Receiving Environment Monitoring Program (REMP) The environmental authority holder must develop and implement a Receiving Environment Monitoring Program (REMP) to monitor, identify and describe any adverse impacts to surface water environmental values, quality and flows due to the authorised mining activity. This must include monitoring the effects of the mine on the receiving environment periodically (under natural flow conditions) and while mine affected water is being discharged from the site. For the purposes of the REMP, the receiving environment is the waters of the Dawson River. The REMP should encompass any sensitive receiving waters or environmental values downstream of the authorised mining activity that will potentially be directly affected by an authorised release of mine affected water.

The REMP must: a) assess the condition or state of receiving waters, including upstream conditions, spatially within the REMP area, considering background water quality characteristics based on accurate and reliable monitoring data that takes into consideration temporal variation (e.g. seasonality); b) be designed to facilitate assessment against water quality objectives for the relevant environmental values that need to be protected; c) include monitoring from background reference sites (e.g. upstream or background) and downstream sites from the release (as a minimum, the locations specified in Table F6 Receiving Water Upstream Background and Downstream Monitoring Points); d) specify the frequency and timing of sampling required in order to reliably assess ambient conditions and to provide sufficient data to derive site specific background reference values in accordance with the Queensland Water Quality Guidelines 2009. This should include monitoring during periods of natural flow irrespective of mine or other discharges; e) include monitoring and assessment of dissolved oxygen saturation, temperature and all water quality parameters listed in Table F2 Mine Affected Water Release Limits and Table F3 Release Contaminant Trigger Investigation Levels; f) include, where appropriate, monitoring of 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); g) include, where appropriate, monitoring of macroinvertebrates in accordance with the AusRivas methodology, h) apply procedures and/or guidelines from ANZECC & ARMCANZ 2000 and other relevant guideline documents; i) describe sampling and analysis methods and quality assurance and control; and j) incorporate stream flow and hydrological information in the interpretations of water quality and biological data.

The report must propose interim groundwater trigger values to populate Table I2 Groundwater quality triggers, based on a minimum of eight (8) sampling events per bore; and v. by 31 July 2027, submit a report to the administering authority. The report must propose groundwater standing water level trigger thresholds, derived from the results of the groundwater model required by condition I13(a), to populate Table I3 Groundwater standing water level trigger thresholds; and vi. by 31 July 2028; submit a report to the administrating authority. The report must review the interim groundwater trigger values and propose revised groundwater trigger values to populate Table I2 Groundwater quality triggers based on a minimum of eighteen (18) sampling events per bore; and c) by 30 April 2028, develop and implement the Groundwater Monitoring and Management Program in accordance with condition I12. Note: The reports required by condition I19(a)(ii), I19(a)(iv), I19(b)(iv) and I19(b)(vi) must consider the requirements of the administering authority's, or its successor's, most recent edition of the Guideline: "Using monitoring data to assess groundwater quality and potential environmental impacts" (DES, 2021).

of the environmental authority; and f) does not include a landholder or other party who by written agreement with the environment authority holder has declined to be notified for the purpose of this condition. Protected area means a) a protected area under the Nature Conservation Act 1992; or b) a marine park under the Marine Parks Act 1992; or c) a World Heritage Area. Progressive rehabilitation means rehabilitation (defined below) undertaken progressively or a staged approach to rehabilitation as mining operations are ongoing. Receiving environment, in relation to an activity that causes or may cause environmental harm, means the part of the environment to which the harm is, or may be, caused. The receiving environment includes (but is not limited to): a) a watercourse; b) groundwater; c) land; and d) sediments. Receiving waters means the waters into which this environmental authority authorises releases of mine affected water. Reference site (or analogue site) may reflect the original location, adjacent area or another area where rehabilitation success has been completed for a similar biodiversity. Details of the reference site may be as photographs, computer generated images and vegetation models etc. Permit OFFICIAL Environmental authority EPML00565813 - Dawson Central and North Register of Regulated Structures includes: a) date of entry in the register; b) name of the dam, its purpose and intended/actual contents; c) the consequence category of the dam as assessed using the Manual for Assessing Consequence Categories and d) dates, names, and reference for the design plan plus dates, names, and reference numbers of all document(s) lodged as part of a design plan for the dam; e) name and qualifications of the suitably qualified and experienced person who certified the design plan and 'as constructed' drawings; f) for the regulated dam, other than in relation to any levees - i. the dimensions (metres) and surface area (hectares) of the dam measured at the footprint of the dam; ii. coordinates (latitude and longitude in GDA94) within five metres at any point from the outside of the dam including its storage area iii. dam crest volume (megalitres); iv. spillway crest level (metres AHD). v. maximum operating level (metres AHD); vi. storage rating table of stored volume versus level (metres AHD); vii. design storage allowance (megalitres) and associated level of the dam (metres AHD); viii. mandatory reporting level (metres AHD); g) the design plan title and reference relevant to the dam; h) the date construction was certified as compliant with the design plan; i) the name and details of the suitably qualified and experienced person who certified that the constructed dam was compliant with the design plan; j) details of the composition and construction of any liner; k) the system for the detection of any leakage through the floor and sides of the dam; l) dates when the regulated dam underwent an annual inspection for structural and operational adequacy, and to ascertain the available storage volume for 1 November of any year; m) dates when recommendations and actions arising from the annual inspection were provided to the administering authority; and n) dam water quality as obtained from any monitoring required under this authority as at 1 November of each year.
