Residents in Glyncoch, near Pontypridd, are expressing concerns about safety and the impact of blasting at the nearby Craig yr Hesg quarry. They report that their homes shake, pictures fall from walls, and children are frightened by the blasts.
These concerns follow a recent incident at Taff's Well quarry, six miles away, where a blast led to flooding that forced people from their homes and damaged 15 properties. The Health and Safety Executive (HSE) is investigating this event, which it described as an "isolated incident" while the investigation is ongoing.
Claire Allen, a 40-year-old resident, stated that vibrations and dust from blasting have worsened in recent years, affecting people's chests and causing anxiety. Chris Whiles, a lead campaigner against the quarry's expansion, is calling for an immediate suspension of all blasting until the Taff's Well investigation is complete.
Heidelberg Materials UK, the operator of Craig yr Hesg, has stated its confidence in its safe operation and adherence to all regulatory requirements. Marius Klein, Area Director, noted that Craig yr Hesg has a different geological profile from Taff's Well and no comparable bodies of water that would pose a flooding risk.
Pontypridd MP Alex Davies-Jones has written to the Welsh government seeking reassurances on safety, including whether geological, hydrological, and flood-risk assessments are up to date at Craig yr Hesg. The Welsh government confirmed receipt of the letter but stated that regulation of active mines and quarries falls under the UK government's responsibility.
