No lakes. Status elements Q score dictates status in all but one monitored WB, where Hydromorph and Fish bring it down from High to Good (Little Slaney River). Phys Chemical status is high where monitored. Status was extrapolated for 7 good WBs. Chemical status passes where monitored (1 water body, Slaney River main channel) Possible Impacts EPA Water Quality 2004 Brown’s Beck Brook - (SE_12_825 - Good); Major improvement but presence of filamentous algae indicative of nutrient enrichment. Carrigower - (SE_12_1535 - Moderate); Distinctly over-enriched at Merginstown bridge in 2007. Sewage and Agriculture suspected. Slaney - (SE_12_1524 - Good); Upper reaches of Slaney in this WMU are at Good ecological condition. High 8% 8% Good Moderate Poor Bad Yet to be determined 84% PRESSURES/RISKS Nutrient sources 84% of TP is Diffuse, 78% of which is from Agriculture. 16% of TP comes from WWTP. Point pressures 5 WWTP (Rathvilly, Tullow, Baltinglass, Donard, Stratford); 3 WTP (Knockanarrigan, Tullowphelim, Rathvilly); 4 Section 4s - fish farm, DoD, Private Company, Army Camp. 3 EPA Licensed Waste Facilities Wastewater Treatment Plants (WWTP) and Industrial Discharges WWTP’s at Risk: Rathvilly Tullow WWTP Baltinglass 1 WWTP 1 section 4 - at risk from existing and future insufficient assimilative capacities for BOD and Nutrients. Quarries, Mines & Landfills 14 Quarry, 2 Landfills, no waterbodies at risk Agriculture Small area of WMU at risk - low-lying areas to the west of the WMU. On-site systems There are 2239 septic tanks in this WMU, none of them are posing a risk to water quality due to their density, location and unsuitable hydrogeological conditions. Forestry No waterbodies at risk from forestry. Knickeen and Little Slaney will more than likely deteriorate during and after felling. Dangerous substances No waterbodies at risk from Dangerous Substances. Morphology No waterbodies at risk. ERFB comment (060509) that most of the Carrigower has been altered in the past and there is regular maintenance / deepening of a significant section in the Merginstown Area. Also an impassable Structure on The N81 Br. over the Tuckmill Trib (12_1728) – a concrete apron with a significant drop. Abstractions 13 abstractions - 1 risk (SE_12_1398) Other None Slaney Upper Water Management Unit Action Plan SELECTED ACTION PROGRAMME NB All relevant basic measures, general supplementary measures and SEA mitigation measures apply Point Sources OBJECTIVES Good 2015 status 1 water body WWTP – refer to Table below INDUSTRY Examine the terms of discharge authorisations to determine whether they require review for the purpose of compliance with water body objectives including protected area objectives and environmental quality standards. Diffuse Sources AGRICULTURE - Good Agricultural Practice Regulations and Enforcement. Other OTHER Protection of drinking water, abstraction control and future licensing. Protect 12 water bodies Alternative Objectives Extended Deadlines – none New Modifications or Development – Tullow flood alleviation feasibility study underway. HMWB/AWB - none FUTURE DEVELOPMENT Future Pressures and Developments Point Source Discharge Throughout the river basin management cycle future pressures and developments will need to be managed to ensure compliance with the objectives of the Water Framework Directive and the Programme of Measures will need to be developed to ensure issues associated with these new pressures are addressed.
