Where there is any inconsistency between that description of an ERA and the conditions stated by an EA as to the scale, intensity or manner of carrying out an ERA, the conditions prevail to the extent of the inconsistency. An EA authorises the carrying out of an ERA and does not authorise any environmental harm unless a condition stated by the EA specifically authorises environmental harm. A person carrying out an ERA must also be a registered suitable operator under the Environmental Protection Act 1994 (EP Act). Mobile and temporary activities If you operate a mobile and temporary ERA, other than regulated waste transport, you are required to maintain a work diary. You must: - keep the work diary records for 2 years after the last entry; - inform the administering authority within 7 days of the work diary being lost or stolen; - record the information required in the work diary for each location within 1 day of leaving the location.

Permit OFFICIAL Environmental Authority EPML00879413 Contaminated land It is a requirement of the EP Act that an owner or occupier of land give written notice to the administering authority if they become aware of the following: - the presence of, or happening of an event involving, a hazardous contaminant on the land that is causing, or is reasonably likely to cause, serious or material environmental harm (notice must be given within 24 hours); or - if the land is contaminated land - a change in the condition of the land that is causing, or is reasonably likely to cause, serious or material environmental harm (notice must be given within 24 hours); or - a notifiable activity (as defined in Schedule 3) having been carried out, or is being carried out, on the land (notice must be given within 20 business days). For further information, including the form for giving written notice, refer to the Queensland Government website www.qld.gov.au, using the search term `duty to notify'. Take effect Please note that, in accordance with section 200(1) of the EP Act, an EA has effect: (a) if the authority is for a prescribed ERA and it states that it takes effect on the day nominated by the holder of the authority in a written notice given to the administering authority--on the nominated day; or (b) if the authority states a day or an event for it to take effect--on the stated day or when the stated event happens; or (c) otherwise--on the day the authority is issued. However, in accordance with section 200(2) of the EP Act, the day that the EA takes effect may not be before: (a) if the authority is for a resource activity--the day the relevant tenure is granted to the applicant; or (b) if a development permit for a material change of use of premises under the Planning Act 2016 is necessary for carrying out an activity that related to the authority--the day the development permit takes effect; or (c) if an SDA Approval under the State Development and Public Works Organisation Act 1971 is necessary for carrying out an activity that relates to the authority--the day the approval takes effect. If this EA takes effect when the additional authorisation takes effect, you must provide the administering authority written notice within 5 business days of receiving notification of the related additional authorisation taking effect. If you have incorrectly claimed that an additional authorisation is not required, carrying out the ERA without the additional authorisation is not legal and could result in your prosecution for providing false or misleading information or operating without a valid EA. 13 April 2026 Signature Date Giles Bezzina Enquiries: Delegate of the administering authority PO Box 7230, Cairns QLD 4870 Environmental Protection Act 1994 Phone: (07) 4222 5352 Email: ESCairns@detsi.qld.gov.au

Permit OFFICIAL Environmental Authority EPML00879413 Receiving Environment Monitoring Program (REMP) E14 A REMP must be developed and implemented by 30 January 2013 to monitor and record the effects of the release of contaminants on the receiving environment periodically and whilst contaminants are being discharged from the site, with the aims of identifying and describing the extent of any adverse impacts to local environmental values, and monitoring any changes in the receiving water. A copy of the REMP must be provided to the administering authority prior to its implementation and due consideration given to any comments made on the REMP by the administering authority. For the purposes of the REMP, the receiving environment is the waters within 5 km downstream of any release point. E15 The REMP must address (but not necessarily be limited to) the following: a) Description of potentially affected receiving waters including key communities and reference water quality and sediment characteristics based on accurate and reliable monitoring data that takes into consideration any temporal variation (e.g. seasonality); and b) Description of applicable environmental values and water quality objectives to be achieved (i.e. as scheduled pursuant to the Environmental Protection (Water) Policy 2009); and c) Any relevant reports prepared by other governmental or professional research organisations that relate to the receiving environment within which the REMP is proposed; and d) Water and sediment quality targets within the receiving environment to be achieved, and clarification of contaminant concentrations or levels indicating adverse environmental impacts during the REMP. e) Monitoring for any potential adverse environmental impacts caused by the release; f) Monitoring of stream flow and hydrology; g) Monitoring of toxicants should consider the indicators specified in Table E3 to assess the extent of the compliance of concentrations with water quality objectives and/or the ANZECC 2000 guidelines for livestock drinking water guidelines; h) Monitoring of the parameters as a minimum those specified in Table E3 (in addition to dissolved oxygen saturation and temperature); i) Monitoring biological indicators (for macroinvertebrates in accordance with the administering authorities' monitoring and sampling manual (AusRivas methodology) and metals/metalloids in sediments (in accordance with ANZECC & ARMCANZ 2000, BATLEY and/or the most recent version of AS5667.1 Guidance on Sampling of Bottom Sediments) for permanent, semi-permanent water holes and water storages; j) The locations of monitoring points (including the locations specified in Table E2 which are reference/upstream and downstream impacted sites for each release point); k) The frequency or scheduling of sampling and analysis sufficient to determine water quality objectives and to derive site specific reference values within 2 years (depending on wet season flows) in accordance with the Queensland Water Quality Guidelines. For ephemeral streams, this should include periods of flow irrespective of mine or other discharges; l) Specify sampling and analysis methods and quality assurance and control; m) Any historical datasets to be relied upon; n) Description of the statistical basis on which conclusions are drawn; and o) Any spatial and temporal controls to exclude potential confounding factors.
