Monaghan (referred to hereafter as the Proposed Development and the Site . The proposed development works are to facilitate infill and re- contouring of the subject lands using soil, subsoil, and inert material to reclaim the land for agricultural purposes. Further information was requested from Monaghan County Council Item 3 (d) Demonstrate the suitability of the proposed development site for the importation of the proposed waste material. Details shall include an assessment on the impact this development and the proposed waste type will have on groundwater, surface water, and air, including identification of potential pathways to groundwater and surface water and any nearby drinking water supply sources and wells and identify proposed mitigation measures to protect groundwater and surface water from activities associated with this development. This information shall be completed by a qualified environmental consultant. 1.1 Project Objectives The objective of this Environmental Assessment was to establish the baseline environmental conditions at the Site and to identify the potential for any impacts associated with the Proposed Development. In particular, the assessment sought to: • Establish the baseline environmental conditions at the Site, including the geological, hydrogeological, hydrological, and local environmental setting. • Assess whether the Proposed Development has the potential to impact the receiving environment, including groundwater, surface water, air quality, and sensitive receptors located downgradient of and adjoining the Site. • Identify potential pathways through which the proposed activities could impact groundwater, surface water, and air quality. • Determine whether the Proposed Development could affect the Water Framework Directive (WFD) status of water bodies associated with the Site. • Identify appropriate mitigation measures to prevent or minimise any potential environmental impacts arising from the Proposed Development. 1.2 Project Scope The scope of the assessment included the following tasks: • A desk-based review of published information and information pertaining to the Site and Proposed Development. • Site walkover survey of the Proposed Development Site • Develop a hydrogeological conceptual site model (CSM) for the Proposed Development. • Identify and assess any potential impacts associated with the Proposed Development on sensitive receptors associated with the receiving environment. 1.3 Statement of Qualifications Traynor Environmental Ltd are a specialist environmental practice which delivers a range of water and environmental management consultancy services to the private and public sectors across Ireland.

RECEIVED: 29/03/2026 Environmental Assessment 5 2.0 Description of the Proposed Development 2.1 Site Location The proposed site is located at ING E 278981 N 315531 The site is situated at lands in Binmore, Castleblayney, Co. Monaghan. 2.2 Proposed Development The proposed development will consist of: • the re-contouring of existing undulating agricultural farmland to include the importation of soil, subsoil and inert material in order to raise the levels of part of the land together with all ancillary site development works. The lands will be recovered with topsoil and reseeded with ryegrass upon completion of the re-contouring works. 2.3 Relevant Guidance Documents The following guidance documents relevant to construction activities and the protection of groundwater, surface water and air quality were consulted in the preparation of this Environmental Assessment: • Environmental Protection Agency (2022): Advice Notes on Current Practice in the Preparation of Environmental Impact Assessment Reports (EIAR). • Environmental Protection Agency (2011): BAT Guidance Note on Best Available Techniques for the Waste Sector: Landfill Activities. • Institute of Geologists Ireland (2013): Guidelines for the Preparation of Soils, Geology and Hydrogeology Chapters of Environmental Impact Statements. • National Roads Authority (2005): Guidelines on Procedures for Assessment and Treatment of Geology, Hydrology and Hydrogeology for National Road Schemes. • CIRIA (2001): Control of Water Pollution from Construction Sites – Guidance for Consultants and Contractors (CIRIA C532). • Environmental Protection Agency (2021): Air Quality in Ireland – Key Indicators of Ambient Air Quality. • Institute of Air Quality Management (IAQM) (2014): Guidance on the Assessment of Dust from Demolition and Construction. • UK Department for Environment, Food and Rural Affairs (DEFRA) (2010): Guidance on the Assessment of Dust from Construction and Earthworks. 2.4 Geology & Hydrogeological/Hydrological Impact Assessment Methodology The conventional Source–Pathway–Receptor (S-P-R) model (see graphic below) for groundwater and surface water protection has been applied to assess potential impacts on groundwater, surface water, and groundwater supplies. In the case of the Proposed Development, the primary activity is the infilling and re-contouring of agricultural lands using inert greenfield soil and stone. The principal potential hazards associated with this activity are suspended solids during construction, accidental spillages of fuels or oils from plant, and sediment-laden runoff during heavy rainfall events. It is emphasised that the proposed infill material will consist solely of inert, uncontaminated greenfield soil and stone. As such, no hazardous, biodegradable, or chemically reactive materials will be accepted at the Site, and no significant leachate generation is anticipated. There are no watercourses within the application boundary. Local agricultural drains are located approximately 60 metres north of the Site and flow northwards toward the Rossollus Stream, which lies approximately 585– 604 metres northeast of the Site. There is no direct hydrological pathway between the Site and these drainage features. The underlying bedrock aquifer (Oghill Formation) is classified as a Poor Aquifer (PI) within the Cavan Groundwater Body (IE_NW_G_061). The primary receptors considered in this assessment include: • The underlying bedrock aquifer and associated groundwater resource; • Local domestic wells within the wider area; and RECEIVED: 29/03/2026 Environmental Assessment 6 • Surface water bodies within the Rossollus Stream catchment. Where potential impacts on groundwater or surface water quality or quantity are identified, the classification of impacts follows the definitions provided in the Glossary of Impacts contained within the following EPA guidance documents: • Advice Notes on Current Practice in the Preparation of Environmental Impact Statements (EPA, 2017); and • Guidelines on the Information to be Contained in Environmental Impact Assessment Reports (EPA, 2022).

The survey confirms that the subject lands comprise predominantly agricultural grassland with variations in ground levels across the site. The floor level of the proposed infill area ranges from approximately 170.97m – 183. 98m.The southern portion of the site is generally lower-lying relative to surrounding lands and will require the majority of the proposed infill material in order to achieve the intended re-contouring and restoration levels. The site lies within a rural agricultural setting and is accessed via an existing entrance off a local road serving the surrounding agricultural lands. The surrounding area is characterised by agricultural farming activities, predominantly livestock grazing and improved grassland. The proposed development seeks to re-contour the existing undulating farmland through the importation of suitable greenfield soil and stone, restoring the lands to a more uniform and agriculturally beneficial profile for ongoing use by the landowner. The site is situated within the gently undulating drumlin landscape typical of County Monaghan. Land use in the surrounding area is predominantly agricultural grassland, interspersed with hedgerows and mature treelines forming field boundaries. Several drainage features and minor surface water channels are present within the wider landscape context. The Rossollus Stream lies approx. 585m to the northeast of the site at a distance sufficient to ensure that, with appropriate buffer zones and mitigation measures in place, no direct hydrological connectivity will arise from the proposed infill activities. The rural character of the site, its agricultural context, and the absence of industrial or urban land uses in proximity support its suitability for the proposed soil and stone restoration works. Figure 2.1 - Site Location Map RECEIVED: 29/03/2026 Environmental Assessment 8 Figure 2.2 – Site Location Map. Application Site is Outlined in Red Other lands surrounding the Application Site can be characterised as rural in nature, with most land uses in the area being agricultural and single-house residential. The lands to the north, south and eastern boundaries of the Site are in agricultural use. Several farmsteads and one-off houses are located within 500 m radius of the Site. Figure 2.3 – Site Layout Plan RECEIVED: 29/03/2026 Environmental Assessment 9 3.2 Rainfall and Evaporation The application site is located within a temperate maritime climatic zone typical of County Monaghan. Based on long-term Met Éireann data from the Ballyhaise Meteorological Station, the average annual rainfall in the region is approximately 1,040 mm per annum. Rainfall is distributed throughout the year, with higher levels typically recorded during winter months. The prevailing climatic conditions are typical of rural agricultural lands in the region and do not present any unusual hydrological constraints in the context of the proposed inert soil and stone restoration works. 3.3 Hydrology and Catchment The application site is located within the Erne Hydrometric Area (36) and Catchment (36), the Dromore_SC_010 Sub- Catchment and the Major Lough Stream_010 Sub-Basin. Drumlane Lake lies approx. 797m northwest from the site boundary. The Rossollus Stream lies approx. 585m to the northeast of the site at a distance sufficient to ensure that, with appropriate buffer zones and mitigation measures in place, no direct hydrological connectivity will arise from the proposed infill activities. There are drains approximately 60m north of the site. These drains flow in a northerly direction toward the Rossollus Stream, which forms part of the wider local surface water network. There is no direct surface water pathway from the application site to the identified drains, and no runoff from the site discharges to these drainage features. The Environmental Protection Agency (EPA) has classified the ecological status of the Rossollus Stream within the wider catchment as being of Poor Ecological Status. Under the requirements of the EU Water Framework Directive (2000/60/EC), Moderate status is below the target objective, and the waterbody is required to achieve at least Good Ecological Status within the prescribed planning cycle. The proposed development has been assessed in the context of these objectives. Given the absence of any direct hydrological connection between the application site and the Rossollus Stream, and with the implementation of appropriate mitigation measures, the proposed infilling activities will not adversely affect the ecological status or water quality objectives of the Rossollus Stream or the wider catchment area. Figure 3.1: Regional Hydrology Map – Site Marked with an X (EPA Maps.ie) RECEIVED: 29/03/2026 Environmental Assessment 10 3.4 WFD Groundwater Body Status The Cavan Groundwater Body (GWB) (EU Code: IE_NW_G_061) in which the site is located is assigned ‘Good Status’ (www.wfdireland.ie), this applies to both quantitative status and chemical stat us. The objectives for the GWB is to protect the current ‘Good Status’ condition. This requires that the chemical and quantitative status of the Cavan GWB needs to be maintained. With regards to the proposed development, this means that the proposed infilling should not affect the chemical or quantitative status of the groundwater b ody. Figure 3.2: Layout showing Groundwater Body 3.5 Soil and Subsoil The soils beneath the Site are mapped by Teagasc (Teagasc, 2022) indicates that the site is derived from mainly non - calcareous parent materials (Bedrock at surface-Non calcareous). Subsoils beneath the Site are mapped by the GSI (GSI, 2022) shows that Hydrogeological setting as not mapped. There are no gravel aquifers mapped within a 2.0km radius of the Proposed Development site (GSI, 2022). The GSI have assigned a groundwater vulnerability rating of “Rock at or near Surface or Karst” (X) for the groundwater beneath the Proposed Development Site (GSI, 2022) indicating approximately 0m to 3m of overburden. The mapped subsoils in the vicinity of the site are Bedrock outcrop or subcrop. The GSI mapped quaternary soils are shown in Figure 3.3. RECEIVED: 29/03/2026 Environmental Assessment 11 Figure 3.3: Quaternary Sediments 3.6 Bedrock Geology The Geological Survey Ireland (GSI, 2026) classifies the bedrock underlying the Proposed Development Site and surrounding area (Oghill Formation) as a Poor Aquifer (PI), defined as bedrock that is generally unproductive except for small, locally productive zones. Poor aquifers are typically capable of supplying only small domestic-scale yields and are not considered regionally significant groundwater resources. In this type of bedrock setting, groundwater flow is generally limited and occurs primarily through secondary permeability features such as fractures, fissures, and joints rather than through primary intergranular porosity. As a result, groundwater movement is typically restricted and discontinuous. The GSI bedrock geology mapping for the site and surrounding area is presented in Figure 3.4. RECEIVED: 29/03/2026 Environmental Assessment 12 Figure 3.4: Bedrock Geology 3.7 Aquifer Classification and Vulnerability Rating The bedrock is classified as a Poor Aquifer (PI) (i.e., bedrock which is generally unproductive except for Local Zones) (GSI, 2026). The GSI has assigned a groundwater vulnerability rating of “Rock at or near Surface” (X) for the groundwater beneath the Proposed Development Site. The GSI Groundwater Aquifer Classification map is provided in Figure 3.5, and the Groundwater Vulnerability map is presented in Figure 3.6. Figure 3.5: Bedrock Aquifer RECEIVED: 29/03/2026 Environmental Assessment 13 Figure 3.6: Groundwater Vulnerability Map 3.8 Groundwater Use and Source Protection. Based on the GSI mapping there are no groundwater protection zones for existing public water or group water schemes mapped in the site. There are no domestic wells located within 50m of the boundary of the site. According to the GSI well database there is only 3 no. registered well within 1km of the site. There are no source protection zones within the Site boundary, with the nearest source protection areas located approximately 14.29 km to the southeast of the Site, at Killanny- Reaghstown. Figure 3.7: Location of Surrounding Wells & Springs RECEIVED: 29/03/2026 Environmental Assessment 14 Figure 3.8: Groundwater Flow Direction 3.9 Recharge There are limited surface water features in the proposed development site. Most of the rainfall landing on the site either recharges to groundwater, flows to the low points of the site or is lost to evaporation. As previously stated, there is a small pond / wetland in the site where surface water collects due to the topography. The bedrock aquifer beneath the Site is located within the Cavan Groundwater Body (GWB) (EU Code: IE_NW_G_061), as defined under the Water Framework Directive. This groundwater body is an extensive management unit encompassing groundwater resources across a large part of north-west Ireland, including parts of Counties Cavan and Monaghan. The Cavan GWB has been delineated by the EPA and Geological Survey Ireland based on hydrogeological and catchment criteria. 3.10 Regional and Local Hydrogeology The site is underlain by the Silurian Metasediments and Volcanics (SMV) aquifer, specifically the Oghill Formation. The Geological Survey Ireland (GSI) classifies this bedrock as a Poor Aquifer (PI), defined as bedrock that is generally unproductive except for small, locally productive zones. In this type of aquifer, groundwater movement occurs predominantly through secondary permeability features such as fractures, fissures, and joints rather than through primary intergranular porosity. Groundwater flow is therefore limited and typically confined to shallow weathered and fractured zones. Recharge in the vicinity of the Proposed Development occurs predominantly via diffuse percolation of rainfall through the overlying subsoils and thin till deposits into the fractured bedrock. The National Recharge Map (GSI, 2013) classifies the si te as having a recharge rate in the range of 51–100 mm per year, which is consistent with the low permeability characteristics of Poor Aquifers in the region. Due to the limited productivity of the underlying bedrock and the relatively low recharge rates, groundwater–surface water interactions are expected to be localised and limited. A proportion of effective rainfall is likely to discharge as surface runoff RECEIVED: 29/03/2026 Environmental Assessment 15 to local drainage features, particularly given the drumlin topography and variable subsoil thickness across the site. There are no gravel aquifers mapped within a 2.0km radius of the Proposed Development site (GSI, 2026), reducing the regional hydrogeological sensitivity. 3.11 Designated and Protected Sites (Natura 2000) A review of the National Parks and Wildlife Service (NPWS) mapping confirms that there are no Special Areas of Conservation (SACs), Special Protection Areas (SPAs), or other European designated sites located within 15km of the Proposed Development Site. The Habitats Directive (92/43/EEC) seeks to conserve natural habitats and wild fauna and flora through the designation of Special Areas of Conservation (SACs), while the Birds Directive (2009/147/EC) provides for the protection of bird species through the designation of Special Protection Areas (SPAs). SACs and SPAs are collectively referred to as Natura 2000 sites (or European Sites). Based on a review of available mapping and hydrological information, there are no Natura 2000 sites within the zone of influence of the Proposed Development Site, and no potential hydraulic connectivity has been identified between the site and any European designated site. Accordingly, the proposed development is not expected to have any direct or indirect impact on European Sites. Figure 3.9: Designated and Protected Areas RECEIVED: 29/03/2026 Environmental Assessment 16 3.12 Water Framework Directive Status The Water Framework Directive (WFD) status of surface water and groundwater bodies relevant to the Proposed Development Site has been reviewed using the EPA WFD Map Viewer (EPA, 2026), in accordance with the European Communities (Water Policy) Regulations 2003 (S.I. No. 722 of 2003, as amended). There are no watercourses within the application boundary. Local field drains are located approximately 60m north of the site and flow northwards toward the Rossollus Stream. There is no direct surface water pathway from the site to these drains. The Rossollus Stream is the nearest mapped WFD surface waterbody within the wider catchment. The Site is located outside of any designated transitional or coastal waterbody zone of influence. The groundwater beneath the site forms part of the Cavan Groundwater Body (IE_NW_G_061), as defined by the EPA under the WFD. A summary of the relevant WFD waterbodies is provided in Table 3.2.

The assessment is based on the Conceptual Site Model (CSM), also referred to as the Source–Pathway–Receptor (S-P-R) framework, which underpins the objectives of the Water Framework Directive (2000/60/EC) and associated EPA and GSI groundwater protection guidance. The purpose of the assessment is to determine whether the proposed infilling activities could give rise to pollutant linkages capable of impacting identified receptors, including surface water bodies within the wider catchment, groundwater within the underlying aquifer, and potential human health receptors such as private groundwater supplies. For a risk to exist, all three elements of the pollutant linkage must be present: a contaminant source, a viable migration pathway, and a sensitive receptor. If any one of these elements is absent, the linkage is incomplete and the risk is considered negligible. In accordance with the ‘prevent or limit’ principle of the Water Framework Directive, the primary mitigation measure is the restriction of accepted material to inert greenfield soil and stone only. By controlling the source at origin, the potential for contaminant release is effectively eliminated. 4.2 Hydrogeological Conceptual Site Model The Site is underlain by the Silurian Metasediments and Volcanics (SMV) aquifer, specifically the Oghill Formation, which is classified by the Geological Survey Ireland as a Poor Aquifer (PI). Poor aquifers are generally unproductive except for small, localised zones and are not considered regionally significant groundwater resources. Groundwater movement within this bedrock occurs predominantly through shallow fractured and weathered zones rather than through primary intergranular permeability. 4.3 Risk Assessment The potential contaminant source associated with the Proposed Development is limited to the importation of inert greenfield soil and stone for agricultural restoration purposes. No hazardous, biodegradable, contaminated, or chemically reactive materials will be accepted at the Site. Potential pathways considered include infiltration to groundwater through shallow subsoils and fractured bedrock, and surface runoff to nearby drainage features. Potential receptors include the underlying Poor Aquifer within the Cavan Groundwater Body and surface waters within the wider Rossollus Stream catchment. Given the inert nature of the imported material, the absence of hazardous substances, the Poor Aquifer classification, the relatively low recharge rate, and the absence of direct hydrological connectivity to surface water features, there is no credible mechanism by which contamination could occur. The proposed development does not introduce a significant pollutant source, and therefore the Source–Pathway–Receptor linkage is incomplete. Accordingly, the hydrogeological risk associated with the Proposed Development is assessed as low to negligible. The development will not result in deterioration of groundwater or surface water status and is consistent with the objectives of the Water Framework Directive.

Topsoil stockpiles will be kept away from drainage features, limited in height, and stabilised where necessary. Temporary surface water controls (silt fencing where required) will prevent sediment migration. No direct hydrological connection exists between the Site and surface waters. Importation of inert greenfield soil and stone Infiltration to groundwater Underlying Poor Aquifer (Cavan GWB) Low Risk. Only inert, uncontaminated greenfield soil and stone will be accepted. No hazardous or biodegradable material permitted. The Poor Aquifer classification and low recharge rate (51–100 mm/year) further limit risk. No infilling below groundwater level will occur. Importation of inert material. Accidental spill (fuel/oil from plant). Groundwater and surface water receptors Low Risk (with standard controls). Plant will be maintained in good condition. Refuelling will occur in designated areas with spill kits available on-site. Any spill will be contained and removed immediately.

Surface runoff will be controlled through grading and temporary measures during infilling. Importation of inert material. Surface water flow Underlying Cavan Groundwater Body Low to Negligible Risk. No credible pollutant source is present due to inert nature of material. The Source–Pathway– Receptor linkage is incomplete. Importation of inert material. Groundwater and the surface water flow. Designated sites No Risk. There are no SACs or SPAs within 15km of the Site and no hydraulic connectivity to any European Site. RECEIVED: 29/03/2026 Environmental Assessment 19 Operational Stage Source Pathway Receptor Risk Evaluation an Avoidance Restored agricultural use Surface runoff from reseeded grassland Local agricultural drains and wider catchment Low Risk. Following restoration, the site will be reseeded and returned to agricultural grassland. Vegetative cover will stabilise soils and reduce erosion risk. Surface runoff will reflect pre-development agricultural conditions. Restored land profile Infiltration to groundwater Underlying Poor Aquifer Low Risk. The inert fill increases soil thickness, potentially reducing groundwater vulnerability. No contaminants are introduced. No impact on groundwater quantity or quality anticipated. 4.4 Mitigation Measures The assessment of potential impacts on the receiving environment has taken account of embedded design measures and standard good construction practice to minimise risk to surface water and groundwater. The site slopes generally northwards, and all surface water receptors are located to the north of the site boundary. Accordingly, mitigation measures have been designed to prevent sediment or runoff migration in that direction. 4.4.1 Proposed Surface Water & Groundwater Mitigation Measures: Increased Runoff and Sediment Loading The following mitigation measures will be adopted: • Temporary silt fencing and/or sediment control measures will be installed along the northern boundary of the site to intercept any potential runoff before it can reach off-site drainage features. • A minimum buffer distance will be maintained between infilling activities and the northern boundary drainage direction. • Weather conditions will be considered when scheduling stripping, placement and grading activities in order to minimise exposed ground during periods of heavy rainfall. • Stockpiles of topsoil and subsoil will be located away from the northern boundary and managed to prevent erosion. Where required, stockpiles will be stabilised or covered. • Progressive grading and compaction of placed material will minimise loose exposed surfaces and reduce runoff potential. • Only inert, uncontaminated greenfield soil and stone will be accepted at the site. • Pre-approved source sites will be used to ensure that imported material does not contain pollutants, unauthorised waste, or invasive species. • No infilling will occur below groundwater level. • An emergency response procedure will be in place for accidental pollution events. • No unauthorised dumping of material will be permitted. Given that the site slopes northwards and surface water receptors are located in that direction, the northern boundary control measures represent the primary protection mechanism for surface water. RECEIVED: 29/03/2026 Environmental Assessment 20 4.4.2 Proposed Mitigation Measures for potential Oils and Fuel Spillages: To prevent accidental hydrocarbon contamination, the following measures will be implemented: • Refuelling of plant and machinery will take place in a designated area located away from the northern boundary drainage direction. • Where refuelling in situ is necessary, a double-skinned mobile fuel bowser will be used and a drip tray will be placed beneath the fill point. • Spill kits (including absorbent pads and booms) will be kept on-site at all times and operators will be trained in their use. • All plant and machinery will be inspected regularly for leaks. • No plant maintenance will be undertaken on-site. Any machinery requiring repair will be removed from the site. These measures ensure that no credible hydrocarbon pathway to groundwater or surface water exists. 4.5 Post Restoration Phase (Agricultural Use) Following completion of infilling works, the site will be restored to agricultural grassland and reseeded. The restored profi le will be stable and vegetated, significantly reducing erosion potential and surface runoff rates. Post-restoration land use will comprise low-intensity agricultural use, including: • Controlled fertiliser application in accordance with good agricultural practice. • Use of multi-species grass seed mixes to improve soil structure and reduce reliance on mineral fertilisers. • Maintenance of existing hedgerows to enhance biodiversity and stabilise field boundaries. • Livestock stocking rates maintained at sustainable levels. • No outwintering of cattle on the site. Once vegetative cover is established, runoff will filter naturally through grassed areas prior to leaving the site. Surface w ater flow will continue in a northerly direction consistent with existing conditions, and no change in runoff regime or water quality is anticipated. 4.6 Cumulative Hydrogeological Assessment The surrounding land use in the vicinity of the Proposed Development Site is predominantly agricultural in nature, comprising improved grassland and associated farming activities. Single rural dwellings are also present in the wider area. No industrial or large-scale waste management activities have been identified within the immediate hydrogeological zone of influence of the Site. The proposed development comprises the importation of inert greenfield soil and stone for agricultural restoration purposes. The activity is temporary in nature and does not introduce any hazardous or contaminating materials to the receiving environment. Given the limited scale of the development, the inert nature of the material, the absence of direct hydrological connectivity to surface water features, and the Poor Aquifer classification of the underlying bedrock, there is no potential for significant cumulative hydrological or hydrogeological impacts when considered in combination with other existing land uses in the area. Accordingly, no significant in-combination impacts on groundwater or surface water resources are anticipated. 4.7 Design Avoidance and Mitigation The assessment of potential impacts on the receiving environment has taken account of embedded design measures and standard good practice construction methods to minimise risk to the water environment. Buffer zones will be maintained along the Site boundaries, with particular emphasis on the northern boundary, as the Site slopes northwards and all surface water receptors are located in that direction. These buffer zones will ensure that no direct discharge to local agricultural drains occurs and that natural drainage patterns are maintained. RECEIVED: 29/03/2026 Environmental Assessment 21 The infilling works will be undertaken in accordance with standard pollution prevention guidance and good construction practice. Measures will focus on: • Control and management of surface water runoff; • Prevention of sediment migration during soil stripping and placement; • Management and verification of imported inert material; • Proper handling and storage of fuels and lubricants; • Immediate response procedures for accidental spills. No works are proposed within watercourses, and no alteration of existing drainage channels will occur. The natural surface water flow regime will remain consistent with existing conditions. 4.8 Water Quality There is a potential risk to water quality during the infilling phase, primarily associated with sediment runoff during heavy rainfall events or accidental fuel spillages from construction plant. Groundwater impacts are considered unlikely due to the Poor Aquifer classification of the underlying bedrock and the relatively low recharge rate in the area. The aquifer is characterised by limited productivity and localised fracture -controlled flow. As only inert, uncontaminated greenfield soil and stone will be accepted at the Site, no significant contaminant source will be introduced. In a worst-case unmitigated scenario, such as an accidental fuel spill or uncontrolled sediment runoff, there could be potential for localised impact to nearby drainage features located north of the Site. However, with the implementation of the proposed mitigation measures — including northern boundary sediment controls, buffer zones, proper refuelling procedures, and spill response protocols — such impacts will be prevented. The risk-based assessment has determined that, in the absence of mitigation, there could be a theoretical potential for impact to receiving waters. However, taking account of the embedded design measures and mitigation strategies outlined in this report, the proposed development will prevent or limit any potential deterioration of water quality. There will be no impact on the existing Water Framework Directive status of water bodies associated with the Site, including the Rossollus Stream and the underlying Cavan Groundwater Body, as a result of the Proposed Development RECEIVED: 29/03/2026 Environmental Assessment 22 5.0 Air Quality The Proposed Development comprises the importation of inert, uncontaminated greenfield soil and stone for the purposes of agricultural restoration. The activity does not involve the acceptance of biodegradable waste, hazardous materials, or organic matter capable of generating landfill gas, odour, or volatile emissions. 5.1 Construction Phase (Infilling Works) During the construction (infilling) phase, the primary potential air quality impact relates to the temporary generation of dust arising from plant movement, placement and grading of soil and stone material, and vehicle movements within the site. Any dust emissions are expected to be localised, intermittent, and short-term in nature. The site is located within a rural agricultural setting and is not situated within or adjacent to a densely populated urban area. Standard good construction practice will be implemented to minimise dust generation. Vehicle speeds within the site will be controlled, and haul routes will be dampened during prolonged dry weather if required. Material will be placed and compacted progressively to reduce the extent of exposed surfaces, and unnecessary double handling of soils will be avoided. In the event of exceptionally dry and windy conditions, works will be managed appropriately to prevent excessive dust generation. 5.2 Operational Phase (Post-Restoration) Upon completion of the infilling works, the site will be restored, topsoiled, and reseeded. Once vegetative cover is established, there will be no ongoing dust generation beyond that typically associated with standard agricultural land use in the area. No combustion processes are proposed, and no continuous emission sources will be present. On the basis of the scale and nature of the proposed development, and with the implementation of standard dust control measures, no significant adverse impacts on air quality are anticipated during either the construction or operational phases.

RECEIVED: 29/03/2026 Environmental Assessment 23 6.0 REPORT CONCLUSIONS Traynor Environmental has undertaken an Environmental Assessment of the Proposed Development at Binmore, Castleblayney, Co. Monaghan. The assessment considered the baseline environmental conditions at the Site, including the geological and hydrogeological setting, surface water characteristics, groundwater vulnerability, air quality considerations, Water Framework Directive (WFD) objectives, and the nature and scale of the proposed infilling activity. The Site is underlain by the Silurian Metasediments and Volcanics (SMV) aquifer (Oghill Formation), classified by the Geological Survey Ireland as a Poor Aquifer (PI). Recharge in the area is low to moderate (51–100 mm/year), and groundwater flow is localised and fracture-controlled. The Site lies within the Cavan Groundwater Body (IE_NW_G_061), which is currently assigned Good Status under the Water Framework Directive. There are no watercourses within the application boundary. Local agricultural drains are located approximately 60 metres north of the Site and flow northwards within the wider Rossollus Stream catchment. There is no direct hydrological pathway between the Site and these drainage features. No European designated sites (SACs or SPAs) are located within 15km of the Site, and no hydraulic connectivity to any such sites has been identified. The proposed development involves the importation of inert, uncontaminated greenfield soil and stone material for agricultural restoration purposes. No hazardous, biodegradable, contaminated, or chemically reactive materials will be accepted at the Site. The activity does not involve the disposal of waste containing organic matter, liquids, or pollutants capable of generating leachate, landfill gas, or odour emissions. The potential impacts on groundwater, surface water, and air quality have been assessed as part of this Environmental Assessment. The assessment concluded that the proposed development will not give rise to significant impacts on groundwater or surface water resources, and any temporary dust emissions associated with the construction phase will be minor, localised, and controlled through standard good construction practices. Following restoration, the Site will be reseeded and returned to low -intensity agricultural grassland. Vegetative cover will stabilise soils and reduce runoff potential. Agricultural management will follow good practice, including controlled fertiliser use and sustainable stocking densities. Based on the assessment undertaken, it is concluded that: • The Site is environmentally suitable for the proposed infilling of inert soil and stone; • There is no credible risk to groundwater quality or groundwater quantity; • There is no direct or indirect pathway to surface water receptors; • Potential air quality impacts during the construction phase will be temporary and minor in nature; • The development will not result in deterioration of surface water or groundwater status under the Water Framework Directive; and • No significant cumulative environmental impacts are anticipated in combination with existing land uses in the area. Accordingly, subject to the implementation of the mitigation measures outlined in this report, the Proposed Development will not give rise to significant adverse environmental effects on groundwater, surface water, or air quality during either t he construction (infilling) or operational (post-restoration) phases.
