BCL undertook a hydrogeological and hydrological impact assessment of the proposed extraction and restoration of a new high PSV hardrock quarry proposed by Conexpo (NI) Ltd within lands near Lisburn, County Down. Working of the site would yield some 8.3 million tonnes of saleable mineral from within an overall footprint of some 18.9 hectares over some 20-years of operation.
