The findings of this Environmental Report support an outline planning application to East Devon District Council (EDDC) for the construction and operation of a converter station on land to the east of Exeter Airport in association with the FAB Link Interconnector. Introduction to the FAB Link Interconnector 1.2 FAB Link is a proposed interconnector which will allow the exchange and trading of up to 1400MW of electricity between France, Alderney and Britain. The cable will cross the channel island of Alderney in order to connect future renewable tidal stream generation in the seas around Alderney. 1.3 The main components of the FAB Link Interconnector are shown on Figure 1.1 and comprise: • High Voltage Direct Current (HVDC) electricity cables buried in or placed (and protected) upon the sea bed between the Contentin (or Cherbourg) Peninsula, Normandy, France and the South Devon coast of Britain – the Offshore Cable Route; • HVDC electricity cable landing and traverse (as underground cables) of the Channel Island of Alderney; • HVDC onshore and offshore cable ‘transitions’ at the shorelines of all three territories; • HVDC to High Voltage Alternating Current (HVAC) converter stations in both Normandy and Devon; and • HVDC onshore cables from the transition points to the converter stations and HVAC onshore cables from the converter stations to substations in both territories –– the Onshore Cable Route. • Connection to the electricity system in Great Britain via the high voltage National Electricity Transmission System (NETS) substation near Exeter, operated by National Grid Electricity Transmission (‘National Grid’). 1.4 The FAB Link Interconnector is designated as a Project of Common Interest (PCI) under the Connecting Europe Facility and has received financial support for its development under that programme. It has been granted an Interconnector Licence by the Gas and Electricity Markets Authority and has been granted Interim Project Approval under the interconnector “cap and floor” regime by The Office of Gas and Electricity Markets (Ofgem). 1.5 FAB Link Ltd is developing the applications for the UK onshore, UK offshore and Alderney elements of the FAB Link Interconnector (as shown on Figure 1.1). December 2016 1-1 FAB Link Interconnector: UK Converter Station Environmental Report Chapter 1: Introduction Selection of the HVDC Converter Station Site 1.6 The selection of the connection point to the UK National Grid is described in the UK Connection Point Selection Report (Transmission Investment, 2016). 1.7 Factors such as land availability, proximity to the NGET substation, access, planning and environmental constraints led to the selection of the preferred converter station site near to Exeter Airport in 2015, which overall was determined to be most consistent with the project’s efficiency and cost requirements. The detail of the selection process is provided in the HVDC Converter Station Site Selection Process Report (RPS, 2015).

  • CDWM Bulletin
    Capital Development & Waste Management Bulletin w/c 24th November 2014 EDG DEVON COUNTY COUNCIL CYCLEWAY SCHEME WINS NATIONAL GREEN APPLE AWARD The Exe Estuary Trail’s River Clyst Bridge scheme has beaten some very prestigious and large projects across the UK to become National Green Champion during the International Green Apple Awards for Environmental Best Practice and Sustainable Development 2014. The bridge scheme was the brainchild of our Engineering Design Group who commissioned contractor Dyer and Butler to design and build the final structure that linked Exmouth to Topsham. Dyer & Butler submitted the project for the Green Apple Award and along with Clive Ryall, Senior Engineer in our Bridges Group attended the Award Ceremony in early November that was held on the Terrace Pavilion of the House of Commons. The team thought the scheme would be in with a chance of a commendation but winning the National Title was beyond their expectations with so much competition. The Project in context - The Exe Estuary is a Special Protection Area (SPA), Site of Special Scientific Interest (SSSI) and has Important Bird Area (IBA) and Ramsar designations. Due to the exceptionally environmentally sensitive nature of the area, site activities were strictly controlled with construction only being allowed between March and September. As a result the scheme was built over a two year period with completion in November 2013 From Bowling Green Road in Topsham, the Trail runs through the RSPB Goosemoor Nature Reserve on 225 metres of boardwalk and elevated ramp, then passes over a new 114 metre span bridge to join the previously constructed sections of the Exe Estuary Trail to Exton and beyond.

  • Parishes of Clyst St Mary and Sowton Administered As Bishops Clyst
    HIW/16/9 Public Rights of Way Committee 24 November 2016 Definitive Map Review 2015 - 2016 Parishes of Clyst St Mary and Sowton administered as Bishops Clyst Report of the Chief Officer for Highways, Infrastructure Development and Waste Please note that the following recommendation is subject to consideration and determination by the Committee before taking effect. Recommendation: It is recommended an Order be made to add a Public Footpath in Sowton Parish between points A-B-C-D-E-B and F-G as shown on plan HCW/PROW/16/12v2. 1. Summary The report examines the Definitive Map Review for the Parishes of Clyst St Mary and Sowton, which are administered as Bishops Clyst, in East Devon District. 2. Background/Introduction The original survey, under s. 27 of the National Parks and Access to the Countryside Act 1949, revealed three footpaths and no bridleways in Clyst St Mary, and six footpaths and no bridleways in Sowton, which were recorded on the Definitive Map and Statement, St Thomas Rural District with the relevant date of 1 June 1957. The review of the Definitive Map, under s. 33 of the 1949 Act, which commenced in the 1970s, but was never completed, produced no proposals for change to the map in the parishes. The Limited Special Review of Roads Used as Public Paths (RUPPS), also carried out in the 1970s, did not affect these parishes. The following orders have been made and confirmed: County of Devon Stopping up Order Clyst St Mary Part of FP1 Town and Country Planning Act 1964.

  • The Evolution of the Rivers of East Devon and South Somerset, UK
    R.W. Gallois THE EVOLUTION OF THE RIVERS OF EAST DEVON AND SOUTH SOMERSET , UK R.W.G ALLOIS Gallois, R.W. 2006. The evolution of the rivers of east Devon and south Somerset, UK. Geoscience in south-west England, 11 , 205-213. With the exception of the River Tone, which appears to have been separated at an early stage from its neighbours to the south by a major fault, the rivers of south Somerset and east Devon were initiated on a southward dipping Tertiary planation surface. The evolutionary histories of the present-day catchments of the rivers Exe and Otter are complex and inter-related. Those of the adjacent Axe and Teign appear to be less complex and may have evolved relatively independently from the Exe-Otter system. The differences in the histories of the catchments are most clearly demonstrated by their terrace systems. The Exe-Otter catchment has 10 or more terrace levels at heights of up to 140 m above the modern floodplain. In contrast, the Axe, Teign and Tone catchments contain only one or two terrace levels all of which are less than 20 m above the present-day valley floor. The explanation suggested here for the difference involves a sequence of river captures that changed the forerunner of the present-day Otter from a major river capable of producing a 3-km wide gravelly braidplain into a minor stream. 92 Stoke Valley Road, Exeter, EX4 5ER, U.K. (E-mail: [email protected]). INTRODUCTION The middle and lower reaches of the River Exe and the There are too few age data to determine the period of time adjacent catchments of the Axe, Otter, Teign and Tone drain an during which the terrace sequences in south-west England area with a complex topographical relief that ranges from over evolved, but comparison with the denudation chronology of 300 m above Ordnance Datum (O.D.) in the Blackdown Hills southern England as a whole suggests that all the terraces to a few metres above O.D.
