EPA Export 26-07-2013:23:44:07 1. INTRODUCTION

The present report by Pascal Sweeney, Consultant Ecologist, was commissioned by Carlow County Council. The discharge from Old Leighlin Waste Water Treatment Plant enters the Old Leighlin

Stream (also known as the Madlin River), a tributary of the River Barrow, within Special Area of Conservation 002 162 (River Barrow and River Nore SAC). Because the biological water quality of the Old Leighlin Stream was found to be unsatisfactory by EPA in 2009 at the site near its confluence with the River Barrow (the only site assessed on the watercourse that year), the possibility of significant effects of the discharge on the European Site cannot be eliminated and the

precautionary principle must apply. Under Article 6(3) of the EU Habitats Directive, there is a requirement for an Appropriate Assessment of the implications for the designated site of a discharge such as this, in view of the site's conservation objectives.

The objective of this report is the assessment of the Old Leighlin Stream in order to establish the current effect, if any, of the existing discharge on the biota of the river and the implications of any such effects for protected habitats and species within SAC 002 162. Potential effects include both direct damage, such as from toxic impacts, and indirect damage from impacts on water quality.

The scope of this assessment is:

1 0 Invertebrate identification to the level necessary for the EPA Q-scheme, upstream and

I downstream of the outfall location. For inspection purposes only. Consent of copyright owner required for any other use.

li Biological water quality assessment, based on the macroinvertebrate fauna and the establishment of Q-values in accordance with the procedures of the EPA, upstream and downstream of the outfall location.

k 0 Impacts of the discharge on invertebrate species composition, and biodiversity. x dl 0 Likely occurrence of protected aquatic species at and downstream of the proposed discharge point, based on habitat suitability and available records. Likely impacts of the discharge on protected aquatic species and habitats. Cumulative effects on the qualifying interests of the Natura 2000 site. Measures to mitigate negative impacts on the protected species and habitats.

EPA Export 26-07-2013:23:44:07 2. METHODOLOGY

2.1 Rationale for Methodology Because the Old Leighlin WWTP is already in existence, the current impact on the biota of the receiving environment can be directly assessed by biological methods which measure the effects of pollution (as distinct from chemical methods which measure the causes of pollution). The information obtained from biological sampling reflects the prevailing water-quality conditions in the period leading up to that sampling event. Clabby et al. (2006) state: “just two biological samples per annum (winter and summer) would normally provide a reasonably accurate assessment ofaverage water quality ”.

2.2 Biological Sampling Sites Two sites, suitable for biological assessment, were established in the Old Leighlin Stream. Site 1 is immediately upstream of the Old Leighlin WWTP effluent outfall. Site 2 is c. 70m downstream of the effluent outfall.

2.3 Field and Laboratory Procedures 2.3.1 Macroinvertebrate sampling and Q-rating Field work was carried out on 17 March, 2010. At both of the sites, a qualitative assessment of habitat conditions was first carried out. Site information is given in Appendix 1 and photographs are I shown in Appendix 2. A kick sample was For inspection taken purposes at each only. site by the standard EPA method, using a Consent of copyright owner required for any other use. hand-net (mesh size lmm.). The contents of the sample net were checked for protected species and any found were immediately returned to the water. Samples were live sorted for a half hour each 6’ and macroinvertebrates were preserved in alcohol. Macroinvertebrates were identified using an hi Olympus dissecting microscope. A list of taxonomic keys used for identification is given in Appendix 7. Based on the relative abundance of indicator species, a Q-value was determined for each site, using the methodology of the EPA (Toner et al, 2005). The preserved samples were IF retained and stored in vials so that they may be checked, if necessary, in the future. L

2.3.2 Plants ba At both sites, the percentage cover of the substratum with each plant taxon was estimated.

4 OLD LEIGHLIN WASTE WATER WORKS Appropriate Assessment of Biological Impacts F EPA Export 26-07-2013:23:44:07 2.3.3 Protected species Available records of species listed in Annex I1 of the EU Habitats Directive were checked. The habitat quality for any of these species likely to be present at or within one kilometre downstream of the discharge point was assessed as follows:

U The habitat quality for Atlantic salmon (Sulmo sulur) was assessed, based on the criteria U outlined by Kennedy (1 984) and by Bardonnet, A. and Bagliniere, J. (2000) for the physical instream requirements of this species for spawning, nursery and adult habitat. The habitat quality for the three species of lamprey, the brook lamprey (Lumpetru planeri), river lamprey (Lampetru fluviutilis), sea lamprey (Petrumyzun murinus) was assessed, based on the criteria outlined by Maitland (1980) and by Johns (2002) for the physical instream requirements of these species for spawning, nursery and adult habitat. The habitat quality for crayfish (Austropotamobius pallipes) was assessed, based on the criteria outlined by Holdich (2003).

2.4 Use of Available Chemical Data Results of routine chemical monitoring of the river water in 2009 by Carlow County Council were examined to help in the interpretation of the biological analysis (Appendix 6).

EPA Export 26-07-2013:23:44:07 3. RESULTS 3.1 Macroinvertebrates The macroinvertebrate community recorded at each site, giving abundances for each site, along with Q-values, is presented in Appendix 3.

At both sampling sites, Group A (pollution sensitive) forms were very well represented, with three taxa present, one of which (the mayfly nymph Rhithrogena sp.) being the most abundant species present. Group B (relatively pollution sensitive) was also well represented at both sites. Groups D (pollution tolerant) and E (most pollution tolerant) were absent. Both sites are rated as Q4-5 (Unpolluted)

Overall, the macroinvertebrate results from Sites 1 and Site 2 indicates that the discharge from Old Leighlin WWTP is currently having no negative impact on the biological water quality of the Old Leighlin Stream.

3.2 Plants The plants recorded at each site are presented in Appendix 4. The aquatic flora present at the time of the survey does not indicate any effects of the discharge. However, because of the time of year that fieldwork was carried out, it is important that available chemical data (Appendix 6) also be

In 2009, mean orthophosphate levels recorded were 0.06mg/l P both upstream and downstream of the outfall. Mean nitrate levels recorded were 5mg/l N both upstream and downstream of the outfall. These chemical data do not show any significant difference in plant nutrient concentrations between corresponding sites upstream and downstream of the outfall, which indicates that plant growth would not be affected

3.3 Protected Habitats and Species. In this section, the impact of Old Leighlin WWTP discharge on each of the habitats and species for which the SAC is designated, is estimated. While the zone of potentially highest impact was taken as being from the discharge point to lkm downstream and this section of river was the main focus of the detailed investigation, the entire downstream freshwater section of the river was considered

EPA Export 26-07-2013:23:44:07 when assessing the presence of protected habitats and species and the potential effects of the discharge on these.

The Site Synopsis for the River Barrow and River Nore SAC states: “The site is a candidate SAC selected for alluvial wet woodlands and petrifiing springs, priority habitats on Annex I of the E. U. Habitats Directive. The site is also selected as a candidate SAC for old oak woodlands, floating river vegetation, estuary, tidal mudJlats, Salicornia mudJlats, Atlantic salt meadows, Mediterranean salt meadows, dry heath and eutrophic tall herbs, all habitats listed on Annex I of the E. U. Habitats Directive. The site is also selected for the following species listed

on Annex 11 of the same directive - Sea Lamprey, River Lamprey, Brook Lamprey, Freshwater Pearl Mussel, Nore Freshwater Pearl Mussel, Crayfish, Twaite Shad, Atlantic Salmon, Otter, Vertigo moulinsiana and the plant Killarney Fern. ’’

Several of the species and habitats listed above are terrestrial and could not be affected by the Old Leighlin WWTP discharge. Some are estuarine, in which cases the distance from the outfall to the w saline waters (over 40km) must be taken into account when assessing the likelihood of any impacts.

A more substantial increase in plant nutrients could cause an increase in the competitive interactions between plant species, resulting in a loss of species. However, as no effects of the discharge on the flora in close proximity to the outfall were detected, and as the available chemical data do not show a significant increase in plant nutrients downstream of the outfall, it is considered that the discharge is currently having no impacts on floating river vegetation.

However, as no significant effects of the discharge were detected close to the outfall and as the available chemical data do not show an increase in plant nutrients downstream of the outfall, and given the distance from Old Leighlin to saline waters, no impacts are considered likely.

3.3b Protected Species. Of the Annex I1 species listed in the Site Synopsis, the first five considered below could not be significantly affected by discharge from the Old Leighlin WWTP.

Freshwater Pearl Mussel (Margaritifera margaritifera). The freshwater pearl mussel is apparently now extinct in the main channel of the River Barrow (Lucey, 1998). A live specimen of freshwater pearl mussel was last found in the River Barrow in

1991, c. 5km upstream of Graiguenamanagh (Grid Ref. S734 477). This location is downstream of the confluence of the Mountain River, which supports a freshwater pearl mussel population and from which this specimen was probably washed into the River Barrow (E. Moorkens, pers. comm.).

Within SAC 002162, the Nore freshwater pearl mussel is a sub-species which occurs only in a 1 Okm stretch of the main channel the River Nore and is not in any part of the River Barrow. of I

Twaite Shad (Alosafallax).

Twaite shad is an anadromous fish which enters large estuaries in late April or May to spawn in I, gravels near the end of the freshwater reaches (Whelan, 1989). Doherty et aZ. (2004) state that in Ireland the only known spawning population of twaite shad occurs in the upper tidal limit of the River Barrow, below the weir at Saint Mullin's, with considerable variation in spawning activity depending upon water temperature, tidal strength and river flow. The main threat to the shad population in the River Barrow is the recently arrived Asian clam (Sweeney, 2010) which is likely to have a very significant negative impact on spawning areas.

8 OLD LEIGHLIN WASTE WATER WORKS Appropriate Assessment of Biological Impacts

EPA Export 26-07-2013:23:44:07 As no decline in biological water quality was found, and given the distance from Old Leighlin WWTP to the upstream end of the known distribution range of this species, no impacts are considered likely.

Moulins’ Whorl Snail (Vertigo moulinsiana) Vertigo moulinsiana is found in calcareous wetlands, usually adjacent to lowland rivers and lakes (Kerney, 1999). However, as it is not an aquatic species, it is not susceptible to changes in quality of river water.

Killarney Fern (Trichomanes speciosum) Killarney fern is a terrestrial species, found on very sheltered, damp rock faces (Stace, 1991) and could not be affected by the river water quality.

Sea Lamprey (Petromyzon marinus), River Lamprey (Lampreta fluviatilis) and Brook Lamprey (Lampretaplaneri).

King (2006) recorded juvenile sea and brook/river lampreys in the Old Leighlin Stream. In the U

Crayfish are fairly well distributed in the River Barrow catchment (Demers et al., 2005). None were found at Sites 1 or 2 in the present survey, although the habitat was rated as good for this species.

As no decline in biological water quality was found, it is considered that the discharge is currently having no impacts on crayfish, if they are present in this watercourse.

Atlantic Salmon (Salmo salar). O’Reilly (2002) states that the River Barrow is a fair to good salmon river. There is good salmon spawning and nursery habitat in the Old Leighlin Stream. The River Barrow is not a Salmonid Water designated under the European Communities (Quality of Salmonid Waters) Regulations of 1988 (S.I. No. 293 of 1988). The chemical data presented in Appendix 6 are within the standards specified for compliance with these regulations in Salmonid Waters, both upstream and downstream of the outfall for the following parameters for which data are available: BODS, Suspended Solids, OLD LEIGHLIN WASTE WATER WORKS Appropriate Assessment of Biological Impacts 9

EPA Export 26-07-2013:23:44:07 Total Ammonium. The egg and juvenile stages of the salmon life cycle are very vulnerable to deteriorations in water quality (Hendry and Cragg-Hine, 2003). A significant drop in water quality would also negatively affect adult salmon. However, as no decline in biological water quality was found, it is considered that the discharge is currently having no impacts on salmon.

Otter (Lutra lutra). Within the South Eastern River Basin District, which includes the River Barrow Barrow, Baily and Rochford (2006) recorded positive results at nearly 73% of the sites surveyed, indicating a widespread distribution of the species. If water quality dropped to the extent that the abundance of prey species were significantly affected, otters could be negatively impacted. However, as the discharge does not appear to be negatively impacting on prey species, it is considered that the discharge is currently having no impacts on otters.

EPA Export 26-07-2013:23:44:08.Lw 4. CONCLUSIONS 4.1 Conservation Objectives. Summarising the main threats to the designated site, the Site Synopsis for The River Barrow and River Nore SAC states: “The main threats to the site and current damaging activities include high inputs of nutrients into the river system from agricultural run-off and several sewage plants, overgrazing within the woodland areas, and invasion by non-native species, for example Cherry Laurel and Rhododendron (Rhododendronponticum). The water quality of the site remains vulnerable. Good quality water is necessary to maintain the populations of the Annex I1 animal species listed above. Good quality is dependent on controlling fertilisation of the grasslands, particularly along the Nore. It also requires that sewage be properly treated before discharge. Drainage activities in the catchment can lead to flash floods which can damage the many Annex I1 species present. Capital and maintenance dredging within the lower reaches of the system pose a threat to migrating fish species such as lamprey and shad. Land reclamation also poses a threat to the salt meadows and the populations of legally protected species therein.”

The relevant conservation objective pertaining to the discharge to Old Leighlin WWTP must therefore be to avoid impacts from high BOD, suspended solids and nutrients by proper treatment of the effluent before discharge to the river. The fact that no biological impact of the discharge was detected in the present survey, indicates that this conservation objective is currently being achieved.

4.2 Cumulative Impacts. Point sources, diffuse runoff and inputs from tributaries of unsatisfactory water quality are affecting the biological water quality of the River Barrow along the course of the river. This can be seen in the EPA Q-ratings (Appendix 5). In the Old Loughlin Stream, unsatisfactory conditions have been recorded at EPA Site 0700 (Madlin Br.), the lowest site on the watercourse, over the past decade. Results of the current survey show that the discharge from the WWTP is not contributing to this problem. Some other source of pollution is evidently present upstream of Madlin Br. The slightly

<”& polluted conditions of the lower end of the Old Leighlin Stream is not reflected in the 2009 EPA Q- IIUI values recorded in the main channel of the River Barrow, where both Site 2680, upstream of the confluence and Site 2900 downstream of the confluence were rated as 44.

The following facilities in the catchment of the River Barrow between Athy and New Ross have waste licences:

In the present survey, no biological impact of the Old Leighlin WWTP discharge was detected. As c the WWTP is not having any measurable biological impact in the stretch of river to which it discharges, it is considered that it would not add to the cumulative impact on the Natura 2000 site and its conservation objectives.

EPA Export 26-07-2013:23:44:08 4.3 Mitigation Measures. The lack of detected biological impacts on the river indicates that the measures in place within Old Leighlin WWTP are adequate to maintain the discharge at a quality that does not significantly impact on the conservation objectives of the Natura 2000 site. Details of mitigation measures within Old Leighlin WWTP, provided by Carlow County Council, are presented in Appendix 8. In any future changes made to Old Leighlin WWTP in terms of capacity or design that could impact on the effluent quality, it must be ensured that mitigation measures are adequate to avoid inputs to the river that would negatively impact on the conservation objectives of the SAC.

5. NON TECHNICAL SUMMARY

A biological assessment was carried out in order to assess the current effect, if any, of the discharge from Old Leighlin Waste Water Treatment Plant (WWTP) on the biota of the Old I Leighlin Stream (Madlin River) and the implications of any such effects for protected habitats and species within this Special Area of Conservation (SAC). Sampling was I undertaken on 17 March, 2010, with samples taken at two river sites, upstream and downstream of the Old Leighlin WWTP outfall.

Biological water quality assessment indicates unpolluted conditions at both sites surveyed.

Analysis of the faunal communities upstream and downstream of the outfall shows that the effluent from St. Mullin’s WWTP is currently having no significant impact on the biological water quality of the river.

Six species and one habitat which are listed for protection under the EU Habitats Directive I were identified as being present, or likely to be present at or downstream of the Old Leighlin WWTP outfall.

As the discharge is not resulting For in inspection any purposessignificant only. difference between the biota upstream Consent of copyright owner required for any other use. and downstream of the discharge point, it appears highly unlikely that there could be any

negative effects, either direct or cumulative, of the effluent on the protected habitats and R

EPA Export 26-07-2013:23:44:09 May 2010

Old Leighlin and the Catchment Area

Old Leighlin is located 10 kms south-west of Carlow Town. The WWTP is located beside the River Madlin and accessed through a field from the Public Road. Carlow County Council have a Right of Way to the WWTP. Effluent from the existing treatment works discharges to the Madlin River which flows in an easterly direction before discharging into the River Barrow lkm downstream of Leighlinbridge.

The catchment area consists of the village of Old Leighlin. No areas outside of the village of Old Leighlin are pumped or transferred to this WWTP.

Old Leighlin Waste Water Treatment Plant

The existing WWTP had been built in 1994 for a designed capacity of 200pe. The WWTP currently is receiving a load of approximately over 140pe.

For inspection purposes only. The existing works at Old LeighlinConsent of copyrightconsists owner of required a secondaryfor any other use. treatment works using an extended aeration process and the return of activated sludge.

The actual plant consists of a Circular Tank, 11.2m3 in which Aeration, Settlement and Decanting occur on a preset cycle.

There are sludge drying beds but these are not used and as required sludge is tankered to Muinebheag WWTP for treatment.

There is a storm water overflow in the inlet manhole and there is an influent pumping station which lifts the flow into the aeration tank. The aeration tank is aerated by a floating surface F aerator which moves up and down. Yi

EPA Export 26-07-2013:23:44:09 Operation of the Works

The Old Leighlin Waste Water Plant is operated by the following staff:

e 1 No Caretaker.

The Caretaker also operates and manages two other waste water plants.

The caretaker reports to the Area Engineer for the Central Area. The Area Engineer is the Budget Holder for the plant and arranges all works pertaining to the plant.

The caretaker for Old Leighlin also is caretaker for Raheendoran and Leighlinbridge Sewerage Schemes.

The caretaker is also responsible for the sewer network. The Area Engineer supplements the

d caretaker with additional resources as required.

All sampling is done by the County Council Technician responsible for testing and sampling county wide. Testing is done by an accredited laboratory. For inspection purposes only. Consent of copyright owner required for any other use.

Sources of Emissions from the Waste Water Works

The WWTW discharges final effluent and storm water into the Madlin River, about 3kms upstream from where the Madlin River joins the River Barrow. There are no other emissions to the environment except for a minimal level of odour associated with a secondary treatment waste water works, there is no primary treatment and therefore no odours associated with primary sludges.

Old Leighlin Waste Water Works - Mitigation Measures 3

EPA Export 26-07-2013:23:44:09 The effluent being transferred to the WWTP is a typical municipal sewage with no industrial or agricultural type discharges such as food processing or any other non municipal type effluent.

The treated effluent entering the Madlin River is consistent with the type of effluent associated with an activated sludge type process. There are no loadings coming to the WWTP that would be radically different from typical municipal sewage.

The potential loadings to the receiving waters are BOD, COD, Suspended Solids, Phosphorus, Nitrates and Ammonia.

Phosphorus loadings would be greatly reduced by the injection of Ferric Sulphate at the WWTP.

However there is no ferric dosing at the existing WWTP.

The Old Leighlin WWTP is currently struggling to come within the general parameters for BOD and S.S. of 25mgll and 35mg/l as set out in the Urban Waste Water Regulations.

For inspection purposes only. Consent of copyright owner required for any other use. The Urban Waste Water Regulations would specify “appropriate treatment” for a WWTP the size of Old Leighlin.

Currently the WWTP does not have a storm water treatment facilities.

Water Framework Directive (WFD;

The objectives of the Water Framework Directive (WFD) are to protect all high status waters, P prevent further deterioration of all waters and to restore degraded surface and ground waters bn to good status by 2015. A major programme is under way to achieve this target.

Old Leighlin Waste Water Works - Mitigation Measures 4

EPA Export 26-07-2013:23:44:09 In order to comply with the requirements of the Water Framework Directive (WFD, the WWTP at Old Leighlin will need to be upgraded to a WWTP that will produce a good quality effluent to comply with all National and European Legislation.

Urban Waste Water Treatment Directive (UWWTD)

The Old Leighlin Waste Water Treatment Plant is currently not in compliance with all requirements under the UWWTD.

There are no facilities for the treatment of stormwater at the WWTP at present.

The current results for the Effluent are also well outside even the standard parameters of 25mg/1/35mg/l. We have included results in the application.

The primary discharge point from Old Leighlin Waste Water Treatment Plant discharges into the Madlin River which flows into the River Barrow.

The Madlin River rises on the Castlecomer Plateau to the southwest of Old Leighlin Village and flows in an easterly direction to join the River Barrow 1 km downstream of Leighlinbridge. The EPA have a monitoring station 0700 at bridge upstream of River Barrow Confluence.
