The Hawke's Bay Regional Council has dropped another of the charges it laid against the Central Hawke's Bay District Council in relation to its wastewater treatment plants at Waipawa and Waipukurau.
Last November, the regional council laid three charges over breaches of the plants' resource consents that allowed for a certain number of E.coli and dissolved reactive phosphorus discharge exceedances during a 12-month period.
One charge regarding a DRP discharge at Waipukurau was dropped in recognition that it had followed a heavy rainfall event in September last year.
Since then another charge related to E.coli and DRP discharges at Waipukurau had also been withdrawn.
This was due to a sample being taken while a filter was being repaired, said CHB District Council technical services manager Steve Thrush.
