Environmental Statement Volume 4 Appendix 23.1: Mitigation Schedule

1. Introduction 1) The following appendix summarises the mitigation proposals which are presented in Volume 2 of the ES. The mitigation proposals have been collated from each of the technical chapters. While the appendix captures the mitigation proposals as they presently stand, it is acknowledged that some may continue to evolve and be further enhanced during the planning determination process and in the development of planning conditions, should the planning authorities be minded to approve the application. 2) The mitigation schedule links into an Environmental Masterplan for the Proposed Scheme (Appendix 23.2). The Masterplan comprises a series of drawings illustrating the locations at which both generic and site- specific mitigation measures are proposed. 3) The mitigation schedule is presented according to EIA topic areas, and follows the same order of topics as presented in the ES.

Environmental Statement Volume 4 Appendix 23.1: Mitigation Schedule

3. Arboriculture

Receptor/ Scheme Component/ Construction Stage/ activity Mitigation

Scheme Wide – Construction • It is important that measures for protection are in place throughout the scheme and for as long as a risk of damage remains. Particular care and planning is necessary in the operation of excavators, lifting machinery and cranes so all vehicle movements and lifting operations will not impact on retained trees • The retained trees should be adequately protected by stout fencing, ‘fit for purpose’ and preferably as prescribed in section 6.2 of British Standard 5837: 2012 to provide an adequate RPA that will allow its successful retention within the development • The RPA should be regarded as sacrosanct and the fencing should be installed prior to construction works, and plant and machinery arriving on site. The fencing should remain intact throughout the duration of the scheme and only be removed upon completion. The position of the fencing around the trees should be shown on the tree protection plan (TPP) once the scheme layout has been finalised • During construction there should be no materials stored or dumped and no vehicular or plant movement within the RPA to minimise the risk to the trees from soil compaction. Where compaction has occurred advice should be sought from an arboriculturist and a structural engineer on decompaction methods. This is in accordance with Section 8.4 of BS5837:2012 • All site storage areas, cement mixing and washing points for equipment and vehicles and fuel storage areas should be outside RPAs unless otherwise agreed with the LPA. No discharge of potential contaminants should occur within the RPA of a retained tree stem or where there is a risk of run off into RPA • Excavations within the root protection area should be avoided. However, if excavations are necessary, works should be limited to the use of hand tools. Great care should be taken to preserve and work around roots greater than 25 mm in diameter and clusters of smaller roots avoiding damage to bark. Where it is necessary to sever roots greater than 25 mm in diameter, advice from an arboriculturist should be sought. Where smaller roots must be severed they should be cut back using secateurs or a sharp pruning saw • Where construction working space or temporary construction access is justified within the RPA, this should be facilitated by a setback in the alignment of the tree protection barrier. Where the set-back of the tree protection barrier would expose unmade ground to construction damage, new temporary ground protection should be installed as part of the implementation of physical tree protection measures prior to work starting on site.

Environmental Statement Volume 4 Appendix 23.1: Mitigation Schedule

Receptor/ Scheme Component/ Construction Stage/ activity Mitigation

• New temporary ground protection should be capable of supporting any traffic entering or using the site without being distorted or causing compaction of underlying soil. The ground protection might comprise one of the following: a) For pedestrian movements only, a single thickness of scaffold boards placed either on top of a driven scaffold frame, so as to form a suspended walkway, or on top of a compression-resistant layer (e.g. 100 mm depth of woodchip), laid onto a geotextile membrane b) For pedestrian-operated plant up to a gross weight of 2 tonnes, proprietary, inter-linked ground protection boards placed on top of a compression-resistant layer (e.g. 150 mm depth of woodchip), laid onto a geotextile membrane c) For wheeled or tracked construction traffic exceeding 2 tonnes gross weight, an alternative system (e.g. proprietary systems or pre­ cast reinforced concrete slabs) to an engineering specification designed in conjunction with arboricultural advice, to accommodate the likely loading to which it will be subjected. • Wherever possible, underground utility services should be routed outside the RPA. Where underground apparatus is to pass within the RPA, detailed plans showing the proposed routing should be drawn up in conjunction with a competent arboriculturist.

Scheme Wide • Compliance with the Code of Practice for Pipelaying: Consultation with landowners and occupiers should be undertaken when developing the programme of works to reduce disturbance where appropriate and without detriment to the overall programme. Specifically, the pre-construction consultation with agricultural and sporting land interests should result in agreement of farm specific procedures and dates of entry and expected exit dates. It should also identify the need for and extent of derogations to environmental agreements and Basic Payment Scheme.

Scheme Wide • Compliance with the Code of Practice for Pipelaying: Notice of Entry and Notice to Carry out Works provided to the owners and occupiers of affected land interests in writing prior to the commencement of works. This should provide information on the construction works and should include a plan to illustrate land interests to amend Basic Payment Scheme claims and support submission of environmental agreement derogations.

Scheme Wide • Compliance with the Code of Practice for Pipelaying, Soil Management Strategy, Drainage Strategy and Biosecurity Management Plan: Pre-construction surveys of land and drainage to provide a schedule of condition and inform soil management strategy, drainage strategy and biosecurity management procedures. Additionally, the survey should identify the location of existing field watering points and access arrangements and should identify the need for alternative provision.

Scheme Wide • Compliance with the Code of Practice for Pipelaying: Temporary fences in appropriate locations during construction should be provided for the health and safety of the public, protection of animals, and to avoid trespass. Where appropriate, fencing of the working area, site compounds and laydown areas is to be to a standard adequate to exclude any stock kept on adjoining land. Stockproof fencing should be maintained during the course of the works and any new fencing should be strained next to the existing fencing through provision of straining posts.

Scheme Wide • Compliance with the Code of Practice for Pipelaying: Water troughs and field supplies located within the working area should be moved to a new temporary or agreed permanent location. Where required, alternative watering points for livestock in severed areas should be provided through provision of temporary alternative supplies linked to existing water supply systems or, failing that, provided by bowser.

Scheme Wide • Compliance with the Code of Practice for Pipelaying: Access to agricultural and sporting land managed by the land interest should be maintained at all times during the construction process. Existing means of access should be maintained where practicable. Where a common access is to be shared use, the access should be kept as clear as possible from materials arising from the construction works and there should be a minimum interference for emergency vehicles. Public access rights should be maintained.

Scheme Wide • Compliance with the Code of Practice for Pipelaying: Where access points require temporary or permanent alteration as a result of construction, alternative access for stock and machinery should be provided as appropriate in consultation with the land owner/ occupier. If appropriate, temporary foot crossings, gates, steps and stiles should be provided.

Scheme Wide • Compliance with the Code of Practice for Pipe Laying: Measures to prevent the straying of livestock onto the working width or other designated construction areas should be implemented during the construction period.

Scheme Wide • Compliance with the Materials Management Plan, Code of Practice for Pipe Laying: Where removal of boundary features is required to allow construction, existing materials such as stone from walls should be protected where practicable and stored to facilitate their re-use in reinstatement. The effect of works on field boundary hedges should be subject to the Hedgerow Regulations 1997 as amended.

Scheme Wide • Compliance with Drainage Strategy, Code of Practice for Pipe Laying: Particular care should be taken to reduce damage or disturbance to known land drainage systems. Where required, the integrity of the existing land drainage system should be secured in advance through the installation of new drains to facilitate construction.

Scheme Wide • Compliance with Soil Management Strategy, Drainage Strategy and Code of Practice for Pipe Laying: Potential for damage to the integrity and agricultural capability of topsoils and subsoils should be minimised by the adoption of appropriate measures and in accordance with good practice during topsoil and subsoil stripping and storage. Topsoil should be stored separately from other materials and should not be compacted by machinery. Topsoil stores should be managed to prevent erosion and ingress of weeds.

Scheme Wide • Compliance with Drainage Strategy and Code of Practice for Pipe Laying: Where land drainage systems are disturbed, these should be reinstated or replaced to the same standard as existed prior to the works and as recorded in the schedule of condition survey to ensure that agricultural land capability is maintained and flooding is not exacerbated. Where unknown land drainage systems are discovered, the land interest should be informed. The land interest should be informed of the timing of remedial works and be given the opportunity to inspect the site. A record of the land drains disturbed and the replacement/reconnection work carried out should be made and a copy made available to the land interest. In the event that land drainage system is deemed by the land interest to be not adequately reinstated to the state recorded in the schedule of condition, an independent drainage specialist may be engaged to provide advice.

Scheme Wide • Compliance with Soil Management Strategy and Code of Practice for Pipe Laying: Potential for damage to the integrity and agricultural capability of topsoil and subsoil should be minimised by the adoption of appropriate measures and in accordance with good practice during excavation of topsoil storage mounds, loose tipping of topsoil, levelling, stone picking, removal of debris and their subsequent reinstatement to grass or crop. Subsoil preparations should be undertaken prior to replacing topsoil to reduce compaction. Excavated topsoil should be replaced to the same location as it was stripped and to the same topsoil depth. If, for any reason, the same topsoil that was removed cannot be replaced, it should, unless otherwise agreed, be replaced with soil of a similar nature, structure and quality. The land should be restored to the same condition that it was in before works commenced and as recorded in the schedule of condition survey. Before land in the working area is handed back, a joint inspection should be completed to determine its condition against the schedule of condition. In the event that the land in the working area is deemed by the land interest to be not adequately reinstated to the state recorded in the schedule of condition at the point of handing back, an independent agricultural specialist may be engaged to provide advice.

Scheme Wide • Compliance with Code of Practice for Pipe Laying: Where boundary features have been damaged or removed, these should be repaired or replaced as necessary and, in the case of walls, using original material where practicable. Where hedges have been damaged or removed, these should be replanted with appropriate species and a secure protective fence should be erected to allow the hedge to become established. Repaired or replaced fencing should be stockproof fencing.

Scheme Wide • Compliance with Code of Practice for Pipe Laying: Sporting or fishing rights which exist within the working area should not be accessible during the construction period. Where there are sporting or fishing rights adjacent to the working area, reasonable endeavours should be taken to minimise interference or enjoyment of them while recognising the primary objective to maintain a safe working environment for both contractors and users of the land.

13. Traffic and Transport

Receptor/ Scheme Component/ Construction Stage/ activity Mitigation

Scheme Wide – Construction Stage Traffic Management Plan – keys Heads of Terms to be agreed with Cumbria County Council and Highways England for inclusion within a Construction Management Plan for contractors to follow including: • Routeing Strategy HGV Movements associated with the Import and Export of Materials shall observe the proposed routeing strategy, following the principal roads operated by Cumbria CC and Highways England. This includes the following: Pipes would be imported by sea to either Barrow-in-Furness, Heysham or Workington ports, depending on the favoured location of the appointed contractors. The pipes would be delivered to the temporary compound locations closest to the working area. It is expected that Cumbria CC, Highways England and the Police would be involved in discussions with the contractors and that the favoured routeing for pipe movements from the identified ports would be via the A590 / M6 / A66 to the southern/western section and A590 / M6 / A595 to the northern sections. Where the existing road network is not suitable for articulated lorries, the delivery would take place at the nearest laydown area on route to the working area, where the pipes would be stored and should then be distributed along the pipeline spread via suitable means, such as tractor and trailer. All other materials would be delivered to the site as follows: • A66 through M6 Junction 40 at Penrith, then A591: this route would be used for deliveries to Raw Water Aqueduct from Bridge End connection to associated laydown areas • A66 through M6 Junction 40 at Penrith, then A595: this route would be used for deliveries to new mains from Cockermouth to Bridekirk, including Water Treatment Works. • A66 through M6 Junction 40 at Penrith: this route would be used for deliveries to both slip-lines, connecting through B5292 / B5289 to Cornhow. • A66 through M6 Junction 40 at Penrith, then A5086: this route would be used for deliveries to new mains from Cockermouth to Summergrove, including Harrot Hill Pumping Station and High Ley Service Reservoir. • A595 through Junction 44, at Carlisle, then A689, and A595: this route would be utilised for deliveries to new mains from the Proposed WTW to Quarry Hill, Moota Hill Service Reservoir, the north of Raw Water Aqueduct and associated compound/laydown areas.

Any surplus excavated materials to be removed to Moota Quarry (CEMEX) and Lillyhall Landfill using the A66 and A595 as follows: • To Moota Quarry (CA13 0QE), the surplus excavated material from: - New mains from Proposed WTW to Quarry Hill - The first 6 km of new mains from Proposed WTW to Summergrove - Cockermouth to Cornhow - 30% of Raw Water Aqueduct (the last 9.6 km) - Moota Hill Service Reservoir • To Lillyhall Landfill (CA14 4JH): the surplus excavated material from: - The last 19.4 km from Proposed WTW to Summergrove. - Stainburn to Papcastle - 70% of Raw Water Aqueduct (the first 22 km) - High Leys Service Reservoir and Pumping Station - Harrot Hill Pumping Station It would be the responsibility of the contractor to ensure that its own vehicles and those of third party sub-contractors adhere to the routeing strategy. The following measures are proposed with respect to ensuring compliance: • Driver information / training and provision of copies of the appropriate local HGV routeing plans to drivers • Driver disciplinary procedures, including banning from site / dismissal should repeated flouting of the local routeing strategy be identified • Community liaison and encouragement of local residents to report of incorrectly driven vehicles.

Environmental Statement Volume 4 Appendix 23.1: Mitigation Schedule

Receptor/ Scheme Component/ Construction Stage/ activity Mitigation

It is noted that there are a number of locations where the receptors are classed as sensitive, namely areas where there is frontage property including retail and a school, where the presence of HGV activity may not be suitable at specific peak periods of the day due to on-street parking and inherent width constraints in the highway. Specific areas where this should be noted are at Bothel, Rowrah, Frizington, and Cleator Moor. In this instance, a dialogue should be opened with Cumbria to ensure that HGV movements do not coincide with periods where the presence of HGVs would be most apparent and potentially problematic, namely school opening and closing times. Agreement of an appropriate strategy at these specific locations should serve to minimise any impacts that may arise in association with HGVs using local roads.

Construction Travel Plan It is fully recognised that the potential to reduce private car usage through the promotion of sustainable alternatives is limited within the rural context of the proposed construction period and subsequently operable pipeline infrastructure. As such the following measures are proposed as a means to limit the impacts that employee travel may have on the local highway network and the immediate environs of the laydown areas: • Encouraging staff involvement in a car sharing scheme. Employees should be encouraged to car share with other staff members via a staff matching scheme operated on recruitment. Alternatively staff should be encouraged to investigate other car sharing options (where practical, dependent on staff shift times) including national car share websites such as www.liftshare.com or www.nationalcarshare.co.uk • Management of the car parking resource within compound areas to ensure that local parking does not become problematic within surrounding residential areas. Where demand exceeds supply, steps would be taken to ensure staff travel in multi-occupancy vehicles from a remote location, based on proximity of residence.

14. Noise and Vibration

Scheme Component Receptor/ Scheme Component / construction stage/ activity Mitigation

Scheme-wide General Mitigation: • Avoid revving of engines and ensure that plant and equipment is switched off when it is not in use for longer periods of time • Ensure construction activities are undertaken during the least sensitive periods i.e. avoiding night-time and weekend working • Should blasting be required then blasts shall be designed to minimise adverse impacts and meet the requirements outlined within BS 6472-2, namely: “Blasts should be designed to result in a vibration level of no greater than 3 mm/s at the nearest residential properties (6 mm/s is the limit for residential properties, but BS 6472-2 suggests that blasts need to be designed to ensure that the average level of vibration is approximately half of the specified limit). In terms of air overpressure blasts should be designed to result in levels that do not exceed 120 dB (lin) at the nearest properties” • Keep haul roads well maintained and avoid steep gradients • Start-up plant and machinery sequentially rather than all together • Select low noise and vibration emitting plant where available and suitable, particularly when working in noise and vibration sensitive areas • Use audible reversing warning systems on mobile plant and vehicles should be of a type that, whilst ensuring that they give proper warning have a minimum noise impact on nearby sensitive receptors • Vibration soil compaction plant shall be set to a low amplitude setting when operating in close proximity to sensitive receptors

Scheme-wide • Develop and maintain good relations with people living and working in the vicinity of site operations and ensure that residents are given advanced notice of any construction activities that should be particularly noisy • Establish agreement with the LPA on appropriate controls for undertaking particularly noisy works or vibration causing operations close to receptors • Implement an efficient communications strategy with local residents and businesses including a compliance procedure • Avoid hammer driven piles where practicable and where sheet piles are required consider the use of acoustically dampened sheet steel piles to reduce levels of resonant vibrant. • Where viable, the use of temporary noise screens around particularly noisy activities (or stationary plant such as generators) • Regular plant maintenance • Where practicable consider the use of low noise equipment.

Construction Noise

RWA Scheme Section 2-5 (Bridge End Connection and RWA) • An assessment should be carried out in any areas where rock is encountered and proposed rock breaking methods are to be used. A full risk assessment should be undertaken on a case-by-case basis and appropriate control measures implemented • Where high strength rock is encountered, blasting techniques should be undertaken in accordance with the guidance contained within BS 6472-2. Advance warning should be provided to residents in affected areas.

Scheme Section 3 – Keswick (Tunnelling and Piling) • Consideration of alternative methods of piling such as secant (auger bored) piling • Low vibration techniques for tunnelling within Keswick

Proposed WTW Scheme Section 6 – Proposed WTW • Erection of temporary noise barriers around particularly noisy plant or equipment or around the site perimeter • Creation of permanent bunds at the start of works where practicable.

Proposed WTW to Scheme Section 11-15 (Harrot Hill PS to Summergrove) • Erection of temporary noise barriers around noisy equipment and plant or around the perimeter of the compounds Summergrove Laydown locations near: Spring Wells in Dean scales; Keekle • Reuse of excavation material to create temporary bunds at the edge of the compound / laydown area to mitigate Terrace in Cleator Moor and Wood Moor in Lamplugh noise.
