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(s) must prepare an annual inspection report containing details of the assessment and include recommended actions to ensure the integrity of the regulated structure.

The suitably qualified and experienced person(s) who prepared the annual inspection report must certify the report in accordance with the Manual for Assessing Consequence Categories and Hydraulic Performance of Structures (EM635).

Transitional arrangements All existing structures that have not been assessed in accordance with either the Manual or the former Manual for Assessing Hazard Categories and Hydraulic Performance of Dams must be assessed and certified in accordance with the Manual within six (6) months of amendment of the authority adopting this schedule.

All existing structures must subsequently comply with the timetable for any further assessments in accordance with the Manual specified in Table H1 - Transitional Requirements for Existing Structures, depending on the consequence category for each existing structure assessed in the most recent previous certification for that structure.

Table H1 ceases to apply for a structure once any of the following events has occurred: (a) it has been brought into compliance with the hydraulic performance criteria applicable to the structure under the Manual; (b) it has been decommissioned; or (c) it has been certified as no longer being assessed as a regulated structure.

Permit Environmental Authority EPML00900113 Cameby Downs Mine Additional information for applicants Environmentally relevant activities The description of any environmentally relevant activity (ERA) for which an environmental authority (EA) is issued is a restatement of the ERA as defined by legislation at the time the EA is issued. Where there is any inconsistency between that description of an ERA and the conditions stated by an EA as to the scale, intensity or manner of carrying out an ERA, the conditions prevail to the extent of the inconsistency. An EA authorises the carrying out of an ERA and does not authorise any environmental harm unless a condition stated by the EA specifically authorises environmental harm. A person carrying out an ERA must also be a registered suitable operator under the Environmental Protection Act 1994 (EP Act). Contaminated land It is a requirement of the EP Act that an owner or occupier of contaminated land give written notice to the administering authority if they become aware of the following: - the happening of an event involving a hazardous contaminant on the contaminated land (notice must be given within 24 hours); or - a change in the condition of the contaminated land (notice must be given within 24 hours); or - a notifiable activity (as defined in Schedule 3) having been carried out, or is being carried out, on the contaminated land (notice must be given within 20 business days); that is causing, or is reasonably likely to cause, serious or material environmental harm. For further information, including the form for giving written notice, refer to the Queensland Government website www.qld.gov.au, using the search term `duty to notify'. Take effect Please note that, in accordance with section 200 of the EP Act, an EA has effect: a) if the authority is for a prescribed ERA and it states that it takes effect on the day nominated by the holder of the authority in a written notice given to the administering authority-on the nominated day; or b) if the authority states a day or an event for it to take effect-on the stated day or when the stated event happens; or c) otherwise-on the day the authority is issued. However, if the EA is authorising an activity that requires an additional authorisation (a relevant tenure for a resource activity, a development permit under the Sustainable Planning Act 2009 or an SDA Approval under the State Development and Public Works Organisation Act 1971), this EA will not take effect until the additional authorisation has taken effect. If this EA takes effect when the additional authorisation takes effect, you must provide the administering authority written notice within 5 business days of receiving notification of the related additional authorisation taking effect. If you have incorrectly claimed that an additional authorisation is not required, carrying out the ERA without the additional authorisation is not legal and could result in your prosecution for providing false or misleading information or operating without a valid environmental authority.

The review must consider: (a) the frequency and cause of any exceedances of air quality objectives measured by the monitoring program over a period of at least two (2) years; (b) dust complaints; (c) future progression of the mining activities; (d) locations of sensitive receptors relative to the mining activities; and (e) all stages of mining. B8 Odour Nuisance The release of noxious or offensive odour(s) or any other noxious or offensive airborne contaminant(s) resulting from the mining activity must not cause an environmental nuisance at any sensitive or commercial place. B9 When requested by the administering authority, odour monitoring must be undertaken within a timeframe agreed to by the administering authority to investigate any complaint (which is neither frivolous nor vexatious, nor based on mistaken belief, in the opinion of the authorised officer) of environmental nuisance at any sensitive or commercial place, and the results must be notified within fourteen (14) days to the administering authority following completion of monitoring.
