the Blackwater River. The Blackwzter River is a designated Special k e a of
Conservation, Site Code 002170, li Site Synopsis on which the designa~ioii was based
is aaached. The reasons for the selection oE the site as an SAC JiiclucZed the presence
of the following water-based animd species:
Sea Lam.prey, River Lamprey, Brook Lamprey,
Freshwater P e d Mussel, Crayfish, Twaite Sliad,
Atlantic Sal1non and O'der.
The Site Synopsis makes no explicit reference to the Duvglasha River, but the
lower reaches ofthe Duvglasha, from about 1.5 Itm upstream down to its confluence
with the Blackwater, are included in the Blackwater River SAC, as shown in the
NPIVS map ofthe SAC. This is ~ - d ~ ~ b t - e d l y due to the presence of one or more of the
above-Iisted anima1 species in the Duvglashsa River. The Bla&wakr River: cztchment
is protected under the Freshwater Pearl Mussel Regulations, because of the presence
of endsliigered populations of that species in thle River md its tributaries, though there
is no record of Freshwater Pearl Mussel being found in the Duvglasha.
The result ofthe screening protocol set out in the Flow Chart in Appendix I a
is that the development is iiz or close to a Special Area of Conservation and therefore
that its impact is to be assessed, There are four possible designated stages to an
kppropriate Assessment as set cut in the extracts frum the EPA Guidance Dcmmient
on the following 'WO pages:

Stage 3 - Assessment of Akteraative Sslestioaas
This stage examines alternsltive ways of achieving the objectives of the $an or project
that avoid adverse impacts on the integrity ofthe European Site.
Stage 4 " &aessmeRt whe.n*e no alternative aoliutions exist
Are there imperative reasons oToverrjdiiig public interest (LROPI)?
Are there human health or safety considerations or important environmentnl benefits?
Stage 1 - Screaming The first stage of the appropriate assessment process is screening. This stage
idenMies the likely impacts on European Sites o f a plan or project either done 01' in
combination and considers whether these effects are likely to be significant.
Step 1: ~~~~~~~~~~~~~ of the site
Is the plan or prqject directly connected with or necessary to the management of
the site for nature conservation? (The answer is always Ab for waste water
discharges).

step 3: QlhWraCleg.is$i@s of the site
This step mpires identification of the impacts oftl-ie project 01' plan on a
European Site(s) by chsracterising ',l?c site as a whole or those areas where
impacts are most likely to occur. In addition to consideration of the cuinulative
effecis on a European Site(s), consideration must also be given to direct, indirect,
short and long-term, isolated and interactive effects.
Step 4: Aasessaa3esa% of sigoifi'ncance
The assessment ofthe Iilcelihood of significant effects of a proposed or existing
plan or project on a European Site(s) can be eornpktecl by referring to Circular
LW08 ' ~YQW Sewice,s Jm~e,siii;lenf and Rural Wafw Pro,gi.nrimes - Proodeerion of 3Wwd ZIeritoge nisldNcrtionaI Monui?zei7f,r' issued by the D-epai-tmcnt of
Environment, Heritage and Local Government. 111 particular, the flow diagram in
Appendix I should be completed and the results of each section recorded.
If no significant effects are likely then no further assessment is required prior to
the authorisation ofthe plan or project. There ~iaust be no reasoliable scientific
doubt that the plan or project does not have an effect on a European Site. This
decision should be reasoned and recorded. If significmt effects are likely then au2
appr~priate assessment must be carried out. I n addition, if the liltefihooci of
significant effects is In doubt then the pz~~cwtt~ionasy prirwipk appf ies and an
appropikte assessment must be carried out.

Identify all the elenleiits ofthe project 01' plan alone or iii combination with other
plans or projects that have the potential for having sigiiificant effects on the site. 'The
geogaphicai scope oftlie plan or project as well as the European Sites that inay be cffected
rnnust be identified. The European Site or Sites that could be affected should be described.
In line with the EPA Guidance Note, this Screening procedure reelates on1y to
activities that have or can Ixwe an impact on the aquatic environment. The primary
activity in question is the discharge OF trea.ted wa.stewater from Lornbardstown MilI. The
characteristics af the treated wastewater and the Con.ditions under \vhEch it i s dischaxgeti
are farlly specified in the existing Discharge Licence. The discharge fium the wastewater
treatment plant is combined with uncontaminated cooling water and surface water before
discharge to the river. The current Iicence conditions for both are as shown in Tabfe 1.
(next page). The geographical location of the discharge is specified in the localioiz maps
and site maps submitted to the County Council as part of the licensing process.
This Assessment requires that reference be made to other discharges which 'in
combination' with the discharge from Lornbardstown Milf, could have an impact on the
receiving water, either the Dravglashsa or Blackwater Rivers, There are many disdmrges "to
the Elackwater along its eiztire length, but the prjmary attention liere rnust necessarily be
on any other discharges in the vicinity oftfie discharge 60rn Lombardsiow Mill. No
such discharges of any sigmiificaizce are hiown to occur to the D~uvgIasha River. 'Yhei+e is a
disclzarge: from the agg1omcmtior-r (mr~nicipa). area) of I.,ornbardstown, through a septic
tank, to the Blacrkwafer River just upstream ofthe cn:ifluence with the Ihvglzshz.

-:-- Step 3: oZhaii.ac$eristics of the site
This step requires identification ofehe impacts ofehe project or pian on a European Sitc(s) by
characterising the site as a whole or those areas where impacts are niost Iilrciy to occur. In
addition to consideration of the cumulative effects on a European Site(s), considemtion must
also be given to direct, indirect, short and long-term, isolated and inleractive effects.
The SAC that could be affected by the discharge is described earlies in this
Section, and in more detail in the attached Site Syiiopsis for the Blackwater River (Site
Code 0021 70). The area where the iizlpact oftlie discharge is most iikely to occur i s in the
Duvgfasha River immediately downstremi of the dischai:ge point. The most importgn'c
cl~araacteristics ofthe river in this area are its flow a.n$ ifs quality. The flows and water
quality in the river have beer1 ascertained using the E f A Mydratool fadity, and results
are set o~zt in the accompanyiiig assessment of AssimiIative Cz,pncity,

The Blackwater rises in boggy land of east Merry , where Narnwian grits arid shales build the law heather-covered plateaux. Near IC.smlurk the plateaux eizclose a basil? of productive Coal Measures. On Ieaving the Namurian rocks the Blackwater tunsls eastwads along the northern slopes of the Boggeraghs before entering the narrow limestone strike vale at Maliow. The valley deepens as first the Nagles Mountains
th is stretch of the Blackwater Valley include lirnestone cliffs and caves near the villages and sn~.aiZ towns of KiIla.tzrllen. and Ballyhooly; the KiIIavulfen caves caiztah fossil material from the end ofthe gIacia.1 period. The associated basic soils in this area support the grow'L1i of plant. camxmitics which are rare in Cork becawe in general the county's rocks are acidic. At Cappoquia the river suddenly turns south and cuts tlxough high ridges of OM Red Sandstone.

A small stand of Yew (Tams liaccafw) woodland, a rare habitat in Ireland and the EU, occurs within the site. This is on a Zirnestone ridge at Dromana, near Viilierstown. While there are some patches of the wosd with a campy of Yew and some vwy old trees, the q u d i t y is geneidly poor due io the dominance of non-native aiid invasive species such as Sycamore, Beech an.d Douglas Fir QPsezidoi,sug~7 menzs;c;isii>. However, the fiimre prospect for this Yew wood i s good as the site is pr~posed fix restoxtion under a Coiliti: EU Life P~*ograrnme. Owing to i t s rarity, Yew woodland is listed with priority stat~ts on Aiinex f of the IXJ Hzbitats Direclive.
At Banteer there are a number o f Iiollows in the sediments of the floodplain diere subsidence and subterranean drainage have created isolated wetlands, sunk below the Ievel ofthe surrounding fields. The water rises and falls in these holes depeiiding on thc watertable and several different communities have developed on the acidic OT neutral sediments. Many afthe ponds are ringed about with Grey WilIows, rooted in the mineral soils but sometimes collapsed into the water. Beneath the densest stands are woodland herbs like YelJow Piriipemd (Lysinziruh/7'a: i78/7?OTU??t) with localIy abui:dant Sias~70rt (Cditriche stagpalis) and Marsh Ragwort (,%wecio pdusfris), One of the d.epressions has Silver Birch (Betzilu pendzrlr!), Ash ( F ~ m i m ~ s e.xce.lsior), Crab Apple (MuEus syhest~-is) and a !&le Oak (Quercus r+obz!r) ii? addi'iion to the will.0ws.
