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. _____________________________________________________________________________________________________________

Permit Environmental authority EPML00594013 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.

Permit Environmental authority EPML00594013 Definitions Key terms and/or phrases bolded in this environmental authority are defined in this section. 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.

Where required, interpretation of this authority should be in the context of the EMOS. "acceptance criteria" means standards by which actions implemented to rehabilitate land are deemed to be complete. "administering authority" is the agency that administers the environmental authority provisions under the Environmental Protection Act 1994. "airblast overpressure" means energy transmitted from blasting through the atmosphere in the form of pressure waves. The maximum excess pressure in which a wave above ambient pressure is the peak airblast overpressure measured in decibels linear (dBL). "ambient (or total) noise" means the levels of noise at a place from all sources, measured as the Leq for a relevant time interval. "authority" means the environmental authority (mining activities) under the Environmental Protection Act 1994. "b/g" means relevant background sound level measured in accordance with the administering authority's Noise Manual. "blasting" means the use of explosive materials to fracture: 1. rock, coal and other minerals for later recovery 2. structural components or other items to facilitate removal from a site or for reuse. "commercial place" means a place used as an office or for business or commercial purposes, which is not part of the mining activity and does not include employees' accommodation or public roads. "competent person" means a person with sufficient demonstrated skill, knowledge and qualifications required to carry out a task to a necessary standard for protection of the environment. "holder" for a mining tenement, means the holder of the tenement under the Minerals Resources Act 1989, and the holder of the associated environmental authority under the Environmental Protection Act 1994. "infrastructure" means water storage dams, levees, roads and tracks, buildings and other structures built for the purpose of mining activity. "LA1,adj, 10mins" means the A-weighted sound pressure level, (adjusted for tonal characteristics and impulsiveness of the sound) exceeded for 1% of any 10 minute measurement period, using Fast response. "LAeq, 1hour" means the time-averaged A-weighted sound pressure level over a one hour measurement period. ___________________________________________________________________________________________________________

Permit Environmental authority EPML00594013 "LA, max adj, T" means the average maximum A-weighted sound pressure level, adjusted for tonal or impulsive noise character, and measured over any 10 minute period, using Fast response.
