NSW Maritime puts sewer plan at risk
PLANS for a sewerage scheme for Iluka and an upgrade of the Yamba sewerage system may have hit a stumbling block.
The Clarence Valley Council will consider today a report from deputy general manager Rob Donges saying NSW Maritime has raised questions about one of the key components of the scheme - a proposed ebb tide release of tertiary treated effluent.
Mr Donges said NSW Maritime had been consulted throughout the design process, but had never given written approval for an ebb tide release location.
“NSW Maritime requested the previously agreed location (on the southern side of the shipping leads clear of an area approved for dredging) be reconsidered due to continual natural southern movement of the channel,” he said.
Mr Donges said council staff suggested a release site in the northern half of the area proposed for dredging, but NSW Maritime opposed the location.
“This requirement in effect places a new constraint on the ebb tide release location to the north of the area approved for dredging,” he said.
“NSW Maritime has also reiterated its preference is for a single release location. While an Iluka release is technically feasible on the northern side of the dredging area, a release for Yamba may not be technically feasible at this location as the volume potentially released from the Yamba scheme is approximately three times that of Iluka and requires greater depth.”
A review of environmental factors is unlikely to be exhibited until the issue is resolved.
