Receiving environment monitoring program (REMP) The environmental authority holder must develop and implement a REMP to monitor, identify and describe any adverse impacts to surface water environmental values, quality and flows due to the mining activity. This must include monitoring the effects of the mine on the receiving environment periodically (under natural flow conditions) and while sediment affected water is being discharged from the site. For the purposes of the REMP, the receiving environment is the waters of North Creek and connected or surrounding waterways within ten (10) km downstream of the mine access road. The REMP should encompass any sensitive receiving waters or environmental values downstream of the mining activity that will potentially be directly affected by an unauthorised release of mine affected water.

Annual inspection report Each regulated structure must be inspected each calendar year by a suitably qualified and experienced person.
- H22
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 to ensure the integrity of the regulated structure.

The maximum excess pressure in this wave, above ambient pressure is the peak airblast overpressure measured in decibels linear (dBL). `annual inspection report' means an assessment prepared by a suitably qualified and experienced person containing details of the assessment against the most recent consequence assessment report and design plan (or system design plan): (a) against recommendations contained in previous annual inspections reports; (b) against recognised dam safety deficiency indicators; (c) for changes in circumstances potentially leading to a change in consequence category; (d) for conformance with the conditions of this authority; (e) for conformance with the `as constructed' drawings; (f) for the adequacy of the available storage in each regulated dam, based on an actual observation or observations taken after 31 May each year but prior to 1 November of that year, of accumulated sediment, state of the containment barrier and the level of liquids in the dam (or network of linked containment systems); (g) for evidence of conformance with the current operational plan. `ANZECC' means the Australian and New Zealand Guidelines for Fresh Marine Water Quality 2000. `ANZG' means the Australian and New Zealand Guidelines for Fresh and Marine Water Quality 2018. `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 relative to the subject matter using the relevant protocols, standards, methods or literature. `assess' or `assessed' or `assessment' means by a suitably qualified and experienced person in relation to a consequence assessment of a dam, means that a statutory declaration has been made by that person and, when taken together with any attached or appended documents referenced in that declaration, all of the following aspects are addressed and are sufficient to allow an independent audit at any time: (a) exactly what has been assessed and the precise nature of that assessment;
