Core Refusal Reason
The proposed extension's scale and layout would increase wastewater loading on a site with poor drainage characteristics, violating EPA wastewater treatment guidelines and posing a risk to public health.
Decision Maker's Conclusion
- The scale and internal layout of the proposed extension, comprising additional bedrooms and living areas, would result in an unsustainable increase in loading on the wastewater treatment system.
- The subject site exhibits poor drainage characteristics as evidenced by the lack of recorded P-values in the EPA site characterization assessment reports.
- The development would be prejudicial to public health and is contrary to the 2009 and 2021 EPA Code of Practice guidelines for domestic wastewater treatment systems.

Decision Document Summary
The applicants sought planning permission for an 81.3 sq.m extension and alterations to an existing dwelling at Tullvealnaslee, Co. Galway, located approximately 1.8km northwest of Oughterard. This proposal follows a previous split decision on the site where a wastewater system was granted but an extension was refused. The current application was refused because the scale of the extension would increase occupancy and wastewater loading on a site with documented poor drainage.
