Where a term is not defined, the definition in the Environmental Protection Act 1994, its regulations or environmental protection policies must be used. If a word remains undefined it has its ordinary meaning. "50th percentile long term" means that not more than twenty-six (26) of the measured values of the quality characteristic are to exceed the stated release limit for any fifty-two (52) consecutive samples where: (a) the consecutive samples are taken over a one (1) year period; (b) the consecutive samples are taken at approximately equal periods; and (c) the time interval between the taking of each consecutive sample is not less than three (3) days or greater than eleven (11) days. "50th percentile short term" means not more than five (5) of the measured values of the quality characteristic are to exceed the stated release limit for any ten (10) consecutive samples for a release/monitoring point at any time during operation. "acceptance criteria" means the measures by which actions implemented are deemed to be complete. The acceptance criteria indicate the success of the decommissioning and rehabilitation outcomes or remediation of areas which have been significantly disturbed by the environmentally relevant activities. Acceptance criteria may include information regarding: (a) stability of final land forms in terms of settlement, erosion, weathering, pondage and drainage; (b) control of geochemical and contaminant transport processes; (c) quality of runoff waters and potential impact on receiving environment; (d) vegetation establishment, survival and succession; (e) vegetation productivity, sustained growth and structure development; (f) fauna colonisation and habitat development; (g) ecosystem processes such as soil development and nutrient cycling, and the re-colonisation of specific fauna groups such as collembola, mites and termites which are involved in these processes; (h) microbiological studies including re-colonisation by mycorrhizal fungi, microbial biomass and respiration; (i) effects of various establishment treatments such as deep ripping, topsoil handling, seeding and fertiliser application on vegetation growth and development; (j) resilience of vegetation to disease, insect attack, drought and fire; (k) vegetation water use and effects on ground water levels and catchment yields. "acid and metalliferous mine drainage (AMD)" means any contaminated release emanating from a mining operation formed through a series of chemical and biological reaction, when geological strata is disturbed and exposed to oxygen and moisture as a result of the mining activity. "acid rock drainage (ARD)" means any contaminated release emanating from a mining activity formed through a series of chemical and biological reactions, when geological strata is disturbed and exposed to oxygen and moisture as a result of the mining activity. Environment and Resource Management) or its successor. "affected land" means land on which an event has caused or threatens serious or material environmental harm. "affected person" is someone whose drinking water can potentially be impacted as a result of discharges from a dam or their life or property can be put at risk due to dwellings or workplaces being in the path of a dam break flood. Permit OFFICIAL Environmental Authority EPML00899613 "air blast overpressure" means energy transmitted from the blast site within the atmosphere in the form of pressure waves. The maximum excess pressure in this wave, above ambient pressure is the peak air blast overpressure measured in decibels linear (dBL). "ambient (or total) noise" at a place, means the level of noise at the place from all sources (near and far), measured as the Leq for an appropriate time interval. "Annual Exceedance Probability" or "AEP" the probability that at least one event in excess of a particular magnitude will occur in any given year. "ANZECC 2000" means Australian and New Zealand Environment Conservation Council Marine and Freshwater Quality Guidelines. "ANZG 2018" means the Australian and New Zealand Guidelines for Fresh and Marine Water Quality (Water Quality Guidelines) revised in 2018. Since 2018, the Water Quality Guidelines are presented in an interactive online platform at "www.waterquality.gov.au/guidelines". All default guideline values (DGVs) published on this interactive resource are referred to as ANZG (2018) irrespective of their official publication date. Some guidelines in ANZG (2018) still refer to ANZECC (2000). These are considered ANZG (2018). "appropriately qualified person" means a person who has professional qualifications, training, skills and 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. "assessed" and "assessment" by a suitably qualified and experienced person in relation to a consequence assessment of a structure, 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
