Acheson and Glover Limited submitted two associated Planning Applications detailing a programme for the future development of Cleggan Quarry, seeking both a time extension for currently approved operations and consent for an area of currently unauthorised mineral extraction.

The rural Setting of Cleggan Quarry

Following receipt of consultation responses from the Water Management Unit of the Northern Ireland Environment Agency, BCL were commissioned to undertake an assessment of the potential impact of the proposed development upon the water environment.

Study and reporting, which included the installation of a network of groundwater monitoring piezometers, were concluded within 7-weeks of BCL’s commission.

Assessment concluded that the proposed development could proceed in-line with current planning guidance and without unforeseen detriment to the water environment, subject to adherence to agreement upon a programme of groundwater and surface water monitoring outlined by BCL.
