ABOUT THIS APPLICATION FORM

This form is for the purpose of making an application for an Integrated Pollution

Prevention and Control (IPPC) Licence under the Environmental Protection Agency

Acts, 1992 and 2003. There is a separate application form for applicants who wish to

apply for the Pig & Poultry sector.

The Application Form must be completed in accordance with the instructions provided

in the IPPC Licensing Application Guidance Note. The Guidance Note gives an overview

of IPPC Licensing, outlines the licence application process (including number of copies

required) and specifies the information to be submitted in the application. The

Guidance Note and application forms are available to download from the IPPC

Licensing pages of the EPA’s website at www.epa.ie. A valid application for an IPPC

licence must contain the information prescribed in the Environmental Protection

Agency (Licensing) Regulations, 1994 to 2004. Article 10 of the Regulations sets out

the statutory requirements for information to accompany a licence application. The

application form is designed in such a way as to set out these questions in a

structured manner and not necessarily in the order presented in Article 10. In order

to ensure a legally valid application in respect of Article 10 requirements, please

complete the Article 10 Checklist provided in Annex 2.

This Application Form does not purport to be and should not be considered a legal

interpretation of the provisions and requirements of the Environmental Protection

Agency Acts, 1992 and 2003 and the Environmental Protection Agency (Licensing)

Regulations 1994 to 2004. While every effort has been made to ensure the accuracy

of the material contained in the Application Form, the EPA assumes no responsibility

and gives no guarantees, undertakings and warranties concerning the accuracy,

completeness or up-to-date nature of the information provided herein and does not

accept any liability whatsoever arising from any errors or omissions.

Should there be any contradiction between the information requirements set out in

the Application Form and any clarifying explanation contained in the accompanying

Guidance Note, then the requirements in this Application Form shall take precedence.

The change from the existing IPPC licence applied for in this application is tooutfall the cooling water to the River Lung. The existing licence has the cooling wateremission point to the West Drain and all of the monitoring taking place there. Thisapplication does not propose to change the existing situation except to have thetemperature read at the outlall to the River Lung instead of at the emission point to theWest Drain. It is proposed to pipe the West Drain across the Town Stream to the headof the existing open ditch. The purpose of this is to benefit fiom the natural coolingthat will occur in travel along the length of the existing open ditch out to the proposednew discharge point. The temperature of the discharge will nct exceed 27"C.

This application also contains details of the amended route of the final treated effluentoutfall pipe from the WWTP to the River Lung. A 700 mm diameter is used to conve),'storm overflow fiom a County Council site on the edge of Ballaghadereen Town.This pipe intercepts the treated effluent outfall pipe and carries its contents down tothe River Lurrg.

Water loss occurs in the following ways *

- evapotranspiration ( E-T) from vegetation- evaporation from water surfaces / ponds- percolation through the ground- direct outflow via overflow pipe

The water regime is examined for the following periods *

- annual- winter seixon , November to April- sutnmer season . Mav to October

The winter and summer seasons are taken to correspond with similar datain Teagasc work on which most of this hydrology of this report is based.

The flow paths taken by water in the lagoon / wetlands are shown onAttachment 2.

Inflow

The 30 year annual average rainfall at Ballaghaderreen is 1l56mm,comprising 616mm in winter and 543mm in summer. Rainfall figuresfrom the Meteorological Service are shown on Attachment 3.

Annually, about 50Yo of rcinfall runs off the land in Ireland as a whole.This figure is taken as being representative of the lands in question. Theremainder of the rainfall is lost through E-T and percolation to ground.For the lands contributing to runoff, E-T losses are taken as 42Yoannually, and percolation as 87o (Ref. J. Mulqueen, Teagasc).

In order to estimate the variation in runoff with the seasons, it isnecessary to divide the E-T and percolation losses into summer andwinter components. E-T increases in summer, while percolation generallyfalls. The reverse happens in winter. Field studies by Teagasc at a similarlocation in North Connaught have shown that79o/o of total annual E-T

Q : kAi : 14204 m3 / annum approx.

This flow is assumed to be spread evenly throughout the year, due to thesaturated condition of the peat, and the relatively stable hydraulicconditions on the lands. This low percolation flow is consistent with fieldobservations on site throughout the year.

- Direct Discharge

The remainder of the total inflow discharges via the outflow pipe to thefield drain. As shown by the attachments, the irrigation lands are dividedby a bank. Water entering the upper section percolates through the bankand the peaty ground to contribute to surface water in the lower section.A portion also overflows to the lower section through an overflow pipe.Ultimately this water discharges via the overflow pipe to the field drain

A summary of outflow is given in Attachment 4.

The above sections - Overall Water Regime , Inflow and Outflow havebeen taken from the EIS prepared in 1996. The Water Section in this EISis contained in full in Auachment 14.

Quality of the Discharge to the River Lung

Over a considerable number of years , the quality of the discharge fromthe lagoon / wetland to the River Lung has been monitored. The qualityhas shown an improvement over this period , but varies during thesurnmer and winter seasons. The quality during the summer season islower than during the winter season. There is less outflow in summerseason which mitigates the lower quality somewhat. The qualrty variationis principally as result of natural photosynthesis in summer season, withincreased P concentration being carried out. In addition to this , there wasin most years a start up period in the plant wherein the overall effluentquality was variable. This was generally around mid March at the start up

of high volume operations at the plant. It resulted invariably to somediversion of off standard treated effluent to the lagoon area. This wasrecorded in the plant records.

The new IPPC license will require focus on the start up of high volumeoperations to eliminate its impact on effluent quality completely.Coupled with this there were very infrequent off specification dischargeswhich were automatically diverted to the lagoon area. These were alsorecorded in the plant records. The new IPPC license requires offstandardtreated effluent to be eliminated completely.

The quality of the discharge to the River Lung over the last 5 years hasbeen checked monthly. The nutrient content plus the COD weremeasured. The sampling was done on an approximate monthly basis andthe analyses were carried out by Euro Environmental Services , CoLouth. This is given in Attachment 5.

To quantifu this an estimate is carried out for the summer and winterseasons over the last 5 years. This estimate uses the averageconcentrations analysed for those seasons multiplied by the average dailyflow for the specific half year period. This is shown graphically inAttachment 6.

It is clear from the above that the quality of discharge to the River Lunghas improved progressively over the last 5 years. This will continue toimprove with the further reduction and elimination of discharges fromShannonside.

River Lung Quahty

The River Lung qualrty over the last roughly 10 years is shown onAttachmentT and the trends are graphed in Attachment 8. Thisinformation is from EPA data.

The overall quality of the river has improved considerably over the last10 years. It is currently Q index 4 whereas it was Q index 2 some 8 yearsago. This can be attributed to a number of positive changes that havetaken place with regard to the discharges-

- Town of Ballaghdereeen has installed a secondary treatment plant- Shannonside Milk Products have improved their effluent quality- Meat processing factory has stopped processing- Agriculture has limited fertilizer application to land

The River Lung quality downstream of Ballaghaderreen (station 0350)is still slightly less than that upstream ( station 0400).See Attachment 7.The most recent biological assessment showed a Q rating of 4downstream and 4-5 upstream. The current N and P figures are consistentwith those of the River Lung generally at the present. This is apparentfrom results at the upstream station at Figh Bridge ( 0100). The N and Pwill be fuither improved from Shannonside with year around compliancewith the IPPC standards for discharge. This will reflect in the the RiverLung quality and may even bring it to Q index 4-5 atdownstream station0350.

Quality of the Discharge to Groundwater

It is difficult to be exact on the precise quantity of water from thelagoon/wetland areathat ends up as groundwater. John Mulqueen ,Teagasc, in his work already referenced on this , gave an indicative figureof 8Yo of total from lands contributing to runoff.

Trial holes were dug throughout the land and these are shown onAttachment 9. They all showed a dense saturated grey clay at between 1.5and2 m from surface. This dense saturated grey clay is referred to locallyas 'daub'. This clay is highly impervious. This is overlain by dark brownpeat with thin layer of topsoil over.

There is no borehole information for the area available from GSI. Localenquiries from well drillers at locations close to the town ofBallaghadeffeen have wells at between 50 and 200 ft deep. There are noreports of contamination to wells resulting from the lagoon/ wetland area.There was no investigative well sunk in the area for the purpose of thisreport. The indications are clear from the soil type , the presense of the'daub' and from the absence of any reported problems that a well was notrequired. A further difficulty was recognised in that it would be difficultbecause of access to drill a well at the lagoons.

In hydrogeological terms the lagoon/wetland is located on an area of lowvulnerability over a locally important aquifer. See Attachment 11 onAquifer and Attachment 12 on Vulnerability. The low vulnerability to theaquifer classification is due to depth and to coverage type. That therehave been no incidents or repofts of well water contamination resultingfrom the lagoon / wetland is consistent with this low vulnerabilityclassification.

Physical Condition of the Lagoon

The lagoon was constructed in 1995. It is a sound structure. The lagoonwhen originally constructed in 1995 is photographed . The same viewtoday is also photographed showing how the area has matured. Thesephotographs are shown on Attachment 13.

A report on the stability of the lagoon was prepared in 1996. This reportis attached together with some photographs of its original construction.See Attachment 15. The lagoon embankments have been structurallyexamined for stabilify many times since their construction. They havebeen sound.

The lagoon embankments were granted planning permission by the CoCouncil when the factory was constructed in the 1970's. See Attachment16.

Proposed Decommissioning of the Lagoon

The lagoon is currently part of a wetland with much wildlife and birdactivity. Care should be taken to ensure that any decommissioningactivities do not impact this unnecessarily.

The steps required by the IPPC licence will have the effect of notintroducing any additional nutrient or organic matter from the factory tothe lagoon. This will relieve the lagoon of the diversion off standardtreated effluent at the start of the dairy season in mid March. It will alsoeliminate occasional diversion that upset final quality due to shock loadto the treatment plant.

The impact of the discontinuation of the automatic diversion of offstandard treated eflluent will over a relatively short period of time resultin a cleaner discharge to the River Lung. This is particularily the case forsoluble content as it essentially a flushing operation. We would notexpect this period to take more than one year in view of the large volumeof water. This is based on the following figures.

Consequent on the above which is short term , the long term contributionwould be largely attributed to that associated with the settled matter onthe floor of the lagoon. It is not feasible to reliably identiSr itscontribution at this point. It will be more identifiable after the flushingoperation is completed.

Primarily what would be looked at then would be the nutrient content.

The phosphorous content should not be significant on account of it beinglargely soluble which should see it being carried out early.

The nitrogenous content tends to go in and out of solubility more readilywhich leads to it persisting in the outflow over time.

concentrations of nitrogen in the discharge to the River Lung willdecrease somewhat from its present level.

There is no definite benefit to be got from planting reeds or similar on thefloor. This may increase the rate of nutrient uptake but would add thetending and harvesting to be done. It is likely that much of the settledmud that the nutrient is in is under water. This does not lend itself to easeof planting reeds. To dewater would likely upset the natural wetlandsystem that is there.

The BOD will break dor,vn completely in a relatively short period of timewith the microbiological activity in the lagoon. It should approach naturalrunoff background levels within the first year.

Closure

It is sensible not to upset the natural wetland that is there. The nutrientcontent of the wetland can be monitored to the point wherein thedischarge no longer exceeds the natural background of the River Lung.

Removal of the treated effluent infeed to the lagoon will speed up mattersconsiderably. In light of this a period of monitoring by Shannonside withreporting to EPA should be set up.

An initial period of 3 ypprs of above should be carried out with oncemonthly analyses of lNnd orthophosphate. Should the results of sameindicate extending that period then same would be undertaken byShannonside until the area is deemed decommissioned bv EPA.

concentrations of nitrogen in the discharge to the River Lung willdecrease somewhat from its present level.

There is no definite benefit to be got from planting reeds or similar on thefloor. This may increase the rate of nutrient uptake but would add thetending and harvesting to be done. 1t is likely that much of the settledmud that the nutrient is in is under water. This does not lend itself to easeof planting reeds. To dewater would likely upset the natural wetlandsystem that is there.

The BOD will break down completely in a relatively short period of timewith the microbiological activity in the lagoon. It should approach naturalrunoff background levels within the first year.

SOILS OF FI-/IT TO UNDULATING LOWLAND I 13

The principal soil within the association consists of a moderately well drained Crey BrownPodzolic of loam to clay loam texture and of medium to high base status. The profile is characterisedby a slightly plastic consistency and weak structure which becomes massive in the lower part of the Bhonzon at about 65 cm. Clay and silt contents in the surface horizon are about 25%o and 30Yorespectively but the clay content increases to over 30Yoin the B horizon.

The principal soil gives way very quickly to a less well-drained soil in the flatter areas, whichcomprise about25oh of the association. (This soil has been mapped as Association 40 where it occursextensively). This associated soil has a clay loam surface horizon and a clay loam to silty clay loamBtg horizon with silt content in the B horizon generally greater than 40%o.lt usually has a very highbase status. Some gravelly Brown Earths and minimal Grey Brown Podzolics are also present inplaces to a small extent in this association. These latter soils are found generally on kames, crests ofhillocks and terraces. They are mostly formed from fluvioglacial material. Surface texture is sandyloam to loam, and the soils are moderately shallow with rapid permeability.

SuitabilityThe principal soil has a moderately wide use range. It is suitable for grassland but is also used fortillage, including intensive production of vegetables for the Dublin market. The soil is not ideal fortillage because of its heavy texture, weak structure and sticky consistency but, because it occurs in anarea oflow rainfall, it can be successfully used for these purposes. In grassland, poaching by livestockcan be a problem in spring and autumn but this can be overcome by good grassland management.

The more poorly drained associated Gley (25%) presents greater problems for tillage and hasto be worked when moisture conditions are optimum.

The use range of the associated Brown Earths and Grey Brown Podzolics is moderately goodbut restricted somewhat by slope, shallowness and drought. Due to scale limitation these latter soilsare not shown separately on the soil map.

ASSOCIATION 39:

GLEYS 9070, GREY BROWN PODZOLICS 10%

The soils of this association occupy 3.45% of the country (583,630 ac.; 236,192 ha.). They occurwidely throughout the limestone till areas of the country where they occupy the more lowlyingpositions. The principal soil is a poorly drained Gley of clay loam to clay texture and of high basestatus. It is found mainly in Lirnerick, Roscommon, Galway, Tipperary, Laois, Kilkenny, Kildare.Cork and other counties to a more limited extent. In many places. however, it is not possible to showit separately on the map because of its occurrence in small enclaves. But it constitutes the mainassociated soil in Associations 3l and 34 especially.

The profile is characterised by a thick, strongly gleyed textural B horizon which merges withthe parent material at approximately 150 cm depth. Clay content is high, ranging from about 40/o inthe surface to almost 50%:o in the parent material, while silt contents range from about 30% in thesurface to 40o/o in the oarent material.

EXPLANATORY BULLETIN TO SOIL MAP OF IREI-4ND I98O\ ; i

Plate l7: The heavy-textured Gley soils of Association 39 hwe a serious drainage problem.

Structure is weak in the upper horizons and becomes massive with depth; only tlre upper horizons arefriable. The poor drainage is caused by the heavy texture and by the slow run-off due to the relietwhich is aggravated by the poor perrneability of the soils themselves.

Plate 17: nle heavy-textured Gley soils ofAssociation 39 have a serious drainage problem.

Structure is weak in the upper horizons and becomes massive with depth; only the upper horizons arefriable. The poor drainage is caused by the heavy texture and by the slow run-off due to the relief.which is aggravated by the poor permeability orthe soils themselves.

In Laois, where this soil is relatively extensive (Mountmellick, Ponlaoise, Mountralh area),there is a strong inOuence of sandstone in the parent material and the entire profile is more sandy(organic sandy loam). The well-drained associated soil in this area is similar to the principal soil ofAssociation 36 which occurs immediately to the east.

SuitabilityBecause of their poor drainage, these soils have a limited use range and are suited mainly to pasture.Susceptibility to poaching is a problem and good management is necessal)' to sustain maximumproduction. lfa suitable outfall can be obtained they can be successfully drained.

The River Lung rises in low hills west of Ballaghaderreen Co. Roscommon. and

follou's an east-south-east course until just south of Ballaghaderreen when it turns

north-west to flou' into the southern basin of Lough Gara. Perhaps because of it's

fairly flat profile. the Lung is a fairll' sluggish river especialh, in summer Previouslr,

the lower reaches around Ballaghaderreen were particularly prone to very extensive

land flooding As a consequence. the OPW instituted an arterial drainage scheme

about to alleviate the floodinq. The scheme began about l4 vears ago at the discharge

to Lough Gara and since then has progressed up the channel lt rvas completed in

The nutrient chemistry results would suggest that the catchment of the Lung is not

intensively farmed as the nitrate (oxidised nitrogen), phosphate (MRP) and ammonia

levels were relatively low at Banada Bridge which is upstream of all the main point-

source discharges to the river. More recently these same parameters were again

measured at both Float and Banada Bridges on l3 occasions between August I4th and

November 17 1994 producing generally similar median results (Table 2)

Table 2 Median concentrations of key u,ater quality parameters measured onthe Lung fuver on l3 dates between 2418/94 and 17 ll l/94 b1, the EPA(Kilmartin 1995)

Water Oualiry,

Water analysis results from the present study carried out on October 20th (Sites 53 &

54, Table 6) indicate that the overflow from the inigation area is rich in phosphorus

and ammonia and very high in chlorophyll. The latter presumably builds up during the

summer in the ponded area due to run-off of nutrients from the irrigated sludge. The

latter also accounts for the relatively high BOD values measured at 53 the overflou'

from the lagoon and at 54 the outlet drain to the fuver Lung. This BOD was derived

in all probabilitl, fvsm the high phgoplankton respiration rather than the presence or

organic waste per se. High conductivity is consistent with elevated chloride.

hydraulic 10<lding frolll 2~Om~/day to 60m3/day is unlikely in itself to have all\' affect

on the ri .....er However. the change from an open inigalion system which drained

directly to the river 10 one now which is relained behind an embankment is likelv to

significanll\' reduce the inpul of phosphorus panicularly in the form of organic solids

during 10 Ihe River Lung The improvement is most likely 10 be apparenl during the

weller montl1s when II IS most hkel~' lhal in the pasl run-off from the irrigallon area

Improvcmcnl However, given that the relative conlribution, is estimated on average

not to e:-.:ceed 25 - 3% of the total-P load from the Lung (calculated at Float Bridge),

the irrigation area load i~ llOI e,\pecled to cause significant measurable deterioration in

the quality of the river Over time it is likely that phosphorus rich sludge will graduall~

build-up in the lagoon area which may in tum give risc to the release of phosphate

If no change is made to the current irrigation regime, i.e. if 2300m3 of sludge

continues to be pumped to the irrigation fields, it would be expected to have no

additional impact over and above that described above for the proposed regime. This

assessment is based on the fact that there will be very little difference in the total

sludge solids applied to the irrigation area in either regime and that the

hydraulics/hydrologl, of the svstem is qoverned by precipitation rather than the

hydraulic load from the irrigation sprayers.

Recommendat ions

Re-zular re-location of irrisation sprayers within the irrigation areas might help to

immobil ise more sludge in the soil layers of the drier parts of the lagoon thus reducing

the amount of run-off to the lagoon or ponded areas and thence to the river Gven

that there is a possibi l i t l ' of a gradual increase in total P- levels in the overf lou, water

fronr the irr igation area u' i th t ime due to internal loading. reqular nronitorins of both

flou,s and phosphorus levels in the outf lou, \\ 'ater would be adr, ' isable

If no change is made to the curren! irrigation regime. I.e. if 2300m3 of sludge

additional impact over and above that described above for the proposed regime. This

Recommendations

Regular re-Iocation of irrigation sprayers within tne irrigation areas might help to

REPORT ON STABiLITY

i . INTRODUCTION

1.1 The effluent treatment plant at ShannonSlde Co-Op produces

waste sludges, which are disposed of, in part, to

irr1gation lands located north of the factory.

1.2 The irrigation lands have a low earthen embankment around

the perimeter to prevent direct surface run-off into the

River Lung. Some localized ponding occurs behind the

embankment at the eastern end of the lands.

'.3 This report examines the stability of the embankment at

the perimeter of the irrigation lands.

2. EMBANKMENT CONSTRUCTION

2.1 The 1rrigation lands are shown on the attached Key Plan.

The area is low lying, and alongside the R\ver Lung. The

lands are prone to flOOding during periods of heavy

rainfall in winter.

2.2 The perimeter embankment was constructed in 1995, and 15

generally low in profile. The exception is at the eastern

end of the lands, where Lhe bank rises to a maximum height

of 1.5m. The centre berm width is 3.0m and the level of

the crest 1S uniform at lO.6m approx. The sideslopes of

the bank are 50°. Cross-sections bank at the eastern end

are attached; these are taken at the locations shown on

the Key Plan.

2.3 The top water level in the pond is governed by overflow

pipes. Three 100mm diam overflows are at lO.2m invert

level, approximately; a further 1 no. 150mm diam pipe 1S

at 69.9m invert level) approximately. In normal circum

stances the water level lies at 69.9m. During heavy

rainfal), the level can rise temporarily, to a maximum of

lO.3m.

2.4 As c result of the disturbance of the soil during

construction, there is extensive vegetation on the bank,

pr1ncipally chickweeds, nettles. grasses and thistles.

3. MATERIAL

3.1 Trial hole logs are attached, as recorded at the locations

shown on the Key Plan. Grey clay, with some gravel and

cobbles, lies on average 1.5m below surface level 1n the

area in question and extends to depth. The clay is

overlain by oxidised unconsolidated peat and 300mm of

topsoil. The bank is constructed of mixed peat and clay.

3.2 The permeability of the peat is estimated at 5.0 x 10- 5

mis, which 1S representative of such material. The grey

clay has a significantly lower permeability at an

estimated 5.0 x 10- 8 m/s.

4. FLOW NET ANALYSIS

4.1 The most critical section of the embankment, with regard

to stability, is Section No.2. The height of the bank is

greatest at this point, at 1.Sm. A flow net analysis was

carried out for this section, and 1S attached. The

calculation reference is attached as an Appendix.

4.2 The clay layer 1S assumed impermeable for the analysis,

which is reasonable, given the significant difference in

the permeability of the peat and the clay.

4.3 The permeability is assumed to be constant and lsotropic

1n the bank and the undisturbed material. This 1S

reasonable given the shallow depth of the peat, and the

fact that peat was used to construct the bank.

4.4 The maximum water level of 70.3m is used for the

analysis. In practice, the level rarely rises above

69.9m. Therefore, this assumption gives a conservative

result.

4.5 The water table 1S assumed to 11e at surface level on the

downstream side of the bank. In practice, it may lie

300mm or more below ground level. This assumption also

gives a conservative result.

4.6 The

parameters are estimated at c = 0.5 te/m 2 and

4.7 The flow net indicates that the theoretical phreatic

surface intersects the downstream face of the bank, to

give a seepage surface about 250mm long.

5. EXAMINATION OF FAILURE MODES

5.1 There are three failure modes to be considered 1n relation

to earthen dams.

1. "Piping" and uplift due to seepage pressure.

2. "Sl oughi ng" due to eros) on of the seepage surface.

3. Instab,lity due to slippage.

These modes are examined at the critical section.

5.2 Piping and Uplift

Piping refers to the accelerating development of

preferentia1 flowpaths through an embankment, leading to

erosion of the soil, and embankment failure. The critical

location 1n considering piping is at the toe of the

embankment. It can occur when the flow net intercepts the

downstream face of an embankment. 'Quick' action can also

occur immediately outside the toe, due to the pressure of

ris1ng water overcoming the soil's self-weight.

sect,on of the embankment. the

toe material adequately resists the

exerted by the theoretical seepage

as outlined in the Flow Net Analysis.

At the critical

self-weight of the

uplift pressures

through the banks,

Some trickl,ng has been observed at the toe of the bank ln

the vicinity of Sections 2 and 3. However, this is minor

ln extent, and could be expected given the nature of the

material In the bank. A1so the dense vegetation on the

banks increases the soil stability and absorbs water from

the bank.

5.3 Sloughing

Embankment "sloughing" occurs due to overtopping of a bank

or to high seepage flow rates at the toe of the bank.

Overtopping is prevented by the overflow pipes. The water

level typically lies at 69.9m, and rises only temporarily

during heavy rainfall, to lO.3m max. Therefore

overtopping 15 not likely. Regarding seepage, visual

inspection at the toe of the external banks showed only

minor seepage emerging. Again the dense vegetation acts

to increase the resistance to soil erosion.

5.4 Slippage

The attached Slip Circle Analyses were carried out to

assess the stability of the critical section against

slipping. The section was evaluated at both the upstream

and downstream sides. The analyses indicated factors of

safety greater than 1, implY1ng stable conditions. This

conclusion is supported by field observations, in that no

evidence of slippage cracks was to be seen.

6. CONCLUSION

6.1 The embankment at the perimeter of the ShannonSlde

irrigation lands is built to controlled profiles and

levels, and 1S dense1y covered with vegetation. Field

observations indicate that the bank is stable. No

evidence of sloughing, slipping or uplift was observed.

The observed triCkllng at the toe of the bank at the

eastern end is not structurally significant.

The relationship of Ao to (a = Aa) found by sketching

Sketchiifthe flow net n'ill give successive eorrections to the assumed curve until al-itbe florv and boundrry conditions are met.

Falkovich [33] presents a solution for a in terms of the flow q and theangle p when the upstream face is far from the discharge slope and no tailwater is present. Although the paper does not say so, pr"r.r-"bly the inten-tion is to com.:ute g approximately by meens of Eq. (1.+7).

Solutions for the free-surface florv ijne are given in the literat,ure for otherctses of f lorv. e.g., to a rvell. to a s1'stem of drains in the soil, to or from ariver or cr.nal, etc. i21, 31, 36]. By the use of these soiutions, an approximatedetermination of the free-sunace line cen usuall-"- be made in given condi_tions, end this cen be repeatedly improved as the florv net sketching pro-ceeds under the prevail ing boundary conciirions.

The limitations on the use of sketching as a solution technique havealready been pointed out. It is norv eppropriate to consider other methodsof deeling rvith the problem.

In the present probl.* of-flowin porous media, the flow is undoubtedly rotationai on the ,oi.ror.opic scale,but irrotational from the overe.li vierv. These other physicai situations maynow be considered from the point of vierv of obtaining solutions to seep&geproblems.

top flow line, draw the "basic parabob tI given by Eq. (+--15) using point Dof fig. -!-lO(a) :l.S the focus and the value of S from Eq. (+---16a). The distance between the point of intersection of the parabola and the downstre:lmslope of the daro J 0 and the discharge point J me~ured along the slope istermed .6a. The relationship of ~a to (a -+- .6a) found by sketching flownets for a number of different angles {3 is plotted on a graph (Fig. 4-12).The basic par:lbola is then altered to curve smoothJy into the dischargepoint obtained by stepping off the disb.nce 6a from the point J o. Sketchingthe flow net will give successive corrections to the assumed curve until allthe fio\l..· and boundary conditions :lTe met.

FaLkovlch [:331 presents a solution for a in terms of the flow q and theangle f3 when the upstream face is far from the discharge slope and no tailwater is present. Although the paper does not say so, presumably the intention is to COIl'Jute q approximately by me3.ns of Eq. (-!--!7).

Solutions for the free-surface flow line :ue given in the uterature ior otherC.1.Ses of flow. e.g., to a well. to a system of drains in the soil, to or from ariver or canal. etc. [21, 31, 36]. By the use of these solution~, an appro;-,.irnatedetermination 01 the free-surface tine c~n usually be made in given conditions, J.nd this c:m be repeatedly impro\."ed ~ the flow net sketching proceeds under the prevailing boundary conci cions.

The lirn.jtations on the use of sketching as a solution technique havealready been pointed out. It is now :l.ppropriate to consider other methodsof de.3.1ing \\.j t.h t.he problem.

4-4 Electrical analogy. The 3.nalogy between fluid, thermal and electric:llflows has been men boned before. The Laplacian equatlon also descri besthe magnetic field about a magnet, the displacement of a rubber membraneperpendicular to its pbne (the displacement is not necessarily small [10]),:l.nd the inotational potential flow of fluid. In the present problem of flowin porous media, the flow is undoubtedly rotational on the microscopic scale,but irrotational from the overall view. These other physical situatiorlS maynow be considered from the point of view of obtaining solutions to seepageproblems.

REQUIREMENT NO.4: The developers shall submit,for the approval of the Planning Aurhority,detailed plans and proposals for the disposalof process water and washings from the factoryby spray irrigation over land. The detailedproposals shall show, by means of detaileddrawings, maps and specifications, theboundaries of the lands and areas over whicheffluents are to be spray irrigated; layoutand of pump-houses; holding tanks; pipe linesand spray apparatus and methods of operation.The developers shall be responsible for ensuring that the irrigated effluents shall percolateonly through the soil of the irrigation areasand that the irrigated effluents shall not fallupon, or enter any drain or watercoursedischarging to the Lung River.The developers shall, for this purpose, sealoff all existing drains within the boundariesof the irrigation area to prevent dischargesto the Lung River or other water-coursesdischarging into the Lung River.The developers shall construct and maintainproper embankments around tile lrrig3tion areato prevent surface run-off to water-coursesoutside the irrigated areas. The sub-soildrains to be provided by the developers shallbe so laidout and constructed that the discharges from these draIns shall be collectedto a sinale point. before dlscharge to thereceiving water, glven with the consent,1n writing, of the Planning Authority. Aninspection chamber shall be bUllt on theoutlet drain to the receIving water or toenable the taking of samples.

1. Introduction

AQUAFACT International Services Ltd. was commissioned by Mescal and Associates

consulting engineers to carry out a macroinvertebrate assessment on a drainage ditch

situated next to Connacht Gold’s Shannonside dairy processing plant. It is intended to

discharge warm waste water from the plant into this ditch and the Environmental

Protection Agency (EPA) requested that the area be surveyed prior to this.

The drainage ditch in question is situated at the co-ordinates: 53°54’01.39”N

08°33’46.94”W

The ditch was constructed approximately twenty years ago and its purpose was to

collect run off from adjacent stand by sprat irrigation area to ensure that excess nutrients

would not be introduced to the town stream which runs parallel to the ditch. The ditch

runs parallel to the River Lung and joins the river approximately 650 m east of the dairy

processing plant.

AQUAFACT undertook a freshwater biological assessment to discover the species of

macroinvertebrates present and to determine the effect that the waste water will have on

the ditch habitat. A two minute kick sample effort was made on three pre-determined

sites.

2. Methodology

2.1 Kick sampling method

Three sites were selected along the drainage ditch, These can be seen in Figure 1. A

standard pond net (mesh size 500µm) was used to retrieve the samples. Generally it

is best to choose riffled sections of a stream to sample using the kick sampling

method as these tend to contain a larger diversity of pollution sensitive fauna due to

the higher oxygen content. Normally the net is pointed towards the flow of the stream

and the sampler disturbs the stream bed with their foot up to a meter upstream from

the net, dislodging any macroinvertebrates in that area. The sampler moves

diagonally across the stream doing this until two minutes have elapsed. However at

this site there was either very little or no flow in the drainage ditch; therefore, sites

were selected as close to the predetermined areas as possible and the samples

were taken by actively sweeping the net through the weeds. The sampling time had

to be reduced from two minutes to one minute per site as the amount of mud on the

stream bottom meant that the nets filled rapidly and were no longer able to sample

effectively.

When sampling was complete, the contents of the net was washed and transferred

to a container. These were then brought back to the lab, washed through a 1mm

mesh and preserved in formalin.

2.2 The biological river quality classification system (Q-

Scheme)

The Q-Scheme has been in use in Ireland since 1971. It has undergone a number of

modifications since then and has been included in the Local Government (Water

Pollution) Act, 1977 (Water Quality Standards for Phosphorus) Regulations 1998.

This assessment is routinely carried out by the EPA. The Q-Scheme divides benthic

macroinvertebrates up into five indicator groups according to their tolerance of

pollution, particularly organic pollution. Depending on the groups numerical

distribution in a sample, the overall quality of a water body can be determined.

The samples obtained at the Shannonside drainage ditch were returned to Aquafact

and analysed by a skilled freshwater biologist down to family/genus where possible

with the aid of a stereoscopic microscope, forceps and the relevant keys (see

references).

In order to determine the biological quality of a stream, the analyst must assign a Q-

index to each sample using the macroinvertebrates present. The Q-index is a quality

measurement for freshwater bodies that ranges from Q1 – Q5 with Q1 being the

poorest quality and Q5 being pristine/unpolluted (See Table 1)

Table 1: Relationship between biotic index and water quality

Biotic Index Quality Status Quality

Q5, 4-5, 4 Unpolluted Class A

2.3 Effluent and Temperature

The EPA’s handbook entitled “Parameters for Water Quality: Interpretations and

standards” (2001) lays down guidelines and highlights limitations which are placed

on effluents which are discharged into a natural aquatic environment.

This handbook also addresses the issue of water temperature in effluents. It states

that the temperature of the effluent must not exceed the unaffected waters (in this

case the River Lung) by more than 1.5°C and must not be above 21.5°C during the

period of 1st of November and 30

th of April, where species which need colder water

for reproduction are present.

The species of fish occurring in the River Lung include brown trout (Salmo trutta), eel

(Anguilla anguilla), pike (Esox lucius), bream (Abramis brama), roach (Rutilus

rutilus), tench (Tinca tinca), rudd (Scardinius erythrophthalmus), carp (Cyprinus

carpio) and perch (Perca fluviatilis) (URL 1). Of these only pike spawn between

November and April and need a water temperature of 8°C.

Figure 5: Photograph of St. 3. Lemna sp. can be seen at either side of the stream.

The photographs above show the three sections of the ditch which were sampled. At the

time of the survey the ditch was frozen over and ice had to be broken before a sample

could be taken. More photographs of the survey area can be found in APPENDIX II.

The stream bottom at all three sites was composed of anoxic muds and methane gas

was released from the sediment of St. 1 upon disturbance. High numbers of Tubifex sp.

and Lumbriculus variegatus indicate an area which has been severely depleted in

oxygen. Large amounts of duckweed (Lemna sp.) were documented growing on the

surface of the sites.

The ditch is ca 650 m long, ca.1.5 m wide and 1.25 m deep on average. This gives a

volume of ca 1,200 m³ and the proposed volume of warm water is 6,000 m³ per day or

ca 70 l per second.

4. Conclusions

The results of the kick sampling effort performed by AQUAFACT showed that the

drainage ditch adjacent to the Shannonside dairy processing plant suffered from

moderate pollution and scored a Q-index value of Q2-3 for all three sites sampled.

The area is low in oxygen as indicated by the abundance of Tubifex sp. and Lumbriculus

variegatus in the samples and the present of H2- rich anoxic sediments. Other

macroinvertebrate species present there in significant numbers included Asellus

aquaticus and Chironomus sp. as well as various molluscs such as Aplexa hypnorum,

Anisus vortex and Planorbis planorbis. All of these species are indicative of a poor

habitat. In a healthy water body at this time of year, samples should be yielding high

numbers of pollution sensitive species such as stoneflies and mayflies.

The introduction of warm water into this environment would mean that less oxygen

would be dissolved into the water. However, as the species present are ones which

thrive in polluted, low oxygen habitats this would not have any significant effects on

populations here.

If a significant effect was experienced by the macroinvertebrates in this habitat due to

the introduction of warm effluent water it would be considered acceptable as the original

purpose of the drainage ditch was to mediate the effects of pollution from the nearby

stand by spray irrigation area. The macroinvertebrate species present are both

widespread and common and their loss would not be significant as they are well

represented elsewhere. The drainage ditch should be treated as a buffer zone in this

respect and used as an area in which the effluent water can cool to acceptable levels

before being introduced to the River Lung system.

It is important however that the effluent discharged from the ditch to the River Lung does

not affect the river itself. The river is currently regarded as “at risk of not achieving good

status” in regards to the Water Framework Directive (URL 2) and any element which

could further jeopardise the rivers status should be avoided. This may require that the

CONNACHT GOLD – DISCHARGE TEMPERATURE

HEAT DISCHARGED

The following summarizes the position with regard to heated discharges from the

plant.

The process effluent from the plant gravitates from discharges throughout the plant to

the process sewer system. This, in turn, discharges to the WWTP. The heat contained

in the process sewerage dissipates in passing through the WWTP. The WWTP has a

retention period of several days. The treated effluent coming out of the WWTP is

below the licence limit of 25°C.

Heated process effluent discharging to the process sewer is largely limited to plant,

lines and tanker washings. It is not very significant in terms of the total heat load

discharged from the plant.

The bulk of the heat load results from condensate discharge and from cooling water

discharge. The condensate discharged to storm drain is that portion of the water

evaporated off the milk. Approximately 90% of milk is water. The evaporation is

done in what are referred to as ‘effects’. As milk is evaporated, the condensate from

the first effects are sent to the boiler for makeup water , the condensate from the

middle effects are discharged to surface water drain and the condensate from the later

effects can be directed to the process effluent if high conductivity is automatically

detected. The above very briefly summarizes the evaporation at Connacht Gold and

the process is similar to other dairy plants throughout Ireland and overseas.

The cooling water is used throughout for plant cooling. This cooling water is non

contact with the milk being processed. There is a large range of equipment throughout

using cooling water.

The cooling water and a large portion of the condensate are discharged to the surface

water drainage system. At Connacht Gold this gravitates to the ‘West Drain’. Most of

the heat to surface water drain is contained in these streams. This was confirmed in a

study carried on site a number of years ago at the plant.

The plant was examined again in 2009 to check for potential areas where the heat

being currently discharged from the plant could be reused economically in the plant.

This was investigated to identify any practical heat recovery that could be carried out

in the plant. The following areas were examined and a summary of the examinations

is as follows:

BOILER

The boiler is oil fired. It has capacity of 36,300 kg / hr steam. See attached Fig 4.

To make this steam it uses 0.52 kg water / kg steam. The maximum hourly

requirement is thus 18.8 m3/hr of water.

Part of this is provided as steam condensate return and addition of necessary softened

water from the mains supply.

The remaining part would typically be up to 10 m3/hr of water. This is supplied by

returning part of the total 50 m3/h condensate to the boiler.

It is done by directing the condensate from the evaporator area across to the

condensate tank located in the Service Area.

HOT WATER USE AND DISCHARGE IN THE PLANT

Throughout the plant warmed water is provided by locally controlled steam addition

to cold water for temperature control. There is neither storage, nor a separate water

supply system, for heated water. To use up excess heat contained in the hot discharge

it would be necessary to provide both storage and a separate water supply system. The

majority of the applications for hot water would further not be suited to direct use of

condensate for hygiene reasons. This would necessitate using heat exchange to

additional cold water supplied.

All cleaning hot water discharges, whether they are CIP controlled or manually hose

operated, go to the process drains. The heat is necessary to meet the various cleaning

requirements. The quantities of process effluent discharged from the individual

process areas throughout the plant are shown on Fig 5/1. This work was carried out in

the mid nineties. The quantities discharged are reduced since then and there are some

process alterations that would change this but not to a significant degree. It is shown

here to give the reader a good idea of where water is discharged to the process drain.

It does not indicate anything regarding the effluent temperature. It should be noted

that the heat load in the process effluent does not give difficulty at the final discharge

where the limit is 25°C. Consequently heat is not of significance in the process

effluent.

Heat can be of significance in the SW2 discharge. The bulk of this heat arises from

the milk evaporation and comes from the plant in the form of hot condensate and

heated cooling water. Other plant discharges to SW2 are present but are small in

terms of heat loss relative to the condensate and cooling water.

OVERVIEW OF REUSE OF HEAT IN COOLING WATER AND CONDENSATE

DISCHARGES

It should be noted initially that this heat is unavoidable. An essential part of the

evaporation process is boiling off water from skimmed milk and condensing the

vapours in preheating incoming skim. This use of boiled off water to heat up skim

feed together with the increased pressure of operation results in condensate coming

off at the order of 50°C. In addition the entire processing operation requires a large

amount of high energy pumping. This requires a constant high flow of cooling water

to the system. This cooling water is pumped to the process area. There it takes up the

heat from various operations, particularly the evaporators, and is discharged to drain

at elevated temperature. This water is not in direct contact with the skim milk. It is

however much less useful in considering heat return as its temperature is considerably

lower than the condensate.

A number of potential areas in the plant for reuse of the heated water were considered.

This concluded that the only areas of viability were the lorry wash and the casein

plant. These two are referred to in some detail in the next section. Domestic water

heating and space heating for the office and reception areas was also considered.

These were less attractive in terms of capital recovery. They are also referred to later.

The in automated plant CIP (clean in place) washings throughout generally use 80°C

water. This is considerably warmer than the condensate and cooling water which

would make for very complex hot water supply to incorporate them. The condensate

is warmer but still well below 80°C. More importantly the condensate could not be

used for final CIP of plant items. There would also be considerable concern for

hygiene reasons in using the cooling water. In terms of the quantity , the volumes of

heated water used in the CIP of the various plants is only a fraction of the condensate

and cooling water quantity discharged from the plant. This is evident from the

discharged quantities shown on Figure 5/1. Overall the use of condensate as hot

water to CIP would be limited and the use of cooling water would not be hygienically

acceptable.

POTENTIAL REUSE AREAS

Lorry Wash Area for External Hot Water Hosing

Condensate could be used for external washing in this area. Typically the total volume

of heated water used for external washing here is approximately 50 m3/d in season.

This is at approximately 70°C. This water could be supplied via the Condensate

Tanks on the Service Area side. It would be necessary to provide a smaller washing

tank complete with automated steam addition to raise the temperature. This then

would be fed with a new line from the Condensate Tanks on the Service Area side

with suction out to power hose side.

The use of condensate would be approximately 50 m3/d.

The saving in heated water is approximately 50 m3/d x 30°C = 5.4 mBTU /d

@ 3412 BTU / kWh gives 1582 kWh @ 3.9 c / kWh gives €61 /d.

for 150 days gives € 9150 / y saved on fuel cost.

The cost of providing the facility is as follows:

Extension of steam lines and controls of local temperature 5

Tank 50 m3 complete with insulation and safety facilities 15

Condensate feed line from existing Condensate Tank at Service Area 3

Discharge hosing arrangement and control 2

Miscellaneous 5

---

€30 K

The above would reduce daily heat to drain by less than 5% and the return period for

the investment is 3.3 years.

Separate Washwater Supply at the Casein Plant

When in use the Casein Plant uses up to approximately 70 m3 /d of floor washwater.

This is typically at 70°C. A local separate tank could be provided which would take

condensate, subject to hygiene conditions. . Assume that whatever it takes can

increase temperature by 30°C. It would be necessary to provide an insulated water

tank with automated steam addition to heat to 70°C. This would then be fed with a

new line from the evaporator area for the reused hot water which would entail

pumping. The discharge side of the new tank would be to power hose.

The daily heat reused calculates at 7.6 m BTU’s which saves €85 /d.

The Casein plant over the last number of years has run for approximately 80 days on

average in the year. The long investment return period in this case is due to the

current low market for casein which results in a much reduced no of days of operation

The annual saving would be €4250 /y.

The cost of providing the facility would be some €15K more than that outlined for the

Lorry Wash facility because of the additional on the transfer of the Condensate or the

cooling water from the evaporation area and because of the larger tank. Thus the cost

would be €45K.

The above would reduce daily heat to drain by less than 5% and the return period for

the investment is 10.6 years.

Office and Reception Building Heating

Consideration could be given to providing a heating system complete with internal

radiators throughout both the office and the reception building.

This would use the Condensate as it is at the highest temperature. The condensate

taken at 50 to 60°C is not sufficiently high for use in conventional hot water radiator

heating. It would be necessary to augment the heat prior to circulation and to

incorporate this into new heating systems.

Both of the above are single storey structures. The office which is the front part of the

original structure was built some 35 years ago is some 350 m2. The Reception

Building is recent and is some 200 m2. Approximation of the total heating required

based on 4.5 BTU’s / ft3 is 100 kW. This requirement would be readily provided by

the condensate.

This work would entail transfer pipework for the condensate to the 2 areas together

with integration to the existing systems complete with control. The work would also

entail tying in the existing hot water source to give adequate elevated temperature to

the hot water circulated in the existing system to function properly in heating the

existing space. In addition the supply of condensate to the system is only available in

the processing period of the year and the 18 hr in 24 hr availability of the condensate

would have to be accommodated. A very approximate estimate for this work complete

is €70K.

Assuming some 75 of the 100 kW requirements can be met using the condensate this

would reduce the use of the existing source. Based on the existing source as steam

from the boiler the annual cost saving is calculated as follows:

75 kW x 4000 hrs/y = 337,500 kWh @ 3.9c /kWh = €13,200.

The above would reduce the overall heat to drain by less than 5% and the return

period for the investment is 5.3 years.

DISCHARGE TO SW2

Additional Cooling Used

Currently when the plant is in operation it needs to utilize its full volume of cooling

water complete to maintain adequate discharge temperature. The pumping of this

additional cooling water has significant cost.

Cooling Tower

Provision of a cooling tower on the discharge to the West Drain was considered on a

number of occasions.

The cooling tower location considered was at the head of the West Drain.

This work would entail considerable civil and plant work together with new high

volume pumps and fans.

The cost would be the order of €100 to €150K.

.

The energy use in running this cooling tower would be approximately 25 kW for the

submersible pumps feeding and for internal fans in the towers.

This would amount to an annual cost of 25 kW x 4000 hrs /y x € 0.15 kWh =

€15,000/y.

There would be no financial return for this investment.

Coupled with this there would constant tonal noise and very markedly increased water

vapour emission from this part of the site.

Long Outfall via Backfield

Modification to the existing outfall pipework can be carried out. This will enable the

drainage pipe currently taking the West Stream route to be brought across the Town

Stream to the former irrigation field. The existing 0.7 km long open drain around the

side of the former irrigation area will be used to allow maximum natural cooling to

the discharge prior to outfall to the Lung. The discharge temperature will satisfy the

licence requirement.

Attached is Dwg No 0902/0 ‘Cooling Water Outfall Detail’ showing the new

pipework and the Town stream crossing.

Attached also is Dwg No 0903/0 ‘Outfall - Overall Site Plan’ showing the Western

Drain complete out to the River Lung.

The cost of doing this is limited to pipework cost and there is no pumping or other

ongoing costs associated with it.

The EPA has requested a study of the condition of this drain to be carried out.

SUMMARY

Heat required is provided to the plant from the oil fired steam boiler.

The steam is piped to the various points of use within the plant.

The application of the steam is automated throughout the process plant.

The return of hot condensate to the boiler is already being done. It has a limited

impact only on the heat lost to drain. This is because the quantity of water that the

boiler takes in is small.

There are 3 other areas wherein the reuse of hot discharge is assessed. They are as

follows with their investment return periods:

- Lorry Wash …. €30K @ 3.3 yrs return

- Casein Plant …..€45K @ 10.6 yrs return

- Office Heating ..€75K @ 5.3 yrs return

At present the discharge temperature is maintained by additional water pumping.

Provision of a Cooling Tower would cost €100 to €150K with annual expenditure

€15K.

There would be no financial return from a cooling tower.

Take the drainage in the Western Stream across the Town Stream by gravity and

discharge it to the 0.7 km open outfall drain to cool on its passage to the River Lung.

This has no continuous cost associated with it and is thus the most economical way to

satisfactorily meet the discharge temperature requirements.
