The Canterbury Regional Council has received an application from Lyttelton Port Company for resource consents in respect of its proposed Channel Deepening Project (CDP).
This CDP involves:
The decision of the Hearing Panel on the applications has been released.
The applicant seeks to dredge the area marked ‘Dredging for channel deepening’ as shown on Figure 1, to a depth that allows a vessel with a 14.5 metre draught to enter Lyttelton Port at all tide levels. In addition to that, the applicant seeks to dredge the seabed material at Te Awaparahi Bay in preparation for reclaiming land for a new container facility. Dredge spoil (seabed material) will be disposed of at the channel deepening spoil disposal ground indicated on Figure 1.
The applicant has applied for the following resource consents in relation to the proposed channel deepening dredging:
(1) CRC172455 – A Coastal Permit:
a. to dredge (disturb) seabed material for purposes of deepening, extending and widening a shipping (navigation) channel that includes a ship-turning basin and berth pockets; and
b. to dredge seabed material in preparation for reclaiming land for a new container facility in Te Awaparahi Bay; and
c. to deposit seabed material on the seabed associated with (a) and (b) above.
(2) CRC172522 – A Discharge Permit:
a. to discharge contaminants (seabed material and water) into water associated with channel deepening dredging as described in (1) above.
The applicant seeks to undertake dredging to maintain the navigational channel, ship-turning basin and berth pockets in the area marked as the ‘Deepened shipping channel’ on Figure 2, to a depth required for a vessel with a 14.5 metre draught to enter Lyttelton Port at all tides. Dredge spoil (seabed material) will be disposed of primarily at the offshore maintenance disposal grounds as shown on Figure 2, with the Godley Head spoil disposal ground being retained as an alternative option.
The applicant has applied for the following resource consents in relation to the proposed maintenance dredging.
(3) CRC172456 – A Coastal Permit:
a. to dredge (disturb) seabed material for purposes of maintaining the depth of a shipping (navigation) channel that includes a ship-turning basin and berth pockets; and
b. to deposit seabed material on the seabed associated with 3(a) above;
(4) CRC172523 – A Discharge Permit:
a. to discharge contaminants (seabed material and water) into water associated with maintenance dredging in (3) above.
The application includes an assessment of effects. A consent duration of 35 years is sought for the above four consents.
A 10 year lapse period is sought for the channel deepening dredging consents. A 12 year lapse period is sought for the maintenance dredging consents.

Cultural Impact Assessment updated- November 2016 - Please note that Appendix 3 - Cultural Impact Assessment has been updated. The changes to the Cultural Impact Assessment are in Section 8: Recommendations, and are to delete Recommendation 4 (Environment bond) and replace it with a similar (without bond) recommendation about responsibility for unforeseen effects as follows:
New Recommendation 26 (Unexpected effects) added: Notwithstanding the need to avoid adverse effects by managing the dredging activity within a robust environmental monitoring programme and adaptive management framework, and the expectation that the offshore disposal grounds will be moved to deeper water if effects are observed (Recommendation 9), conditions of consent are required to ensure LPC is responsible for any unforeseen adverse effects on the environment as a result of the activity, and that any such effects are remediated or mitigated using methods agreed to by LPC, the consent authority, and manawhenua.
