Schedule G - Regulated Dams
- G1
The only regulated dam authorised under this environmental authority is the Flood Protection Levee. Certification and operation
- G2
Documentation required by the conditions in this schedule must be kept available for inspection by the regulating authority for a period of five (5) years after the conclusion of the environmentally relevant activity in respect of which this environmental authority has been granted.
- G3
The holder of this environmental authority must not commence construction of a regulated dam unless: a) the holder 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 is fit for the purpose for that dam stated in that plan, and compliant in all respects with this environmental authority; and b) at least 28 days has passed since the submission of the design plan, or the regulating authority has advised the holder that the design plan is compliant with this condition.
- G4
When construction or modification of any regulated dam is complete, or within twelve (12) months of a dam becoming a regulated dam by virtue of a hazard assessment, the holder of this environmental authority must submit to the administering authority two copies of a set of `as constructed' drawings, together with the certification by a suitably qualified and experienced person that the dam `as constructed' is fit for the purpose stated in the hazard assessment and the design plan if the latter exists, and compliant in all respects with this environmental authority.
- G5
The holder of this environmental authority must ensure that there is always a current operational plan for each regulated dam, which may form part of other plans required by legislation.
- G6
The operational plan shall at least cover all matters relevant to the operation and maintenance of the regulated dam so that it is compliant in all respects with this environmental authority.
- G7
The holder of this environmental authority must ensure that, where a current operational plan covers decommissioning and rehabilitation, those operations are consistent with the objectives in any design plan for the dam. Annual inspection and report
- G8
The holder of this environmental authority must arrange for each regulated dam to be inspected annually by a suitably qualified and experienced person, in accordance with the following conditions. Permit Environmental authority EPPR00585813
- G9
At each annual inspection, the condition of each regulated dam must be assessed, including the structural, geotechnical and hydraulic adequacy of the dam and the adequacy of the works with respect to dam safety, and any recommended actions conveyed immediately to the holder of this environmental authority.
- G10
The holder of this environmental authority must immediately act upon recommendations arising from an annual inspection on condition and adequacy of a dam.
- G11
A final assessment of adequacy of available storage in each regulated dam must be based on a dam level observed within the month of October, accepted as valid by the suitably qualified and experienced person, and resulting in an estimate of the level in that dam as at 1 November.
- G12
For each annual inspection, two copies of a report certified by the suitably qualified and experienced person, including any recommended actions to be taken to ensure the integrity of each regulated dam, must be provided to the administering authority by 1 December.
- G13
The Design plan in accordance with condition G3 must include: a) drawings describing the location and dimensions of the levee and the mining excavations in the vicinity of the levee, including confirmation the levee meets the specified design requirements in condition G14; and b) a documented procedure for surveillance of the levee and any adjacent mining excavation slopes to detect and report to the administering authority any ground movement that compromises or may compromise the integrity of the levee.
- G14
Design requirements for the levee and adjacent mining excavation include: a) the design level of the levee crest shall be 0.5m above the predicted 2,000 year Average Recurrence Interval (ARI) event flood level. If the construction of the levee is staged, the level of the crest within those parts of the levee may be reduced to maintain a constant probability of overtopping. The risk of overtopping must not be greater than 2.5% during the life of the levee; and b) mining excavation slopes adjacent to the levee must remain stable and are to be designed with a factor of safety of 1.5 or above based on an accepted stability analysis.
- G15
The flood protection levee authorised under this environmental authority must be constructed and maintained such that: a) it does not result in erosion of the bank or bed of Roper Creek or Thirteen Mile Gully; b) it does not significantly impact upon riparian or existing remnant vegetation; and c) it will not erode during any flood events. Permit Environmental authority EPPR00585813
- G16
The design specifications of the flood protection levee shall be determined by the predicted 1-in-2,000 year flood level, plus 0.5m and shall be provided with all design plans in accordance with conditions G3 and G4. Flood Protection Levee - Surveillance and Remedial Works
- G17
The condition of constructed levees including the surface area between the non-creek side of the toe of the levee and the endwall crest of the open-cut mining pit should be monitored for surface cracks and must at a minimum be inspected and assessed by a suitably qualified and experienced person at least once per year between the months of May and October inclusive (i.e. during the `dry' season and before the onset of the `wet' season), and at any time if alarming, unusual or otherwise unsatisfactory conditions are observed.
- G18
For each inspection, two copies of the surveillance report, including any recommendations for remedial works, must be provided to the administering inspection within twenty-eight (28) days of the date of inspection.
- G19
Remedial works identified as being required for the flood protection levee during the inspections and assessments conducted under conditions G8 and G8, must be notified in writing to the administering authority within 5 business days of the completion of the inspections, and commenced within twenty-eight (28) days unless otherwise agreed in writing by the administering authority.
- G20
The annual return for this environmental authority shall be accompanied by a report, by a suitably qualified and experienced person, that certifies that the documented procedure for surveillance of the levee has been applied in accordance with the procedure, that there has been no erosion, cracking or vertical or horizontal deformation that has impacted on the integrity of the levee, and that the levee has been maintained in accordance with the certified design plan.
