The proposed standard, as notified for consultation, was worded as follows.
Part 1 New consents in drinking-water catchments shall only be granted if the proposed activity does not result in drinking-water being non-potable or unwholesome following treatment.
Part 2 Consent authorities will periodically assess the risks within drinking-water catchments to ensure that permitted and unregulated activities do not cause impacts beyond the performance of the affected treatment facilities.
Part 3 Resource consents within drinking-water catchments will have a condition that any unauthorised activity be notified to the water supplier immediately.
Part 4 Resource consents to take water for drinking will have a condition that requires appropriate action, including turning off the supply, if notified of events or activities that make the drinking-water non-potable.
The discussion document noted that the exact wording of any standard will be legally drafted after government decisions.
