Re: Notice in accordance with Regulation 25(c)(ii) of the Waste WaterDischarge (Authorisation) Regulations 2007 for Certificates ofAuthorisation (as listed below).
Dear Ms. English,
I refer to the letter from your office dated the 14th December 2010, regardingCertificates of Authorisation for the agglomerations below:
Agglomeration EPA Ref.Belmont A0165-01Shannonbridge A0171-01
An Engineering Consultant and Ecologist have been appointed to carry out anAppropriate Assessment screening and any required assessments on theagglomerations which require a certificate of authorisation.
A screening report has been completed and a copy is attached for you information.The agglomerations of Belmont and Shannonbridge required a full assessment. TheConsultant is currently compiling these and they will be forwarded to you oncompletion.
The table below outlines requested P.E. figures which are approximate figures andbased on house counts, undertaken to date. As there are no flow meters at either ofthe WWTP's, we are unable to determine the actual flows or the maximum averageloading for the agglomeration which takes account of local festival, peak holidaysseasons etc. We consider both WWTP's to be at capacity.

In respect to your third query, a new WWTP was proposed for Shannonbridge. It wasplanned to construct a pumping station in Belmont to pump sewerage into Ferbane,making the WWTP in Belmont redundant.
Offaly County Council sought approval for these proposals from the Department ofEnvironment Heritage and Local Government (DEHLG) under the Water ServicesInvestment Programme (WSIP) Assessment of Needs 2010 - 2012 on the 23'dOctober 2009. Unfortunately it was not included on the published WSIP for 2010 2012 which was announced the week ending 23'd April 2010.
As no capital funding has been allocated for the construction of the new WWTP orPumping station, we are not able to say at this point in time, how we will fund anymajor upgrades not included in the 2010 - 2012 WSIP.
However, under the WSIP, the DEHLG have allowed for an annual review ofprogress on listed schemes and we will endeavour to use this review to resubmit anapplication for funding in the 1st review of the annual programme.
One original, one copy and an electronic searchable PDF on CD-ROM of theresponse are included also. Please note that the non-technical summaries have beenrevised and are included in our reply.
We trust that this is to your satisfaction however if you wish to seek furtherinformation please do not hesitate to contact either myself or Mr. Gavin Cobbe on057 9346800.

Revised non-technical summary for Shannonbridge (EPA Ref. A0171-01) The Waste Water Works and the activities carried out therein. The existing Waste Water Treatment Works serving Shannonbridge was installed in 1966 and consists of a concrete Imhoff tank and sludge drying beds, located on an area of raised ground on the eastern bank of the River Shannon. Shannonbridge WWTW is located adjacent to the Shannon Callows. This area is a designated proposed Natural Heritage Area (pNHA), Special Area of Conservation (SAC) and Special Protection Area (SPA). Owing to the sensitive nature of the area around the WWTW, Offaly County Council propose to relocate Shannonbridge WWTW to the south east of the village, outside the boundary of the Shannon Callows, to provide a final effluent discharge standard of 25/35 (BOD/SS), in addition to a 2mg/l total phosphorus limit. The proposed BOD and Suspended Solids limits are in line with those set by the Urban Waste Water Treatment Regulations, 2001 (S.I. 254/2001). The wastewater from the village would be pumped from the existing pumping station, located in the village, through approximately 1155m of new rising main, to the new WWTW location. A new outfall, approximately 700m in length, would then discharge the treated effluent to a new location along the River Shannon (Refer to drawings Shannonbridge-09 -10 and -11 in Section B.9 for details). At present, waste water is pumped to the existing WWTW via a 100mm diameter rising main, where it is directed to a concrete Imhoff tank via an inlet chamber. In the Imhoff tank process, waste matter is decomposed through bacterial action. It consists of an upper chamber in which sedimentation takes place, from which collected solids slide down inclined bottom slopes to an entrance into a lower chamber, in which the sludge is then collected and digested. There are two 200mm diameter outlet pipes which lead from the Imhoff tank. One outlet pipe transports the clarified (settled) liquid to a channel adjacent to the sludge drying beds and on to a 225mm diameter outfall pipe, which then discharges the treated effluent to the River Shannon. A 200mm diameter bypass pipe runs around the Imhoff tank from the inlet chamber and connects to this outlet pipe from the tank. The flow to this pipe is controlled via a penstock valve located at the inlet chamber to the Imhoff tank and it is only used during maintenance of the tank. The second outlet pipe runs from the Imhoff tank to the sludge drying beds. Here, surplus sludge withdrawn from the settling process is left to dry for easier handling and disposal. However, as this outlet and the sludge drying beds have been out of commission for a number of years, the sludge is now removed directly from the base of the Imhoff tank and is transported by tanker to Ferbane or Birr for dewatering (depending on the capacity of either WWTW to treat the sludge), prior to onward transportation for landspreading in Borris-in-Ossory, Co. Laois. A total of 110m3 of sludge has been removed from the WWTW in two loads over the previous year. The supervisor attends the WWTW for 2-3 hours a day, seven days a week. The WWTW has exceeded its design life with the result that the quality of the effluent from the plant has deteriorated in recent years

The sources of emissions from the waste water works. The pollution load of the agglomeration for Shannonbridge WWTW arises from the following areas:
The local population The local light industries Local school, college and crèche Local B&Bs, pubs, shops and business premises The Marina
There are 2 townhouses and 2 farmhouses registered with Bord Fáilte, which have 17 tourist beds between them. However, there is not thought to be significant seasonal variations in waste water loading. The marina is equipped with a sewage pump-out facility, which is used to empty on-board sewage storage tanks to the collection system in the village. 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 final effluent from Shannonbridge WWTW is discharged into the River Shannon, with an average discharge volume of 78m3/day. Recent measurements of the quality of the final effluent from the plant show that the normal 25/35 (BOD/Suspended Solids) standard is frequently being exceeded and that, with reference to the Urban Waste Water Treatment Regulations, 2001, the overall standard of treatment provided is unsatisfactory. As previously noted, Shannonbridge WWTW is located adjacent to the Shannon Callows. This area is a proposed Natural Heritage Area (pNHA), Special Area of Conservation (SAC) and Special Protection Area (SPA). Owing to the sensitive nature of the area around the WWTW, and to cater for the longer term needs of the village, Offaly County Council propose to relocate the WWTW to the south east of the village, outside the boundary of the Shannon Callows. This new WWTW would be based on the provision of an extended aeration plant at the site and designed for 500 PE, with a proposed average discharge volume of 112.5m3/day. Final effluent discharge standards of 25/35 (BOD/SS), in addition to a 2mg/l total phosphorus limit are proposed and are in line with those limits set by the Urban Waste Water Treatment Regulations, 2001 (S.I. 254/2001). In addition to the proposed WWTW, the high dilution levels available in the receiving waters would result in no significant effects of the emissions on the environment (refer to Attachment F.1 for details).

The proposed technology and other techniques for preventing or, where this is not possible, reducing emissions from the waste water works. A new sewerage scheme, including works to the collection system and waste water treatment plant, is proposed to provide for the sustainable development of the village over the next 20 years. The new/upgraded system would be constructed based on complete separation of surface water and foul flows from new developments. New storm water sewers are proposed to provide for the collection of surface runoff from new developments and where possible and economic, to remove surface water from the existing combined drainage system. This would relieve the existing foul/combined system of a certain amount of runoff and help avoid excessive flows to the village pumping station, which would undergo a major civil, mechanical and electrical refurbishment, to bring the station to a satisfactory standard. Offaly County Council sought approval for this proposal from the Department of Environment Heritage and Local Government (DEHLG) under the Water Services Investment Programme (WSIP) Assessment of Needs 2010 – 2012 on the 23rd October 2009. Unfortunately it was not included on the published WSIP for 2010 – 2012 which was announced the week ending 23rd April 2010. As no capital funding has been allocated for the construction of the new WWTP, Offaly County Council are not able to say at this point in time, how Offaly County Council will fund any major plant upgrades not included in the 2010 – 2012 WSIP. However, under the WSIP, the DEHLG have allowed for an annual review of progress on listed schemes and Offaly County Council will endeavour to use this review to resubmit an application for funding in the 1st review of the annual programme. A provisional plant layout for the proposed works, based on the provision of an extended aeration plant at the site, is shown on drawing Shannonbridge-10. An extended aeration plant would be considered the most likely process to be ultimately installed. Additional features to the existing plant process would include stormwater tanks, clarifiers and a sludge recycle chamber, all of which would be designed for a PE of 500, and contribute to an overall improvement in the quality of effluent discharged from the WWTW. It is proposed that the plant would comprise at least two hydraulically independent treatment streams so that isolation of one of the streams for the low loads in the early years of operation, and subsequently for maintenance purposes, could be provided.

Further measures planned to comply with the general principle of the basic obligations of the operator, i.e., that no significant pollution is caused. Prevention of pollution: Any alteration/upgrading of the existing infrastructure undertaken by Offaly County Council shall not increase the potential to cause pollution in the environment. In particular, any alterations to the Waste Water Treatment Works will be designed to enable any operator of the facility to prevent pollution of the environment by the following potential contaminants:
Surface water run-off Spillages Solid Waste
The provision of stand-by pumps and process equipment at the WWTW would assist in achieving the effluent discharge standards proposed, particularly during maintenance works. Toxic Substances Offaly County Council operates a trade discharge licensing system under which all significant non-domestic discharges to the collection system in Shannonbridge, and elsewhere in County Offaly, must be licensed by the council. No proposals providing for the discharge of toxic substances above acceptable limits would be permitted. Measures planned to monitor emissions into the environment Offaly County Council undertakes routine monitoring of the influent and effluent water quality at Shannonbridge WWTW, as well as at monitoring stations on the Shannon River. The effluent monitoring is undertaken a minimum of 4 times per year. This exceeds the requirements of the Urban Waste Water Treatment Regulations, which do not specify a minimum annual number of samples for WWTW serving a PE of less than 2,000.

Revised non-technical summary for Belmont (EPA Ref. A0165-01) The waste water works and the activities carried out therein. The existing Waste Water Treatment Works serving Belmont WWTW was installed in 1982 and consists of a communal concrete septic tank located south of the village centre. At present, waste water enters the WWTW via a 225mm diameter combined sewer where it is split into two no. 150mm diameter inlet pipes prior to entering the septic tank. The septic tank system consists of 2No. chambers each with 50m3 capacity and connected to a 150mm diameter outfall pipe. The division of the tank system into two chambers increases the efficiency of the system at removing suspended solids. In the septic tank process, waste matter is decomposed through bacterial action. Inside the septic tank, there are typically three layers. The top layer is the ‘Scum’ layer where organic material floats to the surface. Bacteria in septic tanks biologically convert this material to a liquid. The middle layer is the ‘effluent’ layer where mostly clear water will be found. This clear water is the only layer that enters the outfall pipe. The bottom layer is the ‘Sludge’ layer. This layer is where the inorganic or inert solid materials and the by-products of bacterial digestion are held. The second compartment receives its "load", or liquid mixture, already substantially clarified, as much of the solid material has settled out of the liquid. There is little turbulence in the second chamber as the load enters more slowly through 150mm diameter opes in the separating wall. Both of these factors allow settling of finer suspended solids than cannot occur in the first chamber where incoming material acts to churn up the chamber contents. The two no. 150mm diameter outlets from the separate septic tank compartments convene in a manhole located at the outlet from the septic tank, from which the main 225mm diameter outfall pipe emerges. The treated waste water from the WWTW then discharges approximately 140m from the septic tank to the River Brosna via the 225mm diameter outfall pipe. The wastewater collection system comprises separate foul and surface water sewers ranging up to 375mm diameter. The foul system incorporates a small pumping station servicing 6 properties in a low lying area of the village. There are no stormwater overflows on the collection system. An approximate total of 450m3 of sludge is removed annually from the plant by tanker, over two or three visits, and is transported to Birr for dewatering prior to onward transportation to Tullamore for treatment and disposal. The plant is supervised for 2-3 hours a day, 7 days a week. The sources of emissions from the waste water works. The pollution load of the agglomeration for Belmont WWTW arises from the following areas:
The local population Local sports/social hall Local agricultural farmyard Local B&Bs, pubs and business premises

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 final effluent from Belmont WWTW is discharged into the River Brosna, with an average discharge volume of 40m3/day. Recent measurements of the quality of the final effluent from the plant show that the normal 25/35 (BOD/Suspended Solids) standard is frequently being exceeded and that, with reference to the Urban Waste Water Treatment Regulations, 2001, the overall standard of treatment provided is unsatisfactory. The existing WWTW is nearing the end of its design life and the quality of the effluent from the plant has therefore deteriorated in recent years. It was proposed to upgrade the sewerage scheme for the village of Belmont to provide for the longer term needs and the sustainable development of the village. The new/upgraded system would be constructed based on complete separation of surface water and foul flows from new developments, with a new storm water system to remove surface water from the existing combined drainage system. The works proposed would serve the existing population and the anticipated growth of Belmont to an equivalent population of 500 over the next 20 years. Offaly County Council propose to abandon the existing WWTW at Belmont and provide a new pumping station at the site to transfer all waste water from the village to Ferbane WWTW. The pumping station is to be designed to pump at a rate equal to 6xDWF at 500PE. A new 125mm diameter rising main was proposed to pump the waste water from the existing WWTW at Belmont approximately 3.5km to discharge into the existing foul sewer collection system in Ferbane for treatment at Ferbane WWTW. This proposal may be taken as the highest form of mitigation measures available to the council to ensure that discharges from the agglomeration would not result in significant effects on the environment. Offaly County Council sought approval for this proposal from the Department of Environment Heritage and Local Government (DEHLG) under the Water Services Investment Programme (WSIP) Assessment of Needs 2010 – 2012 on the 23rd October 2009. Unfortunately it was not included on the published WSIP for 2010 – 2012 which was announced the week ending 23rd April 2010.

1.2 Appropriate Assessment – Legislative Context
The EU Habitats Directive (Council Directive 92/43/EEC on the conservation of natural
habitats and of wild flora and fauna) contains a list of rare habitats and species (Annex I
and II respectively); the conservation of these is considered to be of European and
International importance. Similarly, the EU Birds Directive (Council Directive 79/409/EC on
the conservation of wild birds) aims to protect specific bird species considered to be at risk.
Member states have the responsibility to designate geographic sites according to their
conservation value for the aforementioned habitats and species, namely Special Areas of
Conservation and Special Protection Areas, which together form a network referred to as
Natura 2000; see Section 1.4.
Paragraph 3 of Article 6 of the Habitats Directive state that:

6(3) Any plan or project not directly connected with or necessary to the management of the 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. In the light of the conclusions of the assessment of the implications 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.
Where such an assessment finds that all potential impacts cannot be successfully avoided or
mitigated against, then Paragraph 4 of Article 6 is applied:
6(4) If, in spite of a negative assessment of the implications for the site and in the absence
of alternative solutions, a plan or project must nevertheless be carried out for imperative reasons of overriding public interest, including those of a social or economic nature, the Member State shall take all compensatory measures necessary to ensure that the overall coherence of Natura 2000 is protected. It shall inform the Commission of the compensatory measures adopted.
Where the site concerned hosts a priority natural habitat type and/or a priority species, the only considerations which may be raised are those relating to human health or public safety, to beneficial consequences of primary importance for the environment or, further to an opinion from the Commission, to other imperative reasons of overriding public interest.
The statutory agency responsible for Natura 2000 sites is the National Parks and Wildlife
Service of the Department of Environment, Heritage and Local Government. The European
Court of Justice has recently (December 13 2007) issued a judgment in a legal case
against Ireland that found that Ireland has failed in its statutory duty to confer adequate
protection on designated areas. Following on from this the Circular Letter 1/08 & NPWS
1/08 on Appropriate Assessment of Land Use Plans (from the Department of the
Environment, Heritage and Local Government) states that all plans and projects will be
subject to critical assessment to ensure that they comply with all relevant legislation.
AA is a focused and detailed impact assessment of the implications of the plan or project,
alone and in combination with other plans and projects, on the integrity of a Natura 2000
site in view of its conservation objectives. The terms of AA have been worked out in
judgments of the European Court of Justice. The case law has established that assessments
should be undertaken on the basis of the best scientific evidence and methods. Accordingly,

if the consent authority so requires, data and information on the project and on the site and
an analysis of potential effects on the site must be obtained and presented in a Natura
Impact Statement (NIS) which must be presented by the applicant.
Ecological specialists are generally engaged by applicants to undertake the surveys,
research and analysis, with input from other experts (e.g. hydrologists or engineers) as
necessary to prepare the NIS. In general, larger projects will entail a greater amount of
scientific scrutiny. It is the responsibility of the applicant to have the NIS prepared for
submission to the consent authority. Having satisfied itself that the Statement is complete
and objective, the competent authority carries out the AA on the basis of the NIS and any
other appropriate sources of information. In the case of Waste Water Discharge Licensing,
the Environmental Protection Agency is considered to be the competent authority.
There are 4 stages in an Appropriate Assessment as outlined in the European Commission
Guidance document (2001). The following is a brief summary of these steps.
Stage 1 - Screening: This stage examines the likely effects of a project either alone or in
combination with other projects upon a Natura 2000 Site and considers whether it can be
objectively concluded that these effects will not be significant
Stage 2 - Appropriate Assessment: In this stage, the impact of the project on the integrity
of the Natura 2000 site is considered with respect to the conservation objectives of the site
and to its structure and function. The Appropriate Assessment is informed by the Natura
Impact Statement.
Stage 3 - Assessment of Alternative Solutions: Should the Appropriate Assessment
determine that adverse impacts are likely upon a Natura 2000 site, this stage examines
alternative ways of implementing the project that, where possible, avoid these adverse
impacts.
Stage 4 - Assessment where no alternative solutions exist and where adverse impacts
remain: Where imperative reasons of overriding public interest (IROPI) exist, an assessment
to consider whether compensatory measures will or will not effectively offset the damage
to the Natura site will be necessary.

1.3 DoEHLG Circular L8/08
Prior to Stage 1, projects that involve Water Services Investment such as abstractions or
discharges are subjected to initial screening according to flowcharts contained within
DoEHLG Circular L8/08.
This screening flowchart methodology is designed to assist those planning and designing
water services solutions when determining whether AA for Natura 2000/European sites or
habitats & species listed in the annexes of the EU Birds and Habitats Directives is necessary
or not. It should also be applied to NHAs
Water Services infrastructure projects relate to the provision, operation and management
of drinking water and wastewater services. These projects hold a high health and safety
value for the public as well as being of benefit for biodiversity - it is therefore essential
that such projects are screened at the earliest stage to avoid situations where nature
conservation and human health and safety are pitched as competing interests.
This screening methodology will be reviewed regularly to ensure it remains consistent with
the programmes of measures and River Basin Management Plans (RBMPs) currently being
developed under the Water Framework Directive (WFD).
The L8/08 flowchart is reproduced in Figure 1 below. This flowchart is followed for each of
the respective discharges in Appendix I. The outputs and conclusions of this process is
summarised in Section 4.

1.4 Natura 2000 sites
There are two designations which from part of the Natura 2000 network of sites that
require specific ecological protection in Ireland:
Special Areas of Conservation (SACs)
These are sites that have been identified to be of conservation importance in a European
context, based on the habitats and species; both plant and animal; that they support. The
Directive has a number of Annexes. Habitats listed on Annex I are those habitat types of
community interest whose conservation requires the designation of Special Areas of
Conservation. Some of these are known as priority habitats for which there is a particular
obligation for protection. Animal and plant species of community interest whose
conservation requires the designation of Special Areas of Conservation are listed on Annex
II of the Directive.
All SACs are also proposed Natural Heritage Areas. There is a list of Notifiable Actions
which apply to each annexed habitat and species. These are activities for which consent
must be sought from the Minister of Environment, Heritage and Local Government within
SACs. SACs are protected under the Habitats Directive of 1992 (EU Directive 92/43/EEC)
and the Natural Habitats Regulations of 1997 (S.I.94/97).
Special Protection Areas (SPAs)
These are sites of European importance that have been identified as being of conservation
importance on account of the bird species and populations they support. The Directive
directs all member states to take measures to protect all wild birds and to preserve a
sufficient diversity of habitats for all species naturally occurring within their territories, so as
to maintain populations. Species whose status is a cause for concern are specifically
identified for special conservation measures in Annex I of the Directive, and SPAs have
been designated based on either the presence of these species or the presence of
significant numbers of wintering waterfowl.
All SPAs are also proposed Natural Heritage Areas. SPAs are protected under the Birds
Directive of 1979 (EU Directive 79/409/EEC) and the Natural Habitats Regulations of
1997 (S.I.94/97).

2 Results
The findings of applying the L8/08 flowchart to the respective discharges are summarised
in Table 1 below. Best practice was also applied in numerous cases, where the discharges
occur in locations which are spatially highly removed from the receiving Natura 2000
sites.

2a (If the development involves a surface water abstraction/discharge) Is the development in the surface water catchment of a nature conservation site (or part of such a site)?
Yes Go to Step 3
2b (If the development involves a groundwater abstraction/discharge) Is the development in the groundwater catchment or within 5km of a nature conservation site (or part of such a site)?
- -
3 Are the qualifying habitats and species of the site water dependent?
Yes Go to Step 5
4 Is the development in the surface or groundwater catchment of other water dependent Annex II species, other rare or protected species or salmonid waters?
- -
5 Is there a WFD sub-basin plan for the site or its protected habitats/species
No ASSESS IMPACTS*
6 Does this plan cover all potential receptors (habitats/species)?

* The Natura 2000 sites concerned are the River Shannon Callows SAC and Middle
Shannon Callows SPA. The Belmont WWTP discharges the River Brosna, within 4km of the
boundary of the Natura sites. In this case, the proximity of the discharge to the Natura
2000 sites results in a recommendation for a full Appropriate Assessment to be carried
out, despite the small-scale nature of the treatment facility.

Question
Response Output
Is the development in or on the boundary of a nature conservation site NHA/SAC/SPA?
No -
Will nationally protected species be directly impacted? Wildlife Acts (1976 and 2000), Flora Protection order (S.I. 94 of 1999)?
No -
Is the development a surface water discharge or abstraction in the surface water catchment43, or immediately downstream of a nature conservation site with water dependant qualifying habitats/ species44?
Yes Apply flowchart
Is the development a groundwater discharge or abstraction in the ground water catchment1 or within 5 km of a nature conservation site with water-dependant qualifying habitats/species2?
No -
Is the development in the surface water or groundwater catchment of salmonid waters?
Yes Apply flowchart
Is the treatment plant in an active or former floodplain or flood zone of a river, lake, etc?
No -
Is the development a surface discharge or abstraction to or from marine waters45 and within 3km of a marine nature conservation site?
No -
Will the project in combination with other projects (existing and proposed) or changes to such projects affect the hydrology or water levels of sites of nature conservation interest or the habitats of protected species?
No -
43 If there is a WFD sub basin plan for the sites or its protected habitats and the plan covers all potential receptors, i.e. habitats and species, this plan can be used as the basis for screening and impact assessment. 44 Estuaries are considered part of a catchment. 45 Any marine area including estuaries.

* The Natura 2000 sites concerned are the River Shannon Callows SAC and Middle
Shannon Callows SPA. The Ballycumber WWTP discharges to the Brosna River,
approximately 28km upstream of the Natura 2000 sites. Best practice indicates that this
discharge is considered unlikely to have significant adverse effects on the Natura 2000
site owing to the distance from the site and small-scale nature of the treatment facility.
