Response to question 4. Chemical Monitoring of the River Finn in accordance

with SI 293 of 1988 shows the river quality to be generally in compliance with

this regulation with only a small number of minor non-compliances noted over

the period 2008-2010.

Question 5 –. Carry out Asslimitative capacitity calculations for the Primary

discharge to the River Finn 95%ile flow shall be used to calculate the

capacioty of the receiving waters for BOD, Ammonia and MRP.

Response - WAC = (Qmax – Qback)(Q95)(86.4),

WAC= waste Assimilative capacity

Qmax= maximum allowable BOD, Ammonia and MPR in the receiving water.

Qback= background BOD in the receiving water,mg/l

Q95 = flow exceeded 95% of the time m3/sec

86.4 = factor to convert to kg/day.

BOD(mg/l) (BOD standard based on the draft surface regs 2008)

Qmax = 2.6mg/l

Qback = 0.85mg/l

Q95 = 0.94m3/sec

WAC = (2.6-0.85)(0.94)(86.4)= 142.12kgBOD/day 142,123g/day

Maximum strength of BOD that could be discharged from WWTP with a WAC

of 142.12kg/day=

142.12x1,000(conversion factor)/225m3/day(dry weather flow) = 631mg/l

Conversion factor 1kg/m3x1,000 = Mg/l

Ammonia mg/l NH3 as N (NH3 standard based on the Draft Surface water

Regs 2008)

Qmax = 0.140mg/l

Qback = 0.055mg/l

PROCEDURES

The procedure for making and processing of applications for waste water

discharge licences, and for the processing of reviews of such licences, appear in

the Waste Water Discharge (Authorisation) Regulations, 2007 (S.I. No. 684 of

2007) and is summarised below. The application fees that shall accompany an

application are listed in the Third Schedule to the Regulations.

Prior to submitting an application the applicant must publish in a newspaper

circulating in the area, and erect at the point nearest to the waste water

treatment plant concerned or, if no such plant exists, at a location nearest the

primary discharge point, a notice of intention to apply. An applicant, not being

the local authority in whose functional area the relevant waste water discharge,

or discharges, to which the relevant application relates, takes place or is to take

place, must also notify the relevant Local Authority, in writing, of their intention

to apply.

An application for a licence must be submitted on the appropriate form (available

from the Agency) with the correct fee, and should contain relevant supporting

documentation as attachments. The application should be based on responses to

the form and include supporting written text and the appropriate use of tables

and drawings. Where point source emissions occur, a system of unique reference

numbers should be used to denote each discharge point. These should be simple,

logical, and traceable throughout the application.

The application form is divided into a number of sections of related information.

The purpose of these divisions is to facilitate both the applicant and the Agency in

the provision of the information and its assessment. Please adhere to the

format as set out in the application form and clearly number each section

and associated attachment, if applicable, accordingly. Attachments should

be clearly numbered, titled and paginated and must contain the required

information as set out in the application form. Additional attachments may be

included to supply any further information supporting the application. Any

references made should be supported by a bibliography.

All questions should be answered. Where information is requested in the

application form, which is not relevant to the particular application, the

words “not applicable” should be clearly written on the form. The

abbreviation “N/A” should not be used.

Additional information may need to be submitted beyond that which is explicitly

requested on this form. Any references made should be supported by a

bibliography. The Agency may request further information if it considers that its

provision is material to the assessment of the application. Advice should be

sought from the Agency where there is doubt about the type of information

required or the level of detail.

Information supplied in this application, including supporting documentation will

be put on public display and be open to inspection by any person.

Applicants should be aware that a contravention of the conditions of a waste

water discharge licence is an offence under the Waste Water Discharge

(Authorisation) Regulations, 2007.

The provision of information in an application for a waste water

discharge licence which is false or misleading is an offence under

Regulation 35 of the Waste Water Discharge (Authorisation)

Regulations, 2007 (S.I. No. 684 of 2007).

Note: Drawings. The following guidelines are included to assist applicants:

• All drawings submitted should be titled and dated.

• All drawings should have a unique reference number and should be signed by a

clearly identifiable person.

• All drawings should indicate a scale and the direction of north.

• All drawings should, generally, be to a scale of between 1:20 to 1:500,

depending upon the degree of detail needed to be shown and the size of the

facility. Drawings delineating the boundary can be to a smaller scale of between

1:1000 to 1:10560, but must clearly and accurately present the required level

of detail. Drawings showing the waste water treatment plant location, if such a

plant exists, can be to a scale of between 1:50 000 to 1:126 720. All drawings

should, however, be A3 or less and of an appropriate scale such that they are

clearly legible. Provide legends on all drawings and maps as appropriate.

• In exceptional circumstances, where A3 is considered inadequate, a larger size

may be requested by the Agency.

It should be noted that it will not be possible to process or determine the

application until the required documents have been provided in sufficient

detail and to a satisfactory standard.

SECTION A: NON-TECHNICAL SUMMARY

Advice on completing this section is provided in the accompanying Guidance Note.

A non-technical summary of the application is to be included here. The summary should identify

all environmental impacts of significance associated with the discharge of waste water associated

with the waste water works. This description should also indicate the hours during which the

waste water works is supervised or manned and days per week of this supervision.

The following information must be included in the non-technical summary:

A description of:

− the waste water works and the activities carried out therein,

− the sources of emissions from the waste water works,

− the nature and quantities of foreseeable emissions from the waste water works into the

receiving aqueous environment as well as identification of significant effects of the emissions

on the environment,

− the proposed technology and other techniques for preventing or, where this is not possible,

reducing emissions from the waste water works,

- further measures planned to comply with the general principle of the basic obligations of the

operator, i.e., that no significant pollution is caused;

− measures planned to monitor emissions into the environment.

Supporting information should form Attachment No A.1

Killygordon Waste Water Treatment Plant was constructed in 2007 to provide Secondary Treatment

for wastewater generated within the Killygordon catchment. It replaced the old primary settlement

tank which had been the method of sewage treatment since its construction in 1967.

The new scheme provided for a new treatment plant . There was no upgrade to the existing sewer

network. The entire network drains under gravity to the WWTP located to the East of the Village.

There are no combined sewer overflows or pump stations on the network under the control of

Donegal County Council. There is a storm water overflow bypass at the intake to the works, which

discharges directly to the old septic tank on site,which has been refurbished for this purpose as part of

the new upgrade.

The WWTP contains the following elements.

- intake collection manhole

- intake works containing manually racked screen

- storm water overflow bypass facility

- flow measurement and intake sampler

- pump sump

- treatment unit(SBR Tank)

- effluent flow measurement and sampling chamber

- sludge holding tank

- Storm tank

A layout of the Treatment plant is shown in Attachment C of the drawing schedule. The incoming

sewer discharges to the inlet collection manhole which contains a penstock for inlet works

maintenance. The flow moves forward through the manually raked screens and splits into 2 streams.

Each stream is 600PE. (The second flow stream is to be used for future upgrade). Flows in excess of

3times the Dry Weather Flow(DWF) pass into the storm tank. Measured flows up to 3DWF pass into

the pump sump. The pump sump has a capacity of 2 hours at 3 DWF. The waste water then passes to

the treatment system. A sequential batch reactor is adopted as the form of treatment.

Most activated sludge plants perform the two fundamental aspects of the activated sludge process in

two tanks. SBR’s allow for both processes to be carried out in one tank.

This process allows aeration, settlement and decanting to occur employing a five-stage cycle: fill,

react, settle, empty and rest.

Waste Water enters the reactor during the fill stage; it is aerobically treated in the react stage; the

biomass settles in the settle stage; the supernatant is decanted during the empty stage; sludge is

withdrawn from the reactor during the rest stage; and the cycle commences again with a new fill

stage.

The following diagram explains how the system operates.

The effluent flow is measured and sampled using a composite sampler. It discharges to the River

Finn approximately 350m upstream of Killygordon Bridge.

Sludge is drawn off periodically and stored in the Sludge Holding Tank. It has a 27 days holding

capacity. There are 3 decant levels which return the supernatant liquid to the head of the works.

Sludge is removed from site when required and sent to the Sludge Hub in Donegal Town for

treatment.

Operation and maintenance of the treatment plant and sewer network is carried out by the Waste

Water inspector.

The WWTP has a design capacity of 600PE and serves an existing population equivalent of 561.

There are currently two planning permission for a total of 59 houses which need the inclusion of a

pump station in order that the development may be serviced by the sewage works. A specific

development charge has been levied on the planning permission so as to ensure that works necessary

to serve these developments can be carried out.

The long term development of the area would see waste water from Crossroads also being treated at

Killygordon WWTP. Phase 2 of the WWTP would need to be implemented before this could proceed.

This would involve the expansion of the WWTP by the inclusion of an additional SBR and associated

equipment and increased sludge capacity. It would also require the construction of a municipal waste

water pumping station in Crossroads to transfer all waste water to Killygordon. These works are

proposed to be delivered by a developer led scheme. A special development contribution scheme is in

place so as to allow the collection of the necessary funding.

The results of sample monitoring of the outlet shows the discharge to be in compliance under normal

conditions with the Urban Waste Water Treatment Directive of 25mg/lBOD, and 125mg/lCOD. The

SS requirement of 35mg/l has on 2 occasions exceeded the required limit.

Killygordon WWTP is monitored 6 times/year in accordance with the requirements of the UWWTD.

Receiving water quality is also monitored as part of this programme. Results of effluent quality

monitoring is shown on attachment E.4 of the Text Schedule. Environmental monitoring is shown on

E.2 and F.1.

B.10 Capital Investment Programme

State whether a programme of works has been prioritised for the development of infrastructure

to appropriately collect, convey, treat and discharge waste water from the relevant

agglomeration. If a programme of works has been prioritised provide details on funding, (local

or national), allocated to the capital project. Provide details on the extent and type of work to be

undertaken and the likely timeframes for this work to be completed.

The WWTP has a design capacity of 600PE and serves an existing population equivalent of 561.

There are currently two planning permission for a total of 59 houses which need the inclusion of a

pump station in order that the development may be serviced by the sewage works. A specific

development charge has been levied on the planning permission so as to ensure that works necessary

to serve these developments can be carried out.

The long term development of the area would see waste water from Crossroads also being treated at

Killygordon WWTP. Phase 2 of the WWTP would need to be implemented before this could proceed.

This would involve the expansion of the WWTP by the inclusion of an additional SBR and associated

equipment and increased sludge capacity. It would also require the construction of a municipal waste

water pumping station in Crossroads to transfer all waste water to Killygordon. These works are

proposed to be delivered by a developer led scheme. A special development contribution scheme is in

place so as to allow the collection of the necessary funding. It is not possible at this time to predict a

timeframe for the necessary work to take place due to the present economic climate.

Attachment B.10 should contain the most recent development programme, including a copy of

any approved funding for the project and a timeframe for the completion of the necessary works

to take place.

SECTION C: INFRASTRUCTURE & OPERATION

Advice on completing this section is provided in the accompanying Guidance Note.

C.1 Operational Information Requirements

Provide a description of the plant, process and design capacity for the areas of the waste water

works where discharges occur, to include a copy of such plans, drawings or maps, (site plans and

location maps, process flow diagrams), and such other particulars, reports and supporting

documentation as are necessary to describe all aspects of the area of the waste water works

discharging to the aquatic environment. Maps and drawings must be no larger than A3 size.

Killygordon is located on the N15 about 4 miles from Ballybofey and 10 miles from Lifford. It is a

small village containing a post office, a shop and a public house. It has seen a lot of housing

development in recent years and provides a quiet residential location for people working in the

Letterkenny/Lifford areas. The village of Crossroads is approximately .5 miles off the main road.

As part of a new private housing development scheme a new Waste Water Treatment Plant was

constructed in conjuction with Donegal County Council in 2007. This replaced an overloaded

Primary Settlement Tank, which was the method of Waste Water Treatment for the area, since it’s

construction in 1967.

The Waste Water treatment plant provides Secondary Treatment to the waste water by means of a

Sequential Batch Reactor, with the treated effluent discharging to the River Finn. (see Non -

Technical Summary, Section A for details of the treatment process).

Proposals for future development

There are plans to connect Crossroads village to the WWTP. This would accommodate existing

houses not able to connect, at present, to the works and planned housing developments not yet

constructed. These works are proposed to be delivered by a developer led scheme. A special

development contribution scheme is in place so as to allow the collection of the necessary funding.

This work would facilitate the Domestic and Commercial growth of both villages.

It is not possible at this stage to indicate a timeframe for this upgrade, due to the

present economic situation, but when the scheme does go ahead it will accommodate the villages

future waste water treatment requirements.

Sampling and monitoring

There are 3 flow measurement devices on site. These are located at

1. intake

2. treated outlet

3. storm overflow

There are 2 composite samplers on site. These are located at

1. intake

2. treated outlet

An individual record (i.e., row) is required for each monitoring and sampling point. Acceptable

file formats include Excel, Access or other upon agreement with the Agency. A standard Excel

template can be downloaded from the EPA website at www.epa.ie. This data should be

submitted to the Agency on a separate CD-Rom containing sections B.1, B.2, B.3, B.4, B.5, C.1,

D.2 and F.2.

E.4 Sampling Data

Regulation 16(1)(h) of the Waste Water Discharge (Authorisation) Regulations 2007 requires all

applicants in the case of an existing waste water treatment plant to specify the sampling data

pertaining to the discharge based on the samples taken in the 12 months preceding the making of

the application.

Regulation 16(1)(l) of the regulations requires applicants to give details of compliance with any

applicable monitoring requirements and treatment standards.

The receiving waters into which the primary discharge from Killygordon WWTP takes place is

monitored by Donegal County Council. The design capacity of the WWTP is 600 p.e and is therefore

sampled 6 times/year. This programme is directed by the Urban Waste Water Treatment Regulation

requirements.

SECTION F: EXISTING ENVIRONMENT & IMPACT OF THE

DISCHARGE(S)

Advice on completing this section is provided in the accompanying Guidance Note.

Detailed information is required to enable the Agency to assess the existing receiving

environment. This section requires the provision of information on the ambient environmental

conditions within the receiving water(s) upstream and downstream of any discharge(s).

Where development is proposed to be carried out, being development which is of a class for the

time being specified under Article 24 (First Schedule) of the Environmental Impact Assessment

Regulations, the information on the state of the existing environment should be addressed in the

EIS. In such cases, it will suffice for the purposes of this section to provide adequate

cross-references to the relevant sections in the EIS.

An EIS was not required for this application. See Text Schedule Attachment F.1 for Habitats

Directive Article 6 Assessment.

F.1. Assessment of Impact on Receiving Surface or Ground Water

o Give summary details and an assessment of the impacts of any existing or proposed

emissions on the environment, including environmental media other than those into which

the emissions are to be made.

Killygordon Waste Water Treatment Plant was constructed in 2007 to provide Secondary Treatment

for wastewater generated within the Killygordon catchment. It replaced the old primary settlement

tank , which had been the method of sewage treatment since its construction in 1967. Since it’s

commissioning the quality of effluent discharging from the WWTP has been in compliance with the

requirements of the UWWT Regulations.

Results shown on attachment F.1 of the Text Schedule show little change between the upstream and

downstream Biochemical Oxygen Demand and Suspended Solids readings. The effluent quality

results from the discharge shows it to be in compliance with the requirements of the UWWT

Regulations of 25mg/lBOD, 35mg/lSS and 125mg/l COD. There were 2 occasions however when the

suspended solids level were slightly over the limit. The average concentration as seen on attachment

E.4 (for the results shown) give a 8mg/lBOD, 23mg/lSS and 58mg/lCOD.

o Details of all monitoring of the receiving water should be supplied via the following web

based link: http://78.137.160.73/epa_wwd_licensing/. Tables F.1(i)(a) & (b) should be

completed for the primary discharge point. Surface water monitoring locations upstream

and downstream of the discharge point shall be screened for those substances listed in

Tables F.1(i)(a) & (b). Monitoring of surface water shall be carried out at not less than

two points, one upstream from the discharge location and one downstream.

o For discharges from secondary discharge points Tables F.1(ii)(a) & (b) should be

completed. Furthermore, provide summary details and an assessment of the impacts of

any existing or proposed emissions on the surface water or ground (aquifers, soils, sub-

soils and rock environment), including any impact on environmental media other than

those into which the emissions are to be made.

Not applicable. There are no secondary discharge points.

o Provide details of the extent and type of ground emissions at the works. For larger

discharges to groundwaters, e.g., from Integrated Constructed Wetlands, large scale

percolation areas, etc., a comprehensive report must be completed which should include,

inter alia, topography, meteorological data, water quality, geology, hydrology, and

hydrogeology. The latter must in particular present the aquifer classification and

vulnerability. The Geological Survey of Ireland Groundwater Protection Scheme Dept of

the Environment and Local Government, Geological Survey of Ireland, EPA (1999)

methodology should be used for any such classification. This report should also identify

all surface water bodies and water wells that may be at risk as a result of the ground

discharge.

Not applicable. There are no ground emissions from the works.

o Describe the existing environment in terms of water quality with particular reference to

environmental quality standards or other legislative standards. Submit a copy of the most

recent water quality management plan or catchment management plan in place for the

receiving water body. Give details of any designation under any Council Directive or

Regulations that apply in relation to the receiving water.

The treated effluent from Killygordon WWTP discharges into the River Finn (01/F/01). In addition

to legislation under the Water Framework Directive(2000/60/EC) the river has been classified as a

Salmonid River under S.I. No 293/1988:European Communities(Quality of Salmonid Waters)

Regulations.

The receiving waters of the River Finn is a designated SAC.

The River Finn is located within the North Western International River Basin District in County

Donegal. This Subbasin Waterbody (waterbody code IE_XB_01_1) has an overall risk category under

the Water Framework Directive of 1a, Water Body “at risk”, overall status “Poor” and overall

objective to “restore”.

The environmental objective of “good status” to be achieved for surface waters, expressed in terms of

Q value, is a value of 4 or greater, by 2015. The EPA interim report on the biological survey of River

Quality(2004) gives a Q rating of 3-4 on the downstream sample from the WWTP at station 0900

“Bridge S. of Killygordon” indicating an unsatisfactory condition.

o Provide a statement as to whether or not emissions of main polluting substances (as

defined in the Dangerous Substances Regulations S.I. No. 12 of 2001) to water are likely

to impair the environment.

There is no evidence to suggest that there are sources within the Agglomeration or in the discharge

itself, which would lead to emissions of the main polluting substances (as defined in the dangerous

substances regulations S.I. No.12 of 2001) at levels, which would be likely to impair the environment.

o In circumstances where water abstraction points exist downstream of any discharge

describe measures to be undertaken to ensure that discharges from the waste water

works will not have a significant effect on faecal coliform, salmonella and protozoan

SECTION G: PROGRAMMES OF IMPROVEMENTS

Advice on completing this section is provided in the accompanying Guidance Note.

G.1 Compliance with Council Directives

Provide details on a programme of improvements to ensure that emissions from the agglomeration

or any premises, plant, methods, processes, operating procedures or other factors which affect

such emissions will comply with, or will not result in the contravention of the;

• Dangerous Substances Directive 2006/11/EC,

• Water Framework Directive 2000/60/EC,

• Birds Directive 79/409/EEC,

• Groundwater Directives 80/68/EEC & 2006/118/EC,

• Drinking Water Directives 80/778/EEC,

• Urban Waste Water Treatment Directive 91/271/EEC,

• Habitats Directive 92/43/EEC,

• Environmental Liabilities Directive 2004/35/EC,

• Bathing Water Directive 76/160/EEC, and

• Shellfish Waters Directive (79/923/EEC).

Killygordon Waste Water Treatment Plant was constructed in 2007 to provide Secondary Treatment

for wastewater generated within the Killygordon catchment. It replaced the old primary settlement

tank which had been the method of sewage treatment since its construction in 1967.

The WWTP has a design capacity of 600PE and serves an existing population equivalent of 561.

There are currently two planning permission for a total of 59 houses which need the inclusion of a

pump station in order that the development may be serviced by the sewage works. A specific

development charge has been levied on the planning permission so as to ensure that works necessary

to serve these developments can be carried out.

The long term development of the area would see waste water from Crossroads also being treated at

Killygordon WWTP. Phase 2 of the WWTP would need to be implemented before this could proceed.

This would involve the expansion of the WWTP by the inclusion of an additional SBR and associated

equipment and increased sludge capacity. It would also require the construction of a municipal waste

water pumping station in Crossroads to transfer all waste water to Killygordon. These works are

proposed to be delivered by a developer led scheme. A special development contribution scheme is in

place so as to allow the collection of the necessary funding.

It is not possible at this time to state a timeframe for the project but once complete will cater for waste

water treatment within the Killygordon/Crossroads catchmant area.

Attachment G.1 should contain the most recent programme of improvements, including a copy

of any approved funding for the project and a timeframe for the completion of the necessary

works to take place.

Executive Summary

Article 6 assessments are required under the Habitats Directive (92/43/EEC), and are required

where a plan or project may give rise to significant effects upon a Natura 2000 site. Natura

2000 sites are those identified as sites of Community importance designated under the

Habitats Directive (Special Areas of Conservation, here after referred to as SACs) or the

Birds Directive (Special Protection Areas, here after referred to as SPAs). In the case of the

present assessment, Ramsar sites are also included by way of best practice. It is important to

note that the phrase ‘Appropriate Assessment’ is sometimes used more loosely to refer to the

whole process set out under Articles 6(3) and 6(4) of the Habitats Directive (Dodd et al.,

2008), and therefore note that for the present assessment the term ‘Article 6 assessment’ will

be used, not ‘Appropriate Assessment’ (which refers to Stage 2 in the sequence under Article

6 assessment).

Guidance on Strategic Environmental Assessment (SEA) produced by the EPA (EPA, 2008)

provides a useful definition of Article 6 assessments (referred to as appropriate assessment in

that document) (EPA, 2008): “An assessment based on best scientific knowledge, of the

potential impacts of the plan on the conservation objectives of any Natura 2000 site

(including Natura 2000 sites not situated in the area encompassed by the draft plan or

scheme) and the development, where necessary, of mitigation or avoidance measures to

preclude negative effects”. Importantly, an Article 6 assessment has a narrow focus i.e. the

maintenance of the integrity of the site and assessing the significance of the effects on

designated interest features and the conservation objectives of the site. It is a protection led

assessment and is carried out using the precautionary principle.

The assessment of the present proposal for licensing the Waste Water Discharge at

Killygordon concluded the following:

The screening process has been undertaken to identify the qualifying interests on the R. Finn

SAC Natura 2000 site and potential impacts arising from the Killygordon Wastewater

treatment plant.

The process has shown that it is unlikely there is any significant effects on the two species

listed as water dependant qualifying interests on the Natura 2000 site arising from the

Killygordon Wastewater Treatment Plant. It is unlikely that there will be ‘in combination’

negative effects from any other additional plans or developments in the catchment. The

current operation of the plant in question is desirable in order to mitigate the impact of what

would otherwise be untreated waste water generated by the Killygordon agglomeration. The

consequences of not operating the plant would have a far more significant negative effect on

this Natura 2000 site hence its continued operation is essential.

Introduction

Article 6 is one of the most important articles of the Habitats Directive in determining the

relationship between conservation and site use. Article 6(3) requires that “Any plan or

project not directly connected with or necessary to the conservation of a site but likely to

have a significant effect thereon, either individually or in combination with other plans or

projects, shall be subject to appropriate assessment of its implications for the site in view of

the site’s conservation objectives.” The purpose of this report is to describe how that Article

6 assessment was carried out, and also to detail the results and conclusions from the

assessment.

Waste Water Discharge (Authorisation) Regulations

Local Authorities are required to carry out an Appropriate Assessment as per article 6 of the

Habitats Directive (92/43/EEC (2000)) in relation to waste water authorisations pursuant to

the Waste Water Discharge (Authorisation) Regulations, 2007 (S.I. No. 684 of 2007).

The specific objectives of the WWDA Regulations are contained within the regulations.

Article 6 assessment

The Council Directive 92/43/EEC on the Conservation of Natural Habitats and of Wild Fauna

and Flora better known as “The Habitats Directive” provides the framework for legal

protection for habitats and species of European importance. Articles 3 to 9 provide the

legislative means to protect habitats and species of Community interest through the

establishment and conservation of an EU-wide network. The Habitats Directive and the

Birds Directive and sites designated under them form this network of European protected

sites that are better known as the Natura 2000 network. This consists of;

Special Areas of Conservation (SACs) for flora, fauna and habitats of Community interest

under the EU Habitats Directive;

Special Protection Areas (SPAs) for rare, vulnerable or migratory birds under the EU Birds

Directive;

Sites that are being considered for designation as one of the above are referred to as cSAC

(candidate) or pSPA (proposed).

Ramsar sites are wetlands of global importance, listed under the Convention on Wetlands of

International Importance. Ramsar sites are contained within Natura 2000 sites and for that

reason, and in line with best practice, Ramsar sites, if present would have been included in

this assessment.

Article 6 sets out provisions which govern the conservation and management of Natura 2000

sites. Article 6(3) and 6(4) of the Habitats Directive set out the decision-making tests for

plans and projects likely to affect Natura 2000 sites. Article 6(3) establishes the requirement

for Appropriate Assessment:

“Any plan or project not directly connected with or necessary to the management of the

[Natura 2000] site but likely to have a significant effect thereon, either individually or in

combination with other plans and projects, shall be subjected to appropriate assessment of its

implications for the site in view of the site’s conservation objectives. In light of the

conclusions of the assessment of the implication for the site and subject to the provisions of

paragraph 4, the competent national authorities shall agree to the plan or project only after

having ascertained that it will not adversely affect the integrity of the site concerned and, if

appropriate, after having obtained the opinion of the general public”

This assessment is underpinned by the precautionary principle, especially in the assessment

of potential impacts and their resolution. If it is not possible to rule out a risk of harm on the

evidence available then it is assumed a risk may exist and it needs to be dealt with in the

appropriate assessment process.

Stages of the Article 6 assessment

The stages of an Article 6 assessment are outlined in the European Commission

Methodological Guidance on the provision of Article 6(3) and 6(4) of the ‘Habitats’ Directive

92/43/EEC (EC 2001) and the European Commission Guidance ‘Managing Natura 2000

Sites’. These are set out below in line with EPA guidance on Appropriate Assessment for

Waste Water Discharge Licensing.

Stage 1 - Screening

Step 1: Management of the site. In the case of all waste water discharges the project is not

connected with, or necessary to the management of a Natura 2000 site

Step 2: Description of the Project (in this case the Killygordon WWTP) and identification of

European sites that may be affected (including ‘in combination’ effects)

Step 3: Characteristics of the site identifying areas where the project may impact on European

sites.

Step 4: Assessment of Significance. Assessment of the likelihood of significant effects of the

project on European sites, including individual and cumulative impacts. Exclusion of site

where it can be objectively concluded that there will be no significant effects and hence no

requirement to proceed to further stages.

Stage 2 - Appropriate Assessment (AA)

Step 1: Information collation of likely effects of project and impacts on European site.

Step 2: Description of the Natura 2000 sites, including qualifying interests.

Step 3: Identification of the conservation objectives for of these sites and potential significant

impacts likely to occur from the proposal

Step 4: Identification and assessment of mitigation measures against any likely adverse

effects of the Project.

Stage 3 - Assessment of alternative solutions

Step 1: Identification of alternative solutions

Step 2: Assessment of alternative solutions

Stage 4 – Imperative Reasons of Overriding Public Interest

Confirm that there are a) imperative reasons of overriding public interest and b) human health

or safety considerations or important environmental benefits. If this is so then compensation

measures are required for any remaining adverse effect.

Results of Killygordon WWTP Assessment

Stage 1 –Screening

Step 1: Management of the Site.

The project is a WWTP and therefore is not directly connected with or necessary for the

management of the European sites involved.

Step 2: Description of Project and European Sites

Description of the Project

A full description of the project is provided in Sections A and C of the WWD application and

in addition the project is briefly outlined below for convenience.

Killygordon Waste Water Treatment Plant was constructed in 2007 to provide Secondary

Treatment for wastewater generated within the Killygordon catchment. It replaced the old

primary settlement tank which had been the method of sewage treatment since its

construction in 1967.

The new scheme provided for a new treatment plant . There was no upgrade to the existing

sewer network. The entire network drains under gravity to the WWTP located to the East of

the Village. There are no combined sewer overflows or pump stations on the network under

the control of Donegal County Council. There is a storm water overflow bypass at the intake

to the works which discharges directly to the old septic tank on site which has been

refurbished for this purpose as part of the new upgrade.

The WWTP contains the following elements.

- intake collection manhole

- intake works containing manually racked screen

- storm water overflow bypass facility

- flow measurement and intake sampler

- pump sump

- treatment unit(SBR Tank)

- effluent flow measurement and sampling chamber

- sludge holding tank

A layout of the Treatment plant is shown in Attachment C of the drawing schedule of the

Application. The incoming sewer discharges to the inlet collection manhole which contains a

penstock for inlet works maintenance. The flow moves forward through the manually raked

screens and splits into 2 streams. Each stream is 600PE. (The second flow stream is to be

used for future upgrade). Flows in excess of 3times the Dry Weather Flow(DWF) pass into

the storm tank. Measured flows up to 3DWF pass into the pump sump. The pump sump has a

capacity of 2 hours at 3 DWF. The waste water then passes to the treatment system. A

sequential batch reactor is adopted as the form of treatment. Most activated sludge plants

perform the two fundamental aspects of the activated sludge process in two tanks. SBR’s

allow for both processes to be carried out in one tank.

This process allows aeration, settlement and decanting to occur employing a five-stage cycle:

fill, react, settle, empty and rest.

Waste Water enters the reactor during the fill stage; it is aerobically treated in the react stage;

the biomass settles in the settle stage; the supernatant is decanted during the empty stage;

sludge is withdrawn from the reactor during the rest stage; and the cycle commences again

with a new fill stage.

European Natura 2000 Sites

The Killygordon WWTP discharges into the River Finn which is an SAC. This site

comprises almost the entire freshwater element of the Finn and its tributaries– the Corlacky,

the Reelan sub-catchment, the Sruhamboy, Elatagh, Cummirk and Glashagh, and also

includes Lough Finn, where the river rises. The spawning grounds at the headwaters of the

Mourne and Derg Rivers, Loughs Derg and Belshade and the tidal stretch of the Foyle north

of Lifford to the border are also part of the site. The Finn and Reelan, rising in the Bluestack

Mountains, drain a catchment area of 195 square miles. All of the site is in Co. Donegal. The

underlying geology is Dalradian Schists and Gneiss for the most part though quartzites and

Carboniferous Limestones are present in the vicinity of Killygordon. The hills around Lough

Finn are also on quartzite. The mountains of Owendoo and Cloghervaddy are of granite

felsite and other intrusive rocks rich in silica. There are many towns along the river but not

within the site. These include Lifford, Killygordonn, Stranolar and Ballybofey. The site is a

candidate SAC selected for active blanket bog, lowland oligotrophic lakes, wet heath and

transition mires all habitats listed on Annex I of the E.U. Habitats Directive. The site is also

selected for the following species listed on Annex II of the same directive – Atlantic Salmon

and Otter.

The qualifying interests of the River Finn SAC have been identified and tabulated below

(Table 1.0) along with an assessment of water dependence (Curtis et al 2006. North South

Shared Aquatic Resource (NS Share) Register of Protected Areas – Report on the ecological

requirements of water dependent habitats and species designated under the Habitats Directive

NS Share T5 (2)-2.1). The water dependent qualifying interests that could potentially be

impacted by the Killygordon WWTP discharge are the Atlantic Salmon – Salmo

salar,(Species No1106) and the Otter-Lutra lutra ( Species no 1355)

Cumulative, Direct, Indirect, Short & Long Term Effects

The Ballybofey Stranorlar discharge is over 11 Km upstream and hence Ballybofey

Stranorlar is not considered to be creating any significant Cumulative, Direct, Indirect,

Short& Long Term Effects with the Killygordon discharge. The overall water quality of the

River Finn is regarded as moderate with some stretches regarded a poor on the basis of the

2008 EPA report. Macroinvertebrate sampling is the main quality driver. There is ongoing

work on identifying pollution sources of the upper reaches of the catchment where sheep

dipping and forestry are possible causes of less than good status Nutrient discharges from

Agriculture in the catchment are a potential source of eutrophication and as such are subject

to the Good Agricultural Practice Regulations. These regulations (both current and any future

amendments) have been agreed as the appropriate Measure for Agriculture under the Water

Framework Directive Programme of Measures and will be incorporated into the River Basin

District management Plans A plan to protect and restore the otter population to early 1980s

levels nationally has been published by NPWS (see ref. list) This includes references to

mitigating the effect of wastewater discharges.

All salmon spawn naturally in freshwater. Spawning typically occurs in the headwater and

tributary streams of rivers, though it can happen anywhere in a river if the substrate is

suitable. The migration to suitable habitat may commence up to a year before spawning takes

place in autumn-winter, salmon ceasing to feed, directing all their energy instead to

reproduction. Fertilised eggs hatch in spring normally during March-April developing into

free swimming fry within 3-6 weeks. They then quickly develop into parr and feed on aquatic

insects and grow for one to three years in their natal stream. They then pass through a process

known as smolting which includes internal changes in the salt-regulating mechanisms of the

body. The smolts become silvery and change from swimming against the current to moving

with it. These adaptations prepare the smolt for its journey to the oceans and the next phase of

its life cycle. After one to three years at sea feeding on fish the now mature salmon returns

to its natal stream to spawn and thereby complete the life cycle of the species.

During their life cycle salmon are subject to a wide range of pressures. These includes water

quality issues in rivers as a result of point and diffuse source pollution. Disease and parasitic

sea lice can impact on their numbers as well as unsustainable fishing practices and other

anthropogenic activities which impact on water quality and habitat.

The Loughs Agency who are the Fishery Board for the Finn catchment in their 2008 report on

status of the Atlantic Salmon in the River Finn regard the species as at Favourable

Conservation Status.

In the NPWS site synopsis it states “Commercial netting on the Foyle does not begin until

June and this gives spring fish a good opportunity to get into the Finn. The Finn is important

in an international context in that its populations of spring salmon appear to be stable while

declining in many areas of Ireland and Europe”.

Given the scale of the volumetric and nutrient load factors involved in the Killygordon

discharge it is unlikely therefore the discharge is having a significant effect on the receiving

waters of the River Finn. Overall therefore there is no evidence to suggest that the discharge

is having an impact on the status of the Atlantic salmon within the R Finn SAC.

Otter:

The ecology of otters has been the subject of a project under the LIFE Nature programme of

the European Commission, published by Life in UK Rivers. The study shows that otters

require huge territories. Quantities of prey dictate numbers of otters and any factor that

impacts on fish stock numbers can have significant impact. A little eutrophication favours

the species. The food taken by otters has been the subject of a number of studies, and the

main prey of the otter includes fish, frogs, crayfish and eels. Chemical vulnerability relates to

prey (principally fish) and the possibility of PCB contamination. There is no known source

of chemical pollution within the catchment of the Killygordon Treatment Works. The site

synopsis states the otter is widespread throughout the system. Otters are very mobile and the

level of human activity in the area is likely to be having a more prevalent effect on the local

presence of otters within the immediate vicinity of the discharge. Given the scale of the

volumetric and nutrient load factors involved in the Killygordon discharge it is unlikely

therefore the discharge is having a significant effect on the otter population of the catchment.

Other Policies, Plans or Projects

There are proposals for further development Phase 2 of the scheme aimed at including the

sewage from the village of Crossroads into the Killygordon plant. ( See Section C of the

Application). It is unlikely that this will take place within the foreseeable future. A possible

target date is 2021.

Conclusion

The screening process has been undertaken to identify the qualifying interests on the

receiving waters within Natura 2000 site and potential impacts arising from the Killygordon

Wastewater treatment plant. None of the water dependant species have been identified as

being significantly impacted by the current facility. The continued operation of the plant in

question is highly desirable in order to protect, improve or maintain the current conservation

status of Qualifying interest of the Natura 2000 site involved, and the consequences of not

operating the plant would have a far more significant negative effect on this site. In

conclusion the Appropriate Assessment process has determined that the Killygordon WWTP

discharge does not adversely impact in any significant manner on the Natura 2000 site, the

relevant qualifying interests or conservation objectives.
