Permit Environmental Authority - Ironbark No 1 Coal Mine Additional information for applicants Environmentally relevant activities The description of any environmentally relevant activity (ERA) for which an environmental authority (EA) is issued is a restatement of the ERA as defined by legislation at the time the EA is issued. 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. A person carrying out an ERA must also be a registered suitable operator under the Environmental Protection Act 1994 (EP Act). Mobile and temporary activities If you operate a mobile and temporary ERA, other than regulated waste transport, you are required to maintain a work diary. You must: - keep the work diary records for 2 years after the last entry; - inform the administering authority within 7 days of the work diary being lost or stolen; - record the information required in the work diary for each location within 1 day of leaving the location. Contaminated land It is a requirement of the EP Act that an owner or occupier of land give written notice to the administering authority if they become aware of the following: - the presence of, or happening of an event involving, a hazardous contaminant on the land that is causing, or is reasonably likely to cause, serious or material environmental harm (notice must be given within 24 hours); or - if the land is contaminated land - a change in the condition of the land that is causing, or is reasonably likely to cause, serious or material environmental harm (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 land (notice must be given within 20 business days). 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(1) 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;
