1Introduction

1.1Background, Aims and Objectives

1.1.1                          This document, the Outline Construction Environmental Management Plan (CEMP), contains the requirements and expectations of Ayre Offshore Wind Farm Limited (AOWFL) to manage the environmental and consenting requirements of the onshore elements of the Ayre Offshore Wind Farm (the ‘Project’). For ease of reference the onshore elements of the Project, landward of Mean Low Water Springs (MLWS), are referred to as the ‘Proposed Development’.  This outline is provided to support the Planning Permission in Principle application. The detailed CEMP will be developed by the appointed Principal Contractor based on the Schedule of Mitigation (document reference: TWP-AYR-RPS-OSC-RPT-00029) in the Environmental Impact Assessment (EIA) Report (TWP, 2025) and any conditions from the Planning Authority, The Highland Council (THC), stated in the Planning Permission. The CEMP would be submitted to THC for approval in consultation with Scottish Environment Protection Agency (SEPA), NatureScot and other relevant consultees as required.   

1.1.2                         The principal objective of this Outline CEMP is to provide information on how AOWFL (the Employer) intend to avoid (where possible), minimise and control adverse environmental impacts associated with the Proposed Development during Construction.

1.1.3                         This document also includes good practice as well as specific actions to be implemented following receipt of Planning Permission. The information contained within the CEMP will form part of the Principal Contractor’s Scope of Work. The methods and principles contained herein, as well as within referenced legislative instruments and published guidance documents, are adhered to by the Principal Contractor in developing the detailed design, construction and post operations. This will be completed under a Construction Phase Plan, and method statements and other plans relating to environmental management as required by the Contract.

1.1.4                        The Employer will provide the Principal Contractor with an electronic copy of the Outline CEMP which the Principal Contractor will develop into the detailed CEMP and will maintain for the duration of the works. The Employer will submit all relevant information as detailed in this document to the relevant authority, in this case THC. The Employer will provide the relevant authority with the relevant information according with the contract provisions. No works commence prior to the Employer’s and THC’s acceptance.

1.2Roles and Responsibilities

1.2.1                         The Employer (AOWFL) will be responsible for overall management and delivery of the Proposed Development. The Employer will appoint an appropriately competent Principal Contractor who will be responsible for the construction phase of the Proposed Development including any subcontractors.  They will plan, manage, monitor and coordinate the construction phase and be responsible for health and safety and environment. 

1.2.2                       The Principal Contractor will also be responsible for updating this Outline CEMP once design and construction plans have been finalised, and handing the detailed CEMP over to the Employer for monitoring during operation, as appropriate. The Principal Contractor will be required to delegate responsibilities to suitably experienced on site personnel within the key areas of the site and these will be responsible for implementation, reporting and monitoring of environment mitigation during the contract period.

1.2.3                       The Principal Contractor will provide or appoint competent and trained Environmental Representation (Site Environmental Representative) to undertake relevant environmental tasks as detailed in this Outline CEMP prior to, during and upon completion of the construction works. Some of the site supervision roles involved in the delivery of the CEMP which involve supervising, monitoring or checking the Principal Contractor’s Environmental Method Statements, Management Plans and working methods, may be appointed directly by the Employer e.g. Environmental Manager.

1.2.4                       A summary of key personnel and a summary of their anticipated responsibilities are provided in Table 1.1   Open ▸ . The key project roles will be developed with the Principal Contractor once appointed and adapted to meet Planning Permission requirements. 

1.2.5                       The Principal Contractor is required to keep a record of competent expert statements including contact details and lines of escalation for personnel involved in the implementation, reporting and monitoring of the environmental mitigation required through this Outline CEMP, including the organisations described in Table 1.1.

1.2.6                       The Principal Contractor demonstrates the competence of the Site Environmental Representative to the Employer via submission of relevant information (e.g. CV, accreditation/professional membership records) for acceptance prior to commencement of construction works.

1.2.7                       The Principal Contractor is responsible for obtaining all necessary consents, licences and permissions for their activities as required by current legislation governing the protection of the environment.

1.2.8                       A copy of the CEMP and related files and documents will be kept in the site offices for the duration of the site works and will be made available for review at any time.

1.2.9                       Upon completion of the construction works, the Principal Contractor will submit a complete electronic copy of the final set of information to the Employer for their records.

1.2.10                    Where the Principal Contractor has standard documents within their own company/corporate Environmental Management Plan which might cover a particular requirement of this CEMP, these will be inserted or cross referenced within the relevant Section of the detailed CEMP (produced following consent to include further commitments).

1.2.11                      A Checklist has been included in the CEMP providing a summary of the minimum information to be provided to the Employer pre-, during and post construction.

1.2.12                    The CEMP will contain a number of supporting plans to be developed with the Principal Contractor based on the mitigation requirements of the Onshore EIA and any future planning conditions from the Local Authority, THC. Any such Plans will be Annexed to the CEMP.

2Requirements

2.1Project Specifics (Constraints, Mitigation and Planning Conditions)

Schedule of Mitigation and Commitments Register

2.1.1                         A range of mitigation measures, designed to avoid or minimise significant environmental effects from the Proposed Development are detailed within the Onshore EIA Report and Schedule of Mitigation (document reference: TWP-AYR-RPS-OSC-RPT-00029) for the Proposed Development.

2.1.2                       Following receipt of Planning Permission, the Schedule of Mitigation will be updated and incorporated into the Commitments Register which will detail all mitigation measures referred to in the Onshore EIA Report, and additional documentation provided to and approved by THC. The Commitments Register will also include all Consent Conditions.

2.1.3                       The Principal Contractor will adopt and implement the measures in the Commitments Register.

2.1.4                       A copy of the Commitments Register will be provided in Annex A of this CEMP.

2.2Site Induction

Training and Toolbox Talks

2.2.1                       The Principal Contractor will ensure that all contractor employees, sub-contractors, suppliers, and other visitors to the site are made aware of the specific environmental issues relating to their work. Accordingly, environmental specific induction training will be prepared and presented to all categories of personnel working and visiting the site.

2.2.2                      As a minimum, the Principal Contractor provides inductees with the following information:

• Identification of specific environmental risks associated with the work to be undertaken on site by the inductee (e.g. exclusion zones, fuel handling, spill kit locations, sensitive habitats, drainage control/mitigation, spill control, silt pollution control, waste minimisation and recycling, reporting of environmental observations).
• Environmental Incident and Emergency Response Procedures (including specific communication requirements).

2.2.3                      The Principal Contractor provides a convenient sized copy of relevant environmental constraints mapping and written brief to all inductees showing sensitive areas, exclusion zones, wash out areas, watercourses, refuelling exclusion areas, location of skips, etc. The map shall be updated and re-issued as required. Any update will trigger a tool box talk, see below, to comment and stress on necessary change.

2.2.4                     The Principal Contractor submits a tool box talk schedule at least one week prior to commencement of works to the Employer’s Environmental Manager. The proposed schedule, to be considered as a live document, shall be consistent with the programme of works.

2.2.5                      Additional tool box talks shall be added as required based on circumstances such as unforeseen risks, repeated observation of bad practices, perceived lack of awareness, pollution event, etc.

2.2.6                     The Principal Contractor provides, as a minimum, one environmental related tool box talk on the above topics, along with any other environmental issues which arise on site. Additional tool box talks shall be added as required based on circumstances such as unforeseen risks, repeated observation of bad practices, perceived lack of awareness, pollution event, etc.

2.2.7                      Where necessary, the Principal Contractor requests the assistance of specialist personnel on site (e.g. ECoW, ACoW), Site Environmental Representative, etc.) to undertake specific toolbox talks or parts thereof as required.

2.2.8                     The Principal Contractor provides, as a minimum, training on the use of spill kits (on ground and in surface waters), to be provided on a regular basis (to account for staff/subcontractor changes etc).

2.2.9                     The Principal Contractor maintains a record of all tool box talks or other environmental related training sessions delivered, their content and the attendees.

Change Management

2.2.10                  During the construction of the Proposed Development, it is considered reasonable to presume that certain eventualities will partially or fully preclude the implementation of specific standards and processes outlined herein. In these events, the Principal Contractor provides justification to the Employer outlining the reasons for any departure and details a proposed alternative approach that does not compromise environmental protection.

2.2.11                    The alternative proposals shall only be adopted following consideration and acceptance of the Employer and the Site Environmental Representative where relevant.

2.3Reporting, Correspondence and Records

2.3.1                       The Principal Contractor provides a complete record of all relevant communication, and reports associated with all aspects of environmental management and implementation of the CEMP. As a guide, the following records will be maintained:

• Minutes and attendance record of start-up meeting (on site meeting prior to commencement of construction works). Attendance required by Environmental Manager, Site Environmental Representative  and all other relevant personnel responsible for environmental management during construction.
• Weekly rolling Environmental Risk Log including look ahead activities with required mitigation (including weather forecasts). This is required to be discussed and recorded at scheduled weekly construction meetings. This will cover all environmental sensitivities, including ecology and water quality. This will include a supporting Environmental Risk Map.
• Employer and Contractor Audit Reports
• Record of Toolbox Talks and Training
• Dust/noise monitoring records
• Waste Management Records
• Drainage Maintenance Register
• Water Quality Monitoring Records, documenting visual checks of waterbodies as outlined in the Pollution Prevention Plan (PPP)

• Regulatory Authority visits (e.g. SEPA, NatureScot), observations and communications
• General Correspondence - all other relevant internal and external communication records relating to environmental management issues and implementation of the CEMP.

Risk Assessments & Method Statements

Audits

2.3.2                      Audits may be completed at any time by the Employer, but at least one per quarter. All completed audit forms (and records of corrective action and close outs) must be filed and provided by the Employer to the Principal Contractor. The Principal Contractor will undertake a programme of environmental audits to satisfy conformity with CEMP principles, including audits of their sub-contractors and provide copies of the completed audit forms to the Employer.

Notice Boards

2.3.3                      The Principal Contractor provides and maintains project environmental notice board(s) which are positioned so that all operatives have the opportunity to review a notice board on a daily basis. As a minimum this will include one notice board to be placed at construction compound locations.

2.3.4                     The environmental notice boards are maintained by the Site Environmental Representative and shall be updated at least monthly. As a minimum, the notice boards contain:

• Description of the key environmental risks and intended risk mitigation measures.
• Accompanying Environmental Constraints Map illustrating the location of the key risks and required exclusion zones/buffer zones and location of emergency response equipment, as required by the CEMP; and
• Key contact numbers and responsible personnel identified within the Environmental Incident and Emergency Response Plan (EIERP).

2.4Pollution Prevention and Mitigation

2.4.1                       The Principal Contractor is responsible for pollution prevention for the duration of the works and until such time as permanent measures, such as permanent drainage and silt mitigation controls, are deemed to be adequate and appropriately constructed.

2.4.2                     The Principal Contractor will undertake a regular programme of dust and noise monitoring, including the inspection of relevant plant and vehicle parts.  This responsibility will include the actions of any third party who is sub-contracted by the Principal Contractor or otherwise involved in the Proposed Development.

2.4.3                     It is the responsibility of the Principal Contractor to contact SEPA, other statutory and non-statutory bodies in the vicinity of and downstream of the project so that the requirements and interests of these parties are adhered to and protected throughout the duration of the construction.

2.4.4                     The Principal Contractor will be familiar with and execute works in accordance with the guidance provided in the SEPA Pollution Prevention Guidelines and other guideline documents that will be detailed in this CEMP.

2.4.5                     All staff and subcontractors working on site will be issued with a copy of the CEMP to familiarise themselves with pollution prevention and mitigation measures as detailed in the CEMP and measures relevant to their role; this includes Principal Contractor’s employees, subcontractors, Employer’s direct contractors and other Employer’s representatives working on the site.

Controlled Activities Regulations Licensing

2.4.6                     A Construction Site Licence will be required under the Water Environment (Controlled Activities) (Scotland) Regulations 2011 (as amended) (the ‘CAR’ Regulations) and the Water Environment (Miscellaneous) (Scotland) Regulations 2017.

2.4.7                      A CAR Construction Site Licence is required for the site as a construction site that meets the following criteria:

• it comprises an area greater than 4 ha, or
• it is a linear development greater than 5 km, or
• it has an area of more than 1 ha or any length of more than 500 m on ground with a slope in excess of 25 degrees.

2.4.8                     A Construction Site Licence requires a PPP to be produced by the ‘Responsible Person’. Depending on the time available between contract award and construction start, the Employer may act as Responsible Person until such time as a Principal Contractor is appointed, at which point the licence and Responsible Person nomination will be transferred to the Principal Contractor. Upon transfer of the licence, the Principal Contractor will prepare any further site/works-specific plans and documents to update the PPP dependent on his design of the Works. These will be submitted with the licence transfer application prior to commencement of construction. A copy of the PPP will be included in Annex B.

General Pollution Prevention Measures

2.4.9                     The following points (not exhaustive) indicate general pollution prevention measures in accordance with those highlighted within the SEPA Pollution Prevention Guidelines referenced in this Outline CEMP and the Onshore EIA Report. Pollution Prevention measures relating to specific tasks are also detailed in the respective sections of this document.

• Any material or substance which could cause pollution, including fuels/oils, wet cement, raw concrete or silty water will be prevented from entering groundwater, surface water drains or watercourses by the appropriate use of and appropriate placement of (temporary) silt fences, cut-off drains, silt traps and drainage to vegetated areas where appropriate. Any sign of failing water treatment measures or sight of silted or contaminated water entering any watercourse on site will be reported immediately.
• Any silty water generated onsite will ideally be settled out as much as possible through drainage mitigation measures (e.g. horseshoe silt traps) and, where appropriate, released back into the watercourse.
• External fuel delivery lorries will only be allowed as far as the site compound where there will be a covered refuelling area equipped with an impermeable base. A double bunded fuel tank is preferrable.
• Fuel transfer/refuelling will be undertaken by specifically trained and competent staff or undertaken under competent supervision.
• Areas of waste oil/fuel/chemical storage and permanent refuelling will be located at least 30 m away from watercourses or drainage paths and contained within bunding which accommodates 110% of storage volume. Where this is not possible, advice will be sought from the ECoW, and a minimum distance will be agreed with the Employer. Such storage areas will be sited on an impervious base to prevent the downward percolation of contaminants to natural soils and groundwater.
• Fuel pipes on plant, outlets at fuel tanks etc will be regularly checked and recorded in accordance with Provision and Use of Work Equipment Pre-Use Checks or Plant and equipment, and maintained so that no drips or leaks to ground occur.
• All refuelling will occur on hardstanding or stoned tracks.
• Spill kits will be available within each plant on site and also located close to identified pollution sources or sensitive receptors (fuel storage areas, water course crossings, etc).
• Irrespective of the buffer distance and location of refuelling, interceptor drip trays (or similar, e.g. plant nappies, – open metal drip trays are not acceptable) will be available. Interceptor drip trays will be positioned under any stationary mobile plant to prevent oil contamination of the ground surface or water.
• All stockpiled materials will be stored in designated areas and isolated from any surface drains. Aggregate or fine materials storage with dust or run off potential will be enclosed and screened/sheeted.
• Washing-out of concrete wagons on site shall only be permitted when the Principal Contractor has provided a designated, suitably prepared wash-out area with signage identifying the area as suitable for concrete wagon wash-out.
• The concrete ‘washout’ in the designated area shall not be emptied into any watercourse and shall be appropriately treated or disposed of in accordance with the Site Waste Management Plan.
• Tools, equipment, or materials will not be washed in watercourses. Mortar mixing and material storage areas must be away from watercourses.

Dust Management Plan

2.4.10                  The Principal Contractor implements the following mitigation measures to minimise dust emissions during the Works:

• Wheel cleaning and lorry sheeting measures are employed to prevent mud, debris or other loose or deleterious material being deposited on the local road network.
• Similarly, any hardstanding areas for vehicle parking are kept clean and, if unsealed, are kept damp during prolonged spells of dry weather or as required to suppress dust emissions.
• Site entrances and the adjacent local road network are kept free of mud and other loose or deleterious material arising from construction traffic through use of a road sweeper where required.
• Dust generation on site haul roads and hardstanding areas is avoided or minimised by regular water spraying in dry weather spells or as required to suppress dust emissions.
• Excavations and excavated materials are kept damp by water spraying or misting and stockpiles are dampened down and if necessary, covered or screened. Waste material is stored in a controlled manner in a designated area.
• Adequate supplies of water are made available for use in dust suppression units/bowsers.
• Dust collection systems and/or dampening systems are used on all blast-hole drilling machines (if used). Borrow pit working areas are kept damp by water spraying or misting if required to suppress dust emissions.
• Site speed limit will be enforced.
• No burning of materials is permitted on site.

Construction Noise and Vibration Management Plan

2.4.11                    The Construction Noise and Vibration Management Plan will identify sensitive receptors taking cognisance of the the Onshore EIA Report findings and detail any mitigation measures in the Schedule of Mitigation and Planning Permission. A copy of the Construction Noise and Vibration Management Plan will be included in Annex C.

2.4.12                   Due to ecological sensitivity, any works within 1 km of designated sites (i.e. Special Protection Areas (SPA) and Special Areas of Conservation (SAC)) which may involve large scale noise or vibration (such as pile driving or blasting) will be undertaken, only with prior consultation with the ECoW.

2.4.13                   Working hours for construction activities will be agreed through the planning conditions with THC.

2.4.14                  In the event of work being required outwith these hours, e.g. abnormal load deliveries THC will be notified prior to these works taking place and will only proceed with their approval.

2.4.15                   To reduce the potential effects of construction noise, the Principal Contractor will apply the following types of mitigation:

• All construction activities shall adhere to good practice as set out in BS (British Standards) 5228.
• All equipment will be maintained in good working order and any associated noise attenuation such as engine casing and exhaust silencers shall remain always fitted.
• Where flexibility exists, activities will be separated from residential neighbours by the maximum possible distances.
• Construction plant capable of generating significant noise and vibration levels will be operated in a manner to restrict the duration of the higher magnitude levels.

COSHH

2.4.16                  The Principal Contractor is responsible for ensuring that all materials ordered or brought to site listed as hazardous under the Control of Substances Hazardous to Health (COSHH) Regulations 2002 as amended are accompanied with a hazardous information sheet. The Principal Contractor complies with the COSHH Regulations.

Monitoring & Controls

2.4.17                   The Principal Contractor will carry out regular inspections of oil/fuel storage areas and plant. The frequency and responsibility for undertaking these inspections will be recorded by the Principal Contractor and communicated to the Employer prior to commencement of the works.

2.4.18                  For compliance purposes  the Employer will regularly monitor the Principal Contractor’s works. Should the Employer identify failures to comply with the requirements of the CEMP or the Principal Contractor’s own method statements the Employer may stop the associated works until such time as the failure is rectified.

2.5Temporary Drainage

Minimum Requirements

2.5.1                       The Principal Contractor complies with conditions of the CAR Construction Site Licence and PPP, see Section 2.4.

2.5.2                      Temporary drainage should be as required to comply with SEPA guidance and must be designed to accommodate larger flows depending on the specific site conditions.

2.5.3                      The Principal Contractor designs and constructs a drainage system including all silt mitigation measures necessary to prevent the pollution of existing drainage systems and watercourses for construction and post construction activities.

2.5.4                     As a minimum all temporary drainage is installed as the track is constructed, where possible the permanent drainage is installed as the works progress. In the event that temporary drainage is installed at the time of construction the permanent drainage is installed within three months of that section of track being completed.

2.5.5                      All drainage associated with the works is not permitted to discharge directly into any existing drainage or watercourse without agreement with the ECoW.

2.5.6                     The Principal Contractor does not discharge water on either a temporary or permanent basis unless they have acceptance from the relevant stakeholders and the ECoW, and complied with the requirements of the relevant Authorities, Utilities and Service Providers.

Diversions

2.5.7                      Where possible, greenfield run-off will be kept separate from silty water or other potentially contaminated water. Where appropriate, interceptor ditches and other drainage diversion measures will be installed – in advance of any excavation works – in order to collect and divert greenfield run-off away from construction disturbed areas.

2.5.8                     The Principal Contractor channels silty and clean water drainage separately to designated areas (approved by ECoW) to allow the settlement of solids. Where settlement over vegetation is not practical or adequate to deal with the volume of silt generated, the Principal Contractor provides and maintains silt traps or settlement lagoons.

Silt Management and Settlement Ponds

2.5.9                     The Principal Contractor erects and maintains silt fences to protect all watercourses, which may be affected by the works. The Principal Contractor maintains these weekly to the satisfaction of the Project Manager and the ECoW.

2.5.10                  Silt laden run off should be expected from any areas of recently exposed soil or rock. This silt laden run-off will be captured and directed towards specially constructed sediment control structures.

2.5.11                    Where required, siting of settlement ponds will take into consideration access requirements for reinstatement and maintenance (for example: periodic silt removal, expansion of ponds or incorporation of additional silt mitigation measures, etc.)

2.5.12                   The Principal Contractor discusses and agrees the location of lagoons and other drainage mitigation measures with the ECoW prior to associated works taking place.

2.5.13                   Additional filtration measures may include flow attenuation measures such as weirs, rock bars and/or anchored and embedded straw bales within settling ponds or between series of ponds.

Foundations and Hardstanding

2.5.14                   Foundation excavations for the Proposed Development is below the level of the surrounding ground and hence surface water ingress from up slope or groundwater seepage may occur, leading to standing water within the base of the excavation. A ‘permit to pump’ procedure will be in place prior to water being pumped from an excavation. The Principal Contractor seeks the Site Environmental Representative’s and/or ECoW’s approval prior to granting a ‘permit to pump’.

Construction Compound and Control buildings

2.5.15                   As with all construction activities, greenfield run-off and development run-off will be kept separate and appropriate silt mitigation measures will be deployed. Pumping of water from excavations is subject to a ‘permit to pump’ (see Paragraph 1.7.14).

2.5.16                   The construction compound(s) is/are free draining and contain a bunded area draining to oil interceptor (or similarly robust alternative) for bulk fuel storage and maintaining vehicles and plant, or other pollution control measures, as appropriate/required to protect existing watercourses and private water supplies (PWS). Any alternative to a bunded area suggested by the Principal Contractor must be agreed with the Employer.

2.5.17                   The laydown area(s) are free draining for maintaining vehicles and plant, or other pollution control measures, as appropriate/required to protect existing watercourses and PWS.

2.6Water Quality Monitoring

Minimum Requirements

2.6.1                       In line with best practice, the Employer undertakes surface water quality monitoring where an impact on surface water bodies cannot be ruled out. The Employer considers it best practice to obtain baseline surface water quality data prior to commencement of the works, and to monitor water quality during the works in order to identify any significant changes of water quality which may be attributed to the construction works.

2.6.2                     The surface water monitoring programme is implemented and maintained by the Employer and either undertaken by the Employer’s environmental staff or by an environmental consultant appointed by the Employer.

2.6.3                     Where a decrease in water quality resulting from construction works is observed the Principal Contractor will undertake remedial measures.

2.6.4                     A Water Quality Monitoring Plan will be prepared following receipt of Planning Permission, and included in Annex D. The plan will detail proposed monitoring locations, monitoring frequency and analytical parameters based on the findings of the Onshore EIA Report and any subsequently submitted documents/information. The Water Quality Monitoring Plan will be submitted to THC post-consent/pre-commencement of works as part of the updated CEMP.

Monitoring Locations

2.6.5                     Monitoring of water quality will be carried out on selected watercourses; specific monitoring locations will be identified post-consent during the detailed design phase (pre-commencement of works).

Monitoring Parameters and Frequency

2.6.6                     Pre-construction monitoring is likely to be undertaken at least monthly for at least three months prior to construction to establish a baseline.

2.6.7                      Construction phase monitoring is likely to be undertaken at least monthly commencing within two weeks of start of works, and ad-hoc if deemed necessary, e.g. following a pollution incident.

2.6.8                     Post-construction monitoring is likely to be undertaken monthly for at least three months following completion of the main civil construction works.

2.6.9                     Monitoring of specific locations may cease within three months of works ceasing in a particular area, following consultation with SEPA where necessary.

2.6.10                  Where necessary surface water quality monitoring will include the monitoring of field parameters at each location prior to the collection of water samples at each location for analysis at a UKAS accredited laboratory.

2.6.11                    The field parameters monitored during each monitoring round and obtained via use of a hand-held monitoring device, are pH, electrical conductivity, temperature, and dissolved oxygen. Monitoring results will be recorded in the field.

Private Water Supplies

2.6.12                   PWS within 500 m of the construction area will be assessed to determine whether they are at risk from contamination due to construction activities. If required, the PWS will be diverted and/or safeguarded and baseline water quality monitoring of the properties downstream on the PWS will be undertaken. Monitoring would continue during construction and for a period following completion so that in the event of effects on the PWS they could be identified and further mitigation measures put in place.

2.7Waste Management

Site Waste Management Plan

2.7.1                       In accordance with best practice, the Employer requires a Site Waste Management Plan (SWMP) to appropriately document and control waste at construction sites. The SWMP will record all waste arising from the Proposed Development.

2.7.2                      The SWMP provides details on how waste reduction shall be implemented at the site and how this shall be monitored throughout the construction phase. The Principal Contractor’s nominated Site Environmental Representative takes responsibility for implementation and monitoring of the SWMP. A copy of the SWMP will be included in Annex E.

2.7.3                      The Principal Contractor will only utilise certified waste carriers/waste contractors and maintains records of these contractors (carriers, transfer station, waste recipient etc) as part of the SWMP documentation on site.

2.7.4                      The requirements of the SWMP are communicated to all site operatives during their induction. Furthermore, all operatives on site attend waste reduction toolbox talks on a regular (e.g. quarterly) basis to increase awareness of recycling/waste reduction.

2.7.5                      The SWMP includes the following as a minimum:

• Identification of the Employer, the Principal Contractor; the person(s) who drafted the SWMP and the person(s) who will be responsible for its implementation, monitoring, and review during and upon completion of construction works.
• The minimum percentage recycling level expected by the Employer of all materials removed from the site (measured in terms of tonnage).
• Various materials that will be required to facilitate construction and support the provision of welfare at the site. In the interests of promoting sustainability via the supply chain and minimisation of waste, the Principal Contractor investigates opportunity for procurement of materials with reduced or reusable/returnable packaging. Where such opportunities are realised, the Principal Contractor provides details in the SWMP.
• Waste inventory and procedures to address the following:
• a description of each waste type expected to be produced in the course of the Proposed Development, with the relevant European Waste Catalogue code assigned to it.
• an estimate of the quantity (tonnage) of each different waste streams/type of waste expected to be produced during each construction activity.
• a written statement demonstrating what actions are to be taken to minimise the volume of each type of waste produced prior to commencement of the activity generating the waste.
• Identification of the waste management actions proposed for each different waste type, including re-using, recycling, recovery, and disposal. For example, minimum provisions should include:
• provision of bins to segregate waste and recyclable materials within all welfare facilities in-line with the preliminary, non-exhaustive waste streams identified;
• provision of separate, suitably robust skips for general waste and separate recyclable materials within the main site compound in-line with the preliminary, non-exhaustive waste streams identified;
• management of expected and unexpected hazardous/special waste. i.e. provision of secure bunded containers to store waste oils/fuels/lubricants and oily rags prior to removal from site.
• re-use of materials such as concrete formwork and reinforcement “seating” steel.
• material arising from excavation works may be reused as fill material where suitable (and not posing environmental risks);
• A site plan showing all water disposal/recycling locations and material storage areas
• Identification of the proposed Waste Contractor(s) and the requirements imposed on them, i.e. completion of Waste Transfer Notes (WTN).
• WTN for all materials removed from site comprising the following information:
• European Waste Catalogue (EWC) codes.
• description of waste removed from site.
• date and time waste removed from site.
• weight (in tonnes) of waste removed from site.
• name of Waste Contractor Operative.
• location of waste disposal site which is to be used; and
• weigh of waste/recyclable material, i.e. waste facility will include weight bridge
• All estimated and actual waste itemised (by waste stream as a minimum) in cubic meters or tonnes and the recovery rate.

Records (implementation, monitoring & auditing)

2.7.6                      For monitoring and auditing purposes, the Site Environmental Representative implements and maintains a Waste and Recycling Record under the SWMP. As a minimum, this includes a record of all waste leaving the site for either landfill disposal or recycling, including copies of all WTN in-line with the requirements of Section 2.7.5. The Waste and Recycling Record will be maintained and kept up to date by the Site Environmental Representative.

2.7.7                      The Site Environmental Representative checks the contents of the site waste and recycling skips on a weekly basis to confirm waste is being correctly segregated. Non-compliance will be highlighted at the weekly progress meeting and appropriate actions taken e.g. a toolbox talk to all site operatives. Furthermore, the Employer and Contractor audit the waste disposal chain to demonstrate compliance with the responsibilities outlined in Duty of Care for Waste and refers to the good practice principals detailed in A Simple Guide to Site Waste Management Plan, especially the Principal Contractor audits against the checklist in Part Three of the guide.

2.7.8                      Waste management will be a recurring agenda item for all regular meetings as required by the CEMP. The Site Environmental Representative provides an update on the achieved percentage of recycling and any actions that are required to be implemented.

2.7.9                      Waste management is monitored by the Site Environmental Representative and reviewed monthly against the estimate set within the detailed SWMP. Where necessary, changes are implemented in order to revise site activities if performance is below the set recycling target.

2.7.10                   Upon completion of works, the SWMP will be provided to the Employer. This will contain pre-construction estimated and actual waste itemised (by waste stream as a minimum) in cubic meters or tonnes and the recovery rate of each waste, including waste quantities for recovery/diversion from landfill.

Construction Waste Streams

2.7.11                    A number of different waste streams are likely to arise during construction. The Principal Contractor identifies all waste streams and provides an estimate of expected waste volumes for each waste type generated within the waste stream.

2.7.12                   The Principal Contractor will prepare a SWMP taking into account relevant information provided by the Employer and other stakeholders (for example intrusive ground investigation data, supply chain assessments, options appraisals etc).

2.7.13                   The section below sets out a non-comprehensive list of waste streams that typically arise during construction of the Proposed Development:

• waste from welfare facilities, e.g. food waste, paper, plastics, glass, and other typically domestic refuse and sewage.
• concrete wash water
• waste chemicals, fuel and oils.
• packaging, e.g. paper, plastics and wood.
• waste metals; and
• cleaning activities, e.g. polluted water from plant and vehicle washdown.
