Stakeholders should note that this document is limited to DER s assessment and decision making under Part V of the Environmental Protection Act Other approvals may be required for the proposal, and it is the proponent s responsibility to ensure they have all relevant approvals for their Premises. Works approval and licence conditions DER has three types of conditions that may be imposed on works approvals and licences. They are as follows; Standard conditions (SC) DER has standard conditions that are imposed on all works approvals and licences regardless of the activities undertaken on the Premises and the information provided in the application. These are included as the following conditions on works approvals and licences: Works approval conditions: , 1.2.1, 1.2.2, and Licence conditions: , , and For such conditions, justification within the Decision Document is not provided. Optional standard conditions (OSC) In the interests of regulatory consistency DER has a set of optional standard conditions that can be imposed on works approvals and licences. DER will include optional standard conditions as necessary, and are likely to constitute the majority of conditions in any licence. The inclusion of any optional standard conditions is justified in Section 4 of this document. Non standard conditions (NSC) Where the proposed activities require conditions outside the standard conditions suite DER will impose one or more non-standard conditions. These include both premises and sector specific conditions, and are likely to occur within few licences. Where used, justification for the application of these conditions will be included in Section 4.

10 3 Executive summary of proposal and assessment API Management Pty Limited (API) is developing the West Pilbara Iron Ore Project (WPIOP) Stage 1, a mining and export project based on the development of a number of iron ore resources located south of Pannawonica. API proposes to construct a putrescible landfill to service the WPIOP Stage 1 accommodation, including the mine village. The proposed landfill is located on Tenement L08/68, underlaid by Red Hill Pastoral Station, approximately 36 km northeast of the Nanutarra-Munjina Road and 70 km east of the North West Coastal Highway. The landfill is surrounded by mining tenure and mining tenements. There are no sensitive land uses within 5 km of the site. The nearest sensitive premises is the Red Hill Homestead, located approximately 25 km northwest of the premises. The predominant land use in the area is pastoral grazing and mineral exploration. The Cane River is approximately 1 km south of the proposed landfill and the landfill is located in the Cane River catchment. There are no permanent surface water features on the site and engineering design has focused on diversion of surface flows around the landfill area. Rainfall and surface water flows are highly variable during the year and between years. The landfill will accept up to 780 tonnes per year of putrescible and inert wastes. It will comprise of 47 trenches measuring 30 m long, 3-5 m deep and 5 m wide. The distance between each trench will be approximately 10 m. Trenches will be opened when and if required over the life of the Project. The landfill is designed and will be operated in accordance with the Environmental Protection (Rural Landfill) Regulations The landfill will not be lined as it is not located near to a sensitive water resource and is underlain by a thick clay deposit. The depth to the water table is estimated at between approximately 13 and 25 metres below ground level (mbgl). Groundwater monitoring bores will be installed both up and down hydraulic gradient of the landfill. API have committed to monitoring groundwater quality during operations. The landfill will be constructed in two Phases (Table 1). Phase 1 involves constructing five trenches in a fenced enclosure. To prevent stormwater ingress during Phase 1 operations, excavated material will be placed in windrows up-gradient of the open trenches. It is expected that the Phase 1 landfill facility will be operating whilst the Phase 2 landfill facility is being constructed. The Phase 2 landfill will be fully fenced with a lockable gate and surrounded by an earthen bund to prevent stormwater inflow. Table 1. Proposed Phases Design factor Phase 1 Phase 2 Approximate capacity 32 tonnes per year 780 tonnes per year Approximate life 2 years 17 years (cumulative) Trenches 5 47 (cumulative) Footprint 0.35 hectares 7.00 hectares (cumulative) To allow for the simultaneous operation of Phase 1 trenches and construction of the remaining Phase 2 trenches, API will be required to submit a partial compliance document upon completion of the construction of Phase 1. API will then need a licence to operate the Phase 1 landfill whilst they continue to construct the remainder of Phase 2. Following completion of Phase 2, a final compliance document will need to be submitted to DEC prior to a licence amendment that allows for the operation of Phase 2.

11 API submitted an application to amend the Works Approval to extend the date of expiry to December 2016 because the works approval will soon expire, the works have not yet commenced, and to align the Works Approval with the installation of the Mine Accommodation Facility under Works Approval W5064/2011/1. There are no changes to the proposed works. Therefore the Works Approval has not been reassessed. The emissions and discharges have previously been assessed to be of low significance if the landfill is constructed in accordance with the works approval supporting documentation. The expiry date has been amended as requested to extend the date of expiry from 10 June 2015 to 31 December 2016, and the Works Approval has been converted to the updated format.
