Executive Summary and Introduction to the 2015 AER 1.1 Summary report on 2015 This Annual Environmental Report has been prepared for D , Belturbet, in County Cavan in accordance with the requirements of the wastewater discharge licence for the agglomeration. Specified assessments are included as an appendix to the AER as follows: Priority substances assessment The agglomeration is served by a wastewater treatment plant with a Design PE of 4,000. treatment process includes the following:- Preliminary treatment (screening and grit removal) Secondary treatment (activated sludge and anoxic tank) Chemical dosing for phosphorus removal The The final effluent from the Primary Discharge Point was non-compliant with the Emission Limit Values in The following parameter exceeded the emission limit values in 2015:- Ammonia 600,620 kgs of sludge, (total weight sludge, (wet)), (= 80,480 kgs Dry Solids), were removed from the wastewater treatment plant in 2015 as dewatered sludge cake. Sludge was transferred to Enva Storage Facility at Carrollstown Estate in County Meath.

25 1 Introduction This report has been prepared for D , Belturbet, in County Cavan in accordance with the requirements of Condition 6.8 / Schedule D of the wastewater discharge licence for the agglomeration. This desk top study has been undertaken to determine the necessity, if any, for analysis of the discharge to comply with the condition in the wastewater discharge licence based on the Guidance on the Screening for Priority Substances for Waste Water Discharge Licences, issued by the EPA. Relevant inputs to the waste water works and estimates of emissions from the discharge point have been taken into account in the preparation of this report. Relevant inputs to the waste water works, any relevant measurements / calculations / estimates of emissions from the discharge point and any relevant measurements undertaken at representative downstream monitoring locations have been taken into account in the preparation of this report. Details of the emissions concentration for the primary discharge and impact on the receiving water are included in Appendix Desktop Study 2.1 Assessment of Analysis Required A. Review of all industrial inputs into WWTP A review of all inputs into the wastewater treatment plant (WWTP) has indicated that there are no authorised industrial type discharges, unauthorised discharges with a likelihood of priority substances, leachate discharges or other imports. The wastewater influent to the WWTP is domestic in nature. B. Discharge monitoring The primary discharge has been analysed for priority substances. Analysis data is included in Appendix with details of the sample data and/or source of the data. Analysis data includes the full list of priority substances listed in the EPA s Guidance on the Screening for Priority Substances for Waste Water Discharge Licences. C. Downstream monitoring location s participation in relevant monitoring programme Any analysis data available for a representative downstream monitoring location from the discharge point for the relevant parameters is included in Appendix with details of the sample data and/or source of the data. D. Participation in PRTR reporting The PRTR is not required to be submitted for this agglomeration in Irish Water

26 2.2 Review outcome of Desktop study Full characterisation of the primary discharge has been achieved for all priority substances included in Appendix Priority substance concentrations were available for all parameters based on either analysis or the EPA PRTR toolkit. A review of the national monitoring programme for priority substances in wastewater is proposed to be undertaken by Irish Water in 2016 in consultation with the EPA. It is proposed that this review, in consultation with the EPA, will determine the scope of future Priority Substances monitoring at Irish Water WWTP s. 3 Assessment of Significance and Recommendations An assessment of the potential for impacts on receiving waters from priority substances in the primary discharge has been carried out. The assessment considers the primary discharge relevant to Environmental Quality Standards (EQS) for priority substances in surface waters, as set out in the European Communities Environmental Objectives (Surface Waters) Regulations 2009, as amended. No parameters have been identified as potentially being higher than the required EQS following dilution therefore no impact on the receiving waters is anticipated. Based on the assessment carried out it is not considered that any further sampling or analysis is required. The EPA have prepared a report on priority substances, An Inventory of Emissions to Waters in Ireland. This document states that Ireland appears to have relatively few problems associated with the presence of Priority / Priority Hazardous substances in its surface waters. It identifies that wastewater discharges are a potential source of metals in receiving waters with lead being the main metal identified as associated with wastewater discharges. However, metals exceedences, in particular those for cadmium, lead, and nickel are primarily associated with areas of historic mining activity. Similarly PAH s have been identified in stormwater overflows but the most significant source is considered to be rainfall. A consultation process with the EPA is proposed to be undertaken by Irish Water in 2016 to establish appropriate levels of monitoring for priority and dangerous substances, taking into account the particular requirements of the Water Framework Directive. This will allow a targeted monitoring programme to be undertaken in areas where priority substances have been identified or industrial discharges or imports provide a potential source, and where there is a shortfall of existing monitoring data. 2 Irish Water

27 Does the assessment use the Desk Top Study Method or Screening Analysis to determine if the discharge contains the parameters in Appendix of the EPA guidance Does the assessment include a review of licensed / authorised inputs to the works? Does the assessment include a review of other (unauthorised) inputs to the works? Does the report include an assessment of the significance of the results where a listed material is present in the discharge? (e.g. impact on the relevant EQS standard for the receiving water) Does the assessment identify that priority substances may be impacting the receiving water? Does the Improvement Programme for the agglomeration include the elimination / reduction of all priority substances identified as having an impact on receiving water quality? Desk Top Study and Screening Analysis Yes Yes Yes No No 3 Irish Water

32 Appendix Priority Substance Screening Flowchart A flow chart for the screening of the presence of organic compounds and metals (Priority Substances) from WWTP is included below. This flowchart shows that appropriate screening has been demonstrated in line with the assessment undertaken in this report. Full Characterisation Screening for presence of organic compounds and metals (priority substances) with regard to the parameters listed in Appendix 1 Depending on size of agglomeration / location carry out either one of the following: desktop study OR analysis of primary discharge Desktop study A. Review all industrial inputs including septic tank / package treatment plants and leachate to the WWTP B. Ascertain if discharge(s) is/ are part of any screening / monitoring programme C. Ascertain if a representative downstream monitoring point is part of any screening / monitoring point D. Ascertain if emissions data from WWTP calculated / estimated Review / outcome of desktop study Full characterisation Yes Appropriate screening demonstrated Scope and frequency of any subsequent monitoring to be agreed with the Agency viii Irish Water

33 Partial Characterisation Screening for presence of organic compounds and metals (priority substances) with regard to the parameters listed in Appendix 1 Depending on size of agglomeration / location carry out either one of the following: desktop study OR analysis of primary discharge Desktop study A. Review all industrial inputs including septic tank / package treatment plants and leachate to the WWTP B. Ascertain if discharge(s) is/ are part of any screening / monitoring programme C. Ascertain if a representative downstream monitoring point is part of any screening / monitoring point D. Ascertain if emissions data from WWTP calculated / estimated Review / outcome of desktop study Partial characterisation Undertake analysis for the outstanding parameters Revisit A above and undertake analysis of relevant parameters Analysis for outstanding parameters to be undertaken in 2016 to complete screening process Scope and frequency of subsequent monitoring to be agreed with the Agency ix Irish Water
