5.1 Bokashi Logic project proposal
In response to a query, Nelson Regional Sewerage Business Unit Manager, Richard Kirby, advised that it was hoped to have enough details of the Bokashi Logic proposal for the September meeting so that a decision could be made on the next step.
It was suggested that any decision on the Bokashi Logic proposal might need to go to the owners (Tasman District Council and Nelson City Council) because of its significance, as the Nelson Regional Sewerage Business Unit committee only had four voting members.
5.2 Pond Sludge Management
It was noted that the ponds were desludged last in 1994-1996. It was advised that Pond 2 was not completely desludged at that time due to the lack of a location to receive the sludge.
In response to a question, Senior Asset Engineer – Solid Waste, Johan Thiart, advised that the proposal from Gurney Environmental stated that the sludge levels in the ponds would be reduced by 2.5 feet to 12 inches.
In response to a further question, Mr Thiart advised that action needed to be taken on pond 2 within 3 years, and within 7-10 years on ponds 1 and 3.
Mr Thiart advised that he would report back at the September meeting on the possibility of the Cawthron Institute undertaking a study of the capacity of Bell Island to receive the sludge.
In response to a request, Mr Thiart said he would circulate information about the Accel-o-Fac mixers/aerators included in the Gurney Environmental proposal.
Nelson Regional Sewerage Business Unit Manager, Richard Kirby, advised that he would provide information to the September meeting on the proposal received from Gurney Environmental.
5.3 Bell Island Spit Restoration
Nelson Regional Sewerage Business Unit Manager, Richard Kirby agreed to invite the Spit Restoration Group to make a presentation to the Board on their continued activities at the spit area at the December Board meeting.
5.4 Sampling and Laboratory Auditing
Nelson Regional Sewerage Business Unit Manager, Richard Kirby said that the accuracy of sampling and laboratory auditing had been discussed at the last contributor meeting, with a need identified for some processes to be sharpened. It was discussed whether testing was being undertaken in a consistent way and queried if the tests were reliable enough to reveal any systemic problems.
5.5 Trade Waste Agreement Amendments
Senior Asset Engineer – Solid Waste, Johan Thiart, noted that at the previous meeting it had been agreed to decide on the process as a group.
It was also noted that some industries occasionally needed to put an elevated load on the system and this could skew results. An example of this was discharging from log vats. These elevated loads would need to be scheduled around other contributors and it was confirmed that these matters were being discussed with other contributors.

Nelson Regional Sewerage Business Unit Manager, Richard Kirby noted the comments received from survey respondents, with some disappointment considering that costs had been more fairly allocated and a transparent agreed process used.
