PP - for development consisting of a ten-year planning permission for a renewable energy development with a 30-year operational life (from the date of commissioning along with a recreational and amenity facility. The entirety of the renewable energy development constitutes the provision of a ten-turbine wind farm and associated site works on lands in both Counties Leitrim and Sligo. The development will consist of: i. Construction of 2 no. wind turbines with a maximum overall blade tip height of up to 170 metres and associated hardstand areas; ii. 1 no. permanent Meteorological Mast with a maximum height of up to 100 metres, iii. All associated underground electrical and communications cabling connecting the turbines to the proposed wind farm 38kV electricity substation (which is proposed to be located in the townland of Garvagh Glebe, Co Leitrim); iv. Upgrade of existing tracks, roads and provision of new site access roads; v. Recreation and amenity works, including marked trails and associated recreation and amenity signage; vi. Site drainage; vii. Permanent signage; viii. Ancillary forestry felling to facilitate construction and operation of the proposed development; and ix. All associated site development works. A concurrent planning application is being lodged with Leitrim County Council in relation to the elements of the project that are within County Leitrim (which include the provision of 8 no. wind turbines, electrical substation, underground cabling, connection to national electricity grid, access tracks/roads, access junction improvements, amenity works and all associated works). An Environmental Impact Assessment Report (EIAR) and a Natura Impact Statement (NIS) have been prepared in respect of the proposed development and will be submitted with the application.

Development consisting of an existing lattice type temporary meteorological mast 80m in height and associated instrumentation and works and the continuation of its use to measure local climate conditions for a period of a further five years

For the installation of approximately 0.46km of underground cable ducting, 1 no. joint bay and ancillary development laid primarily within the public road corridor, with a section of circa. 0.07km within private lands at Seltan. A Section of ducting is to be installed within a steel box structure to be fixed to Boleymaguire Bridge within the townland of Boleymaguire, Co. Leitrim. Within the townland of Boleymaguire, permission is sought for the carrying out of remedial works to approximately 0.44km of the installed underground cable ducting which is subject to a pending application for Substitute Consent to An Bord Pleanála (Ref: ABP-300811-18), remedial works include the relaying of backfill material. Permission is also sought for the installation of the electricity cable following the completion of the civil works. The development will comprise part of an overall development in Counties Leitrim, Sligo and Roscommon, consisting of the laying of an underground 38 kv electricity cable and associated ducting and ancillary development primarily within the public road to facilitate the connection of the permitted Derrysallagh Wind Farm, Co Sligo (Sligo County Council planning reference: PL 12/133) to the national electricity grid via the existing Garvagh 110kv substation in the townland of Seltan, Co Leitrim. Part of this development is in place and subject to a pending application for Substitute Consent to An Bord Pleanala (ref: ABP-300811-18). This application is accompanied by an Environmental Impact Assessment Report (EIAR)/Environmental Impact Statement (EIS).
