Meridian Energy Limited (APP-20233670)
Public notice is hereby given pursuant to S.95A of the Resource Management Act 1991 that the following application for resource consent has been received by Environment Southland.
The application (reference APP-20233670) is related to the construction of a new channel to enable a permanent diversion of part of the flow of the Waiau Arm and the associated removal of bed material and gravels, together with any maintenance and ancillary activities. The project is intended to improve flow conveyance and reliability through the Manapōuri Lake Control structure, and so result in better outcomes for river health in the Lower Waiau River.
The application (reference APP-20233670) is for the following activities related to the construction of a new channel:
- A water permit under section 14 of the RMA to:
- Temporarily take, divert and use water to facilitate construction and maintenance activities, including within and in proximity to wetlands and for dewatering, dust suppression, and erosion and sediment control activities; and
- Permanently divert surface water into the parallel channel.
- A discharge permit under section 15 of the RMA to:
- Temporarily discharge water and suspended sediment to land and water (the Waiau Arm, Mararoa River and Lower Waiau River) for the purposes of facilitating construction and maintenance activities, including within and in proximity to wetlands and for dewatering, dust suppression, and erosion and sediment control activities.
- Permits as required under regulation 47 of the National Environmental Standards for Freshwater (NES-F) for activities under sections 14 and 15 of the RMA, including those associated with:
- Vegetation clearance, earthworks and land disturbance, and the take, use, diversion and discharge of water, in and/or near a natural inland wetland.
The proposal also includes activities which would normally be subject to sections 9 and 13 of the RMA, and which here are authorised by the Manapōuri Te Anau Development Act 1963. This is a special Act of Parliament and enables the construction and ongoing operation of the Manapōuri Power Scheme. Although such activities are outside the scope of this resource consent process, a description of the associated effects and proposed mitigations is included in the application.
Purpose: The existing active channel of the Waiau Arm immediately upstream of the Manapōuri Lake Control Structure is accumulating gravels and bed material, is becoming shallower, and is constrained physically. This is impacting the applicant’s ability to reliably release flows through the structure into the Lower Waiau River at lower lake levels of Lake Manapōuri. The proposal involves the construction of a new channel which is parallel to, and outside the permanently active bed of, the current main channel in the Waiau Arm, maintenance and ancillary activities. The excavated gravel and bed material would be deposited on Meridian-owned land to the north of the new channel, near wetlands.
Location: at and around the Manapōuri Lake Control Structure, including the Waiau Arm at the confluence of the Waiau Arm and Mararoa River at or about NZTM2000 1186068E 4935096N.
Legal Description of Property: Section 1 Survey Office Plan 12223.
