R21 = Acceptable subject to normal good practice. Site may be suitable for discharge to ground, if the minimum depths are met on the site and if there exists suitable percolation. As the soil type in the area is Acid Brown Earths (75% of the land area), and as the area is mapped as ‘Extreme’ Vulnerability. Groundwater as a resource will be at risk if the minimum depths required are not achieved on the site, or if the percolation rate is too rapid. Older wells in the area may also be at risk, if the minimum separation distances are not adhered to. Groundwater and wells are therefore the main targets, following the desk study. Given the response and the aquifer type, the site is potentially suitable for a conventional septic tank system if the minimum depths required are met on the site, if the minimum separation distances can be met, and if the percolation rate is adequate. ____________________________________________________________________________________ 1This figure of 6 people refers to the potential 6 people maximum that will stay at the proposed dwelling at any one time.

Existing Land Uses Agricultural Grassland Vegetation Indicators Grass is the predominant vegetation in the ppa Groundwater Flow Directions Northeast Direction Ground Condition Ground conditions are best described as firm in the ppa . Site Boundaries Lane and hedge are located to the North and West of the ppa. Roads Local road located >240m east from the ppa. Outcrops (Bedrock and/or subsoil) None Identified or Evident within the locality. Surface water ponding No surface water ponding was evident in the ppa when examined on 05.06.25. It must be noted that weather conditions prior to the site assessment taking place was generally dry & firm conditions. Lakes None occur within 50m of the ppa. Beaches/Shellfish Areas None occur within 200m of the ppa. Wetlands None occur within 200m of the ppa. Karst Features None occur within 200m of the ppa. Watercourses/Streams None occur within 10m of the ppa. Drainage Ditches None occur within 10m of the ppa. Springs None occur within 50m from the ppa. RECEIVED: 25/07/2025 5 Wells Existing water supply taken from mains water. As all the wells in the locality will therefore meet the required separation distances of the Groundwater Protection Responses of GSI/EPA/DoELG and the EPA Code of Practice (2021), none are deemed to be at risk from the proposed polishing filter’s installation. Integrate the information above in order to comment on: 1. The potential suitability of the site: The site still seems suitable for discharge to ground. 2. Potential targets at risk: Following the desk study surface water was thought not to be at risk; this was corroborated during the visual assessment. There appears to be few issues with respect to impermeability. From this, surface water does not seem to be a potential target, Groundwater is still a target following the visual assessment, unless the minimum depths required are met on the site and there exists adequate percolation. 3. The suitability of the site to treat the wastewater: Following the visual assessment it is seen that all appropriate separation distances can be met and the site seems well drained, and pending confirmation of the presence of adequate depths of unsaturated soil and subsoil within the percolation area, as well as sufficient percolation rates under the site, the site should be suitable for treating wastewater adequately.

Wastewater Treatment system description: The Oakstown BAF 8 PE is designed to provide proven, cost effective primary and secondary wastewater treatment in robust steel reinforced concrete tanks. The primary sedimentation chamber has substantial capacity (4m³) to allow anaerobic digestion to occur naturally while letting sludge settle on the tank floor. Once primary treatment has taken place the effluent is further degraded in the aeration chamber where oxygen enriched wastewater provides ideal conditions for aerobic bacteria to thrive. Before pumping to the percolation area the clear water is left to further settle in the clarifier chamber to eliminate any remaining settle able solids. 3. Guarantee and warrantees: O’Reilly Oakstown provide a 12 month maintenance service contract on all systems from date of first occupation. We provide a 24 month warranty on all parts. 4. Percolation: The percolation area designed must conform to the requirements of Table 10.1 of EPA Code of Practice 2021 Wastewater Treatment and Disposal System serving single houses. The percolation area requirements are as follows: Sub Surface value 70.82min/25mm as per Site Characterisation Form. Surface value: 53.79min/25mm as per Site Characterisation Form. Depth from ground surface to water table: 0.8BGL Depth from ground surface to winter groundwater level: 0.7BGL Depth from ground surface to bed rock: None Encountered Percolation Area: As per Traynor Env Report ►See Site Characterisation report for percolation area details .
