Introduction

1.0 INTRODUCTION

1.1 Collooney Wastewater Treatment Plant.

The WWTP serving Collooney is located on Union Road, adjacent to the N4, it is an extended aeration plant which was designed to cater for a population equivalent of 1,400.

The older parts of Collooney are served by a combined system with newer areas of the town being served by a separate surface water drainage system. Pump stations at Knockbeg, Riverwalk, Highwood Park & Radharc Na hAbhainn pumps into the system.

The existing WWTP consists of Inlet Works Aeration Tank 2No. Sludge Beds Final Clarifier

There is also a storm water overflow facility from the treatment works, located at the inlet to the plant. In periods where there are large stormwater flows, flows above the design capacity of the plant overflows by weir to the Owenmore River.

Final Effluent Discharge from the treatment plant is to the Owenmore River (TPEFF2700D0093SW001) which runs adjacent to the treatment works via a 300mm discharge pipe ending in a flap valve.

1.2 Annual Environmental Report

This Annual Environmental Report (AER) has been prepared in accordance with the requirements of Condition 6.10 of the EPA Wastewater Discharge License No. D0093-01 issued on the 9th March 2011 for the Collooney Agglomeration & Schedule D of the said license reproduced below.

Note 2 Development/Infrastructural work summary (completed in previous year or prepared for current year). Any other items specified by the Agency.

Note 1: Content may be revised subject to the agreement of the Agency. Note2: This summary report shall provide detail on all measures proposed and undertaken by the Water Services Investment Programme for the agglomeration, including progress reports on infrastructural works and a statement of compliance with timeframes set out in this license.

This is the third AER to be submitted under the Collooney License issued 9th March, 2011.

1.3 2013 Summary

This AER was carried out in accordance with the EPA document “Guidance on the Preparation & Submission of the Annual Environmental Report for Waste Water Discharge Licenses for 2012” revision no.1, issue no.3 and in compliance with Condition 6 and Schedule D of the WWDL which sets out the contents required of the AER.

Monitoring Reports There was Seven (7) number compliance issues relating to this license for the 2013 reporting year, these related to 7no Ammonia, 1no T.S.S, 2 No. Orthophosphate ELV and 1 No. Suspended Solids exceedances (a record of which can be found in Section 3.2 Reported Incidents Summary

Operational Reports There were no complaints relation to the agglomeration in 2013 and all reportable incidents were made to the EPA via the online EDEN system as and when the incident was noticed.

Infrastructure Assessment & Programme of Improvements The SWO’s were inspected & assessed by Sligo County Council in January 2013 to determine compliance with the requirements of DoEHLG Document ‘Procedures and Criteria in relation to Storm Water Overflows, 1995’. Details of the inspection completed are included in Appendix 6, as per Part 4 The Sewer Integrity Assessment Toolset (Appendix vii) was completed and a risk assessment score of “Low Risk” was achieved. In order to further reduce this risk assessment scores the items within Section 4.2.1 will need to be addressed. The implementation of any outcomes from these assessments will be dependant Departmental funding and approval.

Environmental Liabilities & Financial Provisions The Owenmore River was assigned a biological quality rating of Q3 (Moderately polluted) at the upstream monitoring station and Q4 at the downstream monitoring station in 2009. The Owenmore River is classified as at risk of not achieving good status. The water body must maintain 'Good' status in order to comply with the Water Framework Directive (WFD). It is considered that management procedures already in place are adequate to maintain the discharge at a quality that complies with the license conditions and does not significantly impact on the sensitive environmental receptors. The plant caretaker/technician have implemented procedures which are continually reviewed to manage the identified risks at their current levels and to reduce them further in as far as is reasonable possible

License Specific Reports Based on the ‘Guidance on the Screening for Priority Substances for Waster Water Discharge License’, it can be concluded that when the analysis was compiled by City Analysts Limited in 2011 on behalf of Sligo County Council there were no elevated levels or exceedances of the Priority Substances as outlined in the European Communities Environmental Objectives (Surface Waters) (Amendment) Regulations 2012

Section II

Summary of Monitoring Reports

2.0 Summary of Monitoring Reports

2.1 Summary Report on Monthly Influent Monitoring.

Condition 4.15 of the WWDL states “The licensee shall carry out monthly monitoring of the influent stream to the waste water treatment plant for cBOD, COD, Suspended Solids, Total Nitrogen and Total Phosphorus in order to measure the mass loadings and removal efficiencies within the treatment plant.

Appendix 1 shows all Influent Monitoring Results for the year, together with all available daily flows.

2.1.1 Discussion of Influent Monitoring Results

Table 1 shows an average Influent flow of 347m3/day (4l/sec) over the year and an average influent BOD of 326mg/L, this equates to a BOD load of 113 Kg/day and a population equivalent of 815 (@ 60g BOD/hd/day).

The below Table outlines the average, minimum & maximum results for the year, 2013

Infrastructural Assessments & Programme of Improvements

4.0 Infrastructural Assessments & Programme of Improvements

4.1 Storm Water Overflow Identification & Inspection Report

As per condition 4.12.1 of the License “The licensee shall, prior to the date for submission of the second AER (required under Condition 6.10), carry out an investigation for the identification and assessment of storm water overflows. A report on the storm water overflows shall be submitted to the Agency as part of the second AER. The assessment shall include a determination of compliance with the criteria for storm water overflows, as set out in the DoEHLG ‘Procedures and Criteria in Relation to Storm Water Overflows’, 1995 and any other guidance as may be specified by the Agency.

There are 3No. Storm Water Overflows (SWO’s) identified in the WWDL. SWA located at the inlet works to the Treatment plant, flows above the peak flow to the treatment plant overflows by weir to a 300mm pipe. This overflow rejoins the treated effluent line prior to discharge to the Owenmore River. SW2, located on the Dublin Road, adjacent to Mangans Cash & Carry this overflows on a regular basis during heavy rain SW3, this is located on the old Dublin road adjacent to Collooney Bridge. According to the Caretaker this has never overflowed.

These SWO’s were inspected & assessed by Sligo County Council in January 2013 to determine compliance with the requirements of DoEHLG Document ‘Procedures and Criteria in relation to Storm Water Overflows, 1995’. Details of the inspection completed are included in Appendix 6, as per Part 4 ‘Assessment Criteria for Existing SWO’s’.

These SWO’s would activate rarely, only after prolonged periods of rainfall, possibly seven to eight times per year.

4.2 Report on Progress made and Proposals being developed to meet the Improvement Programme Requirements.

Condition 5.1 of the license states ‘The licensee shall, as a part of the second AER required under Condition 6.10), prepare and submit to the Agency a programme of infrastructural improvements to maximise the effectiveness and efficiency of the waste water works in order to: a) achieve improvements in the quality of all discharges from the works; b) meet the emission limit values specified in Schedule A: Discharges, of this licence; c) give effect to Regulation 2 of the Waste Water Discharge (Authorisation) Regulations 2007, as amended; d) reduce Total Phosphorus loadings in the discharge to the maximum practicable extent; e) meet the obligations of Condition 1.7

Under Schedule C, there are two number of specified improvements identified to be carried out.

C.1 - Improvement Programme for Primary Discharge Any works required to reduce BOD & Orthophosphate levels to meet the ELV specified in Schedule A1; Primary Waste Water Discharges of this License, this has a completion date set for 31st December 2015.

The aerator was upgraded from a 7.5 to 15Kw new motor, VSD and surface aerator in June of 2013 to address higher organic loading and ammonia non compliance. This action had a positive impact on the ammonia results bring the plant under the ELV from August to end of year.

Condition 5.2(a) – The Waste Water Treatment Plant

5.2(a)(i) the existing level of treatment, capacity of treatment plant and associated equipment As per table 2 of this AER, the existing level of treatment is achieving effective removal of the ELV parameters as set out in the License, with one exception, Ammonia. A new aerator, larger 15 Kw motor and larger VSD was installed in June of 2013 and has addressed this item.

5.2(a)(ii) The ELV as specified in Schedule A: Discharges of the License As per table 2 and section 3.2 of this AER, there were 6no of incidents reported in 2013, a Waste Water Maintenance Contract has now been put in place which requires all mechanical end electrical equipment to be serviced bi-annually, this in combination to the works outlined above should eliminate some of the exceedances.

5.2(a)(iii)Designations of the receiving water body As per Section 5.1.4 & Table 16 of this AER, the Owenmore River was assigned a biological quality rating of Q4 (Moderately polluted) at the upstream monitoring station and Q4 (Unpolluted) at both the upstream & downstream monitoring stations in 2009. The Owenmore River is classified as at risk of not achieving good status. The water body must maintain 'Good' status in order to comply with the Water Framework Directive.

5.2(a)(iv)Water quality objectives of the receiving water body. Every effort will be made to implement any improvement works that may be required as outlined in Appendix vii, Table 4 Statement of Measures subject to approval and availability of funding.

Condition 5.2(b) – the Integrity of the Waste Water Works

5.2(b)(i) Capacity of the waste water works As per section 2.4 of this report there is an average of 598m3/day spare capacity at the plant.

5.2(b)(ii) Leaks from the waste water works

5.2(b)(iii) misconnections between foul sewers and surface water drainage network. The older parts of the network are served by a combination system with the newer areas of the town being served by a separate surface water drainage system. A pump station at Knockbeg pumps into the system

5.2(b)(iv) infiltration by surface water

5.2(b)(v) infiltration by groundwater

Condition 5.2(c) – Storm Water Overflows It is envisaged that in 2013, meters will be installed on the SWO’s to calculate the quantity of overflow and the frequency of the overflow occurring, this work will be dependant on approval and budgets.

Condition 5.2(b) of the license states “The programme of infrastructural improvements referred to in Condition 5.1 shall include an assessment of the integrity of the waste water works having regard to: (i) capacity of the waste water works; (ii) leaks from the waste water works; (iii) misconnections between foul sewers and surface water drainage network, (iv) infiltration by surface water; (v) infiltration by groundwater; (vi) such other aspects of the works as may be specified by the Agency”

The completed Sewer Integrity Assessment tool can be found in Appendix vii, a summary of the Risk Assessment Scores can be found in the table below.

Table 12: Sewer Integrity Risk Assessment Improvement Programme (Works) The Improvement Programme should Risk Risk Assessment Reference to include an assessment of the integrity of the Assessment Score relevant section existing wastewater works for the following: Rating of AER Hydraulic Risk Assessment Score High 110 4.2.1(a), Appendix vi Environmental Risk Assessment Score Low 245 4.2.1(b), Appendix vi Structural Risk Assessment Score High 150 4.2.1(c), Appendix vi O&M Risk Assessment Score Low 8 4.2.1(d), Appendix vi Overall Risk Assessment Score for the High 583 agglomeration

4.2.1(a) Hydraulic Risk Assessment

Upon completion of the Hydraulic Risk Assessment a High Risk rating was achieved, in order to reduce this risk rating to a Medium/Low the following items will be required Hydraulic Performance Assessment of the Network & implementation of any outcomes. A manhole survey of the network to comply with WRc Documentation. A flow survey of the network to comply with WRc Documentation.

When these assessments have been completed the list of defects (if any) will be required to be prioritised with regard to their short, medium and long term affect on the network. The implementation of any outcomes from these assessments will be dependant Departmental funding and approval.

4.2.1(b) Environmental Risk Assessment

A Low Risk Assessment Rating has been achieved for this assessment, in order to reduce the risk assessment score the agglomeration can be further monitored so as to not release any discharges that may cause any environmental pollution of the receiving waters.

4.2.1(c) Structural Risk Assessment

A High Risk Assessment has been achieved for this assessment, to reduce this risk rating a CCTV survey of the network will be required to determine any defects/deterioration of the network. When this assessment has been completed the list of defects (if any) will be required to be prioritised with regard to their short, medium and long term affect on the network and funding sought for their remedy. The implementation of any outcomes from these assessments will be dependant Departmental funding and approval.

4.2.1(d) O&M Risk Assessment

A Low Risk Assessment Rating has been achieved for this assessment

6.1 Priority Substance Assessment

As per condition 4.11.1 of the License ‘A representative sample of effluent from the primary discharge point shall be screened for the presence of organic compounds and metals within six months of the date of grant of this license. The list of parameters for analysis shall include, as a minimum, those organic compounds and metals identified as relevant having regard to the European Communities Environmental Objectives (Surface Waters) Regulations 2009 and any other relevant legislation. Such screening shall be repeated at intervals as requested by the Agency thereafter’

Condition 4.11.2 of the License states ‘The licensee shall, within twelve months of the date of grant of this license, investigate the sources of dangerous substances detected during monitoring of the primary discharge and take such measures as are necessary to comply with the European Communities Environmental Objectives (Surface Waters) Regulations (S.I. No. 272 of 2009) for the discharge of such substances from the waste water works. A report on the investigation and measures identified, including timeframe for implementation, shall be included in the AER.’

Based on the ‘Guidance on the Screening for Priority Substances for Waster Water Discharge License’ document a risk based approach should be undertaken when addressing the screening requirement at the primary discharge. The Ballymote agglomeration (<2,500p.e) serves a small rural village compromising primarily of domestic dwellings, schools, commercial units, community centre and a church. There are no industrial inputs to the treatment plant. It can be concluded from this desktop overview that there is no further screening necessary or required for organic compounds or metals. Furthermore, in 2011 when the analysis was compiled by City Analysts Limited on behalf of Sligo County Council there were no elevated levels or exceedances of the Priority Substances as outlined in the European Communities Environmental Objectives (Surface Waters) (Amendment) Regulations 2012.

A copy of the analysis as undertaken by City Analysts Ltd can be found in Appendix ix

Appendix VI

Storm Water Overflow Inspection Reports Assessment Criteria

Discharge Point Code SWA – Inlet to Treatment Plant

SWA located at the inlet works to the Treatment plant, should the flow to the inlet works exceed the design capacity (6DWF) overflow will take place. This overflow from the inlet chamber will then rejoin the treated effluent pipeline prior to discharge.

This SWO complies with the ‘Procedures & Criteria in relation to Storm Water Overflows’ 1995 as follows: 1. Does the Storm Water Overflow cause significant visual or aesthetic impact and public complaints? NO, the SWO is situated at the inlet to the plant, located in a manhole.

2. Does the SWO cause deterioration in the water quality in the receiving water? NO, as the storm overflow is only in operation during storm events it is estimated that the dilution to the untreated effluent is large enough so as to not cause any deterioration to the receiving water.

3. Does the SWO give rise to failures in meeting the requirements of national regulations on foot of EU Directives (Bathing Waters, etc.)?

NO

4. Does the SWO operate in Dry Weather? NO, only in storm flows

As per the above, it’s deemed that the SWO (SWA) is in compliance with the requirements of DoEHLG Document ‘Procedures and Criteria in relation to Storm Water Overflows, 1995’

It is the intention of Sligo County Council to install a flow meter to determine the number of storm overflows and quantity of storm released to the waterbody throughout the year

The License sets out in Schedule C.2: Improvement Programme for Storm Water Overflows that this Overflow requires an upgrade in order to comply with the criteria outlined in the DoEHLG “Procedures & Criteria in Relation to Storm Water Overflows, 1995”.
