Annual Environmental Report 2011 Roscrea Agglomeration

Roscrea Agglomeration was issued with a Waste Water Discharge Licence on 6/11/08. Licence Register Number D0025-01. This is the Annual Environmental Report (AER) for 2010 as required under Condition 6.10 of said Licence. It contains the information required under Schedule D of the Licence.

1. Discharges from the agglomeration

Roscrea Agglomeration uses the same primary discharge point, emergency overflows and stormwater overflows as identified in the Waste Water Discharge Authorisation Licence Application which was lodged with the EPA in December 2007, except that the SWO at Castle Street (SW2) has been eliminated. The primary discharge point was sampled 12 times in 2011 (All Composite Samples).

Most samples taken of the primary discharge in 2012 were within the Emission Limit Values (ELV) for Roscrea as set out in Schedule A of the Licence, except most samples exceeded the ELV for Total Nitrogen

Please find attached an Excel Spreadsheet called “Appendix No.1 Roscrea WWTP Final Effluent Test Results 2011” attached. This spreadsheet shows all samples taken for Roscrea WWTP’s Final effluent in 2011.

The ELV in the Licence for Total Phosphates is 1 ppm. This is 50% less than the limits imposed on discharges to Sensitive Waters under the Urban Wastewater Treatment Directive. The longer term ELV of less than 0.5 ppm will be challenging to achieve. Roscrea Agglomeration receives industrial wastewater and the ELV in this licence may require a review of discharge licences from industrial units into Roscrea Agglomeration. The Total Nitrogen requirement of 15mg/L is very challenging to achieve for Roscrea WWTP as its secondary treatment is in the form of trickling bio filters.

2. Summary report on monthly influent monitoring and loading removal efficiencies2.(i) In 2011, 12 No. influent samples were taken at Roscrea WWTW, at

approximately monthly intervals. Please find attached an Excel Spreadsheet called “Appendix No. 2(i) Roscrea WWTP Plant Influent Test Results 2011” (This spreadsheet shows all test results for samples taken for Roscrea WWTP Influent in 2011.)

2(ii) Please find attached an Excel Spreadsheet called “Appendix No. 2(ii) Summary Report on Loading Removal Efficiencies at Roscrea WWTW 2011” (which gives a breakdown for all the parameters mentioned in Schedule A:A.1). In 2011, 12 No. composite samples were taken at Roscrea WWTP. Composite Final effluent samples were also taken on the same day. By comparing the percentage reduction of the relevant parameter in the effluent samples, the loading removal efficiencies could be estimated.

3. Data collection and reporting requirements under the Urban Waste Water Treatment DirectiveRoscrea Agglomeration’s WWTP is included in North Tipperary County Council’s 2011 Annual Urban Wastewater Treatment Returns Report to the EPA. This report was lodged by North Tipperary County Council with the EPA by 26 February 2011.

4. Complaints summaryThere have been no environmental complaints about Roscrea Agglomeration in 2011.

5. Pollutant Release and Transfer Register- report for previous yearA Pollutant Release and Transfer register for has been completed for Roscrea Agglomeration for the year 2011. This report has been submitted electronically, and is also included in this AER.

6. Pollutant Release and Transfer register- report for current yearThere is no expected change from the 2011 PRTR for 2012.

7. Ambient monitoring summaryIn 2011, ambient sampling consisted of 12 grab samples taken (i) upstream and (ii) downstream of the primary discharge point. Please find attached 2 No. Excel Spreadsheets called “Appendix No. 7(i) Roscrea WWTP Upstream Test Results 2011” and “Appendix No. 7(ii) Roscrea WWTP Downstream Test Results 2011” attached. These spreadsheets show all test result values for samples taken upstream and downstream of Roscrea WWTP’s Primary Discharge Point in 2011. The ambient monitoring samples were compared to the criteria for calculating surface water ecological status and ecological potential as set out under Schedule 5 of the European Communities Environmental Objectives (Surface Waters) Regulations 2009. The grab sample upstream of Roscrea WWTP, was classified as having a “less than good” water status, by comparing the Total Ammonia, BOD and Orthophosphate parameters to the parameters set out in Schedule 5. Similarly, the grab sample taken downstream classified as having a “less than good” water status, by comparing the Total Ammonia, BOD and Orthophosphate parameters to the parameters set out in Schedule 5. The discharge does not appear to have any adverse effect on the Little Brosna River.

8. Storm water overflow inspection and assessment reportNo Storm water overflow inspection and assessment report has been completed in 2011. It is expected to be completed in the coming years. These stormwater overflows only perform in stormwater conditions.

9. Storm Water Overflow assessment of compliance (every 3 years)No Storm Water Overflow assessment of compliance has been completed in 2011. It is expected to be completed in the coming years.

10. Reported incidents summaryThere was one reported incident to the EPA in Feb 2011. This related to an Ammonia ELV exceedence.

11. Report on progress made and proposals being developed to meet the improvement programme requirements.

North Tipperary Co. Council is currently reviewing its options with regard to licensed discharges into Roscrea Agglomeration’s sewer network, which are currently affecting the Council’s capacity to fully comply with the conditions of this licence, particularly the parameters of total nitrogen and ammonia.

At present a Brief for Engagement of a Consulting Engineer for the Roscrea Sewerage Network Upgrade is being prepared by North Tipperary County Council’s Water Services Section. The Consultant appointed will be required to carry out an investigation into Roscrea Sewerage Scheme and prepare a preliminary report. This Capital Programme is part of North Tipperary County Council’s Water Services Investment Programme which is based on North Tipperary County Council’s Water Services Assessment of Needs Report. This project proposes to assess and identify deficiencies in the existing sewerage and storm water collection network and to upgrade the network to cater for the development of Roscrea Agglomeration over the next 50 years. The report will 1. Recommend a phased approach to the collection system construction, as

necessary to meet the short term, intermediate and ultimate design life of 50 years.

2. Provide for separate foul and storm sewers, upgrading deficient sewers and built new sewers as required.

3. Submit proposals for minimizing storm flows and dealing with any infiltration to the existing foul system.

4. Review existing pumping stations and identify the need for future pumping stations.

5. Conduct flow and load surveys on the existing network. 6. Conduct CCTV surveys on the existing network. 7. Make recommendations on the upgrade of the SCADA/telemetry systems for

the collection system. It is expected this preliminary report will identify sewer sections that are currently at capacity. These will be replaced with sewers with increased capacity. Older, damaged sewers will be replaced to prevent groundwater infiltration and storm water overflows will be assessed and eliminated if possible.

12. Development/Infrastructural works summary (completed in previous year or prepared for current year)In 2011, no major infrastructural development was completed. In 2012, no major infrastructural development is expected to be completed.

13. Statement of measures required to prevent environmental damage under Environmental Liabilities Directive (2004/35/EC)It is the goal of North Tipperary County Council to prevent environmental damage under Environmental Liabilities Directive (2004/35/EC). North Tipperary County Council has completed an Environmental Liabilities Risk Assessment to address the liabilities from present or planned discharges. North Tipperary County Council is currently in negotiation with an insurance company in order to put in place financial provisions in relation to the underwriting of costs for remedial actions following anticipated events or

��

accidents/incidents, as may be associated with discharges or overflows from the waste water works. The details of the financial provision/insurance will be submitted to the Agency as soon as they are completed.

14. Assessment of predicted impact on habitatsIt is expected that Roscrea Agglomeration will have no significant adverse impact on habitats into which it discharges.

15. Toxicity TestingToxicity testing was carried out in 2009 on Roscrea WWTW’s final effluent and it was confirmed to be non-toxic. On 8/11/2010, Susan Howley, Inspector, Office of Environmental Enforcement, wrote to Mr. Jim McGuire, Senior Engineer, Water Services, North Tipperary County Council.(EPA Ref: D0027-01/gc02sh.docx.) In this letter, she stated that repeat toxicity testing for Roscrea WWTW was not required, unless there is a material change to, or increase in, the licensed discharge. No material change has occurred at Roscrea WWTW since toxicity testing was first carried out, and as a result, no toxicity testing was carried out in 2011.
