Marlborough Quarry Proposal Faces Scrutiny Over Blasting Risks

Gill Construction lodged a resource consent application for Taylor Pass Quarry in Marlborough. The proposal has drawn concern from local residents regarding potential rockfall. During a consent hearing, an engineering geologist for Gill Construction argued that quarry blasting produces only about 1% of the forces experienced during a major event like the Kaikōura earthquake. However, an engineering geologist for the residents argued that repeated blasting could degrade the rock face over time, increasing the risk of rockfall during future flooding or quakes.

The debate over the quarry's risk assessment challenges the regulatory standing of Marlborough District Council, which had previously judged the quarry's effects to be less than minor. The outcome of the review could impact local land use and development plans in Marlborough.
