Section A: Non-technical summary 1. Introduction Clare County Council is required to make an application to the Environmental Protection Agency (EPA) for a licence to discharge treated wastewater from the wastewater treatment plant (WWTP) at Ballykinncorra North, serving the Corrofin agglomeration, in accordance with Article 5 of the Wastewater Discharge (Authorisation) Regulations, 2007 (S.I. No. 684 of 2007), on or before the 22nd of June 2009. The application form and its attachments are completed as required by the EPA in accordance with guidance notes provided. 2. Description of Corrofin Corrofin is located on the southernmost edge of the Burren, approximately 14 kilometres north-west of Ennis on the R476 and approximately 24 kilometres south of Ballyvaughan. Corrofin is situated along the banks of the River Fergus, which forms part of the East Burren wetlands supporting a large variety of flora and fauna, with many lakes, turloughs and fens. Corrofin has experienced an increase in housing development in recent years and is also subject to variation in the population loading for summer and winter due to tourism impacts. A map indicating an aerial view of the existing and proposed agglomeration catchment for the Corrofin WWTP, the location of the Corrofin wastewater treatment plant, primary discharge and stormwater overflow points and ambient sampling points is provided as Attachment B-1. 3. Wastewater sources Domestic wastewater is the main component of discharge to the Corrofin wastewater treatment plant, with a proportion of commercial in the form of B&B facilities and small commercial businesses. The majority of homes and businesses are served by the foul system, which works by gravity only flowing towards the treatment works and River Fergus.There is no industrial activity in the village. 4. The Wastewater Treatment Plant (WWTP) The existing Corrofin WWTP, which was constructed in the 1950’s, is located to the east of the village along the southern banks of the River Fergus. The treatment works site is part of the floodplain of the River Fergus and supports a mix of wet grassland of some ecological value and improved grassland. The design population for the existing Corrofin WWTP is 550 PE, however the treatment plant is overloaded and in poor state of repair. In accordance with Clare County Council’s Water Services Investment Programme 2007-2009, Ballyvaughan, Doolin & Corofin are a bundled scheme with a projected cost of €18,025,000. Following approval of a Brief by the Department of the Environment Heritage and Local Government, and compliance with procurement processes, P H Mc Carthy & Partners were appointed to prepare a preliminary report. PJ Tobin & Co, Consulting Engineers were appointed as Consulting Engineers on 30th December 2002 for the project. Land adjacent to the existing WWTP has been acquired for the proposed new wastewater treatment plant. The project commenced in 2008 and the network is near completion. The contract for the new wastewater treatment plant has been signed and

the contractors are due to submit a final design before construction works commence in 2009. The initial proposal for the Corrofin WWTP scheme included the provision of pumping stations on the networks system, however following a review of the scheme, the revised proposals include provision of a collection system to serve only the core of the village, and any sewers and pumping stations outside this core area will be constructed in future schemes as the need arises. Due to the condition of the existing wastewater treatment facilities, the proposed treatment works will not incorporate the existing treatment units. In the Preliminary Report carried out by PH McCarthy & Partners in November 2000, the population for Corrofin being served by the WWTP was estimated as 492 during the winter reaching a maximum of 878 in the summer period. The design population for the proposed Corrofin WWTP is 1725 PE, which takes into account a 20 year design horizon as set out in Table 1 hereunder. Provision is in place for expansion should the population demand an increase. Table 1: Design data for proposed Corrofin WWTP Design Load 1725 PE DWF 804 m3/day BOD5 Load 103.5 kg/day DWF taken from Preliminary Report by PH McCarthy & Partners in November 2000 The above design was based on previous definitions of population equivalent and dry weather flow, with 60grms BOD5 and 225 litres flow per head per day. Under the Waste Water Discharge (Authorisation) Regulations, 2007, the calculation of population equivalent is based on the maximum average weekly flow entering the wastewater works during the year and measurement of organic biodegradable load for this flow, allowing 60g of BOD5 per head of population. 5. Treatment Process Description Corrofin WWTP consists of the following elements:

Inlet screening, fitted with screening removal and bypass Imhoff tank Sludge Drying Beds

5.1 Inlet Screening Incoming wastewater is directed through coarse bar screens to remove solids. The screenings are removed manually. A storm overflow is provided, however it rejoins the treated flow before discharging to the River Fergus. 5.2 Imhoff Tanks Wastewaters are treated in the Imhoff tanks before discharging to the River Fergus via an 225mm diameter concrete pipeline. A site layout map is provided as Attachment B.2 and the map indicating both the location of the treatment plant and the main discharge point to surface water is provided as Attachment B-1. The treated wastewater discharge is the primary discharge, and is designated (P)SW1 on the maps accompanying the application. There is no storm water overflow facility from the Corrofin WWTP. 5.7 Sludge Management The Imhoff tanks are desludged periodically and the sludge is removed to the sludge drying beds.

6. Wastewater Flow volumes The collection system serving the Corrofin WWTP consists of separate foul and storm water collection systems. Flow data for the WWTP is not available. In the Preliminary Report carried out by PH McCarthy & Partners in November 2000, the population for Corrofin being served by the existing WWTP was estimated as 492 during the winter reaching a maximum of 878 in the summer period. This equates to an approximate hydraulic loading arriving at the Corrofin WWTP of 111m3/day (winter) and 197m3/day (summer). These measurements are used to estimate the final population equivalent, based on the average influent BOD values between May 2007 and March 2009, - 264 mg O2/litre BOD. The population equivalent for this loading is 488 PE (winter) and 866 PE (summer). This approach to estimation of population equivalent is in accordance with the definition provided in the Waste Water Discharge (Authorisation) Regulations, 2007 (“population equivalent” is a measurement of organic biodegradable load and a population equivalent of 1 (1 p.e.) means the organic biodegradable load having a five-day biochemical oxygen demand (BOD5) of 60g of oxygen per day; the load being calculated on the basis of the maximum average weekly load entering the waste water works during the year, excluding unusual situations such as those due to heavy rain). 7. Combined storm overflows A storm overflow facility is provided at Corrofin Bridge. The storm overflow facility at Corrofin Bridge discharges to the River Fergus just west of the bridge. Samples of the river were taken during the preparation of this application and results of this exercise are set out in Table F.1 (ii) a of the application form. This storm overflow will be decommissioned on completion of the construction of the new WWTP proposed for Corrofin. 8. Impact of emissions from the Corrofin WWTP on the River Fergus The impact of discharges from the Corrofin WWTP on the receiving waters of The River Fergus is considered under a number of headings:

8.1 Description of receiving waters 8.2 Statutory Designations of the Receiving Waters 8.3 Assimilative capacity of the receiving waters 8.4 Total maximum nutrient load discharging to receiving waters 8.5 Monitoring undertaken on receiving waters 8.6 Impact of storm overflows

8.1 Description of receiving waters The Corrofin WWTP discharges to the River Fergus, which is one of the main tributaries of the River Shannon, and is included in the catchment of the Shannon River Basin and in the EPA hydrometric and biological monitoring programs (Code 27F01). The river rises to the northwest of Corofin village upstream of Lough Inchiquin. The river is 59 kilometres long and has a catchment area of 1043 km2. The upper reaches of the catchment are primarily well draining agricultural lands. This area of the catchment includes several interconnected lakes and streams, which also drain parts of the Burren region. Karst features and underground drainage also affect Fergus river flows. There are no downstream abstractions of water for potable supplies or for agricultural purposes. The nearest abstraction point being located at Ballycullinaun Lough, which drains into the River Fergus downstream of Corrofin.

The Corrofin WWTP site is adjacent but surrounded on three sides by a designated Special Area of Conservation (Code: 001926), however the outfall will discharge to the River Fergus within the cSAC. In the ecological report by Dr. Dunford submitted, no rare plants were recorded during

Outfall point

site inspections. No plants listed on Annex II of Council Directive 92/43/EEC are listed for the East Burren Complex SAC (Code: 001926) and none of the habitats present were Annex I habitat types. Four Annex I bird species are listed, while two Annex II mammals are listed for this SAC. The wetlands adjacent to the WWTP site are important for the wintering of wildfowl. Mitigation measures for terrestrial elements of the construction works for the Corrofin WWTP include provision of an ornithologist to advise on best practice during construction works and the undertaking of major earthworks outside of the nesting season for wintering wildfowl. The main channel of the River Fergus is designated “salmonid” water, under the European Communities (Quality of Salmonid Waters) Regulations, S.I. 293 of 1988. Clare County Council undertake monitoring of the river at all the main bridges, along the length of the main river channel. Monitoring data for Riverstown Bridge, Corrofin Bridge and Addroan Bridge (in accordance with the parameters listed in the European Communities (Quality of Salmonid Waters) Regulations, S.I. 293 of 1988) is provided

in Attachment A-10. No breaches in limit values as set out in these Regulations have been identified over the most recent 27 monthly sampling events at Riverstown Bridge, Corrofin Bridge and Addroan Bridge. 8.3 Assimilative capacity of receiving waters The existing Corrofin WWTP is overloaded and in poor state of repair, however provision of a new WWTP providing for increased capacity from new developments in the Corrofin agglomeration is in place and construction should commence in 2009. Calculations for the assimilative capacity of the receiving waters is based on the discharge loads form the proposed WWTP. The Office of Public Works has collated flow data for the Fergus River. The 50%ile flow, dry weather flow (DWF) and 95%ile flow values, as set out in Table 3, are used to assess the assimilative capacity of the Fergus river for the discharge from the treatment plant. The full assimilative capacity calculation is provided in Attachment A-8 to this application. Table 3 Flow statistics for Fergus River Area Dry weather flow (EPA

hydrometric data) 95%ile flow (EPA data)

50%ile flow (EPA data)

Fergus river 0.1m3/sec 0.2m3/sec 1.46m3/sec Discharges from the Corrofin agglomeration contribute flow volumes to the Fergus River. The proposed total volume of discharge is 804m3/day, which approximates to 0.0093m3/sec. This flow is added to the base flow of the river to complete the assimilative capacity calculation for the discharge from the Corrofin WWTP. Consideration of the proposed total effluent discharge volume and associated nutrient loads are used to assess the likely impact of the discharge from the Corrofin WWTP on the water quality in the River Fergus and indicate that the receiving waters have adequate capacity to assimilate the nutrient loads for all parameters, with the exception of phosphate. The median concentration of molybdate reactive phosphate (MRP) at Corrofin Bridge (upstream of the discharge), measured over the April 2007-March 2009 period indicates a value of 0.0195mg/litre. MRP levels in the waters at Corrofin Bridge are likely to be associated with the discharge from the existing stormoverflow, located to the west of Corrofin Bridge. This storm overflow facility will be decommissioned once the new WWTP is constructed. A minimum requirement of the Local Government (Water Pollution) Act, 1977 (Water Quality Standards for Phosphorus Regulations) S.I. 258 of 1998 is that the waters would achieve a median MRP value of 0.03mg/litre to provide protection of conservation objectives and habitats in surface waters. While it is acknowledged that the existing WWTP in Corrofin is overloaded, construction of the new WWTP will commence in 2009 and the proposals include provision of phosphate reduction technology to reduce the level of phosphate in the discharge from the facility to a minimum of 2mg/l, and consequently to reduce phosphate levels in the receiving waters. This discharge arrangement will provide significantly greater assimilative capacity for the treated effluent. Further comment will be made on the results associated with the monitoring over the past 27 months, under Section 8.5 hereunder.

8.4 Total maximum nutrient load discharging to the River Fergus Analytical data for the wastewater discharge from the Corrofin WWTP is available of the effluent streams over several years. The influent and effluent streams are monitored for biochemical oxygen demand (BOD), chemical oxygen demand (COD), and suspended solids (SS). Results for 2007 and 2008 are used for this application. Flow data is not available for the influent load to the Corrofin WWTP. The discharge of the treated waste stream is used to assess the impact of the discharge on the receiving waters for biochemical oxygen demand (BOD) chemical oxygen demand (COD) and suspended solids (SS) to waters. The nutrient discharge load is synopsised in Table 4, based on the estimated average flow readings and mean analytical values for the dates presented. The average of the approximate hydraulic loadings as outlined in 6 above, is used to estimate the typical discharge load from the facility.

The Fergus River drains into Attedaun Lough approximately 500 metres downstream of the outfall point, however the nearest downstream river monitoring point is at Addroan Bridge, some 9 kilometres downstream. Summary results of monitoring at Riverstown Bridge and Corrofin Bridge (upstream of the WWTP discharge) and at Addroan Bridge (downstream of the WWTP discharge) for the past 27 sampling events are provided in Attachment A-10. The results indicate compliance with the standard limits set out in the above Regulations. However if the proposed environmental objectives for surface water are applied, (as set out in the Draft European Communities Environmental Objectives (Surface Waters) Regulations, 2008), then the results indicate compliance for the parameters BOD, MRP-P and NH3-N in the receiving waters with the exception of BOD, which is slightly above the requirements at Addroan Bridge (downstream of the WWTP discharge). Due to the distance downstream of Addroan Bridge, the impact of the Corrofin WWTP contributing to the elevated BOD levels is questionable. The median MRP values for waters in the Phosphorus Regulations are correlated with biological quality ratings, or Q values. The results also show compliance with Q4-5

(Class A) or good water quality with the standard defined for molybdate reactive phosphate (MRP) under the Local Government (Water Pollution) Act, 1977 (Water Quality Standards for Phosphorus Regulations) S.I. 258 of 1998. The median MRP concentration for the Addroan Bridge, downstream of the outfall from the Corrofin WWTP is 0.013mg/litre. Biological quality monitoring (Q rating) in accordance with the Local Government (Water Pollution) Act 1977 Water Quality Standards for Phosphorous Regulations, 1998 is undertaken on a national basis by the E.P.A. Clare County Council also commission Conservation Services to undertake biological monitoring of surface waters. The most recent Q-values recorded in 2007, Q3-4, have not changed from the previous monitoring in 2006 for the sites Corrofin Bridge (Site No. 0300), Ballyteigue Bridge (Site No. 0350) and Addroan Bridge (Site No. 0400). Monitoring data for Lough Atedaun, immediately downstream of Corrofin WWTP, is available for the year 2000 - Lakes of County Clare Report 2000-2001, by TCD November 2001. The results indicate that Lough Atedaun is classified as Mesotrophic status based on maximum Chlorophyll a levels, however if the classification is based on Total Phosphorus (TP) levels in the lake then it is classified as Eutrophic (average TP levels based on four samples only). The overall interim water quality status for the River Fergus downstream of Lough Inchiquin to Ennis is classified by the EPA as Poor status. Clare County Council, during the course of preparing the application for a discharge authorisation, under the Wastewater Discharge (Authorisation) Regulations 2007, (S.I No 684 of 2007) for the Corrofin WWTP, to the EPA assessed the Corrofin agglomeration to identify any facility liable to generate substances listed in Annex X of the Water Framework Directive (2000/60/EC) or relevant pollutants listed in Annex VIII of the Water Framework Directive. Monitoring for these substances was undertaken in April 2009 and results on this monitoring do not indicate any substance on the list was present in the waters of the Fergus or in the discharges to the river from the Corrofin WWTP (see Attachment F.1). No potential source of these pollutants has been identified in the sewer catchment, so it is unlikely that the discharge will contain the listed substances. Results from the survey will be collated and included in the licence application data as soon as may be on receipt of the results of the sampling exercise. The monitoring programs described above provide a good overview of the water quality status in the River Fergus, both upstream and downstream of the WWTP discharge. In conclusion, there is no indication of significant deterioration in quality status of the Fergus River downstream of the discharge from the treatment plant. 8.6 Impact of storm overflows A storm overflow is located at Corrofin Bridge. In preparation of a preliminary report by P H Mc Carthy & Partners, it was observed that the existing sewers were in poor condition with low capacities and shallow gradients in some areas leading to surcharging from time to time and the potential for overflow from the system. Any such overflow discharges to the River Fergus to the west of Corrofin Bridge. Sampling of the river was undertaken on April 14th 2009, during the course of preparing the licence application. Results from the survey will be collated and included in the licence application data as soon as may be on receipt of the results of the sampling exercise. The proposals to construct a new WWTP to serve the Corrofin agglomeration includes the decommissioning of this overflow discharge point.

9. Proposed technology for improving emissions from WWTP The existing Corrofin WWTP serves a population equivalent of 550, and is overloaded and in poor state of repair. In accordance with Clare County Council’s Water Services Investment Programme 2007-2009, Ballyvaughan, Doolin & Corofin are a bundled scheme with a projected cost of €18,025,000. Following approval of a Brief by the Department of the Environment Heritage and Local Government, and compliance with procurement processes, P H Mc Carthy & Partners were appointed to prepare a preliminary report. PJ Tobin & Co, Consulting Engineers were appointed as Consulting Engineers on 30th December 2002 for the project. Lands adjacent to the existing WWTP have been acquired for the proposed new wastewater treatment plant. The project commenced in 2008 and the network is near completion. The contract for the new wastewater treatment plant has been signed and the contractors are due to submit a final design before construction works commences in 2009. Due to the condition of the existing wastewater treatment facilities, the proposed treatment works will not incorporate the existing treatment units. In the Preliminary Report carried out by PH McCarthy & Partners in November 2000, the population for Corrofin being served by the WWTP was estimated as 492during the winter reaching a maximum of 878 in the summer period. The design population for the proposed Corrofin WWTP is 1725 PE, which takes into account a 20 year design horizon. Provision is in place for expansion should the population demand an increase. An indicative site layout plan is provided in Attachment A.7. 10. Measures planned to monitor emissions into the environment Provisions for monitoring emissions from the wastewater treatment plant are in place at the Corrofin WWTP. A full time laboratory technician is employed to cater for the operational requirements in terms of monitoring at the Corrofin treatment plant. Monitoring of influent and effluent wastewater streams is undertaken six times per annum for the parameters biochemical oxygen demand (BOD), chemical oxygen demand (COD) and suspended solids (SS). Methods of analysis and sampling procedures are provided in Attachment E.2 of this application. Sampling is currently undertaken as grab sample for both the influent and effluent streams. ________________________________________________________________

The Ballyvaughan, Corofin and Doolin Sewerage Schemes

LA03-33

G. Dollard, Planning DepartmentL. Conneally, Planning Department

This application is being made under the Part VIII procedure in accordance with thePlanning & Development Regulations, 2001.

1. Nature and extent of the proposed development and the principle featuresthereof.

It is proposed to upgrade the existing wastewater treatment works for the villageof Ballyvaughan. The existing sewer network in Ballyvaughan consists ofpartially separate foul and storm water collection systems. The foul sewersconvey wastewater to a collection point near the main pier from where it isdischarged untreated to thc foreshore and watercourses. The BallyvaughanSewerage Scheme will comprisc the construction of a new pumping station and anew wastewater treatment works in Lisnanard, west of Ballyvaughan village. Itis designed for a population equivalent (PE) of 2840 based on the predicted 20year summer flow (=peak flows). Effluent from the treatment works willdischarge to the sea in Galway Bay Complex candidate Special Area ofConservation (cSAC)/proposed Natural Heritage Area (pNHA) site code no.000268 via a 425m outfall pipe. The outfall route will pass through part of thecSAC to the nOlih of the Ballyvaughan-Fanore road, and from there into the sea.At Ballyvaughan, the treatment works site comprises a mix of improvedgrassland and dense blackthorn-hawthorn-hazel scrub (see photos).

It is proposed to construct a waste water treatment works at Doonmacfellim,Doolin. At present there is no foul collection system in the village of Doolin andproperties are served by proprietary treatment systems and septic tanks. Theproposal will result in the removal of existing septic tanks and private wastewater treatment systems in a substantial area which will have environmentalbenefits to this location. It is proposed that a treated effluent outfall will gravitatetreated effluent flows north to the cliff on the Atlantic Ocean. The DoolinSewerage Scheme will comprise the construction of four new pumping stations(in Terrgoncan, Doolin, Doonagore and Ballaghlinc) and a new wastewatertreatment works in Doonmacfelim 'I'd. It is designed for a PE of 2089 based onthe predicted 20 year summer flow. The site of the proposed treatment works isnot covered by any conservation designation and is characterised by improvedgrassland and low lying dry stone boundary walls. A section of the outfall routefrom the treatment works is through an area of limestone pavement, an Annex Ipriority habitat, in Black Head-Poulsallagh Complex candidate Special Area ofConservation (cSAC)/proposed Natural Heritage Area (pNHA) site code no.000020. Effluent will discharge from a cliff to the marine area within the cSAC.

The Corofin Sewerage Scheme will comprise the construction of two newpumping stations and a new wastewater treatment works in BallykinnacoraNorth, on the eastern side of Corofin. The existing sewer network in the villageconsists of partially separatc foul and storm waste collection systems. Theexisitng works is old, heavily overloaded and in poor condition. It is designed fora PE of 3465 based on the predicted 20 year summer flow. The site of theproposed treatment works is beside the River Fergus in an area marked as 'liableto floods' on the six-inch OS map of the area. It is outside but surrounded onthree sides by East Burren Complex candidate Special Area of Conservation(cSAC)/proposed Natural Heritage Area (pNHA) site code no. 001926. Effluentfrom the treatmcnt works will discharge to the River Fergus within the cSAC.The treatment works site at Corofin is part of the floodplain of the River Fergus,and supports a mix of wet grassland of some ecological value, and improvedgrassland.

2. Evaluation of the likely implications, if any, of the proposed developmentwith respect to the proper planning and development of the area in which thedevelopment would be situated.

It is important to note that the layouts a/the three proposed Wastewatertreatment works are indicative only. The three works are to be procured using aDBO contract, the design will be undertaken by the succes!>jul contractor and theexact layout ofeach works will be decided at that time. The DBO contractdocuments will specifj) particular requirements or details which will be outlinedby way a/condition at the end o/this report.

Corofin:

The perceived impacts in planning terms with the proposed Corofin upgrade areoutlined below. lt must be stated at the outset that the proposal will improve thecurrent situation with regards the public sewerage system servicing this area.

I. The treatment works site at Corofin is located on the River Fergus floodplain, inan area that is wet and considered likely to flood. A lack of information isprovided on the maximum flood levels on the site. Maximum flood levels mustbe established in order to offset the impact of the development on the flood plain.To offset the degree of run off from the hard surfaced area and the consequentimpact of the functioning of the floodplain, consideration should be given to theuse of permeable surface material within the affected area. A full flood impactassessment should therefore be submitted. Levels must be taken into account indesigning the facility. lt is considered that this issue can be addressed by way of apre-development condition.

2. As there are areas of wet grassland of some ecological value in the site, attemptsshould be made to avoid these areas. Currently the development is located in theeastern end of the site and this is the wettest end that supports the main areas ofwet grassland. Dr Dunford (in the ecological report submitted with theapplication) describes the area as 'part ofa very important wetland complex usedby wintering bird~', and the impacts on birds as a result of the loss of some of thisarea should be considered.

3. The new treatment works at Corofin will discharge to the River Fergus within thecSAC. The level of treatment of the effluent appears to be secondary only.Proposed effluent treatment standards are: BOD, 25mg/l; COD, 125mg/l; Totalsuspended solids 35mg/l; Ammoniacal Nitrogen, 5mg/l; Total Phosphorous,2mg/l.

4. A report on the ecology of the River Fergus was prepared by Aqua-Fact. Theriver had biological quality ratings of Q3 and Q2-3 above and below the currentdischarge point, respectively, indicating moderately polluted water at all threesampling stations in 2003. In terms of chemical analysis, a single water samplewas taken from a point downstream of the current discharge point (samplingstation 1). Results for total phosphate, nitrate, nitrite and ammonium arepresented, and levels of total Phosphorus and total Nitrogen are currently belowthe limits set in the Urban Wastewater Directive. There is no information on thechemieal composition of water above the discharge point at present so comparisonis not possible. It is therefore considered that ehemieal analysis of the waterabove the current discharge point be undertaken prior to and during operation ofthe plant to ensure good baseline information on water quality in the river. Thisshould allow for changes and improvements in water quality to be monitored inthe future.

5. Mitigation measures for the terrestrial elements of the proposed works arerecommended in Dr Dunford's ecological report. Thesc include limiting theworks areas, partieularly along the outfall routes, to avoid stone walls and other

features of ecological value. Working outside sensitive periods for wildlife (e.g.breeding season for birds and other animals, the winter in areas that are importantfor wintering birds) is recommended. It is also recommended that an ecologist bein attendance to oversee operations at all three sites during construction. It isconsidered that these mitigation measures are reasonable and should be includedas conditions at time of decision. In the case of Corofin the 2nd pumping station islocated in close proximity to Corofin Bridge which is a protected structure (PSNo.197). The setting of this bridge and views to and from are important. It isconsidered that P.S no.2 will have a significant negative visual impact on thisprotected structure and so its relocation away from the bridge is advised. Providedthe line of vision afforded from the Ennis Road to the Bridge is maintained apumping station in this immediate area is otherwise considered acceptable.

Ballyvaughan:

The perceived impacts in planning terms with the proposed Corofin upgrade areoutlined below. It must be stated at the outset that the proposal will improve thecurrent situation with regards the public sewerage system servicing this area.

I. The impact of the development on trees and shrubs along the entrance shouldbe assessed and proposals provided to offset any unnecessary damage orremoval. The area is characterised by heavy vegetation which needs to bemaintained to retain the rural coastal feel of the site.

2. The findings at the site in relation to birds and mammals with regard to thepotential impact of this development are unclear. A complete methodstatement with respect to this and the above will need to be submitted.

3. The transect undertaken for the intertidal survey along the route of theproposed sewage pipe (Figure 1, Appendix D) does not appear to coincidewith the route of the proposed pipe as described in Appendix B (Figure 11).Accordingly, clarification of the outfall location and depth at chart datum isrequired.

4. Any use of explosives in the marine environment during the constructionphase should be monitored and a schedule of works agreed prior tocommencement.

5. Emergency overflow arrangements that result in raw sewage discharge to acSAC are an unsatisfactory arrangement. It is considered that the proposedholding tank be increased in volume to satisfactorily cater for such overflow intimes of emergency.

Doolin:

It is considered that the proposed Doolin waste water treatment plant posed themost problematic development of the 3 no. plants. The coastal location and thevisual impacts as well as the potential impacts on the cSAC (limestone pavement)and the discharge to the sea are a cause of concern to the Planning Authority.

However, following detailed assessment of the impacts and examination of therelevant reports, it is considered that the development will result in the removal ofcxisting septic tanks and private waste water treatment systems in a substantialarea which will have environmental benefits to this coastal location. Conditionsare proposed to be attached to control the impacts of the development. Theperceived impacts in planning terms with the proposed Doolin WWS are outlinedbelow.

I. Where the outfall route passes through the cSAC at Doolin, there arerecommendations to take every available measure to minimise impacts on theareas of limestone pavement in the cSAC, and to implement best practice. Thereis also a suggestion that the outfall pipe be routed overground, with appropriatelandscaping, to avoid the need for excavation in the cSAC. It is considered thatthis proposal would lead to a substantial visual impact in the landscape and so isnot recommended. As stated by Dr. Dunford in his report "in defence of the routeproposed, it should be noted that very similar habitats to those affected arecommonly available adjacent to the site. Thus, the existing geological andecological features arc well represented locally, and faunal communities impactedby the works have access to ample alternative habitats." Little information isprovided however on how the pipe will be laid. It is also unclear what works areproposed at the cliff and no indication is given of how the discharge pipe will belaid.

2. While it is acknowledged that "the construction of the sewage treatment facilityand laying of the pipeline at Doolin, Co. Clare within the SA C complex (BlackHead/Poulsallagh Complex cSAC), will result in the loss ofmarine and terrestrialhabitat(appendix L Pg7) ", it must be noted that under existing conditions alldomestic sewage in the Doolin area is treated by individual tanks which leftunchecked will have considerable impacts on the wider area (ground water etc)and limit the development potential of the settlement.

3. There seems to be some lack of clarity as to the outfall location. Drawing #116/011066 indicates an outfall at cliffs approximately 9.5 m above ground level.Yet the ecological survey in Appendix L makes reference to "the subtidal route ofthe pipeline". It is important that this be clarified so that the proposed route isfully understood.

4. It is considered that ofl'the three treatment works the scheme in Doolin representsthe more potentially visually intrusive development given the detached nature ofthe site within the exposcd and open coastal area of Doolin. As detailed indrawings ((Drg.116/01l070) efforts have been made to utilise the existingcontours of the site and recess the building mass into the landscape. Natural localstone is to front the development which will help integrate the building further.While indicative the development should respect this approach.

5. alI the three schemes Doolin utilises the greatest number of pumping stations. Itis important that materials used to screen the development are sensitive to thelandscape and character of the area.

1) The lack of tertiary trcatment in the Ballyvaughan plant given that the outfall willaffect a designated cSAC and shellfish area;

g) Thc use of overflow tanks to deposit untreated efffluent to open watercourses intimes of emergency is unsatisfactory and another means of storage-treatment isrecommended;

6. Response of the Local Authority thereto.

a) pump station no.2 is to be relocated by condition to ensure views of the Bridgeare ensured

b) the new locations have been provided by way of revised layouts and areconsidered acceptable

c) The use of palisade fencing to demarcate treatment works sites is seen asinappropriate to these areas and more sympathetic materials and boundarytreatments should be utilised

d) Control buildings will be conditioned such that natural materials are usedthroughout and follow the rural design vernacular suitable to the recipientarea. Pitched roofs should be observed with a ridge height not exceeding 6.0m.

e) Monitoring of ecological/ornithological and archaeological activity will beensured by way of condition

1) UV sterilistion shall be conditioned on treated effluentg) Conditions will be attachcd to oversize all tanks to eliminate emergencyoverflow pipes to open watercourses and special areas of conservation

7. The manner in which the development is proposed to proceed

Having regard to the detail of the reports and the various assessments /considerations / objections of the various elements of the development, it isconsidered that the developments, subject to conditions, will represent the bestenvironmental solution and will be in the interests of the proper planning anddevelopment ofthe affected areas, Ballyvaughan, Corofin and Doolin inaccordance with the policies of The County Development Plan, 1999 as varied.

As such, it is recommended that planning permission be granted for the 3 no.projects subject to the following conditions being be attached for inclusion in thetender documentation:

1. General conditions:

y No decision shall be made on the final selection of the treatment plants

(design, layout and pipe route and outfall) following the tendering process

without the agreement of the Planning Authority. Full details of all tenders

shall be submitted for consideration and the final selection of all treatment

works shall be agreed.

Population Agglomeration: Flow data for the WWTP is not available. The design population for the existing Corrofin WWTP is 550 PE, however the treatment plant is overloaded and in poor state of repair. The contract for the new wastewater treatment plant has been signed and the contractors are due to submit a final design before construction works commences in 2009. In the Preliminary Report carried out by PH McCarthy & Partners in November 2000, the population for Corrofin being served by the WWTP was estimated as 492 during the winter reaching a maximum of 878 in the summer period. The design population for the proposed Corrofin WWTP is 1725 PE, which takes into account a 20 year design horizon. This equates to an approximate hydraulic loading arriving at the Corrofin WWTP of 111m3/day (winter) and 197m3/day (summer). These measurements were used to estimate the final population equivalent, based on the average influent BOD values between May 2007 and March 2009, - 264 mgO2/litre BOD. The population equivalent for this loading is 488 PE (winter) and 866 PE (summer). This approach to estimation of population equivalent is in accordance with the definition provided in the Waste Water Discharge (Authorisation) Regulations, 2007 (“population equivalent” is a measurement of organic biodegradable load and a population equivalent of 1 (1 p.e.) means the organic biodegradable load having a five-day biochemical oxygen demand (BOD5) of 60g of oxygen per day; the load being calculated on the basis of the maximum average weekly load entering the waste water works during the year, excluding unusual situations such as those due to heavy rain).

The Wastewater Treatment Plant (WWTP) The existing Corrofin WWTP, which was constructed in the 1950’s, is located to the east of the village along the southern banks of the River Fergus. The treatment works site is part of the floodplain of the River Fergus and supports a mix of wet grassland of some ecological value and improved grassland. The design population for the existing Corrofin WWTP is 550 PE, however the treatment plant is overloaded and in poor state of repair. In accordance with Clare County Council’s Water Services Investment Programme 2007-2009, Ballyvaughan, Doolin & Corofin are a bundled scheme with a projected cost of €18,025,000. Following approval of a Brief by the Department of the Environment Heritage and Local Government, and compliance with procurement processes, P H Mc Carthy & Partners were appointed to prepare a preliminary report. PJ Tobin & Co, Consulting Engineers, were appointed as Consulting Engineers on 30th December 2002 for the project. Land adjacent to the existing WWTP has been acquired for the proposed new wastewater treatment plant. The project commenced in 2008 and the network is near completion. The contract for the new wastewater treatment plant has been signed and the contractors are due to submit a final design before construction works commences in 2009. Due to the condition of the existing wastewater treatment facilities, the proposed treatment works will not incorporate the existing treatment units. In the Preliminary Report carried out by PH McCarthy & Partners in November 2000, the population for Corrofin being served by the WWTP was estimated as 492during the winter reaching a maximum of 878 in the summer period. The design population for the proposed Corrofin WWTP is 1725 PE, which takes into account a 20 year design horizon. Provision is in place for expansion should the population demand an increase. Table 1: Design data for proposed Corrofin WWTP Design Load 1725 PE DWF 804 m3/day BOD5 Load 103.5 kg/day DWF taken from Preliminary Report by PH McCarthy & Partners in November 2000 The above design was based on previous definitions of population equivalent and dry weather flow, with 60grms BOD5 and 225 litres flow per head per day. Under the Waste Water Discharge (Authorisation) Regulations, 2007, the calculation of population equivalent is based on the maximum average weekly flow entering the wastewater works during the year and measurement of organic biodegradable load for this flow, allowing 60g of BOD5 per head of population. Treatment Process Description Corrofin WWTP consists of the following elements:

Inlet screening, fitted with screening removal and bypass Imhoff tank Sludge Drying Beds

Clare Co.Co. Environmental Laboratory Author:MMcN Test Methods Manual Issued By: MMcN pH Issue Date: 31/03/09 Method No. 1 Issue No: 1 Page 1 of 3 1. METHOD PRINCIPLE The pH is the negative logarithm of the hydrogen ion concentration of a solution and is thus a measure of whither the liquid is acid or alkaline. The basic principle of electrometric pH measurement is the determination of the activity of the hydrogen ions by potentiometric measurement using a standard hydrogen electrode and a reference electrode. 2. SAMPLING AND SAMPLE PRESERVATION Samples should be taken in accordance with the procedures set out in the Laboratory Sampling Manual. Analyse samples within 2 hours after receiving to the lab. 3. SAFETY PRECAUTIONS Good safety habits and laboratory techniques should be used throughout the procedure; these are outlined in the Laboratory Safety Manual. Consult the Material Safety Data Sheets for information specific to the reagents used.

4. INTERFERENCES Greasy or oily samples may cause blockage of the electrode. 5. REAGENTS

Clare Co.Co. Environmental Laboratory Author: M.McN Test Method Manual Issued By: MMcN Chemical Oxygen Demand. High Range ( 20-1500 mg/L O2)

Low Range (10- 150 mg/l O2)

Issue Date: 17/02/09

Method No. 2 Issue No:1 Page 1of 4 1. METHOD PRINCIPLE The mg/L COD results are defined as the mg of O2 consumed per litre of sample under conditions of this procedure. In this procedure the sample is heated for 2hrs with a strong oxidising reagent, potassium dichromate. Oxidisable organic compounds react, reducing the dichromate ion to green chromic ion ( Cr3+). When the 10-150 mg/L method is used the amount of CR6+ remaining is determined. When the 20-1500 mg/L is used the amount of Cr3+ produced is determined. The COD reagent also contains silver and mercury ions. Silver is a catalyst and mercury is used to complex chloride interference’s.

2. SAMPLING AND SAMPLE PRESERVATION Samples should be taken in accordance with the procedures set out in the Laboratory Sampling Manual. Analyse samples as soon as possible after receipt to the lab, otherwise refrigerate and analyse within 48 hours. If this cannot be achieved preserve samples by acidification to pH < 2 with H2SO4 (2mls per litre), refrigerate and analyse within 28 days. 3. SAFETY PRECAUTIONS Good safety habits and laboratory techniques should be used throughout the procedure; these are outlined in the Laboratory Safety Manual. Vials contain sulphuric acid (86%), potassium dichromate silver and mercury. Consult Material Safety Data Sheet for information specific to the reagents used. Wear appropriate skin and eye protection. Vials are heated to 1500C so vials and digestion rack is very hot, take suitable precautions. 4. WASTE DISPOSAL Final samples contain mercury, silver and chromium at concentrations which are hazardous so all COD vials must be disposed of by sending to Shannon Environmental Services. The used vials are stored in the used delivery containers marked “waste” pending collection. 5 INTERFERENCES Chloride is the primary interference when determining COD concentration. Each COD vial contains mercuric sulphate which will eliminate chloride interference up to 2000 mg/L in the sample, if the sample contains greater than this it must be diluted.

Clare Co.Council Environmental Laboratory Author:MMcN Test Method Manual Issued By: MMcN 5 day Biochemical Oxygen Demand Test Issue Date: 17/02/09 Method No. 3 Issue No: 1 Page 1 of 6 1. METHOD PRINCIPLE The method consists of filling with diluted and seeded sample, to overflowing , an airtight bottle of specified size and incubating it at 200C for 5 days. Dissolved oxygen is measured initially and after incubation and the BOD is computed from the difference between initial and final DO. A factor which must be borne in mind in obtaining and assessing B.O.D. results is nitrification. This is the oxidation of ammonia to nitrate by nitrifying bacteria and if the process is occurring under test conditions high oxygen uptake values will be recorded. For normal river waters the onset of nitrification conditions does not occur within the 5 day period but in the case of wastewaters containing nitrifying organisms this phenomenon will take place much more promptly and unless nitrification is inhibited the result is an apparently very high B.O.D. level. 2. SAMPLING AND SAMPLE PRESERVATION

Samples should be taken in accordance with the procedures set out in the Laboratory Sampling Manual. If analysis is begun within 2 hrs of collection cold storage is unnecessary if not, keep sample refrigerated before analysis. Analyse sample within 24h of collection. Warm chilled samples to 20oC + 30C . 3. SAFETY PRECAUTIONS Good safety habits and laboratory techniques should be used throughout the procedure; these are outlined in the Laboratory Safety Manual. 4. INTERFERENCES Samples containing caustic alkalinity or acidity must be neutralised to pH 6.5 to 7.5 with a solution of Sulphuric acid or Sodium hydroxide to pH 6.5 to 7.5 of such strength that the that the quantity of reagent does not dilute the sample by more than 0.5%. 5. REAGENTS • B.O.D. nutrient powder pillows ( Hach Prod.Code:14861-98) • Quality Control Solution : Glucose Glutamic Acid Standard Soln • Allythiourea (BDH analar,104622A) • TCMP ? • Seed ( diluted mixed liquor)

APPARATUS • Incubator @ 20 0C + 10C • Incubation bottles, 250 to 300 mls capacity • Water bath , thermostatically controlled at 200C + 10C • Dissolved Oxygen Meter 7. PROCEDURE (A) Preparation of Quality Control solution: • Dry Glucose (BDH, Analar grade 10117Y) and reagent grade Glutamic acid (BDH

Biochemical 371064E) at 1030C for 1 hr. Allow to cool in a dessicator. • Dissolve 0.15g Glucose and 0.15g Glutamic acid distilled water and dilute to 1litre in a

volumetric flask. Mix well. Prepare fresh immediately before use. Store all Glucose/Glutamic mixtures at 40 C or lower. Record in the QC log book and assign a QC number

(B) Preparation of Reagents. • Source Water for Sample Dilution : A quantity of distilled water is aerated overnight, on the

day of the test 1 BOD nutrient powder pillow is added to 3 litres water. • Allylthiourea (Nitrification Inhibitor): This is used if analysing samples that require

nitrification inhibition e.g. Wastewater Treatment Plant samples. Dissolve 0.2g of Allythiourea (BDH analar,104622A) in 150 mls purified water and make up to 200mls in a volumetric flask. This solution is stable for up to two weeks if kept refrigerated. Record preparation in the back QC logbook.

• SEED (C) Preparation of Blanks, Samples & Quality Control: Samples both diluted and undiluted , dilution water blanks and Quality Control Samples should be treated in the same way. All samples must be brought to 200C + 30 C before D.O. measurement. Preparation of Dilution Water Quality Check Blanks:

• Two blanks must be run with each set of analysis, which contain nutrient, mineral and buffer solution but no seed or nitrification inhibitor , this serves as a check on quality of unseeded dilution water and cleanliness of incubation bottles. The DO uptake should should not exceed 0.2mg/L.

• for blank determination the prepared dilution water is treated as a sample. Place prepared dilution water into pre - labeled BOD bottles. Fill the BOD bottle to overflowing with sample. Remove any entrapped air bubbles by gently tapping the bottle.

• If using a nitrification inhibitor, add 1ml of Allythioura solution per 500 mls sample, two ATU blanks must be prepared and treated in the same way as the samples.

• Place the BOD bottles in the water-bath until ready for D.O. measurement.

Clare Co. Council Environmental Laboratory Method No.3 Page 3 of 6 BOD Test Issue No. 1 Issue Date 17/02/09 Preparation of Quality Control Samples:

• At least two QC samples must be run with each set of analysis, this is prepared by diluting the Glucose/Glutamic Standard solution by 50 with the dilution water in a volumetric flask or graduated cylinder. Place prepared QC sample into pre - labeled BOD bottles. Fill the BOD bottle to overflowing with sample. Remove any entrapped air bubbles by gently tapping the bottle.

• If using a nitrification inhibitor, add 1ml of Allythioura solution per 500 mls QC sample. • Place the BOD Bottle in the water- bath until ready for D.O. measurement.

Preparation of Samples:

• Some samples may require dilution , if the BOD is expected to be greater than 7mg/l O2 then the sample requires dilution . Make at least two dilutions of prepared sample estimated to produce a residual DO of at least 1.0 mg/L and a DO uptake of at least 2.0 mg/L.(Use dilution chart in Appendix 1 as reference).

• Prepare dilution by adding desired amount of sample to a 500 mls Class A Graduated Cylinder ( For dilution greater than 1:100 make a primary dilution first.

• Add X mls of seed and (nitrification inhibitor) solution per 500 mls diluted sample • Label BOD bottles with No. of sample, dilution and date. Shake vigorously and pour into BOD bottle (this is to ensure that sample is saturated with oxygen). • Fill the BOD bottle to overflowing with sample. Remove any entrapped air bubbles by

gently tapping the bottle. • Samples must be brought to 200C in a water-bath before DO measurement, after preparing

dilution measure initial DO within 30 min. (D) Calibration of Dissolved Oxygen Meter. NEW SECTION (E) Measurement of DO in Samples /Blanks and Quality Control Sample • Insert the funnel and stirrer into the BOD bottle to be measured, insert the electrode into the

bottle. Ensure that there are no air bubbles trapped on the electrode head. Allow the DO reading to stabilise, the sample when fully saturated at 200C should read between 8.8 to 9.2 mg/l. Record the DO1 for the blanks, QC and samples on the worksheet. Rinse the probe between sample measurement.

• Put the glass top on the bottle, ensure that no air bubbles are trapped. Seal with parafilm to prevent evaporation. Place the BOD bottle in the incubator for 5 days.

• After 5 days remove the BOD bottle from the incubator and record the DO5 remaining on the worksheet.

• Record samples with inhibition and without inhibition of separate worksheets. Samples with inhibitor added must be recorded as CBOD (Wastewater Treatment Plant Samples)

Clare Co. Council Environmental Laboratory Method No.3 Page 4 of 6 BOD Test Issue No. 1 Issue Date 17/02/09 8. CALCULATIONS: • The DO remaining in the bottle after 5 days should be greater than 2 mg/l and there should be a

DO depletion of at least 2mg/l to accept results. • If more than 1 sample dilution meets the above criteria average results in the acceptable range,

this applies to the QC samples, blanks and diluted samples. • The BOD of the blank should be < 1 mg/l O2, values of greater than this should be checked for

possible sources of contamination. Protect water quality by using clean glassware, tubing and bottles.

• The calculations are done using an excel worksheet (BOD calculation worksheet) as follows: 1. Always open the master worksheet blank to input data in the following filename/path:

T:\Environment/lab /lab/Excel Graphs Ammonia, BOD Calculations/BOD Calculations /Calculation Template.

2. Enter all sample values obtained for DO1 and DO5 and dilutions used. The calculations are automatically done. Remember not to accept results if there is < 2.0 mg/l O2 left in the bottle or if there is an uptake of < 2mg/l O2. The results that are not acceptable will be highlighted. Results, which are highlighted, must be excluded from the final average value.

3. Do not save onto this sheet. All data should be saved in Work in Progress file (WIP)/Year /Month of analysis/ and saved under test date and initials of analyst. Differentiate between the results for BOD & CBOD.

4. Always open the master sheet. Never modify a previously used data sheet. 5. Print the sheet and attach to the worksheet and place in results folder. Initial hand written raw

data and computer print out. 6. The calculation used in the excel sheet is as follows: Undiluted Samples: Diluted Samples: DO1 – DO5 = BOD mg/l O2

F X { ( DO1 – DO5)} – {(F-1)/F X ( B1 – B5)=BOD mg/L O2.

DO 1= Initial DO of sample DO5 = DO of sample after 5 days incubation

F = Dilution Factor, DO1 = Initial DO of diluted sample DO5 = DO of diluted sample after 5 days incubation BB1 = Initial DO of blank, B5 = DO of blank after 5 day incubation.

METHOD PRINCIPLE The procedure consists of filtering a well mixed sample through a weighed glass–fibre paper (grade GF/C with particle retention of 1.2um) and the residue on the filter is dried at 103 to 1050C. The increase in the weight of the filter represents the total suspended solids. 2. SAMPLING AND SAMPLE PRESERVATION Samples should be taken in accordance with the procedures set out in the Laboratory Sampling Manual. Samples must be refrigerated to minimize microbiological decomposition of solids and analyzed within 7 days.

3. SAFETY PRECAUTIONS Good safety habits and laboratory techniques should be used throughout the procedure; these are outlined in the Laboratory Safety Manual.

4. INTERFERENCES Exclude large floating particles if it is determined that their inclusion is not representative. For samples high in dissolved solids e.g. chloride, thoroughly wash the filter to ensure removal of the dissolved material. 5. REAGENTS Kaolin Quality Control Sample (200mg/L): Weigh 0.200g of Kaolin (Aldrich 22,883-4) dilute to 1litre in a volumetric flask with purified water. Mix well. Record in QC log book and assign number. 6. APPARATUS • 1 litre Buchner flask • GF/C Whatman filter papers (90mm) • Oven for operation at 103 to 105 oC • Analytical Balance • Dessicator

Clare Co. Council Environmental Laboratory Method No.4 Page 2 of 3 Total Suspended Solids. Issue No. 1 Issue Date 17/02/09 7. PROCEDURE (a) Preparation of GF/C Filter Papers • Insert numbered GF/C filter paper with wrinkled side up into filtration apparatus. • Apply vacuum and wash filter paper with 3 successive 20 mls portions of purified water.

Continue suction to remove all traces of water and discard washings. • Remove filter and dry in an oven at 103 to 1050C for 1 hour. • Cool in a dessicator to balance temperature and weigh, record of the worksheet. Store in

dessicator until needed. • A pre-weighed, numbered filter paper is required for each sample and QC sample.

(b) Sample Analysis • Prepare Quality Control Sample as above. At least one Quality Control sample must be run

with each batch of samples. Use 250mls of Quality Control sample per determination. • Place numbered pre-weighed filter paper on filter apparatus, wash with a small volume of

purified water to seat it. • Ensure sample is well mixed, pour a volume of the well-mixed sample onto the filter paper

(the volume chosen depends on the concentration of solids in the sample e.g. up to 500 mls can be filtered for samples of low suspended solids content and less than 100 mls samples are used if there is a high suspended solids content).

• Wash with three successive 10 ml volume of purified water and allow complete drainage between washings. Samples with high dissolved solids may require additional washings. Continue suction for about 5 minutes after filtration is complete.

• Record the volume filtered on the worksheet. • Carefully remove the filter from the apparatus place in the oven for 1 hour at 103 to 1050C. • Remove from oven, cool in dessicator and weigh, record final weight on worksheet and do

calculations below. Record value of QC sample on QC chart. 8. CALCULATIONS/RESULTS • The Total Suspended Solids is calculated as follows:

mg/L: Total Suspended Solids = ( A – B ) X 1,000,000 Sample Volume (ml)

A: Weight of filter plus dried residue (g) B: Weight of filter (g)

• Report results as mg/L SS to three significant figures.

(i) Description of receiving waters (ii) Statutory Designations of the Receiving Waters (iii) Assimilative capacity of the receiving waters (iv) Total maximum nutrient load discharging to receiving waters (v) Monitoring undertaken on receiving waters (vi) Impact of storm overflows

(i) Description of receiving waters The Corrofin WWTP discharges to the River Fergus, which is one of the main tributaries of the River Shannon, and is included in the catchment of the Shannon River Basin and in the EPA hydrometric and biological monitoring programs (Code 27F01). The river rises to the northwest of Corofin village upstream of Lough Inchiquin. The river is 59 kilometres long and has a catchment area of 1043 km2. The upper reaches of the catchment are primarily well draining agricultural lands. This area of the catchment includes several interconnected lakes and streams, which also drain parts of the Burren region. Karst features and underground drainage also affect Fergus river flows. There are no downstream abstractions of water for potable supplies or for agricultural purposes. The nearest abstraction point being located at Ballycullinaun Lough, which drains to the River Fergus downstream of Corrofin. The river water quality at Riverstown Bridge (Site No. 0200), Corrofin Bridge (Site No. 0300),Ballyteige Bridge (Site No.0350) and at Addroan Bridge (Site No. 0400), downstream of Lough Attedaun, Lough Keagh and Ballyteigye Lough are classified with a Q value of 3-4 in the most recent monitoring conducted in 2007 as outlined in Table 1 below. The overall interim water quality status for the Fergus River has been classified by the EPA as Poor water quality status, along the river length downstream of Lough Inchiquin to Ennis.

The Corrofin WWTP site is adjacent but surrounded on three sides by a designated Special Area of Conservation (Code: 001926), however the outfall will discharge to the River Fergus within the cSAC. In the ecological report by Dr. Dunford submitted, no rare plants were recorded during site inspections. No plants listed on Annex II of Council Directive 92/43/EEC are listed for the East Burren Complex SAC (Code: 001926) and none of the habitats present were Annex I habitat types. Four Annex I bird species are listed,

while two Annex II mammals are listed for this SAC. The wetlands adjacent to the WWTP site are important for the wintering of wildfowl. Mitigation measures for terrestrial elements of the construction works for the Corrofin WWTP include provision of an ornithologist to advise on best practice during construction works and the undertaking of major earthworks outside of the nesting season for wintering wildfowl. The main channel of the River Fergus is designated “salmonid” water, under the European Communities (Quality of Salmonid Waters) Regulations, S.I. 293 of 1988. Clare County Council undertake monitoring of the river at all the main bridges, along the length of the main river channel. Monitoring data for Riverstown Bridge, Corrofin Bridge and Addroan Bridge (in accordance with the parameters listed in the European Communities (Quality of Salmonid Waters) Regulations, S.I. 293 of 1988) is provided in Attachment A-10. No breaches in limit values as set out in these Regulations have been identified over the most recent 27 monthly sampling events at Riverstown Bridge, Corrofin Bridge and Addroan Bridge. (iii) Assimilative capacity of receiving waters The existing Corrofin WWTP is overloaded and in poor state of repair, however provision of a new WWTP providing for increased capacity from new developments in the Corrofin agglomeration is in place and construction should commence in 2009. Calculations for the assimilative capacity of the receiving waters is based on the discharge loads form the proposed WWTP. The Office of Public Works has collated flow data for the Fergus River. The 50%ile flow, dry weather flow (DWF) and 95%ile flow values, as set out in Table 2, are used to assess the assimilative capacity of the Fergus river for the discharge from the treatment plant. The full assimilative capacity calculation is provided in Attachment A-8 to this application. Table 2 Flow statistics for Fergus River Area Dry weather flow (EPA

hydrometric data) 95%ile flow (EPA data)

50%ile flow (EPA data)

Fergus river 0.1m3/sec 0.2m3/sec 1.46m3/sec Discharges from the Corrofin agglomeration contribute flow volumes to the Fergus River. The proposed total volume of discharge is 804m3/day, which approximates to 0.0093m3/sec. This flow is added to the base flow of the river to complete the assimilative capacity calculation for the discharge from the Corrofin WWTP. Consideration of the proposed total effluent discharge volume and associated nutrient loads are used to assess the likely impact of the discharge from the Corrofin WWTP on the water quality in the River Fergus and indicate that the receiving waters have adequate capacity to assimilate the nutrient loads for all parameters, with the exception of phosphate. The median concentration of molybdate reactive phosphate (MRP) at Corrofin Bridge (upstream of the discharge), measured over the April 2007-March 2009 period indicates a value of 0.0195mg/litre. MRP levels in the waters at Corrofin Bridge are likely to be associated with the discharge from the existing stormoverflow, located to the west of Corrofin Bridge. This storm overflow facility will be decommissioned once the new WWTP is constructed. A minimum requirement of the Local Government (Water Pollution) Act, 1977 (Water Quality Standards for Phosphorus Regulations) S.I. 258 of 1998 is that the waters would achieve a median MRP value of 0.03mg/litre to provide protection of

conservation objectives and habitats in surface waters. While it is acknowledged that the existing WWTP in Corrofin is overloaded, construction of the new WWTP will commence in 2009 and the proposals include provision of phosphate reduction technology to reduce the level of phosphate in the discharge from the facility to a minimum of 2mg/l, and consequently to reduce phosphate levels in the receiving waters. This discharge arrangement will provide significantly greater assimilative capacity for the treated effluent. Further comment will be made on the results associated with the monitoring over the past 27 months, under Section 8.5 hereunder. (iv) Total maximum nutrient load discharging to the River Fergus Analytical data for the wastewater discharge from the Corrofin WWTP is available of the effluent streams over several years. The influent and effluent streams are monitored for biochemical oxygen demand (BOD), chemical oxygen demand (COD), and suspended solids (SS). Results for 2007 and 2008 are used for this application. Flow data is not available for the influent load to the Corrofin WWTP. The discharge of the treated waste stream is used to assess the impact of the discharge on the receiving waters for biochemical oxygen demand (BOD) chemical oxygen demand (COD) and suspended solids (SS) to waters. The nutrient discharge load is synopsised in Table 3, based on the estimated average flow readings and mean analytical values for the dates presented. The average of the approximate hydraulic loadings as outlined in 6 above, is used to estimate the typical discharge load from the facility.

The Fergus River drains into Attedaun Lough approximately 500 metres downstream of the outfall point, however the nearest downstream river monitoring point is at Addroan Bridge, some 9 kilometres downstream. Summary results of monitoring at Riverstown Bridge and Corrofin Bridge (upstream of the WWTP discharge) and at Addroan Bridge (downstream of the WWTP discharge) for the past 27 sampling events are provided in Attachment A-10. The results indicate compliance with the standard limits set out in the above Regulations. However if the proposed environmental objectives for surface

water are applied, (as set out in the Draft European Communities Environmental Objectives (Surface Waters) Regulations, 2008), then the results indicate compliance for the parameters BOD, MRP-P and NH3-N in the receiving waters with the exception of BOD, which is slightly above the requirements at Addroan Bridge (downstream of the WWTP discharge). Due to the distance downstream of Addroan Bridge, the impact of the Corrofin WWTP contributing to the elevated BOD levels is questionable. The median MRP values for waters in the Phosphorus Regulations are correlated with biological quality ratings, or Q values. The results also show compliance with Q4-5 (Class A) or good water quality with the standard defined for molybdate reactive phosphate (MRP) under the Local Government (Water Pollution) Act, 1977 (Water Quality Standards for Phosphorus Regulations) S.I. 258 of 1998. The median MRP concentration for the Addroan Bridge, downstream of the outfall from the Corrofin WWTP is 0.013mg/litre. Biological quality monitoring (Q rating) in accordance with the Local Government (Water Pollution) Act 1977 Water Quality Standards for Phosphorous Regulations, 1998 is undertaken on a national basis by the E.P.A. Clare County Council also commission Conservation Services to undertake biological monitoring of surface waters. The most recent Q-values recorded in 2007, Q3-4, have not changed from the previous monitoring in 2006 for the sites Corrofin Bridge (Site No. 0300), Ballyteigue Bridge (Site No. 0350) and Addroan Bridge (Site No. 0400). Monitoring data for Lough Atedaun, immediately downstream of Corrofin WWTP, is available for the year 2000 - Lakes of County Clare Report 2000-2001, by TCD November 2001. The results indicate that Lough Atedaun is classified as Mesotrophic status based on maximum Chlorophyll a levels, however if the classification is based on Total Phosphorus (TP) levels in the lake then it is classified as Eutrophic (average TP levels based on four samples only). The overall interim water quality status for the River Fergus downstream of Lough Inchiquin to Ennis is classified by the EPA as Poor status. Clare County Council, during the course of preparing the application for a discharge authorisation, under the Wastewater Discharge (Authorisation) Regulations 2007, (S.I No 684 of 2007) for the Corrofin WWTP, to the EPA assessed the Corrofin agglomeration to identify any facility liable to generate substances listed in Annex X of the Water Framework Directive (2000/60/EC) or relevant pollutants listed in Annex VIII of the Water Framework Directive. Monitoring for these substances was undertaken in April 2009 and results on this monitoring do not indicate any substance on the list was present in the waters of the Fergus or in the discharges to the river from the Corrofin WWTP (see Attachment F.1). No potential source of these pollutants has been identified in the sewer catchment, so it is unlikely that the discharge will contain the listed substances. Results from the survey will be collated and included in the licence application data as soon as may be on receipt of the results of the sampling exercise. The monitoring programs described above provide a good overview of the water quality status in the River Fergus, both upstream and downstream of the WWTP discharge. In conclusion, there is no indication of significant deterioration in quality status of the Fergus River downstream of the discharge from the treatment plant. The monitoring programs described above provide a good overview of the water quality status in the River Fergus, both upstream and downstream of the WWTP discharge. In conclusion, there is no indication of significant deterioration in quality status of the Fergus River downstream of the discharge from the treatment plant.

(vi) Impact of storm overflows A storm overflow is located at Corrofin Bridge. In preparation of a preliminary report by P H Mc Carthy & Partners, it was observed that the existing sewers were in poor condition with low capacities and shallow gradients in some areas leading to surcharging from time to time and the potential for overflow from the system. Any such overflow discharges to the River Fergus to the west of Corrofin Bridge. Sampling of the river was undertaken on April 14th 2009, during the course of preparing the licence application. Results from the survey will be collated and included in the licence application data as soon as may be on receipt of the results of the sampling exercise. The proposals to construct a new WWTP to serve the Corrofin agglomeration includes the decommissioning of this overflow discharge point.

Programme of Improvements The existing Corrofin WWTP serves a population equivalent of 550, and is overloaded and in poor state of repair. In accordance with Clare County Council’s Water Services Investment Programme 2007-2009, Ballyvaughan, Doolin & Corofin are a bundled scheme with a projected cost of €18,025,000. Following approval of a Brief by the Department of the Environment Heritage and Local Government, and compliance with procurement processes, P H Mc Carthy & Partners were appointed to prepare a preliminary report. PJ Tobin & Co, Consulting Engineers, were appointed as Consulting Engineers on 30th December 2002 for the project. Due to the condition of the existing wastewater treatment facilities, the proposed treatment works will not incorporate the existing treatment units. Land adjacent to the existing WWTP has been acquired for the proposed new wastewater treatment plant. The project commenced in 2008 and the network is near completion. The contract for the new wastewater treatment plant has been signed and the contractors are due to submit a final design before construction works commences in 2009. An indicative site layout plan is provided in Attachement G.2 and includes the following:

Stormwater tank Inlet Screen SBR with Phosphate removal Sludge Management Discharge to River Fergus via existing outfall pipe. Decommissioning of existing stormwater overflow at Corrofin Bridge.

In the Preliminary Report carried out by PH McCarthy & Partners in November 2000, the population for Corrofin being served by the WWTP was estimated as 492 during the winter reaching a maximum of 878 in the summer period. The design population for the proposed Corrofin WWTP is 1725 PE, which takes into account a 20 year design horizon. Provision is in place for expansion should the population demand an increase.

Impact Mitigation Under Clare County Council’s Water Services Investment Programme 2007-2009 Ballyvaughan, Doolin & Corofin are a bundled scheme with a projected cost of €18,025,000. Following the approval of a Brief by the Department of the Environment Heritage and Local Government, and compliance with procurement processes, P H Mc Carthys & partners were appointed to prepare a preliminary report. PJ Tobin & Co, Consulting Engineers, Hynes Building St, Augustine Street, Galway were appointed as Consulting Engineers on 30th December 2002 for the project. The Preliminary Report has been completed and the land required for the Wastewater Treatment Plant has been acquired. This project commenced in 2008 and the network is near completion. The contract for the wastewater treatment plant has been signed and contractors will begin work in May 2009. Clare County Council are satisfied that when these works are complete there will be an improvement in water quality and the potential impact on receiving water quality is positive. Clare County Council are satisfied that when these works are complete there will be no deterioration in the chemical status or ecological status (or ecological potential as the case may be) in the receiving body of surface water or deterioration in the chemical status in the receiving body of groundwater. Clare County Council are satisfied that the input into groundwater of hazardous substances, except where it is established that the input concerned is in a quantity and concentration so small as to obviate any present or future danger of deterioration in the quality of the receiving groundwater. Clare County Council are satisfied that when these works are complete and in the case of pollutants that are not hazardous, no further deterioration will take place or result in significant and sustained upward trends in the concentrations of pollutants in groundwater. Clare County Council will ensure that any works that are carried out and when works are complete they will not permanently exclude or compromise the achievement of the objectives established for protected species and natural habitats in the case of European sites where the maintenance or improvement of the status of water is an important factor in their protection or which is inconsistent with the achievement of environmental quality standards established under national Regulations in relation to designated bathing waters, designated shellfish waters, areas designated for the protection of freshwater fish and areas designated for the abstraction of water intended for human consumption.
