Operation of a regulated structure must not commence unless the environmental authority holder has submitted to the administering authority: a) One paper copy and one electronic copy of the design plan and certification of the `design plan' in accordance with condition H7, and b) A set of `as constructed' drawings and specifications, and c) Certification of those `as constructed drawings and specifications' in accordance with condition H9, and d) Where the regulated structure is to be managed as part of an integrated containment system for the purpose of sharing the design storage allowance (DSA) volume across the system, a copy of the certified system design plan; e) A statement that confirms: i) The requirements of this authority relating to the construction of the regulated structure have been met; ii) The details required under this authority, have been entered into a Register of Regulated Structures; and iii) There is a current operational plan for the regulated structures.
- H11
For existing structures that are regulated structures: a) where the existing structure that is a regulated structure is managed as part of an integrated containment system for the purpose of sharing the DSA volume across the system, the environmental authority holder must submit to the administering authority within three (3) months of the commencement of this condition a copy of the certified system design plan including that structure; and b) There must be a current operational plan for the existing structures.
- H12
Each regulated structure must be maintained and operated, for the duration of its operational life until Permit Environmental authority decommissioned and rehabilitated, in a manner that is consistent with the current operational plan and, if applicable, the current design plan and associated certified `as constructed' drawings. Mandatory reporting level
- H13
Conditions H14 to H17 inclusive only apply to Regulated Structures which have not been certified as low consequence category for `failure to contain - overtopping'.
- H14
The Mandatory Reporting Level (the MRL) specified in Table H1 must be marked on a regulated structure in such a way that during routine inspections of that structure, it is clearly observable.
- H15
The environmental authority holder must, as soon as practical and within forty-eight (48) hours of becoming aware, notify the administering authority when the level of the contents of a regulated structure reaches the MRL.
- H16
The environmental authority holder must, immediately on becoming aware that the MRL has been reached, act to prevent the occurrence of any unauthorised discharge from the regulated structure.
- H17
The environmental authority holder must record any changes to the MRL in Table H1 and in the Register of Regulated Structures. Design storage allowance
- H18
The environmental authority holder must assess the performance of each regulated structure or linked containment system over the preceding November to May period based on actual observations of the available storage in each regulated structure or linked containment system taken prior to 1 July of each year.
- H19
By 1 November of each year, storage capacity must be available in each regulated structure (or network of linked containment systems with a shared DSA volume), to meet the Design Storage Allowance (DSA) volume for the structure (or network of linked containment systems), as specified in Table H1.
- H20
The environmental authority holder must, as soon as possible and within forty-eight (48) hours of becoming aware that the regulated structure (or network of linked containment systems) will not have the available storage to meet the DSA volume on 1 November of any year, notify the administering authority.
- H21
The environmental authority holder must, immediately on becoming aware that a regulated structure (or network of linked containment systems) will not have the available storage to meet the DSA volume on 1 November of any year, act to prevent the occurrence of any unauthorised discharge from the regulated structure or linked containment systems. Annual inspection report
- H22
Each regulated structure must be inspected each calendar year by a suitably qualified and experienced person.
- H23
At each annual inspection, the condition and adequacy of all components of the regulated structure must be assessed and a suitably qualified and experienced person must prepare an annual inspection report containing details of the assessment and include recommended actions, if applicable, to ensure the integrity of the regulated structure.
- H24
The suitably qualified and experienced person who prepared the annual inspection report must certify the report in accordance with the Manual for assessing consequence categories and hydraulic Permit Environmental authority
- H25
The environmental authority holder must within 20 business days of receipt of the annual inspection report, provide to the administering authority: a) The recommendations section of the annual inspection report; and b) If applicable, any details of any actions being taken in response to those recommendations. Transfer arrangements
- H26
The environmental authority holder must provide a copy of any reports, documentation and certifications prepared under this authority, including but not limited to any Register of Regulated Structures, consequence assessment, design plan and other supporting documentation, to a new holder on transfer of this authority. Decommissioning and rehabilitation
- H27
Regulated structures must not be abandoned but must be decommissioned and rehabilitated to achieve compliance with the Progressive Rehabilitation Closure Plan schedule . Transitional arrangements
- H28
All existing structures that have not been assessed in accordance with the Manual for assessing and certified in accordance with the Manual for assessing consequence categories and hydraulic Hydraulic performance of regulated structures
- H29
Each regulated structure authorised by this environmental authority as specified in Table A1 Authorised Disturbance, must meet the hydraulic performance criteria listed in Table H1 for that structure. Table H1 - Hydraulic performance criteria (`Table H1') Spillway Design Storage Mandatory Capacity Allowance (DSA) Name of Consequence Reporting Level Regulated Category Structure (MRL) Purpose of structure Design mAHD Design mAHD Design mAHD Capture seepage from Criteria 243 Criteria RL 239m Criteria existing Waste Rock Dump Evaporation Significant 1 in 100 1 in 20 AEP 1 in 10 RL Pond AEP 3 month AEP 72hr 237.3m duration wet season
- H30
The hydraulic performance criteria specified in Table H1 are the minimum mandatory performance requirements; regulated structures must be managed in a manner that ensures compliance with all conditions of this environmental authority.
