The Neart na Gaoithe (NnG) Offshore Wind Farm (Revised Design) received consent under Section 36 of the Electricity Act 1989 from the Scottish Ministers on 3 December 2018 and was granted two Marine Licences by the Scottish Ministers, for the Wind Farm and the associated Offshore Transmission Works (OfTW), on 3 December 2018. The S36 consent and Wind Farm Marine Licence were revised by issue of a variation to the S36 Consent and Marine Licence 06677/19/0 on 4 June 2019, and the OfTW Marine Licence by the issue of Marine Licence 06678/19/1 on the 5 June 2019 and subsequently by MS-00008954 on the 12 October 2020. The Project is being developed by Neart na Gaoithe Offshore Wind Limited (NnGOWL). 2. The Wind Farm Area is located to the northeast of the Firth of Forth, 15.5 kilometres (km) directly east of Fife Ness on the east coast of Scotland (see Figure 1). The Wind Farm Area covers approximately 105 km2. Offshore Export Cables will be located within the 300 metre (m) wide Offshore Export Cable Corridor, running in an approximately southwest direction from the Wind Farm Area, making landfall at Thorntonloch beach to the south of Torness Power Station in East Lothian. Construction began in Quarter 3 of 2020 and is planned to be completed by Quarter 4 of 2022. 3. NnG Offshore Wind Farm comprises of the following main components: • 54 wind turbines with a maximum generating output of around 450 Megawatts (MW). • 54 jacket substructures installed on pre-piled foundations to support the wind turbines. • Two alternating current (AC) substation platforms, referred to as Offshore Substation Platforms (OSPs), to collect and transform the generated electricity from 66 kilovolts (kV) to 220 kV for transmission to shore. • Two jacket substructures installed on piled foundations, to support the OSPs. • A network of inter-array subsea cables, buried and/or mechanically protected, to connect strings of turbines together and to connect the turbines to the OSPs. • One interconnector cable connecting the OSPs to each other. • Two buried and/or mechanically protected subsea export cables to transmit the electricity from the OSPs to the onshore buried export cables at landfall at Thorntonloch. This will facilitate connection to the National Grid network. • Minor ancillary works such as the deployment of metocean buoys and permanent navigational marks. 1.2 Purpose of the Environmental Report 4. NnGOWL is seeking to apply for a Marine Licence from Marine Scotland Licensing Operations Team (MS-LOT) for the installation of a pontoon at their Operations & Maintenance (O&M) Base at Eyemouth Harbour. A Marine Licence is required for any marine construction works under the Marine (Scotland) Act 2010. 5. This Environmental Report is submitted in support of the Marine Licence application to provide an overview of the baseline environment and any potential impacts from the pontoon installation and operation. Consent for the onshore aspects of the O&M base at Eyemouth Harbour was granted on 14 September 2020 from the Scottish Borders Council under The Town and Country Planning (Scotland) Act 1997. 6. NnGOWL has secured exclusive use of the Gunsgreen Basin with existing pontoons for leisure craft and fishing vessels to be removed by Eyemouth Harbour Trust (EHT) prior to site handover. 7. A description of the pontoon is provided in Section 2, a description of the baseline environment is provided in Section 3 and an assessment of potential impacts is presented in Section 4.

    By Tilly Reynolds and Caitlin Griffith VICTORIAN NATIONAL PARKS ASSOCIATION The Victorian National Parks Association (VNPA) helps shape the agenda for creating and managing national parks, conservation reserves and other important natural areas across land and sea in Victoria. The VNPA works with all levels of government, the scientific community and the general community to achieve long term, best practice environmental outcomes. The VNPA is also Victoria’s largest bushwalking club and provides a range of information, education and activity programs to encourage Victorians to get active for nature. REEF WATCH Reef Watch is a citizen science program run by the VNPA. The program encourages divers and snorkellers to monitor marine life at their favourite dive sites. The project has been developed by the Australian Marine Conservation Society and the Marine and Coastal Community Network. Reef Watch co-ordinates a number of marine conservation programs, including ‘Feral or in Peril’ and the Great Victorian Fish Count. In 2012 Reef Watch won the 2012 award for Excellence In Education from Victoria’s Coastal Council.

[Victoria Government Gazette No. G39 12 October 1988 p.3092] Transferred to the Victorian Heritage Register 23 May 1998 (2 years after the proclamation of the Heritage Act 1995 pursuant to the transitional provisions of the Act) Statement of Significance: South Channel Fort, constructed between 1879 and 1888, was designed by Colonel Peter Scratchley of the Royal Engineers using the 'Twydall Redoubt' principles of sand parapets to be the key fort in the network of the outer defences of Port Phillip protecting it from anticipated naval attacks in the late nineteenth century. The fort was intended to play a key role in holding enemy ships in a triangle of fire between Queenscliff, Point Nepean (or Point Franklin) and its own guns; and to lay, control and test the minefield in the South Channel. 1 The fort is an artificial island built up on 14,000 tonnes of bluestone boulders and concrete with sand overburden. It is 121.9 metres long, 76.2 metres wide and 6.4 metres high above sea level. The fortifications comprise a concrete and red-gum military dugout bunker system which is mainly underground with some areas breaking the surface as gun emplacements facing south and as a service yard facing north.

  • Popular Rhymes of Scotland : Original Poems
    POPULAR EHYMES OF SCOTLAND. RHYMES ON PLACES. Natural objects of a conspicuous kind, as mountains and rivers, attract the attention of the rudest people, and pro- bably are the lirst which receive names in the infancy of a newly-settled country. There is a disposition in Scotland, and probably in other countries, to work up the names of such objects in verse, sometimes with associated circum- stances, but often with little besides a bare enumeration or list. Thus arises a large class of what may be called Topo- graphical Rhymes. In some instances the ideas introduced are of a striking- and poetical nature ; and it is worthy of remark, that, even where the names alone are given in the versified list, there is usually a euphony in the structure of the verse, which makes it tell on the simple ear like a strain of one of our pastoral melodies. In other instances, these rhymes are curious on account of the grotesque words which they introduce to notice. It would almost appear as if the composers of such verses had addressed themselves on some occasions to select a set of the most whimsical names of places and men in their vicinity, for the amuse- ment of strangers. Another section of our topographical rhymes contain allusions to events of a public or private nature, or pre- dictions of events expected yet to come. Others relate to things for which the places were remarkable. ' ! — —— — POPULAR RHYMES OF SCOTLAND. BERWICKSHIRE.
