The Environment Agency reported on 8 September 2026 that a court order now blocks waste from being brought onto Calder Quarry in Elland, Halifax, and prohibits access to the land, subject to certain exceptions. Anyone breaching the order commits a criminal offence. The order was granted at West Yorkshire Magistrates' Court on Thursday 3 September 2026 and lasts six months. The site sits near residential properties, two schools and a railway line, and a criminal investigation into suspected illegal waste activity continues.

The agency said its investigation began in December 2025 after residents reported tipping and odours described as rubbish and rotting food. Its assessment found thousands of tonnes of waste had been dumped, some of it buried, and excavators were seen on site. After further dumping was reported in August 2026, a restriction notice took effect on 1 September, ahead of the court application. Ben Hocking, Yorkshire Area Environment Manager, said inspections confirmed recent dumping and that enforcement would follow where evidence of illegal activity is found.
