    Management of Site

    The Carna agglomeration and its discharge are neither directly connected

    nor necessary to the management of the Carnsore Point Nature Conservation

    Sites.

    Description of Project

    A description of the waste water works and the activities carried out

    therein:

    The Carna Agglomeration is serviced by Carna Waste Water Treatment

    Plant, which is located adjacent to the public toilets at Carna Beach. The

    plant treats the waste water generated from the public toilets, 4 local

    houses, the local shop and the St Vincent De Paul respite centre only, which

    is solely domestic in nature. There are currently no plans in place to either

    increase the existing plant size or to modify the treatment process.

    The sources of emissions from the waste water works:

    There is one single discharge from the Carna Waste Water Treatment Plant

    which is the Primary Discharge point (SW1), which discharges treated

    effluent to St Georges Channel, just below the low water mark.

    There are no reports of either noise or odour complaints originating from

    the plant.

    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 plant is designed to cater for a population equivalent of 125P.E. or 7.5Kg

    of BOD daily with a 25/35 discharge standard. Based on the calculated

    plant PE of 97, the estimated dry weather flow is 16.19 cubic meters/day,

    assuming 167 l/head/day. There are no plans to increase the plant beyond

    its current size.

    The proposed technology and other techniques for preventing or, where

    this is not possible, reducing emissions from the waste water works:

    There are currently no proposals with regard to the above.

    Further measures planned to comply with the general principle of the

    basic obligations of the operator, i.e., that no significant pollution is

    caused:

    It is Wexford County Councils intention to continue to operate and maintain

    the existing plant to ensure that the above obligations are met.

    Measures planned to monitor emissions into the environment:

    Wexford County Council will monitor the final effluent, in accordance with

    our monitoring regime (4 times per year). This work is undertaken on behalf

    of Wexford County Council by an independent ILAB accredited laboratory.

    The contract for this testing is renewed every three years by open

    procurement. The current contract is with Environmental Services Limited,

    Acorn Business Campus, Mahon Industrial Park, Blackrock, Co. Cork. The

    current contract has just been renewed for a period of 3 years and thus the

    contract will have to be re-tendered under open procurement regulations in

    January of 2012.

    Process Description

    Plant process description

    The Carna Waste Water Treatment plant was constructed in conjunction with

    the public toilets in the 1970s, the plant was upgrade in 2006 with secondary

    treatment installed, utilising the existing primary settlement tank located at

    public toilets adjacent to the beach.

    The plant is designed to cater for a population equivalent of 125P.E. or 7.5Kg

    of BOD daily with a 25/35 discharge standard. Based on the calculated

    plant PE of 97, the estimated dry weather flow is 16.19 cubic meters/day,

    assuming 167 l/head/day. There are no plans to increase the plant beyond

    its current size.

    All flows of waste water to the plant are by gravity. Flow enters the site at

    manhole No. 1, from which flow enters the primary settlement tank where

    gross solids are allowed to settle (settled sludge is removed and disposed by a

    tanker as required, approximately every 16 weeks). This settlement process

    removes approximately 40% of the Total Suspended Solids and 30% of the

    Biological Oxygen Demand (BOD) loading. (The primary settlement tank is

    equipped with a bypass, which in case of a blockage of the inlet to the PST,

    diverts flow around the PST to the outlet Manhole of the PST.

    The outlet manhole of PST is divided into 2 sections, the first section accepts

    flow of settled Waste Water from the outlet of the PST and diverts it to the

    forward pumping Station, from where it is delivered to the forward feed

    station.

    The forward feed station is equipped with 2 number submersible pumps which

    operate as duty/standby and these pump flow to 2 number RBC units which

    operate in parallel. The use of 2 number parallel units is required due to the

    very large variation in loading between off peak winter months and peak

    summer loading, with 1 unit removed from operation in off peak period.

    The RBC’s principle mode of operation is extended aeration, where the

    biological activity is carried out by the biological growth on the surface area of

    the discs, with the oxygen being provided by the rotation of each disc, with

    1/3rd of each disc being submerged and 2/3rd of each disc rotating in air at any

    one time.

    The RBC unit is equipped with a settlement zone, where the suspended humus,

    resulting from biological activity in the RBC, is allowed to settle. Settled final

    effluent is then discharged (by displacement). The humus sludge settlement

    zone is equipped with a sloping floor and a sludge return settlement pump which

    automatically, routinely returns sludge to the primary zone of the RBC.

    From the RBC units the secondary treated effluent is combined and returns to

    the second section of the outlet manhole where it discharges via the outfall to

    St George’s Channel.

    Summary of results

    The table below outlines effluent results from the Carna WWTP, as can be

    Therefore, the only potential source of any possible impact on Carnsore

    Nature Conservation Sites is solely from the discharges to the aquatic

    environment.

    Additionally, the discharge, as outlined above, is pre-existing, with the

    current discharge point in position since the 1970s, therefore, it would be

    fair to infer that, as the original discharge preceded the site designation,

    requirements for knowledge of the existence of the development by, and

    consultation with, all interested parties have been met.

    Assessment of Significance

    Assessment as per Circular Letter L8/08 Appendix 1:

    1. Is the development in a nature conservation site? No.

    2a. Is the development in the surface catchments of a nature

    conservation site? Yes.

    The area at the point of discharge is on the boundary of the Carnsore

    Point SAC, Site Code 002269;

    2b. Is the development in the groundwater catchments or within 5Km of a

    nature conservation site? No.

    3. Are the qualifying habitats and species of the site water dependant?

    Yes.

    Habitats

    • Inter-Tidal Mudflats/ Sand flats

    This habitat is primary confined to area of site which is located by

    moderately exposed shore at Carne beech

    The lower shore is dominated by the bivlve moosusc (Angelus tenuis) and

    crusteracea ( Portumnus Laptipes and Crangon crangon), the mid-shore is

    predominately populated by ploychaete worms and the burrowing amphipod,

    Batyporeia pelagica

    While in the upper region living under drift algae is to be found talirid

    amphipods.

    Reefs

    The site has a number of both inert-tidal and sub tidal reefs, which typically

    are strewn with boulders, cobbles and patches of sand

    The inter – tidal reefs located to the east of Carsore point are moderately

    exposed to wave action, and have extensive areas of granite

    The communities to be found in this region are typical for this habitat type

    The upper shore is populated with junior barnacles,, the limpet Pettella

    Vulgara and Top Shell Osilinu lineatus

    While the mid shore is dominated with knotted wrack (Asophyllum nodossum)

    with the epiphyte (Polysiphonia lanosa)

    The lower shore line population is predominately Fucus serratus and

    occasional LAminainaria digitata and grren algae Cladohhora Rupestris

    Sub-tidal reefs which are exposed to wave action is general are populated

    with Mytilus edulis, Alaria esculenta and the Corallina officanalas . In

    shallow water less exposed to wave action are populated by kelp park

    Laminaria hyperborean , with sponges, hydroids and bryozoans

    The reefs of deeper waters in excess of 10m, are dominated by sea squirts

    Polyclinum aurantium with the bryozoan Flusta foliacea. While in waters at

    23m low lying rocks surrounded with course sand is covered with the bivalve

    Musculus discora.

    The nearest designated shellfish waters, namely Wexford Harbour Outer is

    located in excess of 16Km northwest of the point of discharge SW1.

    Site Conservation Objectives

    Unfortunately the NPWS, as yet, have not completed and issued a

    Conservation Management Plan for the Canrsore SAC

    However, this report envisages that the possible conservation objectives of

    this site can be summarised as follows:

    1. Maintain the range of habitats within the site;

    2. Prevent loss of surface area of habitats within the site;

    3. Ensure no reduction in area or distribution of habitats;

    4. Ensure that individual operations or activities, combined with other

    operations or activities, do not cause a change in typical species

    composition in more than 25% of the area occupied by each of the

    principle community types;

    5. Ensure that the water quality in the site is of sufficient quality to

    maintain the integrity of the principle aquatic community type and

    ensure sufficiently large habitat of suitable quality is available to

    support the long term survival of species associated with the habitat.

    The only potential conflict with the above assumed conservation objectives

    is the possible effects of the discharge on the aquatic environment and its

    dependant qualifying habitats and their supported Floral and Faunal species.

    Background data

    Plant effluent results for Carna WWTP are outlined above, these results

    demonstrated that the plant is operational while within design limits

    The WFD Ballyteige Bannow Management Unit Plan Action Plan, (which

    encompasses the actual point of discharge and majority of the designated

    area,) assesses that there is no risk or potential for impact on water quality

    resulting from Carna WWTP.

    Conclusion

    Given the quality of effluent been discharged, and as the WFD Ballyteige

    Bannow WMU does not assess Carna WWTP nor it discharge as either posing

    a direct nor potential impact to water quality

    It is assessed that the discharge from Carna is not impacting on receiving

    water quality and as such is thus not impacting on water quality of

    designated area.

    Thus the development does not in any way impede nor does not conflict with

    the conservation object of the Nature Conservations sites

    Given that the nearest designated shellfish waters are in excess of 16Km

    from discharge SW1 and that WFD WMU Slaney Estuary assess that Carna

    WWTP does not pose a risk

    It is assessed that there is no potential for impact on these designated

    areas as a result of the Carna discharge SW1

    Cumulative Impacts

    The NPWS site synopsis for Carnsore Point 00269 does not cite any

    cumulative impacts for the designated area.

    Conclusion

    As the WFD Ballyteige Bannow Water Management Unit action does not assess

    Carna WWTP and its discharges as posing cumulative effect (pressure point) on

    the water body which encompasses the designated area it is assessed that the

    discharge from Carna is not having a cumulative impact on the site nor it’s

    qualifying interest

    Mitigation Measures

    While there is no measured or predicted, either direct or cumulative impacts on

    the nature conservation site, arising from Carna Discharge SW1

    The only direct mitigation measure currently in place is to limit connections to the

    WWTP, available capacity to insure no decline in the current position.

    Additional mitigation measures with regards to cumulative effects are outlined

    below, based on WFD Slaney Estuary Water Quality Management Unit Action Plan

    In addition the Wexford Harbour Outer Pollution Reduction programme, has been

    developed and implemented

    The introduction and implantation of both of these plans will not only insure that

    there is no increase in direct / cumulative impacts, but the impacts shall be

    reduced and the required restoration objects achieved

    NB All relevant basic measures, general supplementary measures and SEA mitigation measures apply

    Point

    Sources

    POINT SOURCE:

    WWTP – Refer to table below

    INDUSTRY – Examine the terms of discharge authorisations to determine whether they

    require review for the purpose of compliance with water body objectives including protected

    area objectives and environmental quality standards.

    Diffuse

    Sources

    AGRICULTURE – Good Agricultural Practice Regulations and Enforcement.

    ON-SITE SYSTEMS - Inspection of on-site systems in at-risk areas to ensure that treatment

    systems are adequate and maintained to prevent pollution of waters. Consider connection to

    municipal sewerage systems based on inspections and economic tests.

    Other MORPHOLOGY - SE_12_851 will require Channelisation Investigation to

    determine impact of drainage works.

    OTHER: Protection of drinking water, abstraction control and future licensing.

    Measures included in Shellfish Pollution Reduction Programmes under the

    Shellfish Directive.

    Effect of mitigation measures

    Inter-Tidal Mudflats/ Sand flats

    While there is no predicted potential from either direct or cumulative impacts on

    this habitat nor it’s species resulting from the Carna discharges.

    The implementation of these mitigation measures will insure that direct impacts

    will not occur and the cumulative impacts shall be reduced.

    Reefs

    As there is no predicted either direct or cumulative impacts on theses habitats

    resulting from Carna Discharge, the implementation of these measures will insure

    that no future impacts will occur from Carna discharges and that the cumulative

    effects shall be reduced

    Protected Fauna / Flora

    While the sites is not designated for the presence of list Annex II / Annex I

    species, nor does not contain other rare or protected species and the occurring

    species could be impacted by a reduction in water quality.

    The implementation of theses measures will insure that no future impacts shall

    occur and that cumulative effects shall be reduced
