6 8 ENVIRONMENTAL REQUIREMENT If the Applicant is proposing to carry out the excavation works within PPA Lot 6098 (Port Hedland Refer to Map in Appendix 1A), or Lot 471 (Damper- Refer to Map in Appendix 1B) and is seeking to specifically: a) undertake excavation of material and move the material from its current location; and/or b) move an existing stockpile of material to another location within or outside these Lots, then the site Environment team must be notified immediately and the following conditions will apply. Note that material must not be moved from the excavation location until all of the below conditions have been satisfied: A soil sampling and laboratory analysis plan must be developed by the Applicant to demonstrate the contamination status of the material. This plan shall be prepared in accordance with the Western Australian Department of Environment Regulation Landfill Waste Classification and Waste Definitions (as amended) and Environment Protection (Control Waste) Regulations 2004 (where relevant). As a minimum, the plan shall outline the total estimated volume of material, a site map showing the location of the material, the number of samples required and where/how they will be collected. The plan shall also state that sampling will be conducted by competent personnel, and all samples will be independently tested at a NATA accredited laboratory. The plan shall be submitted to the relevant PPA Environment and Heritage team for review and written approval. The Applicant shall send a written report to the PPA for review and approval that summarises the outcomes of the material sampling and laboratory analysis, and the proposed destination of the material. The report shall be accompanied by suitable photos, and a copy of the NATA accredited laboratory results. Once the material has been moved from its current location, PPA s relevant site Environment team shall be presented with electronic copies of all waste tracking and/or landfill receipts (where relevant). Note that these requirements exist as both the King Bay Industrial Estate (Lot 471) and Lot 6098 (PPA Site and/or leased areas) are listed under the Contaminated Sites Act SAFE WORK PROCEDURE AND CODE OF PRACTICE The permit holder has to comply with PPA Safe Work Instruction Excavation Work. The Code of Practice is published by the Commission for Occupational Safety and Health, Government of WA and is available on this website: A22895 Page 6 of 13

7 The Code (page iii) applies to: all workplaces in Western Australia covered by the Occupational Safety and Health Act 1984 where excavation occurs, and to all persons with the potential for exposure to hazards resulting from excavation in those workplaces, including: All areas where equipment is used to excavate; and All areas where processes associated with excavation are undertaken. The Code provides guidance to prevent occupational injury and disease in all workplaces where excavation and associated earthworks are performed (page iii). PPA expects that the appropriate practices from this Code of Practice will be observed by the permit holder. 10 COMPETENT PERSON As the nature of excavation work varies from simple excavations to complex ones, the approved contractor representative holder must ensure that the excavation and/or related works are carried out or supervised by a competent person. A competent person, as defined in section 1.3 of Occupational Safety and Health Regulations 1996, is one who has acquired through training, qualification, or experience, or a combination of those things, the knowledge and skills required to do that thing competently. It is expected that the knowledge and skills expected from a competent person will increase as the complexity of excavation increases (page 13 of the Code of Practice). 11 RISK ASSESSMENT AND SAFETY WARNINGS This condition reiterates the importance of Health and Safety of workers and the public in all areas within the jurisdiction of Pilbara Ports Authority. PPA expects that an approved Job Safety Analysis is in place prior to any excavation works taking place. During the duration of the approved works, the permit holder shall put in place all the appropriate warnings to the public and signage on safe access and egress to the area to be excavated. The signs shall be displayed to persons in or entering the area. All excavations that are to be left open overnight must have additional warning devices such as flashing lights in addition to existing barricading, access tape and tags and signage. The appropriate signs shall comply with and shall be used in accordance with AS : Safety Signs for the Occupational Environment. A22895 Page 7 of 13

Where unknown services are found, work is to cease immediately and the Pilbara Ports Authority advised to allow for further inspection. PPA s Electrical Supervisor or Civil Supervisor is to be notified when in ground service locating is required on the East Harbour and the Mechanical Engineer or Electrical Supervisor at Utah BHF and Maintenance Supervisor at Dampier.
