- G9
The spillway for any dam containing hazardous waste constructed within the operational land must be designed to withstand the peak flow from the spillway design storm in Table G3 - Hydraulic Performance of Regulated Dams.
- G10
Construction of a regulated dam must not be commenced unless: a) The licensee has submitted to the administering authority two copies of a design plan, together with the certification of a suitably qualified and experienced person that the design of the regulated dam will deliver the performance stated in that submitted design plan and that dam is compliant in all respects with this environmental authority, and b) At least twenty (20) business days has passed since the receipt of those documents, or the administering authority notifies the licensee that a design plan and certification has been submitted for that dam.
- G11
Every regulated dam must be constructed in accordance with a certified design plan that has been submitted to the administering authority, and such that the resulting dam will deliver the performance stated in that submitted design plan and that dam is compliant in all respects with this environmental authority.
- G12
When construction of any regulated dam is complete and prior to commencing operation of that dam, the licensee must submit to the administering authority two copies of a set of `as constructed' drawings, together with the certification of a suitably qualified and experienced person that the dam `as constructed' will deliver the performance stated in that submitted design plan and that dam is compliant in all respects with this environmental authority.
- G13
An operational plan must be kept current for each regulated dam.
- G14
Where an operational plan covers decommissioning and rehabilitation, those operations are to be consistent with the design plan for the dam and the rehabilitation requirements of this environmental authority.
- G15
The holder of the environmental authority must mark the mandatory reporting level (MRL) defined in Table G3 - Hydraulic Performance of Regulated Dams on the upstream side of the spillway of any dams containing hazardous waste within the operational land.
- G16
The licensee must notify the administering authority as soon as possible, but within twenty-four (24) hours, of the level in any regulated dam reaching the MRL; and must immediately act to prevent or minimize any actual or potential environmental harm. OFFICIAL Permit Environmental authority EPML00715513 Standards and Criteria
- G17
The holder of the environmental authority must design, construct, repair, maintain, operate and decommission the dams containing hazardous and non-hazardous waste in accordance with the criteria outlined in Appendix B of the Code of Environmental Compliance for Mining Lease Projects.
- G18
High hazard dams containing hazardous waste shall be inspected by a Registered Professional Engineer Queensland (RPEQ) during the month of September each year or at any time if alarming, unusual or otherwise unsatisfactory conditions are observed.
- G19
At each annual inspection, the condition and adequacy of each regulated dam must be assessed for dam safety and against the necessary structural, geotechnical and hydraulic performance criteria.
- G20
At each annual inspection, if a MRL is required, it must be determined and marked on each regulated dam.
- G21
For each annual inspection, two copies of a report on the condition and adequacy of each regulated dam, certified by the suitably qualified and experienced person and including any recommended actions to be taken to ensure the integrity of each regulated dam must be provided to the administering authority within ninety (90) days of the inspection.
- G22
The holder of the environmental authority must, promptly, but within one (1) month of receipt of the annual inspection report, formulate and implement actions to ensure that each regulated dam safely performs its intended functions.

"appropriately qualified person" means any person who conforms to the EPA operational policy for an "appropriately qualified person (analyst)" in accordance with Section 490(7) of the Environmental Protection Act 1994. "authority" means environmental authority (mining activities) under the Environmental Protection Act 1994. "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. "commercial place" means a work place 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. "contaminated land" means land contaminated by a hazardous contaminant. "dam" means a containment or proposed containment whether permanent or temporary, which is designed to contain, divert or control flowable substances. However this does not include a fabricated or manufactured tank or container designed to a recognised standard. "design plan" in the context of a dam design is the documentation required under the Code of Environmental Compliance for High Hazard Dams Containing Hazardous Waste to describe the physical dimensions of the dam, the materials and standards to be used for construction of the dam, the procedures and criteria to be used for operating the dam and the decommissioning and rehabilitation objectives in terms procedures, works and outcomes at the end of dam life, The documents can include design and investigation reports, drawings, specifications and certifications. "environmental authority holder" means the holder of this environmental authority. "environmental offset" has the meaning in section 7 of the Environmental Offsets Act 2014.
