The development will also include an access road onto an existing Roscommon County Council owned road with access via the Monksland Industrial Estate; 13 no. car parking spaces; footpath; landscaping, 3m paladin security fence; and all other associated site development works including surface water and foul drainage required to facilitate the development. (The proposed power plant is a project type that requires an Industrial Emissions Licence from the Environmental Protection Agency in accordance with the requirements of the First Schedule to the Environmental Protection Agency Act 1992) at

Permission for amendments to the permitted gas-fired power plant at this site in Monksland, Athlone, Co. Roscommon (Reg. Ref. PD/18/256, as amended by PD/22/234, PD/24/60393 and PD/25/60336). The development will consist of a revised internal layout of the permitted workshop building, resulting in a partial change of use of a permitted storeroom, to a control room with an office and communications room, and the change of use of the permitted office to a kitchenette. The total size of the workshop building will remain unchanged. The gas-fired power plant development permitted under Reg. Ref. PD/18/256 includes activities which are subject to an Industrial Emissions Licence under ref. P1197-01 at

Permission and Retention Permission for amendments to a permitted gas fired power plant development under Reg. Ref. PD/18/256 (amended by Reg Ref. PD/22/234 and PD/24/60393). Permission is sought for amendments to the surface water drainage design to incorporate improved SuDs measures, including the provision of 2 no. attenuation ponds. Retention permission is sought for the: • Amalgamation of the permitted workshop, storeroom and admin building. • Rearrangement and minor alteration of the permitted security hut, gas pressure reducing skid (GPRS), and Tank Farm building. • Inclusion of GPRS control building. • Inclusion of an additional lube oil tank in the tank farm. • A 4.1m increase in height of the permitted external radiators. • A reduction in height of the permitted electrical annex building by 2.85m. • The addition of 5 no. Air Outlet Ventilation units on the roof of the permitted Engine Hall. The gas fired power plant development permitted under Reg. Ref. PD/18/256 includes activities which will be subject to an Industrial Emissions Licence. An updated Appropriate Assessment Screening Report (AASR)/ Natura Impact Statement (NIS) and updated Flood Risk Assessment Report (FRA) are submitted as part of this planning application at

Permission for development consisting of amendments to development granted under Register Reference PD/18/256 for a gas fired power plant in Monksland, Athlone, Co. Roscommon and subsequently amended by Reg. Ref. PD/22/234. Permission is sought for revisions to the layout of the Above Ground Infrastructure (AGI), associated with Gas Network’s Ireland’s high-pressure gas supply to the power plant. The revisions include a new revised AGI site entrance with access gate, amendments to the internal road network, amendments to the security fencing, a new pedestrian entrance/exit, a revised and new emergency exit, repositioning of the existing pig trap, repositioning of site security fencing, the addition of a temporary pig trap base, removable bollards, an electrical metering cabinet, an ESB electrical pole, an Electrical & Instrumentation kiosk, a regulators/metering kiosk, packaged boiler unit kiosk and a gas analyser kiosk. No changes are proposed to the permitted onsite drainage. The development permitted under Reg. Ref. PD/18/256 includes activities which will be subject to an Industrial Emissions Licence. An updated Natura Impact Statement (NIS) has been prepared for this development and is submitted as part of the planning application at

Permission for development consisting of revisions and alterations of the permitted development of a gas fired power plant under Planning Register Reference PD/18/256. The revisions and alterations relate to the design of the gas fired power plant and will include a change to the electrical output of the power plant to 102MW with associated balance of plant, equipment and buildings including: an engine hall building with a height of 16.9m, (comprising 5 no. gas engines and ancillary infrastructure), an electrical annex building with a height of 18.7m; A workshop building with a height of 5.1m; An administrative building with a height of 6.1m; A tank farm building with a height of 5.7m; A security hut with a height of 3.3m; An exhaust stack with a height of 28.0m; A gas AGI including an instrument kiosk with a height of 4.9m and an analyser kiosk with a height of 2.9m; 2 no. storage containers, each 2.6m in height, radiator coolers with height of 8.5m; Tanks including 2 X diesel oil storage tanks (volume of 1860m3 combined); SCR urea tank (73m3); Lube oil storage tank (3m3); Lube oil maintenance tank (26m3); Pilot oil tank (26m3); Fire water storage tank (563m3); Waste oil effluent tank (16m3); Underground surface water attenuation tank (590m3). The revised proposal will involve a revised red line site boundary to provide for drainage and other works within the adjacent roadway. The development optimises the same access permitted under PD/18/256 and includes 12 no. number parking spaces, footpaths, landscaping; fencing and all other associated site development plant and equipment and other works including surface water and foul wastewater drainage, all on site 1.8 hectares in size (A Natura Impact Statement(NIS) is submitted as part of the planning application) ( Permission is sought for a period of 10 years) at

Permission for development for upgrade works to the existing wastewater treatment plant including the construction of preliminary treatment works, storm tank and overflow pipelines, demolition of existing preliminary treatment works and existing disused sludge drying beds and all associated site development and site excavation works above and below ground at
