4 1 General The Construction Traffic Management Plan is in connection with the development and installation of a single wind turbine and ancillary works on land at Bridgemoor, Millbrook. 2 Public Engagement The Parish Council and local highways department will be notified prior to commencement on site and provided with a copy of the Construction Traffic Management Plan. During construction the contact details for an on-site representative will be made available. 3 Construction Programme Site deliveries, utilising larger vehicles, of equipment to site will be phased over an eight week construction period, thereafter the majority of vehicles requiring access to the site will be small commercial vehicles and cars. Construction is anticipated to commence following receipt of planning consent and discharge of any pre-commencement conditions An overview of the project construction programme is set out in section 12 of this report. 4 Working Times Construction of the development will be undertaken 7 days a week. All deliveries will be between 7.30am and 5.30pm. Deliveries to the site will be staged within this time period with drivers given specific time windows for arrival at site. The anticipated number and frequency of vehicle movements are set out within section 8.1 below. 5 Construction Traffic Route to site The planned route for all major deliveries of materials is shown in Figure 1 below, the photographs are set out in sections at the end of the report. The identified construction traffic delivery route is proposed to leave the A38 at Trerulefoot, turning left onto the A374 following the road to Antony. Construction vehicles such as abnormal loads will be required to turn around at the A374/Trevol Road junction, approximately 1km east of the A374/Antony Hill junction). Once reaching Antony turning left onto A374/Antony Hill signposted to Millbrook. At the T junction vehicles will turn left continuing on the B3247 signposted Whitsand Bay. Turn right onto Withnoe Lane and proceed to the site entrance. The proposal will require a permanent new access track from the existing gateway to facilitate access to the turbine during the construction and operational phase (shown in photo 6 in section 15). A new temporary access will be constructed to allow the delivery vehicles of the main turbine component parts to safely enter and exit the site in forward gear. A condition survey will be undertaken and agreed with the local Highway Authority (Area Network Manager) prior to commencement of work on site and used as a reference following the construction period. The applicant undertakes to rectify any damage caused to the road or verges as a direct result of traffic associated with the construction of the development.

A permanent new access track will be constructed from the site entrance to facilitate access to the base of the proposed turbine during the operational period from the existing field gate, as illustrated in drawing ref: 1164e/D004. Whilst there is an existing access from the public highway, a new temporary access will be constructed for the construction period to safely accommodate construction traffic and in particular delivery of the main turbine component parts. This will be reinstated after the construction period has completed. A methodology has been provided in Appendix 1, which outlines the removal and reinstatement for the temporary access track. 7 Site Compound There will be a hard standing area as shown on the development layout drawings submitted with the application. This is for the temporary storage of equipment and materials during construction and parking for site vehicles as shown on the proposed site layout plan. The hard standing area has Aardvark EM Limited September 2015 Page 2

8 8 Deliveries Site deliveries of equipment to the site, utilising larger vehicles, will be phased over an eight week construction period, thereafter the majority of vehicles requiring access to the site will be small commercial vehicles and cars. All deliveries will be between 7.30am and 5.30pm. Deliveries to the site will be staged within this time period with drivers given specific time windows for arrival at site. The anticipated number and frequency of vehicle movements are set out below. Due to the relative lack of neighbouring properties to the application site, it is not considered necessary to formally notify local residents of the construction phase period. However, as set out below appropriate traffic warning signs will be put in place (subject to prior notification of the Highways Authority). Access for emergency vehicles will be maintained at all times. 8.1 Anticipated Vehicle Movements Construction traffic will comprise delivery of the turbine and attendant infrastructure, concrete for the turbine base and sub-structure and materials for the access road. Delivery of the turbine and ancillary equipment to the site will comprise heavy and abnormal goods traffic and will comprise up to 10 vehicles over one or two days:- 1. The blades are fitted within transport frames, grouped into a set of three blades and are delivered in one telescopic semi-trailer truck load; 2. The blade hub, transformer and other auxiliaries are delivered in two truckloads; 3. The tower is delivered in two sections and two standard truck and trailer loads; 4. The nacelle is delivered in one truck load; 5. The large ring generator is delivered in one truck load; 6. One ton main crane and one 90 ton hydraulic tail crane. The materials for the new access road and hardstanding concrete for the turbine base/crane pad will generate approximately 10 HGV vehicle movements per day. Other vehicle movements associated with the development will comprise cars and small commercial vehicles for site workers. 8.2 Traffic summary Deliveries will be timed to prevent multiple HGV s arriving at once. This will prevent any potential for HGV s to park on the public highway. However the construction compound will also be able to accommodate more than one HGV if necessary as stated above. 9 Lighting for Construction and Security External lighting will be used during the construction period if required and only between the hours of and Aardvark EM Limited September 2015 Page 5

9 10 Storage of Oils, Fuels and Pollution Prevention 10.1 Oil and Fuel All oil and fuel will be stored in 1m³ fuel containers in accordance with specific UK Regulations e.g. The Control of Pollution (Oil Storage) (England) Regulations 2001 (OSR England) Other Hazardous Material No other hazardous material will be stored on site Dust and Dirt A temporary wheelwash will be located on site during the construction periods, for all vehicles exiting on to the public highway in wet periods to avoid depositing mud onto the road. Similarly, in excessively dry periods the section of the highway immediately either side of the access will be swept if there is excessive dust 11 Ecological and Habitat Protection The potential for impacts during the construction and operation phases are considered below Construction Period During the construction phases there are predictable adverse effects which are generally unavoidable; many are temporary or short term and can be minimised as part of the construction management, but some have the potential for more lasting effect. The potential for adverse effects arises largely from disturbance including noise, vibration, light, dust, and human presence. These would be minimised as far as possible through the application of good practice techniques and adherence to well-designed method statements. Whilst only minor earthworks are proposed such as levelling and cable trenching, there is potential to increase soil erosion from the site during periods of heavy rainfall. Drainage control measures will be applied to ensure that during construction contaminated water is not released off-site. However, it is likely that following construction normal flow rates would soon return as any additional sedimentation is transported downstream. This effect would be unlikely, temporary and minor adverse. There is potential that accidental spills during construction of fuel and/or chemicals could introduce pollutants into the receptor, particularly during periods of heavy rainfall. Should this occur the effect would be likely, temporary and minor adverse Operational Period It is anticipated that the majority of vehicle movements to the site will be during the construction phase period for the delivery of materials and technical equipment (turbine, inverter station, mounting structure, cables and materials for the construction of the access track and hard standing areas). Once construction is complete, the site will require only periodic visits, for occasional repair and maintenance work. The existing access is considered sufficient for this purpose.

10 As set out in the submitted Design & Access statement the field will remain in agricultural use post development therefore the access will be retained and maintained for that purpose. 12 Construction Programme The proposed construction timeline is set out below and the construction of the site is anticipated to be approximately weeks. This may vary dependent on weather and other constraints unknown at this stage. Construction of the development will be undertaken 7 days a week. No activities audible from the boundary of the nearest noise sensitive receptor shall take place on Sundays during the construction period or at times outside 07:00 and 19:00. The proposed hours of working during the construction period will be between 7.30am and 5.30pm with the intention to avoid use of local highway network for deliveries during peak hours ( & ). Stage 1 Formation of temporary access track, cable trenches, casting substation foundations, security fence and CCTV cameras/poles Weeks 1-2 Stage 2 Installation of ground piles Weeks 2-4 Stage 3 Stage 4 Stage 5 Erection of mounting framework, fixing panels and routing of cables Installation of inverters, HV substations and all cabling and Commissioning Reinstatement of temporary tracks, hard standing and open storage areas Weeks 2-9 Weeks 9-10 Weeks Stage 6 Operation Weeks Programme of Works Once the Programme of Works has been confirmed with the preferred installer including the delivery schedule, it will be submitted in writing for approval by the LPA and Devon and Cornwall Police Abnormal Loads team for approval prior to commencement of development.

15 METHOD STATEMENT FOR THE TEMPORARY REMOVAL OF THE HEDGE AT BRIDGEMOOR RATIONALE The hedgerow adjacent to Withnoe Lane is to be taken down to allow access to the site for the turbine machinery. The hedgerow will be re-instated after all construction work has been completed. DESCRIPTION OF THE HEDGEROWS Generally the hedgebanks on site are over-managed and therefore structurally poor in terms of woody vegetation; they are all Cornish hedges (i.e. stone and earth banks to about 1m high). There is a single hedge that has to be partially removed. This is the hedge along Withnoe Lane. This is a heavily managed close-cropped flat-topped hedgebank. The road side is dominated by grasses such as Yorkshire Fog with Common Nettle, Lesser Celandine and Ivy also present. The field side is more overgrown and is dominated by Bramble with Hart stongue Fern and Blackthorn also present. In total, the hedge consists of 60% grassy and herbaceous species. The structural features are the height, width of the hedge and the materials used in its construction. The key ecological features are: Potential presence of reptiles especially Common Lizard and Slow Worm. Potential presence of small mammals including rats. The potential presence of nesting birds during the nesting season (March to August inclusive). RELEVANT LEGISLATION Wildlife and Countryside Act 1981 (as amended) The four widespread reptile species are listed under Schedule 5 of the Wildlife and Countryside Act 1981 (as amended) in respect of Section 9(5) and part of Section 9(1) whereby individual animals are protected from intentional killing or injury and also from sale or attempted sale. Section 1 of the Wildlife and Countryside Act 1981 prohibits the intentional killing, injuring or taking of any wild bird and the taking, damaging or destroying of the nest (whilst being built or in use) or eggs. Nests may be lawfully destroyed when not in use, i.e. outside the nesting season (September to February).

16 Wild Mammals (Protection) Act 1996 A wild mammal is defined as one which is neither domestic nor captive. This act makes it an offence to mutilate, kick, beat, nail or otherwise impale, stab, burn, stone, crush, drown, drag or asphyxiate any wild mammal with intent to inflict unnecessary suffering. METHOD FOR REMOVAL AND RE-INSTATEMENT The aim is to retain the materials for re-instatement and avoid adverse effects on protected species and habitats. The hedgerow should be taken down under a watching brief by a suitably qualified ecologist. The removal method of the hedge should be stone by stone by a small excavator with a toothed bucket, each time watching for small animals. Any small animals found should be caught by the ecologist, removed from the immediate work site and placed in a place of safety in one of the adjacent hedges. All material (stone earth and turf) should be retained for re-use. Stone material should be piled up together for re-use. Soils should be stored on an impermeable geo-textile membrane for re-use and sheeted-over to prevent wash-ff. Turf should be kept to one side and re-used, to be relaid on the upper face. The hedge should be rebuilt by hand so that it is contiguous with the adjacent hedgeline. The hedge should be replanted with locally sourced Blackthorn once it has been rebuilt.
