- H3
Prior to the commencement of any impacts to a prescribed environmental matter for which an environmental offset is required by Condition H2, an analysis of the estimated maximum extent of impact to each prescribed environmental matter must be provided to the administering authority.
- H4
The analysis required by Condition H3 must be approved by the administering authority before the notice of election, if applicable, is given to the administering authority.
- H5
The notice of election for the environmental offset required by Condition H4 must be provided to the administering authority no less than three (3) months before the proposed commencement of the significant residual impacts for which the environmental offset is required. Permit Environmental Authority EPML00932713 Isaac Plains Coal Mine Definitions 20th percentile flow means the 20th percentile of all daily flow measurements (or estimations) of daily flow over a 10- year period for a particular site. The 20th percentile calculation should only include days where flow has been measured (or estimated), i.e. not dry weather days. accepted engineering standards in relation to dams, means those standards of design, construction, operation and maintenance that are broadly accepted within the profession of engineering as being good practice for the purpose and application being considered. In the case of dams, the most relevant documents would be publications of the Australian National Committee on Large Dams (ANCOLD), guidelines published by Queensland government departments, and relevant Australian and New Zealand Standards. acceptance criteria means the measures by which the actions implemented to rehabilitate the land are deemed to be complete. The acceptance criteria indicate the success of the rehabilitation outcome or remediation of areas which have been significantly disturbed by the mining activities. Acceptance criteria may include information regarding: a) vegetation establishment, survival and succession; b) vegetation productivity, sustained growth and structure development; c) fauna colonisation and habitat development; d) ecosystem processes such as soil development and nutrient cycling, and the recolonisation of specific fauna groups such as collembola, mites and termites which are involved in these processes; e) microbiological studies including recolonisation by mycorrhizal fungi, microbial biomass and respiration; f) effects of various establishment treatments such as deep ripping, topsoil handling, seeding and fertiliser application on vegetation growth and development; g) resilience of vegetation to disease, insect attack, drought and fire; and h) vegetation water use and effects on ground water levels and catchment yields. acid rock drainage means any contaminated discharge 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 mining activity. Queensland Government. AEP means the Annual Exceedance Probability: the probability that at least one event in excess of a particular magnitude will occur in any given year. affected person is someone whose drinking water can potentially be impacted as a result of discharges from a dam or their life can be put at risk due to dwellings or workplaces being in the path of a dam break flood. airblast 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 airblast overpressure measured in decibels linear (dBL). alternative arrangement in relation to a sensitive place or a commercial place, means: a) A written agreement: Permit Environmental Authority EPML00932713 Isaac Plains Coal Mine i. between the environmental authority holder and a third party;
