Applicant: Protranz International Limited Address for service: C/- WSP 12 Moorhouse Avenue, Christchurch 8011 Attention/ Subject Heading: Whiterock Submission Email: CommunityEngagement@wsp.com

The Waimakariri District Council and Canterbury Regional Council have received resource consent applications from Protranz International Limited to continue a limestone quarry operation and to establish and operate a new managed landfill at 150, 154, 175 and 176 Quarry Road, Loburn.

The applicant requested public notification of the following application made to Waimakariri District Council:

• RC245076: A land use consent for the following activities: earthworks and vegetation clearance within waterway margins, general earthworks for formation of a managed fill landfill, bridge structure within a waterway setback, increased rates of mineral extraction, to operate a managed fill landfill, construction of stormwater outfalls, earthworks and material storage associated with quarrying / landfill construction.

The applicant requested public notification of the following application made to Canterbury Regional Council include CRC243699 – CRC243707: land use consents, water permits and discharge permits for the following activities:

• construction of stormwater outfall pipes, removal of a ford crossing, excavations within 50 m of a surface water body and a wetland, excavations and vegetation clearance outside the bed of a river;
• excavations within <1 m of groundwater and disposal of managed fill material;
• the temporary take and use of groundwater for site establishment, and the take and use of groundwater via the underdrainage system, including the take of water from within 100 m of a wetland, and the take and use of surface water;
• the temporary discharges of site dewatering water, sediment-laden water, and water treatment chemical residuals;
• the discharge of stormwater, water treatment chemical residuals, solid and hazardous waste to land, discharge of water into a wetland; discharge of landfill liner leakage; and
• the discharge of contaminants into air from the development and operation of the landfill, the storage and handling of bulk solid materials, and from the furnace and rotary kiln.

Quarrying and Processing of Lime and Overburden

Quarrying will primarily involve preparation to construct landfill stages within the existing limestone extraction quarry pit. Extracted overburden materials will be processed and used in the landfill liner, cover and capping development. Crushing and drying of limestone will continue to occur and this will be transported off site.

Landfilling

The proposed landfill will be developed in two stages within the reshaped existing quarry pit. The lined landfill footprint will be approximately 4.0 hectares, with a total airspace volume of 500,000 m³.

The landfill is expected to have an operational lifespan of 20 years. The landfill surface is proposed to be progressively restored to match the surrounding natural landforms. A final low permeability capping layer and rehabilitation with grasses or native vegetation are proposed.

Deposition material will include sorted inert construction and demolition materials, and contaminated soils, incl. asbestos containing materials and asbestos in soils. Materials will not include putrescible waste (green waste) or municipal solid waste (from town rubbish collections.) or non-inert construction and demolition materials.

Material transported to the landfill will be in enclosed containers.

Other activities

Other activities include the construction of a single span bridge, stormwater management treatment and discharges, groundwater interception via an underdrainage system and associated discharges, the formation of bunds, improvements to internal roading, and a container transfer area.

Enduring durations have been sought for the land use applications CRC243700 and RC245076.
For short term construction related activities and furnace /rotary kiln emissions the duration sought is 10 years, for longer term operational activities the duration sought is 35 years.
