment of Himalayan Balsam

17.2.1 The approximate extent of the Himalayan Balsam that is known is shown on drawing 9.2-A46-083-190 contained in Appendix C. It is not known the depths of soil that the plant spores may contaminate but the working assumption is that the



(CEMP)


top 500mm will be affected.

Finham Brook Flood Compensation Area

17.2.2 The Works requires the creation of a new permanent flood area to compensate for the construction of Westley Bridge. The work consists of reducing the existing ground level down to a lower level by removing some material from the area.

17.2.3 The strategy for addressing the Himalayan Balsam is as follows:

i. The top 500mm of material (assumed topsoil) will be excavated with care and under archaeological control and stored within the site area with appropriate measures in place to prevent the spread of the seeds. Colas SIAC are aware about the risks related to Himalayan Balsam and will make sure that all RAMS related to the works that will take place in the area(s) affected by Himalayan Balsam will outline the requirements of the Environment Agency Code of Practice.

ii. The remaining earth will then be removed down to the final required levels plus a further 500mm using conventional excavation techniques and bearing in mind the requirements of working near a watercourse outlined in the E-CEMP.

iii. All excavated earth will then be removed from the area. The topsoil containing the Himalayan Balsam seeds will then be reinstated to the final finished levels.

iv. All the RAMS will be approved by Colas SIAC and WCC before works start. During the performance of the works, visual inspections will be carried out by Colas SIAC to control the excavation, ensure that the topsoil contaminated with Himalayan balsam seeds remains on site and doesn’t enter into Finham Brook and control any other requirements stated in the RAMS.

Construction of New Westley Bridge

17.2.4 The construction of the new bridge will be within an area containing Himalayan Balsam. The proposed strategy for addressing the Himalayan Balsam in this area is as follows:

i. As outlined in the CPP, Colas SIAC will carry out a visual inspection during the pre-construction stage to determine the geographical area of Himalayan Balsam that is likely to be affected by bridge construction works.

ii. A method statement will be submitted to WCC and approved by WCC and the Environment Agency before the works related to the construction of the new Westley bridge start.

iii. As outlined in the project CPP, a method statement will be produced, stating that the top 500mm layer of soil (where the Hymalayan Balsam is present as seeds) will be excavated for the bridge works will be buried underneath a mound in the centre of the Dalehouse Lane roundabout. If there is insufficient room within the Dalehouse Lane mound for the aforementioned storage method, the remaining material will be safely removed from site in accordance with the Environmental Protection Act Sections 33 and 34.

17.3 Suitability of Ground Materials

17.3.1 All soil materials that are to be used on site (whether that is reuse of existing



(CEMP)


materials won from site or material imported into site), will be assessed for whether or not it is environmentally acceptable.

17.3.2 The first stage of this assessment will be to determine whether the material poses a risk in terms of polluting sensitive controlled waters and/or a risk in terms of harm to human health or the environment.

Polluting Sensitive Controlled Waters

17.3.3 During planning of the earthworks operations, the Principal Contractor will make an assessment of where on Site the potentially sensitive controlled waters are located. A ‘controlled water sensitive area’ is defined as:

i. Any area within 500m of a surface water body;

ii. In an area underlain by an aquifer designated as any of the following:

• Principal or Secondary A aquifer;

• Having intermediate or high aquifer vulnerability;

• A groundwater Source Protection Zone – total catchment (for a potable extraction); or

• Groundwater (Drinking Water) Safeguard Zone

17.3.4 The ground investigation works identified that the Site lies within 500m of a

surface water body (Finham Brook) and is in Zone 3 of a source protection zone. It was also noted that the bedrock is a Principal aquifer and some of the superficial deposits are Secondary A aquifers. Therefore, the entire site is classed as a controlled water sensitive area. A copy of the groundwater source protection zone is shown in Ground Investigation Report produced by WSP for WCC.

17.3.5 As a result of this, all material to be used will be chemically tested to demonstrate suitability for use. It will be tested at a frequency of one sample per 500m3 (subject to a minimum of three for each material stream from any distinct source). The samples will be submitted for soil leachability analysis to UKAS/MCERTS accredited laboratories. The SHEQ Manager will be responsible for ensuring this testing is carried out.

17.3.6 The samples will not exceed the Limiting Values as set out in Table 6 or else the material will not be used and an alternative compliant material sourced. The Limiting Values have been set in order to protect surface water quality and are based on available environmental quality standards.

Harm to Human Health and the Environment

17.3.7 As well as making an assessment to potential pollution of sensitive waters, all material must be tested to ensure it does not have the potential to cause harm to human health and other flora and fauna.

17.3.8 Similarly to the pollution assessment, all material to be used will be chemically tested to demonstrate suitability for use. It will be tested at a frequency of one sample per 500m3 (subject to a minimum of three for each material stream from any distinct source). The samples will be submitted for soil leachability analysis to UKAS/MCERTS accredited laboratories. The SHEQ Manager will be responsible for ensuring this testing is carried out.

17.3.9 The samples will not exceed the Limiting Values as set out in Tables 7 and 8 or else the material will not be used and either:

i. an alternative compliant material sourced; and/or

ii. a programme of treatment considered and applied which is then re-assessed for its suitability.

19.1 Protection of Existing Trees

19.1.1 There are numerous trees that are required to be protected for the duration of the works. Prior to works commencing in the area of the trees, and in accordance with planning condition No12, tree protection measures shall be put in place to prevent the trees being damaged during the construction of the works. The measures to be applied will be in accordance with the Tree Protection Plan (Appendix K).

19.1.2 The Construction Project Manager is to arrange for the weekly inspection of the tree protection fencing. These inspections are to be documented to evidence the ongoing surveillance and the records kept on file.

19.1.3 Should the fencing be found to be damaged in any way, the Construction Project Manager will:

i. Immediately stop works in the area;

ii. Arrange for remedial works to be carried out to the fencing;

iii. Investigate the reason for the damage to prevent re-occurrence; and

iv. Arrange for inspection of the tree and, where required, arrange for a trained arboriculturalist to carry out appropriate measures to minimise the impact on the tree

19.1.4 After any remedial measures to the tree have been undertaken, the Construction Project Manager will recommence the programme of weekly inspections which will now include a review of the mitigation measures undertaken.



(CEMP)


19.2 Landscaping Installation and Maintenance

19.2.1 A Site specific Method Statement and Risk Assessment for this activity will be prepared by Colas/SIAC before the works starts and a copy kept on the site file.

20. NOISE AND VIBRATION

20.1.1 Noise and vibration nuisances are controlled under the Environmental Protection Act 1990 as it has the potential to affect human health and habitats within and adjacent to the Site.

20.1.2 Noise and vibration shall be managed according to the best practicable means. The following mitigation measures will be implemented by the Contractor at all times to minimise noise and vibration generated from Site activities and disruption to any sensitive receptors:

i. Erecting noise protecting hoarding/sheeting to any boundaries adjacent to a receptor as outlined by the Ecologist or consider the use of constructing noise mitigation bunds;

ii. Control vehicle (especially lorry) movements in and around areas adjacent to receptors as well as ensuring vehicles are not stood with engines idling in the same areas;

iii. All plant, equipment and machinery used on site (including vehicular traffic), shall be designed and maintained to reduce noise levels to a minimum in order to meet the requirements of relevant EU directives and UK Statutory Instruments that limit noise emissions from construction plant, such as: Council Directive 79/113/EEC, Council Directive 86/662/EEC, Council Directive 86/662/EEC, Council Directive 95/27/EC and the Construction Plant and Equipment (Harmonisation of Noise Emission Standards) Regulations, 1988 SI 361;

iv. All plant equipment and machinery used on site, including vehicular traffic to and from the site, which is capable of being fitted with the appropriate silencers, baffles, cladding and rubber linings will be so fitted and maintained;

v. All plant will be sited so that the noise impact at nearby noise sensitive properties is minimized and will be switched off when not in use;

vi. Regular maintenance of plant in accordance with manufactures instructions;

vii. Noise and vibration monitoring on the Site, where necessary, which will assist in controlling levels at sensitive receptors. This will particularly apply when changes in processes are required for whatever reason; and

viii. Delivery vehicles will not be permitted to arrive on site before 07:30 or after 18:30 Monday to Friday, before 08:00 or after 13:00 on Saturday or at any time on Sundays or Public Holidays nor will they be permitted to wait on the Public Highways outside of these timescales. Care will be taken when unloading vehicles to minimise noise. Delivery vehicles will be routed to minimise disturbance to local residents. Delivery vehicles will be prohibited from waiting within the site with their engines running;

ix. Working hours would be restricted to the hours indicated in Table 10 below.



(CEMP)


20.1.3 Noise levels shall be monitored in an around the boundaries of the site adjacent to sensitive receptor sites. The ambient noise level (Leq) from all sources when measured 2.0m above the ground and 1.0m from the boundary of any receptor site shall either not exceed the appropriate level outlined in Table 9 or not exceed by more than 3dB(A), the existing ambient noise level (Leq).

20.1.4 Colas SIAC subcontractor will undertake background noise surveys at various times and locations around the Site before the main works start to establish the normal noise levels and monitor when the works’ performance exceed them.

20.1.5 When comparing the noise levels during the construction against the ambient level (Leq), the monitoring shall take place at the same location and over the same period as that which was used to determine the ambient level (Leq).

20.1.6 Should the construction noise levels consistently exceed those of the ambient levels (Leq), all construction work in the area shall cease until the source of the high noise level can be determined and rectified. Where necessary, the Contractor shall amend the method of working to minimise the impact of the noise operations.

20.1.7 Any such change to the working methodology or other noise mitigation procedures shall be recorded in the CEMP and distributed to the site staff by means of a Toolbox Talk.

Table 9: Schedule of Maximum Noise Levels Permitted

(CEMP)


21. WASTE

21.1.1 The Site will operate a Site Waste Management Plan (SWMP), broadly in line with the Site Waste Management Plan Regulations 2008 and required by the Employer under the Contract under Clause 175AR.

21.1.2 The SWMP is contained in Appendix E of this document. It shall be maintained and regularly reviewed by the Construction Project Manager and will be made available to all personnel on site as appropriate.

21.1.3 The SWMP will also be made available for inspection at all times by the Employer or any key stakeholder (e.g. Highways England) where required.

21.1.4 In accordance with Clause 174AR of the Contract, the quantities of recycled and secondary materials shall be recorded in an excel spreadsheet similar to the one presented in Appendix F.

21.1.5 For waste management details, please refer to the Colas Waste Management document presented in Appendix G and the draft shown in the Site Setup contained in the CPP.

21.1.6 All data sheets contained within the SWMP (documenting the usage and destination of all waste materials) shall be supplied to the Employer (and where necessary Highways England) within one month of completion of the Works.

22. WATER ENVIRONMENT

22.1.1 The majority of the Works lie within the natural catchment of Finham Brook. Only the most south-eastern part of Stoneleigh Road is located within the natural catchment of the River Sowe. The locations of the two watercourses in relation to the scheme are shown on the River Network Location Plan, drawing number drawing 9.2-A46-083-079 in Appendix D.

22.1.2 Both Finham Brook and the River Sowe are classified by the Environment Agency as having overall Moderate status (as per the 2015 cycle).

22.1.3 The drainage strategy for the Works is to reuse existing drainage outfalls to Finham Brook and the existing drainage system on Stoneleigh Road that ultimately ends in the River Sowe. Where necessary, treatment and attenuation of the permanent water has been encompassed into the design through the use of soakaways, swale and attenuation ponds.

22.1.4 During construction, water pollution has the potential to significantly alter environmental conditions on Site which can subsequently impact the viability of ecological habitats in those areas affected as well as cause a risk to human health. In particular, pollutants which can enter soil and water can change the chemical composition of growing substrates and water bodies which can damage the biodiversity of the watercourse.

22.1.5 It is considered that certain construction elements of the Works have the potential to contravene the Salmond and Freshwaters Fishery Act 1975 i.e. cause a pollution or silt incident associated with Finham Brook, which is classified as a Salmonid River. As such, in addition to those mitigation measures with regards to air, water and soil pollution as detailed elsewhere in the CEMP, further mitigation procedures will be applied during construction activities.



(CEMP)


Works Affecting Finham Brook

22.1.6 Works around Finham Brook will be subject to a defined method which as been approved by the Environment Agency (EA). A copy of that method and Environmental permit is contained in Appendix A of the E-CEMP. It is expected that there will be minimal amount of impact on biodiversity in the brook. The Works shall be carried out in accordance with the E-CEMP recommendations which describe a precautionary approach to the construction activities.

22.1.7 Water and soil pollution have the potential to significantly alter environmental conditions on Site which can subsequently impact the viability of habitats in those areas affected. In particular, pollutants that enter soil and water can change the chemical composition of growing substrates and water bodies which can significantly impact species growth, composition and diversity.

22.1.8 When working within 10m of Finham Brook, special considerations and working methods will be adopted. These were outlined in the Technical Note for Salmonid Rivers and are reproduced below:

i. No groundworks will occur during wet of forecasted to be wet conditions within the subsequent 24 hours that are within:

10m of the brook edge;

5m from the top of a slope that leads to the brook where precipitation may cause silt to be washed into the brook;

5m of a ditch, channel or drain that leads to the brook.

ii. Unless or until the following preventative measures have been put into place at an appropriate time:

Anti-pollution barriers are placed to prevent silt from entering the brook or a watercourse/pathway leading to the brook; and

Soft ground is compacted or covered to prevent silt from entering the brook or watercourse/pathway leading to the brook.

22.1.9 The Principal Contractor will ensure that the site is registered with the Environment Agency’s (EA) Floodline Warnings Direct Service, so that any flood warning information issued by the EA is automatically received.

22.1.10 As required by the Environmental Permit, the Principal Contractor will ensure the EA is notified of the intention to carry out works no more than 7 working days before its commencement. The EA will also be notified no more than 7 days after the works have been completed.

22.1.11 Under no circumstances shall waste chemicals, fuels, silt or sediments be discharged or allowed to discharge into the Finham Brook watercourse.

22.1.12 Prior to works taking place around Finham Brook, silt trap devices, booms and blankets will be installed immediately downstream of the works to intercept suspended sediment, concrete and any accidental spillages. In addition, spill kits and mats will be readily available alongside the works which will be used to mop up or contain any material/liquid in the event of a spillage.

22.1.13 A suitable number of spill kits shall be kept on the Site in the vicinity of the Works in progress, which as a minimum shall contain absorbent granules, sand bags and



(CEMP)


drain covers. Absorbent pads and booms shall preferably be used instead of granules and sand bags where possible. Used spill kits shall be disposed of appropriately, for example as hazardous waste, where relevant and the appropriate environmental regulator immediately notified by the Principal Contractor.

22.1.14 During the initial phases of the Works, pre-earthworks drainage with inline silt protection is to be established. Where inline silt protection measures are not possible, silt busters or similar are to be employed to de-silt surface water.

22.1.15 An emergency response plan with the EA’s contact details will be in place in the event of a major incident/spillage and/or flooding. All workers will be made aware of the emergency response plan and boards erected detailing the emergency response procedure with contact details of site supervisor, general foreman etc. This site procedure will be located adjacent at the work face, site offices and designated phone areas.

22.1.16 All staff and workforce shall be made aware of the procedures and trained in the use of spill equipment and how to manage and dispose of waste materials legally. As part of the communication processes outlined in this CEMP any Induction and/or Toolbox talk shall cover these specific mitigation measures required to be implemented for the Salmonid species.

Flooding Contingency Plans

22.1.17 In order to mitigate any flood situations, close consultation will be maintained with WCC and the EA using up to date weather forecasts and flood alerts, which will give some warning and allow the Principal Contractor to prepare for a flood event through the MET Office forecasts.

22.1.18 The weather forecast for the week ahead will be regularly checked and if it predicts that a flood event is likely then measures will be taken to remove any hazardous materials from the site and store them in a safe location so that if the site floods no pollutants contaminate Finham Brook, any other drainage or the groundwater.

22.1.19 If there is an enforced shutdown for any other reason, hazardous material will again be removed from site and stored in a safe location.

Discharging Water

22.1.20 Before any work commences in either the Works, or a specific area of the Works in accordance with the construction phasing, the Construction Project Manager will arrange for an inspection of the immediate area in order to ascertain the likely water discharge points. This inspection will consider whether discharge of water is likely to impact flooding, any ecology or impact human health. Any such point identified will be documented along with the reasons for selection.

22.1.21 Once identified, the discharge point will be written into the Method Statement for the specific construction operations to which they apply. The Construction Project Manager will then ensure that the method documented will be applied while the works are undertaken.

23. WATER CONSUMPTION

23.1.1 Effective construction management can deliver major savings in water use and the associated costs of energy, water supply and wastewater treatment. This can be achieved without compromising the performance and user acceptability of the



(CEMP)


project.

23.1.2 Typically, the use of water will take place in the following areas:

i. Dust suppression for construction operations and at stockpiles of soil;

ii. Cleaning for vehicles and across the site;

iii. Domestic and Welfare facilities including toilets, drinking water and food preparation areas; and

iv. As part of construction operations, e.g. mortar or cement mixing.

23.1.3 The project will where appropriate utilize the following examples of best practice, or equivalent:

i. Enable monitoring of water use: e.g. install meters which are easy to read; ensure all areas of site water consumption are quantified; consider splitting welfare and “site-based” water consumption; record site water consumption on a regular basis for review at project progress meetings; and regular meter readings should be taken from all meters, sub-meters and metered standpipes (weekly is recommended);

ii. Reduce the risk of uncontrolled water use: e.g. sensor-actuated devices (such as infra-red actuated taps and occupancy sensors);

iii. Minimise the risk of leakage: leak detection equipment (including pulsed meters for regular monitoring); ensure valves and overflows are visible for early detection of water loss and easy to access for maintenance; and

iv. Influence user behaviour: Creating a culture that changes attitude and behaviour to accepting ownership of water efficiency is fundamental to improving the use of water in an efficient manner.

23.1.4 Good housekeeping (e.g. reporting/repairing leaks, turning off taps which are not in use, and generally using water in an efficient manner) can assist the site reduce its overall water use.

23.1.5 The provision of information on appropriate use of fittings and appliances; raising awareness of the costs and environmental importance of water efficiency will be conducted via Tool Box Talks. The talks will also cover guidance on processes for identifying and reporting water leakage / poorly-performing fittings and the method for providing feedback.

Works Affecting Finham Brook

23.1.6 Works within Finham Brook will be subject to a defined method which has been Soil Pollution Control.

23.1.7 The area of the works has been kept as small as possible to ensure there is not significant impact on the adjacent habitats or wildlife. The works only extend a small distance away from the construction activities.

23.1.8 All waste material will be carefully excavated and transported on site. Storage of materials at the work face will be limited and hence materials will be distributed as they arise.



(CEMP)


Flooding Contingency Plans

23.1.9 In order to mitigate any flood situations, close consultation will be maintained with WCC and the EA using up to date weather forecasts and flood alerts, which will give some warning and allow the Principal Contractor to prepare for a flood event through the MET Office forecasts.

23.1.10 The weather forecast for the week ahead will be regularly checked and if it predicts that a flood event is likely then measures will be taken to remove any hazardous materials from the site and store them in a safe location so that if the site floods no pollutants contaminate Finham Brook, any other drainage or the groundwater.

23.1.11 If there is an enforced shutdown for any other reason, hazardous material will again be removed from site and stored in a safe location.

24. POLLUTION PREVENTION AND HAZARDOUS MATERIAL STORAGE

24.1.1 Chemicals and hazardous materials such as fuels and lubricants are to be stored on site during the construction of the project. Such materials include (but are not limited to) the following:

i. Fuels

ii. Oils

iii. Lubricants

iv. Paint and Coating

v. Adhesives and resins

vi. Solvents

vii. Compressed gases

viii. Cements and binders

24.1.2 The Site Setup presentend in the CPP shows the storage location of fuelling facilities and storage areas for chemicals and materials.

24.1.3 All materials and liquids that have the potential to pollute any water body shall be stored in COSHH stores. All necessary COSHH paperwork associated with any such material shall be made available on the COSHH register.

24.1.4 The detailed storage and handling procedures for hazardous materials will be contained within the COSHH Data Sheet, as briefed out to Site personnel.

24.1.5 The Pollution Prevention procedures shall be cascaded to the Site Operation Teams via frequent Toollbox Talks. A Toolbox Talk Register shall be maintained and recorded in the Principal Contractor’s electronic system.

24.1.6 All oil or other potential contaminants stored on the site will be controlled in accordance with the Control of Substances Hazardous to Health Regulations (COSHH) (HSE, 2002). These will be isolated, placed on drip trays or bunded such that no oil or other contaminants could reach watercourses or groundwater.



(CEMP)


24.1.7 Storage of such materials will be located in a secure area, at least 10m away from any watercourses and 50m from any spring, well or borehole and watercourse with any flood zones.

24.1.8 All static plant such as generators will contain appropriate secondary containment or be placed on drip trays at all times.

24.1.9 Relevant spill kits will be located at strategic locations and personnel trained in their use.

24.1.10 Cement, concrete and grouts are highly alkaline and corrosive and could cause serious pollution to the ground and watercourses. The measures to prevent pollution from these substances is as detailed below:

i. Concrete mixed on site will be carried out on an impermeable designated area located at least 10m from any watercourse or surface water drain to reduce risk of run-off entering a watercourse;

ii. Surplus dry concrete and grout will be used elsewhere on site if suitable, or as inert rubble. Where this is not possible it will be disposed of off-site at a suitable facility and transported using a registered waste carrier;

iii. All equipment used for working with cement will be washed out in a designated washout area that had been specifically designed to contain wet concrete/ wash water. The concrete washout area will be located well away from any watercourses, drain or other elements sensitive to contamination;

iv. Wash waters will be stored to allow solids to settle out and will be recirculated to minimise the risk of pollution and reduce water usage. Contaminated wash water will be collected for authorised disposal off-site;

v. Concrete mixing and delivery lorries will return to the batching plant for washout; and

vi. Silt fences will be set up at the edge of the construction site near watercourses to protect water quality. Mitigation such as straw bales will be on standby to prevent sediment entering the water channels.

25. MONITORING AND AMENDMENTS TO THE CEMP

25.1.1 The Construction Project Manager shall arrange for a coordinate a periodic CEMP Review to assess whether the procedures and processes outlined in the CEMP are being operated effectively, are meeting the environmental requirements of the project and statutory legislation and, where necessary, recommending improvements. Where necessary, the Construction Project Manager shall appoint a delegated person(s) to undertake this review.

25.1.2 The review shall be required by the timescales of the project but shall not be greater than quarterly. The reviewer shall gather, collate, analyse and interpret the following input information:

i. The status of any actions from previous CEMP Reviews;

ii. The status of any actions from any other audits on the CEMP or its activities (whether external or internal);

iii. Appropriateness and effectiveness of the mechanisms for communicating



(CEMP)


the contents of the CEMP to all personnel working on site;

iv. Trends in the application of the procedures and requirements of the CEMP when used to construct the Works (by all parties that are required to adhere to it e.g. Sub-Principal Contractors);

v. Assessing whether there has been any change to on-site conditions that may affect the restrictions and/or procedures outlined in the CEMP;

vi. Reviewing any environmental incidents (and any investigation thereof) that may have occurred since the last review; and

vii. Considering where the CEMP feeds into other control documentation (e.g. quality procedures, risk and method statements) and assessing whether these documents are still fit for purpose or are required to be revised.

25.1.3 Once the review is complete, a report shall be produced that will be issued to the Employer and kept on file if further scrutiny is required. The report will be tailored to suit the findings of the assessment, but will likely cover such things as:

i. Recommendations/actions for any issue identified. This may include changes to the actions/procedures listed in the CEMP (or any associated documents such as the E-CEMP), in which case, the CEMP or other required document will then be updated;

ii. Statements relating to the suitability and effectiveness of the CEMP and physical application of the CEMP’s principles on site;

iii. Statements relating to the effectiveness of any corrective actions employed from previous audits, management reviews or response to an environmental incident.

25.1.4 Where the outcome of any review requires the update of the CEMP, the document shall be amended as required and then formally issued to supersede the previous revision in line with the project’s document control procedures.

26. INTERNAL COMMUNICATION & TRAINING

26.1.1 “Internal” communication shall cover communications between individuals and parties working on the Site or are affiliated to the Site as part of the wider project team.

26.1.2 The CEMP will be distributed to the project team, including Sub-Contractors, to ensure that the environmental requirements are communicated effectively. Key activities and environmentally sensitive operations will also be briefed to staff through the Site Induction and regular Toolbox Talks. An environmental register must be signed and updated to confirm toolbox talks, training and weekly meetings by the environmental team.

28. ENVIRONMENTAL ACTIONS AND COMMITMENTS

28.1.1 An Environmental Actions and Commitments Register has been developed for the scheme which is contained in Appendix L.


PART 4 – REACTIVE MEASURES – INCIDENT RESPONSE PROCEDURES


29. INCIDENT RESPONSE – GENERAL

29.1.1 Any and all environmental incidents (including ecological incidents and those that could lead to regulatory enforcement, public complaint or media attention), will be immediately reported to the Construction Project Manager who will immediately report the incident to the Environment Agency Incident Hotline – 0800 80 70 60. Following this, any other relevant individuals and organisations shall also be informed.

29.1 Definitions

29.1.1 An environmental incident (or event) can be defined as an uncontrolled or unplanned event which impacts, or has the potential to impact, on the environment, event types include:

i. Spillage – unplanned loss of substances with potential for environmental damage, impacting on land and / or water dependent on the location, drainage, etc.

ii. Emissions to air – uncontrolled or unplanned emission of particulates, smoke, odours, etc which cause a nuisance and / or environmental hazard.

iii. Breach of legislation – breaches identified by a regulatory authority or internally, for example during monitoring or inspection routines.

iv. Complaints – from the public or any third party, often relating to a nuisance issue such as dust, fumes or noise.

29.1.2 Further guidance on incident classification can be found in the appropriate section below.

29.2 Responsibilities

29.2.1 All employees shall be responsible for minimising the impact their activity has on the environment. In the event of an incident, all employees have a responsibility to react immediately to minimise the effects with due regard for the safety of themselves and others.

29.2.2 Activity managers shall be responsible for ensuring adequate emergency actions are implemented to minimise the impact of an environmental incident and thereafter undertake the necessary investigation and implement effective corrective actions to reduce the likelihood of recurrence.

29.3 Immediate Impact Control Measures – All Incide nts

29.3.1 The first priority with all environmental incidents shall be to minimise the impact on the environment by initiating immediate control and containment actions wherever possible. The type of actions required will be dependent on the incident, but the primary response must be to Stop the Source and Contain the Released Material where relevant.

29.4 Reporting

29.4.1 All environmental incidents must be reported using the Colas AIRSweb HSEQ reporting system. Events which are classified as a Near Miss may be recorded on AIRSweb or the Colas Near Miss Reporting Card system. However when the card system is used, the additional corrective actions may be requested by the SHEQ Manager, additional actions will be raised and managed using the AIRSweb system.


29.4.2 Significant events, including breaches of operating permits must also be reported to the relevant Enforcing Authority e.g. Environment Agency or SEPA for spillages entering surface water drains or a controlled water and Local Authorities for events relating to Permitted Processes such as asphalt plants. An overview of reporting requirements can be found on the Colas Incident Reporting Guide – copies of which are available from the SHEQ Manager.

29.4.3 Copies of correspondence from third parties should also be uploaded to AIRSweb and attached to the incident report, together with photographs, maps, plans, etc.

29.4.4 When reporting an environmental incident or event, the following points should be detailed (as relevant):

i. The type of incident e.g. spillage, emissions to air, etc

ii. Type and quantity of material lost

iii. Name, address and contact details of complaina nt

iv. Notifications made to Enforcing Authority, name , time, etc

v. Immediate actions taken to minimise pollution ri sk

vi. Weather conditions

29.4.5 All environmental incidents and near misses must be reported within 24hrs using either the AIRSweb system or Near Miss Reporting Cards. AIRSweb allows for just the initial event details to be recorded with corrective actions to be added following the investigation.

29.5 Incident Classification

29.5.1 Environmental events are classified in accordance with the following guidance:

i. Incident – this classification should be used wherever an event has an environmental impact, this includes but is not limited to:

− release of material to an external drainage system or controlled water (river, stream, lake, groundwaters, coastal water, etc)

− release of material to ground where material infiltrates substrate. Spillages that are completely contained and cleared with no impact on the ground below shall be recorded as ‘near miss’

− any breach of operating permits e.g. emissions to air, stack test failure on asphalt plant, exceeding blast vibration limits during quarry operations

− noise, dust or nuisance complaints from third parties or regulators where Colas SIAC are found liable


ii. Near Miss – shall be used for minor events where the occurrence has the potential for environmental impact but early identification and/or actions have prevented an actual incident e.g. spillage contained within bund or hardstanding

iii. Reporting Purposes Only – used for events that Colas SIAC does not have direct control or responsibility over or for unjustified complaints from Third Parties, etc.

29.6 Investigation and Corrective Action

29.6.1 Investigation of environmental incidents shall be conducted by the activity manager, the depth of investigation shall be commensurate with the scale of the incident; details of the investigation shall be documented on the Colas AIRSweb HSEQ Reporting system with supporting information uploaded as required.

29.6.2 Investigations should conclude the following:

i. Exact details / facts of event

ii. Root cause of event

29.6.3 Corrective actions need to be commensurate with the severity of the incident and the associated pollution risk; actions may include but not be limited to:

i. Training / retraining of personnel

ii. Revision and amendment of EMS and local environ mental procedures

iii. Revision and amendment of maintenance and / or calibration routines

iv. Amendment / implementation of monitoring routin es

v. Review of relevant Environmental Risk Assessment s and Controls

29.7 Incident Review

29.7.1 Environmental incidents not classified as Near Miss or Reporting Purposes only shall be counted towards the Company’s Environmental Incident Frequency Rate (EIFR). This rate is calculated using the same methodology as Safety LTIFR.

29.7.2 Incident analysis and statistics shall also be produced each month by Safety Services and distributed to Colas SIAC managers; these reports shall also be published on the Colas EMS accessible to all computer users through the Company’s intranet.

29.7.3 Environmental incidents and associated corrective actions shall be reviewed as part of the EMS Management Review Process.


30. INCIDENT RESPONSE - SPILLAGE

30.1.1 The most common type of incident requiring immediate action are spillages; the greatest risk posed to the environment is the release of substances into controlled waters (rivers, streams, lakes, etc). It should be noted that most surface water drainage systems will discharge to a watercourse and therefore spillages must be prevented from entering surface (storm) water drainage systems.

30.1.2 Controlled waters also include groundwaters such as aquifers, spillages can result in pollutants seeping through soil and contaminating groundwaters which are often used as a source of drinking water.

30.1.3 Although spillage incidents are normally associated with liquids, loss of dry materials can be an issue if they are washed away by rainwater.

30.1.4 The basic principles of Spill Management shall be communicated to all operational personnel, particularly where a spill risk has been identified; this may be supplemented by a site or activity-specific spill procedure in which personnel shall be trained.

30.1.5 Fire water run-off can also pose a significant risk to controlled waters and wherever possible should be contained for example through use of pollution control valves or bunding.

30.1.6 The Spillage Procedure shall be as outlined on the flow charts on the following two pages.


31. INCIDENT RESPONSE – EMISSIONS TO AIR

31.1.1 Incidents involving emissions to air may require immediate action for example loss of materials (e.g. fines) during transfers or failure of dust control systems. The first priority will be to stop the activity i.e. cease material transfer or shut-down plant to prevent further release.

31.1.2 Emission incidents will also include release of odours and fumes, particularly relevant to manufacturing plants sited near to residential or commercial premises, in which case the incident may be identified through a complaint from a Third Party e.g. Enforcing Authority, neighbouring business or residential property. This type of incident may require detailed investigation unless the source is immediately obvious e.g. following a plant malfunction.

32. INCIDENT RESPONSE – CONTAMINATED GROUND

32.1.1 All ground investigation carried out on the site to date have highlighted that there are no areas of contamination identified. The exception of this is Himalayan Balsam but there is an active measure for dealing with this outlined in Part 3.

32.1.2 Despite this, a working method which promotes vigilance will be adopted on the project with respect to encountering contaminated material. Such materials may be (but not limited to) the following:

i. Visible suspected asbestos;

ii. Material with strong or obvious odours;

iii. Material with bright or unnatural colouring;

iv. Encountering unexpected liquids or perched groundwater.

Encountering Contaminated Material

32.1.3 Should potentially unacceptable or contaminated land be encountered, the Principal Contractor shall notify the Employer immediately with the aim of establishing a watching brief on the area by a suitable qualified and experienced contaminated land professional who shall be in attendance.

32.1.4 Condition 5 of the Planning Approval requires the County Planning Authority to be notified immediately in writing if contaminated material is encountered during the works. The Employer shall notify the County Planning Authority based on information provided by the Principal Contractor.

32.1.5 Upon identification, the material will be capped and left in situ (where soil porosity is low enough not to present a risk of migration of contaminants) The affected area will be fenced off and signs posted to warn of the presence of the contaminated material. All personnel on site will be made aware of the special arrangements regarding the suspected material.

32.1.6 If the material presents an immediate Health and Safety or Environmental hazard, it shall be carefully excavated and stockpiled separately from other arisings. Any such excavation would be under the supervision of the contaminated land professional.

32.1.7 Storage of any such material shall be within a secure area with contained drainage, provided with an impermeable base to prevent seepage of contaminated water and covered to prevent rainwater mobilising contaminants.


32.1.8 Once the immediate actions regarding the material have been undertaken (i.e. left in situ or else moved if it poses a H&S or Environmental risk), a detailed Method Statement and Risk Assessment for treatment of said material would cover such things as:

i. Keeping records on locations, extents, volumes, movements and any test results undertaken;

ii. Sampling and testing (including type and frequency) of the suspected material by suitably qualified and experienced professionals;

iii. Recording treatment of material (including removal and disposal arrangements if required);

iv. Handling and stockpiling of the material;

v. Management of environmental issues such as pollution of ground water and/or surface water or release of gases;

vi. Preventing cross contamination of the material on other aspects of the Site and/or surroundings;

vii. Health & Safety and Environmental practices when working with or near the material.

32.1.9 Any risk assessment or method statement will need to be submitted to the County Planning Authority in accordance with Condition 5 of the Planning Approval. No remedial work will take place until approval of the submitted documents is provided from the Planning Authority.

32.1.10 To derive the Method Statement, samples of the contaminated material shall be taken and analysed to determine the chemical constituents and an appropriate disposal method chosen. Determining the appropriate method of disposal would be carried out in consultation with the Environment Agency and the Employer. Any chemical testing undertaken on material samples shall be carried out by approved specialist laboratory that has UKAS accreditation and MCERTS accreditation for soils testing.

32.1.11 Unless otherwise agreed in writing by the Local Planning Authority, the approved Method Statement will be either fully implemented prior to the recommencement of construction or concurrently with construction and fully implemented prior to completion of construction and first use of any part of the site.

32.1.12 The investigation, assessment and disposal of any unacceptable or contaminated materials shall be undertaken in accordance with:

i. Control of Substances Hazardous to Health (COSHH) Regulations;

ii. CIRIA C733 Asbestos in soil and made ground: a guide to understanding and managing risks;

iii. CIRIA C765 Asbestos in soil and made ground good practice guide;

iv. If required – Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR);

32.1.13 Treatment shall not include for mixing/lending of contaminated material with other material in order to “reduce” the contamination levels unless specific permission has been applied for and granted by the Environment Agency, Local Health Authority and the Employer.


32.1.14 Once the Method Statement has been approved and its actions carried out on site, a verification report will be prepared by the Construction Project Manager and provided to the Employer. The Employer will then submit it to the County Planning Authority in order to comply with Condition 5 of the Planning Approval.

33. INCIDENT RESPONSE – WATER BODIES

33.1.1 If the weather forecast predicts that a flood event is likely then measures can be taken to remove any hazardous materials from site and store them in a safe location so that if the site floods no pollutants contaminate the watercourse. If there is an enforced shutdown, hazardous material will again be removed from site and stored in a safe location.

33.1.2 The following is a list of possible accident scenarios:

i. Hydraulic pipes on excavator burst with possible leak of hydraulic oil.

The risk is considered low. All hydraulic systems will be fitted with shut off valves that will restrict the amount of hydraulic oil that will escape during a pipe or coupling burst. Biodegradable hydraulic oil to be used and the site will have spill kits and drip trays that can be put in place in a few minutes. There is potential for oil to escape but these should be minimal and will be very carefully cleaned up using proprietary materials. All contaminated materials will be removed from site and disposed of in an appropriate way.

ii. Breakdown of excavator during excavation.

It is possible that an excavator could breakdown part way through the excavation for the earthworks and channels which if there is a flood could pollute the adjacent watercourses. However no work will be started if there is concern that a flood event is imminent and the machine is likely to be a standard machine that would be easily and quickly replaced.

iii. Fires.

It is considered that fires are a very low risk on this site where no flammable materials will be stored.

iv. Vandalism

v. The Construction Project Manager will ensure that the working area is securely fenced off to prevent unauthorised access. During non-working hours the site will be monitored with CCTV cameras and or security staff visiting.
