Within the public drinking water source protection area for Drumcliff springs which supplies Ennis
Hydromorphology (land reclamation)
Small point sources (DWWTS and farmyards)
One operational limestone quarry within the Shallee_010 sub-basin but it discharges under S4 licence to the Fergus_040 waterbody to the north
EPA licensed facility located beside the quarry (Licence no. P0771) which discharges to ground within the sub basin. There is no process water discharged, only surface water which is discharged to ground from settlement ponds. The discharge is licensed for suspended solids and pH.
Pressures indicated for Tyshe are agriculture and domestic wastewater
The elevated ammonia concentrations could also indicate the presence of farmyard point sources.
Six domestic wastewater systems with high – very high P impact potential along the north and south tributaries of the Tyshe
Agriculture and urban wastewater are listed as the significant pressures
New WWTP for Ardfert was installed in 2017
Dewatering at the Section 4 quarry
The quarry has a section 4 license and is being dewatered – approximately 2500 m3/d on average
Drinking water abstraction at Ardfert South comes under strain in dry summer
Nitrate concentrations are consistently high
Chloride concentrations are consistently high
Elevated nutrients, including orthophosphate, ammonium and nitrate, as well as sediment, are the significant issues
Hydromorphology The Tyshe River, falls within the Banna Drainage District. Kerry County Council has a statutory duty to maintain this Drainage District. The River Tyshe flows to the sea at Blackrock. The outfall at Blackrock is vulnerable to blockage from build-up of sand (Flood Risk Management Plan for the Tralee Bay-Feale River Basin, 2018). Sand and seaweed are excavated out of the channel opening. These works currently take place at least every two weeks, but this can be daily in the winter months. The annual cost of these works is estimated at approximately €150,000. The drainage systems back up when this outfall at Blackrock is not clear. Maintenance work is also carried out to keep tidal flaps, approx. 600m upstream of the outfall, functioning. Sluice gates are manually operated to close on high tides to prevent tide backing up on Tyshe River, once every few weeks (Flood Risk Management Plan for the Tralee Bay-Feale River Basin, 2018). As part of a national Preliminary Flood Risk Assessment, discontinuing the existing regime of removing silt and debris from the outfall at Blackrock is being explored
South Dublin Co Co refer requests for S261 quarries to the EPA website
But this is not the S261 Register. This is the S19 Register which has been developed to meet the obligations of Regulation 19 of the Extractive Industries Regulations 2009. Each Local Authority is required to enter and maintain entries in this S19 register for all extractive industries within its functional area.
It is unclear is South Dublin CoCo have no S261 quarries outside the S19 list below
Under the AIE Regs to request a list of named quarries with their GPS locations and related water abstraction data, from the dataset known as the Water Abstraction Register
I am submitting the same AIE to both the EPA and LAWPRO (via Tipperary CoCo, as the competent authority for LAWPRO), as I am unclear which entity has oversight for quarry sites For the purposes of this AIE please consider the timeframe 2018-2022
