That notice was lifted this month after the company complied with orders to empty the pond and build a new lined one.
But Grey District mayor Tania Gibson says that does not go far enough.
“We believe the landfill should never have been consented for this sort of waste in the first place; who builds a dump above a water supply these days?
“We’re unhappy that we weren’t considered an affected party and we’ve written to the Ministry for the Environment asking them to look into how that was allowed to happen.”
Her council had also written to the Ministry of Health alerting it to the potential hazard it believes the dump poses to public health.
“We all learned from Havelock North’s experience and we want to make sure the risks are known to the authorities – in case there’s a major landslide or earthquake and contaminated material comes down, and enters the water supply.”
The Regional Council had declined to give her council information about the investigation and monitoring process, citing legal advice, Gibson said.
“It’s been very frustrating when one council won’t share information with another - they asked us not to go to the ministry, but they’ve left us no option. "
Both the West Coast Regional Council and Taylorville Resource Park Ltd have been approached for comment.
