About 500 people turned out to a meeting at the Prebbleton Village Hall on Wednesday night to discuss Waste Management Ltd’s plans to expand its facility on Marshs Rd.
Environment Canterbury chief executive Bill Bayfield was in attendance along with the Selwyn District Mayor Sam Broughton.
ECan councillor John Sunckell also attended as did Christchurch City Council Horny Ward councillor Jimmy Chen.
The meeting was broken down into an overview of the resource consent application, an outline of residents concerns and the legal options.
The possibility of pursuing further legal action against ECan's decision to only consult with residents within 500m of the Waste Management Ltd site was discussed.
Mr Bayfield, Mr Broughton, Cr Sunckell and Cr Chen all addressed the crowd. No one from Waste Management Ltd was at the meeting.
ECan also granted three consents for its construction and discharge of stormwater in March 2019.
The consent application currently with ECan is only for activities resulting in discharge to air.
ECan ran a limited notified consent process, which meant only people within 500m of the proposed facility had a chance to have their say.
The plan has prompted a major backlash from nearby residents who are calling for wider consultation.
An online petition to stop the plant's expansion had received more than 4200 signatures on Thursday.
