Rivrr Boyar Walrr Qualily Managrrnmr PlanCritical Flows and DischargesIn general, the specified water quality standards will be taken to apply only at flows equal to orgreater than the 95 percentile flow. In the case of dissolved oxygen (D.O.), the 99.9 percentile limitof 4 mgll 02 for salmonid waters will apply at all flows including the dry weather flow. Similar flowconditions will apply to the 99.9 percentile limit for oxidised nitrogen of 11 mgll N. Standards fortoxic substances such as heavy metals apply for all flows including the dry weather flow.In calculnting the impact of a waste discharge, the objective should be not to exceed a BOD limit of 4mgll, in order to allow a margin for cany-over from other discharges. An effluent discharge shouldnot result in a BOD increment of more than 2 mg/l02 in the receiving water.6.4 Other Sources of Waste DischargeThe plan must have regard to the existing and potential pollution from waste discbarges other thandomestic or industrial effluent. Such discharges can derive from :-mAgricc~Iture ; including animal manures and silage liqzror cnd fertiliser run-offDomestic Septic Tanks ; organic and nutrient discharges caq prise from unsatisfactory septiclanh and small package systems associated with inadPc.&ate design, poor maintenancc.u~isotisfactory percolation arecs and bypassing direct to$atercourses\3. ,$09.iPeat SiItdion ;[here is evidence of pearsilt&~?n the upper section of [he main channel.7 .\iand it S hlporfant tributaries.

AN discharges from filling stations should be firred with petrol interceptorsto prevent contamination of water courses.Surveys should be carried out to identify and map sources of waste from agriculture. Field surveyshave indicated unsatisfactory effluent storage facilities and lack of control of soiled water from openyard systems. Comprehensive farm surveys are required to establish catchment farm records to beintegrated to the G.I.S. system, together with records of monitoring and pollution incidents. Thissystem should provide the basis for undertaking measures, where necessary, to protect water qualityEPA E\m~ll ,, ..~-2ll~lX~l~ .-,EPA Export 26-07-2013:17:27:02
River Boync Water Quality hlrnsgrmcnl PlanSimilarly, records of septic tank systems should be developed, together with details of their function(domestic house, public house, commercial premises). By incorporating these records into the G.I.S.Data Management System, statistics could be maintained on monitoring results and pollutionincidents associated with such systems.Pollution incidents can also arise from road accidents which result in spillages to water courses.Records of these events should also be maintained. Accident black spots might be identified withparticular reference to water supply abstractions which would be vulnerable to such incidents.Additional studies are recommended to quantify the effects of non-point sources of pollution from thefollowing sources:-* Roadwq run-offBaseline survey ofpersistent organic malter in aquatic organismsSheep dipping and discharge of spent sheep dipDischarges from combined sewer overflows6.5 Monitoring ProgrammesA standardisedPermanentreviewed aridsignijcant water supplycatchment to include the following:-for river flow nionitoririg should berequired, particular!^ bz the vicinip ofdischarges, to be automatic recordirig stationsPhysico-chemical ~armelers~~~iocations of sanrplir7g sites to be reviewed and appropriatefrequency of sampling detemyied for the keyphysico-chemical parameters should be carriedout to include BOD, dissolved oxygen, pH, temperature, suspended solick, phosphate.nitrates, ammonia, nitrite and faecal colijormsFor inspection purposes only.Consent of copyright owner required for any other use.Biological (invertebrate) ; monitoring should be carried ot~l at all EPA reference sites atleast once per yearA Data Management System should be established to store all of the catchment data with facilities forediting and reporting. This should be a G.I.S. system capable of spatial reference. This can beimplemented based on the National Water Services G.I.S., currently being developed by the LocalGovernment Computer Services Board. The system should provide for digital data exchange betweenthe six authorities involved in the catchment and with the EPA National Database, and be compatiblewith the National and E.U. Environmental Information Systems.In this regard, it should be noted that the plan is based on the currently available information, some ofit relying on a limited dataset. The acquisition of additional data from a comprehensive programmeof monitoring would reduce the element of uncertainty in decision making.EPA Export 26-07-2013:17:27:02
