5361- Kilmainhamwood Compost Facility Extension- EIS comprises grey, laminated siltstones. This is succeeded by a red micaceous mudstone, including gypsum lenses, and coarse sandstone horizons towards the top. 7.3.3 Site Investigations Three monitoring boreholes were drilled within the site in March 2003 by Southern Pumps Ltd. The type of subsoil and bedrock described in the driller's logs (included in Appendix 7.1) supports the above description of geology in the area. Clay with gravel layers was reported to overlie Chalk. Based on the appearance of Chalk, it is assumed that the bedrock encountered was Gypsum, which would be typical of the geology in this region of Ireland. Trial pits were excavated at the site in October 2005. The associated trial pit logs are provided in Appendix 7.2. 7.3.4 Karst Features According to the GSI, there are no karst features within 5km of the proposed facility activity area. 7.4 SIGNIFICANT IMPACTS As the proposed changes to the facility do not involve any significant changes to the physical environment at the Thorntons Recycling composting site, there will be minimal impact on the geology of the underlying site. The extension and proposed administration building area are currently comprised of made-ground, with the exception of an area of approximately 0.3ha of planted woodland and landscaping surrounding the perimeter. For inspection purposes only. Consent of copyright owner required for any other use. Potential risks posed to the natural geological environment at the site include the storage of chemicals and fuels and the maintenance of vehicles, mobile and fixed plant equipment. If unmanaged, leachate from the incoming waste and the composting activities could infiltrate to ground and contaminate the underlying bedrock aquifer. The increase in waste to be stored and composted at the facility will not impact on the surrounding environment as this material will be processed as per current operational procedures in the existing and proposed extension buildings. 89 EPA Export 01-06-2010:03:55:55

5361- Kilmainhamwood Compost Facility Extension- EIS 7.5 MITIGATION MEASURES The facility is covered in made ground, with the exception of an area of landscaping along the perimeter of the site. Soil removed to facilitate construction will be retained within the site and used for landscaping purposes. All potentially polluting run-off from the composting process will be contained within the composting facility. A diesel tank is located on site. This tank is a double skin bowser with a capacity for 2,500 litres. To minimise any impact on the underlying subsurface strata and the groundwater from material spillages all waste oils, used spill kits, etc. used during operations will continue to be stored on a bunded pallet. All fuel loading will be carried within a bunded designated area within the facility building. Spill kits and pumping will be employed to deal with any spillages occurring within this bunded area. Spill kits will be retained on site to ensure that all spillages or leakages are dealt with immediately & staff trained in their proper use. Any servicing of vehicles on site will be confined to designated and suitably protected areas. The sites management system for quality, health and safety and environmental is certified to international ISO standards. Suitable mitigation measures are detailed with the management systems. 7.6 CONCLUSION As the site is currently covered in made ground, with the exception of an area of landscaping along the perimeter of the site, no impacts on the existing geological environment are predicted. For inspection purposes only. Consent of copyright owner required for any other use. With the correct environmental management at the site, there should be no adverse risk to the geological environment. 90 EPA Export 01-06-2010:03:55:55

7.5 MITIGATION MEASURES<br />

The <strong>facility</strong> is covered in made ground, with the exception of an area of landscaping along the perimeter<br />

of the site. Soil removed to facilitate construction will be retained within the site and used for<br />

landscaping purposes.<br />

All potentially polluting run-off from the <strong>compost</strong>ing process will be contained within the <strong>compost</strong>ing<br />

<strong>facility</strong>. A diesel tank is located on site. This tank is a double skin bowser with a capacity for 2,500 litres.<br />

To minimise any <strong>impact</strong> on the underlying subsurface strata and the groundwater from material<br />

spillages all waste oils, used spill kits, etc. used during operations will continue to be stored on a<br />

bunded pallet.<br />

All fuel loading will be carried within a bunded designated area within the <strong>facility</strong> building. Spill kits and<br />

pumping will be employed to deal with any spillages occurring within this bunded area.<br />

Spill kits will be retained on site to ensure that all spillages or leakages are dealt with immediately &<br />

7.6 CONCLUSION<br />

As the site is currently covered in made ground, with the exception of an area of landscaping along the<br />

perimeter of the site, no <strong>impact</strong>s on the existing geological environment are predicted.<br />
