Kia ora,
We're aware that residents in and near Bromley, Linwood and South New Brighton have been experiencing some foul odours over the past few weeks.
This is the information we have so far:
- Council staff have been in contact with Environment Canterbury and have reviewed the activities at the organics processing plant and the composting around the wastewater treatment plant ponds over the summer break.
- Environment Canterbury received six odour complaints in early January. To better understand this odour, we've requested independent environmental experts include observations of any estuary smells during warmer weather and low-tide conditions in their proactive monitoring.
- Environment Canterbury issued a notice of non-compliance (NONC) to the organics processing plant on 10 January 2023, relating to a detection of odour they believe was coming from the organics processing plant on that particular day.
- A NONC essentially advises of a potential breach of consent conditions and requests certain actions be taken. We're investigating the situation and activity at the plant at that time, to better understand what might have been happening on the site to have caused this odour.
- All work spreading compost on the Ruru Road paddocks as part of a native planting programme around the oxidation ponds was stopped over the summer break, and is scheduled to restart on 16 January 2023.
- Some compost was spread by contractors on the Breezes Rd and Dyers Rd paddocks following the standard procedure, but there was no stockpiling or other activities that would have generated the odour reported.
- The oxidation ponds continue to perform well and remain in good health with the interim treatment process, producing very minimal levels of hydrogen sulphide.
