If a word remains undefined it has its ordinary meaning. `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. `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 airblast overpressure measured in decibels linear (dBL). `Annual exceedance probability' or `AEP' means the probability that at least one event in excess of a particular magnitude will occur in any given year. `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 relating 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 hazard 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 of the assessment: a) exactly what has been assessed and the precise nature of that determination; b) the relevant legislative, regulatory and technical criteria on which the assessment has been based; c) the relevant data and facts on which the assessment has been based, the source of that material, and the efforts made to obtain all relevant data and facts; and d) the reasoning on which the assessment has been based using the relevant data and facts, and the relevant criteria. `associated works' means in relation to a dam, a) operations of any kind and all things constructed, erected or installed for that dam; and b) any land used for those operations. `authority' means an environmental authority. `background', with reference to the water schedule means the average of samples taken prior to the commencement of mining from the same waterway that the current sample has been taken. `blasting' means the use of explosive materials to fracture: a) rock, coal and other minerals for later recovery; or b) structural components or other items to facilitate removal from a site or for reuse. `certification' means assessment and approval must be undertaken by a suitably qualified and experienced person in relation to any assessment or documentation required by this manual, including design plans, `as constructed' drawings and specifications, construction, operation or an annual report regarding regulated structures, undertaken in accordance with the Board of Professional Engineers of Queensland Policy Certification by RPEQs (ID: 1.4 (2A)). `certifying', `certify' or `certified' have a corresponding meaning as `certification'. Permit Environmental Authority `chemical' means: a) an agricultural chemical product or veterinary chemical product within the meaning of the Agricultural and
