Augrhrim-Mucklagh Quarry ComplexAughrim & Mucklagh Quarry Complex, Ballyconnell, Co. Cavn

County: Cavan / Fermanagh.
Mineral: Carboniferous Limestone & Shale.
Project: Planning Application for vertical and lateral extensions to 4-no. existing quarries.
Planned Workings: Dry Workings above the watertable.
Mitigation: Compliance Monitoring.
Approximate Consented Reserve: circa 50mt.
Project Areas: EIA, FRA.

The potential for continued working, expansion and restoration of the Quinn Group’s Aughrim / Mucklagh Quarry Complex, Ballyconnell, to impact upon the water environment was assessed as part of an EIA undertaken by BCL.

Sparse site specific hydrogeological data were available at initiation of the study. BCL specified and oversaw the installation of a piezometer network that provided data to aid understanding of the local hydrogeological regime.

Investigations determined that the proposed development would not cause significant harm to the water environment. Extensive consultation with RoI planning authorities led to the development of a scheme of confirmatory groundwater monitoring. BCL managed the installation of automated groundwater level monitoring equipment to the satisfaction of the planning authorities and continues to carry out routine monitoring, data recovery, logger recalibration and reporting in-line with planning requirements.

Gortmullan QuarryUndertaking aquifer pumping-tests, Gortmullan Quarry, County Cavan, RoI, 2012.

County: Cavan.
Mineral: Carboniferous Sandstone & Shale.
Project: Planning Application for vertical and lateral extension to existing quarry.
Planned Workings: Sub-watertable workings with full-depth dewatering.
Mitigation: Compliance Monitoring.
Approximate Consented Reserve: 1mt.
Project Areas: EIA.

The potential for lateral and vertical expansion and subsequent restoration of the Quinn Group’s Gortmullan Sandstone Quarry, near Ballyconnell, County Cavan, to impact upon the water environment was assessed as part of an EIA undertaken during 2012/13 by BCL.

The work built upon the comprehensive understanding of hydrogeological conditions established by BCL’s earlier work for the Group in the area. BCL specified and oversaw the expansion of the existing piezometer network to provide the additional data required for assessment. A series of aquifer pumping-tests were designed and carried out by BCL to aid design of a dewatering scheme for the quarry. The rate of dewatering discharge predicted by the tests was found to be greater than the settlement capacity offered by the area available for construction of lagoons. This difficulty was circumvented by the design of a borehole dewatering programme, informed by the results of the pumping-tests, which will ensure an acceptable quality of off-site discharge without use of settlement facilities.

Investigations determined that the proposed development would not cause significant harm to the water environment.

County: Cavan / Fermanagh.
Mineral: Carboniferous Limestone & Shale.
Project: Hydrometric Monitoring Scheme in compliance with planning conditions.
Planned Workings: Dry Workings above the watertable.
Mitigation: Compliance Monitoring.
Approximate Consented Reserve: circa 85mt.
Project Areas: RHM.

BCL manage, monitor and report upon an extensive network of automated groundwater level loggers to police the impacts of workings upon the water environment and hence allow compliance with planning conditions at two major limestone and shale quarry complexes in County Cavan.

The work has involved on-going monitoring and maintenance of over 30-loggers installed over many hundreds of hectares of rural Ireland. The intensive field-work and reporting undertaken by BCL has freed up the Quarry operators to concentrate upon their core business whilst giving the planning authorities and other stakeholders confidence that planning conditions are being properly and sensibly implemented.

Monitoring, undertaken over 7-years, has determined that the effects upon the water environment are in accord with predictions made at the time of grant of planning permission and that no significant harm is being caused to the water environment.
