If areas irrigated with effluent are accessible to employees or the general public, prominent signage must be provided advising that effluent is present and care should be taken to avoid consuming or otherwise coming into unprotected contact with the effluent.
- F13
The Maximum irrigation rate must be calculated as per Table 1 - Irrigation Requirements of the `Eligibility
- F14
The daily volume of effluent release to land must be measured and records kept of the volumes of effluent released.
- F15
Treated sewage effluent must only be dispersed in accordance with the following outcomes: Permit Environmental authority a) Efficient application of effluent utilising best practice methods; b) Minimal degradation of soil structure; c) Prevention of: i. run-off of effluent or seepage from irrigation areas by limitation of application rates and the use of structures such as bunds, catch dams and the Production Evaporation Dam; ii. surface ponding; iii. damage to native vegetation; d) Provide prominent signage, in areas irrigated with effluent and which are accessible to the employees and general public, advising that effluent should not be consumed or used; e) Maximise health and safety protection in relation to effluent handling and irrigation; and f) Irrigation areas are adequately identified.
- F16
Sewage effluent released to land must not cause spray drift or over spray to any odour sensitive place. Erosion and sediment control
- F17
The holder of the environmental authority must design, install and maintain adequate banks and/or diversion drains to minimise the potential for storm water runoff to enter disturbed areas.
- F18
The holder of the environmental authority must design, install and maintain adequate erosion and sediment control structures wherever necessary to prevent or minimise erosion of disturbed areas and the sedimentation of any watercourse, waterway, wetland or lake. Topsoil stockpile
- F19
The holder of the environmental authority must ensure that topsoil is removed and stockpiled prior to carrying out any mining activity. Prevent or minimise the mixing and erosion of topsoil and overburden stockpiles. Mineral waste management plan
- F20
The holder of this environmental authority must create a Waste Rock Management Plan. This plan must be: a) Undertaken by an appropriately qualified person; b) Maintained over the course of the life of the operation; c) Have a minimum sample rate of three (3) samples for every 10,000 tonnes of mineral waste; d) Inclusive of ongoing geochemical testing, plus kinetic testing; e) Inclusive of quantification of the volumes of each rock - particularly any acid producing rock and propensity to generate acid mine drainage; and f) Inclusive of consideration and detection of other forms of mine drainage - e.g. saline, neutral/metalliferous and alkaline drainage.

Records demonstrating that each impact to a prescribed environmental matter not listed in Table G1- Significant Residual Impacts to Prescribed Environmental Matters did not, or is not likely to, result in a significant residual impact to that matter must be: a) completed by an appropriately qualified person; and b) kept for the life of the environmental authority.
- G3
An environmental offset made in accordance with the Environmental Offsets Act 2014 and Queensland Environmental Offsets Policy, as amended from time to time, must be undertaken for the maximum extent of impact to each prescribed environmental matter authorised in Table G1 -Significant Residual Impacts to Prescribed Environmental Matters.
- G4
A notice of election for the environmental offset is required to be provided to the administering authority no less than three months before the proposed commencement of the significant residual impacts for which the environmental offset is required.
- G5
Within six (6) months from the completion of the final stage of the project, a report completed by an appropriately qualified person, that includes the following matters must be provided to the administering authority: a) an analysis of the actual impacts on prescribed environmental matters resulting from the final stage; and b) if applicable, a notice of election to address any outstanding offset debits for the authorised impacts. END OF SCHEDULE G Permit Environmental authority Schedule H: Definitions Words and phrases used throughout this environmental authority are defined below. Where a definition for a term used in this environmental authority is not provided within this environmental authority but is provided in the EP Act or subordinate legislation, the definition in the EP Act or subordinate legislation must be used. `administering authority' is the agency or department that administers the environmental authority provisions under the Environmental Protection Act 1994. `airblast overpressure' means energy transmitted from the blast site within the atmosphere in the form of pressure waves. The maximum excess pressure in this wave, above ambient pressure is the peak airblast overpressure measured in decibels linear (dBL). `appropriately qualified person' means a person who has professional qualifications, training, skills or experience relevant to the nominated subject matter and can give authoritative assessment, advice and analysis on performance relating to the subject matter using the relevant protocols, standards, methods or literature. `background', with reference to the water schedule means the average of samples taken prior to the commencement of mining from the same waterway that the current sample has been taken. `blasting' means the use of explosive materials to fracture: a. rock, coal and other minerals for later recovery, or b. structural components or other items to facilitate removal from a site or for reuse. `chemical' means: a. an agricultural chemical product or veterinary chemical product within the meaning of the Agricultural and Veterinary Chemicals Code Act 1994 (Commonwealth), or b. a dangerous good under the Australian Code for the Transport of Dangerous Goods by Road and Rail approved by the Australian Transport Council, or c. a lead hazardous substance within the meaning of the Workplace Health and Safety Regulation 1997, or d. a drug or poison in the Standard for the Uniform Scheduling of Drugs and Poisons prepared by the Australian Health Ministers' Advisory Council and published by the Commonwealth, or e. any substance used as, or intended for use as: i. a pesticide, insecticide, fungicide, herbicide, rodenticide, nematocide, miticide, fumigant or related product, or ii. a surface active agent, including, for example, soap or related detergent, or iii. a paint solvent, pigment, dye, printing ink, industrial polish, adhesive, sealant, food additive, bleach, sanitiser, disinfectant, or biocide, or iv. a fertiliser for agricultural, horticultural or garden use, or v. a substance used for, or intended for use for mineral processing or treatment of metal, pulp and paper, textile, timber, water or wastewater, or vi. manufacture of plastic or synthetic rubber. `commercial place' means a workplace used as an office or for business or commercial purposes, which is not part of the mining activity and does not include employees' accommodation or public roads.
