Health problems caused by dust kicked up by heavy logging traffic are being added to by a carcinogenic oil-based suppressant councils are using outside some properties, the Pipiwai Road Action Group says.
Last month the action group staged a roadblock on the boundary of Far North and Whangarei districts at Pipiwai after a year-long stalemate over the dust problem.
In May it will hold a hikoi in Whangarei timed to coincide with hearings to consider a draft Long Term (2015-2025) Plan, which will include submissions by the group for local seal extension.
Since Northland Regional Council and Northland District Health Board air tests more than a year ago confirmed the size and levels of dust particles breached recommended health standards, independent testing by Hills Laboratories on the material used to hold dust down has shown it is oil-based and a carcinogenic risk.
The use of waste oil on roads is prohibited under the Resource Management Act.
