Curry and Environs Wastewater Discharge (Authorisation) Regulations, 2007 - Licence Application Habitats Directive Article 6 - Appropriate Assessment Screening Report

1 INTRODUCTION

Sligo County Council submitted the Curry and Environs Wastewater Discharge Licence Application to the EPA on the 21'' December 2009 (ref no. A0316-01) in accordance with the requirements of the Wastewater Discharge (Authorisation) Regulations 2007 (SI 684,2007).

The Curry WWTP is located on the periphery of Curry Village, approximately 100m due east of the Owengarve River. Treated effluent is discharged from the Curry WWTP into the Owengarve River, which forms part of the River Moy cSAC (Site Code: 002298). The Owengarve River flows through the village of Curry and joins the Moy downstream of Cooleen Ford. The WWTP is located within the River Moy cSAC. Refer to Figure 1.1.

Curry and Environs Wastewater Discharge (Authorisation) Regulations, 2007 - Licence Application Habitats Directive Article 6 - Appropriate Assessment Screening Report

On the 14'h December 2010 the EPA issued Sligo County Council with a Regulation 25 (c) (ii) to supply additional information in relation to this application as follows:

RPS has been commissioned by Sligo County Council to prepare an Appropriate Assessment Screening Report in response to the above. The assessment was conducted in line with the following:

The Habitats Directive 92/43/EEC, Article 6(3),

Appropriate Assessment of Plans and Projects in Ireland Guidance for Planning Authorities (DOEHLG 2009, rev 201 0),

Curry and Environs Wastewater Discharge (Authorisation) Regulations, 2007 - Licence Application Habitats Directive Article 6 - Appropriate Assessment Screening Report

2 METHODOLOGY

The Appropriate Assessment process potentially consists of four stages which are shown in Figure 2.1. Stages 1-2 deal with the main requirements for assessment under Article 6(3). Stage 3 may be part of the Article 6(3) Assessment or may be a necessary precursor to Stage 4. Stage 4 is the main derogation step of Article 6(4).

Figure 2.1 Four Stages of Appropriate Assessment

Screening is the process that addresses and records the reasoning and conclusions in relation to the first two tests of Article 6(3):

(i)

(ii)

whether a plan or project is directly connected to or necessary for the management of the site, and whether a plan or project, alone or in combination with other plans and projects, is likely to have significant effects on a Natura 2000 site in view of its conservation objectives.

If the effects are deemed to be significant, potentially significant, or uncertain, or if the screening process becomes overly complicated, then the process must proceed to Stage 2 (AA). Screening should be undertaken without the inclusion of mitigation, unless potential impacts clearly can be avoided through the modification or redesign of the plan or project, in which case the screening process is repeated on the altered plan. The greatest level of evidence and justification will be needed in circumstances when the process ends at screening stage on grounds of no impact. This report fulfils the information necessary to enable the appropriate authority to screen the proposed development for the requirement to prepare an Appropriate Assessment.

The structure of this assessment follows the methodology as recommended in the EPA guidance note: Waste Water Discharge Licensing - Appropriate Assessment (2009) using the following format:

Stage 1 - Screening - - - -

Step 1: Management of the Site Step 2: Description of the Project or Plan Step 3: Characteristics of the Site Step 4: Assessment of Significance

The following section addresses each of these stages of the Screening process individually.

Note: Consideration for the in-combination effects of other Plans and Projects must also be considered as part of the Appropriate Assessment Screening process. A list of those Plans and Projects relevant to this screening report are set out in Appendix A. These plans and projects are referred to and discussed within the text.

Curry and Environs Wastewater Discharge (Authorisation) Regulations, 2007 - Licence Application Habitats Directive Article 6 - Appropriate Assessment Screening Report

4 CONCLUSION

The Curry WWTP is discharging directly to the Owengarve River, which is designated under the River Moy cSAC.

Results of monitoring carried out on the final effluent and on the receiving waters, upstream and downstream of the discharge point, indicate that the discharge is not having a significant negative effect on the water quality of the Owengarve River.

The in-combination effects of both point and diffuse source discharges within the River Moy catchment with the Curry WWTP discharge have been considered. According to the Moy Water Management Unit Action Plan, the Owengarve River is of High Status, indicating that it is not having a significant effect on water quality in the River Moy cSAC, in combination with the other discharges to the Moy catchment.

It is therefore it is concluded that the discharge from the Curry WWTP is not significantly affecting the qualifying interests of the Natura 2000 site. If the plant continues to be monitored and maintained on a regular basis in accordance with the conditions of the Waste Water Discharge Certificate of Authorisation, it is not expected that the discharge will have a significant long-term effect on the qualifying interests of the River Moy cSAC.

The impact of the discharge, in combination with other discharges to the River Moy cSAC, is not considered to be significant, and so a Stage 2 Appropriate Assessment under Article 6(3) of the Habitats Directive is not required in this case.

Owengarve River Assimilative Capacity

Orthophosphate Assimilative Capacity Calculation

Desian Criteria:

The assimilative capacity calculation for Orthophosphate is analysed for compliance with the requirements of the 2009 Surface Waters Regulations. The requirement downstream of the WWTP site on the Owengarve River is to achieve a “High Status”, meaning a maximum Molybdate-Reactive Phosphate Median Concentration of 0.025mg/l. The upstream background levels in the November 2009 sampling showed an Orthophosphate level of 0.49mg/l which is in excess of the regulations. It is therefore proposed that an increase of 0.005 mg/l Orthophosphate be allowed when calculating the WAC for the river.

Design Criteria:

Ammonia level should not exceed 0.09mg/l in the river. The upstream background levels in the November 2009 sampling showed an Ammonia level of 0.42mg/l which is above the maximum allowable concentration. Therefore it is proposed that an increase of 0.05 mg/l Ammonia be allowed when calculating the WAC.

SITE NAME: RIVER MOY

SITE CODE: 002298

This site comprises almost the entire freshwater element of the Moy and its tributaries including both Loughs Conn and Cullin. The system drains a catchment area of 805 sq. km. Most of the site is in Co. Mayo though parts are in west Sligo and north Roscommon. Apart from the Moy itself, other rivers included within the site are the Deel, Bar Deela, Castlehill, Addergoole, Clydagh and Manulla on the west side and the Glenree, Yellow, Strade, Gweestion, Trimogue, Sonnagh, Mullaghanoe, Owengarve, Eighnagh and Owenaher on the east side. The underlying geology is Carboniferous Limestone for the most part though Carboniferous Sandstone is presentat the extreme west of the site with Dalradian Quartzites and schists at the south west. Some of the tributaries at the east, the south of Lough Conn and all Lough Cullin are underlain by granite. There are many towns adjacent to but not within the site. These include Ballina, Crossmolina, Foxford, Swinford, Kiltimagh and Charlestown.

The site is a candidate SAC selected for alluvial wet woodlands and raised bog, both priority habitats on Annex I of the E.U. Habitats Directive. The site is also a candidate SAC selected for old oak woodlands, degraded raised bog and Rhynchosporion, all habitats listed on Annex I of the E.U. Habitats Directive. The site is also selected for the following species listed on Annex I I of the same directive - Atlantic Salmon, Otter, Sea and Brook Lamprey and White-clawed Crayfish.

On the slopes and rising ground around the southern shores of Loughs Conn and Cullin, Oak woodlands are seen. Sessile Oak (Quercus pefraea) is the dominant tree with an understorey of Holly (Ilex aquifolium), Hazel (Corylus avellana) and Birch (Betula pubescens) with some Ash (Fraxinus excelsior). Additional species are associated with the lakeshore such as the whitebeam (Sorbus rupicola), Aspen (Populus fremula), Silver Birch (B. pendula) and the shrubs Guelder Rose (Viburnum opulus), Buckthorn (Rhamnus cafharticus) and Spindle Tree (Euonymus europaeus). The ground flora is usually composed of Bilberry ( Vaccinium myrfillus), Wood Rush (Luzula sylvatica), Wood Sorrel (Oxalis acetosella), Buckler Ferns (Dryopteris aemula and D. dilatafa), Hard Fern (Blechnum spicant), Cow-wheat (Melampyrum spp.) and Bracken (Pteridium aquilinum). The rare Narrow-leaved Helleborine (Cephalanthera longifolia), protected under the Flora Protection Order, 1999, occurs in association with the woodlands. Also found in these woodlands is the snail (Acanthinula lamellata), associated with old natural woodlands.

On higher ground adjacent to the woodlands is blanket bog with scattered shrubs and trees on the drier areas. The rocky knolls often bear Juniper (Juniperus communis) or Gorse (Ulex europaeus), with some unusual rare herb species such as Intermediate Wintergreen (Pyrola media) and Lesser Twayblade (Listera cordata).

Within the site are a number of raised bogs including those at Kilgarriff, Gowlaun, Derrynabrock, Tawnaghbeg and Cloongoonagh. These are examples of raised bogs at the north-western edge of the spectrum and possess many of the species typical of such in Ireland, including an abundance of Bog Asphodel (Narthecium ossifragum), Carnation Sedge (Carex panicea) and the moss Campylopus atrovirens. Some of the bogs include significant areas of active raised bog habitat. Well developed pool and hummock systems with quaking mats of bog mosses (Sphagnum spp.), Bog Asphodel (Narthecium ossifragum) and White Beaked-sedge (Rhynchospora alba) are present. Many of the pools contain a diversity of plant species, including Bogbean (Menyanthes trifoliafa), the bog moss Sphagnum cuspidatum, Campylopus atrovirens, Common Cottongrass (Eriophorum angustifolium), Great Sundew (Drosera anglica) and occasional Lesser Bladderwort (Utricularia minor). Several of the hummock-forming mosses (Sphagnum fuscum and S. imbricatum) which occur here are quite rare in this region and add to the scientific interest of the bogs within the overall site.

Depressions on the bogs, pool edges and erosion channels, where the vegetation is dominated by White Beaked-sedge (Rhynchospora alba) comprise the habitat Rhynchosporion. Associated species in this habitat at the site include Bog Asphodel, Sundews, Deergrass (Scirpus cespifosus) and Carnation Sedge.

Degraded raised bog is present where the hydrology of the uncut bogs, has been affected by peat cutting and other land use activities in the surrounding area such as afforestation and associated drainage and also by the Moy arterial drainage. Species typical of the active raised bog habitat are still

present but the relative abundance of them is different. A typical example of the degraded habitat, where drying has occurred at the edge of the high bog, contains an abundance and more uniform cover of Ling Heather (Calluna vulgaris), Carnation Sedge, Deergrass and sometimes Bogmyrtle (Myrica gale). Occurring in association with the uncut high bog are areas of wet regenerating cutover bog with species such as Common Cottongrass, bog mosses and Sundew, while on the drier areas, the vegetation is mostly dominated by Purple Moor-grass (Molinia caerulea). Natural regeneration with peat-forming capability will be possible over time with some restorative measures.

The open water of Loughs Conn and Cullin is moderately hard with relatively low colour and good transparency. The phytpoplankton of the lake is dominated by diatoms and blue-green algae and there is evidence that the latter group is more common now than in former years. This indicates that nutrient inflow is occurring. Arctic Charr (Salvelinus alpinus) appear to have disappeared from the lake over

eutrification process. Stoneworts still present include Chara aspera, C. delicatula and Nitella cf. opaca. Other plants found in the shallower portions are the pondweeds. Where there is a peat influence Intermediate Bladderwort (Utricularia intermedia) is characteristic while Water Lobelia (Lobelia dorfmanna) often grows in sand. Narrow reedbeds and patches of Yellow Water-lily (Nuphar lutea) occur in some of the bays.

Drainage of the Moy in the 60s lowered the level of the lakes, exposing wide areas of stony shoreline and wet grassland, which are liable to flooding in winter. This increased the habitat diversity of the shoreline and created a number of marginal wetlands, including fens and marshes. Plant species of note in the lake-margin include Heath Cudweed (Omalotheca sylvatica), Great Burnet (Sanguisorba officinalis) and Irish Lady’s-tresses (Spiranthes romanzofiana). These three species are listed on the Irish Red Data list and are protected under the Flora Protection Order 1999.

Other habitats present within the site include wet grassland dominated by Rushes (Juncus spp.) grading into species-rich marsh in which sedges are common. Among the other species found in this habitat are Yellow Iris (Iris pseudacorus), Water Mint (Mentha aquatica), Purple Loosestrife (Lythrum salicaria) and Soft Rush (Juncus effusus).

Grey Willow (Salix cinerea) scrub and pockets of wet woodland dominated by Alder (Alnus glutinosa) have become established in places throughout the site. Ash (fraxinus excelsior) and Birch (Betula pubescens) are common in the latter and the ground flora is typical of wet woodland with Meadowsweet (Filipendula ulmaria), Angelica (Angelica sylvestris), Yellow Iris, Horsetail (Equisetum spp.) and occasional tussocks of Greater Tussock-sedge (Carex paniculata).

the same period of time. The changes in Lough Conn appear to represent an early phase in the 1

Small pockets of conifer plantation, close to the lakes and along the strip both sides of the rivers, are included in the site.

The Moy system is one of Ireland’s premier salmon waters and it also encompasses two of Ireland’s best lake trout fisheries in Loughs Conn and Cullin. Although the Atlantic Salmon (Salmo salar) is still fished commercially in Ireland, it is considered to be endangered or locally threatened elsewhere in Europe and is listed on Annex I I of the Habitats Directive. The Moy is a most productive catchment in salmon terms and this can be attributed to its being a fingered system with a multiplicity of 1st to 5‘h order tributaries which are large enough to support salmonids e 2 years of age while at the same time being too small to support significant adult trout numbers and are therefore highly productive in salmonid nursery terms.

Salmon run the Moy every month of the year. Both multi-sea-winter fish and grilse are present. The salmon fishing season is 1st February to 30th September. The peak of the spring fishing is in April and the grilse begin running in early May. The average weight of the spring fish is 9 Ib and the grilse range from about 3-7 Ib. In general spring fish are found more frequently in the rivers at the western extent of the Moy system.

The Arctic Char (Salvelinus alpinus), an interesting relict species from the last ice age, which is listed as threatened in the Irish Red Data Book has been recorded from Lough Conn and in only a few other lakes in Ireland. The latest reports suggest that it may now have disappeared from the site.

The site is also important for the presence of three other species listed on Annex I I of the E.U. Habitats Directive, namely Sea Lamprey (Petromyzon marinus), Otter (Lutra lufra) and White-clawed Crayfish (Austropotamobius pallipes). The Sea Lamprey is regularly encountered in the lower stretches of the river around Ballina, while the otter and crayfish are widespread throughout the system. In addition, the site also supports many more of the mammal species occurring in Ireland. Those which are listed in the Irish Red Data Book include Pine Marten, Badger, Irish Hare and Daubenton’s Bat. Common Frog, another Red Data Book species, also occurs within the site.

Loughs Conn and Cullin support important concentrations of wintering waterfowl and both are designated Special Protection Areas. A nationally important population of the Annex I species Greenland White-fronted Geese (average 113 over 6 winters 1994/95 to 1999/00) is centred on Lough Conn. Whooper Swans also occur (numbers range between 25 to 50), along with nationally important populations of Tufted Duck 635, Goldeneye 189 and Coot 464. A range of other species occur on the lakes in regionally important concentrations, notably Wigeon 303, teal 154, Mallard 225, Pochard 182, Lapwing (>I ,000) and Curlew 464. Golden Plover also frequent the lakes, with numbers ranging between 700 and 1,000.

Loughs Conn and Cullin are one of the few breeding sites for Common Scoter in Ireland. Breeding has occurred on Lough Conn since about the 1940s when about 20-30 pairs were known. A census in 1983 recorded 29 pairs. Breeding was first proved on Lough Cullin in 1983 when 24 pairs were recorded. In 1995, 24-26 pairs were recorded at Lough Conn and 5 pairs at Lough Cullin. The latest survey in 1999 gives a total of 30 birds for both lakes, comprising only 5 pairs, 18 unpaired males and 2 unpaired females. The reason for the decline is not known but may be due to predation by mink, possible changes in food supply and/or redistribution to other sites. The Common Scoter is a Red listed species.

Agriculture, with particular emphasis on grazing, is the main landuse along the Moy. Much of the grassland is unimproved but improved grassland and silage are also present. The spreading of slurry and fertiliser poses a threat to the water quality of this salmonid river and to the large lakes. Fishing is a main tourist attraction on the Moy and there are a large number of Angler Associations, some with a number of beats. Fishing stands and styles have been erected in places. The North Western Regional Fishery Board have erected fencing along selected stretches of the river as part of their salmonid enhancement programme. Other aspects of tourism are concentrated around Loughs Conn and Cullin.

Afforestation has occurred in the past around the shores of Loughs Conn and Cullin. The coniferous trees are due for harvesting shortly. It is proposed to replant with native tree species in this area. Forestry is also present along many of the tributaries and in particular along the headwaters of the Deel. Forestry poses a threat in that sedimentation and acidification occurs. Sedimentation can cover the gravel beds resulting in a loss of suitable spawning grounds. The Moy has been arterially dredged in the 60s. Water levels have been reduced since that time. This is particularly evident along the shores of Loughs Conn and Cullin and in the canal-like appearance of some river stretches. Ongoing maintenance dredging is carried out along stretches of the river system where the gradient is low. This is extremely destructive to salmonid habitat in the area.

The site supports populations of several species listed on Annex II of the EU Habitats Directive, and habitats listed on Annex I of this directive, as well as examples of other important habitats. The presence of a fine example of broad-leaved woodland in this part of the country increases the overall habitat diversity and adds to the ecological value of the site as does the presence of the range of nationally rare and Red Data Book plant and animal species.
