Quarry operating near "sensitive sites" loses challenge over environmental assessment

A quarry operator in County Mayo has failed in a High Court challenge against a requirement to conduct an environmental impact assessment for an extension of its limestone extraction works. McGrath Limestone Works, located near Ashford Castle and proximate to several designated conservation areas including Lough Carra, sought to overturn decisions by Mayo County Council and An Bord Pleanála mandating an EIA as a condition of planning permission. The company contended the requirement was not legally necessary and would effectively force cessation of operations pending compliance. Mr Justice Peter Charleton dismissed all arguments, finding the decisions lawful and reasonable given the site's proximity to environmentally significant tourist resources. The Judge held that no error in law, procedural defect, or inadequacy of reasoning had occurred, and that both the council and the board had properly applied relevant legislation in their assessments.
